<P>PROBLEM TO BE SOLVED: To provided an indirect lighting system capable of obtaining indirect light with a blue-color wavelength component in the vicinity of 440 to 490 nm further effectively reduced with a simple structure, in the case of use of white-color LEDs as a light source. <P>SOLUTION: By structuring the light source 14 with white-color LEDs 12 and red-color LEDs 13 mingled in the indirect lighting device 10 carrying out illumination with indirect light L with the light from the light source 14 reflected on a reflecting surface 15, the illumination is carried out by the indirect light L with a relative specific energy volume of wavelength components of 440 to 490 nm by the light from the white-color LEDs 12 reduced by the light from the red-color LEDs. <P>COPYRIGHT: (C)2012,JPO&INPIT |
