Abstract: An asymmetric total internal reflector (TIR) lens and a luminaire including a plurality of asymmetric TIR lenses designed to provide increased control on spill light and produce asymmetric distribution within each TIR lens and that does not require a secondary optic arranged at an exit plane of the TIR lens. The TIR lenses disclosed herein utilize a refractive member having a plurality of portions, each portion includes a middle longitudinal edge, a middle lateral edge; and a middle corner formed between the middle longitudinal edge and the middle lateral edge. The TIR lens also includes a collimator arranged about the refractive member that includes an inner surface configured to receive electromagnetic radiation from the refractive member and reflect or refract it through an exit plane of the TIR lens.

Abstract: An optical device for a light fixture can include a quasi-semi-cylindrical outer perimeter that includes a substantially planar bottom surface, a top surface located adjacent to the bottom surface, where the top surface has a curvature, and a pair of side surfaces located adjacent to the bottom surface and the top surface, where the pair of side surfaces are located opposite each other. The optical device can also include a body bounded by the outer perimeter. The optical device can further include an inner optical feature disposed in the body at the bottom surface, where the inner optical feature forms a cavity bounded by multiple segments, wherein each two adjacent segments form an angle relative to each other. The cavity can be configured to receive a light source of the light fixture.

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.

Abstract: A downlight fixture includes a housing reflector member having a top edge that defines a first aperture, a bottom edge that defines a second aperture, and a body that extends from the top edge to the bottom edge. Further, the downlight fixture includes a top reflector panel coupled to the housing reflector member such that it covers the first aperture. Furthermore, the downlight fixture includes a lens that is coupled to the housing reflector member such that it covers the second aperture. An inner surface of the body and a surface of the top reflector member facing the lens are reflective. Additionally, the downlight fixture includes a plurality of light sources disposed on the top reflector member adjacent a perimeter of the top reflector panel such that the plurality of light sources are outside a perimeter of the lens and facing the inner surface of the housing reflector member's body.
