PURPOSE: To provide a lighting system having a plurality of light sources differed in power consumption and light color in which the brightness at a color temperature of about 4200-6500 [K] can be sufficiently provided. CONSTITUTION: Green, red and blue ring fluorescent lamps 2G, 2R, 2B differed in ring diameter are housed in a lighting fixture l in order from a one having a larger ring diameter. This device also has dimmers 4R, 4G, 4B for controlling the dimming level of each light source 2R, 2G, 2B, a dimming signal generating part 5 for setting the dimming level of each light source 2R, 2G, 2B, a light quantity data memory part 7 for storing plural sets of light quantity data, and an illuminating light setting part 6 for selecting the light quantity data. Thus, this device has a plurality of light sources differed in power consumption and light color, and the brightness at a color temperature of about 4200-6500 [K] can be sufficiently provided. |
