TECHNICAL FIELD
Embodiments of the present disclosure relate generally to light fixtures, and more particularly to recessed luminaires and components associated with the recessed luminaires.
BACKGROUND
Luminaires, such as ceiling-mounted, wall-mounted, or surface-mounted luminaires, commonly illuminate spaces in which people live, work, or play. One type of luminaire is the recessed luminaire, which is installed within an aperture formed in a ceiling. Typically, recessed luminaires may include at least: (a) a housing, such as a cylindrical can (herein ‘recessed can’) that defines a cavity, (b) a light source disposed in the cavity and oriented to emit light through an opening of the recessed can into the illumination area, such as a room, and (c) a finishing section that is disposed within the cavity of the recessed can and below the light source such that an integrated flange or a non-integrated trim ring of the finishing section may be disposed below and engage the ceiling to cover any space formed between a perimeter of the opening of the recessed can and a perimeter of the aperture formed in the ceiling. However, the integrated flange and/or trim ring of the finishing section can be aesthetically unappealing to an observer standing in the illuminated space. Further, cracks may be formed in the ceiling adjacent the aperture in the ceiling within which the recessed can is installed due to vibrations, thermal expansions or contractions, etc., of the recessed luminaire to the ceiling.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
In the following paragraphs, recessed luminaires and one or more components associated with the recessed luminaires that provide options to install different types of finishing sections for a flanged and/or flangeless appearance will be described in further detail by way of examples with reference to the attached drawings. In the description, well known components, methods, and/or processing techniques are omitted or are briefly described so as not to obscure the disclosure. As used herein, the “present disclosure” refers to any one of the embodiments of the disclosure described herein and any equivalents. Furthermore, reference to various feature(s) of the “present disclosure” is not to suggest that all embodiments must include the referenced feature(s).
In one example, the components associated with the recessed luminaire include a lathing ring that is coupled to a ceiling. The lathing ring may be used when a recessed luminaire installation that provides a flangeless appearance to the recessed luminaire finishing section is desired. Also, the lathing ring provides additional support to the ceiling around the aperture in the ceiling within which the recessed luminaire is installed. Further, the lathing ring prevents direct transfer of vibrations, thermal expansions, thermal contractions, etc., of the recessed luminaire to the ceiling, thereby avoiding the formation of cracks in the ceiling and preserving a structural integrity of the ceiling.
The lathing ring may include a collar that defines an opening, an external perforated flange that extends radially outward from the collar, and an inner flange that extends radially inward towards the opening and substantially perpendicular to the collar. Further, the collar includes one or more through apertures for coupling fold-over tabs to the lathing ring using fasteners. The fold-over tabs are configured to couple the lathing ring to the ceiling. Alternatively, the lathing ring may be designed to snap onto a recessed luminaire housing, thereby making the installation of the lathing ring independent of the ceiling (particularly, the thickness of the ceiling). The snap fit lathing ring may include one or more snap tabs that are configured to engage corresponding notches in the recessed luminaire housing.
In addition to the lathing ring, the components associated with the recessed luminaire include a rimless recessed luminaire housing and one or more flange clips that can be removably coupled to the rimless recessed luminaire housing such that the flanges of the one or more flange clips extend radially outward from a bottom edge of the recessed luminaire housing. The rimless recessed luminaire housing with the one or more flange clips coupled thereto is installed in the ceiling that is fitted with the lathing ring. The flanges of the one or more flange clips assist with the installation of the rimless recessed luminaire housing in the ceiling, particularly, to align and to prevent over-insertion of the rimless recessed luminaire housing in the ceiling during installation.
Instead of the rimless recessed luminaire housing, in some examples, the components associated with the recessed luminaire include a rimmed recessed luminaire housing and a detachable flange ring that is removably coupled to the rimmed recessed luminaire housing to align and to prevent over-insertion of the rimmed recessed luminaire housing in the ceiling during installation. The rimmed recessed luminaire housing with the detachable flange ring is configured to be installed in the ceiling without the lathing ring. The rimmed recessed luminaire housing with the detachable flange ring allows the installation of finishing sections that have a narrower or shorter integrated flange or non-integrated trim ring than conventional recessed luminaires.
The technologies of the present disclosure can 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 technology to those having ordinary skill in the art. Furthermore, all “examples” or “example embodiments” given herein are intended to be non-limiting and among others supported by representations of the present technology.
Moving now to discuss the figures, FIGS. 1-12 will describe an example embodiment of a recessed luminaire having a rimmed recessed luminaire housing and a detachable flange ring; FIGS. 13-23 will describe another example embodiment of a recessed luminaire having a rimmed recessed luminaire housing that is installed in a ceiling fitted with a lathing ring for providing a flangeless appearance of a finishing section; FIGS. 24-38 will describe yet another example embodiment of a recessed luminaire having a rimless recessed luminaire housing and one or more flange clips for installation in a ceiling fitted with the lathing ring; and FIGS. 39-46 will describe a snap fit lathing ring.
Recessed Luminaire with a Rimmed Housing can and a Detachable Flange Ring for Installation of Finishing Sections Having Narrower Flange/Trim Ring
FIG. 1 illustrates a perspective view of a rimmed housing can and a detachable flange ring of a first example housing assembly of a recessed luminaire, in accordance with example embodiments of the present disclosure; FIGS. 2-4 illustrate how the detachable flange ring is coupled to a rimmed housing can to form the first example housing assembly of the recessed luminaire, in accordance with example embodiments of the present disclosure; FIG. 5 illustrates a perspective view of the first example housing assembly of the recessed luminaire with a pawl assembly coupled thereto, in accordance with example embodiments of the present disclosure; FIG. 6 illustrates a perspective view of a plaster ground plate disposed on a ceiling, in accordance with example embodiments of the present disclosure; FIGS. 7-9 illustrate an installation of the first example housing assembly of the recessed luminaire in the ceiling, in accordance with example embodiments of the present disclosure; FIGS. 10-11 illustrate an installation of a first example finishing section in the first example housing assembly of the recessed luminaire, in accordance with example embodiments of the present disclosure; and FIG. 12 illustrates an example cross-section view of the recessed luminaire with the first example housing assembly installed in the ceiling and the first example finishing section disposed in the first example housing assembly, in accordance with example embodiments of the present disclosure.
Referring to FIGS. 1-12, a housing assembly 100 of a recessed luminaire may include a rimmed recessed luminaire housing 102 (herein ‘rimmed housing can 102’) that has a substantially cylindrical side wall 106 and a rim 108 that extends radially outward and substantially perpendicular to the side wall 106 from a bottom edge of the side wall 106. Alternatively, in other example embodiments, the rimmed recessed luminaire housing 102 may have a side wall having any other appropriate geometric or non-geometric shape without departing from a broader scope of the present disclosure. For example, the side wall 106 may taper towards the top by as much as five degrees. Similarly, in other example embodiments, the rim 108 may be inclined upwards or downwards at an angle without departing from a broader scope of the present disclosure.
The side wall 106 of the rimmed housing can 102 may define a substantially cylindrical cavity 124 that is configured to house a light assembly 3804 (shown in FIG. 38) of the recessed luminaire and/or electrical components associated with the light assembly 3804. Further, the bottom edge of the side wall 106 may define a light emitting opening 125 that provides access to the cavity 124 and allows light emitted by a light source of the light assembly 3804 to exit to an illumination area, such as a room. In addition to the light emitting opening 125, the side wall 106 of the rimmed housing can 102 may include one or more mounting assembly openings 110 to receive a respective retention system, such as a pawl assembly 519 (shown in FIG. 5). The pawl assembly 519 is an example retention system and one of ordinary skill in the art can understand and appreciate that the pawl assembly 519 can be replaced by any other appropriate retention system, such as remodel springs, other non-spring based retention systems, etc., without departing from a broader scope of the present disclosure.
The side wall 106 of the rimmed housing can 102 may also include one or more coupling apertures 119 that are disposed around each mounting assembly opening 110 for coupling the pawl assembly 519 to the rimmed housing can 102 using appropriate fasteners, such as screws, rivets, etc. For example, as illustrated in FIG. 5, the pawl assembly 519 may include a pawl housing 502 that is coupled to the side wall 106 of the rimmed housing can 102 by aligning coupling apertures 509 on the pawl housing 502 with the coupling apertures 119 of the side wall 106 and passing fasteners (not shown) therethrough. The pawl assembly 519 also includes a threaded screw 506 that passes through the pawl housing 502 and a pawl 504 that is coupled to the threaded screw 506. The pawl assembly 519 may be configured to mount the rimmed housing can 102 in the ceiling 602 (shown in FIG. 6) as will be described in greater detail below in association with FIGS. 7-9. Furthermore, the side wall 106 of the rimmed housing can 102 may also include one or more locking projections 112 that are disposed adjacent the rim end of the rimmed housing can 102 and extend out from an external surface of the side wall 106.
In addition to the side wall 106 and the rim 108, the rimmed housing can 102 includes a top surface 239 that extends radially inward from a top edge of the side wall 106 towards the cavity 124. The top surface 239 may define a heat sink opening 202 to receive a heat sink assembly 3802 (shown in FIG. 38) therethough. The heat sink assembly 3802 may be thermally coupled to the light module 3804 and configured to transfer heat away from the light module 3804 that is disposed in the cavity 124 formed by the side wall 106 of the rimmed housing can 102. The heat sink assembly 3802 and/or the light module 3804 may be coupled adjacent the top surface 239 of the rimmed housing can 102 using fasteners that are passed through the coupling apertures 204 disposed on the top surface 239 of the rimmed housing can 102.
In addition to the rimmed housing can 102, the housing assembly 100 of the recessed luminaire may include a detachable flange ring 104. As illustrated in FIG. 1, the detachable flange ring 104 may include an inner annular edge 116 that defines an opening 118, an outer annular edge 114, and a ring body 199 disposed between inner annular edge 116 and the outer annular edge 114. The ring body 199 may have a substantially Z-shaped cross-sectional profile (shown in FIG. 12) that includes a planar coupling base 122 and a flange 129 that is disposed adjacent to and below the planar coupling base 122. Further, the ring body 199 may include one or more notches 120 that are formed in the planar coupling base 122 and along the inner annular edge 116. The diameter of the opening 118 defined by the detachable flange ring 104 may be larger than the diameter of the substantially cylindrical side wall 106 of the rimmed housing can 102 to allow the detachable ring 104 to be disposed over and around the side wall 106 of the rimmed housing can 102 as illustrated in FIGS. 2-4.
Referring to FIGS. 2-4, the detachable flange ring 104 may be removably coupled to the rimmed housing can 102 by inserting the substantially cylindrical side wall 106 of the rimmed housing can 102 through the opening 118 defined by the detachable flange ring 104 as illustrated in FIG. 2. While inserting the rimmed housing can 102 through the opening 118 defined by the detachable flange ring 104, the notches 120 formed in the planar coupling base 122 of the detachable flange ring 104 may be aligned with the locking projections 112 on the side wall 106 of the rimmed housing can 102 to allow the detachable flange ring 104 to pass over the locking projections 112 as illustrated in FIG. 3. Once the detachable flange ring 104 passes over the locking projections 112 on the side wall 106, the rim 108 of the rimmed housing can 102 may engage the detachable flange ring 104 such that: (a) the planar coupling base 122 of the detachable flange ring 104 rests on the rim 108 of the rimmed housing flange 102, and (b) the flange 129 of the detachable flange ring 104 may be flush with the rim 108 of the rimmed housing can 102 and extend radially outward from the rim 108 of the rimmed housing can 102. Then, the detachable flange ring 104 may be locked and securely coupled to the rimmed housing can 102 by rotating the detachable flange ring 104 such that the notches 120 formed in the planar coupling base 122 of the detachable flange ring 104 are not aligned with the locking projections 112 on the side wall 106 of the rimmed housing can 102 as illustrated in FIG. 4.
To decouple the detachable flange ring 104 from the rimmed housing can 102, the detachable flange ring 104 may be rotated such that the notches 120 of the detachable flange ring 104 align with the locking projections 112 of the rimmed housing can 104. Then, the detachable flange ring 104 may be pulled up and removed from the rimmed housing can 102.
Once the detachable flange ring 104 is removably coupled to the rimmed housing can 102, the flange 129 of the detachable flange ring 104 may act as an extension of the rim 108 of the rimmed housing can 102. In particular, the flange 129 of the detachable flange ring 104 may be configured to assist with alignment and installation of the rimmed housing can 102 in the ceiling 602. For example, the detachable flange ring 104 may prevent an over-insertion of the rimmed housing can 102 in the ceiling 602 when the flange 129 of the detachable flange ring 104 engages the ceiling 602 as illustrated in FIG. 8. The diameter of the rimmed housing can 102 including the rim 108 may be lesser than the diameter of the aperture 606 (shown in FIG. 6) in the ceiling 602. Accordingly, during installation, if the rimmed housing can 102 is inserted through the aperture 606 in the ceiling 602 without the detachable flange ring 104, the rimmed housing can 102 may pass through the aperture 606 in the ceiling 602 without being impeded. However, when the detachable flange ring 104 is coupled to the rimmed housing can 102, the flange 129 of the detachable flange ring 104 may be wide enough to engage the ceiling 602 and act as a stop mechanism to prevent over-insertion and allow proper installation of the rimmed housing can 102 in the ceiling 602.
The width of the flange 129 of the detachable flange ring 104 may be configured to be just enough to engage the ceiling 602, thereby allowing an installation of a finishing section 1002 having a narrower trim flange 1004 (shown in FIG. 10) than conventional recessed luminaires. Detachable flange rings with a wider flange may be used. However, such detachable flange rings with wider flanges may require a finishing section with a wider flange to conceal the flange 129 of the detachable flange rings 104 and/or the rim 108 of the rimmed housing can 102. Finishing sections with wider flanges may be aesthetically unappealing to an observer in an illumination area and therefore undesirable.
Additionally, the detachable flange ring 104 allows the same rimmed housing can 102 to be used in other recessed lighting installations. For example, the detachable flange ring 104 may be coupled to the rimmed housing can 102 for an installation that allows a finishing section having a narrower flange to be coupled to the recessed housing can 102 as illustrated in FIGS. 1-12. In other examples, the detachable flange ring 104 may be removed for using the same rimmed housing can 102 in flangeless installations as illustrated in FIGS. 13-23.
Referring to FIGS. 6-9, the rimmed housing can 102 with the detachable flange ring 104 and the pawl assembly 519 may be installed in the ceiling 602 by inserting the rimmed housing can 102 through the aperture 606 in the ceiling 602 till the flange 129 of the detachable flange ring 104 engages a bottom surface 602b (surface that is visible to an observer in the illumination area, such as a room) of the ceiling 602. As illustrated in FIG. 6, a plaster ground plate 604 may be disposed on the ceiling 602 for ceiling adjustments and T-grid installations. In particular, the plaster ground plate 604 may be disposed on the top surface 602a of the ceiling 602 such that an opening 608 in the plaster ground plate 604 is aligned with the aperture 606 of the ceiling 602. It is noted that hanger bars are omitted from FIG. 6 for the sake of clarity, i.e., to clearly illustrate the plaster ground plate 604. Once the rimmed housing can 102 is inserted in the ceiling 602 and the flange 129 of the detachable flange ring 104 engages the ceiling 602, as illustrated in FIG. 9, the pawl 504 of the pawl assembly 519 that is coupled to the rimmed housing can 102 may be adjusted such that the pawl 504 engages the top surface 602a of the ceiling 602 (or the plaster ground plate 604) and clamps the ceiling 602 between the pawl 504 and the flange 129 of the detachable flange ring 104. Then, as illustrated in FIGS. 10-11, the finishing section 1002 may be coupled to the rimmed housing can 102 by inserting the finishing section 1002 in the cavity 124 defined by the rimmed housing can 102 till the trim flange 1004 of the finishing section engages the bottom surface 602b of the ceiling 602 and conceals the flange 129 of the detachable flange ring 104 and the rim 108 of the rimmed housing can 102. The finishing section 1002 may be retained in the rimmed housing can 102 by friction using friction clips 1008 that engage the inner surface of the rimmed housing can's side wall 106 as illustrated in FIG. 12. The friction clips 1008 may be coupled to the top collar 1010 of the finishing section 1002 that extends radially outward from a top annular edge of a body 1006 of the finishing section 1002.
Even though the present disclosure describes a plaster ground plate 604 being installed on the ceiling 602, one of ordinary skill in the art can understand and appreciate that in other example embodiments, the plaster ground plate 604 may be omitted without departing from a broader scope of the present disclosure. Further, even though FIGS. 1-12 describe the rimmed housing can 102 being used along with the detachable flange ring 104 in a recessed luminaire installation where the trim flange 1004 of the finishing section 1002, though narrower than in conventional recessed luminaires, is still visible; one of ordinary skill in the art can understand and appreciate that in other example embodiments, the rimmed housing can 102 can be used in other types of installations, such as recessed luminaire installations that provide a flangeless appearance to the finishing section without departing from a broader scope of the present disclosure. For example, the rimmed housing can 102 may be used with a lathing ring 1300 in a recessed luminaire installation that provide a flangeless appearance to the finishing section, as illustrated in FIGS. 13-23.
Recessed Luminaire with a Rimmed Housing can and a Lathing Ring for Providing a Flangeless Appearance to a Finishing Section Installed in the Rimmed Housing can
FIG. 13 illustrates a perspective view of a lathing ring, in accordance with example embodiments of the present disclosure; FIG. 14 illustrates a cross-section view of the lathing ring of FIG. 13, in accordance with example embodiments of the present disclosure; FIG. 15 illustrates a perspective view of the lathing ring of FIG. 13 with the fold-over tabs coupled thereto, in accordance with example embodiments of the present disclosure; FIGS. 16-18 illustrate how the lathing ring is installed in the ceiling using the fold-over tabs, in accordance with example embodiments of the present disclosure; FIGS. 19-20 illustrate an installation of a second example rimmed housing can of the recessed luminaire in the ceiling fitted with the lathing ring, in accordance with example embodiments of the present disclosure; FIGS. 21-22 illustrates an installation of a second example finishing section in the second example rimmed housing can of the recessed luminaire which in turn is installed in the ceiling fitted with the lathing ring, in accordance with example embodiments of the present disclosure; and FIG. 23 illustrates an example cross-section view of the recessed luminaire with the second example rimmed housing can installed in the ceiling fitted with the lathing ring and the second example finishing section disposed in the second example rimmed housing can, in accordance with example embodiments of the present disclosure.
Referring to FIGS. 13-23, the lathing ring 1300 may include an annular collar 1313 that defines an opening 1319. The annular collar 1313 may extend from a top annular edge 1321 to a bottom annular edge 1323 and has an inner surface 1313a and an outer surface 1313b. Further, the lathing ring 1300 may include an outer flange 1301 that extends radially outward from the outer surface 1313b of the annular collar 1313 (herein ‘collar 1313’). The outer flange 1301 may extend slightly upward forming an acute angle with the collar 1313 and may be slightly feathered to the outer edge 1302 allowing for an even transition to a ceiling surface (e.g., bottom surface 602b of ceiling 602). In certain example embodiments, the outer edge 1302 of the outer flange 1301 may define an octagonal shape as illustrated in FIG. 13. However, in other example embodiments, the outer edge 1302 of the outer flange 1301 may define any other appropriate non-geometric or geometric shape, such as circle, rectangle, square, etc., without departing from a broader scope of the present disclosure.
Further, the outer flange 1301 of the lathing ring 1300 may include a plurality of perforated openings 1312 that are formed circumferentially around the outer flange 1301 and extend through the thickness of the outer flange 1301. The perforated openings 1312 facilitate plastering on the outer flange 1301 since these perforated openings 1312 provide an area for the plaster to adhere itself. Additionally, the outer flange 1301 may include one or more mounting holes 1310 formed around and through the outer flange 1301. The one or more mounting holes 1310 may be configured to receive fasteners 1702 therethrough to couple the lathing ring 1300 to the ceiling 602 as illustrated in FIGS. 17, 18, and 23.
Furthermore, the lathing ring 1300 may include an inner flange 1316 that is disposed above the outer flange 1301 and extends radially inward towards the opening 1319 from the inner surface 1313a of the annular collar 1313. The inner flange 1316 may have a first set of notches 1318 formed therein to allow the pawl 504 coupled to the rimmed housing can 102 to pass therethough without being impeded by the inner flange 1316 during installation of the rimmed housing can 102 in the ceiling 602. Additionally, the inner flange 1316 may have a second set of notches 1325 formed therein to allow a portion of one or more flange clips (2502/2602) (shown in FIGS. 25 and 36) to pass therethrough while impeding the feet/flange portion of the flange clips 2502 or 3602 during installation to prevent over-insertion of the housing assembly as will be described in FIGS. 28-32. Also, the inner flange 1316 of the lathing ring 1300 may be narrower than the outer flange 1301.
Even though the present disclosure describes the inner flange 1316 of the lathing ring 1300 as having a first set of notches 1318 and a second set of notches 1325, one of ordinary skill in the art can understand and appreciate that in other example embodiments, the inner flange 1316 may not include the first set of notches 1318 and/or a second set of notches 1325 without departing from a broader scope of the present disclosure. For example, when installing a rimmed housing can 102 in a ceiling 602 fitted with the lathing ring 1300, both set of notches (1318, 1325) are optional. Further, in another example, if a retention system other than a pawl 504 is used, then, the inner flange 1316 of the lathing ring 1300 may include a thinner first set of notches 1318. Alternatively, the first set of notches 1318 may be configured according to the shape of the retention system or the first set of notches 1318 may be omitted.
Furthermore, even though the present disclosure describes the second set of notches 1325 formed in the inner flange 1316 of the lathing ring 1300 as being configured to impede the feet/flange portion of the flange clips 2502 or 3602 during installation to prevent over-insertion of the housing assembly, one of ordinary skill in the art can understand and appreciate that in other example embodiments, the second set of notches 1325 are optional even when the flange clips 2502 or 3602 are used. However, when present, the second set of notches 1325 assist in guiding the installation of the recessed housing can such that the recessed housing can in installed in a specific position as desired in some lighting applications, for example, in wall wash lighting applications.
As illustrated in FIGS. 13 and 14, the lathing ring 1300 may include one or more tab apertures 1308 disposed on the collar 1313 above the inner flange 1316. The tab apertures 1308 may extend from the inner surface 1313a of the collar 1313 through the outer surface 1313b of the collar 1313. Further, the collar 1313 may include guide rails 1309 disposed on either side of each tab aperture 1308. The guide rails 1309 may be configured to guide a coupling portion 1509 of a fold-over tab 1502 (shown in FIG. 15) into a groove 1306 formed between the guide rails 1309 in the collar 1313 of the lathing ring 1300 such that an aperture in the coupling portion 1509 of the fold-over tab 1502 may be axially aligned with the tab aperture 1308 of the collar 1313. As illustrated in FIG. 15, once the coupling portion 1509 of a fold-over tab 1502 is disposed in the groove 1306 formed between the guide rails 1309 and the aperture in the coupling portion 1509 of the fold-over tab 1502 is axially aligned with the tab aperture 1308 of the collar 1313, a fastener 1504 may be passed through the axially aligned apertures of the fold-over tab 1502 and the collar 1313 to couple the fold-over tab 1502 to the lathing ring 1300.
In certain example embodiments, multiple fold-over tabs 1502 may be coupled to the lathing ring 1300. In addition to the coupling portion 1509, the fold-over tabs 1502 may include a ceiling installation portion 1511 that comprises one or more installation slots 1506. The ceiling installation portion 1511 of the fold-over tabs 1502 may be flexible and may be configured to bend with respect to the coupling portion 1509. For example, the ceiling installation portion of the fold-over tabs 1502 may bend from a first position illustrated in FIGS. 15 and 16 where the ceiling installation portion 1511 and the coupling portion 1509 of the fold-over tabs 1502 are in the same plane to a second position illustrated in FIG. 18 where the ceiling installation portion 1511 and the coupling portion 1509 of the fold-over tabs 1502 are in different planes such that they form an angle between them. Even though FIG. 18 illustrates the ceiling installation portion 1511 of the fold-over tabs 1502 being bent such that it is substantially perpendicular to the coupling portion 1509, one of ordinary skill in the art can understand appreciate that in other example embodiments, the ceiling installation portion 1511 of the fold-over tabs 1502 may be bent more or less than shown in FIG. 18.
Referring to FIGS. 16-18, to couple the lathing ring 1300 to the ceiling 602, the fold-over tabs 1502 may be coupled to the lathing ring 1300 as described above and as illustrated in FIG. 15. Further, the lathing ring 1300 equipped with the fold-over tabs 1502 may be inserted through the aperture 606 of the ceiling 602 and the aperture 608 of the plaster ground plate 604 disposed on the ceiling 602. Even though the present disclosure describes installing the lathing ring 1300 in a ceiling 602 fitted with the plaster ground plate 604, one of ordinary skill in the art can understand and appreciate that in other example embodiments, installing the lathing ring in a ceiling without the plaster ground plate 604 is within the broader scope of the present disclosure. For example, in retrofit installations, the lathing ring 1300 may be installed in a ceiling that is not fitted with the plaster ground plate 604.
In particular, the lathing ring 1300 equipped with the fold-over tabs 1502 may be inserted through the apertures (606, 608) of the ceiling 602 and the plaster ground plate 604 till the outer flange 1301 of the lathing ring 1300 engages the bottom surface 602b of the ceiling 602. While inserting the lathing ring 1300 through the apertures (606, 608) of the ceiling 602 and the plaster ground plate 604, the ceiling installation portion 1511 of the fold-over tabs 1502 may be in the same plane as the coupling portion 1509 of the fold-over tabs 1502. That is, the ceiling installation portion 1509 of the fold-over tabs 1502 may be substantially perpendicular to the inner and/or outer flanges (1301, 1306) of the lathing ring 1300 as illustrated in FIG. 16. Responsive to inserting the lathing ring 1300 equipped with the fold-over tabs 1502 through the apertures (606, 608) of the ceiling 602 and the plaster ground plate 604, as illustrated in FIG. 18, the ceiling installation portion 1511 of the fold-over tabs 1502 may be bent to a second position where: (a) the ceiling installation portion 1511 engages the plaster ground plate 604 such that the plaster ground plate 604 and the ceiling is held between the ceiling installation portion 1511 of the fold-over tabs 1502 and the outer flange 1301 of the lathing ring 1300. In other words, the ceiling installation portion 1511 of the fold-over tabs 1502 may be bent such that they are substantially parallel with the ceiling 602. Then, as illustrated in FIG. 18, the lathing ring 1300 may be coupled to the ceiling 602 using fasteners 1702 that pass through the one or more mounting holes 1310 of the lathing ring's outer flange 1301, the ceiling 602, the mounting apertures 610 (shown in FIG. 6) of the plaster ground plate 604, and exit through one of the installation slots 1506 of the respective fold-over tabs 1506 that is axially aligned with the mounting holes 1310 of the lathing ring 1300.
In other example embodiments, the installation slots 1506 of the fold-over tabs 1502 may be sized such that installation slots 1506 allow a sheet-rock screw to thread into it and clamp the lathing ring 1300 to the ceiling 602 without the plaster ground plate 604. That is, the plaster ground plate 604 may be optional for the installation of the lathing ring 1300 in the ceiling 602.
Turning to FIGS. 19-20, responsive to installing the lathing ring 1300 in the ceiling 602, the rimmed housing can 102 with the pawl assembly 519 coupled thereto may be installed in the ceiling 602 that is fitted with the lathing ring 1300. In particular, initially, the rimmed housing can 102 with the pawl assembly 519 may be positioned below the ceiling 602 fitted with the lathing ring 1300 such that: (a) the rimmed housing can 102 is axially aligned with the aperture 606 defined by the ceiling 602, the opening 608 of the plaster ground plate 604, and the opening 1319 defined by the lathing ring 1300 that is installed in the ceiling 602; and (b) the pawls 504 that are coupled to the rimmed housing can 102 are aligned with the first set of notches 1318 formed in the inner flange 1316 of the lathing ring 1300. Responsively, the rimmed housing can 102 may be pushed up towards the ceiling 602 such that: (a) the side wall 106 of the rimmed housing can 102 passes through the aperture 606 and openings (608, 1319) defined by the ceiling 602, the plaster ground plate 604, and the lathing ring 1300, respectively; and (b) the pawls 504 coupled to the rimmed housing can 102 passes through the first set of notches 1318 formed in the in the inner flange 1316 of the lathing ring 1300, till the rim 108 of the rimmed housing can 102 engages and is impeded by the inner flange 1316 of the lathing ring 1300. Then, the pawls 504 of the pawl assemblies 519 coupled to the rimmed housing can 102 may be adjusted such that the pawls 504 engage the top surface 602a of the ceiling 602 (or the plaster ground plate 604) and clamps the ceiling 602 between the pawls 504 and the outer flange 1301 of the lathing ring 1300.
Further, as illustrated in FIGS. 21-22, the finishing section 1002 may be coupled to the rimmed housing can 102 by inserting the finishing section 1002 in the cavity 124 defined by the rimmed housing can 102 till the trim flange 2104 of the finishing section 1002 engages the bottom surface of the rim 108 of the rimmed housing can 102. The finishing section 1002 may be retained in the rimmed housing can 102 by friction using friction clips 1008 that engage the inner surface of the rimmed housing can's side wall 106 as illustrated in FIG. 23. The friction clips 1008 may be coupled to the top collar 1010 of the finishing section 1002 that extends radially outward from a top annular edge of a body 1006 of the finishing section 1002. The trim flange 2104 of the finishing section 1002 may be narrower than the trim flange 1004 of the finishing section 1002 illustrated in FIGS. 10-12
As illustrated in FIGS. 19-23, the width of both the rim 108 of the rimmed housing can 102 and the trim flange 2104 of the finishing section 1002 are configured such that they fit within the annular collar 1313 of the lathing ring 1300 to provide a flangeless appearance to the finishing section 1002, i.e., once plaster is applied to the bottom surface of the lathing ring 1300, e.g., on the outer flange 1301 and collar 1313 of the lathing ring 1300, and a portion of the trim flange 1004 as illustrated in FIG. 22B.
In certain example embodiments, the lathing ring 1300 may be fabricated using die cast aluminum. However, in other exemplary embodiments, any suitable material known to persons having ordinary skill in the art, such as sheet metal or a polymer material, is used to fabricate the lathing ring 1300. Further, in some example embodiments, the width of the rim 108 of the rimmed housing can 102 illustrated in FIGS. 19-23 may be smaller than the width of the rim 108 of the rimmed housing can 102 illustrated in FIGS. 1-11. In other example embodiments, the width of the rim 108 of the rimmed housing can 102 illustrated in FIGS. 19-23 may be substantially similar to the width of the rim 108 of the rimmed housing can 102 illustrated in FIGS. 1-11.
Even though the example embodiments of FIGS. 1-23 illustrate recessed luminaires that have a rimmed housing can 102, one of ordinary skill in the art can understand and appreciate that in other example embodiments, any other appropriate housing cans may be used without departing from the broader scope of the present disclosure. For example, the recessed luminaires may have a rimless housing can, i.e., a housing can without the integral rim 108 as illustrated in FIGS. 24-38. The installation of a recessed luminaire with a rimless housing can will be described in greater detail below in association with FIGS. 24-38.

Referring to FIGS. 24-35, the housing assembly 2700 of the recessed luminaire may include a rimless housing can 2400 and one or more one or more flange clips 2502. As in the rimmed housing can 102, the rimless housing can 2400 may include a substantially cylindrical side wall 2402 that extends from the top annular edge 2497 to the bottom annular edge 2406 and defines a cavity 124. Further, as in the rimmed housing can 2402, the side wall 106 of the rimless housing can 2400 may include one or more mounting assembly openings 110 to receive a respective mounting assembly, such as the pawl assembly 519. The side wall 2402 of the rimless housing can 2400 may also include one or more coupling apertures 119 that are disposed around each mounting assembly opening 110 for coupling the pawl assembly 519 to the rimless housing can 2400 using appropriate fasteners, such as screws, rivets, etc. Furthermore, the rimless housing can 2400 may include one or more flange notches 2408 that are formed in the side wall 2402 at the bottom annular edge 2406 of the rimless housing can 2400. Additionally, the side wall 2402 of the rimless housing can 2400 may include a flange aperture 2410 that is disposed above and adjacent each flange notch 2408.
Similar to rimmed housing can 102, the rimless housing can 2400 may include a top surface 2404 that extends radially inward from a top edge 2497 of the side wall 106 towards the cavity 124. The top surface 2404 may define a heat sink opening 202 to receive a heat sink assembly 3802 (shown in FIG. 38) therethough. The heat sink assembly 3802 may be configured to transfer heat away from the light module 3804 that is disposed in the cavity 124 formed by the side wall 106 of the rimless housing can 2400 and coupled to the heat sink assembly 3802. The heat sink assembly 3802 and/or the light module 3804 may be coupled adjacent the top surface 2404 of the rimless housing can 2400 using fasteners that are passed through the coupling apertures 204 disposed on the top surface 2404 of the rimless housing can 2400.
In other words, the rimless housing can 2400 may be substantially similar to the rimmed housing can 102 of FIGS. 1-23 except that the rimless housing can 2400 does not include a rim 108 as in the rimmed housing can 102. Instead, the rimless housing can 2400 includes flange notches 2408 and flange apertures 2410 that are configured to removably couple one or more flange clips 2502 to the rimless housing can 2400.
As illustrated in FIGS. 25-26, a flange clip 2502 may include an angled middle portion 2501, a coupling portion 2504 disposed on one end of the angled middle portion 2501, and a flange 2510 disposed on the opposite end of the angled middle portion 2501. The angled middle portion 2501 may include a first leg 2506 and a second leg 2508 that are arranged such that they define an obtuse angle. The coupling portion 2504 disposed adjacent the first leg 2506 may include a coupling aperture 2514. Further, the flange 2510 disposed adjacent the second leg 2508 of the angled middle portion 2501 may include a perforation 2512 formed therein that allows a portion 2604 of the flange 2510 to be detached from the flange clip 2502. An installer may detach the portion 2604 of the flange 2510 when a flange clip with a narrower flange 2602 is required.
Even though FIGS. 25-26 illustrate a single flange clip 2502 having a wide flange 2510 with perforations 2512 that allow a portion of the wide flange 2510 to be detached along the perforations 2512 for reducing the width of the flange (narrow flange 2602), one of ordinary skill in the art can understand and appreciate that in other example embodiments, two separate flange clips, one having a wide flange and other having a narrow flange, may be provided without departing from a broader scope of the present disclosure.
Referring to FIG. 27, the flange clips 2502 may be removably coupled to the rimless housing can 2400 using fasteners 2702, such as rivets, screws, etc. In particular, to removably couple a flange clip 2502 to the rimless housing can 2400, the flange clip 2502 may be positioned such that: (a) the coupling portion 2504 of the flange clip 2502 engages the inner surface of the rimless housing can's side wall 2402, (b) the coupling aperture 2514 in the coupling portion 2504 of the flange clip 2502 is aligned with the flange aperture 2410 of the rimless housing can's side wall 2402, (c) the angled middle portion 2501 of the flange clip 2502 extends out from the side wall 2402 of the rimless housing can 2400 through the corresponding flange notch 2408 on the side wall 2402 of rimless housing can 2400, and (d) the flange 2510 of the flange clip 2502 is flush with and extends radially out from the bottom annular edge 2406 of the rimless housing can 2400. Then, a fastener 2702 may be passed through the aligned coupling aperture 2514 and flange aperture 2410 of the flange clip 2502 and the rimless housing can 2402, respectively, to form the housing assembly 2700. Similarly, other flange clips 2502 may be removably coupled to the rimless housing can 2400 as illustrated in FIG. 27.
As illustrated in FIGS. 28-32, once the housing assembly 2700 is configured, the housing assembly 2700 may be installed in a ceiling 602 fitted with a lathing ring 1300. The lathing ring 1300 and the installation of the lathing ring 1300 in the ceiling 602 have been described above in greater detail in association with FIGS. 13-18 and will not be repeated herein for sake of brevity. To install the housing assembly 2700 in the ceiling 602 that is fitted with the lathing ring 1300, initially, a portion 2604 of the flange 2510 may be detached from each flange clip 2502. Then, the housing assembly 2700 with the pawl assemblies 519 may be positioned below the ceiling 602 fitted with the lathing ring 1300 such that: (a) the rimless housing can 2400 is axially aligned with the aperture 606 defined by the ceiling 602, the opening 608 of the plaster ground plate 604, and the opening 1319 defined by the lathing ring 1300 that is installed in the ceiling 602; (b) the pawls 504 that are coupled to the rimless housing can 2402 are aligned with the first set of notches 1318 formed in the inner flange 1316 of the lathing ring 1300; and (c) the flanges 2602 of the flange clips 2502 that are coupled to the rimless housing can 2402 are aligned with the second set of notches 1325 formed in the inner flange 1316 of the lathing ring 1300. As illustrated in FIG. 14, each of the second set of notches 1325 may include: (a) a flange receiving notch 1397 that is formed on a bottom surface of the inner flange 1316 of the lathing ring 1300, and (b) a pass through notch 1399 that is formed in the flange receiving notch 1397. The pass through notch 1399 may be deeper than the flange receiving notch 1397 and may extend from the flange receiving notch 1397 to a top surface of the lathing ring's inner flange 1316.
Once the housing assembly 2700 is positioned below the ceiling 602 fitted with the lathing ring 1300 as described above, the rimless housing can 2400 may be pushed up towards the ceiling 602 such that: (a) the side wall 2402 of the rimless housing can 2400 passes through the aperture 606 and openings (608, 1319) defined by the ceiling 602, the plaster ground plate 604, and the lathing ring 1300, respectively; (b) the pawls 504 coupled to the rimless housing can 2400 passes through the first set of notches 1318 formed in the in the inner flange 1316 of the lathing ring 1300; (c) a portion of the fasteners 2702 that project out from the side wall 2402 of the rimless housing can 2400 (e.g., screw head) passes through the respective pass through notches 1399 of the second set of notches 1325; and (d) the flange 2602 of the flange clips 2502 are received in the respective flange receiving notches 1397 of the second set of notches 1325 in the lathing ring 1300, as illustrated in FIG. 32. An installer may continue pushing the housing assembly 2400 through the aperture 606 and openings (608, 1319) defined by the ceiling 602, the plaster ground plate 604, and the lathing ring 1300, respectively, till the flanges 2602 of the flange clips 2502 that are coupled the rimless housing can 102 engage and are impeded by the inner flange 1316 of the lathing ring 1300. Responsively, the pawls 504 of the pawl assemblies 519 coupled to the rimless housing can 2400 may be adjusted such that the pawls 504 engage the top surface 602a of the ceiling 602 (or plaster ground plate) and clamps the ceiling 602 between the pawls 504 and the outer flange 1301 of the lathing ring 1300.
After installing the housing assembly 2700 in the ceiling 602 that is fitted with the lathing ring 1300, as illustrated in FIGS. 33-35, the finishing section 1002 may be coupled to the rimless housing can 2400 by inserting the finishing section 1002 in the cavity 124 defined by the rimless housing can 102 till the trim flange 2104 of the finishing section 1002 engages a bottom surface of the flanges 2602 of the flange clips 2502 that are coupled to the rimless housing can 2400. The finishing section 1002 may be retained in the rimless housing can 2400 by friction using friction clips 1008 that engage the inner surface of the rimmed housing can's side wall 106 as illustrated in FIGS. 33 and 35. The friction clips 1008 may be coupled to the top collar 1010 of the finishing section 1002 that extends radially outward from a top annular edge of a body 1006 of the finishing section 1002.
Even though FIGS. 24-35 illustrate flange clips 2502 that are coupled to the rimless housing can 2400 using fasteners 2702, one of ordinary skill in the art can understand and appreciate that in other example embodiments, flange clips that can be coupled to the housing can using any other appropriate coupling mechanism are within the broader scope of the present disclosure. For example, FIGS. 36-38 illustrate flange clips 3602 that use a snap mechanism for coupling to the rimless housing can.
Referring to FIGS. 36-38, the rimless housing can 3600 illustrated in FIGS. 36-38 may be substantially similar to the rimless housing can 2400 illustrated in FIGS. 24-35 except that the rimless housing can 3600 illustrated in FIGS. 36-38 may have snap slots 3606 in addition to the to the flange notch 3608 and the flange aperture 3610. Accordingly, the description of the rimless housing can will not be repeated herein for the sake of brevity. The snap slots 3606, the flange notches 3608, and the flange apertures 3610 of the rimless housing can 3600 may be configured to couple one or more snap fit flange clips 3602 to the rimless housing can 3600. In particular, each snap fit flange clip 3602 may include a middle portion 3616 comprising a hole 3614, a snap portion 3622 that comprises a snap feature 3612 disposed on one end of the middle portion 3616, and a feet portion 3619 comprising a flange 3618 disposed on an opposite end of the middle portion 3616.
As illustrated in FIGS. 37 and 38, the snap fit flange clips 3602 may be coupled to the rimless housing can 3600 by snap fit mechanism. In particular, to couple a snap fit flange clip 3602 to the rimless housing can 3600, the snap feature 3612 of the snap fit flange clip 3602 may be snapped into the snap slot 3606 of the rimless housing can 3600 such that: (a) a portion of the snap feature 3612 protrudes out from the side wall 3604 of the rimless housing can 3600 through the snap slot 3606 of the rimless housing can 3600, (b) the middle portion 3616 of the snap fit flange clip 3602 engages the inner surface of the rimless housing can's side wall 3604, (c) the hole 3614 of the middle portion 3616 of the snap fit flange clip 3602 is aligned with the flange aperture 3610 of the rimless housing can 3600, (d) the feet portion 3619 of the snap fit flange clip 3602 extends out from the side wall 3604 of the rimless housing can 3600 through the corresponding flange notch 3608 on the side wall 3604 of rimless housing can 3600, and (e) the flange 3618 of the snap fit flange clip 3602 is flush with and extends radially out from the bottom annular edge of the rimless housing can 3600. Similarly, other snap fit flange clips 3602 may be snapped to the rimless housing can 2400 as illustrated in FIG. 37.
The hole 3614 in the middle portion 3616 of the snap fit flange clip 3602 that is aligned with the flange aperture 3610 of the rimless housing can 3600 during installation may be provided as an alternate or additional coupling mechanism for coupling the snap fit flange clip 3602 to the rimless housing can 3600 using fasteners.

The installation of the rimless housing can 3600 fitted with the snap fit flange clips 3602 in the ceiling 602, and the installation of the finishing section 1002 in the rimless housing can 3600 may be substantially similar to the installation of the rimless housing can 2400 fitted with the flange clips 2502 in the ceiling 602, and the installation of the finishing section 1002 in the rimless housing can 2400, respectively, which is described above in association with FIGS. 24-35. Accordingly, the description regarding the installation of the rimless housing can 3600 fitted with the snap fit flange clips 3602 in the ceiling 602, and the installation of the finishing section 1002 in the rimless housing can 3600 will not repeated herein for the sake of brevity.
Even though FIGS. 13-38 illustrate a lathing ring that is coupled to a ceiling using fold-over tabs, one of ordinary skill in the art can understand and appreciate that in other example embodiments, recessed luminaires with lathing rings that can be coupled to the housing instead of the ceiling may be used without departing from a broader scope of the present disclosure. For example, FIGS. 39-46 illustrate a snap fit lathing ring that can be coupled to a housing instead of the ceiling 602. The snap fit lathing ring can be used in new constructions and/or old constructions independent of the ceiling thickness. That is, the same snap fit lathing ring can be used in different ceiling installations despite the different thicknesses of the ceiling since the installation of the snap fit lathing ring is not dependent on the ceiling.

Referring to FIGS. 39-44, the snap fit lathing ring 3900 may include a substantially annular inner wall 3908 that defines an annular opening 3920 and a substantially annular outer wall 3906 that is disposed outside the inner wall 3908 and partially surrounds the inner wall 3908. Further, the inner wall 3908 and the outer wall 3906 may define an annular groove 3916 disposed there between. Both the inner wall 3908 and the outer wall 3906 may include multiple wall sections that are detached from each other by spaces 3995 and 3999, respectively. Furthermore, the snap fit lathing ring 3900 may include one or more snap tabs 3910 that are disposed in the spaces 3995 formed in between the different wall sections of the inner wall 3908. Each snap tab 3910 may include a planar portion 3911 that comprises a coupling aperture 3912, and an angled flange 3921 that extends towards the outer wall 3906 at an angle from the planar portion 3911. Further, the snap fit lathing ring 3900 may include an outer flange 3901 that extends radially outward from the outer wall 3906, and an inner flange 3918 that extends radially inward towards the opening 3920 from the inner wall 3908.
The outer flange 3901 of the snap fit lathing ring 3900 may include a plurality of perforated openings 3902 that are formed circumferentially around the outer flange 3901 and extend through the thickness of the outer flange 3901. The perforated openings 3902 facilitate plastering on the outer flange 3901 since these perforated openings 3902 provide an area for the plaster to adhere itself. Additionally, the outer flange 3901 may include one or more mounting holes 3904 formed around and through the outer flange 3901. The one or more mounting holes 3904 may be configured to receive fasteners (not shown) therethrough to couple the lathing ring 3900 to the housing 4100 using fold-over tabs 4504 (shown in FIGS. 45 and 46. Furthermore, the snap fit lathing ring 3900 may include one or more notches 3991 and ramped surfaces 3993 formed in the inner flange 3918.
As illustrated in FIGS. 41 and 42, the housing 4100 may include a substantially cylindrical side wall 4102 that defines a cavity 4190, an upper collar 4104 that extends radially outward from a top edge of the side wall 4102, one or more mounting arms 4106 extending from the upper collar 4104 for coupling mounting features, such as adjustable hanger brackets 4302 (shown in FIG. 43) to the housing 4100, and a support arm 4115 extending radially outward from the upper collar 4104. Further, the housing 4100 may include an inner flange 4108 that is disposed adjacent a bottom edge of the side wall 4012 and extends radially inward into the cavity 4190 from an inner surface of the side wall 4102. The inner flange 4108 may include notches 4110 formed therein to engage the snap tabs 3910 of the snap fit lathing ring 3900 to couple the snap fit lathing ring 3900 to the housing 4100 as will be described in greater detail below in association with FIGS. 43 and 44. The portion of the housing side wall 4102 that extends between the inner flange 4108 and the bottom edge 4101 of the housing side wall 4102 may be referred to as a lip 4202.
Referring to FIGS. 43 and 44, the snap fit lathing ring 3900 may be coupled to the housing 4100 by positioning the snap fit lathing ring 3900 below the housing 4100 such that the lip 4202 of the housing 4100 is aligned with the annular groove 3916 of the snap fit lathing ring 3900. Then, the snap fit lathing ring 3900 may be pushed up towards the housing 4100 such that: (a) lip 4202 of the housing 4100 sits in the groove 3916 defined between the inner wall 3908 and the outer wall 3906 of the snap fit lathing ring 3900, (b) the outer wall of the snap fit lathing ring 3900 engages an external surface of the housing side wall 4102, (c) the inner wall 3908 of the snap fit lathing ring 3900 engages and is impeded by the housing's inner flange 4108, and (d) snap tabs 3910 of the snap fit lathing ring 3900 snaps into the notches 4110 formed in the inner flange 4108 of the housing 4100. In particular, the angled flange 3921 of the snap tabs 3910 engage the notch surface 4110 of the housing's inner flange 4108 to couple the snap fit lathing ring 3900 to the housing 4100.
Even though FIGS. 43 and 44 illustrate coupling a snap fit lathing ring 3900 to the housing 4100 by snapping the snap tabs 3910 of the snap fit lathing ring 3900 into the notches 4110 formed in the inner flange 4108 of the housing 4100, in other example embodiments, the snap fit lathing ring 3900 may be coupled to the housing 4100 using fold-over tabs 4504 in addition to or instead of snapping the snap tabs 3910 into the notches 4110 formed in the inner flange 4108 of the housing 4100. For example, as illustrated in FIGS. 45 and 46, one or more fold-over tabs 4505 may be coupled to the snap tabs 3910 of the snap fit lathing ring 3900 using fasteners 4502, such as screws or rivets. In particular, a coupling portion 4590 of the fold-over tabs 4504 may include an aperture that may be aligned with the coupling aperture 3912 formed in the snap tabs 3910. Further, fasteners 4502 may be passed through the aligned apertures of the fold-over tabs 4504 and the snap tabs 3910 of the snap fit lathing ring 3900 to couple the fold-over tabs 4504 to the snap fit lathing ring 3900. The fold-over tabs 4504 may include an installation portion 4591 that includes a plurality of installation slots 4593 for coupling to the housing 4100.
As illustrated in FIG. 46, once the snap fit lathing ring 3900 is coupled to the housing 4100 using the snap tabs 3910 as described above, the installation portion 4591 of the fold-over tabs 4504 that are coupled to the snap fit lathing ring 3900 may be folded such that it engages and is impeded by the upper collar 4104 of the housing 4100. In some embodiments, the additional apertures 4203 disposed on the installation portion 4591 of the fold-over tabs 4504 may be aligned with corresponding apertures 4191 on the upper collar 4104 of the housing 4100. The fold-over tabs 4504 may be provided as an additional or alternative coupling mechanism for coupling the snap fit lathing ring 3900 to the housing 4100.
