According to the “Notice of the First Batch of Electronic Industry Standard Scientific Research Projects of the Ministry of Information Industry in 2007 (Xinke Han [2007] No. 21)â€, the Semiconductor Lighting Technical Standards Working Group (hereinafter referred to as the “Standard Working Groupâ€) is responsible for drafting 7 electronic products. Industry standards (see the attached table for the project name and main contractor).
After more than a year of hard work, the project organizers drafted draft standards and solicited opinions in the standard working group. Some of the standards also sought opinions in the “National Semiconductor Lighting Engineering R&D and Industry Alliance Establishment Standardization Coordination Promotion Working Groupâ€. The project organizers revised the standards according to the feedback opinions, completed the standard drafts and related materials, and publicized them on the website of China Electronics Industry Standardization Technical Association to solicit opinions from all sectors of the society. After the end of the publicity period, no feedback was received from the China Electronics Industry Standardization Technical Association.
According to the relevant procedures established by the electronic industry standards, in late September, we organized relevant experts in the industry and held a standard validation meeting in Guiyang to review the seven standards. The meeting experts carefully and carefully reviewed the standards and made the following conclusions:
※ The standard preparation has fulfilled the relevant procedures for the preparation of electronic industry standards, and the documents for review are provided.
※ The standard is in accordance with the relevant provisions of the national standard GB/T1.1-2000 "Standardization Work Guide Unit 1: Standard Drafting and Expression Rules Part 1: Basic Rules for Standard Preparation".
※ The technical content of the standard is in line with the actual development of China and the direction of science and technology; the technical regulations are advanced, safe, reliable, economic and reasonable; in line with China's laws, regulations and policies, it can be harmonized with relevant national standards, industry standards and standards at the same level.
The meeting experts also put forward some amendments and suggestions on these seven standards.
The meeting unanimously agreed to pass the validation of these seven standards. After the meeting, the standard preparation team will further modify and improve the draft for review according to the spirit of the meeting, and form the standard approval draft and its approval and report to the relevant departments.
The formulation of these seven standards has played a major role in the standard system of the sub-sector 2 (mainly including LED chips, LED devices, LED modules/components in the mid-chain of the industrial chain), and has played a role in promoting industrial development. Promote the role and play a certain guarantee role in regulating the market. At the same time, these seven standards also cover the upstream materials of the industry: substrate sheets and phosphors. The following is a brief introduction to these seven criteria:
1. Semiconductor lighting terminology: includes basic terms related to semiconductor lighting, optical measurement terminology, color measurement terminology, thermoelectric measurement terminology, epitaxy, chip, package and partial lighting application product terms and definitions, with more than 140 terms. The standard also sought the opinions of Taiwan through the platform of the "Straits Cross-Strait Information Industry Technical Standards Forum" and compiled the draft "Semiconductor Lighting Terminology for Lighting Tables".
2. Sapphire substrate for GaN-based light-emitting diodes: The parameters, test methods, geometric dimensions, test methods, and quality assurance regulations for sapphire substrate sheets for gallium nitride-based light-emitting diodes are specified.
3. Phosphors for semiconductor light-emitting diodes: The performance requirements, test methods, inspection rules and signs, packaging, transportation, storage, etc. of phosphors for white light-emitting diodes are specified. The standard includes 5 grades of aluminate phosphors and 7 grades of silicate phosphors. For the newer nitride phosphors, the technology and production will be greatly improved. .
