On the morning of May 30, 2014, National Lighting Test Centre (NLTC) and Global Efficient Lighting Center (GELC) were selected by the National Electric Light Source Quality Supervision and Inspection Center (Beijing). The NLTC) conference hall held a press conference on the internationalization of China's LED lighting standards and the Global Efficient Lighting Forum. The theme of this conference is to open the window of the world and help China's lighting to strengthen the country's dream. The conference shared the efforts and achievements of the technical organizations including the semiconductor lighting evaluation technology alliance and the national electric light source quality inspection center to realize the dream of China's lighting power, and advocated the adoption of the domestic standard technology development platform. And the international standard promotion platform to strengthen multi-party cooperation in domestic lighting.
The conference focused on the Semiconductor Lighting Technology Evaluation Alliance (Technical Evaluation Alliance for Solid State Lighting, TEAS) and China's Semiconductor Lighting / LED Industry and Application Alliance (ChinaSolid State Lighting Industry Alliance, CSSLA) jointly released four LED lighting technology standards. Mr. Chen Yansheng, Chairman of TEAS and CSSLA, Vice Chairman and Secretary General of China Lighting Association, introduced the four standards. The standards include: safety requirements for double-ended LED lights, performance requirements, and classification and performance requirements for non-directional self-ballasted LED lamps. It is reported that the introduction of these four LED lighting technology standards will fill the standard blank of China's double-ended LED lights and LED bulbs, and improve the standard system of China's LED lighting industry. The two alliances will also continue to play the role of the industry service platform and lay a solid domestic technology and service platform for the realization of China's lighting power.
Among them, the "Non-directional self-ballasted LED lamp specification classification" standard was adopted by the IEC International Electrotechnical Commission as the IECTC34 committee document. This move has become a milestone in the classification of LED lamps, which will bring new classifications for LED lighting products worldwide. concept.
Hu Yan, inspector of the Department of Electronic Information of the Ministry of Industry and Information Technology, Deputy Director of the Energy Department of the Ministry of Finance and Economics, Mr. Ai Jun, and Deputy Director of the Department of Industry Standards of the China National Standardization Administration, Wang Li, attended the press conference. An important speech.
