With the vigorous development of new city construction, the sales of solar street lamps have rebounded rapidly, and many urban areas regard solar street lamps as an important choice for outdoor lighting. However, there are still a lot of people worried about its use life, that it is a new product, immature skills, short use life. Even though solar street lamp manufacturers offer a three-year warranty, there are still concerns. Today, solar street lamp manufacturers will take you to scientific analysis of the solar street lamp use life can reach how long.
Solar street lamp is a unique power generation lighting system, it is composed of battery, lamp pole, LED lamps, panels, solar street lamp controller and other components. There is no need to connect to the mains. During the day, the solar panel converts the light energy into electricity and stores it in the solar battery. At night, the battery supplies power to the LED light source to make it glow.
Solar panels
As you all know, solar panels, which are the whole system of power generation equipment, are composed of silicon wafers and have a long service life, which can reach about 20 years.
2. LED light source
LED light source is composed of at least ten light beads containing LED chips, the actual life of 50,000 hours, the deformity is by up to 10 years or so.

LED street lamp it is a kind of efficient solid state light source based on semiconductor PN junction formed with weak electric energy can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy. It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation.
3. Lamp posts
The lamppost is made of Q235 steel coil rod, the whole hot-dip galvanized treatment, hot-dip galvanized anti-rust anti-corrosion ability, even less protection 15 no rust.
4, controller
Individual controller waterproof sealing grade is higher, abnormal use of 5, 6 years is not a problem. Solar street lamp LED lamp head wire lithium control battery white cap separated, wiring attention to use electrical tape wrap.
To sum up, in general, the key to affect the life of solar street lights lies in the battery. When buying solar street lights, we advocate the battery to be configured larger, and formulate the life of the battery is his cycle discharge life, and the complete discharge is about 400 to 700 times.
If the capacity of the battery if only enough to put electricity every day, so battery damage very easily, however, the capacity of the battery is put charge how many times a day, that means how many stupid talents have a rebirth, it can greatly increase the service life of battery, and battery capacity is put charge how many times a day, is likely to ensure continuous rainy days longer.
At present, solar street lamps sold online are much cheaper than those of physical manufacturers. Users seem to have bought them cheaply online, but there are many hidden dangers, such as insufficient battery capacity, short life and no guarantee of after-sales service. The service life of the solar street lamp also lies in the usual necessary maintenance, in the early stage of the installation, to do strictly according to the construction standard, in the configuration of the reasonable collocation, increase the capacity of the battery, so as to extend the life of the solar street lamp.
The life of the battery is the key to the life of the solar street lamp!
