What are the failure reasons of the LED lamps and lanterns1
LED lamps and lanterns of the failure is due to the driver and power supply failure, the second is due to the failure of LED device.
LED the failure of the device itself has the following several ways
1, the transient flow events transient flow events is to point to exceed the maximum rated current through the LED current, caused the situation of the transient flow events include LED plug, or a charged the instantaneous overcurrent when the plug.
b: LED by the impact of failure mode is not fixed, but often leads to damage of welding line. This damage is usually caused by great instantaneous overcurrent. In addition to lead to burn out welding line, can also lead to damage of close to other parts of the welding line.
2, electrostatic discharge events electrostatic discharge damage is high integration semiconductor device manufacturing, transport, and application of one of the most common transient overvoltage hazard.
LEDPN junction array performance will be reduced or damaged, ESD events caused by discharge path LED chip internal failure, the failure may only be partial function damage, serious word can also lead to LED lights article permanent damage.
