高压钠灯与LED灯在公路隧道中的应用对比分析

对于隧道照明系统节能,除合理选择设计参数、智能调光控制等措施外,科学选用电光源也是实现照明节能的重要手段。结合公路隧道照明功能需求及光源特点,探讨常用节能光源高压钠灯与新型节能光源LED灯在隧道内应用的差异性,并对2种照明系统进行经济效益对比分析,为今后国内公路隧道工程合理选用光源提供参考。

Comparative Research on Application of High-pressure Sodium Lamp and LED Lamp in Highway Tunnels

For energy conservation of tunnel lighting systems,scientific choice of electric light sources is also important means to realize lighting energy conservation except for measures including reasonable selection of design parameters and intelligent dimming control,etc.In combination with functional demands and features of light sources of lighting in highway tunnels,this paper probes into the differences between common energy saving light source-high-pressure sodium lamp and new energy saving light source LED tunnel lamp applied in tunnels and conducts comparative analysis for economic benefits of two lighting systems,providing a reference for rational choice of light sources in domestic highway tunnel projects in the future.
