SOLAR LIGHT RADIATOR: OPTICAL LIGHT CONDUCTOR ROD DIVIDED INTO PLURAL SECTORS THE DIVISIONS BETWEEN THE SECTORS BEING REFLECTION SURFACES

摘要

A light radiator comprises a cylindrical optical conductor rod in which light rays are guided into the optical conductor rod from one end portion or both end portions thereof. The guided light rays into the optical conductor rod are radiated from the optical conductor rod in a radial direction. The optical conductor rod is divided into plural pieces in radical direction along its center line as a common line and the respective division surfaces are provided with a reflection surface.
