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 numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances...

LED lights work very similarly to standard light bulbs except for the fact that LEDs are much smaller and contain no filament. Instead of a filament, an LED creates light using nothing but the movement of electricity along the path of its semiconductor. As the electrons stream across the semiconductor, they create electromagnetic radiation.

How LEDs work. LEDs are simply diodes that are designed to give off light. When a diode is forward-biased so that electrons and holes are zipping back and forth across the junction, they're constantly combining and wiping one another out.

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes , releasing energy in the form of photons .

How an LED Works. What we are interested in with LEDs are the electrons going from a higher orbit to a lower orbit, thus losing energy in the form of a photon of light. When the electrons from the n-type side “fill the holes” in the p-type side, they then lose energy in the form of these light photons.

1. HOW THEY WORK. LEDs create light by electroluminescence in a semiconductor material. Electroluminescence is the phenomenon of a material emitting light when electric current or an electric field is passed through it - this happens when electrons are sent through the material and fill electron holes.

If the LED lights up with the black tip on the longest lead and the red tip on one of the other leads – you have a common cathode RGB LED. Control an RGB LED with the Arduino In this example, we show you how to control the color of an RGB LED using an Arduino.

Connecting LEDs book Connecting LEDs is a practical guide about the understanding of LEDs and how they can light both the interior and exterior. Request the book via this form.
