Abstract:
A motor vehicle headlight comprising:a light source;a reflector associated with the light source for reflecting light forward from the source; anda cover lens in front of the reflector and the light source, the reflector being adapted to produce a preformed light beam, the lens being so disposed in relation to the reflector that the lens receives, from at least a substantial part of the reflector, divergent radiation defining a mean angle of incidence in a horizontal plane which varies progressively with horizontal displacement on the lens, wherein the lens defines a zone thereof covered by the divergent radiation, the lens including, at least in the zone covered by the divergent radiation, a set of striations for lateral deflection of the light when the striations are exposed to the divergent radiation, each striation defining an individual angular distribution law determined by the orientation of the light received from the part of the reflector by that striation and by the lateral distribution characteristic of the same striation, the spreading characteristic of the striations being so determined that the aggregate angular distribution law of the striations is essentially uniform.
