<P>PROBLEM TO BE SOLVED: To provide a luminous ceiling light shade used for ceilings of various buildings, ceilings in elevator cages, and ceilings of railway vehicles which has an emergency light lighting function at the time of power failure, and by utilizing light storage emission, emits illumination light close to that of a white fluorescent lamp, and can continue for a long time, to provide a lighting system thereof, and to provide a lighting method thereof. <P>SOLUTION: The luminous ceiling light shade (1) and the luminous ceiling light shade system (10) use a light diffusive laminate (2) in which a fiber cloth (3) is used as a substrate and a light propagation translucent resin layer (4) is provided on its one side, and a light-storage luminous layer (5) containing a fluorescent whitening compound is installed on at least one layer of the light propagation translucent resin layer (4), and a near ultraviolet ray light-emitting diode (6) is arranged opposed to the end part cross-section of the light diffusive laminate (2) to form an illumination system. Thereby, at the time of power failure, the light-emitting diode (6) is made to generate light by a battery and emits the light from the end part cross-section of the light propagation translucent resin layer (4), and the whole face of the light-storage luminous layer (5) is made to emit white fluorescent light to serve as an emergency light illumination. <P>COPYRIGHT: (C)2010,JPO&INPIT |
