Abstract: An optic configured to create an asymmetric pattern of illumination includes a cavity defined by a sidewall. The cavity is oriented to receive light emitted by a light source that is disposed adjacent a light source receiving end of the cavity. Further, the optic includes a totally internally reflective surface that extends circumferentially about the sidewall and is tapered, so as to reflect emitted light that passes through the sidewall of the cavity and into a body of the optic. The totally internally reflective surface can have a form that is different on opposing sides of the cavity. Furthermore, the optic includes a convex surface that is disposed at a light emitting end of the sidewall to condense, focus, or collimate emitted light from the light source.
