  • Patent number: 11441747
    Abstract: The present invention relates to different embodiments of lighting fixtures, such as high bay lighting fixtures, comprising one or more improved features. Some of these features include the direct mounting of emitters on a heat sink and/or the use of a template-like board for providing an electrical connection between emitters. These features can improve heat dissipation from the emitters and simplify fabrication. In other embodiments, expensive lens optics of prior art SSL fixtures can be replaced with a flat lens and reflector in order to produce a fixture having a satisfactory spacing criterion.

  • Patent number: 11417979
    Abstract: A shielded electrical connector assembly includes an electromagnetic shield integrally formed from a single sheet of conductive material. The shield has a main wall and four side walls surrounding the main wall. The shield defines an opening opposite the main wall having an opening perimeter that is greater than or equal to a main wall perimeter. One of the four side walls defines at least one side wall opening that is configured to receive a shielded wire cable. A method of manufacturing the shielded electrical connector assembly includes the steps of providing a single planar sheet of conductive material, providing a die and a punch, forming the sheet into a cupped shape having a main wall and four side walls surrounding the main wall using the die and the punch, and forming a side wall opening in one of the four side walls.

  • Patent number: 10527273
    Abstract: The present invention relates to different embodiments of lighting fixtures, such as high bay lighting fixtures, comprising improved features. One of these features can be a driver box placement that is displaced from the center of the fixture. In one such embodiment, the driver box can be mounted such that no portion is over the emitters. Another improved features is a heat sink with branching spokes. As they move away from the center of the heat sink, each of the spokes can branch into multiple spokes, which can improve conductive thermal dissipation. Empty spaces can be left between the spokes to improve convective thermal dissipation.
