What is the cause of solar power led flood light not shining

When customers buy solar power led flood light, they often ask that the solar power led flood light purchased from other places does not shine after less than a year or more. Let's first look at the structure of solar power led flood light. In fact, there are some differences in the appearance of most solar power LED flood light, but the principle is the same. The core of solar power led flood light is LED light source (also known as LED lamp bead), LED power source (also known as LED driver). What if the solar power led flood light is broken, and the point is not bright, flickering, sometimes bright, slightly bright? The following gives you a detailed analysis of several common solar power led flood light is not bright reasons:

1.The bad power supply of LED projection lamp accounts for the majority of cases, and the power supply provides stable working voltage for the light source. Power supplies have problems converting AC power supplies to DC power supplies. It may lead to LED cast light is not bright and flicker, this generally cannot be fixed, need to directly replace the power supply. Of course, you need to determine the number of series, current voltage, whether the light source is full watt before changing, if you do not know how to change the power source, it is easy to appear bad or not bright enough.

2.the solar panel is damaged, in the case of the solar panel without any load connected to the multimeter test its voltage, the general system working voltage is 12v, normally will be higher than 12v voltage, only the voltage is higher than 12V can charge the battery, if less than 12V can not charge the battery. The solar street lighting system does not work or the working time is not enough.

3.LED light source damage, due to natural or man-made reasons caused by light source damage, resulting in solar street lamp system can not work, bright when not bright, flashing and so on.

4.the battery is damaged, in the case of the battery without any load connected to the multimeter test its voltage, the general system working voltage is 12.8v, under normal circumstances will be higher than 12.8v voltage, if less than 12.8V, it indicates that the battery feed, can not discharge, solar street lamp system can not work or work time is not enough. At this time we need to use the charger to charge the battery, if the battery can not be charged into the electricity, you need to replace a new battery.

5.The solar controller is faulty. If the solar controller is faulty, the solar power led flood light cannot be turned on or off. General controller failure indicator light will light up.

To sum up, the main reasons for solar power led flood light failure are LED light source, power supply, solar panel, storage battery and solar controller. In order to ensure the normal operation of solar light, regular maintenance and inspection of solar power LED flood light is essential.
