This is probably a stupid question but here it is:
I am just learning concepts of LEDs. To me, it seems that there is no difference between LED and normal diodes. In normal diodes in forward bias, electrons come from n type and recombine in p type right? In this process photon should be emitted. Why we don't see that photon in normal diodes?
It says here in my textbook that same happen with LEDs. But what to you know normal diodes don't emit light and LEDs do :D
