| 摘要 |
The invention proposes a headlight producing a principal lighting beam with cutoff, comprising a principal light source which is arranged in the vicinity of a first focus of the reflector, a shield which comprises a cutoff edge arranged in the vicinity of a second focus of the reflector, so as to form the cutoff in the principal lighting beam, and a convergent lens, a focal plane of which passes close to the second focus of the reflector, a secondary light source being arranged between the shield and the lens; comprising an optical distribution element arranged in front of the shield, so as to distribute the light rays emitted by the secondary source on the input surface of the principal lens, with a view of producing a secondary lighting beam, the secondary source being arranged outside the path of the light rays coming from the principal source and directed towards the input surface of the principal lens.
