A system for collecting solar energy which comprises a thin faceplate made of a large number of optical fibers having respectively a diameter ranging from 0.5 micron to 2.0 micron tied up coherently in a bundle vertically to the plane of the faceplate, and a means for focusing the rays departing from the optical fibers of the faceplate. The faceplate enables to let solar rays entering into the optical fibers from all directions within the numerical aperture of the fibers pass through the fibers to let rays parallel to the principal axis of the faceplate depart from the fibers. Accordingly, the system enables to collect solar energy with a high collecting efficiency with no special means for strictly following the sun. FIG. 4 is a vertical sectional view of a system of this invention, wherein 1 is faceplate, 2 optical fibers composing the faceplate, 3 concave parabolic mirror, 4 convex parabolic mirror, 9 a bundle of optical fibers for transmission.
A system for collecting radiant energy of sunlight which comprises a faceplate for receiving parallel rays of sunlight which is a thin plate made of a large number of optical fibers having respectively a diameter ranging from 0.5 micron to 2.0 micron tied up coherently in a bundle vertically to the plane of the faceplate, and a means for focusing the parallel rays departing from the optical fibers of the faceplate to concentrate the radiant energy outside the system.
A system for collecting radiant energy of sunlight which is compounded with a number of units, the unit of which comprises a faceplate for receiving parallel rays of sunlight which is a thin plate made of a large number of optical fibers having respectively a diameter ranging from 0.5 micron to 2.0 micron tied up coherently in a bundle vertically to the plane of the faceplate, a means for focusing the parallel rays departing from the optical fibers of the faceplate, and a bundle of optical fibers for transmission which is connected with the focal area of the focusing means, and the bundles of optical fibers for transmission are collected to a remote destination.
