METHOD AND CIRCUIT FOR OPERATING DISCHARGE LAMP

METHOD AND CIRCUIT FOR OPERATING DISCHARGE LAMP

In the case of a method for operating a high-pressure metal-vapour discharge lamp having a cyclic (periodic) operating voltage at a constant frequency of more than 500 Hz, the phase of the operating voltage is continuously changed, suddenly, in order to avoid acoustic resonances.
