As the society continues to promote green, energy-saving, low-carbon life, people's awareness of environmental protection is slowly increasing. So with the popularity of solar water heaters, solar energy can be seen as an inexhaustible and inexhaustible safety and environmental protection new energy source. Solar led street light have also begun to have its market position, and it is necessary to make solar LED street light more popular. To analyze, it is necessary to analyze and compare the effects of the mains light. With the increasing emphasis on the new energy field, the photovoltaic industry is also in the stage of expansion and popularization, and the use rate of solar LED street light is gradually increasing, especially in industrial parks, factories, rural road projects and other places. The solar LED street light is generally composed of a solar controller, a solar panel, a battery, a light pole, a light, etc., wherein the solar controller is a core component of the solar LED street light.Other advantages of solar LED street lights: green and environmental protection, can add new selling points for the development and promotion of noble ecological communities; sustainable reduction of property management costs and reduction of the cost of the public share of the owners. In summary, the inherent characteristics of solar LED street lights without hidden dangers, energy saving and no consumption, green environmental protection, easy installation, automatic control and maintenance-free will directly bring obvious advantages for the sale of real estate and municipal engineering.The solar LED street light consists of the following parts: solar cells, batteries, special controllers for solar street lights, illuminators and light poles.The solar LED street light is an automatically controlled working system that automatically runs when the operating mode of the system is set. Solar LED street lights are ideal road lighting. With the improvement of people's life and the continuous development of society, it will be widely used, so that the sun gives the light of the earth to illuminate humans at night.
