Abstract: It is well known that inclined sidewall scattering structures can improve the light extraction efficiency (LEE) of micro deep ultraviolet (DUV) light-emitting diodes (LEDs). However, ...
Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...
Cars' headlights have come a long way since charming yet potentially dangerous acetylene headlamps debuted in vintage automobiles. The later halogen headlights are still around, but the world has ...
