How LEDs Work Answered
Right, so i know that LEDs work when a electron meets a hole and drops into a lower energy state. This releases energy in the form of a photon.
After a few experiments for college i can show that as current increases light output increases i'm assuming this is because more current = more electrons = more energy released = more photons = more light output. Correct?
Another of the experiments i did was to investigate the heat around the led and the light out. It turns out that as the heat goes up, lumen output goes down.
Now the question, why (in a physical sense) does this happen?
Do the holes become less? why?
