(54)	A vehicle headlight comprising a worked reflecting surface for shaping the light beam through reflection

(57) A vehicle headlight of the clear transparent refractor type, comprising a worked reflecting surface for shaping, through reflection only, the light beam from a source lamp (9) wherein the profile of said reflector (19) comprises columnar reflecting surfaces (1) having a cross-section that is an arc of circle and having both curved edges lying on a reference surface of revolution.
Each of said arcs of circle (1) starts and terminates on the profile of the reference parabola (3) at intersection points (5, 7) that are selected so that a light ray from the filament (9) is reflected by said intersection points (3 or 5) into a plane 11 orthogonal to the optical axis 13 at an assigned distance from the center point (15) defined by the intersection of plane 11 with the optical axis 13.
