Frequently Asked Questions

LED tunnel light is a special LED lamp used for tunnel lighting to solve the “black hole effect” or “white hole effect” caused by the sudden change in brightness when the vehicle enters or exits the tunnel.

Certain special visual phenomena must be considered in tunnel lighting. In order to optimize the design of tunnel lighting, it is necessary to understand some basic visual problems. During the day, the driver will encounter the following visual problems when entering the tunnel: Just entering the tunnel, the brightness outside the tunnel during the day is much higher than that in the tunnel. If the tunnel is long enough, the driver will see a dark hole. This is the “black hole” phenomenon; if the tunnel is short, a “black frame” will appear in front of the driver. After entering the tunnel from the bright outside into a darker tunnel, the vision will have a certain adaptation time and then can see the situation inside the tunnel clearly. This phenomenon is called “adaptive hysteresis.” In the middle of the tunnel, because the exhaust gas discharged by the car accumulates to form smoke, the light of the car headlamp will be absorbed and scattered by the smoke, forming a light curtain and reducing the brightness contrast between the front obstacle and the background (road surface, wall), Which affects the visibility of obstacles and adversely affects visual function. There will be a very bright exit at the exit of the tunnel, which will produce a strong glare to the driver so that the road conditions are not clear, and car accidents are prone to occur. For this reason, tunnel lighting is usually divided into entrance lighting, interior lighting, and exit lighting. Among them, the requirements for entrance lighting are more stringent, requiring a gradual decrease in brightness similar to the outside world. Specifically, the brightness of the tunnel entrance lighting during the day is determined according to the brightness outside the tunnel, the speed of the vehicle, the field of view at the entrance, and the length of the tunnel.

This is determined by the special structure of the tunnel and the physiological structure of the human eye. Because the tunnel is a semi-enclosed construction, there is a significant brightness difference between the inside and outside. When a vehicle enters or departs a tunnel, the human eye must adjust to the change in time. In other words, adaption lag arises. Due to the sudden drop in brightness, people’s visual response is delayed when vehicles enter the cave during the day, creating a “black hole effect” that makes it difficult to distinguish the situation within the cave; when the vehicle exits the tunnel, a “white hole effect” is created, causing intense glare.

In order to avoid an excessive difference in light intensity between the inside and outside of the tunnel and short-term visual obstruction to human eyes, the LED lights at the entrance and exit of the tunnel must be dense so as to reduce the difference in light intensity between the outside and inside of the tunnel during the day and ensure the driver’s safety.

Normally, the LED lamps in the tunnel are often designed in two rows, which is also out of consideration for the driver’s driving safety. Generally speaking, the LED tunnel lights are divided into two rows with two lights, which are located on both sides, and the top lights are opposite to the ground, so that they can illuminate the space without reflection.
