Abstract
A light source includes a light-emitting diode or device (LED) and an optic mounted over the LED. The LED emits a first radiation pattern that is non-rotationally symmetric about a first axis. The optic collects the first radiation pattern and projects a second radiation pattern that is rotational symmetric about a second axis and has a peak intensity that is angled from the second axis.
