TV backlight growth has slowed down, and cost issues, as well as a huge consumer awareness of the lighting market is still completely open, the led driver 120w industry is facing the most difficult time. CHINA SSL as the global semiconductor lighting the first major event, bringing together the global semiconductor lighting industry giants and top experts, has become an important platform for exchange of technical information products in the field of international semiconductor lighting. November 8-10, 2009, CHINA SSL2011 was held in Guangzhou, representatives from countries and regions in the world come together in three days, in-depth discussion in such a situation, government, industry, enterprises should think about how face meeting to pass out a lot of positive signals and inject a shot in the arm for the industry. And "cost reduction" is one of the key words of the conference, representatives of the different aspects of the industry chain, production process improvements, application of new technologies, as well as the whole industry chain modularization both in-depth discussions.
Present, in order to "winter" break out in the market, how to reduce costs, how to increase per dollar lumens is the most important. At the meeting, Philips, GE, Osram Long and other large international companies have put forward 10 years later to be reduced by 10 times the target Fujian IMC Optoelectronics Technology Co., Ltd. launched 8W 810 lumens and the whole light retail price of 39.8 yuan LED bulbs has also become a hot debate of the industry, which in some sense to stimulate the industry has been cost-troubled nerves. Current lighting market, LED Floodlight 80W in recent years to replace cheap light source is not likely, mainly because the purchase cost is still too high. GE believes that the drive for personal consumption price of around $ 10, while there are still some distance. Reduce the cost of a variety of factors, the chip is obviously the most important chip prices this year, with the enhancement of luminescence efficiency and the expansion of production capacity by 30% -40% decline, but there is still considerable space needs efforts.
To improve the light efficiency and large-size development
The proportion of chips in the LED Flood light 10W lighting, and technological monopoly links. Enhancement of luminous efficiency, large-scale development can make the costs are greatly reduced, effectively increasing the cost of LED Power Supply lighting products. Michael Holt, CEO of Philips Lighting Company, the performance of Philips products in 2020 will reach 200 lumens per watt, he said "The bigger the chip can achieve greater efficiency, but we do not have the closing ceremony of the General Assembly solution to the problem of high current, if they can maintain a high current and high efficiency, then we can achieve our goals. "
In order to improve production efficiency, more and more LED chip factory to accelerate into 4-inch and even 6-inch chip production capacity expansion. South Korea's Samsung in 2010 is mainly used 4-inch machine the amount of production LED Spotlight 30W , Philips Lumileds announced the mass production of 6-inch LED chip but also at the end of 2010. Epistar in Taiwan, AUO's manufacturers Lunda, also claimed in 2011 to further expand the 4-inch chip-chip production technology. This meeting, love to think strong R & D vice president Michael Heuken said in an interview with a reporter's question, "large-size substrate film is a development trend, while the 4-inch, 6 inch, 8-inch substrate is an inevitable trend. Love thinking stronger on November 8 launched a new MOCVD equipment - new specifications the CRIUS 19x4-inch? II-XL reactor, you can choose to use the wafers of any size from 2 inches to 8 inches, simply replace the graphite plate hardware does not require additional hardware or process adjustment. "
