<P>PROBLEM TO BE SOLVED: To avoid unnecessary cost increase, increase of power consumption, and deterioration of appearance or the like by effectively preventing snow accretion on the outer surface of a hood without attaching a separate snow melting means, and to enhance the degree of freedom in designing the shape of the hood. <P>SOLUTION: The body 3 of a light-emitting part is formed by using one or more power light-emitting diodes 11, and the hood 4 is formed with a thermally conductive material Mm. A heat-transferring support part 12 formed by the thermally conductive material Mm is provided, the body 3 of the light-emitting part is supported by one end side 12f of this heat-transferring support part 12, and the other end side 12r of the heat-transferring support part 12 is connected to the hood 4. Accordingly, heat of the power diodes 11 can be transferred to the hood 4. <P>COPYRIGHT: (C)2009,JPO&INPIT |
