高效率LED驱动电路的设计

Design of the High-efficiency LED Constant Current Drivers

恒流驱动是最佳的LED驱动方式,设计采用了市电220 V给LED灯供电的开关电源式恒流源,解决了降压、整流、变换效率高、较小的体积、较低的成本、还有安全隔离等一系列问题。经过实物电路的调试,设计基本上能实现上述要求,验证了设计方案的可行性。

Constant current driver is the best driving way to LED. The design directly uses the city electricity - 220 Vs to provide a constant current source of switch power supply type to LED light, which resolves a series of problems of voltage reduction, rectification, high-efficiency, smaller physical volume, lower cost of the transformation efficiency and the safety insulation. After the debugging with real object electric circuit, this design basically can carry out the above-mentioned request and the possibility of design project is verified.
