A light radiator for effectively diffusing and radiating light rays outside of the optical conductor cable through which they were transmitted. The light radiator comprises a transparent cylinder, an optical conductor for guiding light rays into the cylinder, an optical means movably accommodated inside of the cylinder for reflecting the light rays guided into the cylinder and radiating outside of the cylinder, and a driving means for moving the optical means along the axis of the cylinder. The optical means is constructed with a cylindrical transparent member, a surface of one side on which the light rays impinge being formed on a plane and another surface of the other side being formed in a V-shaped concave surface. |
