<p>PROBLEM TO BE SOLVED: To increase yield without increasing the number of components and suppress the generation of uneven light by arranging a multi-reflector having a cut surface for determining luminous intensity distribution characteristics, and constituting a lens with a clear lens part in the central part and a fisheye cut part in the periphery. SOLUTION: A lens 30 formed by molding acrylic resin consists of a clear lens part 31 in the central part facing a bulb 21 and a fisheye cut part 32 in the periphery. The clear lens part 31 is a connecting body of flat surfaces of transparent resin or curved lines on a plurality of flat surfaces. by the fisheye cut part 32 in which recessed and projecting parts causing irregular reflection are formed on the back surface, although the brightness in the lighting of a bulb 21 is decreased, local darkness is avoided and the generation of uneven light is prevented. By the fisheye cut part 32, since a packing hook is not visible from the outside, a mask for putting it out of sight in made unnecessary. By adjusting the position of an injection gun and concentrating effects causing by injection molding on the fisheye cut part 32, the detects are camouflaged.</p> |
