What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...
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.
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 ...
