  • Electrical control for an LED light source, including dimming control
    Patent number: 6683419
    Abstract: A control for a light with an LED light source. The LED light source mimics an operation of an incandescent light source with respect to a dimming control. The LED light source includes at least one LED. A power source provides power to the at least one LED. A sensing element senses at least one of voltage and current at the at least one LED and outputs a feedback signal to the power source based on the sensed at least one of voltage and current. A control circuit is connected to the sensing element and controls the feedback signal output by the sensing element. That control circuit can control the feedback signal output by the sensing element to simulate a dimming operation of an incandescent light source.
