Series E led tunnel light for tunnel lighting and Series F led street light for lighting Tunnel entrance road in Hangzhou of China

The tunnel lighting project in Hangzhou of China, completed in 2013, used the discontinued E series tunnel light, E model tunnel light using the first modular design, module replacement is very convenient, the lamp beads used Bridgelux LEDs, due to LED technology updates, with the H and HB series floodlights and tunnel lights launched in 2014, E series underground tunnel light due to the cost and function can not meet market demand, and eventually discontinued, but up to now, this batch of tunnel lights are still in use, the failure rate is very low, customer feedback is very good.

As a professional LED lighting manufacturer, we have been committed to the innovation and development of lighting fixtures. Due to the discontinuation of E-type tunnel lighting and F-type roadway lighting fixture, we subsequently introduced high-efficiency tunnel lighting and underpass LED lights. H, HB, and ZOOM series LED tunnel lights for sale.

    What are tunnel lights’ “white holes” and “black holes”? People go through the tunnel, and the visual light fatigue is the same as if you were in a strong light from the tunnel, so you can’t see it. A “black hole” is one of these, whereas a “white hole” is the polar opposite. Because you are on the tunnel’s dark side, you can only see a dazzling light. The end is not in sight. Tunnel lights may help with these two circumstances, which are prone to traffic accidents.

    The tunnel’s unique structure, as well as the physiological structure of the human eye, dictate this. The brightness difference between the inside and outside of the tunnel is significant since it is a semi-enclosed construction. The human eye must adjust to the time when a vehicle enters or departs the tunnel. This is known as “adaptation lag.” People’s visual responses lag when cars enter the cave during the day owing to the rapid reduction in brightness, creating a “black hole effect” that makes it impossible to differentiate the situation in the cave; when the vehicle departs the tunnel, a “white hole effect” forms, generating extreme glare.

    To avoid an excessive difference in light intensity between inside and outside the tunnel, as well as a short-term visual obstruction to human eyes, the LED lights at the tunnel’s entrance and exit must be dense, reducing the light intensity difference between the outside and inside of the tunnel during the day and ensuring the driver’s safety.

    The LED lighting in the tunnel is usually constructed in two rows, which is also for the driver’s safety. In general, LED tunnel lights are separated into two rows with two lights on each side, with the top lights facing away from the ground so that they can illuminate the area without reflection.
