新型照明节电设备在高速公路隧道中的应用

大量调查数据显示,山区高速公路隧道照明灯具所承受的电压普遍高于正常供电电压。山区高速公路隧道照明系统长期在过压状态下运行,不仅会大幅增加能耗,还将导致灯具使用寿命远远低于额定值。基于理论分析和室内试验,对新型节电设备用于公路隧道照明系统的可行性进行分析,并针对实际工程案例给出具体的照明节能设计方案。应用智能照明节电设备可产生较好的经济、社会和生态效益,可在行业内推广应用。

Application of New Lighting and Power Saving Equipments in Expressway Tunnels

A great number of survey data show that the power supply for the lighting fixtures in expressway tunnels in mountainous area generally has a higher voltage than normal power supply.Over-voltage operation of lighting systems in expressway tunnels in mountainous area for long time will not only increase energy consumption greatly,but also lead to much lower service life of fixtures than the rated value.Based on theoretical analysis and indoor test,this paper analyzes feasibility of new power saving equipments used in lighting systems of expressway tunnels and offers specific lighting energy-saving design schemes in allusion of practical project cases.Application of intelligent lighting power saving equipments can produce good economic,social and ecological benefits and can be popularized in industry.
