LED lights are voltage-sensitive devices. In actual work, the upper limit is 20mA current, but in use, the current tends to increase due to various reasons. If no protective measures are taken, the increased current will damage the LED after a certain time and magnitude.
The main reasons for LED damage are:
1. The power supply voltage rises suddenly.
2. The local short circuit of the LED power supply path is due to the short circuit of a component or printed circuit or other wires in the circuit, which increases the voltage in this place.
3. An LED is short-circuited due to its own quality damage, and its original voltage drop is transmitted to other LEDs.
4. The temperature inside the lamp is too high, which makes the characteristics of the LED worse.
5. There is water in the lamp, and water is conductive.
6. The anti-static work is not done well during assembly, which causes the interior of the LED to be damaged by static electricity. Although normal voltage and current values are applied, it is easy to cause LED damage.
