Abstract (en)
[origin: EP0094519A2] 1. Dipped vehicle headlight, with a dished reflector (1) whose internal reflector surface in the axial longitudinal sections forms in each case respective segments of ellipses whereof the vertices (S) and the associated focal points (F) are congruent, and whereof the eccentricity increases from the vertical axial longitudinal section to the horizontal axial longitudinal section, and with an anti-dazzle shield (2) which produces the light-dark boundary and which is situated in the vertical plane of the second focal point (F1) of the ellipse formed in the vertical axial longitudinal section of the reflector, and with a convex condensing lens (3) whose base (4) is rectangular and which is situated at the second focal point (F2) of the ellipse formed in the horizontal axial longitudinal section of the reflector (1), characterised in that the base (4) of the lens is an upended rectangle whose sides are in a ratio of > 1.2:1, and that laterally of the lens (3) there is arranged a prism disc (7, 8) which collects the light (10, 11) in the vertical plane issuing directly from the incandescent lamp and deflects it as a whole downwards, and in the horizontal plane deflects it towards the lens axis (X).
