This paper introduces the field study activities about the road and highway tunnel in Shanghai, Beijing and Nanjing which use the LED lighting. This paper shows and analyzes the application effects of tunnel construction and lighting engineering, points out the advantage of LED lighting over traditional lighting. However, this paper proposes some problems to solve. These views are hoped to play an important role in the application of LED lighting in the tunnel.%该文对采用LED照明的上海、北京及南京三地的公路及高速公路隧道的实地考察活动进行了介绍,文中涉及了隧道的工程建设、照明工程的实施及其应用效果,并对此进行了分析,指出了LED照明相对于传统照明方式所具有的优势,但也提出了目前存在,且亟待改进的问题。还望此次考察之见解能对LED照明在隧道中的应用推广起到抛砖引玉的作用。
