Earlier, and perhaps more basic, LED masks usually provide just one primary colour treatment mode, such as red or blue, although this might be attributed to the fact that red light claims to have anti ...

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 ...

Reducing blue light with a new type of LED that won't keep you up all night. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2021 / 04 / 210428140852.htm ...

In a new study published Wednesday, researchers conducted six clinical trials on 216 participants with mild to moderate acne and found that using at-home red and/or blue LED devices led to a 45.3% ...

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 ...

In the study, researchers looked at what happened to fruit flies that were exposed to 12-hour stretches of blue LED light each day. The light damaged both eye cells and brain cells in the flies ...

Teeth bleaching with low concentrations of hydrogen peroxide (6%) and catalyzed by LED blue (450 ± 10 nm) and laser infrared (808 ± 10 nm) light for in-office treatment: Randomized clinical ...

We've had success in converting longer wavelength blue LED light into shorter wavelength UVA. So, our next step was to find compounds that could convert blue LED light to UVB," explains Yanai.

Too much screen time could be taking a toll on your mental health. That’s because your smartphone, tablet, laptop, and TV all give off blue light. So do fluorescent and LED (light-emitting diode ...
