The electric lamp has a lamp vessel ( ) composed of a glass bulb ( ) and a glass plate ( ) sealing the bulb ( ). A shaped metal body ( ) is embedded in the glass plate ( ). The shaped metal body ( ) has a plate-shaped metal member ( ) with which a tube ( ) is integral and with which current conductors ( ) are integral via bridges ( ). The glass plate ( ) has at least one recess ( ) in which a bridge ( ) to a current conductor ( ) is located, which bridge ( ) has a disconnection ( ) in the recess ( ), thus insulating the relevant current conductor ( ) from the metal member ( ). The lamp is of a simple construction that can be easily realized. The current conductors ( ) occupy a predetermined position with respect to one another in the lamp owing to the use of the shaped metal body ( ), and fewer components have to be combined in the manufacture of the lamp.

The electric discharge lamp comprises a shell ( ) having an axis ( ), which shell accommodates a starter ( ) and pin-shaped contacts ( ) extending in an axial direction. A cover ( ), which is coupled to a discharge vessel ( ), is attached to the shell ( ). Pairs ( ) of current conductors ( ) emanate from the discharge vessel ( ). The conductors ( ) of each pair ( ) are clamped, in a direction transverse to the axis ( ), by first and second ( ) forked contact elements, which are secured in the shell ( ) and are directed towards the cover ( ). The lamp is of a simple construction, which can be readily produced.

An electric lamp includes a light-transmitting lamp vessel which is closed in a gastight manner. An electric element is arranged in the lamp vessel and is connected to current conductors which issue from the lamp vessel to the exterior. A lamp cap is connected to the lamp vessel. The lamp cap has a housing which includes a coupler formed as an integral whole with the housing. The coupler and the housing share an integral, resilient intermediate portion.
