Nanjing street lighting revolution average illuminance increased by 50%

Street and each citizen travel related. Recently, the reporter learned from the city street management office, the implementation of the 15 year street lamp standards will be refreshed this year. In 2006 the next 5 years, Nanjing street lights will have some revolutionary changes - the average street light intensity increased by 50%

Street lamp standards, "scientific name" is "urban road lighting design standards". Reporters learned from the city street management office, the implementation of the old standards will be introduced in 1991 this year, revised edition. In the light of public concern, for example, an average of 50% higher than before.

City streetlights Management Office chief engineer Guo Shaohua told reporters that the road average illuminance of the expressway and 1991 Street version of the standard is 20LX, (commonly known as lux, illumination, unit) this year, according to the requirements of the program, the average illuminance to 20LX--30LX; trunk road, Yingbin Road, city commercial center or the center of the road, but also by the average illuminance 15LX upgrade to 20LX-30LX.

The sidewalk to light

Which is more relevant to the environment than the public travel data. Guo Shaohua case, the environment is more than the sampling point is 5 meters away from the fast trunk road, where there may be slow lane may also be sidewalk. The main road around the lighting environment, there are specific data requirements of the environment than the minimum value of 0.5, that is, the average illuminance of at least 10LX.

Crossroads street a head

Another relationship between the "street lamp revolution" is that the planning for the first time provides the average level of illumination, illuminance average. Crossroads will consider lamp enabled superior head ".

The high pole height of at least 15 meters -18 meters or more. Previously, because of the special terrain intersection, the central area of the road can not be paved. Therefore, the urban street lamp suffered "fault", and most of the street lamps were illuminated by Yu Guanglai.

This is an obvious case near the inner bridge. The remaining light is limited, often appear dark near the crossroads. In this regard, the new 5 year plan quantifies the average illuminance of the intersection (the main road is 30LX--50LX). Will continue to enable high pole lamp, high light effect as far.

District old street lamps gradually improved

The next 5 years, the district will gradually improve the old street lamps, alleys and residential use of high-pressure mercury lamp, will be gradually replaced by energy-saving lamps or electrodeless lamp. The high-pressure mercury lamp is the mainstream street in 69s, compared to the current high pressure sodium lamp used for illumination are insufficient (HPML in more than 50 watts, only 40 lumens per watt light flux; high pressure sodium lamp at 100 watts per watt flux reached 100 - 140 lumens).

At the same time, the old high pressure mercury lamp mostly uses the enamel cover, below is a bulb. Waterproof and dustproof grade can not reach professional standards, and thus affect the quality of lighting. At the end of March, city street management office in Ruijin Village District of the existing street lighting effect is not ideal, the 20 old street lamp light source of mercury modified sodium.

Reporters witnessed: these places bright

April 22nd evening, the reporter conducted a small survey of Nanjing street. Some advanced lighting features have been quietly appeared in the streets of Nanjing.

[Key words] Y street lamp

From the south to the north into the Xianghe Road, the reporter walked into the Xianghe market, it was found that this new type of Y street lamp, like flowers two, bear the fast track, sidewalk lighting function;

21:20, came to the new model of the road, the reporter found that here is a Y street lamp. The fast lane is wide, the street lamp is designed with two light bulbs, and the one who takes on the road lighting is a light bulb. Experts said that there is no problem of road lighting, sidewalk lighting to ensure quality.

[Key words] pole investigation

22 on the evening of 9, the reporter went to the drum tower square. At the moment, the four corners of the world in four directions, were erected a pole. By 10 meters above the 4 lamp pole lamp, the night lights illuminated Gulou square.

Reporters observed in the vicinity of the square, here is a large car flow place. Because the "height" is high, these high pole lighting radiation to the side of the sidewalk. Whether it is in the drum tower on the west side of the public square, or drum tower section of Zhongshan North Road, the public is also very convenient to walk.
