Claim 15:
16. A non-transitory, machine-readable, storage device that includes instructions that, when executed by an LED dimmer control circuit, causes the control circuit to:
receive output intensity data representative of an output intensity for one or more LED light sources conductively coupled to the LED dimmer control circuit;
determine an ON time (TON) to supply voltage to the one or more LED light sources based on the received output intensity data;
initiate a timer to provide an elapsed time (T);
cause 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), introduce a current feedback signal to the LED dimmer control circuit;
responsive to the elapsed time meeting or exceeding a second time threshold (T≥T2), interrupt the current feedback signal to the LED dimmer control circuit; and
responsive to the elapsed time meeting or exceeding the ON time (T≥TON), cause the controllably conductive device to transition to a NON-CONDUCTIVE state.
