â— In today's green environmental protection, high efficiency and energy saving, LED semiconductor lighting has gradually entered people's lives as a new type of industry.
â— However, in the face of broad market development prospects, the lack of key core technologies and product promotion has become the two weaknesses of the development of LED semiconductor lighting industry.
◠The upgrading of the lighting industry and the introduction of relevant national policies have opened up the “winding†for the development of the LED semiconductor lighting industry in distress.
On August 16th, in an interview with Xinshi Optoelectronics Co., Ltd., the reporter saw a special table lamp using the company's semiconductor lighting chip. Compared with the daily incandescent lamp, the light source is composed of a light-emitting diode of small grain size. . It is worth noting that behind this table lamp based on LED semiconductor lighting technology, there is a huge industry.
In 2004, four cities in Shanghai, Dalian, Xiamen and Nanchang were set up as national semiconductor lighting industrialization bases. In 2005, Shenzhen also obtained the approval of the Ministry of Science and Technology and became the fifth LED industrialization base in China.
Today, this high-power LED lighting facility has entered the lives of Zhengzhou citizens. On April 20th, the fourth street, which is 2.1 kilometers long in Zhengzhou Economic and Technological Development Zone, began to use high-power LED new street lighting.
"This is the first high-power LED road lighting system with practical and promotional value in China." Sun Jingxi, a doctor of Henan University who brought this kind of street light to Zhengzhou, said that the LED industry has become one of the most capital-seeking areas. By 2010, there will be 1/2 of the world's tungsten bulbs and all fluorescent lamps will be replaced by "millet grains".
"millet grain", big industry
“Beautiful lighting has become a witness to the rapid development of the city.†Nowadays, the pace of urban construction is accelerating, the number of outdoor lighting is increasing day by day, and the negative problems such as energy waste and light pollution have caused the government to introduce relevant policies to regulate energy conservation. The economy, “environmental protection of the city†and “green lighting†have become the endorsements of urban construction.
As a new force of “green lightingâ€, the light source of LED semiconductor illumination is a cold light source with extremely high photoelectric conversion rate, which consumes only 1/10 of the power of ordinary incandescent lamps, but can extend the life by 100 times and has high luminous purity. The use of safety, maintenance-free, pollution-free, etc., in today's promotion of environmental protection, high efficiency and energy saving, has been vigorously promoted by countries around the world.
The LED semiconductor lighting industry has taken the lead in production abroad. In the 1990s, the LED semiconductor lighting industry "imported China". In the following 10 years, China's LED semiconductor lighting industry has grown from scratch, and the industrial chain has grown. Now it has formed a market scale of 200 billion yuan.
It is understood that the current LED industry from the perspective of the industrial chain, the upstream is the manufacture of epitaxial wafers, chips, etc., the midstream is the packaging of LEDs, and the downstream is the manufacture of semiconductor illumination sources and lamps based on LED applications. The key technology epitaxial wafers and wafers of LEDs are mainly provided by foreign manufacturers, and domestic enterprises mainly rush to eat in the middle and lower reaches of the industrial chain.
"Core technology determines the direction of the industry. We can't always follow the foreign market, let others take the nose, and we must independently develop the core technology of the industry." Sun Jinglian said.
In May 2006, Sun Jinglian founded the headquarters in the American city of Mickson, Wisconsin, focusing on the development and manufacture of compound semiconductor lighting epitaxial crystals and chips. In July of the same year, Sun Jinglian returned to China to start a business and established a semiconductor lighting industry production base in Zhengzhou.
When talking about choosing to return home to start a business, Sun Jinglian said with excitement: "The geographical advantages of the hometown logistics port and the reasonable labor cost cost have deeply touched me, and I decided to establish a semiconductor lighting industry production park in Zhengzhou."
“Zhengzhou is located in the Central Plains and has extensive traffic radiation capacity and an increasingly large consumer market. Although China's current electronic processing industry belt is mostly in the eastern coastal cities, the labor costs in the coastal areas are relatively high, and the product cost is relatively high. Not conducive to business competition." Sun Jinglian said.
“Today, many large-scale technology and electronics companies have established talent reserve bases in developed cities in China. Therefore, we have chosen to establish a second subsidiary in Shenzhen to reserve outstanding talents for technology research and development.†“Semiconductor lighting industry is a worldwide industry and must take the initiative. Participate in the international division of labor, take advantage of the regional advantages of different regions, fully combine advanced technology, management experience and human resources, in order to go with the giants and quickly form an internationally competitive Chinese semiconductor lighting industry." Sun Jinglian said.
