DETAILED DESCRIPTION
[00103] Light fixtures can be secured to a substrate such as a ceiling or a wall. Such light fixtures can comprise a light source to generate the light. In some examples, the light fixture can also comprise a trim configured for securing the light source to the substrate. The trim can comprise both functional and decorative characteristics. In addition, some light fixtures can comprise adaptors disposed between the light source and the trim connecting the light source to the trim. The adaptors can help shape the light beam, provide various tilting functionalities, and the like. As such, in some examples one light fixture can comprise the light source, the adaptor, and the trim.
[00104] Given the decorative and functional elements of the trim and the adaptor, there may be many different possible combinations of light source, adaptor, and trim for a given line of light fixtures. To produce and stock an inventory of such a large number of possible products can be expensive and inefficient. The light source can be the most expensive component of the light fixture. In addition, the light source can be subject to a higher level of safety testing and certification compared to the adaptor and the trim. A modular light fixture wherein a few light sources can be used with any one of a plurality of adaptors and/or trims can reduce the cost and difficulty of providing a full set of light source, adaptor, and trim combinations, and can reduce the amount of cost and time spent for safety testing and certification.
[00105] In order to allow modular assembly of the light fixture from one or a few light sources connectable to one of a plurality of different adaptors and trims, the light source, adaptor, and trim can be reversibly securable to one another. In addition, in some example light fixtures the connection between the light source, adaptor, and trim components can also be measured and/or tested against engineering or safety specifications. For example, some example specifications may indicate that the connections are to be mechanically secure and also provide a water vapor barrier. In such examples, the reversible connections between the light source, adaptor, and the trim can act as water vapor- or air-tight barriers to comply with the specifications.
[00106] Fig. 1 shows a top perspective view of an example light source 100.
Light source 100 can be used as a component in a light fixture configured for modular assembly of the light source, the adaptor, and the trim. In some examples the light fixture can comprise light source 100, and need not comprise the adaptor or the trim. Light source 100 comprises a housing 102 terminating in a first end 104. Housing 102 comprises a housing connector 106 disposed proximate first end 104.
Housing connector 106 can be used for reversibly securing light source 100 to an adaptor and/or to a trim. Housing connector 106 can be disposed at, adjacent to, and/or abutting first end 104. In some examples, housing connector can be spaced from first end 104.
[00107] While Fig. 1 shows housing 102 as having a cylindrical shape, it is contemplated that in some examples a portion or all of the housing can have a shape other than cylindrical. Moreover, housing connector 106 can comprise spiral threading which can be disposed on an outer surface of the housing.
In other examples, the spiral threading can be disposed on an inner surface of housing 102. This spiral threading can be used to reversibly connect light source 100 to one of a plurality of trims and/or one of a plurality of adaptors which can in turn connect to trims.
[00108] While Fig. 1 shows housing connector 106 as comprising spiral threading, it is contemplated that in other examples the housing connector can comprise a different type of connector, including but not limited to, resiliently- or spring-biased members and the like. In addition, a light emitter can be disposed inside housing 102 to emit the light generated by light source 100.
[00109] Housing 102 can also comprise a second end opposite first end 104.
Moreover, light source 100 can also comprise a cover 110 to at least partially cover the second end of housing 102. Furthermore, light source 100 can comprise a connector 108 in electrical communication with the light emitter.
Connector 108 can be configured for electrically connecting the light emitter to a power source external to light source 100.
[00110] Fig. 2 shows another perspective view of light source 100. Fig. 2 shows a lens 112 received inside housing 102 proximate first end 104 and secured to housing 102. Lens 112 can be configured to modify the light propagating form the light emitter out of first end 104.
While Fig. 2 shows lens 112 received fully inside housing 102, it is contemplated that in other examples the lens can be partially received inside the housing.
[00111] Fig. 3 shows a side elevation view of light source 100. Fig. 3 shows housing 102, and housing connector 106 proximate the first end of housing 102. Housing connector 106 comprises spiral threading.
Fig. 3 also shows a further housing connector 114 disposed proximate the second end of housing 102.
Housing connector 114 can also comprise spiral threading disposed on the outer surface of housing 102.
While Fig. 3 shows housing 102 as have two housing connectors one proximate each end, it is contemplated that in some examples the housing need not comprise housing connector 114.
[00112] Fig. 4 shows a top plan view of light source 100. Fig. 5 in turn shows a bottom plan view of light source 100. Fig. 6 shows an exploded view of light source 100. Fig. 6 shows a heat sink 116 disposed inside housing 102. Screw holes 150 in housing 102 can be used to secure heat sink 116 to housing 102. Heat sink 116 can comprise a heat sink base 118 having a substantially circular shape. Heat sink base 118 can be receivable in the cylindrical housing 102. In examples where the housing can have a shape other than cylindrical, the heat sink and its based can have a shape to allow the heat sink to be received inside the housing.
[00113] Heat sink base 118 can comprise a first side 120 and a second side 126 opposite first side 120. Moreover, heat sink 116 can comprise an annular extension 122 extending out of a plane defined by heat sink base 118 and from first side 120 of heat sink base 118. In other examples the extension out of the plane of the heat sink base can have a shape other than annular, such as solid cylindrical, polygonal, and the like. Heat sink 116 can further comprise a plurality of blades 124 extending radially from annular extension 122. Blades 124 can be configured to facilitate heat exchange between heat sink 116 and an environment surrounding heat sink 116 by increasing a surface area of heat sink 116.
[00114] Fig. 6 also shows a light emitter 134 comprising a light emitting diode (LED) 136 disposed on a support. LED 136 is shown in dashed lines because the LEDs are disposed on the side of the support that is not visible in Fig. 6. It is contemplated that light emitter 134 can comprise one LED or any number of LEDs. The support can comprise an opening in a corner to allow for passage of electrical leads connecting to the LED. In addition, while Fig. 6 shows the light emitter comprising an LED, it is contemplated that in some examples light source 100 can comprise a light generator other than an LED, such as an incandescent, fluorescent, or halogen light generator.
[00115] Light emitter 134 can be disposed inside housing 102 and in thermal communication with heat sink 116. Light emitter 134 can be positioned to allow the light emitted by light emitter 134 to exit housing 102 through first end 104. For example, light emitter 134 can be disposed on second side 126 of heat sink 116. In some examples, light emitter 134 can be secured on second side 126 using thermal adhesive, and the like. In order to allow for the electrical leads of light emitter 134 to pass, heat sink 116 can comprise an opening 128 in heat sink base 118. The leads of light emitter 134 can also be considered as a portion or extension of connector 108. As shown in Fig. 6, opening 128 can extend at least partly through annular extension 122. In other examples, opening 128 can be positioned differently in heat sink base 118, and need not extend through annular extension 122.
[00116] Moreover, as shown in Fig. 6, light source 100 can also comprise cover 110 configured to at least partially cover second end 138 of housing 102. Cover 110 can comprise one or more cover openings 148 to facilitate heat exchange between an inside of housing 102 and an environment outside housing 102. The shape, size, number, and position of openings 148 can be chosen to provide sufficient heat =
exchange between inside and outside housing 102, while also providing some protection for the components inside housing 102 against external elements.
[00117] Cover 110 can also comprise screw holes 146, which can be aligned with screw holes 130 in heat sink 116. The screw holes in cover 110 and heat sink 116 can be used to secure cover 110 to heat sink 116. It is contemplated that in other examples the cover need not be secured to the heat sink, and can instead and/or in addition be secured to housing 102 or other components of light source 100. Cover 110 can also comprise a further cover opening 142 to allow for passage of connector 108 into housing 102.
[00118] Furthermore, Fig. 6 shows that housing 102 comprises a ridge 140 extending from an inner surface of housing 102, which housing has a cylindrical shape in Fig. 6. Ridge 140 can be oriented about axially along the cylindrical body of housing 102. Ridge 140 can be integrally formed with housing 102, or it can be separately form and then secured to housing 102. It is contemplated that in some examples the housing need not comprise a ridge.
[00119] Ridge 140 can be used to align heat sink 116 and cover 110 in relation to housing 102. Heat sink 116 can comprise notch 132 and cover 110 can comprise notch 144, the notches shaped to receive ridge 140 to allow for aligning heat sink 116 and/or cover 110 in the cylindrical portion of housing 102.
Housing 102 can comprise two ridges at diametrically opposite points of its inner surface, and heat sink 116 and cover 110 can also each comprise a pair of notches shaped, sized, and positioned to receive the ridges.
[00120] Fig. 7 shows an exploded view of a light source 200. Light source 200 can have a larger diameter than light source 100, and light source 200 can comprise similar components with similar functions and arrangement as in light source 100. Light source 200 can comprise a housing 202 having a first end 204 and a second end 238 opposite the first end. Housing 202 can comprise a housing connector 206 disposed on housing 202 proximate first end 204. Housing connector 206 can comprise a spiral threading on an outer surface of housing 202. Housing 202 can also comprise a ridge 240 and a screw hole 250.
[00121] Light source 200 can also comprise a lens 212 shaped and size to be secured to housing 202 proximate first end 204. Lens 212 can comprise resiliently biased snap fasteners 214 for securing lens 212 to housing 202. In other examples, the lens can be secured to the housing using fasteners or securing elements other than snap fasteners.

. .
[00122] Moreover, light source 200 can comprise a heat sink 216 comprising a heat sink base 218, an annular extension extending from a side of heat sink base 218, and a plurality of blades extending radially from the annular extension. Heat sink 216 can comprise two openings 228 (only one is visible in the view shown in Fig. 7) which can allow electrical leads of light emitter 234 to pass through heat sink base 218 and connect with connector 208. The leads can comprise two separate wires, with each wire passing through a corresponding one of the two openings 228. Heat sink base 218 can also comprise notch 232 to receive ridge 240. Moreover, heat sink 216 can comprise screw holes 230, to allow for connecting a cover 210 to heat sink 216.
[00123] Light emitter 234 can, in turn, comprise one or more LEDs 236, disposed on a support. LEDs 236 are shown in dashed lines because they are disposed on the side of the support that is not visible in Fig. 7. Light emitter 234 can be disposed on, and in thermal communication with, the side of heat sink base 218 opposite the annular extension. Furthermore, light source 200 can comprise a cover 210 having a plurality of openings 248, a further opening 242 for allowing the passage of connector 208, screw holes 246 for connecting to heat sink 216, and notches 244 for receiving ridges 240 of housing 202.
[00124] Turning now to Fig. 8, a top perspective view of an example adaptor 300 is shown. Adaptor 300 can be reversibly securable to light sources, including but not limited to light sources 100 or 200.
Adaptor 300 can comprise a first connector 302 and a second connector 304 coupled to first connector 302. Adaptor 300 can also comprise a light conduit 306 extending from first connector 302 to second connector 304 and coupling the two connectors.
[00125] As shown in Fig. 8, adaptor 300 can generally have a frustoconical shape. In some examples, light conduit 306 can have a frustoconical inner shape, terminating in a small open end 308 and a large open end 310. First connector 302 can comprise a spiral threading proximate small open end 308 and disposed on the inner surface of the adaptor. This spiral threading can be configured for reversibly mating with the housing spiral threading for reversibly securing the adaptor to the housing, such as housing 102 of light source 100. Similarly, second connector 304 can comprise a spiral threading proximate large open end 310 and disposed on the outer surface of the adaptor. This spiral threading can be configured for reversibly mating the adaptor to a trim.
[00126] While Fig. 8 shows the spiral threading at the first connector 302 and second connector 304 on the inner and outer surfaces of adaptor 300 respectively, it is contemplated that in other examples, both spiral tiffeadings can be on the same inner or outer surface of adaptor 300, or the spiral threading proximate small open end 308 can be on the outer surface while the spiral threading proximate the large open end 310 can be on the inner surface of adaptor 300. Moreover, it is contemplated that in other example adaptors, first and second connectors can comprise connection mechanisms other than spiral threading. The structure and positioning of the connectors can be selected to be mateable with the housing connector of the light source and the connector for the trim.
[00127] Moreover, it is contemplated that the light conduit can comprise a passage for allowing light emitted by the light source to pass through the adaptor towards the trim.
Furthermore, the light conduit can be continuous (e.g. as shown in Fig. 8) or in some examples it can have openings in addition to the small and large open ends. In some examples, the light conduit can have a shape other than frustoconical.
In addition, in some examples the light conduit can comprise a light guide such as a light rod or an optical fiber.
[00128] Furthermore, in some examples the inner shape of the light conduit can be used to control or shape the profile of the light beam that emerges from the adaptor. For example, a converging light conduit in an adaptor (e.g. where the light receiving open end of the conduit is larger than the light emitting open end) can tighten or reduce a light beam's cross-section or diameter.
Conversely, a diverging light conduit (e.g. where the light receiving open end is smaller than the light emitting open end, as for example in the frustoconical shape of adaptor 300) can allow the light emitted by the light source to diverge and spread out further as it passes through the light conduit of the adaptor. In some examples, the adaptor can comprise materials including, but not limited to metals, polymers, composites, and the like.
[00129] Fig. 9 shows light source 100 and adaptor 300 separate from one another. Fig. 10, in turn, shows light source 100 and adaptor 300 connected to one another. The light source and the adaptor can be reversibly connected or coupled to one another by connecting housing connector 106 (shown in Fig.
9) of light source 100 to first connector 302 of adaptor 300. When the housing and first connectors comprise spiral threading, connecting the light source to the adaptor can comprise mating the two spiral threadings together, or in other words, by screwing the light source and the adaptor together. The use of spiral threading in the housing and first connectors can allow for a mechanically strong coupling that can be reversible. In addition, it can allow for either the light source or the adaptor to be reversibly couplable with other components, including other light sources, adaptors, and trims, that have complementary spirally threaded connectors. In some examples, connection using spiral threading can also provide a connection that is substantially air-, gas-, and/or water vapor-impermeable.
Such impermeability can address at least some of the requirements for the engineering, safety, and/or certification specifications against which the light fixture can be tested.

. .
[00130] Fig. 11 shows a top perspective view of an example trim 400 for securing a light fixture to a substrate. In some examples, the trim can be partially or entirely decorative.
Trim 400 can comprise a trim base 402 configured to interface with the substrate. Trim base 402 can comprise a trim opening 404 configured to allow passage of the light emitted by the light emitter of a light source such as light source 100. Moreover, trim 400 can comprise a trim connector 406 coupled to trim base 402. Trim connector 406 can be configured to reversibly couple trim 400 to one or more of a light source such as light source 100 and an adaptor such as adaptor 300.
[00131] As shown in Fig. 11, trim connector 406 can comprise a trim spiral threading proximate trim opening 404. In other examples, the trim connector can comprise a fastening or connecting mechanism other than spiral threading, and the trim connector can be located at a position on trim 400 different than being proximate to the trim opening. The spiral threading of trim connector 406 can be shaped and sized to reversibly mate and connect with the housing connector of a light source such as light source 100 or the second connector of an adaptor such as adaptor 300.
[00132] Moreover, trim 400 can comprise trim connector clips 408 coupled to trim base 402. Clips 408 can be biased in the position shown in Fig. 11 by springs. When installing trim 400 in a substrate, a hole is made in the substrate. Clips 408 are bent inwards towards one another and against the resilient force of the springs. Then trim 400 is installed in the hole and clips 408 are allowed to return towards the position shown in Fig. 11 under the resilient force of the springs. This movement and force of the clips pinches the edges of the substrate between trim base 402 and the resiliently-biased clips 408, thereby securing trim 400 to the substrate.
[00133] While Fig. 11 shows trim base 402 as having a circular outer perimeter, it is contemplated that in other examples the trim and its base can have a different shape such as square, square with rounded comers, rectangle, oval, and the like. In addition, a portion of the trim can rest outside of the substrate and be a visible portion of the light fixture when installed in the substrate.
This portion can also have different shapes and profiles. Fig. 12 shows a bottom perspective view of trim 400, depicting the shape of the portion of trim base 402 that would be visible when trim 400 is installed in the substrate.
[00134] Turning now to Fig. 13, light source 100, adaptor 300, and trim 400 are shown. Light source 100 can reversibly connected to adaptor 300 by screwing housing connector 106 with first connector 302. In turn, second connector 304 and trim connector 406 can also both comprise spiral threading. This can allow adaptor 300 to be connected to trim 400 by screwing second connector 304 with trim connector 406. These connections can allow for assembling a light fixture as shown in Fig. 14, which fixture can comprise the light source, the adaptor, and the trim. It is also contemplated that in other examples (not shown), the light fixture can comprise the light source connected directly to the trim.
[00135] Fig. 15 shows a bottom perspective view of trim 400 and adaptor 300 connected together.
Fig. 16 shows a bottom plan view of the trim and adaptor shown in Fig. 15.
Fig. 17 shows a top plan view of the trim and adaptor shown in Fig. 15. Moreover, Fig. 18 shows a bottom perspective view of the light fixture shown in Fig. 14. Fig. 19 shows a bottom plan view of the light fixture shown in Fig.
14. Fig. 20 shows a top plan view of the light fixture shown in Fig. 14.
[00136] Fig. 21 shows another example adaptor 500, which can comprise a first connector 502, a second connector 504 connected to first connector 502, and a light conduit extending from first connector 502 to second connector 504. Light conduit 506 can comprise a frustoconical inner shape having a small open end 508 and a large open end 510. First connector 502 can comprise spiral threading disposed on an inner surface of the light conduit 506 proximate small open end 508. Second connector 504 can comprise spiral threading disposed on an outer surface of the light conduit 506 proximate large open end 510. While the outer surface of light conduit 506 is shown as having two portions at different slopes and/or orientations, the inner surface of light conduit 506 can define a frustoconical shape with a single slope along the axial length of the conduit.
[00137] Fig. 22 shows an exploded view of adaptors 500 and a trim 600. Trim 600 comprises a trim base 602 having two trim openings 604. A trim connector 606 can be secured proximate each trim opening 604 using blocks 612 and respective screws 614 receivable into blocks 612. In other examples (not shown in Fig. 22), the trim connector can be integrally formed with the trim base, or can be secured to the trim base using a securing mechanism other than blocks and screws. Trim connector 606 can comprise a ring 610 having spiral threading on its inner surface for reversibly mating with the spiral threading on second connector 504 of adaptor 500. Trim connector 606 can also directly connect to housing connector of light sources. Moreover, trim 600 can comprise clips 608 for securing trim 600 to the substrate in which trim 600 is installed.
[00138] Fig. 23 shows a top perspective view of trim 600 connected to adaptors 500. Fig. 24 shows a right side elevation view of trim 600 connected to adaptors 500. Fig. 25 shows a cross-sectional view of trim 600 connected to adaptors 500. Fig. 25 shows the spiral threading at first connector 502 of adaptors 500. Fig. 25 also shows spiral threading of second connector 504 cooperating and mating with the spiral threading of trim connector 606. Fig. 25 also shows that light conduit 506 can comprise an outer surface that has at least two sections with two different slopes, while the inner surface of light conduit 506 can define a frustoconical shape having a constant slope. Furthermore, Fig. 26 shows a front side elevation view of trim 600 connected to adaptors 500. Fig. 27, in turn, shows a top plan view of trim 600 connected to adaptors 500.
[001391 Turning now to Fig. 28, a top perspective view is shown of an example adaptor 700 connected to an example trim 800. Trim 800 can comprise a trim base 802 and clips 808.
Adaptor 700, in turn, can comprise a first connector 702. Fig. 29 shows as exploded view of trim 800 and adaptor 700. Trim 800 comprises a trim opening 804 in trim base 802, and a trim connector 806 disposed proximate trim opening 804. In Fig. 29, trim connector 806 is shown as comprising a spiral threading. In other examples (not shown in Fig. 29), the trim connector can comprise a mechanism for reversibly securing the trim to adaptors and/or light sources, which mechanism can be different than a spiral threading.
[00140] In adaptor 700, first connector 702 (shown in Fig. 28) can be moveably coupled to a second connector 704, such that second connector 704 is able to reversibly tilt along three different axes relative to first connector 702. Such multi-axis tilting can be achieved using a gimbal mechanism. The gimbal can comprise a hollow spherical segment 706 received inside a receiving component formed from first ring 708, spacer ring 710, and second ring 712. These three rings together can define an inner space for receiving spherical segment 706.
[00141] The inner space can have a first open end 714 having a first diameter and a second open end 716 opposite first open end 714, second open end 716 having a second diameter.
The inner space can further have an inner diameter measured at a point between first open end 714 and second open end 716.
The first diameter and the second diameter can be smaller than the outer equatorial diameter of spherical segment 706, and the inner diameter can be larger than the outer equatorial diameter. In this arrangement hollow spherical segment 706 can be captured in the inner space while remaining moveable relative to the receiving component.
[00142] The gimbal structure of adaptor 700 can be assembled by placing spherical segment 706 into ring 712. Spherical segment 706 does not pass through ring 712 because the outer equatorial diameter of spherical segment 706 is larger than the diameter at second open end 716.
Next, spacer ring 710 can be placed on ring 712 and around spherical segment 706. Subsequently, ring 708 can be placed on spacer ring 710 and also around spherical segment 706. Then, first ring 708, spacer ring 710, and second ring 712 can be secured to one another, using for example fasteners such as screws that extend through all three rings. As the diameter at open end 714 is smaller than the outer equatorial diameter of spherical segment 706, spherical segment 706 cannot pass through open end 714 either, and is as such captured in the inner space defined by rings 708, 710, and 712 and between first open end 714 and second open end 716. While captured, spherical segment 706 can tilt relative to the rings 708, 710, and 712 along three different axes. This type of movement can be analogous to a gimbal or a universal joint movement.
Moreover, while Fig. 29 shows one example structure of achieving gimbal movement between the first connector (which is part of spherical segment 706) and second connector 704 (which is part of second ring 712), it is contemplated that in other examples different structures can be used, including but not limited to, ball and socket joints, universal joints, and the like.
[00143] In other examples of the gimbal structure, the inner component need not be a spherical segment, and can be substantially spherical or have a different curvature profile. Moreover, the receiving component need not be formed of three rings, and can have a structure different than that shown in Fig.
29. For example, the receiving component can comprise one piece and can be formed around the inner component to capture the inner component.
[00144] Hollow spherical segment 706 can define a light conduit for passage of the light generated by a light source such as light source 100 or 200. Moreover, first connector 702 (shown in Fig. 28) and second connector 704 can comprise spiral threading. First connector 702 can be configured to reversibly mate with the housing connector of a light source such as light source 100 or 200. Second connector 704 can be configured to reversibly mate with a trim connector such as trim connector 806 of trim 800.
[00145] Fig. 30 shows a front side elevation view of the of adaptor 700 connected to trim 800. Fig.
31 shows a cross-sectional side elevation view of adaptor 700 connected to trim 800. Fig. 31 shows a light conduit 718 formed inside spherical segment 706. Fig. 31 also shows spiral threading of first connector 702, and also spiral threading of second connector 704 mated with the spiral threading of trim connector 806. Fig. 32 shows a right side elevation view of adaptor 700 connected to trim 800. Fig. 33 shows a top plan view of adaptor 700 connected to trim 800.
[00146] While Figs. 28-33 are described as showing a gimbal adaptor and a trim, in some examples the gimbal structure or functionality can be incorporated into the trim whereby the trim connector can tilt about three different axes, or gimbal, relative to the trim base. In such examples, the first connector of the gimbal (see for example first connector 702 shown in Fig. 28) can act as the trim connector for such a gimbal trim. Moreover, in such an example, the trim connector can be moveable or tiltable about three different axes relative to the trim base.
[00147] Fig. 34 shows an exploded view of light source 100 and an example adaptor 900. Adaptor 900 comprises a first connector 902, a second connector 904, and a light conduit 906 extending from first connector 902 to second connector 904. Instead of spiral threading, adaptor 900 comprises a pair of resilient tines 908 secured to light conduit 906 and disposed inside light conduit 906 proximate a first open end 910 of adaptor 900.
[00148] To connect a light source such as light source 100 to adaptor 900 via first connector 902, the housing connector can be received into light conduit 906 through first open end 910. The housing of the light source can deform the two tines 908 away from one another and also away from a central axis of light conduit 906, against the resilient force of tines 908. This resilient force can, in turn, secure the light source to adaptor 900.
[00149] Adaptor 900 can also comprise a second open end 912 opposite first open end 910. Walls of light conduit 906 can be turned back or doubled back at second open end 912 to form a lip 914 proximate second open end 912. Lip 914 can form part of second connector 904.
[00150] Fig. 35 shows light source 100 received in and connected to adaptor 900. Tines 908 can be seen as having been deformed away from one another by the housing of light source 100. Fig. 36 shows a bottom perspective view of light source 100 connected to adaptor 900. Fig.
37 shows a side elevation view of light source 100 connected to adaptor 900. Fig. 38 shows a top plan view of light source 100 connected to adaptor 900. Moreover, Fig. 39 shows a bottom plan view of light source 100 connected to adaptor 900.
[00151] Fig. 40 shows an example trim 1000, comprising trim base 1002, a trim opening 1004 in trim base 1002, and trim connector clips 1006 which can act as the trim connectors.
These trim connector clips 1006 can be configured to be resiliently deformed by a received component which can comprise a light source or an adaptor such as adaptor 900, when the received component is coupled to trim 1000 such that a resilient force of trim connector clips 1006 pushes against the received component to secure the received component to trim 1000. For example, lip 914 of second connector 904 (shown in Fig. 34) can be received in trim 1000 and deform connector clips 1006.
1001521 Moreover, while Fig. 40 shows trim 1000 as having three connector clips evenly spaced around trim opening 1004, it is contemplated that in other examples the trim may have a different number of connector clips that may be positioned differently. Moreover, in other examples the design of the clips can be different that those of connector clips 1006.
[00153] Fig. 41 shows a bottom perspective view of trim 1000. Fig. 42 shows a bottom plan view of trim 1000. Fig. 43 shows a top plan view of trim 1000. Fig. 44, in turn, shows light source 100 connected to adaptor 900, and adaptor 900 being inserted into trim 1000. Fig. 45 shows light source 100 connected , to adaptor 900, and adaptor 900 inserted into and connected to trim 1000. Fig.
46 shows a bottom perspective view of light source 100, adaptor 900, and trim 1000 connected together. Fig. 47 shows a side elevation view of light source 100, adaptor 900, and trim 1000 connected together. Fig. 48 shows a top plan view of light source 100, adaptor 900, and trim 1000 connected together. Fig. 49 shows a bottom plan view of light source 100, adaptor 900, and trim 1000 connected together.
[00154] Fig. 50 shows an example trim 1100, comprising a trim base 1102, a trim opening 1104 in trim base 1102, and trim connector clips 1106. Clips 1106 are, in turn, secured to a support portion 1112.
Support portion 1112 itself is pivotably connected via connecting members 1116 to a portion 1114 of trim base 1102. Support portion 1112 can pivot about two diametrically opposite pivot points 1110 (only one is visible in Fig. 50) relative to portion 1114 of trim base 1102. As such, trim connector clips 1106 can form a part of the trim connector that can be movably and/or pivotably coupled to trim base 1102.
[00155] In some examples, not shown, support portion 1112 can be reversibly connectable to portion 1114 or other portion of trim base 1102. Such a detachable support portion, that can reversibly connect to both a light source/adaptor and a trim, can also be described itself as another example adaptor. The first connector of such an adaptor can comprise clips 1106, and the second connector can comprise components such as connecting members 1116 that can reversibly connect to portion 1114 or other portions of trim base 1102. Moreover, in such an adaptor the first connector can be described as being pivotably connected to the second connector, with the second connector being able to reversibly tilt along an axis relative to the first connector.
[00156] Fig. 51 shows a bottom perspective view of trim 1100. Fig. 52 shows trim 1100 connected to adaptor 900, which is in turn connected to light source 100. In Fig. 52 trim 1100 is shown in the untilted position. Fig. 53, in turn, shows trim 1100 in a tilted position, connected to adaptor 900 which is in turn connected to light source 100. As such, Figs. 52 and 53 depict a light fixture, capable of being modularly assembled from light sources, adaptors, and trims, which light fixture can reversibly tilt about one axis.
[00157] Fig. 54 shows an example trim 1200, which is a double trim. Each of the two trims has a structure similar to trim 1000. Fig. 55 shows a bottom perspective view of trim 1200. Fig. 56 shows an example trim 1300, which is a quadruple trim arranged in a square. Each of the four trims has a structure similar to trim 1000. Fig. 57 shows a bottom perspective view of trim 1300.
Multiple trims, in linear, square, or other arrangements are contemplated for trim 1000, and for the other trims disclosed herein.
[00158] The example light sources, adaptors, and trims described herein can be combined in many different combinations. Since light sources tend to be relatively expensive to produce, a few different types of light sources such as light sources 100 or 200 can be produced. These light sources can then reversibly connect to one of a large variety of trims or to adaptors which can in turn connect to trims.
Adaptors and trims are relatively less expensive to produce, and may be subject to less or no testing or certification. As such, large varieties of adaptors and trims can be relatively quickly and inexpensively produced. Since light fixtures can be modularly assembled from the light sources, trims, and adaptors, the large variety of trims and adaptors can provide a large selection of light fixtures, which can be produced and stocked more quickly and less expensively than if an equal number and variety of light fixtures had to be produced in one piece and including a dedicated light fixture.
[00159] The spiral threading coupling between the light source, adaptor, and trim can provide for a quick, reversible, and yet mechanically strong coupling. Moreover, in cases where the connections between the light source, adaptor, and trim are to be tested and certified for being air-tight or moisture/vapor impermeable to predetermined thresholds, the spiral threading couplings can be designed to meet these thresholds.
[00160] In addition, the light fixtures described herein can be packaged as kits comprising a light source and one or more of: one or more trims and one or more adaptors. These light sources, adaptors, and trims can be similar to those described herein.
[00161] The light fixtures described herein can be installed by first obtaining a light source similar to a light source described herein, including but not limited to light sources 100 and 200. Next, the light source can be coupled to a trim to form the light fixture, and the coupling can be reversible. In some examples, coupling the light source to the trim can be indirect, comprising coupling the light source to an adaptor and coupling the adaptor to the trim. In other examples, the light source can be directly coupled to the trim.
[00162] Next, the light fixture can be inserted into an opening in the substrate in which the fixture is to be installed. After the inserting, the light fixture can be secured to the substrate, for example using resiliently- or spring-biased clips of the trim. In some examples, the light source need not be inserted into an opening in the substrate, and can be secured to a surface of the substrate.
[00163] The above-described are examples and alterations and modifications may be effected thereto, by those of skill in the art, without departing from the scope of the invention which is defined solely by the claims appended hereto.
