Publication number: 20240035643Abstract: A lighting module includes a heat sink with a sidewall and a partition defining two cavities, a LED light source disposed in one cavity to emit light, a driver module disposed in the other cavity with driver circuitry to provide electrical power to the light source, and an optical assembly to provide a desired emission profile. The optical assembly is field-changeable and includes a cover lens with snap-fit connectors to facilitate removal and replacement. The optical assembly further includes either a reflector coupled to the cover lens or an optical lens coupled to the heat sink via an optic holder. In some examples, the driver circuitry facilitates dimming of the light source. The heat sink also dissipates heat generated by the light source and the driver circuitry to maintain desired operating temperatures and thereby facilitate increased light output.Type: ApplicationFiled: February 20, 2023Publication date: February 1, 2024Applicant: DMF, Inc.Inventors: Frederick William Kopitzke, Nolan Gunsolley, Amir Lotfi, Benjamin Pin-Chun CHEN

Publication number: 20230040032Abstract: A lighting module includes a heat sink having a sidewall and a partition that define a first cavity and a second cavity. A driver enclosure is disposed in the first cavity to electrically insulate a driver from the heat sink. The driver enclosure substantially fills and covers the first cavity. A light source that emits light is disposed in the second cavity together with an optical element that redirects the light. A retaining ring/optic cover covers and encloses the second cavity. The lighting module is shaped and/or dimensioned to fit into a space having a width less than 2.4 inches, a height less than 2.25 inches, and/or a volume as small as 18 cubic inches. The heat sink may also include a receptacle to couple a trim to thermally and electrically couple the trim to the heat sink to dissipate heat and to ground the trim.Type: ApplicationFiled: March 14, 2022Publication date: February 9, 2023Applicant: DMF, Inc.Inventors: Michael D.

Patent number: 11448384Abstract: An adjustable lighting apparatus includes a lighting module that is rotatably adjustable about a first rotation axis relative to an adjustable mount. The lighting module may include a heat sink, a driver, and a light source. The adjustable mount may include a base structure, a retainer, a shield, and a secondary shield. A trim may also be coupled to the adjustable mount. In some implementations, the lighting module translates along a first translation axis defined by the adjustable mount while rotating about the first rotation axis in order to reorient the light source while reducing shading losses caused by the adjustable mount. Openings in the base structure and the shield may be substantially covered at all rotational positions of the lighting module using a combination of the shield, the trim, the heat sink, and the secondary shield, thus eliminating the need for an additional enclosure.Type: GrantFiled: May 26, 2020Date of Patent: September 20, 2022Assignee: DMF, Inc.Inventors: Ali A.

Patent number: 11391442Abstract: A recessed lighting system includes multiple components formed from a polymer to reduce the number of components in the system, lower the cost of manufacture, and simplify the installation of the recessed lighting system. In one example, a recessed lighting system includes a housing formed from a polymer, a hanger bar assembly, a light module, and a trim. A yoke may be installed into the housing to provide greater accessibility to mount the light module and/or trim to the housing. A partition plate may be installed to push back wires/cables disposed in the housing such that the cavity of the housing is divided into a wiring compartment containing the wires/cables and a lighting compartment containing the light module and the trim. A hanger bar assembly may also be coupled to the housing to couple the recessed lighting system to a building structure (e.g., a T-bar, a joist, a stud).Type: GrantFiled: December 11, 2020Date of Patent: July 19, 2022Assignee: DMF, Inc.Inventors: Michael D.
