Visit: LED products have been favored by the public yesterday, in the Hongcheng big market lighting wholesale market, the reporter saw that the people who buy lamps are endless. The owner of a lighting store in the market told the reporter: "None of the people will choose incandescent lamps now. The original LED lights are expensive. You can't afford them. Now they are cheaper. More and more people are buying. The reason is the quality of LED lights. Ok, on the other hand, the reason is that the price is cheap."
It is understood that in 2009 the country issued the "LED energy-saving industry development advice", in 2011 released the elimination of incandescent lamp roadmap, which greatly promoted the development of LED energy-saving lamp market, and with the continuous development of LED energy-saving products, LED The cost of the lamp is gradually reduced.
The reporter learned that LED products not only enjoy the favor of the public, but also play an irreplaceable role in urban development. In the implementation of the “Ten Cities and Ten Thousand Miles†project in Nanchang, the street lamp management department actively adopted energy-saving measures, and all the landscape lights used LED energy-saving lamps. In addition, in the lighting project on both sides of the Lancang River, the LED energy-saving lamps are basically used.
Status: Nanchang LED industry is flourishing <br> <br> It is understood, Nanchang is the earliest engaged in the development and production of LED area, has laid a solid foundation for the development of Nanchang LED industry cluster, and years ago in LED upstream, midstream, The downstream industry has achieved large-scale production.
Yesterday, the reporter learned from the Nanchang Science and Technology Bureau that after nearly 30 years of development, Nanchang has more than 20 LED companies, and relying on leading enterprises such as Lianchuang Optoelectronics, Jingneng Optoelectronics and Xinlei Optoelectronics, it has also spawned nearly 100 The supporting enterprise has initially formed a relatively complete industrial chain such as LED substrate production, epitaxial wafer, chip manufacturing, and chip packaging application products.
It is understood that Jingneng Optoelectronics Co., Ltd. located in the high-tech zone of Nanchang City has broken through the key technologies, successfully applied the silicon substrate LED chip to lighting, and created a silicon substrate LED industrial chain with 10 units.
Advantage: "silicon substrate LED technology" <br> <br> Nanchang advantage of the world's leading LED industry embodied in the upstream substrate and the epitaxial wafer production process. Relying on the “silicon substrate blue LED technology†developed by Professor Jiang Fengyi from Nanchang University, the monopoly of upstream and core technologies in Japan and the United States has been broken, forming a three-pronged situation of three international LED upstream substrate technologies: sapphire, silicon carbide and silicon. Nanchang Jingneng Optoelectronics Co., Ltd. has obtained more than 200 patents worldwide based on this technology. This not only has a very important significance for China to occupy a favorable position in the international LED industry, but also provides a key innate advantage for the development of the LED industry in Nanchang. In addition, Nanchang is in the forefront of the country in the research of power high-brightness LED chip manufacturing, high-power white LED device packaging and semiconductor lighting source system integration technology.
In addition, the reporter also learned that the MOCVD equipment developed by Nanchang University has been successfully developed. This equipment can be used not only for the production of LED epitaxial wafers of traditional substrates such as sapphire, but also for the production of LED epitaxial wafers on silicon substrates. The cost performance is better than that of similar foreign products. At present, small-scale production development is underway. In recent years, the industrialization of LED core equipment and technology with complete intellectual property rights in China will be realized.
Prospects: Nanchang number of policies to support the LED industry <br> <br> Yesterday, reporter learned that, in order to support the development of LED industry, Nanchang last year introduced the "number of policy measures to support Nanchang LED industry" from Nanchang All aspects of funds, taxes, talents, market development, and industrial development support services are supported. The goal is to focus on the LED industry cluster in Nanchang, and to promote the coverage of surrounding provinces to create LED R&D, design, production and sales center. At that time, Nanchang is expected to become a “LED City†and establish LED products through cooperation with international companies. One of the export bases. Rapidly expand the Nanchang LED industry, and strive to achieve an output value of over 15 billion yuan by 2015 and an output value of over 50 billion yuan by 2020. 
It is reported that Nanchang has always been one of China's semiconductor lighting engineering industrial bases. Many years ago, it has formed large-scale production in the fields of upstream epitaxial chips, midstream packaging, and downstream application output. In recent years, with the development of the LED industry, Nanchang has become one of the seven bases of China's LED industry. Nanchang's core technology "silicon substrate blue LED technology" is in the world's leading position.
