SCUT Professor Award, help Guangdong LED industrial scale topped the country

"Guangdong is located in the forefront of reform and opening up, innovation vitality full of vigour. To receive this award, is certainly the biggest team work!" South China University of Technology professor Tang Yong said excitedly in the 2017 Guangdong provincial science and technology award first prize.

The mechanical manufacturing workshop from sparks, stepped into the LED precision manufacturing laboratory. 8 years, Tang Yong concentrated core technology grafting and development, created the smallest world record production LED display 0.25 mm.

At present, Guangdong LED industry ranked first in the country, LED package volume accounted for about 70%, the products are exported to overseas, occupy the international market half of the sky. Tang Yong and his team contributed. The day before, Tang Yong interview, tells him to the frontier science and technology from the traditional industry innovation story.

The depth of integration of core technology help Guangdong enterprises Summit

"At the beginning, companies do not believe that I can help them, but I just want to do this." Tang Yong said.

The light emitting diode LED, the semiconductor electronic components can be converted to electrical energy. Now, the city streets, to celebrate the occasion and household are not the figure of LED. But in 8 years ago, when the industry started, LED's performance is not stable, serious heat production in sight.

These problems are not resolved, LED is unable to produce the actual benefits. Tang Yong heard the demand of the enterprise, want to rely on the electronic thermal mature control technology, in this emerging industry.

In order to dispel the concerns of business, Tang Yong immediately put into research. He found that the international well-known manufacturers of preparation process of LED device has a heat-resistant substrate vaporization deposition of transition, difficult process, high cost, quality and discount. He started from his old job machining angle, another way to create transition substrate thinning process, the heat resistant ceramic soldered directly to the device, and then grinding thinning. The technical personnel that "fantastic" approach is beyond all expectations to save the preparation cost, make the product quality improvement.

A famous Tang Yong and team started, core technology and new industrial sparks. At present, Guangdong packaging industry scale of production ranked first in the country, accounting for about 70% of the country, 50% of the world. Among them, Tang Yong and his team contributed. In 2016 2014 - three years, they have accumulated nearly 16 billion yuan in sales for the cooperative enterprises, the new profit of 1 billion 582 million yuan.

"To the enterprise demand for the first, this is the secret of success of scientific research." Tang Yong said that their team is really out of a new road to research deeply into cooperation, to send students to take root enterprises every year, experience who guided the students of professional papers are all closely linked to production, industry and academic research with the resonance frequency.

Keep the world record high added value of the force field of product

FSL is the two and three male Aurora consumers are familiar with the brand lamps. Tang Yong said that each of the two lamps of enterprise production, they are behind the technical team.

In the China lighting industry, lighting products sales revenue of enterprises accounted for the two billion yuan scale of listed companies accounts receivable sum 1/4, established in Guangdong Province, LED lighting industry leading position.

"The first generation of LED is that it can not resolve the problem, after upgrading to high added value to the field of force." Tang Yong introduced, such as LCD rear projection display field, profit margins than lighting products more than doubled.

The display of the LED device light efficiency and light color accuracy are put forward higher requirements. If the spectral accuracy is not enough, there is deviation display color. Tang Yong presided over the semiconductor light emitting device cross scale optical functional structure design and manufacturing technology key project is an excellent solution to the LED device accurate light problem, reduce the loss of light propagation process.

Tang Yong team in support of technology, light efficiency index LED device production cooperative enterprises, 32.29% higher than the industry benchmark for companies produced by the United States CREE device, the light efficiency of this one is increased by 21.84%.

0.5 mm square, it is difficult to see the naked eye in space, but also into at least 4 light source interface." Tang Yong pointed to a LED device told reporters.

This device is in the Tang Yong team supported by Foshan nationstar optoelectronics production. The company not only in the LED packaging production ranks first in the world, 0.5 * 0.5 (mm) also maintained a minimum world record production display size. By this device assembled LED display production, was selected to serve the 70th anniversary victory parade, the G20 summit in Hangzhou, the Rio Olympics, showing the Guangdong innovation force on the world stage.

Participation in the formulation of international standards of service to expand the area of satellite positioning

As of now, the core technology of Tang Yong team 31 authorized patents, 2 computer software copyrights. It is worth noting that the project design field has formed a complete system of patent.

In 2017, South China University of Technology as the representative of the college, combined with international technical standards laboratory IECQ OD3803 formulated and released, become the first domestic LED main component specification makers, showing a strong hard innovation in Guangdong.

Technical contribution of the Tang Yong team, let Guangdong LED industry value display field from general lighting to the high added, to lead the country. He said: "I can't stop, endless innovation."

Today, the air comes again. Unmanned technology has become the technology companies and car manufacturing company in an attempt to darling, the first to occupy the market at the same time, the security becomes the most difficult to overcome.

"The key technology of the third generation LED industry lies in the application of optical communication and positioning, promotion of the application will be truly safe unmanned." Tang Yong believes that if the unmanned vehicle mounted on the optical communication equipment, positioning will reach decimeter level, the driving device can be accurately positioned to absolute coordinate, safety performance is greatly improved.

Small LED behind the huge industry. Thinking after opening, Tang Yong is currently working with the agricultural enterprises to discuss cooperation, the development of ecological farming equipment LED. At the same time, and actively serve the national strategic industry, the development of optical communication equipment for high precision satellite positioning.
