In recent years, solar street lights have been widely promoted and promoted. However, the editor found that in many places, two or three years after solar street lights were put into use, they were completely extinguished or needed to be replaced before they could be reused. If this problem is not solved, the advantages of solar street lights will be completely lost. Therefore, we must extend the service life of solar street lights. By visiting engineering companies to conduct market research, the editor found that the main reasons for the short service life of solar street lights are complicated when the solar street lights are off, the lights are not bright. Part of the reason is that many small manufacturers on the market do not have any technical strength. Their solar street lights are made up of various components; using inferior materials and accessories, the quality cannot be guaranteed, without core technology, it is impossible to achieve control, energy saving, and extended use. life. On the other hand, when buying solar street lights in some areas, they did not realize the important role of solar street light technological innovation. Through low-price bidding, various low-quality and low-quality products are rampant on the market, which seriously affects the service life of solar street lights.
Under normal circumstances, the life of solar street lights will exceed 5 years, and the life of street light poles and solar panels will last more than 15 years. The lifespan of ordinary LED light sources is about 20,000 hours, while those produced by regular solar street light manufacturers can last as long as 50,000 hours, which is about 10 years. The short board that affects solar street lights is the battery. If you do not master the core energy-saving technology, the lithium battery is generally about 3 years. Replacement, and if it is a lead storage battery or gel battery (a type of lead storage battery), if the electricity generated every day is only enough for one day, that is, the service life of about one year, that is, it needs to be between two Replace after more than a year.
On the surface, the battery is an important part of determining the service life of solar street lights, but the actual situation is not the case. If the same brightness can be achieved, the battery usage will be reduced, so the battery power can be extended for each deep cycle. Extend the life of solar battery. But the question is, what can be used to extend the battery life of each deep cycle? The answer is more power-efficient smart constant current and controller technology.
At present, few solar street lamp manufacturers in China have mastered the core solar control technology. Some manufacturers combine intelligent digital constant current control technology, and compared with traditional solar street lights, the highest energy saving rate exceeds 80%. Due to the super energy saving, the depth of battery discharge can be controlled, the discharge time of each battery can be prolonged, and the service life of solar street lights can be greatly extended. Its life span is about 3-5 times that of ordinary solar street lights.
