CPC H05B 45/20 (2020.01) [H05B 47/16 (2020.01); H05B 47/19 (2020.01)] | 21 Claims |
1. A light-emitting diode (LED) lighting controller operatively couplable to one or more LED chains, the LED lighting controller comprising:
communications interface circuitry; and
controller circuitry to, responsive to receipt of an input signal that includes data representative of a requested change in brightness of the one or more operatively couplable LED chains via the communications interface circuitry:
determine a current time of day;
determine a current color temperature that corresponds to the current time of day for the one or more operatively couplable LED chains using a first color temperature curve that includes data representative of a first color temperature as a function of a time of day; and
determine a target color temperature that corresponds to the current time of day for the one or more operatively couplable LED chains using a second color temperature curve based on the requested change in brightness of the one or more operatively couplable LED chains;
wherein the second color temperature curve to include at least the target color temperature that corresponds to the determined current time of day; and
wherein a first difference between the first color temperature curve and the second color temperature curve at solar noon is less than a second difference between the first color temperature curve and the second color temperature curve at sunrise and sunset.
