Abstract

Improvements introduced in the manufacture of headlights for vehicle lighting comprising a reflector and two helically wound filaments with extended shafts, the reflector being constructed so that in the working condition of the headlight, the substantially parabolic upper half of this reflector has a spotlight which is located closer to the top of the reflector than the spotlight of the equally substantially parabolic lower half of the reflector, a headlamp in which one of the filaments is provided with its axis concordant with the axis of the reflector between the two spotlights of the reflector, characterized by the fact that the other filament is provided, perpendicular to the axis of the reflector at the focus of the upper half of the reflector or in proximity to it in the working condition of the reflector, while on the focus side of the lower half from the reflector in working condition the headlight, away from the top of the reflector in the upper half the space of the lighthouse is provided with a substantially elliptical hollow mirror that faces the filaments that one of its focuses has in the focus in or near the upper half of the reflector and its other focus in the focus of the lower half of the reflector or in its proximity.
