Abstract

Abstract A light radiator has a tubular body bearing at the center of one end a removable light-emitting end of a fiber optic cable and having at the other end a large number of light-guiding rods arranged tightly and parallel to each other. The light-guiding portion includes two groups of light-guiding rods, the first group consisting of rods having their light-emitting end-surfaces on the same plane and the second group consisting of rods having their end-surfaces on a plane lower than that of the first group's rods. Each light-guiding rod of the first group and each light-guiding rod of the second group are in contact with each other at least on one side and each light-guiding rod of the second group has a tapered, concave-shaped output end.
