LED backlights tend to become hot spots for large-size LED street lights
After years of rapid development, influenced by factors such as the global financial crisis, the growth rate of China's LED market in 2008 has declined to a certain extent compared with that in 2007. It is expected that the growth rate of LED market sales in 2008 will only reach about 12%. . However, compared with other semiconductor products, due to the wider application of LEDs and less dependence on consumer products, the financial crisis has also had a negative impact on the LED industry, but its impact is relatively weak, and because LED has great potential in landscape lighting, street lighting, large-size backlights, automobile lights, etc., and its development prospects are still good.
From the perspective of LED market applications in 2008, LED indicators, LED displays, mobile phone keyboards and camera flashes, and LCD backlights rank among the top four sales areas. In terms of sales, LED displays, LED indicators, LCD backlights, and mobile phone keyboards and camera flashes are among the top four. Although these four fields occupy the mainstream position of the Chinese LED market, due to different factors, the development of these four major application areas in 2008 is still affected.
Although the development of China's LED market in 2008 encountered certain obstacles, its market growth rate has declined to a certain extent compared with that in 2007. However, LED has the advantages of green, environmental protection and energy conservation, which is in line with the international energy conservation and emission reduction development policy. The overall trend of the market in the future is still good. On the other hand, LEDs will be further developed in the emerging application markets such as large-size backlights, landscape lighting, automotive lights, and low-temperature lighting in the next few years, and will gradually become another booster for the development of the LED market.
Backlight market transition to large-size applications
LCD backlights and LED indicators have slowed due to the decline in output of the downstream machine manufacturing industry. The deepening of the global financial crisis has brought great impact to China's downstream machine manufacturing industry. In 2008, China's mobile phone production growth rate showed a significant decline compared to 2007, and its growth rate was only maintained in single digits. The sharp slowdown in the growth rate of mobile phone production has brought a big impact on the small-size backlight market, and the price of products has also dropped significantly.
As the small-size backlight market enters a mature stage of development, LEDs have gradually transitioned from small-sized products to large-size products. Laptops using LED backlights have emerged in the market, but due to the price of LED backlight modules and CCFL modules. There is still a big gap between them. The use of LED backlights will greatly increase the cost of the product, resulting in low penetration of LEDs in notebook computers, but LEDs rely on the planarization of the light source, a wide range of color gamut, Low product power consumption and thin and light features still have a lot of room for development in notebook applications. In addition to notebooks, LED replacement CCFL has become the backlight of LCD TVs and has become a new application highlight of LED. However, due to the impact of factors such as high development price and high product prices, CCFL will still occupy the mainstream position of the large-size backlight market in the short term. LED still has a long way to go.
Landscape lighting and LED street lights become hot spots for lighting applications
In terms of high-power products, LED is still a hot spot in the market for landscape lighting and LED street lights. At present, the penetration rate of LED landscape lighting products is gradually improving. The LED street lamps have been developed under the support of the government. However, due to the limitations of factors such as heat dissipation and light extraction efficiency, the market development is still in its infancy. . For LED products, 0.5W and 1W products will remain the mainstream application in the lighting market.
For LED lighting applications, the lighting application is still in a weak position throughout the application market. The main applications are still concentrated in the fields of landscape lighting, interior decoration, LED street lights, etc. It still takes a certain time for LEDs to enter the general lighting market. In recent years, LED street lights have gradually gained market attention. At present, local governments are actively promoting the construction of LED street lights. For example, at the end of 2008, Guangdong launched the Thousand Miles Plan and the LED Demonstration Project of Tianjin Polytechnic University. Although local governments are actively promoting the development of LED streetlight demonstration projects, as LED street lamps still need to be improved in terms of product stability, and the product prices still have a large gap with traditional products, the commercialization of LED street lamps still needs to be certain. time. In addition to LED street lights, low-temperature lighting has also developed rapidly in the global market in recent years, becoming a new niche market for LEDs. Products in the US, Japan and Taiwanese hypermarkets have LED low-temperature lighting products, although the market has not yet started in China. However, there are still broad market development prospects in the future.
In addition, LED car lights have also become a hot spot for market attention. At present, LEDs have been widely used in automotive interior lighting, and applications in emergency brake lights have gradually increased. At this stage, LEDs are gradually transitioning to automotive headlights, taillights and other products. Some models using LED lights have appeared on the market. LEDs show a trend from the inside to the outside and from the back to the front in automotive applications.
