Abstract:
PURPOSE:To precisely and easily position a light source and a light control member relative to each other in such a manner as to obtain a required light distribution characteristic with efficiency by integrating the light source and the light control member together. CONSTITUTION:A halogen lamp 17 has a pair of right and left terminal pins 17a, 17b electrically connected to the pair of right and left electrodes and both provided at the upper end portion of the lamp 17 in such a manner as projecting outward and the lamp 17 is integrated with an almost pyramid-shaped reflector 19 serving as a light control member. The halogen lamp 17 is concentrically inserted into the through hole 20 of the reflector 19 with the pair of terminal pins 17a, 17b upward and is stuck to and integrated with the reflector 19 by an adhesive 21 of cement and the like filling a collar 20a. Since the halogen lamp 17 and the reflector 19 are integrated together, positioning of the halogen lamp 17 and the reflector 19 relative to each other during integration can be correctly and easily carried out with such high precision that a required light distribution characteristic is efficiently obtained.
