Abstract

The invention relates to a discharge lamp whose discharge vessel (1) is pided with a light-transmitting, electrically conductive layer (4) in order to improve the electromagnetic compatibility of the lamp when it is operated from an electronic operating unit. The light-transmitting, electrically conductive layer (4) is advantageously connected to the circuitry-internal ground potential of the operating unit.
