<P>PROBLEM TO BE SOLVED: To achieve solar light collection in a big capacity with a simple structure and miniaturization of the device as well. <P>SOLUTION: The solar light collecting device 1A is provided with tiltable azimuth mirrors 2 and elevation angle mirrors 3 arranged overlapped in two steps. The azimuth mirrors 2 and the elevation angle mirrors 3 are arranged in plurality and a first rotation axis O1 of the azimuth mirror 2 and a second rotation axis O2 of the elevation angle mirror 3 are arranged in a direction mutually crossing at right angles. While the azimuth mirror 2 is arranged on an incident side of the sunshine, an azimuth mirror angle and an elevation angle mirror angle are computed based on a position of the sun so that the azimuth mirror 2 and the elevation mirror 3 can be respectively controlled in separation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
