Abstract
A lighting system includes a power converter connected to mains voltage and configured to provide a driving current responsive to a control signal. A voltage measurement circuit is configured to provide a voltage sense signal indicative of an amplitude of the mains voltage. A light-emitting diode (LED) module includes at least one string of LEDs that emit light responsive to the driving current, and is configured to detect an LED current through the at least one string and output a current feedback signal indicative of the detected LED current. A driver controller is configured to output the control signal responsive to the voltage sense signal and the current feedback signal.
