Abstract

PURPOSE: To eliminate a dark zone and efficiently project parallel rays of light forward and scattered rays of light sideward, by integrating a forward parallel light ray reflector and a sideward scattered light ray reflector with each other on the reflection face of a housing.
CONSTITUTION: The forward parallel light ray reflector 6 shaped as a paraboloid and the sideward scattered light ray reflector 7 shaped as saw teeth are integrated with each other on the reflection face of the housing 1 shaped as a flat plate. A part of light emitted from a bulb 3 is reflected by the reflector 6 so that the parallel rays of light are projected to the central part of a lens 2. Another part of the light emitted from the bulb 3 is reflected by the reflector 7 so that the scattered rays of light are projected to a spherical- prism-shaped peripheral part 21 of the lens 2. Forward parallel light ray reflectors shaped as a paraboloid may be provided alternately with sideward scattered light ray reflectors.
