The headlight has a reflector (2) with a refractor (6) placed in a pupillary plane of the reflector, where the refractor is a relevant portion of a convex lens (4). The lens having an optical axis comprises a focus (F) merged with another focus of the reflector. A contour (7) of the lens has a baric center (B) shifted to a preset distance with respect to an optical center (O) of the lens. Luminous rays (R2, R3`) crossing the portion are equal to a predetermined fraction of luminous rays (R1, R2, R3, R3`), where the rays come from a light source (S). |
