Abstract
A gas discharge lamp having a discharge vessel, for example composed of a base plate, front plate ( ) and frame ( ), has at least one closure element ( ) which closes a discharge vessel opening in a gas-tight fashion by virtue of the fact that the closure element ( ) was inserted into the discharge vessel opening and subsequently fused. The closure element ( ) 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 ( ) and the adjacent wall of the discharge vessel ( ).
