Embodiments of the disclosure relate generally to lighting solutions, and more particularly to technology for mounting a luminaire, such as to a junction box or other structure.
BACKGROUND
Luminaires are often positioned adjacent or above an area to be illuminated, such as a room, a space frequented by people, or other location. Utilizing conventional mounting approaches, such luminaires are often cumbersome or inefficient in terms of installation and/or service. Additionally, conventional luminaire mounting systems often expose the illuminated area to fastening elements that are either unsightly, distracting, or expensive to produce in a form that is sightly.
Improved technology for mounting luminaires in needed. Need exists for improved efficiency of installation and service. Need exists for improved manufacturing economics. Need exists for improved simplicity and reduction in part count. Need exists for a capability to improve visual appeal of luminaires and their associated mounting facilities. Further need exists for improvements in terms of reliability, economy, usability, simplicity, compactness, and visual appeal, for example.
A capability addressing one or more such needs, or some other related deficiency in the art, would support economical illumination systems.
SUMMARY
A luminaire can be mounted to a junction box or other structure that may be disposed adjacent a ceiling, wall, or other surface. A bracket can be attached to the junction box or other structure, using one or more fasteners. The bracket can comprise two protrusions, and the luminaire can comprise two corresponding apertures. Alternatively, the bracket can comprise two apertures, and the luminaire two corresponding protrusions. The luminaire can be attached to the bracket by positioning the luminaire so that the two protrusions are aligned with the two apertures and then moving the luminaire so the apertures and protrusions engage. For example, the two protrusions may comprise two tabs, and the two apertures may comprise two slots. Such tabs and slots can engage and lock via rotation of the luminaire relative to the bracket, for example.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
Embodiments of the disclosure are directed to systems, methods, and devices for connecting a luminaire to a junction box or other member. The systems and methods described herein may provide multiple advantages. Some embodiments provide installation of a luminaire to a junction box or other structure using mounting components that are hidden from view once the luminaire is installed. Some embodiments provide installation without custom tools to remove elements of the luminaire, such as lens, that are visible after installation. Some embodiments facilitate installation alternatives supporting a variety of luminaire types.
Embodiments of the disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like numbers refer to elements that are like, but not necessarily identical, throughout.
FIGS. 1-6 illustrate representative features for a first example embodiment. FIGS. 7 and 8 illustrate representative features for a second embodiment. FIGS. 9-19 illustrate representative features for some embodiments that utilize a two-tab mounting bracket and are similar to the first example embodiment from FIGS. 1-6. FIGS. 20-32 illustrate representative features for some embodiments utilizing a three-tab mounting bracket.
Some example embodiments in accordance with FIGS. 1-6 will now be discussed.
FIG. 1 illustrates a perspective view of a mounting bracket 100 installed to a junction box 105 and an uninstalled luminaire 110 below a ceiling 115 in accordance with an example embodiment of the disclosure. In a typical installation, the junction box 105 is mounted in or above a hole 150 in the ceiling 115 using nails, screws, fasteners, hangar bars, friction springs or brackets, or other appropriate mounting system. As will be discussed in further detail below, the mounting bracket 100 attaches to the junction box 105, and the luminaire 110 attaches conveniently to the mounting bracket 100.
The example mounting bracket 100 shown in FIG. 1 is shaped to accommodate low profile luminaires 110. As shown in FIG. 1, one example luminaire 110 may have a large diameter and non-removable parts (e.g., a lens, trim, etc.) that would be visible after installation. In the illustrated embodiment, a center portion of the mounting bracket 100 is sized for insertion in the hole 150, while another, outer portion protrudes from the hole 150 and is sized so that its insertion in the hole is obstructed in the intended orientation. In the illustrated embodiment, the luminaire 110 is also sized larger than the hole 150.
The mounting bracket 100 may be shaped as appropriate for various luminaire shapes including various low profile luminaires, such as the luminaire 110 shown in FIG. 1. Once the luminaire 110 is installed to the mounting bracket 100 the mounting bracket 100 is not visible from below the installed luminaire 110, and in the illustrated embodiment, is hidden behind a circumscribing rim 111 of the luminaire 110.
FIG. 2 illustrates a side view of the mounting bracket 100 installed to the junction box 105 and the uninstalled luminaire 110 below the ceiling 115 in accordance with an example embodiment of the disclosure. As shown in FIG. 2, a power system 220 may be located on the back of the luminaire 110. The power system 220 may comprise power circuitry, a power enclosure, or other protruding enclosure or element of the luminaire 110, such as a driver for a luminaire based on light emitting diode (LED) technology.
The mounting bracket 100 may be shaped to accommodate such a power system 220 or other protruding features located on the back of the luminaire 110. This space clearance provided by the shaping of the mounting bracket 100 provides a receptacle and supports the junction box 105 housing components such as the power system 220 in the junction box 105. More particularly, the mounting configuration of FIG. 2 can be viewed as nested, with the power system 220 disposed in a receptacle of the mounting bracket 100, and the receptacle of the mounting bracket 100 disposed in the junction box 105.
In addition to functional benefits, the illustrated configuration can provide an aesthetically pleasing installed luminaire 110 as viewed from below the ceiling 115. In some example embodiments, such accommodation of protruding features on the back of the luminaire 110 facilitates an installation of the luminaire 110 that is flush or nearly flush to the bottom of the ceiling 115.
FIG. 3 illustrates the mounting bracket 100 with two mounting tabs 305 that lock in accordance with an example embodiment of the disclosure. As shown in FIG. 3, the example mounting bracket 100 has two mounting tabs 305 that engage with a back portion of the luminaire 110 when the luminaire 110 is lifted into position. In various embodiments, the engagement may comprise mating with, locking into, pushing against, snapping, plugging, a slot-and-tab connection, or some other appropriate form of mechanical linkage, connection, or fastening.
With the example mounting bracket 100 shown in FIG. 3, the luminaire 110 is rotated to engage the mounting tabs 305 with features located on the luminaire 110, examples of which will be described in further detail below with reference to additional figures. In various embodiments of the disclosure, other mounting brackets may have more or less than two mounting tabs 305. For instance, some bracket embodiments may have three mounting tabs. The mounting bracket 100 may be made out of stamped metal or a variety of other appropriate materials (for example, die castings, plastic, steel, or other materials).
FIG. 4 illustrates a perspective view of a mounting bracket 100 with two mounting tabs 305 installed to the junction box 105 in accordance with an example embodiment of the disclosure. As shown in FIG. 4, the mounting bracket 100 may be attached to the junction box 105 with one or more fasteners, for example screws, rivets, pins, clips, or other appropriate devices, via fastener holes 415, 420 located in the mounting bracket 100.
As shown in FIG. 4, the mounting bracket 100 may have multiple fastener holes 415 to accommodate existing receiving means (for example screw holes, etc.) on the junction box 105, or to allow for new attachments to be made to portions of the junction box 105. With such flexibility, the mounting bracket 100 can accommodate junction boxes 105 of various shapes and sizes, junction boxes 105 made of various materials (for example metal, plastic, etc.), or junction boxes 105 used in new construction or remodeling. Additionally, the mounting bracket 100 may be attached to other structures mounted at, in, or above the ceiling 115.
The bends provided in the mounting bracket 100 shown in FIG. 4 facilitate placing portions of the mounting bracket 100 inside the junction box 105 above the ceiling plane. Thus, the installed bracket 100 provides space clearance to receive a portion of the luminaire 110 that may be protruding from the back side of the luminaire 110, for example a power supply 220, such as a driver for an LED-based luminaire. Additionally, this space may retain house wiring towards the back of the junction box 105 to aid in installation by providing clearance.
In alternative embodiments to the single piece construction shown in FIG. 4, the mounting bracket 100 can be made of multiple pieces or various materials, for example, the mounting tabs 305 may be separate from the mounting bracket 100 and/or made of different material than the other portions of the mounting bracket 100.
FIG. 5 illustrates a perspective view of the mounting bracket 100 installed to the junction box 105 with the luminaire 110 positioned so that luminaire slots 510 are aligned with the bracket mounting tabs 305 in accordance with an example embodiment of the disclosure. As shown in FIG. 5, the bracket mounting tabs 305 fit into slots 510 located on the back of the luminaire 110, specifically on a rear side of the rim 110 the luminaire 110.
In the illustrated embodiment, when the luminaire 110 is rotated, the bracket mounting tabs 305 slide past a locking feature 525 (in this example a protrusion or bump) on the profile of the slot 510 to lock the luminaire 110 into place and may hinder the luminaire 110 from rotating back. In the embodiment of the disclosure shown in FIG. 5, the angles on the bracket mounting tab 305 and locking feature 525 facilitate disassembly, for example in connection with servicing the luminaire 110. The luminaire 110 may be un-installed by rotating the luminaire 110 back by hand or otherwise.
Accordingly, the luminaire 110 can be installed to the mounting bracket 100 without necessarily removing any lens or other covering of the luminaire 110, and the fastening system is hidden. Similarly, the luminaire 110 can be readily removed from the mounting bracket 100 without necessarily disassembly of the luminaire 110.
In alternative embodiments, the engagement between the mounting bracket 100 and luminaire 110 may be reversed with the mounting bracket 100 containing the slots 510 and the luminaire 110 containing the mounting tabs 305, while still supporting rotation of the luminaire 110 for slot-tab engagement to fix the luminaire 110 in place.
FIG. 6 illustrates the bracket mounting tab 305 in locked position in the luminaire slot 510 in accordance with an example embodiment of the disclosure. As shown in the example embodiment of FIG. 6, when the luminaire 110 is rotated in relation to the bracket 100, the luminaire 110 becomes held or locked in place. A locking feature 535 of the luminaire slot 510 engages with a bend 603 of the bracket mounting tab 305 located towards one end of the mounting bracket tab 305. A notch 615 of the luminaire slot 510 further engages with another portion of the bracket mounting tab 305.
In one example embodiment of the disclosure, when the luminaire 110 is rotated in relation to the mounting bracket 100, the bracket mounting tab 305 is guided to the correct installation position in the luminaire slot 510 based on the length between the notch 615 and locking feature 525 of the slot 510 and/or the shape of the perimeter of the slot 510. As installed, the luminaire 110 is centered on the mounting bracket 100 when installed. Other configurations of the bracket mounting tab 305 or luminaire slot 510 may be used in alternative embodiments of the disclosure to create other mating or locking relationships between a protrusion such as the tab 305 and an aperture such as the slot 510 when the luminaire 110 is rotated in relation to the mounting bracket 100 during installation.
Some example embodiments in accordance with FIGS. 7 and 8 will now be discussed.
Whereas the example mounting bracket 100 illustrated in FIGS. 1-6 has two opposing arms, each with a radially disposed bracket mounting tab 305, the mounting bracket 713 in the embodiment of FIGS. 7 and 8 comprises a disk 712 with three radially disposed bracket mounting tabs 700.
FIG. 7 illustrates a perspective view of the bracket mounting tabs 700 aligned to but not yet engaged with luminaire receivers 705. In a typical embodiment, the each tab 700 comprises a protrusion, and each receiver 705 comprises an aperture.
When the luminaire 710 is rotated, the receivers 705 engage with the bracket mounting tabs 700 to friction hold or lock the luminaire in place. FIG. 8 illustrates a perspective view of the bracket mounting tabs 700 engaged with the luminaire receivers 705 in accordance with an example embodiment of the disclosure.
In alternative embodiments, the engagement between the mounting bracket 713 and the luminaire 710 may be reversed with the mounting bracket 713 containing the receivers 705 and the luminaire 710 containing the mounting tabs 700. In such an alternative configuration (among other alternatives), rotation of the luminaire 710 causes the receivers 705 and tabs 700 to engage and fix the luminaire 710 in place.
Some example embodiment utilizing a two-tab mounting bracket will now be described with reference to FIGS. 9-19.
FIG. 9 illustrates a side view of a two-tab mounting bracket 900 and associated luminaire 905 in accordance with an example embodiment of the disclosure.
