BACKGROUND

[001] Track lighting systems provide significant flexibility when designing a space’s illumination. Track lighting allows for selectably positioning light modules such as light fixtures, pendants, etc. and for precisely directing illumination from the light modules to the space. This flexibility allows for adjustment according to the particular needs of the space to be illuminated.

[002] A typical track lighting system comprises a track and lighting modules. Tracks support power distribution to and mechanical installation of the lighting modules anywhere along the track.

[003] Even after installation, track lighting systems allow flexibility in making changes according to changes in lighting requirements. For example, light modules may be moveable along the track and/or re-orientable relative to the track. In some track lighting systems, lighting modules may be removed, added, and/or exchanged from the track according to need.

[004] The visual impact of the lighting system overall comprises the light itself, but also the appearance of the track, the lighting modules, and their integration with their surroundings when mounted to a ceiling, wall, and/or other support member.

Conventional track lighting systems are installed on the surface of the ceiling, wall, etc., which may distract from or negatively affect the esthetics of a space.

[005] Moreover, conventional track lighting systems may involve locking

mechanisms between track and lighting module that require extensive manipulation by a user, tools, and/or are just not convenient to install, remove, or adjust. Conventional track lighting locking mechanisms may also make the track lighting overly costly.

[006] Therefore, there is a need in the field for improvements to the conventional track lighting system to make it more convenient, widely available, and cost-effective.

SUMMARY OF THE INVENTION

[007] The present disclosure provides a system including a mounting assembly and track for installation of power modules. The track may be installed flush with a ceiling to minimize distraction and/or negative effect on the esthetics of the illuminated space. Moreover, the locking mechanisms disclosed herein to secure the powered module to the track requires no tools and only minimum manipulation by a user and is, thus, convenient to install, remove, or adjust. In addition, the system disclosed herein provides safe and secure mechanical and electrical connection between the powered module and the track while keeping the system convenient and cost-effective.

appreciated that the illustrated element boundaries (e.g., boxes, groups of boxes, or other shapes) in the figures represent one example of the boundaries. One of ordinary skill in the art will appreciate that one element may be designed as multiple elements or that multiple elements may be designed as one element. An element shown as an internal component of another element may be implemented as an external component and vice versa. Furthermore, elements may not be drawn to scale.

DETAILED DESCRIPTION

[0016] T rack System

[0017] Figures 1 A and 1 B illustrate perspective views of a system 1 for mechanical and electrical engagement of a powered module PM to a ceiling DW. The powered module PM may be any module that receives power (AC or DC) to operate such as, for example, a light fixture, a speaker, a wi-fi router or repeater, a smoke detector, etc. As described below, the system 1 provides convenient installation of the powered module PM to the ceiling DW. Figure 1A illustrates the system 1 in the inserting position while figure 1 B illustrates the system 1 in the locked or connected position. The system 1 includes a track 10 and a mounting assembly 20.

[0018] Track

[0019] The track 10 may include an upper rail 11 , electrode rails 12, 13, and locking rails 14. The track 10 may also include side walls 15 connecting the upper rail 11 , the electrode rails 12,13, and the locking rails 14. In the example of figures 1 A and 1 B, the track 10 includes two sets of electrode rails 12, 13. In other embodiments (not shown), the track 10 may include one set of electrode rails 12, 13 or more than two sets of electrode rails 12, 13.

[0020] The electrode rails 12, 13 may have electrodes 16, 17 coupled or formed thereon. The electrodes 16, 17 are elongated conductors (e.g., copper, aluminum, etc.) that extend most of the length of the corresponding rail. For example, a first electrode rail 12 may have coupled or formed thereon a positive electrode 16 extending most of the length of the rail 12 while a second electrode rail 13 may have coupled or formed thereon a negative electrode 17 extending most of the length of the rail 13. In the example of figures 1A and 1 B, each of the electrode rails 12, 13 has one electrode 16, 17 coupled or formed thereon. In other embodiments (not shown), each of the electrode rails 12, 13 may include more than one electrode 16, 17 coupled or formed thereon. [0021] In the example of figures 1A and 1 B, the first electrode rails 12 have coupled or formed thereon electrodes 16 on a top surface 12a of the rails 12. Similarly, in the example of figures 1A and 1 B, the second electrode rails 13 have coupled or formed thereon electrodes 17 on a top surface 13a of the rails 13. In other embodiments (not shown), the first electrode rails 12 may have coupled or formed thereon electrodes 16 on a bottom surface 12b of the rails 12 or on both the top surface 12a and bottom surface 12b. Similarly, the second electrode rails 13 may have coupled or formed thereon electrodes 17 on a bottom surface 13b of the rails 13 or on both the top surface 13a and bottom surface 13b.

[0022] The track may also include a ground conductor 18 disposed on a bottom surface 11 a of the upper rail 11. Like the electrodes 16, 17, the ground conductor 18 may be an elongated conductor (e.g., copper, aluminum, etc.) that extends most of the length of the upper rail 11. The ground conductor 18 may be installed or formed near the center of the bottom surface 11 a of the upper rail 11.

[0023] The electrodes 16, 17, and the ground conductor 18 may be connected to a circuit such as, for example, a power circuit that may include a switch or dimmer to operate or control a powered module to be installed to the track 10. The electrodes 16, 17 may also correspond to, for example, positive and negative signals of an audio stereo output, etc.

[0024] The track 10 may also include mounting brackets 19 to attach the track 10 to, for example, a ceiling joist or other ceiling structure using bolts or another type of fastener. The locking rails 14 may extend outwardly from the walls 15 into flanges 14a. The track 10 may be installed substantially flush with a ceiling surface. The main body of the track 10 (including the upper rail 11 , electrode rails 12, 13, and the side walls 15) may be inserted in a channel formed on the ceiling and the flanges 14a may overlap a portion of, for example, a drywall board DW which forms part of the ceiling.

[0025] In-Junction-Box System

[0026] Figures 2A-2C illustrate views of an exemplary system 41 for mechanical and electrical engagement of a powered module PM to a junction box JB. As described above, the powered module PM may be any module that receives power (AC or DC) to operate such as, for example, a light fixture, a speaker, a wi-fi router or repeater, a smoke detector, etc. As described below, the system 41 provides convenient installation of the powered module PM to the junction box JB. For illustrative purposes, figures 2A and 2B illustrate the system 41 uninstalled or exploded away from the junction box JB. The system 41 includes an in-junction-box assembly 50 and the mounting assembly 20.

[0027] In-Junction-Box Assembly

[0028] Figure 2C illustrates a perspective view of an exemplary in-junction-box assembly 50. The in-junction-box assembly 50 may include an upper rail 11 , electrode rails 12, 13, and locking rails 14. The in-junction-box assembly 50 may also include side walls 15 connecting the upper rail 11 , the electrode rails 12,13, and the locking rails 14. In the example of figure 2C, the in-junction-box assembly 50 includes two sets of electrode rails 12, 13. In other embodiments (not shown), the in-junction-box assembly 50 may include one set of electrode rails 12, 13 or more than two sets of electrode rails 12, 13.

[0029] The electrode rails 12, 13 may have electrodes 16, 17 coupled or formed thereon. The electrodes 16, 17 are conductors (e.g., copper, aluminum, etc.) disposed on the corresponding rail. For example, a first electrode rail 12 may have coupled or formed thereon a positive electrode 16 while a second electrode rail 13 may have coupled or formed thereon a negative electrode 17. In the example of figure 2C, each of the electrode rails 12, 13 has one electrode 16, 17 coupled or formed thereon. In other embodiments (not shown), each of the electrode rails 12, 13 may include more than one electrode 16, 17 coupled or formed thereon.

[0030] In the example of figure 2C, the first electrode rails 12 have coupled or formed thereon electrodes 16 on a top surface 12a of the rails 12. Similarly, in the example of figure 2C, the second electrode rails 13 have coupled or formed thereon electrodes 17 on a top surface 13a of the rails 13. In other embodiments (not shown), the first electrode rails 12 may have coupled or formed thereon electrodes 16 on a bottom surface 12b of the rails 12 or on both the top surface 12a and bottom surface 12b. Similarly, the second electrode rails 13 may have coupled or formed thereon electrodes 17 on a bottom surface 13b of the rails 13 or on both the top surface 13a and bottom surface 13b.

[0031] The in-junction-box assembly 50 may also include a ground conductor 18 disposed on a bottom surface 11 a of the upper rail 1 1. Like the electrodes 16, 17, the ground conductor 18 may be a conductor (e.g., copper, aluminum, etc.) disposed on the upper rail 11. The ground conductor 18 may be installed or formed near the center of the bottom surface 11 a of the upper rail 11.

[0032] The electrodes 16, 17, and the ground conductor 18 may be connected to a circuit such as, for example, a power circuit that may include a switch or dimmer to operate or control a powered module to be installed to the in-junction-box assembly 50. The electrodes 16, 17 may also correspond to, for example, positive and negative signals of an audio stereo output, etc. In the example of figure 2C, the in-junction-box assembly 50 includes electrical terminals 56 and 57 for receiving electrical wire. The electrical terminals 56 and 57 may be operably connected to the electrodes 16 and 17, respectively. In one embodiment, the in-junction-box assembly 50 includes one or more ground terminals for receiving electrical wire. The one or more ground terminals may be operably connected to the ground conductor 18.

[0033] The in-junction-box assembly 50 may also include mounting brackets 59 to attach the in-junction-box assembly 50 to the junction box JB. In the illustrated embodiment, the mounting brackets 59 are flanges that extend radially away from a center axis a of the in-junction-box assembly 50. The mounting brackets 59 may have formed thereon mounting holes 60 to mount the in-junction-box assembly 50 to the junction box JB. using screws, bolts or another type of fastener. In one embodiment, the locking rails 14 may extend outwardly from the walls 15 into the flanges that form the mounting brackets 59.

[0034] As shown in figure 2B, the main body of the in-junction-box assembly 50 (including the upper rail 11 , electrode rails 12, 13, and the side walls 15) may be inserted in the junction box JB and the mounting holes 60 may align with mounting holes JBh of the junction box JB. Once the in-junction-box assembly 50 is inserted in the junction box JB, the assembly 50 may be secured to the junction box JB using screws, bolts or another type of fastener inserted through the mounting holes 60 and screwed to the holes JBh of the junction box JB. Electrical connections may be made using the electrical terminals 56 and 57.

[0035] Mounting Assembly

[0036] Figures 3-7, in addition to figures 1 A-2B, illustrate the mounting assembly 20. The mounting assembly 20 may be attached to or form part of a powered module PM. The mounting assembly 20 provides mechanical and electrical engagement of the powered module PM to the track 10 or in-junction-box assembly 50 and, thus, to the ceiling. The mounting assembly 20 may include a column or stem 21 and a base 22 operably coupled to the powered module PM. In the illustrated embodiment, the stem 21 has a rectangular cross-section. In other embodiments, the stem 21 may have cross- sections different from rectangular such as circular, etc.

[0037] In figure 3 the mounting assembly 20 is shown in a similar position as in figure 1A. In figure 4 the mounting assembly 20 is shown rotated about 130 degrees for illustrative purposes. The mounting assembly 20 may also include electrode arms 23,

24 extending perpendicularly from the stem 21. Figure 5 illustrates a magnified view of the mounting assembly 20 to show details of the electrode arms 23, 24. In figure 5, the mounting assembly is in a similar position as in figure 4. In the illustrated embodiment, a first electrode arm 23 extends perpendicularly from a first side of the stem 21 while a second electrode arm 24 extends perpendicularly from an opposite side of the stem 21. In the illustrated embodiment, the mounting assembly 20 includes two sets of electrode arms 23, 24. In other embodiments (not shown), the mounting assembly 20 may include one set of electrode arms 23, 24 or more than two sets of electrode arms 23, 24.

[0038] The electrode arms 23, 24 may have coupled to or formed thereon electrodes 25, 26. The first electrode 25 is disposed on the first electrode arm 23 to form or to have a first incline surface 25a. Similarly, the second electrode 26 is disposed on the second electrode arm 24 to form or to have a second incline surface 26a. While in the illustrated embodiments, the first and second incline surfaces 25a, 26a are shown as flat surfaces, in other embodiments the first and second incline surfaces 25a, 26a may be curved surfaces that nonetheless are inclined or ramped. The electrodes 25, 26 are conductors (e.g., copper, aluminum, etc.) that extend at least some of the length of the corresponding electrode arm 23, 24. For example, a first electrode arm 23 may have coupled or formed thereon a positive electrode 25 while a second electrode arm 24 may have coupled or formed thereon a negative electrode 26. In the illustrated embodiment, each of the electrode arms 23, 24 has one electrode 25, 26 coupled or formed thereon. In other embodiments (not shown), each of the electrode arms 23, 24 may include more than one electrode 25, 26 coupled or formed thereon.

[0039] In the illustrated embodiment, the electrodes 25, 26 are coupled or formed on the bottom of the electrode arms 23, 24. In other embodiments (not shown), the electrodes 25, 26 may be coupled or formed on the top of the electrode arms 23, 24 or on both the top and bottom of the electrode arms 23, 24. The electrodes 25, 26 are intended to electrically engage the electrodes 16, 17 of the track 10 or in-junction-box assembly 50 to provide positive and negative electrical connections, respectively, to the powered module PM.

[0040] The mounting assembly 20 may also include locking arms 27, 28 extending perpendicularly from the stem 21. Figure 6, in addition to figures 1 -5, illustrate the locking arms 27, 28. Figure 6 illustrates a magnified view of the mounting assembly 20 to show details of the locking arms 27, 28. In figure 6, the mounting assembly is a similar position as in figures 4 and 5. In the illustrated embodiment, a first locking arm 27 extends perpendicularly from a first side of the stem 21 while a locking arm 28 extends perpendicularly from an opposite side of the stem 21. The locking arms 27, 28 have formed thereon decline surfaces 27a, 28a. While in the illustrated embodiments, the first and second decline surfaces 27a, 28a are shown as flat surfaces, in other embodiments the first and second decline surfaces 27a, 28a may be curved surfaces that nonetheless are declined or ramped.

[0041] Notice, particularly in figures 1 and 3, that a plane of the first incline surface 25a intersects a plane of the first decline surface 27a. Similarly, as best shown in figure 4, a plane of the second incline surface 26a intersects a plane of the second decline surface 28a. As described in more detail below, this characteristic of the incline surfaces 25a, 26a relative to the decline surfaces 27a, 28a allows the mounting assembly 20 to be easily insertable in the track 10 or in-junction-box assembly 50 and securely mechanically and electrically engageable to the track 10 or in-junction-box assembly 50.

[0042] The mounting assembly 20 may also include a ground arm 29 extending from the top of the stem 21 distal the base 22. Figure 7 illustrates a magnified view of the ground arm 29. The ground arm 29 may have coupled or formed thereon a ground electrode or ground contact 30. The ground contact 30 may be a conductor (e.g., copper, aluminum, etc.) and it is intended to electrically engage the ground conductor 18 of the track 10 or in-junction-box assembly 50 to provide a ground connection to the powered module PM. The ground contact 30 may be elastically connected to the ground arm 29 extending from the top of the stem 21. In one embodiment, the mounting assembly 20 includes a spring disposed between the ground electrode 30 and the distal end 29. In other embodiments, the ground contact 30 may be elastically connected to the ground arm 29 by other elastic means such as, for example, an elastomer, etc. In one embodiment, the ground contact 30 is not elastically connected to the ground arm 29.

[0043] The mounting assembly 20 may also include electrical connections (e.g., wires, printed circuit board, etc.) to electrically connect the electrodes 25, 26 and the ground contact 30 to the powered module PW. For example, the mounting assembly 20 may include electrical terminals at or near the base 22 and electrical connections within the arms 23 and 24, and the stem 21 that electrically connect the electrodes 25, 26 and the ground contact 30 to the electrical terminals. Wiring of the powered module PM may connect to the electrical terminals of the mounting assembly 20 to power the powered module PM.

[0044] Powered Module Installation

[0045] A method of mounting a powered module PM including or having coupled thereon the mounting assembly 20 to a track 10 or in-junction-box assembly 50 would be described now in reference to the figures.

[0046] First, a user may insert the stem 21 in the orientation shown in figure 1 A into the groove or opening G formed between the locking rails 14 and between the electrode rails 12, 13. In the illustrated embodiment, inserting the stem 21 into the groove G until the ground contact 30 contacts the ground conductor 18 results in the electrode arms 23, 24 being simultaneously inserted into the groove G while the locking arms 28 remain uninserted into the groove G.

[0047] If using the track system 1 , at this point, the user may slide the powered module PM to a desired position along the track 10.

[0048] The user may then rotate the powered module PM clockwise for the incline surfaces 25a, 26a of the electrodes 25, 26 of the mounting assembly 20 to engage the electrodes 16, 17 of the track 10 or in-junction-box assembly 50. In the illustrated embodiment, the incline and decline surfaces are disposed such that clockwise rotation locks the mounting assembly 20 to the track 10 or in-junction-box assembly 50. In other embodiments, the incline and decline surfaces may be disposed such that counter clockwise rotation of the powered module PM result in locking of the mounting assembly 20 to the track 10 or in-junction-box assembly 50. In the illustrated embodiment, this clockwise rotation of the powered module PM simultaneously causes engagement of the decline surfaces 27a, 28a of the locking arms 27, 28 of the mounting assembly 20 to bottom sides 14b of the locking rails 14 of the lighting track 10 or in-junction-box assembly 50.

[0049] Simultaneous pressure of the incline surfaces 25a, 26a against the electrodes 16, 17 and of the decline surfaces 27a, 28a against the bottom sides 14b of the locking rails 14 mechanically creates a locking, spring-like, effect of the mounting assembly 20 to the track 10 or in-junction-box assembly 50. This simultaneous pressure also provides adequate electrical connection between the electrodes 25, 26 and the electrodes 16, 17. In one embodiment, the incline surfaces 25a, 26a and/or the decline surfaces 27a, 28a may include a particularly sharp edge to bite into the electrodes 16,

17 and/or the bottom sides 14b of the locking rails 14, respectively, to provide an additional locking effect. Finally, this arrangement results in adequate electrical connection between the ground contact 30 and the ground conductor 18, particularly if the ground contact 30 is elastically connected to the ground arm 29.

[0050] In one embodiment, the mounting assembly 20 may not include the locking arms 27, 28 and, instead, the system 1 may rely on simultaneous pressure of the incline surfaces 25a, 26a against the electrodes 16, 17 and of the ground contact 30 against the ground conductor 18. In this embodiment, the ground arm 29 acts as a locking arm and the ground contact 30 as locking surface. Notice that planes of the incline surfaces 25a, 26a intersect a plane of the ground contact or locking surface 30 resulting in elastic repulsive pressure when the mounting assembly 20 is inserted in the groove G and rotated clockwise. This elastic repulsive pressure not only results in adequate electrical connection between the ground contact 30 and the ground conductor 18 but also creates a locking spring-like effect of the mounting assembly 20 to the track 10 or in- junction-box assembly 50. Thus, this simultaneous pressure may also provide adequate electrical connection between the electrodes 25, 26 and the electrodes 16, 17. This pressure may be particularly controllable in an embodiment in which the ground contact 30 is elastically (e.g., spring loaded) connected to the ground arm 29. In one

embodiment, the incline surfaces 25a, 26a may include a particularly sharp edge to bite into the electrodes 16, 17 to provide an additional locking effect.

[0051] Removal or reinstallation of a powered module PM is just as convenient. The user may rotate the powered module in the opposite direction (e.g., counter-clockwise in the illustrated embodiment) to disengage the incline surfaces 25a, 26a of the electrodes 25, 26 of the mounting assembly 20 from the electrodes 16, 17 of the track 10 or in- junction-box assembly 50. This rotation also disengages the decline surfaces 27a, 28a from the bottom 14b of the bottom rail 14. The user may rotate the powered module PM until the mounting assembly 20 is oriented in the inserted position as shown in figure 1A. The user may then simply remove the power module PM from the track 10 or slide the power module PM to any desired position along the track 10 for installation at that new position. Similarly, the user may then simply remove the power module PM from the in-junction-box assembly 50.

[0052] DEFINITIONS

[0053] The following includes definitions of selected terms employed herein. The definitions include various examples or forms of components that fall within the scope of a term and that may be used for implementation. The examples are not intended to be limiting. Both singular and plural forms of terms may be within the definitions. [0054] As used herein, an“operable connection” or“operable coupling,” or a connection by which entities are“operably connected” or“operably coupled” is one in which the entities are connected in such a way that the entities may perform as intended. An operable connection may be a direct connection or an indirect connection in which an intermediate entity or entities cooperate or otherwise are part of the connection or are in between the operably connected entities. In the context of signals, an“operable connection,” or a connection by which entities are“operably connected,” is one in which signals, physical communications, or logical communications may be sent or received. Typically, an operable connection includes a physical interface, an electrical interface, or a data interface, but it is to be noted that an operable connection may include differing combinations of these or other types of connections sufficient to allow operable control. For example, two entities can be operably connected by being able to communicate signals to each other directly or through one or more intermediate entities like a processor, operating system, a logic, software, or other entity. Logical or physical communication channels can be used to create an operable connection.

[0055] To the extent that the term“includes” or“including” is employed in the detailed description or the claims, it is intended to be inclusive in a manner similar to the term“comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term“or” is employed in the detailed description or claims (e.g., A or B) it is intended to mean“A or B or both”. When the applicants intend to indicate“only A or B but not both” then the term“only A or B but not both” will be employed. Thus, use of the term“or” herein is the inclusive, and not the exclusive use. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995).

[0056] While example systems, methods, and so on, have been illustrated by describing examples, and while the examples have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit scope to such detail. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the systems, methods, and so on, described herein. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention is not limited to the specific details, the representative apparatus, and illustrative examples shown and described. Thus, this application is intended to embrace alterations, modifications, and variations that fall within the scope of the appended claims. Furthermore, the preceding description is not meant to limit the scope of the invention. Rather, the scope of the invention is to be determined by the appended claims and their equivalents.
