    Abstract: A tubular light comprises an elongate light source (10) and a tubular housing (18) around the light source. An optical beam shaping arrangement (20) is provided within the housing. It has an effective focal distance, in the plane perpendicular to the length axis, which varies in dependence on the angular position around the optical beam shaping arrangement. The effective focal distance is longer for light in a light output optical axis direction than for light output laterally to the sides of the light output optical axis. This means the beam shaping, e.g. collimation, is greater at the edges of the light output beam than in the middle, so there is light mixing within the output beam.

  • Patent number: 10466403
    Abstract: An apparatus and method for assembling a display device to which is coupled a light guide that has smooth surfaces for light-transmission and at least one surface that is for light scattering and internal reflection. The method includes depositing a reflective coating on that surface, and installing the display device with coupled light guide in an interior of a meter housing or casing. A portion of the casing interior is filled with a component, such as epoxy, for sealing the case interior to protect the display device and light guide against water and dust penetration. All surfaces of the light guide are protected from direct contact with the epoxy. This approach greatly simplifies the assembly process and yields a robust display that also prevents light leakage from the light guide.

  • Patent number: 10393341
    Abstract: A tri-lobe optic for a linear light source, and related light rails, retrofit kits and light fixtures, are disclosed. The linear light source defines a light emitting region along an axis. The tri-lobe optic includes an optical material having a constant cross-sectional profile along a direction of the axis from a first axial end to a second axial end. The cross-sectional profile includes a first azimuthal side relative to the axis and concave and convex curves relative to the axis. The curves are a first concave curve coupled with the first azimuthal side, a first convex curve, a second concave curve, a second convex curve and a third concave curve. Each of the concave curves defines a lobe of the optical material along the direction of the axis. The cross-sectional profile further includes a second azimuthal side relative to the axis, coupled with the third concave curve.

  • Patent number: 10344948
    Abstract: There is a category of situations which may have previously been considered direct replacement but in fact takes on many elements of a true retrofit; namely, replacing existing LED lighting systems (which they themselves were retrofits) with different LED lighting systems that (i) overcome a deficiency or inadequacy of the existing LED lighting system retrofit, (ii) adds a functionality to the existing LED lighting system retrofit, or (iii) reestablishes functionality that would otherwise be lost with the existing LED lighting system retrofit. Discussed herein are means to provide improved glare control, horizontal beam containment, playability and control functionality for interfacing with third party controls in these so-called retrofit-of-a-retrofit, or “upgrade” situations.

  • Patent number: 10288240
    Abstract: A system and method of converting a light fixture from a conventional light fixture to an LED light fixture. Originally, the light fixture has a troffer, a ballast unit, and bulb receptacles. The conversion is accomplished by mounting a panel over the face of the troffer that obscures the ballast unit and bulb receptacles. LED light strips are mounted to the panel. Likewise, an LED power supply is mounted to the panel. The panel is attached to the troffer with a hinge connection. In this manner, the panel can be rotated away from the troffer for easy access.

  • Patent number: 10267491
    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.

  • Patent number: 10180215
    Abstract: A luminaire system is provided that has directional light projection optics combined with a light distribution modifier to produce a non-uniform angular light intensity distribution from a single or array of light sources. The luminaire system provides for light intensity distribution with directional asymmetry meeting the specifications and requirements of aviation obstruction lights. The light distribution modifier component or subassembly redirects, scatters, refracts, diffracts and/or blocks part of the projection light in the distribution of the primary optics that would otherwise produce ground scatter. Unlike peripheral light shields at the marginal limits of the light distribution from the luminaire light system, the light distribution modifier is located near to the optical axis of the projection optics system.
