Description

Die vorliegende Erfindung bezieht sich auf den Betrieb von Leuchtmitteln wie beispielsweise Leuchtstofflampen und Gasentladungslampen. Die Erfindung betrifft insbesondere ein Betriebsgerät oder ein elektronisches Vorschaltgerät, das über eine Eingangsschnittstelle verfügt, an welche ein Lichtsensor zur Überwachung der Helligkeit anschließbar ist, sowie Verfahren zur Benutzung dieser Eingangsschnittstelle.The present invention relates to the operation of lamps such as fluorescent lamps and gas discharge lamps. In particular, the invention relates to an operating device or an electronic ballast which has an input interface to which a light sensor for monitoring the brightness can be connected, and to methods for using this input interface.

Es ist bereits aus der EP 0 965 252 B1 grundsätzlich bekannt, dass ein elektronisches Vorschaltgerät zum Betreiben einer Lampe eine Anschlussvorrichtung aufweist, an die ein Lichtsensor zur Überwachung der Helligkeit eines bestimmten räumlichen Bereichs anschließbar ist. Der zur Helligkeitsregelung eingesetzte Lichtsensor erfasst Helligkeits-Istwerte in einem von einer Lampe beleuchteten Bereich. Diese Helligkeits-Istwerte werden über diese Anschlussvorrichtung dem Betriebsgerät zugeführt. Die Lampe, deren Helligkeit von dem Lichtsensor erfasst wird, wird von diesem Betriebsgerät entsprechend den Helligkeits-Istwerten gesteuert bzw. die Beleuchtung wird gedimmt.It is already out of the EP 0 965 252 B1 basically known that 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. 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.

Parallel zu dieser ersten Anschlussvorrichtung besitzt das elektronische Vorschaltgerät weitere Anschlüsse zum Empfang von externen Steuerinformationen bspw. über eine Busleitung. Dem elektronischen Vorschaltgerät können derart verschiedene Informationen bzw. Befehle zugeführt werden, wie beispielsweise externe Dimm-Sollwerte. Weiterhin können über die Steueranschlüsse Einschalt- bzw. Ausschalt-Befehle für das elektronische Vorschaltgerät übermittelt werden.Parallel to this first connection device has the electronic ballast further connections to Reception of external control information, for example via a bus line. The electronic ballast can be supplied with various information or commands such as external dimming setpoints. Furthermore, switch-on or switch-off commands for the electronic ballast can be transmitted via the control connections.

Festzuhalten bleibt, dass diese Mess-Anschlußvorrichtung zum Anschluß von Lichtsensoren bzw. helligkeitsabhängigen Widerständen benutzt wird. Falls ein Lichtsensor am Gerät angeschlossen ist, wird dies vom Betriebsgerät überprüft und erkannt, so dass die Helligkeit der Lampe entsprechend dem Sensorwert eingestellt bzw. gedimmt werden kann. Die externe Steuerinformation bzgl. der Helligkeit der Lampe werden in diesem Falle für den Betrieb der Lampe nicht berücksichtigt.It should be noted that this measuring terminal device is used to connect light sensors or brightness-dependent resistors. If a light sensor is connected to the device, this is checked by the operating device and detected, so that the brightness of the lamp can be adjusted or dimmed according to the sensor value. The external control information regarding the brightness of the lamp are not taken into account in this case for the operation of the lamp.

Falls kein Lichtsensor an das elektronische Vorschaltgerät angeschlossen sein sollte, kann dagegen das Betriebsgerät über die weiteren digitalen Steueranschlüsse wie beispielsweise DALI- oder DSI-Anschlüsse gesteuert werden. Aufgrund der niedrigen Signalübertragungsrate von derartigen digitalen Anschlüsse bzw. Schnittstellen können angeschlossene Lampen mittels externen Steuerinformationen auf sich schnell verändernde Helligkeits-Istwerte nicht gesteuert werden. Daher ist es nach diesem Stand der Technik nicht möglich, Lichteffekte mit sehr schnellen Lichtänderungen zu realisieren.If no light sensor should be connected to the electronic ballast, however, the operating device can be controlled via the other digital control connections such as DALI or DSI connections. Due to the low signal transmission rate of such digital connections or interfaces, connected lamps can not be controlled by means of external control information to rapidly changing brightness actual values. Therefore, it is not possible according to this prior art to realize lighting effects with very fast light changes.

Die Erfindung hat sich dementsprechend zur Aufgabe gesetzt, eine verbesserte Technik zum Betrieb einer Lampe bereit zu stellen, womit auch schnelle Lichtänderungen realisierbar sind.The invention has accordingly set itself the task of providing an improved technique for operating a lamp, which also fast light changes can be realized.

In particular, a light sensor for brightness control, a potentiometer for dimming, a resistor for addressing, or an IR (infrared) sensor or light sensor for data transmission come into question as a passive component.

Das Potentiometer kann zum manuellen Dimmen und/oder Ein- und Ausschalten des Leuchtmittels eingesetzt werden.The potentiometer can be used for manual dimming and / or switching the light bulb on and off.

Das Betriebsgerät kann insbesondere automatisch erkennen, ob an den Schnittstellen-Eingang ein Lichtsensor oder ein Potentiometer angeschlossen ist.In particular, the operating device can automatically detect whether a light sensor or a potentiometer is connected to the interface input.

Die automatische Erkennung zwischen Lichtsensor und Potentiometer kann folgende Schritte aufweisen: das Betriebsgerät führt mindestens eine Helligkeitsänderung des zugeordneten Leuchtmittels durch, und bei Änderungen des über den Schnittstellen-Eingang empfangenen Signals wird auf einen Lichtsensor geschlossen, sonst auf ein Potentiometer.The automatic detection between the light sensor and the potentiometer can have the following steps: the operating device performs at least one change in brightness of the associated light source, and changes to the signal received via the interface input, a light sensor is closed, otherwise to a potentiometer.

Die Umschaltung zwischen einem passiven und aktiven Modus im Falle eines passiven bzw. aktiven Signals kann über einen digitalen Steueranschluss vorgenommen werden, insbesondere über einen DALI- oder DMX-Steueranschluss.The switching between a passive and active mode in the case of a passive or active signal can be made via a digital control connection, in particular via a DALI or DMX control connection.

Gemäß einem zweiten Beispiel ist ein Verfahren zum Betreiben eines Betriebsgeräts für Leuchtmittel vorgesehen, insbesondere nach dem ersten Beispiel, wobei das Betriebsgerät einen ersten Schnittstellen-Eingang zum Anschluss eines Lichtsensors und einen zweiten Steuereingang zum Empfangen von Steuerinformationen aufweist.

Gemäß einem weiteren Beispiel ist ein System zum Betreiben von mindestens einem Leuchtmittel vorgesehen, aufweisend ein Betriebsgerät zur Ansteuerung des Leuchtmittels. Das Betriebsgerät weist einen ersten Schnittstellen-Eingang zum Anschluss eines Lichtsensors und einen zweiten Steuereingang zum Empfangen von Steuerinformationen auf.

Fig. 1 ist eine schematische Darstellung eines Beispiels eines Systems 1. Das System 1 umfasst im wesentlichen ein Betriebsgerät 2 zum Betreiben von einer oder mehreren Lampen 3. Das Betriebsgerät 2 kann insbesondere ein elektronisches Vorschaltgerät 2 für mindestens eine Lampe 3 sein, insbesondere für mindestens eine Leuchtstofflampe wie beispielsweise eine Gasentladungslampe. Die Leuchtmittel können aber bspw. auch Leuchtdioden sein. Fig. 1 is a schematic representation of an example of a system 1. The system 1 essentially comprises an operating device 2 for operating one or more lamps 3. The operating device 2 may be in particular an electronic ballast 2 for at least one lamp 3, in particular for at least one fluorescent lamp such for example, a gas discharge lamp. However, the bulbs may also be, for example, light-emitting diodes.

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.The inputs 4a, 4b and the control inputs 6a and 6b are connected to a control device 8 of the electronic ballast 2.

An die Lichtsensor-Schnittstelle 5 des elektronischen Vorschaltgeräts 2 kann ein externer Widerstand angeschlossen werden. Insbesondere kann ein Lichtsensor oder Fotowiderstand an die Lichtsensor-Schnittstelle 5 angeschlossen werden. Ein derartiger bekannter Lichtsensor (nicht gezeigt) 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 be connected. In particular, a light sensor or photoresistor can be connected to the light sensor interface 5. Such a known light sensor (not shown) is designed to measure the brightness of the light incident thereon.

Ist ein Lichtsensor 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.If a light sensor 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, the control device 8 of the electronic ballast 2 then being dependent on the supplied brightness actual values can dim the serving for illumination of the monitored area lamp.

Wie in Figur 1 ersichtlich ist im System 1 eine analoge oder digitale Signalquelle an die zum Empfang von Helligkeitswerten gedachte Sensor-Schnittstelle 5 angeschlossen.As in FIG. 1 an analogue or digital signal source is connected in the system 1 to the sensor interface 5 intended for receiving brightness values.

Die passive Sensor-Schnittstelle 5 wird also dazu benutzt, dem elektronischen Vorschaltgerät 2 ein von einer oder mehreren Signalquellen 9 erzeugtes aktives Eingangssignal über die Eingänge 4a, 4b zuzuführen.The passive sensor interface 5 is thus used to supply the electronic ballast 2 with an active input signal generated by one or more signal sources 9 via the inputs 4a, 4b.

Die Signalquelle 9 kann entweder analoge oder digitale Signale liefern, wobei im letzteren Fall das elektronische Vorschaltgerät 2 dann zusätzlich zu den Steuereingängen 6a, 6b über eine zweite digitale Schnittstelle verfügt.The signal source 9 can provide either analog or digital signals, in which latter case the electronic ballast 2 then has a second digital interface in addition to the control inputs 6a, 6b.

Diese zweite digitale Schnittstelle kann als eine DSI-oder vorzugsweise als eine DALI- oder DMX-Schnittstelle aufgebaut werden. DSI (Digital Signal Interface), DALI (Digital Addressable Lighting Interface) und DMX (Digital Multiplex) sind bekannte Steuerprotokolle zum Steuern oder Dimmen von digitalen lichttechnischen Betriebsgeräten wie z.B. elektronischen Vorschaltgeräten. Das digitale DMX-Steuerprotokoll wird zudem insbesondere in der Bühnentechnik zur Steuerung von Dimmern, intelligenten Scheinwerfern und Effektgeräten angewandt.This second digital interface can be constructed as a DSI or, preferably, a DALI or DMX interface. DSI (Digital Signal Interface), DALI (Digital Addressable Lighting Interface) and DMX (Digital Multiplex) are well-known control protocols for controlling or dimming digital lighting control gear such as electronic ballasts. The digital DMX control protocol is also used in stage technology to control dimmers, intelligent headlamps and effects units.

Die Signalquelle 9 kann auch analoge Signale liefern, wobei in dem Falle vorzugsweise Effektgeräte eingesetzt werden können. Solche Effektgeräte umfassen u.a. Lichtorgeln, Theatereffekte, schnelle Lauflichter, sowie Blitz- und Blinklichter. Auch einfache Quellen, die mittels statischem oder vom Benutzer veränderbarem Einstellelement versehen sind, lassen sich als analoge Signalquelle 9 verwenden. Weitere Beispiele von analogen Signalquellen 9 sind insbesondere Signalgeneratoren, die Signalformen erzeugen beziehungsweise mit anderen Signalen modulieren können. Es werden von derartigen Signalgeneratoren Signalformen erzeugt bzw. moduliert wie beispielsweise Sinus, Rechteck, Dreieck, Pulse oder andere Signalformen mit vorzugsweise weitem Frequenzbereich.The signal source 9 can also provide analog signals, in which case preferably effect devices can be used. Such effect devices include i.a. Light organs, theatrical effects, fast running lights, as well as flash and flashing lights. Even simple sources, which are provided by means of static or user-adjustable setting, can be used as an analog signal source 9. Further examples of analog signal sources 9 are, in particular, signal generators which can generate signal shapes or modulate them with other signals. Signal generators are generated or modulated by such signal generators, such as sine, rectangle, triangle, pulses or other signal forms, preferably with a wide frequency range.

Anwendungen von einem solchen System 1 mit analoger Signalquelle 9 sind vielfältig. So kann z.B. eine Anordnung von drei im Kreis vorgesehenen Leuchtsystemen 1 das Drehfeld eines Dreiphasennetzes sichtbar machen.Applications of such a system 1 with analog signal source 9 are diverse. Thus, e.g. an arrangement of three provided in the circle lighting systems 1 make the rotating field of a three-phase network visible.

Als Signalquelle 9 lässt sich ebenfalls ein Erschütterungssensor, ein Mikrofon oder ein Drucksensor verwenden. Mithilfe eines geeigneten Verstärkers ist somit die Lampe 3 in Abhängigkeit von Geräuschen oder von einem Druck steuerbar. Somit ist auch eine Beleuchtungsalarmanlage einfach zu realisieren.As a signal source 9 can also be a vibration sensor, a microphone or a pressure sensor use. With the aid of a suitable amplifier, the lamp 3 can thus be controlled as a function of noise or of a pressure. Thus, a lighting alarm system is easy to implement.

Das Beleuchtungssystem 1 kann entweder ein oder mehrere Leuchtmittel 3 aufweisen, die auch verschiedene Farben haben können. Mehrere Beleuchtungssysteme können auch kombiniert werden.The lighting system 1 can either have one or more light sources 3, which can also have different colors. Several lighting systems can also be combined.

Falls dem elektronischen Vorschaltgerät 2 analoge Signale über die Sensor-Schnittstelle 5 zugeführt werden, dann können auch verschiedene solcher Signalquellen 9 kombiniert werden. Es ist ebenfalls vorgesehen, dass nur eine analoge Signalquelle 9 mehrere elektronische Vorschaltgeräte 2 mit einem aktiven Signal steuern. Bei Verwendung beispielsweise einer Lichtorgel oder eines anderen Effektgerätes kann so mit einer Reihe von Betriebsgeräten 2 die mit unterschiedlichen Leuchtmitteln bestückt sind, eine praktisch unendliche Zahl von Effekten erzielt werden.If the electronic ballast 2 analog signals are supplied via the sensor interface 5, then also different such signal sources 9 can be combined. It is also envisaged that only one analog signal source 9 control a plurality of electronic ballasts 2 with an active signal. When using, for example, a light organ or another effect device, a practically infinite number of effects can be achieved with a number of operating devices 2 which are equipped with different light sources.

Wie bereits erwähnt, ist es gemäß Beispiel des Beleuchtungssystems 1 vorgesehen, eine digitale Signalquelle 9 an die Eingänge 4a, 4b anzuschließen.As already mentioned, it is provided according to the example of the illumination system 1 to connect a digital signal source 9 to the inputs 4a, 4b.

Zwischen der Sensor-Schnittstelle 5 und der Signalquelle 9 kann vorzugsweise ein Optokoppler 10 vorgesehen werden, zur elektrischen Isolierung der Ein- und Ausgangsstromkreise des elektronischen Vorschaltgeräts 2 bzw. der Signalquelle 9. Durch die Verwendung des Optokopplers 10 kann also eine Potentialtrennung zwischen elektronischem Vorschaltgerät 2 und Signalquelle 9 erreicht werden, so dass die Signalleitungen von der Signalquelle 9 bis zur Sensor-Schnittstelle 5 theoretisch beliebig lang sein können. Der Optokoppler 10 sollte allerdings nicht zu weit von der Sensor-Schnittstelle 5 angeordnet sein, vorzugsweise maximal ein Meter Leitungslänge und 50 cm Abstand vom elektronischen Vorschaltgerät 2 zur Sensor-Schnittstelle 5.Between the sensor interface 5 and the signal source 9, an optocoupler 10 can be provided, for the electrical isolation of the input and output circuits of the electronic ballast 2 and the signal source 9. Thus, the use of the opto-coupler 10 can provide potential separation between the electronic ballast 2 and signal source 9 can be achieved, so that the signal lines from the signal source 9 to the sensor interface 5 can theoretically be of any desired length. However, the optocoupler 10 should not be too far from the sensor interface. 5 be arranged, preferably a maximum of one meter cable length and 50 cm distance from the electronic ballast 2 to the sensor interface. 5

Die Steueranschlüsse 6a, 6b dienen zum Empfang von externen digitalen Steuerinformationen gemäß beispielsweise einem DALI, DSI oder DMX-System.The control terminals 6a, 6b serve to receive external digital control information according to, for example, a DALI, DSI or DMX system.

In einer weiteren Ausführungsform ist das elektronische Vorschaltgerät 2 derart konfiguriert, dass über die Steuereingänge 6a, 6b ein digitales Steuersignal entweder den normalen Sensormodus, in dem ein passives Bauelement wie beispielsweise ein Lichtsensor an die Sensor-Schnittstelle 5 angeschlossen ist, oder den aktiven Modus aktivieren kann, wobei im letzteren Modus ein aktives Signal von der analogen oder digitalen Signalquelle 9 über die Sensor-Schnittstelle 5 übermittelt wird.In a further embodiment, the electronic ballast 2 is configured such that via the control inputs 6a, 6b, a digital control signal activates either the normal sensor mode in which a passive component such as a light sensor is connected to the sensor interface 5 or the active mode can, wherein in the latter mode, an active signal from the analog or digital signal source 9 via the sensor interface 5 is transmitted.

Über die Steuereingänge 6a, 6b können dem Vorschaltgerät 2 also entweder bestimmte Dimm-Sollwerte für die Lampe 3 oder ein Signal zur Aktivierung bzw. Deaktivierung des passiven oder des aktiven Modus zugeführt werden. Im ersten Fall wird die Helligkeit der Lampe 3 gemäß den über die Steuereingänge 6a, 6b empfangenen Dimm-Sollwerten gesteuert. Im passiven oder aktiven Modus wird die Helligkeit der Lampe 3 entsprechend dem an der Sensor-Schnittstelle 5 bereitgestellten Signal geregelt bzw. gesteuert.Via the control inputs 6a, 6b, the ballast 2 can therefore be supplied with either specific dimming setpoint values for the lamp 3 or a signal for activating or deactivating the passive or active mode. In the first case, the brightness of the lamp 3 is controlled according to the dimming setpoints received via the control inputs 6a, 6b. In the passive or active mode, the brightness of the lamp 3 is controlled in accordance with the signal provided at the sensor interface 5.

In einem System bestehend aus mehreren Vorschaltgeräten 2 kann somit ein Teil der Vorschaltgeräte über Dimm-Befehle direkt gesteuert werden, während ein anderer Teil der Vorschaltgeräte an einem von einer Signalquelle 9 angesteuerten Lichtspiel teilnehmen kann.In a system consisting of several ballasts 2 thus part of the ballasts can be controlled directly via dimming commands, while another part of the ballasts can participate in one controlled by a signal source 9 play of light.

Weiterhin ist es gemäß einer weiteren Ausführungsform vorgesehen, dass das analoge oder digitale aktive Signal der Signalquelle 9 im elektronischen Vorschaltgerät 2 einer Filterung oder Veränderung zugeführt wird. Diese Filterung wird vorzugsweise von einer Software durchgeführt, und zwar bevor die Lampe 3 von der Steuerungsvorrichtung 8 angesteuert wird. Die Art der Filterung und Veränderung sowie verschiedene variable Parameter der Filterung können dann über die Steueranschlüsse 6a, 6b bestimmt werden.Furthermore, it is provided according to a further embodiment, that the analog or digital active signal of the signal source 9 in the electronic ballast 2 of a filtering or change is supplied. This filtering is preferably performed by software, before the lamp 3 is controlled by the control device 8. The type of filtering and variation as well as various variable parameters of the filtering can then be determined via the control terminals 6a, 6b.

Figur 2 zeigt ein weiteres Ausführungsbeispiel eines Beleuchtungssystems 1' gemäß der vorliegenden Erfindung. FIG. 2 shows a further embodiment of a lighting system 1 'according to the present invention.

Die Eingänge 4a, 4b der Sensor-Schnittstelle 5 werden hier für den Anschluss eines Potentiometers 11 benutzt. Die Verwendung des Potentiometers 11 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 are used here for the connection of a potentiometer 11. The use of the potentiometer 11 allows manual control or dimming of the lamp 3, since the brightness of the lamp 3 is controlled in dependence on the selected resistance of the potentiometer 11.

Die Helligkeit der Lampe 3 kann dadurch auch deutlich schneller als mit einem Lichtsensor geändert werden. Mit einem angeschlossenen Lichtsensor führt das elektronische Vorschaltgerät 2 nämlich eine langsame Helligkeitsänderung durch. Durch das Einsetzen des Potentiometers 11 können dagegen schnellere Helligkeitsänderungen vom elektronischen Vorschaltgerät 2 durchgeführt werden, die vorzugsweise an die Reaktionszeiten handelsüblicher Dimmer angepasst werden können.The brightness of the lamp 3 can thereby be changed significantly faster than with a light sensor. With a connected light sensor, the electronic ballast 2 performs a slow change in brightness. By inserting the potentiometer 11, however, faster brightness changes can be performed by the electronic ballast 2, which can be preferably adapted to the reaction times of commercial dimmers.

Im Ausführungsbeispiel der Figur 2 können die Eingänge 4a, 4b zum Anschluss des Potentiometers 11 dienen, wobei dieses Potentiometer 11 beispielsweise ein manuelles Dimmen sowie auch ein Ein- bzw. Ausschalten der Lampe 3 ermöglichen kann. Dieses Ausführungsbeispiel kann in existierenden Lampensystemen insbesondere Stehleuchten eingesetzt werden, in dem die bestehende Sensorschnittstelle 5 zum Anschluss eines Potentiometers 11 benutzt wird. Somit ist auf einfacher Weise eine schnelle externe Lichtsteuerung realisierbar.In the embodiment of FIG. 2 the inputs 4a, 4b serve to connect the potentiometer 11, wherein This potentiometer 11, for example, a manual dimming and also enable or disable the lamp 3 can. This embodiment can be used in existing lamp systems, in particular floor lamps, in which the existing sensor interface 5 is used to connect a potentiometer 11. Thus, a fast external light control can be realized in a simple manner.

Das Beleuchtungssystem 1' kann demnach im passiven Modus, der durch den Anschluss eines passiven elektronischen oder optoelektronischen Bauelements an die Eingänge 4a, 4b gekennzeichnet ist, wahlweise mit einem Lichtsensor oder mit einem Potentiometer 11 bestückt werden.Accordingly, the illumination system 1 'can optionally be equipped with a light sensor or with a potentiometer 11 in the passive mode, which is characterized by the connection of a passive electronic or optoelectronic component to the inputs 4a, 4b.

Das elektronische Vorschaltgerät 2 kann z.B. via ein entsprechendes Signal über die Steuereingänge 6a, 6b oder via die Betätigung eines Schalters erkennen, ob ein Lichtsensor oder ein Potentiometer 11 angeschlossen ist.The electronic ballast 2 may e.g. recognize via a corresponding signal via the control inputs 6a, 6b or via the operation of a switch, if a light sensor or a potentiometer 11 is connected.

Das elektronische Vorschaltgerät 2 kann aber auch automatisch detektieren, ob ein Potentiometer 11 zum manuellen Dimmen oder Ein-/Ausschalten eingesetzt ist. Zunächst veranlasst das elektronische Vorschaltgerät 2 eine Helligkeitsänderung oder Dimmen der angeschlossenen Lampe 3, und überprüft gleichzeitig, ob sich der Widerstandswert an der Sensorschnittstelle 5 ändert. Wenn sich dieser Widerstandswert ändert, schließt das elektronische Vorschaltgerät 2 darauf, dass ein lichtempfindlicher Widerstand an der Lichtsensorschnittstelle 5 angeschlossen ist. Andererseits wenn sich der Widerstandswert bei dem Dimmen nicht verändert, schließt das elektronische Vorschaltgerät 2 auf ein zum manuellen Dimmen eingesetzten Potentiometer 11. Je nach Ergebnis dieser automatischen Erkennung wird der Lichtsensor-Modus oder der Potentiometer-Modus aktiviert.The electronic ballast 2 can also detect automatically whether a potentiometer 11 is used for manual dimming or on / off. First, the electronic ballast 2 causes a brightness change or dimming of the connected lamp 3, and at the same time checks whether the resistance value at the sensor interface 5 changes. When this resistance value changes, the electronic ballast 2 concludes that a photosensitive resistor is connected to the light sensor interface 5. On the other hand, if the resistance does not change during dimming, the electronic ballast 2 closes on a potentiometer 11 used for manual dimming after the result of this automatic detection, the light sensor mode or the potentiometer mode is activated.

Gemäß einem Beispiel werden zwei Steuereingänge 6a, 6b bereitgestellt, so dass dem elektronischen Vorschaltgerät 2 externe Steuerinformationen zugeführt werden können. Verschiedene Arten von Steuerinformationen können vom elektronischen Vorschaltgerät 2 über die Steuereingänge 6a, 6b empfangen werden wie u.a. Konfigurationsinformationen, Statusabfrage oder Helligkeitsinformationen.According to one example, two control inputs 6a, 6b are provided so that external control information can be supplied to the electronic ballast 2. Various types of control information may be received by the electronic ballast 2 via the control inputs 6a, 6b, among others. Configuration information, status query or brightness information.

Eine Konfigurationsinformation kann dem elektronischen Vorschaltgerät 2 Auskunft darüber geben, welche Informationen über die Eingänge 4a, 4b bereitgestellt werden. Diese Informationen können insbesondere den aktiven oder den passiven Modus aktivieren, und somit festlegen, ob dem Vorschaltgerät 2 über die Sensorschnittstelle 5 ein Signal eines passiven Bauelements oder ein aktives übermitteltes Signal zugeführt wird.Configuration information can give the electronic ballast 2 information about which information is provided via the inputs 4a, 4b. This information can in particular activate the active or the passive mode, and thus determine whether the ballast 2 is supplied via the sensor interface 5, a signal of a passive device or an active transmitted signal.

Die Konfigurationsinformation kann auch den passiven oder aktiven Modus näher beschreiben bzw. definieren, in dem zum Beispiel festgesetzt werden kann, dass das angeschlossene passive Bauelement ein Lichtsensor zur Lichtregelung, ein Potentiometer zur Lichtsteuerung oder ein Widerstand zur Adressierung des elektronischen Vorschaltgeräts 2 ist. Zum Einsatz eines Widerstandes zum Zweck der Adressierung wird hier ausdrücklich auf die Druckschrift DE 103 29 090 A1 hingewiesen. Der Anschluss von weiteren Bauelementen an die Sensor-Schnittstelle 5 kann über diese Konfigurationsinformation selbstverständlich auch mitgeteilt werden.The configuration information can also describe or define the passive or active mode in more detail, in which it can be stipulated, for example, that the connected passive component is a light sensor for light regulation, a potentiometer for light control or a resistor for addressing the electronic ballast 2. For use of a resistor for the purpose of addressing is expressly to the document DE 103 29 090 A1 pointed. Of course, the connection of further components to the sensor interface 5 can also be communicated via this configuration information.

Die Steuereingänge 6a, 6b können auch als zur Statusabfrage benutzt werden, so dass das elektronische Vorschaltgerät 2 über diese Steuereingänge 6a, 6b beispielsweise mitteilen kann, ob der passive oder der aktive Modus aktiviert ist, oder ob im passiven Modus gerade ein Lichtsensor, ein Potentiometer 11 oder ein Widerstand angeschlossen ist.The control inputs 6a, 6b can also be used as a status query, so that the electronic ballast 2 can communicate via these control inputs 6a, 6b, for example, whether the passive or the active mode is activated, or in passive mode just a light sensor, a potentiometer 11 or a resistor is connected.

Es ist auch möglich, über die Steuereingänge 6a, 6b Helligkeitsinformationen zuzuführen. Somit kann ein paralleler oder zusätzlicher Eingang für die Lichtsteuerung der Lampe 3 geschaffen werden, welcher vorzugsweise die Regelung über Lichtsensor oder die Helligkeitseinstellung über Potentiometer 11 temporär außer Kraft setzt kann. Die Lampe 3 kann dann über die Steuereingänge 6a, 6b auf einfacher Weise ein- und ausgeschaltet werden.It is also possible to supply brightness information via the control inputs 6a, 6b. Thus, a parallel or additional input for the light control of the lamp 3 can be provided, which preferably can temporarily override the regulation via the light sensor or the brightness adjustment via potentiometer 11. The lamp 3 can then be switched on and off via the control inputs 6a, 6b in a simple manner.

Fig. 3 zeigt ein elektronisches Vorschaltgerät 2', das mittels einer Lichtmodulation drahtlos kommunizieren kann. Fig. 3 shows an electronic ballast 2 ', which can communicate wirelessly by means of a light modulation.

Das elektronische Vorschaltgerät 2' enthält eine Modulationseinheit 16, die ein zu übertragenes Signal 19 in entsprechende Steuersignale 20a, 20b für mindestens eine Lampe 3 oder Lampenanordnung moduliert. Die Steuersignale 20a, 20b können insbesondere die Lampe 3 ein- und ausschalten beziehungsweise ihre Helligkeit dimmen. Denkbar sind auch Steuersignale 20a, 20b, die die Frequenz oder die Farbe des von der Lampe 3 oder von der Lampenanordnung emittierten Lichts bestimmen.The electronic ballast 2 'contains a modulation unit 16 which modulates a signal 19 to be transmitted into corresponding control signals 20a, 20b for at least one lamp 3 or lamp arrangement. The control signals 20a, 20b can in particular turn the lamp 3 on and off or dim its brightness. Also conceivable are control signals 20a, 20b which determine the frequency or the color of the light emitted by the lamp 3 or by the lamp arrangement.

Die Modulation der Helligkeit und/oder der Frequenz des emittierten Lichts kann eine bereits bekannte analoge oder digitale Modulation sein.The modulation of the brightness and / or the frequency of the emitted light may be an already known analog or digital modulation.

Vorzugsweise ist diese Lichtmodulation für das menschliche Auge nicht oder kaum zu erkennen. Wird die Helligkeit der Lampe durch Ein- und Ausschalten moduliert, so ist zu beachten, dass das Auge die Beleuchtungsunterbrechung nicht wahrnimmt. Bei einer Signalübertragung durch Modulation der Lichtfrequenz können beispielsweise Frequenzen im nicht sichtbaren Frequenzbereich des Lichtspektrums, d.h. im infraroten und/oder im ultravioletten Bereich, gewählt werden.Preferably, this light modulation is not or hardly recognizable to the human eye. If the brightness of the lamp is modulated by switching it on and off, it should be noted that the eye does not perceive the interruption of the illumination. In a signal transmission by modulation of the light frequency, for example, frequencies in the non-visible frequency range of the light spectrum, i. in the infrared and / or ultraviolet range.

An das elektronische Vorschaltgerät 2' ist auch ein Fotoelement 12 angeschlossen zum Empfang eines modulierten Licht. Diese vom Fotoelement 12 erfasste Information in Form von Helligkeits-Istwerten oder Frequenz-Istwerten wird dem Vorschaltgerät 2' über die Sensorschnittstelle 5 zugeführt. Eine Demodulationseinheit 17 demoduliert anschließend wiederum diese Lichtinformation und entnimmt daraus ein Nutzsignal 18, das dem zuvor gesendeten Signal 19 entspricht.To the electronic ballast 2 'is also a photo element 12 connected to receive a modulated light. This information captured by the photoelement 12 in the form of brightness actual values or actual frequency values is fed to the ballast 2 'via the sensor interface 5. A demodulation unit 17 then again demodulates this light information and extracts therefrom a useful signal 18 which corresponds to the previously transmitted signal 19.

Das in Fig. 3 gezeigte Fotoelement 12 ist ein passiver Empfänger oder ein passives Bauelement in Form beispielsweise eines helligkeitsempfindlichen Lichtsensors oder eines frequenzempfindlichen Sensors wie z.B. IR-Sensor oder UV-Sensor. Bei einem passiven Empfänger ist zu beachten, dass eine maximale Leitungslänge und ein maximaler Abstand zwischen Fotoelement 12 und Vorschaltgerät 2' nicht überschritten werden sollten. Insbesondere sollten diese Leitungslänge und dieser Abstand nicht größer als ein Meter bzw. 50 cm sein. Alternativ zeigt Fig. 4 ein aktives Fotoelement 13, das durch einen Verstärker 14 und einen Optokoppler 15 an die Sensorschnittstelle 5 des elektronischen Vorschaltgeräts 2' angeschlossen ist. Somit kann die Leitungslänge vom Fotoelement 13 über den Verstärker 14 bis zum Optokoppler 15 auch viel größer sein als die maximale Leitungslänge, die das passive Fotoelement 12 der Fig. 3 erfordert. Lediglich die Leitungslänge vom Optokoppler 15 zur Sensorschnittstelle 5 und der Abstand zum Vorschaltgerät 2' sind begrenzt, vorzugsweise auf ein Meter bzw. 50 cm.This in Fig. 3 shown photo element 12 is a passive receiver or a passive device in the form of, for example, a brightness-sensitive light sensor or a frequency-sensitive sensor such as IR sensor or UV sensor. For a passive receiver, it should be noted that a maximum line length and a maximum distance between the photoelement 12 and the ballast 2 'should not be exceeded. In particular, this line length and distance should not be greater than one meter or 50 cm. Alternatively shows Fig. 4 an active photoelement 13 which is connected by an amplifier 14 and an optocoupler 15 to the sensor interface 5 of the electronic ballast 2 '. Thus, the line length of the photoelement 13 via the amplifier 14 to the optocoupler 15 can also be much larger than the maximum line length, the passive photoelement 12 of Fig. 3 requires. Only the line length from the optocoupler 15 to the sensor interface 5 and the distance to the ballast 2 'are limited, preferably to one meter or 50 cm.

Das zu übertragene Signal 19 kann dem elektronischen Vorschaltgerät 2' beispielsweise extern über die Steuereingänge 6a, 6b übermittelt werden. Alternativ kann das Nutzsignal 19 auch von der Sensorschnittstelle 5 gewonnen werden, wobei wiederum ein passives Signal eines passiven Bauelements wie z.B. eines Lichtsensors, oder ein Signal eines aktiven Elements der Sensorschnittstelle 5 zugeführt wird.The signal 19 to be transmitted can be transmitted to the electronic ballast 2 ', for example, externally via the control inputs 6a, 6b. Alternatively, the useful signal 19 can also be obtained from the sensor interface 5, wherein in turn a passive signal of a passive component, such as e.g. a light sensor, or a signal of an active element of the sensor interface 5 is supplied.

Das empfangene Signal 18 kann von der Steuereinheit des Vorschaltgeräts 2' bearbeitet, gespeichert, über die Modulationseinheit und die Lampe 3 weitergesendet, oder sogar über die Steuereingänge 6a, 6b digital weitergeleitet werden.The received signal 18 can be processed by the control unit of the ballast 2 ', stored, transmitted via the modulation unit and the lamp 3, or even forwarded digitally via the control inputs 6a, 6b.

Ein elektronisches Vorschaltgerät 2' ist also dazu geeignet, mittels einer Modulationseinheit 16 und einer Lampe 3 oder Lampenanordnung ein moduliertes Signal zu senden, und mittels eines Fotoelements 12 und einer Demodulationseinheit 17 ein solches moduliertes Signal zu empfangen.An electronic ballast 2 'is thus suitable for transmitting a modulated signal by means of a modulation unit 16 and a lamp 3 or lamp arrangement, and to receive such a modulated signal by means of a photoelement 12 and a demodulation unit 17.

In einem System, das mehrere elektronische Vorschaltgeräte 2' umfasst, ist es notwendig, dass an jedes als Empfänger dienende Vorschaltgerät 2' ein Fotoelement 12 angeschlossen wird. Mehrere Vorschaltgeräte 2' können sich natürlich auch ein Fotoelement 12 teilen, in dem das Ausgangssignal des Fotoelements 12 bis zur Sensorschnittstelle 5 der entsprechenden Vorschaltgeräte 2' weitergeleitet wird. Vorteilhaft ist es in diesem Fall ein aktives Fotoelement 13 anzuschließen, da der Abstand zu den Vorschaltgeräten, wie bereits gesehen, nicht begrenzt ist.In a system comprising a plurality of electronic ballasts 2 ', it is necessary that a photo element 12 is connected to each ballast 2' serving as a receiver. Of course, a plurality of ballasts 2 'can also share a photoelement 12, in which the output signal of the photoelement 12 is forwarded to the sensor interface 5 of the corresponding ballasts 2'. It is advantageous in this case to connect an active photoelement 13, since the distance to the ballasts, as already seen, is not limited.

Ein System zur Beleuchtung eines Raums umfassend mehrere Vorschaltgeräte 2' mit jeweils einer Lampe 3 und einem Fotoelement 12, 13 kann sich diesem Kommunikationsverfahren bedienen, in dem nur ein Vorschaltgerät die Helligkeit des Raums erfasst, und diese Helligkeitsinformation den anderen Vorschaltgeräten per Lichtmodulation übermittelt. Diese anderen Vorschaltgeräte erhalten die Helligkeitsinformation über das jeweilige Fotoelement 12, 13, das als Kommunikations-Empfänger und nicht als Helligkeits-Messgerät dient. Somit kann gewährleistet sein, dass unabhängig von der Kalibrierung der Fotoelemente alle Lampen 3 in einem selben Raum auf die selbe Helligkeit geregelt werden können.A system for illuminating a room comprising a plurality of ballasts 2 ', each with a lamp 3 and a photo element 12, 13 can use this communication method, in which only one ballast detects the brightness of the room, and transmits this brightness information to the other ballasts by light modulation. These other ballasts receive the brightness information on the respective photo element 12, 13, which serves as a communication receiver and not as a brightness meter. Thus, it can be ensured that, regardless of the calibration of the photo elements all lamps 3 can be controlled in the same room to the same brightness.
