Description

lighting unit

Background of the invention

The present invention relates to a lighting unit, and more particularly to a retrofittable lighting unit.

The illumination unit according to the invention is suitable or designed in particular for retrofitting a carrying system or a supply console for medical end devices. Thus, the invention relates to retrofit lighting units for medical carrying systems and supply consoles.

Carrying systems and supply consoles for medical electrical equipment are frequently used in the clinical field, especially in hospitals (e.g., in operating theaters and intensive care units) and in medical practices. An existing problem in the medical care of patients is the provision of proper lighting that does not disturb the patient but still provides the personnel (i.e., the doctors and nurses) with sufficient light to do their job reasonably and conveniently.

Although ICU patients usually sleep in dormant rooms during the night, the doctors and nurses naturally continue their work. This includes observations on the medical equipment and on the patient himself. In operating rooms, too, dimmed light is sometimes used, for example, to make endoscopic examination radiation and / or examination images appear best during an operation. Since patient care does not always take place in a brightly lit environment, there is often a need for indirect medical practice or targeted light. The invention has for its object to meet this need with practical, flexible and tailored solutions.

FIG. 10 exploded view of the illumination unit shown in FIG. Description of the embodiments of the invention

1 shows an inventive carrying system T in the form of a ceiling stand for mounting in a medical treatment room (eg in an operating room or in an intensive care unit) in a hospital. The overhead tripod has a medical supply (e.g., power, gas, communication) supply console K of medical electrical (ME) terminals typically received and supported on one or more trays A. At the carrying system T three lighting units 10 according to the invention have been retrofitted. In other words, these lighting units 10 are designed for and in such a way that they are designed for retrofitting to carrying systems that are already mounted in hospitals or doctor's offices. The lighting units 10 can be easily attached and attached.

FIGS. 2 to 4 show a first exemplary embodiment of an illumination unit 10 according to the invention for indirect illumination of the room (in this case via ceiling lighting) in the darkened room in order to provide orientation, but without disturbing illumination in the area of activity.

In the first example, the lighting unit 10 is constructed such that it uses an electric power supply (mains current or rechargeable batteries) by a luminous element, an indirect illumination in the direction of the ceiling generated, with the aid of which, for example, in darkened operating rooms lighting is ensured for orientation. Two luminous bodies 2 are mounted on an elongated luminous body receptacle or an elongated luminaire frame 1 (for example by gluing, soldering, screwing, pinning, riveting). The luminous intensity of the luminous element 2 can be equipped with different numbers and arrangement of luminous elements depending on the required lighting conditions. In this example, the luminous bodies 2 consist of light-emitting diodes (LEDs), which are integrated in two flexible, roll-up strips. The strips have a width of about 8 mm and a thickness of about 1.5 mm and comprise 60 LEDs connected in two rows. The LEDs have a luminous intensity of 120 lumens, a beam angle of about 120 ° and a color locus of X 0.41, Y 0.42. The electrical supply of the filament 2 is ensured with a power supply (preferably 24 volts), which is mounted in or outside of the support system. The cover of the lamp frame 1 and 2 luminaires is carried out with an elongated and relatively flat (eg slightly curved) light cover 3. The cover 3 fulfills two tasks. The primary task is to reduce the luminous intensity to produce an indirect light. For this purpose, cloudy disks with different degrees of transmission or disks with applied lattice structure can be used for a scattering illumination. Alternatively, the brightness of the lighting unit can be regulated with a potentiometer. The luminaire cover 3 can be designed such that the luminaire frame 1 and the luminous bodies 2 are fixed in the cover 3 or their position can be determined with additional components. The attachment of the entire unit to the support system is effected by fastening means 4. As a fastening material are, for example, screws, pins, bolts, clips, adhesive or other constructive solutions for attachment.

Figures 5 to 7 show a second embodiment of an inventive, retrofittable lighting unit 10 for indirect lighting of the room (here as a floor lighting). This lighting unit 10 is on attached to a lower side of the supply console K and designed so that it is generated by using a power supply (mains or accumulators) by a plurality of lighting 2 indirect lighting in the direction of floor, with their help, for example, in a darkened operating room Lighting is ensured for orientation, but without disturbing lighting in the field of operation.

Basis of the retrofittable indirect lighting is the flat light frame or light fixture receptacle 1. The frame 1 can be used as a board or as a stocked with standard light-emitting elements 2 reflection strips (made of sheet metal, plastic, etc.). The luminosity of the lighting unit can be equipped with different numbers and arrangement of the luminous element 2 depending on the required lighting conditions. In this embodiment, the luminous bodies 2 (not visible in FIGS. 6 and 7) have a number in the range of 3 to 10 LEDs, which are attached to the lower side of the circuit board 1. Together, the LEDs have the following characteristics: luminous intensity of 225 lumens, color temperature of 5600 K, color rendering index of 80, and beam angle of about 120 °.

With the help of spacers 5, a distance between the luminous body 2 and the supply console K and between the luminous body 2 and the flat, round cover 3 is ensured in order to isolate these parts from the heat generated in the luminous body 2. As before, the cover 3 fulfills two tasks. The primary task is to reduce the luminous intensity to produce an indirect light. For this purpose, cloudy disks with different degrees of transmission or disks with applied lattice structure can be used for a scattering illumination. Alternatively, the brightness of the lighting unit can be regulated with a potentiometer. The attachment of the board 1 and the cover 3 to the supply bracket K is carried out with appropriate mounting material 4. The attachment can be done for example with screws, pins, bolts, adhesive or similar measures. Figures 8 to 10 show a third embodiment of a retrofit lighting unit 10 according to the invention for direct illumination of a tray or a device on the supply console K. A direct illumination of the immediate supply console environment (trays, ME devices, etc.) is thus achieved without disturbing lighting in the entire darkened room. The lighting unit 10 is designed so that it generates an internal or external electrical power supply (mains or batteries) by one or more lamp body 2 direct lighting, with the help of an illumination of attachments of the supply console K is ensured.

The frame or light housing 1 serves as the basis of the direct lighting unit 10. Its execution can be, for example, as an extruded profile made of plastic. In the luminaire housing 1, a reflection body 9 is mounted, the function of which is to receive the luminous bodies 2. The luminosity of the lighting unit 10 can be equipped with different numbers and arrangement of luminaires depending on the required lighting conditions.

The luminaire housing 1 is closed by a cover 3, which can optionally be inserted or fixed with fastening screws 4. The cover 3 again fulfills the two aforementioned tasks. The primary task is to reduce the luminosity to produce a direct light. For this purpose, it is possible to use opacified panes with different degrees of transmission or panes with applied lattice structure for a scattering illumination. Alternatively, the luminosity of the lighting unit 10 can be regulated with a potentiometer. The attachment means 4 comprise two clips or links 6 of the retrofit direct lighting and the supply console, and is designed to allow the indirect lighting unit to be mounted to the supply bracket with a "click." This attachment allows the user to retrofit the retrofittable lighting unit 10 in FIG to adjust or assemble different positions, eg the lighting Processing unit 10 is displaceable in directions V along the rod S and rotatable in directions R about a longitudinal axis of the rod. Thus, the user or the medical staff can change the orientation of the lighting by a manual manipulation (ie, by hand) as desired. The fastening material 7 serves to assemble or assemble the unit 10.

In this embodiment, the luminous bodies 2 comprise a number of a plurality of luminous elements (e.g., 72 LEDs) connected in series in two strips to produce a luminous intensity of 144 lumens. The beam angle is in this case again about 120 ° and the color locus X 0.29 Y 0.31. The power supply of the retrofittable direct lighting unit 10 is ensured with an electrical connection line 8, which can be made by means of plug-in coupling X on the supply console K. The ceiling and floor lighting units 10 of FIGS. 1-7 and the lighting unit 10 of FIGS. 8-10 can be provided with an electrical power supply in the form of rechargeable batteries (ie batteries) housed in the housing or on the frame 1 (for example under the covers 3) in addition to the luminous body 2) are arranged to be provided. Alternatively or additionally, each lighting unit 10 may comprise a mains power supply line which may be connected to the power supply of the carrying system T.

The purpose of the foregoing description is to illustrate the operation of preferred embodiments of the invention, and not to limit the scope of the invention. From the foregoing discussion, many variations will be apparent to those skilled in the art that are covered by the disclosure of the present invention.
