Abstract
A dimming light emitting diode (LED) system comprises an LED driver. A switch-mode power supply controller is coupled to the LED driver to drive an LED light source array. The LED driver is configured to output an LED drive command to the switch-mode power supply controller to dim the LED light source array based on one or more LED parameters. The one or more LED parameters include a photometric response parameter, a gamma parameter, an aging parameter, a temperature parameter, or any combination thereof.
