6 major causes of LED lamp damage
The white LED is a voltage-sensitive device. In actual operation, the current is 20 mA. However, the current may increase due to various reasons in use. If no protection is taken, this increased current will increase the current. LED will be damaged after a certain amount of time and time
1, the sudden increase in power supply voltage.
2. Short circuit of a component or printed line or other wire in the circuit creates a local short circuit in the LED power supply path, which increases the voltage at this place.
3. A certain LED is damaged due to its own quality and thus forms a short circuit, and its original voltage drop is passed on to other LEDs.
4, the temperature inside the lamp is too high, so that the characteristics of the LED deterioration.
5, the water inside the lamp is water, the water is conductive.
6. The anti-static work was not done during assembly, so that the interior of the LED has been damaged by static electricity. Although the normal voltage and current values ​​are applied, it is very easy to cause damage to the LED.
