PURPOSE: To guide the sunshine to the shadow part of a building by providing a driving means which varies the direction and altitude angle of a high reflecting mirror automatically with a control signal according to the position shift of the sunshine and a tracking control part.
CONSTITUTION: An arithmetic control part 15 decides on the tracking driving part 1 which reflects the sunshine by the high reflecting mirror 2 according to the azimuth angle of the sun and irradiates a specific place with reflected light, and drives and rotates the reflector 28 of the tracking driving part 1 by servomotors 4 and 8 corresponding to driving parts 3 and 7 so that the azimuth angle and altitude angle of the mirror 2 follow up the sun. Then, the sunshine is reflected by the mirror 2 to a specific place, e.g. the courtyard of a building to irradiate the shadow part. Consequently, each reflector 28 is allowed by the tracking control part 11 and tracking driving part 1 to follow up the sun, thereby irradiating the shadow part with reflected light as far as there is the sunshine.
