Detailed Description

10044] Referring to the drawings, there is illustrated by way of example some embodiments of a lighting system 100 that are in accordance with the present disclosure. Where like reference numerals are used in the following description, the features are considered to be the same unless specified as being otherwise.

10045] Figures 1 to 13 illustrate a first embodiment of an electrical fitting, with the electrical fitting being in the form of a lighting system 100. It would be understood by one skilled in the art that the disclosed adapter 10 and attachment 30 may also be integrated with other electrical fittings such as power boards, fans, heaters, air conditioners etc. It would also be understood by one skilled in the art the shape and dimensions of the disclosed adapter and attachments may differ from one electrical fitting to another.

10046] The illustrated lighting system 100 comprises a light fitting 50 in the form of a LED light batten. The LED batten has an elongate hollow body 52 that extends between opposing first 53 and second 54 distal ends. Each of the first 53 and second 54 distal ends define an opening 56 into the hollow of the light fitting 50 (e.g. Fig. 4). It would be understood that the cross-sectional size and shape of the body 52 can vary between embodiments of the light fitting 50. Similarly, the size, shape and location of the opening 56 can be varied between embodiments of the light fitting 50. For example, in some embodiments not shown, an opening 56 can be formed intermediate the first 53 and second 54 distal ends of the light fitting 50.

10047] Referring now to Figures 5 and 6, an adapter 10 is illustrated, the adapter acting as the interface that releasably couples between the light fitting 50 and one or more interchangeable attachments 30. A rear facing side 12 of the adapter 10 defines a generally planar surface that extends laterally, in use, relative to the opening 56 of the light fitting 50. The adapter 10 may have at least one flange 14,15,17 arranged to project from the rear facing side 12 so as to locate at least partially within the lightfitting 50. The example adapter 10 has a plurality of flanges 14,15,17 arranged to extend longitudinally away from the rear facing side 12 of the adapter 10. The flanges 14,15,17 are located adjacent to, but inset from, the outer perimeter of the adapter 10 cross-section, defining a non-continuous border around the rear facing side 12 of the adapter 10. Some of the flanges 14,15,17 are formed as substantially flat tabs 14 that can assist with correctly locating the adapter 10 relative to the opening 56 of the light fitting 50. At least one flange 15 on each of the sides of the adapter 10 is formed as a semi-flexible protrusion 15, having a ramped protuberance 18 that juts outwardly therefrom. At least two flanges 17 along the in-use bottom side of the adapter 10 are formed to define semi- flexible hooks 17, the outer edge of the hooks 17 defining a ramp surface. In a variation, not shown, flanges 14,15,17 could instead be arranged as a singular flange that, for example, defines a border around at least a portion of the perimeter of the rear facing side 12 of the adapter 10.

10048] In use, the rear facing side 12 of the adapter 10 is operable as a socket that faces, and located, internally within the light fitting 50 whereby the adapter 10 can be retained relative to the opening 56 of the light fitting 50. As the rear facing side 12 of the adapter is slidably inserted through the opening 56, the flanges 14,15,17 locate within the hollow light fitting 50 adjacent the walls of the body 52. The protrusions 15 and hooks 17 are flexibly deflected as their respective ramped surfaces are engaged by the interior wall of the body 52 of the light fitting 50. The deflection is maintained until the protrusions 15 and hooks 17 snap-engage into a corresponding slot 58 that is formed in the walls of the body 52. The reverse edge of each of the protrusions 15 and hooks 17 (i.e. on the opposing side from the ramped portion) catches against the side of a respective slot 58, thereby securing the adapter 10 to the light fitting 50.

10049] The coupling between the adapter 10 and the light fitting 50 can be undone to detach the adapter from the opening 56 by depressing the protrusions 15 and hooks 17 into a position in which they are not engaged with a respective slot 58. The flanges 14,15,17 can then be slidably removed from within the body 52 of the light fitting 50.

10050] In some embodiments, the flanges 14,15,17 can be arranged to be press-fit into the light fitting 50 to facilitate a releasable coupling therebetween that is sufficient to retain the adapter 10 within the opening 56.

10051] The outward facing side 22 of the adapter 10 faces externally away from the light fitting 50 and defines a substantially planar surface that extends laterally, in use, relative to the opening 56. A plurality of parallel ridges 24 are embossed to project longitudinally away from the outward facing side 22 of the adapter 10. The ridges 24 are arranged to extend upwards from a base of the adapter 10 for at least part of the height of the adapter 10. The ridges 24 form guide rails that, in use, facilitate smooth interfacing and sliding engagement between the adapter 10 and the attachment 30.

10052] The arrangement of the ridges is symmetrical laterally across the outward facing side 22 of the adapter 10. Each of the laterally outermost ridges 24 comprises an overhanging flange 25 that projects laterally outwards away from the respective upper edge of each ridge, with the overhanging flange 25 extending along a portion of the length of each ridge 24. Each of the overhanging flanges 25 projects in an opposing relative direction laterally across the adapter 10, and away from a respective one of the ridges. For example, each of the overhanging flanges 25 can define an L-shaped protrusion with the laterally outermost ridges 24.

100531 Referring now to Figures 7 to 12, the configuration of the set of ridges 24 on the outward facing side 22 of the adapter 10 is arranged to correspond to an opposing set of channels 34 that are formed on each of the interchangeable attachments 30. An odd (e.g. Fig 15) or even (e.g. Fig 6) number of ridges 24 can be formed on the outward facing side 22 of the adapter 10, with a corresponding number of channels 34 being formed on each of the attachments 30, so as to form together a coupling arrangement for mounting the attachment 30 to the adapter 10. The overhanging flanges 25 of the pair of outermost ridges 24 of the adapter 10 also correspond to a pair of indented grooves 35 that are formed on each side of the interface of each interchangeable attachment 30. For example, the indented grooves 35 can define an L-shaped groove with each of the channels 34. In addition, the rim 16 of the adapter 10 comprises an indent 27 along the respective opposing sides of the adapter 10. These indents 27 can be mated with a correspondingly shaped rail 37 that are adapted along each of the inwardly facing side walls of the attachment 30.

10054] In use, the adapter 10 and attachment 30 can be releasably coupled together by sliding the corresponding ridges 24 and channels 34 along one another. When the attachment 30 is mounted to the adapter 10, the engagement between the ridges 24 and channels 34 restricts the coupling from movement laterally across the lighting system 100. The engagement between the indents 27 and rails 37 restricts the coupling from movement longitudinally along the lighting system 100.

10055] The attachment 30 can take the form of a number of embodiments, with each variation comprising an identical coupling arrangement so as to facilitate a compatible coupling with the adapter 10. The attachments 30 are thus designed to be modular and interchangeable. Referring to Figures 7 to 10, the attachment 30 generally comprises a cover portion 32 and an internal portion 31. The internal portion 31 can be integrated with, or coupled to, the cover portion 32. Together, the internal portion 31 and cover portion 32 comprise the channels 34 and indents 37 that facilitate the mounting of the attachment 30 to the adapter 10. By covering the internal portion 31, the interior hollow of the attachment 30 can be protected from the ingress of contaminants, such as dirt.

100561 Referring to Figures 14A to 14E, in some forms (e.g. Fig 14A), the attachment 30""can be a cover that, when coupled to the adapter 10, substantially conforms to the adapter 10 so as to provide a low profile whilst protecting the adapter 10 and reducing the ingress of dirt or other contaminants therethrough into the light fitting 50. In some forms, the attachment 30 can be a functional module. As would be appreciated by one skilled in the art, the function performed or facilitated by the attachment 30 can be varied by configuring the hardware and/or software that are stored within the module.

10057] For example, in some forms, the attachment 30 can comprise a motion sensor such as a PIR or microwave sensor module. In some forms, the attachment 30 can comprise additional features such as a camera, or a wireless control system that enables the adjustment of one or more settings of the light fitting 50, such as the brightness, intensity and/or dimness of the light emitted from the light fitting 50. The wireless control system could be a smart gateway that enables remote access and control of the light fitting 50 via a mobile application, computer interface or web hosted portal. The smart gateway can act as a hub that facilitates connection of the light fitting 50 to other smart device(s), which can then in turn also be controlled through the smart gateway. The smart gateway may thus enable remote access to, and control of, multiple electrical devices in addition to the light fitting 50 itself. In some forms, some of the electrical devices that can be accessed and controlled via the smart gateway may be external to, and separate from, the light fitting 50.

100581 In some forms, the attachment 30 can comprise one or more of a router, a signal extender, a fan, and a spot light. In some forms, the attachment 30 can comprise a battery that provides power to the light fitting 50, for example in the event that the mains power is cut-off or fails, whereby the battery can power the light fitting 50 as an emergency lighting system. In some forms, the battery can draw electrical power from the light fitting 50 through the adapter 10 in order to recharge. In some forms, the attachment 30 can comprise a rechargeable battery that is removably retained at the attachment 30, and configured to be disconnected for use with a different electrical fitting or device. In some forms, the attachment 30"' can comprise a rechargeable battery module where the attachment 30"' is connected to one or more solar panels that generate and supply the electrical power necessary for the attachment 30"'to operate (e.g. Fig 14B). In some forms, the attachment 30 can comprise a control system that draws electrical power from the light fitting 50 and facilitates the remote control of other devices that are not in wired connection to the light fitting 50. In some forms, the attachment 30 can comprise one or more USB ports, where the USB ports can be facilitated to couple the attachment 30 to an external device. The USB port may facilitate the exchange or data, or be configured to charge the device coupled therein. In some forms, the attachment 30 can comprise one or more of an audio or voice speaker, Public Address system, or an alarm siren. In some forms, the attachment 30 can comprise an intercom system, which may include a microphone, or may be used in conjunction with a camera having a microphone.

10059] When the adapter 10 is secured to a light fitting 50 that is attached to a ceiling surface, the base of the adapter 10 is retained adjacent the ceiling surface. Each of the interchangeable attachments 30 are designed to be slidingly engaged with the adapter 10 from below. Therefore, even if the light fitting 50 is already mounted to the ceiling, an attachment 30 can still be attached or removed relatively easily.

100601 A fastener 40 can be used to further secure the selected attachment 30 to the adapter 10, preventing the attachment 30 from being slidingly removed. When the attachment 30 is in a mounted configuration to the adapter 10 (e.g. Fig 12), an attachment hole 38 through the side wall of the attachment 30 aligns with a corresponding adapter hole 19, the adapter hole 19 being formed along the sides of the rim 16 of the adapter 10. In some embodiments, one or both of the attachment hole 38 and adapter hole 19 can be internally threaded to receive and retain the fastener 40 therein without requiring the addition of a separate securing nut.

100611 In the manner described above, the disclosed adapter 10 performs as a socket interface, which when integrated with the light fitting 50 can facilitate engagement of one or more interchangeable attachments 30 to the light fitting 50. The adapter may thus improve the ease of with which a lighting system 100 can be customised.

100621 The adapter 10 can provide both an interface for engaging and retaining the one or more interchangeable attachment 30, as well as a conduit for electrical connectivity between the attachment 30 and the light fitting 50. One or more pairs of electrical contacts 63 can be embedded within an outer facing portion of the ridges 24, each of the electrical contacts 63 being wired through the adapter 10 to connection points 64 at the rear facing side 12 of the adapter 10 to a set of electrical wires 62. The electrical wires 62 derive electrical power from a driver 60 that is housed within the light fitting 50. The driver 60 converts the electricity entering the light fitting 50 from an external power source (e.g. the mains power) into useable electrical energy for powering the attachment 30. The terminal block connected to the driver 60 is covered by a terminal block cover 65 that houses the terminal block for improved safety. Each attachment 30 comprises a corresponding set of electrical contact points 36 that feed the electrical power therethrough to power the electronic components contained within the attachment 30.

100631 In a variation, adapter 10 is configured to function as a power outlet, or source or conduit, through which the one or more interchangeable attachments 30 that are engaged with the outward facing side 22 can receive power from or via, or provide power to, the light fitting 50. For example, the outward facing side of the adapter can be configured with a plurality of recessed contact points through which the engaged attachment can connect to the adapter in order to receive power from or via, or provide power to, the light fitting. In a further example, the outward facing side can comprise a socket for receiving a plug associated with the attachment. In a further variation, adapter can be configured to provide electrical power to the attachment wirelessly.

10064] In some forms, a set of the electrical contact points 36,63 can be used to facilitate the attachment 30 controlling the properties of the light, such as for example dimming the brightness.

100651 In some forms, the wiring for providing electrical power to the light fitting 50 can be run through the opening 56 at one of the first 53 or second 54 distal ends, and into the hollow interior portion of the light fitting 50. The adapter 10 and attachment 30 can thus be formed with a conduit entry point, with each of the adapter 10 and attachment 30 comprising a respective aperture 26,39 that aligns, and is located adjacent to one another, thereby forming together a substantially conjoined aperture.

100661 For example, referring to Figures 5 to 8, a circular aperture 26 can be formed that extends longitudinally through the adapter 10 from the outward facing side 22 to the rear facing side 12 of the adapter 10. The aperture 26 can be located in the portion of the generally planar surface that is proximal to the base of the adapter 10, and aligned centrally on the generally planar surface in a lateral direction. The attachment 30 comprises a corresponding U-shaped aperture 39, the aperture 39 extending through both the cover portion 32 and an internal portion 31 of the attachment, and being located such that the curved portion of the U-shape aligns with the circular aperture 26 of the adapter 10. A removable U-shaped cover 33 is configured to slot into, and be retained within, the U-shaped aperture 39 when the aperture 26,39 is not being used for access to the interior of the light fitting 50.

10067] As would be appreciated by one skilled in the art, in a variation, the features of the coupling mechanisms of each of the adapter 10 and attachment 30 disclosed within the present disclosure are to be considered non-limiting. The features of the coupling mechanisms can be formed to have a wide variety of different shapes and/or sizes, provided that the adapter 10 can be securely coupled to the attachment 30. For example, in a variation shown in Figures 16A to 16C, the overhanging flanges 25 as well as the corresponding grooves 35 can each be formed to have a relatively narrow width and depth therealong.

100681 In addition, the foregoing describes only some embodiments of the invention(s), and alterations, modifications, additions and/or changes can be made thereto without departing from the scope and spirit of the disclosed embodiments, the embodiments being illustrative and not restrictive.

100691 Furthermore, invention(s) have been described in connection with what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention(s). Also, the various embodiments described above may be implemented in conjunction with other embodiments, e.g., aspects of one embodiment may be combined with aspects of another embodiment to realize yet other embodiments. Further, each independent feature or component of any given assembly may constitute an additional embodiment.

10070] In the foregoing description of preferred embodiments, specific terminology has been resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar technical purpose.
