    description
    PROCESS FOR STARTING A LIGHTING SYSTEM
    The present invention relates to a method for starting up a lighting system, being assigned to the lights of the system operating addresses in the context of the method.
    Lighting systems of modern design, which are particularly intended to illuminate larger buildings or facilities, usually offer the option to turn the lights arranged in different areas not only on the arranged in the respective areas switch or dimmer or off or in to adjust their brightness. Instead, it is also possible remotely control the lights from a central control device. As a result, a comfortable lighting control for the illumination of larger buildings or complexes is achieved. Such lighting systems therefore usually have one or more commanders, which can address and control the decentralized arranged in different areas and connected to a power supply lamp operating devices via commands. Often, a communication from the lamp operating devices to the command device is provided in order, for example, to report incorrect operating states. In this way, not only a comfortable lighting control but also a reliable monitoring of the state of the lighting system is made possible.
    The control of the individual lamp operating devices via an individually assigned address, via which they can be addressed by the central control unit. Preferably, the lamp operating devices are assigned so-called. Operating addresses, which among other things, also take into account the arrangement of the light sources in the different areas of the building to be illuminated. In addition, it is also possible to combine the light sources arranged in the different rooms into groups, which can be addressed jointly by the central control unit.
    Control systems for lamp operating devices, which allow individual control of the devices, often work today according to the so-called. DALI (Digital Addressable Lighting Interface) standard. This is an interface developed by the lighting industry for the transmission of digital control commands between a central control unit and distributed consumers. A so-called DALI bus can then be used to connect up to 64 luminaires to a command transmitter, which luminaires can be individually addressed.
    Since the corresponding lamp operating devices in their production and installation in the lighting system have no operating address, it must be assigned as part of an initialization procedure, which is carried out according to the DALI standard as explained below.
    After installation of all lamp operating devices without regard to their spatial arrangement, the operating devices of the individual lights are first connected to the DALI bus, so the control line. The subsequent supply of power to the lamp operating devices causes each lamp operating device to generate an individual random address for itself. From the central controller from the command is then issued that the lamp operating devices report with their random address, which internally at the commander a list of all devices is created, which also contains the information about which random addresses the devices are each contactable.
    However, since this random address is not yet taken into account the spatial arrangement of the lamp operating device and is unsuitable for the current operation long, in a subsequent step the devices are then assigned to each intended for later operation operation address. This is done by the central command generator first calling a first random address, which has the consequence that the corresponding light is identified, that is, for example, it lights up. Now a person has to determine in which room this luminaire is located. As soon as the position has been determined, a corresponding feedback is sent to the control center. Another person then enters the place and the group of the reporting light into the controller, with the result that this light is then assigned a suitable operating address. One after the other, all random addresses are dealt with in this way until all luminaires have been assigned an operating address. This is stored in each case in a corresponding memory of the lamp operating device.
    In the above embodiments, it has been assumed that each luminaire has a single operating address under which it is driven by the central control unit of the system. From the prior art, however, luminaires are also known in the meantime, which have a plurality of separate units for emitting light, which can be adjusted independently of one another in terms of their brightness and / or color or color temperature. In the simplest case, for example, it is a question of luminaires which, on the one hand, have light sources for direct light emission and, on the other hand, light sources for indirect light emission. However, in addition, luminaires are also known in which the direct light output is further subdivided, for example into a strongly directed portion, which is then used, for example, to illuminate workplaces or targeted illumination of objects, as well as a rather diffuse light component over which a large but less intensive additional or backlight is created. Also lights are known which have individual lighting modules, which are arranged, for example, in an elongated arrangement one behind the other or in a matrix-like manner and can each be set individually with regard to their light output.
    In these more complex lights, it is usually not sufficient if the control is done only with a single operating address, because then the multiple options for light output could not be used or only inadequate. Usually, the luminaire is then assigned to several operating addresses, under the use of which individual brightness setpoints for the individual units or at least groups of units are then transmitted in each case. In this case, then several operating addresses must be assigned to the light.
    Come in such a case, the known from the prior art and described above methods for the assignment of operating addresses used, it means that the luminaire must identify several times in the context of address allocation to the central control unit and then each an operating address receives. This is associated with a not inconsiderable amount of time. More serious, however, is the problem that with such a procedure for the headquarters is not readily apparent that several of the assigned operating addresses each belong to a particular lamp. An efficient control, in particular a coordinated control of the various units of a lamp, however, is only possible if the central control unit actually has knowledge of the relationship between the assigned operating addresses with the individual units of the lamp.
    The present invention is based on the object to offer a solution to this problem. In particular, the address allocation for such more complex lights should be simplified or optimized and at the same time ensure that the central control unit is aware of which operating addresses have been assigned to the light.
    The object is achieved by a method for starting up a lighting system according to claim 1 and by a control unit for a lighting system according to claim 6. Advantageous developments of the invention are the subject of the dependent claims.
    The solution according to the invention is based on the idea of enabling the control unit of the system to recognize in the context of the address assignment whether a luminaire is present which requires a plurality of operating addresses. If this is the case, then the central control unit interrupts the usual procedure for assigning the operating addresses to the participants of the system and instead transmits directly first the number of operating addresses still needed to the light. Not only does this result in faster address assignment because the luminaire no longer has to identify itself to the central control unit several times. In addition, it is also ensured that the central control unit is immediately aware of how many and which operating addresses have been assigned to the luminaire. This ensures that, at a later point in time, an efficient activation of the luminaire within the framework of the illumination system can take place.
    According to the invention therefore a method for commissioning a lighting system for a plurality of distributed lights is proposed, wherein the lights - are preferably connected via a bus system - with a central control unit and this is adapted to contact the lights after identification and give them an operating address to convey. According to the invention, the control unit is designed to recognize, in the context of the assignment of a first operating address to a luminaire, which requires a plurality of operating addresses, that it is such a more complex luminaire. In this case, all further operating addresses are then transmitted to this luminaire directly by the central control unit, before an address is assigned to further luminaires of the system.
    The recognition of the fact that it is a lamp that requires multiple operating addresses, can be done by reading the so-called. GTIN information (GTIN: General Trade Identification Number). According to the DALI standard, which is the preferred example of application for the present invention, this GTIN information contains an indication of what kind of DALI device it is. According to the present invention, this information now not only includes the fact that the luminaire requires several operating addresses, but also contains the information about the number of addresses required. As already mentioned, this information requires the central control unit, on the one hand, to actually transmit the further required addresses to the luminaire within the scope of the method according to the invention. At the same time then within the central control unit is also the information about which operating addresses together the control of the lamp takes place, so that thereby an integration of the lamp is made possible in the system.
    It is not mandatory that it is the successive address of the DALI system in the assigned to the lamp operating addresses, even if this would of course be advantageous. For the central control unit, however, it is primarily relevant to the information which operating addresses have been assigned to the lights. A corresponding assignment of these addresses, for example, then to the individual light units of the luminaire can then take place in a suitable manner by the central control unit.
    Finally, the present invention thus opens up the possibility of integrating even more complex luminaires in a simple and efficient manner into a lighting system, in particular into a lighting system which operates in accordance with the DALI standard.
    The invention will be explained in more detail with reference to the accompanying drawings. FIGS. 1 to 5 are views of a luminaire with a plurality of mutually separated steuerba ren lighting modules; Figure 6 is a schematic representation of a lighting system according to the invention; 7 shows a diagram of the method according to the invention for address assignment, and FIG. 8 shows the extract of a memory area of the control unit of the luminaire.
    Reference to the figures 1 to 5, a luminaire will first be explained, in which the inventive method for address assignment is used in a particularly advantageous manner. Of course, the invention is by no means limited to this illustrated concrete embodiment of a lamp, but can always be used when a lamp has a plurality of separately controllable units for light output.
    Shown here is initially in Figures 1 and 2 in two different views a generally provided with the reference numeral 100 luminaire, which is formed in the illustrated embodiment as a pendant light and at least one suspension element, in the present case two ropes 101 on a not shown carrier element, for example. Is attached to the ceiling of a room. In the same way, however, the luminaire 100 could also be used as a ceiling-mounted luminaire.
    As can be seen in the figures, the lamp 100 is running a total of elongated. Their shape is determined in the first place by a support member 102, which represents the central element of the lamp 100 and on which all other components are arranged or attached. The carrier element 102 has on its underside or the Lichtabstrahl side of the lamp 100 has a cross-sectionally approximately U-shaped receiving area in which a plurality of lighting modules are arranged interchangeable.
    Two views of such a light module are shown in Figures 4 and 5, wherein Figure 4 is a perspective view of the light module from the top and Figure 5 shows the bottom, over which the light is emitted. As can be seen, the lighting module 110 is approximately box-shaped and has on its rear side 111 - not shown - means for mechanical attachment to the support member 102 and means for electrical contacting of power supply and control lines. In particular, these contacting means are formed by a plug 112, which is coupled when inserting the module 110 in the receiving area of the support member 102 with corresponding mating connector elements of the lamp 100 and thus connected to a control unit of the lamp 100. In the inserted state, therefore, the lighting module 110 is not only mechanically fastened to the carrier element 102, but also electrically connected to the control unit of the luminaire 100. This opens up the possibility for the control unit of the luminaire 100 to supply power to the module 110 and to control it individually in order, for example, to adjust the brightness of the light output.
    For the light output a plurality of - not shown LEDs are arranged within the module 110. These LEDs are arranged like a matrix, wherein the light output in the illustrated embodiment takes place in two different ways. As can be seen from the view of the module 110 from below in accordance with FIG. 5, several lenses 115 are arranged in a 3 × 6 matrix in the more central area. Each lens is assigned an LED, so that the corresponding light is then emitted via the associated lens 115 directed towards the bottom. Thus, for example, intensive and targeted illumination of a workstation or other object is achieved via this light output. In the peripheral region of this LED lens matrix is a frame-like additional area 116, which is also associated with LEDs. This frame region 116 is designed in such a way that light emitted via it is emitted rather diffusely. Ultimately, this means that the module 110 emits light in two different ways, on the one hand in the form of a directed light emission via the lenses 115 and on the other hand diffuse over the surrounding frame 116.
    As already mentioned, a plurality of such modules 110 are arranged in the receiving region of the carrier element 102, so that a view of the luminaire 100 results from the underside, as shown in FIG. It can be seen, therefore, that in the exemplary embodiment shown, a total of 14 lighting modules 110 are used, which are configured identically in principle, but in principle can each be individually controlled. Strictly speaking, it would be conceivable that in the control of the individual modules 110 again between the light sources for the directed light output and the light sources for the diffuse
    Light output is distinguished. In this case, 28 (14 × 2) independent of each other in their light output adjustable LED groups or units would be in terms of a light output to the bottom of the lamp 100 down. To simplify the following explanations, it should be assumed, however, that there is no separation between directional and diffuse light emission. Furthermore, it should also possibly, additional bulbs that are used, for example, for an indirect light output to the top, are not taken into account. In this simplified case there are therefore 14 taxable units.
    If in fact all 14 lighting modules are controlled independently, it would be necessary to assign the lamp 100 a total of 14 DALI addresses.
    E in a corresponding illumination system is shown in Figure 6, wherein here as a preferred embodiment, a DALI system 50 is shown, which has a central control unit 51, from which extends the bus line 52 of the system 50. As an alternative to the illustration, wireless communication would of course also be conceivable. On these bus lines u.a. the lamp 100 is connected, which internally has a control unit 120, which is provided for communication with the central control information 51. Thus, DALI commands issued by this control unit 51 are implemented by the control unit 120, such that the individual modules 110 are operated with the desired brightness. The manner in which the control unit 120 causes the individual modules 110 to assume the desired brightness plays a minor role in the present invention. It could, for example, be provided that each module 110 is supplied individually by the control unit 120 with an already correspondingly designed current. It would also be conceivable, however, that the control unit 120 only outputs brightness commands to the modules 110, which in turn automatically assume a corresponding brightness.
    So if the central control unit 51 of the system are enabled to specify a brightness setpoint for each individual module 110, then each module would have its own DALI operating address assigned. That is, even in the present simplified case, in which there is no distinction between directional and diffuse light output and dispense with a separate control of indirect lighting, the allocation of a total of 14 DALI addresses would be required, but this is rather unrealistic, since in this case then maximum four such lights 100 could ever be connected to the system 50. Realistically, therefore, the number of DALI addresses used by the luminaire 100 will be reduced, in which case, for example, some neighboring modules will be similarly driven under a certain address, or the brightness values will be preset by the DALI brightness setpoints at certain positions of the lighting modules 110 and those in between lying modules assume a brightness that corresponds to a particular brightness gradient or brightness profile. Realistically about four to eight DALI addresses for the luminaire 100 would then be used in the present case.
    In this case too, however, it must be ensured that, on the one hand, the allocation of the DALI addresses takes place efficiently and, on the other hand, after the addresses have been assigned, the central control unit 51 knows which of the assigned DALI addresses belong together to the luminaire 100. This problem is solved with the aid of the procedure according to the invention, which will now be explained in more detail below.
    The sequence of the address allocation according to the invention is shown schematically in FIG. The basic principle of the method corresponds to the known from the prior art procedures for the assignment of operating addresses, for example, according to the DALI standard. That is, after initialization of the system, the central control unit makes contact with a single connected load, that is, one of the lights connected to the system. This first step S1 can be realized in a variety of ways, wherein, as mentioned above, for example, it would be conceivable to identify all the connected lights on the basis of a unique address and the central control unit selects and contacts one of the lights. This individual address may, for example, be a factory-assigned source address or a random address. The choice of a single luminaire can also be made in different variants, with one possibility being to select, after an identification request by the central control unit, the luminaire which is the first to register. Alternatively, all addresses could first be collected and then treated in ascending or descending order.
    After contact has been made with a single luminaire, the next step is to assign the operating address to the corresponding luminaire (step S2). There are also different approaches from the prior art for this purpose, with an example being that the luminaire is contacted using the source or random address and requested to emit a recognizable luminance signal, ie to turn on, for example. As a result, the position of the luminaire in a building or a room can be detected and, accordingly, the central control unit can be made to assign an operating address which takes this position into consideration. The address is then stored in a memory of the luminaire or the operating device of the luminaire.
    In the previous methods of the prior art, these two steps 51 and S2 were repeated until all lights had received an operating address. In the event that a light required multiple addresses, so was a so-called. Multi-address light, this had then several times participate in steps S1 and S2.
    According to the solution according to the invention, however, it is now provided that initially takes place after assignment of the operating address in step 2 in the subsequent step S3, a check whether the just contacted light represents a multi-address light, so is a light that several DALI Addresses needed. As mentioned above, this can be done, for example, by assigning the first operating address to this luminaire the central control unit from the memory of the luminaire control unit 120 to read the so-called GTIN information (GTIN: General Trade Identification Number) which characterizes the luminaire. This data not only provides information about whether it is actually a multi-address light, but also how many addresses the light needs in total.
    An excerpt from the memory contents of a luminaire is shown schematically in FIG. Initially, the already mentioned GTIN information is stored in a first area 201 of the memory 200. Further memory locations 202 to 205 contain the DALI addresses, in the present case it being assumed that the luminaire requires four DALI addresses, as already mentioned. For the sake of simplicity, the address assigned to the luminaire in step S2 is written into the first memory location 202, since-as will be seen below-the luminaire performs contact with the central control unit only once within the framework of the regular address assignment.
    If the check in step S3 negative, so it is a simple lamp that requires only a single DALI address, the method is continued with step S1, although now the already supplied with DALI addresses lights no longer participate. That is, of the remaining lights that still need addresses, in turn makes contact with the central control unit and receives in the subsequent step 52, a corresponding operating address. As already mentioned, this corresponds to the usual procedure according to the prior art.
    However, if it is indeed a multi-address light, the contact with this light is maintained and the central control unit awards in step S4 immediately another operating address to this light. This is then written to the next free address storage location of the operating device of the luminaire.
    If it is determined in the following step S5 then that the memory locations for the operating addresses have not been completely filled, then another address is given, this loop is repeated until the check in step S5 positive, so the light actually the required number of operating addresses has been assigned, which have been successively written into the address memory locations 202 to 205.
    Thus, the lamp is completely powered and the process is continued with step 1 with the remaining lights, now also the multi-address light no longer participates in the process, as is known in the prior art.
    For the check in step 5, whether the light has received all addresses, the central control unit could count independently, since it knows how many addresses are needed due to the information obtained in step S3, or directly to the address memory area 202nd access to 205 and check if it is already completely filled.
    It can be seen that in this approach according to the invention the lamp is very easily and quickly assigned the required number of required operating addresses. The address assignment is significantly accelerated because the multi-address lights only need to contact the central control unit once. However, another decisive advantage lies in the fact that it is immediately apparent to the central control unit that steps S4 and S5 have each been carried out with the lamp to which contact was made in step S1. In other words, in the case of the central control unit, information is already available as to which operating addresses are shared by a specific luminaire. This considerably simplifies the generation of the brightness setpoint values required by the central control unit for later operation. This may ideally be at the assigned operating addresses to successive addresses, but this is not mandatory.
    Thus, the method according to the invention represents a significant advance over previously used solutions. As already mentioned, the advantages come into play, in particular in a DALI system, but the invention is by no means limited to this particular communication standard but can of course also be applied other standards are used.
