    Abstract: An optical assembly and a luminaire with extreme cutoff beam control optics. The optical assembly includes a base, at least one lens, at least one light emitting diode (LED) positioned to emit light into the lens, and a curved reflector disposed adjacent to the LED. The reflector can be characterized by a first angle between a plane of the base and a first line joining a distal end of the lens furthest laterally from a first end of the reflector and a second end of the reflector located over the lens, and a second angle between the plane of the base and a second line joining a point on the lens located at the optical axis of the LED and the second end of the reflector. The first angle can be between 60° and 90°, and the second angle can be between 70° and 130°.

    Abstract: An optic having a first optic portion located on a first side of the optic and a second optic portion formed integrally with the first optic portion and located on a second side of the optic. A first cavity is defined by a first cavity inner surface in the first optic portion, the first optic portion being configured to refract light rays emitted by at least one light source. The second optic portion includes at least one total internal reflection surface and a second cavity defined at least partially by a second cavity rear surface that extends at an angle between 20° and 60°, inclusive, relative to an axis defining the height the of the optic. The second cavity rear surface is configured to refract other light rays toward the at least one total internal reflection surface, and the at least one internal reflection surface is configured to reflect the light rays toward the first side of the optic.

    Abstract: An optic for aisle lighting includes a portion of an optical material defined by a length and a cross-sectional profile. The cross-sectional profile is characterized by a cavity within the optical material, two upwardly-facing surfaces of the optical material on opposite sides of the cavity from one another, and downwardly-facing surfaces of the optical material. The cavity is bounded by an upward facing aperture, and at least three faces of the optical material that meet at interior angles. Light received through the upward facing aperture is separated at the interior angles, and refracted by the faces of the optical material, into separate light beams equal in number to the faces. The two upwardly-facing surfaces internally reflect the separate light beams downwardly. The downwardly-facing surfaces intercept respective portions of the separate light beams, and refract the portions as they exit the optic.

    Abstract: An LED assembly that includes optics and optical arrangements for light emitting diodes (LEDs). In some embodiments, a reflector is provided within a void between the lens and the LED. This reflector can reflect light emitted by the LED in a non-preferred direction back toward the preferred direction. In other embodiments, an optical element is formed or otherwise provided in the lens cavity and shaped so that, when the lens is positioned above the LED, the refractor bends the emitted light in a preferred direction. In some embodiments, both a reflector and optical element are provided in the LED assembly to control the directionality of the emitted light. Such embodiments of the invention can be used to increase the efficiency of an LED by ensuring that generated light is being directed to the target area of choice.
