Improved Method and Apparatus for Dimming a Lighting Device

The present invention relates to a method and an apparatus for controlling illumination of a light device such as a high power light emitting diode. Electrical power is alternately switched to the HP-LED via an energy storage arrangement, such as an inductor, and away from the HP-LED. Energy is conserved in the inductor by applying a short circuit across the inductor as the power is switched away from the HPA-LED.
