    Abstract: Disclosed and described herein is a sharp cutoff LED lighting luminaire and methods of use thereof. Further disclosed is a modification thereof which allows baseballs or detritus trapped by the luminaire to fall to the ground. In the state of the art often designers will use the same type of LED lighting fixtures at the top of the pole as for low-mounted uplighting; specifically, taking an additional fixture similarly configured, inverting the orientation (i.e., so to project upward instead of downward), and mounting it relatively low on the pole. The envisioned sharp cutoff LED lighting fixture is better suited for low-mounted uplighting insomuch that it reduces back light, haze, internal glow, and perceived glare as compared to current LED lighting fixtures typically used for the same purpose.

    Abstract: A lighting system can include a lightguide having an edge and two major surfaces. The lightguide can be mounted in a frame so that one of the major surfaces faces towards an area to be illuminated, while the other major surface faces away from the area. LEDs can couple light into the lightguide edge, with the coupled light emitting from both major surfaces. Light emitted from the major surface that faces away from the area to be illuminated can be reflected back into the lightguide by a reflective surface. The reflective surface can be separated from the lightguide by an air gap. The air gap can promote internal reflection at the major surface facing away from the area to be illuminated, thereby enhancing homogeneity and output of light towards the area to be illuminated. The frame can include integral wireways, reflector retention clips, and grounding circuitry.

  • Patent number: 9581318
    Abstract: A recessed lighting optical holder for a recessed lighting fixture, comprises a retainer 100 having a generally annular shape, including a resilient snap projection 105 formed on an inner circumference and resilient beam 130 supported at both ends on an outer circumference. The beam slides into engagement with a heat sink extension 122 on a bottom portion of a circular heat sink 110, when a top surface of the retainer is positioned against a bottom portion of the heat sink and the retainer is rotated with respect to the heat sink, to lock the retainer to the heat sink. An optic 120 has a generally conical shape, with a bottom portion surrounded by circular lip 125 that snaps into holding engagement with the snap of the retainer, to positively retain the optic. The holder is relatively simple to manufacture and is conveniently accessible for installation and occasional maintenance or replacement.

  • Patent number: 9366410
    Abstract: An elongated lens profile having reverse total internal reflection (TIR) features that improve light extraction when the lens is used in conjunction with a plurality of light emitters. Solid state light emitters, such as LEDs, are arranged proximate to the elongated lens along a longitudinal axis of the lens body. The emitters, which may be grouped in clusters, emit toward a receiving surface of the lens. The receiving surface includes a plurality of reverse TIR features, also disposed along the longitudinal axis. These features may be defined by a series of recessed areas spaced along the longitudinal axis to correspond with the light emitters which can protrude into the negative space created by the recessed features. The recessed features may have more than one shape. The reverse TIR features improve light output uniformity, reducing hot spots along the lens, and improve output efficiency.
