摘要:
积分球内部的直插式灯座既不适用于铝基板式LED光源的安装,也不能满足功率型LED光源的散热要求. 针对这一问题,通过三维软件为积分球设计一种通用的外接灯座,利用ANSYS软件的热分析模块,对该灯座加载模拟的最大设计热载荷并进行热稳态仿真分析,以得到整个灯座的模拟温度场分布. 然后利用ANSYS软件的多目标驱动优化分析工具,对灯座模拟温度场中的最高温度点(区域)进行结构优化设计,以降低灯座的最高温度. 最后在实验条件下,调节程控直流电源,加载最大设计电功率,验证热稳态下整个灯座的实际温度分布,并与仿真进行比较. 结果表明,实验得到的灯座温度场分布与仿真得到的温度场分布十分接近,经优化后的灯座最高温度明显降低.
Abstract:
The internal direct-insert-type lamp holder of integrating sphere was not suited for the installment of aluminium substrate-type LED light source, and it was also not met the cooling requirement of the power LED light source. To solve this problem, an universal external lamp holder for integrating sphere was designed by 3D software, and the entire temperature distribution of this lamp holder was simulated by the thermal analysis module of ANSYS software, after loading the simulant maximal design load and making a thermal steady-state analysis. Then according to the highest temperature distribution points(areas), the structural optimization design of the lamp holder was made by the goal driven optimization tool of ANSYS software to reduce the maximal temperature of the lamp holder. Finally, the actual temperature distribution in the thermal steady-state was verified and the temperature distribution was compared with the simulation results, after loading the maximal design electric power by regulating the programmable direct current power source under experimental conditions. The results show that the temperature distribution of lamp holder obtained by experiment is very close to the temperature distribution obtained by the simulation, and the maximum temperature of the lamp holder is reduced significantly after optimization.
