Solar street lights use solar power, battery storage, and controllers to control the charge and discharge of the battery. Controller is divided into light control and time control two. During the day, when sunlight shines on the surface of the solar cell, the energy generated by the solar cell charges the battery through the controller; at night, the light gradually weakens, and the operating voltage and operating current of the solar cell continuously decrease, when the operating voltage is less than the controller setting. At the time of voltage, the controller starts the load and the solar street lamp lights up. When the set time or the ambient light is too strong, the controller automatically turns off the load and the solar battery starts charging. This continues to cycle.
Solar street light adopts high-efficiency single-crystal (polycrystalline) silicon solar battery power supply, uses VRLA batteries to store electric energy, uses highly efficient energy-saving lighting, and adopts advanced charge and discharge and lighting control circuits, with reliable performance, high luminous efficiency, high brightness, and easy installation , No need to lay cables and wires, no need for AC power and electricity, DC power supply, photosensitive control, safety, reliability, energy saving, economy, environmental protection, practicality (depending on configuration and model, charging is available for 3 to 7 days a day), long life ( Solar cells can be used for 15 to 20 years, batteries can be used for 5 to 7 years, etc., and are the future direction of outdoor lighting.
With the increasing shortage of energy in the world, more and more attention has been paid to environmental protection and energy saving solar energy, and the use of solar street lamps is also increasing. With the continuous development of solar energy technology in our country, solar street lamps occupy a certain share of the occupier market with its unique characteristics.
The development of solar street lamps is a typical performance of the development of solar power generation technology. It is also a direction for the country to promote energy conservation and emission reduction to support clean new energy sources. With the promotion of a variety of factors, solar street lamps have experienced rapid development. That is, its speed of development and the attraction of the Chaoyang industry, more people joined the army of solar street lights promotion, so it will inevitably increase the industry's risk factor, exacerbated its competition.
Everyone knows that neither the fierce market competition nor the development bottlenecks of the industry are important factors affecting the development of the company. The new technology and new inventions are used to reduce costs and break the bottleneck to maintain the leading level in the industry. Recently, the newly-developed solar street light controllers and LED street light controllers have broken new challenges that affect the control of solar street lights and LED street lights.
The solar street light special controller is designed for the solar DC street lamp system. It adopts a single-chip microcomputer control unit and a serial PWM charging main circuit to realize intelligent control. A two-button tactile switch completes all operations and settings. With short circuit, overload, anti-reverse, overcharge, over discharge, automatic shutdown and automatic recovery protection functions and solar power complementary functions. The controller samples the parameters related to the charge and discharge control such as the charging voltage of the solar panel, the charging current, the terminal voltage of the storage battery, the discharge current, and the ambient temperature through the computer chip, and realizes the charge-discharge control with temperature compensation conforming to the characteristics of the battery. High-efficiency PWM battery charging mode ensures that the battery and the lamp work in the best state, greatly prolongs the service life of the battery and the lamp, improves the charging efficiency of the solar energy to the battery and the working efficiency of the light source circuit; has a variety of work modes, output modes select. The LED street light special controller can adjust the lighting time and the light source power of each time period according to various requirements. The overall design basically takes into account all aspects.
With the continuous improvement of solar photoelectric conversion technology, solar street light controller technology, new light sources, and the gradual reduction of the cost, the development of solar street lamps will bring us more broad prospects and more beautiful urban scenery.
