Description

The invention relates to a lighting arrangement, a lighting system comprising at least two lighting arrangements and a method for operating a lighting system, for example for a building part. A lighting arrangement is understood in particular to be a light source operated by an operating device.

Nowadays, a lighting arrangement, for example a luminaire with at least one LED as lighting means, has an operating device, for example an electronic ballast, which has a control input. via this control input of the operating device, the operating device receives control parameters for operating a light source or sends status reports or error messages of the light source or the operating device to a central control unit of a lighting system in a building. In order to be able to transmit a control signal to the corresponding operating devices, these operating devices have a unique address in the lighting system. The control signal is transmitted, for example, by means of a standardized interface, for example the Digital Addressable Lighting Interface, DALI interface for short.

The distribution of these unique addresses to the operating devices is generally independent of the respective location of the lighting arrangement.

Today's lighting systems are divided into so-called lighting subsystems. Each of these illumination subsystems includes a plurality of illumination assemblies. Sometimes it is desirable to operate lighting arrangements of a lighting subsystem with a common control signal or at least to obtain a common light behavior within this subsystem or to operate the lighting subsystem detached from other lighting subsystems. For this purpose, associated illumination arrangements of a lighting subsystem are combined in so-called control groups. The affiliation depends, for example, on the location at which the lighting arrangements are arranged, for example, a common corridor, an open-plan office or the like. They then form a lighting subsystem within a lighting system in a building.

The assignment of a lighting arrangement to a lighting subsystem nowadays takes place manually, by an operator of the lighting system, after the identification of the respective lighting arrangement and its relative position to a second lighting arrangement, linking this to the respective lighting subsystem. This is also referred to as locating the respective lighting arrangement. For this purpose, for example, the lighting arrangement is switched in a flashing mode, so that the operator can clearly identify the lighting arrangement and according to their identity manually assigns a lighting subsystem.

The lighting subsystems are then made known to the respective operating devices. This is done in particular by programming the respective operating device on the lighting subsystem. For this purpose, so-called group addresses are provided, with which the operating devices belonging to a lighting subsystem can be jointly controlled in an operating phase.

The localization and identification of the respective lighting arrangement and the programming of the operating device is a very time-consuming process.

From the WO 2011/067367 A2 A method for optical signal output of operating parameters of an operating device for an LED light source is described. The respective illuminant emits an optically or acoustically coded signal. For example, a white sum light can be used as the light source. A subset of the LEDs forming the illuminator emits non-white light to enable optical signal output. This non-white signal output then contains operating parameters, for example an operating time, of the respective luminous means.

In the WO 2013/023955 A2 Lighting networks are provided in which a network address of an operating device is stored in a memory unit, to be subsequently transmitted wirelessly to another operating device.

In all of the described methods, a user must first make manual programming of the lighting subsystem.

Today, a lighting arrangement is operated independently of surrounding lighting arrangements. A clear facilitation of locating and programming a lighting system within a building would be if the neighboring lighting arrangements or a central control of the lighting system were informed about the type and number or the type of surrounding lighting arrangements, for example to be able to conclude a common lighting subsystem ,

An object of the present invention is therefore to simplify the identification of a lighting arrangement. Furthermore, the programming of a respective operating device of a lighting arrangement in a lighting system is to be simplified and, if possible, automated.

Another problem is the replacement of one or more lighting arrangements or operating devices for a lighting arrangement in a lighting system. For this purpose, a renewed localization must always be carried out in order to be able to assign the exchanged illumination arrangement to the respective illumination subsystem. A clear relief would be given if the control information would be available directly after the replacement of the lighting arrangement or the respective operating device without additional activities.

These objects are achieved by the measures described in the independent claims. Advantageous embodiments are described in the respective dependent claims.

In a first aspect of the invention, a lighting arrangement, for example a luminaire with at least one LED as illuminant, an operating device, a controllable by means of the operating device lighting means for emitting light and controllable by means of the operating device position lighting means.

The position illuminant transmits position information of the illumination arrangement. The position information comprises at least one orientation information of the illumination arrangement. The illumination arrangement is furthermore equipped with a sensor element for receiving position information of adjacent illumination arrangements.

In this way, an automatic transmission of position information is made possible, in which at the same time an alignment information of the illumination arrangement is transmitted.

By means of the position information, a receiver of the position information learns that a further illumination arrangement is present in the reception area of the sensor element.

By means of the alignment information, a receiver of the position information also learns from which direction the position information was sent. For example, a sensor element in the illumination arrangement receives the position information from an adjacent illumination arrangement. By means of the alignment information, the receiver of the position information also learns in which relative position the emitting illumination arrangement is in relation to the receiver of the position information.

Position information can be received by the sensor element. In this case, the position information which is received in the sensor element has been emitted by a lighting arrangement which is adjacent to the illumination arrangement. In this way, adjacent lighting arrangements can recognize each other and determine on the basis of the alignment information in which relative position the lighting arrangements are related to each other. The information about which position information was received by the sensor element is stored in a memory area of the illumination arrangement and can be evaluated, for example, by the operating device of the illumination arrangement or a higher-level control device of an illumination system. Thus, the control unit or the operating device receives the information which lighting arrangement has which adjacent lighting arrangement.

In a preferred embodiment, the position information also includes identification information of the illumination arrangement. As an identification information, for example, an operating address of the operating device is provided, this operating address is introduced during a manufacturing phase or a first commissioning in the operating device. Alternatively or additionally, the identification information is a serial number of the operating device or the lighting arrangement. Alternatively or additionally, the identification information is a random number, which is uniquely assigned in the lighting system in which the lighting arrangement is mounted.

The identification information and / or the alignment information can be transmitted as modulated light power, wherein an operating device of an adjacent lighting arrangement, which can receive this modulated light power by means of its sensor element, demodulates this light power to receive the alignment information and / or the identification information.

In a preferred embodiment, the operating device in a first operating phase of the lighting arrangement controls the lighting means as position lighting means for emitting the position information. In a second operating phase, the operating device of the lighting arrangement activates the light source for emitting light. Thus, only one light source is necessary to be controlled both as a light source in the lighting arrangement of the operating device and also as Position lights available to stand. In this way, the illuminant can also be used as a position illuminant, so that components can be saved.

The emitted light of the position illuminant differs during the first operating phases from the light of the luminous means, in particular by a wavelength different from the luminous means, by a changed temporal variance of the light emission, by a changed frequency and / or by a changed light intensity. For example, in the first operating phase, a quasi-monochromatic light, for example the colors green, blue, yellow or red, is emitted in a frequency perceptible to the human eye, for example below 20 hertz. For example, in the second phase of operation, polychromatic light, for example white light, is emitted at a frequency which is imperceptible to the human eye, for example above 50 hertz.

This first phase of operation may also be referred to as the installation phase or the identification phase of the lighting system.

In a second operating phase, the lighting arrangement emits the light by means of the lighting means. This second phase of operation is a normal operating phase. The light of the illuminant is used, for example, the illumination of the building part, a work surface in an office or open-plan office or a corridor. By means of a switching element, the light source of the second operating phase is activated or deactivated. The operating device of the lighting arrangement detects the state of the switching element. Thus, in the second operating phase, the light source can be operated as intended, whereas in a first phase of operation, the position information is transmitted with the alignment information.

The sensor element preferably receives the position information in a second operating phase of the illumination arrangement, in particular when the illumination means is deactivated, so as not to influence the sensor element.

Alternatively or additionally, the lighting arrangement is switched over between the first operating phase and the second operating phase at regular time intervals. In this case, the first phase of operation can have a much smaller proportion of time than the second phase of operation.

In a preferred embodiment, the position information is a modulated light output of the position illuminant. Thus, an electrical current is provided by the operating device, which causes the position lighting means for emitting modulated light powers. In this case, for example, the electric current is modulated. If necessary, specially agreed protocols which are suitable for unambiguously identifying a lighting arrangement are used as the modulation data. Thus, the light output of the position illuminant is modulated according to an agreed protocol. For this purpose, for example, a predefined switch-on sequence or switch-off sequence can be used. Alternatively or additionally, the frequency of the modulated light power is coded.

Thus, it is proposed according to the invention that the illumination arrangement in addition to their actual bulbs so-called position illuminant, based on which an information on the orientation of the illumination arrangement is detected in an evaluation of the emitted position information and the sensor elements by means of which the position information of adjacent lighting arrangements can be received ,

In a preferred embodiment, the position illuminant has at least two light sources spaced apart from one another, wherein the emitted light of a first light source has a first wavelength and wherein the emitted light of a second light source has a second wavelength different from the first wavelength. The wavelengths are then the alignment information of the illumination arrangement. In this way, by a spectral composition of each individual light source of the position illuminant, an alignment information is sent in addition to a position information.

In a preferred embodiment, the position illuminant has a predefined, depending on the time variable, radiation characteristic. A predefined change in the emission direction of the position illuminant, which changes over time, enables detection of the direction from which the light was emitted. Thus, a lighthouse effect is achieved, due to which an adjacent illumination arrangement can be located in a simplified manner and the received position information also contains information about which direction this position information was sent from. For example, a first light source of the position illuminant may be mounted on a first side of the illumination assembly. A second light source of the position illuminant may be disposed on a second side of the illumination arrangement opposite or spatially spaced from the first side. The light intensity of the light sources can increase and decrease periodically. For example, in one period of the light intensity fluctuation, the light intensity of the first light source may be timed meanwhile the second light source has a time-increasing light intensity at the same time. Alternatively or additionally, only the light intensity of one of the light sources of the position illuminant decreases.

In a preferred embodiment, the position lighting means is arranged in an edge region of the lighting arrangement. If, in addition, a plurality of position illuminants are provided at different edge regions of the illumination arrangement, it can be concluded by setting the respectively emitted wavelengths of the individual light sources of the position illuminants to determine whether the position information received by means of the sensor element was transmitted by an adjacent illumination arrangement that is relatively left-facing or is arranged to the right or front or back of the receiving lighting arrangement. Thus, the relative position can be concluded with an adjacent illumination arrangement.

In a preferred embodiment, the position lighting means has at least three light sources, which together cover an area of 360 ° in the horizontal space plane. In this way, this space level is completely covered by the position lighting means, wherein the individual light sources of the position illuminant preferably have different wavelengths, different modulated light outputs or different light output per unit time, so that an adjacent lighting arrangement can close to the relative position.

In a preferred embodiment, at least one fourth light source of the position illuminant is arranged vertically spaced from at least one of the three light sources of the position illuminant. In this way, vertical information can also be transmitted with the position information. This is particularly helpful if the lighting arrangements are not all located in a same horizontal plane in a building part, for example in the installation of wall lights, floor lights and / or ceiling lights.

In a preferred embodiment, the lighting means is formed of a plurality of light sources, wherein a part number of the light sources can be controlled by the operating device as light sources of the position lighting means. In this way, various subgroups of the plurality of light sources can be formed to send the position information with the alignment information. Again, the control of different wavelengths or modulated light power is provided to transmit an alignment information as position information with.

According to the invention, adjacent lighting arrangements can identify and locate each other. For this purpose, the lighting arrangements are switched sequentially between a first operating phase and a second operating phase, wherein in a second operating phase, the sensor element receives position information of adjacent lighting arrangements.

The reception of position information preferably takes place within a second operating phase. In this second operating phase, the received position information is stored in a memory area of the operating device. For this purpose, a lighting system with a clear timestamp is also stored. This received position information is provided to a central control unit of the lighting system to create a map of the lighting arrangements in the building part. This map takes into account which lighting arrangement could receive which position information by means of its own sensor element. In particular, the relative position of the mutually-localizing lighting arrangements is taken into account. These floor plan data are then used to create group addresses for the lighting system and to distribute them to the respective operating devices.

If a lighting arrangement does not receive any position information during a second operating phase, this is likewise logged in the memory area.

In this way, lighting arrangements can be created, which automatically locate each other and are also automatically assigned to a lighting subsystem via a control unit. This simplifies a corresponding group address sent to the belonging to the group operating devices of the lighting arrangements and stored in the respective operating devices of.

In a second aspect of the invention, an illumination system with at least two illumination arrangements according to the preceding type and a control unit is provided. The first illumination arrangement has a first sensor element, wherein the first sensor element receives position information of the second illumination arrangement and provides it to the control unit. Furthermore, the second illumination arrangement is formed with a second sensor element, wherein the second sensor element receives a position information of the first illumination arrangement and provides the control unit.

In this way, not only lighting arrangements and their position information with alignment information are received, but also information about which lighting arrangement can locate which adjacent lighting arrangement in a lighting system is obtained. For example, if it is provided in a building plan that two adjacent lighting arrangements must locate and this is not the case on the basis of the sensor element data, it is possible to conclude that at least one of the lighting arrangements in the lighting system is defective. In this way, an automatic exchange command can be generated and transmitted to a building equipment unit. Moreover, lighting arrangements of a building part are combined in a lighting subsystem. For example, a lighting subsystem is a confined space or open plan office or corridor within a building or part of a building. Alternatively, complete floors can be set up as a lighting subsystem.

In a preferred embodiment, the control unit creates group addresses for the individual lighting arrangements on the basis of the provided position information of the lighting system. The respective group address is sent to the operating device of the respective lighting arrangement and stored in a memory area of the operating device.

In a preferred embodiment, the control unit evaluates the received position information of the respective sensor elements and uses the evaluation to create a map of the illumination arrangements in which the relative position and position of all illumination arrangements of the illumination system are entered on the basis of the position information provided. This takes into account, in particular, which lighting arrangements can locate one another and which can not. For this purpose, a time stamp is evaluated so that the control unit can evaluate which lighting arrangement has sent which position information at what time and which lighting arrangement has received which position information at which time. The time stamp is unique to the lighting system or at least to the illumination subsystem.

An automatic creation of lighting subsystems and the entry of group addresses for the individual lighting arrangements are thus obtained. In the subsequent step, the operating devices of the individual lighting arrangements can be supplied by the control unit with the group address, so that a subsequent control of a lighting subsystem can be simplified.

In a preferred refinement, the site plan is compared with a provided site plan and planning information contained therein by the control unit. Thus, a building floor plan can be used to reconcile planning information with actually existing lighting situations. In this way, replacement of defective lighting elements or possibly a mistake in a design can be detected and corrected accordingly.

In a further aspect of the invention, a method for operating a lighting system is provided. The method comprises the method steps: emitting position information by a first illumination arrangement according to the previously described type; Receiving the transmitted position information by a second illumination arrangement according to the previously described kind; Providing the received position information in a control unit of the lighting system; Generating a group address based on the received position information in the control unit; Sending the group address to an operating device of the first lighting arrangement; and storing the group address in a memory area of the operating device.

Preferably, a third illumination arrangement located in spatial proximity to the first illumination arrangement also receives the position information and also provides this position information to the control unit.

In a preferred embodiment, the control unit controls all lighting arrangements with the same group address simultaneously. Thus, a lighting subsystem specific drive can be done automatically. In this way, all lighting arrangements associated with the lighting subsystem can be switched on or off at the same time and / or experience daylight-dependent dimming and / or the like.

The invention or further embodiments and advantages of the invention will be explained in more detail with reference to figures, the figures only describe embodiments of the invention. Identical components in the figures are given the same reference numerals. The figures are not to be considered as true to scale, it can be exaggerated large or exaggerated simplified individual elements of the figures.

2 B the second embodiment of a lighting arrangement according to the invention according to 2a in side view.

3 an inventive lighting system.

In 1 is a first embodiment of a lighting arrangement according to the invention 1 represented, for example, may be a lamp with at least one LED as the light source.

The lighting arrangement 1 includes a control gear 4 , which can be operated with a supply voltage (not shown). The operating device 4 is especially intended to a light source 2 to drive to emit light. In this case, the light bulb 2 For example, be a light emitting diode LED. Alternatively, the bulb 2 a so-called LED array consisting of a plurality of LEDs. The circuit required to convert the voltage from a supply voltage to a DC voltage is in the operating device 4 contain. Furthermore, the operating device includes 4 a control unit with which an energy-efficient control of the bulb 2 can be done. For this purpose, for example, a switching regulator is provided within the operating device.

Alternatively, the bulb 2 also be a gas discharge lamp, which is still used today for use in buildings.

According to the invention is in the lighting arrangement 1 a position illuminant 3 intended. The position light 3 according to 1 at least one, preferably two or even more light sources 3a and 3b on. According to the example of 1 the position lighting means are arranged in an edge region of the lighting arrangement.

Furthermore, a sensor element 10 illustrated, which is adapted to position information of adjacent lighting arrangements 1 (not shown) to receive.

The position light 3 is in a first phase of operation of the lighting arrangement 1 from the operating device 4 driven. Here is the light source 3a intended to emit red light. The light source 3b is intended to emit green light. An identical adjacent lighting arrangement 1 receives by means of the sensor element 10 this position information. By dissolving the wavelengths in a sensor element 10 experiences an adjacent lighting arrangement 1 an alignment information of the emitting lighting arrangement 1 due to the different wavelengths of the light sources 3a . 3b of the position illuminant 3 , Alternatively, a different light intensity of the light sources 3a . 3b be used to infer the alignment information of the lighting arrangement. Alternatively or additionally, the light intensity of the light sources 3a . 3b vary in time. Alternatively or additionally, the main emission direction of the light source 3a . 3b vary in time.

The sensor element 10 is in particular an illuminance measuring element, for example a photodiode, which can detect different wavelengths in a location-related manner.

The operating device 4 has an interface to by means of the sensor element 10 to be able to provide received position information to a control unit of the lighting system (not shown). From this control unit, the lighting arrangement receives a group address based on the provided position information, which is stored in a memory area (not shown), and with which the control unit, the operating device 4 can address.

Preferably, the housing of the luminaire, at least the light exit cone thereof, is not rotationally symmetrical, so that it can assume different distinguishable orientations.

In 2a is a plan view of a second embodiment of a lighting arrangement according to the invention 1 shown. The lighting arrangement 1 is a circular lighting arrangement. In the middle is the bulb 2 arranged, which for emitting light from the operating device 4 is controlled.

The circular illumination arrangement is divided into three sectors, each sector having 120 °. In each of the sectors is a light source 3a . 3b and 3c of the position illuminant 3 arranged.

In each sector there is once again a sensor element 10 to position information of adjacent lighting arrangements 1 (not shown) to receive. Alternatively, only one sensor element can be used 10 be provided.

According to the invention, it is now provided that each of the light sources 3a . 3b and 3c of the position illuminant 3 Light of a wavelength emitted by the wavelengths of the other light sources 3a . 3b . 3c is different. For example, the light source 3a arranged to emit light of a wavelength in the red visible range. The light source 3b is set up to emit light in the green visible region of the light. The light source 3c Finally, it is designed to emit light in the range of yellow visible light.

In a first variant, all light sources radiate 3a . 3b . 3c these different wavelengths at the same time. Will this light emission from a sensor element 10 an adjacent lighting arrangement 1 received, it can be concluded because of the different wavelengths, where this adjacent lighting arrangement relative to the sensor element 10 located. The direction is thus based on the wavelength of the individual light sources 3a . 3b . 3c of the position illuminant 3 established.

In a second variant, all light sources radiate 3a . 3b . 3c these different wavelengths at different times. Will this light emission from a sensor element 10 an adjacent lighting arrangement 1 received, it can be concluded because of the different wavelengths and / or the different temporal radiation, where this adjacent lighting arrangement relative to the sensor element 10 located. The direction is thus based on the wavelength and the time window of the radiation of the individual light sources 3a . 3b . 3c of the position illuminant 3 established.

This is especially possible if all lighting arrangements 1 be mounted and operated within a building part according to the same rules. For example, it is determined that all lighting arrangements 1 On a first side emit red light and emit green light on a second, opposite side, so may a sensor element 10 upon receipt of the emitted different wavelength, conclude whether the illumination arrangement is located to the left or right of it. The lighting arrangements 1 are sequentially switched to the first phase of operation. In this case, only one lighting arrangement is preferred 1 per unit of time in the first phase of operation. All other illumination arrangements of the illumination system are connected in the second operating phase, wherein in particular the respective sensor elements are adapted to receive the position information sent by the illumination assembly located in the first operating phase and to log it with a time stamp or to log only the time stamp if not received.

In 2 B is a side view of an in 2a shown lighting arrangement shown. It is only schematically indicated that a fourth position illuminant 3d vertically spaced from a fifth position illuminant 3e in the lighting arrangement 1 is appropriate. Will now be a wavelength of the position illuminant 3d radiated, the one wavelength of the position illuminant 3e is different, it can also be concluded that a relative position in a vertical plane. In this way, the lighting arrangements 1 also be characterized according to their height position.

The embodiments according to 1 and 2 thus contain a lighting arrangement 1 which at least one position illuminant 3 having. The position light 3 is in particular by light sources 3a . 3b . 3c arranged at the end points of the lighting arrangement. This may be, for example, the front side of a linear luminaire or the radiation direction or the back of a radiator. In the case of circular lighting arrangements, in particular the division of a horizontal plane with sectors is provided for imaging a 360 ° environment. Through the light sources 3a . 3b . 3c of the position illuminant 3 becomes the orientation of the lighting arrangement 1 Clearly described in the room. The position light 3 is clearly coded. In particular, the spectral composition of a light signal of the individual light sources of the position illuminant 3 be different to generate unique alignment information.

Alternatively or additionally, a modulation of the light intensity of the light sources 3a . 3b . 3c of the position illuminant 3 respectively. It can also be provided that both the spectral composition and a digital modulation of the light intensity at that of the light sources 3a . 3b . 3c of the position illuminant 3 emitted light is applied. Preference is given to the installation of the lighting arrangement 1 take care that the lighting arrangement 1 in the building is mounted in the same orientation.

In the 1 and 2 also shown is at least one sensor element 10 , This sensor element 10 evaluates the received position information of the adjacent illumination arrangement 1 out. It is particularly possible that when using several different wavelengths for the light sources 3a . 3b . 3c of the position illuminant 3 also a corresponding number of sensor elements 102 for receiving the respective wavelength in the illumination arrangement 1 is provided.

Each operating device 4 a lighting arrangement 1 receives a unique operating address, which is, for example, a random encoding, a serial number and / or an initial address. This identification information becomes part of the position information from the position illuminant 3 shipped with. Thus, in addition to the alignment information, the identification of the illumination arrangement also becomes simultaneous 1 transmitted as position information. The operating device 4 In particular, the lighting arrangement can be set up 1 operate in a first phase of operation and in a second phase of operation. In this case, in a first phase of operation of the lighting arrangement 1 the operating device 4 operated such that the position lighting 3 be driven to send position information. The first operating phase can therefore be referred to as a configuration phase or initialization phase. In a second operating phase of the lighting arrangement 1 is the operating device 4 to set up the bulbs 2 the lighting arrangement 1 to drive to emit light and by means of the sensor element 10 To receive position information.

The first operating phase and the second operating phase can take place at the same time, so that both the position lighting means 3 as well as the bulbs 2 from the operating device 4 be controlled. Alternatively or additionally, a first operating phase takes place, in which the transmission of the position information by the position illuminant 3 the lighting arrangement 1 he follows. For example, a first phase of operation may be much shorter in time than a second phase of operation.

Every lighting arrangement 1 can also be to a control command, the respective coding of the position lighting 3 change and obtain an alternative modulation of the light intensity or the spectral composition. Thus, a control unit 8th (not shown in 1 or 2 ) in a lighting system, each lighting arrangement 1 selectively control and change the position information accordingly. In this way, error checks or a new configuration of the lighting system can be sought.

Preferred is any lighting arrangement 1 with a sensor element 10 equipped and also learns about the control unit 8th which lighting arrangement 1 in the lighting system at which time sends a position information. Due to the relative position of the adjacent lighting arrangement 1 Due to the position information and the respective alignment information, the illumination arrangements locate 1 independent. The information about the relative position can be found in particular in the operating device 4 every lighting arrangement 1 be evaluated or from the central control unit 8th of the lighting system 6 be evaluated.

Once all lighting arrangements 1 have sent their position information, is any lighting arrangement 1 in the lighting system 6 as well as the control unit 8th informed about which lighting arrangement 1 with which operating address in which local relationship to another lighting arrangement 1 with their respective operating address stands as identification information.

The position lights 3 can be part of the bulb 2 be. Alternatively, they are integrated as remote elements only for the purpose of the position information transmission.

The number and orientation of the sensor elements 10 or the position light 3 per lighting arrangement 1 are variable and dependent on the degree of freedom and the possibility of lighting installation.

In 3 is a first embodiment of a lighting system 6 with four lighting arrangements 1 shown in the manner previously described. Here are the lighting arrangements 1 according to the 2a respectively. 2 B designed. Thus, the lighting arrangements 1 circular and have three sectors of 120 ° each. In this case, a first sector 1 of each lighting arrangement I . II . III or IV adapted to emit light of red wavelength. A second sector 2 of each lighting arrangement I . II . III or IV is designed to emit light of a yellow wavelength. Finally, a third sector 3 of each lighting arrangement I . II . III or IV intended to emit light of a green wavelength. Thus, a coding is set, which in the assembly of the lighting arrangements I . II . III . IV to take into account.

Thus, receiving red light from an adjacent lighting assembly 1 in that these are frontal to the respective lighting arrangement 1 located. If yellow light is received, then the lighting arrangement is located 1 relative to the right of the respective lighting arrangement 1 , Respectively, when receiving green light, the lighting arrangement becomes 1 to the left of the respective received illumination arrangement 1 be arranged. Every lighting arrangement 1 has an individual address, marked by the markings I . II . III or IV ,

In the lighting system 6 a configuration phase is planned. In this configuration phase, all lighting arrangements become sequential 1 operated in succession in a first phase of operation. The lighting arrangements not in each case in the first operating phase 1 are in the second phase of operation. Per lighting system 6 is only a lighting arrangement 1 for sending position information with alignment information. At the start of a corresponding method for operating the operating system, the lighting arrangement sends I Position information about the light sources 3a to 3c of the position means 3 out.

In 3 are the emitting areas as position light I.1 . I.2 and I.3 shown. With the sending in the configuration phase of the lighting arrangement I the transfer of an address from a storage area of the operating device also takes place 4 the lighting arrangement 1 ,

The lighting arrangement II receives position information I.3 on its left side, in particular the green wavelength at the sector 2 and the time of receipt are acknowledged. The operating device 4 or the higher-level control unit 8th of the lighting system 6 evaluates this reception of position information. The evaluation shows that the lighting arrangement II with the same orientation to the right of the illumination arrangement I located. At the same time register the lighting arrangements III and IV no position information. This is justified by the fact that the lighting arrangement I too far for the reception area of the sensor element 10 removed for the lighting arrangement III is and that a wall as another optical obstacle 7 receiving position information in the lighting assembly IV from the lighting arrangement I in derogation.

The control unit 8th registers the reception of all position information or the non-receipt of position information per time unit. As each lighting arrangement sequentially transmits once, the control unit can 8th detect which lighting arrangement can be located by which lighting arrangement at what time.

Were all received or not received position information of the control unit 8th provided, the lighting arrangement I caused to prevent the transmission of position information. This is the lighting arrangement I in a second phase of operation by means of the operating device 4 connected. At the same time the lighting arrangement II switched from a second phase of operation in a first phase of operation. To start sending position information. The lighting arrangement receives I a signal II.2 (not shown) of the lighting arrangement II In particular, the yellow wavelength at sector 3 and the time of receipt are acknowledged. The operating device calculates from the received position information 4 or the control unit 8th that the lighting arrangement I is aligned identically as the lighting arrangement II and that the lighting arrangement I to the left of the lighting arrangement II is arranged. Furthermore, the lighting arrangement also receives III a position information II.3 In particular, a green wavelength at sector 2 and the time of receipt are acknowledged. It turns out in the control unit 8th or the operating device 4 concluded that the lighting arrangement III is aligned identically as the lighting arrangement II and that the lighting arrangement II to the left of the lighting arrangement III is arranged.

The control unit 8th terminates the emission of position information of the lighting arrangement II by the lighting arrangement II is switched to the second phase of operation. Then, the transmission of position information of the lighting arrangement III by switching the lighting arrangement III obtained in a first phase of operation. The control unit determines 8th that the lighting arrangement III is aligned identically to the lighting arrangement II and the lighting arrangement III to the right of the lighting arrangement II is arranged.
