Light Fixture Patents (Class D26/24)
  • Patent number: 10883702
    Abstract: An indirect troffer. Embodiments of the present invention provide a troffer-style fixture that is particularly well-suited for use with solid state light sources, such as LEDs. The troffer comprises a light engine unit that is surrounded on its perimeter by a reflective pan. A back reflector defines a reflective interior surface of the light engine. To facilitate thermal dissipation, a heat sink is disposed proximate to the back reflector. A portion of the heat sink is exposed to the ambient room environment while another portion functions as a mount surface for the light sources that faces the back reflector. One or more light sources disposed along the heat sink mount surface emit light into an interior cavity where it can be mixed and/or shaped prior to emission. In some embodiments, one or more lens plates extend from the heat sink out to the back reflector.

  • Patent number: 10823347
    Abstract: A modular troffer-style fixture particularly well-suited for use with solid state light sources. The fixture comprises a reflector that includes parallel rails running along its length, providing a mount mechanism and structural support. An exposed heat sink is disposed proximate to the reflector. The portion of the heat sink facing the reflector functions as a mount surface for the light sources. The heat sink is hollow through the center in the longitudinal direction. The hollow portion defines a conduit through which electrical conductors can be run to power light emitters. One or more light sources disposed along the heat sink mount surface emit light toward the reflector where it can be mixed and/or shaped before it is emitted from the troffer as useful light. End caps are arranged at both ends of the reflector and heat sink, allowing for the easy connection of multiple units in a serial arrangement.

  • Patent number: 10648643
    Abstract: An indirect troffer. Embodiments of the present invention provide a troffer-style fixture that is particularly well-suited for use with solid state light sources, such as LEDs. The troffer comprises light bars mounted proximate to a back reflector. A back reflector defines a reflective interior surface of the lighting troffer. To facilitate thermal dissipation, the light bar can act as a heat sink. A portion of the heat sink is exposed to the ambient room environment while another portion functions as a mount surface for the light sources that faces the back reflector. One or more light sources disposed along the light bar mount surface emit light into an interior cavity where it can be mixed and/or shaped prior to emission. In some embodiments, one or more lens plates extend from the light bar out to the back reflector.

  • 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.
