【摘要】 传统的隧道照明设计采用明视觉标准,但隧道内有些区段的照明属于中间视觉范畴。采用照明设计软件DIALux设计了隧道模型,建立了LED照明系统,对属于中间视觉范畴的隧道中间段的照明进行了仿真试验。试验结果表明,在路面亮度要求相同的情况下,采用明视觉标准计算的照度和照度均匀度,结果偏小,均小于采用中间视觉S模型的计算结果,造成能耗偏高和照明视觉上的差异,路面亮度越低,视觉差异越大。更多还原

【Abstract】 Photopic vision standard was adopted in traditional design of tunnel lighting,but the lighting of some tunnel zones was in category of mesopic vision.A tunnel model is firstly designed with lighting software-DIAlux and a lighting system with LED is established in the tunnel model.Then a simulation test is conducted on the lighting of mesopic vision in tunnel interior zone.The test results show that the road surface illuminance and road surface illuminance uniformity calculated by photopic vision standard are less than those calculated by mesopic vision S-model under the same condition of road surface luminance requirement,which causes more energy consumption and lighting vision difference.The less the road surface luminance is,the more significant the vision difference is.更多还原
