Abstract

Bei der Schaltungsanordnung zum hochfrequenten Betrieb einer Niederdruckentladungslampe (LP) mit einem Netz­ gleichrichter (2) und einem Gegentaktfrequenzgenerator (3) mit einem Serienresonanzkreis und einer Abschalt­ vorrichtung ist die mit dem Plus- oder Minuspol des Netzgleichrichters (2) verbundene Elektrode (E2) zwischen den Netzgleichrichter (2) und den Gegentakt­ frequenzgenerator (3) geschaltet. Durch diese Ver­ schaltung der Elektrode (E2) wird bei Auswechslung der Niederdruckentladungslampe (LP) der Stromkreis unter­ brochen und der Abschaltkreis außer Funktion gesetzt. Bei Einsetzen einer neuen Lampe wird der Stromkreis wieder geschlossen, so daß die Niederdruckentladungs­ lampe (LP) durch den Gegentaktfrequenzgenerator (3) wieder selbsttätig gestartet werden kann. In the circuit arrangement for high-frequency operation a low pressure discharge lamp (LP) with a network rectifier (2) and a push-pull frequency generator (3) with a series resonance circuit and a shutdown device is the one with the positive or negative pole of the Mains rectifier (2) connected electrode (E2) between the mains rectifier (2) and the push-pull frequency generator (3) switched. Through this ver circuit of the electrode (E2) is replaced when the Low pressure discharge lamp (LP) the circuit below broken and the shutdown circuit disabled. When a new lamp is inserted, the circuit is switched off closed again, so that the low pressure discharge lamp (LP) by the push-pull frequency generator (3) can be started again automatically.
