| Abstract: | With the development of LED lighting industry and the technology of LED driver power supply, LED driver with dimming function play an important role in LED lighting applications and has higher requirements for dimming performance gradually. The article studied the strobe LED driver with high-efficiency,low-ripple and dimming features. It not only meets the requirements of low ripple and current, but also makes the LED lamp no flicker,changing evenly and softly of brightness and adapting the requirements of different light curve in the dimming process. |
