A linear constant current LED driver circuit

Wenxiang Chen

Open publisher page 1 citations

Abstract

With increasing demands in energy-saving,durable and low-cost lighting equipments,the research and application on LED light soure is becoming widely spread.However,due to high costs and instability of its driver,LED source light has not been universally applied.Based on studying in LED characteristics,this article designed a linear constant current LED driver circuit of high stability and low-cost and so on.It has the characteristics of simple structure,high efficiency,little size.It is tested that this driver circuit can realize well control of constant current.The efficiency of this circuit is more higher,and the temperature of LED junction is more lower.In short,the LED control characteristic gets improvement.
