Abstract
A system for controlling multiple light sources is provided. The system includes a controller, a digital to analog converter (DAC), and at least one power amplifier. The controller is configured for receiving light control data for at least one light circuit, and for determining a digital luminance signal and an encoded address for each light circuit according to the light control data. The DAC is connected to the controller and configured for receiving the digital luminance signal and the encoded address for each light circuit, converting the digital luminance signal into an analog luminance signal, and for outputting the analog luminance signal according to the encoded address. Each power amplifier is connected to the DAC, and is configured for amplifying the analog luminance signal for the light circuit so as to drive the light circuit to control a corresponding light source.
