ABSTRACT:
A light distribution device has a first light-guide cable for transmitting light rays, a number of second light-guide cables having light-receiving ends arranged together to form a light-receiving ring plane, a driving means for rotating the light-emitting end of the first light-guiding cable around the light-receiving ring-plane, a light coupler secured at the light-emitting end of the first light-guide cable. The light coupler has a surface similar to that of a part composing the light-receiving ring-plane of the second light-guide cables and makes a circular motion along the light-receiving ring-plane at a constant relation thereto. The light-receiving ring facing to the light coupler is divided into a plurality of blocks, each of which consists of a given number of secondary light-guide cables.
