Abstract

A gas discharge lamp having a discharge vessel, for example composed of a base plate, front plate (2) and frame (3), has at least one closure element (6) which closes a discharge vessel opening in a gas-tight fashion by virtue of the fact that the closure element (6) was inserted into the discharge vessel opening and subsequently fused. The closure element (6) consists of a material which is low-melting by comparison with the remainder of the discharge vessel, for example sintered glass. It is possible to dispense with an additional connecting means between the closure element (6) and the adjacent wall of the discharge vessel (2).
