Apron floodlight system(AFS)is vital for green airport development and energy saving,while the lack of detailed analysis of the apron floodlighting environment limits the strategy optimization of lighting energy saving.In this re-gard,an illuminance simulation model of combined aircraft stands is established using DIALux evo platform,a zoning lighting evaluation index based on apron operation function is proposed,and parameter impact analysis is carried out for both front and corner combined aircraft stands.Research results indicate that dual side high mast is necessary for the basic illuminance requirement of C-class aircraft stand,and the shading effect of aircraft and corridor bridge on light cannot be ignored.As for the corner combined aircraft stands,due to the large lighting range,it is necessary to control the vertical pitch angle projection direction of the lighting fixtures,and when the vertical pitch angle is greater than 45°,it is easy to cause glare indicators exceeding the limit,which is not con-ducive to ensure cockpit safety and cabin comfort.By integrating with neural network algorithm,the optimization process of high mast lighting parameters can be further improved.
