Developing solid state lighting to conserve power resources

The newspaper published notice since July 29th, "I offer a strategy for the construction of a conservation oriented society" essay activities since, can receive hundreds of articles every day, from all over the country contribute more letters as a snowflake fly to ask the telephone also continuously on matters. Some of them and the editorial department to explore their ideas and ideas, and some invited reporters to interview the local advanced practices and experience. This vividly shows that the implementation of Scientific Outlook on Development, building a conservation oriented society, both the CPC Central Committee and the State Council made a major strategic decision, but also the common aspiration of the masses and hot topics. The newspaper from today "special provision" I offer a strategy for the construction of a conservation oriented society "essay selected" column, countermeasures and suggestions have been published all readers for the construction of economical society, and the Chen Lianghui 14 Chinese Academy of Engineering jointly provide the "development of solid-state lighting saving power resource" as the opening article at the same time, welcome readers to actively contribute.

Energy saving and new energy development are equally important, while saving more economic and environmental protection should be put in the first place. In the power saving, lighting energy saving effect is particularly significant. Semiconductor light-emitting diode (LED) and organic light emitting diode (OLED) as the representative of solid-state lighting technology, by improving the efficiency of electro-optical conversion to reduce costs, will become the most effective way of general lighting energy saving.

In the world, since the last century, the world is still the main energy of fossil fuels. If there is no surprising new mineral deposits, at the current pace of development, the global fossil fuel will be rapidly depleted, and its mining and use of the process needs to pay a huge environmental costs.

Solution to the energy shortage in the first is the development of new green energy, such as solar energy, nuclear energy, wind and water etc.. After the completion of the three phase project of the Three Gorges hydropower station, the total installed capacity reached to 18 million 200 thousand kilowatts, with an average annual generating capacity of 84 billion 680 million degrees, and the performance was very impressive. As authoritative figures say: Three Gorges power generation can illuminate half of china. In view of the rapid development of China's economic construction and the continuous improvement of people's living standards, even if the full completion of the Three Gorges project power supply, China's energy gap and the potential for effective use is still great.

In the use of power structure in the world in the developed countries of the United States, Japan and Europe and other lighting electricity accounted for about 20% of total electricity consumption. China Green Lighting Project Promotion Office of the special survey shows that the proportion of China's lighting electricity in the whole electricity is about 12%. 2003 National generating capacity of 19107 degrees, compared with an increase of 15.52% in 2002. Temporarily according to the growth rate of electricity consumption growth rate of less than 5% of the conservative calculation, by 2010, China's power generation is expected to reach GDP billion, lighting power consumption is estimated to be more than 300 billion degrees above 27000. If the lighting to save electricity by a percentage point, you can save 2 billion degrees to 3 billion degrees; if the lighting electricity savings of 1/3, you can save electricity by 100 billion degrees. Visible, the lighting as the most effective energy-saving environmental protection engineering and energy saving means, not the slightest.

Solid-state lighting refers to the use of solid-state light emitting device as a light source lighting technology, mainly comprises a light emitting diode semiconductor lighting (LED) and organic light emitting diode (OLED). LED lamp as a light source, has the following advantages: high photoelectric conversion efficiency, low power, long service life, can be selectively emit monochromatic light, can efficiently emit white light, so it can greatly save energy. LED lamp current efficiency has been more than incandescent lamp, fluorescent lamp is not yet, but in 10 years, the electro-optical conversion efficiency and service life will be fluorescent lamp of 1.5 times and 10 times. Under the above background, we put forward the idea and suggestion for the development of China's solid state lighting:

On solid-state lighting overall development strategy, suggestions will be included in the national science and technology development of solid-state lighting in the long-term planning of major projects and "11th Five-Year" plan, strengthen the research and production of solid-state lighting.

In 2006 to 2020 15 years, the need to invest 5 billion to 10 billion yuan, for the development of solid-state lighting technology with independent intellectual property rights, the semiconductor LED lamp reached 150 - 200 lm/W, 15 yuan /klm level; the establishment of solid-state lighting industry, which entered the general lighting market, and share 30% - 50% of the market share, and promote green lighting; to achieve the above 30% years of lighting energy-saving lighting, saving 100 billion degrees, equivalent to build a Three Gorges power engineering. To this end, should be organized by the government, the focus of leadership, timely guide enterprises to intervene, and the development of stage goals, phased implementation.

On 11th Five-Year during the solid-state lighting stage goal: "one center, two chain, to achieve technological breakthroughs, and with the popularity of popular green lighting, the formation of China solid state lighting solid technical foundation and a sunrise industry.

"A research center of National Engineering Research Center of solid state lighting-

With new mechanism focus on the national research institutes, universities and industry elite talent, the state investment of industrial sector and the financial sector investment, the formation of achievement sharing mechanism, as well as international standards and a world-class development of solid-state lighting research, and the transformation platform.

"Two chain" is a solid state lighting technology research: namely in solid state lighting engineering research center as the backbone and the staff, the national development and research work organized in the national support and leadership, strengthen international cooperation, strengthen the digestion and absorption of imported technology, in order to achieve the innovation based on the
