The company's electromagnetic noise suppression sheet series products are made of micron flake alloy soft magnetic powder and polymer mixed, dispersed and pressed, with excellent electromagnetic noise suppression function.

In order to deeply understand the production capacity recovery of various manufacturers under the epidemic situation, exchange and discuss the future development trend and Countermeasures of LED lighting product technology and market, on April 1, the optoelectronic device Professional Committee of China Lighting Appliance Association and the Talent Training Committee of China Lighting Appliance Association jointly hosted the "2020 cloud Salon of optoelectronic device Professional Committee of China Lighting Appliance Association to deal with the epidemic situation", OSRAM optoelectronic semiconductor (China) Co., Ltd., Seoul Semiconductor Co., Ltd., Fujian tiandian optoelectronic Co., Ltd., Samsung led China, Kota lighting (Shanghai) Co., Ltd. and Chengdu hengkun Optoelectronic Technology Co., Ltd., six representatives of key optoelectronic and electrical parts enterprises at home and abroad, shared online relevant information on the capacity recovery of manufacturers under the epidemic situation, the main problems encountered at present and the subsequent market judgment.Chen Yansheng, President of China Lighting Appliance Association, said in his concluding speech that at present, the whole industry is under pressure from both sides of production and market demand. Crisis and opportunity coexist. People-oriented healthy lighting has been developed, which is also the future development direction of the industry. At the same time, he called on lighting enterprises to provide more industry information and reasonable suggestions to the government. He said that the association will help enterprises communicate with the government, which is also conducive to the introduction of more policies beneficial to the industry.According to Wen Qidong, Deputy Secretary General of China Lighting Appliance Association, with the stable control of the epidemic situation in China, enterprises in various industries have returned to work one after another. For the lighting industry, it is difficult for manufacturers to return to work caused by insufficient epidemic prevention supplies, low workers' recovery power and poor logistics and transportation. At the same time, because China has a complete lighting industry chain, it has little impact on production capacity. However, in terms of funds and orders that affect the core of industrial development, with the development of the global epidemic, there will be a wave of reserve demand for products in the short term, but in the long run, it will enter a period of weak development. Wen Qidong said that lighting manufacturers will face a comprehensive test of management, operation capacity and various reserves.In this response to the epidemic situation, backbone optical and electrical equipment enterprises at home and abroad also shared their experience. The reporter found that these industries invariably allocate production resources to various sectors, and develop from simple lighting to new optoelectronic applications such as plant lighting, human factor lighting, unmanned driving, face recognition and contour recognition. At the same time, seek the development of UVC LED industry brought about by the strong demand of consumers for air purification, water purification treatment and object surface sterilization, as well as the development of human factor lighting and other health lighting driven by the light required by indoor human body for a long time.The light efficiency of UVC LED is still too low, just like the ordinary lighting LED 15 years ago and 10 years ago. The light source lamps are still traditional products, which will have cost performance, but in the next 3-5 years, UVC LED will have the opportunity to catch up. " At the same time, he said that with the large-scale popularization of global and Chinese manufacturers, the manufacturing cost of a single device has been reduced and the efficiency has been improved. "Only when our LED devices and core optoelectronic devices are done well can we have a better system." Wu Sen, vice president of the market of Seoul Peninsula Co., Ltd., also said that at present, the chip was less affected by the epidemic because it had a high inventory before. However, the beginning of the second quarter will usher in extremely weak demand, The impact has affected all LED Applications (vehicle, display and lighting). At the same time, health lighting has ushered in a wave of upsurge and UV demand. "Small and medium power traditional lighting applications are mainly used for indoor and outdoor lighting. Due to the impact of the epidemic, the replacement and new demand for lighting will inevitably decrease in a certain period of time. However, for the current stage, customers need to prepare a certain amount of inventory, so there will be a peak order period in the short term." Wusen analyzed. Qiu Zhengkang, executive vice president of Fujian tiandian optoelectronics Co., Ltd., also shared the measures taken by enterprises to deal with the epidemic. He said that under the bad situation of the optoelectronics industry in the short term, tiandian optoelectronics plans to shrink various product models, focus on the production and storage of popular models, and use the boom gap to advance the layout of products such as optical sensing and IC packaging, In response to the huge domestic and external demand when the economic recovery comes.

A new round of digital city planning and construction is in full swing throughout the country. In the tide of digital city construction, as the main force of new information infrastructure, operators take 5g as an opportunity to promote network transformation, actively promote the integrated development of business, network and ecology, and explore the road of digital transformation in the era of smart city. Recently, in the bidding of "2021 digital city intelligent analysis and artificial intelligence platform modeling technology service project" held by China Telecom Baoding Branch, shadow spectrum technology, a leading enterprise in the field of artificial intelligence in China, successfully won tens of millions of orders with its technical advantages and comprehensive strength.In the project, shadow spectrum technology will rely on its core technical advantages in the fields of AI twinning and digital upgrading to provide China Telecom with technical services such as structural analysis of AI virtual digital twinning system and intelligent system platform of digital city, and help the construction of digital city and artificial intelligence platform with scientific and technological innovation.In recent years, China Telecom has actively implemented the responsibility mission of building a network power, digital China and maintaining the main force of network information security, and made great efforts to build a service-oriented, scientific and technological and security enterprise. Under the guidance of China Telecom Group's "cloud to digital transformation" strategy, Baoding Branch of China Telecom Group continues to accelerate business transformation, actively follow up industrial transformation, promote the process of "integration of industrial digitization and digital industrialization", lead new infrastructure construction with 5g, and serve urban digital upgrading and high-quality development.Digital twin system is the foundation of digital city and the prerequisite and strategic preparation for any city to enter digital city. As an AI image production infrastructure and service provider, shadow spectrum technology took the lead in launching AI + DT deep integration AI digital twin engine ADT, which deeply covers multi industry scenarios, promotes the extensive link of intelligent image technology to industrial clusters, and enables the digital upgrading of national key industries. AI digital twin engine of shadow spectrum technology will help China Telecom Baoding Branch's digital process, so as to increase the value of data and information, make physical cities and digital cities "grow together", and make the city operation smarter and smarter.According to the 2020 digital twin white paper led by the Ministry of industry and information technology, by 2023, the market scale of China's new smart city will reach 1.3 trillion yuan. The huge market space not only attracts many enterprises to join the Bureau, but also makes the construction of digital city enter the fast lane of development. With the support of new technologies and new industrial forms, the digital city developed on the "new infrastructure" is a huge industrial cluster, which will enter the "second half" of interactive connection, system integration and ecological integration.
