How Light Emitting Diodes Work
Light
emitting diodes, commonly called LEDs, are real unsung heroes in the electronics
world. They do dozens of different jobs and are found in all kinds of devices.
Among other things, they form the numbers on digital clocks, transmit
information from remote controls, light up watches and tell you when your
appliances are turned on. Collected together, they can form images on a jumbo
television screen or illuminate a traffic light.
Basically, LEDs are just tiny light
bulbs that fit easily into an electrical circuit. But unlike ordinary
incandescent bulbs, they don‘t have a filament that will burn out, and they
don‘t get especially hot. They are illuminated solely by the movement of
electrons in a semiconductor material, and they last just as long as a standard
transistor.
In this article,
we’ll examine the simple principles behind ubiquitous blinkers, illuminating
some cool principles of electricity and light in the
process.
