我国公路隧道近年来迅速发展,同时隧道照明的投入和维护费用等高额的运营成本也制约着公路隧道的发展。本文结合临合高速公路隧道的应用实例,分析研究了LED灯具照明的优点,并对隧道常用照明灯具高压钠灯和新兴的LED照明灯具进行了比较分析,表明LED灯是一种高效的、节能的绿色照明灯具,具有良好的经济效益和社会效益,有着广阔的应用前景。 China’s highway tunnels developed rapidly in recent years. At the same time, high operating costs such as tunnel lighting investment and maintenance costs also restrict the development of highway tunnels. Based on the application examples of Linhe Freeway Tunnel, this paper analyzes the advantages of LED lighting and compares the high-pressure sodium lamp and emerging LED lighting lamps commonly used in tunnels. It shows that LED lamp is an efficient and energy-saving Green lighting, with good economic and social benefits, has a broad application prospects.
