That means inside every LED bulb are tiny circuit components -- and their soldered contact points -- which are far more vulnerable than the diode itself. The Lighting Research Center of the Rensselaer ...
A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, ...
When picking an LED bulb, it's best to stick with well-known, reliable brands, even if you have to pay a bit more. For smart bulbs, our testers have found some of the best results from Philips, Wiz, ...
Red-emitting dyes offer more explicit images for deep-tissue imaging, but they’ve long been hindered by poor brightness and ...
Abstract: Very strong optical absorption and the poor hole injection efficiency make AlGaN-based deep-ultraviolet light-emitting diodes (DUV LEDs) encounter low external quantum efficiency (EQE) and ...
The protocol outlines standard testing methodologies of things like lumens, runtime, beam distance, and impact and water resistance, meaning that buyers can confidently compare specifications across ...
Abstract: White light-emitting diodes (WLEDs) with high-quality emissions ($\ge 80$ ) are essential for general lighting. However, the color rendering index (CRI) of nanocrystal WLEDs are usually poor ...
HOLED UP AT home when no one else is looking, people indulge in their covert, sometimes embarrassing, self-care routines. One of the newest involves donning a mask that would make the greatest movie ...
