摘要
为了解决传统直下式发光二极管(LED)平板灯厚度大、均匀度较低的缺点,设计一种带半圆柱微透镜的超薄平板灯.该透镜上半部分是竖放的圆柱,下半部分是横放的半圆柱阵列.以一个正六棱柱作为单元模块,通过Tracepro软件及Taguchi实验法进行模拟仿真,对带半圆柱微透镜的半圆柱半径、圆柱厚度、透镜半径及透镜距LED的高度进行优化.结果表明:当半圆柱半径为0.2 mm,透镜半径为1.5 mm,透镜距LED高度为2.5 mm,圆柱厚度为0.5 mm时,其显示效果最好,并设计出一款厚度为15 mm,照度均匀度为95.53%,光效率为95.99%的超薄直下式LED平板灯,该平板灯符合现代超薄、节能的发展要求.
In order to solve the shortcomings of the traditional straight-down light emitting diode(LED)plate lamp with large thickness and low uniformity,an ultra-thin plate lamp with a semi-cylindrical microlens was designed.The upper part of the lens is an vertically placed cylinder and the lower part is a horizontally placed semi-cylindrical array.Taking a regular six-prism as the unit module,the simulation was carried out by Tracepro software and Taguchi experimental method,and the half-cylinder radius,cylindrical thickness,lens radius and lens distance LED height with half-cylinder microlens were optimized.The results show that:when the half-cylinder radius is 0.2 mm,the lens radius is 1.5 mm,the lens distance from the LED height is 2.5 mm,the cylindrical thickness is 0.5 mm,the display effect is the best,meanwhile design a thickness of 15 mm,illumination uniformity of 95.53%,light efficiency of 95.99%ultra-thin straight-down LED plate lamp,this panel lamp meet the requirement with the modern ultra-thin,energy-saving development.
