Cree MT-G LED.JPGCree is aiming to replace 35-50W halogen MR16 bulbs with its multi-die MT-G LED, writes Steve Bush.

"To date, there are no energy-efficient alternatives for many high-lumen, small form-factor, directional lighting applications. Until now, LED-based MR16 lamps have been a tremendous challenge for the lighting design community in terms of both light output and colour consistency due to their small size and limited capacity for thermal management," said Cree marketing director Paul Thieken. "Cree developed this LED from the ground-up with applications like these in mind."

Wrap around Traffic Signals

By Alun Williams - Electronics Weekly.com on February 7, 2011 12:05 PM | 5 Comments | No TrackBacks
wrap-around-traffic-signals.jpgThanks to Techeblog for highlighting this one - an innovative use of traffic signals involving LEDs. It writes:
Rather than install separate poles for traffic lights, why not put them on existing ones and/or trees? That's the idea behind this clever design by Gisung Han, Hwanju Jeon and Jaemin Lee. Basically, it "comes in two parts: a flexible LED belt that wraps around street furniture and a solar lid which protects it, shades it and powers it."
