Abstract (en)
[origin: EP1100292A1] The circuit has a bias device, an ignition device and a symmetrical lamp filter between the ignition device and a high pressure gas discharge lamp (GDL) enclosed by at least one reflector. The symmetrical lamp filter has a filter capacitance (C1) parallel to the gas discharge lamp and a choke coil (L1,L2) in each of the leads between the parallel circuit and the ignition device. A capacitor (C2,C3) is connected between the lamp reflector and one or each of the lamp supply lines.
