Deputies called for slowing the replacement of LED street lamps

Kept hidden street

Pazhou Hall outside the blue glare pose a safety hazard

Night in Pazhou Hall, a blue band of light outlined the contours of its ups and downs, and read across the Pearl River Road has been extended to the shore, a distance, the blue arc of this beautiful and dreamy, but had to drive through the night The people here, Miss Jiang, however, it is a "blue nightmare."

Miss Jiang who lives in Jubei, work in the village of interchange off, overtime, she often Pazhou Hall on the night along the river road outside the drive home reading, "Every time you start to see a few hundred meters away from this block in the Blu-ray on the road than the road and around the lights are much brighter, people drove through the glare of the blue when starting a shade to block the eyes and even "eyes closed through", or simply open eyes, if it was just a roadblock or pedestrians passing may lead to traffic accidents on the recent good point, plus the white bar, not so "miserable blue", and can be more bright. underneath the car after a band of light when the light hit the front directly on the glass, moment are not clear way, and really afraid of something happening. "

Miss Jiang encountered is typical of the "glare" (referring to the brightness of vision due to inappropriate distribution, or exist in space or time on the extreme brightness contrast, resulting in visual comfort, the human eye can not adapt to the feeling of light), part of the landscape lighting, road lighting effects. Liu Di strong lighting expert says. The purpose of road lighting is to identify the driver in front of a good road conditions, traffic safety and to ensure comfortable driving at night. Qualified lighting must consider the driver's visual requirements, facilitate the driver can quickly and accurately obtain information about road traffic information.

Pazhou Hall effect of light on the drive with the situation, the reporter interviewed the City Construction Committee thank the Director of the city environment office, said he is planning for the Pearl River to adjust the light engineering, including the Pazhou Hall, "We will make public comments adjustment. "

Central City Road and other roads of trees block light microscopic passers-by

"In fact, according to the road than the more light the better, more important is lit evenly, there is no" zebra crossing "." Network Technology Co., Ltd. Guangzhou Guangya says operations director Zheng Yaqin.

Guangzhou is one main road lights on Central City, according to the road very uneven. Mon 21:00, correspondent in Central City Road Garden Hotel section to see that because wooded and low lights, a lot of lights are "buried" in the crown among the trees blocking the road is not very bright, but the shade of a tree near the sidewalk under the road is relatively dark.

Mr. Wang told reporters that the car, driving at night in Central City Road, pedestrians are most afraid of a taxi, "Some people come to play on the road, still standing under the shade, the dark to the front to see someone, almost hit. "There are sections in the Central City Road Huaguoshan traveling near the taxi driver told reporters that the fear experienced black taxi at night," where the street lighting is not enough if they just wear darker clothes, really do not see people unless they laugh about showing white teeth, only to wake up where the driver was in a taxi. "lush evergreen trees in Guangzhou because the four seasons, the leaves stop lights, street lamps by leaves or" parcel "," buried "in case everywhere, affecting many sections of the lighting effects.

Zheng Yaqin suggested, the garden department and street lights to be fully coordinated, on the one hand affect the timely pruning street street lighting, too dense tree trunk, on the other hand consider the increased street level, or a small increase in the lower part of street lights, to avoid the crown block.

China Dongfeng Road proposed light reflector angle adjustment

Last year, Dongfeng Road, put on 400 new of Chinese lamps, each lamp 10 lamp. Look closely will find that the sky lights shine the light cf the road more, not only a waste but also the formation of light pollution. In Guangzhou, it is difficult to see stars, let alone such a beautiful Star Galaxy, one of the reasons is that shooting the sky light pollution caused by too much light. So now the light not lighting industry have emphasized the direct sky.

Lighting experts Liu Di Qiang, Chinese lamps in each lamp has a reflector, reflecting light to create the effect, he suggested adjustable reflector angle, so that according to some more light to the ground.

Tunnel lighting should be appropriate

Avoid strong visual difference

Road construction in Guangzhou, there are more and more tunnels, taxi driver Lin master feeling, "Some tunnels are too bright at night that go in front of a white out and find a black eyes."

There is a lot of tunnel lighting, "zebra" effect, the area between the two lights marked black. If Yuejiang the road in front of the beer museum, there is a Modiesha tunnel, the middle one black one with the street light, easy for drivers to produce visual fatigue.

Professional Lighting Magazine, "Aladdin" and Li Ping, editor of the tunnel as a special section on the road, over time tunnel external brightness changes, and when the vehicle into, and exit through the tunnel in the process will produce a series of visual problems.

If the tunnel is short, you can see outside the exit from the entrance of high brightness, sharp vision is poor, known as the "black box" effect, when the driver of the tunnel exit is more difficult to adapt to the brightness; if the tunnel is longer, when the vehicle Just enter the tunnel, the export will feel very black, near the exit can not even recognize the situation, known as the "black hole" effect, and vehicles in long tunnel running for some time, close to the tunnel exit, the exit light and the darkness of the tunnel the formation of a strong visual difference, you will see a dazzling "white hole", known as the "white hole effect." In the long tunnel of the "black hole" and "white hole" effect is easy for the driver because of the gap arising from the visual light error or even to determine the impact on driving safety. If you adjust the lighting inside the tunnel moderate, can reduce and eliminate these visual differences.

Whether the change LED lights?

LED light power does not save money

Lights in addition to ensuring road safety, in recent years vigorously promoting the "energy" requirements. In early 2009, in order to expand domestic demand, promote the development of China's LED industry to reduce energy consumption, China Science and Technology launched the "city of ten thousand," semiconductor lighting demonstration cities program, the program covers Beijing, Shanghai, Shenzhen, Wuhan and other 21 in the developed City plans to install in three years several million LED lights. January 2010, according to the Guangzhou Daily reported that Guangzhou has announced 25 billion investment in three years to promote LED lights. According to the Guangdong Provincial Association of lighting the whole Jian, before the Asian Games, Guangzhou has 50,000 street reconstruction for the LED lights, this year will replace 11 million LED lights.

Provincial electricity than LED lights installed, maintenance

The high cost of LED lamps, lighting, maintenance of harmony is a recognized fact. "At present, an LED lamp at least 4,000 yuan, poles, chips, etc. at least 2,000 yuan." Lighting industry Zheng Yaqin, said, "LED lights to maintain expensive, because there is no uniform standard LED lamps, the manufacturers own production, generation of products and very quickly, Some LED lamp is broken, look for manufacturers, manufacturers say that I already do not produce this model, and had to replace even the poles together. "

Although the power LED, etc., but not money. It is understood, LED street lamp power consumption is now 1 / 5 ~ 1 / 7. Lighting Association, Guangdong Province, the whole Jian, China's LED technology is not mature enough, although in theory the LED lamp life should be more than a decade, in fact, reach. So count update maintenance costs, expensive.

In fact the Chinese Ministry of Science, "Ten thousand ten cities" covering 21 cities, only a few cities to put a clear installation plan away at the end of Kunming and even LED lights to say "NO", refused to install. Power Supply Bureau of Kunming calculations, think LED lights to save electricity is far less than the installation and maintenance costs.

For LED lights should be carefully

Guangdong Provincial People's Congress Sim waterfall that, in the same light intensity, LED light is not energy-efficient than the high-pressure sodium lamps. Currently this technology is still in the exploratory stage in the world, the northern part of the city after the pilot, are gradually reducing the use of LED lights, large-scale promotion in Guangzhou can not blindly, replace the LED lamp should be careful.

LED technology is not mature in the conditions, it should be suspended in Guangzhou to promote the pace of replacement LED? Quan Jian said that this is part of the experts and scholars, LED is the future direction of development, the Government should support, and government support in recent years has also been significant results, LED technology has made rapid progress, compared with 2008, LED lights 60 watts of lighting from up to 100 watts, the chip reduces the price from 10 yuan to one or two dollars. Over time, the LED lamp technology is more mature, more effective energy-saving lighting, and maintenance costs when the price cheaper then a large scale replacement of LED lights more affordable.
