Description

The invention relates to a lighting module system and constructed from individual modules of the lighting module system lamp.

Luminaires equipped with energy-saving lamps require an operating module for operating the lamp, which can also be addressed as a ballast. The operating module is mains-voltage-fed and supplies the light source with the energy required for operation. The control of the light source via the operating module, such as a dimming. As a rule, such an operating module also has a bus interface so that it can be connected to an installation bus. If an operating module is operated via an installation bus, it can be controlled with the respective protocol used, for example in accordance with the DALI standard. Increasingly, LEDs are used as energy-saving lamps. The operating module supplies them with direct current. Since typically several LEDs are used in such a light source as light sources, the light source is addressed as a light source module in the context of this embodiment. To connect the lamp module to the operating module, the operating module has a module connector and the lamp module via a complementary mating connector.

DE 20 2011 050 974 U1 discloses an LED light tube which can be used as an exchange tube for a conventional fluorescent tube. It is emphasized that, for safe and long-term use of the tube, the individual LEDs should be connected in series at least eight in order to keep the voltage drop across the remaining LEDs as low as possible when burning through an LED. Furthermore, with respect to the problem of reverse polarity when installed in a conventional fluorescent tube holder, consisting of two mechanically uncoded pins, a rectifier is connected in the LED tube between the contact point and the LEDs, thereby ensuring that regardless of the electrical Contact the light tube lights up. An application of different lighting modules is not provided in the subject matter of this prior art.

WO 2012/086790 A1 describes a light module that is connected to an AC voltage. This light module comprises two different types of LEDs, the difference being in the color. The two types of LEDs are interconnected in opposite directions. Thus, different colors can be created by mixing. The mixture is carried out by a change in polarity of the AC voltage. Furthermore, this document discloses a protection circuit, based on the applied AC voltage which is carried out with the aid of Zener diodes.

In order to meet different requirements, different operating devices are used, especially when the lamp modules are designed multi-channel. Such a lighting module can be designed as a so-called Tunable White module. The illuminant module is then designed with two channels and has LEDs of different color temperatures in its two channels. By appropriate activation of the LEDs of one channel and that of the other channel, the desired color temperature with which the illuminant module is to shine can be adjusted by mixing a color component of one channel with that of the second channel. For controlling the two channels of such a lamp module, an operating module may be provided, which has in each case a driver for each channel. These drivers can be controlled independently of each other. According to another embodiment, two-channel lamp modules are driven by a common operating module operating according to a standard. This can be done, for example, with the DALI standard IEC 62386-209: 2011-06 (Part 209: Color / Color Temperature Control (Device Type 8)). While in the first variant with the use of two independent drivers, the two channels can be controlled independently of each other and the light at maximum power in each channel with 100%, a control of the individual channels takes place in an operating module, which operates according to the aforementioned specification, depending on the Actuation of the other channel, whereby the maximum luminous flux, which is delivered by the sum of the two channels is limited.

In order to prevent a lamp module designed for operation with a certain operating module from being inadvertently connected to another operating module, the different operating modules are equipped with mechanically differently designed connectors for connecting a luminaire module. Finally, it can happen in a wrong connection that the bulb is damaged or even destroyed. This can be associated with excessive heating, so that a risk to life and limb can not be excluded by an unnoticed wrong connection. However, equipping the operating devices and accordingly the lamp modules to be connected with different connectors is considered to be expensive, since this is not only to be considered in the interconnection of the modules, but also because one and the same lamp modules must be equipped with different connectors.

Based on this discussed prior art, the invention is therefore based on the object to propose a lighting module system and a lamp composed of individual modules of this lighting module system lamp, is avoided in the above-described disadvantage, but at the same time it is ensured that operation of a light source module, if not at the intended operating module connected and controlled by this, no dangerous operating conditions occur.

This object is achieved according to the invention by a lighting module system with at least two differently operating modules, each operating module for driving a differently designed lamp module, and with at least two differently controlled, to be operated with DC lamp modules which differently operating operating modules with mechanically same, but electrically different polarized connectors for connecting a so The light source module to be controlled are equipped and which lamp modules are equipped with the plug connectors of the operating modules mechanically engageable complementary connectors, the polarity of the electrical contacts of the input side connector of each lamp module for connecting it to an operating module according to the polarity of that operating module is provided with the This lamp module is to be controlled, and wherein each lamp module is equipped with a protection circuit for preventing damage or destruction of the same in a false-pole connection.

In this lighting module system, all modules are equipped with respect to their connection mechanism with one and the same connector, each two modules to be connected to each carry complementary connector (plug or socket). Thus, in this lighting module system to each operating module, regardless of its operation, each lamp module can be connected by engaging the corresponding complementary connectors. To code the interacting modules - operating module and lamp module - is turned off in this lighting module system to a different electrical polarity of the contacts of the connector. This means that, although a light emitting module which is not intended to operate with an operating module can be connected to it mechanically, the electrical contact between the operating module and the light bulb module is not intended in relation to the assignment of the electrical contacts.

According to one embodiment of the invention, a DC operation of the lamp modules is used to achieve such coding. While in the one operating module, a first electrical output contact the positive pole and the other electrical output contact represents the negative pole and are provided to operate with this operating device lamp modules with respect to the electrical contacts in their connectors for connecting the same poled to the operating device is the polarity of a different working equipment in the output contacts of the same vice versa. Accordingly, the input contacts in the connectors of the lamp modules to be operated with this operating device are also poled. In order to avoid damage or destruction of a lamp module in the case of a faulty connection, ie: connection of a lamp module to an operating device not intended for operation of this lamp module, each lamp module is equipped with a protective circuit. Such a protective circuit causes damage or even destruction of the lamp module or its light sources does not occur when this lamp module is connected in reverse pole to the operating device and is controlled by this. It is understood that in multi-channel lamp modules each channel has such a protection circuit. By such a protective circuit, a by-pass is formed to the light sources of this channel in order to pass the current introduced into this channel as lossless as possible to the light sources. If the illuminant modules are those which have LEDs as light sources, such a protective circuit can be realized in a simple and cost-effective manner by means of a freewheeling diode. For other light sources, one will typically provide other protection circuits adapted to the respective light sources.

In a preferred embodiment it is provided that when connecting a lamp module to a not provided for this operating module - ie: For example, in a false pole connection - provided that in a control this lamp module by the operating device, the lamp module outputs a Falschpolungssignal. Typically, this is an optical signal. In a particularly easy to implement embodiment is a non-illumination of the lamp module in a control by the non-intended operating device, the false-polarity signal. It is also quite possible that other optical polarity reversal signals are provided by such a luminous module in the case of a connection which is not intended, such as, for example, the illumination of a color-different individual LED, for example red color, a flashing of the light sources. It is also conceivable that such a lamp module emits an acoustic Falschpolungssignal.

A special feature of this lighting module system is that the already known from the prior art, different operating devices must not be changed, but that only the module connector is adapted. Above all, a connection without tools is possible and due to the connector also subsequently changed without further notice. Therefore, this lighting module system concept is above all also suitable for the realization of rail system luminaires and / or light bands. For such applications, it is advantageous if each light-emitting module next to an input-side connector for connecting the lamp module to an operating device also has an output side connector having the same polarity of its electrical contacts as the output side connector of the operating module. In this way, several or even a plurality of lamp modules can be connected in series. In this case, the light modules connected in series need not be identical. The only requirement is that these are designed so that they can be controlled by the same type of operating equipment. In this respect, the term used in the context of this embodiment of the connection of a lamp module to an operating device includes both the immediate connection of the same to an operating device and the indirect connection of the same to an operating device with the interposition of one or more other lighting modules or other modules.

If several light sources modules are to be connected in series, it is possible to arrange them spatially separated from each other and then insert an extension piece between two electrically connected in series light source modules. Such an extension piece carries at its two ends respectively complementary connector, one in the output side connector of a first lamp module and the other connector fits into the input side connector of the subsequent lamp module. The polarity is not changed between the input-side connector and the output-side connector in a channel in such an extension piece.

In a two- or multi-channel operating device, it is possible that a channel turner is switched on between two light sources. In a dual-channel operating device with such a channel turner the input side first channel output side to the second channel and the input side second channel output side placed on the first channel. In this way, for example, monochrome lamp modules, which are equipped with light sources in only one channel, can be controlled differently in the segment in front of and behind such a channel turner.

In order to ensure operation of a light-emitting module, if this has an output-side connector for connecting further light-emitting modules, it can be provided to design the output-side connector such that without the complementary connector of a subsequent light-emitting module, a channel turner or an extension piece is inserted therein, the plus - And the minus pole are contacted with each other. When plugging in the complementary connector for connecting a subsequent lamp module or another module of this short circuit is interrupted and the individual lines connected to those of the subsequent module. In another embodiment, it is provided that a short-circuit plug is inserted into the output-side connector of the last light-emitting module, through which then the two poles of each channel are electrically combined.

In order to minimize the number of possible faulty connections of light-emitting modules to control gear not intended for these, it is provided in an expedient development that operating devices and associated light-emitting module additionally carry the same color coding. Such a color coding can be realized for example by a uniform coloring of the mutually engageable connector. It is understood that such a color coding can also be made elsewhere on or on the operating device and on or on the luminaire module.

In a further development, it is provided that at least one of the two operating modules is designed so that it can operate in two different power levels. Such an operating module is thus designed, for example, to provide an operating current of 350 mA in one power stage and, for example, of 700 mA in the other operating stage. An encoding of these two different operating levels via the polarity of the electrical contacts of the output side connector of this operating module. In one polarity variant, an operating current is provided in one power stage and in the reverse polarity variant in the other power stage. In this way, you can be controlled by your performance forth different light sources with such a control gear. Due to the above-described Verpolungsschutzes possible damage is counteracted in a wrong polarity connection.

Quite possible is also an embodiment of a lighting module system in which each operating module is designed to be able to provide operating current in two different power levels.

An illumination module system in the illustrated embodiment comprises two different operating modules B ₁ , B ₂ . The two operating modules B ₁ , B _{2 shown by} way of example are both designed with two channels and are provided, for example, for driving light- emitting modules whose color temperature can be set, in which light- emitting module modules can be so-called tunable white light- emitting modules . The operating module B ₁ comprises two individual drivers D ₁ , D ₂ , each driver D ₁ , D _{2 being} responsible for the control of a channel independently of the other driver D ₂ or D ₁ . The operating device B ₁ has a power supply not shown in detail and a DALI interface. The operating module B ₁ also has a module connector S ₁ , to which a lamp module can be connected. The operating module B ₁ and also the operating module B ₂ are used to drive LED lighting modules, ie such light-emitting modules, which are operated with direct current. In the operation module B ₁ , the outputs in the two channels are as off FIG. 1 Obviously electrically coded.

The operating module B ₂ is one which operates according to the DALI standard IEC 62386-209: 2011-06 (Part 209: Color / Color Temperature Control (Device Type 8)). This operating module has a single driver D ₃ , via which both channels are controlled. Otherwise, the operating module B ₂ is constructed in the same way as the operating module B ₁ and has a mains connection and a DALI interface. For electrical coding of this operating module B ₂ , the two lines of each channel are reversed poled as the polarity in the operating device B _first The connector S _{2 of} the operating module B ₂ is with the exception of the above polarity identical to the connector S _{1 of} the operating module B _1st This means that all the lighting modules of the lighting module system can be connected both to the operating module B ₁ and to the operating module B ₂ .

The illumination module system includes three different light source modules L ₁ , L ₂ , L ₃ . The lamp module L ₁ is designed to be operated with the operating module B ₁ . The lamp module L ₁ has a number of LEDs in each channel. These are connected in series, as is the rule for LED bulbs. In addition to the LEDs, the luminous means module L ₁ for each channel comprises a protective circuit 1, 1.1, which is designed in the illustrated embodiment in each case as a freewheeling diode. The free-wheeling diode bridges the number of LEDs in each channel and is connected in the opposite direction to the forward or reverse direction of the LEDs. This achieves this that, in the case of a false-pole connection of the luminary module L ₁ and, if the blocking voltage of the LEDs is exceeded, the current in the reverse polarity case flows through the freewheeling diode of the protective circuit 1 and / or 1.1 and thus on the LED array. In this way, the LEDs are safely protected in case of polarity reversal from destruction or damage. Due to the freewheeling diode, the current is passed without loss of the LED array of each channel.

The lamp module L ₁ has an input-side connector S _E whose electrical contacts are poled as well as the electrical contacts in the output-side connector S _{1 of} the operating module B _first In addition to the input-side connector S _E , the lamp module L ₁ also has an output-side connector S _A. The output-side connector S _A is the same structure as the connector S _{1 of} the operating module B ₁ , which also includes the electrical polarity. It is understood that the input-side connector S _{E of} the lamp module L _{1 is constructed to be} complementary to the output-side connectors S ₁ , S _A. Typically, the output connectors S ₁ , S _{A are designed} as a socket and the input-side connector S _E as a plug. The LED array in each channel of the lamp module L ₁ is for issuing a different color temperature. By different activation of the channels or the LEDs installed therein, thus the emitted light temperature can be adjusted. In the illustrated embodiment, the illuminant module L ₁ is a tunable white illuminant module.

In addition to the light source module L ₁ , the lighting module system comprises a light source module L ₂ , which is designed to be operated with the operating module B ₂ . The different polarity of the output-side connector S _{2 of} the operating module B ₂ according to the LEDs are arranged in this lamp module L ₂ in the reverse flow direction. The same applies to the freewheeling diode of the respective protective circuit 2, 2.1. Also, the lamp module L ₂ is equipped with an input-side connector S _E and an output-side connector S _A. Incidentally, the luminous means module L ₂ is constructed in the same way as the luminous means module L ₁ .

The illumination module system comprises in the illustrated embodiment, a further light source module L _3rd This is designed as a monochrome lamp module and therefore includes an LED array in only one channel. Accordingly, only this channel is a protection circuit associated, as this is already described in relation to the lamp module L ₁ . The other channel is only through-connected by the input-side connector S _E to the output-side connector S _A.

The polarity of the channels of the operating devices B ₁ , B ₂ and the lamp modules L ₁ , L ₂ , L ₃ are in FIG. 1 indicated.

In addition to the above-described modules B ₁ , B ₂ , L ₁ , L ₂ , L ₃ , the lighting module system also has shorting plug 3. Such a shorting plug 3 is plugged onto the output side connector S _{A of} a lamp module L ₁ or L ₂ , which in one possible Series of series-connected lamp modules L ₁ and L ₂ of the last lamp module is inserted. With such a short-circuit plug 3, the plus line is connected to the minus line in each channel.

Furthermore, the lighting module system has extension pieces 4. The extension pieces 4 also carry input-side connectors S _E and output-side connectors S _A. The extension pieces 4 are used to connect two not directly connected to each other lamp modules. The extension pieces 4 can be used for both types, irrespective of the operating module provided for a specific lighting route.

A channel turner 5 is also associated with the lighting module system. The channel turner 5 has an input-side connector S _E and an output-side connector S _A. The channel turner 5 can be used, for example, in a luminaire track that is operated with the operating device B ₁ . Through the channel turner 5, which is switched on between two light source modules L ₁ , there is a change of the channel, but not the polarity. Thus, in the channel turner 5, the first channel received in the input side connector S _{E is set} to the second channel in the output side connector S _A and the input side second channel is output to the first channel of the output side connector S _A.

With these modules, of which a plurality or a plurality of each module is typically available, different lights can be realized.

FIG. 2 shows the interconnection of individual modules from the lighting module system of FIG. 1 , As operating module, the operating module B _{1 is} used in this example. The operating module B ₁ is used to drive the lamp modules L ₁ . Consequently, a lighting module L _{1 is} connected to the operating module B ₁ . Although it was intended at the lamp module ₁ L another illuminant module to connect L _1, is connected to the light source module ₁ of L FIG. 2 a light source module L _{2 has been} connected, by Eingeingstellen the input side connector S _{E of} the lamp module L ₂ with the output side connector S _{A of} the lamp module L _first To the light source module L ₂ is another in turn, a lamp module L ₁ connected. The light path formed in this way is completed by a shorting plug 3 on the output side connector S _{A of} the last light source module L ₁ .

If the operating module B _{1 is} turned on, the light source module L ₂ does not light up. This is in the illustrated embodiment, a false polarity signal and thereby signals a fitter that he accidentally not a light-emitting module L ₁ , but a light source module L _{2 has} mounted and connected. Due to the protective circuit 2, 2.1 with their respective freewheeling diode, the lamp module L _{2 takes} no damage. Due to the freewheeling diode current flow is not interrupted, which is why the two separated by the light source module L ₂ lamp modules L ₁ lit according to purpose. The improperly built-in light source module L ₂ can be easily replaced by a light source module L ₁ or it is the distance between the two lamp modules L ₁ bridged by an extension piece 4. Such an embodiment is in FIG. 3 shown.

The two channels in each light source module L ₁ , which are each designed as tunable white light module, can be controlled independently by the operating module B ₁ by the two drivers D ₁ , D ₂ .

In addition to forming a light path with monochrome light source modules L ₃ , which are controlled by a channel of the operating module B ₁ , it is also possible to combine two-channel designed light source modules L ₁ with single-channel working light source modules L ₃ . This is exemplary in FIG. 4 shown, wherein the two lamp modules L ₁ , L ₃ are electrically connected to each other by an extension piece 4.

With the operating module B ₁ and the two independently controllable drivers D ₁ , D ₂ , the single-channel lamp modules L ₃ with both channels and thus, as in FIG. 5 shown alternately controlled in series. For this purpose serves the Channel turner 5, which is turned on in such a case between the two lamp modules L ₃ . The first channel of the operating module B ₁ , for which the driver D _{1 is} responsible, is placed by means of the channel turner 5 on the second channel at the input of the second lamp module L ₃ . Accordingly, the channel controlled by the driver D ₂ second channel is placed by the channel turner on the first channel in its output-side connector S _A.

It is understood that multiple channel turner can also be used within a luminaire route. In this way, a free assignment of the lamp modules L ₃ to the two channels can be made.

FIG. 6 shows a further lighting route, this time the operating module B ₂ is used. If a luminous flux module L _{1 is} switched on in the luminaire path, this can be detected in the same way as when the luminous flux module L _{2 is switched on} in the luminous path of the luminous element FIG. 1 , operated with the operating module B ₁ , is set forth.

FIG. 6 shows a luminaire path with two lamp modules L ₂ , connected to an operating module B _2nd At the end of the luminaire section sits a shorting plug 3.

The invention has been described with reference to embodiments. Without departing from the scope of the applicable claims, numerous further embodiments for a person skilled in the art will be able to implement the invention.
