Experts claim that the LED market is hottest and most profitable

"At present, the LED display backlight market is hot, these two years are in short supply, the most money can be made. In the next 3-5 years, the LED industry will enter the golden age, but also means that the competition will intensify, if LED companies do not step up Optimization of the technology chain cannot achieve mass production and it will inevitably be eliminated.” The day before yesterday, at the 2010 Academic Annual Meeting of the Jiangsu Institute of Electronics, Zheng You’an, a member of the Chinese Academy of Sciences and professor of Physics at Nanjing University Eminem (13) Yu? ? 17. What? Shake (2) What is the difference? ? Thinking of ED industry development.

LED-backlit TV: The most money earned in these two years

LED Chinese means semiconductor lighting. It is an emerging lighting technology that uses chips to control light emission. It is also one of the key emerging industries that Jiangsu Province has established. The light emitting device can directly convert electric energy into visible light, and has the advantages of low working voltage, high luminous efficiency, and long service life. Compared with traditional incandescent and fluorescent lamps, it can save more than 90%. Its lifetime is 10 times that of fluorescent lamps and 100 times that of incandescent lamps. It also avoids the secondary pollution of mercury spills from the rupture of fluorescent tubes. "For example, a medium-sized city with 300,000 street lights could save 300 million kWh a year if it were replaced with LED lights." Zheng You? Doctor's advice? />

In fact, LEDs have infiltrated people's lives. The red and green signals on the streets of major cities such as Nanjing, outdoor large displays, and the backlit keys of mobile phones and digital cameras, LED backlights for LCD TVs, etc. all use LED technology. The landscape lights of the theme pavilion of the Shanghai World Expo this year made people appreciate the “dream world” created by LED.

"At present, the LED display backlight market is hot, and these two years are in short supply. The most money can be earned." Zheng You? Medical doctor? What is it? Can you give me a good wine? The ED backlight has obvious advantages in terms of definition, color reproduction capability, and contrast. It is understood that LED backlight LCD TV from the market to enter the market outbreak of the period spent only a short period of one year, including the current number of domestic color TV manufacturers including Hisense, Konka, have increased their investment.

"Automotive lighting will be a huge application area for LED in the next 3-5 years." Zheng You? Doctor's advice? Recovery? ED lamps have a life span of 50,000 to 100,000 hours. They work 12 hours a day and can work 12 to 23 years. This means that the car does not need to change lights for life.

LED lighting: cost needs to be reduced

Although the LED industry has huge room for development, it will still face opportunities and challenges in the future. The outstanding problem is the high cost. “A trip to the traditional street lights is up to 2,000 yuan, while the price of one LED street lamp is as high as 4000-8,000 yuan.” Zheng? Doctor's advice? ? leech? What? shell? The promotion of ED lighting cannot completely get rid of all kinds of support at the government level.

"A LED lamp 300 yuan, you will buy it?" Jiangsu Electronics Association responsible person, last year, they had held a civilian LED product promotion in Nanjing West Road Plaza, although at a lower cost Public promotion, but the general public still reflects the high prices, eventually sold only a small amount of LED flashlights and a LED light bulbs, promotion will deserted.

Behind the high price of LED products is the lack of core technologies. This reporter learned that there are hundreds of LED companies in Jiangsu, most of which are still concentrated in the middle and lower reaches of the packaging, application, and other industrial chain. The upstream core technology is still very lacking. It is understood that China's LED chips basically rely on imports from the United States, Japan, Germany, South Korea and other places.
