Patent ID: 7543969

Claim:
A headlight for a motor vehicle designed to fulfill at least two functions, one of the functions corresponding to a beam with cut-off, comprising: (a) a light source for emitting light rays; (b) a main elliptical reflector having an optical axis, the main reflector comprising an upper portion disposed above the optical axis, a lower portion disposed below the optical axis and a scalloped part disposed in the lower portion; (c) a main lens disposed in front of the main elliptical reflector and having an optical axis essentially parallel to the optical axis of the main reflector; (d) a secondary elliptical reflector coupled to the scalloped part of the main elliptical reflector, the secondary elliptical reflector having an optical axis that is inclined with respect to the optical axis of the main reflector; (e) an additional lens disposed in front of the secondary reflector, the additional lens having an optical axis essentially parallel to that of the main lens; and (f) a retractable shield movable between at least one active position and a retracted position, whereby when the retractable shield is in an active position the headlight produces a cut-off light beam from the light rays emitted by the light source and when the retractable shield is in the retracted position the headlight produces a light beam other than a cut-off light beam from the light rays emitted by the light source.
