  • Sideview mirror assembly with regulating filter using sunlight for automobiles
    Patent number: 4906085
    Abstract: A sideview mirror for automobiles includes a half mirror, a regulating filter mounted in opposed relation to a backside of the half mirror and a light-emitting diode for applying light to the regulating filter. The half mirror has both light reflecting and transmitting characteristics. The regulating filter is so arranged that only part of the light from the light-emitting diode is allowed to pass through the regulating filter to be thereby directed toward a following vehicle and that the remainder of the light from the light-emitting diode is prevented from passing through the regulating filter. Since an image reflected on the half mirror is overlapped with the part of the light from the light-emitting diode, the contrast of the image is reduced.
