Zentraler Punkt der Erfindung ist es dabei, dass die Einheit Gleichrichter/PFC nicht mehr lokal in jedem Betriebsgerät, sondern zentral für mehrere Betriebsgeräte vorgesehen ist. Die Verbindung zwischen dieser Zentrale und den einzelnen Betriebsgeräten erfolgt erfindungsgemäß über einen DC-Ausgangskreis.The central point of the invention is that the unit rectifier / PFC is no longer provided locally in each operating device, but centrally for several operating devices.

Gleichzeitig soll trotz der zentralen Ausgestaltung eine flexible und auf die Bedürfnisse der angeschlossenen Betriebsgeräte angepasste Versorgung ermöglicht werden.At the same time a flexible and adapted to the needs of the connected equipment supply is to be made possible despite the central design.
Gemäß einem ersten Aspekt der Erfindung ist ein System zur Ansteuerung von Betriebsgeräten für Leuchtmittel vorgesehen. Dieses System weist eine Zentraleinheit auf, die eine Gleichrichterschaltung aufweist und mit Wechselspannung versorgbar ist. Weiterhin sind mehrere Betriebsgeräte vorgesehen, denen jeweils wenigstens ein Leuchtmittel zugeordnet ist. Die Zentraleinheit versorgt die Betriebsgeräte mit Gleichspannung über mehrere Ausgangskreise. Dabei können wenigstens zwei Ausgangskreis unterschiedliche Gleichspannungspegel aufweisen. Somit wird eine flexible Spannungsversorgung über die DC-Ausgangskreise gewährleistet.According to a first aspect of the invention, a system for controlling operating devices for lighting means is provided. This system has a central unit which has a rectifier circuit and can be supplied with alternating voltage. Furthermore, a plurality of operating devices are provided, each of which is associated with at least one light source. The central unit supplies the operating devices with DC voltage via several output circuits. At least two output circuits may have different DC voltage levels. This ensures a flexible power supply via the DC output circuits.
Die Zentraleinheit kann weiterhin eine Leistungsfaktor-Korrekturschaltung (PFC-)Schaltung aufweisen.The central processing unit may further include a power factor correction (PFC) circuit.
Den Ausgangskreisen mit unterschiedlichen Gleichspannungspegeln können Betriebsgeräte für unterschiedliche Typen an Leuchtmitteln (beispielsweise Gasentladungslampe, LED, etc.) zugeordnet sein.The output circuits with different DC voltage levels can be control gear for different types of lighting (for example, gas discharge lamp, LED, etc.) to be assigned.
Die Zentraleinheit kann zusätzlich auch einen reinen Digitalsignal-Ausangskreis aufweisen, der also nicht zur Leistungsversorgung dient.In addition, the central unit can also have a pure digital signal output circuit, which therefore does not serve for the power supply.
Mit dem Digitalsignal-Ausgangskreis kann ein Betriebsgerät verbunden sein, das eine von der Zentraleinheit unabhängige Spannungsversorgung, insbesondere eine Netz-Wechselspannungsversorgung aufweist.With the digital signal output circuit, an operating device may be connected, which has a power supply independent of the central unit, in particular a mains AC power supply.
Einer der Ausgangskreise der Zentraleinheit kann mit Masse verbunden sein, wobei wenigstens zwei weitere Ausgangskreise Gleichspannungspegel aufweisen, die um das Massepotential herum symmetrisch ausgelegt sind.One of the output circuits of the central unit may be connected to ground, wherein at least two further output circuits have DC voltage levels which are designed symmetrically around the ground potential.
Alternativ können diese beiden weiteren Ausgangskreise auch asymmetrisch um das Massepotential herum ausgelegt sein.Alternatively, these two further output circuits can also be designed asymmetrically around the ground potential.
Wenigstens ein Betriebsgerät kann mit Ausgangskreisen mit unterschiedlichen Gleichspannungspegeln verbunden sein.At least one operating device may be connected to output circuits having different DC levels.
Ein Ausgangskreis kann dabei beispielsweise für die Bereitstellung der Leuchtmittel-Betriebsleistung und wenigstens ein weiterer Ausgangskreis für die Bereitstellung einer Niedervolt-Spannungsversorgung von Logikbauteilen in einem Betriebsgerät dienen.An output circuit can serve, for example, for the provision of the lamp operating power and at least one further output circuit for the provision of a low-voltage power supply of logic components in a control gear.

In der Zentraleinheit selbst können für Ausgangskreise mit unterschiedlichen Gleichspannungspegeln unterschiedliche Gleichrichter- und/oder PFC-Module vorgesehen sein.In the central unit itself, different rectifier and / or PFC modules can be provided for output circuits with different DC voltage levels.
Gemäß einem weiteren Aspekt der Erfindung ist ein System zur Ansteuerung von Betriebsgeräten für Leuchtmittel vorgesehen, das eine Zentraleinheit aufweist, die eine Gleichrichterschaltung aufweist und mit Wechselspannung (beispielsweise Netzspannung) versorgbar ist. Dabei ist wenigstens ein Betriebsgerät für Leuchtmittel mit der Zentraleinheit über mehrere DC-Ausgangskreise mit unterschiedlichen Spannungspegeln.According to a further aspect of the invention, a system for controlling operating devices for lighting means is provided which has a central unit which has a rectifier circuit and can be supplied with alternating voltage (for example mains voltage). In this case, at least one operating device for lighting means with the central unit via a plurality of DC output circuits with different voltage levels.
Somit kann beispielsweise ein dem Betriebsgerät zugeordnetes Leuchtmittel durch Übertragung eines Ausschaltbefehles über einen der Ausgangskreise ausschaltbar sein, wobei die Spannungsversorgung über einen weiteren Ausgangskreis unverändert beibehalten werden kann.Thus, for example, a lamp associated with the operating device can be switched off by transmitting a Ausschaltungsbefehles via one of the output circuits, wherein the power supply can be maintained unchanged via a further output circuit.
Gemäß weiteren Aspekten bezieht sich die vorliegende Erfindung auch auf Verfahren zur Ansteuerung von Betriebsgeräten für Leuchtmittel.In other aspects, the present invention also relates to methods of driving lighting apparatus.

Je nach Natur der angeschlossenen Leuchtmittel 5, 5' bzw. Sensoren 5" sind die Betriebsgeräte 1, 1', 1" unterschiedlich ausgebildet. Für den Fall, dass eine Gasentladungslampe 5 angesteuert werden soll, ist das entsprechende Betriebsgerät 3 bspw. als elektronisches Vorschaltgerät (EVG) u.a. mit einem Wechselrichter ausgebildet.

Schließlich kann über den Niedervolt-Ausgangskreis 32 auch das den Betriebsgeräten 2 jeweils zugeordnete Leuchtmittel ausgeschaltet werden, wie schematisch durch einen Schalter 36 dargestellt ist. Dadurch, dass das Ausschalten (indirekt) über den Niederspannungs-Ausgangskreis 32 und nicht (direkt) über den Hochspannungs-Ausgangskreis 31 erfolgt, wird das Problem der Funkenstrecke bei geöffnetem Schalter 36 deutlich verringert. Falls also beispielsweise der Niederspannungs-Ausgangskreis 32 die Logikbauteile in dem Betriebsgerät 3 über den jeweiligen Anschluß 35 versorgt, können durch Öffnen des Schalters 36 diese entsprechenden Logikbauteile, beispielsweise die Ansteuerung des Wechselrichters in einem EVG abgeschaltet werden, was wiederum zum Verlöschen der zugeordneten Gasentladungslampe 5 führt.Finally, via the low-
Auch wenn somit das zugeordnete Leuchtmittel, hier die Gasentladungslampen 5, abgeschaltet werden, steht nach wie vor die Betriebsspannung von 400 Volt über den Ausgangskreis 31 zur Verfügung, so dass die entsprechenden Leuchtmittel ausgehend von diesem Standby-Betrieb jederzeit wieder schnell eingeschaltet werden, indem beispielsweise der Schalter 36 wieder geschlossen wird. Es ist anzumerken, dass der mechanische Schalter 36 jederzeit durch eine Übermittlung von entsprechenden Digitalbefehle ersetzt werden kann, die über den Niederspannungs-Ausgangskreis 32 übermittelt werden und am Eingang 35 des Betriebsgeräts beispielsweise durch einen Powerline-Demodulator (nicht dargestellt) ausgelesen und in einen Ansteuerbefehl für eine lokale Steuereinheit in einem Betriebsgerät umgesetzt werden.Even if, therefore, the associated light source, here the

ASICs) in einem Betriebsgerät und/oder als Steuerkreis verwendet werden.In general, the low-voltage output circuit with, for example, 12 V DC can be used in any combination as power supply for light sources (in particular for LEDs), as supply voltage for logic components (eg ASICs) in an operating device and / or as a control circuit.

Somit können Betriebsgeräte, an die unterschiedliche Typen an Leuchtmitteln angeschlossen sind, individuell entsprechend ihren jeweiligen Anforderungen an die Spannungsversorgung versorgt werden. Eine hohe DC-Spannung bietet sich beispielsweise für Gasentladungslampen an, während sich eine niedrige Gleichspannungsversorgung beispielsweise für LED-Leuchtmittel anbietet.Thus, operating devices to which different types of lamps are connected, can be individually supplied according to their respective requirements for the power supply.
