摘　　要： 作为LED灯具的核心部件,驱动电源直接影响LED灯具的性能与寿命。介绍了以电阻限流电路、线性调节器、开关调节器来做主电路的LED驱动电源,分析了三种电路的优缺点,指出开关调节器因具有精确自调控能力、高效率、高稳定性等优点,是目前大功率LED驱动电路的最佳选择。着重概括了开关调节器的研究现状。 As one of the core components of LED lamps, LED driving power directly affects the performance and life of LED lamps. In this paper, three kinds LED driving power circuits, i. e. , the resistance current limiting circuit, linear regulator, switching regulator, were introduced respectively. The characters of these circuits were analyzed. The switch controller is the optimum choice for high-power LED driving power, because of its advantages of accurate self-control ability, high efficiency, and high stability. Furthermore, the development of switching regulator was outlined emphatically.
