Abstract
A high-pressure discharge lamp has a pressure chamber with two opposite end regions and delimited by a cylindrical envelope made of glass. An electrode is provided at each of the two end regions, the electrodes projecting into the pressure chamber and being arranged in the pressure chamber as anode and cathode. A discharge chamber is formed between the electrodes. The two end regions of the pressure chamber are designed differently at least outside of the discharge chamber.
