Why is the led light not as bright as it was at first when it was used for a long time?

Today Jie a small series for you to bring the reason to share. In fact, many people will find that the led black line lamp is not as bright as before after a long time, which is explained by the professional vocabulary of the lighting industry-light decay. Light decay is a physical phenomenon, for lamps and lanterns is an unavoidable problem, from the beginning of the incandescent lamp, it is obvious that the loss of tungsten wire, the lamp is getting darker and darker, it is obvious that the light decay, just like birth, old age, sickness and death, lamps and lanterns also have the same life. In actual use, led black line lamps may last far more than 6 hours, and in the process of installation, installers often hope to save installation time and convenience. When the lamps are not installed according to the number of LED line lamps known by the manufacturer, the number of lamps connected in series is often overloaded, resulting in unstable voltage and current of LED line lamps and other behaviors that seriously damage the life of LED line lamps. Incorrect use of these methods will also speed up the light decay time, so light decay cannot be calculated simply by addition, subtraction, multiplication and division. Therefore, it is normal for led lights to be used for a long time and not as bright as at the beginning, but it is also important to choose good quality led line lights and correct usage methods. Do not increase the number of LED line lights in series in order to save materials, resulting in voltage and current instability and other behaviors that damage the life of lamps. Normally, it is no problem for led line lights to be used for 2-3 years. Jieyi Electric was established in 1996 and is located in the famous manufacturing capital-Dongguan.
