PROBLEM TO BE SOLVED: To improve the degree of design freedom for reducing the vertical width of a cornering lamp and streamlining the design of a vehicle and to improve marketability by preventing the feeling of a lamp during lighting from getting dim like a paper-covered lamp. SOLUTION: For this vehicular signal lamp, because the degree of design freedom is improved by making the color of a lens clear to prevent a meltdown and deterioration due to heat and reducing the vertical width of a cornering lamp, multiple amber LED lamps 4 are used, a main luminous intensity distribution prism part 2 and a diffusion prism part 3 are so installed in the lens as to keep the optical axes after passing the lens in the same direction and to prevent the degradation of appearance, the former comprises even rows and odd rows, the optical axes after passing are each diffused horizontally by providing the optical axis diffusing prism, the problem of a mounting pitch is resolved by tilting all the LED lamps in the same direction and by entering the light without waste by the luminous intensity distribution prism part, and because the LED lamps have conical beam patterns so that there is a part not entering into the main luminous intensity distribution prism part, it is utilized by diffusing it by the diffusion prism part. The vehicular signal lamp looks nice as well. |
