“Guangdong is at the forefront of reform and opening up, and the vitality of scientific research and innovation is vibrant. It is the greatest affirmation of team work to be able to win this honor!†Tang Yong, a professor at South China University of Technology, was excited to win the first prize of the 2017 Guangdong Science and Technology Award. Say. From the sparkling machinery manufacturing workshop, step into the LED precision manufacturing laboratory. In the past 8 years, Tang Yong has concentrated on the core technology grafting and research and development, and created the world's smallest record of 0.25 square millimeters of mass-produced LED display devices. At present, the scale of Guangdong LED industry ranks first in the country, and LED device packaging accounts for about 70% of the country. The products are sold overseas and occupy half of the international market. Tang Yong and his team have contributed. A few days ago, Tang Yong was interviewed to tell his innovative story from the traditional industry to the cutting edge of technology. Industry, university and research deep integration core technology to help Guangdong enterprises climb to the top "In the beginning, companies didn't believe that I could help them, but I just wanted to do it." Tang Yong said. Light-emitting diodes are referred to as LEDs, which convert electrical energy into light energy. Today, LED streets are indispensable for urban streets, celebrations, and daily households. However, eight years ago, when the industry started, the performance of LEDs was unstable, the heat was severe, and mass production was nowhere in sight. These problems are not solved and LEDs cannot produce practical benefits. Tang Yong inquired about the needs of enterprises and wanted to enter this emerging industry with his mature electronic thermal control technology. In order to dispel corporate concerns, Tang Yong immediately invested in research. He found that the LED devices produced by internationally renowned manufacturers have a process of vaporization deposition of a heat-resistant transition substrate, which is difficult, costly and compromised in quality. From the point of view of his own machining, he has pioneered the transition substrate thinning process, soldering the heat-resistant ceramic directly to the device, and then grinding and thinning. This kind of technicians think that the "inconceivable" approach unexpectedly saves the cost of preparation and improves the quality of the product. Tang Yong and the team’s reputation have been hit, and core technologies and new industries have sparked. At present, the industrial scale of device packaging enterprises in Guangdong ranks first in the country, with output accounting for 70% of the country and 50% of the world. Among them, Tang Yong and his team contributed. In the three years from 2014 to 2016, they have accumulated nearly 16 billion yuan in sales for the cooperative enterprises, with new profits of 1.582 billion yuan. “The first step in enterprise demand is the secret of scientific success.†Tang Yong said that their team is really taking a new road of integration of production, study and research. Every year, students are sent to take root, and he guides students’ professionalism. The papers are also closely related to the actual experience of enterprise production, industry and academic research with the same frequency resonance. High-value-added field products maintain world record Foshan Lighting and Sanxiong Aurora are two brands of lamps that consumers are familiar with. Tang Yong said that each of the lamps produced by the two companies has their technical team behind them. In the Chinese lighting industry, the sales revenue of the above two enterprises' lighting products accounted for 1/4 of the total receivables of listed companies in the scale of 100 million yuan, establishing the leading position of the LED lighting industry in Guangdong Province. "The first generation of LEDs solves the problem that can not be used. After the replacement, it is necessary to invest in high value-added fields." Tang Yong introduced that, in the display field such as LCD rear projection, the profit rate is twice as high as that of lighting products. the above. The display puts higher demands on the light-emitting efficiency and light color accuracy of the LED device. If the spectral accuracy is not enough, the light color display effect will be deviated. Tang Yong's key technology project for designing and manufacturing trans-scale optical functional structures of semiconductor light-emitting devices has solved the problem of accurate light-emitting of LED devices and reduced the loss of light propagation process. With the technical support of the Tang Yong team, the luminous efficiency index of the LED devices produced by the cooperative enterprises is 32.29% higher than that of the industry benchmarking company Cree, and the lighting efficacy of the lamps has also increased by 21.84%. "0.5 mm square, in the space where the naked eye is very ugly, you must also seal at least 4 light source interfaces." Tang Yong pointed to an LED device told reporters. This device is produced by Foshan Guoxing Optoelectronics under the technical support of Tang Yong team. The company not only ranks first in the world in terms of LED package production, but also maintains the world's smallest record size for mass-produced display devices in 0.5 x 0.5 (mm). The LED display assembled by this device was selected as the 70th anniversary parade of the Anti-Japanese War, the G20 Hangzhou Summit, and the Rio Olympic Games service, demonstrating the innovation power of Guangdong on the world stage. Participate in the development of international standard service areas and expand to satellite positioning Up to now, the core technology of the Tang Yong team has been authorized to invent 31 patents and 2 computer software copyrights. It is worth noting that the field of project design has formed a complete patent system. In 2017, South China University of Technology, as a representative of domestic universities, and the joint development of the international technical standard IECQ OD3803, became the main setter of the first LED component specification in China, showing a strong Guangdong innovation hard power. The technical contribution of the Tang Yong team has enabled the Guangdong LED industry to expand from general lighting to high value-added display, leading the country. He said: "I can't stop, there is no end to innovation." Today, the vents are coming again. Driverless technology has become the new darling of technology companies and car manufacturing companies. While trying to take the lead in occupying the market, security has become the biggest difficulty to overcome. "The key technology of the third generation of LED industry lies in the application of optical communication positioning. The promotion of this application will truly realize safe unmanned driving." Tang Yong believes that if the unmanned vehicle is equipped with optical communication equipment, the positioning will reach At the meter level, the driving equipment can be accurately positioned to absolute coordinates, and the safety performance is greatly improved. Behind the small LED is a huge industry. After the idea was opened, Tang Yong is currently negotiating cooperation with agricultural enterprises to develop eco-cultured LED equipment. At the same time, it actively serves the national strategic industry and develops high-precision optical communication equipment for satellite positioning. 118 size switch socket, wall switch socket, freedom switch socket Guangdong Shunde Langzhi Trading CO., Ltd , https://www.langzhielectrical.com
