Automobile rear/stop photo-emissive diode lamp and reflectors, uses segmented auxiliary reflectors each segment comprising a reflecting part and a terraced part

摘要

Width of auxiliary reflectors (24A-24E) and corresponding lenses (32) in direction perpendicular to longitudinal direction of lamp increase by step proportional to length of the auxiliary reflector in projection direction of parallel beams. Their (24A24E) reflecting surface is divided into several segments which extend in the beam projection direction. Each segment includes a reflecting part and a terraced part so that they have a staged configuration. Automobile lamp having several photo-emissive diode light sources (30) and several lenses (32) designed to form parallel beams. The lamp has a reflector (18) which reflects the parallel beams towards the front of the lamp. The reflector is divided into several auxiliary reflectors (24A-24E) arranged parallel to each other and in light incident regions for the beams emanating from the lenses (32). The length of the auxiliary reflectors in the beam direction diminishes by steps from one side of the reflector (18) to the other. The angle of inclination of each of the auxiliary reflectors with respect to the front direction of the lamp increases proportionally to the reduction in length of the auxiliary reflector in the beam projection direction with respect to an adjacent auxiliary reflector. The distance between each of the light sources (30) and the corresponding lens increase by a step proportional to the reduction in length of the corresponding auxiliary reflector in the beam projection direction. A translucid glass (14) is placed in front of the reflector (18).
