With the rapid development of China's road traffic construction, the scale and number of highway tunnel construction is also increasing, so in the tunnel lighting combined with advanced control methods, the use of high luminous efficiency, good stability, long life of the new generation of light sources will become a demand and trend LED tunnel light under the tunnel lighting is special, then LED tunnel light under the tunnel lighting special features, so LED tunnel light What is the special nature of tunnel lighting? Next, let's take a look at it.


This is the content list:

  • LED tunnel light tunnel lighting is different from ordinary road lighting

  • Highway tunnel lighting has its characteristics


LED tunnel light tunnel lighting is different from ordinary road lighting

LED tunnel light is different from ordinary road lighting because its all-weather 24 hours must be lit, daytime LED tunnel light lighting intensity than the night lighting intensity is stronger, you can imagine the LED tunnel light tunnel power costs become an important part of the operating costs. Plus LED tunnel light tunnel lighting is different from the general road lighting, there are LED tunnel light obvious special features, including the human adaptability to light and dark, light and dark transition space and lighting, etc. These are reflected in the design of LED tunnel light tunnel lighting, but also in the safety of users have an inseparable relationship. LED tunnel light tunnel lighting is usually divided into entrance lighting, interior lighting, and exit lighting. Among them, LED tunnel light entrance lighting requirements are very strict, requiring a gradual reduction in brightness from similar to the outside world. Specifically, the daytime LED tunnel light tunnel entrance lighting brightness is to be determined according to the brightness of the tunnel outside, the speed of traffic, the entrance field of view, and the length of the tunnel. The International Illuminating Institute (CIE) divided the tunnel entrance lighting into (from the tunnel entrance) threshold section and transition section. The threshold section is to eliminate the "black hole" phenomenon, so that drivers can identify obstacles in the tunnel entrance based on LED tunnel light, the tunnel transition section lighting is to avoid the threshold section LED tunnel light lighting and the interior of the basic lighting between the strong change and set, its lighting level further gradually decreased. And LED tunnel light tunnel lighting standards go further to the tunnel entrance lighting into the introduction section, adaptation section, transition section. The interior section is the area of the tunnel away from the influence of external natural lighting, the driver's vision is only affected by the LED tunnel light tunnel lighting. The internal section is characterized by a uniform illumination level throughout the LED tunnel light section. Because the LED tunnel light lighting level in this section does not need to change at all, so in this section only LED tunnel light provides the appropriate brightness level, the specific value is determined by the traffic flow and vehicle hourly speed. The distribution and brightness of the entrance, transition, interior, and exit sections of the tunnel.


      Highway tunnel lighting has its characteristics

Highway LED tunnel light has its characteristics, it is not the same as ordinary road lighting. In the design of the following points need to be considered to pay attention.

1. LED tunnel light road surface should have a certain level of brightness.

2. LED tunnel light tunnel walls should have a certain level of brightness.

3. LED tunnel light by the design speed, traffic volume, route alignment, and many other influencing factors.

4. From the safety and comfort of driving and other aspects of a comprehensive determination of LED tunnel light lighting level.

5. Human visual adaptability, especially the tunnel entrance section, exit section, and other places.

6. The tunnel also needs LED tunnel light lighting during the day, and LED tunnel light lighting problems during the day are more complex than at night.
