Abstract：This paper analyzes the features of the traditional LED driver circuit in brief.According to these characteristics and from the aspects of practicability and universal applicability,it proposes a solution to simplify LED illumination with driver based on CRD.In the end,this solution is adjusted with PF value.It overcomes the serious electromagnetic interference of switching power supply,the high cost of manufacture and some other disadvantages.The LED stroboscopic effect problem is greatly eliminated as well.At the same time,high conversion efficiency is ensured and the PF value is raised.The circuit is practical,easily manufactured and popularized with high commercial value.
