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.

A power conversion apparatus, which converts power of a DC power supply and provides it to the loading, includes a transformer, an electronic switch, a leakage energy recycling circuit, and a output circuit. The transformer has a primary winding, which receives the power, and a secondary winding, which outputs the converted power. An end of the electronic switch is electrically connected to the primary winding; another end thereof is electrically connected to the DC power supply. The leakage energy recycling circuit is electrically connected to the primary winding, and repeatedly and alternatively outputs power of positive and negative voltage. The circuit receives and stores leakage energy of the transformer, and feedbacks it to the transformer. The output circuit is electrically connected to the secondary winding to receive the converted power and to provide it to the loading.
