发明名称 Vehicle lamp having a reflective containing film coating aluminum flakes
摘要 A vehicle lamp is fitted with a reflective coated reflector which is capable of obtaining a greater center luminous intensity than conventional reflective coated reflectors. The vehicle lamp includes a light source, a reflector for reflecting light from the light source, and a front lens disposed in front of the light source. The reflective surface of the reflector is formed with a luminance reflective coating film containing aluminum flakes that are arranged so as to have a center luminous intensity of 8,000 cd or greater. An aluminum flake layer with the aluminum flakes piled up therein is formed in the surface layer portion of the luminance reflective coating film, and the aluminum flake layer forms a reflective surface for reflecting light. The aluminum flakes mixed in the luminance reflective coating film are thinner (0.01-0.06 mum thick) than the aluminum flakes (0.1 mum or greater in thickness) mixed in a conventional reflective coating film. The aluminum flake layer is uniformly extended along the surface of the reflective coating film and the surface of the luminous intensity layer is smooth, so that the specular reflectance provides for a center luminous intensity of 8,000-13,000 cd.
