Definitions

• the invention relates to a headlight lamp according to the preamble of patent claim 1.
• Such a headlight lamp is disclosed, for example, in German published patent application DE 199 51 203 AI.
• This document describes a headlamp lamp with a lamp vessel, an incandescent filament arranged therein, a lamp base in which the lamp vessel is anchored, and two contact tabs which extend in the longitudinal direction of the lamp and which serve to contact the current leads for the incandescent filament projecting from the lamp vessel ,
• the lamp base also has a flange with three resiliently designed tabs, which in turn interact with three reference lugs in order to fix the lamp in a headlight in the manner of a bayonet catch.
• the electrical connection of the headlight lamp to the voltage source takes place independently of the aforementioned bayonet lock with the aid of a plug which is plugged onto the contact lugs after the lamp has been installed in the headlight.
• Figure 1 is a side view of the first embodiment of the headlight lamp according to the invention
• Figure 3 A plan view of the plastic ring with the contact tabs embedded therein
• the preferred exemplary embodiment of the invention shown in FIG. 1 is a two-filament halogen incandescent lamp which is intended for use in a motor vehicle headlight.
• This lamp has a glass, essentially cylindrical lamp vessel 1 with two incandescent filaments 2, 3 enclosed therein, one of which is arranged axially and the other transversely to the longitudinal axis A of the lamp or to the cylinder axis of the lamp vessel 1.
• the axially arranged incandescent filament 2 is partially surrounded by a dimming cap 4 likewise arranged inside the lamp vessel 1.
• the end of the lamp base 9 facing away from the lamp vessel 1 is formed by the plastic handle part 14, which is fixed to the plastic ring 13 and to the base flange 12 by an inseparable plug connection.
• the grip part 14 has a web 14a running perpendicular to the longitudinal axis A, along a diameter of the plastic ring 13. The web 14a can serve as a handle for locking and unlocking the bayonet lock when changing the lamp.
