Abstract: A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards a street is beneficial. The source can be coupled to an optic that comprises a cavity. At least a portion of the cavity can have an outline that is egg-shaped in cross section. A backside of the cavity (or a backside portion of the optic) can have an irregular shape for receiving the light emitting diode, for example to form a receptacle shaped to fit a circuit.

Abstract: A lighting system includes an optic that has at least two reflective surfaces that are oriented such that they face each other. Further, the lighting system includes a plurality of light emitting diodes that are disposed adjacent one end of the optic. Furthermore, the lighting system includes a lightguide that is disposed adjacent an opposite end of the optic such that an edge of the lightguide is retained within and disposed between the at least two reflective surfaces of the optic. The at least two reflective surfaces of the optic reflect and guide light emitted by the plurality of light emitting diodes to the edge of the lightguide. The light then couples into the lightguide through the edge and is guided towards an opposing edge of the light guide. The light exits the lightguide through the opposing edge and/or major surfaces of the lightguide.

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.
