Abstract

Schaltungsanordnung zum Start und Betrieb von Entladungslampen (Lp1, Lp2) mit einer Regelung des Lampenstroms und einer Vorheizung von Elektrodenwendeln. Für die Abfolge von Vorheiz-, Zünd- und Betriebsphase ist keine Steuereinrichtung nötig. Dies wird durch einen Vorheizwiderstand, der seinen Wert nach der Vorheizphase ändert, in Kombination mit erfindungsgemäßen Reglereigenschaften erreicht.
