摘　　要：从隧道照明亮度均匀度出发,以《公路隧道照明设计细则》的评价标准为约束条件,利用逐点法优化建立了一种基于隧道结构参数的灯具配光模型。通过DIALUX光学软件构建仿真隧道场景,将隧道结构参数代入该灯具配光模型计算出适配的灯具配光曲线,并对设计灯具的照明性能进行了实验验证。结果表明,采用该模型设计的照明灯具,可以保证隧道环境的平均照度、平均亮度、亮度均匀度和纵向亮度均匀度均满足国家评价标准。此外,在实验中通过调节多项隧道参数(布灯方式、灯具安装仰角和安装间距),对照明质量进行对比分析,得出设计灯具在初始隧道参数下照明质量和节能性均最佳的结论,验证了隧道灯具配光模型的高效性,并证明了该模型在隧道灯具设计领域具有很好的应用推广价值。This study begins from the tunnel lighting’s brightness uniformity,which takes the evaluation standard of detailed rules for highway tunnel lighting design as the constraint condition,and a light distribution model of lamps based on tunnel structural parameters is created using the point by point approach.The simulation tunnel scene is constructed using DIALUX,the tunnel structure parameters are brought into the lamplight distribution model,and a suitable lamp light distribution curve is computed,the designed lamps’lighting performance is confirmed using experiments.The findings demonstrated that the lighting fixtures created with this model can guarantee the tunnel environment’s average illuminance,average brightness,brightness uniformity,and longitudinal brightness uniformity match the national evaluation standards.Furthermore,the lighting quality is compared and examined by adjusting numerous tunnel parameters in the experiment(light distribution mode,lamps’installation elevation,and installation spacing),and it is concluded that the designed lamps provide the best lighting quality and energy savings under the initial tunnel parameters.The efficiency of the tunnel lamps light distribution model is confirmed and demonstrates that the model has good application and popularization value in the tunnel lamp design field.
