Abstract

PURPOSE:To eliminate a chromatic aberration, and to improve the profitability, comparing with a device which has used an optical fiber, by combining an optical device consisting of a reflection mirror for condensing the solar light to parallel rays, and an optical duct for transmitting solar parallel rays to a necessary place. CONSTITUTION:An optical device A which has been constituted so as to be always opposed regularly to the sun by a sun tracking device consists of a concave type parabolic reflection mirror 1 for a condensing, and a concave type parabolic reflection mirror 2 which has been installed so that its focal position becomes the same position as that of the reflection mirror 1 so as to return the condensed light to parallel rays. Solar parallel rays which have been reflected by the reflection mirror 2 and have transmitted through a through-hole of the center part of the reflection mirror 1 are changed as to its track by two pieces of plane reflection mirrors 3, 4, and led into an optical duct B which has been provided vertically. The optical duct B transmits concentrated solar parallel rays to a necessary place by a linear part B1 in which a reflection material has been stuck to the inside surface, and a bending part B2 which can change freely an optical path by adjusting an angle of a plane mirror 5 which has been provided in the duct.
