However, no standards exist that would allow interoperable use of luminaires, sensors, and controllers from different vendors. http://www.ledsmagazine.com//features/9/2/6 Sat, 04 Feb 2012 19:02:00 http://www.ledsmagazine.com/features/9/2/5 Relative to visible LEDs, UV LEDs are a quiet market at only $30 million, yet recent breakthroughs in radiant power and intensity have enabled the displacement of mercury-vapor lamps in applications including UV curing and counterfeit detection, reports LAURA PETERS. http://www.ledsmagazine.com//features/9/2/5 Sat, 04 Feb 2012 18:02:00 http://www.ledsmagazine.com/features/9/2/12 Requirements for LED processing equipment are changing from cost driven to more technology driven decisions, a clear trend to more complex and more efficient manufacturing, according to Thomas Uhrmann and Thorsten Matthias of EV Group. http://www.ledsmagazine.com//features/9/2/12 Fri, 03 Feb 2012 22:02:00 http://www.ledsmagazine.com/features/9/2/11 Work on a new and improved measure of color-rendering quality has apparently stagnated in the CIE, and the failure leaves the broad lighting community without a tool that would be very useful, says MAURY WRIGHT. http://www.ledsmagazine.com//features/9/2/11 Wed, 01 Feb 2012 22:02:00 http://www.ledsmagazine.com/features/9/2/9 To conclude our series of articles on LED photobiological safety, LESLIE LYONS puts IEC62471 to work in consideration of the hazards posed by today’s LEDs and LED-based products. http://www.ledsmagazine.com//features/9/2/9 Wed, 01 Feb 2012 21:02:00 http://www.ledsmagazine.com/features/9/2/10 MR16 sockets present a significant retrofit-lamp opportunity for LEDs, explains KAMAL NAJMI, but installed transformers complicate the design of a drop-in SSL replacement. http://www.ledsmagazine.com//features/9/2/10 Wed, 01 Feb 2012 21:02:00 http://www.ledsmagazine.com/features/9/2/7 A ceremony has been held to mark the first phase of a project to install LED exterior lighting at one of Europe’s great art museums, writes TIM WHITAKER. http://www.ledsmagazine.com//features/9/2/7 Wed, 01 Feb 2012 20:02:00 http://www.ledsmagazine.com/features/9/2/4 Now that procedures are in place to make long-term lumen-maintenance projections for LED components, efforts are being made to develop methods for testing the lighting system as a whole, as JIANZHONG JIAO explains. http://www.ledsmagazine.com//features/9/2/4 Wed, 01 Feb 2012 18:02:00 http://www.ledsmagazine.com/features/9/2/2 A Green Paper on LED- and OLED-based lighting published by the European Commission launches a period of public consultation on the future development of SSL in Europe, as TIM WHITAKER explains. http://www.ledsmagazine.com//features/9/2/2 Tue, 31 Jan 2012 18:01:00 http://www.ledsmagazine.com/features/9/2/1 The February 2012 issue of LEDs Magazine is now available. http://www.ledsmagazine.com//features/9/2/1 Thu, 26 Jan 2012 21:01:00 http://www.ledsmagazine.com/features/9/1/4 This webcast will explain the marketing and promotional benefits for winners of the Lighting for Tomorrow competition. http://www.ledsmagazine.com//features/9/1/4 Tue, 24 Jan 2012 19:01:00 http://www.ledsmagazine.com/features/9/1/3 The January 2012 issue, the annual LED Suppliers Directory, is now available. http://www.ledsmagazine.com//features/9/1/3 Thu, 12 Jan 2012 18:01:00 http://www.ledsmagazine.com/features/9/1/2 Strategies in Light 2012 will feature many educational functions including trade discussions with US Department of Commerce personnel and five tutorials that offer continuing education credits, writes Vrinda Bhandarkar. http://www.ledsmagazine.com//features/9/1/2 Tue, 10 Jan 2012 15:01:00
