Principle: The electrons injected into the p- region make a direct downward transition from the conduction band into valence band and they recombine with holes and emit photons of energy E g.. We know that the forbidden gap energy is given by Working of PN Junction Diode Background: In the early 1990s, the biological significance of light-emitting diodes was realized. There are two major kinds of light emitting diodes: LED and OLED.The LED is different than EL lamp in that it uses a small semiconductor crystal with reflectors and other parts to make the light brighter and focused into a single point. A laser diode emits radiation of a single wavelength or sometimes a narrow band of closely spaced wavelength. The construction of a Light Emitting Diode is very different from that of a normal signal diode. An organic light-emitting diode (OLED) is a light emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. Adoption of Light-Emitting Diodes in Common Lighting Applications Prepared for the U.S. Department of Energy Solid-State Lighting Program July 2017 Prepared by Navigant. Light-emitting diodes (LEDs) are promising lighting sources for general lighting applications with the promise of being more than ten times as efficient as incandescent lighting. •Light diverges significantly •LASER •Light is essentially single wavelength (highly monochromatic) A Laser Diode is a semiconductor device similar to a light-emitting diode (LED). •Light Emitting Diode •Light is mostly monochromatic (narrow energy spread comparable to the distribution of electrons/hole populations in the band edges) •Light is from spontaneous emission (random events in time and thus phase). PN Junction diode is a device made of two semiconductor material joined together with the required amount of impurity. The symbol for an LED is shown in Figure. 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. It uses p-n junction to emit coherent light in which all the waves are at the same frequency and phase.

When current passes through the LED, the electrons recombine with holes emitting light in the process. PN junction diode is a diode which can be used as a rectifier, logic gate, voltage stabiliser, switching device, voltage dependent capacitor and in optoelectronics as a photodiode, light-emitting diode (LED), laser diode, photo detector, or solar cell in electronics.
