Abstract: Aiming at the lighting challenges of containers, such as enclosed narrow space and high reflectivity of inner walls, this paper conducts lighting simulation and scheme optimization based on the DIALux platform. Through 3D modeling, comparison of multiple schemes and analysis of key indicators, a lighting scheme that balances illuminance uniformity and glare control is determined. All indicators comply with relevant industrial lighting standards, which can provide practical references for the lighting design of similar enclosed spaces.
