LED FULL FORM
Full Form of LED : Full Form of LED is Light Emitting Diode.
What is the full form of LED?
No:1. The full form of LED is Light Emitting Diode.
No:2. The LED is a PN-junction diode that produces light as it passes via an electric current in the forward path.
No:3. Recombining the charge carrier occurs in the LED.
No:4. The N-side electron and the P-side hole are mixed and provide the energy in the form of light and heat.
No:5. The LED is produced from the colourless semiconductor substance, and the light is radiated via the diode junction.
No:6. Depending on the semiconductor material used and the doping quantity, a colored light will be emitted at a specified spectral wavelength when LEDs is biased forward.
No:7. The symbol of the LED is similar to the symbol of the p-n junction diode. The distinction between those two symbols is that the two arrows indicate the diode emitting the light.
