A light source device for effectively diffusing and radiating light rays which have been transmitted through an optical conductor cable or the like, to the outside of the optical conductor cable. The light source device contains a light radiator comprising a transparent cylinder, an optical conductor for guiding light rays into the cylinder through one end of it, optical means movably accommodated in the cylinder for reflecting the light rays guided into the cylinder from the optical conductor and radiating the light rays outside of the cylinder, and driving means for moving the optical means along an axis direction of the cylinder, a large number of the cylinders being arranged crosswise in a state of grille. |
