Definitions

  • the present invention relates to a method for putting a lighting system into operation, operating addresses being assigned to the luminaires of the system as part of the method.
  • Lighting systems of modern design which are intended in particular for lighting larger buildings or systems, usually offer the option of switching the lights arranged in different areas on or off or adjusting their brightness not only via the switches or dimmers arranged in the respective areas . Instead, there is also the option of remotely controlling the lights from a central control device. This achieves convenient lighting control for illuminating larger buildings or complexes.
  • Lighting systems of this type therefore usually have one or more command transmitters, which can use commands to address and control the lamp operating devices that are arranged decentrally in different areas and are connected to a power supply network. Communication from the lamp operating devices to the command generator is also often provided in order, for example, to report back faulty operating states. In this way, not only convenient lighting control but also reliable monitoring of the status of the lighting system is made possible.
  • the individual lamp operating devices are controlled via an address which is individually assigned to them and via which they can be addressed by the central control unit.
  • the lamp operating devices are preferably 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.
  • DALI Digital Addressable Lighting Interface
  • This is an interface developed by the lighting industry for the transmission of digital control commands between a central control unit and distributed consumers. Up to 64 lights can then be connected to one via a so-called DALI bus command devices can be connected, which lights can be individually addressed. Since the corresponding lamp operating devices do not yet have an operating address when they are manufactured and installed in the lighting system, this must be assigned as part of an initialization procedure that is to be carried out in accordance with the DALI standard as explained below.
  • the operating devices of the individual lights are first connected to the DALI bus, i.e. the control line.
  • the subsequent supply of voltage to the lamp operating devices causes each lamp operating device to generate an individual random address for itself.
  • the command is then issued from the central command generator for the lamp operating devices to report with their random address, as a result of which a list of all devices is created internally at the command generator, which also contains the information about which random addresses the devices can be contacted in each case.
  • this random address does not yet take into account the spatial arrangement of the lamp operating device and is unsuitably long for ongoing operation, in a subsequent step the devices are then assigned the operating address provided for subsequent operation.
  • the central command generator first calls up a first random address, with the result that the corresponding lamp is identified, ie, for example, lights up. Now a person has to determine in which room this lamp is located. As soon as the position has been determined, a corresponding feedback is sent to the control center. Another person then enters the location and the group of the luminaire that is reporting into the control unit, with the result that this luminaire is then assigned a suitable operating address. All random addresses are processed in this way one after the other until all lights have been assigned an operating address. This is stored in a corresponding memory of the lamp operating device.
  • each lamp has a single operating address under which it is controlled by the central control unit of the system.
  • lights are also known from the prior art which have several separate units for light emission, the brightness and/or color or color temperature of which can be adjusted independently of one another. In the simplest case, these are, for example, lights that have lighting means for direct light emission on the one hand and lighting means for indirect light emission on the other.
  • Lights are also known which have individual light modules which are arranged, for example, in an elongated arrangement one behind the other or in the manner of a matrix and can each be set individually with regard to their light output.
  • the luminaire is then usually assigned a plurality of operating addresses, which are then used to transmit individual brightness setpoint values for the individual units or at least groups of units. In this case, several operating addresses must be assigned to the light.
  • the U.S. 2012/133303 A1 describes a method for putting several lights into operation, it being possible to use identification information to determine whether the light requires several operating addresses.
  • the DE 10 2010 020960 A1 describes an arrangement and a method in which a lamp can send information to a receiver by means of luminous flux, the receiver being able to read this luminous flux and evaluate the information contained therein.
  • the object of the present invention is to offer a solution to this problem.
  • the allocation of addresses for such more complex lights should be simplified or optimized and at the same time it should be ensured that the central control unit has knowledge of which operating addresses have been allocated to the light.
  • the object is achieved by a method for putting a lighting system into operation according to claim 1 and by a control unit for a lighting system
  • the solution according to the invention is based on the idea of enabling the control unit of the system to recognize, within the scope of the address assignment, whether there is a lamp which requires several operating addresses. If this is the case, the central control unit interrupts the usual procedure for allocating the operating addresses to the participants in the system and instead first immediately transmits the number of operating addresses still required to the lamp. This not only means that addresses are assigned more quickly, since 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 has direct knowledge of how many and which operating addresses have been assigned to the light. This ensures that the lamp can actually be controlled efficiently as part of the lighting system at a later point in time.
  • a method for starting up a lighting system for a number of distributed lights is therefore proposed, the lights being connected to a central control unit—preferably via a bus system—and this being designed to contact the lights after they have been identified and to transmit an operating address to them.
  • the control unit is designed to recognize when a first operating address is assigned to a light that requires a number of operating addresses that it is a more complex light of this type. In this case, all other operating addresses are then immediately transmitted to this light by the central control unit before addresses are assigned to other lights in the system, with the check as to whether the contacted light requires several operating addresses by reading out and evaluating one in a memory of the light stored GTIN information, which contains the information on the number of addresses required.
  • this GTIN information contains a statement about what kind of DALI device it is. According to the present invention, this information now contains not only the fact that the lamp requires several operating addresses, but also contains information about the number of addresses required. On the one hand, the central control unit needs this information - as already mentioned - in order to actually be able to method according to the invention then to transmit the addresses that are still required immediately to the lamp. At the same time, the central control unit also contains the information about which operating addresses are used to jointly control the lamp, so that the lamp can be integrated into the system as a result.
  • the operating addresses assigned to the light it is not absolutely necessary for the operating addresses assigned to the light to be consecutive addresses of the DALI system, even if this would of course be advantageous.
  • the central control unit the information as to which operating addresses have been assigned to the lights is primarily relevant. A corresponding assignment of these addresses, for example to the individual lighting units of the lamp, can then be carried out in a suitable manner by the central control unit.
  • the present invention thus opens up the possibility of also integrating more complex lights in a simple and efficient manner into a lighting system, in particular into a lighting system which operates in accordance with the DALI standard.
  • a lamp generally provided with the reference numeral 100, which is designed as a pendant lamp in the illustrated embodiment and is attached via at least one suspension element, in the present case via two cables 101 to a support element, not shown, e.g. on the ceiling of a room.
  • the lamp 100 could also be used as a surface-mounted ceiling lamp.
  • the luminaire 100 is elongate overall. Its shape is primarily determined by a carrier element 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 light emission side of the lamp 100 a receiving area that is approximately U-shaped in cross section, in which several light modules are arranged in an exchangeable manner.
  • FIG. 4 Two views of such a light module are in the Figures 4 and 5 shown where figure 4 a perspective view of the lighting module from the top and figure 5 the underside over which the light is emitted shows.
  • the lighting module 110 is approximately box-shaped and has on its rear side 111 - not shown - means for mechanical attachment to the carrier element 102 and means for electrical contacting of power supply and control lines.
  • these contacting means are formed by a plug 112 which, when the module 110 is inserted into the receiving area of the carrier element 102 , is coupled to corresponding mating plug elements of the lamp 100 and thus connected to a control unit of the lamp 100 .
  • the lighting module 110 is not only mechanically attached to the carrier element 102 but is also electrically connected to the control unit of the lamp 100 .
  • this opens up the possibility of supplying the module 110 with power and controlling it individually, for example in order to adjust the brightness of the light output.
  • LEDs are arranged within the module 110 for light emission. These LEDs are arranged in a matrix, with the light emission taking place in two different ways in the exemplary embodiment shown. Namely, as according to the view of the module 110 from below figure 5 As can be seen, a plurality of lenses 115 are arranged in a 3 ⁇ 6 matrix in the more central area. An LED is assigned to each lens, so that the corresponding light is then emitted via the assigned lens 115 towards the underside. For example, this light emission is used to achieve intensive and targeted illumination of a workplace or another object. In the peripheral area of this LED lens matrix there is a frame-like additional area 116, which is also assigned LEDs.
  • This frame area 116 is designed in such a way that light emitted via it is radiated 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 diffusely via the surrounding frame 116.
  • a plurality of such modules 110 are arranged in the receiving area of the carrier element 102, so that the luminaire 100 is viewed from the underside as shown in FIG figure 3 is shown.
  • a total of 14 light modules 110 are used in the illustrated exemplary embodiment, which in principle are configured identically, but can in principle each be controlled individually. Strictly speaking, it would be conceivable that when the individual modules 110 are controlled, a distinction is again made between the light sources for the directed light emission and the light sources for the diffuse light emission. In this case, there would be as many as 28 (14 ⁇ 2) LED groups or units whose light output could be adjusted independently of one another with regard to light emission towards the underside of the lamp 100 .
  • a corresponding lighting system is in figure 6 shown, a DALI system 50 being shown here as a preferred exemplary embodiment, which has a central control unit 51, from which the bus line 52 of the system 50 extends.
  • the lamp 100 is connected to these bus lines, among other things, and has a control unit 120 internally, which is provided for communication with the central control information 51 . DALI commands issued by this control unit 51 are thus implemented by the control unit 120 in such a way that the individual modules 110 are operated with the desired brightness.
  • control unit 120 causes the individual modules 110 to assume the desired brightness plays a subordinate role for the present invention. Provision could be made, for example, for each module 110 to be supplied individually by the control unit 120 with a current that has already been designed accordingly. However, it would also be conceivable for the control unit 120 to only output brightness commands to the modules 110, which in turn then automatically assume a corresponding brightness.
  • each module would have to be assigned its own DALI operating address. This means that even in the simplified case presented here, in which no distinction is made between directed and diffuse light emission and separate control of indirect lighting is dispensed with, it would be necessary to allocate a total of 14 DALI addresses, which is rather unrealistic, as in this case the maximum four such lights 100 could be connected to the system 50 at all.
  • the number of DALI addresses used by the light 100 will therefore realistically be reduced, in which case, for example, some neighboring modules will be controlled in the same way under a specific address, or the brightness values will be specified by the DALI brightness setpoints at specific positions of the light modules 110 and the The modules in between assume a brightness that corresponds to a specific brightness progression or brightness profile. Realistically, around four to eight DALI addresses would then be used for the light 100 in the present case.

  • This individual address can be, for example, a factory-assigned original address or a random address.
  • the selection of an individual lamp can also take place in different variants, one possibility being, after an identification request by the central control unit, to select that lamp which reports first.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Inbetriebnahme eines Beleuchtungssystems, wobei im Rahmen des Verfahrens den Leuchten des Systems Betriebsadressen zugewiesen werden.The present invention relates to a method for putting a lighting system into operation, operating addresses being assigned to the luminaires of the system as part of the method.

Beleuchtungssysteme moderner Bauart, welche insbesondere zur Beleuchtung größerer Gebäude oder Anlagen vorgesehen sind, bieten in der Regel die Option, die in unterschiedlichen Bereichen angeordneten Leuchten nicht nur über die in den jeweiligen Bereichen angeordneten Schalter oder Dimmer ein- oder auszuschalten bzw. in ihrer Helligkeit einzustellen. Stattdessen besteht auch die Möglichkeit, die Leuchten von einer zentralen Steuereinrichtung aus fernzusteuern. Hierdurch wird eine komfortable Beleuchtungssteuerung zur Ausleuchtung größerer Gebäude oder Komplexe erzielt. Derartige Beleuchtungssysteme weisen deshalb üblicherweise einen oder mehrere Befehlsgeber auf, welche die dezentralen in unterschiedlichen Bereichen angeordneten und an ein Stromversorgungsnetz angeschlossenen Lampenbetriebsgeräte über Befehle ansprechen und steuern können. Oftmals ist auch eine Kommunikation von den Lampenbetriebsgeräten zu dem Befehlsgeber hin vorgesehen, um bspw. fehlerhafte Betriebszustände zurückzumelden. Auf diese Weise wird nicht nur eine komfortable Beleuchtungssteuerung sondern auch eine zuverlässige Überwachung des Zustands des Beleuchtungssystems ermöglicht.Lighting systems of modern design, which are intended in particular for lighting larger buildings or systems, usually offer the option of switching the lights arranged in different areas on or off or adjusting their brightness not only via the switches or dimmers arranged in the respective areas . Instead, there is also the option of remotely controlling the lights from a central control device. This achieves convenient lighting control for illuminating larger buildings or complexes. Lighting systems of this type therefore usually have one or more command transmitters, which can use commands to address and control the lamp operating devices that are arranged decentrally in different areas and are connected to a power supply network. Communication from the lamp operating devices to the command generator is also often provided in order, for example, to report back faulty operating states. In this way, not only convenient lighting control but also reliable monitoring of the status of the lighting system is made possible.

Die Ansteuerung der einzelnen Lampenbetriebsgeräte erfolgt über eine ihnen individuell zugeordnete Adresse, über die sie von der zentralen Steuereinheit angesprochen werden können. Vorzugsweise werden dabei den Lampenbetriebsgeräten sog. Betriebsadressen zugewiesen, welche unter anderem auch die Anordnung der Lichtquellen in den unterschiedlichen Bereichen des auszuleuchtenden Gebäudes berücksichtigen. Hierbei besteht ergänzend auch die Möglichkeit, die in den verschiedenen Räumen angeordneten Lichtquellen in Gruppen zusammenzufassen, welche gemeinsam von der zentralen Steuereinheit angesprochen werden können.The individual lamp operating devices are controlled via an address which is individually assigned to them and via which they can be addressed by the central control unit. In this case, the lamp operating devices are preferably 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, there is also the possibility of combining the light sources arranged in the various rooms into groups which can be addressed jointly by the central control unit.

Steuerungssysteme für Lampenbetriebsgeräte, welche eine individuelle Ansteuerung der Geräte ermöglichen, arbeiten heutzutage oftmals gemäß dem sog. DALI (Digital Adressable Lighting Interface) Standard. Hierbei handelt es sich um eine von der Beleuchtungsindustrie entwickelte Schnittstelle zur Übermittlung von digitalen Steuerbefehlen zwischen einer zentralen Steuereinheit und verteilt angeordneten Verbrauchern. Über einen sog. DALI-Bus können dann bis zu 64 Leuchten an einen Befehlsgeber angeschlossen werden, welche Leuchten individuell adressierbar sind. Da die entsprechenden Lampenbetriebsgeräte bei ihrer Herstellung und Montage in dem Beleuchtungssystem noch keine Betriebsadresse aufweisen, muss diese im Rahmen einer Initialisierungsprozedur vergeben werden, die gemäß dem DALI-Standard wie nachfolgend erläutert durchzuführen ist.Control systems for lamp operating devices, which enable individual control of the devices, often work nowadays in accordance with 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. Up to 64 lights can then be connected to one via a so-called DALI bus command devices can be connected, which lights can be individually addressed. Since the corresponding lamp operating devices do not yet have an operating address when they are manufactured and installed in the lighting system, this must be assigned as part of an initialization procedure that is to be carried out in accordance with the DALI standard as explained below.

Nach Montage aller Lampenbetriebsgeräte ohne Ansehung ihrer räumlichen Anordnung werden die Betriebsgeräte der einzelnen Leuchten zunächst an den DALI-Bus, also die Steuerleitung angeschlossen. Die daraufhin erfolgende Versorgung der Lampenbetriebsgeräte mit Spannung bewirkt, dass jedes Lampenbetriebsgerät für sich eine individuelle Zufallsadresse generiert. Von dem zentralen Befehlsgeber aus wird dann der Befehl erteilt, dass sich die Lampenbetriebsgeräte mit ihrer Zufallsadresse melden, wodurch intern bei dem Befehlsgeber eine Liste sämtlicher Geräte angelegt wird, welche auch die Information enthält, über welche Zufallsadressen die Geräte jeweils kontaktierbar sind.After all of the lamp operating devices have been installed without considering their spatial arrangement, the operating devices of the individual lights are first connected to the DALI bus, i.e. the control line. The subsequent supply of voltage to the lamp operating devices causes each lamp operating device to generate an individual random address for itself. The command is then issued from the central command generator for the lamp operating devices to report with their random address, as a result of which a list of all devices is created internally at the command generator, which also contains the information about which random addresses the devices can be contacted in each case.

Da diese Zufallsadresse allerdings noch nicht die räumliche Anordnung des Lampenbetriebsgeräts berücksichtigt und für den laufenden Betrieb ungeeignet lang ist, wird in einem darauf folgenden Schritt den Geräten dann jeweils die für den späteren Betrieb vorgesehene Betriebsadresse zugewiesen. Dies erfolgt dadurch, dass der zentrale Befehlsgeber zunächst eine erste Zufallsadresse aufruft, was zur Folge hat, dass sich die entsprechende Leuchte identifiziert, also bspw. aufleuchtet. Nunmehr muss eine Person feststellen, in welchem Raum sich diese Leuchte befindet. Sobald die Position festgestellt wurde, erfolgt eine entsprechende Rückmeldung an die Zentrale. Eine weitere Person gibt dann den Platz und die Gruppe der sich meldenden Leuchte in das Steuergerät ein, was zur Folge hat, dass dieser Leuchte dann eine geeignete Betriebsadresse zugewiesen wird. Nacheinander werden auf diese Weise sämtliche Zufallsadressen abgehandelt, bis sämtlichen Leuchten eine Betriebsadresse zugewiesen wurde. Diese wird jeweils in einem entsprechenden Speicher des Lampenbetriebsgeräts abgelegt.However, since this random address does not yet take into account the spatial arrangement of the lamp operating device and is unsuitably long for ongoing operation, in a subsequent step the devices are then assigned the operating address provided for subsequent operation. This is done in that the central command generator first calls up a first random address, with the result that the corresponding lamp is identified, ie, for example, lights up. Now a person has to determine in which room this lamp is located. As soon as the position has been determined, a corresponding feedback is sent to the control center. Another person then enters the location and the group of the luminaire that is reporting into the control unit, with the result that this luminaire is then assigned a suitable operating address. All random addresses are processed in this way one after the other until all lights have been assigned an operating address. This is stored in a corresponding memory of the lamp operating device.

Bei den obigen Ausführungen wurde davon ausgegangen, dass jede Leuchte eine einzige Betriebsadresse aufweist, unter der sie von der zentralen Steuereinheit des Systems angesteuert wird. Aus dem Stand der Technik sind zwischenzeitlich allerdings auch Leuchten bekannt, welche mehrere getrennte Einheiten zur Lichtabgabe aufweisen, die voneinander unabhängig in ihrer Helligkeit und/oder Farbe bzw. Farbtemperatur eingestellt werden können. Im einfachsten Fall handelt es sich bspw. um Leuchten, welche einerseits Leuchtmittel für eine direkte Lichtabgabe und andererseits Leuchtmittel für eine indirekte Lichtabgabe aufweisen. Allerdings sind darüber hinaus auch Leuchten bekannt, bei denen die direkte Lichtabgabe nochmals weiter unterteilt ist, bspw. in einen stark gerichteten Anteil, der dann bspw. zur Beleuchtung von Arbeitsplätzen oder gezielten Beleuchtung von Objekten genutzt wird, sowie einen eher diffusen Lichtanteil, über den eine großflächige aber weniger intensive Zusatz- bzw. Hintergrundbeleuchtung geschaffen wird. Auch sind Leuchten bekannt, welche einzelne Leuchtmodule aufweisen, die bspw. in einer länglichen Anordnung hintereinander oder matrixartig angeordnet sind und jeweils individuell hinsichtlich ihrer Lichtabgabe eingestellt werden können.In the above statements, it was assumed that each lamp has a single operating address under which it is controlled by the central control unit of the system. In the meantime, however, lights are also known from the prior art which have several separate units for light emission, the brightness and/or color or color temperature of which can be adjusted independently of one another. In the simplest case, these are, for example, lights that have lighting means for direct light emission on the one hand and lighting means for indirect light emission on the other. However are Also known are lights in which the direct light emission is further subdivided, e.g. into a strongly directional component, which is then used, for example, to illuminate workplaces or the targeted illumination of objects, and a more diffuse light component, over which a large area but less intense additional or background lighting is created. Lights are also known which have individual light modules which are arranged, for example, in an elongated arrangement one behind the other or in the manner of a matrix and can each be set individually with regard to their light output.

Bei diesen komplexeren Leuchten ist es in der Regel nicht ausreichend, wenn die Ansteuerung nur mit einer einzigen Betriebsadresse erfolgt, da dann die vielfältigen Möglichkeiten zur Lichtabgabe nicht oder nur unzureichend genutzt werden könnten. Üblicherweise werden deshalb der Leuchte dann mehrere Betriebsadressen zugewiesen, unter deren Verwendung dann jeweils individuell Helligkeitssollwerte für die einzelnen Einheiten oder zumindest Gruppen von Einheiten übermittelt werden. In diesem Fall müssen dann an die Leuchte also mehrere Betriebsadressen vergeben werden.In the case of these more complex lights, it is usually not sufficient if the control is only carried out with a single operating address, since then the diverse options for light emission could not be used or only insufficiently. For this reason, the luminaire is then usually assigned a plurality of operating addresses, which are then used to transmit individual brightness setpoint values for the individual units or at least groups of units. In this case, several operating addresses must be assigned to the light.

Kommen in einem derartigen Fall die aus dem Stand der Technik bekannten und oben beschriebenen Verfahren zur Vergabe von Betriebsadressen zum Einsatz, so bedeutet dies, dass sich die Leuchte im Rahmen der Adressvergabe mehrmals gegenüber der zentralen Steuereinheit identifizieren muss und dann jeweils eine Betriebsadresse erhält. Dies ist mit einem nicht unbeträchtlichen Zeitaufwand verbunden. Gravierender ist allerdings das Problem, dass bei einer derartigen Vorgehensweise für die Zentrale nicht ohne Weiteres erkennbar ist, dass mehrere der vergebenen Betriebsadressen jeweils zu einer bestimmten Leuchte gehören. Eine effiziente Ansteuerung, insbesondere eine aufeinander abgestimmte Ansteuerung der verschiedenen Einheiten einer Leuchte ist allerdings nur dann möglich, wenn die zentrale Steuereinheit tatsächlich Kenntnis davon hat, in welchem Zusammenhang die vergebenen Betriebsadressen mit den einzelnen Einheiten der Leuchte stehen.If the methods known from the prior art and described above for assigning operating addresses are used in such a case, this means that the luminaire must identify itself to the central control unit several times as part of the address assignment and then receive an operating address in each case. This is associated with a not inconsiderable expenditure of time. More serious, however, is the problem that with such a procedure, the control center cannot readily recognize that several of the assigned operating addresses each belong to a specific lamp. However, efficient control, in particular coordinated control of the various units of a lamp, is only possible if the central control unit actually has knowledge of the connection between the allocated operating addresses and the individual units of the lamp.

Anspruch 5 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Claim 5 solved. Advantageous developments of the invention are the subject matter of the dependent claims.

Die erfindungsgemäße Lösung beruht auf dem Gedanken, die Steuereinheit des Systems in die Lage zu versetzen, im Rahmen der Adressvergabe zu erkennen, ob eine Leuchte vorliegt, welche mehrere Betriebsadressen benötigt. Ist dies der Fall, so unterbricht die zentrale Steuereinheit die übliche Prozedur zum Vergeben der Betriebsadressen an die Teilnehmer des Systems und übermittelt stattdessen zunächst unmittelbar die Anzahl der noch benötigten Betriebsadressen an die Leuchte. Dies führt nicht nur dazu, dass die Adressvergabe schneller erfolgt, da sich die Leuchte nicht mehr mehrmals gegenüber der zentralen Steuereinheit identifizieren muss. Darüber hinaus ist auch sichergestellt, dass die zentrale Steuereinheit unmittelbar Kenntnis darüber erlangt, wie viele und welche Betriebsadressen an die Leuchte vergeben wurden. Hierdurch ist sichergestellt, dass zu einem späteren Zeitpunkt tatsächlich eine effiziente Ansteuerung der Leuchte im Rahmen des Beleuchtungssystems erfolgen kann.The solution according to the invention is based on the idea of enabling the control unit of the system to recognize, within the scope of the address assignment, whether there is a lamp which requires several operating addresses. If this is the case, the central control unit interrupts the usual procedure for allocating the operating addresses to the participants in the system and instead first immediately transmits the number of operating addresses still required to the lamp. This not only means that addresses are assigned more quickly, since 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 has direct knowledge of how many and which operating addresses have been assigned to the light. This ensures that the lamp can actually be controlled efficiently as part of the lighting system at a later point in time.

Erfindungsgemäß wird deshalb ein Verfahren zur Inbetriebnahme eines Beleuchtungssystems für mehrere verteilt angeordnete Leuchten vorgeschlagen, wobei die Leuchten - vorzugsweise über ein Bussystem - mit einer zentralen Steuereinheit verbunden sind und diese dazu ausgebildet ist, die Leuchten nach Identifizierung zu kontaktieren und ihnen eine Betriebsadresse zu übermitteln. Erfindungsgemäß ist dabei die Steuereinheit dazu ausgebildet, im Rahmen der Vergabe einer ersten Betriebsadresse an eine Leuchte, die mehrere Betriebsadressen benötigt, zu erkennen, dass es sich um eine derartige komplexere Leuchte handelt. In diesem Fall werden dann durch die zentrale Steuereinheit unmittelbar alle weiteren Betriebsadressen an diese Leuchte übermittelt, bevor eine Adressvergabe an weitere Leuchten des Systems erfolgt, wobei die Überprüfung, ob die kontaktierte Leuchte mehrere Betriebsadressen benötigt, durch Auslesen und Bewerten einer in einem Speicher der Leuchte gespeicherten GTIN-Information, welche die Information, wie hoch die Anzahl der benötigten Adressen ist, enthält, erfolgt.According to the invention, a method for starting up a lighting system for a number of distributed lights is therefore proposed, the lights being connected to a central control unit—preferably via a bus system—and this being designed to contact the lights after they have been identified and to transmit an operating address to them. According to the invention, the control unit is designed to recognize when a first operating address is assigned to a light that requires a number of operating addresses that it is a more complex light of this type. In this case, all other operating addresses are then immediately transmitted to this light by the central control unit before addresses are assigned to other lights in the system, with the check as to whether the contacted light requires several operating addresses by reading out and evaluating one in a memory of the light stored GTIN information, which contains the information on the number of addresses required.

Gemäß dem DALI-Standard, der das bevorzugte Anwendungsbeispiel für die vorliegende Erfindung darstellt, enthält diese GTIN-Information eine Aussage darüber, um was für ein DALI-Gerät es sich handelt. Gemäß der vorliegenden Erfindung beinhaltet nunmehr diese Information nicht nur die Tatsache, dass die Leuchte mehrere Betriebsadressen benötigt, sondern enthält darüber hinaus auch die Information, wie hoch die Anzahl der benötigten Adressen ist. Diese Information benötigt - wie bereits erwähnt - die zentrale Steuereinheit einerseits, um tatsächlich im Rahmen des erfindungsgemäßen Verfahrens dann der Leuchte unmittelbar die weiterhin benötigten Adressen zu übermitteln. Gleichzeitig liegt dann innerhalb der zentralen Steuereinheit auch die Information darüber vor, über welche Betriebsadressen gemeinsam die Ansteuerung der Leuchte erfolgt, so dass hierdurch eine Einbindung der Leuchte in das System ermöglicht wird.According to the DALI standard, which represents the preferred application example for the present invention, this GTIN information contains a statement about what kind of DALI device it is. According to the present invention, this information now contains not only the fact that the lamp requires several operating addresses, but also contains information about the number of addresses required. On the one hand, the central control unit needs this information - as already mentioned - in order to actually be able to method according to the invention then to transmit the addresses that are still required immediately to the lamp. At the same time, the central control unit also contains the information about which operating addresses are used to jointly control the lamp, so that the lamp can be integrated into the system as a result.

Es ist hierbei nicht zwingend erforderlich, dass es sich bei den an die Leuchte vergebenen Betriebsadressen um aufeinanderfolgende Adresse des DALI-Systems handelt, auch wenn dies selbstverständlich vorteilhaft wäre. Für die zentrale Steuereinheit ist allerdings in erster Linie die Information relevant, welche Betriebsadressen an die Leuchten vergeben wurden. Eine entsprechende Zuordnung dieser Adressen bspw. dann zu den einzelnen Leuchteinheiten der Leuchte kann dann durch die zentrale Steuereinheit in geeigneter Weise erfolgen.In this case, it is not absolutely necessary for the operating addresses assigned to the light to be consecutive addresses of the DALI system, even if this would of course be advantageous. For the central control unit, however, the information as to which operating addresses have been assigned to the lights is primarily relevant. A corresponding assignment of these addresses, for example to the individual lighting units of the lamp, can then be carried out in a suitable manner by the central control unit.

Letztendlich eröffnet die vorliegende Erfindung also die Möglichkeit, auch komplexere Leuchten in einfacher und effizienter Weise in ein Beleuchtungssystem, insbesondere in ein Beleuchtungssystem, welches entsprechend dem DALI-Standard arbeitet, einzubinden.Ultimately, the present invention thus opens up the possibility of also integrating more complex lights in a simple and efficient manner into a lighting system, in particular into a lighting system which operates in accordance with the DALI standard.

Anhand der Figuren 1 bis 5 soll zunächst eine Leuchte erläutert werden, bei der in besonders vorteilhafter Weise das erfindungsgemäße Verfahren zur Adressvergabe zum Einsatz kommt. Selbstverständlich ist allerdings die Erfindung keinesfalls auf diese dargestellte konkrete Ausführungsform einer Leuchte beschränkt, sondern kann immer dann zum Einsatz kommen, wenn eine Leuchte mehrere getrennt voneinander steuerbare Einheiten zur Lichtabgabe aufweist.Based on Figures 1 to 5 a lamp will first be explained in which the method according to the invention for assigning addresses is used in a particularly advantageous manner. Of course, however, the invention is in no way limited to this specific embodiment of a lamp shown, but can are always used when a lamp has several separately controllable units for light emission.

Dargestellt ist dabei zunächst in den Figuren 1 und 2 in zwei unterschiedlichen Ansichten eine allgemein mit dem Bezugszeichen 100 versehene Leuchte, welche im dargestellten Ausführungsbeispiel als Pendelleuchte ausgebildet ist und über wenigstens ein Aufhängelement, im vorliegenden Fall über zwei Seile 101 an einem nicht dargestellten Trägerelement, bspw. an der Decke eines Raums befestigt wird. In gleicher Weise könnte die Leuchte 100 allerdings auch als Deckenanbauleuchte genutzt werden.Shown is first in the Figures 1 and 2 in two different views, a lamp generally provided with the reference numeral 100, which is designed as a pendant lamp in the illustrated embodiment and is attached via at least one suspension element, in the present case via two cables 101 to a support element, not shown, e.g. on the ceiling of a room. In the same way, however, the lamp 100 could also be used as a surface-mounted ceiling lamp.

Wie in den Figuren erkennbar ist, ist die Leuchte 100 insgesamt länglich ausgeführt. Ihre Form wird hierbei in erster Linie durch ein Trägerelement 102 festgelegt, welches das zentrale Element der Leuchte 100 darstellt und an dem alle weiteren Komponenten angeordnet bzw. befestigt sind. Das Trägerelement 102 weist dabei an seiner Unterseite bzw. der Lichtabstrahlseite der Leuchte 100 einen im Querschnitt etwa U-förmigen Aufnahmebereich auf, in dem mehrere Leuchtmodule auswechselbar angeordnet werden.As can be seen in the figures, the luminaire 100 is elongate overall. Its shape is primarily determined by a carrier element 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 light emission side of the lamp 100 a receiving area that is approximately U-shaped in cross section, in which several light modules are arranged in an exchangeable manner.

Zwei Ansichten eines derartigen Leuchtmoduls sind in den Figuren 4 und 5 gezeigt, wobei Figur 4 eine perspektivische Ansicht des Leuchtmoduls von der Oberseite her und Figur 5 die Unterseite, über welche das Licht abgegeben wird, zeigt. Wie erkennbar ist, ist das Leuchtmodul 110 etwa kastenförmig ausgebildet und weist an seiner Rückseite 111 - nicht näher dargestellte - Mittel zur mechanischen Befestigung an dem Trägerelement 102 sowie Mittel zur elektrischen Kontaktierung von Stromversorgungs- und Steuerleitungen auf. Insbesondere diese Kontaktierungsmittel werden durch einen Stecker 112 gebildet, der beim Einsetzen des Moduls 110 in den Aufnahmebereich des Trägerelements 102 mit entsprechenden Gegensteckerelementen der Leuchte 100 gekoppelt und damit mit einer Steuereinheit der Leuchte 100 verbunden wird. Im eingesetzten Zustand ist also das Leuchtmodul 110 nicht nur mechanisch an dem Trägerelement 102 befestigt, sondern auch elektrisch mit der Steuereinheit der Leuchte 100 verbunden. Dies eröffnet für die Steuereinheit der Leuchte 100 die Möglichkeit, das Modul 110 mit Strom zu versorgen sowie individuell anzusteuern, um beispielsweise die Helligkeit der Lichtabgabe einzustellen.Two views of such a light module are in the Figures 4 and 5 shown where figure 4 a perspective view of the lighting module from the top and figure 5 the underside over which the light is emitted shows. 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 carrier element 102 and means for electrical contacting of power supply and control lines. In particular, these contacting means are formed by a plug 112 which, when the module 110 is inserted into the receiving area of the carrier element 102 , is coupled to corresponding mating plug elements of the lamp 100 and thus connected to a control unit of the lamp 100 . In the inserted state, the lighting module 110 is not only mechanically attached to the carrier element 102 but is also electrically connected to the control unit of the lamp 100 . For the control unit of the lamp 100, this opens up the possibility of supplying the module 110 with power and controlling it individually, for example in order to adjust the brightness of the light output.

Für die Lichtabgabe sind innerhalb des Moduls 110 mehrere - nicht näher dargestellte - LEDs angeordnet. Diese LEDs sind matrixartig angeordnet, wobei die Lichtabgabe beim dargestellten Ausführungsbeispiel auf zwei verschiedene Arten erfolgt. Wie nämlich der Ansicht des Moduls 110 von unten gemäß Figur 5 entnommen werden kann, sind im zentraleren Bereich mehrere Linsen 115 in einer 3x6-Matrix angeordnet. Jeder Linse ist dabei eine LED zugeordnet, so dass das entsprechende Licht dann über die zugeordnete Linse 115 gerichtet zur Unterseite hin abgestrahlt wird. Über diese Lichtabgabe wird also bspw. eine intensive und gezielte Beleuchtung eines Arbeitsplatzes oder eines anderen Objekts erzielt. Im Umfangsbereich dieser LED-Linsen-Matrix befindet sich ein rahmenartiger zusätzlicher Bereich 116, dem ebenfalls LEDs zugeordnet sind. Dieser Rahmenbereich 116 ist dabei derart ausgeführt, dass über ihn abgegebenes Licht eher diffus abgestrahlt wird. Letztendlich bedeutet dies, dass das Modul 110 in zwei verschiedenen Arten Licht abgibt, einerseits in Form einer gerichteten Lichtabgabe über die Linsen 115 sowie andererseits diffus über den umlaufenden Rahmen 116.Several LEDs—not shown in detail—are arranged within the module 110 for light emission. These LEDs are arranged in a matrix, with the light emission taking place in two different ways in the exemplary embodiment shown. Namely, as according to the view of the module 110 from below figure 5 As can be seen, a plurality of lenses 115 are arranged in a 3×6 matrix in the more central area. An LED is assigned to each lens, so that the corresponding light is then emitted via the assigned lens 115 towards the underside. For example, this light emission is used to achieve intensive and targeted illumination of a workplace or another object. In the peripheral area of this LED lens matrix there is a frame-like additional area 116, which is also assigned LEDs. This frame area 116 is designed in such a way that light emitted via it is radiated 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 diffusely via the surrounding frame 116.

Wie bereits erwähnt, sind in dem Aufnahmebereich des Trägerelements 102 mehrere derartige Module 110 angeordnet, sodass sich von der Unterseite her eine Ansicht der Leuchte 100 ergibt, wie sie in Figur 3 gezeigt ist. Erkennbar ist also, dass im dargestellten Ausführungsbeispiel insgesamt 14 Leuchtmodule 110 zum Einsatz kommen, welche im Prinzip identisch ausgestaltet sind, aber grundsätzlich jeweils individuell angesteuert werden können. Genaugenommen wäre es denkbar, dass bei der Ansteuerung der einzelnen Module 110 nochmals zwischen den Lichtquellen für die gerichtete Lichtabgabe sowie den Lichtquellen für die diffuse Lichtabgabe unterschieden wird. In diesem Fall würden also im Hinblick auf eine Lichtabgabe zur Unterseite der Leuchte 100 hin sogar 28 (14 x 2) unabhängig voneinander in ihrer Lichtabgabe einstellbare LED-Gruppen bzw. Einheiten vorliegen. Zur Vereinfachung der nachfolgenden Erläuterungen soll allerdings davon ausgegangen werden, dass keine Trennung zwischen gerichteter und diffuser Lichtabgabe vorliegt. Ferner sollen auch evtl. zusätzliche Leuchtmittel, die beispielsweise für eine indirekte Lichtabgabe zur Oberseite hin genutzt werden, nicht berücksichtigt werden. In diesem vereinfachten Fall liegen also 14 steuerbare Einheiten vor.As already mentioned, a plurality of such modules 110 are arranged in the receiving area of the carrier element 102, so that the luminaire 100 is viewed from the underside as shown in FIG figure 3 is shown. It can thus be seen that a total of 14 light modules 110 are used in the illustrated exemplary embodiment, which in principle are configured identically, but can in principle each be controlled individually. Strictly speaking, it would be conceivable that when the individual modules 110 are controlled, a distinction is again made between the light sources for the directed light emission and the light sources for the diffuse light emission. In this case, there would be as many as 28 (14×2) LED groups or units whose light output could be adjusted independently of one another with regard to light emission towards the underside of the lamp 100 . To simplify the following explanations, however, it should be assumed that there is no separation between directed and diffuse light emission. Furthermore, any additional light sources that are used, for example, for indirect light emission towards the top should also not be taken into account. In this simplified case there are 14 controllable units.

Sollten tatsächlich alle 14 Leuchtmodule unabhängig voneinander angesteuert werden, so wäre es erforderlich, der Leuchte 100 insgesamt 14 DALI-Adressen zuzuweisen. Ein entsprechendes Beleuchtungssystem ist in Figur 6 dargestellt, wobei hier als bevorzugtes Ausführungsbeispiel ein DALI-System 50 gezeigt ist, welches eine zentrale Steuereinheit 51 aufweist, von der sich ausgehend die Busleitung 52 des Systems 50 erstreckt. Alternativ zu der Darstellung wäre selbstverständlich auch eine drahtlose Kommunikation denkbar. An diese Busleitungen ist u.a. die Leuchte 100 angeschlossen, welche intern eine Steuereinheit 120 aufweist, die für die Kommunikation mit der zentralen Steuerinformation 51 vorgesehen ist. Von dieser Steuereinheit 51 ausgegebene DALI-Befehle werden also von der Steuereinheit 120 umgesetzt, derart, dass die einzelnen Module 110 mit der gewünschten Helligkeit betrieben werden. In welcher Art und Weise hierbei die Steuereinheit 120 die einzelnen Module 110 veranlasst, die gewünschte Helligkeit anzunehmen, spielt für die vorliegende Erfindung eine untergeordnete Rolle. Es könnte bspw. vorgesehen sein, dass jedes Modul 110 individuell von der Steuereinheit 120 mit einem bereits entsprechend ausgelegten Strom versorgt wird. Denkbar wäre allerdings auch, dass die Steuereinheit 120 lediglich Helligkeitsbefehle an die Module 110 ausgibt, die dann wiederum selbstständig eine entsprechende Helligkeit annehmen.Should all 14 light modules actually be controlled independently of one another, it would be necessary to assign the light 100 a total of 14 DALI addresses. A corresponding lighting system is in figure 6 shown, a DALI system 50 being shown here as a preferred exemplary embodiment, which has a central control unit 51, from which the bus line 52 of the system 50 extends. As an alternative to the illustration, wireless communication would of course also be conceivable. The lamp 100 is connected to these bus lines, among other things, and has a control unit 120 internally, which is provided for communication with the central control information 51 . DALI commands issued by this control unit 51 are thus implemented by the control unit 120 in such a way 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 subordinate role for the present invention. Provision could be made, for example, for each module 110 to be supplied individually by the control unit 120 with a current that has already been designed accordingly. However, it would also be conceivable for the control unit 120 to only output brightness commands to the modules 110, which in turn then automatically assume a corresponding brightness.

Soll also die zentrale Steuereinheit 51 des Systems in die Lage versetzt werden, für jedes einzelne Modul 110 einen Helligkeitssollwert vorzugeben, so müsste jedem Modul eine eigene DALI-Betriebsadresse zugewiesen werden. D.h., bereits im vorliegenden vereinfachten Fall, in dem nicht zwischen gerichteter und diffuser Lichtabgabe unterschieden und auf eine separate Ansteuerung einer Indirektbeleuchtung verzichtet wird, wäre die Vergabe von insgesamt 14 DALI-Adressen erforderlich, was jedoch eher unrealistisch ist, da in diesem Fall dann maximal vier derartiger Leuchten 100 überhaupt an das System 50 angeschlossen werden könnten. Realistischer Weise wird deshalb die Anzahl der von der Leuchte 100 genutzten DALI-Adressen reduziert werden, wobei dann bspw. einige benachbarte Module unter einer bestimmten Adresse gleichartig angesteuert werden oder durch die DALI-Helligkeitssollwerte an bestimmten Positionen der Leuchtmodule 110 die Helligkeitswerte vorgegeben werden und die dazwischen liegenden Module eine Helligkeit annehmen, die einem bestimmten Helligkeits-Verlauf oder Helligkeits-Profil entspricht. Realistisch würden im vorliegenden Fall dann etwa vier bis acht DALI-Adressen für die Leuchte 100 genutzt werden.If the central control unit 51 of the system is to be able to specify a desired brightness value for each individual module 110, each module would have to be assigned its own DALI operating address. This means that even in the simplified case presented here, in which no distinction is made between directed and diffuse light emission and separate control of indirect lighting is dispensed with, it would be necessary to allocate a total of 14 DALI addresses, which is rather unrealistic, as in this case the maximum four such lights 100 could be connected to the system 50 at all. The number of DALI addresses used by the light 100 will therefore realistically be reduced, in which case, for example, some neighboring modules will be controlled in the same way under a specific address, or the brightness values will be specified by the DALI brightness setpoints at specific positions of the light modules 110 and the The modules in between assume a brightness that corresponds to a specific brightness progression or brightness profile. Realistically, around four to eight DALI addresses would then be used for the light 100 in the present case.

Auch in diesem Fall muss allerdings sichergestellt werden, dass einerseits die Vergabe der DALI-Adressen effizient erfolgt und andererseits nach Vergabe der Adressen die zentrale Steuereinheit 51 weiß, welche der vergebenen DALI-Adressen gemeinsam zu der Leuchte 100 gehören. Diese Problemstellung wird mit Hilfe der erfindungsgemäßen Vorgehensweise gelöst, welche nachfolgend nun näher erläutert werden soll.In this case too, however, it must be ensured that, on the one hand, the DALI addresses are assigned efficiently and, on the other hand, after the addresses have been assigned, the central control unit 51 knows which of the assigned DALI addresses is shared belonging to the luminaire 100. This problem is solved with the help of the procedure according to the invention, which will now be explained in more detail below.

Der Ablauf der erfindungsgemäßen Adressvergabe ist schematisch in Figur 7 dargestellt. Das Grundprinzip des Verfahrens entspricht dabei den aus dem Stand der Technik bekannten Vorgehensweisen zur Vergabe von Betriebsadressen bspw. entsprechend dem DALI-Standard. D.h., nach Beginn der Initialisierung des Systems nimmt die zentrale Steuereinheit Kontakt mit einem einzelnen angeschlossenen Verbraucher, also einer der an das System angeschlossenen Leuchten auf. Dieser erste Schritt S1 kann in vielfältiger Weise realisiert werden, wobei wie eingangs erwähnt bspw. denkbar wäre, dass sich alle angeschlossenen Leuchten anhand einer eindeutigen Adresse identifizieren und die zentrale Steuereinheit eine der Leuchten auswählt und kontaktiert. Bei dieser individuellen Adresse kann es sich bspw. um eine werksseitig vergebene Ursprungsadresse oder um eine Zufallsadresse handeln. Das Auswählen einer einzelnen Leuchte kann ebenfalls in verschiedenen Varianten erfolgen, wobei eine Möglichkeit darin besteht, nach einer Identifizierungsaufforderung durch die zentrale Steuereinheit diejenige Leuchte auszuwählen, die sich als Erste meldet. Alternativ hierzu könnten auch alle Adressen erst gesammelt und dann in aufsteigender oder absteigender Reihenfolge behandelt werden.The procedure for assigning addresses according to the invention is shown schematically in figure 7 shown. The basic principle of the method corresponds to the procedures known from the prior art for assigning operating addresses, for example according to the DALI standard. This means that after the initialization of the system has started, the central control unit makes contact with an individual connected load, ie one of the lights connected to the system. This first step S1 can be implemented in a variety of ways, it being conceivable, for example, as mentioned at the outset, for all connected lights to identify themselves using a unique address and for the central control unit to select and contact one of the lights. This individual address can be, for example, a factory-assigned original address or a random address. The selection of an individual lamp can also take place in different variants, one possibility being, after an identification request by the central control unit, to select that lamp which reports first. Alternatively, all addresses could be collected first and then treated in ascending or descending order.

Nach erfolgter Kontaktaufnahme mit einer einzelnen Leuchte erfolgt dann im nächsten Schritt die Vergabe der Betriebsadresse an die entsprechende Leuchte (Schritt S2). Auch hierfür existieren verschiedene Vorgehensweisen aus dem Stand der Technik, wobei eine bspw. darin besteht, dass die Leuchte unter Nutzung der Ursprungs- oder Zufallsadresse kontaktiert und dazu aufgefordert wird, ein erkennbares Helligkeitssignal abzugeben, sich also bspw. einzuschalten. Hierdurch kann die Position der Leuchte in einem Gebäude oder einem Raum erkannt und dementsprechend die zentrale Steuereinheit dazu veranlasst werden, eine diese Position berücksichtigende Betriebsadresse zu vergeben. Die Adresse wird dann in einem Speicher der Leuchte bzw. des Betriebsgeräts der Leuchte hinterlegt.After contact has been made with an individual lamp, the next step is to assign the operating address to the corresponding lamp (step S2). Here, too, there are various procedures from the prior art, one of which is, for example, that the lamp is contacted using the original or random address and is requested to emit a recognizable brightness signal, ie to switch itself on, for example. As a result, the position of the lamp in a building or a room can be detected and the central control unit can accordingly be prompted to allocate an operating address that takes this position into account. The address is then stored in a memory of the light or the operating device of the light.

Bei den bisherigen Verfahren aus dem Stand der Technik wurden diese beiden Schritte S1 und S2 nun solange wiederholt, bis alle Leuchten eine Betriebsadresse erhalten hatten. Für den Fall, dass eine Leuchte mehrere Adressen benötigte, also eine sog. Multi-Adress-Leuchte war, musste diese dann mehrfach an den Schritten S1 und S2 teilnehmen.In the previous methods from the prior art, these two steps S1 and S2 were now repeated until all the lights had received an operating address. In the event that a lamp required several addresses, i.e. was a so-called multi-address lamp, it then had to take part in steps S1 and S2 several times.

Gemäß der erfindungsgemäßen Lösung ist nun allerdings vorgesehen, dass zunächst nach Vergabe der Betriebsadresse in Schritt 2 im darauffolgenden Schritt S3 eine Prüfung stattfindet, ob die gerade kontaktierte Leuchte eine Multi-Adress-Leuchte darstellt, also eine Leuchte ist, die mehrere DALI-Adressen benötigt. Wie oben erwähnt, kann dies bspw. dadurch erfolgen, dass bei Vergabe der ersten Betriebsadresse an diese Leuchte die zentrale Steuereinheit aus dem Speicher der Leuchtensteuereinheit 120 die sog. GTIN-Information (GTIN: General Trade Identification Number) ausliest, welche die Leuchte charakterisiert. Diese Daten geben nicht nur darüber Auskunft, ob es sich tatsächlich um eine Multi-Adress-Leuchte handelt, sondern auch, wie viele Adressen die Leuchte insgesamt benötigt.According to the solution according to the invention, however, it is now provided that after the assignment of the operating address in step 2, in the subsequent step S3, a check takes place as to whether the light just contacted is a multi-address light, i.e. a light that requires multiple DALI addresses . As mentioned above, this can be done, for example, by the central control unit reading the so-called GTIN information (GTIN: General Trade Identification Number), which characterizes the lamp, from the memory of the lamp control unit 120 when the first operating address is assigned to this lamp. This data not only provides information as to whether it is actually a multi-address luminaire, but also how many addresses the luminaire requires in total.

Ein Auszug aus dem Speicherinhalt einer Leuchte ist schematisch in Figur 8 dargestellt. Dabei ist zunächst in einem ersten Bereich 201 des Speichers 200 die bereits erwähnte GTIN-Information gespeichert. Weitere Speicherplätze 202 bis 205 beinhalten die DALI-Adressen, wobei im vorliegenden Fall davon ausgegangen wird, dass die Leuchte wie bereits erwähnt vier DALI-Adressen benötigt. Der Einfachheit halber wird die in Schritt S2 an die Leuchte vergebene Adresse in den ersten Speicherplatz 202 eingeschrieben, da - wie nachfolgend ersichtlich ist - im Rahmen der regulären Adressvergabe die Leuchte nur einmal eine Kontaktaufnahme mit der zentralen Steuereinheit durchführt.An excerpt from the memory content of a lamp is shown schematically in figure 8 shown. In this case, the already mentioned GTIN information is initially stored in a first area 201 of the memory 200 . Further memory locations 202 to 205 contain the DALI addresses, it being assumed in the present case that the light, as already mentioned, requires four DALI addresses. For the sake of simplicity, the address assigned to the lamp in step S2 is written into the first memory location 202, since—as will be seen below—the lamp only makes contact with the central control unit once as part of the regular address assignment.

Fällt die Überprüfung in Schritt S3 negativ aus, handelt es sich also um eine einfache Leuchte, die lediglich eine einzige DALI-Adresse benötigt, so wird das Verfahren mit Schritt S1 fortgeführt, wobei nunmehr allerdings die bereits mit DALI-Adressen versorgten Leuchten nicht mehr teilnehmen. D.h., von den verbleibenden Leuchten, die noch Adressen benötigen, nimmt wiederum eine Kontakt mit der zentralen Steuereinheit auf und erhält im darauffolgenden Schritt S2 eine entsprechende Betriebsadresse. Dies entspricht wie bereits erwähnt der üblichen Vorgehensweise gemäß dem Stand der Technik.If the check in step S3 is negative, ie it is a simple lamp that only requires a single DALI address, the method is continued with step S1, although the lamps that are already supplied with DALI addresses are no longer involved . In other words, one of the remaining lights that still needs addresses makes contact with the central control unit and receives a corresponding operating address in the subsequent step S2. As already mentioned, this corresponds to the usual procedure according to the prior art.

Handelt es sich allerdings tatsächlich um eine Multi-Adress-Leuchte, so wird die Kontaktaufnahme mit dieser Leuchte beibehalten und die zentrale Steuereinheit vergibt in Schritt S4 unmittelbar eine weitere Betriebsadresse an diese Leuchte. Diese wird dann in den nächsten freien Adress-Speicherplatz des Betriebsgeräts der Leuchte eingeschrieben.However, if it is actually a multi-address lamp, contact with this lamp is maintained and the central control unit immediately assigns a further operating address to this lamp in step S4. This is then written to the next free address memory location of the lamp's control gear.

Wird im darauffolgenden Schritt S5 dann festgestellt, dass die Speicherplätze für die Betriebsadressen noch nicht vollständig aufgefüllt wurden, so wird eine weitere Adresse vergeben, wobei diese Schleife solange wiederholt wird, bis die Überprüfung in Schritt S5 positiv ausfällt, also der Leuchte tatsächlich die geforderte Anzahl an Betriebsadressen zugewiesen wurde, welche sukzessive in die Adress-Speicherplätze 202 bis 205 eingeschrieben wurden. Damit ist die Leuchte vollständig versorgt und das Verfahren wird mit Schritt 1 mit den verbleibenden Leuchten fortgeführt, wobei nunmehr auch die Multi-Adress-Leuchte nicht mehr an dem Verfahren teilnimmt, wie dies aus dem Stand der Technik bekannt ist.If it is determined in the subsequent step S5 that the memory locations for the operating addresses have not yet been completely filled, then a further address is assigned, with this loop being repeated until the check is made in step S5 is positive, i.e. the lamp has actually been assigned the required number of operating addresses, which have been successively written into the address memory locations 202 to 205. The lamp is thus fully supplied and the method is continued with step 1 with the remaining lamps, with the multi-address lamp now also no longer participating in the method, as is known from the prior art.

Für die Überprüfung in Schritt 5, ob die Leuchte alle Adressen erhalten hat, könnte die zentrale Steuereinheit selbständig mitzählen, da sie aufgrund der in Schritt S3 erhaltenen Information weiß, wie viele Adressen benötigt werden, oder unmittelbar auf den Adress-Speicherbereich 202 bis 205 zugreifen und überprüfen, ob dieser bereits vollständig gefüllt ist.To check in step 5 whether the lamp has received all addresses, the central control unit could count independently, since it knows how many addresses are required based on the information received in step S3, or directly access the address memory area 202 to 205 and check whether it is already completely filled.

Es ist ersichtlich, dass bei dieser erfindungsgemäßen Vorgehensweise der Leuchte sehr einfach und schnell die benötigte Anzahl der erforderlichen Betriebsadressen zugewiesen wird. Dabei wird die Adressvergabe deutlich beschleunigt, da die Multi-Adress-Leuchten lediglich ein einziges Mal mit der zentralen Steuereinheit Kontakt aufnehmen müssen. Ein weiterer entscheidender Vorteil liegt allerdings auch darin, dass für die zentrale Steuereinheit unmittelbar ersichtlich ist, dass die Schritte S4 und S5 jeweils mit derjenigen Leuchte durchgeführt wurden, zu der in Schritt S1 Kontakt aufgenommen wurde. D.h., bei der zentralen Steuereinheit liegt bereits die Information vor, welche Betriebsadressen gemeinsam durch eine bestimmte Leuchte genutzt werden. Dies vereinfacht wesentlich die für den späteren Betrieb erforderliche Generierung der Helligkeitssollwerte durch die zentrale Steuereinheit. Dabei kann es sich idealerweise bei den vergebenen Betriebsadressen um aufeinanderfolgende Adressen handeln, dies ist jedoch nicht zwingend erforderlich.It can be seen that with this procedure according to the invention, the required number of required operating addresses is assigned to the lamp very easily and quickly. Address assignment is significantly accelerated, since the multi-address lights only have to contact the central control unit once. However, a further decisive advantage lies in the fact that it is immediately apparent to the central control unit that steps S4 and S5 were each carried out with that lamp which was contacted in step S1. This means that the central control unit already has the information about which operating addresses are used jointly by a specific luminaire. This significantly simplifies the generation of the desired brightness values by the central control unit, which is required for later operation. Ideally, the assigned operating addresses can be consecutive addresses, but this is not absolutely necessary.

Das erfindungsgemäße Verfahren stellt also einen deutlichen Fortschritt gegenüber bislang zum Einsatz kommenden Lösungen dar. Wie bereits erwähnt, kommen die Vorteile insbesondere in einem DALI-System zum Tragen, allerdings ist die Erfindung keinesfalls auf diesen speziellen Kommunikationsstandard beschränkt sondern kann selbstverständlich auch bei anderen Standards zum Einsatz kommen.The method according to the invention therefore represents a significant advance over solutions used to date. As already mentioned, the advantages come into play in particular in a DALI system, but the invention is in no way limited to this special communication standard but can of course also be used with other standards come into action.
