摘要
蓄能发光多功能涂料辅助隧道照明技术可有效提高隧道内的照明亮度,提高路面照明均匀度,改善隧道内视觉的舒适度,并且采用蓄能发光涂料具有长余辉的特性,充分的利用可以提升隧道照明效果,达到节能的目的。文章采用DIAlux数值模拟的方式,仅使用汽车灯光照明的方式,在隧道的周身喷涂不同高度的蓄能发光涂料,满足《JTGT D70/2-01-2014公路隧道照明设计细则》所规定的最低亮度0.2cd/m^2的距离。得到涂满蓄能发光涂料的情况下满足0.2cd/m^2的距离将达到45.5 m,涂4.45m高的蓄能发光涂料时可以满足40 km/h行车速度的隧道照明要求。结合已有的工程应用实例,通过二者叠加,将大大增加照明的效果。在涂满蓄能发光涂料的隧道内,仅使用汽车灯光照明,三分钟内满足0.2cd/m^2的距离超过65m。分别能满足60 km/h设计时速和40 km/h,3 km和2 km以内的应急照明需求。研究内容对隧道应急照明设计具有借鉴意义。
The multi-function energy storage luminescent coating assisted tunnel lighting technology can effectively improve the lighting brightness in the tunnel,improve the evenness of pavement lighting,and improve the visual comfort in the tunnel.Moreover,the use of energy storage luminescent coating has the characteristics of long afterglow,which can improve the lighting effect of tunnel and achieve the purpose of energy saving.In this paper,the DIAlux numerical simulation was adopted,and only car lighting was used.The whole body of the tunnel was sprayed with different heights of energy storage and luminescent coatings,which can meet the distance of the minimum brightness of 0.2 cd/m^2 stipulated in JTGT D70/2-01-2014 Guidelines for Design of Lighting of Highway Tunnels.The distance of 0.2 cd/m^2 can reach 45.5 m when tunnel is fully coated with energy storage luminescent coating,and 4.45 m high energy storage luminescent coating can meet the lighting requirements for 40 km/h driving speed in tunnel.Combined with the existing engineering application examples,the effect of lighting will be greatly increased by the superposition of the two conditions.In the tunnel covered with energy storage luminescent paint,and only car lights are used for lighting,the distance meeting requirement of 0.2 cd/m^2 is more than 65 m within three minutes.It can meet the emergency lighting requirements within 60 km/h design speed and 40 km/h,3 km and 2 km respectively.It provides reference for emergency lighting design of tunnel.
