Abstract

Bei einer Einrichtung zum Zünden und Betreiben elektrischer Gasentladungslampen, insbesondere in Kraftfahrzeugen, mit einer Wechselspannungsquelle (W), an die eine Gasentladungslampe angeschlossen ist, mit einem Übertrager (U), dessen Sekundärwicklung (LS) in Reihe zu der Gasentladungslampe angeordnet ist und die mit einem ersten Kondensator (C1) einen Schwingkreis bildet und dessen Primärwicklung (LP) Teil eines Zündkreises ist, der einen zweiten Kondensator (C2) und einen Halbleiterschalter (H) enthält, mit einer Spannungserkennungseinrichtung (SP) in dem Zündkreis, die über eine Schalteinrichtung mit dem Halbleiterschalter verbunden ist, bilden, um die Blindbelastung für die Wechselspannungsquelle durch den Übertrager zu minimieren und ein sicheres Zünden und Betreiben der Einrichtung zu gewährleisten, die erste Sekundärwicklung des Übertragers, der erste Kondensator und die Gasentladungslampe einen ersten Reihenschwingkreis, wobei die Resonanzfrequenz des ersten Reihenschwingkreises der Grundfrequenz der Spannung der Wechselspannungsquelle entspricht. In a device for igniting and operating electrical gas discharge lamps, in particular in motor vehicles, with an alternating voltage source (W) to which a gas discharge lamp is connected, with a transformer (U), the secondary winding (LS) of which is arranged in series with the gas discharge lamp and which is connected to a first capacitor (C1) forms an oscillating circuit and the primary winding (LP) is part of an ignition circuit, which contains a second capacitor (C2) and a semiconductor switch (H), with a voltage detection device (SP) in the ignition circuit, which is connected via a switching device is connected to the semiconductor switch, in order to minimize the reactive load for the AC voltage source by the transformer and to ensure safe ignition and operation of the device, the first secondary winding of the transformer, the first capacitor and the gas discharge lamp form a first series resonant circuit, the resonance frequency of the first line The resonant circuit corresponds to the fundamental frequency of the voltage of the AC voltage source.
