LED light becomes very popular in the lighting application, and there are kinds of driver circuit designs for now. Some LED driver circuit designs based on the CRD device for different LED light solutions were presented, which not only ensured the performance, but also simplified the design and reduced the cost of LED driver circuit.%LED照明是当前照明市场的热点趋势,对于其驱动电路设计方案层出不穷.根据恒流二极管的特性,针对LED照明中的小功率和大功率LED的不同特性,分别给出了驱动电路设计.保证LED驱动电路性能的同时大大简化了其驱动电路设计,降低了驱动电路的成本.
