VEHICLE LIGHTING DEVICE
First Claim
1. A vehicle lighting device, comprising:
- (i) a semiconductor-type light source;
(ii) a reflector having a reflecting surface for reflecting light from the semiconductor-type light source in a predetermined direction;
(iii) a heat sink member in which the semiconductor-type light source and the reflector are positioned and fixed therein, the heat sink member being adapted to radiate a heat from the semiconductor-type light source; and
(iv) a deformation prevention portion which is provided for a respective one of the reflector and the heat sink member at a position spaced from the positioned and fixed site in (iii) and prevents a warping deformation of the reflector due to a heat from the semiconductor-type light source.

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.
