ABSTRACT:
A self-light-emitting indicating apparatus including an enclosure formed by combining a pair of opposing semi-tubular bodies, each having first and second support members positioned at both ends; first and second panels fixed on the first and second support members respectively, at least one of the first and second panels having a plurality of through-holes and/or having a sign indicating portion; a plurality of optical fibers contained in a container portion defined by the enclosure and the first and second panels, each having one end inserted and fixed in one of the plurality of through-holes provided in at least one of the first and second panels, and a light emitting diode contained in the container portion, arranged adjacent to the other end of the plurality of optical fibers which are bundled and cut, and having an optical leakage preventing means. When the light from the emitting diode is to be transmitted to the adjacent number of optical fibers, optical loss can be suppressed by the optical leakage preventing means, and in addition, light points at the rear ends of the optical fibers can be arranged along the periphery of the existing sign board, so that existence of a fire hydrant is made readily visible.
