The main influencing factors of LED light decay

The main influencing factors of LED light decay

1.The Chip

Due to wafer itself in the process of photoelectric conversion is a continuous consumption, continuous attenuation process, so the Chip delay of different material of the Chip are totally different.

2.Junction temperature

Junction temperature is the main factor of influencing LED light decline. LED temperature rise will greatly accelerate LED light decline. Therefore once we make a large current to increase the luminous flux, it will accelerate the LED decay rate.

3.Fluorescent powder

For white light products, phosphors have it’s own decay period. During the LED lighting process, the phosphors is in the excitation state at the early period, so the luminous flux increases, and then the phosphor enters the decay cycle.
