With the increasing of tunnel projects, tunnel construction plays an increasingly important role in modern transportation. The tunnel is a closed space, in order to ensure the continuity of travel and the safety of the driver, even indoor lighting requires artificial lighting for the whole day.
Tunnel lighting is an indispensable part of tunnel construction. The light source of led tunnel lights should meet the requirements of light efficiency, luminous flux, lifetime, color temp and color rendering in a specific tunnel environmentl. At the same time, ensuring good visibility in the smoke formed by automobile emissions. The lighting effect of led tunnel lights must be achieved by relying on a reliable light source.
Tunnel is different from the normal roads, it has remarkable speciality. The safety is especially important in the lighting system.
When making the tunnel lighting plan, it is necessary to consider the human habits and dark habits, paying attention to the lighting transition. In order to satisfy the habitual needs for driver's eyes, a dark transitional illumination is required at the entrance of tunnel, ensuring a certain vision requirement. As the short habits at the exit of the tunnel, it is usually within 1s, so no other disposal is possible.

There are usually several special visual problems in tunnels:
(1) Before entering the tunnel (daytime).
(2) After entering the tunnel (daytime).
(3) Exit of the tunnel.
Tunnel lighting is usually divided into five sections: entrance section, adapting section, transition section, base section and exit section.
Each section has different effects:
(1) Entrance section: Eliminate the appearance of “black hole”, so that the driver can identify obstacles at the tunnel entrance; take the daytime as an example, assuming the ambient brightness of the tunnel opening is 4000 cd/m2 and the speed is 80KM/H, the introduction of the minimum demand is satisfactory. The length and brightness of the segments are 40 meters and 80 cd/m2, respectively.
(2) Adapting section: After entering the tunnel, the driver can quickly get used to and eliminate the appearance of “black hole”; according to the above conditions, the length and brightness of the customary section are 40 meters and 80~46cd/m2 respectively.
(3) Transition section: The driver is gradually accustomed to the internal lighting of the tunnel; according to the above conditions, the length and brightness of the transition section are 40 meters and 40~4.5cd/m respectively.
(4) Base section: normal lighting inside the tunnel.
(5) Exit section: During the day, the driver can gradually get used to the glare at the exit and eliminate the appearance of “white hole”. At night, the driver can see the line of the external road and the obstacles on the road in the cave. To eliminate the "black hole" appearance at the exit, it is common practice to use street lights outside the cave as continuous illumination.
During the day, the illumination level of the exit section of the tunnel should be higher than the entrance section, and should be higher than the normal illumination level in the tunnel; at night, on the contrary, it should be lower than the normal illumination level in the tunnel. When the street lighting is used, the brightness of the road surface in the tunnel shall not be less than twice the brightness value of the open air.
