At CES, the global consumer electronics show, energy-saving solutions have received much attention. As a key energy-saving technology product in the field of electronics, the application of LED has been â€œstandardâ€ at CES. Many manufacturers have introduced green TVs and projectors that use LEDs to significantly reduce energy consumption. For lighting equipment, some manufacturers also LED table lamps were introduced.
CES is a microcosm of global LED applications
In addition to the field of display and backlighting, in the context of falling upstream chip prices and improved luminous efficiency, the penetration rate of LEDs in the field of lighting has rapidly increased. DIGITIMESResearch, a professional research organization, estimates that after the 2012 LED industry, the general lighting market will start to replace LED street lights in many countries, and the annual price drop of LE D lighting will reach 30%. The share will be further increased to nearly 20%.
LED enters the full application stage
LED has become an energy-saving and environmentally friendly means in the context of the current energy crisis, the greenhouse effect and the deterioration of the ecological environment. At this CES, the reporter saw that many consumer electronics companies have specially demonstrated green product solutions. For example, a color TV company has demonstrated energy-saving TVs. Thanks to the full use of LED light sources, one TV can save energy in six months. 7.2 KW, carbon emission reduction of 5.6KG. LED application in the field of video display is already standard. In the field of lighting, there are also companies that use LED table lamps as a table lamp for promoting learning.
At present, large-scale lighting manufacturers such as NEC, Sharp, Toshiba, Matsushita, Hitachi, etc. have successively launched low-priced semiconductor lighting products, and many LED light bulbs can be seen in many electronic goods stores in Japan. Recently, Toshiba and Matsushita also plan to start selling straight-tube LED lights.
In the Chinese market, in 2010, large-scale advancement in chip production is a major highlight of China's LED industry. According to the LED inside analysis of the industry research institute, China plans to increase the number of MOCVD devices for LED devices in the next few years to over 1,200, of which more than 300 MOCVD plans are planned for 2010.
The expansion of production capacity accelerates the price reduction. According to the National Gold Securities Research Report, the improvement in light efficiency and price reductions have pushed LEDs into full-scale application. At present, the application of LED has entered various application fields such as display, backlight and illumination, and the comprehensive application stage has arrived. â€œAt present, the LED luminous efficiency has exceeded 100lm/w, and the price has dropped below US$5/w. It has already had large-scale commercial conditions.â€
Price has been a decisive factor in the extension of LED applications, from price-insensitive municipal landscapes to price-sensitive commercial backlights to general-purpose lighting, which is most sensitive to LED prices. Guojin Securities predicts that LED prices will soon reach commercial popularity requirements: the cost of 1000 lm luminous flux is less than 10 US dollars, and the luminous efficiency of warm LEDs per watt exceeds 100 lm.
Commercial lighting and display as a growth subject
Guojin Securities Research Report pointed out that commercial lighting and display will be the main growth factor of LED application in the future. In 2012, the global market will reach 9.2 billion, 11.2 billion US dollars, and the 3-year compound growth rate will reach 33% and 19%. The domestic market will grow faster. The annual increase of 39% and 23%. The reporter learned that the 2008 Beijing Olympic Games used hundreds of thousands of LED chips. By the 2010 Shanghai World Expo, the use of LED chips reached more than 1 billion.
The expansion of the LED market, especially the quotation of LED chips, has fallen sharply, which has brought development opportunities for downstream packaging and application enterprises. Lighting is expected to become a new important application field of the LED industry after TV backlight.
At present, LED lighting has become one of the major development policies in many countries. In 2007, Australia introduced the first ban on the use of incandescent lamps. The EU also passed regulations on the elimination of incandescent lamps in March 2009.
DIGITIMES predicts that LED bulb shipments will increase significantly, and the output value is estimated to be as high as about 8 billion US dollars. In terms of output value, the global LED lighting market will penetrate 10% in 2011. The agency also pointed out that after 2012, Under the influence of factors such as the annual replacement of LED street lights and the annual price drop of LED lighting by 30%, the global LED lighting output value penetration rate will further increase to nearly 20%.
