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.
