A universal mounting frame assembly for an optical assembly may comprise elements configured to accommodate both circular and square optical assemblies. For example, different shapes and sizes of luminaires and reflectors may be designed to accommodate a specific size and shape of optical assembly containing a specific configuration of one or more light sources. Accordingly, a universal mounting frame assembly for an optical assembly is required to accommodate each of a square and circular optical assembly.
According to one aspect, a luminaire may comprise: a mounting frame comprising a first attachment interface spaced apart from a second attachment interface; an aperture plate, coupled to the mounting frame at the first and second attachment interfaces, the aperture plate comprising a first aperture configured to receive a reflector assembly; a first mounting bracket adjustably-coupled to the first attachment interface, and a second mounting bracket adjustably-coupled to the second attachment interface, the first and second mounting brackets configured to provide adjustable coupling of the mounting frame to a ceiling structure between at least two positions along a vertical direction; and an optical assembly removably-coupled to the mounting frame, comprising at least one light source configured to emit light through the first aperture.
According to another aspect, a mounting frame assembly for use with coupling to an optical assembly, the mounting frame assembly may comprise: a mounting frame comprising a first attachment interface spaced apart from a second attachment interface, wherein the mounting frame is configured to support a junction box; an aperture plate, coupled to the mounting frame at the first and second attachment interfaces, the aperture plate comprising a first aperture configured to receive a reflector assembly; and a first mounting bracket adjustably-coupled to the first attachment interface, and a second mounting bracket adjustably-coupled to the second attachment interface, the first and second mounting brackets configured to provide adjustable coupling of the mounting frame to a ceiling structure between at least two positions along a vertical direction.
According to yet another aspect, a mounting frame assembly for use with coupling to an optical assembly, the mounting frame assembly may comprise: a mounting frame comprising a first attachment interface spaced apart from a second attachment interface, wherein the mounting frame is configured to support a junction box; an aperture plate, coupled to the mounting frame at the first and second attachment interfaces, the aperture plate comprising a first aperture configured to receive a reflector assembly, wherein the aperture plate is interchangeable with the mounting frame between a round aperture plate for a round optical assembly and a square aperture plate for a square optical assembly; and a mounting surface to couple a junction box to the mounting frame, wherein the mounting surface includes at least two lance tabs that are received in at least two slots located at a bottom of the junction box, and further wherein the at least two lance tabs include an angled portion that flexes and compresses upon insertion of the lance tabs into the slots and then expands when the lance tab is fully inserted into the slots, thereby preventing the junction box from being decoupled from the mounting surface without compressing the lance tabs.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. The Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

Further, it is to be understood that the drawings may represent the scale of different components of one single embodiment; however, the disclosed embodiments are not limited to that particular scale.
Aspects of this disclosure relate to a mounting frame assembly for use with coupling to an optical assembly, the mounting frame assembly may comprise: a mounting frame comprising a first attachment interface spaced apart from a second attachment interface, wherein the mounting frame is configured to support a junction box; an aperture plate, coupled to the mounting frame at the first and second attachment interfaces, the aperture plate comprising a first aperture configured to receive a reflector assembly; and a first mounting bracket adjustably-coupled to the first attachment interface, and a second mounting bracket adjustably-coupled to the second attachment interface, the first and second mounting brackets configured to provide adjustable coupling of the mounting frame to a ceiling structure between at least two positions along a vertical direction. Additionally, the mounting frame assembly may include a mounting surface to couple a junction box to the mounting frame, wherein a bottom of the junction box includes at least two lance tabs that are received in at least two slots located at the mounting surface, and further wherein the at least two lance tabs include an angled portion that flexes and compresses upon insertion of the lance tabs into the slots and then expands when the lance tab is fully inserted into the slots, thereby preventing the junction box from being decoupled from the mounting surface without compressing the lance tabs.
In the following description of the various embodiments, reference is made to the accompanying drawings, which form a part hereof, and in which is shown, by way of illustration, various embodiments in which aspects of the disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made without departing from the scope and spirit of the present disclosure.
The mounting frame assembly 102 may be configured to be coupled to an external support structure (not pictured in
In the foregoing, reference is made to the various elements as having one or more of a “top,” “bottom,” “front,” “back,” “left,” and/or “right” side, and/or a “horizontal,” or “vertical” orientation. However, these terms are merely associated with one example orientation used to aid in the description of the various elements of this disclosure. As such, the disclosed implementations in the foregoing are not limited to any one orientation. Similarly, the various elements described throughout this disclosure may be scaled in proportion to one another, such that the various implementations described herein may have any dimensional values. In another example, one or more elements described in this disclosure may be scaled disproportionately, and such that the accompanying Figures may not represent true proportions of the various elements described herein.
The present disclosure is disclosed above and in the accompanying drawings with reference to a variety of examples. The purpose served by the disclosure, however, is to provide examples of the various features and concepts related to the disclosure, not to limit the scope of the invention. One skilled in the relevant art will recognize that numerous variations and modifications may be made to the examples described above without departing from the scope of the present disclosure.
