The control commands, for example, from the Central unit 31 can therefore predetermined input, output or Transmit dimming control values.

Wenn die Befehlre über den DC-Bus 37 übermittelt werden, weist die Zentraleinheit oder eine separate zentrale Steuerung einen Poweline-Modulator und die Betriebsmittel entsprechend einen Powerline-Demodulator auf. Fall die Kommunikation bidirektional über den Bus 37 erfolgen soll, weisen beide genannten Kommunikationspartner sowohl einen Powerline-Modulator wie auch einen Powerline-Demodulator auf.When the commands are transmitted via the DC bus 37, indicates the central unit or a separate central Control a poweline modulator and resources accordingly a powerline demodulator on. Case the Communication bidirectionally via the bus 37, Both communication partners have both a Powerline modulator as well as a powerline demodulator on.

Auch wenn in dem Ausführungsbeispiel von Fig. 3 dargestellt ist, dass an jedes der an der Zentraleinheit 31 angeschlossenen Betriebsmittel-Module 40, 41 bzw. 42 Leuchtmittel unterschiedlichen Typs angeschlossen sind, können natürlich auch Betriebsmittel-Module an die Zentraleinheit 31 angeschlossen werden, die zumindest teilweise Leuchtmittel gleicher Art versorgen. Vorstellbar ist z.B., dass an die Zentraleinheit 31 zur Erzeugung einer farbigen Lichtsteuerung je ein Betriebsmittel-Modul mit grünen Leuchtmitteln, roten Leuchtmitteln und blauen Leuchtmitteln angeschlossen ist. In diesem Fall sind die Leuchtmittel vorzugsweise LEDs.Although in the embodiment of Fig. 3rd is shown that to each of the central unit 31 connected resource modules 40, 41 and 42, respectively Bulbs of different types are connected, Of course, you can also attach resource modules to the Central unit 31 are connected, at least partially supply bulbs of the same kind. imaginable is, for example, that to the central unit 31 for generating a colored light control depending on a resource module with green bulbs, red bulbs and blue Light source is connected. In this case, the Light source preferably LEDs.

Über die oben angeführten Steuerbefehle beispielsweise von der Zentraleinheit 31 an die lokalen Steuereinheiten 35, 35' bzw. 35" können somit Lichtmischeffekte ggf. auch dynamischer Art durch entsprechende Übermittlung von Dimmbefehlen an die einzelnen Farben erzeugt werden.For example, from the commands above the central unit 31 to the local control units 35, 35 'or 35 "can thus possibly also light mixing effects dynamic nature by appropriate transmission of Dimming commands to the individual colors are generated.

Wie im obigen Abschnitt ausgeführt, sind also die in der Zentraleinheit 31 angeschlossenen Betriebsmittelmodule 40, 41 bzw. 42 elektrisch mit der Zentraleinheit 31 über den DC-Ausgangsbus 37 verbunden.As stated in the section above, so in the Central unit 31 connected resource modules 40, 41 and 42 electrically connected to the central unit 31 via the DC output bus 37 connected.

Wie schematisch durch das Bezugszeichen 39 dargestellt ist, können die Betriebsmittel-Module 40, 41, 42 auch mechanisch, beispielsweise im Sinne einer Steckverbindung entweder mit der Zentraleinheit 31 oder aber mit weiteren gleichartigen Betriebsmitteln-Modulen verbunden werden. Vorteilhaft ist dabei, dass gleichzeitig mit dem Aufstecken, d.h. dem Schaffen der mechanischen Verbindung zwischen einem Betriebsmittel-Modul und der Zentraleinheit 31 bzw. einem weiteren Betriebsmittel-Modul gleicher Art auch die elektrische Kontaktierung der angeführten Elemente über den DC-Ausgangsbus 37 erfolgt. Die elektrische Kontaktierung erfolgt dabei vorzugsweise ebenfalls über Steckkontakte, die auch wieder gelöst werden können. In diesem Fall weisen die Gehäuse der Betriebsmittel-Module auf einer Fläche männliche elektrische Steckerelemente und auf einer weiteren Fläche korrespondierende männliche Steckerelemente auf.As schematically represented by the reference numeral 39 can, the resource modules 40, 41, 42 also mechanically, for example in the sense of a plug connection either with the central unit 31 or with others similar resources modules are connected. It is advantageous that simultaneously with the Plug on, i. the creation of the mechanical connection between a resource module and the central unit 31 or another resource module of the same kind also the electrical contacting of the cited Elements via the DC output bus 37 takes place. The electrical contacting is preferably carried out also via plug contacts, which also solved again can be. In this case, the housings of the Equipment modules on a male surface electrical connector elements and on another surface corresponding male connector elements.

Die mechanische Verbindung kann auch über andere Mittel, wie bspw. Klammern etc. geschaffen werden.The mechanical connection can also be achieved by other means, such as brackets, etc. are created.

Die mechanischen Verbindungen 39 sind insbesondere als lösbare mechanische Verbindungen ausgeführt, um das Beleuchtungs-Ansteuersystem besonders flexibel auszugestalten.The mechanical connections 39 are in particular as releasable mechanical connections performed to the Lighting control system particularly flexible embody.
