Description

Recessed lighting with independent adjustment between lighting and driver components Ming equipment

This application claims the benefit of U.S. Design Patent Application No. 29/591,403, filed January 19, 2017, the entire contents of which are hereby incorporated by reference.

The invention discloses a built-in lighting fixture, especially the built-in lighting fixture with an independent adjustment function between a lighting component and a driving component.

Walking into any room or store, one thing most people take for granted is lighting. As long as the lighting is adequate and not distracting, people will focus on the elements in the room or the products on display. However, this can change quickly (for the worse) if there are lighting fixtures that don't work, flickering lighting, lighting that emits a high pitch, and/or lighting that looks too bright or too dark for the environment. In essence, most lighting is an understated decorative component that performs its function as intended without drawing (obviously) attention to itself.

Manufacturers of lighting products, including recessed lighting products, meet customer needs by creating lighting products that are often aesthetically pleasing, cost-effective, and comply with building/electrical codes. Manufacturers devote most of their efforts to creating different Lighting design and features. This includes providing lighting fixtures and/or shades in different shapes and colors, different types of lighting (e.g. track lighting, recessed lighting, pendant lighting, etc.), and different types of Light source (eg, incandescent, compact fluorescent, light emitting diode ("LED"), etc.).

Lighting fixtures designed for repair or replacement take little effort. From the customer's point of view, these features will not be seen after installation and therefore not understood. Furthermore, the installation of lighting fixtures in new construction (or gut-rehab construction) is usually not a problem because the lighting fixtures are installed before the plasterboard (or plaster) is hung. This enables an electrician to easily attach lighting fixtures to wall studs or ceiling studs and connect/route electrical wiring. Therefore, manufacturers provide the minimum features required to secure lighting fixtures to walls or ceilings.

Unfortunately, manufacturers' lack of attention to this often makes it difficult to repair or update lighting fixtures after initial installation. For example, many lighting fixtures are powered by drivers, ballasts, or transformers that control the power (eg, current or voltage) that provides the lighting. Like many electrical devices, drives, ballasts and transformers may fail after prolonged use or due to internal defects. Drivers, ballasts and transformers can also fail if connected to inappropriate lighting or dimmers, or after a power surge. Non-working drivers, ballasts or transformers result in non-functional lighting and customer confusion. In many lighting fixtures, the driver, ballast or transformer is placed away from the lamp to reduce heat buildup. This means that it is often difficult for an electrician to replace a driver, ballast or transformer when the only point of access is through an opening in the ceiling of the lighting assembly. In some cases, a large portion of the ceiling or wall must be removed to allow access to) drivers, ballasts or transformers, or replace the entire lighting fixture. Cutting the ceiling or walls adds cost to the project because the client must seal off the opening and repaint it.

In another example, an increasing number of clients are undertaking small to mid-sized home improvement projects. These items can include lighting changes like adding or replacing dimmers, and replacing incandescent or compact fluorescent bulbs with LED lights. To save costs, homeowners and/or electricians attempt to re-use installed electrical boxes and simply replace light elements/assemblies and drivers, ballasts or transformers. However, as mentioned above, the drivers are often difficult to access, making it more difficult to replace the lighting. This can cause some clients to forego lighting replacement projects entirely due to the additional cost and effort.

The present disclosure provides a new and innovative recessed lighting fixture device with relatively easy access to drivers, ballasts or transformers. An exemplary recessed lighting fixture includes a lighting fixture housing configured to include a driver assembly housing and a lighting assembly housing. Each housing may comprise a sheet metal box with one open side. The drive assembly housing is configured to contain at least one of a driver, a ballast and a transformer. The lighting assembly housing is configured to contain lighting sockets and/or lighting sources, such as LED lights, halogen lights, incandescent bulbs or integrated fluorescent bulbs. The lighting assembly housing, the driving assembly housing and the open sides of the driving assembly housing are configured to face the same direction. After installation in the ceiling, each open side is configured to face the inside of the ceiling where the lighting assembly housing is positioned to face the opening in the ceiling for mounting lighting fixtures or lighting sources.

The lighting assembly housing is movably connected to the drive assembly housing such that the lighting assembly housing can move or slide vertically relative to the drive assembly housing (and lighting fixture assembly). this vertical The movement enables the lighting assembly housing to be pulled down through the opening in the ceiling. The ability to move down allows an electrician to more easily access the lighting fixture and associated electrical wiring for repair and/or replacement.

The lighting assembly housing and the drive assembly housing are also configured to move horizontally together within the lighting fixture assembly. This allows the drive assembly housing to slide over the opening in the ceiling for easy maintenance and/or replacement. This also enables the lighting fixture to be easily connected or reconnected to the driver, ballast or transformer in the driver assembly housing.

In an exemplary embodiment, a recessed lighting fixture device includes a lighting fixture housing including a first box having an open side and a closed side. The lighting fixture housing includes a first post connected to the interior surface of one of the closed sides, and a second post connected to the interior surface of one of the closed sides.

FIG. 1 shows a perspective view of a recessed lighting fixture 100 including a lighting fixture housing 102 according to an exemplary embodiment of the present disclosure. The exemplary lighting fixture housing 102 includes a rectangular box having an open side and five closed sides. The open side is configured to face the ceiling and/or the interior surface of the wall. Thus, the view of the recessed lighting fixture 100 of FIG. 1 is an upside-down view when the lighting fixture housing 102 is mounted on top of a ceiling. Lighting fixture housing 102 has a width between 4 inches and 18 inches, preferably between 8 inches and 12 inches. Furthermore, the lighting fixture housing 102 has a length between 6 inches and 44 inches, preferably between 24 inches and 30 inches. Additionally, the lighting fixture housing 102 has a depth of between 3 inches and 8 inches, preferably between 4 inches and 6 inches.

Exemplary lighting fixture housing 102 includes poles 104a, 104b, 106a, and 106b on opposite faces facing the closed side. The poles 104 and 106 are configured to face the interior of the lighting fixture housing 102 . In some embodiments, the rods 104 and 106 may be connected to the lighting fixture housing 102 by screws or rivets. In other examples, the rods 104 and 106 may be welded or chemically joined to the lighting fixture housing 102 . Exemplary poles 104 and 106 are configured with a circular or oval profile. In other examples, the pole may have a rectangular profile. Additionally, in some embodiments, the rods 104 and 106 may be coated and/or impregnated with an anti-friction material such as oil or chemicals.

As shown in FIG. 1 , the poles 104 and 106 are located on closed, opposing sides of the lighting fixture housing 102 . For example, pole 104a is located opposite pole 104b. The poles 104 and 106 are located near the open side of the lighting fixture housing 102 . In some embodiments, the rods 104 and 106 may be less than 2 inches from the closed side. In other embodiments, the poles 104 and 106 may be positioned vertically on the lighting fixture housing 102 inside the middle of the closed side. Although FIG. 1 shows a pair of opposing poles 104 and 106 , in other embodiments, the lighting fixture housing 102 may include only one pole 104 and one pole 106 . Alternatively, each side of the lighting fixture housing 102 may include a plurality of poles 104 and 106 .

The embedded lighting fixture 100 in FIG. 1 also includes a driving unit housing 110 and a lighting unit housing 120 . Each of housings 110 and 120 is configured to fit within lighting fixture housing 102 such that the open sides of housings 110 and 120 are oriented and/or aligned with the open sides of lighting fixture housing 102 . Drive assembly housing 110 has a width between 4 inches and 18 inches, preferably between 8 inches and 12 inches. Additionally, the drive assembly housing 110 has a length between 2 inches and 12 inches, preferably between 6 and 10 inches. Lighting assembly housing 120 has a width between 4 inches and 18 inches, preferably between 8 inches and 12 inches. Additionally, the lighting assembly housing 110 has a length between 2 inches and 24 inches, preferably between 6 inches and 12 inches. Additionally, housings 110 and 120 have a depth between 3 inches and 8 inches, preferably between 4 inches and 6 inches.

As discussed further in connection with FIGS. 1-9 , housings 110 and 120 are configured to move relative to stationary lighting fixture housing 102 along horizontal axis 103a. Additionally, the lighting assembly housing 120 is configured to move relative to the housings 102 and 110 along the vertical axis 103b. As one can appreciate, references herein to horizontal and vertical directions/movements refer to the lighting fixture housing 102 and are independent of how the housing 102 is mounted/racked.

As illustrated in FIG. 1 , driver assembly housing 110 and lighting assembly housing 120 have a width slightly smaller (eg, 1/8 or 1/16 inch) than lighting fixture housing 102 so that housings 110 and 120 can It fits inside the housing 102 with enough space to be able to slide along the horizontal axis 103a. In addition, it should be understood that the driving unit housing 110 and the lighting unit housing 120 have lengths shorter than the lighting fixture housing 102 so that the housings 110 and 120 can slide within the housing 102 . Preferably, if combined with Fig. 7 to Fig. 9 to further As further discussed, the dimensions of the housings 110 and 120 are relative to the dimensions of the housing 102 to provide sufficient space for the drive assembly housing 110 to move along the horizontal axis 103a to match the lighting assembly housing 120 in the ceiling. The manufactured openings are aligned. Additionally, housings 110 and 120 have a depth equal to or slightly less (eg, 1/2 to 1/16 inches) than lighting fixture housing 102 .

As shown in FIG. 1, the drive assembly housing 110 includes slots 112a and 112b. Exemplary slots 112a and 112b are extended windows or sheet metal cutouts along opposing faces of the closed side of drive assembly housing 110 . Slots 112a and 112b are centered along respective sides and extend along approximately 75% of the length of the sides of drive assembly housing 110 . In other examples, the slots 112a and 112b may have a smaller length depending on the length of the drive assembly housing 110 and the lighting fixture housing 102 and/or the amount of space for horizontal movement. Slots 112a and 112b are configured to enable passage of respective rods 104a and 104b. Where only one rod 104a is provided, the drive assembly housing 110 includes only the slot 112a.

Slots 112a and 112b in combination with corresponding rods 104a and 104b enable drive assembly housing 110 to slide horizontally within lighting fixture housing 102 while being movably secured to lighting fixture housing 102 . For example, slots 112a and 112b in combination with posts 104a and 104b prevent drive assembly housing 110 from falling vertically from lighting fixture housing 102 when installed.

In some embodiments, the drive assembly housing 110 may include one or more connectors, such as the connectors 114a and 114b shown in FIG. 1 . Exemplary connectors 114 a and 114 b are configured to mechanically couple to corresponding slots 122 a and 122 b of drive assembly housing 110 to lighting assembly housing 120 . The connectors 114a and 114b may include screws and lock nuts, screw nuts, hex nuts, flange nuts, castle nuts or winged nuts. nut) at least one. For example, connectors 114a and 114b may include screws that pass through respective slots 122a and 122b and nuts that close off the ends of the screws, thereby securing housings 110 and 120 together. Connector 114a and 114b may be threaded into holes in drive assembly housing 110 and/or may be attached to drive assembly housing 110 via screws, rivets, solder, welding, and/or chemical fasteners. Although FIG. 1 shows two connectors 114a and 114b, it should be understood that other embodiments may include fewer connectors or additional connectors. Additionally, while FIG. 1 shows connectors 114a and 114b located near the open side of drive assembly housing 110 (e.g., one inch from the edge), in other embodiments, the connectors may be located in the middle of the sides of the drive assembly housing. or bottom.

The illustrated embodiment shows that the drive assembly housing 110 may also include a retaining ring 116 on the same closed side as the connectors 114a and 114b. Buckle 116 is configured to fit within a window of drive assembly housing 110 to enable wires from lighting assembly housing 120 to pass through. The snap ring 116 is aligned with the slot 124 on the light assembly housing 120 .

Exemplary lighting assembly housing 120 includes slots 122a and 122b for connecting to connectors 114a and 114b , and slot 124 for contacting and/or aligning with snap ring 116 . Exemplary slots 122a and 122b are configured to enable passage of connectors 114a and 114b, respectively. In some cases, connectors 114a and 114b may contact exterior and interior portions of the sides of housing 120 adjacent slots 122a and 122b so as to reduce free movement of connectors 114a and 114b within slots 122a and 122b. This enables, for example, the lighting assembly housing 120 to remain in place along the vertical axis 103b until moved by an electrician. In some cases, connectors 114a and 114b may be manually locked by an electrician to prevent vertical movement of the lighting assembly housing relative to the drive assembly housing. For example, the connectors 114a and 114b may include thumb nuts that are locked near the sides of the lighting assembly housing 120 adjacent the corresponding slots 122 .

Additionally or alternatively, clasp 116 may be configured to reduce free vertical movement between housings 110 and 20 . For example, the buckle 116 that contacts the inner edge of the slot 124 may comprise a rubber or plastic material. The contact between the retaining ring 116 and the edge of the slot 124 creates friction to prevent the lighting assembly housing from The body 120 is free to move along the vertical axis 103b. Friction can be overcome by an electrician manually moving housing 120 . This configuration enables the housing 120 to be lowered or raised to a desired position for maintenance and/or installation. In other examples, contact between the buckle 116 and the edge of the slot 124 is minimal, allowing the housing 120 to move freely.

As shown in FIG. 1 , the slots 122 and 124 are parallel to each other and aligned along the vertical axis 103b. This alignment of the slots 122 and 124 enables the lighting assembly housing 120 to move or slide along the vertical axis 103b while the drive assembly housing 110 remains stationary. The length of the slots 122 and 124 defines how much the lighting assembly housing 120 can move along the vertical axis 103b, with shorter slots 122 and 124 corresponding to less movement. As noted above, the lighting assembly housing 120 is movable in the vertical axis 103b to allow an electrician to access the lighting assembly within the housing 120 and/or install lighting fixtures, lighting sources, and/or recessed lighting assemblies 150 . After pulling down the housing 120, the electrician can further more easily route the wires through the slot 124 and the buckle 116 from the lighting assembly housing 120 to the driver assembly housing. The rest position of the buckle 116 ensures that the wires do not move vertically at the boundary between the housings 110 and 120 and prevents the wires from being abraded or cut by the slot 124 .

The exemplary lighting assembly housing 120 of FIG. 1 also includes L-shaped or J-shaped slots 126a and 126b. Slots 126a and 126b are configured to receive rods 106a and 106b, respectively. Each of the slots 126a and 126b has a horizontal portion aligned with the horizontal axis 103a. The horizontal portions of the slots 126a and 126b enable the lighting assembly housing 120 to move or slide horizontally within the lighting fixture housing 102 . Slots 126a and 126b also include vertical portions aligned with vertical axis 103b. The vertical portions of the slots 126a and 126b allow the lighting assembly housing 120 to move or slide vertically relative to the driving assembly housing 110 .

The horizontal portions of slots 126a and 126b have substantially the same length as slots 112a and 112b. Having slots 112 and 126 of the same length enables housings 110 and 120 to have the same range of horizontal movement, which is important when assuming housings 110 and 120 are connected together. In addition, slot 126a and The length of the vertical portion of 126b is substantially the same as the length of slots 122a, 122b and 124. Slots 122 , 124 , and 126 having the same length enable lighting assembly housing 120 to slide or move vertically relative to both driver assembly housing 110 and lighting fixture housing 102 .

It should be appreciated that the location of the vertical portion of the L-shaped or J-shaped slot 126 places the intended opening in the ceiling or wall on the respective side of the lighting assembly housing 120 . In other words, an opening in the ceiling will be created and/or the recessed light fixture 100 will be positioned in alignment with the lighting assembly housing 120 so that the rod 106 is located within the vertical portion of the slot 126 (or near the vertical portion of the slot 126). part). As discussed further in connection with FIGS. 7-9, this enables the lighting assembly housing 120 to be pulled down through the opening in the ceiling. Otherwise, the closed portion of the ceiling would block the downward movement of the lighting assembly housing 120 as the housing 120 slides such that the rods 106 are positioned within the vertical portions of the corresponding slots 126 . Thus, the exemplary L-shaped or J-shaped slot 126 enables the lighting assembly housing 120 to move along the horizontal axis 103a when the rod 106 is positioned within the horizontal portion of the slot 126, and when the rod 106 is positioned within the horizontal portion of the slot 126. When within the vertical section, an exemplary L-shaped or J-shaped slot 126 enables movement of the lighting assembly housing 120 along the vertical axis 103b. The configuration of the rod 106 and slot 126 prevents the lighting assembly housing 120 from falling or moving downward when not positioned over the opening in the ceiling, and also prevents the lighting assembly housing 120 from falling horizontally when the housing 120 is pulled downward. move.

The exemplary lighting assembly housing 120 is configured to be mechanically and/or electrically connected to a lighting fixture or recessed lighting assembly 150 . The embedded lighting assembly 150 shown in FIG. 1 includes a heat sink 152 , a light emitting element 154 , a cup 156 , and a trim piece 158 . It should be understood that the design and appearance of the trim member 158 , lampshade 156 , light emitting element 154 , and heat sink 152 illustrate a lighting fixture for the recessed lighting fixture 100 . In other embodiments, the shape and/or design of the heat sink 152, the light emitting element 154, the lampshade 156, and the decoration may be different. For example, for a hanging lighting fixture, the lampshade 156 and trim 158 can be replaced with a hanger and light pole.

The heat sink 152 is configured to absorb and dissipate heat generated from the light emitting element 154 . The heat sink 152 may include a connector for electrically and/or mechanically connecting with the lighting assembly housing 120 . Light emitting element 154 may comprise any type of lamp or illumination source including, for example, LED lamps, halogen lamps, incandescent bulbs, or compact fluorescent lamps. Exemplary shades 156 include plastic and/or metal reflectors and/or deflectors. Depending on the desired lighting effect, the shade 156 may be configured to absorb light, reflect light, and/or reflect light of different colors. In some cases, the shade may include patterns or stripes to adjust light reflection/absorption. Exemplary trim 158 is configured to provide a decorative covering to an opening in a ceiling or wall. The trim 158 is configured, for example, to sit flush with the outside of the ceiling.

The exemplary recessed lighting fixture 100 of FIG. 1 also includes mounting bars 160a and 160b configured to connect to ceiling beams or wall columns. Mounting rods 160a and 160b are attached to the exterior surface of the lighting fixture housing 102 on opposite sides of the closed side. While FIG. 1 shows the mounting bars 160 positioned along the width of the housing 102 , in other examples, they may be positioned along the length of the housing 102 .

The exemplary mounting rod 160 may be telescoping such that its length can be adjusted. This telescoping feature enables the mounting rod 160 to be positioned to fit between adjacent ceiling beams or wall columns. Mounting rod 160 includes a bracket 162 at each end configured to contact a ceiling beam or wall post. Brackets 162 are attached at right angles so that the faces of the brackets contact the sides of the beams or studs. Brackets 162 may include tabs including holes or windows that guide nails into ceiling beam posts or wall posts.

FIG. 2 shows a side view of the recessed lighting fixture 100 of FIG. 1 according to an exemplary embodiment of the present disclosure. In this figure, the closed sides (from the viewer's point of view) of the housings 102, 110 and 120 are made transparent. As shown in FIG. 2, housings 110 and 120 slide all the way to the right (from the viewer's point of view) so that rod 104 is positioned at the end of slot 112 and rod 106 (not shown) is tied to slot 126. within the vertical portion of the . This positioning of the housings 110 and 120 enables the lighting assembly housing 120 to move upwards (relative to the viewer, but downwards in practical use within the ceiling) along the vertical axis 103b.

As shown in FIG. 2 , the diameter of the rod 104 is slightly smaller than the diameter of the slot 112 . This enables the rod 104 to pass through the slot 112 during manufacture and slide along the slot 112 during use. In a similar manner, the diameter of the rod 106 is slightly smaller than the diameter of the slot 126 .

FIG. 2 shows that the lighting assembly housing 120 includes a lighting receptacle 202 configured to connect to or otherwise receive or receive the connector 204 of the recessed lighting assembly 150 . In some examples, the connectors 204a and 204b can each provide power and ground connections to corresponding terminals within the lighting socket 202 . Additionally or alternatively, connectors 204a and 204b are configured to mechanically engage corresponding connectors within lighting socket 202 . Where only a mechanical connection is made, the wires run from the recessed lighting assembly 150 to the lighting receptacle 202 and through the buckle 116 to the driver 206 . Otherwise, if the connectors 204a and 204b provide an electrical connection to the lighting socket 202 , wires can pass from the lighting socket 202 through the buckle 116 to the driver 206 . It should be understood that many different types of electrical and/or mechanical connectors may be used to secure the recessed lighting assembly 150 to the lighting assembly housing 120 .

The example driver 206 is configured to regulate or control power to the light emitting elements 154 . Driver 206 may include any electrical driver, ballast, and/or transformer. In some examples, the driver 206 may match the AC power source to a specific DC voltage and/or regulate the voltage based on a pulse width modulation (PWM) signal received from a dimmer switch. Additionally or alternatively, the driver 206 can transmit control power to the light emitting element 154 via a PWM signal. Driver 206 receives power and ground from circuitry in the structure, which may be accessed through window 208 of driver assembly housing 110 .

As shown in FIG. 2 , the driver 206 is mechanically coupled to the closed side (opposite the open side) of the drive assembly housing 110 . The driver 206 is electrically connected (directly or indirectly) to the light emitting element 154 via at least one power line and ground line. The electrical wires are routed through the grommet 116 of the drive assembly housing 110 . The snap ring 116 is shown passing through the window of the drive assembly housing 110 and the slot 124 of the lighting assembly housing 120 . The positioning of the snap ring 116 prevents the wires from contacting the edges of the sheet metal of the housings 110 and 120 , particularly when the lighting assembly housing 120 is slid vertically relative to the driver assembly housing 110 . Thus, the grommet 116 prevents the wires from being frayed or spliced from the sharp sheet metal edges of the slot 124 of the housing 120 and the window of the housing 110 . Additionally, the ability to pull the lighting assembly housing 120 from the lighting fixture housing 102 provides an electrician with easier access to wiring from the housing 120 to the drive assembly housing 110 through the buckle 116 .

FIG. 3 shows a perspective view of the recessed lighting fixture 100 of FIGS. 1 and 2 with a recessed lighting assembly 150 connected to a lighting assembly housing 120 according to an exemplary embodiment of the present disclosure. Once installed, the lighting assembly housing 120 can be slid vertically back into the lighting fixture housing 102 so that the trim 158 contacts the exterior surface of the ceiling and/or wall, thereby covering the opening. Additionally, the lighting assembly housing 120 may slide slightly to the left to prevent the housing 120 from moving vertically after installation.

In some examples, the lighting fixture housing 102 may not be mounted flush with the inside of the ceiling. Instead, there may be a gap of several inches between the ceiling and housing 102 . In these cases, the vertical adjustment of the lighting assembly housing 120 enables an electrician to set the desired height to ensure that the trim is flush with the ceiling. The light assembly housing 120 may be held vertically via the snap ring 116 contacting the edge of the slot 124 and/or via the jam nut of the connector 122 .

FIG. 4 shows a cross-sectional perspective view of the recessed lighting fixture 100 of FIG. 3 according to an exemplary embodiment of the present disclosure. In addition, FIG. 5 shows that of FIG. 3 according to an exemplary embodiment of the present disclosure. Cross-sectional side view of recessed lighting fixture 100 . The cross-sections of FIGS. 4 and 5 are taken by effectively cutting the housings 102, 110 and 120 in half at the midpoint of their width.

4 and 5 show connections between the lighting socket 202 of the recessed lighting assembly 150 and the connectors 204a and 204b. Specifically, the example connectors 204a and 204b are configured to mate with corresponding openings or terminals of the lighting socket 202 . The connection takes place near the heat sink 152 . Figures 4 and 5 also show the lip of the trim 158 configured to contact the exterior surface of the ceiling or wall. The trim 158 covers the opening in the ceiling or wall, except for the rear side of the lighting assembly housing 120, heat sink 152, connector 204, and lampshade 156.

FIG. 6 shows a side view of the recessed lighting fixture 100 of FIG. 5 with the side of the lighting fixture housing 102 being opaque, according to an exemplary embodiment of the present disclosure. In the embodiment shown here, the rods 104b and 106b are shown to comprise screws provided through holes in the lighting fixture housing 102 . In particular, screws are provided through holes in the lighting fixture housing 102 and attached to the poles 104b and 106b. In some embodiments, the screws may be integrated with the rods 104b and 106b to form a unitary structure. Alternatively, the screws can be replaced with rivets.

In this example, the lighting assembly housing 120 is vertically raised (or lowered depending on installation and perception) from the lighting fixture housing 102 . Accordingly, the rod 106b is shown in the vertical portion of the L-shaped or J-shaped slot 126b. As noted above, the lighting assembly housing 120 can move vertically upon sliding of the rod 126b within the vertical portion of the slot 126b. As the rod 106b slides along the horizontal portion of the slot 126b, the lighting assembly housing 120 (in conjunction with the drive assembly housing 110 when connected) moves along the horizontal axis 103a while the rod 106 moves along the horizontal portion of the slot 106. Partially slide. In order to move horizontally, the lighting assembly housing 120 must be fully retracted into the lighting fixture housing 102 so that the rod 106b can slide within the horizontal portion of the slot 126b.

Examples of use of recessed lighting fixtures

FIGS. 7-9 show schematic diagrams of the housings 110 and 120 within the recessed lighting fixture 100 of FIGS. 1-6 moved for maintenance according to exemplary embodiments of the present disclosure. In these figures, the lighting fixture housing 102 is shown with a transparent closed side to show the position of the rods 104 and 106 within the respective slots 112 and 126 . Additionally, FIGS. 7-9 show the position of the recessed lighting fixture 100 relative to a ceiling 702 which is also shown as transparent. Thus, the views of Figures 7-9 provide a reversed view as compared to the perspective view of the recessed lighting fixture 100 when actually installed.

In the example shown in this embodiment, the ceiling 702 includes an opening 704 that is slightly larger than the open side of the lighting assembly housing 120 . In FIG. 7 , housings 110 and 120 are shown sliding to the left (from the viewer's perspective) so that at least a portion of drive assembly housing 110 can face opening 704 . In some cases, housings 110 and 120 can be slid as far left as possible to align the entire open side of drive assembly housing 110 with opening 704 . This enables, for example, an electrician to easily service and/or replace the driver 206 through the opening 704 . An electrician can also relatively easily route wires from the driver 206 , through the grommet 116 to the light assembly housing 120 .

In the position shown in FIG. 7, the rod 104 is located in the middle portion of the slot 112 or towards the right section, respectively. In addition, the rod 106 is located in the middle portion or in the rightward portion of the horizontal portion of the slot 126, respectively. The location of the rod 106 within the horizontal portion of the slot 126 prevents the lighting assembly housing from being pulled down (or otherwise moved), which could potentially damage the ceiling.

FIG. 7 also shows an example where the rod 106 includes a thumb nut that may be used to lock or prevent movement of the lighting assembly housing 120 . For example, an electrician can loosen the wing nut of rod 106 to slide housings 110 and 120 horizontally or housing 120 vertically. Then, when the housings 110 and 120 are in the desired position, the electrician can lock the wing nuts to prevent the The subsequent casings 110 and 120 move further. For example, when the rod 106 is midway within the vertical portion of the slot 126, an electrician can tighten the wing nut to set the desired vertical position of the lighting assembly housing.

Turning from Figure 7 to Figure 8, the wing nut is loosened from the rod 106, which allows the housings 110 and 120 to slide horizontally. Specifically, housings 110 and 120 move to the right within lighting fixture housing 102 along horizontal axis 103a. This sliding causes the drive assembly housing 110 to be covered by the ceiling 702b when the lighting assembly housing 120 is aligned with the opening 704 . Once the lighting assembly housing 120 is aligned with the opening 704 , the electrician can pull or move the housing 120 downwardly (shown upwardly in FIG. 9 ) to enable relatively easy installation of the recessed lighting assembly 150 . Alignment of the opening 704 is aided in part by the rod 106 contacting the intersection of the horizontal and vertical portions of the slot 126 . At this point, the rod 106 can slide vertically through the slot 126 .

FIG. 9 shows that when the driving unit housing 110 and the lighting fixture housing 102 remain stationary, the lighting unit housing 120 slides through the opening 704 along the vertical axis 103b. The rod 106 is shown sliding within the vertical portion of the slot 126 (via sliding relative to the slot 126 of the rod 106). The electrician can tighten the wing nut to lock the vertical position of the lighting assembly housing 120 . Furthermore, the position of the rod 106 within the vertical portion of the slot 126 prevents the housings 110 and 120 from moving horizontally.

Also, as shown in FIG. 9, during the vertical sliding of the lighting assembly housing 120, the slots 122 slide along the connectors 114 such that the bottom ends of the slots 122 approach the connectors 114, respectively. Additionally, the bottom end of the slot 124 is proximate to the buckle 116 . The slots 122 and 124 , the connector 114 and the buckle 116 allow the lighting assembly housing 120 to move vertically relative to the driver assembly housing 110 through the opening 704 . After the repair or installation is complete, the electrician slides the lighting assembly housing 120 back into the lighting fixture housing 102 so that the trim 158 is flush with the ceiling 702 .

The length and shape of the slots may be similar to the slots 112 and 126 shown in FIGS. 1-9. This configuration enables the housings 110 and 120 to move horizontally within the lighting fixture housing 102 despite the inversion between the rods 104 and 106 and the slots 112 and 126 .

Additionally or alternatively, connector 114, buckle 116, and slots 122 and 124 may be reversed. In particular, connector 114 and buckle 116 may be included in light assembly housing 120 while slots 122 and 124 are included in drive assembly housing 110 . This configuration enables the light assembly housing 120 to move vertically relative to the drive assembly housing 110 despite the inversion between the connector 114 and the slot 122 .

In another embodiment, the housings 110 and 120 may not be connected together. In this alternative embodiment, the drive assembly housing 110 may not include the connector 114 and the lighting assembly housing 120 may not include the slot 122 . However, the drive assembly housing 110 may include a snap ring 116 and the lighting assembly housing 120 may include a slot 124 to enable wiring between the housings 110 and 120 .
