Abstract
A light emitting diode can emit light along an axis. An optic can be positioned to direct the emitted light off of the axis. The optic can comprise a base and a projection that rises from the base towards the light emitting diode. The projection can comprise a cavity that is oriented to receive the light emitted by the light emitting diode. The cavity can be slanted relative to the axis of the light emitting diode. A convex surface disposed at the bottom of the cavity can condense, focus, or collimate light. The projection can further comprise sides that totally internally reflect light.
