1. Glare control. In tunnel lighting, glare should be controlled to a minimum to ensure sufficient visibility for the driver while driving. Generally, in tunnel lighting, high-brightness LEDs are often used as the light source, with uniform light distribution, soft and comfortable light, avoiding uncomfortable glare, and ensuring driving safety.
2. Illumination uniformity. LED tunnel lights are used in tunnel lighting and require uniform illumination. The ratio of the minimum brightness to the average brightness of the wall and road surface below 2m in the tunnel is the uniformity. Uniform illumination helps drivers see the road conditions clearly and avoid traffic accidents.
3. Eliminate the "flicker effect". The main reason for the "flicker effect" is due to the improper arrangement of lamps and lanterns, which produces alternating light and dark brightness cycles, causing discomfort in the driver's line of sight. Therefore, when installing LED tunnel lights, you should pay attention to the reasonable layout, effectively plan the distance between the lights and avoid the "flicker effect".
4. Emergency lighting. In addition to conventional LED lighting in tunnels, emergency lighting is essential. In the tunnel, emergency LED lighting can provide adequate lighting in a very short event, so that drivers can avoid accidents. It also includes LED emergency instructions to ensure that vehicles pass the tunnel in an orderly and safe manner in an emergency.
5. Tunnel partition. In the lighting design of long tunnels, LED tunnel lights should be set up with different lighting designs according to different areas of the tunnel. For example, the brightness of the lighting at the entrance and exit of the tunnel should be higher than that of the middle and transition sections, so that the driver has adapted to travel from the tunnel to the tunnel. The discomfort caused by the interior also guarantees the economy and practicality of tunnel lighting.
