High pressure discharge lamp with an ignition aid

摘要

A high pressure discharge lamp, has an external firing aid strip (4) with enlarged coupling faces (6) in the lamp electrode regions (2). A high pressure discharge lamp has a tubular ceramic discharge vessel (1) with an external electrically conductive firing aid which comprises an axially parallel longitudinal strip (4) of predetermined width (B) and which is provided, in the region of each lamp electrode (2), with a coupling face (6) having a maximum transverse dimension corresponding to an angle of ≤ 180 (especially 50-120) degrees .
