<P>PROBLEM TO BE SOLVED: To provide an energy-saving light-storage illuminating body capable of being used in place of a light source of a conventional guide board and adapting to power failure without needs of separately setting a light source for that occasion. <P>SOLUTION: The light-storage illuminating body A is provided with a rod-like or a plate-like light guide body 1, and a plurality of LEDs 2 arranged at either end face of the light guide body 1. The LEDs 2 are to be structured of white LEDs 2a and ultraviolet LEDs 2b, and a light-storage layer 3 accumulating light energy of the above ultraviolet LED 2b on a face 1b opposed to a light-emitting face 1a of the light guide body 1, so that, when a light source for lighting the LEDs 2 is interrupted, the light energy accumulated at the light storage layer 3 is to be continuously released as visible light. <P>COPYRIGHT: (C)2010,JPO&INPIT |
