A New LED Controller Technology to Expedite the Next Level of Smart Lighting
A New LED Controller Technology to Expedite the Next Level of Smart Lighting Lighting installations that use artificial lighting and often deemed more comfortable and energy efficient are generally referred to as "Smart Lighting". While no clear definition exists "Smart Lighting" has become a common catch phrase. Kurt Marquardt, Senior Director LED Lighting Systems and Product Marketing, Infineon Technologies has a more accurate definition. For him, the term "smart lighting" describes the capability of the lighting system to adapt automatically to the needs of the users and the room. He presents an alternative way to implement smart lighting systems, using the new XDPL8221 digital LED-driver IC [1]. Read more »

The Adverse Ecological Impacts of Light Pollution: LEDs' Role in Mitigation
The Adverse Ecological Impacts of Light Pollution: LEDs' Role in Mitigation With the negative effects of artificial light at night on ecosystems increasingly well-understood, attention is now turning to the ways in which these impacts can be mitigated through uptake of novel technology and lighting strategies. Dr. Callum J. Macgregor, post-doctoral research associate at the Department of Biology of the University of York, and Dr. Darren M. Evans from the School of Natural and Environmental Sciences of the Newcastle University, discuss the current evidence for costs and opportunities associated with uptake of LED lighting and highlight important directions for future investigation.

Temperature Profiling of Secondary LED Optics by Infrared Thermography
Temperature Profiling of Secondary LED Optics by Infrared Thermography Over the last few years, the power density of white LEDs has increased dramatically. Whilst there are large efforts to optimize the thermal management and thus the temperature stability of the LEDs, less attention is paid to the temperature of the secondary optic. Peter W. Nolte, Franziska Steudel, Bernd Ahrens, Nils J. Ziegeler, Frank Drees, Horst Rudolph, and Stefan Schweizer from the Fraunhofer Application Center for Inorganic Phosphors, the South Westphalia University of Applied Sciences, and the Innovations-and Technologycenter GmbH, TRILUX Group respectively, have approached this issue. They investigated the temperature profiles of polymethyl methacrylate (PMMA) and polycarbonate (PC) secondary optics and they discuss the results. Read more »
