LED: the first industry trillion market in twenty-first Century

From just the end of the 2005 Beijing international LED exhibition we learned the following information, with LED technology continues to update and progress, LED will replace the traditional light source gained popularity in the lighting industry, which will lead to a revolution in lighting industry. This will bring great opportunities and challenges to LED manufacturing enterprises.

What is LED?

LED (light emitting diode) is a kind of light emitting device which can directly convert electric energy into visible light and radiant energy, and has the advantages of low working voltage, low power consumption, high luminous efficiency and long service life. Compared with the traditional incandescent lamp and fluorescent lamp, the utility model can save electricity by more than 90%. Data show that China's current annual electricity for lighting close to 250 billion degrees, if one of the 1 / 3 using semiconductor lighting, the annual energy saving of about 80 billion degrees, equivalent to the annual electricity consumption of the Three Gorges power station. China's 11th Five-Year plan has been building an energy-saving society on a very important position, then the future of China's demand for energy efficient products will rapidly expand.

LED advantage

Conductor light-emitting diode (LED) as the third generation semiconductor lighting source. This product has a lot of fantastic advantages: (1) high light efficiency: almost all of the spectrum concentrated in the visible light frequency, the efficiency can reach 80%-90%. The light efficiency of incandescent light efficiency is only about 10%-20%. (2) the light quality is high: because there is no ultraviolet and infrared ray in the spectrum, so there is no heat, no radiation, is a typical green lighting source. (3) low energy consumption: single power generally 0.05-1W, through the cluster can be tailored to meet different needs, little waste. As a light source, under the same brightness, the power consumption is only 1/8-10. (4) long life: luminous flux attenuation to 70% standard life is 100 thousand hours. A semiconductor light can be used under normal circumstances 50 years, even if the longevity of people, life will be used up to 2 lamps. (5) reliable and durable: no tungsten, glass and other easily damaged parts, non normal scrap rate is very small, very low maintenance costs. (6) the application of flexible: small size, can be flat packaging, easy to develop into thin and short products, made point, line, surface of various forms of specific applications. (7) safety: the working voltage is about 1.5-5v, and the operating current is between 20-70mA. (8) green environmental protection: waste can be recycled, no pollution, unlike fluorescent lamps containing mercury. (9) the response time is short: to adapt to frequent switching and high-frequency operation occasions.

Examples abroad

The U.S. Department of energy also has a similar forecast that by 2010, half of the incandescent light in the United States, if replaced by LED, will save only $35 billion. In terms of service life, LED uses a solid package, solid structure, life of up to 100 thousand hours, is a fluorescent lamp of 10 times. In terms of environmental protection, the use of LED instead of fluorescent lamps, fluorescent tubes to avoid the overflow of two mercury pollution.

Action in China

In June 17, 2003, by the Ministry of science and technology China led the establishment of a cross sectoral, cross regional, cross industry "national semiconductor lighting project coordination leading group", put forward the implementation of the general principles of semiconductor lighting project in China, was established from the leading group to coordinate the date to 2005 before the end of this period of time, for emergency start period semiconductor lighting project, and in the "fifteen" key plan emergency start semiconductor lighting industrial major key technology projects, this period should combine the development of the national long-term technology development plan and the Eleventh Five Year Plan for science and technology research, put forward the overall development strategy of Chinese semiconductor lighting industry and the implementation of the program. Starting in 2006, "the year of 11th Five-Year", the state will promote the semiconductor lighting project as a major project.

Good prospects

Industry prospects LED industry's most attractive prospects may not be currently seen applications. At present, it is generally accepted that photoelectron technology is the most advanced technology in the twenty-first Century. If the representative of the leading industry in twenty-first Century, ranking, the first is the optoelectronics industry, the second is the information and communication industry, the third is the health and welfare industry.

The scientific community predicts that by 2005, optoelectronics industry output will reach the level of electronic industry output value; by 2010, the optoelectronic information technology as the leading information industry will form a $5 trillion industry scale; from 2010 to 2015, the photoelectron industry may replace the traditional electronic industry, in twenty-first Century to become the largest industry, and has become an important symbol to measure a the development of the national economy and the comprehensive national strength.

LED battle stock pool first echelon

At present, the Ministry of science and technology has approved Shanghai, Dalian, Nanchang, Xiamen and Shenzhen as an industrial base. The corresponding A shares of listed companies have a base in Nanchang 600363 LIAN photoelectric (line stock has nearly doubled), Xiamen base 600203ST Furi (short term limit for two consecutive days), and the largest amount of domestic investment in Dalian base 000055 A large.

A large LED which has the domestic largest amount of investment in Dalian base of the most concern, the stock was in March during the 04 years of Shanghai semiconductor forum created 4 consecutive daily limit, the stock of short-term trading closed 200 million single, double and a number of records.

The company's semiconductor lighting industry has completed the construction of the two phase and began to put into operation, the product performance indicators are stable than the original level, ranking the leading domestic level. High power and high brightness semiconductor chip as the key technology of semiconductor lighting, is listed as the "fifteen" National Science and technology program "semiconductor lighting industrial technology development" major projects. The company successfully developed
