Abstract

A light reflecting device capable of independently or synthetically using light rays delivered by at least two light-guide cables and of selectively changing the amount of light rays in accordance with the conditions of the object to be radiated, is described. The device has a pair of light-reflecting plates disposed symmetrically about the center axis and facing in opposite directions. Each of the plates are inclinably, rotatably and integrally mounted. Futhermore the device has a driving means for moving the pair of reflecting plates back and forth in the direction of their reflecting surfaces and a pair of mounting means for mounting the corresponding light sources for radiating parallel light rays toward the corresponding reflecting surfaces of the reflecting plates and along the reflecting plates'"'"' shifting axis.

Claims

1. A light reflecting device for reflecting light from light sources, comprising a pair of light-reflecting plates, disposed symmetrically about the center axis and facing in the opposite directions, each of said plates being inclinably, rotatably and integrally mounted, a driving means for moving said pair of reflecting plates back and forth in the direction of their reflecting surfaces and a pair of mounting means for mounting said light sources for radiating parallel light rays toward the corresponding reflecting surfaces of the reflecting plates and along the reflecting plates'"'"' shifting axis.

2. A light-reflecting device according to claim 1, characterized in that said paired light-reflecting plates are inclinable in the direction of their shifting axis.

3. A light-reflecting device according to claim 1 or 2, characterized in that said paired light reflecting plates are rotatable about their shifting axis.
