摘要

基于Light Tools光学分析软件分析了光在球形微结构扩散板和圆锥及金字塔两种非球形微结构扩散板内的传输过程

比较了球形微结构扩散板和非球形微结构扩散板的均匀度和透光率;进一步分析了金字塔非球形微结构的顶角

和切削量

对扩散板均匀度和透光率的影响。结果表明

金字塔非球形微结构扩散板的均匀度高于圆锥非球形微结构和球形微结构两种扩散板的均匀度

透光率介于圆锥非球形微结构扩散板和球形微结构扩散板之间。金字塔非球形微结构顶角

越大

透光率越高

当

=100°时

扩散板的综合光学性能最好

透光率达82.1%

均匀度达82.4%;切削量

越大

透光率越大

均匀度先增大后减小

当

=0.04 mm

扩散板的综合光学性能最好

透光率为84.2%

均匀度为86.2%。

Abstract

The transmission process of light in micro-sphere structure

micro-structure and micro-pyramid structure were analyzed. The transmittance and uniformity of micro-sphere structure

micro-cone structure and micro-pyramid structure were compared based on Light Tools software. At last

the effect of vertex angle

and cutting quantity

of micro-pyramid structure on uniformity and transmittance of diffuser were simulated. The result shows that the uniformity of micro-pyramid structure is the best while the transmittance is worse than micro-sphere structure. The transmittance becomes higher when the vertex angle

becomes higher. The transmittance is 82.1% and the uniformity is 82.4% when

=100°.The transmittance becomes higher when the cutting quantity

becomes higher while the uniformity increases first and decreases latter. The transmittance is 84.2% and the uniformity is 86.2% when

=0.04 mm.
