There is a blind spot in the center of our vision where the optic nerve comes through to spread over the retina.

Another way to "see" the effect you notice is with the stars. When you look directly at a star it will disappear because it's over the blind spot on the retina.

Or, maybe the LED you noticed is large enough to surround this blind spot and something else is going on.
