Abstract
A multi-faceted reflector for a headlamp of a motor vehicle is disclosed. The motor vehicle headlamp has the desired optics, in the form of facets, placed entirely on the reflective surfaces of the reflector. The reflective surfaces are comprised of a plurality of discrete reflective surfaces having right (i.e., surfaces of a parabolic shape in the vertical plane and being linear or cylindrical in the horizontal plane) parabolical cylindrical surfaces and discrete simple rotated parabolical surfaces. All of the reflective surfaces are located relative to the light source of the headlamp. The parabolic cylindrical surfaces, serving as spreading facets create a lateral spread of the light developed by the light source of the lamp, whereas, the simple rotated parabolic surfaces, serving as bending facets, create a shifting, relative to the light source, of the projected image of the light source. The shifted light forms the compact high intensity portion of the light output of the headlamp which cooperates with the lateral spread light to form a compact light output which serves the illumination needs of the motor vehicle.
