Thermal analysis and test for convection-cooled LED lamp

  • 摘要: 对某LED灯开展了空气导流技术的散热设计,进行了有、无空气导流散热条件下的仿真分析,针对热分析模型进行反复修正迭代,得到了准确的仿真结果。仿真分析与试验结果表明,在有空气导流散热的情况下,LED灯的结温较无空气导流散热时降低约8℃,LED灯的使用寿命可延长2 000 h。进一步研究发现,基板下表面的发射率、接触热阻以及LED与对流孔之间的距离等因素对LED灯的散热均有影响,最终对各个影响因素进行灵敏度分析,给出了降低结温的几点建议。
    Abstract: Thermal design of air convection for an LED lamp was carried out. The simulations for the lamp with or without air convection were studied. In order to ensure the accuracy of simulation result, the thermal analysis model was modified repeatedly. The simulation and test results show that the junction temperature of the LED lamp reduces by about 8℃ with air diversion cooling, the lifetime of the LED lamp can extend by 2 000 hours. Further study shows that many factors affect the heat radiation apparently, such as the emissivity of base plate subsurface, the thermal contact resistance, and the distance between convection hole and LED. Sensitivity analysis for each factor was carried out, and some advices on how to further reduce the junction temperature of the LED lamp were put forward.
