Aledia Has Produced Its First Nanowire Chips on 300mm Silicon Wafers Using CEA-Leti Pilot Lines
Aledia Has Produced Its First Nanowire Chips on 300mm Silicon Wafers Using CEA-Leti Pilot Lines Aledia, a French startup pioneering a disruptive technology for microLED displays, today announced it has manufactured the world's first microLED chips produced on 300 mm (12") silicon wafers. The company, which developed its breakthrough technology on 200 mm (8") silicon wafers over the past eight years, will produce the chips on both 200 mm and 300 mm wafers. The larger wafers provide better economic payoff and cost-effective integration with smaller-node electronics, which are only available on 300 mm silicon wafers. Aledia was spun out of CEA-Leti, a French research institute pioneering micro- and nanotechnologies, in 2012, and the work on 300 mm wafers has been performed by joint Aledia and CEA-Leti teams.

Repro-light Consortium Concludes
Repro-light Consortium Concludes Aldrans, Tyrol, November 2020 - The European research project Repro-light concludes after a three year journey which began in 2017. The consortium set out with the aim of supporting the European lighting industry in moving towards a more sustainable and competitive future. The project harnessed innovative technologies and materials to develop intelligent modular luminaires with matching smart production processes. The main components of these luminaires are interchangeable and configurable for the respective application (e.g. different LED modules and optics), and their software can be updated accordingly. The LED luminaire can change from a disposable object, into a customisable and sustainable product, with a high function value. Read more »

Research Shows that Streetlights Contribute Less to Nighttime Light Emissions in Cities than Expected
Research Shows that Streetlights Contribute Less to Nighttime Light Emissions in Cities than Expected When satellites take pictures of Earth at night, how much of the light that they see comes from streetlights? A team of scientists from Germany, the USA, and Ireland have answered this question for the first time using the example of the U.S. city of Tucson, thanks to "smart city" lighting technology that allows cities to dim their lights. The result: only around 20 percent of the light in the satellite images of Tucson comes from streetlights. The study is published today in the journal "Lighting Research & Technology". Read more »

EurekAlert - Annunces: Impurities Enhance Polymer LED Efficiencies
EurekAlert - Annunces: Impurities Enhance Polymer LED Efficiencies New research published in EPJ B reveals that the higher-than-expected efficiency of PLEDs can be reached through interactions between triplet excitons, and impurities embedded in their polymer layers. Molecular dynamics simulations have shown that the mysteriously high efficiency of polymer LEDs arises from interactions between triplet excitons in their polymer chains, and unpaired electrons in their molecular impurities.

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 »

ALLOS and KAUST Are Working on High Efficiency Nitride-Based Red LEDs on Si
ALLOS and KAUST Are Working on High Efficiency Nitride-Based Red LEDs on Si ALLOS Semiconductors has engaged in a collaboration with Prof. Ohkawa and his team at King Abdullah University of Science and Technology (KAUST) for realizing high efficiency nitride-based red LEDs on large diameter silicon substrates. In the collaboration the teams are addressing fundamental issues like the large lattice mismatch and the quantum-confined Stark effect (QCSE) which are preventing the adoption of red nitride-based LEDs for practical industry usage. In particular, for the emerging field of micro LED displays there is a strong demand to enable red LEDs on large diameter wafers in addition to the established blue and green color LEDs in the nitride system in order to reduce manufacturing complexity and cost.
