PURPOSE: To light with sunlight to an optional position at an optional time by obtaining the angle of a sunlight reflector on a basis of the position of the sun and a position to be lighted by an operating part of a controller and driving a driving device in accordance with this operation result.
CONSTITUTION: A reflective face which reflects the sunlight L is provided in the front of a sunlight reflector 10, and this reflector 10 is freely rotatable around the horizontal axis and the vertical axis. A controller 16 consists of the operating part and an output part, and the operating part operates the azimuth angle and the altitude angle of the reflector on a basis of the position of the sun S and a prescribed position 18 to be lighted so that the sunlight L is made to light the prescribed position, and the operation result is outputted from the output part to a driving controller 14. The controller 14 receives the output signal from the controller 16 to drive a driving device 12 so that the sunlight is made to light the prescribed position 18, and the angle of the reflector 10 is changed. Thus, the sunlight is made to light an optional position at an optional time in a wide range with one sunlight reflector.
