Solar street lights stop working need to be analyzed and checked one by one, there may be insufficient power, a system is broken, the lamp is burned out due to weather reasons or circuit board short circuit and other situations. So, when the solar street lamp stops working, we need to check to know which parts are broken.
What is the reason why solar street lamp works abnormally?
According to the reaction of some villagers, LED solar street lamps have intermittent work problems in the process of night lighting, that is to say, the light source suddenly goes out when working normally, and then automatically lights up again after a while. The maintenance staff did not find any problems with any of the components after inspection, which was puzzling. When asked what was wrong with the night when the situation occurred, the villagers replied sharply.
Found this problem is in the New Year 30 these days, he said that there is no abnormal night, did not find naughty children play tricks, is a set off firecrackers lights will be extinguished, such as put out after a while on the bright again. Is it really strange, is the solar street lamp afraid of noise and shock? This also does not make sense ah, when further inquiry we seem to find the cause of the problem, the Spring Festival people most like to set off firecrackers is the double gun, let's analyze the working principle of solar street light, understand its working principle after this strange problem will be solved.
The solar street lamp depends on the controller to coordinate the components according to the program. During the day, the solar panel absorbs sunlight, converts the light into electricity, and then stores the electricity into the battery through the controller at a voltage of about 16V. When it gets dark, the light absorbed by the solar panel is low or even no, at this time, the electricity imported by the solar panel to the controller is extremely limited. When the voltage is below 5V, In other words, the solar panel is no longer able to generate power, and the light source will turn on automatically for 5 minutes (depending on how long the controller is set).
At this point we should have some understanding of the strange phenomenon, the firing of the double gun is usually carried out on a welded turret, the large turret can hold more than 100 double guns, so that when one is ignited together with the others, dozens will fly up at a time, Such a series of explosions in the sky would be bright enough to generate a voltage of more than 5V from the solar panel, when the controller received a voltage of more than 5V, the LED light will immediately stop working.
This is the main reason for the intermittent work of solar street lamps. In similar cases, there is no need to repair, because there is no quality problem of the first product. After the double gun, the lamps and lanterns will naturally return to normal work.
After all, the solar energy industry is the future of resource allocation in the world. Now solar street lamps have entered people's lives. Wherever we go, we can see many solar street lamps, proving that we have entered a new energy era. As we of this era, we have reason to know more about the industry
