  • Projector with transverse light source for automotive vehicle
    Patent number: 7125150
    Abstract: Headlight for a motor vehicle comprising a reflector and a light source (S) running transversely to the optical axis (Y—Y) of the reflector and placed near the focal point of the reflector. The transverse light source (S) is placed near the internal focal point (Fi) of an ellipsoidal reflector (R1). The wall of the ellipsoidal reflector has a cutout (1) situated on one side of the plane passing through the geometric axis of the light source (S) and parallel to the optical axis (Y—Y) of the ellipsoidal reflector. A lens (2) with an optical axis parallel to or coincident with that of the ellipsoidal reflector (R1) is placed in front of this reflector, the focal point (3) of the lens being close to the external focal point (Fe) of the ellipsoidal reflector.
