Reflector for motor vehicle rear lamp - has two partial reflectors with number of partial reflector surfaces, alternately radially aligned with common reflector axis

摘要

The reflector safeguards different reflection effects, while being of simple design and small dimensions and while the illumination of the dispersion disc remains uniform. The reflector surface is formed by two parabolic partial reflectors, forming an integral unit. Each partial reflector has a different focal length, and their focal points do not coincide. The two partial reflectors each consist of a number of partial reflector surfaces. The partial surfaces are alternately radially arranged to a common reflector axis. The outer surfaces are formed by uniformly distributed radial strips with grooves in between, whose side surfaces lie in common axial planes. Pref. fifty reflector, partial surfaces are distributed over an angular range of 280 degrees about the reflector axis. Both partial reflectors may penetrate each other in a half of the reflector axial length, related to the common reflector axis.
