1834 new LED street lamps are added to the inner ring viaduct of the Puxi Section in Shanghai

20 years of service in the inner ring line of 20 years formally started the transformation of street lights. The Luqiao group of Shanghai city construction will change 1834 sets of street lamps, including lamps, lamps and parts of the pedestal, on the viaduct of about 29 kilometers between the Nanpu bridge Puxi bridge section and Zhou Jia Zui Road. The new street lamp will use LED energy saving light source. It is expected that it will take more than a year to complete the replacement.

Since the whole line was opened in December 1994, after nearly 20 years of operation, the 10 meter single fork steel bar road lamp on the viaduct has shown different degrees of fatigue or even "disease". According to the previous investigation, the lamp rods on the inner ring elevated on the surface caused by oxidation and rust stains, the light transmittance of the lamps and lanterns resulted in the decrease of light transmittance, the oxidation discoloration of the lamp reflector surface, and the decrease of the reflection property, which not only affected the lighting level of the road, but also wasted the illumination of the light. At the same time, the foundation of the lower end of the street light and the aging, corrosion or damage of the bolts and nuts between the lamp and the base, resulting in the hidden danger of the overturn and collapse of the individual street lamps.

The new street lamp will use the LED energy saving light source and lamps with low power consumption, high light efficiency and long life. The efficiency of energy saving can reach 50%. The new lamppost will be able to reach the 12 level of wind impact.

The reporter in the inner ring line Shanghai road to Wuning section of the road to see, because the construction is only allowed to work in the late night from zero to 5 a.m., to avoid the noise impact, the construction applied for the "anti-collision wall construction integrated portable operation device" patent, the device looks like a box. The builders work inside the box, and the noise can be reduced greatly. It takes only 15 minutes to install, without taking up the driveway.
