Description

Leuchtensvstem

The present invention relates to a lighting system comprising a lamp unit, a light-carrying rail for fixing the lamp unit and a unit for transmitting data and / or light to the lamp unit (s). More specifically, the present invention relates to a lighting system comprising a lamp unit, a light-up support rail for fixing the lamp unit, and a communication unit for connecting the lamp system to a communication network, the data being to be transmitted from the communication network to the lamp unit (s). Alternatively, the invention relates to a lighting system, which has a lighting unit, a light support rail for fixing the lamp unit and a coupling unit, wherein light from the coupling unit to the lamp unit (s) to be transmitted.

The networking of sensors, devices, machines and everyday objects is often associated with the connection of the devices involved in modern communication networks, such as the Internet. Such networked systems are increasingly gaining in importance. The resulting "Internet of Things" (IOT) also poses new challenges to lighting systems, such as when data transmission through a lighting system is to be provided or when the users of the lighting system are expected to increase it through the lighting system Functionality and flexibility in designing the lighting system is achieved.

In order to accomplish the increase in functionality, it becomes necessary to provide a plurality of individual electronic units. These electronic units are often distributed throughout the entire lighting system and require a connection to the data and / or power supply.

Lighting systems are already known from the prior art, which allow a connection and linking of lighting units to an external data infrastructure by means of cable connection. The data infrastructure is provided, for example, by floor distributors in buildings. For example, the TECTON system developed by the applicant may be mentioned here. In this case, a busbar is provided in which, in addition to the power supply for the luminaire units mounted in the busbar, also data lines for data communication are provided, wherein the data communication is based for example on the DALI protocol. However, in order to connect a plurality of individual lamp units to the communication network, it becomes necessary to connect each of the light units contained in the bus bar to the communication network. This increases not only the number of cables required but also the number of connections required to the data infrastructure. Similarly, the number of terminals and cables for the power supply increases.

This is a great challenge, especially with larger lighting systems in the industrial or commercial area (eg airport buildings or office buildings). It is also important to "hide" this multitude of cables in order to preserve an aesthetically pleasing result of the lighting system the freedom of design of the lighting system limited because, for example, certain arrangements of the individual lighting units are not possible.

In addition, the connection of remote lighting units is difficult, since the transmission range of data lines is limited. This can vary depending on the type of communication network used for individual types of cable, usually from lengths of up to a few loom. It should be noted, however, that with increasing cable length under certain circumstances, the quality of the data signal to be transmitted is impaired and problems due to electromagnetic incompatibility may occur. Although such problems can be addressed by improved shielding of the cables, this increases the cost of each cable. In addition, the tapping of the signal lines to the individual lamp unit requires additional design measures to overcome, for example, a higher contact resistance of the cable to the contact terminal of the lamp unit. The solution of the aforementioned problems is particularly difficult if in addition even higher data transmission rates are to be achieved in the lighting system.

Similar problems can also be found in the power supply of components (eg a lighting unit), which are distributed over long distances. Due to the sometimes relatively long (up to a few loom) cable lengths, problems arise with regard to the electromagnetic compatibility. Especially in buildings with increased sensitivity to such phenomena, such as laboratories or hospitals, this leads to problems in the applicability of such lighting systems. If elevated temperatures also occur in the area to be illuminated, the lines and electronic components are subject to thermal influences which adversely affect their reliability and failure rate. It is therefore an object of the present invention to provide a lighting system that allows connection of the lighting units to a data infrastructure while providing high data rates. At the same time a high degree of flexibility in the arrangement and design of the lighting units in the lighting system and an improved aesthetically pleasing result should be achieved.

It is a further object of the present invention to provide a lighting system that provides connection of the lighting units to a wireless power supply network. At the same time a high degree of flexibility in the arrangement and design of the lighting units in the lighting system and an improved aesthetically pleasing result should be achieved.

These objects are achieved by the subject matter of the independent claims. The dependent claims further form the central idea of the present invention in a particularly advantageous manner.

According to a first aspect, the present invention relates to a lighting system which has a lighting unit and a light support rail to which the lighting unit is attached. Furthermore, the lighting system has a communication unit for connecting the lighting system to a communication network for receiving data from the communication network.

According to the invention, a "communication network" is understood as meaning a connection of a plurality of computing devices for exchanging data, whereby according to the invention the term "data" is understood to mean information represented by a physical signal. Furthermore, a "data infrastructure" is understood to mean devices which are required for the control, control and transfer of data. <br/><br/> The communication unit according to the invention furthermore serves for coupling in an optical signal based on the data received from the communication network (ie in particular light and preferably laser light). Furthermore, the luminaire system according to the invention has a decoupling element for transmitting at least part of the received data from the optical signal to the luminaire unit The luminaire system can preferably also have a plurality of luminaire units, which are all attached to the luminous support rail and wherein each luminaire unit is at least a decoupling element is assigned. The lighting system according to the invention makes it possible to connect individual lighting units to a communication network. The use of the communication unit for coupling the data received from the communication network in the form of an optical signal makes it possible to dispense entirely with cable connections for data transmission in the light carrier rail. This makes it possible to connect a large number of light units simultaneously via the communication unit with the communication network and at the same time maintain individual control and control of the individual lighting unit, which can be effected inter alia by means of the decoupling element. In addition, the lighting units can be distributed over greater distances, whereby the lighting system can be designed more freely. In this case, in contrast to a transmission solution with cable connections, problems caused by electromagnetic incompatibility avoided and an additional shielding of the lighting system is not required. The quality of the data signal transmitted to the lamp units can thus be increased. At the same time, high data transmission rates between the communication unit and the lamp unit are achieved by the optical transmission. This makes it possible by the light system according to the invention, which can handle, for example, in IOT applications often considerable amounts of data better. Also, so-called "LiFi" (English Light Fidelity - based on the wireless network "WiFi") applications for the construction of wireless communication networks by the inventive light system can be made possible. By using a light guide rail, the light units can be flexibly arranged in the light system and easy to install. At the same time, a continuous and covered transmission path of the optical signal within the light guide rail is ensured by the light guide rail. The light guide rail can be formed in any way; For example, one or more parts, consisting of separate components arranged distributed or contiguous or integrally formed, etc. For example, the light guide rail, a planar element, such as a ceiling and in particular an intermediate ceiling, and / or a profile element, such as a profile support have. The communication unit of the lighting system may further preferably have a communication interface for connecting the lighting system to a communication network, which may be provided in particular as a wired or wireless interface such as a Bluetooth module. The received data from the communication network may further be associated with an analog or digital signal in a preferred embodiment. Preferably The received data may also correspond to an electrical, optical and / or machine-readable signal.

This makes it possible to connect different communication networks to the lighting system, so that a high flexibility of the lighting system with regard to its applicability for different types of buildings (eg. Airport or hospitals) is generated. Furthermore, the openness of the communication interface makes it possible to connect a multiplicity of different terminals to the lighting system.

According to a preferred embodiment of the invention, the communication unit has a conversion device which is set up to generate the optical signal based on the data received from the communication network and to couple it into the light carrier rail. In this case, the conversion device may preferably be provided in an edge region of the light carrier rail, preferably on an end face of a particular elongated light carrier rail. This makes it easy to couple an optical signal in the light guide rail. The provision of the conversion device in an edge region of the light guide rail simplifies the connection of the communication unit to wired networks and an external power supply. In addition, this mounting location allows maximum utilization of the light guide rail for data transmission and attachment of lighting units.

Furthermore, according to the invention, the optical signal can be composed of signals having a different frequency, wherein preferably a (single) frequency is assigned to a respective lighting unit.

This makes it possible to assign different information to an optical signal of a specific frequency and thus make it distinguishable. This effect can then be used, for example, by the decoupling unit of the lighting system, by decoupling only the relevant components from the optical signal.

According to a preferred embodiment of the invention, the light guide rail can be designed in several parts. Furthermore, the light guide rail can be elongated, bent and / or angled in its extension direction. In addition, the light guide rail particularly preferably has at least one flat side, which is used for mounting the light guide rail, wherein the flat side is preferably formed by a connecting support connecting two legs of a U-shaped light support rail is. For this purpose, the light carrier rail preferably has a U-shaped cross section; is thus formed as a U-profile.

By providing a flat side of the light guide rail, it is possible to allow easy installation of the light guide rail on a designated mounting surface, such as the ceiling of a room. With a multi-part designed light guide rail almost any configurations and lengths of the lighting system can be generated. The U-shape of the cross section of the light guide rail makes it possible to hide power supply lines and operating devices within the light guide rail and thus to achieve an aesthetically pleasing result. Furthermore, it can be handled freely, for example, by a fitter within the light guide rail, since the light guide rail is open to one side. Likewise, the open side offers a simple mounting option of the lighting units on / in the light guide rail.

According to a preferred embodiment of the invention, the light guide rail on elongated and preferably rectilinearly extending areas, which serve as a data channel for transmitting the optical signal and in which preferably only the decoupling elements protrude. In addition, the light carrier rail preferably has areas for supplying the lighting units, which are preferably formed by supply lines, in particular a through-wiring. These areas are also preferably opposite the elongate areas of the data channel and further preferably parallel to them.

As a result, a higher flexibility in the arrangement and distribution of the lamp units can be generated on the light support rail, since all the lighting units have access to the necessary power supply and required for data transmission optical signal. A defined distribution of the respective channels within the cross section of the light guide rail not only reduces the risk of errors in the assembly, but also the complexity of the components during the manufacturing process.

According to a preferred embodiment of the invention, the decoupling element protrudes at least into a path of the optical signal emitted by the communication unit in the luminous support rail, in particular into the data channel of the luminous support rail. In this case, the decoupling element preferably has a decoupling section in order to provide at least part of the optical signal, preferably from the data channel for the luminaire unit, and particularly preferably to divert it to the luminaire unit. The outcoupling section may be a semipermeable mirror, such as a dichroic mirror. Thus, a selective selection of the signal to be transmitted to the lamp unit signal is possible, which may be present for example as an optical or electrical signal. The selection of the portion of the optical signal to be deflected may be dependent on the frequency or wavelength of the incoming optical signal. This makes it possible, inter alia, to transmit to the lamp unit either the data transmitted by the communication network to the lighting system as a whole, or only a part of this data selected by the coupling-out element.

The decoupling element preferably further comprises a detector unit for detecting the optical signal and converting it into an electrical signal, wherein the aforementioned optical signal is preferably the entire deflected optical signal or the deflected part of the optical signal. If the detector unit is arranged in the path of the optical signal and in particular the data channel, it can be provided as a coupling-out section in the sense of the invention.

Thus, it becomes possible to integrate the evaluation and deflection of the incident on the coupling element optical signal in a single component and to transmit to the lamp unit only an electrical signal. This makes it possible, for example, to also use lighting units that are not equipped with a detector unit, which can simplify maintenance and repair. In addition, other components that can only receive an electrical control signal can be integrated into the lighting system.

The decoupling element further preferably has deflection sections, in order to deliver the deflected optical signal or the deflected part of the optical signal, preferably after detection by means of the detector unit, back into the illuminating support rail, in particular the data channel, and particularly preferably to supply the optical signal. This makes it possible for the decoupling element to evaluate and manipulate the incoming optical signal before other lighting units can receive the optical signal. The decoupling element could thus, for example, still additional information that it receives, for example, from another sensor element, coupled into the optical signal and forward it to other lighting units. According to a preferred embodiment of the invention, at least part of the decoupling element, preferably at least the detector unit, is provided integrally with the luminaire unit. This is preferably provided integrally with the lamp unit in such a way that, when the lamp unit is fastened to the light guide rail, the coupling-out element, preferably at least the coupling-out section, in the Light support rail is arranged. In this case, the decoupling element is preferably arranged in a path of the optical signal emitted by the communication unit in the illuminating support rail, such as preferably the data channel.

This makes it possible to provide on the lamp unit no electrical connections with the decoupling section. Furthermore, the decoupling sections of the respective lamp unit are already in one of the data channels and can thus ensure a correct deflection of the optical signal to the lamp unit.

Furthermore, the lighting unit can have a coupling section, which has means for electrically contacting the lighting unit, for example with a supply line such as through-wiring, and also provides means for mechanically fastening the lighting unit in the light support rail, in particular on corresponding fastening means of the light support rail, and / or additionally comprising at least a part of the decoupling element. For this purpose, the light guide rail preferably has corresponding corresponding fastening means, which are furthermore preferably formed integrally with the light guide rail.

The fact that the decoupling elements are arranged on the lamp units, no special precautions are necessary in the light guide rail itself to allow at certain positions the decoupling of the optical signal by the lamp unit. That is, the lamp units can be optionally positioned within the light guide rail. This not only reduces the cost of connecting the lamp units to the communication network, but also extends the flexibility in terms of the possibilities for arranging the lamp units.

The lamp unit can furthermore preferably have an electrical or electronic unit. Particularly preferred is a lamp into consideration, which has a corresponding light source such as an LED. Alternatively or additionally, however, it is also conceivable that the lamp unit is designed as a sensor, motor or control device or the like. In principle, any electrical or electronic unit comes into consideration, which can usually be found in lighting systems and is preferred to control. This makes it possible to expand the lighting system almost arbitrarily by electrical or electronic units and to integrate additional components, such as a sensor, an electrical adjusting device or a camera to fulfill other functions in the lighting system. According to a preferred embodiment of the invention, the lamp unit can be connected via cables to the decoupling element, in particular to the detector unit, for transmitting an electrical signal having at least a portion of the received data based on the optical signal. Preferably, the electrical signal may also be based on the deflected optical signal or only the deflected part of the optical signal. Of course, alternatively or additionally, a connection by means of an optical signal (for example, by deflection described above) conceivable.

Thus, it becomes possible to integrate the evaluation and deflection of the incident on the coupling element optical signal in a single component and to transmit to the lamp unit only an electrical signal. This makes it possible to use, for example, lighting units that are not equipped with a detector unit, which can simplify maintenance and repair. In addition, other components that can only receive an electrical control signal can be integrated into the lighting system. According to a preferred embodiment of the invention, the lamp unit can be releasably attached to the light guide rail. This can preferably be provided such that an outcoupling element integrally provided with the lamp unit is positioned when the lamp unit is fastened to pick up the optical signal in the light carrier rail and particularly preferably in the data channel. This makes it possible to easily maintain the lighting system and provide lighting units quickly and easily and exchange.

The communication unit may further comprise a coupling unit for coupling light as the optical signal into the light guide rail.

This makes it possible to couple light with defined properties in the light guide rail and so make it usable as a disk.

The present invention further relates, according to a second aspect, to a lighting system comprising a lighting unit and a lighting support rail to which the lighting unit is attached. The lighting system further comprises a coupling unit for coupling light into the light guide rail and a decoupling element for transmitting at least a portion of the coupled light to the lamp unit.

According to the invention, a "coupling unit for coupling light" basically means any lighting device, in particular a device, with the light in particular a predetermined property such as a defined orientation in the light guide rail is dispensed. The given property of the light may, for example, also be understood to mean the composition of the light, for example with respect to its frequency components and their amplitudes.

Of course, this lighting system may also preferably have a plurality of lamp units, which are all attached to the light guide rail and wherein each lamp unit is associated with at least one output element.

The luminaire system according to the invention makes it possible to supply individual luminaire units with defined light in order to provide light, data, energy or other light-transmitted properties to the luminaire units thereon. With the aforementioned system, it is also possible to operate the lighting system without providing cables. This makes it possible to provide a large number of light units individually via the coupling unit with light individually. In addition, the lighting units can be distributed over greater distances, whereby the lighting system can be designed more freely. In this case, in contrast to a transmission solution with cable connections, problems caused by electromagnetic incompatibility avoided and an additional shielding of the lighting system is not required. By using a light guide rail, the light units can be flexibly arranged in the light system and easy to install. At the same time, a continuous and covered transmission path of the optical signal within the light guide rail is ensured by the light guide rail. The light guide rail can be formed in any way; For example, one or more parts, consisting of separate components arranged distributed or contiguous or integrally formed, etc. For example, the light guide rail, a planar element, such as a ceiling and in particular an intermediate ceiling, and / or a profile element, such as a profile support have.

The coupling unit can be designed for the defined and preferably directional coupling of light into the light carrier rail. In the context of the invention, "defined coupling" is understood as meaning a defined emission region, as can be achieved by a luminous means itself or, for example, also by a defined optical system The coupling unit thus particularly preferably has a laser, such as a power laser, for coupling the light into the light carrier rail, so that light can be introduced into the system in a targeted manner and thus also effectively utilized, for example, via the outcoupling elements , The two alternative aspects of the present invention may also be combined in any manner. Thus, the lighting system according to the second aspect of the invention may further comprise a communication unit for connecting the lighting system to a communication network for receiving data from the communication network and for driving the coupling unit based on the received data and / or for coupling in a data received from the communication network having optical signal based in the light carrier rail, wherein the optical signal is preferably composed of signals having a different frequency, wherein furthermore preferably a frequency is assigned to each one lighting unit. The advantages have already been explained and in the present case arise in the same way.

In a preferred embodiment, the communication unit may have the coupling unit for coupling the light and / or the optical signal based on the data received from the communication network as the coupled light into the light guide rail. This is especially true when using a laser. In this way, a powerful system can be provided in a particularly compact manner.

The communication unit of all embodiments may be provided in the same way. Thus, the communication unit may have a communication interface for connecting the lighting system to a communication network, in particular a wired or wireless interface such as a Bluetooth module. The received data can be assigned from the communication network to an analog or digital signal, preferably an electrical, optical and / or machine-readable signal. The communication unit may have a conversion device that is configured to generate the optical signal based on the data received from the communication network and to couple it into the light carrier rail, wherein the conversion device is preferably provided in an edge region of the light carrier rail, particularly preferably on an end side in particular an elongated light support rail. The advantages have already been explained and in the present case arise in the same way. According to the lighting system of all the embodiments, the lamp unit may include lighting means such as an LED for emitting light for the purpose of lighting and / or data communication by means of or based on the optical signal. The lighting means are preferably designed to emit an optical signal, for example the optical signal based on the data received from the communication network. The lighting unit can thus either for easy light output in particular in the visible range (ie for illumination purposes) as well as for data transmission and thus preferably for control purposes, for example, by light emission of an optical signal in the non-visible region.

According to a preferred embodiment, the luminaire unit can have a remote phosphor layer as light source for emitting light on the basis of the light and / or optical signal transmitted by the decoupling element. In that the lamp unit has a remote phosphor layer, light generated centrally in the coupling unit can be used decentrally in the lamp units for emitting light. By decoupling the coupled into the system light in any way and preferably adjustable (eg. For adjusting the power of the decoupling or the proportion of fanning the light) can be tapped. In addition, further components for influencing the light, such as, for example, optics for defined light emission, can be provided in the luminaire unit itself. Thus, the light generation can be done, for example, by means of laser energy centrally at the beginning of the lighting system, while the light conversion takes place by means of remote phosphor locally in the lighting units. This leads to an improved thermal of the system by dividing the two heat generation points on the one hand and light conversion on the other. Thus, e.g. better high temperature applications in higher temperature environments (eg industry) and also generally better light quality (eg for museum, retail, etc.) due to more stable color shift over the lifetime, because the temperature influence of the lamp unit is lower.

The lighting system of all embodiments may further comprise a control unit for controlling the amount of the part of the received data and / or the coupled light transmitted by the coupling-out element to the lighting unit. Incidentally, the control unit may be designed in such a way as to also control or regulate all other components of the system and its components which may be of controllable design, such as, for example, the lighting unit.

The lamp unit of all embodiments may include solar cells for converting stray light emitted into the lamp unit into electrical energy. Thus, the efficiency of the lighting system can be further increased.

The lamp unit of all embodiments may include an electrical or electronic unit. This may be, for example, a lamp with a light source such as an LED, a sensor, a motor such as a servomotor, a control device, a camera, networking modules, data devices, wireless transmission units such as a Bluetooth beacon, an emergency lighting unit and act like that. The possibilities of such units are extensive and not limited by the present invention. The lighting system can thus be varied and used. For example, an emergency lighting can be provided in such a way that a small "mini-laser" is provided which, for example, is fed by the energy of a storage unit in the event of a failure of the lighting system The light of the "mini-laser" can then be converted, for example, into a remote phosphor layer be coupled and thus provide emergency lighting.

The lighting system of all embodiments, in particular the lighting unit or the decoupling element, may further comprise a conversion unit for partially or completely converting at least a part of the coupled-in light or the part of the light transferred from the decoupling element into electrical energy. The conversion unit can be provided, for example, as a solar cell, photodiode or the like. Thus, the light energy of the coupled-in light can preferably be used for integrated applications, such as the operation of the lighting units or a part thereof, such as electrical or electronic units. For example, sensors, Bluetooth beacons, cameras, networking components such as radio links and data devices, LIFI components can be easily supplied with energy, since they often have only a small electrical power. In addition, an additional unit could be installed, for example, for on-off switching, dimming or color change in the lamp unit, which takes over the control of the lamp unit.

The luminaire unit of all embodiments can furthermore have a receiving unit for receiving light, preferably a part of the coupled-in light and / or optical signal which is not transmitted to the luminaire unit. The receiving unit may have an absorber unit for receiving the light energy and / or a detector unit for detecting the light energy and / or a deflection unit for re-coupling at least a part of the light into the light guide rail. Thus, the efficiency of the lighting system can be further increased.

The lighting system of all embodiments may further include a storage unit for storing the energy of the portion of the coupled light transmitted through the extraction element to the lighting unit. For this purpose, the storage unit can have, for example, a capacitor and / or accumulator. The stored energy in the storage unit can be particularly preferably provided for the electrical or electronic units of the (corresponding) lighting unit. The storage unit may particularly preferably comprise the absorber unit. The efficiency of the lighting system can thus be further increased. In addition, even when the lamp unit is switched off electrical energy, for example, be provided for basic control functions or other electrical units such as sensors that must work even when turned off.

It has already been mentioned that the light guide rail of all embodiments can be designed as desired and, for example, can be designed as a flat element, such as a ceiling (for example false ceiling), and / or a profile element (for example profile support). The light support rail can be made in several parts. It may be elongated, bent and / or angled in its direction of extension. In particular, as a profile element, the light guide rail may have a U-shaped cross-section. The light support rail may have at least one planar side, which is used for mounting the light support rail, wherein the flat side may preferably be formed by a connecting member connecting two legs of a U-shaped light support rail. The light carrier rail can have elongate and preferably rectilinearly extending regions which serve as a channel, in particular as a data channel for transmitting the optical signal and / or in particular as a light channel for transmitting the light of the coupling unit, and into which only the outcoupling elements can protrude. The light guide rail may have areas for supplying the lamp units, which are preferably formed by supply lines, in particular a through-wiring, these areas preferably opposite the elongated areas of the data channel and / or light channel and further preferably parallel to these. The embodiments of the light guide rail are diverse and not limited by the present invention. The lighting system can therefore be adjusted as desired and individually to the desired technical, spatial and optical conditions and wishes. The coupling-out element can protrude at least into a path of the light coupled in by the coupling-in unit in the light guide rail, in particular in the light channel of the light guide rail. The decoupling element can have a decoupling section in order to provide at least a part of the coupled-in light preferably from the light channel for the luminaire unit and particularly preferably to deflect the luminaire unit. The coupling-out section may be a semitransparent mirror, such as a dichroic mirror.

Thus, a defined or selective transmission of the light to be transmitted to the lamp unit is made possible, which can be used for example for the provision of electrical energy and / or for light delivery purposes, in particular lighting or data transmission purposes (eg. For LIFI application). The selection the part of the light to be deflected may be made depending on the desired use thereof. Thus, for example, the light unit as a whole or only one selected by the decoupling member of the same can be transmitted to the lamp unit. The decoupling element may comprise a detector unit for detecting the coupled-in light, preferably the deflected light or the deflected part of the light, and converting it into an electrical signal. If the detector unit is arranged in the path of the coupled-in light and in particular the light channel, it can be provided as an outcoupling section in the sense of the invention. Thus, it becomes possible to integrate the deflection and conversion of the light striking the decoupling element in a single component and to transmit to the lamp unit only an electrical signal or the electrical energy. This makes it possible, for example, to also use lighting units that are not equipped with a detector unit, which can simplify maintenance and repair. In addition, other components that can only receive an electrical control signal can be integrated into the lighting system.

The decoupling element may further comprise deflection sections in order to return the deflected light or the deflected part of the light, preferably after detection by means of the detector unit or partial conversion by means of the conversion unit, back into the light support rail, in particular the light channel, and more preferably to the coupled-in light. Thus, the overall efficiency of the lighting system can be increased.

At least part of the decoupling element, preferably at least the detector unit or other components, such as the conversion unit, may be integrally provided with the luminaire unit. This preferably so that when mounting the lamp unit to the light support rail, the decoupling element, preferably at least the decoupling, is arranged in the Leuchtentragschiene, in particular in a path of the emitted by the communication unit optical signal in the light support rail, as preferably the data channel, and / or in particular in a path of the coupled by the coupling unit light in the light guide rail, as preferably the light channel. As a result, the assembly of the lamp unit and the correct placement of the decoupling element, for example, in the light channel is simplified.

The lamp unit may further comprise a coupling portion, which means for electrically contacting the lamp unit, for example with a supply line as a through-wiring, means for mechanically fixing the lamp unit in the light guide rail, in particular on corresponding fastening means of the light support rail, and / or at least a part of the decoupling element. The advantages of this embodiment have already been explained and arise here in the same

Wise.

The luminaire unit can be detachably fastened to the luminous support rail, preferably in such a way that an outcoupling element integrally provided with the luminaire unit is preferably fixed in the data channel and / or for picking up the light in the luminous support rail when the luminaire unit is attached to the optical signal in the luminous support rail Light channel is positioned. This makes it possible to easily maintain the lighting system and provide lighting units quickly and easily and exchange.

Unless otherwise stated, the features described in this application refer to all embodiments. Incidentally, all the features of the embodiments and the following embodiments can be combined and exchanged with one another in any desired manner.

For this purpose, the lighting system 100 has an illuminating support rail 700 which is preferably elongated in its extension direction and to which at least one luminaire unit 200 is preferably detachably fastened. However, the light guide rail 700 may also have a curved in the direction of extension or angled course or else be composed of differently shaped sections. As can be seen in FIG. 1, the light carrier rail 700 preferably has at least one flat side on which the light carrier rail 700 can be fastened to a mounting surface 900. In this case, the planar side is preferably formed by a connection carrier connecting a two limbs of a U-shaped light carrier rail. The light support rail 700 can therefore be provided as a profile element, such as a profile support. However, it is also conceivable that the light support rail 700 is formed overall as a planar element; So it essentially extends in one plane. As such a flat element, for example, a flat-shaped support or a ceiling, such as a suspended ceiling or false ceiling serve. The thus provided cavity between the false ceiling as light support rail 700 and ceiling of the room can thus serve to accommodate the lighting system or a part thereof. Through the false ceiling, the light system is protected to the outside provided so that appropriate protective provisions (eg. Laser protection regulations) can be met.

The mounting surface 900 may include any flat surfaces, such as a wall or ceiling of a room or a hall in a building, but there are also mounting plates for pendant lights for such attachment conceivable. These can also be provided as light carrier rail 700. Also, the light guide rail 700 can be received as a mounting system in an opening in the mounting surface 900 and secured. The attachment means of the light support rail 700 to the mounting surface 900 are arbitrary, including conceivable, for example, screw or clip connections. Furthermore, it is also conceivable that the light guide rail 700 is executed in several parts. In this case, particularly long and preferably rectilinear lighting systems 100 can be provided. Alternatively or additionally, angled and arbitrarily curved profiles in a plan view of the mounted on the mounting surface 900 light guide rail 700 are conceivable. Further, according to the embodiment, the light guide rail 700 preferably has a cross section opened to one side, whereby the mounting can be simplified. Particularly preferred, as shown in Figures 4 and 5, the provision of a U-shaped cross-section. However, other cross sections of the light guide rail 700 are conceivable. In each case, it can be seen in the two illustrations that the light carrier rail 700 is not only set up to mechanically receive the lamp unit 200, but also to provide the electrical supply to the lamp unit 200.

For this purpose, the light guide rail 700 particularly preferably in one of the two side walls areas for supplying the lamp unit 200, in which electrical supply lines 302 are provided. The supply lines 302 are preferably formed as through-wiring, so that a power supply along the entire light-emitting rail 700 can be provided. From the supply lines 302, the lighting unit 200 can be supplied with electrical energy by means of electrical leads 303, for example in the form of cables or stable tapping elements (eg contact hooks or contact contacts). This electrical energy is provided, for example, by means of connection to the power supply 800 (see FIGS. 1 and 8).

As can also be seen from FIGS. 4, 5 and 9, the light carrier rail 700 preferably has further regions extending along the extension direction of the light carrier rail 700, which regions can serve as a channel, in particular as a data channel 301 for transmitting an optical signal emitted by a communication unit 500 (following more detailed explanations) and / or as a light channel 301 'for transmitting light emitted by a coupling unit 503 or coupled into the light carrier rail (to follow more detailed explanations). In order to ensure a successful transmission of an optical signal or light from the transmitter source to a receiver, therefore, no components should protrude into the data channel 301 or light channel 301 ', which blocks the path of the optical signal or light channel 301' To obstruct light. In the two exemplary embodiments according to FIG. 4 and FIG. 5, the supply lines 302 extending along the extension direction of the light carrier rail 700 lie opposite the elongate region of the data channel 301 (FIG. 4) or the data channels 301 (FIG. 5) and / or the light channel 301 '. the light channels 301 '(see Figure 9) and more preferably run parallel to these.

The light guide rail 700 may preferably be made of metal, in particular aluminum, or plastic in cutting manufacturing processes or casting processes (continuous casting, injection molding, etc.), but this can be adapted to the requirements of the components according to any. In the case of a light support rail 700 as a false ceiling this is preferably made of customary for false ceilings materials.

The lighting system 100 according to the present invention further comprises a unit for transmitting data and / or light to the lamp unit (s) 200 in addition to the lamp unit 200 and the lamp support rail 700 for mounting the lamp unit 200.

For this purpose, the lighting system 100 further has, according to one aspect of the invention, a communication unit 500 for connecting the lighting system 100 to a communication network (not shown). Data is received from the communication network via the communication unit 500 and coupled into the light carrier rail 700 as an optical signal based on the data received from the communication network. This optical signal is also referred to below as "coupled-in optical signal." According to another aspect of the invention, the lighting system 100 alternatively has a coupling-in unit 503 for coupling light into the illuminating support rail 700. This light will also be referred to below as "coupled-in light " designated.

According to a preferred embodiment, it is also conceivable that the two aspects of the present invention are present together in the lighting system 100, as for example in Figure 9 is shown. This, for example, in parallel, so complementary. However, it is also conceivable for the communication unit 500 to have the coupling-in unit 503 for coupling in the light and / or light as the optical signal or the optical signal based on the data received from the communication network as the coupled-in light into the illuminating support rail 700. the coupling unit 503 is associated with such a communication unit 500, as shown by way of example in Figures 1, 6 and 8.

As shown in FIGS. 1 and 6, the communication unit 500 preferably has a communication interface 501 for connecting the lighting system 100 to a communication network. For this purpose, in particular wired or wireless interfaces, such as a WIFI module or a Bluetooth module, can be provided as interfaces. The lighting system 100 can thus be connected via the communication interface 501 by means of a cable or a radio module to a communication network. In this case, the communication interface 501 of the lighting system 100 can be adapted to any communication networks, for example to the (lighting management) communication network of the building. Such communication networks can follow, for example, standardized data protocols (for example Bluetooth, TCP / IP, bus systems, DALI or CAT5). However, it is also quite generally possible with networks in which information is present as an analog or optical signal, for example by means of transmission via optical waveguides. The received data from the communication network are thus an analog or digital signal, but preferably an electrical, optical and / or machine-readable signal assignable. Furthermore, the remote control (remote application) of the lighting system 100 can also be made very generally via the communication interface 501. Furthermore, it is also conceivable that the communication unit 500 can take over functions of a network participant as master or slave in the communication network.

The communication unit 500 further preferably has a conversion device 502, which is set up to generate an optical signal based on the data received from the communication network and to couple this into the light carrier rail 700.

Thus, for example, in the case that an electrical signal is connected to the communication unit 500, a conversion of an electrical Signals take place to an optical signal. Likewise, if, for example, an optical signal is connected to the communication unit 500 by means of an optical waveguide, the optical signal is either merely forwarded or adapted to the form required for further processing in the lighting system 100.

As can be seen from FIG. 1, the conversion device 502 is preferably located in an edge region of the light carrier rail 700 and is particularly preferably provided on an end face of the light carrier rail 700. According to an embodiment, the conversion device 502 may be a laser, in particular a frequency laser. Any other source is conceivable, by means of which an optical signal can be delivered; For example, any light source by means of which an optical signal in the form of light can be delivered. Preferably, therefore, the optical signal is provided or coupled in the form of light.

The optical signal coupled in by the conversion device 502 is preferably composed of signals of different frequency. Particularly preferably, a (defined) frequency is assigned to one of the lighting units 200 in each case. This makes it possible inter alia to selectively provide and transmit information that is only relevant to a single or a group of lighting units 200. For example, information is transmitted to a first lamp unit 200 at a first frequency fi only, while a second and third lamp unit 200 receives information by means of the injected optical signal at a second frequency f2. In addition, however, it is also conceivable for a lighting unit 200 to be assigned a plurality of frequencies which may contain different or identical information. This makes it possible, for example, to control a lighting unit 200 several times during a data transmission cycle.

Furthermore, however, it is also conceivable not only to vary the composition of the frequencies contained in the coupled-in signal, but likewise to provide, for example, a variation of the amplitude by means of a carrier wave and thus to transmit the received data to the lamp units 200. The coupling-in unit 503 can be designed for the defined and preferably directional coupling of light into the light carrier rail 700. For this purpose, the coupling-in unit 700 can also have a laser and preferably a power laser, wherein any other light source is conceivable with which a defined or directed light emission is possible. The lighting system 100 also has a decoupling element 400. According to the first aspect, the lighting system 100 comprises a decoupling element 400 for transmitting at least a portion of the received data from the coupled optical signal to the lamp unit 200. According to the second aspect, the lighting system 100 comprises a decoupling element 400 for transmitting at least a portion of the coupled light to the Luminaire unit 200 on. These can also be combined when both aspects are realized in a lighting system 100. If the optical signal is in the form of light, the decoupling element 400 serves to transmit at least a portion of the received data to the lamp unit 200 by means of at least a portion of the coupled-in light.

For this purpose, the decoupling element 400 preferably has a decoupling section 420 in order to provide at least part of the coupled-in optical signal or at least part of the coupled-in light to the luminaire unit 200 and preferably to deflect it to the luminaire unit. The decoupling section 420 may, for example, be designed as a semitransparent mirror, such as a dichroic mirror. However, the decoupling section 420 can also be provided quite generally as a frequency mirror, which has a similar functionality to a fiber Bragg grating. With the decoupling section 420, it is possible to provide only certain parts of the signal or light impinging on the luminaire unit 200, and in particular to let it through, or to reflect or deflect it completely or partially. The determination of which part of the signal or light is provided or reflected / deflected, for example, depending on the wavelength or frequency of the incident signal or light.

The operation of the decoupling element 400 is well illustrated, for example, in Figures 1, 6 and 8 and more clearly in Figures 2 and 7. In the exemplary embodiment, the coupled-in optical signal or light 610 impinges on a first outcoupling section 420, whereby a part of the coupled-in optical signal or light 610 is coupled out as a first coupled-out signal or first part of the light 611. The remaining part of the coupled-in optical signal or light 610 passes through the first coupling-out section 420 as remaining optical signal or remaining light 620 and then impinges on a second coupling-out section 420 in which a second coupled-out signal or second part of the light 621 is coupled out and is diverted. The remaining part 630 of the remaining optical signal or light 620 indicated in FIGS. 1, 6 and 8 may, for example, strike other luminaire units 200 (not shown). It is also possible that the remaining optical signal or light 620 is completely decoupled and thus no remaining part 630 remains. Generally, moreover It should be noted that the decoupling element 400 can also pass the impinging signal unchanged.

The lighting system 100 can, as shown in FIG. 6, furthermore have a receiving unit 1000 for receiving light, preferably a part of the coupled-in light and / or optical signal which is not transmitted to the lighting unit 200, that is to say the remaining part 630. The receiving unit 1000 can for this purpose have an absorber unit 1100 for receiving the light energy in order to effectively absorb excess energy. The energy thus absorbed can be used further if necessary; For example, be stored as electrical energy for the light system 100. The absorber unit 1000 can also have a detector unit for detecting the light energy. The value thus detected can, for example, be fed back 1001 to the communication unit 500 in order to be available there for controlling the lighting system 100. For example, the power of a laser can be adjusted as a conversion device 502 or a coupling-in unit 503 on the basis of the feedback 1001. The absorber unit 1000 can also have a deflecting unit for re-coupling at least a part of the light into the illuminating support rail 700.

For this purpose, the decoupling element 400 protrudes, preferably at least partially, into a path of the optical signal emitted by the communication unit 500 in the illuminating support rail 700 or into a path of the light coupled into the illuminating support rail 700 by the coupling-in unit 503. This is apparent in particular from Figures 1, 2 and 6 to 8 and 4, 5 and 9. Particularly preferably, the path of the optical signal emitted by the communication unit 500 in the light carrier rail 700 extends within a data channel 301, so that the outcoupling element 400 preferably projects exclusively into the data channel 301 and preferably diverts a part of the optical signal to the lamp unit 200. Equally, the path of the light coupled in by the coupling-in unit 503 in the light-emitting slide rail 700 preferably extends within a light channel 301 ', so that the coupling-out element 400 preferably projects exclusively into the data channel 301 or light channel 301' and preferably a part of the optical signal or Light to the lamp unit 200 deflects. This can be seen for example in Figures 4, 5 and 9 well. Thus, preferably also the outcoupling element 400 protrudes into the data channel 301 or light channel 301 'of the light carrier rail 700.

With reference to the embodiment of FIG. 7, the lighting system 100 may further include a conversion unit 1200 for partially or completely converting at least a portion of the coupled light or output from the extraction element 400 transmitted portion of the light into electrical energy. This electrical energy can then be provided for electrical or electronic units of the lighting system 100 or the lighting unit 200, which are specified in greater detail below by way of example. The lighting system 100 may further include a storage unit 1300 for storing the electric power of the portion of the coupled light transmitted through the extraction element 400 to the lamp unit 200. The memory unit 1300 may have a capacitor and / or accumulator. The energy stored in the storage unit 1300 may thus be preferably provided at any time for the electrical or electronic units. According to a preferred embodiment, the absorber unit 1100 may include the storage unit 1300 to store the energy received by the absorber unit.

As can be seen particularly advantageously from FIGS. 1 and 2 as well as 6, 8 and 9, the decoupling element 400 furthermore has a detector unit 410 for detecting the optical signal or coupled-in light. Preferably, this optical signal is the deflected, coupled-in optical signal or a deflected part of the optical signal striking the outcoupling section 420. Particularly preferably, this coupled-in light is the deflected light or a deflected part of the light striking the decoupling section 420. The detector unit 410 thereby ensures a conversion of the incident on this optical signal or light into an electrical signal.

It should be noted in particular that according to the invention, the transmission of at least part of the received data from the coupled-in optical signal to the lamp unit 200 can be made optionally as a transmission of an optical signal or of light or as transmission of an electrical signal.

In the exemplary embodiment illustrated in FIGS. 1, 2 and 8, the first 611 and the second decoupled signal 621 each impinge on a detector unit 410 which is attached to a corresponding lamp unit 200. In the case of the embodiment of FIG. 6 this applies to the optical signal 621. In this case, therefore, an optical transmission of at least part of the received data from the coupled-in optical signal or light to the lamp unit 200 takes place. In contrast, the embodiments illustrated in FIGS. 3 to 5 and 9 show an electrical transmission of at least part of the received data from the coupled-in optical signal to the lamp unit 200 by means of data lines 201 provided for this purpose. In this case the detector unit 410 is preferably located in the path of the coupled-in optical signal or light 610 and in particular in or close to the data channel 301 or light channel 301 '.

Furthermore, it is also conceivable that the decoupling element 400 preferably has deflection sections 421 in order to dispense the deflected optical signal or light or the diverted part of the optical signal or light back into the light carrier rail 700 in order to provide it, for example, to further lighting units 200. This is shown by way of example in FIG.

In this case, the deflected optical signal 611 may be detected by the sensor 411 of the detector unit 410, for example, first. These sensor values are then output to the luminaire unit 200 by means of data lines 201, where they are preferably evaluated. It is also conceivable to release the optical signal 611 immediately after detection and unchanged and to couple it into the light guide rail 700 again by means of the deflection sections 421. Alternatively, however, it is also conceivable that an additional transmission unit 412 mounted in the detector unit 410 is used to output new information in the form of the optical signal 612 to the light carrier rail 700 and to forward it to other lamp units. This new information is transmitted to the transmitting unit 412 according to the embodiment shown in Figure 3, for example, coming from the lamp unit 200 data lines 202.

In the case where the reproduced optical signal 611 is not changed by this reproduction, but amplified only in its amplitude, the decoupling element 400 can also be regarded as a signal repeater. In addition, in the case where, for example, no frequency-dependent deflection takes place at the coupling-out section 420, it should further be noted that the detector unit 410 should be adapted to filter out the information relevant to the respective lighting unit 200 from the signal. Accordingly, the transmitting unit 412 should preferably also be set up to emit the emitted optical signal 612 in the format of the optical signal which is readable for other detector units 410. The same applies to the embodiments for coupling light, in particular light as an optical signal, which also preferably after detection by means of the detector unit 410 or at least partial conversion by means of the conversion unit, back into the light support rail 700 and in particular the Light channel 310 'is discharged and particularly preferably fed back to the coupled light.

The returned optical signals or the returned light are preferably fed back by the transmitting unit 412 into the data channel 301 or light channel 301 'and are particularly preferably fed to the optical signal or light.

The lighting unit 200 of the lighting system 100 may have one or more electrical or electronic units. This can be, for example, a luminaire with a luminous means, such as a LED 2002 (see FIG. Alternatively or additionally, the electrical or electronic units can also be sensors, motors such as a servomotor or control or computing devices, cameras, networking modules, data devices, wireless transmission units such as a Bluetooth beacon, emergency lighting units and the like. In the figures 1 to 9, the lamp unit 200 is therefore shown in its most general form and not specified. FIG. 10 schematically shows a possible design of a luminaire unit 200. For example, the luminaire unit 200 may have an LED module 2002, which is also preferably provided in a luminaire housing 2003, possibly with further luminaire electronics (eg driver). The LED module 2002 here is further associated with an optic 2004 in the luminaire housing 2003 in order to emit the light emitted by the LED module 2002 for defined light emission (illumination). Furthermore, it is conceivable to be able to carry out additional functions, such as, for example, an analysis of sensor data or provision of a wireless network for the building, by providing a computing unit in the lighting unit 200.

The light sources 2002 of the light unit 200 are preferably used for the light output for illumination and / or for data communication by means of or based on the optical signal. The light-emitting means 2002 are therefore preferably designed for emitting an optical signal, particularly preferably the optical signal based on the data received from the communication network. This can be generated in the luminaire unit after detection of the optical signal and emitted via the luminous means 2002, for example in the non-visible region. However, it is also conceivable that the coupled in the form of light optical signal is provided by the decoupling element 400 directly for delivery via the lamp unit.

The luminaire unit 200 can furthermore have a remote phosphor layer as light source for emitting light on the basis of the light and / or optical signal transmitted by the outcoupling element 400. Thus, as shown in Figures 6 and 7, in the Light support rail 700 coupled light can be transmitted by means of the Auskoppelemente 400 on the lamp unit 200 by it is, for example. Simply deflected to the respective lamp unit 200. It may preferably be directed directly to the remote phosphor layer, where a desired light conversion takes place. When using a laser, the short-wave light stimulates the phosphor layer and thus generates the desired light on site in the lamp unit 200. By the spatial separation of light generation in the communication unit 500 and the coupling unit 503 and light conversion in the lamp unit 200 can be divided by dividing these two Heat points the thermal of the lighting system 100 can be improved overall. The lighting system 100 may further include a control unit 1400 for controlling 1440 the amount of the portion of the received data and / or the injected light transmitted by the coupling-out element 400 to the lighting unit 200. The control unit 1400 may also be provided to control other components of the lighting system 100, such as the electrical or electronic unit. In this case, the control unit 1400 can be provided decentrally, for example in the outcoupling element 400 or the lighting unit 200, as shown in FIG. 7, or also centrally.

Moreover, as shown in FIG. 10, the lamp unit 200 may have solar cells 2000 for converting stray light 2001 emitted into the lamp unit 200 into electrical energy. Thus, the overall efficiency of the lighting system 100 is increased. The lamp unit 200 is preferably detachably attached to the light guide rail 700. This preferably so that a decoupling element 400 integrally provided with the luminaire unit 200 when attaching the luminaire unit 200 for tapping the optical signal in the luminous support rail 700, preferably in the data channel 301 and / or for tapping the light in the luminous support rail 700, preferably in the light channel 301 '. is positioned.

Preferably, the lighting system 100 may also include a plurality of lamp units 200, which are all attached to the light guide rail 700. It is particularly preferred, as shown for example in Figures 1, 6 and 8, each lamp unit 200 associated with at least one coupling-out element 400. The coupling-out element 400 can, as already mentioned, preferably be provided at least partially integrally with the lighting unit 200. When mounting the lamp unit 200 in the light guide rail 700, the outcoupling element 400 is preferably automatically positioned in the light guide rail 700 and protrudes preferably in the data channel 301 or light channel 301 'inside. This can be seen for example in Figures 1 and 2 and 6 to 8.

Figures 1 and 2 show a preferred embodiment of the lamp unit 200, in which at least a part of the coupling-out element is provided integrally with the lamp unit 200. In this case, the lighting unit 200 has at least the detector unit 410. When fastening the lamp unit 200 to the light guide rail 700 so that the coupling-out element 400 is arranged in the light guide rail 700. As can be seen from FIGS. 1 and 2, in the illustrated preferred embodiment at least the coupling-out section 420 projects into the path of the optical signal 610 emitted by the communication unit 500 or into the path of the light 610 coupled in by the coupling-in unit 503 within the light guide rail 700. wherein the path of the optical signal or light preferably corresponds to a data channel 301 or light channel 301 'in the light carrier rail 700.

The mounting of the lighting system 100 can be further simplified in that the lighting unit 200 preferably has a coupling section (not shown) which on the one hand provides means for electrical contacting of the lighting unit 200, such as taps to the supply lines shown in FIGS. 4 and 5 302. On the other hand, the coupling portion may also have means for mechanically fixing the lamp unit 200 in the light support rail 700, which correspond in particular with fastening means of the light support rail 700. The abovementioned mechanical fastening means (not shown) of the luminous means 200 in the luminous support rail 700 can be designed, for example, as screw, clip or latching connections, but other connecting means are also conceivable, for example magnetic strips or adhesive bonds. For example, the supply lines 302 may be accommodated in elongated recesses, into which contact contacts of the lamp unit 200 will laterally retract by rotational movement in order to simultaneously provide an electrical and mechanical contacting of the lamp unit 200 with the light guide rail 700. Furthermore, the coupling portion may comprise at least a portion of the decoupling element 400. This makes it possible to simultaneously produce the connection of the lamp unit 200 to the data infrastructure with the assembly of the lamp unit 200 in the light guide rail 700, without having to make further adjustments or adjustments.

Further, it is also conceivable to connect the lamp unit 200 via cables to the decoupling element 400 in order to transmit an electrical signal which is at least a part of the has received data and is based on the preferably previously deflected optical signal. This preferred embodiment is shown for example in Figure 3 or the right side of Figure 9. Here, the luminaire unit 200 is connected via data lines 201 to the decoupling element 400 and in particular to the detector unit 410. In this case, the electrical signal generated in the detector unit 410 can be based only on a part of the optical signal, as shown in FIG. 3 by the first decoupled signal 611, or on the entire coupled-in optical signal 610.

Figures 4 and 5 show further embodiments in which the lamp unit 200 is connected via cables to the coupling-out element 400. In the two figures, it is also shown schematically, among other things, how the power supply of the lamp unit 200 in the light guide rail 700 is made possible by means of electrical leads 303. The electrical leads 303 are connected to the electrical supply lines 302, which in turn are themselves connected to the power supply 800.

FIG. 4 also shows an embodiment of the lighting system 100 in which only a single data channel 301 is provided. In this case, the decoupling element 400 can have only a single decoupling section 420, which is connected directly to the detector unit 410. On the other hand, FIGS. 5 and 9 show embodiments of the lighting system 100 in which a plurality of spatially offset elongated regions are used for signal transmission, whereby a plurality of optical data channels 301 are realized. Accordingly, a plurality of coupling-out sections 420 are preferably provided in this embodiment. The provision of multiple data channels 301 may have different reasons. In addition, FIG. 9 shows a plurality of light channels 301 ', which may be formed similarly to the data channels 301.

In general, the communication interface 501 may be configured not only to receive data from the communication network, but also to send data generated and stored in the lighting system 100 into the communication network. In the case that the communication unit 500 not only receives data from the communication network but also sends data to the communication network, preferably corresponding conversion devices are provided on the communication unit 500, with which, for example, the conversion of the optical signal into a digital or analog signal can take place ,

For the forwarding of the optical signal in two opposite directions, however, it may be necessary to use at least one data channel 301 for the received data present as coupled-in signals as well as for those of the Lamp units 200 sent as optical signals and provide the communication unit 500 directed data. Alternatively, of course, only one data channel 301 can be used for the transmission and reception of the optical signal, but this halves the bandwidth of transferable data in each transmission direction. However, the various data channels 301 may also be used to selectively transmit the coupled data to predetermined lamp units 200. Furthermore, it is also conceivable to associate individual data channels 301 with specific communication directions, such as the provision of a data channel 301 for transmitting the data received from the communication network and the provision of a further data channel 301 to enable the communication between the lamp units 200 and the provision of a third data channel 301 to transfer data back to the communication unit 500. These embodiments are merely intended to show which additional functionalities can be provided by the inventive lighting system 100, and are therefore still expandable.

The present invention is not limited by the above-described embodiments insofar as it is encompassed by the subject matter of the following claims. In particular, all features of the embodiments in any way with each other and can be combined and interchangeable.
