Three LED lighting national standard preparation officially launched

Posted on

Recently, the National Key Laboratory of Joint Innovation of the Ministry of Science and Technology and the State Key Laboratory of Semiconductor Lighting Joint Innovation, which was responsible for the preparation of the semiconductor lighting specification interface, was held in Beijing. In order to ensure the quality of the standard, the State Key Laboratory of Joint Innovation for Semiconductor Lighting has strengthened coordination with relevant parties, and invited key enterprises and research institutes and testing organizations of the semiconductor lighting industry to participate in the meeting and solicit opinions. The three national standards discussed in this article are "LED lighting application interface requirements: control device separation type, street lamp with self-contained cooling LED module", "LED lighting product accelerated attenuation test method 2000 hours", "LED public lighting intelligent system" Interface Application Layer Communication Protocol. Li Jintao, director of the State Key Laboratory of Semiconductor Lighting Joint Innovation, said that the support of the standard system is of great significance to the healthy development of the semiconductor lighting industry. It is hoped that relevant units will participate in the preparation of standards and jointly develop a certain technology forward-looking and expandable. The industry promotes strong national standards.
