Optimizing LED Array Irradiance Uniformity with a Particle Swarm Optimization-Based Scheme: Application in a Parallel Photoreacto

- Abstract: This study proposes a particle swarm optimization (PSO)-based method for enhancing the irradiance uniformity of LEDarrays in parallel photoreactors. We construct a spatial irradiance model, validating its accuracy with near-field opticaltest data and optical simulation results. An evaluation function for irradiance uniformity guides the iterative optimizationof the LED arrangement, taking into consideration practical constraints such as chip size, heat dissipation, and circuitboard wiring. The optimized LED array demonstrated a significant improvement in irradiance uniformity, increasingfrom 75.27% to 95.61%. This showcases the feasibility and effectiveness of our PSO-based method for practicalapplications in optimizing LED arrays.
