Claim 7:
8. A method of driving a light-emitting diode (LED) light source, comprising:
receiving, by an LED dimmer control circuit, output intensity data representative of an output intensity for one or more LED light sources conductively coupled to the LED dimmer control circuit;
determining, by the LED dimmer control circuit, an ON time (TON) to supply voltage to the one or more LED light sources based on the received output intensity data;
starting, by the LED dimmer control circuit a timer to provide an elapsed time (T);
causing, by the LED dimmer control circuit, a controllably conductive device disposed between a power source and the one or more LED light sources to transition to a CONDUCTIVE state;
responsive to the elapsed time meeting or exceeding a first time threshold (T≥T1), introducing, by the LED dimmer control circuit, a current feedback signal to the LED dimmer control circuit;
responsive to the elapsed time meeting or exceeding a second time threshold (T≥T2), interrupting, by the LED dimmer control circuit, the current feedback signal to the LED dimmer control circuit; and
responsive to the elapsed time meeting or exceeding the ON time (T≥TON), causing, by the LED dimmer control circuit, the controllably conductive device to transition to a NON-CONDUCTIVE state.
