Abstract (en)
[origin: WO2006108406A1] The invention relates to a device for operating or starting a high-pressure discharge lamp (10), whereby the device comprises a voltage-dependent switch (131), for generation of the starting voltage for the high-pressure discharge lamp (10), the switch threshold voltage of which is greater or equal to the starting voltage of the high-pressure discharge lamp (10) and a corresponding operating or starting method. The invention permits an impulse starting of the high-pressure discharge lamp (10) without use of a starter transformer. Said impulse starting device and said method may be advantageously combined with the high-frequency operation of the high-pressure discharge lamp (10), in particular, with a vehicle headlight high-pressure discharge lamp.
