As a kind of 'inexhaustible' new energy, solar energy not only solves the problems of energy crisis and environmental pollution, but also brings many channels for people to get rich. Many domestic enterprises invest their human and financial resources in the research and development and utilization of solar energy, and street lamps are no exception. At present, solar street lights have gradually replaced traditional street lights and become the “lights of thousands of families” that can be hot with bare hands, and have shown a tendency to “encircle the countryside from cities”. Compared with traditional street lights, solar street lights have many advantages. For example, solar street lights use solar energy, which is very environmentally friendly, simple to install, no need to build cables, and can be completely light-controlled according to light perception, automatically shut down during the day, and at night Automatically turn on, greatly saving electricity bills. Speaking of rural areas, in our impression, rural villagers usually use flashlights when they go out at night. However, they have now 'eliminated' flashlights because they now have solar street lights. The blue and white rural solar street lights are lined up beside the small roads between the villages. Compared with the previous days when there were no solar street lights, the villagers basically don’t like to go out at night. One, and I worry about losing the flashlight, but now that with solar street lights, villagers basically don’t need to rely on the flashlight at home when they go out at night. With the acceleration of the construction of new countryside, low-carbon and environmentally friendly solar street lights have entered more and more rural areas, which not only effectively reduces the loss of electricity, but also greatly reduces the burden of the people. In the past, if it was in the countryside, it would be impossible to reach out when it was dark, and traffic accidents also occurred from time to time. If you want to visit one's home, there is no street light, and it is very inconvenient to travel at night. Nowadays, the installation of solar street lights not only illuminates the dark night conditions in the countryside, but also improves the rural infrastructure. It can be said to illuminate the new life of the villagers and become a beautiful scenery in the countryside.
