By 2014 expansion of domestic chip manufacturers will turn over or turn

Continue to penetrate the LED lighting industry, LED chip market demand is also rising. In July this year, HC semitek (300323) and poly photoelectric has released the construction of the first half of 2014 performance report, the net profit expected by 185%-215%, the net profit expected by 247%-270%. And market demand is still expanding, the second half of the net profit is expected to rise. In August 6th 30 billion, Toshiba plans to invest ~500 billion yen to make inroads into the white LED business purpose is to increase market share by expanding the scale of production. In the global LED chip sales list, Japan Nichia, American CREE and German OSRAM moved to the top, the top ten only China Taiwan EPISTAR and feedback on the list, the mainland manufacturers have a space for one person. This year, LED chip market has been swept away a few years ago the doldrums, continued strong demand for the situation so that the domestic chip ushered in the best opportunity to turn over ". But in the high attitude in the face of foreign brands in the domestic LED chip market overbearing, domestic LED chip manufacturers how to counterattack, how to "stand up"? To improve the technology strength is narrowing the gap between the best "weapon" as everyone knows, the chip is the core component of LED. But the Chinese chip, the impression has always been heavy production is not heavy quality. At present, the key lies in the development of LED chip technology and wafer substrate material growth technology. Now the mainstream substrate materials on the market are sapphire and silicon carbide, but the price of these two materials are very expensive, and are monopolized by foreign large enterprises. In order to break the international patent barriers, China research institutions and enterprises have started to study the LED on silicon substrate. Because the price of the silicon substrate is much cheaper than that of sapphire and silicon carbide, the larger size substrate can be produced, and the utilization ratio of the MOCVD can be improved. But the problem is, high quality silicon and gallium nitride is combined with the technical difficulties of LED chip, a huge mismatch in lattice constant and thermal expansion coefficient and the density of defects caused by the high and long crack and other technical problems hindering the development Chinese chip field. In addition to crystal energy in 2011 to achieve the success of 2 inch silicon substrate GaN based high-power LED chip production, the Chinese chip companies in the silicon substrate GaN based LED research has not been a major breakthrough. But in foreign enterprises, OSRAM, the United States, Japan and other Shamuke Puri first-class enterprise has made a major breakthrough in the study of GaN based LED large size silicon substrate. Among them, in 2011, the United States Prichard developed high-efficiency GaN based LED on 8 inch silicon substrate, made with the luminous efficiency of 160lm/W sapphire and silicon carbide substrate on the LED device performance comparable to the top level; in 2012, OSRAM produced 6 inch silicon gallium nitride based LED. So China LED companies want to expand their own third of an acre in the LED market, improve their own strength is a pressing matter of the moment. Seize the opportunity to accelerate the expansion, LED brand layout in recent years, LED enterprise brand publicity through various opportunities consciousness is more and more intense, LED lighting has entered the era of "brand building". The establishment of the brand, not by a plan, a package, a concept shortcut, but the need for long-term adherence, adhere to quality, adhere to the service. In order to establish the brand image and brand publicity products, establish Lighting Enterprises Direct stores, LED lighting experience hall, the carrier is more intuitive, really promote their own LED lighting products. Especially in the large enterprises have the layout of the channel era, dealers are also more willing to choose the brand, good quality and good reputation of the product, the brand has become one of the important factors that enterprises can successfully open the agent market. But the brand building is a lasting process, like wine, which also requires LED Lighting Companies in the brand building on the long-term efforts to increase. Comprehensive, in 2014 LED market "thirst" demand, domestic LED enterprises ushered in the best opportunity to get rid of "supporting" label. If you can go further in technology, no doubt the establishment of brand awareness will play a significant role in promoting. At that time, the domestic LED chip in their own site, turn over the call is not the Arabian nights!
