ELECTRICAL INCANDESCENT LAMPS WITH LOW-BEAM (FILAMENT-BLOCKING) SCREENING AND PROCESS FOR THE PRODUCTION OF SUCH LAMPS AS WELL AS LOW-BEAM SCREENING FOR AN ELECTRICAL INCANDESCENTLAMP

摘要

The invention concerns an electrical incandescent lamp with a low-beam cap, particularly 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 a more lower cost lamp manufacture.
