## Title
Twist and lock mounting bracket

## Abstract

A twist-and-lock mounting bracket may secure a lighting fixture to a mounting surface. The twist-and-lock mounting bracket may define an aperture having features corresponding to the shape of a twist-and-lock element disposed on a housing of a lighting fixture. Accordingly, the twist-and-lock element may be configured to extend through the aperture while the corresponding features of the twist-and-lock element and the aperture are aligned. The housing may then be rotated such that the tabs do not align with the corresponding features of the aperture, and the twist-and-lock element is thereby prevented from sliding through the aperture. The mounting bracket may be secured to a junction box positioned within a mounting surface, or it may be secured to a biasing bracket having one or more second resilient members configured to engage the interior of a recessed can light, such that the lighting fixture may be secured to the recessed can light.

Also, various embodiments of the lighting fixture 100 may comprise lighting elements that emit different levels of illumination at different color temperatures. The number of lighting elements used may also be utilized to determine the level of illumination emitted by the lighting fixture 100.
One or more circuit elements are disposed within the lighting fixture 100. In various embodiments, the circuit elements may be configured to provide an electrical current to the at least one lighting element. For example, in the case of the at least one lighting element being an LED or COB LED, the at least one circuit element may be driver circuitry. In such embodiments, the driver circuitry may comprise a circuit portion configured to convert an input alternating current (AC) line voltage to a direct current (DC) voltage. In various embodiments, the driver circuitry may comprise a circuit portion configured to control the current being applied to the one or more LEDs. The driver circuitry, in various embodiments, may further comprise a circuit portion configured to allow a user to adjust the brightness of the light emitted from the lighting fixture 100 through the use of a dimmer switch. These circuitry portions are commonly known and understood in the art, and thus will not be described in detail herein. In various embodiments, the driver circuitry may include other circuitry portions and/or the circuitry portions described herein may not be distinct circuitry portions. For example, in some embodiments, the circuitry portion that converts an AC line voltage to a DC voltage may also control the current being applied to the one or more LEDs.
In various embodiments, the one or more circuit elements may be disposed within a chamber accessible via the circuit access door 155. In other embodiments, the one or more circuit elements are sealed within the lighting fixture 100 such that a user cannot easily and/or inadvertently come into contact with the one or more circuit elements, in accordance with relevant safety guidelines (e.g., UL certification, etc.).
D. Back Cover 150
As shown in FIG. 3, the lighting fixture 100 may comprise a back cover 150. The back cover 150 may be configured to seal the interior of the lighting fixture 100 from dust, dirt, moisture and/or the like; enclose the electrical components (e.g., the at least one lighting element and/or the one or more circuit elements) of the lighting fixture 100; provide structural support for the lighting fixture 100; prevent a user from coming into contact with the electrical components of the lighting fixture 100; and/or the like. In some embodiments, one or more connecting wires 140 in electrical communication with the at least one lighting element and/or the circuit components may be configured to provide electrical communication between the at least one lighting element and/or the circuit components and an input (e.g., line voltage). In various embodiments, a first end of the one or more connecting wires 140 may be secured to the electrical components of the lighting fixture (e.g., the at least one lighting element and/or the circuit components), and a second end of the connecting wires 140 may be secured in a halo, WAGO, quick connect, or other connector. In various embodiments, the second end of the connecting wires may be configured to be secured to an input (e.g., a line voltage wire) via a wire nut and/or the like.
In various embodiments, the lighting fixture 100 may be configured to be detachably secured to a mounting bracket 200. Accordingly, the back cover 150 may comprise a twist and lock element 130. As described herein, the twist and lock element 130 may be configured to detachably couple the lighting fixture 100 to a mounting bracket 200 having a twist and lock receiver 230. For example, the twist and lock element 130 may have one or more tabs 135 configured to engage a twist and lock tab receiver 235. As will be described in greater detail herein, the mounting bracket 200 may comprise a thin, rigid plate defining an aperture sized such that at least a portion of the twist and lock element 130 may extend through the aperture, and the entirety of the tabs 135 may pass through the aperture, such that the twist and lock element 130 and the tabs 135 may rotate without colliding with the rigid plate. In various embodiments, the aperture has a shape corresponding to the shape of the twist and lock element 130 and the one or more tabs 135, such that the twist and lock element 130 may extend through the aperture only when the tabs 135 are aligned with aperture features corresponding to the tabs 135. As a non-limiting example, the twist and lock element 130 may have a substantially round, tube shape central body element extending away from the lighting fixture 100. The twist and lock element 130 may have one or more tabs 135 extending laterally away from the curved sides of the central body element. The twist and lock receiver may thus have a substantially round shape (e.g., circular) having a diameter larger than the central body element, with one or more tab receivers 235, having a shape corresponding to the one or more tabs 135. Accordingly, the profile of the twist and lock receiver 230 corresponds to the shape of the twist and lock element 130. With at least a portion of the twist and lock element 130 extending through the aperture such that the tabs may rotate without colliding with the rigid plate, the lighting fixture 100 may be rotated with respect to the mounting bracket 200 until the tabs 135 are not aligned with the corresponding aperture features, and the rigid plate of the mounting bracket 200 prevents the twist and lock element 130 and tabs 135 from disengaging the mounting bracket 200. In various embodiments, the tabs 135 and twist and lock element 130 may be configured to frictionally engage the mounting bracket 200 such that the frictional force between the tabs 135 and the mounting bracket 200 impedes rotation of the lighting fixture 100 relative to the mounting bracket.
II. Mounting Bracket 200
FIGS. 4A-9 illustrate various embodiments of mounting brackets. Specifically, FIGS. 4A-4B illustrate a mounting bracket 200a according to one embodiment. In the illustrated embodiment of FIG. 4A, the mounting bracket 200a is configured to secure the lighting fixture 100 to a junction box 300. For example, the illustrated mounting bracket 200a comprises a twist and lock receiver 230a having twist and lock tab receivers 235a associated therewith for receiving tabs 135. In various embodiments, the twist and lock receiver 230a may comprise a twist and lock tab receiver 235a for each tab 135. The twist and lock tab receiver 235a may be configured such that each twist and lock tab receiver 235a may receive a tab 135; the mounting bracket 200a and the lighting fixture 100 may then be rotated with respect to each other such that each tab 135 is secured to the mounting bracket 200a via the twist and lock receiver 230a. In various embodiments, the twist and lock element 130 and twist and lock receiver 230a may be configured to secure the mounting bracket relative to the lighting fixture 100.
The mounting bracket 200a may also include attachment elements 210a, 215a. The attachment elements 210a, 215a may be configured to secure the mounting bracket 200a to a junction box 300 (as shown in FIG. 4B) and/or biasing bracket 240. For example, screws may be used to secure the mounting bracket 200a to a junction box 300 (e.g., via attachment elements 215a, 310) or screws may be used to secure the mounting bracket 200 to a biasing bracket 240. In various embodiments, the attachment elements 210a, 215a may be configured to secure the mounting bracket 200a to a variety of sized and/or shaped junction boxes (e.g., 3 inch diameter junction boxes, 4 inch diameter junction boxes, round junction boxes, square junction boxes, octagonal junction boxes, and/or the like). As a non-limiting example, attachment elements 210a may be configured to secure the mounting bracket 200a to a first size junction box 300 (e.g., a 3 inch diameter junction box) via a fastener (e.g., a screw) and attachment elements 215a may be configured to secure the mounting bracket 200a to a second size junction box 300 (e.g., a 4 inch diameter junction box) via a fastener. In other embodiments, a variety of methods may be used to secure a mounting bracket 200a to a biasing bracket 240 and/or a junction box 300.
Moreover, in the illustrated embodiment of FIG. 4A, the mounting bracket 200a additionally comprises one or more standoffs 205 configured to maintain a minimum distance between a mounting surface (e.g., a ceiling) and the mounting bracket 200a. As shown in FIG. 4B, the one or more standoffs 205 may be configured to engage the mounting surface outside of the diameter of the junction box 300. Moreover, the one or more standoffs 205 may accommodate a junction box 300 protruding from the mounting surface, as shown in FIG. 4B. The one or more standoffs 205 may engage the mounting surface to thereby impede the mounting bracket 200a from being secured to the junction box 300 such that a bottom surface of the mounting bracket 200a is in contact with a top surface of the junction box 300 when the junction box 300 protrudes from the mounting surface by a distance less than the length of the one or more standoffs 205. As a non-limiting example, the lighting fixture 100 may be configured such that the outer edge of the frame 110 may engage the mounting surface when the lighting fixture 100 is engaged with a mounting bracket 200a positioned at the minimum distance away from the mounting surface. Thus, the one or more standoffs 205 may be configured to position the mounting bracket 200a relative to the mounting surface such that the outer edge of the frame 110 of the lighting fixture 100 engages the mounting surface when secured to the mounting bracket 200a. 
FIGS. 5A-5B illustrates a mounting bracket 200a secured to a biasing bracket 240a according to one embodiment. As shown in FIG. 5A, the mounting bracket 200a may be secured to the biasing bracket 240a utilizing one or more fasteners (e.g., screws) extending through one or more of the attachment elements 210a, 215a and one or more corresponding attachment elements of the biasing bracket 240a. In such a configuration, the mounting bracket 200a and biasing bracket 240a may be collectively configured to secure the lighting fixture 100 to a recessed can lighting fixture.
FIG. 6 illustrates a mounting bracket 200 in accordance with another embodiment. The mounting bracket 200 may be configured to be secured to the lighting fixture 100. For example, the illustrated mounting bracket 200 comprises a twist and lock receiver 230 having twist and lock tab receivers 235 associated therewith for receiving tabs 135. In various embodiments, the twist and lock receiver 230 may comprise a twist and lock tab receiver 235 for each tab 135. The twist and lock tab receiver 235 may be configured such that each twist and lock tab receiver 235 may receive a tab 135; the mounting bracket 200 and the lighting fixture 100 may then be rotated with respect to each other such that each tab 135 is secured to the mounting bracket 200 via the twist and lock receiver 230. In various embodiments, the twist and lock element 130 and twist and lock receiver 230 may be configured to secure the mounting bracket relative to the lighting fixture 100. As shown in FIG. 6, the mounting bracket 200 may be approximately half an annulus, and/or the like.
As shown in FIG. 6, the mounting bracket 200 may also include attachment elements 210, 215. The attachment elements 210, 215 may be configured to secure the mounting bracket 200 to a junction box 300 and/or biasing bracket 240 (as shown in FIG. 6). For example, screws may be used to secure the mounting bracket 200 to a junction box 300 (e.g., via attachment elements 215, 310) or screws may be used to secure the mounting bracket 200 to a biasing bracket 240. In other embodiments, a variety of methods may be used to secure a mounting bracket 200 to a biasing bracket 240 and/or a junction box 300.
In various embodiments, the mounting bracket may be made of aluminum, plastic, and/or other appropriate material.
III. Biasing Bracket 240

In various embodiments, the biasing bracket 240a may comprise one or more first resilient members 245a as shown in FIG. 5A secured to corresponding width adjusting members 241a, one or more second resilient members 246a, and a wire conduit 250a. The wire conduit 250a may comprise an aperture, slot, and/or the like defined and extending through the biasing bracket 240a. The wire conduit 250a may be configured to receive the connecting wires 140 of the lighting fixture 100, such that the lighting fixture 100 may be secured in electrical connection with an input (e.g., line voltage).
In various embodiments, the one or more first resilient members 245a and one or more second resilient members 246a may be configured to frictionally engage the interior of a recessed can light and thereby frictionally secure the biasing bracket 240a, the mounting bracket 200, and the lighting fixture 100 to the can light. In various embodiments, the first resilient members 245a may comprise a resilient material (e.g., metal rods) biased to an extended position as shown in FIG. 5A. Accordingly, when placed within the interior of a can light, the first resilient members 245a bias against the interior surface of the can light and thereby frictionally engage the interior surface of the can light. In various embodiments, the first resilient members 245a may engage one or more receiving features of the can light (e.g., apertures, clips, and/or the like) configured to engage the first resilient features 245a to further impede the lighting fixture 100 from disengaging the can light. Similarly, the second resilient members 246a may comprise a resilient material (e.g., metal) biased to an extended position, such that when placed within the interior of a can light, the second resilient members 246a bias against the interior surface of the can light and thereby frictionally engage the interior surface of the can light.
As illustrated in FIG. 5A, the biasing bracket 240a may comprise one or more width adjustment members 241a. The width adjustment members 241a may be slidably coupled to the biasing bracket 240a, and configured such that the first resilient members 245a may be moved between two or more positions, such as a narrow position at which the first resilient members are near a center portion of the lighting fixture 100, and a wide position at which the first resilient members are positioned some distance away from the center portion of the lighting fixture. Moreover, as illustrated in FIG. 5A, the width adjustment features 241a may be locked into a particular position using a fastener 242a (e.g., a bolt). As a non-limiting example, after the width adjustment features 241a are positioned in a desired position, the fastener 242a may be tightened to secure the width adjustment features into position.
As a non-limiting example, the width adjusting members 241a may be configurable between the narrow position configured to engage a first diameter can light and the wide position configured to engage a second diameter can light. Moreover, in various embodiments, the width adjusting members 241a and corresponding first resilient members 245a may be removable as shown in FIG. 5B, such that the one or more second resilient members 246a may engage a third diameter can light that is smaller than the first and second diameter can lights. As a non-limiting example, the lighting fixture 100 may be secured to a 4-inch diameter can light utilizing the one or more second resilient members 246a when the width adjusting members 241a are removed, the lighting fixture 100 may be secured to a 5-inch diameter can light utilizing the one or more first resilient members 245a when the width adjusting members 241a are in the narrow configuration, and the lighting fixture 100 may be secured to a 6-inch diameter can light utilizing the one or more first resilient members 245a when the width adjusting members 241a are in the wide configuration.
As shown in FIG. 7, when the biasing bracket 240a and the mounting bracket 200a are secured to the lighting fixture 100, the components of each of the biasing bracket 240a and mounting bracket 200a may be entirely within the perimeter of the lighting fixture frame 120, such that, when installed against a mounting surface, the biasing bracket 240a and the mounting bracket 200a are not visible.
FIG. 8 illustrates a rear view of a biasing bracket 240a and mounting bracket 200a secured to a lighting fixture 100.

Moreover, as shown in FIG. 8, the biasing bracket 240a may be secured to mounting bracket 200a. In such configurations, the mounting bracket 200a may be configured to mount within a can light such that an edge of the mounting bracket 200a is flush with an edge of the can light.
FIG. 9 illustrates a biasing bracket 240 secured to a mounting bracket 200 according to another embodiment. As illustrated in FIG. 9, the biasing bracket 240 may comprise one or more first resilient members 245 and a wire conduit 250. The wire conduit 250 may be configured to receive the connecting wires 140 or the like there-through, such that the lighting fixture 100 may be secured in electrical connection with an input (e.g., a line voltage). The one or more first resilient members 245 may be configured such that the one or more first resilient members 245, biasing bracket 240, and/or mounting bracket 200 may be placed within a recessed can light. The first resilient members 245 may bias against the interior walls of the recessed can light, thereby frictionally securing the lighting fixture 100 into the recessed can light. In various embodiments, the biasing bracket 240 may be made of plastic, aluminum, or other appropriate material. In some embodiments the first resilient members 245 may be made of the same or different material as the biasing bracket 240. In other embodiments, the first resilient members 245 may be otherwise biased, as may be desirable so as to secure the same relative to a recessed can light or other fixture receptacle.
As shown at least in FIG. 9, in embodiments wherein the lighting fixture 100 is to be installed into a recessed can light, an Edison connector 190 may be secured to the connecting wires 140 (e.g., via the Edison connector wires 192 and halo/WAGO/quick connect connector 195 and/or wire nuts). The Edison connector may be screwed or otherwise secured into the existing can light bulb receptacle, such that the lighting fixture 100 may be secured into electric communication with the input (e.g., line voltage).
It should be understood that some embodiments may not include a biasing bracket 240. For example, as shown in FIG. 1, the lighting fixture 100 may be installed using a mounting bracket 200 without a biasing bracket 240. In embodiments wherein the lighting fixture 100 is to be flush mounted to a junction box 300, it may be undesirable to use a biasing bracket 240. As should be understood, the halo/WAGO/quick connect connector 145 and/or Edison connector may be used in applications regardless of whether or not the embodiment includes a biasing bracket 240 or not.
IV. Exemplary Methods of Installing a Lighting Fixture 100
FIG. 10 provides a flowchart of various processes and operations that may be completed to install a lighting fixture 100 by mounting the lighting fixture to junction box 300. In various embodiments, it may be necessary to cut an appropriately sized hole in a wall, ceiling, and/or the like (e.g., in the drywall, etc. to access the junction box). At step 602, the mounting bracket 200 may be secured to the junction box 300. For example, screws may be used to secure the mounting bracket 200 to the junction box 300 via the attachment elements 210, 310. At step 604, the appropriate electrical connections may be made. For example, the connecting wires 140 may be connected to input (e.g., line voltage) wires 340 via wire nuts 345, a quick connect connector, and/or the like. At step 606, the lighting fixture 100 may be secured to the mounting bracket. For example, the twist and lock element 130 may be received by the twist and lock receiver 230 (e.g., the tabs 135 may be placed within the twist and lock tab receivers 235). The lighting fixture 100 may then be rotated with respect to the mounting bracket 200 to secure the lighting fixture to the mounting bracket 200.
FIG. 11 provides a flowchart of various processes and operations that may be completed to install a lighting fixture 100 by mounting the lighting fixture into a recessed can or can light. At step 702, the mounting bracket 200 is secured to the biasing bracket 240 (e.g., via screws and/or the like). In other embodiments, the mounting bracket 200 and the biasing bracket 240 may be integrally formed, and thus step 702 may be completed during the manufacturing process.
At step 704, the Edison connector 190 is connected to the lighting fixture 100 via the connecting wires 140, Edison connector wires 192, quick connect connectors 145, 195, wire nuts, and/or the like. The Edison connector 190 may be connected to the lighting fixture 100 such that the connecting wires 140 and/or the Edison connector wires 192 pass through the wire conduit 250 and/or through the twist and lock receiver 230 opening in the mounting bracket 200, as shown in FIGS. 7-8. At step 706, the mounting bracket 200 may be secured to the lighting fixture 100. For example, the twist and lock element 130 may be received by the twist and lock receiver 230 (e.g., the tabs 135 may be placed within the twist and lock tab receivers 235). The lighting fixture 100 may then be rotated with respect to the mounting bracket 200 to secure the lighting fixture to the mounting bracket 200.
At step 708, the Edison connector 190 may be secured into the socket of the recessed can light. For example, the Edison connector 190 may be rotated with respect to the socket of the recessed can light such that the Edison connector 190 provides electrical communication between the lighting fixture 100 and line voltage, and/or the like. At step 710, the lighting fixture is secured to the recessed can light. For example, the first resilient members 245 may be pinched together and inserted into the recessed can light. The first resilient members 245 may then bias against and/or grip the interior walls of the recessed can light and/or the receiving features of the can light, holding the lighting fixture 100 to the recessed can light.
The installation methods illustrated in FIGS. 10 and 11 provide non-limiting examples of how the mounting bracket 200 and/or the biasing bracket 240 may be used to install a lighting fixture 100. For example, the mounting bracket 200 may be used to secure a lighting fixture 100 to a junction box. In another example, a mounting bracket 200 and a biasing bracket 240 may be used to secure a lighting fixture 100 to a recessed can light. A variety of other methods of installing a lighting fixture via a mounting bracket 200 may be envisioned as within the scope and spirit of the present inventive concept.
