Blue LEDs and a revolution in light

Morning in Lindau: great scenery and wonderful talks

Morning in Lindau: great scenery and wonderful talks.

By Hamish Johnston at the Lindau Nobel Laureate Meeting in Germany

It has been a great morning of physics talks this morning here at the 66th Lindau Nobel Laureate Meeting. Hiroshi Amano, who shared the 2014 Nobel Prize for Physics for the development of the blue LED, spoke first about the practical aspects of his creation.

Electronic displays and low-energy lighting are two obvious applications for blue LEDs. Amano pointed out that LED lighting uses 1/8 the energy of incandescent bulbs and 1/2 that of fluorescent lights. But perhaps more importantly, he says that this low-energy operation means that light can be introduced to remote and poor parts of the world. This has the potential to boost education because it enables children in areas with no mains electricity to read and study at night.

Bright lights, big city: a lighting revolution comes to New York

Bright spark: Giana Phelan of OLEDWorks shows-off some of the company’s wares.

By Robert P Crease in New York

“One well-lit place” is the best way to describe the exhibition hall at Javits Center in New York when it opened on Tuesday morning. I fully expected to be bedazzled at every turn because the venue is hosting LIGHTFAIR, the world’s largest lighting technology trade fair, and so the hall is packed with more than 600 booths designed to highlight, so to speak, the world’s lighting revolution.
