LED lighting market will accelerate growth in the next year

At present every 1000 lumens of LED lighting cost about $7-10, with costs continued to decline, from 2011 to 2012, LED lighting market demand will accelerate development, estimated 2015, lighting costs per thousand lumens is expected to drop to $2-3, when the global light source will gradually change into energy-saving light source, and more than 30% of the energy consume. In recent years, the application of LED in all aspects showed a rapid growth trend, in which the two major applications of LED lighting, LED backlighting, the most attention. Although LED manufacturers are back light source for the main profit, but because of the lighting market is much larger than the size of the backlight market, LED industry chain related companies have been eager for a fight into the development and promotion of LED lighting products.

PHILPS (Philips Lumileds) said that the current LED lighting for every $1 can get 100-150 lumens, to reach every $1 U.S. Department of energy requirements of DOE can get 1000 lumens of the target, but also requires a lot of effort. The Philips Lumileds LUXEON RebEL 3000K color LED lighting products as an example, the drive current of 350mA at 85 degrees Celsius, Tj C, after the improvement, the company data value can reach a maximum efficiency of 220 LM /W. From the crystal grains of LED and Lei's point of view, EPISTAR (2448) general manager Zhou Mingjun pointed out that the chip package prices should be reduced to 500 lumens of $/1 to the U.S. Department of energy (DOE) targets. At present, EPISTAR has developed 160lm/w high voltage driver LED chip (HV LED), this will be the solution to help LED general lighting application development. The utility model has the advantages that the luminous efficiency is improved, the current is reduced due to the high voltage driving, and the heat dissipation problem is also solved. In addition, the new hybrid white LED crystal electric, achieve high efficiency 168lm/w and high color rendering technology in the laboratory data have been. As for how to reduce the production cost of LED, the Japanese Ulvac and Electronic Technology Research Institute Dr. Koukou semiconductor Beck Suu, Japan LED lighting market demand rapid expansion, attracting many LED lighting business investment, but the most urgent or manufacturers to reduce costs, and improve product brightness, luminous efficiency. In the process, can improve the part including PSS process, ITO deposition equipment, plasma etching (plasma etching) etc.. Veeco instruments (Veeco) MOCVD marketing director Li Jiayi stressed that the MOCVD yield and productivity is the development of the LED industry one of the most critical aspects of the progress of MOCVD technology, and effectively reduce the manufacturing cost of LED. Including the wavelength, brightness, forward voltage, respectively, to reduce the loss of production, as well as through the LED wafer cost sensitivity analysis, emphasizing the uniformity and repeatability of the product to ensure that the LED epitaxial production, etc..

Other applications market, lighting giant OSRAM Osram president and CEO Dr. Alfred Felder said, car LED market, due to the emergence of new type of LED light source, let the car factory and LED light source manufacturers can output more cooperation with creativity and variety of lights. At the same time, estimate the mini projector using LED light source (Pico Projector), by 2013 the market size will grow to more than 7 million.

LED lights, traffic lights market is also an important application field of LED. Lianjia photoelectric chairman and general manager Huang Fangyu said, in order to Chinese market as an example, 2009 has installed 250 thousand LED road lamps, Guangdong province in 2010, large-scale implementation of LED industry demonstration project, is expected to LED street lamp installed capacity will reach 450 thousand. Currently more than 200 cities in the United States have installed LED street lamps, and there are more than 100 cities will be a large number of LED street lamps.
