Patent number: 10989861Abstract: A lighting fixture that includes a frame, a heat sink assembly, an LED assembly, and a reflector. The frame includes a first end plate and a second end plate, each end plate including a slot formed therein. The slot extends from a top edge of the end plates towards a bottom edge of the end plates. The heat sink assembly includes one or more LEDs and a lightguide having a first longitudinal edge that receives light emitted from the LEDs. A first edge and a second edge of the lightguide are slidably inserted into respective slots. The heat sink assembly includes a heat sink base and a heat sink cap coupled thereto which forms a first cavity for housing the LEDs and a second cavity adjacent the first cavity for housing a portion of the lightguide. The reflector is coupled to the end plates.Type: GrantFiled: September 30, 2019Date of Patent: April 27, 2021Assignee: SIGNIFY HOLDING B.V.Inventors: James H. Blessitt, Paul W. Lewis, Jr.

Publication number: 20200200378Abstract: A high bay lighting fixture includes an electronics housing and a light module that includes a light source that emits a light. The high bay lighting fixture further includes a tubular connector. The electronics housing is attached to the tubular connector at a first end of the tubular connector, and the light module is attached to the tubular connector at a second end of the tubular connector separated from the electronics housing by the tubular connector. The tubular connector provides a wireway for routing an electrical wire between the electronics housing and the light module.Type: ApplicationFiled: December 18, 2019Publication date: June 25, 2020Inventors: Audie T. Stokes, James H. Blessitt

Patent number: 10605978Abstract: An edgelit recessed luminaire includes a housing that defines an inner cavity and has a pair of side panels. Each side panel includes one or more torsion spring receivers. Further, the edgelit recessed luminaire includes a light engine that includes torsion springs that are pivotally coupled to the light engine via torsion spring brackets. The light engine is removably coupled to the housing such that in an open position, the light engine is suspended from the housing via the torsion springs providing access to the inner cavity and in a closed position, the light engine covers the inner cavity of the housing. Alternatively, a linear light module is removably coupled to the housing.Type: GrantFiled: December 19, 2017Date of Patent: March 31, 2020Assignee: Eaton Intelligent Power LimitedInventors: James H. Blessitt, Phillip Kim Sou, Grzegorz Wronski

Publication number: 20200081175Abstract: Embodiments described herein are directed to a lighting fixture including a lightguide that distributes light from a major surface, a light assembly including light sources arranged linearly, and a frame including a means for providing a force that urges the light assembly against an edge of the lightguide. A standoff or spacer can provide an air gap between a light source of the light assembly and the waveguide edge. In various embodiments, the lighting fixture may incorporate a spring, a spring finger, a spring clip, a screw, or other means for securing the light assembly against the edge of the lightguide. In this manner, substantially all light provided by the light assembly is emitted into the edge of the lightguide. The fixture is formed to accommodate tolerances among elements of the lighting fixture, while maintaining the light assembly securely against the edge of the lightguide.Type: ApplicationFiled: November 11, 2019Publication date: March 12, 2020Inventors: James H. Blessitt, Russ Clements, Ellis W. Patrick
