The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventor, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
A first lighting arrangement can include a canopy, a pendant, a first wire member, a second wire member, and a quick connect assembly. The canopy can be operable to be mounted to a ceiling and can have a first fastener. The pendant can include a light, a supporting cable connected to the light, and a second fastener connected to the supporting cable. The second fastener can be releasibly engageable with the first fastener. The first wire member can extend through the canopy to a first end. The second wire member can be in electrical communication with the light and extend through the supporting cable to a second end. The quick connect assembly can include a first quick connect member attached to the first end and a second quick connect member attached to the second end. The first quick connect member and the second quick connect member can be releasibly engageable with respect to one another and configured to define an electrical pathway between the first wire member and the second wire member when engaged with one another.
A second lighting arrangement can include a canopy, a pendant, and a wire member assembly. The canopy can be operable to be mounted to a ceiling and can have a first fastener. The pendant can include a light with a plurality of light emitting diodes, a supporting cable connected to the light, and a second fastener connected to the supporting cable. The second fastener can be releasibly engageable with the first fastener. The wire member assembly can extend through the canopy and the supporting cable to a light. The wire member assembly can be configured to transmit one hundred volts and five amps.
The detailed description set forth below references the following drawings:
The present disclosure, as demonstrated by the exemplary embodiment described below, can provide a quick connect pendant to canopy lighting arrangement. This lighting arrangement allows users to first install a canopy to the ceiling and subsequently install one or more pendants. After the pendant is connected to the canopy, a user can adjust the pendant to a desired length. Embodiments of the present disclosure can be practiced with single pendants and multiple pendants. Further, if a pendant becomes faulty or undesirable, the user can disconnect the pendant from the canopy and install another, different pendant. Most known arrangements require a user to remove the entire lighting arrangement, which is time consuming and costly. Other systems may allow a pendant to be installed after the canopy has been installed onto the ceiling, but none have the capacity for wire adjustment.
Further, embodiments of the present disclosure provide a Solid State Light (hereafter “SSL”) wire member configured to transmit one hundred and twenty volts, five amps. The wire member can include twenty-four Gauge wire. The wire member disclosed herein is small and yet conforms to the UL 758 standard for wiring. The wire member can thus provide a sleeker look and design to the lighting arrangement.
As illustrated in
The canopy 12 can also include a shell 28 and a first fastener 30. The shell 28 can include an outer surface 32 with a first aperture 34. The shell 28 can define a cavity 36. The first fastener 30 can be a threaded mounting ring having a second aperture 38. Threads are referenced at 40. The first fastener 30 can be positioned in the cavity 36 such that the second aperture 38 is aligned with the first aperture 34.
The pendant 14 can include a light 42, a supporting cable 44 connected to the light 42, and a second fastener 46 connected to the supporting cable 44. The light 42 can include with a plurality of light emitting diodes, such as light emitting diodes 48, 50. The supporting cable 44 can be connected to the light 12 and mechanically support the light 42 when the light 42 is suspended.
The second fastener 46 can be connected to the supporting cable 44 and releasibly engageable with the first fastener 30. The exemplary second fastener 46 can include a first threaded mounting ring 52 and a second threaded mounting ring 54. The first threaded mounting ring 52 can include external threads 56 configured to engage the threads 40 of the first fastener 30. The first threaded mounting ring 52 can also include internal threads (not visible).
The second threaded mounting ring 54 can include external threads 58 configured to engage the internal threads of the first threaded mounting ring 52. The first threaded mounting ring 52 and the second threaded mounting ring 54 are thus threadingly engageable with one another. Similarly, the second fastener 46 can be releasibly engageable with the first fastener 30 through the threads 40 and 56. The engagement with threads allows the first fastener 30 and the second fastener 46 to be adjustably positioned with respect to one another. Similarly, the engagement with threads allows the first threaded mounting ring 52 and the second threaded mounting ring 54 to be adjustably positioned with respect to one another. As result, the height of the pendant 14 can be varied among a plurality of different positions.
Each of the first threaded mounting ring 52 and the second threaded mounting ring 54 can include an aperture. The internal threads of the first threaded mounting ring 52 can be formed in at least a portion of an aperture 60 of the first threaded mounting ring 52. The aperture of the second threaded mounting ring 54 is not visible in the Figures.
The first wire member 16 can extend through the canopy 12 to a first end 62. The first wire member 16 can be anchored to the interior of the canopy 12, within the cavity 36. The second wire member 18 can be in electrical communication with the light 42 and extend through the supporting cable 44 to a second end 64. The first wire member 16 can pass through the aperture 38 of the first fastener 30. The second wire member 18 can pass through both of the apertures of the first threaded mounting ring 52 and the second threaded mounting ring 54. The first and second wire members 16, 18 can form part of a wire member assembly 66. The connection assembly 20 can bifurcate the wire member assembly 66 into the first wire member 16 and the second wire member 18.
The first wire member 16 can also include a second wire assembly 74 having a second wire 76 enclosed in a second insulating sheath 78. The second wire 74 can be the neutral wire of the lighting arrangement 10. The first wire member 16 can also include a third insulating sheath 80 enclosing both of the first wire assembly 68 and the second wire assembly 74. The first wire member 16 can also include a ground wire 82 encircling the third insulating sheath 80. The ground wire 82 can be braided. The first wire member 16 can also include a fourth insulating sheath 84 enclosing the ground wire 82.
The quick connect assembly 20 can include a first quick connect member 86 attached to the first end 62 of the first wire member 16. The quick connect assembly 20 can also include a second quick connect member 88 attached to the second end 64 of the second wire member 18. The first quick connect member 86 and the second quick connect member 88 can be releasibly engageable with respect to one another. The first quick connect member 86 and the second quick connect member 88 can be configured to define an electrical pathway between the first wire member 16 and the second wire member 18 when engaged with one another.
The first quick connect member 86 can include embedded electrical contacts and define three receiving apertures, such as aperture 90 referenced in
The first quick connect member 86 and the second quick connect member 88 can be releasibly fixed together through a snap-lock arrangement. The second quick connect member 88 can include a locking arm 94. During insertion of the engaging projections of the second quick connect member 88 in the apertures of the first quick connect member 86, a forward face 96 of the locking arm 94 can ride up a ramp 98 of the first quick connect member 86 and deflect. After a forward portion 100 of the locking arm 94 traverses the ramp 98, the locking arm 94 can snap back and recover, such that a rear face 102 of the forward portion 100 abuts a rear face 104 of the ramp 98. When it is desired to decouple the first quick connect member 86 and the second quick connect member 88, the locking arm 94 can be deflected back and the first quick connect member 86 and the second quick connect member 88 can be pulled apart.
The quick connect assembly 20 is at least partially received in the aperture 38 of the first fastener 30. The quick connect assembly 20 can be sized smaller than the second aperture 38 and can be configured to pass through the second aperture 38 of the first fastener 30. The quick connect assembly 20 can thus be at least partially positionable within the canopy 12. The quick connect assembly 20 can be sized to pass through only the threaded mounting ring 30 in some embodiments. The quick connect assembly 20 can be sized larger than the apertures of the second fastener 46.
In operation, the first wire member 16 can be spliced to electrical wires in the junction box 26. The plate 24 can then be installed to the junction box 26. The first wire member 16 can then be strung through the plate 24, the canopy 12, and the first fastener 30. The canopy 12 can then be mounted on the ceiling 22. The first quick connect member 86 and the second quick connect member 88 can then be coupled and urged into the cavity 36 of the canopy 12. The first threaded mounting ring 52 and the second threaded mounting ring 54 can then be threadingly engaged together. The first threaded mounting ring 52 and the first fastener 30 can then be threadingly engaged together. The height of the pendant 14 can then be adjusted by rotating the first threaded mounting ring 52 relative to the first fastener 30 and/or by rotating the second threaded mounting ring 54 relative to the first threaded mounting ring 52.
