Two Reasons Of LED Lights Weakness
Although LED lamps have improved than incandescent and fluorescent lamps, but also can not completely overcome the problem of light failure. Light failure for the LED mainly has the following two factors:
一、LED product itself quality problems
1. The quality of LED chips used is not good, brightness decay faster.
2. There is a defect in the production process. The heat dissipation of the LED chip can not be well derived from the PIN pin, which leads to the high temperature of the LED chip, which exacerbates the chip attenuation.
二、Conditions of use
1. LED is a constant current driver, some of the LED lights use voltage-driven reasons, so that the LED attenuation too fast.
2. drive current greater than the rated drive conditions.
In fact, LED products led to many reasons for the bad light, but the most critical issue is the heat. The better the heat dissipation, the lower the working temperature of LED, the smaller the light failure, the longer the LED life.
