A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an ...
Researchers at the Hong Kong University of Science and Technology (HKUST) School of Engineering have cracked a major challenge in display technology by inventing the world's brightest and most energy ...

Are today’s LED headlights too bright for safe driving?
Modern LED headlights help drivers avoid danger by lighting up more of the road but glare from blazing bright LED lights can blind oncoming traffic.
Microscopic light-emitting diodes (LEDs) have applications ranging from augmented-reality displays to large-screen products, but their brightness typically decreases as their size is reduced. A ...
LEDs work by converting electrical energy into photons in a layer made of a semiconductor. Research into new semiconductor materials is key not only to further improving the energy efficiency of these ...
Combine that with the fact that in the dark the rods in our eyes are more sensitive to blue light and that since there are more rods towards the edge of the retina, our peripheral vision picks up the ...
LEDs provide excellent color rendering and uniformity of light, and thereby achieve a high light quality for most lighting applications. LEDs also give designers a whole new palette of color, and, by ...
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 ...
