Abstract
A motor vehicle headlamp has a lamp with two filaments, one of which has a masking screen so as to form a chopped or dipped beam, while the other filament is unmasked so as to produce an unchopped beam. The headlight also includes a reflector and a smooth cover lens. The reflector has an upper zone extending between two radial half planes which are inclined by the same amount below the horizontal, this upper zone being larger than the part of the reflector which is exposed to the first filament; the reflector has two lateral sub-zones with base surfaces which are symmetrical with respect to the vertical, with striations being formed by projection on the base surface, the striations being configured according to the particular type of chopped beam required. The reflector also has a second zone having a surface for cooperation with the second filament only, so as to form a wide portion of the beam and extending at least partly above the cut-off of the dipped beam.
