Four industrial bases: Shenzhen, Xiamen, Nanchang and Dalian.
1, Shenzhen
Shenzhen has five LED (light-emitting diode) projects among them, showing that Shenzhen's semiconductor lighting industry has strong technical strength. There are 4 projects belonging to category A: Power chip industrialization key technology (Fangda Group Co., Ltd.), application research of power LED for railway traffic display (Shenzhen Haohao High-tech Development Co., Ltd.), ultra-high brightness full color LED digital tube control new technology research and development and application (Shenzhen Mingyu High-tech Co., Ltd.), LED explosion-proof lamps and military field LED lighting research and industrialization (Shenzhen Ocean King Investment Development Co., Ltd.). In addition, Shenzhen Haohao's key technology for metal-encapsulated power semiconductor solid-state lighting is listed as a Class B project.
2, Xiamen
Xiamen has been engaged in the research, development, production and application of semiconductor lighting technology and products, and has reached more than 30 companies. The scale of direct use of LED has reached several billion yuan. The main products are digital display, backlight and digital microscope illumination. , special military lighting, landscape decorative lighting, work lighting, tourist lighting, etc.
3. Nanchang (less relevant information)
4, Dalian
It is understood that Dalian "National Semiconductor Lighting Industry Base" will cover the basic materials, epitaxial wafers, chips, die cutting, grinding, packaging testing, and the upstream and downstream aspects of product application in the entire industrial chain of semiconductor lighting, forming a vertical division of labor. Horizontal integration" is the core competitiveness of the semiconductor lighting industry community. Products include high-brightness white LEDs, blue-green LEDs, etc., widely used in home lighting, automotive lighting and indicator lights. Urban lighting projects, traffic lights and large screen displays, mobile phone backlights and other application levels. Lian Luming Group and Dalian Dancai Industrial Co., Ltd. have achieved remarkable results in the fields of luminescent materials and conductive materials, etc. Hualu, Daxian and other enterprises have solid strength in the optoelectronic industry. The Dalian Municipal Government attaches great importance to this work, and has set up a photonics industrial park to undertake the task of building a national semiconductor lighting engineering industrialization base.
Secondary city
1, Hangzhou
Hangzhou is expected to take the lead in breaking through the challenges of semiconductor illuminator chips and packaging technology
The semiconductor lighting production base of the Chinese Academy of Sciences, the Hangzhou Branch of the Semiconductor Lighting Engineering Center and the Half-body Lighting Technology R&D Center of the Hangzhou Science and Technology Park of the Chinese Academy of Sciences were also established in Hangzhou. The reason why the research and development center of semiconductor lamps is placed in Hangzhou, the most important thing is to pay attention to the rapid conversion rate of Zhejiang's active market and products (smart Zhejiang people know how to promote good products).
The development of semiconductor lamps is extraordinary for maintaining Zhejiang's competitiveness in the lighting market. China occupies 60% of the world's lighting export market, while Zhejiang accounts for 60% of the country's exports.
2, Nanjing
Nanjing is one of the “joint†cities, and relevant industrial clusters are under construction, and they are striving to seize the opportunities.
It is reported that, unlike tungsten filaments for incandescent lamps, semiconductor lamps use a light-emitting chip. At present, a small number of enterprises in China are already engaged in the production of low-power light-emitting chips, mainly for screen display, such as Luopu, Handerson and other companies in Nanjing. The development of the light-emitting chip for illumination is still basically blank in China. Now, this gap is about to be filled by a Nanjing company. This company is located in Nanjing High-tech Zone, Ao Lei Optoelectronics Co., Ltd., which was founded by 7 doctors who returned to the United States, with a total investment of about 100 million yuan. It focuses on high-power (1 watt or more, equivalent to more than 15 watts of incandescent lamps). Technology is at the leading level in China. At present, the company's production line is in the commissioning phase and is expected to be put into operation early next year. Dr. Huang Zhenchun, CEO of the company, told the reporter that after the production line is fully put into production, it will reach an annual production capacity of 250 million chips, and the estimated sales revenue is about 2 billion yuan. By then, Nanjing will become the first city in China to produce semiconductor high-power light-emitting chips.
The Municipal Science and Technology Bureau is planning to use Ao Lei Optoelectronics as the leader to build a semiconductor lighting industry cluster in Nanjing. While supporting the expansion of upstream chip companies, it will extend downstream industries such as automobile lights, lighting lights, landscape lights, and mobile phone backlights. Traffic lights, screen displays, etc. At present, Nanjing has gathered nearly 10 related companies. The relevant departments of the city are also preparing a catalogue of investment attraction assets in this regard.
Other cities and businesses
1. Chongqing
Most of the semiconductor lighting enterprises in Chongqing are private enterprises, with a serious shortage of funds, small production scale, slow development, and lack of leading enterprises. In 2003, the annual output value of the industry enterprises in the city was only about 50 million yuan; Chongqing has a certain foundation in the research and development of LED materials and chips, and also has certain characteristics in application, directly and indirectly engaged in the production, sales and construction of LED products. There are more than 20 related companies and more than 10 types of products. It is planned to train one or two leading enterprises with core competitiveness in the field of LED special lighting after two to three years, and create a group of related enterprises to form a leading enterprise. The core enterprise group; the establishment of a series of brand-name products in the field of LED special lighting such as vehicle lamps, traffic signals and signage devices, landscape lighting, etc., initially established the western LED industry base mainly based on application technology development and product manufacturing. ( Recently, 15 semiconductor lighting related research institutes, colleges and universities and production enterprises in Chongqing signed an agreement and voluntarily formed a major industrialization alliance. Li Jian, executive deputy head of the National Semiconductor Lighting Engineering Coordination Leading Group, represented the relevant state departments. He attended the inaugural meeting of the industry alliance and placed high hopes on the development of Chongqing's semiconductor lighting industry.
2, Gansu
The light-emitting diode of the core device of semiconductor lighting equipment developed by Tianguang Semiconductor Co., Ltd. of Tianshui City, Gansu Province has emitted yellow light, and at the same time, it has developed red light and pole tube. Filled the gap in the northwest region without the optoelectronic industry.
Solid-state lighting is of great significance, but it really needs to enter the general lighting market. There must be major breakthroughs in technology and cost. It also requires a lot of investment and long-term eyesight, which is generally not borne by companies that are profit-oriented. Therefore, all countries in the world have initiated national projects to provide guidance and support.
