Cree Sets New Efficiency Benchmark with First 200 lpw LED Luminaire Prototype
Cree, Inc. raises the performance bar again with the demonstration of the first 200 lumen-per-watt (LPW) LED concept luminaire, which is more than twice the efficiency of the best linear fluorescent luminaires. The latest Department of Energy (DoE) projections* had estimated that this level of luminaire efficiency would not occur until after 2020, but Cree’s latest innovation has made this possible six years sooner than projected. The prototype leverages Cree’s vertical integration with innovations in LED chips, optics, materials technology and novel system design to deliver unprecedented performance. Read more »

A Roadmap to Efficient Green-Blue-Ultraviolet LEDs
A Roadmap to Efficient Green-Blue-Ultraviolet LEDs Scientists at the U.S. Naval Research Laboratory (NRL) have suggested a method that could significantly increase the efficiency of green-blue-ultraviolet light-emitting diodes based on GaInN/GaN, AlGaN/GaN, and AlInN/GaN quantum wells. Their approach could enable advances in solid state lighting and the creation of low threshold lasers and high power light emitting diodes (LEDs). Their research is published in the January 25 and November 26, 2013 issues of Applied Physics Letters. Read more »

Scientists Build Thinnest-Possible LEDs and Find It To Be Stronger, More Energy Efficient
Scientists Build Thinnest-Possible LEDs and Find It To Be Stronger, More Energy Efficient Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy efficient. Read more »

Developing Phosphor-Free White Light from Nanopyramid LEDs
Developing Phosphor-Free White Light from Nanopyramid LEDs Researchers in China have used nitride semiconductor nanopyramid structures to create light-emitting diodes (LEDs) with spectra that are similar to those provided by ‘white light’ LEDs with yellow phosphors [Kui Wu et al, J. Appl. Phys., vol115, p123101, 2014]. The researchers are at the Chinese Academy of Sciences’s institutes of Semiconductors and Mechanics, and Tsinghua University. A similar CAS/Tsinghua team previously reported such devices, using a polystyrene nanosphere mask to make holes for selective-area growth of nanopyramids. Read more »

Significant Technical Progress - BluGlass Demonstrates Best Ever RPCVD (p-GaN) Light Output
Significant Technical Progress - BluGlass Demonstrates Best Ever RPCVD (p-GaN) Light Output Australian Cleantech innovator, BluGlass Limited, has announced today that it has been successful in demonstrating the best ever p-GaN light output using its propriety technology, Remote Plasma Chemical Vapour Deposition (RPCVD) on an MOCVD partial LED structure. This result is greater than a 10 fold improvement in LED efficiency over the first p-GaN demonstration data published by the company in December 2012, when the same measuring methodology is applied. This has been achieved by making significant improvements in addressing the ‘interface challenge’, a key technical hurdle that has been limiting the p-GaN performance demonstration in the past.
