The seventieth session of the CEF conference presents LED hot

At the seventieth China Electronics Fair (CEF) held at the Shanghai New International Expo Center, there are more than more than 2 thousand and 200 suppliers from all over the world. Innovation and energy saving is an important topic of this conference, and as an important platform for the exchange of electronic industry, 14 events and meetings held over the same period has become one of the highlights of the audience's attention. Among them, LED, automotive electronics and RFID become the three hot spots of the conference.

LED boom continues to heat up

In 2005 and 2006, the global LED market turnover grew by only 2.1% and 8.7%, but the iSuppli's latest research report shows that in 2007 the overall LED market turnover will rise by about 13.7%, and 2006 to 2012 compound annual growth rate is as high as 14.6%. The report said that in 2012 the global LED market will reach $12 billion 300 million, large screen backlight and general lighting is to stimulate the growth of the two factors. The optimistic outlook for the LED market not only attracted a large number of international semiconductor manufacturers to enter this field, many local manufacturers have tried to seize this opportunity in the market before take-off, HC semitek, Jiuzhou optoelectronics are two good examples.

From Wuhan, China can provide full color display and lighting two series of blue and green LED epitaxial materials and chips. This is a 07 year in August has just officially put into operation of the enterprise, but its vice president Ye Aimin said that the goal can not be the same with many other local manufacturers. Allegedly, not only has the quality system management experience rich compound semiconductor industry background, and returned from the United States, Japan, Europe and Taiwan area technical team composed of the main business has also brought by the number, the field of LED core patents and advanced III nitride based high performance LED luminescent material growth, device design the core technology and manufacturing. Ye Aimin said, the company also has extensive growth, cleaning, lithography, evaporation, grinding, sorting the whole process line. And it is for this reason, we are not interested in low-end applications, but the technology is higher in the high-end market. He said.

In the field of product manuals, the Chinese can be listed in the 2 models of white light with the highlight of the LED chip and the use of LED blue and green chips with 6 parameters. Ye Aimin said that the white light with LED in the main index for brightness, and display with LED on the consistency of product life, antistatic ability, quality stability and higher requirements, HC semitek has a good solution to the challenge. White LED chip, for example, the use of ITO technology production of 12x12mil white chip HC-B1212IA has been with the mainstream level of the manufacturers in Taiwan equivalent brightness. The same series is scheduled for the second half of next year's mass production of 14x14mil white chip HC-B1414IA is to achieve the brightness of 7lm, which is comparable with the best products in Taiwan counterparts. He said.

Jiuzhou optoelectronics is a subsidiary of Sichuan Jiuzhou electric group LED electronic display and LED components manufacturers. The company has many years of LED display design, production and development experience. Currently in Shenzhen and Mianyang each has a LED packaging and high-power LED production base. Its products include a single lamp, SMD LED, high-power LED, dot matrix LED and digital LED. "We have the best dot matrix LED and digital LED technology in china. Li Feilong, general manager of the company's marketing, said.

Li Feilong said, Jiuzhou optoelectronics is very optimistic about the development of LED in the field of general lighting, but even in foreign LED lighting technology is still in the stage of improvement. The main problem is the heat dissipation and softness has not been resolved, resulting in life can not be guaranteed. In addition, the cost of LED lighting is now about ten times that of ordinary lighting, and can only be used in the newly built infrastructure and some upscale places in the developed cities. He also pointed out that China has no specific specifications and standards LED lighting, resulting in disorderly competition is not conducive to the development of local LED technology.
