PURPOSE: To easily adjust the angle, position, and area of illumination light by installing a first mirror which radiates the light of a light source in the direction different from the direction of a body to be illuminated and a second mirror which changes the light in the radiating direction to the direction of the body to be illuminated, then radiates it, and using the first mirror and/or the second mirror as the mirror for reflecting the light other than heat rays of the light source. CONSTITUTION: A first mirror 2 which is a dichroic parabolic mirror having a light source lamp 1 in the center and a second mirror 4 which reflects the light on the optical axis of the lamp 1 and uses it as the radiating light 3 in a body to be illuminated direction are housed in a case 5. The mirror 4 is also a dichroic mirror and supported with a shaft 8 installed in the case 5, pivoted on a shaft 8 so that the both surfaces reflects light in the radiating light 3 direction to the optical axis of the lamp 1, and locked every 180 degrees. The case 5 is rotatably supported in the arm 17 of a stand 16 with a shaft 18 and can be slanted, the arm 17 is supported so as to be capable of horizontally rotating in the shaft 19 of stand 16, and the radiating light 3 can freely change the vertical position, the angle in the vertical direction, diffusion degree, and radiating range. |
