New Family of Tiny Crystals Glow Bright in LED Lights
New Family of Tiny Crystals Glow Bright in LED Lights Light-emitting diodes, better known as LEDs, offer substantial energy savings over incandescent and fluorescent lights and are easily produced in single colors such as red or green commonly used in traffic lights or children's toys. Developing an LED that emits a broad spectrum of warm white light on par with sunlight has proven tricky, however. LEDs, which produce light by passing electrons through a semiconductor material, often are coupled with materials called phosphors that glow when excited by radiation from the LED. Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight. Read more »

Rensselaer Researchers Identify Cause of LED “Efficiency Droop”
Rensselaer Researchers Identify Cause of LED “Efficiency Droop” Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called “efficiency droop” that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to greater electrical currents. Efficiency droop, first reported in 1999, has been a key obstacle in the development of LED lighting for situations, like household lighting, that call for economical sources of versatile and bright light.

EU-Funded ManuCloud Project Combines OLED and Organic Photovoltaic in a Façade Module
EU-Funded ManuCloud Project Combines OLED and Organic Photovoltaic in a Façade Module The manufacturing of individually designed organic light-emitting diodes and solar cells and their combination can be realized in the near future. After three years the project ManuCloud (distributed Cloud product specification and supply chain manufacturing execution infrastructure), which was funded by the European Union, now successfully completed its work. As result the project partners Heliatek, Fraunhofer COMEDD, Tridonic Dresden and GSS Gebäude-Solarsysteme GmbH presented a demonstrator of a façade module, which combines the OLED- and OPV-technology. The objective of the ManuCloud project was the development of a service-oriented IT environment as basis for the next level of manufacturing networks by enabling production-related inter-enterprise integration down to shop floor level. Industrial relevance was guaranteed by involving industrial partners from the organic photovoltaic, organic lighting and automotive supply industries. Read more »
