- the dimmable electronic ballast can be replaced by a static device to use the LED driver circuit instead of the dimmable circuit.
- the LED driver circuit can of course also be used with dimmable electronic ballasts. For low levels of brightness, the LED driving circuit is more energy efficient to operate than the lamp-only circuit, which provides the necessary and no contribution to the generation of light preheat energy.
- the arrangement of the LED driver circuit is preferably carried out with the circuit in a common housing, so that in particular known conventional housing can be reused and the possibility of retrofitting conventional Luminaires with LEDs is given.

- this is a lamp with a single lamp and a single LED, which are operated together by an electronic ballast.
- the LED can in this case be integrated together with the lamp, for example, in a single housing or in a building ceiling.
- the system efficiency (lumens / watt) is better for a desired minimum illumination due to the LED used than for a gas discharge lamp, in dimmed operation.

- an emergency light circuit may be designed such that it activates the light-emitting diode in the emergency light case instead of the lamp, so that a sufficient illumination for this case is achieved with simultaneous minimum energy use.
- Eventually provided emergency power storage which provide sufficient energy regardless of an external energy source in the emergency light activation case, reach longer Uptime. Therefore, a circuit of the electronic ballast which can charge the emergency power storage is also particularly advantageous.

- a design including a housing 1 in this embodiment includes a series of supply terminals for an LED driver circuit 2 and a fluorescent lamp circuit 3.
- a connection 4 as a switched-supply connection for the circuit and a connection 5 as an unswitched-supply connection for the LED driver circuit enable independent operation of the circuits 2 and 3 and thus independent operation of LEDs 6 to be attached to light emitting diodes or a at the four poles of a terminal 7 mounted fluorescent lamp. Instead of using four poles (with cathode preheating), only two poles can be provided for operating a gas discharge lamp.
- the terminals 4 and 5 share in this case a neutral terminal 20.

- Port 10 again comprises a switchedsupply while port 9 comprises an unswitched-supply .
- Fig. 3 is located in a housing 1 electronic ballast via a terminal 11 equipped with a battery charging system, which in addition to a power failure detection 12 has a circuit 13 for charging an emergency power storage.
- This circuit 13 includes an EMC filter and is used to charge a battery.
- the power failure detection 12 and the charging circuit 13 form an emergency light circuit. If a power failure is detected, the LED driver circuit is powered by means of the terminal 11 previously charged and not shown accumulator.
- Such LED emergency lighting operation is as described energetically cheaper as a dimmed bulb operation, since no cathode heating is needed.
- An inventive lighting system can thus make appropriate illumination of, for example, escape routes, emergency exits or collection points with appropriate directional characteristics of the associated LEDs.
- at least one gas discharge lamp is to be operated via the connection 7.
- the separate switching on and off of the LED operating part is made possible in particular for general lighting purposes.

- a high-current LED 16 is arranged in a reflector 15 between two fluorescent lamps 14.
- the LED 16 is located at a central point of the system.
- the focus of the LED is thus, for example, in the center of the otherwise illuminated by the lamps 14 area, which is sufficient in an emergency light case.
- Conventional reflectors 15 as well as conventional lamps can be used, wherein an electronic ballast according to the invention operates both bulbs 14 and 16 but does not require more space than previously required if the electronic ballast has identical dimensions or at least identical attachment points for mounting in such a bulb system.
- the embodiment according to the Fig. 7 shows a high-current LED 16 at a central location of the lighting system, which in this simple case shown consists of a circular fluorescent lamp 14 and only one LED 16.
- the illuminant system can enable a variable arrangement of the LEDs via, for example, displaceable plug-in contacts. Not only a central arrangement can improve illumination of certain areas.
- Fig. 8 to 10 further embodiments of a lighting system according to the invention can be seen, in each case different fluorescent lamps 14 and a different number of high-current LEDs 16 are used.

Des Weiteren betrifft die vorliegende Erfindung ein Leuchtmittelsystem mit wenigstens einer vorzugsweise als Gasentladungslampe ausgebildeten Lampe und zumindest einer Leuchtdiode.The present invention relates to an electronic ballast for operating at least one lamp, in particular a gas discharge lamp, with a circuit preferably designed as a bridge circuit, via which at least one provided for connection to the lamp terminal with a supply voltage can be acted upon. Furthermore, the present invention relates to a lighting system with at least one preferably designed as a gas discharge lamp lamp and at least one light emitting diode.
Dimmbare Lampen, insbesondere Gasentladungslampen, müssen für einen Betrieb im dimmbaren Bereich einen großen Teil der Eingangsleistung für die Vorheizung von Lampenwendeln aufwenden. Wenn beispielsweise in öffentlichen Gebäuden nur minimale Anforderungen an eine Mindestbeleuchtung eines unbenutzten Raumes gestellt werden ergibt sich durch die notwendige Vorheizung ein vergleichsweiser hoher Energieverlust. Es ist Aufgabe der vorliegenden Erfindung, den Energieverlust von derartigen Leuchtmittelsystemen zu reduzieren.Dimmable lamps, in particular gas discharge lamps, have to spend a large part of the input power for the preheating of lamp filaments for operation in the dimmable range. If, for example, only minimal requirements are placed on a minimum illumination of an unused room in public buildings, the necessary preheating results in a comparatively high energy loss.

Die Aufgabe wird gelöst durch einen Gegenstand nach dem Oberbegriff des Anspruchs 1, welcher sich durch die kennzeichnenden Merkmale des Anspruchs auszeichnet. Des Weiteren wird die Aufgabe gelöst durch einen Gegenstand gemäß Anspruch 7.The object is achieved by an article according to the preamble of
Ein gattungsgemäßes elektronisches Vorschaltgerät zeichnet sich erfindungsgemäß durch eine LED-Treiberschaltung zum Betrieb zumindest einer Leuchtdiode für Beleuchtungszwecke aus, wobei die LED-Treiberschaltung mit dem Schaltkreis gemeinsam in einer Bauform angeordnet ist. Die gemeinsame Bauform ermöglicht die kompakte Anordnung von Schaltkreis und LED-Treiberschaltung aneinander zur Erzielung schaltungstechnischer Vorteile in Form von beispielsweise Platz- und oder Bauteilersparnissen. Die gemeinsame Bauform kann durch eine beispielsweise durch Verlöten realisierte direkte Verbindung von Platinen des Schaltkreises und der LED-Treiberschaltung realisiert werden. Ein solches elektronisches Vorschaltgerät schafft die Voraussetzungen für die Verwendung einer einzelnen oder mehrerer Leuchtdioden anstelle eines Betriebs einer Gasentladungslampe vorzugsweise im abgedimmten Bereich, wobei insbesondere durch die gemeinsame Bauform eine kompakte Anordnung erreicht wird. Darüber hinaus kann eine gemeinsame Bauform beispielsweise auch durch eine den Schaltkreis und die LED-Treiberschaltung umfassende Vergussmasse oder Gehäusewandungen eines zugehörigen Leuchtengehäuses gebildet werden, was in einer kompakten Handhabung des erfindungsgemäßen elektronischen Vorschaltgeräts mündet.A generic electronic ballast is characterized according to the invention by an LED driver circuit for operating at least one light emitting diode for illumination purposes from, wherein the LED driver circuit is arranged with the circuit together in a design. The common design allows the compact arrangement of circuit and LED driver circuit to each other to achieve circuit advantages in the form of, for example, space and or component savings. The common design can be realized by a realized for example by soldering direct connection of circuit boards of the circuit and the LED driver circuit. Such an electronic ballast provides the conditions for the use of a single or multiple light-emitting diodes instead of operating a gas discharge lamp, preferably in the dimmed region, wherein in particular by the common design, a compact arrangement is achieved. In addition, a common design, for example, by a circuit comprising the circuit and the LED driver circuit potting compound or housing walls of an associated lamp housing are formed, resulting in a compact handling of the electronic ballast according to the invention.
Das dimmbare elektronische Vorschaltgerät kann bei Bedarf durch ein statisches Gerät ersetzt werden, um statt des Schaltkreises im dimmbaren Bereich die LED-Treiberschaltung zu verwenden. Die LED-Treiberschaltung kann natürlich auch bei dimmbaren elektronischen Vorschaltgeräten verwendet werden. Für geringe Helligkeiten ist die LED-Treiberschaltung energieeffizienter betreibbar als der nur für die Lampe ausgebildete Schaltkreis, über den die benötigte und keinen Beitrag zur Lichterzeugung leistende Vorheizenergie bereitzustellen ist.If necessary, the dimmable electronic ballast can be replaced by a static device to use the LED driver circuit instead of the dimmable circuit. The LED driver circuit can of course also be used with dimmable electronic ballasts. For low levels of brightness, the LED driving circuit is more energy efficient to operate than the lamp-only circuit, which provides the necessary and no contribution to the generation of light preheat energy.
Die Anordnung der LED-Treiberschaltung erfolgt mit dem Schaltkreis vorzugsweise in einem gemeinsamen Gehäuse, so dass insbesondere bekannte herkömmliche Gehäuse weiterverwendbar sind und die Möglichkeit zur Nachrüstung herkömmlicher Leuchten mit LEDs gegeben ist. Im Nachfolgenden wird davon ausgegangen, dass Schaltkreis und LED-Treiberschaltung insbesondere in einem gemeinsamen Gehäuse angeordnet sind, wobei dieses insbesondere Anschlüsse für wenigstens eine Lampe und eine LED aufweisen kann.The arrangement of the LED driver circuit is preferably carried out with the circuit in a common housing, so that in particular known conventional housing can be reused and the possibility of retrofitting conventional Luminaires with LEDs is given. In the following, it is assumed that the circuit and the LED driver circuit are arranged in particular in a common housing, which may in particular have connections for at least one lamp and one LED.
Die Aufgabe wird ebenfalls gelöst durch ein Leuchtmittelsystem mit wenigstens einer vorzugsweise als Gasentladungslampe ausgebildeten Lampe und zumindest einer Leuchtdiode, wobei das Leuchtmittelsystem ein elektronisches Vorschaltgerät umfasst, welches sowohl zum Betrieb der Lampe als auch der LED vorgesehen ist. In einem einfachen Fall handelt es sich hierbei um eine Leuchte mit einer einzigen Lampe und einer einzigen LED, welche gemeinsam von einem elektronischen Vorschaltgerät betrieben werden. Die LED kann hierbei zusammen mit der Lampe beispielsweise in einem einzigen Gehäuse oder auch in eine Gebäudedecke, integriert sein. Im erfindungsgemäßen Leuchtmittelsystem aus Schaltkreis, LED-Treiberschaltung, Lampe und LED ist die Systemeffizienz (Lumen/Watt) bei einer gewünschten Minimalbeleuchtung aufgrund der verwendeten LED besser als bei einer Gasentladungslampe, im gedimmten Betrieb.The object is also achieved by a lighting system with at least one preferably designed as a gas discharge lamp lamp and at least one light emitting diode, wherein the lighting system comprises an electronic ballast, which is provided for both the operation of the lamp and the LED. In a simple case, this is a lamp with a single lamp and a single LED, which are operated together by an electronic ballast. The LED can in this case be integrated together with the lamp, for example, in a single housing or in a building ceiling. In the lighting system of circuit, LED driver circuit, lamp and LED according to the invention, the system efficiency (lumens / watt) is better for a desired minimum illumination due to the LED used than for a gas discharge lamp, in dimmed operation.
Die LED-Treiberschaltung und der Schaltkreis des EVG bzw. des Leuchtmittelsystems, welcher vorzugsweise als Brückenschaltung ausgebildet ist, können über zugehörige Eingänge separat schaltbar sein, um die Schaltungen des Geräts möglichst getrennt zu gestalten. Es kann jedoch ebenfalls vorteilhaft sein, die beiden Schaltungen über einen gemeinsamen Eingang, beispielsweise abhängig in Höhe der Eingangsspannung, zu schalten.The LED driver circuit and the circuit of the electronic ballast or of the lighting system, which is preferably designed as a bridge circuit, can be switched separately via associated inputs in order to make the circuits of the device as separate as possible. However, it may also be advantageous to switch the two circuits via a common input, for example, depending on the input voltage.
Ein Gehäuse eines elektronischen Vorschaltgeräts weist hierbei vorzugsweise zumindest einen, besser zwei Anschlüsse für eine Leuchtdiode auf, die über die LED-Treiberschaltung versorgt werden. Bei letzterer handelt es sich beispielsweise um eine Sperrwandlerschaltung, wie sie im Stand der Technik (beispielsweise aus der
Solche Sperrwandlerschaltungen wie auch andere LED-Treiberschaltungen können insbesondere bei einer erfindungsgemäßen Weiterbildung eines elektronischen Vorschaltgeräts zusammen mit dem Schaltkreis auf einer Platine angeordnet werden, wodurch in dem Gehäuse des elektronischen Vorschaltgeräts weitere Platzeinsparungen erreicht werden und die Bestückung während des Herstellungsprozesses vereinfacht ist.Such flyback converter circuits as well as other LED driver circuits can be arranged together with the circuit on a circuit board, in particular in a development of an electronic ballast according to the invention, whereby further space savings are achieved in the housing of the electronic ballast and the assembly is simplified during the manufacturing process.
Besondere Vorteile ergeben sich hinsichtlich der Ökonomie des elektronischen Vorschaltgeräts, wenn der Schaltkreis und die LED-Treiberschaltung eine gemeinsame Schaltung aufweisen, d.h. die LED-Treiberschaltung in den Schaltkreis integriert ist und/oder wenn die beiden Schaltungen einen gemeinsamen Funkschutzfilter aufweisen. Die beiden getrennten Schaltungen werden durch die Verwendung entsprechend ausgelegter Bauteile günstiger.Particular advantages arise with regard to the economics of the electronic ballast when the circuit and the LED driving circuit have a common circuit, i. the LED driver circuit is integrated in the circuit and / or if the two circuits have a common radio-protection filter. The two separate circuits are cheaper by the use of appropriately designed components.
Vorteilhafterweise umfasst das elektronische Vorschaltgerät auch eine Notlichtschaltung, die entweder über einen eigenen Eingang spannungsversorgt und/oder aktiviert werden kann oder auch über eine der weiteren Komponenten des elektronischen Vorschaltgeräts aktiviert werden kann. Eine solche Notlichtschaltung kann dergestalt ausgebildet sein, dass sie im Notlichtfall anstelle der Lampe die Leuchtdiode aktiviert, so dass eine für diesen Fall ausreichende Beleuchtung unter gleichzeitiger minimaler Energieverwendung erreicht wird. Etwaig vorzusehene Notstromenergiespeicher, die unabhängig von einer externen Energiequelle im Notlicht-Aktivierungsfall ausreichend Energie zur Verfügung stellen, erreichen so längere Betriebszeiten. Besonders vorteilhaft ist daher ebenfalls eine Schaltung des elektronischen Vorschaltgeräts, die den Notstromenergiespeicher laden kann. Eine Notbeleuchtungsphase, die durch eine Notlichtschaltung aktiviert wird oder durch eine solche gekennzeichnet ist, kann beispielsweise bei einem Fehlerfall in der Lampe oder einer Schaltung des EVG oder durch ein externes (Not)Signal ausgelöst werden.Advantageously, the electronic ballast also includes an emergency light circuit, which can either be powered by a separate input and / or activated or can be activated via one of the other components of the electronic ballast. Such an emergency light circuit may be designed such that it activates the light-emitting diode in the emergency light case instead of the lamp, so that a sufficient illumination for this case is achieved with simultaneous minimum energy use. Eventually provided emergency power storage, which provide sufficient energy regardless of an external energy source in the emergency light activation case, reach longer Uptime. Therefore, a circuit of the electronic ballast which can charge the emergency power storage is also particularly advantageous. An emergency lighting phase, which is activated by an emergency light circuit or is characterized by such, can be triggered, for example, in the event of a fault in the lamp or a circuit of the electronic ballast or by an external (emergency) signal.
Mit dem erfindungsgemäßen elektronischen Vorschaltgerät ist es möglich, ein eigentlich für den statischen Betrieb einer Leuchtstofflampe vorgesehenes elektronisches Vorschaltgerät dergestalt weiterzubilden, dass auch in Gebäuden, in denen nur dimmbare Vorschaltgeräte vorgesehen sind, ein statisches elektronisches Vorschaltgerät verwendet werden kann. Die Kombination von statischen Vorschaltgerät und der LED-Treiberschaltung in einem Gerät ermöglicht es, anstelle einer Leuchtstofflampe eine Leuchtdiode zu aktivieren.With the electronic ballast according to the invention, it is possible to further develop an electronic ballast actually provided for the static operation of a fluorescent lamp in such a way that even in buildings in which only dimmable ballasts are provided, a static electronic ballast can be used. The combination of static ballast and the LED driver circuit in one device makes it possible to activate a light-emitting diode instead of a fluorescent lamp.
Erfindungsgemäß ist es in einer weiteren vorteilhaften Ausbildung vorgesehen, das Leuchtmittelsystem mit einer Mehrzahl von Leuchtdioden zu versehen, wobei eine Änderung der vom Leuchtmittelsystem abgegebenen Lichtleistung durch Schalten einer Anzahl dieser Leuchtdioden ermöglicht ist. Diese Dimmung durch stufenweises Schalten von Leuchtdioden in Kombination mit einer Leuchtstofflampe ermöglicht bei einer gewählten Anzahl von Leuchtdioden eine flexible Gestaltung einer bestimmten Lichtleistung.According to the invention, it is provided in a further advantageous embodiment to provide the lighting system with a plurality of light emitting diodes, wherein a change in the light output by the light source system by switching a number of these light emitting diodes is possible. This dimming by stepwise switching of light emitting diodes in combination with a fluorescent lamp allows for a selected number of light emitting diodes flexible design of a specific light output.
Besonders vorteilhaft ist weiterhin eine Ausbildung eines Leuchtmittelsystems mit einem Bewegungsmelder, der über eine Verbindung mit dem elektronischen Vorschaltgerät dergestalt geschaltet ist, dass bei einem Auslösesignal des Bewegungsmelders die Lampe eingeschaltet wird und die Leuchtdioden entweder abgeschaltet oder zusätzlich geschaltet werden bzw. bleiben.Particularly advantageous is furthermore a design of a lighting system with a motion detector, which is connected via a connection with the electronic ballast such that when a trigger signal of the motion detector, the lamp is turned on and the LEDs are either switched off or additionally switched or remain.
