基于高斯模型的侧入式平板灯优化设计

Optimum Design of Lateral Flat Lamp Based on Gauss Model

为了提高侧入式平板灯亮度和均匀度,利用高斯分布函数的钟型曲线与光强分布为反相的特点,采用基于高斯模型优化网点分布的方法进行网点半径及间距设计;利用光损函数对LED灯珠进行排列,利用TracePro对光强幅度图进行分析,完成了圆形侧入式平板灯设计实验。实验结果表明,采用高斯模型优化的网点分布方法可使平均亮度达5 452 cd/m 2,均匀度提升至90%,优化后的模型表现出良好的性能优势,可以进行实际应用。

In order to improve the brightness and uniformity of lateral flat lamp,the bell curve of Gauss distribution function and the light intensity distribution were inverse.The radius and spacing of the dots were designed by optimizing the distribution of the dots based on Gauss model.The LED beads were arranged by using the light loss function,and the intensity magnitude map was analyzed by TracePro.The simulation experiment of circular flat lamp design was completed.The experimental results show that the average brightness can reach 5 452 cd/m 2 and the uniformity can be improved to 90%by using the optimized Gaussian model.The optimized model has good performance advantages and can be applied in practice.
