I have to admit, this week's What's Up With That? query truly had me stumped. But it turns out blue streetlights are explainable, if not ideal.

In this work, for the first time, a sub-250 nm light-emitting diode (LED) is investigated as a light source for optical detection in chemical analysis. A 235 nm deep ultraviolet-light-emitting diode ...

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

Defect inspection is an important part of the light-emitting diode (LED) production process. In the production environment, most of the defects to be inspected are small targets below 32×32 pixels, ...

MALAPPURAM: Researchers at the University of Calicut have made a significant breakthrough in next-generation light-emitting diode (LED) technology by engineering an innovative LED device using ...
