Abstract
A motor vehicle headlamp has a cover glass closing a reflector that contains a light source. The reflector comprises upper and lower portions joined through a reflective base. Its lower portion is reflective and/or diffusive, while its upper portion has reflective means which at least partly retransmit light from the source in a beam passing through the cover glass. The reflecting means comprise cylindro-elliptical or ellipsoidal Fresnel ribs which concentrate the reflected beam in a focal zone in front of the cover glass. The beam diverges beyond this focal zone.
