Abstract:
An LED lighting system including a first group of LEDs, a second group of LEDs, and a controller. The first group of LEDs and the second group of LEDs are configured to be independently driven by a first LED drive signal and a second LED drive signal, respectively. The controller is configured receive a dimming signal from a dimmer having a preheat function. The controller is also configured to compensate the dimming signal for the preheat function of the dimmer to generate a compensated dimming signal, generate the first LED drive signal based on the compensated dimming, and generate the second LED drive signal based on the compensated dimming signal. The first LED drive signal is then transmitted the first group of LEDs and the second LED drive signal is transmitted to the second group of LEDs.
