Abstract:
A method and system of flicker suppression for an LED 26. The method includes providing a power supply 10 for supplying current to the LED 26. The power supply 10 includes a flicker suppressor 50 and is responsive to a dim command signal. The method further includes receiving the dim command signal at the power supply 10, switching the current on and limiting the current to maintain LED light output below 110 percent of the LED light output corresponding to the dim command signal.
