LED decorative light manufacturers tell you what factors cause the damage of LED lights
Due to the characteristics of energy saving, environmental protection and long life, LED decorative lights are now more and more demanding, but people often use improperly in daily life, resulting in LED lights no longer "long life", so the common reasons for the damage of LED decorative lights are What? LED decorative light manufacturers will tell you the main reasons for the damage of LED lights:
1. The power supply voltage rises suddenly, and the surge increases.
2. A component or printed circuit or other wires in the circuit are short-circuited, resulting in a partial short-circuit of the LED power supply path, causing the voltage at that location to rise, and the solder joints to be welded or loosened.

3. Some LEDs are short-circuited due to their own quality damage, and the original voltage drop is transferred to other LEDs. The internal resistance of the LED changes, and the voltage across the LED is uneven.
4. The temperature in the lamp is too high, which deteriorates the LED characteristics; the temperature in the lamp rises too fast; the temperature is too high during soldering or tin immersion.
5. Water enters the lamp, and the water is conductive. The hot air flow inside the closed lamp tube accumulates to form water vapor or mist.
6. In the light source test, turn on and off quickly, and the charge between the electrodes discharges (that is, fades out when turned off).
7. Erosion of washing water and ultrasonic nanowaves during washing.
8. Live operation; all fixtures and fixtures are anti-static; keep the temperature and humidity of the environment.
