Led Industry, Major Problems Exist Five Funds Needed To Support Policy
Be considered in the next 10 years will replace incandescent
, tungsten and fluorescent "fourth-generation light source"??? LED lights much global attention, European and American countries have to include industry development strategy.
LED industry in China started late, small markets, especially in key technologies have been subject to European and American developed countries, if not accelerate the development of the Chinese market will allow the multinational corporations carve up. Some experts believe China's LED industry is in urgent need of government policy, funding and increasing support.
Power consumption of the traditional light bulb is only 1 / 10
According to Chinese Academy of Sciences description Gan Zi-Zhao, LED, also known as light-emitting diode, is the world's most advanced lighting technology. LED light bulb does not light Continuous Twisted "old faces", but on the semiconductor chip solid-state light sources for the material. It moved to the use of electronic light, converting light energy directly to electrical energy, its power consumption compared to traditional light bulbs 1 / 10, life is 100 times greater than traditional bulbs. A common energy-saving lamp life of 5,000 hours or more, is 5 times incandescent, high-quality energy-saving lamps use a year or so to recover the cost, but high-power LED light source life of up to 50,000 hours or more, almost no maintenance costs, one-time investment return bigger and more significant.
At present, lighting consumes about 20% of the power consumption, extremely scarce in the current energy situation and reduce the lighting power is an important way to save energy. According to research estimates, by 2010, if our existing 1 / 3 of lighting using LED lights, can be saving 150 000 000 000 degrees, according to 0.8 yuan per kilowatt basis, can save 120 billion yuan. In accordance with the existing energy structure estimates electricity, equivalent to emissions from 25 to 43.2 million tons of carbon dioxide, sulfur dioxide emissions to reduce 1.35 million tons.
In addition, most common shape of energy-saving lamps is very limited room for improvement, and many energy-saving lamps contain mercury and other harmful to the environment, the lamp end of life, such as being thrown away after, but not prone to energy saving and environment protection. The LED lighting is cold light source, no inflation, no glass shell, do not add mercury, from production to use the process to scrap the entire process completely avoid mercury contamination. Also, because solar thermal conversion efficiency, small heat, LED lighting can also be effective in preventing thermal pollution caused by prolonged illumination. When used in facade lighting, because LED lights are installed Office of the glass curtain wall in the floor to the glass curtain wall on the external exposure, so the tenants will not produce light pollution. In addition, LED lighting also has good color, no flash, soft light and other features, known as the "green light."
In recent years, the semiconductor light emitting material with the deepening, LED manufacturing new technology, new materials development and application of ultra-high brightness LED colors made a breakthrough. LED lighting for its high luminous efficiency, less power consumption, long life, safety reliability, environmental health and other advantages by the industry that is human, after following the Edison incandescent light bulbs is one of the greatest inventions.
Five questions the existence of domestic LED industry
According to the national main road lighting standards drafters Tie-nan, China's "Green Lighting Project" Implementation began in 1996. An important step in achieving this plan is to develop and promote efficient, energy-saving lighting appliances, lighting electricity savings, reduce environmental and light pollution, the establishment of a high quality and efficiency, economic comfort, safe, reliable, environmentally friendly lighting systems. Particular, China in 2003 established the Working Group on semiconductor lighting, marking the government for the development of the field of LED for lighting high hopes, LED as the light source into the general illumination market as the core of future industrial development.
In the "National Semiconductor Lighting Project" to promote, Shanghai, Dalian, Nanchang, Xiamen and Shenzhen, have formed a semiconductor lighting industrial base. Yangtze River Delta, Pearl River, Delta, and north Fujian China's LED industry is a gathering place.
At present, China's LED industry has formed a relatively complete industrial chain, bought the device in experienced, buy chips, buy a wafer after the road has now achieved in the production of epitaxial wafers and chips. This stage, the number of people engaged in the industry reached 50,000 people, more than 20 research institutions, enterprises 4000; one upstream firm more than 50, more than 1000 packages, more than 3,000 enterprises downstream applications, and a batch innovation, skilled advanced enterprises.
However, late start, compared to European and American developed countries, domestic market size of LED industry or technology, whether there is a considerable gap. To sum up, mainly in the following five areas:
In the LED epitaxial wafers, chip production, compared with the international advanced level, domestic chip average brightness, luminous efficiency, anti-static capability, anti-leakage capabilities and there is still a wide gap between the level of quality control. Therefore, the core of our current high-power LED chips, especially chips rely on imports from the United States, prices remain high, medium and small companies were purchasing a single, very little bargaining power, cost a lot of pressure.
Lack of core patents, in particular, is the most crucial white, high-power LED light heat balance, durable and highly efficient phosphor and other patents, has been in Europe, America, Japan and monopoly, to suppress the development of our industry.
LED lighting has not yet developed national standards, only using traditional detection methods to detect sodium LED lights, but the two are essentially different. In addition, the application of standards across the difference, leading enterprises to open up markets across regions encounter strong resistance.
LED small domestic enterprises, most did not exceed 100kk / monthly production capacity (blue green). China's participation in upstream units (in particular, scientific research institutions) want to build their own capacity, but the initial phase of production is not large, the entire industry, scattered resources, not the size of enterprise can only be imported from the high price of a single chip, bargaining ability of low status, make the cost high.
As the price of LED lights expensive than traditional sodium, one-time investment, and made the courage to put local governments, resulting in the promotion of LED lighting applications in the domestic rate lagged far behind Western countries.
