HIGH-PRESSURE DISCHARGE LAMP

摘要

A high-pressure discharge lamp comprising a translucent discharge vessel which encloses a discharge space and has two sealed ends. Two electrodes extend from the sealed ends into the discharge space, and a fill is arranged in the discharge space for generating a gas discharge. Electrical feeds lead out of the sealed ends for supplying energy to the electrodes, with an electrically conductive layer acting as an ignition aid being arranged on the surface of the discharge vessel. The electrically conductive layer comprises at least a first layer section and a second layer section, the first layer section being arranged on a first sealed end of the discharge vessel and extends onto the surface of that region of the discharge vessel which encloses the discharge space. The second layer section is arranged on the second sealed end of the discharge vessel and extends onto the surface of that region of the discharge vessel which encloses the discharge space. The parts of the first and second layer sections which are arranged on the surface of that region of the discharge vessel which encloses the discharge space are arranged at a distance from one another, and the layer sections are DC-isolated.
