Next to the Lijiang River passing through the city, there will be a dazzling LED light show every night. With an area of ​​8 kilometers, nearly 300 high-rise buildings are involved, and countless people are dumped. The radiant lighting band not only explains Nanchang's unique charm, but also is the Guinness Book of the world's largest building to participate in a fixed sound and light show.

What many people don't know is that nearly one-third of the LED lights used in the light show are produced in Nanchang. In the gradual withdrawal of international manufacturers and the coastal LED (semiconductor lighting) enterprises seeking gradient transfer, Nanchang, as the capital city of the central region, is taking advantage of the advantages of silicon substrate LED technology to advance from the technical highland to the industrial plateau.

The colorful lights not only illuminate the nightlife of Nanchang people, but also illuminate the breakthrough road of Nanchang LED industry.

LED core technology "leads" the world

As a national semiconductor lighting engineering industrialization base and a national “Ten Cities and Ten Thousand” semiconductor lighting application engineering pilot city, Nanchang has accumulated a solid industrial foundation in decades, forming a relatively complete LED industry chain, with a high quality. The R&D and operation management team and a group of skilled industrial and technical workers are also the carriers of research and development and industrialization of silicon-based LED technology in Jiangxi Province.

Although the LED industry has entered a period of prosperity in Nanchang, the prosperity behind most companies is the inefficiency of most companies. Most enterprises lack core patent technology and brand, and the homogenization is serious. They struggle in the low-end lighting market by spelling price, scaling, and investment.

"Whether it is international or domestic market, the semiconductor lighting industry has always shown a low-end market bloody hurricane, a large number of enterprises are unsustainable, and even bankruptcy; high-end market is controlled by a few large manufacturers, more than 90% of the products rely on imports The situation." Wang Min, CEO of Jingneng Optoelectronics (Jiangxi) Co., Ltd. said.

But all this was broken in January 2016. On January 8, 2016, the “High-efficiency GaN-based Blue Light-Emitting Diode on Silicon Substrate” project jointly completed by Nanchang University, Jingneng Optoelectronics (Jiangxi) Co., Ltd. and China Energy-saving Crystal and Lighting Co., Ltd. won the only 2015 The first prize of the national technology invention became the third blue LED technology route in the world.

After completely breaking the Japanese company's monopoly sapphire substrate and the US company's monopoly of silicon carbide substrate semiconductor lighting technology, and eliminating the patent mines carefully buried by the international LED giant over the past decade, Nanchang also has opened the global billion-dollar market. The "golden key".

Since then, China's LED industry has a pure "Chinese core." The global semiconductor lighting industry has also been redefined since then.

Crystal energy photoelectric production workshop

More than 30 LED lighting companies in the city

After experiencing the “fission” expansion from scratch and weakening, the Nanchang LED industry chain has become more and more perfect.

Since September 2014, the first LED packaging enterprise in Nanchang has been put into production, and the communication equipment manufacturing industry led by Oufeiguang, Xingfei Technology, Lianchuang Electronics, Zhengxing Optoelectronics, etc.; with Jingneng Optoelectronics, Crystal and Lighting, and Chuang Optoelectronics and other leading LED industry; the electronic components manufacturing industry led by Lingguang Technology, Yiyuan Digital, Guangsheng Electronics, etc. have settled in Nanchang.

Nowadays, enterprises all over the LED substrate, LED epitaxy, LED chip, LED package and LED application industry have made Nanchang have a pivotal position in the domestic semiconductor lighting industry.

According to the data, in 2016, more than 30 semiconductor lighting companies in Nanchang achieved a main business income of 6.5 billion yuan, initially forming a cluster center with Nanchang High-tech Zone and Nanchang Economic Development Zone, and expanded in Qingshan Lake District, Jinxian County and Nanchang County. The regional layout of the district.

Among them, the high-tech zone focuses on the development of key core technologies such as silicon substrate LED chips and MOCVD equipment, and at the same time supporting the development of production equipment, raw materials, brackets, optical components and other middle and downstream products; key areas for the development of MO sources such as MO sources in the Economic Development Zone Materials; Qingshan Lake District, Jinxian County focus on the development of device packaging, application products, to create a device packaging base and application product production base.

The LED industry has formed an industrial layout of “One Valley and Multiple Parks”

With the breakthrough of silicon substrate LED technology, Nanchang LED industry began to know and understand more and more people. More and more people in the industry are beginning to get used to calling silicon-based LED lamps "Nanchang bulbs" - the brand effect of silicon-based LEDs is slowly forming.

For more upstream and downstream enterprises, Nanchang has become a "hot soil" for the LED industry, and the LED industry chain has taken shape.

On the high ground of silicon substrate LED technology, a number of well-known enterprises at home and abroad such as Ou Feiguang, aerospace communication Haipai mobile phone, China Energy Saving Lighting, Yiyi Technology, Meifasi and Xincheng Microelectronics have been gathered. Nanchang silicon substrate LED industry chain is becoming longer and stronger, and forming a strong industrial cluster. Around the construction of "Nanchang Optical Valley", Nanchang LED industry is forming an industrial layout of "Yigu Duoyuan" such as LED Industrial Park, Intelligent Mobile Terminal Industrial Park, Applied Electronics Industrial Park, and Photovoltaic Industrial Park.

Improve the industrial chain and lay out high-end product development

Good thermal performance and luminous quality, the industry said that "silicon substrate LED technology is born for the high-end market of high-power lighting." Therefore, in the process of industrialization, Jingneng Optoelectronics focuses on the research and development of lighting products in the high-end fields of LED applications such as automotive lighting, mobile flash, mobile lighting, outdoor lighting, high-end indoor lighting, and special lighting.

Silicon substrate LEDs perform well in the lighting market. In the field of mobile phone flash applications, Jingneng Optoelectronics is the largest domestic manufacturer of shipments, with a growth rate of 300% last year. In the field of automotive headlamps, Jiangxi Luye Auto Lighting Co., Ltd., which uses silicon substrate LED technology, was put into production last November. The company has an annual output of 500,000 sets of LED lights and LED light source modules. ability. In the field of mobile lighting, one out of every two flashlights exported in China uses silicon substrate LED lamp technology.

Nowadays, the LED light source technology has become stronger, and the chip control technology has not fallen. The Nanchang LED industry chain is approaching in an increasingly perfect direction, which is bound to attract more related companies to enter.

Building a nest to attract phoenix, global recruitment partners

After the "silicon substrate high-efficiency gallium nitride-based blue light-emitting diode" project broke the monopoly of foreign large enterprises, foreign LED companies began to "encircle the coffers" of related enterprises. In the face of powerful international competitors, how can we quickly break the scale of the industry and create a "blood path"? "What we can do is to borrow money, borrow wisdom, and borrow strength." Wang Min said.

In December last year, Jinshajiang Venture Capital, Hongcheng Capital, Wenxin Investment and other institutions invested in LED downstream application enterprises, "Bao Tuan" formed the Nanchang Optical Valley Group. Subsequently, Jingneng Optoelectronics established a technology platform, a capital platform, an industrial park platform and a flexible manufacturing platform under the Nanchang Optical Valley Group. As a result, it will launch a LED business partner program for the global market, attracting project companies and talent elites from all over the world. , build a high-end LED industry cluster in Nanchang, and help build the "Nanchang Optical Valley."

Provide technical support for funds, provide flexible manufacturing production line incubation projects with technology, and provide standard workshops for projects with “stay in the bag”... At present, there are more than 20 middle and lower-end LED companies in the forefront of the global market. And the supporting manufacturers intend to settle in Nanchang, and the "Partnership" with Nanchang LED enterprises.

Policy-driven, promoting the construction of "Nanchang Optical Valley"

After the silicon substrate LED project achieved technological breakthrough and won the “golden key” of the world's third semiconductor lighting industry, the province formulated and issued the “Implementation Plan for Building Nanchang Optical Valley and Building Jiangxi LED Industry Base”. Jiangxi Zhizhao cultivated the semiconductor lighting industry into a new growth pole of the province's industrial economy during the “13th Five-Year Plan” period, which enabled the province's LED industry to achieve a revenue of 100 billion yuan in its main business in 2020, including the main business income of silicon substrate LED. Up to 50 billion yuan.

Similarly, in order to support the development of the optoelectronic industry, Nanchang City provides policy support from land, capital, talent, employment, investment and financing, entrepreneurial innovation, mergers and acquisitions, scientific and technological achievements, government procurement, and construction of industrial public service platforms. Strive to reach 5 enterprises with a main business income exceeding 10 billion yuan and 1 enterprise with over 30 billion yuan in 2020; 10 LED giants leading in various market segments will be formed, and the total revenue of the main business will exceed 10 billion yuan. .

In Nanchang, more and more optoelectronic enterprises have taken the “Nanchang Optics Valley” express train to the bright future.
