[0001] This patent application claims the priority benefit to European Patent Application No. 25171369.9, filed on April 17, 2025, which claims the priority benefit of U.S. Provisional Patent Application No. 63 / 723,228, filed on November 21, 2024 and U.S. Provisional Patent Application No. 63 / 782,093, filed on April 2, 2025, the contents of which are herein incorporated by reference.FIELD OF THE INVENTION

[0002] This invention relates to assemblies and methods for mounting electrical fixtures to suspended ceilings.BACKGROUND

[0003] Many building interiors employ suspended ceilings. Suspended ceilings are formed of structural grids and removable ceiling tiles. The components of the structural grids, i.e., grid members, and the removable ceiling tiles can be of various shapes and sizes, and arranged in various configurations. These variations result in numerous on-site variables that may be necessary to consider when installing electrical fixtures to the suspended ceiling.

[0004] Moreover, the suspended or false ceiling is formed of acoustical tiles or drywall tiles which are supported by a network of inverted T-shaped grid members. The T-grid members are supported from the building structure by a plurality of wires or stems and are typically formed of lightweight, small gauge sheet steel. Such construction minimizes the cost of the grid members, provides adequate structural support for the ceiling tiles, and allows adequate access to mechanicals. In construction of buildings, it is known to install false or suspended ceilings beneath water pipes, heating ducts and electrical races in order to easily access such structures while concealing them from normal activity within a building or room. Pre-existing piping, wiring, ductwork and insulation in the plenum space can further complicate the installation process.

[0005] In mounting light fixtures to the T-grid, various known light fixtures require the use of multiple tools in order to connect hanger bars to the inverted T-grid formed of a plurality of inverted T-bars. For example, current mounting systems have four mounting bar ends which must be attached to the inverted T-bar members by bending using pliers, adding wire, driving a screw into the T-bar or by snapping the hanger bars onto the T-grid and utilizing tools to adjust the height of the fixture relative to the acoustical tile ceiling members. Such activities are difficult in and of themselves, however, when working above the ceiling level on a ladder, the task is not only difficult, but may be unsafe.

[0006] Architectural design requirements typically demand mounting electrical fixtures to the suspended ceiling without compromising the structural, acoustic or visual integrity of the suspended ceiling. Predicting on-site mounting conditions can be difficult if not impossible for persons installing electrical fixtures, and hence the conventional requirement for installers to equip themselves with a variety of mounting devices to ensure proper installation.

[0007] Assemblies and methods for efficiently mounting electrical fixtures to suspended ceilings are desirable.SUMMARY OF THE INVENTION

[0008] These and other drawbacks of such conventional technologies are addressed here by providing a luminaire, such as a recessed downlight, with a hanger bar assembly for a luminaire, wherein the luminaire is configured to attach to a T-grid / suspended ceiling system. The hanger bar assembly may include a hanger bar member having a first T-bar attachment structure disposed on an end thereof and a second T-bar attachment structure disposed on an opposite end thereof. The hanger bar member is attached or integrated into one side the frame of the luminaire for connection of the frame to a suspended ceiling. The hanger bar assembly can also be used to attach any electrical component or other device to a T-grid / suspended ceiling system.

[0009] The first and the second attachment structures each include a horizontally extending portion with an adjustment hinge therein and a T-bar tab connected to the adjustment hinge. The hanger bar assembly is positionable against an upper surface of a suspended ceiling T-grid system and the T-bar tab is positionable against one side of a T-grid member, generally near a corner. The T-bar tab attaches to one side of the T-grid system. The T-bar tab include a hinge that is enables the T-bar tab to be adjusted or bent to allow it to be attached to the T-bar in one of six sides of a corner of the T-grid system.

[0010] The T-bar tab also has a first and second fastener aperture, the first and second fastener apertures being formed about a common central longitudinal axis. The T-bar clips also include a seismic wire hanger aperture about a common central longitudinal axis. The hanger bar assembly may also include a fastener and a second fastener, e.g. nails or screws, that engage the first and second fastener aperture.

[0011] The luminaire may be an LED luminaire. The LED luminaire may be a suspended and recessed LED luminaire.

[0028] FIGS. 1 and 2 illustrate a hanger bar assembly 100 according to a first embodiment for mounting an electrical fixture, for example a luminaire, to a suspended ceiling, in particular a T-grid / suspended ceiling system. The hanger bar assembly 100 includes a substantially horizontal hanger bar member 102 having a first end and a second end. Each end having a T-bar attachment structure 104 disposed thereon.

[0029] The hanger bar assembly 100 can be formed from sheet metal using a punch press or made of plastic.

[0030] The hanger bar member 102 is configured with attached points to enable attached to a luminaire, e.g. one side of a housing of a luminaire. The luminaire is configured for connection of the housing to a T-grid / suspended ceiling. The hanger bar member 102 and luminaire are secured together by any suitable means, such as by screws, rivets, or other mechanical couplings. The housing of the luminaire may include tabs receivable in corresponding slots of housing to facilitate coupling of the hanger bar assembly. The hanger bar member 102 is generally sized to extend from one T-bar hanger to another T-bar hanger.

[0031] As shown in FIG. 2, the T-bar attachment structures 104 includes a horizontally extending portion 108 coupled to the hanger bar member 102. An adjustment hinge 110 is configured on each end of the hanger bar horizontally extending portion 108 and a T-bar tab 112 connected to the adjustment hinge 110. The T-bar tab 112 extends downward from and substantially perpendicular to the hanger bar member 102. The T-bar tab 112 is configured to extend downward from the top of a T-bar hanger.

[0032] The length of the extending portion 108 is configured enable the T-bar tab 112 to be arranged using the adjustment hinge 110 such that it can be positioned to accommodate multiple situations where access is limited when a luminaire is coupled to the T-grid hanger system. As described above, installers face a number of obstacles during installation of T-grid hanger system, in particular, having plumbing, HVAC, electrical wiring (etc.) in the way. As further described with regard to FIGS. 6, the T-bar tab 112 is adjustable or bendable to be adjacent or face to one of six different sides of a T-Bar hanger intersection or corner of a T-grid hanger system. The hanger bar assembly 100 increases the installation flexibility and allows installers the ability to hand bend the T-grid tab around to a side of the T-Bar that is more accessible saving them time.
