Nanchang, a city located in the central part of China, is known for its vibrant nightlife, especially along the Lijiang River. Every night, the city lights up with an impressive LED light show that stretches over 8 kilometers. This dazzling display involves nearly 300 high-rise buildings and attracts thousands of visitors. The radiant lighting not only highlights Nanchang's unique charm but also holds a special place in the Guinness World Records as the largest building complex to participate in a fixed sound and light show.
What many people may not realize is that almost one-third of the LED lights used in this spectacular show are manufactured in Nanchang itself. As international manufacturers gradually withdraw and coastal LED companies seek to relocate, Nanchang has seized the opportunity by leveraging its advanced silicon substrate LED technology. This move has helped the city transition from a technical hub to a major industrial center.
The colorful lights not only illuminate the nights of Nanchang’s residents but also symbolize the city’s breakthrough in the LED industry. With a strong foundation in semiconductor lighting, Nanchang has developed a complete LED industry chain, supported by skilled professionals and research teams. However, despite the industry's growth, many companies still struggle with inefficiency, lack of core patents, and intense competition in the low-end market.
In January 2016, a major breakthrough occurred when the "High-efficiency GaN-based Blue Light-Emitting Diode on Silicon Substrate" project won the first prize of the national technology invention award. This achievement marked the third global blue LED technology route and broke the monopoly of Japanese and American companies. It opened the door for Nanchang to access the global billion-dollar LED market.
Since then, the Chinese LED industry has had a true "Chinese core," and the global semiconductor lighting landscape has been reshaped. Today, Nanchang is home to more than 30 LED companies, contributing significantly to the city's economy. In 2016 alone, these companies generated over 6.5 billion yuan in main business income, forming a cluster centered around the Nanchang High-tech Zone and the Economic Development Zone.
The city's LED industry has evolved into a comprehensive layout, with different areas focusing on various stages of the supply chain. From silicon substrates and epitaxy to chip packaging and application products, Nanchang has established itself as a key player in the domestic semiconductor lighting industry.
With the rise of silicon-based LED technology, Nanchang has become a hotspot for both domestic and international enterprises. Companies such as Ou Feiguang, China Energy Saving Lighting, and others have set up operations in the city, further strengthening the local LED industry chain. The development of the "Nanchang Optical Valley" has led to an "One Valley and Multiple Parks" industrial layout, including LED Industrial Park, Intelligent Mobile Terminal Industrial Park, and more.
Nanchang is also focusing on high-end product development, with companies like Jingneng Optoelectronics developing LED lighting solutions for automotive, mobile, and outdoor applications. The performance of silicon substrate LEDs has made them popular in the global market, with many products using this technology.
To support the industry's growth, Nanchang has implemented policies to attract investment, talent, and innovation. Through strategic partnerships and global recruitment, the city aims to build a world-class LED industry cluster. By 2020, Nanchang expects to see several large enterprises with significant revenue, further solidifying its position in the global LED market.
As Nanchang continues to develop, more optoelectronic companies are joining the "Nanchang Optical Valley" express train, heading toward a bright and prosperous future.
