基于Taguchi方法的曲面LED阵列照度问题研究
Study on Curved Surface LED Array Illumination Problem Based on Taguchi Method
摘要
为了分析曲面底板配光的LED阵列照明照度的影响因子,采用Taguchi实验方法设计实验,并运用TracePro软件进行仿真模拟,再通过ANOVA理论分析出因子对LED阵列品质的影响程度,优化曲面底板LED阵列的各项结构参数.结果表明: LED芯片数量对于照度均匀度及最大照度的影响最大,分别占有81.84%和91.58%的影响地位.进一步地,通过微调芯片与光轴的夹角可以得到更好的照度均匀度.以上研究结果为解决曲面底板照明的照度问题提供了理论依据.
Abstract
In order to analyze the control factors of LED array illumination on the curved surface plate,some experiments were designed by using Taguchi method and simulated via TracePro software.Then,ANOVA theory was integrated to evaluate the influence of the control factors on the illumination,so that the control factors could be optimized efficiently.The experiment results show that the number of LEDs is the main influence on both illuminance uniformity(81.84%) and maximum illumination(91.58%).Furthermore,the best combination of the control factors can be obtained by adjusting the angle between the LED chips and the optical axis.This paper provides a theoretical basis to solve the illumination problem of the curved surface lighting.
