ABSTRACT:
A high pressure discharge lamp has a ceramic discharge vessel (8), whose s are closed with plugs (11). The metallic feedthrough, or a main part of it, has a thermal coefficient of expansion which is smaller than the coefficient of the ceramic. The current feedthrough is gas-tightly sintered directly into the plug.
