ABSTRACT:
A motor vehicle headlamp comprises a light source, a reflector and a cover glass together with at least one dioptre lens adapted to be selectively interposed between the light source and at least one zone of the reflector, so as to modify the resulting light beam by refraction. At least one of the dioptre lenses has a generally cylindrical inner surface, the axis of which lies close to an optical axis of the reflector, the optical axis lying close to the light source, and an outer surface, the inclination of which, with respect to the said inner surface varies progressively in such a way as, firstly, to define by refraction progressive de-focussing of the light source, both horizontally along the optical axis and vertically above and below the optical axis, and secondly, to offset some images of the light source, but essentially in a lateral direction only; and the or each dioptre lens defines an angular extent thereof which is limited so that the lens concerned is interposed between the light source and only one lateral zone of the reflector. The application is applicable generally to the selective homogeneous widening of different types of beams.
