Pure solar street lights can be recharged on rainy days

At 7:30 yesterday evening, the first pure solar street light road in Chongqing was officially lit up on Innovation Avenue in the High-tech Zone . It is reported that these 37 solar street lights can save electricity and maintenance costs by more than 100,000 per year.

Chuangxin Avenue is not only the first pure solar street light road in Chongqing, but also the first in the southwest low sunshine area. At the same time, it is also the first demonstration project of the most powerful pure solar street light in the southwest. In addition to this road, 7 solar garden lights were newly installed at the west entrance of Caiyun Lake Wetland Park and were put into use at the same time. "It's brighter than before." Aunt Zhang, who lives near the Caiyun Lake Wetland Park, said that the road has been replaced with a new street lamp, and it feels better than before when walking.

Solar street lamps use LED light sources with a power of 140W for each street lamp , while the previous street lamps used high-pressure sodium bulbs with a power of 400W. Although the power is reduced, the brightness is increased. The 4 solar panels installed on each lamp can absorb solar energy for charging no matter it is cloudy or rainy. After a full charge, it can be illuminated overnight for 15 days without solar energy. And these street lights are very smart, and will automatically switch according to the daily ambient light changes. "It's dark, the lights turn on automatically, and the lights turn off automatically." The relevant person in charge said that such solar street lights are expected to appear on more municipal roads in the main city of Chongqing in the future.
