Description

The invention relates to a supply unit for a patient room according to the preamble of claim 1.

Usually supply units in rooms, in particular in patient rooms, are used to connect connections in the room, in particular beds provided via connections, via supply lines with line systems. Conventional supply units comprise a profile-like housing for wall or ceiling mounting, which is designed to receive supply lines and extends in an elongated longitudinal direction. A supply unit can thus be mounted on a wall or a ceiling of a room via the housing and supply lines can be arranged in the housing, which connect the connections to the supply unit to the line systems. In some embodiments of known supply units, the housing is suitable for receiving gas lines and electrical lines. The housing is elongated in a longitudinal direction, which means that the housing has a substantially greater extent in the longitudinal direction than in the perpendicular to the Longitudinally aligned transverse direction. The ratio between the longitudinal extent and the transverse extent of a housing may in some embodiments be 5: 1, in some embodiments 10: 1 or even greater. For further features of the profile-like housing of conventional, generic supply units is on the documents EP 1 073 172 B1 and EP 1 096 629 A1 in particular to [0001] to [0003], [0008] to [0014] and the description of the figures of the EP 1 073 172 B1 and [0002] to [0003], [0007] to [0010] and the description of the figures of EP 1 096 629 A1 ,

Generic supply units have at least one luminaire with at least one luminous means unit which comprises at least one luminous means. In particular, supply units are known which have at least one luminous means unit, which comprises a plurality of luminous means, which are arranged in particular in a section in the longitudinal direction next to one another. The illuminant unit may for example be designed so that it allows a room backlighting, in other examples, the illuminant unit can emit light in a certain area of space, for example, to ensure the function of a reading light. Usually, the lighting unit is arranged in the housing of the supply unit or has its own light source housing, which is connected to the housing of the supply unit. The number of lamps of the lamp unit and the arrangement of the lamps in the lamp unit is set according to the desired purpose to be achieved with the lamp unit. The illuminant unit may in particular comprise at least two bulbs arranged side by side in the longitudinal direction. The portion in which the bulbs are arranged extends along the Longitudinal direction. The lighting means can also be arranged offset from one another in the transverse direction, in particular a surface can be spanned across the transverse direction and the longitudinal direction in which the lighting means are distributed. In particular, the lighting means can also be arranged one above the other in the transverse direction, wherein such rows of lamps arranged one above the other in the transverse direction can be arranged side by side in the longitudinal direction. In addition, a control unit for controlling the at least one lighting unit is usually provided in the supply unit, in particular in the lamp, via which at least the switching on and off of the lighting unit is controllable.

A special further development of conventional supply units is from the document EP 0 739 618 B1 known. In this supply unit, the illuminant unit is arranged displaceably in the longitudinal direction on the housing of the supply unit, so that the position of the area illuminated by the illuminant unit in the room can be correspondingly displaced by displacing the illuminant unit in the longitudinal direction. In this supply unit is thus a displaceability of the illuminated area for adjusting the illumination of the furniture arrangement in the room and the desired by persons in the room illumination characteristic possible. This takes place in this supply unit via a mechanical displacement of the lamp unit along the housing of the supply unit. Further, in the document JP 2004 154372 A discloses a supply unit having two lights that can be turned on independently. This document also discloses, as an alternative embodiment, a lamp unit to be arranged displaceably in the longitudinal direction on the housing of the supply unit. In the document US 2013/0085609 A1 discloses a system comprising a plurality of supply units, in which individual adjustments of the supply unit are made by the recognition of a user to the user.

The described conventional supply units have several disadvantages. On the one hand, it is possible with the described supply units only with the help of an additional dimming device, the illumination intensity, ie the intensity of the Illuminant units of the supply unit radiated light, so that the illumination intensity is not adapted to the particular situation in the room, such as a reading situation, a situation in which a low backlight is desired, or a study situation in which a doctor, a patient, for example in his bedside, being examined in a room, can be adjusted. In addition, a shift of the area illuminated by the illuminant unit (s) of the supply unit can only take place via a mechanical displacement of the illuminant unit along the housing of the supply unit. For this purpose, a costly mechanical storage of the lighting unit or the lighting units on the housing of the supply unit is required, and the shift is not usually feasible by a patient lying in the bed itself but must be performed by a nurse. In addition, such storage of lighting units connected to the housing with hygienic disadvantages, since the storage can not be kept clean as desired.

The invention has for its object to provide a supply unit, which at least partially solves the problems described above in known supply units.

As a solution of said technical problem, the invention proposes a supply unit with the features of claim 1. The supply unit according to the invention is characterized in that within the section in which the lighting means are arranged side by side in the longitudinal direction, a plurality, ie at least two, lighting element groups are provided, which in the longitudinal direction are arranged side by side, wherein each group of lamps comprises at least one of the lamps of the lamp unit and wherein the lamp groups are independently controlled by the control unit.

An illuminant group can comprise one or more illuminants. One or more bulbs are associated with a group of bulbs. One or more groups of lamps are assigned to a lighting unit. The assignment is ensured by the control unit. For example, the lamps of a group of lamps can be offset in the transverse direction but arranged in the longitudinal direction on a straight line to each other. By way of example, the lighting means of a lighting group can be arranged next to one another offset both in the transverse direction and in the longitudinal direction. In one embodiment, the lamp groups of the lamp unit overlap in the longitudinal direction. In this exemplary embodiment, the lighting means groups are arranged next to one another in the sense that the longitudinal centers of the lighting means groups are arranged next to one another. In one exemplary embodiment, all the lighting means groups have the same longitudinal length. In one embodiment, a plurality of lighting units are provided, which are offset from each other in the transverse direction. For example, at least some of the lighting unit of the supply unit can emit light in a respective other emission direction. In one embodiment, the supply unit has a plurality of lamp units, wherein the lamp units are arranged offset from one another in the longitudinal direction. In one embodiment, the staggered arrangement of the illuminant units may consist in that illuminants of one illuminant unit are arranged offset to illuminants of the other illuminant unit. In one Embodiment, the illuminant units do not overlap in the longitudinal direction. In one embodiment overlap, ie overlap the lamp units in the longitudinal direction at least partially. The embodiments are correspondingly applicable to transversely arranged side by side illuminant units. The statements are applicable to side by side or mutually offset lamp groups.

In particular, the features of the described embodiment can be combined with one another. According to the invention, at least one of the illuminant units, in particular a plurality of the illuminant units, has a plurality of illuminant groups. In one embodiment, the supply unit according to the invention comprises at least two lights. The invention further relates to a luminaire according to the invention with at least one luminous means, which comprises a plurality of light sources, in particular LEDs, which are arranged side by side in a section in the longitudinal direction, and a control unit for controlling the at least one light-emitting unit, wherein within the section a plurality of light source groups are provided, which are arranged next to one another in the longitudinal direction, each illuminant group comprising at least one of the illuminants of the illuminant unit, and wherein the illuminant groups are independently controllable by the control unit. The luminaire according to the invention may have at least one of the features described in the present description with regard to the supply unit according to the invention as being preferably contained. The supply unit according to the invention may comprise a plurality of lights according to the invention, each having different feature combinations according to the invention. For example, the Supply unit according to the invention or one of the lights of the supply unit according to the invention comprise a control unit, via which the control of all lights of the supply unit is ensured.

The control unit enables independent control of the different groups of lamps. As a result, one or more specific groups of lamps can be selected in a targeted manner via the control unit, so that only these groups of lamps emit light. Thus, via the control unit, a desired emission characteristic and / or a desired illumination range, which is ensured by the lighting means of the supply unit, can be set. Thus, in the case of the supply unit according to the invention, the illumination characteristic can be adapted to the respective situation and the respective wishes of the person in the room, without having to mechanically influence the supply unit and / or the lighting unit. Rather, the emission characteristic can be adjusted purely electronically via the control unit. As a result, the supply unit according to the invention brings considerable advantages. For example, a simple and inexpensive mounting of the lighting unit to the housing of the supply unit may be possible. For example, a very simple adjustment of the emission characteristic of the light emitted by the lighting means of the supply unit may be possible. For example, the setting can be made via an actuating element that is electronically connected to the control unit. As a result, a person, for example a patient or a nurse, can influence the illumination of the room by actuating the actuating element. In addition, the supply unit according to the invention ensures hygienic advantages, since the supply unit are formed can be easily kept clean because no complicated mechanical bearings are necessary, which connect the lamp unit or the lamp units to the housing of the supply unit.

In a particularly advantageous embodiment, LEDs are provided as the light source. Due to their compact design, LEDs can be integrated into the supply unit in a particularly simple and visually appealing way. In addition, LED modules are particularly easy to control electronically. In one embodiment, the lighting unit is designed as an LED strip, wherein the LEDs in groups, ie as groups of lamps, can be controlled separately from each other. In particular, when using LEDs as the light source, it is possible to produce the illuminant unit separately from the supply unit as a complete LED module and to tune it to a control unit, so that the production of the supply unit according to the invention can be particularly simplified since only an integration of the complete LED Module needs to be implemented in the supply unit, the LED module is already tuned with the control unit of the supply unit. In one embodiment, LEDs with different colors of light may be provided. In one exemplary embodiment, various illuminant units are provided, which each have exclusively LEDs with a specific light color. As a result, for example, a different light color can be ensured in different emission areas. In one embodiment, light-emitting device groups are provided in the lighting unit, which have LEDs with different light color. By the separate control of the lighting groups, for example, the color with which the room in which the supply unit is arranged, is illuminated, be changeable.

According to the invention, the control unit is embodied such that a lighting section can be predetermined within a certain longitudinal section length, within which the control unit activates the lighting means for emitting light, wherein the longitudinal position of the lighting section can be adjusted via the control unit. In this case, the longitudinal section length and the longitudinal position for a particular lamp unit, in particular for different lamp units individually, can be set or predefined. By way of example, this embodiment has the advantage that a user can predefine the length of the illumination section, and thus the length of the section in which light sources of the illuminant unit emit light, and can realize a displacement of the illumination section in the longitudinal direction. For example, the longitudinal section length of the lighting section can be changed simultaneously with a change in the longitudinal position of the lighting section, for example, the control unit can be set so that a functional relationship exists between the longitudinal section length of the lighting section and the longitudinal position of the lighting section. In one embodiment, the longitudinal position of the illumination section is adjustable independently of the predetermined longitudinal section length of the illumination section. Thus, for example, a user may first set the lighting section length via the control unit and then vary the position of the lighting section in the longitudinal direction. As a result, it is possible to ensure that the size of the area illuminated by the lighting means of the lighting unit does not change when the longitudinal position of the lighting section is varied is changed. For example, the control unit may be set so that, given a variation of the longitudinal position of the illumination section, the same light intensity of the light emitted by the illumination means in the illumination section is always predetermined. In one embodiment, the longitudinal position of the illumination section may be manually adjusted via an actuator. For example, a slider may be provided on the actuator or keys may be provided on the actuator, such as plus, minus keys as a control, whereby a displacement of the longitudinal position of the lighting section can be manually easily realized.

In one exemplary embodiment, the control unit and the illuminant unit are designed to correspond with one another such that a specific illumination intensity can be predetermined with which the illuminant unit emits light. For example, the illumination intensity may be a parameter that can be set in the control unit. For example, the illumination section length and the longitudinal position of a lighting section of the lighting unit can be changed independently of the predetermined illumination intensity. The specification of the illumination intensity may relate, for example, to the illuminant unit as a whole, so that it is ensured that the predetermined illuminance is always emitted by the illuminant unit via its illuminant. The specification of the illumination intensity can also take place, for example, in that each illuminant of the illuminant unit, which is activated by the control unit, is given a specific illumination intensity with which this illuminant emits light. The illumination intensity, with which the entire lamp unit radiates light, can be varied, for example, by a variation of the number of active, ie radiating bulbs, for example by a variation of the intensity with which activated, ie radiating light emit light. In particular, in one exemplary embodiment, the illumination intensity for each illuminant unit can be set separately so that a given intensity is given to each illuminant unit with which this particular illuminant unit emits light. The embodiments according to the invention, via which a variation of the illumination intensity is possible, allow a particularly good coordination of the illumination intensity, with which all lamps of the supply unit emit light, to the needs of the person in the room in which the supply unit is arranged. For example, for a study of a patient, a higher illumination intensity can be specified than for a backlight (general lighting), for example, a specific, predetermined by the reading person and adjusted to their wishes lighting intensity can be specified for the use of a lighting unit as a reading light.

In one embodiment, the control unit is designed so that the number of activated by the control unit bulbs is adjustable. For example, the illumination intensity provided by the lighting unit controlled by the control unit can thereby be predetermined. For example, this can ensure a pleasant for a person in the room luminous appearance of the lighting unit of the supply unit.

In one embodiment, multiple illuminant units provided, which are offset in at least one transverse direction to each other and / or emit light in each different solid angle ranges. As a result, a particularly good illumination of a room in which the supply unit is arranged can be ensured. In particular, this may possibly illuminate a particularly large solid angle range in the room. Each illuminant unit is compulsorily designed so that it can emit light in a certain solid angle range. Therefore, in one embodiment, the transversely offset arrangement of a plurality of illuminant units illuminates a larger solid angle range in the room. For example, the solid angle ranges into which the respective illuminant units can emit light may overlap. In another exemplary embodiment, the illuminant units are arranged offset in the transverse direction with respect to one another such that their solid angle ranges do not overlap. When providing a plurality of lamp units, it is generally to be considered that not all of these lamp units necessarily have to comprise respective groups of lamps which are arranged next to one another and can be controlled independently of one another by the control unit. Such a longitudinal section controllability can be provided in one embodiment, only for one or some of the lighting units. In other embodiments, all of the illuminant units of the supply units can be controlled according to longitudinal sections.

In one embodiment, the supply unit comprises a plurality of lighting units each having a different light color. As a result, an even greater variation of the emission characteristic, by the supply unit is guaranteed, possible. By way of example, the illuminant units, which each have a different light color, can be designed and arranged on the supply unit in such a way that their solid angle ranges, into which they can emit light, overlap. As a result, a variation of the light color in the corresponding solid angle region, in which the solid angle regions of the light source units overlap with different light color, is possible. In other embodiments, it is also possible to provide different solid angle ranges, in each of which a different number of illuminant units each having a different light color overlap.

In one embodiment, a plurality of lighting units may be provided which perform different functions. For example, at least one of the illuminant units can be designed as a reading light, at least one of the illuminant units as a background light for general lighting, at least one of the illuminant units as a signal light. In one embodiment, the illuminant units each have a different function, in one embodiment, at least some functions exert several illuminant units.

It may be advantageous for the supply unit to have an optical element which is assigned to the lighting unit for predetermining the emission characteristic of the lighting unit. By way of example, one optical element can be assigned to each lighting unit, for example at least one optical element can be assigned to at least a plurality of lighting elements. In other embodiments, an optical element may be associated with a plurality of illuminant units be. In particular, it can be advantageous that illuminant units which can emit light in the same solid angle range in each case are assigned the same optical element. The emission characteristic of the light emitted by the illuminant units of the supply unit can additionally be influenced via the optical element or a plurality of optical elements. For example, a glare can be realized. For example, by the optical element via light diffraction and / or refraction, the direction or the solid angle range, is emitted in the light from the light sources of the light emitting device associated with the optical element.

In one exemplary embodiment, the illuminant unit is arranged within a housing for protection against damage. For example, the housing may be transparent at a certain area. As a result, it can be specified that the illuminant unit emits light in the corresponding direction via the transparent region. The arrangement of the lamp unit in the housing of the supply unit, a particularly simple, inexpensive and easy to keep clean design of the supply unit can be ensured.

The supply unit may comprise an actuating device. In this case, the luminaire of the supply unit may comprise an actuating device with operating elements, which is designed such that control parameters of the control unit for controlling the luminous means of the luminaire can be set manually via the actuating device. For example, the actuating device may be designed so that it is electronically connectable or connected to the control unit, for example via electrical lines or via a wireless Connection. By means of the actuating device, a particularly simple manual control of the lighting unit of the supply unit can be ensured, so that a person can easily adapt the emission characteristic of the lighting unit or the lighting unit to his wishes via the actuating device.

Preferably, the actuator can be firmly connected to the supply unit. For example, the supply unit can be connected to the actuating device via an electrical cable with which signals can be transmitted from the actuating device to the supply unit. The actuator is adapted to suit a patient and / or hospital staff for the adjustment of the light of the supply unit to the environment of the patient, for example, to the needs of the patient or to the needs, which involves an examination of the patient.

At the actuator controls are provided. The controls can be configured for example as a button. The buttons can be mechanically formed, for example. The controls can be realized for example in the form of icons on a touchpad. The person skilled in conventional implementation possibilities of corresponding controls are known. In an advantageous embodiment, the actuating device and its associated control unit are coordinated so that the actuator provides two different modes of operation: In a first actuation mode default settings with respect to the light of the supply unit vornehmbar in the second actuation mode is a simple circuit for use the lamp of the supply unit feasible. For example, different operating elements can be provided for the different operating modes. For example, a different mode of operation of one and the same operating element can be provided for the respective operating modes. In the first operating mode, for example, the maximum brightness of a lighting unit can be set as a basic setting, for example via the maximum number of activatable lighting means of the lighting unit and / or the maximum emission intensity of the light sources. For example, in the first actuation mode as the basic setting of the luminaire, a selection of the luminous element groups of a luminous means unit can be made which can be activated in the second actuation mode. As a result, it is possible, for example, to select a position range in which the illuminant groups activatable in the second actuation mode are located so that the position from which light is emitted by the illuminant unit when the illuminant unit is activated in the second actuation mode can be established. In one embodiment, for example, a control element may be configured so that by a short press, such as a brief mechanical pressing of the button, a switching, ie, for example, a switching on and off in the second operating mode, is feasible, whereas by a long operation of the control in which, for example, a pressing for at least three seconds, a change to the first operating mode is possible, after which setting parameters for the basic setting of the lamp can then be set in the first operating mode by briefly pressing the operating element. For example, the first operating mode for adjusting the basic settings of the lamp in a Embodiment be left by pressing the control again long, in another embodiment by a non-actuation of the control over a certain period, for example, over five seconds.

In an advantageous embodiment, the supply unit according to the invention has a plurality of lights. Each lamp is designed to illuminate an environment of a particular patient. In this embodiment, it may be advantageous that each lamp is assigned a separate control element, so that both the setting of the basic setting of the lamp and the operation of the lamp in the second operating mode can be easily tuned to the desired environment of each patient. In such an embodiment, the supply unit has two control units, wherein each lamp is associated with a specific control unit and each actuator communicates with exactly one of the control units. In another such embodiment, the supply unit has only one control unit, wherein the actuating devices each communicate with the control unit in such a way that an adjustment or circuit of the lamp associated with the respective actuating device is possible via an actuating device via the control unit of the supply unit.

In an advantageous embodiment, the actuating device comprises as operating elements patient operating elements and personal control elements. On the actuator, the controls are marked accordingly. For example, the patient controls and the personal controls also be provided at different locations on the actuator. For example, a handpiece can be provided for the patient operating elements, which is connected with a cable to the supply unit and which the patient can hold in his hand, whereas the personal operating elements are integrated in the housing of the supply unit. In another embodiment, different handpieces may be provided for the patient operating elements and personal control elements, respectively. For example, the patient's handpiece may coincide with the handpiece of a conventional nurse call system integrated with the care unit, the patient controls being provided on the handset of the nurse call system.

The distinction between patient controls and personal controls is meaningful to the effect that the respective controls different control signals can be assigned, which transmit the controls when actuated to the control unit. For example, it can be provided that only via the personal control elements, an operation of the actuating device in the above-described first operating mode is possible with the basic settings of the lamp can be made. For example, the personal control elements and the patient operating elements can each be set so that they output certain predefined signals to the control unit when the actuating device is actuated in the second operating mode for simple switching or operation of the light. For example, via the patient control elements, switching on and off of lamp units and / or dimming of lamp units, ie for example a change in the number of light-emitting lamps of the lamp units or a change in the Intensity, emit light with the bulbs of the lamp units, allows his. For example, personnel controls may be provided, the operation of which cause a particular circuit of the lamp. For example, such a control signal can be assigned to a personal control element, which illuminates the patient environment with maximum brightness, ie that all light-emitting means groups that illuminate the patient environment are activated with all their lighting means. Such a personal control element, for example, allow optimal illumination of the patient environment for an examination of the patient via an actuation of the control element. For example, a further operator control element can be assigned to a night lighting state of the luminaire, so that activation of this operator control element activates groups of illuminants of a luminous means with their luminous means, which enable a discreet, non-disturbing backlighting. By providing personal controls and patient controls thus a particularly simple operation of the light of the supply unit can be ensured because the respective controls certain control signals for controlling the control unit can be assigned, so that by a few steps, possibly by simply pressing only one control a desired Lighting situation can be brought about.

In an advantageous embodiment, a plurality of the operating elements are each designed to prescribe control parameters for exactly one illuminating unit assigned to the respective operating element. This has the advantage that precisely such a lighting unit can be controlled via such a control element, the can provide desired lighting situation. For example, a light-emitting unit can be designed as a reading light, for example, a light-emitting unit can be configured as a backlight for general lighting, which ensures an indirect lighting of the room. By an operating element is assigned to exactly one light emitting unit, just the desired in the particular situation illumination characteristic can be easily adjusted via the one light emitting unit. In particular, it is possible for different operating elements to be assigned to the same lighting unit. For example, an operating element can be assigned to exactly one illuminant unit, wherein a different operating element can be assigned to both this one illuminant unit and another illuminant unit. For example, a control element of the reading light can be assigned, another control element of a maximum possible illumination, for example, a study lighting, so that on the first control only the reading light is adjustable, on the second control the reading light at the same time with all other lights. The assignment of controls to illuminant units allows a particularly simple and quick handling of the light of the supply unit.

Furthermore, in a further exemplary embodiment, a central actuating element can be provided for prescribing control parameters of the control unit. The central actuating element is connected electronically to the control unit of the supply unit, so that control signals can be sent to the control unit from the central actuating element. The central actuator can, for example, as a door switch be formed, which is installed on the front door and / or the bathroom door of a hospital room. However, the central actuating element may, for example, also be an actuating element in a nursing room via which central actuation of the supply unit and / or all supply units in a region of a hospital is possible. The central actuating element is thus spatially removed from the supply unit and not optically perceptible connected directly to the supply unit. By means of the central actuating element, for example, the luminaire of the supply unit can be controlled such that it ensures general lighting, for example indirect room lighting with a predetermined intensity. The central actuating element can thus be used to predetermine which light source groups are activated by which light source unit. For example, night lighting can also be set by the central actuating element, ie an activation of lighting groups of a lighting unit can be ensured, which ensures a discreet illumination of a room. For example, the lamp can be completely switched off via the central actuating element. For example, an examination illumination can be activated via the central actuating element, in which a high illumination of the room is ensured by means of a plurality of the light sources.

In one embodiment, the control unit, the central actuator and the actuator are coordinated so that the central actuator generally outputs control signals to the actuator. This means that, via the actuation of the central actuating element, the control unit controls the light of the supply unit in accordance with the control signal of the central actuating element controls, wherein the set by the actuator device settings are overwritten. In a further exemplary embodiment, the central actuating element is designed so that the control signal set by the central actuating element can be reset by a further actuation of the central actuating element, after which the setting parameters of the luminaire previously set via the actuating device are set again. A corresponding prioritization of the central actuating element can bring about the advantage that, for example, night lighting or examination lighting can be centrally adjusted via the central actuating element, without the patient settings set via the actuating device being able to prevent this. A reset of the control signals of the central actuator by further actuation of the actuator can bring the advantage that after the end of a particular situation that requires a certain illumination of the patient environment, set the desired and previously set by the patient setting parameters of the lamp again are.

In a further embodiment, an interface to a nurse emergency call system is provided on the supply unit, wherein an emergency call button for triggering a nurse emergency call is provided on the supply unit. In this advantageous embodiment, the emergency call button is provided directly to the supply unit. Preferably, the interface to the nurse call system is integrated in the light, preferably in the actuator, so that a patient in the same actuator can find both the emergency call button and the controls to control the light. Preferably, one of the Operating elements of the actuating device designed as the emergency call button, wherein the emergency call button for outputting a control signal to the control unit for activating at least one of the lighting means of a light emitting unit formed as an emergency lighting unit of the lamp is formed. In this embodiment, the lamp comprises an emergency call center unit. By pressing the emergency call button, at least one light source of the emergency call light unit is activated. The described embodiment can bring several advantages: For example, such a light source of the emergency call light unit can be activated via the emergency call button of a specific actuating device that the light source above the patient bed lights from which the emergency call button was actuated. Hospital staff can thus immediately recognize when entering a patient room, from which bed the emergency call was made. For example, a further advantage may be that the patient can recognize that the emergency call light unit has been illuminated by the illuminator of the emergency call center unit, that he has made the nurse call and that he can count on hospital personnel.

Preferably, the supply unit comprises an interface for receiving a central reassurance signal transmitter, wherein the interface is designed such that a control signal can be output to the control unit for activating a luminous means of a luminous means unit designed as a soothing luminaire unit. This embodiment may, for example, bring with it the advantage that a patient can be indicated via the central reassurance signal generator and thus via the activation of a luminous means of the reassurance illuminant unit that hospital personnel are on their way to it is. In one embodiment, the tranquilizer unit and the emergency beacon unit may coincide. In one embodiment, one of these two lamp units, in one embodiment, both of these lamp units with another lamp unit, coincide, It can be activated via the emergency button a first light source group this common light unit, via the central reassurance signal a second light source group of the common light source unit. Thus, for example, the patient can recognize when he has made the nurse call and in turn recognize when the nurse call has been detected and staff is on the way to him. The feedback of a response to a nurse emergency call via a central tranquilizer can exert a particularly calming effect on a patient and prevent panic. The realization of the described control options via interfaces requires the professional realization of the interfaces and communication of the interfaces with the control unit, for example via a correspondingly designed bus.

Advantageously, the control unit is connected via a two-wire bus with the lamp units of the lamp. The two-wire bus can have a bus protocol that is adapted to the properties of the lamp, in particular to the number of lamp groups to be controlled and the lamp units to be driven. The two-wire bus can ensure a bidirectional communication between the lamp unit to be controlled or the lamp group and the control unit to be controlled. Known manner, a two-wire bus for a bidirectional control of multiple components with low susceptibility is particularly advantageous, as in the Present invention and the use of a control unit with an actuator with multiple controls and possibly other actuators and interfaces is the case.

Preferably, the supply unit has a converter, which is connected to the two-wire bus, wherein the converter for implementing the two-wire bus protocol is formed in a standard protocol and has an interface for connecting a lighting system that can be controlled via the standard protocol. For example, the converter can ensure conversion to a standard DALI protocol or standard KNX protocol or conversion to a 1-10V analog interface. The provision of the converter has the advantage that lighting systems, for example, for producing a general lighting in a patient room, but for example, simple lighting units can be controlled via a standard interface, so that the simple realization of the supply unit can be ensured with the corresponding connected lighting system. Preferably, at least one of the lighting unit of the supply unit is connected via the converter to the two-wire bus, wherein the converter for implementing the two-wire bus protocol is formed in a standard protocol. Thus, two different bus protocols are used in the supply unit according to the invention according to this embodiment. This can bring the advantage that for a lamp unit, a standard electronic ballast or a standard driver can be used, which can be controlled via a standard bus interface, wherein moreover the two-wire bus, the control unit with the lighting units connects to the conditions of the supply unit or to the Conditions of the light of the supply unit may be adjusted. The use of the converter ensures communication between a corresponding standard ECG ballast and the two-wire bus used in the supply unit.

In one embodiment, the supply unit has at least two control units, which are designed to control respectively different lights, wherein the control units are connected to each other via the two-wire bus. In this exemplary embodiment, a supply unit is designed such that at least two patient beds in a patient room can be supplied via the supply unit. Each patient bed is assigned a lamp. Each lamp is assigned a control unit. The fact that the control units are connected to each other via the two-wire bus, control signals can be exchanged between the control units, so that, for example, a central control of all control units of the supply unit is possible. The use of the control units via the two-wire bus can thus enable a homogeneous adjustment of the lighting in a patient room, for example via a central actuating element which controls both control units identically, for example via personal control elements and / or patient control elements of an actuating device, via the basic settings and / or a common circuit can be made for both lights. In one embodiment, each control unit and thus each lamp is associated with exactly one actuator. The actuating device has respective operating elements. For example, a patient can control the luminaire assigned to him from each bed. In one embodiment, both actuators Personnel controls on. It is possible that in one embodiment, the basic settings on both lights can be made simultaneously via the operator controls one of the actuators. It is possible in another embodiment that personnel controls of an actuator are only suitable for setting basic settings of the lamp, which is associated with the respective actuator.

Preferably, the central actuating element is connected to one of the control units, whereby a synchronization of the control units is ensured over the two-wire bus in such a way that the control units all receive the specifications of the control parameters of the central actuating element. This exemplary embodiment can bring about the advantage that all the control units are controlled via the central actuating element in such a way that their associated lamps have a radiation characteristic predetermined by the central actuating element. The prioritization between the central actuating element and the actuating device assigned to the respective control unit has already been explained above.

The supply unit preferably has a service operating element. The service control element can be realized for example via a remote control, which communicates with a corresponding wireless interface with the control unit of the supply unit. For example, an infrared remote control may be provided. For example, the service control element can also be connected or connectable to the control unit via a cable. The service control is suitable for making basic settings. For example, over the service control unit can be programmed to program the supply unit to a specific nurse emergency call system. For example, basic settings, such as the longitudinal section length of a region in which a certain lighting unit emits light, can be predeterminable. For example, further, explained above basic settings of the lights of the supply unit can be specified above.

The invention further relates to a system comprising at least two supply units, wherein the control units of the supply units are interconnected via the two-wire bus and together have the same central actuating element, wherein the central actuating element is connected to one of the control units of one of the supply units and via the two-wire bus synchronization ensures all control units of all supply units such that the control units all receive the specifications of the control parameters of the central actuator. As a result, it can be ensured that all supply units connected via the two-wire bus ensure, via their luminaires, a radiation characteristic which is predetermined via the central actuating element. This can be advantageous in particular when different care units are provided in a patient room and a uniform illumination of the patient room is desired.

In FIG. 1 a section of an embodiment of a supply unit 1 according to the invention is shown. In FIG. 1 the lighting fixture of the supply unit 1 is shown, which ensures a lighting function of the supply unit. Other components of the supply unit, such as connections etc. are in FIG. 1 not shown. The supply unit 1 has a housing 2, which is formed like a profile. In the housing 2, a space is provided in which supply lines can be arranged. The supply unit 1 has a light. Arranged on the housing 2 of the supply unit is a luminous means unit 4 of the luminaire of the supply unit 1, which comprises LEDs 3 as the luminous means. The lighting unit 4 is thus formed as an LED strip. The LEDs 3 are arranged side by side in the longitudinal direction. In each case only one LED 3 is provided in the transverse direction of the lighting unit 4. The LEDs 3 are uniform in the longitudinal direction spaced apart. The LEDs 3 each represent a light source group containing only one light source.

The light of the supply unit 1 has a control unit which in FIG. 1 not shown. The control unit controls the lighting unit 4 in such a way that a lighting section with the determined longitudinal section length d is always predetermined, within which the LEDs 3 of the lighting device 4 are activated by the control unit for emitting light. In this case, the control unit of the supply unit is designed such that the longitudinal position of the illumination section with the longitudinal section length d is variable in the longitudinal direction. In the illustrated embodiment, the control unit is designed so that the longitudinal section length of the illumination section can be predetermined in advance and that thereafter the longitudinal position of the illumination section is adjustable independently of the predetermined longitudinal section length. In the illustrated present embodiment, the illumination portion having the longitudinal portion length d is variable in its longitudinal position such that the illumination portion can be shifted from one longitudinal end to the other longitudinal end, maintaining the longitudinal portion length d respectively. The displacement of the illumination section is thus possible in steps corresponding to the distance between two LEDs 3.

In the FIG. 1 shown supply unit 1 also has LEDs 300, which are covered by a second light source unit 40, which acts as an emergency call center unit. While the LEDs 3 of the illuminant unit 4 are used for room lighting and / or reading illumination when the supply unit 1 is arranged in a room, the LEDs 300 are designed as signal LEDs which, when the supply unit is installed in a patient room are circuitry coupled with the nurse call of a patient. Each LED 300 forms a group of bulbs, which can be controlled separately and has only one light source. Depending on the setting, one or both of the LEDs 300 illuminate when a patient over whose bed the care unit 1 is placed calls one or both of the LEDs 300 so that the nurse can immediately identify which patient in the room made the nurse call. This embodiment has the advantage that the patient on the LED 300 recognizes the confirmation that he has made the nurse call, and thus can be reassured.

In a further advantageous embodiment, not shown, the second illuminant unit 40 of the luminaire has a further illuminant group with notification LEDs. Each one notification LED can be assigned to a respective LED 300. In one embodiment, only one notification LED is associated with all of the signal LEDs 300. The notification LED may be activated by a reassurance signaler connected to the control unit, which may be actuated by hospital personnel. The notification LED informs the patient who made the nurse call that hospital personnel are on their way to him.

The illuminant unit 4 and the second illuminant unit 40 comprising the LEDs 300 each have light-emitting groups which each comprise only a single LED 3 or 300. In other embodiments, at least one of the lamp groups may comprise a plurality of LEDs. Each group of lamps, and in the present embodiment so that each LED 3, 300 is independent of the remaining LEDs controllable. As a result, the longitudinal displacement of the lighting section is ensured. For example, the signal lights LEDs 300 may provide that each of the LEDs 300 is associated with a particular bed that is proximate to the LED 300 so that only the LED 300 illuminates from the proximity of which the nurse emergency call has been made. For example, circuit logic associated with the control unit may also be configured to light one or both LEDs 300, depending on the various types of nurse call, both LEDs 300 of the same patient or bed in the room where the care unit 1 is located is arranged, assigned.

In FIG. 2 is a schematic representation of a room with walls 8, 80 shown, in which two beds 6, 60, each with an associated side table 7, 70 are arranged. In the room, a supply unit 1 is arranged, which has two lights 9, 90. Each lamp is associated with a particular bed 6, 60 and each includes a control unit and an actuator and is controllable from the respective bed 6, 60 via the respective associated control unit. The control units are designed such that a lighting section 5, 50 can be predetermined with the specific longitudinal section length d within which the lighting means of the illuminating unit of the respective luminaire 9, 90 designed as a reading light are activated for emitting light. Also in the in FIG. 2 illustrated embodiment are provided as a light source LEDs. In the comparison between the FIGS. 2a and 2 B is the advantage of the embodiment of the supply unit 1 according to the invention can be seen. The illumination section 5, 50 is in each case set such that illumination via the luminaire above the respective associated bed 6, 60 is guaranteed. When changing over the beds 6, 60 and thus also the side tables 7, 70, a simple longitudinal displacement of the illumination section 5, 50 can be performed, while the illumination section 5, 50 each maintains its longitudinal section length d. This ensures a constant good illumination of the bed 6, 60 by the associated lighting section 5, 50. About the inventive design of the supply unit 1, the longitudinal displacement of the lighting section 5, 50 alone electronically, without the need for a specially designed mechanical coupling of the lights would be necessary to the housing of the supply unit 1.

In the Figures 3 and 4 in each case a supply unit 1 according to the invention is shown in cross-sectional view. In both embodiments, the supply unit 1 each have a housing 2, which is designed like a profile. In both embodiments, two different light emitting units are provided, each comprising LEDs as lighting means. The LEDs of the illuminant units are each as in FIG. 1 shown arranged in a row in the longitudinal direction next to each other. Therefore, in the cross-sectional illustration that in the Figures 3 and 4 Each of the exemplary embodiments is shown, in each case only one LED 10 of the first lamp unit and a LED 100 of the second lamp unit shown.

At the in FIG. 3 and 4 illustrated embodiments, the housing 2 of the supply unit 1 is mounted in each case on a wall 8. The LEDs 10 of the first lamp unit are arranged on a holding device 11 so that they emit light toward the ceiling. The holding device 11 is held on the housing 2 of the supply unit 1 via lateral webs. About the holding device 11 can be a certain angle of radiation, with which the LEDs 10 of the first Illuminant unit emit light into the room or to the ceiling, adjust. In addition, the supply unit 1 has a prismatic lens 12, which is assigned to the first lighting means unit and thus to the LEDs 10. Via the prismatic lens 12, a diffusion of the light emitted by the LEDs 10 light is achieved, so that a pleasant, uniform illumination of the ceiling is guaranteed.

In the embodiment according to FIG. 3 In addition, a reading light housing 103 is provided, which is arranged on the housing 2 of the supply unit 1, and within which a second light-emitting unit with LEDs 100 is arranged. The LEDs 100 are held in the reading light housing 103 via a holding device 101. About the holding device 101, the emission angle with which emit the LEDs 100 of the second lamp unit light, pretend. Since the distance of the LEDs 100 from the wall 8 is known, and thus the arrangement of the LEDs 100 to the arranged under the supply unit 1 bed of a patient, can be adjusted via the holding device 101, the emission direction of the LED 100 so that a reading area on the bed is lit. In addition, a prismatic lens 102 is arranged on the reading light housing 103, which influences the radiation characteristic of the light emitted by the LEDs 100 into the room. On the one hand, further influence can be exerted on the emission direction of the LEDs 100 in the space via the prismatic lens 102; on the other hand, with the prismatic lens 102, the light color and, if possible, glare-free illumination of the reading region can be adjusted by appropriate choice of the prismatic lens 102. In the embodiment according to FIG. 3 the reading light housing 103 is disposed half below and half in front of the housing 2 of the supply unit 1.

The embodiment according to FIG. 4 differs from the embodiment according to FIG. 3 by the different arrangement of the reading light housing 103 to the housing 2 of the supply unit 1. The reading light housing 103 extends in the embodiment according to FIG. 4 over the entire vertical length of the housing 2 of the supply unit 1. In addition, in the embodiment according to FIG. 4 the prismatic lens 102, which is associated with the LEDs 100 of the second lighting unit, designed differently, namely trough-shaped, so that the LEDs 100 can radiate light in a larger solid angle range in the room. In the embodiments according to FIG. 3 and FIG. 4 In each case, the reading light housing 103 and the holding device 101 are formed so that they are not transparent. Therefore, illumination of the room via the LEDs 100 can be done only via light beams that pass from the LEDs 100 through the prismatic lens 102 into the room. Accordingly, by selecting the prismatic lens 102, the illumination of the room can be adjusted by the LEDs 100 of the second lighting means 100.

In FIG. 5 is a schematic diagram of a circuit diagram for a supply unit 1 according to the invention shown schematically. The circuit diagram relates to the activation of the luminaire 200 of the supply unit 1 via an actuation device 201, a nurse emergency call system (in particular with integrated central reassurance signal generator) 202 and a central actuation element 203 by means of the control unit 20 which is assigned to the light 200 of the supply unit 1. The circuit sketch after FIG. 5 describes a circuit diagram associated with a particular luminaire 200 of the supply unit 1. In the supply unit 1, several lights can be provided. In addition, the in FIG. 5 shown circuit diagram with respect to a lamp 200 of a supply unit 1 are applied according to the invention, when the supply unit 1 is arranged together with other supply units in a patient room and as explained above to be synchronized with the other supply units.

The luminaire 200 is supplied with a potential-free supply voltage + Ub. The elements with which a control of the lamp 200 is feasible, namely the actuator 201, the nurse call system with integrated reassurance signal 202 and the external actuator 203 are electronically connected to the circuit of the lamp 200, in the described embodiment via an electrical line. The luminaire 200 has a luminous means unit 4 with the light-emitting means groups 31, 32, 33 and 34, a second light-emitting unit 40 with the light-emitting means groups 301, 302 as well as a third light-emitting unit 400 with the light-source group 3001. The light-emitting unit 4 is designed as a reading light and can furthermore fill out the function of an overview lighting. The illuminant unit 40 is designed as an emergency beacon unit. The lighting unit 400 is designed as a general lighting means. The lighting means of the lighting unit 400 are arranged on the ceiling facing the ceiling of the lamp 200 and provide an indirect illumination of the room.

The actuation device 201, the nurse call system 202 with integrated reassurance signal transmitter and the external actuation element 203 are designed to output control signals to the control unit 20. The control unit 20 communicates with the illuminant units 4, 40, 400 via a two-wire bus 500 Two-wire bus 500 is directly connected to the lamp units 4, 40, so that the Leuchtmitteinheiten 4, 40 provide an interface for the two-wire bus 500, which ensures control of the lamp groups 31, 32, 33, 34, 301, 302, the lighting unit 400 via a DALI gateway 501, ie, a converter that converts from the two-wire bus 500 to the DALI interface, as well as connected via a DALI interface standard ECG 502 to the control unit 20. This construction has the advantage that the protocol of the two-wire bus 500 can be designed such that a large number of light source groups of different light source units can be bidirectionally actuated, whereas for light source units, such as the light source units 400, which can only be controlled to a limited extent need be, a standard ballast can be used, which simplifies the design of the light 200 and reduced.

The illuminant unit 400 has only one illuminant group 3001. The lighting group 3001 comprises a plurality of LEDs, which are arranged as LED strips on the upper side of the luminaire 200. When switching on the general lighting, the light source group 3001 of the lighting unit 400 is activated, whereby an indirect lighting of the room is ensured. The activation of the light-emitting means group 3001 can take place via the external actuating device 201 and / or the central actuating element 203.

The actuating device 201 comprises as operating element, personal operating elements and patient operating elements. The controls are each designed as a button. The patient controls are provided on a handset that is connected to the handset for the nurse call system coincides while the personnel controls are provided on the housing of the supply unit 1 itself. The respective control elements are each assigned different control signals, which are explained in more detail below.

The central actuator 203 includes two buttons that are installable on the front door of a hospital room. The buttons are each assigned a different control signal. In other embodiments, further buttons may be provided with further control signals. In further embodiments, the buttons may also be duplicated, for example, be provided on the bathroom door and on the front door of a hospital room. The various control signals of the buttons of the external actuator will be explained in more detail below.

The nurse emergency call system 202 with integrated reassurance signal transmitter is integrated in the patient hand part of the actuating device in such a way that the nurse emergency call can be triggered via a button of the patient hand part. When the nurse emergency call is triggered, a control signal, which activates the lighting unit 301 of the lighting unit 40, is output to the control unit 20 via the same push-button. This allows the patient to recognize that he has made the nurse call. Via the nurse emergency call with integrated reassurance signal generator 202, a nurse can send a control signal to the control unit 20 after receiving the nurse emergency call via the external reassurance signal generator, so that the control unit 20 activates the illuminant group 302 of the illuminant unit 40. This allows the patient to recognize that the nurse call has been accepted and a nurse is on his way to him.

In further embodiments, which are not shown here, for example, two patient hand parts for different patient beds can be connected to the control unit 20 and each have a button for a nurse emergency call. The luminaire 200 can then be configured so that the illuminant unit 40 has two groups of lamps, the first of which is arranged in the vicinity of the first patient bed and the second in the vicinity of the second patient bed, wherein an activation of the nurse call by a button of a the bedside associated patient hand part, the control unit 20 receives a control signal to which the control unit 20 activates the light source group located in the vicinity of the bed from whose associated handset the nurse emergency call has been made. This embodiment may have the advantage that a nurse, upon entering the hospital room, can immediately recognize from which bed the nurse emergency call has been sent. The assignment of lighting group to handpiece can be carried out by setting the basic settings of the control unit.

The external actuator 203 has two buttons in the described embodiment. The first button is assigned a control signal, which activates the control unit 20 for activating the lamp group 3001 of the lamp unit 400. With this button, the general lighting can be switched on and off by briefly pressing in a patient room, by long pressing the examination illumination with activated groups of bulbs 31, 32, 33, 34, 3001. The second button of the external control 203 is when pressed by a short press such a control signal that an overview lighting of the light 200 is turned on, with a long press he controls the light "Central Off". The Overview lighting consists in that only one of the lamp groups 31, 32, 33, 34 of the lighting unit 4 is activated and emits light only with a pre-adjustable dimmed intensity. The overview lighting can be used, for example, as night lighting. The group of lamps which is activated via this second button of the external actuating element 203 can be set by means of the operating elements of the actuating device as well as the intensity of the emitted light. With the button of the external actuator 203, the overview lighting can only be switched on and off. It should be noted that the present embodiment is simplified. In practice, the lighting unit 4 usually comprises a much larger number of light-emitting groups. Personal control elements can be used to set the width of a light strip realized via activated light source groups and the intensity of the light strip, which is assigned to the overview light.

The patient controls of the actuator 201 have three buttons. With a first button, the reading light can be switched on and dimmed to a certain intensity by pressing several times. The setting of the reading light corresponds to the adjustment of the intensity of the light which is emitted by the lighting means groups 31, 32, 33, 34 of the lighting unit 4. The second button is used for switching and dimming the overview lighting. The overview lighting are assigned to certain lamp groups 31, 32, 33, 34 of the lighting unit 4. The intensity of the overview lighting can be set within a specified range by repeatedly pressing the button. The third button is assigned to the general lighting. About the button can be the Switch on the light source group 3001 of the lighting unit 400 and dim it by repeatedly pressing the button.

In addition, at least one personal control element is provided. In a particularly simple embodiment, the examination illumination can be switched on by simple actuation of the personal control element, wherein in the examination illumination the light source group 3001 of the light source unit 400 and a pre-adjustable number and selection of light source groups 31, 32, 33, 34 of the light source unit 4 radiate light with maximum intensity. In a simple exemplary embodiment, the investigation illumination is assigned all the groups of illuminants of the illuminant unit 4 and emits light of maximum intensity. In the simple embodiment with only one button as a personal control element, an adjustment of the position of the reading light can be done by pressing the button for at least three seconds. Then, the lamps of the groups of lamps 301 and 302 of the lamp unit 40 start to flash in order to signal to the operator that an adjustment of the position of the reading lamp is possible. The illuminant unit 40 can thus also be designed as an information illuminant unit for informing the operating personnel of the possibility of setting adjustment parameters of the luminaire 200. By pressing the button again, the position of the reading light can be moved. In the present embodiment, the width of the reading light is limited to two groups of lamps. By pressing the button can be selected, which are arranged next to each other arranged lighting groups of the lighting unit 4 as a reading light. As a result, the position of the reading light can be assigned to the position of the light 200 Beds are set. In other embodiments, further personal control elements may be provided, for example control elements for adjusting the intensity of the overview lighting and / or the general lighting, in particular for adjusting the illumination intensity and the lighting position of overview lighting and general lighting when the central operating element is actuated. In further embodiments, a remote control may be provided which communicates with the control unit 20 via a wireless interface. Using the remote control, lamp service personnel can adjust the basic settings of the luminaire 200. The basic settings can refer to the explained parameters, such as the intensity and position of the overview lighting.

The two-wire bus 500 of the luminaire 200 has an interface 600 with which the two-wire bus can be connected to a control unit of another luminaire. Via this interface 600, a synchronization of the control units different lights can be made, which for example via personal controls or external actuators uniform illumination of a room via synchronization of the control units can be guaranteed. Via the interface 600, the control unit of a supply unit can also be connected to a control unit of a further supply unit, so that several supply units can also be synchronized with one another. In any case, it may be advantageous for the external actuating element 203 to be connected to only one control unit of a luminaire of a supply unit arranged in a patient room, via this control unit and via the interface 600 of the Two-wire bus synchronization of all control units can be done. As a result, a particularly simple structure of different supply units, respectively different lights in a patient room is possible with which a synchronization of the lights, respectively the supply units, can be ensured to ensure a homogeneous illumination of a patient room.
