Description

Luminous module, arrangement of lighting modules and method for assigning addresses for lighting modules The present invention relates to a lighting module, an arrangement of

Light modules and a method for address assignment for side by side and / or mutually arranged light modules, each light module determines its position within the array and then each light module is assigned an address depending on the position.

Illuminating modules are often used as so-called video lights, for example in matrix-type arrangements, in order to be able to display video sequences over a larger area or to be able to display optical effects. As in the case of the arrangement of a plurality of luminaires in general, it is also necessary here for the position of each luminous module to be detected within the array and for each luminous module to receive a corresponding address so that each luminous module can be individually addressed as a function of the position in order to produce corresponding video sequences display or visual effects. For this purpose, the lighting modules can now for example be provided with addresses directly before installation or even during production. Through this

However, the approach results in the problem that each light module must be placed exactly at the position within the arrangement, which was previously determined, otherwise the corresponding address of the light module is assigned to a wrong position in a control unit. This would then result, for example, in a wrong control of the modules, whereby video sequences or optical effects would be displayed incorrectly.

Another way to address such lighting modules accordingly, is that after the installation of all lighting modules in the arrangement, each light module is manually assigned an address. As a result, for example, in the case of a matrix-like arrangement, the lighting module in the upper left corner can be provided with the address 1 and then the lighting modules are provided in succession with ascending addresses up to a lighting module in the lower right corner, whereby a control module is automatically aware of the position of the corresponding light module due to the address. In the case of manual addressing, there is the problem on the one hand that this procedure is associated with a considerable outlay, in particular in the case of larger arrangements, and, on the other hand, that manual errors may also result in operating errors which then in turn lead to incorrect activation of the lighting modules.

WO 2007 / 063487A1 discloses lighting modules which have so-called communication units on several sides of the lighting module. each

Communication unit of a light module is in each case with a

corresponding communication unit of a neighboring on the respective side lighting module, whereby a communication between two adjacent lighting modules is possible. In addition, it is provided that at a first

Luminous module of an arrangement of a plurality of light modules, a control unit is connected to the communication unit of the light module. Due to the connection between the light modules and the connection between the control unit and the first light module, all light modules are now connected to one another and to the control unit. In the address assignment, the control unit is now in communication with the first light module, whereby the first light module is assigned a first address, for example AI, or allocates itself. Subsequently, the first light module communicates with the to the corresponding communication units

connected lighting modules, in which case, for example, the order is followed first down, then left, then right, then above. Due to the

Information of the first light module is now assigned to the second light module an address increased by 1, for example A2, or assigns itself. These processes are repeated until all the lighting modules have an address. On the basis of the information as to which side of the light module an adjacent light module is connected, the positions of all the light modules, which then together with the corresponding addresses to the

Control unit to be transmitted. In the case of the method shown in WO 2007/063487 A1, there is no longer the danger that a lighting module is incorrectly driven due to a wrong assembly or a manual incorrect input. For the method shown there, however, now lighting modules are required, for example, in a rectangular or

square form of the light module four communication units, on each side of one, must have in order to implement the method. In addition, it is also necessary that each lighting module must be designed such that a communication with another adjacent lighting module is possible. The present invention is therefore based on the object to provide an alternative method, a lighting module or an arrangement of a plurality of lighting modules, with the aid of an error-free address assignment for the lighting modules of an arrangement is possible. The object is achieved by a method according to claim 1, a lighting module according to claim 12 and by an arrangement of a plurality of lighting modules according to claim 14. Advantageous developments are the subject of the dependent claims.

According to the invention, lighting modules, for example video modules, are provided which have sensors for detecting light. These brightness or light sensors are arranged within the lighting module in such a way that the sensors can detect the light emitted by adjacent lighting modules. For addressing a plurality of side by side and mutually arranged such lighting modules is determined by means of the sensors whether light is emitted from adjacent lighting modules and then determined with the help of this information, the exact position of the corresponding light module within the array. Based on the position of the respective lighting module then the lighting module is assigned a corresponding address.

Thus, in the present invention, it is no longer necessary for two adjacent lighting modules to communicate directly with each other, thus eliminating the need for arranging a plurality of communication units, such as in WO 2007 / 063487A1. Since lighting modules or video modules are generally square or rectangular, in the present invention in each lighting module is preferably detected on the left, right, upper and / or lower side, whether from adjacent

Lighting modules light is emitted. The lighting modules thus preferably have corresponding sensors on the left, right, upper and / or lower side of the lighting module.

Preferably, at the beginning of the addressing, the light of all the lighting modules of an arrangement is completely switched on and then the position of the first

Light module determined by the fact that no light is emitted from adjacent lighting modules on at least two adjacent sides of the light module. In a matrix-like arrangement of the lighting modules, for example, a first

Light module determined by the fact that on the left and upper side of a

Luminous module is received no light from adjacent lighting modules, whereby the arranged on the upper left in the matrix light module is detected or detected as the first light module.

After the light module arranged in the upper left corner has been recognized and has received, for example, the address 1, it can then further be provided that in this light module the light of the light module is switched off except for a lower part such that a leftward in a row adjacent light module detected no more light from the left and a downwardly adjacent light module still light detected. As a result of this partial switching off of the light in the first lighting module, the lighting module arranged to the right of this first lighting module now also detects that no more light is emitted from adjacent lighting modules both on the left and above. The light module then receives, for example, the address 2.

This procedure can then preferably be repeated until a lighting module not only left and above no more light from an adjacent

Detected light module, but also no right light detected. In this case, the light of the lighting modules of this series is then completely switched off and the position of the first lighting module of the next row is in turn determined by the fact that no light is emitted from adjacent ones on the left and upper sides of the lighting module Light modules is detected. The entire process is then repeated until the positions of all lighting modules in all rows are known and, accordingly, each lighting module also has an address. In the case of light modules which have, for example, only one light source, provision can be made for the light of this light module to be turned off first and then the light left in a row, once the position of a light module arranged in the upper left corner of a matrix-like arrangement has been determined first and the light module adjacent to each other in a column detects that the light of the light module has been switched off, in which case the position of the light module adjacent to the left in a row is determined by first detecting the sensors that neither left nor up Light is emitted from adjacent lighting modules and on the other hand by the previously obtained information that a left adjacent light module has recently switched off the light. Subsequently, the light of this light module is turned off again. Again, this procedure can be repeated until a light module detects not only left and top no more light, but also right, in turn, then the position of the first light module of the next row is determined.

Furthermore, it can then be provided again that the positions of all lighting modules in all rows are determined. As already with the

Previous procedure will now assign each luminous module ascending an address in order.

The invention will be explained in more detail with reference to embodiments and the accompanying drawing. Show it:

Fig. 1 sequence of addressing in a light module;

Fig. 2 matrix-like arrangement of a plurality of lighting modules with a bus; matrix-like arrangement of several lighting modules with two buses; FIGS. 2 and 3 show a plurality of lighting modules AH according to the invention, each having a sensor 1 on the left, top and right sides, which detects the light emitted by the adjacent lighting modules. In FIG. 2, all lighting modules AH are connected to a common bus. In contrast, in Figure 3, the lighting modules AD and H to a first bus and the

Light modules E-G connected to a second bus.

The addressing of the lighting modules A-H, which are connected to a common bus, as shown in FIG. 2, will be explained in more detail below with the aid of the flowchart shown in FIG.

At the beginning of the address assignment, all the light modules A-H are switched on first. For this purpose, for example, from a central control unit (not shown) to each light module, a data packet is sent via the bus in which the information is contained that all light sources or light sources of the light module,

for example, in the color white or another brightness or color to be turned on. In each light module is now continuously checked whether the left and top sensor 1 detects no light from adjacent lighting modules and thus each "dark" reports.

In the arrangement in FIG. 2, this initially applies only to the lighting module A, since in the case of all other lighting modules, light is detected either on the left or on the top of an adjacent lighting module. In module A is then checked whether an address of another light module has already been received via the bus. However, since the module A first determines that the upper and left sensor 1 detects no light, no address of another lighting module has yet been received, whereby the lighting module A is assigned the address 1 or assigns itself.

Subsequently, the lighting module A switches off its located in the upper region bulbs or light sources. Only in a lower area is then still emitted by the light module A light. In this case, it is necessary for the light in the module A to be switched off in such a way that the left-hand sensor 1 of the module B no longer detects any light, but the upper sensor 1 of the light-emitting module E still does.

After the light module A has switched off the light in the upper area, it checks nor, whether the right sensor 1 also reports that no light is emitted from a neighboring light module. If this is not the case, it shares that

Light module A via the bus the other lighting modules its address, in this case the address 1, with. Subsequently, the light module A lingers in a loop in which it continuously checks whether a packet is sent from another light module via the bus, that this other light module is the last light module in a row and in addition, whether an event for normal operation, i. that all the light modules are completely dark, has occurred. In the event that the light module A receives the packet via the bus, that another light module is the last in a row, the light module A completely shuts off the light and then returns to the loop just described. In the event that an event for the

Normal operation has occurred, the loop is aborted and the module A returns to normal operation. The above-described sequence of address assignment in the light module A is also used in the other lighting modules so, for example, in the light module B, the left and top sensor 1 only then reports that no light at both

Sensors is detected when the upper part of the light was turned off in light module A. In addition, module B already has an address for another one

Light module, here from light module A received. This address is then increased by 1 and then assigned to the light module B. As a result, the lighting module B in FIG. 2 receives the address 2.

Accordingly, the other lighting modules are addressed, in

Light module D, the right sensor 1 reports that no light is emitted from an adjacent light module, whereby the light module D in addition to its address received also via the bus notifies that it is the last light module in the series. On the basis of this information, the light is then completely switched off in the lighting modules AD, as a result of which the upper and left sensor 1 in the module E reports that no more light is emitted by adjacent lighting modules. For complete shutdown of the light in a row by the information of the light module D that it is the last light module in the series, it should also be noted that only light modules that already have an address, dark accordingly allowed to switch. All other light modules, in this case the light modules EH use only the transmitted from the light module D address.

After the light module H has an address, the light of the lighting modules in the second row is completely switched off. As a result, all lighting modules are switched off in the arrangement, whereby all lighting modules can return to normal operation. This can be done, for example, by switching the device off and on again, by playing back normal frames, or by running the maximum time required to assign all the addresses.

For address assignment in the respective lighting module is also to be noted that it is also possible that a lighting module receives multiple addresses or assigns itself, this lighting module then tells the other lighting modules the last address used by him over the bus. Thus, it would be conceivable, for example, that the luminous module A is assigned the addresses 1 and 2 and, accordingly, the luminous module B receives the address 3, the luminous module C receives the address 4, etc.

The method described above is particularly suitable when the

Luminous module has a plurality of lighting means or light sources, which allow the light can be switched off in an upper part. For example, lighting modules or video modules that have a multiplicity of pixels are conceivable here.

For the case, however, that the respective light module, for example, only one

Light source or a light source, offers a slightly different

Procedure for addressing the lighting modules. In contrast to the previous method, now that the light module A has been assigned the address 1 or has assigned itself, the light is completely switched off. This switching off the light now registers both the left sensor 1 in the light module B and the upper sensor 1 in the light module E. Accordingly, now recognizes the light module B, that it is the next light module in the series and thus gets the next address assigned or assigns itself. in the

In contrast, the light module E knows that it is not the next one due to the information that the light on the upper sensor 1 and not on the left has been switched off Module in the row, but the first module in the next row.

Accordingly, the light module E waits until the light module G the

Information comes that it is the last light module in the series. The other steps of the addressing are identical to the method described above.

In the arrangement shown in Figure 2, the lighting modules are all connected to a common bus. In contrast, an arrangement is shown in Figure 3, in which the lighting modules A-D and H to a first bus and the

Light modules E-G are connected to a second bus.

The lighting modules A-H shown in FIG. 3 are again lighting modules that can switch off an upper part of the light, while a lower part of the lighting module continues to emit light. The method of addressing the lighting modules A-D now corresponds to the first method presented with reference to FIG. Then, after the lighting module D outputs the message on the first bus that it is the last light module in the series, in turn, the light of the light modules A-D is completely turned off. As a result, the left and upper sensor 1 of the lighting module E reports that no more light is detected, as a result of which the lighting module E is assigned an address or assigns itself. Now that the light module D outputs its address only on the first bus and not on the second bus behaves the light module E as if it were the first light module and accordingly receives the address 1. Then the light modules F and G are addressed accordingly. The light module H then determines that the left sensor 1 adjacent

Luminous module G has been switched off and then receives an address or assigns itself. It should be noted here that the last address transmitted via the first bus is that of the lighting module D and, accordingly, the lighting module H receives an address which is increased by 1 relative to the address of the lighting module D.

After then the light module H also has an address, the light module H turns off its light completely, as well as the right sensor 1 no light is detected. This switching off the light of the light module H also detects the right sensor 1 of the light module G, but no address is communicated via the second bus, since the light module H only via the first bus its Address informs. As a result, the lighting module G assumes that the subsequent light module H is hanging on another data bus and waits until all

Light modules of the other bus were addressed. Subsequently, the light module G behaves as if it were the last light module in the series and accordingly transmits to the other light modules of this bus the message that it is the last light module in the row, whereby the light modules E, F and G are completely turned off.

Thus, it is also possible with the present invention that lighting modules A-H are addressed in an arrangement which are connected to different buses, the addressing starting, for example, in each bus with address 1.

The methods of addressing presented here in detail are merely preferred embodiments which, however, can also be modified. The essential idea of the invention here is that with the help of in the

Light modules A-H arranged sensors 1 and a specially matched light output of the modules is determined, at which position the respective light module A-H is positioned within an array.

Accordingly, the present invention is not limited to the use of exactly three sensors 1. Furthermore, the illustrated matrix-like arrangement of the lighting modules A-H is not absolutely necessary. It would be

for example, also possible that the lighting modules A-H are arranged in other arrangements, for example in a row.
