The world has been shifting away from wasteful incandescent and harmful fluorescent lights and increasingly adopting light-emitting diode (LED) technology, which promises to reduce carbon emissions.

The LED lighting industry lost one of its founding fathers on September 18 th of this year with the passing of Nick Holonyak, Jr, known as the “Father of the light-emitting diode”. His invention of a ...

Designers of early indoor LED light bulbs faced numerous technical hurdles, including AC-to-DC conversion, thermal heat-sinking, constraints imposed by current bulb sizes, electrical transients, and ...

I don’t know about you, but although I like reading about electronics in a theoretical sort of way, there’s nothing I enjoy more than the hands-on building of something and then watching that thing ...
