Abstract
A light-emitting diode ('LED') lighting unit includes an operational, a sense resistor electrically connected to the input of the operational amplifier, a first field effect transistor ('FET') whose gate is electrically connected to the output such that the input voltage at the gate of the first FET rises and falls with the output voltage, a second FET whose gate is electrically connected to the output such that the input voltage at the gate of the second FET rises and falls with the output voltage, and a string of LED lights connected such that when the voltage across the string drops below a level to operate, the voltage across a sense resistor drops, causing the operational amplifier to increase its output until the input voltage at the gate of the second FET increases allowing one bank of LED lights to operate.
