Your getting caught up on the name, an LED will only work in one direction, hence the word diode in the name. However, they will not work to stop “back” voltage/reverse voltage, most of the LEDs today the reverse voltage is half or less of the forward voltage. The standard diode has anywhere from equal to up to normally four times the back voltage, and I say normally because I find one with, if I remember right it was 10 to 12 times the back voltage, but I am not spending $182 for a diode. Remember the resistor only limits current not voltage, so the EE’s tell me, I never understood that completely.

So why do you need another diode in the circuit being discussed?
