What is the cause of the damage of the LED lamp holder

as new green lighting technology, high-power LED lamps and lanterns with high optical conversion efficiency, low energy consumption, long service life, no maintenance etc, gradually be applied to all kinds of lighting category. High-power LED short-lived life is based on the working environment of peace, on high power high power LED lamps and lanterns, there are two main coerce influence its life expectancy:

1. Maximum impact damage to the LED lamp holder:

high power high power LED lamps and lanterns is imposed on the current is over the high power LED lamps and lanterns of maximum rated current technical data sheet, including over-voltage provoked the CLP impact; Another kind is overheating damage. These damage can show the device immediately fails, may also attack in current shock things after a long time before failure, shorten the working life of the high power LED lamps and lanterns.

2. High power LED lamps and lanterns is damage to the LED lamp holder:

the power of the high power LED lamps and lanterns and usually driven impact damage from the input power of the CLP ( EOS） And the open circuit fault on load. CLP impact of input power supply is often formed in the drive circuit driver chip damage, broken down and capacitance passive components such as attack. Load side short-circuit faults may be the over current drive of drive circuit, drive circuit may attack damage of short circuit or short circuit fault cause damage of overheating.
