Locked and Loaded with Lumens, a Sophisticated LED Bi-Pin GU24 LED Lamp Replaces the 13W CFL; lighting designs come alive with over 700 lumens of warm white light in this clean replacement bulb. Chip on Board (COB) LED technology offers high heat conductivity and low thermal resistance for improved heat management; the aluminum housing is both attractive and functional, presenting a threaded body that is both compatible with standard GU24 locking rings and also acts as the bulb heat sink,...

Peter Suciu for redOrbit.com – Your Universe Online Until the advent of the electric light, cities were not exactly welcoming places after nightfall. Today, street lights make it easier to see the way after the sun goes down, but this is one of the major contributors to light pollution that washes out the night sky. It has gotten so bad the International Dark-Sky Association held weeklong festivities earlier this month, which was designed to promote ways to help put a dent in light...

University of Illinois When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy. The self-assembled wires have a core of one composition and an outer layer of another, a desired trait for many advanced electronics applications. Led by professor Xiuling Li, in collaboration with professors Eric Pop and Joseph Lyding, all professors of electrical and...

University of Cincinnati research describes discovery of a new structure that is a fundamental game changer in the physics of semiconductor nanowires. There’s big news in the world of tiny things. New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts with...

Lee Rannals for redOrbit.com - Your Universe Online Researchers have identified what causes light emitting diodes (LEDs) to be less efficient at high drive currents, opening up the door for the energy efficient lighting alternative to be better implemented. Previously, scientists had only theorized about the cause behind LED "droop," which refers to a mysterious drop in the amount of light produced when a higher current is applied to the lights. This phenomenon has helped hold LED...
