Why LED lights become darker as they are used

LED lights become darker as they are used because LED lights have light decay phenomenon.

LED light attenuation means that after a period of time when the LED is lit, its light intensity will be lower than the initial light intensity and cannot be recovered, that is, the reduced part is called the LED light attenuation. The light decay of LED lamp products is the weakening of the light signal during transmission. At this stage, LED products made by major global LED manufacturers have different degrees of luminous decay. High-power LEDs also have luminous decay, which is directly related to temperature. It is determined by the chip, phosphor and packaging technology.

Ningbo ZEHAI lighting Co., LTD is a company engaged in design, development, manufacture, and marketing of LED lighting fixtures and solar lighting products with first-class technology.
