As the earth's resources become increasingly scarce, the investment cost of basic energy sources is increasing, and various safety and pollution hazards are ubiquitous. In recent years, under the keen demand from all walks of life for clean lighting energy and low-cost lighting electricity, solar lighting has emerged as the times require and has become the initial off-grid lighting mode in the new energy era.
Solar lighting devices can convert solar energy into thermal energy to generate steam, which is then converted into electrical energy through a generator and stored in batteries. During the day, the solar panel receives solar radiation energy and converts it into electrical energy output, which is stored in the battery through the charge and discharge controller; at night, when the illumination gradually decreases to about 101ux and the open circuit voltage of the solar panel is about 4.5V, the charge and discharge controller detects When the voltage reaches this value, the battery will be discharged to provide the power required for the operation of the lamp, light source and other lamp equipment.
Compared with the complicated installation of grid lighting fixtures, outdoor solar lighting fixtures do not need to lay complicated lines. They only need to make a cement base and then fix it with stainless steel screws. The installation is simple; compared with the high electricity bills and line maintenance of mains lighting fixtures High-cost, high-power solar lighting fixtures can achieve free electricity bills and no maintenance costs. You only need to pay the purchase and installation costs in one go. In addition, solar lamps are ultra-low voltage products, safe and reliable in operation, and there are no safety hazards caused by mains lighting lamps due to aging of grafted circuit materials, abnormal power supply and other problems.
It is precisely because of the strong economic cost benefits brought by solar lighting that it has derived different application forms, from high-power street lights and garden lights to small and medium-power signal lights, lawn lights, landscape lights, sign lights, and insecticidal lights for outdoor applications. , to household indoor lighting, mobile lighting fixtures represented by flashlights, etc., are all supported by solar lighting technology. Among them, solar street lights are the solar lamps with the strongest demand in the current market.
