LED Tunnel Lights Used In Tunnel Lighting Should Pay Attention To What Issues?
Oct 27, 2017

The tunnel is the main structure of the mountain expressway, because of its special structure, the tunnel can not be direct sunlight, in order to solve the vehicle into or out of the tunnel when the brightness of the sudden changes in visual effects of "black hole effect" or "white hole effect" Need long-term lighting. Commonly used tunnel lighting is LED tunnel lights, the application of tunnel lighting should pay attention to the following questions:

1, glare control. In tunnel lighting, the glare should be kept to a minimum to ensure that the driver has enough visibility to travel. Generally in the tunnel lighting, the use of high-brightness LED as the light source, with light uniformity, the light soft and comfortable, to avoid causing uncomfortable glare phenomenon to ensure traffic safety.

2, lighting uniformity. LED tunnel lights are used in tunnel lighting to require uniform illumination. In the tunnel within 2m below the wall and the road surface minimum brightness and average brightness ratio, that is, uniformity. Uniform illumination helps the driver understand the road condition and avoid traffic accidents.

3, eliminate the "flashing effect". The main reason for the "flicker effect" is due to improper arrangement of fixtures, resulting in periodic changes in brightness and brightness, causing discomfort in the driver's line of sight. Therefore, in the installation of LED tunnel lights should pay attention to a reasonable layout, the effective planning of the distance between the Light and the Light, to avoid "flashing effect."

4, emergency lighting. In addition to conventional LED lighting tunnel, the emergency lighting is essential. In the tunnel, in case of emergency, emergency LED lighting in a very short event to provide the right amount of lighting, so that the driver to avoid accidents. Which also includes LED emergency instructions to ensure that the incident in order to ensure the safety of vehicles through the tunnel.

5, the tunnel partition. In the long tunnel lighting design, LED tunnel lights should be based on different sections of the tunnel to set up different lighting design, such as tunnel entrance and exit section of the illumination should be higher than the middle section and transition section, to the driver has been adapted from the tunnel to the tunnel Caused by the discomfort, but also to protect the tunnel lighting economy and practicality.
