Thomas Edison may have invented the lightbulb, but he never received the Nobel Prize for it. Isamu Akasaki and Hiroshi Amano at the University of Nagoya, and Shuji Nakamura working at Nichia Chemicals ...

In many cities today, streets are lit by white lights, screens show vivid colors, and buildings glow with precise patterns of illumination, all depending on a small but important invention from the ...

Three researchers helped revolutionize lighting with vastly better energy efficiency and brightness. The light-emitting diodes also are used in data storage, TVs and smartphones. Stephen Shankland ...

OK, it's not really a black light. It's better to call it what it is: ultraviolet light. Let's start with a quick overview of light. Of course, light is an electromagnetic wave (oscillating electric ...

Light-emitting diodes (LEDs) are so ubiquitous that it's easy to forget just how much society relies on these underappreciated technological wonders. Yet, the history of the LED goes back further than ...

The blue light in LED lighting that is increasingly used in our homes can damage the eye’s retina while disturbing our biological and sleep rhythms, a French health authority warned in a new report.
