Embodiments of the invention relate to a junction box housing, and more specifically a retrofit luminaire junction box housing for light emitting diode (LED) recessed fixtures.
Electrical fixtures, such as luminaires, must be adequately supported when installed because a fixture that is improperly supported may break away from the location where it is installed, such as in a ceiling. Ceilings are typically constructed of structural members including a series of spaced apart joists, which are covered by covering material such as drywall. However, the ceiling covering material is typically not designed to support loads such as those imparted by electrical fixtures. Therefore, in order to suspend electrical fixtures from the ceiling, the weight must be supported by the joists. In recessed lighting applications, the luminaire is supported between adjacent joists, but the number and size of components needed for the luminaire may limit when recessed lighting may be used.

Embodiments of the present invention are directed to a junction box housing system and methods of employing the junction box housing for wall or ceiling installation. The junction box housing system may be used with light emitting diode (LED) luminaires, although it will be appreciated that various other types of luminaires (regardless of the light source) may be used. In some embodiments, the junction box housing system may be used for retrofit luminaires, although they need not be. The junction box housing system incorporates the junction box and housing as one unit such that the luminaire may be wired directly in, and allow for easy mounting of a luminaire within the housing in insulated covered applications. In some embodiments, the junction box housing system allows the housing to be adjusted vertically, horizontally, or both horizontally and vertically when the housing is installed between standard joists. In some embodiments, the vertical adjustment may accommodate different ceiling thicknesses in which the junction box housing is installed.

In various examples, the housing 100 may have a substantially circular cross-sectional profile. However, in various other examples, the housing 100 may have various other desired cross-sectional profiles including, but not limited to, square, rectangular, elliptical, angled, octagonal, or various other suitable profiles.

The first hanger 200A includes a first end 202 and a second end 204. As illustrated in
In some embodiments, the first hanger 200A is a unitary component or a combination of components defining a fixed distance between the first end 202 and the second end 204. In other embodiments, the first hanger 200A is adjustable such that a distance from the first end 202 to the second end 204 may be varied. As one non-limiting example, as illustrated in

In various embodiments, the body 302 of the hanger bracket 300 includes a bracket stopper 310. In the present example, the bracket stopper 310 is a stopper tab that may be depressed or deformed to engage the first hanger 200A and secure the hanger bracket 300 at a desired horizontal position along the first hanger 200A. Because the housing 100 may be supported by the hanger bracket 300, securing the hanger bracket 300 at the desired horizontal position along the first hanger 200A also secures the housing 100 at the desired horizontal position along the first hanger 200A. In various examples, the body 302 may optionally define a stopper aperture 306 that is dimensioned to accommodate a housing stopper 114 that secures the housing 100 relative to the hanger 200A, although it need not.

In various examples, the housing 100 of the junction box housing system 10 is attached to the first hanger 200A and the second hanger 200B by inserting the locking tabs 308 of hanger brackets 300 on each of the first hanger 200A and the second hanger 200B into the mounting slots 110A and 110B. In some embodiments, fasteners may be pre-installed in fastener receivers 214 of the first hanger 200A and the second hanger 200B, although they need not be. In the junction box housing system 11, the housing 100 is attached to the first hanger 200A and the second hanger 200B by inserting the first hanger 200A and the second hanger 200B through first mounting apertures 116 and second mounting apertures 118 provided at the first side 122 and the second side 124 of the sidewall 102, respectively.
The housing 100 is placed between a first joist and a second joist. The first hanger 200A and the second hanger 200B are secured to both the first joist and the second joist. In some embodiments, the first hanger 200A and the second hanger 200B are both secured to the first joist before the first hanger 200A and second hanger 200B are secured to the second joist, although they need not be. In various examples, prior to securing the first hanger 200A and the second hanger 200B to the joists, a length of the first hanger 200A and the second hanger 200B may be adjusted to vary the distance between the first end 202 and the second end 204 of the hangers 200A,B.
The housing 100 may be horizontally positioned at a desired location between the first joist and the second joist by moving the housing 100 along the first hanger 200A and the second hanger 200B. In some embodiments, at the desired position along the first hanger 200A and the second hanger 200B, bracket stoppers 310 of the hanger brackets 300 on each of the first hanger 200A and the second hanger 200B are engaged with the first hanger 200A and the second hanger 200B, respectively, to horizontally secure the housing 100. In the junction box housing system 11, housing stoppers 114 at the first and second portions of the sidewall 102 may engage the housing 100 with the first hanger 200A and the second hanger 200B, respectively, to horizontally secure the housing 100. In the junction box housing system 10, the housing stoppers 114 may engage the housing 100 with the first hanger 200A and the hanger bracket 300 on the first hanger 200A, as well as engage the housing 100 with the second hanger 200B and the hanger bracket 300 on the second hanger 200B.
In some embodiments, the housing 100 is vertically adjusted such that the housing 100 is at a desired height relative to the joists. For example, in various embodiments, the housing 100 is vertically adjustable to accommodate different joists and ceilings that have different thicknesses. In various examples, vertically adjusting the housing 100 includes engaging the hanger brackets 300 on each of the first hanger 200A and the second hanger 200B with the first mounting slot 110A and the second mounting slot 110B, respectively, and vertically positioning the hanger brackets 300 within the mounting slots 110A and 110B. In various examples, wiring 400 is inserted through the wiring aperture 120 defined in the housing 100 before installation of the housing 100 or after installation of the housing 100. The luminaire 500 (see
Different arrangements of the components depicted in the drawings or described above, as well as components and steps not shown or described are possible. Similarly, some features and sub-combinations are useful and may be employed without reference to other features and sub-combinations. Examples of the invention have been described for illustrative and not restrictive purposes, and alternative examples will become apparent to readers of this patent. Accordingly, the present invention is not limited to the examples described above or depicted in the drawings, and various examples and modifications may be made without departing from the scope of the claims below.
