A solar ray device for illumination is disclosed. The device comprises a solar ray collecting device and an illuminator. The solar ray collecting device has a plurality of optical lenses for focusing solar rays, a plurality of light-guiding cables with their light-receiving ends disposed at the focal points of the optical lenses, and a sensor for detecting the direction of the sun's rays and for creating a control signal causing the optical lenses to be directed toward the sun and thereby introducing the sun's ray into the light-guiding cables. The illuminator receives the light rays transmitted through the light-guiding cables and radiates the same through its lenses disposed opposite the light-emitting ends of the light-guiding cables. |
