The Light emitting diode is a two-lead semiconductor light source. In 1962, Nick Holonyak has come up with an idea of light emitting diode, and he was working for the general electric company. The LED is a special type of diode and they have similar electrical characteristics of a PN junction diode Light Emitting Diode (LED) Definition: The LED is a PN-junction diode which emits light when an electric current passes through it in the forward direction. In the LED, the recombination of charge carrier takes place. The electron from the N-side and the hole from the P-side are combined and gives the energy in the form of heat and light Light Emitting Diode (LED) A light emitting diode (LED) is a forward biased PN junction diode, which emits visible light when energized. When a junction diode is forward biased, electrons from N-side and holes from P-side move towards the depletion region and recombination takes place

The light emitting diode emits light when it is forward biased. When a voltage is applied across the junction to make it forward biased, current flows as in the case of any PN junction. Holes from the p-type region and electrons from the n-type region enter the junction and recombine like a normal diode to enable the current to flow Define light-emitting diode. light-emitting diode synonyms, light-emitting diode pronunciation, light-emitting diode translation, English dictionary definition of light-emitting diode. n. LED. American Heritage® Dictionary of the English Language, Fifth Edition Light Emitting Diode Structure LEDs are p-n junction devices constructed of gallium arsenide (GaAs), gallium arsenide phosphide (GaAsP), or gallium phosphide (GaP). Silicon and germanium are not suitable because those junctions produce heat and no appreciable IR or visible light

In fact, LED stands for Light Emitting Diode. (It does what it says on the tin!) And this is reflected in the similarity between the diode and LED schematic symbols: In short, LEDs are like tiny lightbulbs. However, LEDs require a lot less power to light up by comparison Light-emitting diodes and semiconductor lasers typically have gratings or etched ridges in which light is reflected or transmitted many times at the interface between different materials. Figure 10.20 illustrates the amplitudes of light at the interface of two semiconductors with indices of refraction, n 1 and n 2
