Highway tunnel lighting is usually based on the current specification into the tunnel entrance, the transition section, an intermediate section and an outlet section design, wherein the transition section has two, respectively, before and after the mid-section design. The length of each segment and the illumination from the annual traffic safety requirements, the maximum illuminance on the cave outside the cave design is based on annual maximum brightness and maximum driving speed to determine the segments of the tunnel lighting power and lighting distribution density. Is very limited control to achieve automatic control of lighting, usually due to a wiring circuit limit line, can do Level 2-3 manual or automatic control, for such as weather, vehicle speed, traffic and other parameters just to give the maximum value in the design phase Consider the final length of each segment lighting and illumination also always be at a maximum state. For weather, vehicle speed, traffic volume and other parameters can not be changed from the macro to the entire tunnel lighting system can be adjusted to control an adaptive way. Therefore, this sense, the current tunnel lighting systems using traditional design and there are a lot of wasted energy issues.
