PURPOSE:To diminish a radius of pursuit-rotating body to fix a converging point, and concequently to enhance reliability, by throwing back the sunlight converged by the lens, by reflecting the plane mirror, and by converging the sunlight to the focus where an absorbing body is located. CONSTITUTION:Using a lens pursuit type converger converging the sunlight by lens, the sunlight converged by the lens 1 is reflected by the plane mirror 2 to return in reverse against the incident direction and converged at the focus where the absorbing body 3 is located. The casing 4 consisting of the lens 1 and the plane surface 2 is the pursuit-rotating body as well as useful for the dustproof and the drip-proof device. If the plane mirror 2 is set in the optimum position, the corners a-d of the casing 4 draws the smallest outer peripheral circular arc locus. Further, by pursuit-rotating with the absorbing body 3 as the center, the absorbing body 3 is easily installed and supported in the highly reliable position. |
