Is the LED decorative light string safe? What are the safety hazards?

Normally, LED decorative light strings do not have safety hazards. If the circuit is damaged, it will only consume power, and it is difficult for the light strings produced by regular LED decorative light manufacturers to have safety hazards. The reasons are as follows:

1. The input voltage of the led light string, the commonly used specification is DC 12V

2. The most popular solar powered LED lights are safer and do not need to be plugged in.

3. Strict production process and quality inspection procedures of regular manufacturers, and have passed market inspection.

But also pay attention, the LED light string used in a family should not be turned on for a long time. Due to the large number of LEDs, the light will be turned on for too long, which will cause heat. For safety reasons, there are people at home to turn on. Because many desk lamps, learning lights are turned on for a long time Overheating can also cause safety accidents. Although the LED current is small and the heat is small, there is nothing wrong with it!

Pay attention to safety. Indoor LED lights must be turned on by someone at home, and do not turn on for a long time. This long time means to turn on all night.

What are the reasons for the hidden safety hazards of LED decorative light strings? There are two possible situations:

1. It may be caused by the wrong connection of the neutral line of the switch. Although the neutral line is turned off, after the live line enters the light, an AC loop is formed through the distributed capacitance between the remaining neutral line segment and the ground~

2. The other case is because after the switch disconnects the live wire, because the broken live wire and the live wire pass through the same tube, it is also a distributed capacitor, which conducts the induced voltage of the live AC power line~
