Causes of dimming of LED ceiling lights

The chosen LED chip has poor material quality and fast brightness attenuation.Leds have generally normal light attenuation, use for a long time will become dark, generally within a year of 5% is normal, 15% in three years, so the led May 10 years later, you can also use the luminous flux decreases a lot, however, less driving power, the output current is low, will cause the distribution to the led current is reduced, dimming, then suggest the light changed, and the original led and drive power does not match.The drive output current exceeds the maximum current that the LED ceiling lamp can withstand. After a long time, the light attenuation will be very serious, which will lead to dimming
