Saving energy and developing new energy have become the basic choices for energy development in the world in the 21st century. China is a major country in the production, consumption and export of lighting products in the world. Lighting power accounts for 12% of the country's total power generation and is growing at a rate of 5% per year. Lighting power saving is a breakthrough in solving the contradiction of power shortage and achieving sustainable development in China, and the most revolutionary technological breakthrough in energy saving in the field of lighting is semiconductor (ie LED) lighting.
First, LED lighting is triggering a revolution in electric light source products.
In 1879, the American inventor Edison successfully developed the first practical incandescent lamp. The human society bid farewell to the era of electric light illumination, which marked a great progress in human civilization. In the development process of the electric light source lighting industry for more than 100 years, three generations of electric light source products such as incandescent lamps, tungsten lamps and fluorescent lamps have been successively brilliant. So what is the new light source for lighting in the 21st century? The scientific and technological community generally believes that it is a semiconductor light-emitting diode (English name LightEmittingDiode, abbreviated "LED", the same below), that is, the fourth generation of electric light source products.
As a new type of high-efficiency solid-state light source, LED lighting is based on semiconductor chips, using electrons to emit light, directly converting electrical energy into light energy, rather than the "old face" of filaments and bulbs. The so-called high-power LED refers to an LED that operates at a current of 350 mA, a voltage average of about 3.4 V, and a power of more than 1 W. From the perspective of the industrial chain, the LED lighting industry is divided into upstream, midstream and downstream. Among them, the manufacture of LED substrate materials, epitaxial wafers, chips, etc. is an upstream industry, and the packaging of LEDs is a midstream industry, and the manufacture of lamps based on LED light sources is a downstream industry. Obviously, the upstream industry is a technology-intensive industry, and the investment quota and process control technology are difficult; the downstream is a labor-intensive industry, and the industry entry threshold is low; the mid-stream industry is between the two.
As a light source, the advantages of high-power LED are reflected in three aspects: energy saving, long life and green environmental protection. LED does not rely on filament heating to obtain a light source, and the energy conversion efficiency is high. In theory, only 10% of the energy consumption of the incandescent lamp, 50% of the energy consumption of the fluorescent lamp, and the service life is 100 times that of the conventional bulb. The life of ordinary energy-saving lamps is more than 5,000 hours, which is five times that of incandescent lamps, while the life of high-power LED lamps is more than 50,000 hours. There is almost no maintenance cost (see Table 1 for details). According to statistics, in 2008, China's electricity consumption reached 3.43 trillion kWh, of which lighting accounted for 12%. If the luminous efficiency of LED continues to increase at the current speed and its application level accounts for 30% of the lighting market, by 2020, China can save more than 200 billion kilowatt-hours per year, and convert it by 0.8 yuan per kilowatt hour, saving 160 billion yuan. According to the current power and energy structure, it is equivalent to reducing 199.4 million tons of carbon dioxide. Unlike traditional energy-saving lamps, LED lighting uses a cold light source, no need to inflate, no glass casing, no need to add harmful metal substances such as mercury and lead, and has good color rendering, no stroboscopic, soft light and other characteristics. Improve the myopia problem of children and adolescents, so from production to use until the end of life can be described as non-polluting throughout the process, known as "green lighting." Experts and industry insiders believe that the semiconductor lighting industry will be one of the largest and most active high-tech industries in the 21st century, and it is of great significance in terms of economic competition and national security. And predict: high-power LED lighting is triggering a revolution in electric light source products worldwide, and will become another leap in the history of human lighting.
LED lighting is in line with the direction of energy saving, environmental protection, safety and sustainable industrial development. It is the most advanced lighting technology in the world today. As a high-tech industry in the 21st century, the LED lighting industry has attracted the attention of the countries and countries in the world, especially the developed countries and governments in Europe and the United States. In recent years, GE, the United States, PHILIP, Germany's OSRAM and Japan's Nichia Chemical (known as the "four leading enterprises in the field of international LED lighting") and other internationally renowned electric light source companies have invested heavily in the development of LED lighting technology and Industrialize it. The United States, Japan, South Korea and the European Union have successively launched national LED lighting plans to seize the technical and industrial commanding heights. In June 2003, China also established the “National Semiconductor Lighting Project Coordination Leading Groupâ€. The State Council approved the Ministry of Science and Technology to organize the implementation of “National Semiconductor Lighting Project†with relevant departments. It can be firmly believed that the relevant construction plans and incentive measures launched by the Chinese government will definitely benefit the LED lighting industry and will also play a positive role in promoting the civilian use of LED lighting products.
Second, the development status of Guangdong high-power LED lighting industry
(I) Overall Situation The LED lighting industry in Guangdong Province originated in the early 1990s. After more than ten years of development, it has become the most concentrated area of ​​domestic industry and an important production base and trade center for LED in China.
