Researchers at the Niels Bohr Institute have discovered a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. Using lasers, researchers cooled membrane fluctuations to minus 269 … [Read more...]

New Liquid-Cooled LED as Bright as 100W Bulb
SWITCH Lighting’s™ SWITCH bulbs have a ring of metal prongs, each with a computer chip on it to emit light, which is immersed in liquid that fills each bulb. The liquid cools the chips while acting as a lens to magnify light. SWITCH bulbs use 80 percent less electricity than incandescent bulbs and last for about 25,000 hours no matter often you switch them on or off. Learn … [Read more...]
Lighting-Class LEDs Deliver Twice the Lumens-Per-Dollar
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...]
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...]
