The LED linear 5075 manufacturer said that everyone has such a life experience. The LED light strips just bought are always very bright, but after a period of use, the light strips will become darker and darker. What is the reason?

Lighting products, there will be a lamp failure, what is the lamp failure?
The LED linear 5075 manufacturer tells you that the light intensity of the lamp will gradually decrease after a period of use, and it cannot be restored. The reduced part is called the light decay of the LED.
The LED linear 5075 manufacturer tells you that light decay generally refers to its luminous flux. When the surface of the photosensitive drum is charged, as the charge accumulates on the surface of the photosensitive drum, the potential continues to rise, and finally reaches the "saturation" potential, which is the highest potential. The surface potential will decrease over time. Generally, the working potential is lower than this potential. This process of natural decrease in potential over time is called the "dark decay" process. The LED linear 5075 manufacturer tells you that when the photosensitive drum is scanned and exposed, the dark area (referring to the surface of the photoconductor that is not illuminated by light) is still in the dark decay process; The current density increases rapidly, the conductivity rises rapidly, forming a photoconductor voltage, the charge quickly disappears, and the surface potential of the photoconductor also drops rapidly. It is called "light decay", and finally slows down.
The LED linear 5075 manufacturer tells you that the general LED lamp strip packaging manufacturer does the test under laboratory conditions (at a normal temperature of 25°C), and continuously lights the LED for 1000 hours with 20MA direct current to compare the light intensity before and after lighting.
Calculation method of light decay:
Luminous decay in N hours = 1-(Luminous flux in N hours / Luminous flux in 0 hours)
The longer the LED light strip is used, the darker it will be, because the LED light strip will have the phenomenon of light decay.
The LED linear 5075 manufacturer tells you that the current light decay degree of the light strip products made by various manufacturers is different. High-power LED light strips usually have light decay, which is directly related to the temperature generated during the use of the light strip. , Is mainly determined by the chip, phosphor, packaging and so on.
