LED luminous efficiency of luminous intensity and a gradual increase, as well as light-emitting light color coverage of the entire visible spectrum, energy efficiency and practicality of the LED light source can be highlights, its applications have also been a large expansion. LED, especially high-brightness LEDs have been widely used in LCD backlight, indoor and outdoor big screen, optical communication light, traffic lights, landscape lights, car lights and gradually entering the street lights, interior lighting, traditional lighting applications.
LED is called the green light, with energy saving, environmental protection, long life, small size, fast response, good shock resistance, high color purity can be widely used in televisions, monitors, mobile phones and other backlight; automotive lighting; a variety of functional lighting, landscape lighting, commercial and residential lighting; advertisements, directions, traffic directions and other fields.
Compared with conventional light sources of incandescent and energy-saving lamps, with a long life, high luminous efficiency, light color purity, high stability, good security, no radiation, low power, earthquake resistance, hit, etc., known as 21 The revolutionary technology of the century a new era of solid light source.
LED as a fourth-generation lighting, with better indicators than the CCFL, LED backlight device as the LCD screen backlight is widely used in mobile phones, digital cameras and other portable electronics, laptops, netbooks, desktop monitors and LCD TV and other end products, the backlight field will be fully replaced the CCFL, LED demand growth in the short to medium term the biggest driving factor. The following is a LED light source, the three major market development Present and Future.
1, the lighting market
Environment of ever-increasing global energy crisis, environmental requirements, long life, energy saving, safety, green, rich colors, the miniaturization of semiconductor LED lighting has become increasingly important to the future direction of the lighting technology. The life of the LED, solid package, a solid structure, the life expectancy of 100,000 hours, the fluorescent lamp 10 times, 100 times that of incandescent lamps. In environmental protection, with LED instead of fluorescent lamps, to avoid the secondary pollution of the fluorescent tube rupture overflow mercury.
By Global LED technology leader in efforts to improve materials, processes and packaging technologies, high-brightness LED luminous efficiency and performance has been significantly improved, in addition to the traditional backlight and the display panel market, the high brightness LED began to indoor and outdoor general lighting automotive interior and exterior lighting, lighting, traffic lights and other new applications.
LED lighting in accordance with the function points can be divided into public lighting and consumer lighting. Public lighting in general, including street lights, traffic lights, tunnel lights; consumer lighting including commercial lighting (shopping malls, hotels, stores and other commercial buildings), office lighting, home lighting, hotel lighting, restaurant lighting, hospital lighting, residential lighting.
ITRI ??produced by the Center (IEK) statement on the \"LED Lighting Industry Development Forum\", the LED bulb (lamp) from 2010 began to accelerate to replace incandescent light gun, mainly in Japan as the most representative. Because of Japan\\ s policy of subsidies, higher local environmental awareness among consumers, as well as manufacturers cut prices to create a Japanese local LED bulb rapid market growth. At present, the LED bulb sales in the Japanese market share reached 19%, equal to the sale of every five power ball there is an LED bulb.
European markets were as expected after Japan, the LED bulb the next fastest growing market. According to EU estimates, Europe in 2012 to abolish the (disabled) incandescent bulbs, plus many European countries, like Japan, Italy, Hungary, Austria, Portugal, the United Kingdom, Ireland, etc., electricity than is even higher, but also to strengthen energy-saving LED bulb to replace the thrust of the traditional incandescent bulbs. Estimated that by 2013, the global penetration rate of LED bulb will be up to 10%.
In addition, one of the downlight is also the focus of LED lighting. Surveys for builders, according to the Japan LED Downlight is one of the products of most concern in the construction industry, modular and replaceable LED downlight product development trend. Manufacturers, including GE, Germany LBM have been developed for LED downlight products.
On the whole, instead of traditional light bulbs will be LED lighting within the next few years (at least until 2013) the largest application market. Individual applications, including display lighting, commercial and industrial lighting, outdoor lighting, interior lighting, light bulbs replaced, etc., will be the main market within the next few years, LED lighting.
Regional markets, North America remains the world\\ s largest LED lighting market with a market share of 40%, accounting for about 33% of European market, accounting for about 21 percent of the mainland China market, including Japan and other parts of the market share of about 6% . 2012 the global LED lighting market applications and architectural lighting, with the national policy to promote the global economy (especially emerging market-driven) growth, as well as LED production can continue to expand our technology growth to promote the product price decline, coupled with the expansion of the scope of application, expected 2013 LED lighting market will reach $ 13.7 billion, the size of the global LED lighting market in 2015 is estimated to grow to $ 28.8 billion.
LED lighting in accordance with the energy supply sub-divided into the traditional energy supply and energy supply in two ways. LED\\ s unique low-voltage power supply and low power consumption characteristics make the new energy LED lighting greatly with the utilization of solar energy to improve and costs decline, the promotion of energy saving and environmental protection, solar and wind based LED lighting market is developing rapidly in recent years, the solar LED lights used in the outdoor landscape lighting and traffic lighting. Solar-powered LED lighting is estimated to account for about 25% of the entire LED lighting market, with the development of the market and policy driven, 2013 is expected to account for more than 30% of the entire LED lighting market in 2010.
2, the backlight market
LED backlight small size backlight source, the size backlight and large-size backlight small size backlight is mainly used in mobile phones, MP3, MP4, PDA, digital cameras and camcorders; in size backlight for notebook computers , computer displays and monitors, etc.; large-size backlight is mainly used in the LCD TV. With the significant increase in demand of LED TV, LED monitor, as well as mobile phones and other consumer electronics products, the demand for LED backlighting is also growing.
