Abstract
An optic can receive light from a dome of a light emitting diode and output light that, when cast upon a nearby flat surface, forms a strip of illumination. The optic can comprise a cavity that receives the light from the dome and an outer surface that emits the received light. An edge of the cavity can extend peripherally around the cavity in an oblong geometry. An edge of the outer surface can extend peripherally around the outer surface in an oblong geometry that is rotated ninety degrees relative to the oblong geometry of the cavity. A sidewall of the outer surface can comprise a region that is concave in nature or sags.
