摘要
详细论述了导光板的工作原理以及导光板网点设计的理论。利用几何光学的反射、折射、散射等理论,推导出了非均匀网点分布公式,设计了一款大尺寸LED双侧边缘背光的导光板。利用光学模拟软件建立导光板模型,并进行了调试仿真。在充分考虑成本和可能性的前提下使得均光度接近80%,达到了广告灯箱对均光效果的要求。
The working principle of light guide and the light guide network design theory have been discussed.The formula for the distribution of non-uniform network is derived by using reflection,refraction,scattering theory of geometrical optics,and a large-size bilateral-edge LED backing guide plate is designed.The light guide plate model is debuged and simulated by using optical simulation software.And taking full account of the cost and feasibility,the result of uniformity is very close to 80%,which fully meets the need of advertising light boxes.
