摘　　要：道路照明质量主要受灯具配光和布设参数的影响。现行规范对灯具距高比和宽高比的建议范围难以满足实际道路照明发展需求,且已有研究对路面横向光效的关注较少,尚未全面述及路面横纵向的空间亮度分布特征。针对上述问题,通过DIALux软件构建市政道路光环境仿真模型,分析了灯具横、纵向发光角、距高比S/H和宽高比W_(eff)/H等因素对路面光效的影响规律。结果表明,S/H和纵向发光角α主要影响路面纵向光效,随着S/H的增大和α的减小,路面平均亮度L_(av)、纵向均匀度U_(L)与总均匀度U_(0)均有所下降。W_(eff)/H和横向发光角β则主要影响路面横向光效,二者对L_(av)、U^(*)和U_(0)的影响与纵向类似。进一步建立可用于市政道路照明设计与灯具选型的路面空间光效预测模型,量化了现行规范对灯具距高比和宽高比适用范围的局限。为了满足现行规范对路面亮度均匀性的要求,城市主干路布设短、中、长配光灯具的S/H适用范围应由现行规范的≤3、≤4和不限制调整为≤1.5、≤2和≤4;并提出宽配光灯具适用的W_(eff)/H为单侧布设≤1.8、双侧布设≤3.5。The quality of road lighting is mainly affected by the light distribution and layout parameters of lamps.The recommended range of lamps’S/H and W_(eff)/H in current specification is difficult to meet the actual road lighting development needs,and the existing research pays less attention to the lateral light distribution on the pavement,and there is no comprehensive description of the spatial distribution characteristics of the light on the pavement from both the longitudinal and lateral perspectives.A light environment simulation model of municipal road was constructed by DIALux to analyze the influence rules of horizontal and vertical luminous beam angles,S/H and W_(eff)/H of the lamps on luminous efficiency for this problem.The results show that the main factors affecting the longitudinal lighting effect of pavement are S/H and the longitudinal beam angleαof lamps.With the increase of S/H and the decrease ofα,the average luminance L_(av),the longitudinal luminance uniformity U_(L) and the total luminance uniformity U_(0) all decrease.W_(eff)/H and the lateral beam angleβdirectly affect the lateral lighting effect of the pavement,and the effects on L_(av)、U^(*)and U_(0) are similar to those in the longitudinal direction.A pavement space lighting effect prediction model that can be used for municipal road lighting design and lamp selection is further constructed,and the limitations of the current specification on the application range of S/H and W_(eff)/H of lamps are quantified.In order to meet the requirements of“U_(L)≥0.7,U_(0)≥0.4”in the current specification,the S/H applicable to lamps belonging to the short,medium and long light distribution types should be adjusted from≤3,≤4 and unrestricted in the current specification to≤1.5,≤2 and≤4;and proposed that the W_(eff)/H suitable for lamps belonging to wide light distribution type should be unilaterally arranged≤1.8,and bilaterally arranged≤3.5,which provides a more comprehensive reference for road lighting design.
