ABSTRACT:
A circuit arrangement for operating a high-pressure gas discharge lamp has an igniting-circuit circuit arrangement having a capacitor able to be connected via two terminals to a voltage supply unit. The capacitor is connected in parallel with a primary winding of a transformer by a switching element that becomes conductive above a given voltage. The circuit arrangement also has a lamp-circuit circuit arrangement in which the high-pressure gas discharge lamp is connected on one side, via a secondary winding of the transformer, to a terminal for connection to the voltage supply unit. The other side of lamp-circuit is connected, via an inductive element, to a second terminal for connection to the voltage supply unit. The inductive element is formed by an air core inductor or rod core inductor that is exposed or is encapsulated in an insulating substance and that has an inductance equal to or less than 20 μH.
