Open Image…Save ImageOpen Image (using #TmpD/ia)… The National Institute of Standards and Technology (NIST) has a new design for light-emitting diodes that achieves a dramatic increase in brightness as well as the ability to create laser light. These characteristics could make it valuable in a range of applications. The device shows an increase in brightness of 100 to 1,000 times […]

Researchers at Aalto University and VTT Technical Research Center of Finland have succeeded in developing a method which helps to improve the relative uncertainty in measuring the luminous efficacy of LEDs. The improvement from the approximate five percent of today to one percent in the future may save billions in lighting costs in the future. […]

Two researchers at Sandia National Lab suggest their research shows, historically, that improvements in lighting from candles to gas lamps to electric bulbs have led to increased light consumption rather than lower overall energy use. Back in 2010 Jeff Tsao at Sandia and Harry Saunders of The Breakthrough Institute in Oakland, Calif., authored an article […]
