Factors Contributing To LED Light Failure

Mar 04, 2017

1.LED product quality problems of its own:
1) using the poor health of the LED chip, rapid brightness degradation.
2) production shortcomings, LED chip cooling export not good from a PIN the feet, lead to excessive temperature of the LED chip and chip attenuation.

2. use conditions:
1) LED constant current driver, some LED attenuation LED voltage-driven reasons too quickly.
2) drive current is greater than the rating of the driving conditions.
