     DETAILED DESCRIPTION 
     The present disclosure provides improvements to the current state of the art of lighting fixtures. In particular illustrative embodiments, track lighting is illustrated, although it will be appreciated that certain aspects of the disclosure relate to lighting generally. 
     Applicant has observed that typical track lighting adapters are required to have a mechanical “stop” to ensure the electrical wires inside the adapter are not damaged by over-rotation. However, Applicant also appreciates that such rotation limitations can be found in many types of lighting devices, and not only track lighting. Thus, in accordance with one aspect, the disclosure provides implementations of electrical connectors that permit any desired amount of rotation in a lighting circuit. While this is illustrated with respect to a luminaire for a track lighting system, it will be appreciated that the disclosed implementations can be applied to many types of lighting systems, including lamps and the like. 
     In accordance with further embodiments, the present disclosure provides implementations of improved two-circuit adapters for track lighting systems. In some conventional two-circuit adapters, one of the copper connectors can be set at two different, discrete levels. One level makes electrical contact with the first electrical circuit on the track, the other level makes electrical contact with a second electrical circuit, thus allowing two light switches to control two sets of lights on a single conductive track assembly. Because such an electrical connector needs to have the ability to move up and down, such two-circuit track adapters typically have taller housings. In accordance with the present disclosure, improved adapters with lower profile housings are provided by providing conductors with an adjustable linear length, as set forth herein. While these conductors are particularly illustrated as providing electrical pathways for a live electrical feed, it will be appreciated that such connections can be configured for use with neutral and ground connections, as desired. 
     It will be appreciated that other novel, useful, and non-obvious aspects and embodiments providing additional advantages are provided herein. 
     For purposes of illustration, and not limitation,  FIG.  1    illustrates a top-down perspective view of a left side  130  of a low profile lighting adapter  100  in accordance with the present disclosure. The low profile lighting adapter  100  includes a first housing section  102 , configured with a cut out section to hold an electrical ground connection  110 . The first housing section  102  can be inserted into a second housing section  103 . The second housing section  103  can include a planar surface  131  and an extension  136  orthogonal to the planar surface  131  for coupling with the first housing section  102 . The second housing section  103  also includes holes for receiving screws  101 - 1 ,  101 - 2 ,  101 - 3 , and  101 - 4  (collectively referred to herein as screws  101 ). When coupled, the first housing section  102  and the second housing section  103  can hold neutral electrical connection  111 . Housing  108  can encase the low profile lighting adapter  100 , and connect with an extending arm  106 . The extending arm  106  (shown in full in  FIG.  9    and  FIG.  10   ; partial views are otherwise displayed with the lower end of arm  106  truncated or cut) can be coupled to the housing  108  via a plurality of rings which enable extending arm  106  to rotate about an axis  140  orthogonal to planar surface  131 . The low profile lighting adapter  100  can also include a clip  107  which can extend along axis  140  to lock low profile lighting adapter  100  into a fixed position, such as within a light track. 
       FIG.  2    illustrates a top-down perspective view of a front side  131  of a low profile lighting adapter  100  in accordance with the present disclosure. The low profile lighting adapter  100  can include live electrical connection  112 . The live electrical connection  112  can extend along axis  140  to connect with an electrical power supply, such as provided by a light track. The live electrical connection  112  can be individually actuated, or moved along axis  140 , independent from conductive bracket  150  (shown, for example in  FIG.  13 C ), the electrical ground connection  110 , and neutral electrical connection  111 . 
     In a 2-circuit lighting adapter, one of the copper connectors can be set at two different levels. At one level, the copper connector makes electrical contact with a first electrical circuit on the light track, and the second level makes electrical contact with a second electrical circuit on the light track, thereby allowing two light switches to control two sets of lights on a single light track. In the example illustrated in  FIG.  2   , live electrical connection  112  can be actuated along axis  140  to one position in order to make electrical contact with a first electrical circuit on the light track, and actuate along axis  140  to a second position in order to make electrical contact with a second electrical circuit on the light track. That is, live electrical connection  112  can move to a distal position along axis  140  relative to conductive bracket  150  in order to make electrical contact with a first electrical circuit, and move to a proximal position along axis  140  relative to live bracket  150  in order to make electrical contact with a second electrical circuit. By individually actuating live electrical connection  112 , a lower profile lighting adapter may be achieved because only one electrical component (e.g., live electrical connection  112 ) slides up or down to touch the upper or lower track. 
       FIG.  3    illustrates a top-down perspective of a back side  133  of a low profile lighting adapter  100 , and  FIG.  4    illustrates a side perspective of a right side  132  of the low profile lighting adapter  100 . As illustrated in  FIG.  4   , the first housing section  102  and/or the second housing section  103  can include a cut out portion, or channel, which permits the live lead  112  to slide along axis  140  with respect to bracket  150 , and independently from electrical ground connection  110 , and neutral electrical connection  111 .  FIG.  5    illustrates a side perspective of a front side  131  of the low profile lighting adapter  100 . Because live electrical lead  112  can move along axis  140  independently from bracket  150 , electrical ground connection  110 , and neutral electrical connection  111 , the low profile lighting adapter  100  can have a lower height form factor as compared to lighting adapters in which multiple electrical connections actuate along a longitudinal axis. Bracket can be bowed in an outward radial direction away from the center of the assembly and directly contact housing  102  at each end as set forth in  FIG.  22 B  so as to act as a leaf spring that can deflect downwardly/radially inwardly, as lead  112  slides over it within the outer axial channel of housing  102 . 
       FIG.  6    illustrates a bottom-up perspective of a low profile lighting adapter  100  in accordance with the present disclosure. As illustrated, housing  108  can include a bottom portion  108 - 2  that is disposed along a planar surface  135  and a side portion  108 - 1  which encompasses the low profile lighting adapter  100  in a direction orthogonal to planar surface  135 . Similarly, extending arm  106  can include a first portion  106 - 1  which extends along axis  140 , and a second portion  106 - 2  orthogonal to portion  106 - 1  and configured to rotate in 360 degrees about axis  140  and within housing  108 - 2 . As illustrated, extending arm  106  may have a hollow core and may have a generally rectangular or other shape (e.g., cylindrical or other desired shape). As illustrated in  FIG.  7   , the extending arm  106  may be coupled to a bottom holder  105  via a ground bolt  120 . Ground bolt  120  extends a length of the housing  108 , to facilitate coupling of housing  108  to the second housing section  103 , via a top plate (discussed further herein).  FIG.  8    illustrates an additional top-down view of the low profile lighting adapter  100 . As illustrated in  FIG.  8   , live electrical connection  112  is disposed above bracket  150  along axis  140  and relative to the extended arm  106 . The live electrical connection  112  is configured to be actuated up and down (prior to or during installation) along axis  140 , in order to make electrical contact with different electrical circuits, as described herein. Because live electrical connection  112  actuates along axis  140  independently of live conductive bracket  150 , a lower profile lighting adapter  100  can be achieved. Ground screw  109  connects the top of the lighting adapter to ground bolt  120 , so as to hold the fully assembled lighting adapter together. 
       FIGS.  9  and  10    illustrate a bottom-up view of a low profile lighting adapter  100  with an extended arm  106  in accordance with the present disclosure. As illustrated, the extended arm  106  can include a depression  160  configured to receive an apparatus, such as a lighting fixture. Although the depression  160  is illustrated as having a generally circular shape with a hollow center, examples are not so limited and the depression  160  may have different shapes.  FIG.  9    illustrates a front view of the depression  160 , whereas  FIG.  10    illustrates a back view of the depression  160 . As described herein, the extended arm  106 , including the depression  160 , can rotate about an axis ( 140  illustrated in  FIGS.  1  through  8   ). The depression  160  can be configured to allow an attached apparatus to rotate about a second axis  141  (illustrated in  FIG.  9   ). 
       FIG.  11    illustrates an exploded view of the low profile lighting adapter  100  with an extended arm in accordance with the present disclosure. While the table in  FIG.  11    provides various example materials for the various components illustrated, examples of the present disclosure are not limited to the materials listed. Also, while  FIG.  11    illustrates a first live electrical connection  112 , preferred embodiments include a second live electrical connection disposed below live electrical connection  112 . The second live electrical connection (not illustrated) is stationary, and does not actuate as described herein. However, live electrical connection 12 extends along axis  140  via along bracket  150  in order to make electrical contact with a distal electrical circuit. 
     As further illustrated in  FIG.  11   , screws  101  hold the assembly together. Housing section  102  defines a channel therein for receipt of various electrical contacts, as well as a track for accommodating the combination of spring-like conductor bracket  150  and live lead contact  112 . Ground connection  110  completes a ground circuit path through other ground components ground bolt  120 , ground screw  109 , ground ring  118  (for connection to a lighting device or other accessory by a further conductor(not shown)) and washer  119 , shown in further detail in  FIGS.  21 A- 21 B , showing exploded and collapsed views, respectively, of the ground circuit path assembly. 
       FIG.  11    also shows components of the live circuit path for connecting a hot lead to a lighting device or other accessory that includes live connection lead  112  that is generally L-shaped, which is in sliding frictional engagement with undulating bracket  150  along one portion of the L, wherein the end of the live lead  112  slides along bracket  150 . Bracket  150  is received within a channel of housing portion  102  as illustrated in  FIGS.  13 C, and  22 A and  22 B , wherein  22 B is a cross section showing bracket beneath lead  112 . The drawings suggest an overlap between the two components, but they are intended to be separate, and relatively slidable. A distal end  153  of bracket  150  is in sliding contact with radially inner conductive wave ring  114  that in turn rests on top of conductive ring  116 . Wave ring  114  can be compressed to a predetermined extent in the assembly in order to achieve a desired contact force or stress in the ring  114  and/or to help control the amount of friction resisting rotation in the assembly to help in aiming the lighting device when it is installed in a track. Conductive ring  116  can then in turn be connected to a lighting device (or driver therefor) or other accessory by a further conductor (not shown). Various views of these components can also be seen in  FIGS.  19 A- 19 C , wherein  19 C is an exploded view, and the other views show clear relative placement of the components. 
       FIG.  11    also shows components of the neutral circuit path for connecting a neutral lead to a lighting device or other accessory. Neutral circuit path includes neutral lead  111  that is generally C shaped and has a lower, or distal, foot that is in sliding contact with outer wave ring  115  that is disposed radially outwardly with respect to ring  114 . Ring  115  rests atop conductive ring  117  that can be electrically coupled to a lighting device (or driver therefor) or other accessory by a further conductor (not shown). Various views of these components can also be seen in  FIGS.  20 A- 20 C , wherein  20 C is an exploded view, and the other views show clear relative placement of the components.  FIGS.  18 A- 18 C  show relative placements of the conductors forming the hot, neutral, and ground circuit paths with the remainder of the device removed for illustration purposes. 
       FIG.  11    also shows plate component  103  that is received by housing  108 . Housing  108  receives yoke or arm  106  therein, atop which rests the aforementioned electrical components. Plate  104  is also provided for maintaining relative conductor spacing, as well as inner bracket  105 . Lock clip  107  is also provided, described elsewhere herein. 
       FIGS.  12 A and  12 B  illustrate additional exploded views of the low profile lighting adapter  100  in accordance with the present disclosure. As illustrated in  FIG.  12 A , the housing  108  includes side walls to contain the plurality of rings, which enable the bottom holder or inner bracket  105  to rotate about the central axis of the low profile lighting adapter in 180 degrees. The extending arm  106  is coupled to the bottom holder  105 , thereby facilitating rotation of the extending arm  106  about the central axis of the low profile lighting adapter in 180 degrees. The plurality of rings are further protected by top plate  104 . The top plate  104  is configured to fit within housing  108  and couple to the second housing section  103  via the plurality of screws  101 . To enable a low-profile design, the second housing section  103  includes a central opening that is configured to receive the first housing section  102 . The first housing section  102  further includes a depression, or channel, configured to receive conductive bracket  150 , shown in cross section in  FIG.  22 B . 
       FIGS.  13 A and  13 B  illustrate different perspective views of the extending arm  106 . As discussed with regard to  FIGS.  6  and  7   , the extending arm includes a first portion  106 - 1  and a second portion  106 - 2 . The second portion  106 - 2  can have a generally circular shape, thereby enabling extending arm  106  to rotate within the housing of the low-profile lighting adapter. Additionally, the second portion  106 - 2  can include projections  156 , such as those illustrated on the side opposite of first portion  106 - 1 , to seat the extending arm  106  against the bottom holder  105  (as discussed with regard to  FIG.  15   ). While the first portion  106 - 1  is illustrated as having a generally rectangular shape, as illustrated in  FIGS.  9  and  10   , the first portion  106 - 1  can include a depression configured to receive an apparatus, such as a lighting fixture. It will be appreciated that the extending arm can have any desired length, and any desired cross sectional shape (e.g., rectangular, oval, circular, etc.). 
       FIGS.  14 A- 14 L  illustrate expanded views of various components of the low profile lighting adapter  100  described herein. For example,  FIG.  14 A  illustrates a top-down view of top plate  104 , whereas  FIG.  14 B  illustrates a bottom-up view of top plate  104 . The top plate  104  includes screw holes such that the top plate is coupled with the external housing (e.g.,  108  illustrated in  FIG.  1   ) and a second housing section (e.g.,  103  illustrated in  FIG.  1   ).

       FIGS.  15 A- 15 H  illustrate various expanded views of various components of the low profile lighting adapter  100  described herein.  FIG.  15 A  illustrates a top-down perspective view of the bottom holder (e.g.,  105  illustrated in  FIG.  7    and bracket  105  illustrated in  FIG.  11   ).  FIG.  15 B  illustrates another top-down perspective view of the bottom holder, and  FIG.  15 C  illustrates a bottom-up perspective view of the bottom holder. As illustrated, the bottom holder includes a series of concentric circular depressions configured to receive a plurality of rings (illustrated and described with regard to  FIG.  16   ) which enable rotation of the extending arm  106  as described herein. Moreover, the bottom holder includes a central hole  154  configured to receive a ground bolt  120 , so as to couple the bottom holder to a top portion of the low profile lighting adapter (e.g., via the second housing section  103  and top plate  104 ).

The lock clip illustrated in  FIGS.  15 G and  15 H  includes a plurality of tabs,  159 - 1  and  159 - 2 . Tabs  159 - 1  and  159 - 2  extend along a length of the lock clip. Tab  159 - 1  is configured to extend laterally beyond the width of the lock clip  107  to seat the lock clip within the housing illustrated in  FIGS.  15 D-F . Tab  159 - 2  is configured to extend along an outer edge of the housing, such that a user may apply a force to actuate the lock clip, such as along axis  140  illustrated in  FIG.  2   . 
       FIGS.  16 A- 16 F  illustrate various expanded views of further components of the low profile lighting adapter  100  described herein.  FIGS.  16 A and  16 B  illustrate top-down perspective views of a first housing section (e.g.,  102  illustrated in  FIG.  1   ), and  FIG.  16 C  illustrates a bottom-up perspective view of the first housing section. As described herein, the first housing can be inserted into a second housing section, illustrated in  FIGS.  16 D,  16 E, and  16 F . The first housing section includes a depression  161  configured to enable actuation of a live electrical connection, such as electrical connection  112  illustrated in  FIG.  4   . The movement of the live electrical connection is facilitated by a bracket which is disposed within depression  161 , such as bracket  150  illustrated and described with regard to  FIG.  12 A . The first housing section further includes a notch  162  which allows the live electrical connection to extend beyond the top surface of the first housing section. Opposite of the depression  161 , the first housing section includes a second notch  163 , configured to receive a ground connection, such as electrical ground connection  110  illustrated and described with regard to  FIG.  2   .  FIGS.  16 D and  16 F  illustrate top-down perspective views of the second housing section (e.g.,  103  illustrated and described with regard to  FIG.  2   ), whereas  FIG.  16 E  illustrates a bottom-up perspective view of the second housing section. As described herein, the second housing section is configured to couple with and receive the first housing section (e.g., illustrated in  FIGS.  16 A-C ), as well as the housing (e.g., illustrated in  FIGS.  15 D-F ). The second housing section includes depressions  164  and  165 , configured to receive a neutral electrical connection and a live electrical connection, respectively. While  FIG.  16 A  illustrates a notch  162  which enables a first live electrical connection to actuate up and down, depression  165  is configured to hold a second live electrical connection in a static position, such that one live electrical connection is configured actuate. 
       FIGS.  17 A- 17 G  illustrate various stages of disassembly of the low profile lighting adapter  100  in accordance with the present disclosure.  FIG.  17 A  illustrates the fully assembled low profile lighting adapter as described herein, without the second housing section (e.g.,  103  illustrated in  FIG.  1   ).  FIG.  17 B  illustrates the low profile lighting adapter with the housing  108  removed.  FIG.  17 C  illustrates the low profile lighting adapter with the top plate  104  removed.  FIG.  17 D  illustrates the low profile lighting adapter with the bottom holder  105  removed.  FIG.  17 E  illustrates the low profile lighting adapter with the extending arm  106  removed.  FIG.  17 F  illustrates the low profile lighting adapter with the lock clip  107  removed.  FIG.  17 G  illustrates the various electrical connections and ring assemblies of the low profile lighting adapter. As illustrated, the electrical ground connection  110 , is secured between the ground screw  109  and the ground bolt  120 . 
     It will be appreciated by those of skill in the art that the disclosed embodiments can be used in combination with lighting tracks of virtually any manufacture. Generally, these systems all connect a live, neutral and ground to a linear track. As one example, some luminaires have three metal tabs, and others have two tabs. Corresponding two circuit tracks will have four copper “channels” for live 1, live 2, neutral, ground and three channels for L1, L2, and neutral. 
     Some luminaire adapters require placing the adapter in the lighting track and then turning the entire adapter 90 degrees to make electrical contact with conductors in the lighting track. Other are inserted into the track and a knob located on the adapter is turned making the electrical contact (as compared to rotating the entire adapter). The rotatable electrically transmissive couplings described herein can also be applied to this type of lighting adapter. 
     The present disclosure has described one or more preferred embodiments. However, it should be appreciated that many equivalents, alternatives, variations, and modifications, aside from those expressly stated, are possible and within the scope of the invention.
