What are the factors that cause damage to LED decorative lights?

Due to the characteristics of energy saving, environmental protection and long life of LED decorative lights, the requirements are getting higher and higher, but people often use them improperly in daily life, resulting in LED lights no longer "long life", so the common cause of damage to LED decorative lights What? The following will tell you the main reasons for LED lamp damage:

1. The power supply voltage suddenly rises and the surge increases.

2. A component or printed circuit or other wires in the circuit are short-circuited, forming a local short circuit in the LED power supply path, which increases the voltage at this place, and the solder joints are 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 inside the lamp is too high, which deteriorates the characteristics of the LED; the temperature inside the lamp rises too fast; the temperature is too high when soldering or dipping tin.

5. Water enters the lamp, and the water is conductive. The hot air inside the closed tube accumulates to form water vapor or mist.

6. In the light source test, it is turned on and off quickly, and the charge between the electrodes is discharged (that is, it fades out when it is turned off).

7. The erosion of washing water and ultrasonic nanowaves during the washing process.

8. Live operation; all fixtures and fixtures are anti-static; keep the temperature and humidity of the environment.
