LED will extend to the field of general lighting

LED market size continues to expand, in 2004 the phone is still the main application areas of high brightness LED

2001 China LED market is small, but by the blue light LED market boom in 2002, China LED market growth. 2002 China LED market sales reached 7 billion 130 million yuan, an increase of 86.6%. Since then, the market still maintained a rapid growth rate, in 2003 China's LED market grew by 26.6% compared to 2002, reaching $9 billion 30 million. 2004 China LED market sales of 11 billion 510 million yuan, an increase of 27.5%.

From the point of view of the materials used in LED, the number of LED produced in domestic AlGaInP material is larger than that of GaN. 2004 domestic production of AlGaInP as the material to reach 1 billion 840 million, an increase of LED, the production of GaN as the material of LED was only 390 million, an increase of 25.8% in.

From the application of the market structure, the main application of LED includes display, mobile phone, indicator light, LCD backlight, lighting, decorative lights. The display market in 2004 sales of 2 billion 720 million yuan, up 12.9%, accounting for 23.6% of the market Chinese LED; mobile phone with LED sales of 1 billion 850 million yuan, up 29.2%, accounting for 16.1% of the LED market Chinese; indicator market sales of 4 billion 620 million yuan, up 34.7%, accounting for 40.1% of the market China LED, LCD backlight market sales of 1 billion 540 million yuan, growth 27.3%, accounting for 13.4% Chinese LED market. Lighting market sales of 230 million yuan, an increase of 43.8%, accounting for of China's LED market, decorative lamp market sales of $380 million, an increase of 35.7%, accounting for China's LED market of 3.3%. In the application, the indicator light is the main field of application, but the use of LED as a general indicator for the general brightness LED, only in the traffic signal lights or road lights and other outdoor lights with high brightness LED. In the application of high brightness LED market, the phone is still the most important application areas.

Overall, the current domestic market demand for the display market, domestic manufacturers occupy a dominant position. Mobile phone and small size LCD backlight source to become the main force driving the development of the 2004 semiconductor lighting market, which is mainly due to the growth of consumer products driven by the needs of small size LCD backlight LED. The demand for traffic lights is expanding. Landscape lighting has become a new force in semiconductor lighting. At this stage, for the lighting of LED is also very small, this is mainly because the stage of the LED luminous efficiency, color, light and other basic parameters do not fully meet the requirements of the traditional lighting parameters, but due to the two luminescence tube has many points and the government promulgated the "National Semiconductor Lighting project" etc. the support of relevant policies, I believe that over time, the progress of technology, LED will gradually replace the incandescent lamp, fluorescent lamp and other traditional lighting sources become a new type of green lighting source. Semiconductor lighting market has great potential for development.

With the application of LED in the mobile phone is becoming more and more common, especially with camera function of the mobile phone market accounted for the proportion of the total production is increasing, as the white light flash LED demand for rapid growth. In addition, the safety lights, microscope lights, flashlights, special white light and other small power white LED lamps have also entered the market. Therefore, this year, the rapid development of white LED market has become another important force in the market.

With the continuous development of semiconductor lighting technology, more and more LED into the field of lighting. Such as landscape lighting, building exterior lighting and some auxiliary lighting. In particular, LED lawn lights, traffic lights, flashlights, floor lights, landscape lights, underwater lights, buried lights and other products continue to enter the market, making the market for LED, especially the high brightness LED demand continues to expand. High brightness LED market entered a period of rapid development.

The next 5 years, the application of LED will be further expanded, further into the automotive, indoor and outdoor lighting and other fields

In the next 5 years, LED as the next generation of new lighting source will enter into a wider range of industries, such as automotive, large-size LCD backlight, indoor, outdoor lighting, LED applications will become more common. And LED as a new generation of lighting in the lighting market in the proportion of the market will show a trend of increasing year by year.

LED as the most important part of the car is the brake light, which is mainly because the LED lamp has a short response time, usually LED response time is 60ns, the response time is generally 140ns. The use of LED lights can reduce the incidence of traffic accidents. In addition, due to the impact of LED, easy maintenance, energy saving and other features, LED lamps can also be used as car headlights, taillights, steering lights and other automotive lighting and automotive dashboard light.

On the whole, LED is a very broad market for automotive lamps. At present, some high-grade car the United States, Japan and Europe have begun to use semiconductor lighting, but because the car in the field of high barriers to entry, so the car with LED lights at home has not been entered into the market, I believe that with the continuous development of the domestic auto industry, automotive LED lamps will be used in the next few years widely in the domestic car in the market.

For LCD backlight, although the LED has been used in the LCD backlight source, but the use of the scope of the main focus on small size LCD backlight. In the large and medium size LCD backlight market is still dominated by CCFL. Although the CCFL has the characteristics of linear light emitting and uniform light source, it has high power consumption and no environmental protection. Compared with LED, it has the advantages of low cost, low power consumption, long life, short and thin, environmental protection and so on
