DETAILED DESCRIPTION
(12) It is to be understood that a light fixture is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The described embodiments are capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of including, comprising, or having and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms connected, coupled, and mounted, and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. In addition, the terms connected and coupled and variations thereof are not restricted to physical or mechanical connections or couplings.
(13) Turning to the Figures,
(14) The mounting base 30 may be electrically coupled to a junction box 1 on a ceiling 2, wall, or other structure. The light fixture housing 20 may rotate relative to the installed orientation of the mounting base 30 allowing the initial orientation of the junction box 1 and/or mounting base 30 to not limit the orientation of the subsequently attached light fixture housing 20. Additionally, the interface between the light fixture 20 and the mounting base does not require direct installation wiring and electrical connection and power for the fixture is supplied through the rotational quick connect construction. Further, the coupling of the light fixture housing 20 and mounting base 30 may allow adjustments to the rotation, mounting, and aiming of the fixture without breaking the electrical contact from the junction box 1 and/or connecting base 30.
(15) Multiple implementations may be appreciated for electrically connecting the mounting base 30 to the associated junction box 1 which provides power. In some implementations, the mounting base 30 may be hard wired directly to the hot, neutral and ground connections to the junction box. In other implementations, the junction box and the mounting base may be connected by quick connect mechanical connectors. In one of the examples and implementations, as is shown in
(16) The light fixture housing 20 may maintain rotationally exposed electrical connection to the mounting base 30 during rotation and between rotational orientations/adjustments. When assembled, the light fixture housing 20 may be electrically coupled regardless of the rotational orientation of the light fixture housing 20 relative to the mounting base 30. As such, the ground, neutral, and hot connections 32 may be electrically maintained for 360 degrees of rotation (e.g. CW and/or CCW) about an axis A. The electrical contacts/connectors 22 of the light fixture housing 20 may be mechanically and electrically coupled to the electrical contacts/connectors 32 of the mounting base 30 when assembled and/or locked in rotational position as shown in
(17) The electrical contacts or connections 32, 22 between the mounting base 30 and the light fixture housing 20 may be rotatably electrically engaged during the rotation (e.g. in the plurality of rotational orientations of the light fixture housing in respect to the base). As shown in
(18) For example, in the embodiment shown in
(19) In various constructions, the plurality of rings 33 of the mounting base may be installed within a corresponding number of annular extending grooves formed within the base to fixedly retain the rings therein. Further, the disc 34 may be centrally positioned within the annular grooves and the annular rings within a recess formed in the base 30. The recess and annular grooves form a mechanism to positionally retain both the annular rings and the disc within the base.
(20) Alternative constructions maintaining electrical connectivity between the housing 20 and the base 30 may be utilized which minimize the exposed surface of the wiring. For example, the embodiment of the light fixture 110 shown in
(21) Rotatable plug 132 which enters into receptacle 122 allows for electrical connectivity between the fixture and the base while preventing the necessity of actual wiring of the fixture. Further, in the various examples, electrical connectivity between the base and the electrical fixture may be maintained and be rotationally exposed about the entire 360 degrees of rotation there between. Thus, in some examples and implementations, the base 132 may include electrical contacts on a first and second surface of the annular ring of the base. The electrical contacts can be either on an upper surface or on a side surface one of the annular rings depicted in this one of several embodiments. For example, annular rings may be located along either a top surface of a wall on the base or along an interior or exterior wall surface. Each such annular ring may be rotationally exposed for connectivity by an engaging leaf spring or contact surface from a mating light fixture along an entire rotational extent between the fixture and mounting base. Alternatively, the rotational connectivity may be limited in radial extent or include electrically connected and disconnected radial positions.
(22) For example, annular walls may be utilized in
(23) A central post receiving receptacle could be provided in the base to receive a mating electrical contact from the light fixture 120 while also working in conjunction with additional contacts in the rotational plug. In some embodiments, opposite orientation structures could be provided such as providing the post receiving receptacle on the other structure and/or in combination with annular contact surfaces receiving and contacting electrical contacts on the annual surface of either of the base and light fixture. It should be understood a variety of rotatable electrical connections/couplings may be used between the light fixture housing and the mounting base and still be within the scope of the invention.
(24) In some implementations, the light fixture housing may be rotational secured in at least one rotational orientation relative to the mounting base. In the embodiments shown, a cam lock or latch may be used to lock or fix the rotational position. When in a disengaged position as shown in broken lines in
(25) In some embodiments, the light fixture 10, 110 may include a variety of water proofing features to reduce the flow of water into the light fixture and/or internally between structures of the components. Weather proofing and water proofing between the light fixture and the base may prevent moisture intrusion into the electrical connectivity and interface area providing electrical connection and power to the light fixture. Moisture intrusion into such areas could potentially cause corrosion or other issues related to the exposed electrical connecting structures. Various water prevention structures can be implemented in the interface areas between the two structures.
(26) For example, one or more seals or gaskets 80 may be used between the light fixture housing 20 and the mounting base 30. As shown in
(27) In some embodiments, one or more structures of the light fixture housing and/or mounting base may axially and/or rotationally engage each other to allow relative rotation and/or energizing of the light fixture housing. Alternatively, or in combination with the light fixture structure, the user may need to axially and/or rotationally maintain the light fixture housing with the mounting base until the rotational orientation is fixed.
(28) With the light fixture housing 20 assembled with the mounting base 30, the electrical connection 22, 32 may be engaged/energized. In some embodiments as shown in
(29) For example, in some embodiments, the rotational locking mechanism 70 (e.g. cam latch) may be used, alone or in combination with other structure (e.g. retention members), to axially and/or rotationally fix the light fixture housing to the mounting base. The cam latch/rotational lock 70 may be used to axially and/or rotationally fixate the light fixture housing with the mounting base. For example, the one or more rotational locks 70 (e.g. cam lock) may partially be inserted into an annular groove 61 in the outer periphery of the mounting base skirt 36 allowing axial retention while being able to rotate of the light fixture housing until the user decides to fully engage the cam latch to fix the rotational orientation. If no retention members are used, one or more rotational locks may be used alone to lock the axial and rotational position of the light fixture housing.
(30) In some implementations, the one or more retention members 50 may include one or more different retention members. The one or more retention members 50 may be different in shape, size, quantity, position, and construction. For example, as shown in
(31) As shown in the embodiments in
(32) In use, a user may insert the 120V AC wires 3, projecting from the junction box 1, into the reusable push-in wire connectors 40 on the bottom of the mounting base 30. The user may then mount the mounting base 30 to the junction box 1 with one or more fasteners. The light fixture housing 20 may then be engaged (e.g. axially) with the mounting base 30 without the need to handle wires or engage in wiring of a wiring interface between the base and the light fixture. In some embodiments, when axially engaged the one or more retention members 50 and/or rotational lock 70 may engage the annular groove 61 of the mounting base 30 thereby coupling the light fixture housing 20 with the mounting base 30 and/or the electrical connections 22, 32 therebetween. A characteristic of the correct engagement therebetween may be identified by the user such as an audible/visual indicator. With the one or more retention members 50, if used, engaged with the receivers 60/annular groove 61, the light fixture housing 20 is engaged (e.g. axially) such that the user may freely rotate the light fixture housing 20 relative to the fixed mounting base 30. Moreover, the light source/light fixture housing 20 may maintain the electrical coupling between the light fixture housing and the mounting base during the rotation of the light fixture housing. The user may rotate the light fixture housing to aim, orient features of the light fixture, etc. as desired by the application or user. Once the desired rotational orientation is achieved, the user may lock the rotational orientation via the cam lock or rotational lock/fastener 70. Subsequent rotational adjustments may be made merely by temporarily disengaging the rotational lock. Further, the user may desire to change to a different light fixture housing and still utilize the mounting base, make repairs, or change light sources by disengaging the light fixture housing.
(33) Moreover in some embodiments, if the one or more retention members 50, receivers 60, and/or rotational lock 70 are not used to engage (e.g. axially) the mounting base 30, the user may have to hold the light fixture housing 20 to the mounting base 30 while rotating into position or merely orientate before axial engagement before fixing the rotational orientation with the rotational lock 70.
(34) While several inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the invent of embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.
(35) All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms. The indefinite articles a and an, as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean at least one. The phrase and/or, as used herein in the specification and in the claims, should be understood to mean either or both of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases.
(36) Multiple elements listed with and/or should be construed in the same fashion, i.e., one or more of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the and/or clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to A and/or B, when used in conjunction with open-ended language such as comprising can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
(37) As used herein in the specification and in the claims, or should be understood to have the same meaning as and/or as defined above. For example, when separating items in a list, or or and/or shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as only one of or exactly one of, or, when used in the claims, consisting of, will refer to the inclusion of exactly one element of a number or list of elements. In general, the term or as used herein shall only be interpreted as indicating exclusive alternatives (i.e. one or the other but not both) when preceded by terms of exclusivity, such as either, one of, only one of, or exactly one of Consisting essentially of, when used in the claims, shall have its ordinary meaning as used in the field of patent law.
(38) As used herein in the specification and in the claims, the phrase at least one, in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase at least one refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, at least one of A and B (or, equivalently, at least one of A or B, or, equivalently at least one of A and/or B) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
(39) It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.
(40) In the claims, as well as in the specification above, all transitional phrases such as comprising, including, carrying, having, containing, involving, holding, composed of, and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases consisting of and consisting essentially of shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures.
(41) The foregoing description of methods and embodiments has been presented for purposes of illustration. It is not intended to be exhaustive or to limit the invention to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention and all equivalents be defined by the claims appended hereto.
