Zusammenfassung:An illuminating device includes a plurality of kinds of LEDs that emit light having different color temperatures; a plurality of LED lighting circuits that independently light the LEDs for each color temperature of emitted light; and a control unit that selects a first control changing illuminance of the LEDs as a whole by controlling the lighting of the LEDs and a second control changing the colors of light of the LEDs as a whole by controlling the lighting of the LEDs, and corrects an illuminance difference generated before and after the second control.
