LED industry ushered in ten years of gold

From the infrared remote control to the mobile phone screen, from traffic lights to household appliances display, semiconductor light-emitting diode (LED) in our lives can be seen everywhere, and the trend of Industrial Economics Research Center (IEK) data show that in 2006 the global LED market size of more than 6 billion U.S. dollars, in 2007 and 2008 will maintain a growth rate of over 10% respectively, $6 billion 850 million and $7 billion 670 million. Moreover, the car headlights, laptop display and lighting as the representative of the high brightness LED, will replace the mobile phone display, home appliances and other low brightness LED, to become the driving force for the growth of the market size of the locomotive. It is estimated that in 2007 the high brightness LED will increase by 16%, while the general brightness LED and infrared LED growth were only -5% and 1% experts even claimed that along with the development of LED and brightness heat, assembly technology, "LED demand in the next ten years will not see any cloud".

Two breakthrough detonated high brightness Market

Due to the limitations of light-emitting efficiency, etc., and now LED commercial products are mainly mobile phone backlight. 2006 mobile phone backlight occupies 33% of the world's LED application market, IEK estimated market size of only $1 billion 760 million in 2007, in line with previous years. In this regard, OSRAM (OSRAMOpto) product manager Steffen Block said: "if 2003 to 2006 can be seen as LED lighting and mobile communication era, so after that, with the development of LED in automobile taillight, notebook computer, LED technology will enter the era of power, and the greater the future lies in the large-scale use of car headlights and lighting the. Expert analysis, in 2007, will be a turning point in the development of high brightness LED, with the release of the two major bottlenecks in technological breakthroughs and patents expire, high brightness LED will gradually enter the climax of the.

Technology, LED white light efficiency has been raised to the applicable scope, and mass production. The history of the development of Lumileds Lighting Roland Haitz company in 2003 on the basis of LED since 1965, commercial 30 years, summed up an empirical laws of technology about LED every 18 to 24 months after the brightness can be doubled, in the next 10 years, is expected to further enhance the brightness can be 20 times, and the cost will be reduced to the existing 1/10, which is known as Haitz's law, also known as LED Moore's Law (World Moore). According to this inference, with a breakthrough of the brightness of 100lm/W (100 watts per watt) of LED about 2008-2010 years. The actual situation is more optimistic, including the June 2006 LED industry leader - the Japanese company Nichia (Nichia) launched 100lm/W white LED engineering sample; June 2007 CREE announced that LED lighting brightness and efficiency of the new standard XLamp LED (minimum luminous flux under 350mA 100lm) production supply, these are high brightness LED wide ready for promotion.

Patents, mainly from Japan, Europe and the United States to master the LED patent from 2007, 2008, the patent expires in 20 years will be gradually lifted. In fact, the patent term approximation step by step, in order to avoid disputes on patent technology, including TOYOTA, Cree, synthesis of Nichia, Philip and OSRAM and other leading companies on the one hand, to maintain the monopoly to carry out mutual authorization, authorization, patent transfer "authorized OEM mode on the other hand with the BRICs manufacturers. And in the case of patent licensing, production opportunities to lower manufacturing costs in China, Taiwan and other regions, emerging LED manufacturers have also pulled into the traditional LED technology with large manufacturers.

High brightness LED market opportunities in notebook computers, automotive and lighting

IEK data show that the mobile phone LED backlight is the main stage application market, but with other needs, especially notebook computer, automotive and lighting, high brightness products increase, expected LED will be gradually reduced in the mobile product market share.

First of all, the luminous efficiency and reduce the cost of LED in small size panel (7~9 inch) backlight penetration May 2008 increased from 20% in 2006 to 50% in 2007, after taking LED as the light source of the notebook computer (10 inch) may significantly increase. Compared with the traditional cold cathode fluorescent tube (CCPL) back light source, saving space LED has 30% to 40%, continuous operation time of traditional notebook computer is only 3 to 4 hours, while the notebook computer LED backlight can reach 8 to 12 hours; in addition, the LED is more compact, the traditional notebook computer the weight of 1.5 kilograms, while the notebook computer LED backlight can be reduced to 1 kg; LED mercury is more adapt to the environmental standard, the latest news is that in order to make notebook computer more environmentally friendly, the pioneer apple is currently evaluating LED backlit LCD panel AU optical electronic and optical electronics to the CMO, LCD panel at present, all with LED backlight panel instead, and to abandon all the materials for mercury fluorescent LCD panel at the end of 2007.

Secondly, the application of LED in the automotive market will gradually warming, the market size in 2007 is likely to grow by about 18%, of which the external light source growth is particularly significant, an increase of more than 22% is expected to. In Japan and Europe, the permeability of the third brake light were as high as 40% and 85%, while in North America is only 20%, and about LED direction indicator in the three market penetration rate of only 10%, the market development space is huge. In addition, the application of LED in the headlights also open up the situation, Stanley electric (Stanley ELectric) and Germany (Hella KG H ueck&Co. Hella) LED module for the joint development of car headlights, estimated before and after 2008 will reach and exceed HID lamp now
