Thereby, the user 10 can index smooth waking from the difference between the waking time and the actual waking time, the shallowness of sleep, and the like, and the user can be awakened more clearly by adjusting the waking control mode. It will be obtained. At this time, the display unit 14 displays the wake-up setting time and the actual wake-up time. Thereby, it can help a user arrange sleep rhythm.

  In the sleep control mode, the display unit 14 averages and displays the extinguishing time of the luminaire 1 over a predetermined period as illumination information (not shown). In addition, when the sensor unit 6 detects the user's sleep, the information extraction unit calculates the comfort level related to the user's sleep from the time from the start time of the sleep control mode to the sleep time of the user 10 detected by the sensor unit 6. Is displayed on the display unit 14 (not shown). In addition, as shown in FIG. 6, the display part 14 can also display the average value of actual sleep time. Thereby, the user 10 can generally know the average of the time taken to fall asleep, and can be used, for example, to review how to spend time before taking a rest or to secure the actual sleep time. In addition, the display part 14 displays the time when the lighting fixture 1 was lighted, or the frequency | count of lighting in the period from the end time of the sleep control mode to the user's 10 wake-up time (refer FIG. 6).

  Further, the input unit 13 of the terminal 11 can input a sleep feeling such as a feeling of awakening of the user 10 when getting up. For example, as shown in FIG. 7 above, the awakening comfort level (for example, a five-star rating in the figure) can be input. And the user 10 can know clearly the relationship between the user's 10 feeling about sleep / wake-up and the lighting environment by comparing the correlation between the comfort level and the lighting information.
