LED
Tunnel Lights
have become a new type of lighting fixture developed in recent years due to their long lifespan, low energy consumption, high luminous efficiency, and controllable light distribution. They are commonly found in road tunnel lighting. Due to the unique nature of tunnel lighting, the arrangement of
LED
tunnel lights differs from conventional fixtures, but many drivers and users may have the following questions:
Why are there more
LED
tunnel lights at the tunnel entrance and exit?
This is determined by the special structure of tunnels and the physiological characteristics of the human eye. Because a tunnel is a semi-enclosed structure, there is a significant difference in brightness inside and outside the tunnel. When a vehicle enters or exits the tunnel, the human eye requires an adaptation period, resulting in an “adaptation lag effect.” When a vehicle enters the tunnel during the day and experiences a sudden drop in brightness, the visual response lags, creating a “black hole effect,” making it difficult to discern the situation inside the tunnel. Conversely, when a vehicle exits the tunnel, the “white hole effect” can create intense glare.
To avoid excessive differences in illumination intensity between the inside and outside of the tunnel, which can cause temporary visual impairments for the human eye, it is necessary to use
LED
lights more densely at the tunnel entrance and exit, in order to reduce the contrast in light intensity between the outside and inside during the day and ensure the safety of drivers.
The reason for arranging
LED
tunnel lights in two rows inside the tunnel
Typically,
LED
tunnel lights are designed with two rows as a consideration for driver safety. Generally speaking, they are arranged in two rows, creating two beams of light positioned on either side, with top lights aimed at each other and not directed at the ground. This design illuminates the space without causing reflections. The following image shows a comparison of the illumination effect between single-row ordinary lighting fixtures and double-row
LED
tunnel lights.
