RESEARCH ON UNDERGROUND TUNNEL INTELLIGENT LIGHTING CONTROL TECHNOLOGY FOR ENERGY SAVING RAILWAY SYSTEM

Abstract

Today, the climate is rapidly changing worldwide due to overuse of energy, and along with low-carbon green growth, the study is focusing on the development of renewable energy. Especially in case of urban railroads, the stations are built underground, in which dependence rate of artificial lighting is very high in the energy consumption ratio compared to other facilities. In order to solve this, the researchers replaced the fluorescent lighting equipment that is constantly lit in the tunnel section with high-efficiency LED lighting that controls dimming in conjunction with vehicle position information and the railway signalling system.
