<p>PROBLEM TO BE SOLVED: To establish a dimming control system which can make adjustment of the correction factor without requiring significant labor. SOLUTION: A dimming control system comprises an illuminance measuring terminal unit 2 to measure the surrounding illuminance and output the obtained illuminance value, a dimming control device 1 equipped with a control part 1b and a forced setting part 1f and also a correction factor setting part 1d, a dimming switch 4 to output a rise signal or a fall signal, and a dimming output terminal unit 3, wherein the control part 1b calculates the presumed illuminance value from the given illuminance value and correction factor and determines the dimming output value from the presumed illuminance value and the target illuminance value while the forced setting part 1f raises and sinks the dimming output value on the basis of the rise signal and fall signal. The dimming control device 1 has a signal distribution part 6 which outputs the rise and fall signals from the stitch 4 to the forced setting part 1f in the operation mode, and in the setting mode, outputs the signals to the correction factor setting part 1d, which should make setting of the correction factor on the basis of the rise and fall signals.</p> |
