Generally speaking, LED decorative light strings do not have potential safety hazards. If the line is damaged, it will only consume power, and it is difficult for the light strings to have potential safety hazards. The reasons are as follows:
1. The input voltage of the led light string, the commonly used specification is DC 12V
2. Now the more 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 been tested by the market.

However, it should also be noted that the LED light string used in a family cannot be turned on for a long time. Due to the excessive number of LEDs, turning on the lights for too long will cause heat. For safety reasons, only people at home should turn on the lights. Because there are many desk lamps, the learning lights will be turned on for a long time. Overheating will also cause safety accidents. Although the LED current is small and the heat is small, nothing is guaranteed!

What are the reasons for the safety hazards of LED decorative light strings? There are two possible situations:
1. It may be caused by the wrongly connected zero line of the switch. Although the zero line is turned off, after the live line enters the lamp, an AC loop is formed through the distributed capacitance between the remaining zero line segment and the ground~
2. Another situation is that after the switch disconnects the live wire, because the disconnected live wire and the live live wire are both passed in a conduit, it is also a distributed capacitance, which conducts the induced voltage of the live AC live wire~
