Abstract

PURPOSE: To apply even and high light intensity to solar batteries and reduce the quantity of light deviating from the batteries by making the focal length at each part of the concave mirror gradually shorter at the portions further from the center of the concave mirror.
CONSTITUTION: The distances between the points of intersection of the parallel rays 5 incident to each part of a concave mirror 6 on the optical axis 4 and the center of the condave mirror are made closer to the concave mirror at the portions further from the optical axis 4. Then, the concentration of light at one point on the optical axis may be avoided, the light diffused even to the outer side from the optical axis and the light condensed at nearly even ligyt intensity on a colar battery cell 1. The provision of the solar battery cell 1 in the place further closer to the concave mirror from the closest focal length out of the respective focal lengths of the mirror improves effect further.
