Research of Illumination Uniformity for LED Arrays Based on PSO Algorithm
it is of great significance to apply LED arrays to enhance the brightness and enlarge the luminous area to improve the uniformity of illuminace. Different from traditional analytical calculation methods
particle swarm optimization algorithm was proposed to optimize the structure of LED arrays to achieve a good uniform illuminace distribution on the target plane in this paper. Firstly
formulae of illuminance distribution on target plane illuminated by LED arrays were obtained
and then an evaluation function was constructed to measure the uniformity of illuminance distribution. Matlab software was used to calculate the initial structure parameters. Finally
Tracepro optical software was adopted to give an imitation and simulation. The simulation results show that the LED arrays can produce highly uniform illuminace distribution. It indicates that our method is simple and can optimize the LED automatically by computer program.
