摘要
A motor vehicle headlight of the elliptical type, giving both a dipped beam and a main beam, has a light source which cooperates with a reflector to produce a patch of light, with a lens projecting the patch of light on the road, and a movable mask being arranged so that, in a working position, it masks a part of the light patch so that the lens produces a cut-off beam, while in an inactive or retracted position of the mask, the lens projects essentially the whole of the light patch so as to produce a beam without any cut-off. The reflector comprises a first zone which produces a first part of the light patch, not significantly masked by the mask in its working position, and a second zone which produces a second part of the light patch. This second part is cut off by the mask in its working position to a much greater extent. The two parts of the light patch have different distributions of the light in a direction transversely to the direction of projection.
