Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels einer Beleuchtungsanlage und eines Betriebsgerätes für einen Busteilnehmer erklärt.The invention will be explained with reference to an embodiment of a lighting system and an operating device for a bus subscriber.

Nachfolgend wird ein Beispiel einer Beleuchtungsanlage BA mit einer zentralen Steuereinheit 12, einem Steuergerät 10, die über das Steuergerät 10 an das Netz gekoppelten Betriebsgeräte 1, 1', 1", 1'x, 1'y und weiteren Steuergeräten 11, 13, 14 erläutert.Below is an example of a lighting system BA with a central control unit 12, a control unit 10, via the control unit 10 to the network coupled operating devices 1, 1 ', 1 ", 1' x , 1 ' y and other control units 11, 13, 14th explained.

Die vorliegende Erfindung kann bei sämtlichen Arten von Betriebsgeräten für Leuchtmittel eingesetzt werden. Dabei ist die Anwendung von ganz verschiedenen Leuchtmitteln möglich, es können insbesondere Gasentladungslampen, Halogenlampen oder auch anorganische oder organische Leuchtdioden eingesetzt werden.The present invention can be applied to all types of lighting apparatus. The use of very different bulbs is possible, it can be used in particular gas discharge lamps, halogen lamps or inorganic or organic light-emitting diodes.

Das Betriebsgeräte 1, 1', 1", 1'x, 1'y, die zentrale Steuereinheit 12 und das Steuergerät 10 sind Bestandteil einer Beleuchtungsanlage BA.The operating devices 1, 1 ', 1 ", 1' x , 1 ' y , the central control unit 12 and the control unit 10 are part of a lighting system BA.

Zusätzlich können weitere Steuergeräte 11, 13, 14 an die Busleitung 21 angeschlossen sein.In addition, further control devices 11, 13, 14 may be connected to the bus line 21.

Die verschiedenen Steuergeräte 11, 13, 14 werden auch als Aktuatoren bezeichnet und können verschiedene Sensoren wie beispielsweise Bewegungs- oder Helligkeitssensoren aber auch durch einen Benutzer steuerbare Aktuatoren wie beispielsweise Schalter, Taster oder auch berührungsempfindliche Bildschirme mit einem Benutzerinterface zur Beleuchtungssteuerung sein.The various control devices 11, 13, 14 are also referred to as actuators and can be various sensors such as motion or brightness sensors but also user-controllable actuators such as switches, buttons or touch-sensitive screens with a user interface for lighting control.

Die Busleitung 21 ist als zweidrahtige Datenleitung ausgebildet, die als Steuerbefehl ein Digitalsignal mit einer niedrigen Gleichspannung überträgt. Über die Busleitung 21 wird beispielweise eine Datenübertragung gemäß DALI Standard übertragen. Die Schnittstellenschaltungen der Betriebsgeräte 1, 1', 1'', 1'x, 1'y, die zentrale Steuereinheit 12 und das Steuergerät 10 sind in der Lage, Steuerbefehle gemäß dem DALI Standard zu empfangen.The bus line 21 is designed as a two-wire data line, which transmits a control signal as a digital signal with a low DC voltage. For example, a data transmission according to the DALI standard is transmitted via the bus line 21. The interface circuits of the operating devices 1, 1 ', 1'',1' x , 1 ' y , the central control unit 12 and the control unit 10 are capable of receiving control commands according to the DALI standard.

Anzumerken ist, dass die Datenübertragung der Steuerbefehle über die Busleitung 21 nicht drahtgebunden erfolgen muß, sondern sie kann beispielsweise drahtlos über eine Funkverbindung oder über eine Power Line Communication (PLC) über das Stromversorgungsnetz 20 übertragen werden.It should be noted that the data transmission of the control commands via the bus line 21 does not have to be wired, but it can be transmitted for example wirelessly via a radio link or via a power line communication (PLC) via the power grid 20.

Für die genannten Übertragungsvarianten existieren jeweils standardisierte Übertragungsverfahren analog zu dem DALI Standard für drahtgebundene Datenübertragung, wobei eine abgeänderte Datenübertragung über die gleiche Busleitung 21 erfolgen kann.Standardized transmission methods exist analogously to the DALI standard for wired data transmission for the transmission variants mentioned, whereby a modified data transmission can take place via the same bus line 21.

Es ist aber auch möglich, dass die Busleitung 21 zur Übertragung von Tastersignalen ausgelegt ist. Die zentrale Steuereinheit 12 kann dabei ein Taster sein, der in einer einfachen Variante bei Betätigung die Busleitung 21 kurzschließt. Der Taster kann aber auch mit Netzspannung versorgt werden und die Busleitung ein mit Netzspannung versorgtes Tastersignal übertragen.But it is also possible that the bus line 21 is designed for the transmission of probe signals. The central control unit 12 may be a button which short-circuits the bus line 21 in a simple variant when actuated. However, the button can also be supplied with mains voltage and the bus line can transmit a button signal supplied with mains voltage.

Die zentrale Steuereinheit 12 kann über die Busleitung 21 einzelne oder mehrere Betriebsgeräte 1 von Leuchtmitteln steuern, wobei sie digitale Steuerbefehle empfangen und auch aussenden kann. Bei einem entsprechenden Ausschaltbefehl auf der Busleitung 21, welcher durch das Steuergerät 10 empfangen und ausgewertet wird, kann das Steuergerät 10 die angeschlossenen Betriebsgeräte 1 vom Netz trennen, um deren Leistungsaufnahme auf 0 zu senken. Es werden dadurch die Betriebsgeräte 1 vom Betriebszustand in einen Ruhezustand überführt. Das Steuergerät 10 überwacht weiterhin die Busleitung 21 auf Steuerbefehle und kann diese abspeichern.The central control unit 12 can control single or multiple operating devices 1 of lighting devices via the bus line 21, wherein they can receive and also send digital control commands. In the case of a corresponding switch-off command on the bus line 21, which is received and evaluated by the control unit 10, the control unit 10 can disconnect the connected operating devices 1 from the grid in order to reduce their power consumption to 0. Thereby, the operating devices 1 are transferred from the operating state to a standby state. The control unit 10 continues to monitor the bus line 21 to control commands and can save them.

Die Netzankopplung und Netztrennung der Betriebsgeräte 1 von der Netzversorgung erfolgt durch einen Netzunterbrecher 5. Dieser Netzunterbrecher 5 kann ein Schalter wie zum Beispiel ein Halbleiterschalter oder ein Relais sein.The grid connection and network separation of the operating devices 1 from the mains supply is effected by a mains breaker 5. This mains breaker 5 may be a switch such as a semiconductor switch or a relay.

Der Netzunterbrecher 5 kann in das Steuergerät 10 integriert sein oder aber durch einen Steuerausgang des Steuergerätes 10 angesteuert werden.The mains breaker 5 can be integrated into the control unit 10 or else be driven by a control output of the control unit 10.

Das Steuergerät 10 kann mehrere unabhängige Netzankopplungen und somit voneinander unabhängige Betriebsgeräte 1 ansteuern, indem es mehrere Netzankopplungen ansteuern kann bzw. integriert hat.The control unit 10 can control a plurality of independent network connections and thus independently of each other operating devices 1 by being able to control or integrate several network connections.

Die voneinander unabhängigen Betriebsgeräte 1 können durch unterschiedliche Adressen voneinander unterschieden werden.The independent operating devices 1 can be distinguished from each other by different addresses.

Die Energieversorgung des Steuergerätes 10 und der Steuergeräte 11, 13, 14 und der zentralen Steuereinheit 12 kann über eine in das Steuergerät 10 integrierte Busversorgung erfolgen. Dabei kann die Busversorgung die Busleitung 21 speisen, indem eine Übertragung nach dem sogenannten ,Active Low' Prinzip angewendet wird. Bei einer solchen Übertragung liegt dauerhaft ein Pegel von beispielsweise 12V an, solange keine Daten übertragen werden. Im Fall einer Datenübertragung wird der Pegel zum Übertragen eines Bit auf einen Pegel unter beispielsweise 2V gezogen wird.The power supply of the control unit 10 and the control units 11, 13, 14 and the central control unit 12 can be effected via a bus supply integrated in the control unit 10. The bus supply can feed the bus line 21 by applying a transmission according to the so-called 'active low' principle. In such a transmission is permanently a level of, for example, 12V, as long as no data is transmitted. In the case of data transmission, the level for transmitting a bit is pulled to a level below 2V, for example.

Auf diese Weise liegt eine dauerhafte Spannung auf der Busleitung 21 an und somit ist eine Versorgung der Steuergeräte 10 und 11 über die Busleitung 21 möglich.In this way, a permanent voltage is applied to the bus line 21 and thus a supply of the control units 10 and 11 via the bus line 21 is possible.

Es kann das Steuergerät 10 über eine eigene Energieversorgung verfügen, die direkt an die Netzversorgung gekoppelt ist.It may have the control unit 10 via its own power supply, which is coupled directly to the mains supply.

Die zentrale Steuereinheit 12 kann den Zustand der Betriebsgeräte 1 über die Busleitung 21 abfragen. Weiterhin kann die zentrale Steuereinheit 12 auch über direkt verbundene Taster oder Schalter, durch eine Schnittstelle zu einem Programmiergerät, durch einen Touchscreen oder andere Einstellmöglichkeiten auch direkt durch einen Benutzer konfiguriert und gesteuert werden. Durch die direkte Steuermöglichkeit kann der Benutzer auch Steuerbefehle wie beispielsweise Helligkeitswerte vorgeben.The central control unit 12 can query the state of the operating devices 1 via the bus line 21. Furthermore, the central control unit 12 can also be directly configured and controlled by a user via directly connected buttons or switches, through an interface to a programming device, through a touchscreen or other adjustment options. Due to the direct control option, the user can also specify control commands, such as brightness values.

Innerhalb der Beleuchtungsanlage BA mit mindestens einem Leuchtmittel können die Leuchtmittel, die durch zumindest ein Betriebsgerät 1, 1', 1", 1'x, 1'y abhängig von Befehlen einer zentralen Steuereinheit 12 angesteuert werden, eine Adresse aufweisen. Bereits bei Auslieferung der Betriebsgeräte 1, 1', 1", 1'x, 1'y kann in den Betriebsgeräte 1, 1', 1", 1'x, 1'y jeweils eine voreingestellte Adresse L abgelegt sein.Within the lighting system BA with at least one light source, the light sources, which are controlled by at least one operating device 1, 1 ', 1 ", 1' x , 1 ' y depending on commands of a central control unit 12, can have an address Operating devices 1, 1 ', 1 ", 1' x , 1 ' y can be stored in the operating devices 1, 1', 1", 1 ' x , 1' y each have a preset address L.

Bei dem in Fig. 2 dargestellten Betriebsgerät 1 weist als zentrale Komponente eine Steuerschaltung 2 auf, welche alle Funktionen der Komponenten des Betriebsgerätes 1 steuert und überwacht. Insbesondere ist die Steuerschaltung 2 als integrierte Schaltung ausgeführt, beispielsweise als ASIC, Microcontroller, PAL oder DSP. Insbesondere wird der Betrieb des Konverters 3 gesteuert und überwacht, insbesondere auch geregelt.

Der Konverter 3 übernimmt sowohl die Aufgabe der korrekten Stromaufnahme aus dem Stromversorgungsnetz 20, welche durch die Bestimmungen des Energieversorgers vorgegeben sein kann.The converter 3 assumes both the task of correct power consumption from the power supply network 20, which may be predetermined by the provisions of the energy supplier.

Diese Aufgabe kann vor allem eine möglichst sinusförmige Stromaufnahme mit möglichst wenigen hochfrequenten Störungen betreffen. Der Konverter 3 kann daher ein sogenanntes Filter zum Vermeiden von hochfrequenten Störungen, die entweder aus dem Stromversorgungsnetz 20 kommen können oder aber durch den Konverter 3 erzeugt wurden, sowie eine Schaltung zur aktiven Leistungsfaktorkorrektur enthalten. Außerdem stellt der Konverter 3 den ordnungsgemäßen Betrieb der Lampe LED sicher. Insbesondere kann er den Strom und / oder die Spannung durch die Lampe LED einstellen oder auch regeln.Above all, this task can involve a sinusoidal current consumption with as few high-frequency disturbances as possible. The converter 3 can therefore contain a so-called filter for avoiding high-frequency disturbances, which can either come from the power supply network 20 or were generated by the converter 3, as well as a circuit for active power factor correction. In addition, the converter 3 ensures the proper operation of the lamp LED. In particular, he can adjust the current and / or the voltage through the lamp LED or regulate.

In einer besonderen Ausführungsform kann der Konverter 3 auch als mehrstufiger Konverter ausgeführt werden, um die verschiedenen Aufgaben der auf die einzelnen Stufen des Konverters 3 aufzuteilen. Vorteilhafterweise wird durch eine Stufe die korrekte Stromaufnahme aus dem Stromversorgungsnetz 20 sichergestellt, eine nachfolgende Stufe steuert den Betrieb der Lampe LED. Das Stromversorgungsnetz 20 kann eine niederfrequente Wechselspannung mit einer Spannung von 230V oder eine Gleichspannung von 24V sein.In a particular embodiment, the converter 3 can also be designed as a multi-stage converter in order to divide the various tasks of the individual stages of the converter 3. Advantageously, the correct current consumption from the power supply network 20 is ensured by a stage, a subsequent stage controls the operation of the lamp LED. The power supply network 20 may be a low-frequency alternating voltage with a voltage of 230V or a DC voltage of 24V.

Abhängig von der Art des Stromversorgungsnetzes 20 kann der Konverter 3 als DC-DC-Wandler oder als AC-DC-Wandler ausgebildet sein. In einer besonders vorteilhaften Ausführungsform kann der Konverter 3 einen Energiespeicher (Cbus) enthalten, dieser kann durch einen Speicherkondensator oder auch eine wiederaufladbare Batterie gebildet werden.Depending on the type of power supply network 20, the converter 3 may be designed as a DC-DC converter or as an AC-DC converter. In a particularly advantageous embodiment, the converter 3 may include an energy store (Cbus), which may be formed by a storage capacitor or a rechargeable battery.

Das Betriebsgerät 1 und das Steuergerät 10 sind Bestandteil eines Beleuchtungssystems BA.The operating device 1 and the control unit 10 are part of a lighting system BA.

Die Steuerschaltung 2 ist weiterhin mit der Schnittstelle 4 verbunden. Die Schnittstelle 4 ist mit der Busleitung 21 verbunden. Über die Busleitung 21 werden die von dem Steuergerät 10 gesendeten Steuerbefehle übertragen. Diese Steuerbefehle werden von der Schnittstelle 4 empfangen und an die Steuerschaltung 2 weitergeleitet. Die Steuerschaltung 2 kann die Steuerbefehle auswerten und abspeichern. Gemäß den übermittelten Steuerbefehlen kann die Steuerschaltung 2 den Betrieb der Lampe LED durch den Konverter 3 steuern.The control circuit 2 is further connected to the interface 4. The interface 4 is connected to the bus line 21. Via the bus line 21, the control commands sent by the control unit 10 are transmitted. These control commands are received by the interface 4 and forwarded to the control circuit 2. The control circuit 2 can evaluate and store the control commands. According to the transmitted control commands, the control circuit 2 can control the operation of the lamp LED by the converter 3.

Die Steuerschaltung 2 kann auch den Betrieb der Lampe LED und des Konverters 3 überwachen und im Falle eines Fehlers oder besonderen Ereignisses dieses Erkennen und über die Schnittstelle 4 und die Busleitung 21 einen entsprechenden Steuerbefehl an das Steuergerät 10 senden. Zusätzlich können weitere Steuergeräte 11 an die Busleitung 21 angeschlossen sein.The control circuit 2 can also monitor the operation of the lamp LED and the converter 3 and in the event of a fault or special event of this detection and via the interface 4 and the bus 21 to send a corresponding control command to the control unit 10.

Über die Busleitung 21 wird beispielweise eine Datenübertragung gemäß DALI Standard übertragen. Die Schnittstelle 4 und das Steuergerät 10 sind in der Lage, Steuerbefehle gemäß dem DALI Standard zu empfangen. Es ist jedoch auch möglich, alternativ zu der Datenübertragung gemäß der standardisierten Übertragung eine Übertragung mit anderen Parametern zu wählen. Durch die Fähigkeit zur Datenübertragung gemäß DALI Standard sowohl des Betriebsgerätes 1 als auch des Steuergerätes 10 kann eine sehr hohe Kompatibilität für die Komponenten des Beleuchtungssystems erzielt werden.For example, a data transmission according to the DALI standard is transmitted via the bus line 21. The interface 4 and the controller 10 are capable of receiving control commands according to the DALI standard. However, it is also possible to choose a transmission with other parameters as an alternative to the data transmission according to the standardized transmission.
