摘要：
As a mainstream product in the field of lighting, white LED has replaced fluorescent lamp and incandescent lamp by its significant advantages of unique energy-saving, environmental sustainability, long life and high reliability. The demand of LED is high to the stability of the power supply current, and it needs constant current power supply, or the LED light is easy to damage. The system mainly consists of three parts: AC/DC conversion, DC/DC conversion, constant output current control and output instructions. With the LED driving mode improved, the system design uses constant current circuit set up by OPAMP and makes the stability of the output current of the whole system improved.
