A lighting device 2 that emits the wake-up light L1, a control device 3 that controls the output of the wake-up light L1 emitted from the lighting device 2, and an interface device 4 that is operated by the user and inputs at least the wake-up time； The illuminating device 2 includes an output variable device 24 that changes the output of the wakeful light to be irradiated and a color temperature variable device 24 that changes the color temperature of the wakeful light L1, and the control device 3 is irradiated from the illuminating device 2. A light output control unit 31 that controls the output variable device 24 so as to increase the output of the awakening light L1 from the awakening operation start time toward the awakening time, and a first time point after a first predetermined time has elapsed from the awakening operation start time. The color temperature of the wake-up light L1 between the first time and the wake-up time is between the second time and the first time before the second predetermined time shorter than the first predetermined time than the first time. As it is higher than the color temperature of 醒光 L1, comprising a color temperature control unit 31 for controlling the color temperature variable device 24. [Selection] Figure 2覚醒光Ｌ１を照射する照明装置２と、照明装置２から照射される覚醒光Ｌ１の出力を制御する制御装置３と、ユーザによって操作され、少なくとも覚醒時刻を入力するためのインターフェース装置４を備え、照明装置２は、照射する覚醒光の出力を変化させる出力可変装置２４と、覚醒光Ｌ１の色温度を変化させるための色温度可変装置２４を備え、制御装置３は、照明装置２から照射される覚醒光Ｌ１の出力を覚醒動作開始時刻から覚醒時刻に向けて増加させるように出力可変装置２４を制御する光出力制御部３１と、覚醒動作開始時刻から第１所定時間経過した第１の時点から前記覚醒時刻までの間における覚醒光Ｌ１の色温度が、第１の時点よりも第１所定時間よりも短い第２所定時間前の第２の時点から第１の時点までの間における覚醒光Ｌ１の色温度よりも高くなるように、色温度可変装置２４を制御する色温度制御部３１を備える。【選択図】図２
