Abstract: PROBLEM TO BE SOLVED: To reduce the size and weight of an apparatus by integrally molding a light transmission plate and a frame by providing both with deformation relieving means. SOLUTION: The light transmission plate 2 and the frame 3 are formed by integrating both by means, such as, for example, two-color molding. The coeffts. of linear expansion and water absorptivity of the members constituting the light transmission plate 2 and the members constituting the frame 3 are so set that their respective values are in a range within ±50%, by which the occurrence of the deformation by a difference between dimensional changes is prevented. An acrylic resin is optimum in terms of optical characteristics, such as transparency, as the members which may be adopted for the light transmission plate 2. Then, the dimensional shapes by the ambient temp. and humidity are made exactly the same with both 2, 3 and the occurrence of the deformation is averted if the acrylic resin colored to, for example, white, is adopted for the frame 3 as well. The use of universal resin materials for the frame 3 is made possible as the second deformation relieving means and ABS resins, etc., are adopted.

Abstract: PROBLEM TO BE SOLVED: To provide a lighting tool for a vehicle, which eliminates the need for a component for fixing a heat pipe even in case of using the heat pipe, strong against vibration or shock, and capable of effectively dispersing heat (heat dissipation) during shifting of heat to a heat sink.
SOLUTION: The lighting tool for a vehicle includes an LED light source 11, a reflector 12 equipped with a reflective surface 12a reflecting light from the LED light source 11, and a heat pipe 13 discharging heat from the LED light source 11. The heat pipe 13 is embedded in the reflector 12 (inside a reflector body made of a resin) and fixed to it.
