Can the life of LED products be predicted? Xiaobian tell you, even though LED lighting with energy saving, environmental protection, long life, easy to control, maintenance-free characteristics, but ironically, we often heard the LED drive power life itself becomes a direct drag on LED lighting It does not "longevity", which greatly increases the maintenance/use cost; or the efficiency of driving the power supply is not high, so the energy conversion ratio of the LED lighting fixture is not as high as expected, or the output current ripple is not well controlled. Affecting the lighting quality, the green energy-saving advantages of LED lighting are greatly reduced, and even affect the market penetration.
Everything has a process of occurrence, development and demise. Although LEDs have a relatively long life compared to general light-emitting devices, they also have a certain life span. The early LEDs were just gifts such as flashlights and desk lamps. The time spent was not long and the life problem was not outstanding. But now LEDs have begun to be widely used in outdoor and indoor lighting, especially high-power LED street lights, which have high power, high heat, long working hours, and long life problems. In theory, it can last for 100,000 hours, but it is actually unknown. So where is the problem?
If the failure of the power supply and the drive is not considered, the life of the LED is manifested by its light decay, that is, the time is long, and the brightness becomes darker and darker until it is finally extinguished. A time of 30% attenuation is usually defined as its lifetime.
