Description

Recessed lighting fixture with independent adjustment between lamp assembly and driver assembly

Priority declaration

This application claims the benefit of U.S. design patent application No. 29/591,403 filed on 2017, 1, 19, which is hereby incorporated by reference in its entirety.

Technical Field

The invention relates to a recessed lighting fixture with independent adjustment between a lamp assembly and a driver assembly.

Background

When walking into any room or store, most people will think that lighting is a matter of course. As long as the lighting is adequate and not distracting, one will focus on the components in the room or the product being displayed. However, if there are inoperative lighting fixtures, flashing lights, lights that emit high-pitched tones, and/or lights that appear to be too bright or too dark in a given environment, attention can change rapidly (worse). Essentially, most lighting is a low-profile trim component that performs its function as intended, without drawing (too much) attention to itself.

Manufacturers of lighting products, including embedded lighting products, meet customer needs by creating lighting products that are generally aesthetically pleasing, cost effective, and meet building/electrical specifications. To meet different customer tastes and decorative styles, manufacturers devote a great deal of effort to create different lighting designs and features. This includes providing illuminated ornaments and/or light cups of different shapes and colors, different types of lighting (e.g., track lighting, recessed lighting, ceiling lighting, etc.), and different types of illumination (e.g., incandescent lights, compact fluorescent lights, light emitting diodes ("LEDs"), etc.).

Little effort is expended in designing lighting fixtures for repair or replacement. From a customer perspective, these features would not be visible after installation and are therefore not favored. Furthermore, the installation of light fixtures in new construction (or historic building repair works) is generally not a problem because the light fixtures are installed before the drywall (or plaster) is hung. This enables electricians to easily attach lighting fixtures to walls or ceiling studs (stud) and make connections/wiring. Thus, manufacturers provide the minimum features required to secure a lighting fixture to a wall or ceiling.

Unfortunately, this lack of attention by manufacturers often results in lighting fixtures (lighting fixtures) that are difficult to repair or update after initial installation. For example, many lighting fixtures are powered by a driver, ballast, or transformer that controls the power (e.g., current or voltage) provided to the lamp. As with many electrical devices, drivers, ballasts, and transformers can malfunction over time or due to internal defects. Drivers, ballasts and transformers may also fail if incompatible lamps or dimmers are connected or after a surge. Non-operational drivers, ballasts, or transformers cause lamp inactivity and customer annoyance. In many lighting fixtures, the driver, ballast or transformer is located remotely from the lamp to reduce heat build-up. This means that it is often difficult for an electrician to replace the driver, ballast or transformer when the only access point is through the opening of the light fixture in the ceiling. In some cases, a large portion of the ceiling or wall must be removed to enable an electrician to access the driver, ballast or transformer or to replace the entire lighting fixture. Cutting the ceiling or wall increases the cost of the project because the customer must close the opening and repaint.

In another example, customers are increasingly conducting small to medium home improvement projects. These items may include changes in lighting, such as adding or replacing dimmers and replacing incandescent bulbs or compact fluorescent lamps with LED lamps. To save costs, the homeowner and/or electrician attempts to reuse the installed electrical box and replace only the light elements/components and the driver, ballast or transformer. However, as mentioned above, drivers are often difficult to access, thus making lighting replacement more difficult. This may result in some customers completely abandoning the lighting replacement project due to additional cost and labor

Disclosure of Invention

The present disclosure provides a new and novel recessed lighting fixture that is relatively easy to access a driver, ballast or transformer. An example recessed lighting fixture includes a fixture housing configured to receive a driver assembly housing and a lamp assembly housing. Each housing may comprise a sheet metal box having one open side. The driver assembly housing is configured to contain at least one of a driver, a ballast, and a transformer. The lamp assembly housing is configured to contain a lamp socket and/or an illumination source, such as an LED lamp, a halogen lamp, an incandescent bulb, or a compact fluorescent lamp. The open sides of the light fixture housing, the driver assembly housing, and the driver assembly housing are configured to face in the same direction. After installation in a ceiling, each open side is configured to face an interior side of the ceiling, with the light fixture housing positioned to face the opening in the ceiling to mount a light fixture or lighting source.

The lamp assembly housing is movably connected to the driver assembly housing, thereby enabling the lamp assembly housing to move or slide vertically relative to the driver assembly housing (and lamp assembly). This vertical movement allows the light fixture housing to be pulled downward through the opening in the ceiling. The ability to move downward enables an electrician to more easily access the light fixtures and associated wiring for repair and/or replacement.

The lamp assembly housing and the driver assembly housing are also configured to move horizontally together within the light fixture assembly. This enables the drive assembly housing to slide over the opening in the ceiling for easy repair 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 example embodiment, a recessed lighting fixture includes a fixture housing including a first box having an open side and a plurality of closed sides. The luminaire housing comprises a first rod connected to the inner surface of one of the closed sides and a second rod connected to the inner surface of one of the closed sides. The example recessed lighting fixture apparatus also includes a driver assembly housing including a second box having an open side and a plurality of closed sides. The driver assembly housing is positioned within the light fixture housing such that the open side of the driver assembly housing faces the open side of the light fixture housing. The driver assembly housing includes: a first slot positioned along one of the closure sides and adapted to receive a first rod to enable the driver assembly housing to slide horizontally within the light fixture housing, and a connector on a second one of the closure sides different from the one having the first slot. The example recessed lighting fixture also includes a lamp assembly housing including a third box having an open side and a plurality of closed sides. The lamp assembly housing is positioned within the light fixture housing such that the open side of the lamp assembly housing faces the open side of the light fixture housing. The lamp assembly housing includes: a second slot having an L-shape or J-shape positioned along one of the closed sides. The second slot is adapted to receive a second rod to enable the lamp assembly housing to slide horizontally or vertically within the light fixture housing. The lamp assembly housing further includes a third slot on a second one of the closed sides different from the one having the second slot, the third slot adapted to receive a connector of the driver assembly housing to slidably connect the driver assembly housing to the lamp assembly housing such that the lamp assembly housing can slide vertically relative to the driver assembly housing.

In another example embodiment, a recessed lighting fixture includes a drivecage having an open side and a plurality of closed sides. The drivecage includes a connector on one of the closed sides and a window on the one of the closed sides. The recessed lighting fixture also includes a light box having an open side and a plurality of closed sides, the light box being positioned adjacent to the driver box such that the open side of the driver box and the open side of the light box face in the same direction. The light cartridge includes a first slot on one of the closed sides adapted to receive a connector of the driver cartridge to slidably connect the driver cartridge with the light cartridge such that the light cartridge can slide vertically relative to the driver cartridge. The light cartridge further includes a second slot on the one of the closed sides and parallel to the first slot, the second slot adapted to align with the window to enable passage of the electrical cord from the light cartridge to the driver cartridge.

Other features and advantages of the disclosed systems, methods, and apparatus are described in, and will be apparent from, the following detailed description and the accompanying drawings.

Detailed Description

The present invention relates generally to recessed lighting fixtures and, more particularly, to a recessed lighting fixture with independent adjustment between a lamp assembly housing and a driver assembly housing. Example recessed lighting fixtures disclosed herein include a fixture housing, which is also referred to herein as a fixture box. The light housing is configured to be positioned above the ceiling between the support beams. In other embodiments, the light housing may be positioned behind a wall between the support posts. The light fixture housing includes a driver assembly housing, which in some cases is referred to as a driver cartridge, and a light assembly housing, which in some cases is referred to as a light cartridge. The lamp assembly housing is configured to include or be connected to a light fixture or illumination source. The driver assembly housing is configured to contain an electrical lighting driver, a ballast, and/or a transformer.

The lamp assembly housing and the driver assembly housing are configured to move horizontally within the light fixture housing. This enables the drive assembly housing, which is typically hidden from view/contact by a ceiling or wall, to be moved in front of the opening for repair or replacement. In some embodiments, the driver assembly housing and the lamp assembly housing are coupled together such that they move together in a horizontal direction relative to the fixture housing that is fixed in place. The lamp assembly housing is also configured to move vertically relative to the light fixture housing and/or the driver assembly housing. In particular, the light fixture housing may be pulled or moved downward through an opening in the ceiling (or outward through an opening in the wall) to enable relatively easy access for servicing.

While the following disclosure discusses mounting of the light fixture housing relative to the ceiling, it should be understood that the light fixture housing may be mounted behind a wall or under a floor. Generally, a light fixture housing means hidden from view while providing mechanical and electrical connections for a light fixture or other lighting source. Further, while the light fixture housing, driver assembly housing, and light assembly housing are shown as being constructed of sheet metal, it should be understood that any or all of the housings may comprise another material, such as plastic, carbon fiber composite, wood compounds, and/or combinations thereof.

Further, while the following disclosure is directed to recessed lighting fixtures, it should be understood that the fixture housing, the lamp assembly housing, and/or the driver assembly housing may be used for other types of lighting, such as track lighting, ceiling lighting, arm rest lighting, cylindrical lighting, panel lighting, or wall lighting. In these other examples, the lamp assembly housing is configured to provide electrical and/or mechanical connections for different lighting types.

Embedded lighting lamp

Fig. 1 shows an illustration of a perspective view of a recessed lighting fixture 100 including a fixture housing 102, according to an example embodiment of the present disclosure. The example luminaire housing 102 comprises a rectangular box having an open side and five closed sides. The open side is configured to face an interior surface of a ceiling and/or wall. Thus, the view of the recessed lighting fixture 100 in fig. 1 is an inverted view when the fixture housing 102 is mounted on top of a ceiling. The width of the light housing 102 is between 4 inches and 18 inches, preferably between 8 inches and 12 inches. Additionally, the length of the light housing 102 is between 6 inches and 44 inches, preferably between 24 inches and 30 inches. Further, the depth of the light housing 102 is between 3 inches and 8 inches, preferably between 4 inches and 6 inches.

The example light fixture housing 102 includes

posts

104a, 104b, 106a, and 106b on opposite facing closed sides. Rods 104 and 106 are configured to face inward within fixture housing 102. In some embodiments, rods 104 and 106 may be connected to light housing 102 by screws or rivets. In other examples, rods 104 and 106 are welded or chemically connected to light fixture housing 102. The example rods 104 and 106 are configured to have a circular or oval profile. In other examples, the rod may have a rectangular profile. Further, in some embodiments, the rods 104 and 106 may be coated and/or impregnated with an anti-friction material or chemical, such as oil.

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

The recessed lighting fixture 100 of fig. 1 also includes a driver assembly housing 110 and a lamp assembly housing 120. Each of the

housings

110 and 120 is configured to fit within the luminaire housing 102 such that the open sides of the

housings

110 and 120 face and/or align with the open sides of the luminaire housing 102. The width of the driver assembly housing 110 is between 4 inches and 18 inches, preferably between 8 inches and 12 inches. Additionally, the length of the driver assembly housing 110 is between 2 inches and 12 inches, preferably between 6 and 10 inches. The width of the lamp assembly housing 120 is between 4 inches and 18 inches, preferably between 8 inches and 12 inches. Additionally, the lamp assembly housing 110 is between 2 inches and 24 inches long, preferably between 6 inches and 12 inches long. Further, the depth of the

housings

110 and 120 is between 3 inches and 8 inches, preferably between 4 inches and 6 inches.

As discussed further in conjunction with fig. 1-9,

housings

110 and 120 are configured to move along horizontal axis 103a relative to fixed light fixture housing 102. Additionally, the lamp assembly housing 120 is configured to move along the vertical axis 103b relative to the

housings

102 and 110. It should be understood that references herein to horizontal and vertical orientation/movement are referenced to the light housing 102 and are not related to the mounting/assembly of the housing 102.

As shown in fig. 1, the width of driver assembly housing 110 and light assembly housing 120 is slightly less (e.g., 1/8 or 1/16 inches) than the width of light fixture housing 102 to enable

housings

110 and 120 to fit within housing 102 with sufficient space to be slidable along horizontal axis 103 a. Additionally, it should be appreciated that the driver assembly housing 110 and the lamp assembly housing 120 are shorter in length than the light fixture housing 102 to enable the

housings

110 and 120 to slide within the housing 102. Preferably, as discussed further in conjunction with fig. 7-9, the

housings

110 and 120 are sized relative to the housing 102 to provide sufficient space for the drive assembly housing 110 to move along the horizontal axis 103a to align with an opening made in the ceiling for the light assembly housing 120. Further, the depth of

housings

110 and 120 is equal to or slightly less (e.g., 1/2 to 1/16 inches) than the depth of light fixture housing 102.

As shown in fig. 1, driver assembly housing 110 includes

slots

112a and 112 b.

Example slots

112a and 112b are windows or sheet metal cuts extending along opposite facing closed sides of driver assembly housing 110.

Slots

112a and 112b are centrally located along the respective closed sides and extend along approximately 75% of the length of the closed sides of driver assembly housing 110. In other examples,

slots

112a and 112b may have a smaller length depending on the length of driver assembly housing 110 and light fixture housing 102 and/or the amount of space for horizontal movement. The

slots

112a and 112b are configured to enable the

respective rods

104a and 104b to pass therethrough. Where only one rod 104a is provided, the driver assembly housing 110 includes only the slot 112 a.

Slots

112a and 112b, in combination with

respective posts

104a and 104b, enable driver assembly housing 110 to slide horizontally within light fixture housing 102 while being movably secured to light fixture housing 102. For example, the combination of

slots

112a and 112b and

rods

104a and 104b prevent driver assembly housing 110 from falling vertically off of light fixture housing 102 when installed.

In some embodiments, the driver assembly housing 110 may include one or more connectors, shown in fig. 1 as

connectors

114a and 114 b. The

example connectors

114a and 114b are configured to mechanically couple the driver assembly housing 110 to the

respective slots

122a and 122b of the lamp assembly housing 120. The

connectors

114a and 114b may include at least one of a screw and lock nut, a screw nut, a hex nut, a flange nut, a slot top nut, or a wing nut. For example, the

connectors

114a and 114b may include screws that pass through the

respective slots

122a and 122b and nuts that close the ends of the screws, thereby securing the

housings

110 and 120 together. The

connectors

114a and 114b may be threaded into holes in the driver assembly housing 110 and/or may be connected to the driver assembly housing 110 by 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. Further, while fig. 1 shows the

connectors

114a and 114b positioned near the open side of the driver assembly housing 110 (e.g., within an inch of an edge), in other embodiments, the connectors may be located in the middle or bottom of the closed side of the driver assembly housing.

The illustrated embodiment shows that the driver assembly housing 110 can also include a grommet 116 on the same closed side as the

connectors

114a and 114 b. Grommet 116 is configured to fit within a window of driver assembly housing 110 to enable wires from lamp assembly housing 120 to pass through. The grommet 116 is aligned with a slot 124 on the assembly housing 120.

The example lamp assembly housing 120 includes

slots

122a and 122b for connecting to the

connectors

114a and 114b, and a slot 124 for contacting and/or aligning with the grommet 116. The

example slots

122a and 122b are configured to enable the

connectors

114a and 114b, respectively, to pass therethrough. In some cases, the

connectors

114a and 114b may contact the outer and inner portions of the closed sides of the housing 120 adjacent to the

slots

122a and 122b to reduce the free movement of the

connectors

114a and 114b within the

slots

122a and 122 b. This enables, for example, the lamp assembly housing 120 to remain in place along the vertical axis 103b until moved by an electrician. In some cases, the

connectors

114a and 114b may be manually tightened by an electrician to prevent the lamp assembly housing from moving vertically relative to the driver assembly housing. For example, the

connectors

114a and 114b may include wing nuts that are secured to the closed side of the lamp assembly housing 120 adjacent the respective slots 122.

Additionally or alternatively, grommet 116 may be configured to reduce free vertical movement between

shells

110 and 120. For example, grommet 116 may comprise a rubber or plastic material that contacts the inner edge of slot 124. The contact between grommet 116 and the edge of slot 124 creates a frictional force that prevents lamp assembly housing 120 from freely moving along vertical axis 103 b. An electrician may overcome the friction by manually moving the 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 grommet 116 and the edge of slot 124 is minimal, enabling 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 103 b. This alignment of slots 122 and 124 results in: while the driver assembly housing 110 remains stationary, the lamp assembly housing 120 is able to move or slide along the vertical axis 103 b. The length of the slots 122 and 124 defines how much the lamp assembly housing 120 can move along the vertical axis 103b, with less movement corresponding to shorter slots 122 and 124. As described above, the lamp assembly housing 120 is movable on the vertical axis 103b to enable an electrician to contact the lighting components within the housing 120 and/or to install a light fixture, a lighting source, and/or a recessed lamp assembly 150. After pulling the housing 120 down, the electrician can also more easily guide the wires from the lamp assembly housing 120 through the slot 124 and grommet 116 to the driver assembly housing. The fixed position of grommet 116 ensures that the wires do not move vertically at the boundary between

shells

110 and 120 and prevents the wires from being worn or cut by slot 124.

The example lamp assembly housing 120 of fig. 1 also includes L-shaped or J-shaped

slots

126a and 126 b.

Slots

126a and 126b are configured to receive

rods

106a and 106b, respectively. Each

slot

126a and 126b has a horizontal portion aligned with the horizontal axis 103 a. The horizontal portions of

slots

126a and 126b enable lamp assembly housing 120 to move or slide horizontally within fixture housing 102.

Slots

126a and 126b also include vertical portions that are aligned with vertical axis 103 b. The vertical portions of the

slots

126a and 126b enable the lamp assembly housing 120 to move or slide vertically relative to the driver assembly housing 110.

The horizontal portions of the

slots

126a and 126b have substantially the same length as the

slots

112a and 112 b. The

slots

112 and 126 have the same length so that the

housings

110 and 120 can have the same horizontal range of motion, which is important when the

housings

110 and 120 are connected together. In addition, the length of the vertical portions of the

slots

126a and 126b is substantially the same as the length of the

slots

122a, 122b, and 124. The

slots

122, 124, and 126 are of equal length such that the lamp assembly housing 120 can slide or move vertically relative to both the driver assembly housing 110 and the light fixture housing 102.

It should be appreciated that the location of the vertical portion of the L-shaped or J-shaped slot 126 is positioned on the respective closed side of the light fixture housing 120 relative to the desired opening in the ceiling or wall. In other words, a ceiling opening is created and/or the recessed light fixture 100 is positioned in alignment with the light fixture housing 120 such that the post 106 is located within (or proximate to) a vertical portion of the slot 126. This enables the light fixture housing 120 to be pulled down through an opening in the ceiling, as discussed further in connection with fig. 7-9. Otherwise, when the housing 120 is slid such that the rods 106 are positioned within the vertical portion of the corresponding slots 126, the closure of the ceiling will block the light assembly housing 120 from moving downward. Thus, the example L-shaped or J-shaped slot 126 enables the lamp assembly housing 120 to move along the horizontal axis 103a when the rod 106 is located within the horizontal portion of the slot 126, and enables the lamp assembly housing 120 to move along the vertical axis 103b when the rod 106 is located within the vertical portion of the slot 126. This configuration of the rod 106 and slot 126 prevents the light fixture housing 120 from falling or moving downward when not positioned over an opening in a ceiling, and also prevents the light fixture housing 120 from moving horizontally when the housing 120 is pulled downward.

The example light assembly housing 120 is configured to mechanically and/or electrically connect to a light fixture or recessed light assembly 150. The embedded light assembly 150 shown in fig. 1 includes a heat sink 152, a light emitting element 154, a light cup 156, and a trim piece 158. It should be understood that the design and appearance of the trim piece 158, the lamp cup 156, the light emitting element 154, and the heat sink 152 are to illustrate the light fixture for use in the recessed lighting fixture 100. In other embodiments, the shapes and/or designs of the heat sink 152, the light emitting element 154, the lamp cup 156, and the trim piece may be different. For example, the cup 156 and trim 158 may be replaced with a pendant and stem for a ceiling-based lighting fixture.

The heat sink 152 is configured to absorb and disperse heat generated from the light emitting elements 154. The heat sink 152 may include connectors for electrical and/or mechanical connection with the lamp assembly housing 120. The light elements 154 may include any type of lamp or illumination source, including, for example, LED lamps, halogen lamps, incandescent bulbs, or compact fluorescent lamps. The example lamp cup 156 includes a plastic and/or metal reflector and/or deflector. The light cup 156 may be configured to absorb light, reflect light, and/or reflect different colors of light depending on the desired lighting effect. In some cases, the lamp cup may include a pattern or stripe to modulate light reflection/absorption. The example trim piece 158 is configured to provide a decorative covering for an opening in a ceiling or wall. The garnish 158 is configured to be placed flush with the outside of the ceiling, for example.

The example recessed lighting fixture 100 of FIG. 1 also includes mounting

posts

160a and 160b, the mounting

posts

160a and 160b configured to be connected to ceiling beams or wall studs. Mounting

posts

160a and 160b are attached to the outer surface of the opposite facing closed side of the light fixture housing 102. Although fig. 1 shows mounting posts 160 positioned along the width of housing 102, in other examples, they may be positioned along the length of housing 102.

The example mounting posts 160 may be telescoping to enable their length to be adjusted. This telescoping feature enables the mounting bar 160 to be positioned to fit between adjacent ceiling beams or wall studs. The mounting bar 160 includes a bracket 162 at each end, the bracket 162 being configured to contact a ceiling beam or wall stud. The brackets 162 are connected at right angles so that the surfaces of the brackets contact the sides of the beam or column. Brackets 162 may include tabs with holes or windows that guide the nails into the ceiling beam or wall stud.

Fig. 2 illustrates a side view of the recessed lighting fixture 100 of fig. 1, according to an example embodiment of the present disclosure. In this illustration, the near-closed sides of the

housings

102, 110, and 120 (from the perspective of the viewer) are made transparent. As shown in fig. 2,

housings

110 and 120 have been slid all the way to the right (from the perspective of the viewer) so that rod 104 is at the end of slot 112 and rod 106 (not shown) is within the vertical portion of slot 126. This positioning of the

housings

110 and 120 enables the light fixture housing 120 to be moved upward (with reference to the viewer, but downward in the ceiling in actual use) along the vertical axis 103 b.

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 lamp assembly housing 120 includes a lamp socket 202 configured to connect to or otherwise receive or accept a connector 204 of the recessed lamp assembly 150. In some examples, the

connectors

204a and 204b may provide power and ground connections, respectively, to corresponding terminals within the lamp socket 202. Additionally or alternatively, the

connectors

204a and 204b are configured to mechanically engage corresponding connectors within the lamp socket 202. Where only a mechanical connection is made, wires are routed from the embedded light assembly 150 to the light socket 202 and through the grommet 116 to the driver 206. Otherwise, if the

connectors

204a and 204b provide electrical connection to the lamp socket 202, the wires may be routed from the lamp socket 202 through the grommet 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 embedded light assembly 150 to the light assembly housing 120.

The example driver 206 is configured to adjust or control power to the lighting elements 154. Driver 206 may include any electric driver, ballast, and/or transformer. In some examples, the driver 206 may match the AC power source to a specified DC voltage and/or regulate the voltage according to a pulse width modulation ("PWM") signal received from a dimmer switch. Additionally or alternatively, the driver 206 may send control power to the lighting elements 154 via PWM signals. The driver 206 receives power and ground from circuitry in the building (structure) that may be routed through a window 208 of the driver assembly housing 110.

As shown in fig. 2, the driver 206 is mechanically connected to a closed side (opposite the open side) of the driver assembly housing 110. The driver 206 is electrically connected (directly or indirectly) to the lighting element 154 via at least a power line and a ground line. The wires are routed through grommets 116 of the driver assembly housing 110. Grommet 116 is shown passing through a window of driver assembly housing 110 and slot 124 of light assembly housing 120. The positioning of grommet 116 prevents the wires from contacting the edges of the sheet metal of

housings

110 and 120, particularly when lamp assembly housing 120 is slid vertically relative to driver assembly housing 110. Grommet 116 thus prevents the wires from wearing or being cut from the sharp sheet metal edges of slots 124 of housing 120 and the windows of housing 110. Additionally, the ability to pull the lamp assembly housing 120 from the light fixture housing 102 makes it easier for an electrician to access to route wires from the housing 120 to the driver assembly housing 110 through the grommet 116.

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

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

Fig. 4 shows an illustration of a cross-sectional perspective view of the recessed lighting fixture 100 of fig. 3, according to an example embodiment of the present disclosure. Additionally, fig. 5 illustrates a cross-sectional side view of the recessed lighting fixture 100 of fig. 3, according to an example embodiment of the present disclosure. The cross-sections of fig. 4 and 5 are taken at the midpoint of the width of the

shells

102, 110 and 120, effectively cutting them in half.

Fig. 4 and 5 illustrate the connection between the lamp socket 202 and the

connectors

204a and 204b of the recessed light assembly 150. Specifically, the

example connectors

204a and 204b are configured to fit into corresponding openings or terminals of the lamp socket 202. The connection is made in the vicinity of the heat sink 152. Fig. 4 and 5 also illustrate the lip of the trim piece 158 configured to contact the exterior surface of a ceiling or wall. In addition to the back side of the light assembly housing 120, heat sink 152, connector 204, and light cup 156, the trim piece 158 also covers an opening in the ceiling or wall.

Fig. 6 illustrates a side view of the recessed lighting fixture 100 of fig. 5, where the closed side of the fixture housing 102 is shown as opaque, according to an example embodiment of the present disclosure. In this illustrative embodiment,

rods

104b and 106b are shown as including screws disposed through holes in light fixture housing 102. In particular, screws are placed through holes in the luminaire housing 102 and are attached to the

rods

104b and 106 b. In some embodiments, the screws may be integral with the

rods

104b and 106b to form a single structure. Alternatively, the screws may be replaced by rivets.

In this example, the lamp assembly housing 120 is raised vertically (or lowered depending on installation and perception) from the light fixture housing 102. Thus, the rod 106b is shown in the vertical portion of the L-shaped or J-shaped slot 126 b. As discussed above, the lamp assembly housing 120 may move vertically based on the rod 126b sliding within the vertical portion of the slot 126 b. As rod 106b slides along the horizontal portion of slot 126b, lamp assembly housing 120 (in combination with actuator assembly housing 110 when connected) moves along horizontal axis 103 a. To achieve horizontal movement, lamp assembly housing 120 must be fully retracted within fixture housing 102 to enable sliding of post 106b within the horizontal portion of slot 126 b.

Embedded lighting fixture use embodiments

Fig. 7 to 9 show illustrations of the

housings

110 and 120 within the recessed lighting fixture 100 of fig. 1 to 6 being moved for servicing, according to an example embodiment of the present disclosure. In these figures, the fixture housing 102 is shown with transparent closed sides to illustrate the position of the rods 104 and 106 within the

respective slots

112 and 126. In addition, fig. 7 to 9 illustrate the position of the recessed lighting fixture 100 relative to the ceiling 702, which is also shown as transparent. Thus, the views of fig. 7 through 9 are reversed compared to the perspective view of the recessed lighting fixture 100 when actually installed.

In the illustrated example of this embodiment, the ceiling 702 includes an opening 704 that is substantially slightly larger than the open side of the light fixture housing 120. In fig. 7, the

housings

110 and 120 are shown slid to the left (from the perspective of the view) so that at least a portion of the driver assembly housing 110 can face the opening 704. In some cases, the

housings

110 and 120 can be slid as far to the left as possible to align the entire open side of the driver assembly housing 110 with the opening 704. This allows, for example, an electrician to easily service and/or replace the driver 206 through the opening 704. The electrician can also route wires from the driver 206 through the grommet 116 to the lamp assembly housing 120 with relative ease.

In the position shown in fig. 7, the rod 104 is positioned within the middle section of the slot 112 or toward the right section of the slot 112, respectively. Additionally, the rod 106 is positioned within a middle section of the horizontal portion of the slot 126 or toward a right section of the horizontal portion of the slot 126, respectively. The position of the rod 106 within the horizontal portion of the slot 126 prevents the light assembly housing from being pulled (or otherwise moved) downward, which could potentially damage the ceiling.

Fig. 7 also shows an example where the rod 106 includes a wing nut that may be used to lock or prevent movement of the lamp assembly housing 120. For example, the electrician may loosen the wing nuts of the rod 106 to slide the

housings

110 and 120 horizontally or to slide the housing 120 vertically. The electrician may then tighten the wing nuts when the

housings

110 and 120 are in the desired position to prevent further movement of the

housings

110 and 120 during and/or after the maintenance is complete. For example, an electrician may tighten a wing nut when the rod 106 is at the midpoint within the vertical portion of the slot 126 to set the desired vertical position of the light assembly housing.

Transitioning from fig. 7 to fig. 8, the wing nuts are loosened from the rod 106, which enables the

shells

110 and 120 to slide horizontally. Specifically,

housings

110 and 120 are moved to the right along horizontal axis 103a within fixture housing 102. This sliding causes the driver assembly housing 110 to be covered by the ceiling 702b when aligning the light assembly housing 120 with the opening 704. Once the lamp assembly housing 120 is aligned with the opening 704, the electrician may pull or move the housing 120 downward (shown as moving upward in fig. 9) to enable relatively easy installation of the recessed lamp assembly 150. This alignment with the opening 704 is facilitated in part by the bar 106 contacting the intersection of the horizontal and vertical portions of the slot 126. At this point, the rod 106 may slide vertically through the slot 126.

Fig. 9 shows the lamp assembly housing 120 sliding along the vertical axis 103b through the opening 704 while the driver assembly housing 110 and the light fixture housing 102 remain stationary. The rod 106 is shown sliding within a vertical portion of the slot 126 (via sliding of the slot 126 relative to the rod 106). The electrician can tighten the wing nuts to lock the vertical position of the lamp assembly housing 120. In addition, 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 lamp assembly housing 120, the slots 122 slide along the connectors 114 so that the bottom ends of the slots 122 are respectively close to the connectors 114. Additionally, the bottom end of slot 124 is proximate grommet 116. Slots 122 and 124, connector 114, and grommet 116 enable lamp assembly housing 120 to move vertically relative to driver assembly housing 110 through opening 704. After repair or installation is complete, the electrician slides the light assembly housing 120 back into the light fixture housing 102 so that the trim is flush with the ceiling 702.

Alternative embodiments

As discussed throughout, rods 104 and 106 are physically connected to light housing 102 and

slots

112, 122 and 126 are included within

housings

110 and 120, respectively. In other embodiments, the stem 104 may be connected to the driver assembly housing 110 and the stem 106 may be connected to the lamp assembly housing 120. Additionally,

slots

112 and 126 may be located within fixture housing 102 to receive respective rods 104 and 106. The length and shape of the slots may be similar to the

slots

112 and 126 shown in fig. 1 through 9. This configuration will still enable

housings

110 and 120 to move horizontally within light fixture housing 102, whether or not inverted between rods 104 and 106 and between

slots

112 and 126.

Additionally or alternatively, the connector 114, grommet 116 and slots 122 and 124 may be reversed. Specifically, connector 114 and grommet 116 may be included within lamp assembly housing 120, while slots 122 and 124 are included within driver assembly housing 110. This configuration will still allow the lamp assembly housing 120 to move vertically relative to the driver assembly housing 110, whether or not inverted 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 driver assembly housing 110 may not include the connector 114, while the lamp assembly housing 120 may not include the slot 122. However, driver assembly housing 110 may include grommet 116 and light assembly housing 120 may include slot 124 to enable wiring between

housings

110 and 120. This configuration will enable the

housings

110 and 120 to slide horizontally independently.

In yet another embodiment, the light fixture housing 102 may be omitted. In this embodiment, the light fixture housing 102 may be replaced by two parallel rails positioned adjacent to the

slots

112 and 126 on the opposite facing closed sides of the

housings

110 and 120. Each track may include rods 104 and 106 that receive rods 104 and 106, respectively. The track may be similar to mounting posts 160 and include brackets for attachment to a ceiling beam or wall stud. In this embodiment, the mounting bar 160 may be omitted. As an alternative to this embodiment, the tracks may include

slots

112 and 126, while the

housings

110 and 120 include rods 104 and 106, respectively. In either case, the

housings

110 and 120 can slide horizontally relative to the rails. In addition, the housing 120 may slide vertically relative to the rail.

Fig. 10 and 11 show diagrams of perspective views of a recessed lighting fixture 100 having a fixture housing 1002 that includes a lamp assembly housing 1004 and a driver assembly housing 1006, according to another example embodiment of the present disclosure. In the embodiment illustrated in fig. 10, the driver assembly housing 1006 is blocked from view by the cover 1007. The example cover 1007 can be integral with the light fixture housing 1002 or can be connected to the light fixture housing 1002. In some examples, as shown in fig. 11, the lid 1007 may be omitted.

The example driver assembly housing 1006 shown in fig. 11 has a smaller width compared to the driver assembly housing 110 of fig. 1. The smaller width of the driver assembly housing 1006 limits the placement of the driver 206, for example, to ensure that the driver 206 is accessible when the driver assembly housing 1006 is slid into an opening in a ceiling. It should be appreciated that the width of the driver assembly housing 1006 is approximately equal to or slightly less than the width of the light housing 1002 at the segment 1008. This ensures that when the light assembly housing 1004 is slid into the segment 1008, the driver assembly housing 1006 aligns with the opening in the ceiling and/or moves beyond the cover 1007 of the light fixture housing 1002.

The embodiment illustrated in fig. 11 includes a rail 1010 configured to enable the driver assembly housing 1006 to slide relative to the light fixture housing 1002. Instead of slots 112 described in conjunction with fig. 1, rails 1010 are integral with light housing 1002 or otherwise connected to light housing 1002. The driver assembly housing 1006 includes a track 1012 configured to connect to the track 1010 of the light fixture housing 1002. The rails 1012 slide between the rails 1010, thereby enabling the driver assembly housing 1006 to move or slide relative to the light fixture housing 1002. In other examples, similar to the rod 104 of fig. 1, the driver assembly housing 1006 may include a rod that connects or contacts the track 1010. The light assembly housing 1004 may also be movably connected to the light fixture housing 1002 using rails similar to those used for the driver assembly housing 1006.

The example light fixture housing 1002 of fig. 10 and 11 includes supports 1020 and 1022 for mounting the wand 160. The

supports

1022a and 1022b are configured to connect the respective mounting

posts

160a and 160b to the light fixture housing 1002 at opposite ends. In addition, supports 1020a and 1020b are configured to connect respective mounting

posts

160a and 160b to light fixture housing 1002 at opposite sides. The presence of

supports

1020a and 1020b at opposite sides of light fixture housing 1002 provides installation flexibility based on the layout of the beams or supports in the building. For example, an electrician may change the pole 160 from support 1022 to support 1020 to better position or secure the light fixture housing 1002 in the ceiling based on the position and spacing of the cross beam. The telescoping configuration of the mounting posts 160 enables them to be used in either of the supports 1020 and 1022, regardless of differences in the length of the ends and sides of the light housing 1002.

It should be understood that the mounting bar 160 of fig. 10 and 11 may be attached to a bracket 1024 that provides a mechanical connection to a support or beam using nails or other fasteners. In some cases, the bracket 1024 may be replaced with the bracket 162 of fig. 1. Additionally or alternatively, the

brackets

1024 and 162 may be interchangeable. In fig. 10 and 11, the bracket 1024 is shown to include a lip 1026, the lip 1026 configured to catch or otherwise contact an edge of the support or beam. The lip 1026 may help to conform the bracket 1024 to a support or beam. Additionally, the alignment of the lip 1026 with the bottom of the support or beam helps ensure that the light housing 1002 is mounted at the proper height relative to the ceiling. Mounting the fixture housing 1002 too high into the ceiling may prevent the recessed light fixture from being properly mounted.

Fig. 12 shows an illustration of the recessed lighting fixture 100 of fig. 10 and 11 with the recessed light assembly 1200 removed from the light assembly housing 1004, according to an example embodiment of the present disclosure. The recessed light assembly 1200 may be removed to enable access for servicing, for example, the driver 206 of fig. 10 and 11. After removal, the lamp assembly housing 1004 and the driver assembly housing 1006 are slid to the left (from the perspective of the viewer), thereby aligning the driver assembly housing 1006 with the opening 1202. The driver assembly housing 1006 may then be slid or pulled out of the light housing 1002 through the opening 1202 to enable repair and/or replacement of the driver 206.

Fig. 13 shows an illustration of a perspective view of the embedded light component 1200 of fig. 12, according to an example embodiment of the present disclosure. The embedded light assembly 1200 is similar to the embedded light assembly 150 of fig. 1 and 2 and is configured to be electrically and mechanically connected to a light socket within the light assembly housing 1004.

In the example of fig. 13, the embedded light assembly 1200 includes a trim piece 1302 configured to cover an opening in a ceiling. The assembly 1200 also includes a lamp cup 1304 configured to direct, reflect, and/or refract light in a pre-specified manner. The support ring 1306 is connected to the base of the light cup 1304 and is configured to engage or otherwise connect to the trim piece 1302.

The example recessed light assembly 1200 also includes a heat sink 1308 configured to dissipate heat from a bulb or other lighting element. The wires may be routed through holes in the heat sink to provide electrical connections with wires or terminals in a lamp socket in the lamp assembly housing 1004. The wing connector 1310 is connected to the side of the heat sink 1308 to mechanically connect the recessed lamp assembly 1200 to the lamp socket within the lamp assembly housing 1004. While two wing connectors 1310 are shown, it should be understood that additional or fewer connectors may be used. The wing connector 1310 is configured to mechanically engage a corresponding mating structure within a lamp socket. In some embodiments, the wing connector 1310 may be press-fit connected to a lamp socket. In other examples, the wing connector 1310 may lock into a lamp socket. In still other examples, the wing connector 1310 may be mechanically connected to the lamp socket via screws or other fasteners.

Conclusion

It should be understood that various changes and modifications to the example embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
