Abstract

Die Erfindung betrifft ein Betriebsgerät zum Betrieb von Hochdruck-Gasentladungslampen. Insbesondere handelt es sich um ein Betriebsgerät mit einer Steuerung des Anlaufs von Hochdruck-Gasentladungslampen, die eine im Vergleich zum Stand der Technik verkürzte Anlaufphase bewerkstelligt. Dies wird erreicht durch einen Lampenzustands-Detektor, der nach der Zündung erkennt, dass eine heiße Lampe vorliegt und daraufhin den Anlaufstrom erhöht.

The invention relates to an operating device for operating high-pressure gas discharge lamps. In particular, it is an operating device with a control of the start-up of high-pressure gas discharge lamps, which accomplishes a shortened compared to the prior art start-up phase. This is achieved by a lamp condition detector, which detects after ignition that a hot lamp is present and then increases the starting current.
