PROBLEM TO BE SOLVED: To make a structure of a fixture main body simple and compact and reduce light loss due to mutual shielding of movable reflecting mirrors or vignetting by changing irradiation direction with the turn of movable reflective mirrors without turning integrally a lamp, a fixed reflective mirror and the movable reflective mirrors. SOLUTION: Movable reflective mirrors 16R, 16L fitted at either side of a fixed reflective mirror 15 are rotatably arranged for free approaching and receding from a lamp 12 with one end side each pivotally supported to the side of the fixed reflective mirror 15 as a fulcrum, and at the same time, the other ends are joined with each other with a link 13 to form a twin-lever mechanism having the movable reflective mirrors 16R, 16L make a back-and-forth angular movement. |
