英文摘要：

LED is a trend of development and application of the light source in future,the design of LED drive is a new technology in lighting field.The main function of LED driver in a certain condition,no matter the input and output voltages change,can stabilize the current flowing through the LED.Characteristics of LED and its driving device,from theory to design,are deeply discussed.The design uses double supply,dual output charge mode,and consists of embedded computer control module,control of the constant current source circuit with large power triode as the core.Dual power supply of the original intelligent contactless electronic switching power supply automatically,system can also be used for battery power detection and automatic charging.This design was also tested by STC （The Hongkong standards and Testing Center）,about the ultimate of magnetic radiation leakage,the data show that the design is successful.
