Why is the first LED tunnel in Nanjing so dark?

"How does the model tunnel feel so dark? Make people feel depressed. "A lot of people from this tunnel will feel this way.

Nanjing municipal CPPCC members, city academy of Social Sciences Institute of urban development, Zhu Weiyi also paid attention to the problem. This year NPC and CPPCC, he brought a brief proposal, some suggestions for improving the model road tunnel lights, he found, in addition to the tunnel lamp is not bright enough, blue lights on both sides of the walls of the belt will also aggravate the gloomy feeling of oppression.

CPPCC members: into the tunnel on the tension

"This is a small proposal, however, I asked a lot of friends around, have the same feeling. Zhu said that every time he drove to the model road tunnel, he would suddenly nervous, afraid to run forward, because I feel very dark, can not see clearly. Especially in the winter, it is very uncomfortable, a kind of depressing feeling.

"This is the latest tunnel in the main city of Nanjing, but I think it is the most unreasonable in lighting design. Zhu said that the light will bring a lot of potential security risks, especially in the summer, the sun outside the glare, after entering the two eyes with a black, it is easy to have an accident.

Visit: the drum tower and the most dark tunnel model

Yesterday, I drove the field visited all the tunnels in Nanjing city.

The first is the go from rich mountain tunnel, feel bright; then went around to the Longpan Road, from Tongji gate tunnel and Xi'an tunnel, the door has been open to the Mount Jiuhua tunnel model road tunnel. After winding around the central road, Gulou tunnel to the direction of Xinjiekou. Finally, he went out of the Yangtze River tunnel.

Several other tunnel lights have a common characteristic: in the entrance, there will be a transition band, in addition to the incandescent lamp, and yellow light lamp, looks warm and bright, so enter, feel comfortable. However, the road model although there are transition band, color is not the same, some with a light blue, although some are yellow, but the color is shallow, and the lights are not bright enough, entered the tunnel, will feel more dark.

In addition, the drum tower tunnel light worse, only cold white light, no yellow light.

Management: LED energy saving, but the light is weak

During the interview, I learned that the dim light of the drum tower tunnel is due to its long history, when the design is not reasonable. Before the mountain tunnel is so rich, but the transformation after more bright. Let a person feel the most comfortable or Tongji gate and Xi'an gate, in addition to the lights, every once in a while and natural light can penetrate down, make people feel breathing easier.

Let the people go in and feel nervous model road tunnel, in fact, the first Nanjing LED light tunnel. 2008 when it was opened to traffic, the light is also a major bright spot, once the focus of publicity.

"LED lamp has its advantages, mainly energy saving and environmental protection. "Nanjing urban construction tunnel bridge management company, said the person concerned, at least save 20% ~ 30%. However, the use of the model road LED lights are early products. Its brightness is not as good as the ordinary incandescent lamp, more importantly, the scattering effect is poor.

In addition, the blue light waist, explaining that, in fact, the original is colorful, I don't feel so cold, but always due to tunnel water seepage, the light on the wall waist easily broken, often need to be replaced, simply replaced by a light source color, reduce the trouble of replacing.

What light should be used in the tunnel?

Nanjing uses solar lights

What kind of light is used in the tunnel, so that motorists feel the most comfortable? Nanjing urban construction tunnel bridge management company, said the proposal proposed by members is indeed an important issue. They are also doing research, but also trying to improve. For example, now the tunnel in Nanjing, the brightness of light, are adjusted according to the weather, when the sun is strong, it will be a little light.

Learned that Nanjing is now being prepared to use solar lights in the tunnel. At present, the transformation of the west road tunnel will be the first pilot? The source said that the west main road lighting design is being done, has not yet been determined, the principle is not only to energy conservation and environmental protection, but also to make people feel comfortable driving.
