Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity. They will cost about $3.00 and last up to 60 years.Read More

Siemens researchers are able to wirelessly transfer data at 500 Mbps using white LED light

In collaboration with the Heinrich Hertz Institute in Berlin, Siemens has achieved a data transfer rate of up to 500 megabits per second (Mbit/s), significantly bettering Siemens' previous record of 200 Mbit/s. Wireless data transport by means of light paves the way for new applications in the home as well as in industry and transportation. The researchers used an Ostar LED, one of the brightest LEDs on the market.Read More

Fusing his background in engineering and innovative design, Moritz Waldemeyer's work with LEDs and lasers see him as the first port of call for designers and artists looking for concepts with a digital twist. When Wallpaper approached Waldemeyer to design a ‘Home Disco’, he responded with typical flair, producing this magical, awe-inspiring electro coffee-table.Read More

The Siemens Superstar consists of 9,000 light-emitting diodes

Siemens has powered up its Siemens Superstar, a revolving LED landmark that will stay lit from now until the day of the Epiphany (January 6th, 2010), with permission from the city of Munich.Read More

Cities discover LED bulbs don't burn hot enough to melt the snow covering them

Cities around the country that have installed energy-efficient traffic lights are discovering a hazardous downside: The bulbs don't burn hot enough to melt snow and can become crusted over in a storm — a problem blamed for dozens of accidents and at least one death.Read More

Hide your pets - this robotic mousetrap was designed to detect and exterminate everything in sight

"Many people have been trying to develop a 'better mousetrap' for years, so we decided to build one in the literal sense," says its developer Jake Easton.Read More

Tiny semiconductor crystals could produce better colors for lighting and computer displays

The next big thing in solid-state lighting may be exceedingly tiny—the quantum dot. Researchers from around the world gathered at the Materials Research Society fall meeting in Boston last week to discuss the progress they're making in using quantum dots to enhance the color and efficiency of light-emitting diodes (LEDs).Read More
