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. The
LED is made of semiconductor material which is colourless, and the
light is radiated through the junction of the diode.
Please note that an
LED must have a
diode junction to emit light, thus it must be a
diode!!
So we all end up with a smile
If you don't have any "diode junction" how can you have any "LED light", how can you have any "LED light" if you don't have any "diode junction"!!
Since after all, we are all just another Brick in the Wall!!
Best,
Research is like a treasure hunt, you don't know where to look or what you'll find!
