Device for receiving a gas discharge lamp of a vehicle headlight
First Claim
1. A device for receiving a gas discharge lamp of a vehicle headlight, including a housing (1) in which is arranged an igniting apparatus and which has an insertion opening (2) in an outer wall (3) thereof with recesses (4) at an edge of the insertion opening (2) for receiving radially projecting bayonet lugs (18) of a lamp base (17) to be inserted into the insertion opening for securing the lamp base (17) axially when the lamp base is turned into a locked rotational position, said device including a receptacle (9) on the housing (1) for receiving a removable feeder plug (11) in a plug area (10) thereof, which is electrically coupled to an electric power supply for supplying electric power to said device, wherein:
- a latch (13) is arranged in the housing (1) for being linked to at least one of the bayonet lugs (18) of the lamp base (17) when it is inserted into the insertion opening (2) so that when the lamp base is rotated to an unlocked rotational position, said latch is carried with it into a blocking position projecting into the plug area (10) of the receptacle (9) on the housing (1) for preventing said feeder plug from being in said plug area of said receptacle.

Abstract
A device for receiving a gas discharge lamp of an automotive headlight has a housing (1) in which an igniting apparatus is arranged. This housing (1) also has an insertion opening (2) with recesses (4) at an edge in an outer wall (3) of the housing for receiving a lamp base with radially projecting bayonet lugs (18) on the base, said lugs axially securing the lamp base (17) in the insertion opening (2) when the lamp base is turned into a locked rotational position. A box (9) is also provided on the housing (1) for a feeder plug (11) 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 (13) in the housing (1) is arranged such that at least one of the bayonet lugs (18) of the lamp base (17) inserted into the insertion opening (2) can be linked with this latch, and when the lamp base (17) 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 (10) of the box (9) on the housing (1).
