摘要

Method for operating a small high-pressure metal-vapour discharge lamp and circuit arrangement for carrying out this method. In order to avoid acoustic resonances in a method for operating a small high-pressure metal-vapour discharge lamp having a periodic operating voltage of constant frequency of greater than 5 KHz, the operating voltage is not only continually abruptly changed in phase but also wobbled in addition. <IMAGE>
