Description

technical field

[0001] The invention relates to a high-pressure discharge lamp as claimed in claim 1 . Background technique

[0002] Such high-pressure discharge lamps, such as those supplied by OSRAM GmbH (Osram GmbH), belong to the lamp family designation and P-VIP as well as halogen-metal-vapor lamps and mercury-ultrahigh-pressure lamps, which are used, for example, in the context of multimedia data projection and video projection. A corresponding lamp design is also described in DE 10 2005 017 505 A1. This known high-pressure discharge lamp has a burner with a discharge vessel on which two diametrically opposite rods are formed. Two electrodes are arranged in the discharge vessel, said electrodes being connected to the supply lines via a sealing foil fused into the rod. In order to improve the ignition characteristics it is possible to provide an auxiliary ignition device which surrounds the part by means of which it is part of a rod wound with an auxiliary ignition ...
