<p>The high-pressure discharge lamp has a discharge vessel (1) w ith neck portions (7) of reduced width. The electrode pins (9) have at their free ends an electrode head (10), whose largest diameter is larger than the diameter of the electrode pins (9). Due to the fact that the electrode head (10) must be able to pass through a duct in the neck portion (7) of reduced width when the lamp is assembled, the electrode (2) has lateral play, which may lead to a non-centered position of the electrode (2) in the discharge vessel (1). In the lamp according to the invention, this disadvantage is mitigated in that the electrode pin (9) in the neck portion (7) of reduced width has a transverse dimension which is larger than the diameter of the pin (9), for example due to the presence of a flattened part (11).</p> |
