The transition from light bulbs to LEDs has drastically cut the amount of electricity we use for lighting. Most of the electricity consumed by incandescent bulbs was, after all, dissipated as heat. We may now be on the verge ...
General Electric has reached an agreement to sell its overseas lighting operations in Europe, the Middle East, Africa and Turkey, the conglomerate said Thursday.
By shining a laser along the inside shell of an incandescent light bulb, physicists have performed the first experimental demonstration of an accelerating light beam in curved space. Rather than moving along a geodesic trajectory ...
Light-emitting diodes—or LEDs, as they are commonly known—have been slowly replacing incandescent light bulbs in applications ranging from car taillights to indicators on electronics since their invention in the 1960s.
Physicists at Aalto University have discovered a microscopic mechanism that will allow gallium nitride semiconductors to be used in electronic devices that distribute large amounts of electric power.
Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light.
Electrical engineers at Duke University have created the world's first electromagnetic metamaterial made without any metal. The device's ability to absorb electromagnetic energy without heating up has direct applications ...
Anyone who has stood in confusion in the light-bulb aisle (and that's most of us) knows that technology and the push to save energy are continuing to flip the script on home lighting options.
The intensity of artificial lighting has been shown to have a range of effects on our mood and our ability to concentrate. New research explores the color of lighting and its effect on our cognitive performance. The study, ...
Traditional light bulbs, thought to be well on their way to oblivion, may receive a reprieve thanks to a technological breakthrough.
