摘　　要：比较了我国产品、应用、设计标准采用的几种常规道路照明灯具配光分类方法;以某款LED路灯为例,依据光强数据计算9项指标,判断其配光类型及适用范围,并用DIALux evo做道路样本模拟,计算评估了照明质量合规性。结论包括:配光分类方法不仅要考虑灯具的截光性能,还应考虑光束宽度(角);纵横配光类型间关联定义的合理性有待验证;目前国际上推荐基于IES室外灯具分类系统LCS对道路照明灯具进行BUG(Backlight, Uplight and Glare)分类,这是从眩光及干扰光限制角度进行的完善,而溢散光分类是对BUG分类的合并与简化。从产品角度,为了达到光度性能整体的平衡,必须在灯具配光类型各指标间进行折中,从而为不同类型的道路提供有针对性的产品;从应用角度,适当简化的配光类型较配光曲线和光强表更易理解和便于选型,建议生产商标称灯具的配光类型,推荐量化的适用范围以及适用的道路类型。The luminaire light distribution classification system for conventional road lighting used in the national product, application and design standards were summarized and compared. Taking a LED road luminaire as an example, 9 indicators were calculated based on its luminous intensity data, the type of light distribution and the scope of application were determined, and the road sample simulation was carried out by DIALux evo to verify the optical suitability. The conclusions are as follows: The beam width(angle) should be considered in the system besides cutoff;The rationality of association between the definition of vertical and lateral light distributions should be further discussed;At present, it is recommended internationally to establish a BUG rating for a road lighting luminaire to assess and classify its glare, obtrusive light and sky glow using the IES luminaire classification system(LCS)for outdoor luminaires. SP is the combination and simplification of BUG(Backlight, Uplight and Glare) rating. Design compromises between the indicators of light distribution groups become necessary in order to achieve balanced performance, for providing targeted products for different types of roads. From the perspective of application, the appropriately simplified light distribution is easier to understand and facilitate the luminaire selection than the distribution curve and I Table. Therefore it is suggested that the manufacturers should label the groups of light distribution for luminaires, the recommended quantified range and road type.
