The street lamps on the road are indispensable in our life. Nowadays, most of the street lamps on the road are led street lamps and energy-saving street lamps. And the average life of energy-saving lamp is about 6000 hours, while the average life of LED street lamp is about 55000 hours. You can see how much energy-saving LED street lamp is compared with energy-saving lamp. The LED street lamp is more than 60% energy-saving than energy-saving lamp. And the quality of large factories and small workshops can also affect the service life of LED street lamps.
There is also a controller, controller: controller is one of the core components of LED street lamp, which plays an important role in the whole LED street lamp system. It not only controls, monitors and protects the working state of photovoltaic modules, batteries and loads, but also indirectly protects the loads (LED street lights) while effectively controlling the working state of the batteries, providing an effective and relatively stable working environment for the functional set. Therefore, the controller with stable performance and reliable quality will greatly extend the service life of solar street lamp.
Batteries: the most common batteries used for LED street lamps are gel batteries and lithium batteries. They are cheaper than lithium batteries, but their life expectancy is much shorter. At present, the service life of colloidal battery in China is no more than 4 years at most, while that of lithium battery is 5 years at least, so in many places, the LED street lamp will not light up after three or four years of use
