SONNENSTRAHLEN-SAMMELVORRICHTUNG

摘要

A solar ray-collecting device comprises a Fresnel lens 2, an optical coupling 20 made of a tip-cut conical light guide, and an optical cable 5. The solar rays focused by the lens 2 are received at the large end 20a of the optical coupling and discharged from the small end 20b thereof and guided into the cable 5. The light-emitting end 20b of the optical coupling is adhesively joined to the light-receiving end of the optical cable 5 by the use of an optical paste. <IMAGE>
