Abstract
An LED light temperature control system includes a dimmer switch comprising a single power input, an output signal, and an control device configured to vary the duty cycle of the output signal. The LED light temperature control system further includes a light controller configured to receive the output signal from the dimmer switch. The light controller has a first light output signal configured to power a first group of LEDs and a second light output signal configured to power a second group of LEDs. The light controller is configured to vary the duty cycle of the first light output signal proportionate to the duty cycle of the dimmer switch output signal. The light controller is further configured to vary the duty cycle of the second light output signal inversely to the duty cycle of the dimmer switch output signal.
