大尺寸LED背光源的热分析
Thermal Analysis of Large Scale LED Back Light Unit
摘要
以119.4 cm(47 in)侧光式LED背光源为模型，采用有限元方法对其进行热分析，计算出不同情况下的温度场。由计算结果可知：采用铝材做背板，散热性能比电镀锌钢板(EGI)材料好20%以上。对LED背光源的温度场进行了实际测量，计算结果和实测温度相一致，证明所提出的分析方法是可行的。
Abstract
The temperature field of 119.4 cm(47 in) LED backlight unit was analyzed by finite element method. As a result, the efficiency of Al back cover is better than that of EGI one over 20%. Comparing the calculation result with the real temperature, the relative error is only 1.65%.The experimental results show that the temperature field analysis method for LED backlight unit is feasible.
