An electric energy supply device for powering at least one lighting device may include a first wireless communication module, a multiplexing module and a driving module. The first wireless communication module may receive or transmit a first control signal based on the first wireless network communication protocol. The multiplexing module may identify the communication protocol type of the first control signal. The driving module may drive the light device according to the first control signal. According the communication protocol type, the multiplexing module may determine whether to control the driving module to drive the lighting device according to the first control signal or transmit the first control signal to the first controlled device corresponding to the communication protocol type to remotely control the first controlled device by using other electric energy supply devices as the data bridge path after receiving the first control signal via the first wireless communication module.
