PURPOSE:To hold the atmosphere of a site when lighting both a variable color lighting system and an incandescent lamp or a high luminance discharge lamp or the like by controlling the mixed color of the varibale color lighting system in response to the lighted state of a point light source so that it agrees with the color of light of the point light source. CONSTITUTION:When power switches 2, 3 are turned on to light an incandescent lamp 13 and fluorescent lamps 12R, 12G, 12B simultaneously, the address input terminal A13 of a toning data storage portion 9 is changed and all color data are set to white data of the same color temperature as natural lights. Therefore, predetermined color data are output from the storage portion 9 simultaneous with lighting of the incandescent lamp 13 regardless of the set value of a color setting portion 6 and are converted into dimming signals by a toning data converted output portion 10. Thereby dimming control of lighting devices 11R, 11G, 11B can be performed in response to lighting of the incandescent lamp 13 and the color temperatures of the mixed color light of the incandescent lamp 13 and the fluorescent lamps 12R, 12G, 12B become the same. Therefore the atmosphere of a site is not deteriorated. |
