摘　　要：户外低位照明具有视线诱导性好、光污染小、光效利用率高以及维护安装成本低等优点,被广泛应用于城市景观和户外道路照明等领域。与传统公路隧道高位照明相比,若低位照明技术应用于公路隧道照明时,是否仍具有其独特优势有待验证,以及是否满足安全和舒适性等要求。因此,本文采用数值分析的方式,对公路隧道中间段进行线性布灯配置,并与点式低位照明和高位照明进行对比分析其照明质量。分析得出:传统间距点式布灯对于低位照明来说优势不显,光效利用率并不高,眩光负面影响不可忽略;而低位线性照明的单灯低光通量在一定程度上能降低眩光的负面影响,并且路面均匀度和隧道边界识别优势突出。Outdoor low-level lighting has advantages such as good visual guidance,low light pollution,high luminous efficacy,and low maintenance and installation costs,making it widely used in urban landscape and outdoor road lighting.Compared to traditional high-level lighting in highway tunnels,it remains to be verified whether low-level lighting technology retains its unique advantages when applied to highway tunnel lighting,as well as whether it meets safety and comfort requirements.Therefore,the author employs numerical analysis to configure linear lighting in the middle section of the highway tunnel,and compares its lighting quality with that of point-source low-level lighting and high-level lighting.The analysis concludes that traditional spaced point-source lighting shows limited advantages for low-level lighting,with low luminous efficacy and significant glare issues.In contrast,low-level linear lighting with low luminous flux per fixture can somewhat reduce the negative impact of GR glare,while also enhancing surface uniformity and tunnel boundary recognition.
