HIGH-PRESSURE DISCHARGE LAMP

摘要

The invention relates to a high-pressure discharge lamp comprising a ceramic discharge vessel (3) enclosing a discharge space in which is present an electrode (5) which comprises an electrode beam (20), one end (22) of which is passed through the wall (23) of a cup-shaped lead-through member (24) and is connected thereto in a gas-tight manner. According to the invention, the wall (23) of the lead-through member (24) is caused to deform away from the discharge space around the electrode beam (20) and laterally engages with clamping fit around the electrode beam over a length of at most the diameter of the electrode beam. Thus, a correct positioning of the electrode beam in the lamp is guaranteed and material used for connecting the electrode beam to lead-through member is prevented from entering the discharge space.
