In recent years, the concept of energy conservation and environmental protection has become more and more popular. Energy-saving transformation of street lights in many areas is being implemented. Traditional street lights are replaced with LED lights. At the same time, they are trying to install multi-functional smart light poles and install single-light control systems, which can be variable power. control. If there are few pedestrians on the road at night, the power can be reduced to meet the travel needs of a few people and save resources and costs. If it encounters rainy days during the day and the light is dim, these street lights can also be used for low-power lighting to supplement the lack of natural light perception and ensure the safety of vehicles and pedestrians.
