ABSTRACT:
Light radiator for diffusing and radiating light rays which have been transmitted through an optical cable comprises a transparent cylinder, an optical conductor for guiding light rays into the cylinder, an optical means movably accommodated in the cylinder for reflecting the light rays guided into the cylinder and radiating the light rays outside of it, and a driving means for moving the optical means along the axis of the cylinder. The driving means comprises optical oil in the cylinder and a liquid pump having one end communicating with one end of the cylinder and another end communicating with the other end of the cylinder. The liquid pump comprises a cylinder of a larger diameter than that of the cylinder, a piston plate partitioning the large-diametered cylinder and moving inside of it, and a moving device for moving the piston plate, wherein one end of the large-diametered cylinder communicates with one end of the cylinder and the other end of the large-diametered cylinder communicates with the other end of the cylinder.
