VARIABLE LIGHT DISTRIBUTION LUMINAIRE

摘要

PROBLEM TO BE SOLVED: To provide a variable light distribution luminaire suppressing light leakage from the vicinity of the adjust operating part, with the light distribution being kept adjustable. SOLUTION: A lamp 1 and a reflector 2 are arranged in a lamp body 10. The reflector 2 comprises a fixed reflector 2a fixed to the lamp body 10 and a movable reflector 2b moving back and forth to the lamp body 10. The movable reflector 2b is coupled with a slider 34 moving back and forth along a guide rod 37. When a knob 30 exposed out of the under surface of the lamp body 10 is rotated to rotate a cam 32, the rotation of the cam 32 is converted to the straight movement of the slider 34. Consequently, an opened portion formed in the lamp body 10 caused by the movement of the movable reflector 2b is small, which suppresses the leakage of the light from this portion.
