ABSTRACT:
The invention concerns an electrical incandescent lamp with a low-beam cap, articularly a two-filament halogen incandescent lamp and a production process for such a lamp, as well as a low-beam cap. Low-beam screening cap (12) has an opening (14), through which one end (6a) of low-beam filament (6) is threaded. This filament end (6a) is welded to the back side of low-beam screening cap (12) or to a current lead wire (8a), which is attached by a projection welding to the back side of low-beam screening cap (12). The fastening of low-beam filament (6) according to the invention makes possible materials savings in the case of a low-beam screening cap (12) and lower cost lamp manufacture.
