Description

Embedded lighting device with independent adjustment function between lighting component and driving component

This application claims the benefits of US Design Patent Application No. 29 / 591,403 filed on January 19, 2017, the entire contents of which are incorporated herein by reference.

The invention discloses an embedded light fixture, in particular an embedded light fixture having an independent adjustment function between a lighting component and a driving component.

When you walk into any room or shop, 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 displayed. However, this can change quickly (worse) if there are unusable lighting fixtures, flashing lighting, high-pitched lighting and / or lighting that looks too bright or too dark in the environment. Essentially, most lighting is a low-key decorative component that performs its function as expected without attracting (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 compliant with architectural / electrical specifications. To satisfy different customer preferences and decoration styles, manufacturers invest most of their efforts to create different lighting designs and features. This includes providing different shapes and colors of lighting fixtures and / or shades, different types of lighting (eg, track lighting, recessed lighting, pendant lighting, etc.), and different types of Light source (eg, incandescent, compact fluorescent, light emitting diode ("LED"), etc.).

Spend very little effort designing lighting fixtures for repair or replacement. From the customer's point of view, these features will not be seen after installation and therefore will not be understood. In addition, because lighting fixtures are installed before the gypsum board (or plaster) is suspended, the installation of lighting fixtures in a new building (or gut-rehab construction) is usually not a problem. This enables electrician technicians to easily attach lighting fixtures to wall studs or ceiling studs and connect / route electrical wires. Therefore, manufacturers provide the minimum features required to secure a lighting fixture to a wall or ceiling.

Unfortunately, this lack of attention from manufacturers often makes it difficult to repair or update lighting fixtures after initial installation. For example, many lighting fixtures are powered by a driver, ballast, or transformer that controls the power (eg, current or voltage) that provides the lighting. As with many electrical devices, drives, ballasts, and transformers may fail after prolonged use or due to internal defects. Drivers, ballasts and transformers may also malfunction if unsuitable lighting or dimmers are connected, or after a power surge. Unusable drivers, stabilizers or transformers cause unusable lighting and cause customer distress. In many lighting fixtures, a driver, ballast, or transformer system is placed away from the lamp to reduce heat build-up. This means that when the only point of access is through an opening in the ceiling of a lighting assembly, it is often difficult for an electrician technician to replace a driver, ballast, or transformer. In some cases, most of the ceiling or wall must be removed to allow an electrician to access a driver, ballast or transformer, or replace the entire lighting fixture. Because the customer must close the opening and repaint it, cutting the ceiling or wall will increase the cost of the project.

In another example, more and more customers are working on small to medium scale home improvement projects. These items can include lighting changes such as adding or replacing dimmers, and replacing incandescent bulbs or integrated fluorescent lamps with LED lights. To save costs, the homeowner and / or electrician attempt to reuse the installed electrical box and simply replace the light-emitting components / assemblies and drivers, stabilizers or transformers. However, as mentioned above, drives are often difficult to access, making replacement lighting more difficult. Due to additional costs and efforts, this may cause some customers to completely abandon lighting replacement projects.

This disclosure provides a new and innovative embedded lighting fixture that is relatively accessible to a driver, ballast, or transformer. Exemplary recessed lighting fixtures include a lighting fixture housing configured to contain a drive assembly housing and a lighting assembly housing. Each housing may include a metal plate box having one open side. The drive assembly housing is configured to contain at least one of a driver, a stabilizer, and a transformer. The lighting assembly housing is configured to contain a lighting socket and / or a lighting source, such as an LED lamp, a halogen lamp, an incandescent light bulb, or an integrated fluorescent light bulb. The open side of the lighting unit case, the driving unit case, and the driving unit case are arranged to face the same direction. After being installed in the ceiling, each open side is configured to face the inside of the ceiling, where the lighting assembly housing is placed to face the opening in the ceiling to install lighting fixtures or lighting sources.

The lighting component housing is movably connected to the driving component housing, so that the lighting component housing can move or slide vertically relative to the driving component housing (and the lighting equipment component). This vertical movement enables the lighting assembly housing to be pulled down through an opening in the ceiling. The ability to move down makes it easier for an electrician technician to access the lighting fixtures and associated electrical wires for repair and / or replacement.

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

In an exemplary embodiment, the embedded lighting fixture apparatus includes a lighting fixture housing, and the lighting fixture housing includes a first box body having an open side and a closed side. The lighting fixture housing includes a first pole connected to an inner surface of one of the closed sides, and a second pole connected to an inner surface of one of the closed sides. An exemplary embedded lighting fixture also includes a drive assembly housing including a second box having an open side and a closed side. The driving component housing is located in the lighting equipment housing, so that the open side of the driving component housing faces the open side of the lighting equipment housing. The drive assembly housing includes a first slot positioned along one of the closed sides and adapted to receive the first rod, so that the drive assembly housing can slide horizontally within the lighting fixture housing, and has a first slot. The connector on the second closed side is different from the closed side of the slot. The exemplary embedded lighting fixture apparatus further includes a lighting assembly housing including a third box body having an open side and a closed side. The lighting component housing is located in the lighting equipment housing, so that the open side of the lighting component housing faces the open side of the lighting equipment housing. The lighting assembly housing includes a second slot having an L-shape or a J-shape positioned along one of the closed sides. The second slot is adapted to receive the second pole so that the lighting assembly housing can slide horizontally or vertically within the lighting fixture housing. The lighting module housing also includes a third slot on a second closed side different from the closed side having the second slot, and the third slot is suitable for receiving a connector of the driving module housing to connect the driving module housing It is slidably connected to the lighting component housing so that the lighting component housing can slide vertically relative to the driving component housing.

In another exemplary embodiment, a recessed lighting fixture includes a drive box having an open side and a closed side. The drive box includes a connector on one of the closed sides and a window on the one of the closed sides. The embedded lighting equipment also includes a lighting box with an open side and a closed side. The lighting box is located near the driving box, so that the open side of the driving box and the open side of the lighting box face the same direction. The lighting box includes a first slot on one of the closed sides, and the slot is adapted to receive a connector of the driving box to slidably connect the driving box and the lighting box so that the lighting box can be opposite to The drive case slides vertically. The lighting box also includes a second slot located on the one closed side and parallel to the first slot. The second slot is adapted to be aligned with the window so that the electrical wires can pass from the lighting box to the driving box. .

Other features and advantages of the disclosed systems, methods, and devices will be described in the following embodiments and drawings, and will be apparent from the embodiments and drawings.

The disclosure generally relates to an embedded lighting device, and more particularly to an embedded lighting device having an independent adjustment function between a lighting component housing and a driving component housing. An exemplary embedded lighting fixture disclosed herein includes a light fixture housing, which is also referred to herein as a fixture box. A fixture housing is configured to be placed above a ceiling between support beams. In other embodiments, the fixed housing may be positioned behind a wall between the support posts. Fixed housings include driver assembling housing, which is called a driver box in some cases, and light assembly housing, which is called a lighting box in some cases (Light box). The lighting assembly housing is configured to include or be connected to a lighting fixture or lighting source. The drive assembly housing is configured to contain an electric lighting driver, a ballast, and / or a transformer.

The lighting unit case and the driving unit case are arranged to move horizontally within the lighting fixture case. This allows the drive assembly housing, which is normally obscured by ceilings or walls, to be moved to the front of the opening for repair or replacement. In some embodiments, the driving component housing and the lighting component housing are connected together so that they move together in a horizontal direction relative to the lighting fixture housing fixed in place. The lighting component housing is also configured to move vertically relative to the lighting fixture housing and / or the drive component housing. Specifically, the lighting assembly housing may be pulled down or moved through the opening in the ceiling (or moved outward through the opening in the wall) to enable relatively easy maintenance.

Built-in lighting equipment

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 with an open side and five closed sides. The open side is configured to face the interior surface of the ceiling and / or wall. Therefore, when the lighting fixture housing 102 is mounted on the top of the ceiling, the view of the embedded lighting fixture 100 of FIG. 1 is an upside-down view. The lighting fixture housing 102 has a width between 4 inches and 18 inches, preferably between 8 inches and 12 inches. In addition, the lighting fixture housing 102 has a length between 6 inches and 44 inches, preferably between 24 inches and 30 inches. In addition, the lighting fixture housing 102 has a depth 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 opposing faces facing the closed side. The poles 104 and 106 are arranged so as to face the inside of the lighting fixture housing 102. In some embodiments, the poles 104 and 106 may be connected to the lighting fixture housing 102 by screws or rivets. In other examples, the poles 104 and 106 may be welded or chemically connected to the lighting fixture housing 102. Exemplary poles 104 and 106 are configured to have a circular or oval profile. In other examples, the pole may have a rectangular outline. Further, in some embodiments, the rods 104 and 106 may be coated and / or injected with anti-friction materials or chemicals such as oil.

As shown in FIG. 1, the poles 104 and 106 are located on the closed, opposite sides of the lighting fixture housing 102. For example, the pole 104a is located opposite the pole 104b. The poles 104 and 106 are located near the open side of the lighting fixture housing 102. In some embodiments, the poles 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 in the middle of the closed side of the lighting fixture housing 102. Although FIG. 1 shows a pair of poles 104 and 106 facing each other, 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 component housing 110 and a lighting component housing 120. Each of the housings 110 and 120 is configured to fit within the lighting fixture housing 102 such that the open sides of the housings 110 and 120 and the open sides of the lighting fixture housing 102 face and / or align. The drive assembly housing 110 has a width between 4 inches and 18 inches, preferably between 8 inches and 12 inches. In addition, the drive assembly housing 110 has a length between 2 inches and 12 inches, preferably between 6 and 10 inches. The lighting assembly housing 120 has a width between 4 inches and 18 inches, preferably between 8 inches and 12 inches. In addition, the lighting assembly housing 110 has a length between 2 inches and 24 inches, preferably between 6 inches and 12 inches. In addition, the housings 110 and 120 have a depth between 3 inches and 8 inches, preferably between 4 inches and 6 inches.

As further discussed in conjunction with FIGS. 1 to 9, the housings 110 and 120 are configured to move along the horizontal axis 103 a relative to the stationary lighting fixture housing 102. The lighting unit case 120 is arranged to move along the vertical axis 103 b with respect to the cases 102 and 110. As can be understood, the reference to the horizontal and vertical directions / movements in this article refers to the housing 102 of the lighting equipment, and has nothing to do with the way the housing 102 is mounted / rack-mounted.

As illustrated in FIG. 1, the driving component housing 110 and the lighting component housing 120 have a width that is slightly smaller (for example, 1/8 or 1/16 inch) than that of the lighting equipment housing 102 so that the housings 110 and 120 can With sufficient space, it fits inside the housing 102 and can slide along the horizontal axis 103a. In addition, it should be understood that the driving component housing 110 and the lighting component housing 120 have a length smaller than that of the lighting equipment housing 102 so that the housings 110 and 120 can slide inside the housing 102. Preferably, as further discussed in conjunction with FIGS. 7 to 9, the sizes of the housings 110 and 120 are relative to the size of the housing 102 to provide sufficient movement of the drive assembly housing 110 along the horizontal axis 103 a. The space is aligned with an opening made in the ceiling for the lighting assembly housing 120. In addition, the cases 110 and 120 have a depth equal to or slightly smaller than (for example, 1/2 to 1/16 inch) the lighting fixture case 102.

As shown in FIG. 1, the drive unit housing 110 includes slots 112 a and 112 b. Exemplary slots 112a and 112b are window or sheet metal cutouts that extend along opposing faces of the closed side of the drive assembly housing 110. The slots 112a and 112b are centered along the respective sides and extend along approximately 75% of the length of the sides of the 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 size of the space for horizontal movement. The slots 112a and 112b are configured so that the corresponding poles 104a and 104b can pass through. In the case where only one pole 104a is provided, the drive assembly housing 110 includes only the slot 112a.

The combination of the slots 112 a and 112 b with the corresponding poles 104 a and 104 b enables the drive assembly housing 110 to slide horizontally within the lighting fixture housing 102 while being movably fixed to the lighting fixture housing 102. For example, the slots 112a and 112b are combined with the poles 104a and 104b to prevent the drive assembly housing 110 from falling vertically from the lighting fixture housing 102 during installation.

In some embodiments, the driving assembly housing 110 may include one or more connectors, such as the connectors 114 a and 114 b shown in FIG. 1. Exemplary connectors 114a and 114b are configured to be mechanically coupled to respective slots 122a and 122b of the drive module housing 110 to the lighting module 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). For example, the connectors 114a and 114b may include screws passing through the corresponding slots 122a and 122b and nuts closing the ends of the screws, thereby fixing the housings 110 and 120 together. The connectors 114a and 114b may be screwed into holes in the drive assembly housing 110, and / or may be connected to the drive assembly housing 110 via screws, rivets, solder, welding, and / or chemical fixings. Although FIG. 1 shows two connectors 114a and 114b, it should be understood that other embodiments may include fewer connectors or additional connectors. In addition, although FIG. 1 shows that the connectors 114a and 114b are located on the open side (eg, one inch from the edge) of the drive module housing 110, in other embodiments, the connector may be located in the middle of the side of the drive module 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. The buckle 116 is configured to fit within a window of the drive assembly housing 110 so that a wire from the lighting assembly housing 120 can pass through. The buckle 116 is aligned with the slot 124 on the lighting assembly housing 120.

The exemplary lighting assembly housing 120 includes slots 122a and 122b for connecting to the connectors 114a and 114b, and slots 124 for contacting and / or aligning with the buckle 116. Exemplary slots 122a and 122b are configured to enable connectors 114a and 114b to pass through, respectively. In some cases, the connectors 114a and 114b may contact the outer and inner portions of the 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 122b. This allows, for example, the lighting assembly housing 120 to remain in place along the vertical axis 103b until it is moved by an electrician technician. In some cases, the connectors 114a and 114b may be manually locked by an electrician technician to prevent the lighting assembly housing from moving vertically relative to the drive assembly housing. For example, the connectors 114a and 114b may include wing nuts that are locked near the sides of the lighting assembly housing 120 adjacent to the corresponding slot 122.

Additionally or alternatively, the buckle 116 may be configured to reduce free vertical movement between the housings 110 and 20. For example, the buckle 116 that contacts the inner edge of the slot 124 may include a rubber or plastic material. The contact between the buckle 116 and the edge of the slot 124 generates friction to prevent the lighting assembly housing 120 from moving freely along the vertical axis 103b. The friction force can be overcome by the electrician technician manually moving the housing 120. This configuration enables the housing 120 to be lowered or raised to a desired position suitable for maintenance and / or installation. In other examples, the contact between the buckle 116 and the edge of the slot 124 is minimal, enabling 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 when 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, and the shorter slots 122 and 124 correspond to less movement. As described above, the lighting assembly housing 120 can be moved in the vertical axis 103b, so that an electrician can access the lighting assembly in the housing 120 and / or install lighting fixtures, lighting sources and / or embedded lighting assemblies 150. After the casing 120 is pulled down, the electrician technician can further easily pass the electric wires through the slot 124 and the retaining ring 116 from the lighting component housing 120 to the driving component housing. The rest position of the buckle 116 ensures that the electric wire does not move vertically at the boundary between the cases 110 and 120 and prevents the electric wire from being worn 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. The slots 126a and 126b are configured to receive the poles 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 126 a and 126 b enable the lighting assembly housing 120 to move or slide horizontally within the lighting fixture housing 102. The slots 126a and 126b also include vertical portions aligned with the vertical axis 103b. The vertical portions of the slots 126 a and 126 b enable the lighting assembly housing 120 to move or slide vertically relative to the driving assembly housing 110.

The horizontal portions of the slots 126a and 126b have substantially the same length as the slots 112a and 112b. The slots 112 and 126 having the same length enable the housings 110 and 120 to have the same range of horizontal movement, which is important when it is assumed that the housings 110 and 120 are connected together. The lengths of the vertical portions of the slots 126a and 126b are substantially the same as the lengths of the slots 122a, 122b, and 124. The slots 122, 124, and 126 having the same length enable the lighting assembly housing 120 to slide or move vertically with respect to both the driving assembly housing 110 and the lighting fixture housing 102.

It should be understood that the location of the vertical portion of the L-shaped or J-shaped slot 126 in the ceiling or wall is positioned on the corresponding side of the lighting assembly housing 120 as intended openings. In other words, an opening in the ceiling will be created and / or the recessed light fixture 100 will be aligned with the lighting assembly housing 120 so that the pole 106 is located within the vertical portion of the slot 126 (or near the vertical portion of the slot 126) section). As discussed further in connection with FIGS. 7 to 9, this enables the lighting assembly housing 120 to be pulled down through an opening in the ceiling. Otherwise, when the housing 120 slides, the closed portion of the ceiling will prevent the lighting assembly housing 120 from moving downward, so that the pole 106 is positioned within the vertical portion of the corresponding slot 126. Thus, when the pole 106 is positioned within the horizontal portion of the slot 126, the exemplary L-shaped or J-shaped slot 126 enables the lighting assembly housing 120 to move along the horizontal axis 103a, and when the pole 106 is positioned within When in the vertical portion, an exemplary L-shaped or J-shaped slot 126 enables the lighting assembly housing 120 to move along the vertical axis 103b. When not positioned on the ceiling opening, the arrangement of the pole 106 and the slot 126 prevents the lighting assembly housing 120 from falling or moving downward, and also prevents the lighting assembly housing 120 from horizontally when the housing 120 is pulled down. mobile.

The exemplary lighting assembly housing 120 is configured to be mechanically and / or electrically connected to the 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 decorative piece 158, the lampshade 156, the light emitting element 154, and the heat sink 152 are used for the lighting fixture of the embedded lighting fixture 100. In other embodiments, the shapes and / or designs of the heat sink 152, the light-emitting element 154, the lamp cover 156, and the decoration may be different. For example, for a hanging lighting fixture, the lampshade 156 and the decorative member 158 may be replaced with a suspension and a 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 electrical and / or mechanical connection with the lighting assembly housing 120. The light emitting element 154 may include any type of lamp or illumination light source, including, for example, an LED lamp, a halogen lamp, an incandescent bulb, or an integrated fluorescent lamp. Exemplary lampshades 156 include plastic and / or metal reflectors and / or deflectors. Depending on the desired lighting effect, the lampshade 156 may be configured to absorb light, reflect light, and / or reflect different colors of light. In some cases, the lampshade may include a pattern or stripes to adjust light reflection / absorption. The exemplary trim 158 is configured to provide a decorative covering to an opening in a ceiling or wall. The decorative member 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 poles 160a and 160b configured to be connected to a ceiling beam or wall pillar. The mounting rods 160 a and 160 b are connected to the outer surfaces of the opposite sides of the closed side of the lighting fixture housing 102. Although FIG. 1 shows the mounting rods 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 so that its length can be adjusted. This telescopic feature enables the mounting pole 160 to be positioned to fit between adjacent ceiling beams or wall pillars. The mounting rod 160 includes a bracket 162 at each end that is configured to contact a ceiling beam or a wall pillar. The brackets 162 are connected at right angles so that the surface of the brackets contacts the sides of the beams or studs. The bracket 162 may include tabs including holes or windows that guide nails into ceiling beam posts or wall posts.

FIG. 2 illustrates a side view of the embedded lighting fixture 100 of FIG. 1 according to an exemplary embodiment of the present disclosure. In this figure, the near-closed sides of the housings 102, 110, and 120 (from the perspective of the observer) are made transparent. As shown in FIG. 2, the housings 110 and 120 slide all the way to the right (from an observer's perspective) so that the rod 104 is located at the end of the slot 112 and the rod 106 (not shown) is tied to the vertical of the slot 126 Within. This positioning of the housings 110 and 120 enables the lighting assembly housing 120 to move upward along the vertical axis 103b (relative to the viewer, but downwards when actually used in the ceiling).

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 the lighting assembly housing 120 including a lighting socket 202 configured to connect or otherwise receive or receive a connector 204 of the embedded lighting assembly 150. In some examples, the connectors 204a and 204b can provide power, respectively, and are grounded to corresponding terminals in the lighting socket 202. Additionally or alternatively, the connectors 204a and 204b are configured to mechanically engage respective connectors within the lighting socket 202. With only a mechanical connection, the wires run from the embedded lighting assembly 150 wires to the lighting socket 202 and pass through the retaining ring 116 to the driver 206. Otherwise, if the connectors 204a and 204b provide an electrical connection to the lighting socket 202, a wire may 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 fix the embedded lighting assembly 150 to the lighting assembly housing 120.

The exemplary driver 206 is configured to regulate or control a power source to the light emitting element 154. The 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 specific DC voltage and / or adjust the voltage based on a pulse width modulation (PWM) signal received from a dimmer switch. Additionally or alternatively, the driver 206 may transmit a control power to the light emitting element 154 through a PWM signal. The driver 206 receives power and ground from the circuit in the structure, which can be set through the window 208 of the driving component housing 110.

As shown in FIG. 2, the driver 206 is mechanically connected to the closed side (the opposite side to the open side) of the drive assembly housing 110. The driver 206 is electrically connected to the light emitting element 154 (directly or indirectly) via at least one power line and a ground line. The wires are routed through the buckle 116 of the drive assembly housing 110. The buckle 116 is shown as passing through the window of the drive assembly housing 110 and the slot 124 of the lighting assembly housing 120. Especially when the lighting assembly housing 120 slides vertically with respect to the driving assembly housing 110, the positioning of the buckle 116 prevents the electric wires from contacting the edges of the metal plates of the housings 110 and 120. Therefore, the buckle 116 prevents the electric wires from being abraded or spliced from the slot 124 of the case 120 and the sharp metal plate edge of the window of the case 110. In addition, the ability to pull out the lighting component housing 120 from the lighting equipment housing 102 provides an electrician technician with more accessible wiring to pass wires from the housing 120 to the drive component housing 110 through the buckle 116.

FIG. 3 illustrates a perspective view of the embedded lighting fixture 100 of FIGS. 1 and 2 having the embedded lighting assembly 150 connected to the lighting assembly housing 120 according to an exemplary embodiment of the present disclosure. Once installed, the lighting assembly housing 120 may slide back vertically into the lighting fixture housing 102 so that the decoration 158 contacts the outer surface of the ceiling and / or wall to cover the opening. In addition, 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 installed flush with the inside of the ceiling. Conversely, there may be a gap of several inches between the ceiling and the housing 102. In these cases, the vertical adjustment function of the lighting assembly housing 120 enables an electrician to set the required height to ensure that the decoration is flush with the ceiling. The lighting assembly housing 120 may be held vertically via a retaining ring 116 contacting the edge of the slot 124 and / or via a lock nut of the connector 122.

FIG. 4 illustrates a cross-sectional perspective view of the embedded lighting fixture 100 of FIG. 3 according to an exemplary embodiment of the present disclosure. In addition, FIG. 5 shows a cross-sectional side view of the embedded lighting fixture 100 of FIG. 3 according to an exemplary embodiment of the present disclosure. The cross sections of FIGS. 4 and 5 are obtained by effectively cutting the halves of the housings 102, 110, and 120 in half.

4 and 5 show the connection between the lighting socket 202 of the embedded lighting assembly 150 and the connectors 204a and 204b. Specifically, the exemplary connectors 204a and 204b are configured to mate with corresponding openings or terminals of the lighting socket 202. The connection occurs near the heat sink 152. 4 and 5 also show the lip of the decorative member 158 configured to contact the outer surface of the ceiling or wall. In addition to the rear side of the lighting assembly housing 120, the radiator 152, the connector 204, and the lamp cover 156, the decoration 158 covers the opening in the ceiling or wall.

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

In this example, the lighting assembly housing 120 rises vertically (or decreases according to installation and perception) from the lighting fixture housing 102. Therefore, the pole 106b is shown in a vertical portion of the L-shaped or J-shaped slot 126b. As described above, the lighting assembly housing 120 may be vertically moved according to the sliding of the rod 126b within the vertical portion of the slot 126b. As the pole 106b slides along the horizontal portion of the slot 126b, the lighting assembly housing 120 (when connected, coupled with the drive assembly housing 110) moves along the horizontal axis 103a, while the pole 106 moves along the horizontal of the slot 106 Partially sliding. To produce horizontal movement, the lighting assembly housing 120 must be fully retracted into the lighting fixture housing 102 so that the pole 106b can slide within the horizontal portion of the slot 126b.

Examples of use of embedded lighting equipment

7 to 9 are schematic diagrams of housings 110 and 120 in the embedded lighting fixture 100 of FIGS. 1 to 6 that are moved for maintenance according to an exemplary embodiment of the present disclosure. In these drawings, the lighting fixture housing 102 is shown with a transparent closed side to show the positions of the poles 104 and 106 within the corresponding slots 112 and 126. 7 to 9 show positions of the recessed lighting fixture 100 with respect to the ceiling 702 which is also shown as transparent. Therefore, the views of FIGS. 7 to 9 provide opposite views 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 approximately larger than the open side of the lighting assembly housing 120. In FIG. 7, the housings 110 and 120 are shown to slide to the left (from an observer's perspective), so that at least a portion of the drive assembly housing 110 can face the opening 704. In some cases, the housings 110 and 120 can be slid to the left as far as possible to align the entire open side of the drive assembly housing 110 with the opening 704. This allows, for example, an electrician to easily repair and / or replace the driver 206 through the opening 704. An electrician can also relatively easily route the wires from the driver 206 through the buckle 116 to the lighting assembly housing 120.

In the position shown in FIG. 7, the poles 104 are respectively located in the middle portion of the slot 112 or in the towards the right section. In addition, the poles 106 are respectively located in a middle portion or a right-facing portion of the horizontal portion of the slot 126. The location of the pole 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.

Figure 7 also shows an example where the pole 106 includes a wing nut that can be used to lock or prevent movement of the lighting assembly housing 120. For example, an electrician technician may loosen the thumb nut of the rod 106 to slide the housings 110 and 120 horizontally or slide the housing 120 vertically. Then, when the housings 110 and 120 are in a desired position, the electrician technician can lock the wing nut to prevent the housings 110 and 120 from moving further during the repair period and / or after the repair is completed. For example, when the pole 106 is located at a midpoint within the vertical portion of the slot 126, the electrician technician can lock the wing nut to set the desired vertical position of the lighting assembly housing.

Turning from FIG. 7 to FIG. 8, the wing nut is loosened from the rod 106, which enables the housings 110 and 120 to slide horizontally. Specifically, the housings 110 and 120 move to the right within the lighting fixture housing 102 along the horizontal axis 103a. When the lighting assembly housing 120 is aligned with the opening 704, this sliding causes the driving assembly housing 110 to be covered by the ceiling 702b. Once the lighting assembly housing 120 is aligned with the opening 704, an electrician technician can pull down or move the housing 120 (shown as moving up in Figure 9) to enable relatively easy installation of the embedded lighting assembly 150. The rod 106 partially helps align the opening 704 by contacting the intersection of the horizontal and vertical portions of the slot 126. At this point, the pole 106 may slide vertically through the slot 126.

FIG. 9 shows that when the driving component housing 110 and the lighting equipment housing 102 remain stationary, the lighting component housing 120 slides along the vertical axis 103 b through the opening 704. The pole 106 is shown sliding within a vertical portion of the slot 126 (via sliding relative to the slot 126 of the pole 106). An electrician may lock the wing nut to lock the vertical position of the lighting 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.

Moreover, as shown in FIG. 9, during the vertical sliding of the lighting assembly housing 120, the slot 122 slides along the connector 114 so that the bottom ends of the slot 122 approach the connector 114, respectively. In addition, the bottom end of the slot 124 is close to the retaining ring 116. The slots 122 and 124, the connector 114, and the retaining ring 116 enable 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 completed, the electrician technician slides the lighting assembly housing 120 back into the lighting fixture housing 102 so that the decoration 158 is flush with the ceiling 702.

Alternative embodiment

As discussed throughout, the poles 104 and 106 are physically connected to the lighting fixture housing 102, and the slots 112, 122, and 126 are included in the housings 110 and 120, respectively. In other embodiments, the pole 104 may be connected to the driving component housing 110 and the pole 106 may be connected to the lighting component housing 120. In addition, the slots 112 and 126 may be located in the lighting fixture housing 102 to receive the corresponding poles 104 and 106. The length and shape of the slot may be similar to the slots 112 and 126 shown in FIGS. 1 to 9. Although the poles 104 and 106 and the slots 112 and 126 are reversed, this configuration still enables the housings 110 and 120 to move horizontally within the lighting equipment housing 102.

Additionally or alternatively, the connector 114, the retaining ring 116, and the slots 122 and 124 may be reversed. Specifically, the connector 114 and the buckle 116 may be included in the lighting component housing 120, while the slots 122 and 124 are included in the driving component housing 110. Although the connector 114 and the slot 122 are reversed, this configuration can still make the lighting assembly housing 120 move vertically relative to the driving assembly housing 110.

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 buckle 116 and the lighting assembly housing 120 may include a slot 124 so that electrical wires can be arranged between the housings 110 and 120. This configuration enables the housings 110 and 120 to slide horizontally independently.

In yet another embodiment, the lighting fixture housing 102 may be omitted. In this embodiment, the lighting fixture housing 102 may be replaced by two parallel rails near the slots 112 and 126 on opposite sides of the closed side of the housings 110 and 120. Each of the tracks receiving the poles 104 and 106, respectively, may include poles 104 and 106. The track may be similar to a mounting pole 160 and include a bracket for attaching to a ceiling beam or wall pillar. In this embodiment, the mounting lever 160 may be omitted. As an alternative in this embodiment, the track may include slots 112 and 126, and the housings 110 and 120 include poles 104 and 106, respectively. In either case, the housings 110 and 120 can slide horizontally relative to the track. In addition, the housing 120 may slide vertically with respect to the rail.

10 and 11 illustrate perspective views of a recessed lighting fixture 100 having a lighting fixture housing 1002 including a lighting component housing 1004 and a drive component housing 1006 according to another exemplary embodiment of the present disclosure. In the embodiment shown in FIG. 10, the drive assembly housing 1006 is blocked from view by the cover 1007. The exemplary cover 1007 may be integrated with the lighting fixture housing 1002 or may be connected to the lighting fixture housing 1002. In some examples, as shown in FIG. 11, the cover 1007 may be omitted.

Compared to the drive module housing 110 shown in FIG. 1, the exemplary drive module housing 1006 shown in FIG. 11 has a smaller width. The small width of the drive assembly housing 1006 limits the placement of the drive 206 to ensure, for example, that the drive 206 is accessible when the drive assembly housing 1006 slides into an opening in the ceiling. It should be understood that the width of the driving assembly housing 1006 is substantially equal to or slightly smaller than the width of the lighting fixture housing 1002 located at the portion 1008. This ensures that when the lighting assembly housing 1004 slides into the portion 1008, the drive assembly housing 1006 aligns and / or moves beyond the cover 1007 of the lighting fixture housing 1002 with the opening in the ceiling.

The embodiment shown in FIG. 11 includes a track 1010 configured to enable the drive assembly housing 1006 to slide relative to the lighting fixture housing 1002. The track 1010 is integrated with or otherwise connected to the lighting fixture housing 1002 instead of the slot 112 described with reference to FIG. 1. The drive assembly housing 1006 includes a track 1012 configured to be connected to a track 1010 of the lighting fixture housing 1002. The track 1012 slides between the tracks 1010, so that the driving component housing 1006 can move or slide relative to the lighting equipment housing 1002. In other examples, the drive assembly housing 1006 may include a rod similar to the rod 104 of FIG. 1, which connects or contacts the rail 1010. The lighting component housing 1004 may also be movably connected to a lighting fixture housing 1002 using a track similar to that used to drive the component housing 1006.

The exemplary lighting fixture housing 1002 of FIGS. 10 and 11 includes supports 1020 and 1022 for mounting a rod 160. At the opposite ends, the supports 1022a and 1022b are configured to connect the respective mounting rods 160a and 160b to the lighting fixture housing 1002. In addition, on the opposite side, the supports 1020a and 1020b are configured to connect the corresponding mounting rods 160a and 160b to the lighting fixture housing 1002. The presence of the supports 1020a and 1020b on opposite sides of the lighting fixture housing 1002 provides installation flexibility according to the layout of cross-beams or supports in the structure. For example, an electrician technician can change the pole 160 from the support 1022 to the support 1020 to better position or fix the lighting fixture housing 1002 in the ceiling according to the position and interval of the beam. Although the lengths of the ends and sides of the lighting equipment housing 1002 are different, the telescopic structure of the mounting rod 160 allows them to be used for the support 1020 or 1022.

It should be understood that the mounting rods 160 of FIGS. 10 and 11 may be connected to the bracket 1024, which uses nails or other fixings to provide a mechanical connection with the support or the beam. 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 Figures 10 and 11, the bracket 1024 is shown as including an end edge 1026 configured to grasp or otherwise contact an edge of a support or beam. The end edge 1026 may help align the bracket 1024 with a support or beam. In addition, the alignment of the end edge 1026 with the bottom of the support or beam helps to ensure that the lighting fixture housing 1002 is mounted at an appropriate height relative to the ceiling. Installing the lighting fixture housing 1002 too high into the ceiling may prevent the recessed lighting fixture from being installed properly.

FIG. 12 is a diagram illustrating the embedded lighting fixture 100 of FIG. 10 and FIG. 11 with the embedded lighting assembly 1200 removed from the lighting assembly housing 1004 according to an exemplary embodiment of the present disclosure. The recessed lighting assembly 1200 can be removed to enable access, for example, to the driver 206 of FIGS. 10 and 11 for repair. After removal, the lighting assembly housing 1004 and the driving assembly housing 1006 slide to the left (from an observer's perspective), so that the driving assembly housing 1006 is aligned with the opening 1202. Then, the driving component housing 1006 can be slid or pulled out from the lighting equipment housing 1002 through the opening 1202 to enable the driver 206 to be repaired and / or replaced.

FIG. 13 shows a perspective view of the embedded lighting assembly 1200 of FIG. 12 according to an exemplary embodiment of the present disclosure. The embedded lighting assembly 1200 is similar to the embedded lighting assembly 150 of FIGS. 1 and 2 and is configured to be electrically and mechanically connected to the lighting socket in the lighting assembly housing 1004.

In the example of FIG. 13, the recessed lighting assembly 1200 includes a decoration 1302 configured to cover an opening in a ceiling. The assembly 1200 also includes a lampshade 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 lampshade 1304 and is configured to engage or otherwise connect to the decoration 1302.

The example recessed lighting assembly 1200 also includes a heat sink 1308 configured to dissipate heat from a lighting bulb or other light emitting element. The wires can be arranged through holes in the heat sink to provide electrical connection to the wires or terminals in the lighting socket in the lighting assembly housing 1004. A wing connector 1310 is connected to the side of the heat sink 1308 to mechanically connect the embedded lighting assembly 1200 to a lighting socket in the lighting assembly housing 1004. Although 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 lighting socket. In some embodiments, the wing connector 1310 may be press-fittingly connected to a lighting socket. In other examples, the wing connector 1310 may be locked into a lighting socket. In other examples, the wing connector 1310 may be mechanically connected to the lighting socket via screws or other fixtures.
