| Abstract |
As we know, topography of korea is composed of many mountains. Also, the volume of traffic is increasing more and more nowadays. So, many tunnels are being constructed to reduce cost of transport and time. Thus, tunnel illumination was considered as the most important thing to make safe traffic conditions. In the past, we installed luminaires on the wall in tunnel, but currently we are installing those on the ceiling. Wherever luminaires are installed on the ceiling, the electric designer may not have known the proper point to install luminaires. Therefore, we researched this project to resolve above problems with abundant experience and accurate data through simulation(Lightscape program). As a result of research, mounting luminaires on the ceiling are better than wall because uniformity is more regular and utilization factor is also higher and then brightness is adequate as well , whereby installation on the ceiling is economical. Therefore, it is suitable that luminaires are installed on the ceiling in tunnel than wall. |
