PURPOSE:To efficiently lead solar rays to a prescribed place by combining a lower mobile reflection mirror, which is attached to a building so that it can be moved in accordance with the position of the sun, and an upper fixed reflection mirror fixed to the building. CONSTITUTION:A lower mobile reflection mirror 1 and a holder 2 for the refection mirror 1 hare provided on a building A, and the reflection mirror 1 is rotated around a shaft 3 passing the axis of the reflection mirror 1 on the holder 2 to follow up the direction of the sun. The holder 2 on the building A is supported freely rotatably with a supporting base 4, which is placed on the axis orthogonal to the shaft 3 of the reflection mirror 1, as the fulcrum, and freely expansible and contractible pole braces 5 are interposed between the holder 2 and the building A, and the holder 2 is vertically rotated with the supporting base as the fulcrum together with the reflection mirror 1 by expansion and contraction of pole braces 5 to follow up the altitude of the sun, thus efficiently leading solar rays to a prescribed place. |
