LED casts a thousand beams. application prospect

, 2005 China LED market reached 11 billion 490 million yuan, driven by emerging applications market development

Driven by emerging applications market, in recent years, the rapid increase in the size of the LED market. 2005 China's LED production has reached 26 billion 210 million, the market size is exceeded 10 billion yuan mark reached $11 billion 490 million.

The application of LED has been developed from the initial simple electrical indicator, LED display to the LCD backlight, landscape lighting, interior decorative lights and other fields. As the LED has long life, no pollution, low power consumption characteristics, the future LED will gradually replace the fluorescent lamp, incandescent lamp as the next generation of green lighting source. To this end, the United States, South Korea, the European Union, China and Taiwan have developed a national semiconductor lighting program suitable for national conditions, and vigorously promote the LED lamp into the general lighting market. Indoor lighting will be the most market size and development potential of LED applications.

From a quantitative point of view, with the country's strong manufacturing capacity, the indicator is still a large LED use, the amount of consumption accounted for half of the LED market consumption. But because the light is more common after brightness LED, great production for many years and has formed a buyer's market, the market situation to pile up in excess of requirement prices continued to fall, seriously affected the market scale growth in the field of LED lights. LED indicator market size has maintained a single digit growth, but with the further decline in prices, LED indicator market size is difficult to maintain positive growth is expected from 2006 onwards, the market will show a negative growth.

1, the display market is the main market for LED apps, full-color display strong growth

LED display according to the use of the environment is divided into indoor display, outdoor display; according to the color is divided into monochrome, two-color and full-color display. LED full-color display by the RGB three color LED composition, each with a gray level of color, can display 16777216 colors, colorful, vivid image of the 256. LED full-color display can display a variety of colors of text, graphics, and can display images, 2D/3D computer animation, in particular, can display high-definition, colorful video dynamic image. With the above advantages LED full-color display is widely used in stadiums, municipal square, concerts, stations, airports and other places.

2, the small size of the mobile phone based backlight market slowdown, large size, especially the 7 inch backlight will become a new focus

LED has long been used in mobile phone based small size LCD panel backlight market, the continued growth of mobile phone production led to the rapid development of the backlight market. Especially the 2003 mobile phone is to promote the rapid development of white LED market. However, with the steady growth of mobile phone production stage as well as technical upgrading led to a reduction in the number of mobile phone LCD backlight LED, making the LED in the mobile phone backlight consumption growth slowed.

7 inch LCD panel backlight using the LED number is about 30 or so, far less than hundreds or even thousands of stars with the amount of LCD TV, and the difference between CCFL in Korah to around 20%. At the same time the color saturation of LED can reach 75% compared with CCFL of 104%. In the narrow gap, the double positive factors of high color saturation, 7 inch LCD backlight market has become the first choice for the development of large-size Backlight Market Entry point.

3, car light market potential, but the domestic market is difficult to start in the short term

Statistics show that in the car traveling at 100 kilometers per hour, equipped with LED brake lights than the vehicle is not equipped with LED brake lights brake distance will be reduced by 7 feet. Currently, LED has been gradually applied in the car's third brake lights. Although LED is still faced with low wattage lumens, $/klm units and related high policy constraints, in the automotive market taillights and headlights still need some time, but with the cost performance ratio decreases and enhance the luminous efficiency, the final LED will gradually realize the transfer from the car to the front, rear, and ultimately occupy the entire automobile market. With the huge production capacity of the car, LED car market is facing great potential for development.

In addition to the above problems, the development of the domestic LED auto lamp market is also facing other problems. As the domestic auto manufacturers mainly to foreign enterprises, the production of models are mainly foreign car models of domestic improvement. This directly led to the original vehicle design concept, the core technology of integrated vehicle systems are in the hands of foreign manufacturers. The car design is a coherent whole, each link changes will affect the vehicle electrical design changes. At present, the domestic automobile mainly low-end cars, car is also more mature foreign models, these models did not consider the use of LED time early in the initial design, but due to the lack of overall domestic manufacturers the core technology support, manufacturers are difficult to directly change the design of automotive lamp, affect the development of the domestic auto lamp market.

4, the gradual expansion of the indoor decoration lamp market, traffic lights replace the peak of the market will enter a period of rapid growth in the past

After years of replacement work, the country's major cities by the traditional traffic lights replaced LED traffic lights work is nearing completion. With the completion of the replacement work, LED traffic light market will not continue to maintain rapid growth, is expected in 2006 LED traffic light market is only 5.8% growth.

5, the Olympic Games, World Expo led the rapid development of landscape lighting market, the market growth in 2007 reached the peak

Landscape lighting market mainly in the streets, squares and other public places lighting decoration, mainly to promote power
