Abstract (en)
[origin: ES279982U] A vehicle headlight for providing a shaped beam spreading as a flat bundle. A dish-shaped reflector is employed where the inner reflection surface in the axial longitudinal sections in each case forms an ellipse segment, where the ellipse eccentricity increases from the longitudinal section spanned by the vertical and the reflector axis to the longitudinal section spanned by the horizontal and the reflector axis, where the focal points of the ellipse segments of all sections disposed in planes containing the reflector axis coincide, and where the vertices of the ellipse segments of all sections disposed in planes containing the reflector axis coincide. The depth of the reflector within the longitudinal sections of the reflector containing the reflector axis corresponds to the longer half-axis of the respective ellipse.
