Abstract: In the rapid development of Electronic Science and technology today, with people's living standards increasing and to explore the deepening of the material world, people of power transmission and the transmission quality also has the new requirements.This paper designs a simple wireless power supply system based on the principle of electromagnetic induction., the system comprises a power supply module and the LED lighting module, by way of electromagnetic coupling solves the energy transmission of the sending module and illumination module, wireless power transmission is realized. The LED lighting module comprises a bridge rectifier, a filter and five LED lamps, and an electric energy transmission through an induction coil. LED light intensity control, in addition, the photosensitive resistance has limited the power of the receiving end. Through the detection of the LED light intensity and the data feedback to the energy sending module, the power of the transmitting module can be controlled.

Key words: wireless power supply, electromagnetic coupling, LED lighting
