Abstract: A light control system comprises a power connecting port, a host connecting port, a first light connecting port, a second light connecting port, a microcontroller and a power distribution unit. The power connecting port electrically connects to an external power source to provide the power to drive a plurality of light devices. The host connecting port is configured to receive a multimedia signal from a host. The first light connecting port and the second light connecting port electrically connect to a first light device and a second light device respectively. The microcontroller is configured to identify device types and generate two dimming signals according to configurations corresponding to the device types and the multimedia signal. The power distribution unit converts the two dimming signals to two driving signals for controlling the first light device and the second light device to emit colored lights associated with the multimedia signals.
