LED燈損壞原因
瀏覽:228 發布日期:2017-05-04
1. current voltage instability, voltage increase is particularly likely to cause LED light damage, many reasons for a sudden rise in voltage, power quality problems, improper use and other reasons or the user may allow the power supply voltage is suddenly increased.
The short circuit of the power supply path of the 2. lamp tube causes the voltage in this region to be increased by a short circuit in the circuit or a short circuit of other wires.
3., it is also possible that LED is damaged due to its own quality, thus forming a short circuit, and its original voltage drop is shifted to other LED.
4., the cooling effect of the lamp is not good, we all know that the tube light is a heat dissipation process, if the lamp inside the temperature is too high, it is easy to make the characteristics of LED worse. This can also cause damage to the LED light.
5., there may be lights inside the water, because the water is conductive, so that it will short-circuit the wiring of the lamp.
6., when the assembly is not done anti-static work, so that the internal LED has been damaged by static electricity. Although the normal voltage and current value are applied, it is also easy to cause damage to LED.
