According to the industry, LED lighting products are much more complicated than traditional lamps, covering semiconductors, lamp structures and heat sink materials, from upstream substrate materials, epitaxy, chips to device packages and applications. Covering the semiconductor industry and the lighting industry, it is an industry that integrates and integrates various disciplines. China's LED manufacturing equipment is mainly in the low-end sector, and high-end areas rely on imports. China is also in urgent need of formulating a sound industrial standard system to provide a strong impetus for the development of the industry.
The relevant person in charge of the Ministry of Industry and Information Technology said that China's semiconductor lighting comprehensive standardization aims to serve and support the development of the semiconductor lighting industry, focusing on the formulation of devices, modules, light sources and luminaire standards, and collaboratively developing epitaxial growth, chip manufacturing, device packaging, raw materials, and zero. Components, lamps, ancillary products, technical means, production preparation, inspection methods and other complete sets of system standards, the development of semiconductor lighting standards to regulate the industry, promote the healthy and sustainable development of China's semiconductor lighting industry.
According to reports, China's semiconductor lighting integrated standardization technology system is divided into three parts: general standards and materials and equipment, chips and devices, lighting equipment and systems, a total of four parts. The general standard mainly includes the terminology of semiconductor lighting, which plays a unified role in the production, circulation and standardization of products in the field of semiconductor lighting technology. The three sub-systems are divided according to the industry chain links, and each sub-system is subdivided according to the product type. 
The common specification of flat telephone cable has two core and four core, the wire diameter has 0.4 and 0.5 respectively, some areas have 0.8 and 1.0.In addition to the two and four cores, there are four, six, eight, and ten cores.
If the general family is the local telephone use mode, 2 chip is enough to use.If the telephone is used by a company or part of a group, it is recommended to use a 4-cell line in consideration of the need for telephone broadband, and a 6-cell line is recommended if a digital telephone is used.
Ministry of Industry and Information Technology officially released China's semiconductor lighting comprehensive standardization technology system
Recently, the Ministry of Industry and Information Technology officially released China's semiconductor lighting comprehensive standardization technology system, 54 standards have been issued, 73 standards are being researched and developed, and 66 standards are to be researched and developed. The standard system has reached 193 standards. item.
