Abstract

A server device can periodically obtain information concerning illuminance of ambient light from light sensors associated with light sources, and can obtain respective brightness level values associated with respective brightness levels of the light sources. The server device can calculate an illuminance value associated with the illuminance of the ambient light based on the information, determine an adjusted brightness level value for the light sources based on the illuminance value, and determine transition times and transition rates based on the respective brightness level values and the adjusted brightness level value. The server device can cause the respective brightness levels to change according to the adjusted brightness level value, the transition times, and the transition rates, where the transition times and the transition rates are to be used to transition the respective brightness levels of the light sources from the respective brightness level values to the adjusted brightness level value.
