Semiconductor lighting: an annual savings of Three Gorges Project

Academician Chen Lianghui Chinese Academy of engineering calculations to reporters: in 2010 China's electricity consumption will reach 2 trillion and 700 billion degrees, the lighting power consumption of more than 300 billion degrees. Because of the same brightness, semiconductor lamp power consumption is only 1 / 10 of the incandescent lamp, as long as there is 1 / 3 of the incandescent lamp replaced by semiconductor light, every year will be able to save nearly 100 billion of electricity, equivalent to a generating capacity of the Three Gorges project.

The new light source will lead to the twenty-first Century revolution lighting

The history of human lighting has gone through a long process of development. According to Chen Lianghui China Academy of engineering, human beings had long by burning wood lighting, lighting the gas began in 1772 to 1879; Edison invented the incandescent lamp, lighting the history of mankind has entered a new era. The last century at the end of 90s, with the third generation of semiconductor materials Gan breakthrough and blue, green and white light emitting diode come out, and in the birth of a new industrial revolution -- lighting revolution, its logo is a semiconductor lamp will gradually replace the incandescent lamp and fluorescent lamp. According to Li Jian, Deputy Secretary General of the State Ministry of science and technology, as a new type of efficient solid-state light source, semiconductor lighting source has a long life, energy saving, safety, environmental protection, rich colors, miniaturization and other significant advantages. Semiconductor light emitting diode as a new light source, the same brightness, the power consumption is only 1/10 of ordinary incandescent lamp, and life can be extended by up to 100 times. Semiconductor lighting technology is widely used in various fields of white general lighting, decorative lighting, automotive lighting, and other types of Transportation traffic signal display, background display, large screen, special lighting, lighting protection and tourism, light industrial products etc.. The industry generally believe that, like transistors instead of electronic tubes, semiconductor lamps to replace the traditional incandescent and fluorescent lamps is the trend. Chen Lianghui told reporters, energy saving and environmental protection will be the mainstream of the future development of the industry, the development of semiconductor lighting is not only conducive to solve the energy crisis and environmental problems, promote the traditional industry, and will greatly improve the quality of people's lives. At present, China's energy crisis is becoming increasingly serious, and semiconductor lighting can achieve the purpose of saving electricity, is expected in 2010 China's electricity consumption will reach 2 trillion and 700 billion degrees, lighting power consumption of more than 300 billion degrees. Because of the same brightness, semiconductor lamp power consumption is only 1 / 10 of the incandescent lamp, as long as there is 1 / 3 of the incandescent lamp replaced by semiconductor light, every year will be able to save nearly 100 billion of electricity, equivalent to a generating capacity of the Three Gorges project. Started the global semiconductor lighting industry battle

The United States Department of energy predicts that by 2010, the United States will have 55% of the incandescent lamp and fluorescent lamp by the semiconductor lamp replacement, save electricity up to 35 billion dollars a year, will form a large semiconductor light industry $50 billion. The face of the semiconductor market prospects and great temptation to seize the commanding heights of the emerging industries of semiconductor lighting in the world quietly started. In recent years, the United States, Japan, the European Union, South Korea, Taiwan and other countries have launched a national semiconductor lighting plan to increase research and development efforts. For example, Japan invested 5 billion yen to implement the "twenty-first Century light plan" proposed in 2006 to replace the traditional incandescent lamp with large-scale semiconductor lamp; United States Department of energy has established 13 national key laboratories, companies and universities to participate in the "national semiconductor lighting project", plans to use 10 years of time, at a cost of $500 million to develop the semiconductor lighting; the EU has commissioned 2 universities, 6 large companies, in July 2000 launched the "rainbow plan". Taiwan, China is also organizing the implementation of the relevant plans, the establishment of a production of 16 research and universities to participate in the twenty-first Century lighting source development plan". At the same time, the world's three largest lighting industry giant General Electric, PHILPS, Oswald Rahm group has launched a large-scale commercial development plan, have with the semiconductor company cooperation or mergers and acquisitions, the establishment of semiconductor lighting enterprises, and put forward in 2010, the semiconductor light emitting efficiency increases by 8 times, 100 times lower prices. China is facing great opportunities for development

In the face of growing tension in China's energy crisis, in the face of the rapid rise of major business world lighting industry transformation and emerging semiconductor lighting industry, Li Jian believes that China should seize opportunities for development in this golden commanding, China's lighting industry to reach the world advanced level as soon as possible. China is one of the world's largest producer and exporter of lighting appliances, with a huge lighting industry and lighting market. According to figures provided by the China Lighting Association, sales revenue of 44 billion 500 million yuan last year, foreign exchange earnings of $4 billion 300 million. However, the lighting industry is big but not strong, mainly to do low-end products, low profit margins, lack of international market competitiveness. It is understood that the United States now lighting 600 billion degrees per year, accounting for about 20% of the total electricity consumption. China's annual lighting power consumption is only about 200000000000 degrees, accounting for about 12% of the country's total electricity consumption.

China has a certain technical and industrial base in this field. Compared with microelectronics, the gap between semiconductor light-emitting devices in China and abroad is small. China's independent development of the first light-emitting diode, the first light-emitting diode in the world than just a few months later. Through the support of the "863" program and other scientific and technological projects, China has initially formed
