  • Publication number: 20160312971
    Abstract: A vehicle lighting fixture can reduce the parts number to reduce the cost as well as achieve weight reduction. The vehicle lighting fixture can include an LED having an optical axis, an ADB reflector configured to hold the LED, and a bracket configured to hold and fix the ADB reflector so that the ADB reflector can rotate around a boss of the bracket parallel to the optical axis of the LED. The ADB reflector can include a hook, and the bracket can have a guiding hole formed therein, so that the hook is engaged with the guiding hole. The ADB reflector can have an elongated screw-insertion hole formed therein, and the bracket can include a screw boss formed therein. The ADB reflector can be fixed to the bracket by screwing, into the screw boss of the bracket, a screw to be inserted to the screw-insertion hole.

  • Patent number: 7244056
    Abstract: A vehicle lamp can include a light source and a reflector whose first focal position lies in the vicinity of the light source, the reflector preferably includes a concave spheroidal surface that reflects light from the light source frontward. A projection lens can be disposed so that its focal point lies in the vicinity of a second focal position of the reflector in front of the light source, the projection lens including an aspherical convex lens that focuses light from the reflector and that irradiates the light frontward. A shutter can be disposed in the vicinity of the second focal position of the reflector, the shutter forming a cutoff for low light distribution. The shutter can be thickly formed so that it is positioned in front of the focal position of the projection lens, and the shutter can be slanted at an end edge that forms the cutoff so that the shutter becomes lower towards the projection lens in relation to the optical axis direction.
