DETAILED DESCRIPTION

FIG. 1 shows an oblique upward facing view an exemplary light assembly 10 in accordance with the present disclosure. Light assembly 10 includes a light receptacle 12 receiving a light source, such as an LED, a connector 14 for insertion into a track of a track lighting system and a support section 16 connecting light receptacle 12 to connector 14. One end of support section 16 is fixed to light receptacle 12 and the other end of support section 16 is fixed to connector 14. Support section 16 encloses wiring for electrically connecting light receptacle to connector 14 such that connector 14 transmits electricity through support section 16 into light receptacle 12 to illuminate the light source housed within light receptacle 12. A rectangular cover 18 is provided at the interface between connector 14 and support section 16 that rests in the opening of the lighting track to obscure the connector 14 from view when connector 14 is inserted into a track. Light assembly 10 is centered on a vertically extending center axis CA that extends through light receptacle 12, support section 16 and connector 14. The terms axially, circumferential and radial, and derivatives thereof are used in reference to center axis CA, unless otherwise specified.

FIG. 2 shows an oblique downward facing view light assembly 10 showing further details of connector 14. Connector 14 has a three-dimensional shape such that a length of connector 14 is in a longitudinal direction D1 that is perpendicular to center axis CA, a width of connector 14 is in a lateral direction D2 that is also perpendicular to center axis CA and a height of connector 14 is in a direction D3 that is parallel to center axis. Connector 14 includes a casing 20, which is made of an electrically insulating material, for example plastic, a plurality of fasteners for removably fastening connector 14 to the track in the form of clips 22 extending outside of casing 20, and a plurality of electrical contacts 24a to 24f extending outside of casing 20 for electrically connecting connector 14 to electrical circuits of the track.

Casing 20 is defined by five outer exposed walls 26, 28, 30, 32, 34 (wall 34 is shown in FIG. 1) that are configured for being inserted into the track and define five sides 36, 38, 40, 42, 44 of casing 20. A sixth side of casing is joined with and covered by cover 18 and is obscured from view in FIG. 2. Casing 20 has a tapered shape in the longitudinal direction that allows connector 14 to be used with both a straight track and a curved track as discussed further below.

First side 36 defines an upper end face of casing 20, which is an upper end face of light assembly 10 for facing vertically into a track mounted on the ceiling. First side 36 is intersected by center axis CA and is opposite of the side of casing 20 that is covered by cover 18. In this example, cover 18 is snapped into casing 20 by four cover connectors in the form of prongs 19a—two on side 42 and two on side 44—that protrude vertically from a flat plate shaped base 19b of cover 18 between surfaces 31a, 34a of walls 32, 34 and surface 28c, 28d, 30c, 30d of walls 28, 30. First side 36 has outer dimensions that are defined by the length and width of connector 14. First side 36 is defined by an upper surface 26a of first wall 26, an upper surface 28a of a second wall 28 and an upper surface 30a of a third wall 30, with upper surface 26a defining a majority of first side 36.

Second and third sides 38, 40 define longitudinal ends of casing 20 and each have outer dimensions that are defined by the width and height of connector 14. Second and third sides 38, 40 are spaced equidistant from center axis CA. Second side 38 is defined by an end surface 28b of wall 28 and third side 38 is defined by an end surface 30b of wall 30.

Fourth and fifth sides 42, 44 define lateral sides of casing 20 and each have outer dimensions that are defined by the length and height of connector 14. Fourth side 42 is shown in FIG. 2 and fifth side 44 is shown in FIG. 1. Fourth and fifth sides 42, 44 are spaced equidistant from center axis CA. Fourth side 42 is defined by a lateral surface 28c of wall 28, a lateral surface 30c of wall 30, a lateral surface 26b of wall 26 and a surface 32a of wall 32. As shown in FIG. 1, fifth side 44 is defined by a lateral surface 28d of wall 28, a lateral surface 30d of wall 30, a lateral surface 26c of wall 26 and a surface 34a of wall 34.

Walls 28, 30 each include a respective recess 29, 31 formed in the respective surface 28b, 30b that define a respective edge 29a, 31a, which extends inward from the respective surface 28b, 30b in direction D1, for being gripped by a user's fingers to pull the connector 14 from the track. Surfaces 28b, 30b each have a U-shape such that edges 29a, 31a each have a U-shape. Walls 28, 30 also include slots 29b, 31b, respectively, for air passage into and out of an interior of the casing 20 for cooling the control unit inside of casing 20.

Clips 22 are provided on sides 42 and 44 of casing 20, with for example two clips 22 being provided on each of sides 42, 44. Each of clips 22 on side 42 extends through a respective slot 32b formed in wall 32 and a slot 26d formed in lateral surface 26b of wall 26 and, as shown in FIG. 1, each of clips 22 on side 44 extends through a respective slot 34b formed in wall 34 and a slot 26e formed in lateral surface 26c of wall 26. Clips 22 are flexible in direction D2 and pressed toward wall 26 when clips 22 are snapped into the track.

Electrical contacts 24a to 24f are also provided on sides 42 and 44 of casing 20, with three electrical contacts 24a to 24c being provided on each of side 42 and three electrical contacts 24d to 24f provided on side 44. Each of contacts 24a to 24c on side 42 extends through a respective slot 32c formed in wall 32 and each of contacts 24d to 24f on side 44 extends through a respective slot 34c formed in wall 34. Each of contacts 24a to 24f incudes a flat tab 25a within the plane of wall 32 and a protrusion 25b extending radially away from tab 25a and from wall 34 for contacting an electrical circuit in the track. Each of protrusions 25b includes two sections 25c that extend radially from opposite lateral edges of the respective tab 25a away from the respective tab 25a. The three contacts 24a to 24c on side 42 are all of different heights in direction D3 and the three contacts 24d to 24f on side 44 are all of different heights in direction D3 such that protrusions 25b on each side 42, 44 are each a different distance from a plane of surface 26a of first wall 26. In particular, of the three contacts 24a to 24c on side 42, referring to the view shown in FIG. 2, the contact 24a on the left is of the shortest height in direction D3, the contact 24c on the right is of the longest height in direction D3 and the contact 24b in the middle is of an intermediate height that is between the heights of the left contact 24a and the right contacts 24c. The three contacts 24d to 24f are configured in the same manner as contacts 24a to 24c and having varying heights such that each protrusion 25b on a respective one of sides 42, 44 has a unique vertical location. In other words, tabs 25a on each side 42, 44 are of different heights such that axial protrusions 25b on each side 42, 44 are different distances from the plane extending along the end face defined by side 36 and extending perpendicular to center axis CA. Accordingly, each axial protrusion 25b is configured to contact a different respective electrical contact of the track with each contact of the track having a unique height. A top end of each of tabs 25a on side 42 is provided at the bottom edge lateral side 26b of wall 26 and a top edge of wall 32 and a top end of each of tabs 25a on side 44 is provided at the bottom edge lateral side 26c of wall 26 and a top edge of wall 34.

As clearly illustrated in FIGS. 3 to 5, casing 20 of connector 14 has a maximum length Lc that is greater than a maximum width Wmxc of casing 20 and is greater than a maximum depth Hc of casing 20. In other examples, the maximum length Lc may be equal to the maximum width Wmxc. FIG. 3 shows a top plan view of light assembly 10 facing the end face of connector 14 and the end face of light assembly 10, FIG. 4 shows an elevation side view illustrating connector 14 viewed longitudinally and FIG. 5 shows an elevation side view illustrating connector 14 viewed laterally.

The maximum length Lc of casing 20 is defined on one end by surface 28b and on the other end by surface 30b. The maximum height Hc of casing 20 is defined on one end by upper surface 26a and on the other end by surfaces 20a that join an upper surface 18a of cover 18.

A lateral center plane CP_LT of casing 20 intersects and forms the lateral center of longitudinally extending sides 36, 42, 44 such that lateral center plane CP_LT divides casing 20 into two half sections 20′, 20″. A longitudinal center plane CP_LN of casing 20 intersects and forms the lateral center of laterally extending sides 38, 40 and longitudinally extending side 36. Both of lateral center plane CP_LT and longitudinal center plane CP_LN of casing 20 are coincident with center axis CA, and planes CP_LT and CP_LN intersect each other at center axis CA.

Casing 20 can further be defined as including three third section 21′, 21″, 21′″ each defining one-third (⅓) of the length of casing 20. Section 21″ defines a middle third of casing 20, while sections 21′, 21′″ define end thirds of casing 20. Sections 21′, 21′″ each include a longitudinal end of casing 20, with the longitudinal end of section 21′ being defined by side 40 and the longitudinal end of section 21′ being defined by side 38.

In order to allow connector 14 to be used with both a straight track and a curved track, middle section 21″ have a greater average width than each of end sections 21′, 21′″. In the example shown in the figures, sections 21′, 21′″ each have a decreasing width while extending away from middle section 21 to the respective longitudinal end of casing 20. Further, in the example shown in the figures, each of longitudinally extending sides 42, 44 extending laterally toward longitudinal center plane CP_LN while extending longitudinally away from lateral center plane CP_LT to join sides 38, 40. More specifically, the maximum width Wmxc of casing 20 is at a lateral center plane CP_LT of casing 20 and the minimum width Wmnc of casing 20 is at both of longitudinal end surfaces 28a, 30a with sides 42, 44 each being tapered while extending from lateral center plane CP_LT to longitudinal end surface 28a and while extending from lateral center plane CP_LT to longitudinal end surface 30a. Half section 20′ becomes thinner while extending away from lateral center plane CP_LT by surfaces of side 42 tapering while extending from lateral center plane CP_LT to an edge 46a defining a transition from side 42 to side 40 and surfaces of side 44 tapering while extending from lateral center plane CP_LT to an edge 48a defining a transition from side 44 to side 40. In the same manner, half section 20″ becomes thinner while extending away from lateral center plane CP_LT by surfaces of side 42 tapering while extending from lateral center plane CP_LT to an edge 46b, which defines a transition from side 42 to side 38, and by surfaces of side 44 tapering while extending from lateral center plane CP_LT to an edge 48b, which defines a transition from side 44 to side 38.

In other words, each of half sections 20′, 20″ of casing 20 has a decreasing width while extending longitudinally outward away from lateral center plane CP_LT. Each of sides 42, 44 of half section 20′ is tapered toward longitudinal center plane CP_LN of casing 20 while extending away from lateral center plane CP_LT all the way to side 40. In the same manner, each of sides 42, 44 of half section 20″ is tapered toward longitudinal center plane CP_LN of casing 20 while extending away from lateral center plane CP_LT all the way to side 40.

In the example shown, connector 14 is symmetrical with respect to lateral center plane CP_LT such that sections 20′, 20″ are identical except for the different heights of contacts 24a and 24c and the different heights of contacts 24d and 24f, and connector 14 is also symmetrical with respect to longitudinal center plane CP_LN.

Electrical contacts 24b, 24e are provided at the longitudinal middle of connector 14 and intersected by lateral center plane CP_LT, contacts 24c, 24f are adjacent to electrical contacts 24b, 24e, respectively, in half section 20′ and contacts 24a, 24d are adjacent to electrical contacts 24b, 24e, respectively, in half section 20″. In the example shown in the figures, all of electrical contacts 24a to 24f are provided in the longitudinal center third section 21″ of connector 14 such that contacts 24a to 24f are all arranged to contact the corresponding contacts of rails on both straight and curved tracks. Clips 22 are provided further away from lateral center plane CP_LT than contacts 24a to 24f such that contacts 24a to 24c are provided between clips 22 on side 42 and contacts 24d to 24f are provided between clips 22 on side 44.

Wall 26 is provided with two integrated plastic springs 27 to balance the tolerances to help avoid wobbling when moved in the track. Each of springs 27 is in one respective half 20′, 20″ such that springs 27 are equidistant from center axis lateral center plane CP_LT. Springs 27 are each centered on longitudinal center plane CP_LN.

FIG. 6 shows light assembly 10 with an exploded view of connector 14. As illustrated in FIG. 6, clips 22 are each fixed to an interior of casing 20 by screws 54 and wall 26 is fixed to the interior of casing 20 by screws 56. Electrical contacts 24a to 24f are fixed to a control unit in the form of a circuit board 50. Tabs 25a of contacts 24a to 24f are each fixed to a respective base 25c that is fixed in electrical contact with circuit board 50. Circuit board 50 is configured for switching connector 14 between two different electrical circuits. A first circuit includes electrical contacts 24a to 24c, and a second circuit is formed by electrical contacts 24d to 24f.

More specifically, circuit board 50 is configured to switch the transmission of electricity from a two-circuit rail to the light source of light assembly 10 between two different sets of electrical contacts of connector 14—i.e., the first set of electrical contacts 24a to 24c or the second set of electrical contracts 24d to 24f. An operator may switch the electrical input into connector 14 by actuating a mechanical switch 52 (FIGS. 2 and 3) on side 26 of casing 20. Circuit board 50 is configured so that, for each set of electrical contacts 24a to 24c and 24d to 24f, a first contact is connectable to a positive line, a second contact is connectable to a negative line and a third contact is connectable to a dimming control line. Thus, for example, contacts 24a and 24d may each be connectable to a respective distinct positive line, contacts 24b and 24e may each be connectable to a respective distinct negative line, and contacts 24c and 24f may each be connectable to a respective distinct dimming control line.

As illustrated in the example of FIG. 6, cover 18 is formed of two separate pieces 19c, 19d. Each of pieces 19c, 19d forms one half of cover 18 and includes part of base 19b and two of prongs 19a—one prong 19a for connecting to side 42 of casing 20 and one prong 19a for connecting to side 44 of casing 20. Each of pieces 19c, 19d includes a notch 19e. When pieces 19c, 19d are installed on connector 14, notches 19e together form a hole of cover 18 receiving and surrounding support section 16. Walls 32, 34 each includes two slots 35 extending therein in direction D3 (FIG. 2) that are recessed away from respective surfaces 32a, 34a in direction D2 for receiving a respective one of prongs 19a. To install cover 18 on casing 20, prongs 19a of piece 19c may first be pressed into slots 35 until prongs 18a snap into place on walls 32, 34 and piece 19c is removably fixed to casing 20, then prongs 19a of piece 19d may be pressed into slots 35 until prongs 19a snap into place on walls 32, 34 and piece 19d is removably fixed to casing 20.

FIG. 7 shows a cross-sectional side view of a track lighting system 60 in accordance with an example of the present disclosure. Tracking lighting system 60 includes the connecter 14 inserted inside of a track 62. Track 62 includes a frame 64, which may for example be formed of aluminum, insulating layers 66a, 66b held by frame 64 and a plurality of electrical contact lines 68a to 68f held by layers 66a, 66b. Lines 68a to 68c form a first electrical circuit and are held on one side of track 62 by insulating layer 66a and lines 68d to 68f form a second electrical circuit and are held on the other side of track 62 by insulating layer 66b. Each of lines 68a to 68c is at a different respective height and each of lines 68d to 68f is at a different respective height. Each set of lines 68a to 68c and 68d to 68f includes a positive line, a negative line and a dimming control line. Thus, for example, lines 68a and 68d may each be a respective distinct positive line, lines 68b and 68e may each be a respective distinct negative line, and lines 68c and 68f may each be a respective distinct dimming control line. In the example of FIG. 7, contacts 24a to 24c are in contact with lines 68a to 68c for transmitting electricity to power the light source of light assembly 10 when selected and contacts 24d to 24f are in contact with lines 68d to 68f for transmitting electricity to power and control the light source of light assembly 10. If two light assemblies 10 are inserted inside and thus connected to track 62 longitudinally offset from each other, one light assembly may be powered and controlled by lines 68a to 68c and the other light assembly may be powered and controlled by lines 68d to 68f.

Frame 64 includes flanges 64a configured for connecting to a support surface such as a ceiling and a base 64b formed by a horizontally extending wall defining a top surface of a 64c of a channel 70 defined by frame 64. One opposite sides of channel 70, frame 64 includes support rails 64d for holding clips 22 vertically in place inside of track 62. As connector 14 is pressed upward into track 62, clips 22 contact support rails 64d and are forced inward into respective slots 32b, 26d or slots 34b, 26e, until the noses of clip 22 are above the support rails 64d and thus snap into place to hold connector 14 inside of track 62. Frame 64 further includes two vertically extending side walls 64e, 64f extending downward from base 64b and laterally delimiting channel 70 therebetween. Each side wall 64e, 64f is provided with a support section 64g supporting a lower side of the respective insulating layer 66a, 66b. An upper side of each of insulating layers 66a, 66b is held by a lower side of the respective support rail 64d.

When connector 14 is inserted inside of track 62, cover 18 closes off the channel 70 in the region of connector 14, such that connector 14 is sandwiched vertically between cover 18 and base 64d. Side walls 64e, 64f have a greater height than connector 14 such that walls 64e, 64f extend vertically downward past lower surface 20a of casing 20 of connector 14.

FIG. 8 shows a cross-sectional side view of a track lighting system 80 in accordance with another example of the present disclosure. Tracking lighting system 80 includes two separate tracks 82, 84, with each of tracks 82, 84 being configured in the same manner as track 60, with the exception being that tracks 82, 84 share a base wall 86. Track lighting system 80, due to the dual tracks 82, 84, includes four separate and distinct circuits 88a, 88b, 88c, 88d that are configured for powering and controlling light assemblies separately and distinctly from each other. For example, connectors 14 of two different light assemblies 10 may be provided in track 82, with one of the light assemblies 10 being powered and controlled by circuit 88a and the other light assembly 10 being powered and controlled by 88a, and connectors 14 of two different light assemblies 10 may be provided in track 84, with one of the light assemblies 10 being powered and controlled by circuit 88c and the other light assembly 10 being powered and controlled by 88d. Tracking lighting system 80 may include a stem or aircraft cable integrated on the upper side to mount it to the ceiling in open gaps between connectors 14.

FIG. 9 shows light assembly 10 connected to a straight track 90, with connector 14 being inserted into track 90 and covered with cover 18. Track 90 has the same design as track 62 discussed with respect to FIG. 7.

FIG. 10 shows the light assembly 10 connected to a curved track 82, with connector 14 being inserted into track 92 and covered with an arc shaped cover 94. Track 82 has the same design as track 62 discussed with respect to FIG. 7, except that track 82 has a curved shape, with vertically extending side walls 64e, 64f in FIG. 7 being replaced by a vertically extending side wall 92a having a concave shape while extending longitudinally and a vertically extending side wall 92b having a convex shape while extending longitudinally, and with horizontally extending base wall 64b in FIG. 7 being replaced by horizontally extending base wall 92c having an arc shape while extending longitudinally. As noted above, the shaped of casing 20 allows connector 14 to be used with both the straight track 90 and the curved track 92. Arc shaped cover 94 is formed in the same manner as cover 18, with two separate pieces, each having four prongs 19a for snapping onto casing 20.

A method of using the lighting assembly 10 may include inserting the light assembly connector 14 into curved lighting track 92 and moving the light assembly connector 14 along curved lighting track and powering the light source of lighting assembly 10 via the curved lighting track 92. The method can then include inserting the light assembly connector 14 into straight lighting track 90 and moving the light assembly connector 14 along the straight lighting track 90 and powering the light source of the lighting assembly 10 via the straight lighting track 90.

Using connector 14 with a straight track 90 involves removably connecting cover 18 to connector 14 after connector 14 is preassembled with support section 16 and light receptacle 12, and using connector 14 with a curved track 92 involves removably connecting cover 94 to connector 14 after connector 14 is preassembled with support section 16 and light receptacle 12. The two piece design of covers 18, 94 allows such installation after preassembly of light receptacle 12, connector 14 and support section 16.

The preceding specification refers to specific exemplary embodiments and examples. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope as set forth in the claims that follow. The specification and drawings are accordingly to be regarded in an illustrative manner rather than a restrictive sense.
