The life of LED products including factors such as quality and reliability of the product, which product reliability is a key element affecting the life of the product. Reliability refers to the ability to complete the required functionality within the product specified conditions and the prescribed time. Result in poor product quality and reliability of the main reasons for the low level of design, lack of experience in hardware applications, the lack of electronic reliability of systems engineering methods and other factors. Practice has proved that the use of appropriate reliability engineering techniques to test the product.
At present, many companies in the face of intense domestic competition, but also expanding foreign markets to increase exports to European countries and the United States. The European Union and the United States introduced a number of directives and standards for mains led lights. For example, the U.S. Department of Energy and the EPA jointly issued the “Energy Star” Act, the overall LED bulb life to 25,000 hours of use but also to maintain at least 70% of the initial luminous flux. North American Lighting Association issued the LM-80-08 led high bay product standards to regulate the testing methods, how to test the product rated lumen maintenance of life “to be clearly defined. In Europe, specifically for the assessment standards for LED products are being developed, specific criteria are as follows: lighting performance requirements of standard IEC 62722-1 and IEC 62722-2-1 standard mains led lights module performance requirements of the IEC 62717, since the town stream LED bulbs performance requirements of standard IEC 62612, the LED drive performance requirements of the standard is IEC / EN 62384.
