摘要

根据LED的光强分布推导出侧光式背光源导光板平面上某点的照度公式,并得出导光板中散射网点的排布公式。主要通过对导光板散射网点形状的研究,找出最适合导光板的网点形状。以半球形网点形状为基础,根据在两个方向上耦合进导光板的光线经半球形网点反射后恰好输出的条件,得出顶角在90°~132.2°的圆锥体网点为最佳的形状。最后在达到一定的输出光通量均匀性的情况下,经过光学软件TracePro模拟仿真,比较不同顶角值圆锥体网点导光板的总输出光通量。实验结果与理论结果相一致。

Abstract

According to the light distribution of LED, we figure out the formula of a dot illuminance on the plane of the edge-lighting backlight light guide plate (LGP), and an arrangement formula of scattering dots in the LGP as well. The main purpose of this paper is, by studying the shape of the scattering dots in the LGP, to find out the scattering dots shape which is the most suitable for the LGP. Based on the hemispherical dots shape, according to principle that the light coupled into the LGP in two directions is reflected by the hemispherical scattering dots and just outputs from the LGP, it is obtained that the optimum shape of scattering netted dots is the cone whose apex angle between 90° and 132.2°. Under the condition of a certain uniformity of output light flux, by means of TracePro software simulation, the total output light flux is compared for the LGP with different apex angles of cone scattering dots. The experimental and theoretical results match well with each other.
