1. Current voltage instability, power supply voltage rise is particularly easy to cause the destruction of LED lights, the cause of sudden increase in voltage, power supply quality problems, or improper use of users and other reasons may let the power supply voltage suddenly increased.
2. The power supply path of the lamp is partially short-circuited, which is usually caused by a part of the line, or the short circuit of other wires to increase the voltage in this place.
3. It may also be that the LED is damaged due to its own quality reasons and thus forms a short circuit, and its original voltage drop is passed on to other LEDs. 4. The heat dissipation effect of the luminaire is not good, we all know that the lamp luminescence is a heat dissipation process, if the temperature inside the luminaire is too high easy to make the characteristics of the LED become bad.
This is also easy to cause damage to LED lights.
5. It is also possible that the luminaire is inside the water, because it is conductive, so it will make the lamp line short circuit. 6. Assembly time did not do a good job of anti-static work, so that the inside of the LED has been hurt by static electricity. Although the normal voltage and current values are applied, it is also extremely easy to cause damage to the LED.
