PROBLEM TO BE SOLVED: To provide a reflector for a light source lamp efficiently discharging the heat of a lamp and capable of forming a uniform irradiated surface as a reflector for a light source lamp equipped with a receiving recessed part, to which the light source lamp is attached and a reflection surface. SOLUTION: By forming many exhaust through-holes 48a which extend outward in a radial direction from the inside of an area on the reflection surface and providing the change of a tilting angle to the light source lamp 30 between the 1st reflection surface 46 extended from the through-hole 48a to the inside and the 2nd reflection surface 50 extended to the outside, a compensation means radiating shadow formed on an irradiation object surface by the through-hole 48a is obtained. Thus, heat from the light source lamp is efficiently discharged to the outside through the through-hole 48a, and a low illuminance area formed on the irradiation object surface by the through-hole 48a is supplementally irradiated by the compensation means, so that the shadow formed on the irradiation object surface by the through-hole 48a is eliminated, even through the through-hole 48a exists, and overheating of the light source lamp and the reflector is prevented, and further the irradiated surface having uniform illuminance is obtained on the irradiation object surface. |
