In order to meet the summer Davos meeting with a new look, since March 16th, the Dalian City Construction Bureau Street Light Management Office has carried out a centralized replacement of the street lights of more than 50 roads in the city.
On March 22nd, the author saw in Kunming Street, Shengli Road and Yinghua Street that the aerial work and streetlight workers were busy. In the old lamp cover that the street lamp worker dismantled, there is a thick accumulation of dust. It is understood that the replacement of street lamps first chose to carry out more than 50 main roads in the city. Most of the old street lamps replaced have been used for 7-8 years.
According to Liu, the director of the street lamp, more than 2,300 sets of lamps were replaced. The new streetlights feature a new high-pressure sodium lamp with an economizer and a time switch. The new and old lamps are basically the same in power, but the reflector design of the new lamps is more reasonable, the illumination range and brightness are larger and stronger, and the light transmittance of the lamp cover is higher. In addition, the new luminaires have better sealing than the previous luminaires, and it is difficult for dust to enter the lampshade to prevent dust deposition and shading from affecting the illumination efficiency.
