Light Fixture Patents (Class D26/24)
  • Patent number: 10544925
    Abstract: Lighting retrofit systems and methods are disclosed that can be used with different light fixtures, but that are particularly adapted for use with retrofitting troffer-style fixtures with LED based light engines. The retrofit systems being assembled without disturbing the lighting or troffer pan or housing (“troffer pan”) for the lighting system being retrofitted. Some of these embodiments can comprise a mounting fixture or frame that can be mounted in an opening in a ceiling grid, and held in place between the grid and the troffer pan edge. The fixture or frame can comprise an opening for a light engine, with the engine being quickly and easily connected to electrical power in the troffer pan and then mountable within the frame opening. These embodiments can allow for the quick and easy construction of the retrofit system without the need for adhesives and fasteners such brackets and screws.

  • Patent number: 10514139
    Abstract: A solid state lighting fixture with an integrated driver circuit. A housing has a base end and an open end through which light is emitted from the fixture. The reflective interior surface of the fixture and the base define an optical chamber. At least one, and often multiple, light sources are mounted at the fixture base along with the circuitry necessary to drive and/or control the light sources. The drive circuit and the light sources are both located in the optical chamber. A reflective cone fits within the optical chamber such that it covers most of the drive circuit and other components at the base of fixture that might absorb light. The reflective cone is shaped to define a hole that is aligned with the light sources so that light may be emitted through the hole toward the open end of the fixture.

  • Patent number: 10309627
    Abstract: Retrofit systems and methods are disclosed for lighting installations, and in particular, to retrofit systems and methods used to retrofit troffer-style lighting installations with LED light sources. Retrofit systems can be used with different light fixtures, but those described are particularly adapted for use with troffer-style fixtures. These retrofit systems can provide the same amount of light as traditional light fixtures already do, for example 1600-4000 lumens or more. The retrofit systems can be used with many different light sources but are particularly well-suited for use with solid state light sources or light engines, such as those utilizing LEDs. Some embodiments of the present invention comprise a mechanical mounting system for installing an LED light engine within an existing lighting system housing or pan, such as a troffer pan, without penetrating the ceiling plenum.

  • Patent number: 10228111
    Abstract: A direct troffer-style fixture for solid state light sources and pan structures for use in these fixtures. The fixture comprises a door frame assembly that is attached to the pan. The pan housing is defined by a base and two angled side walls. End caps are attached to the side walls. End reflectors extend at an angle away from the end caps and attach to the base. The end caps, the end reflectors, and the base define compartments at both ends of the housing in which components can be housed. A light board is attached to the base using alignment holes in the base and cutout portions of the end reflectors. The multifunctional end reflectors retain elements within the compartments, provide added structural stability to the pan, aid in aligning a light board, and they reflect light that impinges on them toward the open end of the fixture.

  • Patent number: 10012354
    Abstract: A direct troffer-style fixture for solid state light sources for use in these fixtures. Embodiments of the present invention provide a direct troffer-style fixture that is particularly well-suited for retrofit structures. The fixture comprises a retrofit troffer assembly that is removably attached within a T grid or pan structure. The retrofit fixture can be installed in two pieces: a first including a lens structure, a back reflector and 2 end reflectors; and the second component including a second portion of the back reflector. An interior space created by the lens structure houses light emitters and in some embodiments, a light engine and/or additional electronics. One or both of the end reflectors may be movable, slidable and/or rotatable, to accommodate installation. The back reflector covers most of the interior surfaces of the troffer fixture to direct more light out of the fixture.

  • Patent number: 9874322
    Abstract: Troffer-style lighting fixtures are disclosed having troffer housing with reflective regions, and respective light emitting diode (LED) arrays mounted in the reflective regions. The LED arrays are arranged to emit out of said troffer housing to illuminate a room below. The LED arrays can be driven by an elevated drive signal to produce a high luminous flux. The light fixtures according to the present invention can have lenses and diffusers over the arrays arranged to mix and disperse light from the light source to reduce hot spots and the appearance of individual LED colors. A plurality of first diffusers is included, each over a respective LED array. A second diffuser is included over the first diffusers, with the LED light passing through the diffusers prior to emitting from the lighting fixture. The diffusers can have shapes, surfaces or materials to disperse and/or mix the LED light as it emits.

  • Patent number: 9822951
    Abstract: Light fixtures having light bar elements therein. In order to mimic the size and appearance of fluorescent bulbs in existing troffer-style and surface-mount fixtures, LEDs are may be arranged on light bars with integrated lenses to both diffuse the light and shape the output beam. One or more LEDs can be mounted, sometimes in clusters, along the length of a base of the light bar which can then be inserted into a fixture. An elongated lens is mounted to the base over the LEDs so that light emitted from the LEDs interacts with the lens before it escapes the fixture. These elongated lenses may be extruded from a diffusive material, for example, and can be shaped in various ways. For example, the lenses may be shaped to disperse more light to the sides, i.e., in a direction away from a normal axis that is perpendicular to the base.

  • Patent number: 9777897
    Abstract: Lighting fixtures are described utilizing a plurality of light sources, or light engines, which are mounted together in a modular fashion in the light fixture opening. In some embodiments, the plurality of light sources can comprise lighting panels that together form the overall fixture light source. The present invention is particularly applicable to troffer-style lighting fixtures that can be arranged with a plurality of lighting panels arranged in the troffer opening to illuminate the space below the troffer. Embodiments of the present invention can also utilize solid state light sources for the lighting panels, with some embodiments utilizing light emitting diodes (LEDs).
