发明名称 Headlight of the elliptical type for a motor vehicle capable of generating several light beams
摘要 The present invention relates to a headlight for a motor vehicle, comprising a first reflector (20, 20') of elliptical shape, at a first focus (F1) of which is located a main light source (10), the light rays emitted by this source (10) and reflected by the elliptical reflector (20, 2') being directed towards a concentration spot located at a second focus (F2) of the elliptical reflector (20, 2'), the first (F1) and second (F2) focuses of the elliptical reflector (20, 2') defining a main optical axis (Oy) of the elliptical reflector (20, 2'), a convergent lens (30) being placed such that its optical axis is coincident with the main optical axis (Oy) of the elliptical reflector (20, 2') and that the second focus (F2) of the reflector (20, 2') is located on the focal line (LF) of the lens (30) in order to emit a light beam of rays parallel to the main optical axis (Oy). According to the present invention, the headlight comprises at least one optical system concentrating the light rays emitted by a second light source (60) in the direction of a second optical axis (O'y') passing through the optical centre (C) of the lens (30) and over a second concentration spot located on the focal line (LF) of the lens (30), and in that the first (Oy) and second (O'y') optical axes form an angle (alpha) of between 20 et 45° between them.
