Street lights originated in the 15th century, and the original purpose was to brighten up the dark nights of London in winter. The mayor of London issued an order to hang lamps and lanterns outside for lighting. This is the initial form of street lamps. In the 16th century, Louis XIV promulgated the city road lighting decree, so many street lights were installed on the streets of Paris. But it didn't attract many people's attention at the time. Nowadays, road lighting often attracts the attention of the whole people. In the beginning, the street lighting was relatively weak, using candles and oil. After using kerosene, the brightness has improved a lot. After Edison invented the incandescent lamp, electric lamps began to be used in large quantities for road lighting.


In the 21st century, "energy saving and emission reduction" has become a global development concept. Among them, lighting energy saving is a very important part of "energy saving and emission reduction". Traditional lighting brings a large amount of carbon dioxide and other gas emissions, which has a great impact on the environment. Street lights occupy a considerable share of electricity consumption for lighting. It is imperative to promote green lighting. Therefore, people began to explore and apply new green lighting power supply methods. Solar energy is widely used in the outdoor lighting industry because of its energy-saving, pollution-free, and inexhaustible advantages.


Solar street lights are composed of controllers, solar panels, batteries, light sources and other accessories. As a new energy source with long lifespan and high luminous efficiency, LED light source has gradually replaced the low-efficiency and polluting light source in the past as soon as it was launched. The combination of solar energy and led light source has become the most popular solar led street light on the market. The rapid development of solar cell technology and the innovation of light source technology make solar street lighting more and more popular. The current solar street lighting system has been very mature, completely dispelling the initial concerns of whether the solar power generation is stable and the service life is sufficient. Solar street lights have been installed on both sides of roads, parks, highways and other places. With the maturity of solar street lights, the application of garden lights and lawn lights has gradually taken shape, and the development of solar LED street lights in the field of street lighting has become increasingly perfect.

With the quiet rise of the concept of smart cities around the world, many developed countries have actively carried out the construction of smart cities, organically connecting public service resources such as water, electricity, oil, gas, and transportation in the city through the Internet to provide better services. To meet the needs of citizens for study, life, work, medical care, etc., and to improve the government's traffic management and environmental control. Street lights not only carry the lighting of urban roads, but also carry people's demands for a better life. Solar smart street light is a combination of solar street light and smart city. In the future, the solar led street light may develop further.
