Accelerated Life and Reliability Test of LEDs
Abstract：The lifetime and reliability of LEDs have attracted much attention in the industry, but the testing methods are challenging. Some standards on lifetime test of LEDs have been issued, however, the requirements are not the same. This paper analyzes the key aspects that influence the reliability and lifetime of LEDs, and introduces the accelerated life test method for LEDs according to the North America and International Electrotechnical Commission (IEC) standards. At last, it introduces the "Aging & Life test system for LEDs", which owns independent intellectual property rights of China and conforms to the existing standards, and can realize convenient, accurate and intelligent life test.
