We often face many problem in using LED , but after a period of time there will be light dark light, flashing, fault, intermittent light and other phenomena, to the product Cause serious damage. This phenomenon generally causes are:
Applications, the welding process problems, such as welding soldering temperature is too high for too long, not doing the work of other anti-static, more than 95% of these problems caused by packaging processes.
Aging is an important guarantee for the reliability of electronic products, is essential for the production of the final step. LED products in aging can improve performance and help to stabilize the performance of the late stage. LED aging test in product quality control is a very important part, but often ignored in many cases, aging can not be correct and effective. LED aging test is based on the product failure rate curve of the bathtub curve characteristics of measures taken in order to improve reliability, but this method is not required, after all, the aging test at the expense of the life of single LED Products For the price.
The way of LED to age is changeable .which has a frequency problem, it is not a constant. It is AC or pulsating current. AC or pulse current source can be designed into the RMS is constant, but this power can not be called "constant current source. " Aging is the most constant LED (wholesale LED lights) current job characteristics, is the most scientific way of LED aging; over current impact of aging is a manufacturer of aging by means of the latest, through the use of adjustable frequency, adjustable constant current source of such aging To determine the LED (led panel) in a short time the quality of life expectancy, and can not pick out pick out many of the hidden dangers of aging routine LED.
