Abstract (en)
[origin: EP1152645A1] The method involves continuously or discontinuously measuring the value of at least one operating parameter of the gas discharge lamp that varies over time and selecting the frequency of the alternating voltage or current (the operating frequency) depending on the measured value, e.g. of the total operating duration, the burn voltage, the emitted or tapped power, the arc length and the electrode separation. Independent claims are also included for the following: an arrangement for operating a gas discharge lamp, a gas discharge lamp with two electrodes, a projector with a gas discharge lamp, a vehicle with a gas discharge lamp, a projector with a device for operating a gas discharge lamp, a vehicle with a device for operating a gas discharge lamp, a method of machining an electrode and a machine-readable data medium with a control program for controlling a device for operating a gas discharge lamp.
