The market research institute LEDinside per 1,000 lumens of LED lighting prices and costs about $ 7-10 dollars, as costs continued to decline since 2011-2012, the LED lighting market demand will accelerate its estimated 2015 per thousand lum ens of lighting costs are expected to drop U.S. $ 2-3, when global light source will be changed into energy efficient lighting, energy consumption and save more than 30%.
In recent years, LED in all aspects of the application showed a trend of rapid growth, especially LED lighting, LED backlight, and two applications most attention. LED manufacturers are backlight for revenue and profits the main force, but the lighting market size is much larger than the market of the backlight LED industry chain manufacturers have been gearing up to put into the development and promotion of LED lighting products.
Philips Philips Lumileds LED lighting for every $ 1 about availability of 100-150 lumens to achieve the goal of the U.S. Department of Energy DOE requirements for every $ 1 of 1000 lumens, you also need a lot of effort. Philips Lumileds LUXEON Rebel 3000K color temperature LED lighting products, for example, current drive 350mA, Tj 85 degrees Celsius C improved, the curr ent study on data values ??can reach 220 lm / W efficiency.
From the point of view of the LED epitaxy and grain, the Epistar Zhou Ming Jun, general manager pointed out that the chip package price should be reduced to 500 lm / $ 1, in order to achieve the goal of the U.S. Department of Energy DOE. Epistar 160lm / w high-pressure-driven LED chip, the HV LED, this will help the application development of LED general lighting solutions. Not only luminous efficiency, so that under a high voltage drive current is reduced, so heat issues better solve, plus without the converter, you can use the AC drive. In addition, the crystal the new hybrid electric white LED, in the laboratory data has been reached 168lm / w, high luminous efficiency and high color rendering index.
As for how to reduce the cost of LED production, the Japanese the Ulvac excellent Baker Semiconductor Electronic Technology Research Institute director Dr. Koukou Suu, the rapidly expanding Japanese market demand for LED lighting, attracting many LED lighting businesses to invest, but the firms most urgently to reduce costs, as well as to improve the brightness, luminous efficiency. Process to improve the part of the PSS process, ITO deposition equipment, plasma etching, plasma etching.
Marketing Director of Veeco Instruments VeecoMOCVD Li Jia also stressed that the MOCVD production and productivity is one of the most critical link in the development of LED industry MOCVD technology advances reduce the manufacturing cost of the LED. Including to reduce yield losses in terms of wavelength, brightness, forward voltage, and through the LED wafer cost sensitivity analysis, the emphasis on product uniformity and repeatability, to ensure that the LED epitaxial production.
Other application markets, lighting maker Osram Osram, president and chief executive Dr. Alfred Felder, mentioned, automotive LED market, the emergence of a new type of LED light source, so that the depot and LED lighting manufacturers can cooperate output with creative, as well as a variety of lights. Estimated using the micro projector, the Pico Projector, LED light source, to the 2013 market size will grow to more than seven million units.
LED street lights, traffic lights market is LED applications. Huang, Fang Yu said the Chinese market, for example, 2009 has been the installation of 250,000 LED street Guangdong Province in 2010, large-scale implementation of the LED industry, demonstration and extension projects, LED street light installation is expected to reach 45, chairman and managing director of EOI , 10000. The United States has been to over 200 cities trial installation of LED street lamp, and more than 100 cities bulletin will be the bulk purchase of LED street.
