  • Vehicle lighting system
    Patent number: 8277099
    Abstract: A vehicle lighting system according to the present invention is provided, and includes: a pivot portion for optical axis adjustment; an optical axis adjustment mechanism mounting portion for vertical direction; and an optical axis adjustment mounting portion for horizontal direction, which are integrally provided at a heat sink member having a semiconductor-type light source mounted thereon. As a result, the vehicle lighting system becomes capable of efficiently radiating a heat generated in the semiconductor-type light source by means of the pivot portion for optical axis adjustment and the optical axis adjustment mechanism mounting portions for vertical and horizontal directions, which are integrally provided at the heat sink member.

  • VEHICLE LIGHTING DEVICE
    Publication number: 20100321947
    Abstract: A reflector made of a synthetic resin material is positioned and fixed in a heat sink member. At a position spaced from the positioned and fixed portion, a deformation prevention portion for preventing a warping deformation of the reflector is provided for a respective one of the reflector and the heat sink member, thus preventing a warping deformation of the reflector due to a heat generated from a semiconductor-type light source. As a result, the impairment of light distribution performance, caused by a slight warping deformation of the reflector, is avoided. In this manner, a thermal deformation of the reflector due to the heat generated from the semiconductor-type light source is prevented.
