PROBLEM TO BE SOLVED: To provide an lighting system capable of giving presence by repeating a specified pattern in which the illuminance of a white lamp as a second illumination lamp is increased/decreased with the passage of time. SOLUTION: In an lighting system having incandescent lamps 16 to 19, each of whose illuminance is changed by a specified pattern and an ultraviolet ray lamp 15, since only the ultraviolet ray lamp 15 is lit during an initial period and the incandescent lamps 16 to 19 are kept OFF, a picture P is dark as a whole and a crescent-shaped graphic P2 coated with paint lit or reflected by the light of the ultraviolet ray lamp 15, the drawing P3 of the light of a light house and the drawing P4 of a portion in which a moon light is displayed on the sea surface are only visible being lit respectively. Thus, the picture P is recognized as a night scene as a whole. When the illuminance of each of the incandescent lamps 16 to 19 is increased after the passage of a specified period, each of the drawings P2 to P4 is invisible and thus the picture is recognized as a day scene as a whole. |
