1. The voltage of the LED light current of the light -emitting diode is unstable. The increased supply voltage increase is particularly easy to cause the destruction of LED lights. There are many reasons for the sudden increase in voltage. The power supply voltage suddenly rose.

  2. The local short circuit of the power supply channel of the lamp tube is usually caused by a part of the line, or the short circuit of other wires to increase the voltage of this place.

      3. It may also be that the LED is short -circuited due to its own mass damage. Its original voltage drop is passed on to other LEDs.

      4. The heat dissipation effect of the lamp is not good. We all know that the glowing of the lamp is a process of heat dissipation. If the temperature in the lamp is too high, it will easily deteriorate the characteristics of the LED. This is also easy to cause damage to LED lights.

      5. It may also be water in the lamp, because the water is conductive, so that the lines of the lamp will be short -circuited.

      6. During the assembly, I did not do a good job of anti -static work, causing the interior of the LED to be damaged by static electricity. Although the normal voltage and current value is applied, it is also easy to cause LED damage.
