摘　　要：针对紫外光净化系统应用提出了一种紫外发光二极管(LED)阵列模组的均匀照度优化设计方法。该方法首先基于单颗LED的光强度分布采用几何光学理论计算净化层接收面上的照度;再结合阵列模组与净化层的间距、净化层最小照度与最大照度之比、单颗LED发光角度等要求,采用二分法和TracePro仿真分别得到最佳LED阵列间距和照度分布模拟结果;最后,还进行了阵列模组均匀照度测量实验,用于验证仿真模拟结果的准确性。研究结果表明:提出的设计方法能够实现不同照度均匀性、结构、光源要求下的LED阵列排布优化设计,对紫外光净化系统设计和开发有重要指导意义。We propose an optimized uniform illumination design method for the ultraviolet(UV)light-emitting diode(LED)array module considering its application in UV light purification systems.First,the geometrical optics theory is used to evaluate the illumination of the purification layer receiving surface based on the luminescence intensity distribution in case of a single LED.Then,by combining the requirements of the spacing between the array module and purification layer,the ratio of the minimum and maximum illuminances of the purification layer,and illumination angle of a single LED,the optimal array spacing and simulation results of illuminance distributions are obtained by the dichotomy method along with the TracePro simulation.Finally,an uniform illumination measurement test has been designed for the array module to verify the accuracy of the simulation results.The research results demonstrate that the proposed method can realize an optimal design of the LED array module under different requirements with respect to the illumination uniformity,structure,and light source;furthermore,the proposed method exhibits important guiding significance for the design and development of UV light purification systems.
