<P>PROBLEM TO BE SOLVED: To solve problems that a conventional snow melting device in a lens of a vehicular lighting fixture has a low thermal efficiency and is unable to melt the snow enough and lacks a practical performance such as securing a range of vision or the like, since heating is carried out from the inside face of a resin lens having a comparatively low thermal conductivity. <P>SOLUTION: In the vehicular lighting fixture, a light transmitting lens 4 is covered from outside of the lens by a heat conductor part 5 formed with a member having a better thermal conductivity than this light transmitting lens and formed in a shape that causes no hindrance to practical use in regard to effect on a light distribution shape and brightness, and by arranging to have these heat conductor part and a heat radiating part 3 connected, the heat of the heat radiating part can be used directly to melt the snow so as to raise the thermal efficiency, enable to melt the snow rapidly, and improve practicality. <P>COPYRIGHT: (C)2009,JPO&INPIT |
