Research on high-power LED lighting array distribution based on large area stitching optimization

为了实现在(4 m×6 m)目标面积内模拟适合座舱人机训练的光照均匀环境,提出一种面积拼接的大功率LED阵列设计方法。针对传统矩形和圆形阵列的照度分布不均匀问题,采用一种改进型的阵列分布,结合改进的粒子群算法进行优化排布。经仿真分析,改进型单模块阵列的照度均匀性为91.17%。由于安装误差的影响,实际测试光照均匀性为89%。单模块阵列拼接优化多模块LED阵列,仿真结果为照度均匀性85.83%,光能量利用率87.40%。研究结果显示,使用面积拼接方法设计的改进型多模块阵列更适合模拟大面积光照环境,具有高照度均匀性和高光能量利用率的特点,对实际应用具有重要的参考价值。

To achieve a uniform lighting environment suitable for cockpit man-machine training in the target area(4 m×6 m),a design method utilizing area splice of a high-power LED array was proposed.In order to address the issue of uneven illuminance distribution in traditional rectangular and circular arrays,the arrangement was optimized through the employment of an improved array distribution and an enhanced particle swarm optimization algorithm.A luminance uniformity of 91.17%was exhibited by the improved single-module array based on simulation analysis.Due to the influence of installation errors,the actual test light uniformity was measured at 89%.After the optimization of the multi-module LED array through splicing,an illumination uniformity of 85.83%and a light energy utilization of 87.40%were indicated by the simulation results.The improved multi-module array,designed using the area splicing method,is indicated to be more suitable for simulating large area lighting environments.The characteristics of high illuminance uniformity and a high light energy utilization rate are possessed by the multi-module array.These findings hold significant reference value for practical applications.
