Abstract

A discharge lamp (1) is provided with a discharge vessel (2) comprising a discharge vessel wall made at least partly of a transparent ceramic material, said dis¬ charge vessel wall enclosing a discharge chamber (3) with opposing first (11) and second ends (12), a filling, provided in said discharge chamber (3), a first electrode (7) comprising a first projecting end (8) and a second electrode (5) comprising a second projecting end (6). The first electrode (7) is arranged to project into the chamber (3) from the first end (11) and the second electrode (5) is arranged to project into the chamber (3) from the second end (12). The discharge chamber wall comprises at least one joining seam (4), resulting from a joining of at least two parts (2a, 2b) of ceramic material. The joining seam (4) is located in the discharge chamber wall at a position closer to the first end (11) of the discharge chamber (3) than the first projecting end (8), so that the output beam of the lamp (1) is not impaired by the joining seam (4).
