  • Patent number: 11637419
    Abstract: A cable gland assembly includes a gland nut defining a longitudinal axis. The gland nut includes an interior wall defining a gland nut opening and the interior wall includes a stop. A bushing is disposed within the gland nut opening proximate the stop. The bushing defines a bushing opening configured to receive a cable therein. A sleeve is moveably disposed within the gland nut opening adjacent the bushing. The cable gland assembly also includes a body defining a body opening configured to receive at least a portion of the cable therein. The body is configured to couple to the gland nut, and upon tightening of the gland nut to the body, the gland nut moves along the longitudinal axis compressing the bushing between the gland nut and the sleeve and around the cable. When the sleeve engages with the stop, further compression of the bushing is restricted.

  • Patent number: 10584831
    Abstract: A light fixture is provided which includes a housing body onto which a bezel is attached. Semiconductor LEDs or other light emitting source that produce light when electrically powered are located behind a lens that is secured to the housing body by the bezel. One or more incandescent light bulbs that include an electric filament that produce light when electrified as well as one or more fluorescent bulbs that produce light based at least in part on the electrification and illumination of a plasma or gas can also be used as a source of illumination. For example, the light fixture can further include a driver housing that includes a driver housing cover to permit access to at least one driver and/or battery backup components located within the driver housing. There is also at least one window in the bezel which permits illumination of an area or object.

  • Patent number: 10454415
    Abstract: An electrical box includes a first electrical component having an output terminal, and a second electrical component having an input terminal. A jumper is connected to the output terminal of the first electrical component and the input terminal of the second electrical component. The jumper defines a heat flow path between the first and second electrical components. The heat flow path defines a minimum path between the first and second electrical components along the heat flow path. A minimum distance along the minimum heat path between the first and second electrical components is greater than a minimum distance between first and second electrical components.

  • Patent number: 10408442
    Abstract: A housing for a light fixture includes at least one wall that forms a cavity and a light source housing portion, where the at least one wall includes a thermally-conductive material, where the light source housing portion is configured to receive at least one light source. The housing can also include a wireway disposed between the cavity and the light source housing portion. The housing can further include multiple heat sink fins that extend from an outer surface of the at least one wall. The housing can also include at least one air throughway that exposes at least a portion of the wireway between the at least one wall and the light source housing portion, where the at least one air throughway allows air to pass over the portion of the wireway, where the at least one air throughway is formed independent of the heat sink fins.
