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.

Figure imgaf001
Circuit arrangement for starting and operating discharge lamps (Lp1, Lp2) with a regulation of the lamp current and a preheating of electrode filaments. For the sequence of preheating, ignition and operating phase no control device is necessary. This is achieved by a preheat resistor, which changes its value after the preheat phase, in combination with regulator properties according to the invention.
