Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to luminaire systems, and more particularly to recessed luminaires. BACKGROUND

[0002] Recessed lighting often uses various luminaire designs to provide additional lighting in a room, such as providing general lighting, wall washing lighting, accent lighting, etc. However, recessed luminaire fixtures often encounter obstacles within a ceiling that hinder the fixture from desired rotation and / or aiming at various desired angles, such as being able to rotate in a full circle or 360 degrees within a ceiling opening. For example, a ceiling joist or other obstacle can block rotation of a structure used to mount and hold a luminaire fixture within a recessed ceiling opening.

[0003] Accordingly, a solution that enables rotation and / or aiming of a recessed luminaire fixture even when a luminaire holding structure is blocked is desirable. SUMMARY

[0004] The present disclosure relates generally to luminaire systems, and more particularly to recessed luminaires. In an example embodiment, a rotation plate is provided for holding a recessed luminaire in a ceiling opening. The rotation plate includes: a mouse trap bracket configured to hold the rotation plate within the ceiling opening; and a plurality of grooves defined in the plate. The plurality of grooves are configured to allow the recessed luminaire to rotate relative to the ceiling opening while the rotation plate remains stationary relative to the ceiling opening.

[0005] The rotation plate can have various embodiments. For example, the rotation plate can further include a plurality of screws configured to engage the recessed luminaire through the plurality of grooves. In another example, a spring can engage each mouse trap bracket to a corresponding bracket opening on the rotation plate. In yet another example, the rotation plate can include a center engagement point configured to allow at least one screw to engage the recessed luminaire through the center engagement point. In another example, the rotation plate can include a plurality of support structures located on the rotation plate, and the plurality of support structures can be configured to provide structural support to the rotation plate.

[0006] In another aspect, a luminaire system is provided that is configured to be installed in a ceiling. The luminaire system includes at least a luminaire and a rotation plate configured to engage the luminaire. The rotation plate is configured to allow the luminaire to move from a first position in the ceiling to a second position in the ceiling while the rotation plate remains stationary relative to the ceiling.

[0007] The luminaire system can have many variations. For example, the luminaire system can include a mounting bracket. The mounting bracket can be configured to directly engage the luminaire, and the rotating plate can be configured to directly engage the mounting bracket. In another example, the rotating plate can have a plurality of mousetrap brackets configured to move from a compressed position to an expanded position, and the plurality of mousetrap brackets can be configured to support the recessed luminaire system in the ceiling in the expanded position. In yet another example, the rotating plate can have a plurality of grooves, and the grooves can be configured to allow the luminaire to move from a first position to a second position while the rotating plate remains stationary.

[0008] In yet another aspect, a recessed luminaire system is provided that is configured to be installed in a ceiling opening. The recessed luminaire system includes a recessed luminaire, a mounting bracket configured to engage the recessed luminaire, and a rotating plate configured to engage the mounting bracket. The rotating plate has one or more mousetrap brackets and one or more rotating grooves. The one or more mousetrap brackets are configured to secure the luminaire system in the ceiling opening, and the rotating grooves are configured to allow the recessed luminaire to rotate in the ceiling opening independently of rotation of the rotating plate.

[0009] The recessed luminaire system can have various different embodiments. For example, the recessed luminaire system can further include a plurality of screws configured to engage the rotating plate to the mounting bracket through the one or more rotating grooves. In another example, the recessed luminaire system can include a plurality of screws configured to engage the mounting bracket to the recessed luminaire through a plurality of openings defined in the mounting bracket. In yet another example, one or more springs can couple the one or more mousetrap brackets to the rotating plate, and the one or more mousetrap brackets can be configured to move from a first compressed position to a second relaxed position.

[0010] These and other aspects, objects, features, and embodiments will become apparent from the following description and the accompanying claims. BRIEF DESCRIPTION OF DRAWINGS

[0012] The accompanying drawings illustrate exemplary embodiments only and are therefore not intended to limit the scope. Elements and features shown in the drawings are not necessarily drawn to scale, but rather the emphasis is on clearly illustrating the principles of the exemplary embodiments. Additionally, certain dimensions or arrangements may be enlarged to aid in visually conveying such principles. In the drawings, the same reference numerals used in different figures may denote the same or corresponding, but not necessarily, elements. Detailed Implementation

[0013] In the following paragraphs, exemplary embodiments will be described in more detail with reference to the accompanying drawings. In the description, well-known components, methods, and / or processing techniques are omitted or briefly described. Furthermore, references to different features of the embodiments do not imply that all embodiments must include the referenced features.

[0014] In some exemplary embodiments, the rotating plate is configured to allow the recessed luminaire to rotate in a circular manner when the luminaire is installed in an opening in the ceiling (including when the rotating plate itself cannot rotate relative to the ceiling). For example, the rotating plate may be configured to engage a mounting bracket, which in turn engages the recessed luminaire. After the luminaire is installed in the opening in the ceiling, the rotating plate serves to support and hold the luminaire in the ceiling. Once installed, the orientation of the luminaire can be changed based on the desired lighting requirements of the environment by rotating the luminaire, the mounting bracket, and the rotating plate to alter the light produced by the device. However, in some cases, the rotating plate may encounter obstacles that impede further rotation of the rotating plate, such as ceiling beams. Therefore, the disclosed embodiments of the rotating plate are configured to allow further rotation of the luminaire even when the rotating plate can no longer rotate, for example, allowing the luminaire to rotate in a full circle (or 360 degrees) even when the rotating plate can no longer rotate.

[0015] For example, Figures 1-5An embodiment of a rotating plate 100 is shown, configured to engage with a mounting bracket 200 and a recessed luminaire 300, and the rotating plate 100 is configured to allow the luminaire 300 to rotate in a circular motion when mounted in a recessed opening in a ceiling 500. For example, rotation of the luminaire 300 can occur even when the rotating plate 100 contacts an obstruction in the ceiling 500 that prevents the rotating plate 100 from continuing to rotate; such obstruction is, for example, a ceiling support beam 550, which will be discussed further below. The illustrated rotating plate 100 is attached to the mounting bracket 200 via screws 400, and the mounting bracket 200 is similarly attached to the luminaire 300 via screws 410, as will be discussed further below.

[0016] The rotating plate 100 shown includes at least a groove 120 defined in the plate 100, a plurality of mousetrap supports 110, a central engagement point 130, and a support structure 140. The plate 100 is formed in a generally circular shape and can be formed of a variety of materials, such as metal plates, plastics, alloys, etc.

[0017] The recess 120 is configured to allow a screw 400, which engages with the luminaire 300, to slide along the recess 120, thereby allowing rotation of the luminaire 300 when the device 300 is installed in an embedded opening in the ceiling 500. The recess 120 allows the shaft of the screw 400 to pass through it, while engaging and supporting the head of the screw 400. The shaft of the screw 400 can then be screwed into an opening on a mounting bracket 200, which is then fastened to the recessed luminaire 300 by screws 410. Once the screw 400 is fastened to pass through the plate 100 and into the mounting bracket 200 and the device 300, the recess 120 is configured to guide the screw 400 in a circular rotational manner about the central axis A1 of the rotating plate 100, while the relative position of the rotating plate 100 is maintained, which in turn allows the luminaire 300 to be guided in a similar circular rotational manner. The recess 120 extends about the rotating plate 100 in a generally semi-circular manner, and in the illustrated embodiment, two recesses 120 are arranged opposite each other. However, in other embodiments, one or more grooves may be defined in the plate, and the grooves may be positioned at various different points around the rotating plate according to the desired engagement points on various lighting fixtures.

[0018] The rotating plate 100 also has a central engagement point 130, which receives the shaft of the screw 400 through which it passes and supports the head of the screw 400 (similar to the groove 120). The central engagement point 130 is located at the center of the rotating plate 100 along the central axis A1, and is configured to facilitate supporting and securing the rotating plate 100 to the mounting bracket 200, while allowing the mounting bracket 200 (and consequently the luminaire 300) to rotate relative to the rotating plate 100 about the central axis A1.

[0019] Furthermore, the illustrated mousetrap bracket 110 engages with a bracket opening 112 on the rotating plate 100 via a spring portion 114 and is configured to support the rotating plate 100 and the lighting fixture 300 in the ceiling 500 after installation. The bracket 110 is configured to flatten along the body of the recessed lighting fixture 300 during installation and return to its previous open state once installed in the ceiling 500, engaging with the ceiling 500 and holding the lighting fixture 300 in the recessed opening of the ceiling 500. In the illustrated embodiment, two mousetrap brackets 110 are present, arranged transversely across the rotating plate 100. However, in other embodiments, one or more mousetrap brackets may be provided, and they may be arranged at different points around the rotating plate.

[0020] Support structures 140 are disposed on the rotating plate 100 to provide additional strength and structural integrity to portions of the plate 100. Three of the illustrated support structures 140, which are ridge-shaped and made of a different material, are present around the area where the mousetrap bracket 110 of the plate 100 engages with the bracket opening 112. In other embodiments, one or more support structures may have different shapes and be arranged in different locations, depending on the desired location of the additional support. Furthermore, the rotating plate 100 has an opening 150 for reducing the overall weight of the rotating plate 100 and the materials used. Although the illustrated rotating plate has two openings 150, which are semi-circular in shape between the central engagement point 130 and the groove 120, any number of openings of various shapes may exist in the plate depending on the desired weight and structural integrity.

[0021] The illustrated luminaire 300 is a wall washer module configured to be installed in an embedded opening in the ceiling 500. As described above, the luminaire 300 is configured to indirectly engage with the rotating plate 100 via a mounting bracket 200, and is configured to provide illumination to the room. Once installed in the ceiling 500, the luminaire 300 rotates circularly about a central axis A1. The illustrated luminaire 300 is a Halo ML flexible series wall washer design. However, several different embedded luminaires may be used in various embodiments. Furthermore, the mounting bracket 200 is configured to engage the rotating plate 100 to the luminaire 300 and facilitates rotation of the device 300 via the plate 100. The illustrated mounting bracket 200 has an approximately U-shaped shape with three openings 210 configured to receive screws 400 from the rotating plate 100 and two openings 220 configured to receive screws 410 screwed into the openings 310 on the luminaire 300. However, the mounting bracket can have various shapes and a variety of numbers and positions of openings, depending on the type of luminaire used in each embodiment and how the rotating plate is configured to engage with the specific luminaire via the mounting bracket. Furthermore, in some embodiments, the mounting bracket can be completely excluded, in which case the rotating plate can be configured to engage directly with the luminaire. Therefore, in some embodiments, the mounting bracket can directly engage the rotating plate and / or the luminaire, and in some embodiments, the rotating plate can engage the luminaire directly or indirectly. The mounting bracket 200 can be made of various materials, such as metal, plastic, alloy, etc.

[0022] In use, the rotating plate 100 is attached to the mounting bracket 200 by a screw 400, which passes through the groove 120 of the rotating plate 100 and is screwed into the opening 210 of the mounting bracket 200. The mounting bracket 200 is attached to the lighting device 300 by a screw 410, which passes through the opening 210 of the mounting bracket 200 and is screwed into the opening 310 of the lighting device 300.

[0023] The user installs the lighting fixture 300 into the recessed opening 510 defined in the ceiling 500. During the insertion of the lighting fixture 300 into the opening 510, as the user pushes the lighting fixture 300 into the ceiling 500, the mousetrap bracket 110 flattens along the body of the recessed lighting fixture 300 by bending at the spring portion 114. When the user fully inserts the lighting fixture 300 into the opening 510 in the ceiling 500, the mousetrap bracket 110 springs back to its previous open state and engages the ceiling 500 to hold the lighting fixture 300 in the recessed opening 510, as... Figure 4 As shown in the image.

[0024] Once the lighting fixture 300 is installed, it can be rotated about the central axis A1 to a desired orientation based on the room's lighting needs. During rotation, the mousetrap bracket 110 may encounter obstacles in the ceiling 500, such as ceiling beams 550. Figure 5 An exemplary scenario is shown, where arrows indicate exemplary directions of rotation, and dashed circles highlight exemplary points of contact between one of the mousetrap brackets 110 and one of the ceiling joists 550 shown. In the illustrated example, once the mousetrap bracket 110 encounters the ceiling joist 550, the rotating plate 100 may cease to rotate due to obstruction. The lighting fixture 300 may still require further rotation based on desired lighting in the room. Therefore, the groove 120 on the rotating plate 100 allows the lighting fixture 300 to continue rotating because the screws 400 connecting the rotating plate 100 to the mounting bracket 200 (which in turn connects to the lighting fixture 300) can continue to travel along the groove 120 (even when the body of the rotating plate 100 remains fixed in place). Although Figure 4 and 5 The diagram shows a ceiling support beam, but any number of different obstructions in the ceiling can prevent the rotation of the rotating plate 100, and thus the rotation of the lighting fixture becomes necessary due to the recess.

[0025] Therefore, the rotating plate is configured to allow the lighting fixture 300 to continue rotating about the central axis A1 relative to the ceiling 500 even when the rotating plate 100 itself is blocked (and therefore cannot move relative to the ceiling 500).

[0026] The above provides only one embodiment of the rotating plate, and the rotating plate can have various different embodiments. For example, Figure 6 Another embodiment of a rotating plate 600, similar to the rotating plate 100 discussed above, is shown. For example, the rotating plate 600 has a recess 620 similar to the recess 120 described above, which receives a screw passing through it and allows rotation of the lighting fixture, and the plate 600 has a plurality of bracket openings 612 similar to the bracket opening 112 described above, which can receive one or more mousetrap brackets therein. The rotating plate 600 is configured to allow the user to make various choices regarding where to attach one or more mousetrap brackets based on the specific arrangement of the ceiling and possible ceiling obstructions. One or more elements and / or descriptions provided above for rotating plates 100, 600 may be combined with another rotating plate 100, 600.

[0027] also, Figure 7The illustration shows another embodiment of a rotating plate 700, similar to the rotating plates 100 and 600 discussed above. For example, the rotating plate 700 has a plurality of openings 712 defined therein, similar to the bracket openings 112 discussed above, configured to receive one or more mousetrap brackets therein. The rotating plate 700 is configured to allow a user to make various choices regarding where to attach one or more mousetrap brackets based on the specific arrangement of the ceiling and possible ceiling obstructions. The rotating plate 700 further has one or more mounting brackets 715 extending therefrom, configured to engage directly with a lighting fixture via screws extending through an opening 717, which can be screwed directly into a corresponding opening on the lighting fixture, thus eliminating the need for separate and distinct mounting brackets to allow the rotating plate 700 to engage with the lighting fixture. The specific number and arrangement of the openings and / or mounting brackets may vary based on the respective lighting fixture. In addition, as discussed above, one or more elements and / or descriptions provided above for rotating plates 100, 600, and 700 may be combined with any of the other rotating plates 100, 600, and 700.

[0028] While specific embodiments have been described in detail herein, the description is by way of example. The features of the exemplary embodiments described herein are representative, and in alternative embodiments, certain features, elements, and / or steps may be added or omitted. Furthermore, modifications to aspects of the exemplary embodiments described herein can be made by those skilled in the art without departing from the scope of the appended claims, the scope of which is to be interpreted in the broadest possible sense to include modifications and equivalent structures.
