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.
A light radiator comprising a hollow transparent cylinder means, an optical conductor means for guiding light rays into said transparent cylinder means through one end of said transparent cylinder means, an optical means movably accommodated in said transparent cylinder means for reflecting said light rays guided into said transparent cylinder means from said optical conductor means and radiating said light rays outside of said transparent cylinder means, a pump means, said pump means comprising a pump cylinder means and a piston plate means partitioning said pump cylinder means and axially movable in said pump cylinder means, a first pipe means connected with one longitudinal end portion of said pump cylinder means and with one longitudinal end portion of said transparent cylinder means, a second pipe means connected with another longitudinal end portion of said pump cylinder means and with another longitudinal end portion of said transparent cylinder means, optical oil in said pump cylinder means, in said first and second pipe means and in said transparent cylinder means, said pump means further comprising magnetic means for moving said piston plate means in one axial direction in said pump cylinder means to move optical oil in said first pipe means in one direction and optical oil in said second pipe means in one direction to thereby move said optical means in said transparent cylinder means in one direction, said piston plate means being axially movable in said pump cylinder means in a second direction opposite to said one direction to move optical oil in said first pipe means in a second direction opposite to said one direction and to move optical oil in said second pipe means in a second direction opposite to said one direction to thereby move said optical means in said transparent cylinder means in a second direction opposite to said one direction.
A light radiator comprising a hollow transparent cylinder means, an optical conductor means for guiding light rays into said transparent cylinder means through one end of said transparent cylinder means, an optical means movably accommodated in said transparent cylinder means for reflecting said light rays into said transparent cylinder means from said optical conductor means and radiating said light rays outside of said transparent cylinder means, a drive means, first pipe means connected with said drive means and with one end portion of said transparent cylinder means, a second pipe means connected with said drive means and with another end portion of said transparent cylinder means, optical oil in said drive means, in said first and second pipe means and in said transparent cylinder means, said drive means comprising a pump cylinder means and a piston plate means partitioning said pump cylinder means and axially movable in said pump cylinder means, said drive means further comprising magnetic means for moving said piston plate means in one axial direction to move optical oil in said first pipe means in one direction and optical oil in said second pipe means in one direction to thereby move said optical means in said transparent cylinder means in one direction, said piston plate means being axially movable in said pump cylinder means in a second direction opposite to said one direction to move optical oil in said first pipe means in a second direction opposite to said one direction and to move optical oil in said second pipe means in a second direction opposite to said one direction to thereby move said optical means in said transparent cylinder means in a second direction opposite to said one direction.
