Abstract
A light distribution device has a first light-guiding cable for transmitting light rays, a number of second light-guiding 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-guiding cable. The light coupler has a surface similar to that of a part composing the light-receiving ring-plane of the second light-guiding cables and makes a circular motion along the light-receiving ring-plane at a constant relation thereto.
