恒流驱动和提 高LED的光学效率是LED 应用设计的两个关键问题，本文首先介绍大功率LED的应用及其恒流驱动方案的选择指南，然后以美国国家半导体(NS)的产品为例，重点讨论如何巧妙应用 LED恒流驱动电路的采样电阻提高大功率LED的效率，并给出大功率LED驱动器设计与散热设计的注意事项。-LED constant current drive and to improve the optical efficiency of LED application design of two key issues, this paper describes the application of high-power LED constant current driver and the choice of the program guide, and then the United States National Semiconductor (NS) products, for example, focus on how skillful application of LED constant current driver circuit of the sampling resistor to improve the efficiency of high-power LED, and gives high-power LED driver design and thermal design considerations.

说明：  An Android weather project source code, using the API provided by Baidu, has the basic functions of weather query, city settings, Short Message Sharing weather, the interface is refreshing, but now because of Baidu key failure, can not update the weather. The code has more detailed comments. Code volume is not large, interested friends can check it by themselves.
