Nowadays, most street lamps have been replaced by solar lamps. We can often see a blackboard on the head of street lamps, which are solar panels.
In the future, solar street lamps will be used in many places. The obvious advantage of solar street lamps is that they can convert solar energy into electric energy, which is more green and energy-saving.
But the solar street lamp source is now basically an LED lamp source, the user reported that the solar street lamp often does not light, this is what we often say the dead light, Xiaobing here want to give you an analysis of the solar street lamp dead cause, can let you better understand why the solar street lamp dead.
The solar street lamp will die mainly because of its large leakage flow, which leads to the failure of PN junction, so the phenomenon of partial dead solar street lamp is formed, but the whole lamp will not be affected, and the only influence will be this small knot. There is also because the solar street light in the line is disconnected, resulting in the phenomenon of solar street light dead, so the fault but the whole lamp can not work normally.
So how can we prevent this phenomenon? To prevent static electricity, solar street light is extremely afraid of static electricity. Static electricity can damage LED so that the performance of LED will be reduced * failure will not be bright, so the prevention of static electricity for the prevention of solar street lights dead phenomenon is a very key step.
There is also a point to pay attention to in the production of solar street lights, is to try to choose solar street lights produced by manufacturers with automatic welding equipment, because the welding temperature of manual welding can not be controlled evenly, if the manual welding temperature is too high, it will directly cause the phenomenon of deadlights. The choice of automatic welding can fundamentally eliminate and reduce the occurrence of the solar street lamp dead light phenomenon.
