With the entry of solar street lights into the market and rapid development and evolution, solar street lights have become one of the most representative of new energy use in the lighting industry in the 21st century. The advent of solar street lights is an energy-saving and environmentally friendly solar energy researched by people through science and technology and the use of natural energy. Outdoor street lights are a green technology lighting revolution that is a sign of social development. The wattage of our regular ordinary light source is at least 250w or more, so that its brightness can meet the requirements of road lighting. If the LED light source used by solar street lights is used in rural roads, the brightness is only 15w-30w. It is very bright, that is, the brightness of the 50w light source of the solar street lamp is almost the same as that of the conventional street light 250w. Moreover, with the lack of energy, people’s awareness of energy conservation and environmental protection is gradually strengthening. The development trend of solar street lights is unstoppable. Similarly, the development of solar street lights is also a huge lighting transformation in the lighting industry. I believe that in the future, solar street lights will be Can replace the use of conventional street lights.
