[0002] Street lights refer to lamps that provide lighting functions for roads. They generally refer to lamps within the scope of road lighting in traffic lighting. They are the main components of urban lighting projects. Street lights are widely used in various places where lighting is needed. The use of street lights improves the safety of people driving at night and facilitates the walking of pedestrians at night, providing great convenience for people's lives. While playing an important role, it also consumes a lot of energy. Traditional street lights are mainly high-pressure sodium lamps. The power of a street lamp is about 100W~400W, and the energy consumption is very huge. With the continuous strengthening of the national new energy energy-saving and environmental protection policies, gradually reducing coal-fired power generation and increasing the use of renewable energy will be the development direction of the country's future energy policy. Therefore, the use of solar street lights to replace traditional city street lights can be regarded as an important means of energy conservation, emission reduction and air pollution control. Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-controlled sealed batteries (colloid batteries) to store electricity, and ultra-bright LED lamps as light sources. They are controlled by intelligent charge and discharge controllers to replace traditional public power lighting street lights.
