Like someone said earlier.. I was thinking, which can be dangerous.....
I think I understand how LEDs generate light and heat, but would like an explanation from someone who knows for sure.
I am guessing that electron flow somehow causes atoms to jump to higher energy states, and when they atoms decay back, they give off photons. Heat is not part of this process, but mearly generated by electrons passing through the medium and not being absorbed by the light emitting atoms.
I remember hearing about 'holes' that force electron flow, but I dont recall what that was all about.
Now, I may be WAY off, but it sounds good.
