Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Beleuchtungsanlage mittels eines Datenkonverters gemäß dem Oberbegriff des Patentanspruchs 1 und einen entsprechenden Datenkonverter.The invention relates to a method for operating a lighting system by means of a data converter according to the preamble of patent claim 1 and a corresponding data converter.

I. Stand der Technik I. State of the art

Die Offenlegungsschrift WO 02/41671 A2 beschreibt eine Beleuchtungsanlage mit mehreren Lampenbetriebsmitteln und einer zentralen Steuervorrichtung für die Lampenbetriebsmittel, wobei die Lampenbetriebsmittel über adressierbare Schnittstellen verfügen, über die digitale Daten mit der zentralen Steuervorrichtung kommuniziert werden. Diese Kommunikation erfolgt gemäß des standardisierten sogenannten DALI-Protokolls. Die Abkürzung DALI steht für Digital Addressable Lighting Interface.The Publication WO 02/41671 A2 describes a lighting system with a plurality of lamp resources and a central control device for the lamp resources, wherein the lamp operating means have addressable interfaces, are communicated via the digital data with the central control device. This communication takes place in accordance with the standardized so-called DALI protocol. The abbreviation DALI stands for Digital Addressable Lighting Interface.

Die Offenlegungsschrift US 2003/0036807 A1 offenbart eine Beleuchtungsanlage mit Leuchten, die von einer Vielzahl unterschiedlicher Orte und über eine digital adressierbare Schnittstelle kontrollierbar sind.The publication US 2003/0036807 A1 discloses a lighting system with lights that are controllable from a variety of different locations and via a digital addressable interface.

Die Offenlegungsschrift WO 03/077610 A1 beschreibt ein Initialisierungsverfahren für ein drahtlos kontrolliertes Beleuchtungssystem.The publication WO 03/077610 A1 describes an initialization method for a wireless controlled lighting system.

Ein Nachteil der Beleuchtungsanlagen, deren zentrale Steuervorrichtungen gemäß des DALI-Protokolls mit den Lampenbetriebsmitteln kommunizieren ist, dass ihr Adressenvorrat auf vierundsechzig individuelle Adressen und sechzehn Gruppenadressen beschränkt ist. Außerdem beträgt die maximale Strombelastbarkeit der Schnittstelle der zentralen Steuervorrichtung nur 250 mA. Dadurch wird die maximale Anzahl der an die zentrale Steuervorrichtung anschließbaren Lampenbetriebsmittel entsprechend begrenzt.A disadvantage of the lighting systems whose central control devices communicate with the lamp resources according to the DALI protocol is that their address memory is limited to sixty-four individual addresses and sixteen group addresses. In addition, the maximum current carrying capacity of the interface of the central control device is only 250 mA. Thereby, the maximum number of connectable to the central control device lamp resources is limited accordingly.

II. Darstellung der Erfindung II. Presentation of the invention

Es ist die Aufgabe der Erfindung, ein Verfahren und eine entsprechende Vorrichtung bereitzustellen, welche den oben genannten Nachteil der Steuervorrichtungen von Beleuchtungsanlagen, die gemäß des DALI-Protokolls mit den Lampenbetriebsmitteln kommunizieren, vermeiden.It is the object of the invention to provide a method and a corresponding device which avoid the above-mentioned disadvantage of the control devices of lighting systems which communicate with the lamp operating means according to the DALI protocol.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Patentansprüchen beschrieben.This object is achieved by the features of claim 1. Particularly advantageous embodiments of the invention are described in the dependent claims.

Die erfindungsgemäße Vorrichtung, die hier als Datenkonverter bezeichnet wird, besitzt einen Dateneingang zur Kommunikation des Datenkonverters mit einer zentralen Steuervorrichtung der Beleuchtungsanlage, einen Datenausgang zur Kommunikation des Datenkonverters mit Lampenbetriebsmitteln und eine Auswertungseinheit zur Auswertung der von der zentralen Steuervorrichtung empfangenen Daten und zur Steuerung sowie Überwachung der Funktionen der Lampenbetriebsmittel. Bei den Lampenbetriebsmitteln handelt es sich beispielsweise um Elektronische Vorschaltgeräte für Niederdruck- oder Hochdruckentladungslampen, Transformatoren zum Betrieb von Niedervolt-Halogenglühlampen oder um Treiberschaltungen für Leuchtdioden. Der Begriff Lampen wird im folgenden stellvertretend für alle Arten von elektrisch betriebenen Leuchtmitteln verwendet.The device according to the invention, which is referred to here as a data converter, has a data input for communication of the data converter with a central control device of the lighting system, a data output for communication of the data converter with lamp resources and an evaluation unit for evaluating the data received from the central control device and for control and monitoring the functions of the lamp resources. The lamp resources are, for example, electronic ballasts for low-pressure or high-pressure discharge lamps, transformers for the operation of low-voltage halogen incandescent lamps or driver circuits for light-emitting diodes. The term lamps is used in the following representative of all types of electrically operated bulbs.

Über seinen Dateneingang kann der erfindungsgemäße Datenkonverter von der zentralen Steuervorrichtung auf die gleiche Weise wie ein Lampenbetriebsmittel gesteuert werden. Das heißt insbesondere, dass der erfindungsgemäße Datenkonverter von der zentralen Steuervorrichtung mit denselben Steuersignalen wie die unmittelbar von der zentralen Steuervorrichtung kontrollierten Lampenbetriebsmittel beaufschlagt werden kann. Die Auswertungseinheit des Datenkonverters wandelt diese Steuersignale der zentralen Steuervorrichtung in Kommandos zur Steuerung der von dem Datenkonverter kontrollierten Lampenbetriebsmittel um. Der erfindungsgemäße Datenkonverter verhält sich gegenüber der zentralen Steuervorrichtung hinsichtlich Adressierung und Steuerung wie ein einzelnes Lampenbetriebsmittel. Andererseits ist aber der Datenausgang des erfindungsgemäßen Datenkonverters derart ausgebildet, dass über diesen Datenausgang an viele Lampenbetriebsmittel Kommandos zur Steuerung und Überwachung ihrer Funktionen weitergegeben werden können, wobei diese Kommandos von der Auswertungseinheit des erfindungsgemäßen Datenkonverters in Abhängigkeit von den Steuersignalen der zentralen Steuervorrichtung generiert werden. Dadurch kann die Anzahl der Lampenbetriebsmittel in der Beleuchtungsanlage, deren Funktion mittels der zentralen Steuervorrichtung kontrollierbar ist, vergrößert werden. Der maximal zulässige Schnittstellenstrom der zentralen Steuervorrichtung wird nicht überschritten, da sich der erfindungsgemäße Datenkonverter gegenüber der zentralen Steuervorrichtung wie ein Lampenbetriebsmittel verhält und an seinem Datenausgang den Schnittstellenstrom für die von dem Datenkonverter kontrollierten Lampenbetriebsmittel selbst bereitstellt.Via its data input, the data converter according to the invention can be controlled by the central control device in the same way as a lamp operating means. This means, in particular, that the data converter according to the invention can be acted upon by the central control device with the same control signals as the lamp operating means controlled directly by the central control device. The evaluation unit of the data converter converts these control signals of the central control device into commands for controlling the lamp operating means controlled by the data converter. The data converter according to the invention behaves in relation to the central control device Addressing and control as a single lamp resource. On the other hand, however, the data output of the data converter according to the invention is designed in such a way that commands for controlling and monitoring its functions can be transmitted via this data output to many lamp resources, these commands being generated by the evaluation unit of the data converter according to the invention as a function of the control signals of the central control device. This allows the number of lamp resources in the lighting system, whose function is controllable by means of the central control device can be increased. The maximum permissible interface current of the central control device is not exceeded since the data converter according to the invention behaves like a lamp operating medium relative to the central control device and provides the interface current for the lamp operating means controlled by the data converter itself at its data output.

Um die Speicherung eines von der zentralen Steuervorrichtung zugewiesenen Adresscodes in dem Datenkonverter zu ermöglichen, weist der Datenkonverter vorteilhafter Weise ein nicht-flüchtiges Speichermittel auf. Der Dateneingang des Datenkonverters ist vorzugsweise als multifunktionaler Eingang ausgebildet, der sowohl digitale als auch analoge Steuersignale empfangen kann, die von der Auswertungseinheit des Datenkonverters in Kommandos für die von ihm kontrollierten Lampenbetriebsmittel umgewandelt werden, wie es beispielsweise in der Offenlegungsschrift WO 01/52607 A1 beschrieben wurde. Dadurch ist der erfindungsgemäße Datenkonverter nicht nur kompatibel mit einer zentralen Steuervorrichtung, die gemäß des standardisierten DALI-Protokolls kommuniziert, sondern es kann sich bei der zentralen Steuervorrichtung im einfachsten Fall sogar um einen Taster handeln.In order to enable the storage of an address code assigned by the central control device in the data converter, the data converter advantageously has a non-volatile storage means. The data input of the data converter is preferably designed as a multifunctional input, which can receive both digital and analog control signals, which are converted by the evaluation unit of the data converter into commands for the controlled by him lamp resources, as for example in the published patent application WO 01/52607 A1 has been described. As a result, the data converter according to the invention is not only compatible with a central control device which communicates according to the standardized DALI protocol, but in the simplest case the central control device can even be a push button.

Um den erfindungsgemäßen Datenkonverter möglichst universell verwenden zu können, ist zwischen mindestens zwei unterschiedlichen Betriebsmodi umschaltbar ausgebildet.In order to use the data converter according to the invention as universally as possible, is formed switchable between at least two different operating modes.

Gemäß dem erfindungsgemäßen Verfahren zum Betreiben einer Beleuchtungsanlage, die mehrere Lampenbetriebsmittel und eine zentrale Steuervorrichtung für die Lampenbetriebsmittel aufweist, werden wenigstens einige Lampenbetriebsmittel mittels eines Datenkonverters kontrolliert und gesteuert, der die von der zentralen Steuervorrichtung generierten Steuersignale empfängt, auswertet und in Abhängigkeit von dem Ergebnis der Auswertung in Kommandos zur Steuerung der von dem Datenkonverter kontrollierten Lampenbetriebsmittel umwandelt. Wie bereits oben erwähnt wurde, kann dadurch die Anzahl der Lampenbetriebsmittel in der Beleuchtungsanlage, deren Funktion mittels der zentralen Steuervorrichtung kontrollierbar ist, vergrößert werden.According to the inventive method of operating a lighting system comprising a plurality of lamp resources and a central control device for the lamp resources, at least some lamp operating means are controlled and controlled by a data converter receiving and evaluating the control signals generated by the central control device and depending on the result Converts evaluation into commands for controlling the lamp resources controlled by the data converter. As already mentioned above, this makes it possible to increase the number of lamp operating means in the lighting system whose function can be controlled by means of the central control device.

Für den erfindungsgemäßen Datenkonverter sind mindestens zwei unterschiedliche Betriebsmodi vorgesehen, um ihn universell einsetzen zu können. Gemäß einem ersten bevorzugten Betriebsmodus werden die von der zentralen Steuervorrichtung empfangenen Steuersignale von der Auswertungseinheit des Datenkonverters in gleichartige Kommandos für alle von dem Datenkonverter kontrollierten Lampenbetriebsmittel umgewandelt. In diesem Betriebsmodus werden alle von dem Datenkonverter kontrollierten Lampenbetriebsmittel in derselben Weise gesteuert, das heißt, dass die dazugehörenden Lampen simultan ein- und ausgeschaltet sowie gedimmt werden können. Dadurch sind die vorgenannten Lampenbetriebsmittel und ihre Lampen automatisch zu einer Gruppe zusammengefasst. Ein besonderer Vorteil dieses Betriebsmodus besteht darin, dass anstelle einer gemäß des standardisierten DA-LI-Protokolls kommunizierenden zentralen Steuervorrichtung auch ein Taster als zentrale Steuervorrichtung verwendet werden kann, um den Datenkonverter und die von ihm kontrollierten Lampenbetriebsmittel zu steuern, da der erfindungsgemäße Datenkonverter vorzugweise sowohl digitale als auch analoge Steuersignale empfangen und auswerten kann.For the data converter according to the invention at least two different operating modes are provided in order to use it universally. According to a first preferred operating mode, the control signals received by the central control device are converted by the evaluation unit of the data converter into similar commands for all the lamp operating means controlled by the data converter. In this mode of operation, all of the lamp resources controlled by the data converter are controlled in the same manner, that is, the associated lamps can be simultaneously turned on and off and dimmed. As a result, the aforementioned lamp resources and their lamps are automatically grouped together. A particular advantage of this operating mode is that, instead of a central control device communicating according to the standardized DA-LI protocol, a pushbutton can also be used as the central control device to control the data converter and the lamp operating means controlled by it, since the data converter according to the invention preferably both digital and analog control signals can receive and evaluate.

Gemäß einem zweiten bevorzugten Betriebsmodus des Datenkonverters werden die von der zentralen Steuervorrichtung ausgesandten Steuersignale über den Datenkonverter, entsprechend einer Gruppenzugehörigkeit der von dem Datenkonverter kontrollierten Lampenbetriebsmittel von diesen Lampenbetriebsmitteln empfangen und ausgewertet. Der zweite Betriebsmodus ermöglicht die Ausweitung der Gruppeneinteilung der Lampenbetriebsmittel auf eine größere Anzahl von Lampenbetriebsmitteln als nur allein mit Hilfe der zentralen Steuervorrichtung betrieben werden könnten.According to a second preferred operating mode of the data converter, the control signals emitted by the central control device are received and evaluated by the data converter in accordance with a group affiliation of the lamp operating means controlled by the data converter from these lamp operating means. The second mode of operation allows the grouping of the lamp resources to be extended to a greater number of lamp resources than could be operated solely by the central controller.

Um auf einfache Weise, ohne Vergrößerung des Adressenvorrats der zentralen Steuervorrichtung, die oben genannte Ausweitung der Gruppeneinteilung auf die von dem Datenkonverter kontrollierten Lampenbetriebsmittel zu ermöglichen, wird während der Inbetriebnahmephase der Beleuchtungsanlage zunächst ein Inbetriebnahmeverfahren des Datenkonverters gestartet, um die von dem Datenkonverter kontrolliertten Lampenbebsebsimittel mit Adresscodes zu versehen, und anschließend wird ein Inbetriebnahmeverfahren der zentralen Steuervorrichtung gestartet, um den Datenkonverter und etwaige, unmittelbar von der zentralen Steuervorrichtung kontrollierte Lampenbetriebsmittel mit Adresscodes zu versehen, wobei zur Gruppeneinteilung der von dem Datenkonverter kontrollierten Lampenbetriebsmittel, der Datenkonverter von der zentralen Steuervorrichtung so oft selektiert wird bis alle von dem Datenkonverter kontrollierten Lampenbetriebsmittel in Gruppen eingeteilt sind, und wobei bei jeder Selektion des Datenkonverters sukzessiv ein von dem Datenkonverter kontrolliertes Lampenbetriebsmittel einer Lampenbetriebsmittelgruppe zugeordnet wird. Auf diese Weise kann trotz des beschränkten Adressenvorrats der zentralen Steuervorrichtung die Gruppeneinteilung der Lampenbetriebsmittel auf die von dem Datenkonverter kontrollierten Lampenbetriebsmittel erweitert werden. Insbesondere können dadurch Lampenbetriebsmittel, die unmittelbar von der zentralen Steuervorrichtung kontrolliert werden, mit Lampenbetriebsmitteln, die von dem Datenkonverter kontrolliert werden, in einer gemeinsam anzusteuernden Lampenbetriebsmittelgruppe zusammengefasst werden.In order to easily allow, without increasing the address supply of the central control device, the above-mentioned expansion of the group division to the controlled by the data converter lamp resources, a commissioning process of the data converter is first started during the commissioning phase of the lighting system to the monitored by the data converter Lampenbebsebsittel with To provide address codes, and then a commissioning process of the central control device is started to provide the data converter and any, directly controlled by the central control device lamp resources with address codes, wherein for grouping the data controlled by the data converter lamp resources, the data converter from the central control device is selected as many times until all of the data converter controlled lamp resources are divided into groups, and wherein for each selection of the data converter successively controlled by the data converter lamp resources is assigned to a lamp resource group. In this way, despite the limited address supply of the central control device, the grouping of the lamp resources can be extended to the lamp resources controlled by the data converter. In particular, lamp resources controlled directly by the central control device can thereby be combined with lamp operating means controlled by the data converter in a lamp resource group to be jointly controlled.

Die Auswertungseinheit des erfindungsgemäßen Datenkonverters umfasst vorzugsweise einen Mikrocontroller, um eine programmgesteuerte Auswertung der von einer zentralen Steuervorrichtung empfangenen Steuersignale sowie eine Überwachung der an den Datenausgang des Datenkonverters angeschlossenen Lampenbetriebsmittel zu ermöglichen. Der Datenkonverter führt in vorteilhafter Weise eine selbständige Status-Überwachung der an seinen Datenausgang angeschlossenen Lampenbetriebsmittel durch. Dadurch ist gewährleistet, dass auch bei den vom Datenkonverter kontrollierten Lampenbetriebsmitteln Fehlfunktionen detektiert werden können, obwohl der Datenkonverter von der zentralen Steuervorrichtung nur dieselben Steuersignale wie jedes unmittelbar an die zentrale Steuervorrichtung angeschlossene Lampenbetriebsmittel erhält. Abfragen der zentralen Steuervorrichtung nach dem Status der Lampenbetriebsmittel werden für die an den Datenausgang des Datenkonverters angeschlossenen Lampenbetriebsmittel vorteilhaft von dem Datenkonverter beantwortet, um sicherzustellen, dass die Rückmeldung an die zentrale Steuervorrichtung innerhalb des dafür vorgesehenen zulässigen Zeitfensters erfolgt. Vorzugsweise führt der Datenkonverter die vorgenannte Status-Überwachung zyklisch, in regelmäßigen zeitlichen Abständen durch, um die entsprechenden Werte bei Abfragen der zentralen Steuervorrichtung nach dem Status der Lampenbetriebsmittel für die Rückmeldung parat zu haben.The evaluation unit of the data converter according to the invention preferably comprises a microcontroller in order to enable a program-controlled evaluation of the control signals received from a central control device and monitoring of the lamp operating means connected to the data output of the data converter. The data converter advantageously performs independent status monitoring of the lamp operating means connected to its data output. This ensures that malfunctions can also be detected in the case of the lamp operating means controlled by the data converter, even though the data converter only receives the same control signals from the central control device as each lamp operating means directly connected to the central control device. Queries of the central control device for the status of the lamp operating means are advantageously answered by the data converter for the lamp operating means connected to the data output of the data converter in order to ensure that the feedback to the central control device takes place within the permissible time window provided for this purpose. Preferably, the data converter performs the aforementioned status monitoring cyclically, in regular time intervals to have the corresponding values in queries of the central control device for the status of the lamp resources for the feedback ready.

Der erfindungsgemäße Datenkonverter ist vorzugsweise in der Lage, den Typ der an seinen Datenausgang angeschlossenen Lampenbetriebsmittel zu erkennen. Dadurch kann der Datenkonverter Abfragen einer zentralen Steuervorrichtung nach den Eigenschaften der Lampenbetriebsmittel auswerten und für die von ihm kontrollierten Lampenbetriebsmittel beantworten. Vorzugsweise werden Abfragen einer zentralen Steuervorrichtung nach den Eigenschaften der Lampenbetriebsmittel für die an den Datenausgang des Datenkonverters angeschlossenen Lampenbetriebsmittel von dem Datenkonverter mit einem vorgegebenen Standardwert für die jeweilige abgefragte Eigenschaft der Lampenbetriebsmittel beantwortet, wenn sich die von dem Datenkonverter kontrollierten Lampenbetriebsmittel hinsichtlich der jeweiligen abgefragten Eigenschaft unterscheiden. Der Standardwert ist in vorteilhafter Weise so gewählt, dass er mit allen Typen von Lampenbetriebsmitteln verträglich ist. Dadurch ist gewährleistet, dass die zentrale Steuervorrichtung nicht mit einer Fehlermeldung aufgrund einer ausbleibenden Rückmeldung auf ihre Abfrage reagiert. Wenn aber die von dem Datenkonverter kontrollierten Lampenbetriebsmittel bezüglich der jeweiligen abgefragten Eigenschaft identisch sind, werden die vorgenannten Abfragen der zentralen Steuervorrichtung für die an dem Datenausgang des Datenkonverters angeschlossenen Lampenbetriebsmittel von dem Datenkonverter vorzugsweise mit einem Referenzwert für die jeweilige abgefragte Eigenschaft beantwortet, wobei der Datenkonverter als Referenzwert den Wert der jeweiligen abgefragten Eigenschaft eines von dem Datenkonverter ausgewählten Lampenbetriebsmittels der an seinen Datenausgang angeschlossenen Lampenbetriebsmittels verwendet. Mit anderen Worten, der Datenkonverter wählt eines der von ihm kontrollierten Lampenbetriebsmittel als Referenzgerät für eine oder mehrere Eigenschaften, beispielsweise für den maximaler Dimmbereich, aus und meldet dessen Wert für diese Eigenschaft bzw. Eigenschaften an die zentrale Steuervorrichtung zurück. In diesem Fall können die vorgenannten Abfragen der zentralen Steuervorrichtung von dem Datenkonverter für die von-ihm kontrollierten Lampenbetriebsmittel korrekt beantwortet werden.The data converter according to the invention is preferably able to detect the type of lamp operating means connected to its data output. As a result, the data converter can evaluate queries of a central control device according to the properties of the lamp operating means and answer them for the lamp operating means controlled by it. Preferably, queries of a central control device according to the characteristics of the lamp resources for the lamp resources connected to the data output of the data converter are answered by the data converter with a predetermined default value for the respective queried property of the lamp resources if the lamp resources controlled by the data converter differ with respect to the respective retrieved property , The default value is advantageously chosen to be compatible with all types of lamp resources. This ensures that the central control device does not respond with an error message due to a lack of feedback on their query. If, however, the lamp resources controlled by the data converter are identical with respect to the respective retrieved property, the abovementioned queries of the central control device for the lamp operating means connected to the data output of the data converter are preferably answered by the data converter with a reference value for the respective queried property, the data converter acting as Reference value uses the value of the respective retrieved property of a lamp operating means selected by the data converter of the lamp operating means connected to its data output. In other words, the data converter selects one of the lamp resources that it controls as the reference device for one or more properties, for example for the maximum dimming range, and returns its value for this property or characteristics to the central control device. In this case, the aforementioned queries of the central control device can be correctly answered by the data converter for the lamp resources controlled by it.

The data converter 10 has a voltage supply unit 11 which can be connected to the mains voltage and supplies the data converter with electrical energy. In addition, the data converter 10 has a data input 12, which is connectable to an output of a central control device of a lighting system, and a data output 13, which is connectable to a plurality of lamp operating means.

The evaluation unit 14 is designed as a programmable microcontroller. The voltage supply unit 11 provides via the data output 13 the interface current for the communication with the lamp operating means connected to the data output 13. Both the communication of the data converter 10 with the central control device via the data input 12 and its communication with the lamp operating means connected to the data output 13 are bidirectional.

Figur 2 zeigt eine schematische Darstellung einer Beleuchtungsanlage mit einer zentralen Steuervorrichtung 2, einem Datenkonverter 1, ersten Lampenbetriebsmitteln 3.1 bis 3.63 und zweiten Lampenbetriebsmitteln 4.1 bis 4.64. Der Steuerausgang 21 der zentralen Steuervorrichtung 2 ist über Leitungen mit den ersten Lampenbetriebsmitteln 3.1 bis 3.63 und mit dem Datenkonverter 1 verbunden. Die ersten Lampenbetriebsmittel 3.1 bis 3.63 und der Datenkonverter 1 sind parallel geschaltet. Die zweiten Lampenbetriebsmittel 4.1 bis 4.64 sind an den Datenausgang 13 des Datenkonverters 1 angeschlossen. Sie sind ebenfalls parallel geschaltet. Die ersten Lampenbetriebsmittel 3.1 bis 3.63 werden unmittelbar von der zentralen Steuervorrichtung kontrolliert, während die zweiten Lampenbetriebsmittel 4.1 bis 4.64 von dem Datenkonverter 1 kontrolliert werden, und zwar in Abhängigkeit von den Steuersignalen, die der Datenkonverter 1 an seinem Dateneingang 12 von der zentralen Steuervorrichtung 1 empfängt. Bei den Lampenbetriebsmitteln 3.1 bis 3.63 und 4.1 bis 4.64 handelt es sich um Vorschaltgeräte für Entladungslampen, Transformatoren für Niedervolt-Halogenglühlampen und Treiberschaltungen für Leuchtdioden. Dementsprechend werden unter dem Begriff Lampe die Leuchtmittel Entladungslampe, Glühlampe und Leuchtdiode subsummiert. Die zentrale Steuervorrichtung 2 kommuniziert Steuersignale gemäß des standardisierten DALI-Protokolls über ihren Steuerausgang 21 mit den daran angeschlossenen dreiundsechzig Lampenbetriebsmitteln 3.1 bis 3.63 und dem Datenkonverter 1. Jedes der dreiundsechzig Lampenbetriebsmittel 3.1 bis 3.63 und der Datenkonverter 1 besitzt einen Adressencode aus dem vierundsechzig individuelle Adressen umfassenden Adressenvorrat der zentralen Steuervorrichtung 2. Außerdem können diesen Lampenbetriebsmitteln 3.1 bis 3.63 und dem Datenkonverter 1 Gruppenadressencodes aus dem sechzehn Gruppenadressen umfassenden Gruppenadressenvorrat der zentralen Steuervorrichtung 2 zugewiesen sein, um die einzelnen Lampenbetriebsmittel 3.1 bis 3.63 und gegebenenfalls den Datenkonverter 1 zu gemeinsam anzusteuernden Gruppen zusammenzufassen. Die gruppenweise zusammengefassten Lampenbetriebsmittel bzw. deren Leuchtmittel werden simultan ein-, ausgeschaltet und gedimmt. FIG. 2 shows a schematic representation of a lighting system with a central control device 2, a data converter 1, the first lamp operating means 3.1 to 3.63 and second lamp resources 4.1 to 4.64. The control output 21 of the central control device 2 is connected via lines to the first lamp operating means 3.1 to 3.63 and to the data converter 1. The first lamp operating means 3.1 to 3.63 and the data converter 1 are connected in parallel. The second lamp operating means 4.1 to 4.64 are connected to the data output 13 of the data converter 1. They are also connected in parallel. The first lamp operating means 3.1 to 3.63 are directly controlled by the central control device, while the second lamp operating means 4.1 to 4.64 are controlled by the data converter 1, in response to the control signals which the data converter 1 receives at its data input 12 from the central control device 1 , The lamps 3.1 to 3.63 and 4.1 to 4.64 are ballasts for discharge lamps, transformers for low-voltage halogen incandescent lamps and driver circuits for light-emitting diodes. Accordingly, the lamp bulbs the discharge lamp, light bulb and LED are subsumed. The central control device 2 communicates control signals according to the standardized DALI protocol via its control output 21 with the sixty-three lamp operating means 3.1 to 3.63 connected thereto and the data converter 1. Each of the sixty-three lamp operating means 3.1 to 3.63 and the data converter 1 has an address code comprising sixty-four individual addresses Address supply of the central control device 2. In addition, these lamp resources 3.1 to 3.63 and the data converter 1 group address codes from the sixteen group addresses comprehensive group address resource of the central control device 2 assigned to the individual lamp resources 3.1 to 3.63 and possibly the data converter 1 to jointly controlled groups summarize. The groups summarized lamp resources or their bulbs are simultaneously switched on, off and dimmed.

Nachstehend werden zwei unterschiedliche Betriebsverfahren der in Figur 2 schematisch abgebildeten Beleuchtungsanlage beschrieben, die zwei unterschiedlichen Betriebsmodi des Datenkonverters 1 entsprechen.Below are two different operating procedures of in FIG. 2 schematically illustrated lighting system, which correspond to two different operating modes of the data converter 1.

Gemäß des ersten Betriebsmodus des Datenkonverters 1 kommuniziert die zentrale Steuervorrichtung 2 mit dem Datenkonverter 1 auf die gleiche Weise wie mit den ersten Lampenbetriebsmitteln 3.1 bis 3.63. Digitale Steuersignale, die der Datenkonverter 1 an seinem Dateneingang 13 von der zentralen Steuervorrichtung 2 empfängt, werden von der Auswertungseinheit 14 des Datenkonverters 1 ausgewertet und in digitale Kommandos umgewandelt, die über den Datenausgang 13 an alle daran angeschlossenen vierundsechzig zweiten Lampenbetriebsmittel 4.1 bis 4.64 kommuniziert werden. Das heißt, alle zweiten Lampenbetriebsmittel 4.1 bis 4.64 erhalten dieselben Kommandos und deren Leuchtmittel können daher nur simultan ein-, ausgeschaltet und gedimmt werden. Die zweiten Lampenbetriebsmittel 4.1 bis 4.64 sind nicht einzeln, sondern nur als Gruppe ansprechbar und steuerbar. Dementsprechend kann der Datenkonverter 1 eine Statusabfrage der zentralen Steuervorrichtung 2 für die Lampenbetriebsmittel 4.1 bis 4.64 nur gruppenübergreifend beantworten. Im Falle einer defekten Lampe oder eines defekten zweiten Lampenbetriebsmittels 4.1 bis 4.64 wird der Datenkonverter 1 nur das Vorliegen eines Defektes an die zentrale Steuervorrichtung 2 melden, ohne aber die Anzahl der defekten Lampen bzw. Lampenbetriebsmittel 4.1 bis 4.64 feststellen zu können sowie die defekten Lampen bzw. Lampenbetriebsmittel 4.1 bis 4.64 lokalisieren zu können. Individuell ansprechbar und steuerbar sind nur die unmittelbar an die zentrale Steuervorrichtung 2 angeschlossenen ersten Lampenbetriebsmittel 3.1 bis 3.63.According to the first operating mode of the data converter 1, the central control device 2 communicates with the data converter 1 in the same way as with the first lamp operating means 3.1 to 3.63. Digital control signals which the data converter 1 receives at its data input 13 from the central control device 2 are evaluated by the evaluation unit 14 of the data converter 1 and converted into digital commands, which are communicated via the data output 13 to all sixty-four second lamp operating means 4.1 to 4.64 connected thereto , This means that all second lamp operating means 4.1 to 4.64 receive the same commands and their lighting means can therefore only be switched on, off and dimmed simultaneously. The second lamp resources 4.1 to 4.64 are not individually, but only responsive and controllable as a group. Accordingly, the data converter 1 can answer a status query of the central control device 2 for the lamp resources 4.1 to 4.64 only across groups. In the case of a defective lamp or a defective second lamp operating means 4.1 to 4.64, the data converter 1 will report only the presence of a defect to the central control device 2, but without being able to determine the number of defective lamps or lamp resources 4.1 to 4.64 and the defective lamps or To locate lamp resources 4.1 to 4.64. Individually addressable and controllable are only the first lamp operating means 3.1 to 3.63 connected directly to the central control device 2.

Der Vorteil des ersten Betriebsmodus ist, dass keine spezielle Inbetriebnahme des Datenkonverters und seiner nachgeschalteten Lampenbetriebsmittel 4.1 bis 4.64 erforderlich ist und der Datenkonverter 1 kompatibel zu allen zentralen Steuervorrichtungen mit DALI-Schnittstelle 21 ist. Nachteilig ist, dass dieser Betriebsmodus keine Gruppeneinteilung der Lampenbetriebsgeräte 4.1 bis 4.64 erlaubt.The advantage of the first mode of operation is that no special commissioning of the data converter and its downstream lamp resources 4.1 to 4.64 is required and the data converter 1 is compatible with all central control devices with DALI interface 21. The disadvantage is that this operating mode does not allow grouping of the lamp operating devices 4.1 to 4.64.

Auch gemäß des zweiten Betriebsmodus des Datenkonverters 1 kommuniziert die zentrale Steuervorrichtung 2 mit dem Datenkonverter 1 auf die gleiche Weise wie mit den ersten Lampenbetriebsmitteln 3.1 bis 3.63. Digitale Steuersignale, die der Datenkonverter 1 an seinem Dateneingang 13 von der zentralen Steuervorrichtung 2 empfängt, werden von der Auswertungseinheit 14 des Datenkonverters 1 ausgewertet und in digitale Kommandos umgewandelt, die über den Datenausgang 13 aber in der Regel nicht an alle daran angeschlossenen vierundsechzig zweiten Lampenbetriebsmittel 4.1 bis 4.64, sondern selektiv nur an einige vorbestimmte der vierundsechzig zweiten Lampenbetriebsmittel 4.1 bis 4.64 kommuniziert werden. Das heißt, die zweiten Lampenbetriebsmittel 4.1 bis 4.64 werden, im Gegensatz zu dem oben beschriebenen ersten Betriebsmodus, entsprechend ihrer Gruppenzugehörigkeit von der zentralen Steuervorrichtung 2 und dem Datenkonverter 1 gesteuert.Also according to the second operating mode of the data converter 1, the central control device 2 communicates with the data converter 1 in the same manner as with the first lamp operating means 3.1 to 3.63. Digital control signals which the data converter 1 receives at its data input 13 from the central control device 2 are evaluated by the evaluation unit 14 of the data converter 1 and converted into digital commands, which are communicated via the data output 13 but not generally to all sixty-four second lamp resources 4.1 to 4.64 connected thereto, but selectively to only a few predetermined ones of the sixty-four second lamp resources 4.1 to 4.64. That is, the second lamp operating means 4.1 to 4.64 are controlled by the central control device 2 and the data converter 1 according to their group membership, unlike the above-described first operation mode.

Voraussetzung für die Einteilung der zweiten Lampenbetriebsmittel 4.1 bis 4.64 in Gruppen ist, dass zunächst während einer Inbetriebnahmephase die zweiten Lampenbetriebsmittel 4.1 bis 4.64 mit einem Adressencode versehen werden, um sie für den Datenkonverter 1 und die Steuervorrichtung 2 unterscheidbar zu machen. Idealerweise wird die Inbetriebnahme ohne externen Eingriff vom Datenkonverter 1 automatisch gestartet und durchgeführt, sobald der Datenkonverter 1 Lampenbetriebsmittel ohne Adresse erkennt, die an seinen Datenausgang 13 angeschlossen sind. Alternativ kann diese Inbetriebnahme aber auch über einen am Datenkonverter 1 befindlichen Taster oder über ein spezielles Kommando der zentralen Steuervorrichtung gestartet werden. Der Datenkonverter 1 weist während seiner Inbetriebnahme jedem der Lampenbetriebsmittel 4.1 bis 4.64 einen individuellen Adressencode aus seinem Adressenvorrat zu, den jedes Lampenbetriebsmittel 4.1 bis 4.64 dauerhaft speichert. Durch diesen Adressencode sind die zweiten Lampenbetriebsmittel 4.1 bis 4.64 für den Datenkonverter 1 unterscheidbar. Anschließend wird die Inbetriebnahme der zentralen Steuervorrichtung 2 und der an ihren Steuerausgang 21 angeschlossenen Lampenbetriebsmittel 3.1 bis 3.63 sowie des Datenkonverters 1 gestartet. Die Lampenbetriebsmittel 3.1 bis 3.63 sowie der Datenkonverter 1 werden in maximal sechzehn Gruppen eingeteilt, entsprechend dem verfügbaren Gruppenadressenvorrat der zentralen Steuervorrichtung 2, indem jedem Lampenbetriebsmittel 3.1 bis 3.63 und dem Datenkonverter 1 von der zentralen Steuervorrichtung 2 jeweils mindestens eine der sechzehn Gruppenadressen zugewiesen wird. Die Übernahme des jeweiligen Gruppenadressencodes durch die Lampenbetriebsmittel 3.1 bis 3.63 und 4.1 bis 4.64 kann beispielsweise durch sukzessives Bestücken der Lampenbetriebsmittel 3.1 bis 3.63 und 4.1 bis 4.64 entsprechend ihrer Gruppenzugehörigkeit erreicht werden, wie beispielsweise in der Offenlegungsschrift EP 0 639 938 A1 beschrieben ist. Eine andere, bevorzugte Möglichkeit der Gruppenzuordnung besteht darin, die Gruppenadressen den einzelnen Lampenbetriebsmitteln 3.1. bis 3.63 und dem Datenkonverter 1 über die Bedienungselemente der zentralen Steuervorrichtung 2 zuzuweisen. Dabei wird jedes Lampenbetriebsmittel 3.1 bis 3.63 genau einmal von der zentralen Steuervorrichtung 2 ausgewählt und ihm mit Hilfe der Bedienungselemente mindestens eine Gruppenadresse zugewiesen. Der Datenkonverter 1 wird während der Gruppenzuordnung vierundsechzig mal von der zentralen Steuervorrichtung 2 ausgewählt oder aufgerufen, entsprechend der Anzahl der an seinem Datenausgang 13 angeschlossenen Lampenbetriebsmittel 4.1 bis 4.64. Bei jedem Aufruf des Datenkonverters 1 durch die zentrale Steuervorrichtung 2 wird sukzessiv einem der an dem Datenausgang 13 des Datenkonverters 1 angeschlossenen Lampenbetriebsmittel 4.1 bis 4.64 mindestens eine Gruppenadresse zugewiesen. Das heißt, bei dem ersten Aufruf des Datenkonverters 1 wird dem Lampenbetriebsmittel 4.1 mindestens eine Gruppenadresse zugewiesen und bei dem zweiten Aufruf des Datenkonverters 1 wird dem Lampenbetriebsmittel 4.2 mindestens eine Gruppenadresse zugewiesen und so weiter bis alle viersechzig Lampenbetriebsmittel 4.1 bis 4.64 mit Gruppenadressen versehen sind. Der Datenkonverter 1 reicht dabei die von der zentralen Steuervorrichtung 2 an ihn vergebenen Gruppenadressen gemäß der obigen Vorschrift an die zweiten Lampenbetriebsmittel 4.1 bis 4.64 weiter. Die einzelnen Lampenbetriebsmittel 3.1 bis 3.63 und 4.1 bis 4.64 speichern die ihnen zugewiesenen Gruppenadressen in einem nichtflüchtigen Speichermittel, beispielsweise in einem EEPROM. Auf diese Weise können auch die an den Datenausgang 13 des Datenkonverters 1 angeschlossenen Lampenbetriebsmittel 4.1 bis 4.64 in Gruppen eingeteilt werden. Es ist sogar möglich, erste Lampenbetriebsmittel 3.1 bis 3.63 und zweite Lampenbetriebsmittel 4.1 bis 4.64 in derselben Gruppe zusammenzufassen.
Besteht beispielsweise die erste Lampenbetriebsmittelgruppe aus den Lampenbetriebsmitteln 3.1, 4.1 und 4.2, so wird ein für diese Lampenbetriebsmittelgruppe bestimmter Steuerbefehl, von der zentralen Steuervorrichtung 2 über den Steuerausgang 21 an alle erste Lampenbetriebsmittel 3.1 bis 3.63 und über den Datenkonverter 1 an alle zweite Lampenbetriebsmittel 4.1 bis 4.64 gesandt. Allerdings werden nur die Lampenbetriebsmittel 3.1, 4.1 und 4.2 diesen Steuerbefehl ausführen, da nur die von diesen Lampenbetriebsmitteln 3.1, 4.1 und 4.2 gespeicherte Gruppenadresse mit der im Steuerbefehl angegebenen Gruppenadresse übereinstimmt. Der Datenkonverter 1 arbeitet in diesem Fall wie ein Slave, das heißt, er gibt den Steuerbefehl an die an seinem Datenausgang 13 angeschlossenen Lampenbetriebsmittel 4.1 bis 4.64 weiter.A prerequisite for the division of the second lamp resources 4.1 to 4.64 in groups is that initially during a startup phase, the second lamp resources 4.1 to 4.64 are provided with an address code to make them distinguishable for the data converter 1 and the control device 2. Ideally, the commissioning without external intervention by the data converter 1 is automatically started and carried out as soon as the data converter 1 detects lamp resources without an address, which are connected to its data output 13. Alternatively, this startup can also be started via a button located on the data converter 1 or via a special command of the central control device. During its commissioning, the data converter 1 assigns to each of the lamp operating means 4.1 to 4.64 an individual address code from its address supply which each lamp operating means 4.1 to 4.64 permanently stores. By means of this address code, the second lamp operating means 4.1 to 4.64 can be distinguished for the data converter 1. Subsequently, the commissioning of the central control device 2 and connected to its control output 21 lamp resources 3.1 to 3.63 and the data converter 1 is started. The lamp resources 3.1 to 3.63 and the data converter 1 are divided into a maximum of sixteen groups, according to the available group address supply of the central control device 2, by each lamp resources 3.1 to 3.63 and the data converter 1 is assigned by the central control device 2 each at least one of the sixteen group addresses. The adoption of the respective group address codes by the lamp resources 3.1 to 3.63 and 4.1 to 4.64 can be achieved, for example, by successively populating the lamp resources 3.1 to 3.63 and 4.1 to 4.64 according to their group membership, such as for example in the published patent application EP 0 639 938 A1 is described. Another, preferred way of group assignment is the group addresses the individual lamp resources 3.1. to 3.63 and assign the data converter 1 via the controls of the central control device 2. In this case, each lamp operating means 3.1 to 3.63 selected exactly once by the central control device 2 and assigned to him by means of the controls at least one group address. The data converter 1 is selected or called up sixty-four times by the central control device 2 during the group assignment, corresponding to the number of the lamp operating means 4.1 to 4.64 connected to its data output 13. Each time the data converter 1 is called by the central control device 2, at least one group address is successively assigned to one of the lamp operating means 4.1 to 4.64 connected to the data output 13 of the data converter 1. That is, at the first call of the data converter 1, at least one group address is assigned to the lamp resource 4.1 and at the second call of the data converter 1 the lamp resource 4.2 is assigned at least one group address and so on until all four sixty lamp resources 4.1 to 4.64 are provided with group addresses. The data converter 1 extends the group addresses assigned to it by the central control device 2 in accordance with the above rule to the second lamp operating means 4.1 to 4.64. The individual lamp resources 3.1 to 3.63 and 4.1 to 4.64 store the group addresses allocated to them in a non-volatile memory means, for example in an EEPROM. In this way, the lamp operating means 4.1 to 4.64 connected to the data output 13 of the data converter 1 can also be divided into groups. It is even possible to combine first lamp resources 3.1 to 3.63 and second lamp resources 4.1 to 4.64 in the same group.
If, for example, the first lamp operating group consists of the lamp operating means 3.1, 4.1 and 4.2, a control command determined for this lamp operating group will be sent from the central control device 2 via the control output 21 to all first lamp operating means 3.1 to 3.63 and via the data converter 1 to all second lamp operating means 4.1 to 4.64 sent. However, only the lamp operating means 3.1, 4.1 and 4.2 execute this control command, since only the group address stored by these lamp operating means 3.1, 4.1 and 4.2 coincides with the group address indicated in the control command. The data converter 1 operates in this case as a slave, that is, it passes the control command to the connected to its data output 13 lamp operating 4.1 to 4.64 on.

Bezüglich der an seinen Datenausgang 13 angeschlossenen Lampenbetriebsmittel 4.1 bis 4.64 arbeitet der Datenkonverter 1 hingegen wie ein Master, das heißt beispielsweise, Rückmeldungen der zweiten Lampenbetriebsmittel 4.1 bis 4.64 zu ihrem aktuellen Status auf entsprechende Anfragen der zentralen Steuervorrichtung 2 werden von dem Datenkonverter 1 und nicht von der zentralen Steuervorrichtung 2 ausgewertet. Die zentrale Steuervorrichtung 2 wertet entsprechende Rückmeldungen der ersten Lampenbetriebsmittel 3.1 bis 3.63 aus. Der Datenkonverter 1 führt selbständig durch zyklisches Abfragen der ihm nachgeschalteten Lampenbetriebsmittel 4.1 bis 4.64 eine Statusüberwachung dieser Lampenbetriebsmittel durch. Anhand dieses Statusabbildes kann der Datenkonverter 1 Abfragen der zentralen Steuervorrichtung 2 unmittelbar, ohne Zeitverzögerung beantworten. Ein Durchreichen von Abfragen der zentralen Steuervorrichtung 2 an die dem Datenkonverter 1 nachgeschalteten Lampenbetriebsmittel ist nicht möglich, weil der zeitliche Abstand zwischen einer Abfrage von der zentralen Steuervorrichtung 2 und der Erzeugung einer entsprechenden Rückmeldung der Lampenbetriebsmittel 4.1 bis 4.64 so groß ist, dass der gemäß des DALI-Standards zulässige maximale zeitliche Abstand zwischen der Abfrage und dem Eintreffen der Rückmeldung nicht eingehalten werden kann.With respect to the connected to its data output 13 lamp resources 4.1 to 4.64, the data converter 1, however, works like a master, that is, for example, feedback the second lamp resources 4.1 to 4.64 to their current status to corresponding requests of the central control device 2 are from the data converter 1 and not from the central control device 2 evaluated. The central control device 2 evaluates corresponding feedback from the first lamp operating means 3.1 to 3.63. The data converter 1 independently carries out a status monitoring of these lamp operating means by cyclically querying the downstream lamp operating means 4.1 to 4.64. On the basis of this status image, the data converter 1 can answer queries of the central control device 2 immediately, without a time delay. It is not possible to pass through queries of the central control device 2 to the lamp operating means connected downstream of the data converter 1, because the time interval between a query from the central control device 2 and the generation of a corresponding feedback of the lamp operating means 4.1 to 4.64 is so great that the voltage according to FIG DALI standards allowable maximum time interval between the query and the arrival of feedback can not be met.

Der Datenkonverter 1 ist auf den ersten Betriebsmodus voreingestellt. Um ihn in den zweiten Betriebsmodus zu versetzen, muss er durch Betätigen eines am Gehäuse des Datenkonverters 1 angeordneten Schalters oder mittels eines speziellen Kommandos der zentralen Steuervorrichtung 2 in diesen umgeschaltet werden. Das Betätigen dieses Schalters oder das vorgenannten Kommando initiiert das oben erläuterte Inbetriebnahmeverfahren.The data converter 1 is preset to the first operating mode. In order to place it in the second operating mode, it must be switched over by actuating a switch arranged on the housing of the data converter 1 or by means of a special command of the central control device 2. The actuation of this switch or the aforementioned command initiates the startup procedure explained above.

Der Datenkonverter 1 ist derart konfiguriert, dass er an seinem Dateneingang 12 sowohl digitale als auch analoge Steuersignale empfangen und auswerten kann. Anstelle der in Figur 2 schematisch dargestellten, gemäß des standardisierten DALI-Protokolls arbeitenden zentralen Steuervorrichtung 2, die den Dateneingang 12 des Datenkonverters 1 mit digitalen Steuerbefehlen beaufschlagt, kann auch eine mit analogen Steuerbefehlen arbeitende zentrale Steuervorrichtung, beispielsweise ein Taster 5 gemäß der schematischen Darstellung in Figur 3 verwendet werden.The data converter 1 is configured such that it can receive and evaluate both digital and analog control signals at its data input 12. Instead of in FIG. 2 schematically, according to the standardized DALI protocol working central control device 2, which acts on the data input 12 of the data converter 1 with digital control commands, can also operate with analog control commands central control device, such as a button 5 according to the schematic representation in FIG FIG. 3 be used.

Der Dateneingang 12 des Datenkonverters 1 ist über den Taster 5 mit der Netzwechselspannung N, L verbunden. An den Datenausgang 13 des Datenkonverters 1 sind insgesamt vierundsechzig parallel geschaltete Lampenbetriebsmittel 6.1 bis 6.64 angeschlossen. Durch Betätigen des Tasters 5 wird die Verbindung des Dateneingangs 12 zur Netzwechselspannung hergestellt bzw. unterbrochen. Die Auswertungseinheit 14 generiert in Abhängigkeit von der Betätigung des Tasters 5, der Dauer der Tasterbetätigung und dem momentanen Betriebszustand der Lampenbetriebsmittel 6.1 bis 6.64 Steuerbefehle für die an den Datenausgang 13 angeschlossenen Lampenbetriebsmittel 6.1 bis 6.64. Mittels des Tasters 5 werden alle Lampenbetriebsmittel 6.1 bis 6.64 simultan in gleicher Weise gesteuert. Das heißt, die von den Lampenbetriebsmitteln 6.1 bis 6.64 betriebenen Leuchtmittel werden simultan ein- ausgeschaltet und gedimmt. Die Einzelheiten der Steuerung der Lampenbetriebsmittel 6.1 bis 6.64 mittels eines Tasters 5 ist ausführlich in der WO 01/52607 A1 beschrieben und soll daher hier nicht weiter erläutert werden. Ebenso beschreibt die WO 01/52607 A1 auch auf welche Weise zwischen analogen und digitalen Steuersignalen unterscheiden wird. Der Datenkonverter 1 unterscheidet digitale und analoge Steuersignale an seinem Dateneingang 12 auf dieselbe Weise wie in der oben zitierten Offenlegungsschrift.The data input 12 of the data converter 1 is connected via the button 5 to the AC line voltage N, L. At the data output 13 of the data converter 1 a total of sixty-four parallel lamp operating means 6.1 to 6.64 are connected. By pressing the button 5, the connection of the data input 12 to the mains AC voltage is established or interrupted. The evaluation unit 14 generates in response to the operation of the button 5, the duration of the button operation and the current operating state of the lamp operating 6.1 to 6.64 control commands for the connected to the data output 13 lamp operating 6.1 to 6.64. By means of the button 5, all the lamp operating means 6.1 to 6.64 are simultaneously controlled in the same way. This means that the lamps operated by the lamp operating means 6.1 to 6.64 are switched on and dimmed simultaneously. The details of the control of the lamp resources 6.1 to 6.64 by means of a button 5 is described in detail in the WO 01/52607 A1 described and therefore will not be explained here. Likewise describes the WO 01/52607 A1 also in what way will distinguish between analog and digital control signals. The data converter 1 distinguishes digital and analog control signals at its data input 12 in the same way as in the above-cited published patent application.
