Organic light-emitting diodes (OLEDs) can be used for TVs, computer displays, cell phones and PDAs. These multi-layered devices produce light by running an electrical current through a specially engineered host material into which light-producing phosphorescent molecules are embedded or “doped.” The technology also holds significant potential as a general area light source, creating the potential [...]

Philips Color Kinetics has been honored by the U.S. Department of Energy (DOE), receiving an award for “Significant Achievement in Solid-State Lighting Research & Development.” The award recognizes Philips’ progress on an 18-month project intended to produce a highly efficient LED PAR lamp. According to test results, the lamp being developed is already significantly more [...]

My earlier post about an artist using the Tweenbots as a vehicle to explore how people interact with space reminded me of the Target Breezeway project at Rockefeller Center in New York City, designed by Electroland, LLC, where visitors to a room connecting the top-floor observation decks are invited to interact with room surfaces through [...]

OSRAM SYLVANIA has opened an expanded clean room dedicated to solid-state lighting research and announced research and product development awards from the U.S. Department of Energy totaling nearly $2 million. “As the economic downturn threatens to slow the pace of green technology investments, I’m proud to say OSRAM SYLVANIA is steadfast in our dedication to [...]

“Designing with Light” is a studio course in the Design Department at UC Davis taught by Professor Michael Siminovitch, director of the California Lighting Technology Center. Students enrolled in the 2009 course design, develop and prototype a fully working LED-based lighting fixture for the Annual LED Luminaire Design Competition. Students use a development kit of [...]

Here’s a project story I wrote for Archi-Tech Magazine before it went digital, which I still find interesting to revisit. The photos appear to be a bit saturated on the web translation here, but you can still get a great flavor for the project. The project was initiated by the Bochasanwasi Shri Akshar Purushottam Swaminarayan [...]

San Francisco Mayor Gavin Newsom and PG&E recently demonstrated streetlights installed on Turk Street (between Taylor and Jones) in the Tenderloin District, networked using Echelon’s LonWorks technology. The new LED streetlights, remotely controlled and monitored, promise to reduce the city’s energy and maintenance costs while improving lighting quality and safety. Streetlights are among a city’s [...]

Cree, Inc. has launched the Product Characterization Tool, an interactive LED design tool that simplifies the task of translating nominal LED performance to real-world conditions. The online tool, accessible at Cree’s website here, allows users to easily characterize any XLamp® LED over a wide range of operating conditions, including drive current, flux bin, price and [...]
