PURPOSE: To make it possible to conduct visible illumination against wide range directions by composing a transparent resin-made light radiating body, which radiates light transmitted by an optical fiber bundle, of a cone shape portion and a cylinder shape portion. CONSTITUTION: The end face of a transparent resin-made light radiating body 2 and the end face of an optical fiber bundle 3 are mutually connected by a connection jig 4 so as to transmit incident light from the other end face of the optical fiber bundle 3 to the light radiating body 2. The connection jig 4 side of the light radiating body 2 is formed into the cylinder shape, its tip is formed into the cone shape, and the cone shape portion is sand blast working- treated. Thereby, the incident light on the light radiating body 2 is radiated from the cone shape portion so that it becomes possible to conduct visible illumination against wide range directions. |
