LED light failure causes:
A, LED product itself quality problems:
1, LED chips good body, brightness decreases rapidly.
2, the production process is defective, LED chip cooling is not good exported from the PIN feet, causing the LED chip temperature is too high to make the chip attenuation intensified.
Second, conditions of the problem:
1, LED constant current driver, voltage-driven part of the LED, the LED attenuation over.
2, the drive current is greater than the rated drive conditions.
Three affect the quality of LED lamps light attenuation factors:
1, choose what kind of LED white light;
2, LED lamp beads working environment temperature;
3, LED lamp beads electrical parameters of the design work
