Abstract

Flackererscheinungen bei Gasentladungslampen sind insbesondere in der Projektionstechnik unerwünscht. Erfindungsgemäß wird das Problem dadurch gelöst, daß ein Lampenbetrieb eingestellt wird, der keinen Brennfleck ausbildet. Zur Realisierung dieses Betriebs wird eine spezielle Regelstruktur vorgeschlagen, die eine Kaskadenstruktur und eine Störgrößenaufschaltung beinhaltet.
