Abstract
In accordance with the presently claimed invention, circuitry and a method are provided for using a voltage to drive a light emitting diode (LED) load including one or more LEDs. The incoming voltage is switched and inductively conditioned to drive the LED load in such a manner as to cause the LED load to appear as a substantially linear resistive load, thereby maximizing the power factor presented to an AC power grid serving as the source of the input voltage.
