At the press conference, the results of 21 technical specifications for LED lighting standard components in Guangdong Province were released. The Guangdong Provincial Department of Science and Technology will fully implement the "LED Lighting Standard Optical Component Plan", promote the connection between the standard optical component project and the standard system construction, start the preparation of the local standard series of LED lighting products, and take the lead in establishing a relatively complete LED product standard system in the country. At the same time, actively participate in the formulation of national standards for LED products.
The first batch of 21 optical component standards, standardizing the LED lighting market
At the meeting, Director of the Joint Innovation Center of Guangdong Semiconductor Lighting Industry, Mr. Yan Shirong, issued 21 technical specifications for LED lighting standard optical components, and explained in detail the LED lighting standard optical component promotion program.
It is understood that since the May 28, 2012 Guangdong LED lighting application promotion work conference was held, Guangdong Province has set off a wave of comprehensive promotion and implementation of LED lighting products. However, most of the "components" of LED lighting products exist in a non-standardized form. The lack of standards leads to the lack of data design, poor product interchangeability, and poor compatibility, which hinders the large-scale application and industrial development of products. To this end, Guangdong Province relies on the successful experience of the benchmarking system to accelerate the implementation of the LED lighting standard optical component program. After half a year, after in-depth market research, starting from the bottom of the enterprise, starting from the bottom up, under the joint research and joint efforts of more than 50 scientific research institutions, colleges and leading enterprises, the first 21 optical component standard specifications were developed. After a few days of closed-door meetings of the expert group, the LED lighting standard optical component specification system was officially completed.
In order to let the participants better understand the norms and application norms, the leader of the optical component expert group and the professor of Zhongshan University, Wang Gang, introduced the framework and key points of the LED lighting standard optical component specification system. According to Professor Wang, the technical specifications mainly cover the general specification, the package component sub-specification for certification, the illumination mode component specification, the illumination source specification, the integrated luminaire specification and the test method. Among them, the specification of the lighting module is divided into detailed blank specification for lighting modules such as street lamps, tunnel lights, downlights, spotlights, lamps and street lamp tunnel lights. This standard optical component specification defines the terms and definitions, classification and coding, mechanical description, limit values ​​(absolute maximum ratings), working range and photoelectric characteristics of the relevant levels in detail, with clear content and professionalism. It is very instructive and practical for enterprise production.
Teamwork and efforts to promote the standard optical component specification
At the meeting, Dehao Runda Vice President Yan Xiaoming, Qin Shang Optoelectronics R&D Director Huang Jinbo and Jingke Electronics Dr. Sun Jiaxin gave speeches on the promotion and application of standard optical components as corporate representatives, which caused strong repercussions. LED lighting companies such as Qinshang Optoelectronics, Guoxing Optoelectronics, Hongli Optoelectronics, Foshan Lighting, NVC Lighting, Op Lighting, Lehman Optoelectronics, Chau Ming Technology, Jufei Optoelectronics, Ruifeng Optoelectronics, Moso Power, and Mu Linsen The development of standard optical component specifications and the improvement of the LED lighting standard system have contributed to the further development of the LED lighting industry in Guangdong Province.
In order to further improve the technical specifications of LED lighting standard optical components and promote the standard optical component specification, the conference also arranged the optical component group training and Q&A sessions. The optical component experts conducted detailed training and guidance on the optical component specification system framework, optical component hierarchy, and optical component test specifications.
Exploring practice and striving for the experimental field of national standardization work
The LED lighting industry is one of the three major breakthroughs in the development of strategic emerging industries in the “Twelfth Five-Year Plan†of Guangdong Province, and the industry is developing very rapidly. According to statistics, in 2012, the LED industry in Guangdong Province exceeded 200 billion yuan, and the LED lighting engineering transformation was fully promoted. The LED street lamps reached 780,000 baht and the indoor lighting renovation exceeded 1.2 million baht.
In order to promote the popularization of LED lighting, the Guangdong Provincial Department of Science and Technology under the correct leadership of the provincial party committee and the provincial government, vigorously implement the industry standard strategy, fully promote the standardization of the LED industry, enhance the core competitiveness of the industry, and lead the standardization work. National. Director of the National Standards Commission Chen Gang and the provincial governor Chen Yunxian successively inspected the Guangdong Provincial Science and Technology Department and the Provincial Semiconductor Lighting Joint Innovation Center to conduct research on the standard optical component project. While highly appreciating the project, the standard light was requested as soon as possible. Component projects are built to national standards.
The release of the standard specification of LED lighting standard optical components marks that Guangdong Province has taken a solid step in the standardization of LED industry, laying a theoretical foundation for the development of the standard optical components from de facto standards and industry standards to national standards and international standards. Basis and practice basis, also for the Chinese LED lighting industry to win the international right to seize the opportunity. Ye Jingtu, deputy director of the Science and Technology Department of Guangdong Province, believes that as the optical component project enters a tough stage, the standard problems that plague the LED industry in China are expected to be solved. The popularization and promotion of LED lighting products will also set off a new climax. 
jumper (Optical Fiber Patch Cord/Cable) and coaxial Cable are similar, but no mesh shielding layer. The center is the spread of light glass core. In multimode optical fiber core diameter is 50 microns to 65 microns,
roughly the comparative with the thickness of a human hair. And the diameter of the singlemode fiber core is 8 microns to 10 microns. Core surrounded by a layer of refractive index is lower than the core glass envelope, to make the optical fiber to keep within the core. Outside is a thin layer of a plastic coat again, to protect the sleeve.
On January 25th, Guangdong Province “LED Standard Light Component Work Report and Technical Meeting†was held in Guangzhou Science Center. At the meeting, the phased results of the optical component project research were officially announced—21 LED standard optical component series normative documents, which made a solid step for further standardizing the LED application market and solving the industrial development problem.
