| 主权项 | 1. A headlight for a motor vehicle, in order to provide a cut-off light beam, comprising: a collector mirror with an axis; a source of light (S) placed in the vicinity of the inner focal point of the collector mirror; a substantially flat bender, the reflective surface of which is oriented towards the interior of the collector mirror, and has an edge which is constituted by a flat curve; and a lens, situated to the front of the collector mirror and the bender, in order to provide an image of the edge of the bender which defines the cut-off of the beam; wherein the lens is determined such that, for each section of the lens, along a plane which is at right angles to the edge of the bender, on a point of this edge, the focal point (Fh0) of said section is at a distance (h0) from the point of the edge of the bender, according to a direction at right angles to the plane of the bender. | ||
