The LED illumination has extremely high luminous efficiency, which is5 or 10 times of incandescent, 2 times of the traditional energy-saving lamps and 1.5 times of high-pressure sodium lamp. It has been widely used in the lamp products of lighting and decoration. At present, the biggest problem that the LED lighting products facing is the stability and reliability of LED drive circuit. The paper tries to explore the scientific and technical standards and test schemes of LED drive technology parameters, which has a certain significance of improving reliability and safety of LED lighting technology.
