May 12, 2017 National Standard Committee issued the national standard of the People's Republic of China announcement 2017 11th, of by semiconductor lighting combined with innovation state key room took the lead in the preparation of the national standard GB/T 33720- 2017 'accelerated test method for luminous flux attenuation of LED lighting products' was released and will be implemented in December 1, 2017. GB/T 33720- 2017 'accelerated test method of LED lighting product's luminous flux attenuation' is the transformation of the results of the general research project of semiconductor lighting product's reliability accelerated test and analysis in the State Key Laboratory of semiconductor lighting joint innovation, A set of feasible and reasonable detection methods is provided for quickly and effectively judging the luminous flux attenuation characteristics of LED lighting products, on the premise of not affecting the accuracy of reliability evaluation, the traditional test time of 6000h is shortened to less than 2000 h, and the color stability of LED lighting products, and other subsystems such as power drive, heat dissipation structure and secondary optical design have established basic reliability requirements, which can be widely applied to most indoor LED lighting lamps, road lighting lamps and special lighting lamps in the market. This standard saves a lot of testing time for LED lighting enterprises in China, and is of great significance for reducing the research and development cycle and cost of enterprises and accelerating the development of LED lighting industry.
