The LED Light Failure Reason
Aug 23, 2017

The LED light failure reason

Lead to LED light failure mainly have the following factors.

First, the LED product itself Quality:

1.the use of LED chip is not good, brightness attenuation faster.

2.the production process defects, LED chip cooling can not be a good export from the PIN pin, resulting in LED chip temperature is too high to increase chip attenuation.

Second, the use of conditions:

1.LED constant current drive, some LED voltage driven by the reasons for LED attenuation too fast.

2.the drive current is greater than the rated drive conditions.


Three factors that affect the quality of LED lamps

First, choose what kind of LED white light;

Second, LED lamp beads working environment temperature;

Again, LED lamp beads work electrical parameters design.
