What are the main reasons for Truck LED damage?
Truck LED rear tail lights are voltage-sensitive devices. In actual work, the current limit is 20mA, but the current often increases due to various reasons in use. If no protective measures are taken, this increase The LED will be damaged after the current exceeds a certain time and amplitude. So what are the main reasons for LED damage:
①The power supply voltage of the LED rear tail light of the truck suddenly increases.
②The short circuit of a component or printed line or other wires in the circuit forms a partial short circuit of the LED power supply path, which increases the voltage in this place.
③A certain LED is damaged due to its own quality and thus forms a short circuit, and its original voltage drop is transferred to other LEDs.
④ The temperature in the lamp is too high, which will deteriorate the characteristics of the LED.
⑤ Water has entered the interior of the LED rear tail light fixture of the truck, and the water is conductive.
⑥ The anti-static work was not done well during assembly, so that the interior of the truck's LED rear tail light has been damaged by static electricity. Although normal voltage and current values are applied, it is very easy to cause damage to the LED.
