PROBLEM TO BE SOLVED: To provide a luminous body requiring no wiring, easy to install, excellent in efficiency, and compatible with the environment by providing a solar battery on a thin film luminescence section to save power, and allowing the luminescence section to illuminate by the electricity obtained by the solar battery. SOLUTION: A battery C is connected to a luminescence section B and a solar battery D via cables E, the electricity generated by the solar battery D under sunshine is stored until night, and a luminous body A can be independently arranged without receiving electricity from the outside. The cable E can be connected to the outside as required, excess electricity can be sold to a power company, or required electricity can be supplied. The capacity of the battery C depends on the illumination area of the luminescence section B, and it is preferable that the battery C can store the required quantity of electricity for the luminescence section B to illuminate throughout the night when the luminous body A is supplied with no electricity from the outside. |
