<P>PROBLEM TO BE SOLVED: To solve a problem that light volume loss becomes large and a prescribed brightness becomes unabled to be obtained if a half mirror is formed on the surface of an amber ball in order to prevent reflection of the amber ball to a reflection mirror in non-lighting when the amber ball is combined with a transparent outer lens. <P>SOLUTION: Coloring similar to amber color such as yellow is applied to light from a light source 2 with a coloring part C, an amount of light loss in conversion is made to be minimum when the conversion to the amber color is carried out at a color converting part V made as an optical multi-layered film 5, and in order to obtain reflecting light of a metallic color such as silver color, conditions are satisfied that all the wave lengths become necessary to be made contained within the visible range in the reflecting light, thereby the problem is solved. <P>COPYRIGHT: (C)2004,JPO |
