LED UPDATE By M. Nisa Khan, Ph. D. As president of IEM LED Lighting Technologies, Dr. M. Nisa Khan consults in the solid-state lighting industry and educates consumers about LED lighting. She has a bachelor's degree in physics and mathematics, and master's and Ph.D. degrees in electrical engineering. Email her at LED and OLED Lighting Markets Keep on Rising 2013 LED Professional Symposium attendees value market growth. L ighting and electronic displayindustry professionals continue their efforts to improve LED and OLED lighting technologies to create expanding uses and applications, but, in truth, the pursuit is a technological and competitive effort to overtake the marketshare of incumbent lighting products. LED-based products have enjoyed healthy, double-digit growth in recent years, but the organic light-emitting diode (OLED) market has lagged, although it's having success in the smartphone-display field. The two - LED and OLED - have different, unique advantages and, of course, challenges and, therefore, stand primary in the R&D labs for many companies and research institutions. This prevalence was most notable at this year's annual, LED Professional Symposium (LpS 2013) and Exhibition - a leading, international event that showcases the latest LED lighting technologies. LpS: Europe's leading LED conference More than 1,100 attendees from 34 countries enjoyed LpS 2013. The venue - Festspielhaus Bregenz, Bregenz, Austria - is popular for special events, operas and concerts. Event statistics detailed the attendees' interests: * Manufacturing companies (60%) * Distributors (10%) * Engineering and design services (8%) * Universities (5%) * Journalists, government officials and others (17%) Several points from one keynote presentation caught my interest: 1. Presently, lighting draws 14% of Europe's total energy consumption. 2. The projected European lightingmarket growth rate for the next decade is 7%. These figures contrast with the U.S. market where light-energy consumption is roughly 20% of the overall energy use, and it's expected to decrease in a few years, due to moreefficient lighting products and the use of daylight harvesting. I asked if these aspects (increasing efficiency and harvesting methods) were considered in the European market analysis. And, because the European lighting-consumption Samsung's 5.3-in., Super AMOLED Galaxy Note Android v2.3 Phone with 1,280 X 800 resolution. The phone is 9.65 mm thick and weighs 178 grams. 28 SIGNS OF THE TIMES / DECEMBER 2013 / percentage was significantly lower than the U.S. scenario, I also asked if this could be due to more efficient lighting - or if the percentage is off-balance because of the regions' high electricity usage in other applications - electric-powered trains and buses, heating, air conditioning or other applications, for example. In both instances, the speaker said such data was not available. The European Union's demography is diverse, and the low, 14% statistic may be affected by inadequate lighting in many areas - less light, less power consumption. Further, the inequality, and accompanying plan for supplementary light provisioning in many regions, may be the reason for positive lighting-use growth projections. Still, a thorough study would be useful, one that reveals how daylight harvesting, energy-efficient lamps and electronic-control systems could affect the European plan. LpS 2013 also comprised 46 talks from presenters who work and research around the world. The presentations were divided into 16 sessions: Light Sources I-IV; LED Future I; LED Systems I-II; Driver and Controls I-IV; Optics I-II; Thermal Management I-II; and Applications I. In addition, the symposium offered workshops on testing and standardization, 3-D system design and print technologies, computeraided design of LED and OLED systems, and LED qualification and reliability. More than 80 international exhibitors displayed innovations, products and services across the sold-out, 2,000-sq.-meter floor space. Numerous supply-chain vendors displayed both prototypes and products that encompassed materials, optical components, thermal solutions, drivers, software-design tools and measurement instruments.
