A light radiator for effectively diffusing radiating light rays, transmitted through an optical conductor cable or the like, out of the optical conductor cable. The light radiator includes a transparent cylinder positioned almost horizontally, an optical conductor for guiding light rays into the cylinder, an optical means movably installed in the cylinder for reflecting the light rays guided into the cylinder and for radiating the reflected light rays out of the cylinder and driving means for moving the optical means along an axis of the cylinder. The optical means includes a cylindrical member having an outer diameter approximately equal to an inner diameter of the cylinder. One end surface of the cylindrical member is inclined in relation to an axis line of the cylindrical member and is formed as a reflection surface. A cavity is provided at a longer-axis side of the cylindrical member to eliminate the need for complex regulation means to regulate the direction of reflection of the light rays. |
