Although not shown, the amount of change in the illuminance of the first lighting device 100 and the second lighting device 200 may be set by curves.

However, within the range of L1 to L4, the illuminance that many users want to fine-tune is not the considerably dark illuminance near L1 or the considerably bright illuminance near L4, but the moderate illuminance near L2 and L3. The illuminance is bright enough. Here, as shown in FIG. 3, if the change amount of the illuminance of the first lighting device 100 and the second lighting device 200 within the range of L1 to L4 is always set with the same inclination, many users The vicinity of L2 and L3, which is desired to be finely adjusted, and the vicinity of L1 and L4, which are not finely adjusted by most users, are equally easy to adjust.

Therefore, by making the amount of change in the illuminance of the first lighting device 100 and the second lighting device 200 in areas where more people want to make fine adjustments smaller than the amount of change in areas where many people do not make fine adjustments, It is possible for the user to easily present the toilet space 10 of his/her preference.

In other words, the change amount of the illuminance of the first lighting device 100 and the second lighting device 200 changed by the control device 400 is L2 to L3 in the range L1 to L4, which is the range in which the user can operate the operation device 300. A generally comfortable range is set by a gentle curve with a large curvature or a straight line with a small slope, and generally uncomfortable ranges such as L1 to L2 and L3 to L4 have a small curvature. It is preferably set by a steep curve or a straight line with a large slope.

Also, as shown in FIG. However, as shown in FIG. 4, the change amount of the first lighting device 100 and the change amount of the second lighting device 200 may be the same.

However, as shown in FIG. 1, when the first lighting device 100 is installed on the ceiling and the second lighting device 200 is installed at a position lower than the first lighting device 100, the first lighting device 100 And the change in the atmosphere of the toilet space 10 felt by the user due to the change in the illuminance of the second lighting device 200 is directed to the first lighting device 100 installed on the ceiling so as to affect the entire inside of the toilet space 10. highly dependent.

Here, by making the amount of change in the illuminance of the first lighting device 100 that greatly affects the change in the atmosphere of the toilet space 10 by changing the illuminance smaller than the amount of change in the illuminance of the second lighting device 200, It is possible for a person to easily direct the toilet space 10 of his/her preference.

3 and 4, the illuminance of the first lighting device 100 and the second lighting device 200 has been described as an example, but the same applies to the color temperature.
