Abstract
The present invention provides an optical solar collector, in which a spherical or aspheric reflector coated with specular coating is set upon the optical circuit; on the other hand, an optical concentrator is built upon the front of the spherical or aspheric reflector oppositely and directly. Due to applying above-mentioned structure, like building up spherical or aspheric reflector on the optical circuit cooperating to an optical concentrator to construct an optical collecting system, so tile solar energy can be focused on said optical concentrator through the reflecting by said spherical or aspheric reflector, meanwhile the reflecting coatings coated on the surfaces of said spherical or aspheric reflectors can reflect the useful part of the solar light to the optical concentrator, but not the harmful part (such like ultraviolet below 400 nm in wavelength) absorbed completely by it, further to transfer it into disposable energy.
