TECHNICAL FIELD
Embodiments of the present disclosure relate generally to lighting solutions, and more particularly to systems, methods, and devices for providing a hinged mounting solution in a luminaire for quick installation.
BACKGROUND
Previous designs of light fixtures that incorporate rotatable LED-based light modules often include wiring layouts that are internal to the light fixture housing. This often limits the range of movement of the light modules and wiring integrity of the light fixture. For example, an operator changing the angle of the light modules may have to be extra careful when handling the light fixture so as not to accidentally pull or otherwise disrupt the wiring between the light modules and the other electronic components of the light fixture. Furthermore, such light fixtures are often mounted on a ceiling or other mounting structure, through which the light fixture is also electrically wired. During installation or maintenance, the light fixture may need to be removed from the ceiling in order to access the wires or other installation interface on the back side of the light fixture. In such cases, the operator may need to support the light fixture while performing the operation, making the process more challenging and error prone. Thus, what is needed is a light fixture that allows for wiring the rotatable modules in such a way as to allow for rotation of the module while reducing the size or necessary layout of a fixture housing yet maintain wiring integrity and electrical reliability for the rotatable module. Additionally, the light fixture should provide a mounting means that allows for easy accessibility of the light fixture.
SUMMARY
An example embodiment of the present disclosure includes a light fixture. The light fixture includes a central housing containing one or more electrical components, a central grommet, wherein the central grommet traverses a central opening in the central housing, providing a path for a central cord to enter the central housing through the grommet, wherein the central grommet forms a water tight seal between the central cord and the central housing, and wherein the central cord is electrically coupled to the one or more electrical components. The light fixture further includes at least one rotatable light module coupled to the central housing, the at least one rotatable light module comprising a heat sink on a heat sink side of the at least one rotatable light model, and at least one peripheral cord coupled to the at least one rotatable light module at a first end of the at least one peripheral cord and traversing at least one respective peripheral opening in the central housing, wherein the at least one peripheral cord is electrically coupled to the one or more electrical components and the rotatable light module.
Another example embodiment of the present disclosure includes a mounting assembly. The mounting assembly includes a top plate having a first mating mechanism, a support hanger having a first end and a second end, the first end rotatively coupled to the top plate. The mounting assembly also includes a bottom plate comprising a second mating mechanism corresponding to the first mating mechanism, wherein the second end of the support hanger is rotatively coupled to the bottom plate. The mounting assembly is foldable into a folded position and extendable into an extended position. In the folded position, the bottom plate, the support hanger, and the top plate are substantially parallel, and wherein the bottom plate is coupled to the top plate via the first and second mating mechanisms, the bottom plate being a first distance from the top plate. In the extended position, the first mating mechanism is decoupled from the second mating mechanism, the bottom plate being a second distance from the top plate, the second distance being greater than the first distance, and wherein the bottom plate is supported by the top plate via the support hanger.

BRIEF DESCRIPTION OF EXAMPLE EMBODIMENTS
Embodiments of the disclosure are directed to the construction and assembly of a light fixture with rotatable light modules and hinged mounting assembly. Example embodiments of the disclosure include flexible cords accessible on the outside of the light fixture housing to act as a strain relief to prevent internal wiring damage due to pulling of the flexible cord. The systems and methods described herein may provide several advantages including providing a strain relief to prevent the flexible cord from being pulled out of the light module (such as an LED-based light module) during transport, installation, or in the event the fixture was disturbed or vandalized. The embodiments of the disclosure described herein include other benefits such as providing a water tight flexible cord and grommet assembly to prevent water from entering the light module between the flexible cord and an overmolded grommet. Another benefit of certain embodiments of the disclosure is that when the light module is rotated, the integrity of the flexible cord entry into the back of the light module (or the heat sink of the light module) remains uncompromised. Embodiments described herein also include a snap and lock hinge mount for securing the light fixture to a ceiling or wall while allowing for easy access and installation.
Example embodiments of the disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of the disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like numbers refer to like, but not necessarily the same or identical, elements throughout.
FIG. 1A is a light fixture 100 having rotatable light modules 105 and a snap and lock hinge mount 115 in accordance with an example embodiment of the disclosure. As shown in FIG. 1A, the light fixture 100 includes a central housing 110. The central housing 110 may house internal components of the light fixture, such as a driver module, backup battery, sensor(s), controller(s), wiring splices or junctions, etc. The main power line wiring 160 enters the central housing 110 in the middle of a top surface 111 of the central housing 110. As shown in FIG. 1A, the top surface 111 of the central housing 110 has a mounting assembly 115 attached. In the example embodiment shown in FIG. 1A, a grommet 125 and a cord 130 are located in the middle of each side 112 of an upper portion 165 of the central housing 110. The grommet 125 and cord 130 shield electrical conductors (e.g. wire, etc.) being routed from the central housing 110 to the light modules 105. In other embodiments of the disclosure, the grommet 125 and cord 130 may be located elsewhere along the exterior of the central housing 110 (i.e. other than the middle of each side of the central housing). Each cord 130 attaches to the light module 105, which in the embodiment shown in FIG. 1A, occurs in the middle of the light module 105 and is supported by a bracket assembly 120 and another grommet (not shown). In other embodiments of the disclosure, the cord 130 may be connected to the light module 105 elsewhere along the heat sink 135 or other surface of the light module 105 (i.e. other than the middle of the back of the heat sink 135 of the light module 105).
The light fixture 100 further includes one or more thin corner sections 105 extending from corners of the central housing 110. The light modules 105 are disposed between the thing corner sections 155 at the sides 112 of the light fixture. In certain example embodiments, and as illustrated in FIG. 1A, the light module 105 is attached to the thin corner sections 145 at one or more ends. The thin corner sections 145 include a slot 150 which defines a range of rotation for the light module 105. A pin (or screw or similar protrusion) 155 engages the slot 150 and the light module 105 to provide rotation for the light module 105 and hold (or lock) the light module 105 in place at a particular angle to direct light from the module 105 in a particular direction or configuration. The light module 105 includes a heat sink 135 and an LED board 140 (or substrate) thermally coupled to the heat sink 135.
FIG. 1B is an exploded view of the light fixture of FIG. 1A in accordance with an example embodiment of the disclosure. As shown in FIG. 1B, the central housing 110 is made up of a top portion 165 and a bottom portion 170. The housing 110 encloses/houses one or more internal components 175 such as a driver, backup battery, etc. FIG. 1B also shows the mounting assembly 115 for suspending the fixture from a ceiling. FIG. 1B also provides a better view of the corner section 145 of the housing 110 and how the light module 105 connects to the housing 110 while allowing the module 105 to rotate. In the embodiment shown in FIG. 1B, the top and bottom portions 165, 170 along with the corner sections 145 of the light fixture 100 are made from a deep drawn process using cold rolled steel. Such material allows for an overall lower assembly and manufacturing cost, while maintaining considerable strength as compared to traditional materials used for light fixture housings (e.g. aluminum, die casting, etc.).
FIG. 2 shows a top view of a light module connection assembly 200 in accordance with an example embodiment of the disclosure. As shown in FIG. 2, the light module connection assembly 200 includes a grommet 205 covering an opening from the central housing 110 of the light fixture 100 which allows a cord 210 to pass through and connect to the back of the light module 105 for routing wiring to the LEDs on the LED board/substrate 215 of the light module 105 in such a way that the wiring is protected from water and prevents water from entering the fixture housing 110. The heat sink 225 located on the back of the light module 105 is shaped to accept the cord 210 as well as a bracket assembly 220 surrounding the cord 210. In the embodiment shown in FIG. 2, the bracket assembly 220 provides strain relief for the cord 210 when the cord is handled, pulled, or twisted. Further, the bracket assembly 220 protects the flexible cord 210 entry into the heat sink 225 while helping to prevent water entry into the light module 105. In an alternative embodiment of the disclosure, a grommet may be used on the light module 105 in place of (or in addition to) the bracket assembly 220 to provide similar protection and functionality (e.g. stain relief, etc.) as the bracket assembly 220. In certain example embodiments, the lighting module 105 includes light sources other than LEDs.
FIG. 3 is an exploded view of a bracket assembly 300 used in a light module connection assembly 200, in accordance with an example embodiment of the disclosure. As shown in FIG. 3, the bracket assembly 300 is made up of a first bracket 305 and second bracket 310, each of which has a C-shaped surface profile on one side, such that when the first bracket 305 and second bracket 310 are engaged with one or more fasteners 315 (e.g., a screw, pin, rivet, or other protrusion that may or may not be able to be tightened) the bracket assembly 300 compresses a grommet 320 around the flexible cord 325, making the connection where the flexible cord 325 attaches to the light module water tight. As shown in FIG. 3, an overmold grommet 320 covers the flexible cord 325 attaching to the light module 105.
FIG. 4 is a cross-sectional view 400 of a light module connection assembly 200 in accordance with an example embodiment of the disclosure.
