PROBLEM TO BE SOLVED: To prevent false recognition of a signal lamp, reduce the number of parts and attain cost reduction. SOLUTION: A green colored part 6 is subjected which obtains umber colored light L3 by transmitting a colored lens 2 that is light transmissive and pink colored on an inner surface of the colored lens 2. Consequently, strong light L4 such as sun light is colored in umber color when it is passed through the colored lens 2 and the colored part 6 so that umber colored light is reflected to a reflection surface 11 and is irradiated in an umber color to the outside through the colored lens 2 and the colored part 6 again according to reflecting at the reflection surface 11. Accordingly, it is possible to prevent the missing of a functional color and false recognition of a signal lamp since pink colored light is not emitted even though the strong light L4 such as sun light, etc., enters a lighting room at all angles. Moreover, reduction of the number of parts and cost is attained as a color cap is made unnecessary. |
