PURPOSE:To prevent the collected solar light from affecting adversely the human body, animals and vegetables by using a part where the passage of UV rays is prohibited as a part of the optical path of a solar light collector. CONSTITUTION:A solar light collector 10 formed with a support frame 13 mounted with a sensor 12 for the direction of solar light and many lenses 11 in a way as to be directed always toward the direction of the sun by making use of the signal from said sensor 12 is contained in a transparent capsule 3 (a symbol 1 is a base body part), and the light collected at the focal position of the lenses 11 of the collector 10 is transmitted to a desired place by using a photoconductive cable so as to be utilized. A UV absorbent (for example, para- aminobenzoic acid) is incorporated in the capsule 3, the lens 11, the photoconductive cable, etc. in the abovementioned installation to prohibit the passage of the UV rays [UV-C(200-290nm), UV-B(290-320nm)] harmful to living things. |
