LEDs are lighting up the Chinese market

China is expected through the "led" of the new materials and new technology to save energy and create economic and strategic significance, and make it play an important role in many fields, which also means a huge market potential is formed

Night in downtown Shanghai. At present, some large cities in China need to consume a large amount of electric energy. (Zhang Ming) "LED" is "diode" (light emitting) abbreviation, its basic structure is an electroluminescent semiconductor material. Experts revealed that 12% of China's energy used in lighting. As a light source, light emitting diode at least in terms of energy saving reflects the advantages. It does not rely on the filament heating to light, energy conversion efficiency is very high, in theory, the need for electricity is only ordinary incandescent lamp 1/10, compared to fluorescent lamps, light-emitting diodes can achieve 50% of the energy saving effect. Chinese green lighting project office made a special investigation, Chinese lighting electricity annually in more than 300 billion degrees, to replace the fluorescent lamp using light-emitting diodes to replace all or part of the incandescent lamp, 1/3 lighting to save electricity, it means saving 100 billion degrees, equivalent to a total investment of more than 200 billion yuan, is under construction the world's largest power station of the Three Gorges project annual generating capacity. This rapid economic development has exceeded the speed of energy supply in China, there is no doubt of great significance, obviously help to ease the energy shortage. Similarly, the U.S. Department of energy has a similar forecast, by 2010, half of the United States if the incandescent lamp replaced by light-emitting diodes, then save only $35 billion.

In addition, the light-emitting diode using epoxy resin and other materials sealed, solid structure, the service life of up to 100 thousand hours, longer than the fluorescent lamp is more than 10 times longer than incandescent lamps. In the field of environmental protection, the use of light-emitting diodes instead of fluorescent lamps, to avoid the destruction of the fluorescent tube leakage of mercury two pollution.

At present, the daily use of mobile phone, computer, digital camera and cars, has led the figure, even some electrical switches, TV remote control on the small lights are made of this material. In addition, medical scientists have been using light-emitting diode lamp disinfection and air purification, and even to promote the growth of crops. The miner's lamp made of it has no spark, and does not cause gas explosion, which greatly improves the safety of the underground operation. The miners no longer need to work with the big and heavy power supply. Light emitting diodes are widely used in traffic lights, instruments and meters and urban landscape lighting.

In the southeast coast of China, the main economic and tourist city of Xiamen, there is a century of prosperity of the famous old commercial street, called "Zhongshan Road", known as "one of the ten famous street". But in recent years, the newly formed large shopping district robbed its scenery, and gradually lost the status of the city's commercial center. From the beginning of 2004, city managers began the transformation to save Zhongshan Road, the commercial street into a pedestrian street at the same time to strengthen their business functions, the beginning of the "night project", to "activate" a hundred years old. Now the Zhongshan Road night lights, Qi Liang, once the old street and put on the face of the young, under the change of light, yourenruzhi. The peak of the time to reach a night more than ten million people. According to local government statistics, the street retail sales per month has varying degrees of growth from 30% to 50%. And every building in the street is led lights to outline their profile, in addition to the luminous efficiency of the same condition of high power than ordinary incandescent lamp, the lamp, gas lamp is more energy-saving and longevity, LED landscape lamps can be carried out in computer program control, easy for each building is different style and sculpture pattern and adopt different lighting and color collocation. Zhongshan Road, with a light-emitting diode landscape lights out a lot of decorative effect is the ordinary neon lamp is difficult to do.

Government: start the project

Xiamen City, Zhongshan Road a department store with a light emitting diode lights outline. Zhongshan Road began the night project attracted a large number of consumers. (Li Jia) the most attractive prospects for the light-emitting diode industry may not be the current application. The international community generally views of many experts, from 2010 to 2015, the photoelectron industry may replace the traditional electronic industry, has become an important symbol of twenty-first Century the biggest industry and the measure of a country's economic development and comprehensive national strength, and the light emitting diode is the most important component of optoelectronic materials and optoelectronic industry, is the basis for the optoelectronics industry. Therefore, many countries have developed a corresponding plan.

In June 17, 2003, China "national semiconductor lighting project coordination leading group was established to determine the group from the date of establishment, the period before the end of 2005, for the project" emergency start period "to key project key technology, combined with the development of national long-term science and technology development planning and the Eleventh Five year plan for science and Technology (2006-2010), the research put forward the overall development strategy of Chinese semiconductor lighting industry and the implementation of the program. According to reports, from the beginning of this year, the next 5 years, the Chinese government will be the semiconductor lighting project as a major project to promote.

At present, China's Ministry of science and technology has approved Shanghai, Dalian, Nanchang, Xiamen and Shenzhen as an industrial base. In June last year, Shenzhen, the national guide
