高均匀度超薄直下式LED平板灯混光元件的设计与研究

为了设计更好的LED平板灯光学结构, 解决现存的直下式LED平板灯厚度大, 光源密度大的缺点, 提出了两种兼具反射、投射作用的混光元件结构：椎台结构和半球型结构, 并将其应用于超薄直下式LED平板灯的设计, 以增加光线的耦合距离来提高出光均匀度.借助Tracepro软件研究两种不同结构混光元件应用于LED平板灯时的出光均匀度和光效率, 运用Taguchi方法设计实验进行研究.结果表明, 带有棱锥型结构元件的灯具均匀度达到95.42%, 光效率达到92.72%, 而带半球型结构元件灯具均匀度达到97.67%, 光效率达到92.65%, 其均匀度高于棱锥结构的原因是棱锥形状混光元件反射面的定向反射导致光线方向过于集中.

Abstract

In order to design better optical structure of LED panel light and solve the existing direct-down LED panel light′s shortcomings of large thickness and high light source density, this paper puts forward two mixed optical components including vertebral structure and half spherical structure that have both reflection and projectionand are applied to the design of ultra-thin direct-down LED panel light to increase the coupling distance of light to improve the light uniformity. The light uniformity and light efficiency are researched when two optical components with different structure are applied to LED panel light by Tracepro software, and further experiments were carried out by Taguchimethod. The results show that the light uniformity of the lamps with vertebral structure′s components is 95.42% andits energy efficiency is 92.72% while the light uniformity of the lamps with half spherical structure′s components is 97.67% and its energy efficiency is 92.65%, the reason why its light uniformity is higher than vertebral structure′s is that the optical component with vertebral structure results in too concentrated light direction due to the directional reflection of the reflecting surface.
