Cree, Inc.’s new XLamp® XB-D LED delivers twice the lumens-per-dollar of other LEDs, in a small lighting-class footprint of 2.45 mm x 2.45 mm. The XB-D LED is 48 percent smaller than the XLamp XP package and ideal for lighting applications where high lumen density and compact light sources are required. The XB-D LED uses up to three times fewer LEDs, three times fewer optics … [Read more...]

Wireless Shortcut to Avoid Data Center Traffic Jams
To better handle data center congestion, researchers are testing a shortcut that doesn’t involve costly rewiring. They are experimenting with wireless links, mounted atop the server racks, to supply extra bandwidth for moving data along at crunch times. The Microsoft team forged ahead with the project, building and testing a system with tiny directional antennas at the top of … [Read more...]
New Graphene Material Conducts Heat Faster than Silicon
A new graphene material capable of conducting heat 20 times faster than silicon could make the next generation of electronic devices quieter and longer-lasting. The experimental graphene made by U.S. and Chinese researchers has also proven 60 percent more effective at transferring heat than typical graphene — a carbon sheet just one atom thick. Efficient heat removal would … [Read more...]
Organic LED Lighting in European Dimensions
Led by Philips Technologie GmbH in Germany, the OLED100.eu team has been working on OLEDs for the last three years. The aims and objectives of the study were to boost the luminous efficacy, strengthen the lifetime, upscale the light-emitting area, optimize processes to slash production costs, and standardize measurement based on application research. The OLED100.eu team … [Read more...]
Apple to Recreate Ionic Wind Generator Cooling System
The U.S. Patent & Trademark Office has published a patent application that reveals Apple’s intent to reinvent the ionic wind generator. The traditional ionic wind generator design is only effective at cooling limited areas of an electronic device and distributes air throughout the device evenly, without thought to what portions of the device are in use. According to the … [Read more...]
