A well-known LED lighting manufacturer has cooperated with the Beijing Municipal Government since 2019 and spent 100 million RMB to fully renew the eight tunnels and one underpass in the urban area. This not only saves a large number of electricity bills but also uses passersby’s illuminance has also been greatly improved.
Driving through the underpass can’t help but exclaim, because the Keelung Road underpass, which usually feels dim, becomes brighter after the full replacement of LED lighting. In the past, when vehicles passed through the tunnel, the lights inside were either too dim or too bright. I feel a glare when I get out of the tunnel.
Therefore, a well-known lighting manufacturer cooperated with the Beijing Municipal Government to spend 100 million RMB in funding from 2019 to replace the lighting of 8 tunnels and 1 underpass in the urban area with LED lights, and then adjust the brightness at any time through system monitoring to ensure the use of Passers-by are safe. People said, "Tunnel lights are different. The better one has been used for decades." Some people responded, "I don't know when I have changed that light and it feels brighter."
"When replacing LEDs with traditional light bulbs, in fact, we have probably completed more than 50%. An average energy-saving rate can basically be saved every year. The cost is calculated in tens of millions." Replaced with LED lighting. After that, not only the electricity bill of the tunnel was saved by 50%, but even the users felt that the lighting level was greatly improved.
Ophthalmologists also emphasize the use of LED lamps, whether they are tunnel lamps, household lamps or sign lamps, which can reduce people’s problems with overlapping shadows or glare due to light exposure. Wu Jianliang, director of the Department of Ophthalmology of Wanfang Hospital, pointed out, “If LEDs are used in tunnels, compared with the original light source, the light source will be more uniform and the brightness will be more uniform."
