<P>PROBLEM TO BE SOLVED: To provide a light-emitting tile device that can emit light for a long time with sufficient brightness and perceive certainly regardless of sunset time and brightness of the illumination light. <P>SOLUTION: The light-emitting tile device includes a light-emitting tile (11) which is constructed of a tile body (11A) that is formed using a light transmissive material and has a recess formed at the bottom face, a light-emitting layer (11C) that is formed at the bottom recess (11B) of the tile body and is made of a material including a luminous material, and a backlight light source (11F) that is arranged at the back of the light-emitting layer and irradiates light toward the light-emitting layer, and a power supply unit (12) which is constructed of a solar panel (12A) to generate an electromotive force by receiving light and a power supply circuit that stores the electromotive force of the solar panel to give it to the backlight light source, and is exchangeably installed in separation from the light-emitting tile. <P>COPYRIGHT: (C)2013,JPO&INPIT |
