A light radiator includes a semitransparent tubular container, a large number of transparent plates arranged in series inside of said tubular container in such a way as to be inclined in the same direction as the axis of said container, a light-guiding, cable-connecting portion provided at one end of the container to connect thereto the output end of a light-guiding cable, a lens inserted between the light-guiding, cable-connecting portion and the transparent plate and a motor for rotating the tubular container. The transparent plates each have at least a partial reflecting surface and their reflecting surfaces are made larger in size because of being farther from the lens in order to reflect a substantial, even amount of light rays. A light radiator capable of radiating solar rays which are focused by lenses introduced into a light-guiding cable and of being transmitted therethrough to the light radiator for radiating them to such objects as plants etc. |
