Patent ID: 7134771

Claim:
An automobile lamp assembly comprising: (a) a reflector having an optical axis; (b) a light source placed such that light from the light source impinges upon the reflector and is reflected in a forward direction; (c) a lens located forward of the reflector, such that light reflected by the reflector passes through the lens and exits the lamp assembly in the form of a beam producing an illumination field, the illumination field having an upper area and a foreground area; and (d) a reflective glare reducing shield comprising a ring with a vacant center, teeth arranged about the ring, and a protuberance arranged upon the ring and protruding into the center of the ring, so that the shield is moveable by rotation within a plane generally perpendicular to the optical axis between a first position and a second position, such that when the shield is in the first position, a first illumination level is produced by the beam of light in the foreground area, and such that when the shield is in the second position, a second illumination level is produced by the beam of light in the foreground area, the second illumination level being less than the first illumination level.
