Abstract

The invention relates to a high-pressure discharge lamp having a discharge vessel (10) sealed at both ends, a filling which can be ionized and is enclosed in the discharge area (106) of the discharge vessel (10), and electrodes (11, 12) which extend into the discharge area (106), in order to produce a gas discharge, with the discharge vessel (10) having an electrically conductive coating (107) which is designed as a starting aid and is arranged at least in the boundary area (109) between the discharge area (106) and a first sealed end (102) of the discharge vessel (10).
