Abstract (en)
[origin: EP0373065A1] The invention relates to a motor vehicle headlight, of the type comprising a filament lamp (100), a reflector (200) defining an optical axis and a sealing lens, the filament emitting freely all around it in a radial direction and the reflector exhibiting a substantially continuous and smooth reflecting surface which reflects the rays emitted by the filament in such a manner that they are for the most part situated below a cut constituted by two half planes of given heights and inclinations. According to the invention, the reflecting surface comprises a central zone (201i-206i) which reflects the rays emanating from the filament in order that they should propagate in planes which are substantially vertical and parallel to the optical axis, two intermediary zones (201m, 203m, 205m; 202m, 204m, 206m) situated on either side of the central zone and connected thereto with continuity, which reflect the rays emanating from the filament while imparting to them a substantial deflection in planes which are substantially parallel to the cut off half plane, in the definition of which the ray participates, and at least one marginal zone (201e, 203e, 205e; 202e, 204e, 206e) situated outside one of the intermediary zones and connected thereto with continuity, which reflects the rays emanating from the filament in order that they should propagate in planes which are substantially vertical and parallel to the optical axis.
