Abstract

1287869 Vehicle lamps PROJECTEURS CIBIE 2 April 1970 [4 April 1969] 8266/72 Divided out of 1281788 Heading F4R In a vehicle headlamp comprising a parabolic reflector R, or halogen bulb P with a main beam filament Fz and a dipped beam filament Fe associated with a shield C, and a lamp glass G closing the front of the lamp, the lamp glass having in its lower region a series of arcuate ridges (not shown), there is an auxiliary mirror M mounted in front of the lower part of the reflector so as to intercept by its non- reflecting back surface some of the stray light rays originating at the visual image of the dipped beam filament after reflection by the reflector. The mirror M also serves to increase the efficiency of the light flux in the main beam.
