<p>PROBLEM TO BE SOLVED: To establish a dimming control system which can make constant control of illumination precisely without causing drop of the illuminance resolution of a dimming control device even if the correction factor enlarges. SOLUTION: A dimming control system comprises an illuminance measuring terminal unit 2 to measure the surrounding illuminance by the specified range and emit the obtained illuminance as output, a dimming control device 1 equipped with a control part 1b and a correction factor setting part 1d, and a dimming output terminal unit 3 to output the signal for controlling the dimming output of a luminaire on the basis of the dimming output value, 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 obtained presumptive illuminance value and the given target illuminance value. The illuminance measuring terminal unit is equipped with a range setting part 5 which sets the range on the basis of the correction factor.</p> |
