半导体发光技术(简称LED)是近年来崛起的一种新型高科技节能技术。LED照明技术因其具有使用寿命长、高效节能、无热辐射(属于冷光源)等显著特点,已在城市亮化工程中得到普遍应用,但在环境恶劣(潮湿、灰尘)公路隧道中的应用技术问题,还有待进一步研究。随着人类资源越来越匮乏,
Semiconductor light-emitting technology (referred to as LED) is the rise of a new type of high-tech energy-saving technologies in recent years. LED lighting technology has been widely used in urban lighting project because of its long service life, high efficiency and energy saving, no heat radiation (belonging to cold light source), but its application in harsh and dusty road tunnels Technical issues, yet to be further studied. As human resources become scarcer,
