The idea's setup is this: There is a LED with solar panel and a battery, from one of the sun-charged nightlights, and an optic fiber (the "mirror") that routes the light from the LED onto it's own solar panel. The effect is that the light dims about half way down. Question: What exactly happens in there? Specifically, -Does the LED gets continuously dimmer (and why)? -Or, does it start to blink on and off very fast thus appearing dimmed (and why, what kind of wave would it be)?
