| 英文摘要 | 随着人们对照明设备节能环保和耐用低价的要求逐步提高,lEd光源的研究与应用也日趋广泛。然而lEd光源并没有得到普遍应用,主要难题是成本高和驱动电路的不稳定。针对此问题,在研究lEd特性的基础上提出了高稳定性和低成本的lEd线性恒流驱动电路,且具有结构简单、效率高、体积小等特点。通过模拟电网的波动,测试了此电路在实际电网中的恒流特性,还测试了此电路的效率和lEd的结温,经实际电路测试,此驱动电路能很好地实现恒流控制,电路效率较高,且lEd的结温较低,使lEd的控制特性得到改善。; With increasing demands in energy-saving,durable and low-cost lighting equipments,the research and application on LED light soure is becoming widely spread.However,due to high costs and instability of its driver,LED source light has not been universally applied.Based on studying in LED characteristics,this article designed a linear constant current LED driver circuit of high stability and low-cost and so on.It has the characteristics of simple structure,high efficiency,little size.It is tested that this driver circuit can realize well control of constant current.The efficiency of this circuit is more higher,and the temperature of LED junction is more lower.In short,the LED control characteristic gets improvement. |
