摘要

针对直下式LED平板灯厚度大、光源密度大的缺点,设计了一种带有圆锥台光学元件的超薄直下式LED平板灯,利用漫反射背板和反光圆锥台结构增加LED的混光距离,提高平板灯均匀度.应用划分单元的思想,以一个六角形光源为单元进行研究,采用Taguchi实验方法设计正交试验组并借助Tracepro软件仿真;考量六角形光源的圆锥台元件上下表面半径、厚度、距LED高度以及LED间距5个因子对该灯具均匀度和光效率的影响,并运用ANOVA理论分析出因子对品质的影响程度,进而优化灯具的各项结构参量,最终设计出一款厚度仅15 mm,均匀度达95.3%,光效率达92.97%的直下式LED平板灯.

Abstract

An ultra-thin direct-down LED panel model with tapered optical elements was proposed to cover the shortcomings of large thickness and light density of the direct-down LED panel light. The diffuse reflection backboard and the reflective cone structure in this model can increase the LED light mixing distance and improve light uniformity. Using the idea of dividing unit,a hexagonal light source is used as a unit to study in Taguchi method by designing orthogonal experimental group. With the Tracepro software simulation,the five factors influencing light uniformity and efficiency are taken into consideration,including the radius on upper and lower surfaces of the truncated cone element,thickness,height and LED spacing of the hexagonal light source. Apply ANOVA theory to analyze the impact of those factors on the quality,then optimize the structure parameters of the light. And ultimately,a direct-down LED panel light with the thickness of only 15 mm,the light uniformity up to 95.3% and the light efficiency up to 92.97%,are designed.
