Headlight for a motor vehicle comprising a reflector and a light source (S) running transversely to the optical axis (Y&#x2014;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 (R). The wall of the ellipsoidal reflector has a cutout () situated on one side of the plane passing through the geometric axis of the light source (S) and parallel to the optical axis (Y&#x2014;Y) of the ellipsoidal reflector. A lens () with an optical axis parallel to or coincident with that of the ellipsoidal reflector (R) is placed in front of this reflector, the focal point () of the lens being close to the external focal point (Fe) of the ellipsoidal reflector. A verticalized reflector (R) is arranged on the opposite side of the cutout () to the most-part of the ellipsoidal reflector (R), this verticalized reflector (R) being designed to produce, from the source (S) housed in the ellipsoidal reflector, a long-range beam which is not intercepted by the lens, the ellipsoidal reflector giving a wide beam of shorter range.

Projector with transverse light source for automotive vehicle

A set of left and right motor vehicle headlamps, each headlamp including a reflector associated with a light source and a closure front-glass. In accordance with the invention, the left and right headlamps are respectively adapted to generate horizontally spread left and right illumination beams, each beam having a fuzzy edge on the left and on the right, said edges being asymmetric relative to the axis of the road, the left edge of the left beam being offset angularly to the left relative to the left edge of the right beam, and the right edge of the right beam being offset angularly to the right relative to the right edge of the left beam. Applications include forming homogeneous beams with a wide spread.

Motor vehicle headlamp having a reflector giving selective light deviation, and methods of making such a reflector

A motor vehicle headlight reflector and a headlight constructed therefrom, wherein the reflector comprises a plurality of laterally juxtaposed zones bounding transition lines with a break of slope. Each zone has a smooth reflective surface and is adapted to spread light horizontally between two limits obtained in the immediate vicinity of the transition lines. The limits of horizontal spread in each zone varies progressively with displacement along the transition line concerned. The invention also includes a method of making the motor vehicle headlight reflector.

Motor vehicle headlight reflector having laterally juxtaposed zones, a

A headlamp for a motor vehicle has a lamp with an axial filament which emits light all around it, together with a reflector and a cover glass. The reflector produces a beam which is delimited by a cut-off line defined by two half planes which are offset from each other in the vertical direction, and which lie on either side of a vertical reference plane. A first lateral zone of the reflector has a reflective surface which forms a concentrated beam delimited by a straight, horizontal first cut-off line, situated entirely on one side of the vertical reference plane. A second zone of the reflector, extending over the base surface of the latter and on the opposite side, has a reflective surface which produces a wide beam delimited by a straight and horizontal second cut-off line. The reflector also includes means for offsetting the light beam vertically, such as to put the first cut-off line at the level of the higher cut-off half plane, and the two zones of the reflector are joined continuously at their intersection along a continuous line extending between the upper and lower edges of the reflector.
