At the same time, the design of tunnel lighting system and maintenance becomes more and more important. Good tunnel lighting design is to consider the factors related to the length of the tunnel, and the type of the road, road shape, interior, sidewalk, design speed, traffic volume and vehicle types such as, tunnel of color of light source, lamps and lanterns, lamp arrangement, reasonable induction lighting design and lighting control design, to meet the visual information gathering of drivers traffic safety, improve the driving safety and comfort, and eventually reach to reduce operating costs. This paper first introduces the background and significance of this study, domestic and foreign research status and development trends, and point out how the content of this research is determined. Then the brightness of the tunnel lighting circuit are detailed calculation and analysis, control and the manual control, at the time to carry out timing and, according to the brightness of inside and outside the hole value automatic control lighting circuit of full automatic control three way, as well as their advantages and disadvantages are analyzed and compared. At the same time, the main detailed analysis of manual control and segmenta
