基于“按需照明”的隧道照明能效分析研究

Energy Efficiency Analysis of Tunnel Lighting Based on“On Demand Lighting”

隧道照明系统是影响行驶安全和舒适的重要因素,良好的照明环境是隧道运营安全的有力保障。然而隧道照明系统的电能消耗一般占隧道总电能消耗的70%以上,巨大的电费支出往往成为运营单位的重要负担。随着交通量的增加,隧道照明系统须进行亮度的提升,在提升亮度的同时必须考虑照明系统的智能化调控,以做到“按需照明”,避免过度照明造成的无效电能消耗。本文针对某隧道的照明系统改造升级方案,通过数值模拟预估了其实施后的亮度水平,基于“按需照明”的理念,提出了降低电能消耗的技术方案和路线。

The tunnel lighting system is an important factor that affects driving safety and comfort,and a good lighting environment is a powerful guarantee for the safety of tunnel operations.However,the electrical energy consumption of the tunnel lighting system generally accounts for more than 70%of the total electrical energy consumption of the tunnel,and huge electricity expenses often become an important burden for the operating unit.With the increase in traffic volume,the tunnel lighting system must increase the brightness.While increasing the brightness,the intelligent control of the lighting system must be considered to achieve"on-demand lighting"and avoid ineffective power consumption caused by excessive lighting.Aiming at the renovation and upgrading plan of a tunnel's lighting system,this paper estimates its brightness level after implementation through numerical simulation.Based on the concept of"on-demand lighting",technical solutions and routes to reduce power consumption are proposed.
