Working principle: First, install and use the main body 1, and then turn on the LED light 103 through the rotary switch 4 during use, and use the lithium battery 107 to provide energy. It has a long service life, extremely low power consumption, frequent switch use, and small size , High brightness, very suitable for outdoor use, can improve the practicability of the device, and also has excellent seismic performance, its safety and service life are effectively enhanced, and then the device adopts the design of the shell 3 to wrap the folding solar panel 105 , The magnetic ring 104 is magnetic and can absorb the shell 3. When disassembling and installing the shell 3, the user only needs to pull out the shell 3, which greatly facilitates the user's use. Then, the foldable solar panel 105 passes through the rotating shaft 106 is contracted and stretched. When charging, remove the casing 3 and unfold the folding solar panel 105, and use the sun to charge the lithium battery 107. This effectively solves the problem of excessive space occupied by ordinary solar lamp panels, and is very suitable for portable use. And after folding the foldable solar panel 105, its structural stability and shock resistance are improved, and it is not easy to be damaged. It has the characteristics of fast charging, portable use, flexible and stable. Finally, the lithium battery 107 has high capacity and can be reused. , The advantages of safety and stability can reduce the number of charging of the device, provide energy for the LED lamp 103 for a long time, and increase the service life of the device. This is the working principle of this portable solar lamp.
