摘　　要：针对室内可见光灯源布局功率分布不平坦及通信质量差的问题,提出了一种对称米字型灯源布局方案。该方案通过构建与接收功率相关的目标函数,并融合Logistic混沌、反向策略、非线性函数以及自适应机制,在考虑一次反射的条件下,采用基于混沌逆初始化自适应权重哈里斯鹰优化算法(简称LRNA-HHO算法),实现了发光二极管(LED)位置及功率参数的最优设计。仿真结果表明:在5 m×5 m×3 m房间区域内,采用LRNA-HHO算法设计的灯源布局在功率分布上更均匀,接收功率方差为0.018 dBm,光照度均匀度达到0.925;信噪比范围为23.62~23.91 dB,通信质量得到明显改善。Symmetrical the meter-shaped lighting layout scheme is proposed to address the issues of uneven power distribution and poor communication quality in indoor visible light sources.This scheme involves creating an objective function related to the received power and integrates logistic chaos,reversal strategies,nonlinear functions,and adaptive mechanisms.Considering single-reflection conditions,it employs a chaotic reverse initialization adaptive weight Harris Hawk optimization algorithm(referred to as the LRNA-HHO algorithm)to achieve the optimal design of light emitting diode(LED)positions and power parameters.Simulation results show that the lighting layout designed using the LRNA-HHO algorithm distributes power more evenly within a 5 m×5 m×3 m room area,with a received power variance of 0.018 dBm and illumination uniformity reaching 0.925,the signal-to-noise ratio ranges from 23.62 to 23.91 dB,significantly improving communication quality.
