  • Rear lamp assembly
    Patent number: 8562190
    Abstract: A rear automotive lamp assembly is provided replicating the appearance of a plurality of distinct illumination sources, such as light emitting diodes. The lamp assembly having a light source, at least one reflector, the reflectors having reflective surfaces, the reflective surfaces operable to reflect light from the light source. The reflectors spaced apart and oriented such that light rays from the light source are incident to each of the reflective surfaces are reflected towards a viewing direction. A shield further disposed between the light source and the reflective surface of the reflector. The shield including a plurality of open sections or cutouts thereby allowing a generally collimated light beam from the light source to shine on the reflective surface such that each of the reflective surfaces of the at least one reflector appears as a distinct illumination source from the viewing direction. The openings vary in size and dimension along the length of the shield.
