Abstract

Bei einem Verfahren zur Steuerung der Helligkeit einer Gasentladungslampe (LA), die Bestandteil eines als Last einer Vollbrückenschaltung geschalteten Resonanzkreises (L, C) ist, wird abwechselnd jeweils eine Brückendiagonale eingeschaltet und die andere Brückendiagonale der Vollbrücke ausgeschaltet. In a method for controlling the brightness of a gas discharge lamp (LA), which is part of a connected as load of a full bridge circuit the resonant circuit (L, C) is alternately switched on in each case one bridge diagonal and off the other bridge diagonal of the full bridge. Die Gasentladungslampe (LA) wird während der Einschaltzeit einer Brückendiagonalen in einem ersten Betriebsmodus bei niedriger Lampenhelligkeit mit einer geregelten Gleichspannung und in einem zweiten Betriebsmodus bei hoher Lampenhelligkeit mit einer in ihrem Tastverhältnis veränderbaren Wechselspannung betrieben. The gas discharge lamp (LA) is operated during the on-time of a bridge diagonal in a first operational mode at low lamp brightness at a controlled DC voltage and in a second operational mode at high lamp brightness at a variable in their duty cycle AC voltage.
