Abstract
An appliance is provided herein. The appliance may include a power supply configured to receive Alternating Current (AC) power and supply Direct Current (DC) power, a driver circuit configured to receive the DC power and illuminate one or more light emitting diodes (LED), and a fade control circuit configured to direct the driver circuit to fade the one or more LEDs from an on-state to an off-state in a fade-out operation. The appliance may further include a first switching device configured to direct the fade circuit to perform a fade-out operation while the first switching device is in a first state, and a second switching device configured to maintain AC power to the power supply during the fade-out operation, and further configured to sever AC power to the power supply upon completion of the fade-out operation.
