大功率LED照明驱动匹配方式研究

The Study of Driver Matching that Applied in High-power LED Lighting

文章分析了大功率LED的原理和工作特性,LED的特性也决定了驱动电源的性能要求,LED照明适合恒流源驱动。然后具体分析了LED驱动的几种匹配方式,包括全部串联、全部并联、混联、交叉阵列和分布式恒流架构。最后指出,对于大功率LED照明来说,分布式恒流是未来驱动电源的发展方向。

This paper analyzed the principles and working characteristics of High-power LED.The characteristics of LED determine which power driver to use.LED lighting needs constant current driver.The article expounds several matching types of LED driver,including all in series,all in parallel,series-parallel connection,crossed connection and distributed constant current.For high-power LED lighting,the distributed constant current driver is the future direction of development.
