ABSTRACT:
The present invention comprises a planar fluorescent solar concentrator having a circular band portion within said concentrator toward which incident solar radiation is redirected. Optically coupled to said circular band portion is an optical means comprising an axially symmetrical body of light transmitting material having a circular band at one end for the receipt therein of radially directed electromagnetic radiation, said optical means including a body portion, having a coating on the exterior surfaces thereof and a generally circular second end. Light radially directed in said circular band at said first end is internally reflected in said body portion and directed toward said second end, whereby the light leaving that circular second end is distributed substantially uniformly over the entire area thereof.
