LED circuit In electronics, an LED circuit or LED driver is an electrical circuit used to power a light emitting diode (LED). The circuit must provide sufficient current supply (either DC or AC, see below) to light the LED at the required brightness, but must limit the current to prevent damaging the LED. Light emitting diode 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.

Light Emitting Diode Structure Georgia State University Electroluminescence in LEDs. When the applied forward voltage on the diode of the LED drives the electrons and holes into the active region between the n type and p type material, the energy can be converted into infrared or visible photons. Polarity learn.sparkfun What is Polarity? In the realm of electronics, polarity indicates whether a circuit component is symmetric or not. A non polarized component a part without polarity can be connected in any direction and still function the way it's supposed to function.
