Patent ID: 7990080

Claim:
A system for controlling multiple light sources, the system comprising: a controller 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, wherein each light circuit is configured for controlling a light source included in the light circuit; a digital to analog converter (DAC) connected to the controller, the DAC configured for receiving the digital luminance signal and the encoded address for each light circuit from the controller, converting the digital luminance signal into an analog luminance signal, and for outputting the analog luminance signal according to the encoded address; and at least one power amplifier connected to the DAC, each power amplifier corresponding to one light circuit and configured for receiving the analog luminance signal from the DAC, and amplifying the analog luminance signal for the light circuit so as to drive the light circuit to control a light source corresponding to the light circuit; wherein the controller connects to a computer for receiving a plurality of communication parameters of a communication between the computer and the controller, and displaying errors when the communication parameters are incorrect, the errors comprising an invalid serial port number for the computer, an error of invalid access information, and a data transmission error between the computer and the controller.
