1. The voltage of the current is unstable, and the rise of the power supply voltage is particularly easy to cause the destruction of the LED lamp. There are many reasons for the sudden rise of the voltage, the quality problem of the power supply, or the improper use of the user, etc.
2. The power supply path of the lamp tube is short circuited locally, which is usually caused by the short circuit of a component in the circuit or other wires, which increases the voltage at this place.
3. It may also be that the LED is damaged due to its own quality, resulting in a short circuit, and its original voltage drop is transferred to other LEDs.
4. The heat dissipation effect of the lamp is not good. We all know that the light emission of the lamp is a process of heat dissipation. If the temperature in the lamp is too high, it is easy to deteriorate the characteristics of the LED. It is also easy to damage the LED lamp.
5. It is also possible that there is water in the lamp, because the water is conductive, which will short-circuit the circuit of the lamp.
6. During assembly, the anti-static work was not done well, so that the interior of the LED has been damaged by static electricity. Although normal voltage and current values are applied, it is also very easy to cause LED damage.
