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 »
