LED technology matures over 500 billion market still need to be developed to support

In 1879, Edison invented the incandescent lamp, which marks the human lighting from the fire into the era of electric lighting. From the production of incandescent lamp has been more than 130 years, with the progress of science and technology, lighting source to the direction of more efficient energy conservation. In 1930s, Holland scientists have developed the first fluorescent lamp, based on 80s, and the development of compact fluorescent lamps than incandescent lamp has due to its advantages of energy saving, long life, and quickly occupied the market, has now entered the stage of phasing out incandescent lamp. Since 1940s, scientists have also developed a high strength gas with high pressure sodium lamp, metal halide lamp as the representative of the discharge lamp, because it has the advantages of high efficiency, high power density, which is widely used in outdoor lighting, road lighting and commercial lighting etc..

1960s, Hewlett-Packard Company's first production of red LED products. After nearly half a century of development, with light emitting diode (LED) semiconductor lighting, because of its low power consumption, long service life, fast response, small size, rich in color, dynamic control and other advantages, more and more widely used in indoor and outdoor lighting, large-size LCD backlight display screen, medical, transportation and other fields. As a lighting technology revolution after incandescent lamp, fluorescent lamp, opened a new era of lighting.

LED technology matures

At present, the developed countries accounted for about 20% of total electricity consumption, electricity saving potential is considerable. In today's world energy crisis, energy saving more and more pressure in the background, the main developed countries in the world from the national strategic height increase of semiconductor lighting support and attention, to give strong support in terms of policy, such as the development of semiconductor lighting technology and industry development planning, accelerate the high energy consumption of incandescent lamp light out plan, introduction demonstration application and promotion policy, attaches great importance to and actively promote the detection and standardization process, seize the industry leading power etc..

In 2010, the Japanese Ministry of economy "lighting LED lamp" included in the environmental protection system of integral support, and made clear that in 2015 LED lighting products market share reached 50%, to 2020, LED lighting products market share reached 100%. The South Korean government will be solar energy, semiconductor lighting, hybrid vehicles as the three engines of green growth, and proposed to the 2012 government office LED lighting product replacement rate reached 30%, the semiconductor lighting industry in 2015 to enter the world top three. The United States to the semiconductor lighting industry as an important starting point to revive the manufacturing industry. EU invested heavily in the development of semiconductor lighting common technology research and development platform. Policy support has become an important driving force for the development of semiconductor lighting industry.

From the industrial distribution, the semiconductor lighting industry is mainly distributed in Europe and the United States, Japan and South Korea, China, Taiwan and the mainland. LED as the main body of the semiconductor lighting industry chain, including chip manufacturing, device packaging and product application of the 3 links.

One of the most advanced technology, chip development in Europe and the United States, Japan and other developed countries, packaging applications are mainly distributed in South Korea, Taiwan and mainland china. With the accumulation of South Korea and Taiwan LED manufacturers in the technical and financial aspects, actively to the upstream epitaxial material, chip development, while in mainland China, due to huge market prospects, has become the hotspot of the global industrial transfer.

Since 2000, semiconductor lighting technology has entered a period of rapid development. 2011 white LED luminous efficiency has been more than 130 lm/W, an annual increase of 10 lm/W, is expected in 2015 will reach about industrial efficiency of about lm/W. At the same time, with the development of technology, the continuous improvement of luminous efficiency, the gradual expansion of the market, the price of LED lighting is also declining, the current price of 50-60 yuan /klm LED devices, to 2015 may be now down to 1/5. Semiconductor lighting technology and its products are higher efficiency, lower cost, more reliable and more diversified fields and wider application direction.

Power saving potential of semiconductor lighting

According to the data of the U.S. Department of energy Sandia National Laboratory, lighting energy consumption accounted for 8.9% of global energy consumption, electricity consumption accounted for 19%, the contribution rate of GDP is only 0.63%. If the general lighting are used semiconductor lighting products, lighting consumption in 2050 is expected to maintain the level of 2005, and the contribution rate of GDP will rise to 1.63%. The semiconductor lighting industry as a new industry, not only led to the development of related industries, and create a new market demand, while the popularity of its application will greatly reduce the power consumption of energy, energy saving.

China's total annual electricity consumption of about 500 billion kwh, accounting for about 13% of total electricity consumption, accounting for energy consumption of 6%, and the annual growth rate of 5%-10%, higher than the total annual electricity consumption in britain. At present, LED light effect has been much higher than the traditional lighting and display light source, showing a better energy saving effect, such as landscape lighting energy saving 70%, backlight energy saving 50%, road lighting energy saving 50%.

Experts predict that in 2015 if China's semiconductor lighting market share accounted for 30% of the general lighting market, the annual saving of about 100 billion kwh, reduce carbon emissions 98 million 990 thousand tons, as the unit GDP energy consumption reduced by about 1 percentage point contribution to 2020; if the market share accounted for 50% of the general lighting market, the annual saving of about 340 billion kwh that is equivalent to the annual total generating capacity of 4 Gorges project. In addition, compared with the current application of a large number of energy-saving lamps (CFL), semiconductor lighting products do not contain mercury, less waste, and the manufacturing process does not exist
