LED industry: backlight TV most profitable lighting prices need to be reduced

At present, LED display backlight market unpopular, which are in short supply in two years, the most profitable. The next 3-5 years, the LED industry will enter the golden age, but also means that competition intensifies, LED companies do not step up the optimization of the technology chain, can not achieve mass production, is bound to be eliminated. "Recently, in the 2010 Annual Conference of Jiangsu Province Institute of electronics, academician, China Academy of Sciences Department of physics of Nanjing University professor Zheng Youliao said, thinking the experts and senior executives of Jiangsu LED industry development.

LED backlight TV: the most profitable two years

LED is a semiconductor lighting, is a kind of new lighting technology to control the light-emitting chip, but also to establish the focus of the development of emerging industries in Jiangsu province. The light emitting device can directly convert electric energy into visible light, and has the advantages of low working voltage, high luminous efficiency, long service life, etc.. Compared with the traditional incandescent lamp and fluorescent lamp, the utility model can save more than 90%. And its life is 10 times the fluorescent lamp, incandescent lamp of the 100 times, in the environmental protection also avoid the fluorescent tube rupture overflow mercury pollution of the two. "In a medium-sized city with 300 thousand street lights, for example, if all of the LED lights, a year can save up to 300 million degrees," said Professor Zheng Youliao.

In fact, LED has penetrated into people's lives. Like the red and green lights, the streets of Nanjing and other major city outdoor large screen mobile phone, digital camera, and the backlight button, LCD TV LED backlight are using LED technology. Shanghai this year, the theme of the Museum of World Expo landscape lights, but also allows people to appreciate the LED to create a dream world".

At present, LED display backlight market unpopular, which are in short supply in two years, the most profitable. Professor Zheng Youliao said, compared to the traditional display backlight, LED backlight in clarity, color reduction capabilities and contrast has obvious advantages. It is understood that LED backlight LCD TV from the listing to the outbreak of the market only took a short year, currently including Hisense, Konka, including many domestic color TV manufacturers have increased the intensity of investment.

"Automotive lighting will be the next 3-5 LED huge application areas. Professor Zheng Youliao introduction, a LED bulb life of 5-10 hours to work 12 hours a day, you can work for 12-23 years. This means that the car can not change the lights for life.

LED lighting: cost reduction

Although the LED industry has a huge space for development, but the future will be opportunities and challenges coexist. The outstanding problem is the high cost. A traditional street lamp up to 2000 yuan, while the price of a LED street lamp is as high as 4000-8000 yuan. Professor Zheng Youliao pointed out that, because of this, the current promotion of LED lighting can not completely get rid of the various levels of government support.

"A LED lamp 300 yuan, you will buy it? "Jiangsu Electronic Institute responsible person, last year, a civil LED product promotion will they held in Nanjing Shanxi road square, although the price lower than the cost to the public, but the public still generally reflect the high prices, eventually sold only a small amount of LED flashlight and a LED bulb, promotion cold end.

Behind the high price of LED products is the lack of core technology. It is understood that, Jiangsu LED enterprises have hundreds, most concentrated in the package, the application of industrial chain in the middle and lower reaches of the upper reaches of the core technology is still very lacking. It is understood that China's LED chip based on imports from the United States, Japan, Germany, Korea and other places.

LED light effect has yet to be further improved. "Professor Zheng Youliao said, in addition, energy-saving fluorescent lamp and semiconductor lighting will be the two major energy-saving lighting, energy-saving lamps containing mercury pollution, and the LED lamp price is high, the two will compete in their respective development.

The next 3-5 years, LED industry will enter the golden age, but also means that the industry competition intensifies. Professor Zheng Youliao pointed out that Jiangsu enterprises must step up independent research and development, reduce costs, optimize the technology chain, a brand, grab the market in order to win in the future.
