Not long ago, the news that all 45000 street lights in Yinchuan City, the largest energy-saving renovation project for urban road lighting in China, have been replaced with LED lamps, has attracted the attention of many people in Nanchang. Why do people in Nanchang care about the changes in street lights when the two places are thousands of kilometers apart?

Originally, these street lights were all high-power LED street lights independently developed by Nanchang's local LED enterprise, Zhonghuaneng Latticelight Lighting, as well as new EMC (Contract Energy Management) mode and smart lighting technology, which are typical of Nanchang manufacturing and Nanchang technology. They have continuously won EMC projects in multiple cities both inside and outside the province, becoming a leader in the national lighting energy-saving renovation industry.

Dr. Wang Min, Chairman of the Jiangxi LED Alliance, said, "We have taken silicon substrate LED technology as the core, connected the entire industry chain, and driven the total sales of industrial clusters nationwide to exceed 25 billion yuan, maintaining an annual growth rate of over 20% and forming a certain industry thickness."

The thickness determines the span. The pursuit of industrial thickness for silicon substrate LED has never stopped, and it has always accumulated the power to support the global reputation of Nanchang's LED industry.

Thickness lies in deep cultivation of high-end products - champions emerge one after another

This is an ordinary flashlight, but as soon as it shines, you will find that its light spot is uniform, the beam is concentrated, and there is no traditional product's light and dark halo. This flashlight uses a silicon substrate LED chip.

Due to its unique advantage of high-power directional light, when silicon based LED chips entered the field of mobile phone flash, they immediately became a dazzling star, and domestic and other top brand mobile phone manufacturers rushed to extend an olive branch. Now, on average, 10 million new smartphones are added nationwide every month, using the LED phone flash of Crystal Energy Optoelectronics, ranking among the top in terms of scale in China. Dr. Wang Min, the CEO of LatticePower, said, "In the LED industry, only by achieving the strongest segmentation of the market can enterprises have hope. LatticePower aims to enter the most high-end international market."

To this end, LED supported by silicon substrate continues to make breakthroughs in the field of subdivision. In the off grid lighting market, it has dominated the domestic high-end high-power flashlights, headlights, mining lamps and other fields, and its shipment volume has remained at the forefront for four consecutive years. In the automotive lighting market, it has become a domestically produced light source entering the front mounted headlight market and dominates the domestic shipment volume in the rear mounted market. In the UV market, it is widely used in industrial curing, nail art, photocatalysts, and other fields, and its domestic shipment volume remains at the forefront. In the aviation industry with the highest technical requirements, it is also beginning to emerge.

The emergence of leading sub markets has gradually built a champion matrix for the LED industry in Nanchang, providing a strong engine for the entire industry to move from low-end competition to high-end intelligent manufacturing. At present, the global LED market has a scale of nearly trillions of yuan, and the high-end market with advantages in silicon substrate LED technology also has a vast space of over 200 billion yuan. This has created the possibility for Nanchang to further cultivate more segmented market champion enterprises.

Thickness lies in accelerating fission - "partners" working together for mutual benefit

High brightness, low power consumption, long lifespan, and cool appearance. Nowadays, LED headlights with these characteristics have become an important reference for consumers when choosing cars. It is predicted that the domestic LED car light market will exceed 46 billion yuan in 2021. However, this market has always been monopolized by a few foreign companies due to high technological and capital barriers. But recently, a company that has only been in operation for over two years - Green Field Automotive Lighting - has begun to show its edge in this field and quickly entered the supply chain of several well-known OEMs.

What does Green Field rely on to dare to compete in a top tier arena and master like LED headlights?

On December 2, 2016, Nanchang Optics Valley Group, Nanchang Municipal Government, CSA (National Semiconductor Lighting Engineering Research and Development and Industry Alliance) and other industry associations officially released the Global LED Business Partner Plan, jointly accelerating the transformation of technological advantages in the silicon substrate LED industry into market advantages.

Everyone picked up firewood and the flames were high. At present, the global LED business partnership plan has gathered more than 10 related enterprises, becoming the backbone force for expanding the industrial thickness of silicon substrate LEDs. With the industry as the link, a number of major LED industry projects have been launched in Nanchang City. Newly introduced projects such as Qianzhao Optoelectronics, Zhaochi Group, and Rainbow Group are currently under construction, and are expected to add an output value of 20 billion yuan after reaching production.

"Although silicon-based LED has formed a certain industrial scale, there is still a certain gap in strength and supporting facilities compared to other technological routes. In the future, only by leveraging technology, capital, market and other links to jointly cultivate the industrial soil can a true competitive advantage be formed." Wang Minbo said.

Thickness lies in continuous innovation - "Made in Nanchang" accumulates and develops slowly

A light pole covered in treasures. At the top of the pole are environmental monitoring devices and 4G communication base stations, slightly below are WIFI antennas and intelligent security cameras, further down are smart media displays and call locators, and at the bottom is an electric vehicle charging station. This is no longer just an electric light pole, it's simply an information technology equipment integration system armed to the teeth.

At Aixihu North Road in Nanchang High tech Zone, the reporter found such a light pole. Industry experts told reporters that with the new requirements of 5G construction for base station density and the continuous popularization of Internet of Things applications, LED street lights have inherent information advantages. Once connected to 5G through ubiquitous carriers such as light poles, interconnected with the Internet of Things, and combined with future applications such as smart transportation, autonomous driving, and intelligent mobile internet, it will open up an unlimited market.

Seize the future and seize opportunities. At present, due to Nanchang's long-term accumulation in LED substrate technology, not only is it facing a blue ocean in the field of smart lighting based on smart light poles, but it has also found a stage for silicon substrate technology to showcase its strength in cutting-edge fields such as Micro LED displays and gallium nitride (GaN) based power devices, which have great prospects.

It can be said that the silicon substrate LED technology, which once won the first prize of the National Technology Invention Award, has not only contributed to technological innovation but also thrived in it. Nowadays, as a leading enterprise in silicon substrate LED technology, LatticePower and the entire silicon substrate LED "army" still regard technological innovation as the key to cultivating industrial soil and enhancing future competitiveness. In recent years, the yellow green light chips developed by the National Silicon based LED Engineering Research Center of Nanchang University have achieved international leadership; LatticePower has made technological breakthroughs in CSP (chip level packaging) for the future, achieving large-scale production and entering the supply chain of internationally renowned enterprises; The flat lens technology developed by Zhonghuaneng Crystal and Lighting effectively solves the problem of sulfur deposition in street lamps

The continuous emergence of a large number of innovative achievements will significantly elevate the position of "Made in Nanchang" in the global LED value chain.

Journalist's note:

Silicon substrate LED technology has been going through 15 years of hard work, but with steady steps and full confidence. Nowadays, with the wholehearted support of provinces and cities and the unremitting efforts of the industry, the silicon substrate LED industry has formed a full industry chain in Nanchang, and has accumulated certain thickness in the industry through deep cultivation of high-end, accelerated fission, and continuous innovation. However, there is still a certain distance between this thickness and the goal of supporting Nanchang to build a globally influential LED industry cluster.

In the rapidly changing LED industry, facing the intense competition in the industry, if enterprises do not advance, they will retreat, and if they progress slowly, they will also retreat. Therefore, in order to accelerate the development of silicon based LED, a core technology born on red soil, and transform Jiangxi, especially Nanchang's 15 year commitment to this technology into a powerful engine driving high-quality leapfrog development in the province, it is necessary for the government, investment institutions, banks, and enterprises to further strengthen their confidence, gather consensus, increase investment, continuously maintain and expand their existing technological advantages, and continuously enter more cutting-edge technology fields and markets, And promote the implementation of the global LED business partnership plan through "technology+capital", truly making Jiangxi's treasure shine brightly.
