LED护栏灯在隧道照明中的应用研究

摘要

本文介绍的LED护栏灯是一种基于LED低位照明技术的新型灯具，具有能耗低、寿命长、易维护等特点，而且用于道路照明时可以很好地解决眩光问题。本文介绍了LED护栏灯的配光方式，并以四川乐自高速长山隧道为例，对比隧道照明使用高压钠灯、 LED吸顶灯、 LED护栏灯三种设计方案的综合效果和经济效益，结果显示， LED护栏灯无论是在照明效果、能耗、维护成本方面都明显优于目前隧道采用的高压钠灯和LED吸顶灯。%LED guardrail lamps are developed based on the LED low -location illumination technique , which have low energy consumption , long service life and easy maintenance .They can solve the glare problem well in road illumination .This paper illustrates the light distribution of the LED guardrail lamps and compares the effect and economic benefit of the applications of HPS , LED ceiling lamps and LED guardrail lamps in the lighting of Changshan tunnel of Sichuan Highway .The results show that LED guardrail lamps are obviously better than HPS and LED ceiling lamps on illumination effect , energy cost and maintenance cost .
