<p>PURPOSE: To provide a variable color lighting system, which is hard to receive the influence of dispersion of a part such as a color sensor and which can accurately obtains the desirable light color. CONSTITUTION: When a desirable color temperature is set by a illumination light setting unit 6, the reference value for compensation quantity of dimming and the color temperature of each light source 2R, 2G, 2B corresponding to the command from the illumination light setting unit 6 are respectively output. The output reference value is compared with the real value signal output from a detecting unit 3, which is provided inside of a luminaire 1, by a comparing and computing unit 8, and the comparing and computing unit 8 informs the quantity of correction to a correcting unit 9. The correcting unit 9 received that command and corrects the quantity of dimming of each light source 2R, 2G, 2B output from a light quantity data memory unit 7. The corrected quantity of dimming is converted to the dimming signal by a dimming signal generating unit 5, and sent to dimmers 4R, 4G, 4B, and the optical output of each light source 2R, 2G, 2B are adjusted.</p> |
