考虑制造缺陷的大功率LED灯翅片散热性能研究

Study on the Heat Dissipation Performance of High Power LED Lamp With Manufacturing Defects

随着白炽灯逐渐退出历史舞台,人们对于新光源的需求越来越迫切。大功率LED灯因其显著的优点而被人们所重视,但是其散热问题不容小觑。利用CFD计算软件对LED散热系统进行非定常热耦合分析,通过对比有制造缺陷的大功率LED灯在不同工况下的温度分布及外部流场流线分布,进而分析制造缺陷对大功率LED灯翅片散热的影响。

With incandescent lamps gradually withdraw from the stage of history, the demand of people for new sources of light becomes more and more urgent. High power LED lamp is wildly used for its significant advantages, however, the heat dissipation problem can not be underestimated. This page made non thermal coupling analysis with the help of CFD calculation software of LED cooling system , through the contrast of a manufacturing defect of high power LED lights in different conditions of temperature distribution and external flow line distribution, and then analysis the impact of manufacturing defects of high power LED lamp radiating fins.
