Zhengzhou LED lighting industry to upgrade

In the promotion of green environmental protection, high efficiency and energy saving today, LED semiconductor lighting as a new industry gradually into people's lives. However, in the face of the broad market prospects, the lack of key technologies and products to promote the use of LED semiconductor lighting industry has become the two biggest weakness. The lighting industry upgrading, the introduction of relevant national policies, the opening of the ride for the development of LED semiconductor lighting industry in the plight of the". In August 16th, the reporter in the new vision photoelectric Limited company interview, the company saw a special chip of semiconductor lighting lamp, compared with incandescent lamps daily, the light source is composed of light emitting diode 1 small grain size. It is noteworthy that this is based on LED semiconductor lighting technology behind the desk lamp, containing a huge industry.

2004, Shanghai, Dalian, Xiamen, Nanchang, 4 cities were set up as the national semiconductor lighting industrial base, in 2005, Shenzhen has also been approved by the Ministry of science and technology, becoming the country's fifth LED industrial base.

Today, this high-power LED lighting has entered the lives of the people of Zhengzhou. April 20th, in the Zhengzhou economic and Technological Development Zone, 2.1 km total length of fourth km, the use of high-power LED new street lighting.

"This is the first high power LED road lighting system with practical and promotion value. "Take this street to Zhengzhou Yu Ji America Dr. Sun Jingxi said, LED industry has become one of the most popular areas of capital chasing, is expected to 2010, the world will have 1/2 tungsten lamp and all fluorescent lamps will be replaced by" rice ".

Small grain, big industry

"Brilliant lighting has become the rapid development of the city, the city is now a witness" to accelerate the pace of construction, the number of outdoor lighting problems attendant grow with each passing day, energy waste, light pollution, making the government have to introduce relevant policies to regulate, promote energy conservation, environmental protection and economic construction of the city "," green lighting "has become the city construction endorsement.

As a new force of green lighting, LED light source of semiconductor lighting is a cold light source photoelectric conversion rate is high, the power consumption of only ordinary incandescent 1/10, and life can be prolonged by 100 times, has the advantages of light high purity, safe use, free maintenance, no pollution, in promoting the green environmental protection and high efficiency energy conservation today, has been popularized all over the world.

LED semiconductor lighting industry has been put into production in foreign countries. In 1990s, LED semiconductor lighting industry "China introduction", in the subsequent 10 years, Chinese LED semiconductor lighting industry from scratch, industrial chain expansion, has formed a 200 billion yuan market scale.

It is understood that the current LED industry from the perspective of industrial chain, the upstream chip manufacturing, extended outer chip, the middle is a light emitting diode package, the downstream is manufacturing semiconductor lighting source and lamp light emitting diodes based on application. The key technology and epitaxial wafer LED is mainly provided by foreign manufacturers, domestic enterprises are mainly in the middle and lower reaches of the industrial chain snatch.

"Core technology determines the direction of the industry, we can not always follow the foreign market, so that others lead the nose, the core technology of independent research and development industry. Sun Jingxi said.

May 2006, Sun Jingxi in the United States city of Wisconsin, the headquarters of the founding of the city, mainly engaged in compound semiconductor epitaxial crystal lighting, chip development and manufacturing. In July of the same year, Sun Jingxi returned home to start a business, set up a production base of semiconductor lighting industry in Zhengzhou.

When it comes to choose home business, Sun Jingxi said excitedly: "hometown Logistics Hong Kong source advantages and reasonable value of labor cost deeply touched me, so I decided to build the production of semiconductor lighting industry park in Zhengzhou. "

Zhengzhou is located in the Central Plains, with the ability to extend the traffic radiation and increasingly large consumer market. Although most of China's electronic processing industry in the eastern coastal cities, but the higher labor costs in coastal areas, relatively high product costs, is not conducive to enterprise competition. Sun Jingxi said.

"Now, many large technology electronics companies in China's developed cities to establish talent reserve base, so we chose to build second subsidiaries in Shenzhen, reserve talents, technology research and development. "Semiconductor lighting industry is a global industry, must take the initiative to participate in the international division of labor, the use of regional advantages in different areas, technology, management experience and advanced human resources to fully combine with giant counterparts, the rapid formation of China's semiconductor lighting industry with international competitiveness. Sun Jingxi said.

Core technology

At present, LED is in the early stages of semiconductor lighting applications, is widely used in large screen display, traffic lights, mobile phone back light source, with the breakthrough and the blue and green light emitting diode was made on the third generation of semiconductor materials Gan, it will enter the normal indoor lighting, lamp, backlight, large size notebook computer backlight LCD display market.

"As a new vision photoelectric Limited company independent research and production of the formation of 'pin' one of the few companies," Zhengzhou economic and Technological Development Zone deputy director Shi Yunhui said, "most of the enterprises belong to the 'screwdriver' assembly plant. "

Lack of core technology and the promotion of the application has become the industry's two major weakness. When Yun Hui said, do not capture the commanding heights of the core technology, enterprises can only become"
