Device for receiving a gas discharge lamp of a vehicle headlight

Abstract

A device for receiving a gas discharge lamp of an automotive headlight has a housing ( ) in which an igniting apparatus is arranged. This housing ( ) also has an insertion opening ( ) with recesses ( ) at an edge in an outer wall ( ) of the housing for receiving a lamp base with radially projecting bayonet lugs ( ) on the base, said lugs axially securing the lamp base ( ) in the insertion opening ( ) when the lamp base is turned into a locked rotational position. A box ( ) is also provided on the housing ( ) for a feeder plug ( ) which provides an electric power supply. With such a device having an integrated igniting apparatus, mechanical locking is provided for the box arranged on the housing to prevent insertion of the feeder plug as long as a bayonet connection of a base of gas discharge lamp is not in the locked rotational position. That is, a latch ( ) in the housing ( ) is arranged such that at least one of the bayonet lugs ( ) of the lamp base ( ) inserted into the insertion opening ( ) can be linked with this latch, and when the lamp base ( ) is turned into the unlocked rotational position, the latch is carried with it into a blocking position in which it projects into the plug area ( ) of the box ( ) on the housing ( ).
