The negative terminal (Anvil) has a cavity where the semiconductor die is placed. This cavity is shaped so as to reflect the produced light into upward direction.
That made my concept clear. Thank you Engineersgarage! How ever, I would like to know more about the last point mentioned in this article."The material used and doping levels are set so as to produce photons with wavelength in the range of desired color of light in the visible spectrum". What is this doping level? How is it selected?

The doping level is adjusted my the amount of doping material used for making the semiconductor.. And on the basis of the amount of doping material the amount of photons is calculated.. Which let us know the colour of LED.. I think this may clear the doubt...

amazing. turns out how little
amazing. turns out how little we know about the most commonly used electronic component.
gr8 work EngineersGarage!

Really good work. I wonder
Really good work. I wonder how you took that cavity out of the glass casing without any damage.
nice work dhawal likes it
