Abstract
A cup-shaped lead-through member is sealed in the wall of a ceramic discharge vessel, and has an electrode beam passing through the end wall of the cup-shaped member and sealed thereto. Immediately adjacent the electrode beam, the cup end wall is deformed away from the discharge space and clamps around the electrode beam over a length of at most the diameter of the beam. A mass of sealing material surrounds the beam end and seals it to the lead-through member, the tight fit of the member end wall to the beam preventing flow of sealing material to the interior of the discharge space.
