How LEDs work by VirtualBrain
. Source. 2021. Good 3d schematics clearly explaining part of the LED electronic package.How are LED Chips and LED Encapsulation is made by Future Linear
. Source. Starts from some level of cut square chips. Still in round wafer form.www.reddit.com/r/Optics/comments/18f6bdt/comment/kcsiook/ mentions:
LEDs are broadband by nature, since the spontaneous emission broadly speaking reflects the overlap of the Fermi distribution and the density of states
Direct and indirect band gaps is an important part of why diodes don't emit light apparently.

Apparently fundamentally LEDs in principle work as photodetectors, but
