For the birth of solar street lights, it can be said that it has saved a lot of resources for our country, and it has brought great help to our country’s environment, and it has truly achieved energy saving, environmental protection and green requirements. Nowadays, solar street lights have attracted much attention, people have recognized it more and more, and the sales are very amazing. For solar street lights, it can meet some requirements of rural, school, development zone, and municipal road lighting, and provide design, research and development to production. For lighting products, it mainly includes solar street lights, solar LED linear lights, traffic lights and so on. For the installation and operation of solar street lights, Fengqi provides comprehensive technical support without any quality problems. At the same time, solar street lights have many significant advantages that are different from traditional lights.
LED linear lamp cap heat dissipation technology, generally uses a heat-conducting plate, which is a 5mm thick copper plate, which is actually a temperature equalizing plate, which equalizes the heat source; heat sinks are also installed to dissipate heat, but the weight is too large. Weight is very important in the street lamp head system. Generally, the height of the street lamp head is less than six meters. If it is too heavy, it will increase the risk, especially if it encounters typhoons or earthquakes, accidents may occur. Some domestic manufacturers adopt the world’s first pin-shaped heat dissipation technology. The heat dissipation efficiency of the pin-shaped radiator is greatly improved than that of the traditional fin-shaped radiator. It can make the LED junction temperature more than 15℃ lower than that of the ordinary radiator, and the waterproof performance is better than Ordinary aluminum radiators are better, and they are also improved in weight and volume.
In the field of solar power generation, solar street lights have an important position. The solar street light system adopts the form of “photovoltaic + energy storage”, which is a typical independent solar power generation system. During the day, there is enough sunshine for the photovoltaic cells to generate electricity to charge the battery, and at night the battery discharges to provide electricity to the street lights. A typical solar street lamp system is composed of batteries, batteries, street lamps and controllers. Its obvious characteristics are safety, environmental protection, energy saving, no need to lay complex pipelines, and no manual operation is required to execute automatically. Speaking of this, everyone must have a question, what does the controller do? This is also a topic I want to discuss today. In actual use, if there is no reasonable control of the battery, improper charging method, overcharge and overdischarge will affect the battery life, in order to reduce the protection cost, charge the battery in the most effective way, and of course, also discharge it reasonably.
The so-called reverse charging phenomenon is equal to the phenomenon that the battery charges the solar panel at night, so the voltage will easily break down and damage the solar panel. The controller will effectively prevent this phenomenon from igniting and ensure that the battery supplies power to the lamp normally. Reverse connection, as the name implies, means that the wiring is reversed. This will cause the lamps to be off or some other damage. When the controller detects that the wiring is reversed, it will send a signal to the staff to correct the wiring in time. Relative to the controller’s own protection when overloaded. When the controller load is too heavy and exceeds its own rated load, the controller will automatically disconnect the circuit, and after a period of time (the time set by the developer), re-open the circuit, which not only protects itself but also protects the entire system Intact. The controller also has a short-circuit protection function for lamps and solar panels, and blocks the circuit when it encounters a short circuit. Lightning protection means to avoid the devastating damage to the system caused by lightning.
