| 摘 要： | 新一代大功率白光LED光源具有很多优点,如节能、环保、寿命长等,但大功率LED的散热也是一个至关重要的问题。如果LED散热问题解决不好,LED灯具工作一段时间后就会输出光功率减小,芯片加速老化,工作寿命缩短。文章从LED散热问题着手,详细介绍了目前广泛商用的大功率LED器件结构及导热途径、所用散热基片的特点,以及LED所用的散热片设计和计算方法。另外介绍了一种大功率LED在散热片上不同位置温度变化的测试结果,并推导出用于计算LED器件散热的有效公式。

| Abstract: | Today,a new generation of LED light has prominent advantages such as energy saving,environmental protection and longer life expectancy.However,the heat that the power LED is a particularly important issue.If the LED cooling could not be solved,the output optical power should be decreased,the chip degeneration should be accelerated and the life expectancy should be shortened.It introduces the device structure and the heat conduction ways of the commercial power LED at present,the heater characteristic,and th... |
