Semiconductor lighting is two or three years, the world of one of the largest lighting. If half the world's incandescent and fluorescent lights instead of the semiconductor, semiconductor light if the price can be reduced to general consumer spending levels, then the world will not save enough for the power shortage. So when the semiconductor light to enter the homes of ordinary people do?
In recent years, the world's three major light industrial giants - GE, Philips, Osram and semiconductor companies have combined to form semiconductor lighting company. Japan, the United States, South Korea, European Union also launched the national semiconductor lighting program.
Following the world trend of development of this high-tech industries, China National Semiconductor Lighting Project Coordination Leading Group has been set up in conjunction with Ministry of Information Industry, Ministry of Construction, Ministry of Education, China Light Industry Federation, the Chinese Academy of Sciences and other industries and local, started the semiconductor Lighting Project.
Semiconductor light magic
Semiconductor technology, following the Industrial Revolution led to the first - microelectronics revolution, is giving birth to a new revolution - lighting revolution. With the third generation of the emergence of GaN semiconductor materials, semiconductor technology is another positive outcome of a human sacrifice: the semiconductor light-emitting diode (LED) solid-state lighting as a new source - Semiconductor light, replace the traditional incandescent and fluorescent lamps.
National Semiconductor Lighting Project Coordination Leading Group, Li Jian cited two figures: the same brightness, the power consumption of only the incandescent lamp 1 / 10, while life expectancy is 100 times greater than incandescent lamps. "100 times is what the idea? To point 6 hours a day, a lamp can be used for 50 years, do you not take a lifetime Two Lights."
As the semiconductor lamps with energy saving, long life, maintenance-free, easy to control, and environmental protection advantages, it's widely expected that, as transistors replaced vacuum tube as the semiconductor, semiconductor light instead of traditional lights across the board. Can not solve the problem strobe lamps, semiconductor light does not exist, is truly "green light."
For the semiconductor light, the red and yellow lights are low-end products, has achieved mass production of such lamps, which cost our country the most competitive, has been used for road lighting, decoration and other special lighting. Low cost, high brightness, high power white light is the high-end products. The United States developed the latest 5-watt white light, China can produce 1.5 watt white light. But the prices are too high, is the incandescent lamp 10 times. Therefore, Japan, the United States, the European Union launched the semiconductor lighting program, the main direction is to reduce the cost. They proposed a large-scale alternative to incandescent lamps for the semiconductor schedule, roughly in 2006 and 2007.
U.S. Department of Energy plans to 2010, with 55% of the semiconductor light instead of incandescent and fluorescent lamps, annual savings of 35 billion U.S. dollars. It is estimated that seven years after the United States alone, semiconductor lighting can create a 50 billion U.S. dollars in large industry.
Base Commander semiconductor lighting the four civilian
When the Xiamen Municipal Government Deputy Secretary-General Lin Shouzhang recent high-tech from the Ministry of Science and the Division took over the leadership of the national semiconductor lighting industrial base of the sign, it means that the Xiamen and Shanghai, Nanchang, Dalian and four semiconductor lighting with a national base.
Xiamen "light Island" plan, by 2010 the industrial scale of the formation of 30 billion yuan, total investment will reach 10 billion yuan. Nanchang, Jiangxi proposed by 5-7 years of efforts, the base to reach 10 billion yuan annual output value of the economic scale. Shanghai forecast 2010 sales of 10 billion to 120 billion yuan, export 3-5 million. Shanghai will become China's LED and the photoelectron Industries Demonstration Zone, the semiconductor light industrial demonstration area of technological innovation and industrial parks. Dalian is claimed, will help run government's development model, for 2 to 3 years in the optoelectronics industry in Dalian, China and the world famous park into the optoelectronic industry base, Dalian municipal government has also set up a "photoelectric industrial park in Dalian" and the "Dalian Semiconductor lighting engineering base "leading group.
National Semiconductor Lighting Project Coordination Office of the Vice-Ren Wuling that the international advanced level, China's semiconductor lighting technology is now three to five years behind, the gap is not too much to China's existing technology base and industrial base, expected by stage The overall progress, eventually forming the core competitiveness of China's semiconductor lighting industry.
Great opportunities
"China's semiconductor lighting industry in the development of good opportunities." Jian analysis of several favorable conditions.
First, China has a huge market of lighting industry and lighting. China is now the world's largest lighting producer and second largest electrical lighting appliances exporter. In the United States was 600 billion kwh electricity for lighting, about 20% of total electricity. 5 times our population in the United States, currently only 200 billion kwh in electricity for lighting, only the United States, 1 / 3, accounting for 12% of the total electricity consumption. This means that lighting industry in China has a huge space for development. Well-off society, the masses have a new type of lighting is strong demand.
Second, our country in this field has a certain technology and industrial base. China has independently developed the first light-emitting diodes, light emitting diodes than the world's first only a few months later. Experts believe that, on the whole, our country's technology industry, the semiconductor light-emitting diode and the developed countries is only a difference of 3 years. China has initially formed from the production of epitaxial wafers, chip preparation, the device package to the integrated application of a relatively complete industrial chain. Particular package has been in the international market accounts for a sizeable share of our production, red and yellow lights in the semiconductor world's most competitive advantages lies in packaging.
Third, the semiconductor lighting industry is a plus labor-intensive and technology-intensive industries are more suitable for our conditions, the risks and difficulties are less than the microelectronics industry.
Li Jian stressed: "such a good opportunity we must seize."
Starting from the urban landscape
Li Jian also suggested that the semiconductor light should first grasp on the urban landscape lighting applications. Taking into account the cost performance, including the development of semiconductor lighting advised from the urban landscape lighting, traffic lighting, automotive lighting, special lighting, including start, especially in the urban landscape lighting, could be included in government procurement catalog, the best play semiconductor light less power consumption, long life, maintenance-free advantages. Meanwhile, pay close attention to low-cost, high-brightness, high power white light LED and system development, so that the semiconductor light early access to millions of households. The semiconductor lighting industry has not been established with international standards, to accelerate the establishment of semiconductor lighting industry standards, the formation of China's independent intellectual property rights.
