| Abstract: | 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. |
