Analysis of potential development direction of LED lighting

LED has been recognized by most people, most people are optimistic that the new generation of lighting sources in twenty-first Century. According to the current forecast to around 2010, may be close to 50lm/W light effect was so much hype. However, after all, a single power of about 0.1W, so the luminous flux is very limited. At present, it is necessary to integrate a lot of LED in order to make a new light source to replace the incandescent or compact fluorescent lamps, lamps, wall lamps and other lamps, these examples have been a lot of. But the high price, it is difficult to promote, to achieve a reasonable price of the era seems to have to wait for some time.

So in addition to a large number of traffic lights, emergency lights, whether or not what it is not the function? The United States LD+A 7 this year published a message: the advantages of using the LED control voltage is very low and simple control method, it will be installed in the indoor ceiling or made large lighting, through the computer output signal directly switching triode to control it. Due to the use of the computer, the number of LED can also be more convenient to control, to get a variable color when the variable color colorful lighting effects, and has been successful cases. For example, in the United States, "Rainforest Cafe" made a color changing color ceiling, in the Hollyword made a large color art.

Of course, will be a lot of LED together to make a lamp to make signs, marking the line is also a common application of the technique. Each of the 100 red LED lights at the top of the support bar at the top of the Millennium palace in the UK is composed of red.

According to a U.S. forecast shows that within 5 years the global LED market will grow from $3 billion 200 million in 2004 to $5 billion 600 million in 2008.

2006 after the high brightness LED - especially ultra high brightness LED (also known as UHB - LED), sales growth is bound to be extremely alarming. HBLED to 2008 revenue is estimated to reach $2 billion 640 million, while the UHBLED is expected to account for the global LED market 22%.

General lighting will be the mainstream of the future, is expected to reach $844 million in 2008. Is expected next year will be an important key to the development of LED. At present, the standard and indicator LED accounted for the bulk shipments though, but the future of HBLED and UHBLED will appear significant revenue.

The report concluded that, in the next 5 years, automotive, signal light and backlight applications will account for market sales of 60%. Ultra bright LED development speed over 50%.

According to reports, the ultra-high brightness LED market was $1 billion 200 million in 2001, the market was about $1 billion 600 million in 2002. Domestic LED industry is also in the stage of rapid development, more and more companies to invest in China LED.

It is understood that the domestic LED industry unit of more than 400 (excluding foreign), employing more than 50 thousand people, including technical staff of more than 5000 people. 2002 LED output of more than 15 billion, the output value of more than $8 billion; in 2003 LED output value of more than 10 billion yuan, output of about 20 billion, of which there are billions of ultra-high brightness LED. In recent years, the development speed of LED is more than 30%, of which the development rate of ultra high brightness LED is more than 50%.

At present, LED lighting products, has a stable of three consumer groups: the first major consumer groups are engineering company, to provide lighting design and production of personalized engineering; second consumer groups are industrial enterprises, industrial development needs special LED, applied to the products; third is the domestic lighting brand, oem. Of course, also includes the international lighting brand oem.

LED industry is a sunrise industry, but there are many problems. One is the technical foundation is relatively poor, the lack of core competitiveness, and there is a gap between the international market; second, the lack of industry standards, LED lighting product quality inspection standard, market sales of the product quality is uneven, leaving hidden dangers of consumer rights; thirdly, conventional products, technology products have matured into a vicious price competition trend in, blindly reduce the cost on the basis of neglecting the research and development of new products, leading to the development of the whole industry is restricted. Future changes LED industry, will be with the technology to solve the bottleneck of high power LED products in the lighting industry, once popular, will replace the traditional light source, triggering a revolution in lighting industry. At the same time, with the growing development of the LED industry, the gradual increase in competition, LED industry reshuffle day will not be far away.

From the current LED application industry division, high-end display, traffic lights, car lights, backlight; in the end is the home light source, outdoor lighting, solar products, toys and other low-end products. We choose the end of the lighting industry, mainly in the export market, for example, in the development of a floor lamp products there are many products: such as the square, sidewalks, underground parking, walls, ceilings, etc.. At present, a lot of companies choose some low-quality LED for LED lighting, which is very wrong, there are many engineering quality problems. Because the real meaning of LED is that it has a long life.

It can not be denied, LED has the advantages of other light sources can not be compared, but now the LED market competition is very intense, LED enterprises are facing the situation of price competition, regardless of the quality of the phenomenon has occurred. LED manufacturing enterprises only pay attention to quality has the opportunity to remain invincible.
