Shanghai inner ring elevated west of the replacement of LED street lights brighter and more power

Daily economic news reporter 14, was informed that the use of nearly 20 years of the inner ring elevated Pu West (including ramp) more than 1800 sets of high-pressure sodium lamp will be updated, with a metal halide lamp and LED lamp instead. Compared with the existing high pressure sodium lamp, the energy efficiency of two kinds of light sources can reach 45% and 57%, respectively.

Lamps and light poles are to be changed

Street lights are the eyes of the city, in the development of the city, "look at the floor during the day, at night to see the light," saying, street lights, is no longer a single night lighting tools, but also shows the city's development, vitality and even fashion. When people drive every day in the inner ring elevated, may not be aware of these lights have been in service for nearly 20 years.

The inner ring elevated road length of 29 kilometers, open to traffic on December 1994, including East to West Hutai disk arm of the project opened in December 1993. After nearly 20 years of operation, the elevated street also showed different degrees of weakness or even "disease".

The deputy general manager of Shanghai city construction design institute general contracting Department Ye Xiao told the Post reporter yesterday, after a survey found that the current inner ring elevated on the pole surface due to oxidation and rusting, the lamp transmission cover because of aging caused light transmittance decreased, lamp reflector surface oxidation discoloration, reflecting reduced performance, which makes the decline in road lighting level and directly affects the traffic safety, but also a waste of electricity for lighting. At the same time, the part of the lower part of the street lamp, as well as the connection between the lamp post and the base, such as bolts, nuts, etc., are corroded, damaged or damaged. "Now in the inner ring elevated street lights are not allowed to hang flags and other things, is worried about the wind with a light pole. "

According to the program, through the transformation of the inner ring elevated street lamps will be mainly in the security, function and energy saving 3 aspects to effectively improve and enhance. Take the repair or update on the lamp base part of the way to improve strength, based on the pole will be replaced, the new pole height is 9.5 meters, with the existing Lightpost highly consistent wind impact and can reach Shanghai in 50 years.

Now the inner ring light source is a high-voltage sodium lamp, each lamp power of 250 watts, the average illuminance requirement is 20 lux. The new light source lamp will reach 20 lux standard, use warm the same, but the light source used for LED lamp metal halide lamp or the price is more expensive, the new light source will be determined by the end of street management, but the energy consumption will be greatly decreased, compared with the existing high pressure sodium lamp, energy efficiency two the light source can reach 45% and 57% respectively.

When the construction of bright lights half

The inner ring elevated road street reconstruction project, South South Bridge Approach of Nanpu bridge, north to Zhoujiazui Road, a joint bid by Shanghai urban construction design institute and the Shanghai urban construction group in Luqiao. Due to the long distance, multiple sets, the entire renovation project is expected to be more than a year to complete.

It is understood that the repair of street lamps is a difficult transformation. There are two forms of the inner ring elevated road lamp, the reinforced concrete and the steel structure, and the aging or damaged condition of each street lamp base is also different.

"We according to different situation, 5 design scheme, the reinforced concrete foundation, have all or part of the update after the chisel chisel after reinforcement, chiseling and part according to the actual situation, take a different approach. "Ye Xiao said, taking into account the night construction noise control requirements, will use hydraulic splitting machine instead of usually used to pick chiseling Street foundation, and the use of protective cover, avoiding chiseling concrete debris falling.

Due to the inner ring elevated traffic flow, can not be closed road construction, so the transformation of the time every day will be zero to 4 in the morning, 5 o'clock. But just four or five hours it is difficult to complete the transformation of a street lamp, the transformation process will take a street lamp separated by a street light way to ensure that the construction of the most basic lighting requirements.

After the transformation, the inner ring elevated on each street in the style will not make people feel significant changes in illumination will be improved. Every night in the future, the familiar orange light is still lit up, lighting up the elevated road, just inadvertently, these lights are replaced by a new".
