Description

Die vorliegende Erfindung bezieht sich auf den Betrieb von Leuchtmitteln wie beispielsweise Leuchtstofflampen und Gasentladungslampen sowie Leuchtdioden (LEDs). Die Erfindung betrifft insbesondere ein Betriebsgerät oder ein elektronisches Vorschaltgerät ("EVG"), das über eine Schnittstelle zur Ausgabe von Daten verfügt sowie Beleuchtungssysteme mit derartigen Betriebsgeräten.The present invention relates to the operation of light sources such as fluorescent lamps and gas discharge lamps and light-emitting diodes (LEDs). In particular, the invention relates to an operating device or an electronic ballast ("ECG"), which has an interface for outputting data and lighting systems with such operating devices.

Es ist bereits aus dem Stand der Technik bekannt, dass Betriebsgeräte für Leuchtmittel eine digitale Schnittstelle, wie beispielsweise eine DALI (Digital Addressable Lighting Interface) -Schnittstelle, aufweisen. Das DALI ist ein Kommunikationsprotokoll zur Steuerung von digitalen lichttechnischen Betriebsgeräten über einen entsprechenden digitalen Bus bzw. Leitung. Jedes Betriebsgerät, das nun über eine DALI-Schnittstelle an einem derartigen digitalen Bus angeschlossen ist, kann von einer zentralen Steuereinheit angesteuert werden.It is already known from the prior art that operating devices for lighting means have a digital interface, such as a DALI (Digital Addressable Lighting Interface) interface. The DALI is a communication protocol for controlling digital lighting control gear via a corresponding digital bus or line. Each operating device, which is now connected via a DALI interface to such a digital bus, can be controlled by a central control unit.

Der digitale DALI-Bus ist auch bidirektional und ermöglicht darum einen bidirektionalen Datenaustausch zwischen dieser zentralen Steuereinheit und dem einzelnen Betriebsgerät. Somit kann die zentrale Steuereinheit beispielsweise den Status eines am digitalen Bus angeschlossenen Betriebsgeräts oder eines von dem Betriebsgerät gesteuerten Leuchtmittels abfragen.The digital DALI bus is also bidirectional and therefore allows bi-directional data exchange between this central control unit and the individual control gear. Thus, the central control unit, for example, the status of an am Interrogate the digital bus connected to the operating device or a light source controlled by the operating device.

Nachteilig bei dieser bekannten DALI-Schnittstelle ist es aber, dass die Information über den Status des Betriebsgeräts nur zentral und nur über den digitalen Bus abgefragt werden kann. Eine derartige Abfrage ist übrigens nicht möglich, wenn das Betriebsgerät keine DALI-Schnittstelle aufweist.A disadvantage of this known DALI interface, however, is that the information about the status of the operating device can only be queried centrally and only via the digital bus. Incidentally, such a query is not possible if the operating device has no DALI interface.

Weiterhin ist es bereits aus der EP 0 965 252 B1 grundsätzlich bekannt, dass ein Betriebsgerät bzw. ein elektronisches Vorschaltgerät zum Betreiben einer Lampe eine Anschlussvorrichtung aufweist, an die ein Lichtsensor zur Überwachung der Helligkeit eines bestimmten räumlichen Bereichs anschließbar ist.Furthermore, it is already out of the EP 0 965 252 B1 basically known that an operating device or an electronic ballast for operating a lamp has a connection device to which a light sensor for monitoring the brightness of a specific spatial area can be connected.

Die Lampe, deren Helligkeit von dem Lichtsensor erfasst wird, wird von diesem Betriebsgerät entsprechend den Helligkeits-Istwerten gesteuert bzw. die Beleuchtung wird gedimmt.The light sensor used for brightness control detects brightness actual values in a region illuminated by a lamp. These brightness actual values are fed to the operating device via this connection device. The lamp whose brightness is detected by the light sensor is controlled by this operating device according to the brightness actual values or the lighting is dimmed.

Allerdings wird diese Mess-Anschlußvorrichtung zum Anschluß von Lichtsensoren bzw. helligkeitsabhängigen Widerständen benutzt und kann nicht zur Abfrage von Informationen aus dem Betriebsgerät eingesetzt werden.However, this measuring terminal device is used to connect light sensors or brightness-dependent resistors and can not be used to query information from the operating device.

Fig. 1 ist eine schematische Darstellung eines Ausführungsbeispiels eines Systems 1 gemäß der vorliegenden Erfindung. Das System 1 umfasst im Wesentlichen ein Betriebsgerät 2 zum Betreiben von einer oder mehreren Lampen 3 oder allgemein "Leuchtmitteln", wie bspw. LEDs oder Gasentladungslampen. Das Betriebsgerät 2 kann insbesondere ein elektronisches Vorschaltgerät 2 für mindestens eine Lampe 3 sein, insbesondere für mindestens eine Leuchtstofflampe wie beispielsweise eine Gasentladungslampe. Fig. 1 is a schematic representation of an embodiment of a system 1 according to the present invention.

In this case, the operating device 2 can be designed, for example, as a light-emitting diode converter.

Das gezeigte elektronische Vorschaltgerät 2 weist Eingänge 4a und 4b einer Lichtsensor-Schnittstelle 5, sowie zwei Steuereingänge 6a und 6b zum Anschluß eines vorzugsweise digitalen Steuerbus bzw. Steuer-Leitungen 7a und 7b, auf.The electronic ballast 2 shown has inputs 4a and 4b of a light sensor interface 5, and two control inputs 6a and 6b for connecting a preferably digital control bus or control lines 7a and 7b, on.

Die Eingänge 4a, 4b und die Steuereingänge 6a und 6b sind an eine Steuervorrichtung 8 des elektronischen Vorschaltgeräts 2 angeschlossen, das in bekannter Weise zur Steuerung oder Regelung der Lampenleistung dient.The inputs 4a, 4b and the control inputs 6a and 6b are connected to a control device 8 of the electronic ballast 2, which serves in a known manner for controlling or regulating the lamp power.

An die Lichtsensor-Schnittstelle 5 des elektronischen Vorschaltgeräts 2 kann ein externer Widerstand angeschlossen werden. Insbesondere kann ein Lichtsensor oder Fotowiderstand 9 an die Lichtsensor-Schnittstelle 5 angeschlossen werden. Ein derartiger bekannter Lichtsensor 9 ist dazu ausgelegt, die Helligkeit des darauf einfallenden Lichts zu messen.To the light sensor interface 5 of the electronic ballast 2, an external resistor can be connected. In particular, a light sensor or photoresistor 9 can be connected to the light sensor interface 5. Such a known light sensor 9 is designed to measure the brightness of the incident light thereon.

Ist, wie in Fig. 1 gezeigt, ein Lichtsensor 9 an die Sensor-Schnittstelle 5 tatsächlich angeschlossen, so können die von dem Lichtsensor gelieferten Helligkeits-Istwerte eines vom Lichtsensor überwachten Bereichs dem elektronischen Vorschaltgerät 2 zugeführt werden, wobei die Steuervorrichtung 8 des elektronischen Vorschaltgerät 2 dann abhängig von den zugeführten Helligkeits-Istwerten die zur Beleuchtung des überwachten Bereiches dienende Lampe dimmen kann.Is, as in Fig. 1 a light sensor 9 is actually connected to the sensor interface 5, the brightness actual values of a region monitored by the light sensor can be supplied to the electronic ballast 2, wherein the control device 8 of the electronic ballast 2 then depends on the supplied Brightness actual values can dim the serving for illumination of the monitored area lamp.

Die Eingänge 4a, 4b der Sensor-Schnittstelle 5 können alternativ für den Anschluss eines Potentiometers (nicht gezeigt) benutzt werden. Die Verwendung des Potentiometers ermöglicht ein manuelles Steuern oder Dimmen der Lampe 3, da die Helligkeit der Lampe 3 in Abhängigkeit vom gewählten Widerstand des Potentiometers 11 gesteuert wird.The inputs 4a, 4b of the sensor interface 5 can alternatively be used for the connection of a potentiometer (not shown).

Dieses Umschalten zwischen Sensor-Modus und Abfrage-Modus, d.h. zwischen dem Empfang von Dimm- oder Lichtsensor-Informationen und dem Senden von digitalen Informationen über die Lichtsensor-Schnittstelle, wird vorzugsweise von der Steuervorrichtung 8 über eine entsprechende Leitung 10 vorgenommen.This switching between sensor mode and polling mode, i. between the reception of dimming or light sensor information and the transmission of digital information via the light sensor interface, is preferably carried out by the control device 8 via a corresponding line 10.

Einschalten eines bestimmten Modus für die Schnittstelle 5 zugeführt werden.Via the control inputs 6a, 6b, the ballast 2 can either be supplied with specific dimming setpoint values for the lamp 3 or a signal for switching or switching on a specific mode for the interface 5.

Fig. 3 zeigt alternativ, dass auch von Hand, d.h. manuell von einem Benutzer, der Modus der mechanischen Sensor-Schnittstelle 5 umgeschaltet werden kann. Die entsprechenden Befehle für die Steuervorrichtung 8 zur Einstellung des einen oder des anderen Modus können vom Benutzer über eine Taste 11 am Betriebsgerät 2 oder am elektronischen Vorschaltgerät ausgelöst. Fig. 3 shows alternatively that manual mode, ie manually by a user, the mode of the mechanical sensor interface 5 can be switched. The corresponding commands for the control device 8 for setting the one or the other mode can from the User triggered via a button 11 on the operating device 2 or the electronic ballast.

Die Taste 11 stellt nur eine Ausführungsform der Erfindung dar. Gemäß alternativen Ausführungsformen können andere bekannte Benutzerschnittstellen eingesetzt werden.Key 11 represents only one embodiment of the invention. In alternative embodiments, other known user interfaces may be employed.

Es ist gemäß einer weiteren nicht gezeigten Ausführungsform auch vorgesehen, dass die Taste 11 oder die alternative Benutzerschnittstelle nicht mit der Steuervorrichtung 8, sondern direkt mit der Sensor-Schnittstelle 5 verbunden ist, um den Sensor- oder den Abfrage-Modus einstellen zu können.It is also provided according to another embodiment, not shown, that the key 11 or the alternative user interface is not connected to the control device 8, but directly to the sensor interface 5 in order to set the sensor or the polling mode can.

Im Abfrage-Modus kann die Sensor-Schnittstelle 5, die eigentlich die Eingangssignale vom Lichtsensor bewerten soll, Signale und insbesondere DALI-Signale bereitstellen. Externe Geräte sind dann in der Lage, aus der Sensor-Schnittstelle 5 Informationen gemäß dem DALI-Standard zu lesen bzw. abzufragen.In interrogation mode, the sensor interface 5, which is actually intended to evaluate the input signals from the light sensor, can provide signals and in particular DALI signals. External devices are then able to from the sensor interface 5 to read or retrieve information according to the DALI standard.

Fig. 4 zeigt ein erfindungsgemäßes Betriebsgerät 2 mit selektiv umschaltbarer Sensor-Schnittstelle 5 zum Auslesen von Daten durch ein externes Auslesegerät 12. Fig. 4 shows an inventive operating device 2 with selectively switchable sensor interface 5 for reading data by an external reader 12th

Das Auslesegerät 12 ist vorzugsweise ein DALI-Auslesegerät und die vom Betriebsgerät ausgelesenen Informationen entsprechend nach dem DALI Standard zu dekodieren.The reader 12 is preferably a DALI reader and the information read by the operating device according to the DALI standard to decode.

Das Auslesegerät 12 dient also als eine Art Diagnosegerät zum Auslesen von Daten.The reader 12 thus serves as a kind of diagnostic device for reading data.

Entsprechend wird vom Auslesegerät 12 eine Versorgungsspannung an der Sensor-Schnittstelle 5 angelegt. Die Sensor-Schnittstelle 5 weist also eine Spannung von beispielsweise 12 V auf, die von einer Moduliereinheit 13 des Betriebsgeräts 8 moduliert und anschließend von einer Demoduliereinheit 14 des Auslesegeräts 12 demoduliert werden kann.Accordingly, the read-out device 12 applies a supply voltage to the sensor interface 5. The sensor interface 5 thus has a voltage of, for example, 12 V, which can be modulated by a modulating unit 13 of the operating device 8 and subsequently demodulated by a demodulating unit 14 of the read-out device 12.

Die Modulierung durch das Betriebsgerät 2 kann dadurch erfolgen, dass die beiden Anschlüsse 4a, 4b der Sensor-Schnittstelle 5 in bestimmter Art und Weise kurzgeschlossen und dann vom Auslesegerät 12 beispielsweise als DALI Signal ausgewertet werden.The modulation by the operating device 2 can take place in that the two terminals 4a, 4b of the sensor interface 5 are short-circuited in a certain manner and then evaluated by the read-out device 12, for example as a DALI signal.

Die gewünschten Auslese-Informationen werden also moduliert, in dem die Sensor-Schnittstelle 5 selektiv vom Betriebsgerät 2 kurzgeschlossen wird. Wird nun diese Sensor-Schnittstelle 5 kurzzeitig auf Null gezogen, so wird dies vom Auslesegerät 12 erfasst und als entsprechendes Bit oder Symbol interpretiert.The desired readout information is thus modulated, in which the sensor interface 5 is selectively short-circuited by the operating device 2. Will now this sensor interface 5 briefly pulled to zero, this is detected by the reader 12 and interpreted as a corresponding bit or symbol.
