Aging is an important guarantee of the reliability of electronic products, is a production of the last essential step. LED products can enhance the performance of aging and contribute to the late stage of the performance and stability. Solar led street lamp aging test in product quality control is a very important part, but often neglected in many cases, can not be correct and effective aging. Solar led street lamp aging test is based on the product failure rate curve of the bathtub curve characteristics and countermeasures taken, in order to improve the reliability of the product, but this method is not necessary, after all, the aging test at the expense of the life of a single LED products for the price.
Solar led street lamp aging, including the constant current aging and constant aging. The constant current source is the current constant at any time. Frequency problem, it is not constant current. It is AC or pulsating current. AC or pulse current source can be designed to be valid value is constant, but this power can not be called “constant current source. Constant current aging is most consistent with the operating characteristics of the LED current is the most scientific of the LED aging; overcurrent impact of aging is also factory using the latest means of an aging through the use of adjustable frequency, current adjustable constant current source such aging in a short period of time in order to judge the quality of the led high bay life expectancy, and can pick out a lot of conventional aging can not be singled out hidden LED.
