Projector with transverse light source for automotive vehicle

A headlight for a motor vehicle comprising:

• a reflector and a light source running transversely to an optical axis of the reflector, wherein:
• the reflector is an ellipsoidal reflector and the transverse light source is placed near an internal focal point of the ellipsoidal reflector;
• a wall of the ellipsoidal reflector has a cutout situated on one side of a plane passing through a geometric axis of the light source and parallel to the optical axis of the ellipsoidal reflector,
• a lens with an optical axis parallel to or coincident with that of the ellipsoidal reflector is placed in front of the reflector, a focal point of the lens being close to an external focal point of the ellipsoidal reflector,
• and a verticalized reflector is arranged on a side of the cutout opposite to the most-part of the ellipsoidal reflector, this verticalized reflector being designed to produce, from the light source 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, said verticalized reflector having striations delimiting at least one central facet and two lateral facets that are inclined toward one another, wherein the verticalized reflector is separated from said ellipsoidal reflector by a gap.
