Zusammenfassung:	The proposal is for a circuit arrangement for operating a gas discharge lamp (1) in which the high voltage to strike the gas discharge lamp is generated via the energy stored in a transformer (7) or capacitor. To ensure a steep rise in the ignition voltage, it is fed to the gas discharge lamp via a voltage-controlled switch (5). It is proposed that the voltage-controlled switch (5) takes the form of a tumbler diode which has very short switching times. The ignition circuit is switched off after ignition. This circuit arrangement is especially suitable for striking gas discharge lamps which are still warm from operation. It is therefore particularly suitable for motor vehicle headlamps.
