Abstract
A dimming control and driver for an LED luminaire comprises a shutdown relay connected between an AC source and the driver circuit. The shutdown relay will close above a predetermined control voltage, and will open below the predetermined voltage. The shutdown relay will eliminate parasitic loss by turning the power completely off when the LED luminaire is turned off.
