Classification: CPC H  Y | IPC H

Claim 7:
8. A light-emitting diode (LED) lighting control method, comprising:
responsive to receipt of an input signal that includes data representative of a requested change in brightness of one or more operatively couplable LED chains:
determining, by LED lighting control circuitry, a current time of day;
determining, by the LED lighting control circuitry, 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
determining, by the LED lighting control circuitry, a target color temperature output 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 includes 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.
