Embodiments described herein relate generally to luminaires, and more particularly to systems, methods, and devices for support brackets for lamp sockets of luminaires.
Recessed light fixtures are used in many residential, commercial, and industrial applications. Generally, the space in which to install a recessed light fixture is limited, and so the time to install a recessed light fixture can be increased when parts of the light fixture (e.g., the luminaire, the luminaire housing) are cumbersome to install.
In general, in one aspect, the disclosure relates to a bracket for a luminaire. The bracket can include a first portion that includes at least one first lamp socket connection system coupling feature disposed within a first body of the first portion, where the at least one first lamp socket connection system coupling feature is non-planar with the first body. The bracket can also include a second portion coupled to a proximal end of the body of the first portion, where the second portion includes at least one first housing coupling feature disposed within a second body of the second portion. The at least one first lamp socket connection system coupling feature can be configured to couple to at least one first bracket coupling feature of a socket of the luminaire. The at least one first housing coupling feature can be configured to couple to at least one second bracket coupling feature of a housing of the luminaire.
In another aspect, the disclosure relates to a bracket for a luminaire. The bracket can include a first portion having at least one first lamp socket connection system coupling feature and at least one spring clip coupling feature disposed within a first body of the first portion, where the at least one first lamp socket connection system coupling feature and at least one spring clip coupling feature are physically separated from each other by the first body. The bracket can also include a second portion coupled to a proximal end of the body of the first portion, where the second portion comprises at least one first housing coupling feature disposed within a second body of the second portion. The at least one first lamp socket connection system coupling feature can be configured to couple to a lamp socket connection system of the luminaire. The at least one first housing coupling feature can be configured to couple to at least one second bracket coupling feature of a housing of the luminaire.
In yet another aspect, the disclosure can generally relate to a luminaire. The luminaire can include a housing having a housing body with at least one housing wall having an inner perimeter that forms a cavity, where the at least one housing wall includes at least one first bracket coupling feature. The luminaire can also include a socket assembly disposed within the housing, where the socket assembly can include a socket and a socket holder having a main portion and at least one second bracket coupling feature positioned adjacent to the main portion, where the socket is coupled to the main portion of the socket holder. The luminaire can further include a bracket disposed within the cavity and coupled to the at least one housing wall and the socket assembly. The bracket can include a first portion having at least one lamp socket connection system coupling feature disposed within a first body of the first portion, where the at least one lamp socket connection system coupling feature is coupled to the at least one second bracket coupling feature, where the at least one first lamp socket connection system coupling feature is non-planar with the first body. The bracket can also include a second portion coupled to a proximal end of the body of the first portion, where the second portion comprises at least one first housing coupling feature disposed within a second body of the second portion, where the at least one first housing coupling feature is coupled to the at least one first bracket coupling feature.
These and other aspects, objects, features, and embodiments will be apparent from the following description and the appended claims.
The drawings illustrate only example embodiments of support brackets for lamp sockets of luminaires and are therefore not to be considered limiting of its scope, as support brackets for lamp sockets of luminaires may admit to other equally effective embodiments. The elements and features shown in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the example embodiments. Additionally, certain dimensions or positionings may be exaggerated to help visually convey such principles. In the drawings, reference numerals designate like or corresponding, but not necessarily identical, elements.
The example embodiments discussed herein are directed to systems, apparatuses, and methods of support brackets for lamp sockets. While the figures shown and described herein are directed to luminaires, example support brackets can also be used in other applications aside from luminaires, including but not limited to motor control centers, relay cabinets, gardening, and enclosures. Thus, the examples of support brackets (also referred to herein more simply as brackets) described herein are not limited to luminaires.
With respect to luminaires, while the example embodiments described herein are directed to recessed luminaires, example embodiments (or portions thereof) can also be used for non-recessed luminaires. Example luminaires can be used with one or more of a number of different types of lighting systems, including but not limited to light-emitting diode (LED) lighting systems, fluorescent lighting systems, organic LED lighting systems, incandescent lighting systems, and halogen lighting systems. Therefore, example embodiments described herein should not be considered limited to any particular type of luminaire or lighting system.
Any example support brackets (or portions (e.g., features) thereof) described herein can be made from a single piece (as from a mold). When an example support bracket (or portion thereof) is made from a single piece, the single piece can be cut out, bent, stamped, and/or otherwise shaped to create certain features, elements, or other portions of a component. For example, as discussed below, at least a portion of the support bracket can be made from a single sheet where various portions are cut out, bent, shaped, and otherwise manipulated to form an example support bracket.
Alternatively, an example support bracket (or portions thereof) can be made from multiple pieces that are mechanically coupled to each other. In such a case, the multiple pieces can be mechanically coupled to each other using one or more of a number of coupling methods, including but not limited to epoxy, welding, fastening devices, compression fittings, mating threads, and slotted fittings. One or more pieces that are mechanically coupled to each other can be coupled to each other in one or more of a number of ways, including but not limited to fixedly, hingedly, removeably, slidably, and threadably.
Components and/or features described herein can include elements that are described as coupling, fastening, securing, aligning, or other similar terms. Such terms are merely meant to distinguish various elements and/or features within a component or device and are not meant to limit the capability or function of that particular element and/or feature. For example, a feature described as a “coupling feature” can align, abut against, receive, be disposed within, and/or perform other functions aside from physically attaching (e.g., fasten, secure). In addition, each component and/or feature described herein can be made of one or more of a number of suitable materials, including but not limited to metal, rubber, and plastic.
A coupling feature (including a complementary coupling feature) as described herein can allow one or more components and/or portions of an example support bracket to become mechanically coupled, directly or indirectly, to a portion (e.g., a housing, a finishing section, a lamp socket) of a luminaire and/or to another portion of the support bracket. A coupling feature described herein can include, but is not limited to, a portion of a hinge, an aperture (as shown), a slot, a spring clip, a tab, a detent, a recess, a clamp, and a mating thread. An example support bracket can be coupled to a frame, a housing, and/or another component of a luminaire by the direct use of one or more coupling features. In addition, or in the alternative, an example support bracket can be coupled to a housing, a finishing section, a lamp socket, and/or another component of a luminaire using one or more independent devices that interact with one or more coupling features disposed on the example support bracket, housing, finishing section, lamp socket, and/or other component of a luminaire. Examples of such devices can include, but are not limited to, a pin, a hinge, a fastening device (e.g., a bolt, a screw, a rivet), and a spring. One coupling feature described herein can be the same as, or different than, one or more other coupling features described herein.
As described herein, a user can be any person that interacts with an example support bracket. Examples of a user may include, but are not limited to, an engineer, an electrician, a maintenance technician, a mechanic, an operator, a consultant, a contractor, a homeowner, and a manufacturer's representative.
The components of example support brackets described herein can be physically placed in outdoor environments. In addition, or in the alternative, example support brackets can be subject to extreme heat, extreme cold, moisture, humidity, high winds, dust, and other conditions that can cause wear on the support brackets, or portions thereof. In certain example embodiments, the portions of support brackets, as well as any coupling (e.g., mechanical, electrical) between such portions, are made of materials that are designed to maintain a long-term useful life and to perform when required without mechanical failure.
In one or more example embodiments, when the support brackets described herein are part of a luminaire, one or more components of the luminaire is subject to meeting certain standards and/or requirements. For example, the American Society of Testing and Materials (ASTM) creates, maintains, and publishes standards that apply to luminaires. For example, the ASTM publishes ASTM E283-04, which is a standard test method for determining rate of air leakage through exterior windows, curtain walls, and doors under specified pressure differences across the specimen. In other words, a luminaire is able to meet various standards that apply to the luminaire when example support brackets are used therein.
Examples of other authorities setting standards and/or regulations that can apply to example luminaires can include, but are not limited to, the National Electric Code (NEC), the Canadian Electric Code (CEC), the International Electrotechnical Commission (IEC), the International Energy Conservation Code (IECC), and Underwriter's Laboratories (UL). As used herein, an air-tight seal describes a seal between two or more coupling features of an example luminaire that allows the luminaire to meet ASTM E283-04 and/or any equivalent thereof. In other words, the term “air-tight seal” used herein is not taken literally, but rather is defined in context of ASTM E283-04 and/or any equivalent thereof.
Any component described in one or more figures herein can apply to any subsequent figures having the same label. In other words, the description for any component of a subsequent (or other) figure can be considered substantially the same as the corresponding component described with respect to a previous (or other) figure. The numbering scheme for the components in the figures herein parallel the numbering scheme for the components of previously described figures in that each component is a three or four digit number having the identical last two digits.
Example embodiments of support brackets will be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of support brackets are shown. Support brackets may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of support brackets to those of ordinary skill in the art. Like, but not necessarily the same, elements (also sometimes called components) in the various figures are denoted by like reference numerals for consistency.
Terms such as “first,” “second,” “top,” “bottom,” “side,” “upward,” “downward,” “distal”, “left,” and “right” are used merely to distinguish one component (or part of a component or state of a component) from another. Such terms are not meant to denote a preference or a particular orientation. Also, the names given to various components described herein are descriptive of example embodiments and are not meant to be limiting in any way. Those skilled in the art will appreciate that a feature and/or component shown and/or described in one embodiment (e.g., in a figure) herein can be used in another embodiment (e.g., in any other figure) herein, even if not expressly shown and/or described in such other embodiment.
For example, if the outer perimeter of the socket body 107 has mating threads 108 disposed thereon, then the inner surfaces of the walls 164 have a screw shell 162 (sometimes called mating threads) disposed thereon that are configured to couple to the mating threads 108 of the light source 105. As another example, if the top surface of the socket body 107 is an electrical contact 109, then the inner surface of the socket body 160 includes an electrical contact that complements the electrical contact 109. The light source 105, when coupled to the socket assembly 150, is disposed within a cavity 119 formed by the reflector body 114.
The light source 105 can use any type of lighting technology. Examples of such lighting technologies can include, but are not limited to, light emitting diode (LED), halogen, incandescent, sodium vapor, and mercury vapor. As shown in
The socket assembly 150 can have one or more coupling features 151 (in this case, an aperture) disposed in the top surface of the socket receiver body 160 to couple, directly or indirectly, to one or more complementary coupling features 158 (in this case, an aperture) disposed in the main body 156 of the spring clip 155. In addition, the top surface of the socket receiver body 160 can have one or more other coupling features 159 (in this case, tabs) that couple, directly or indirectly, to an outer side surface of the socket receiver body 160 (in this case, a recess).
On either side of the main body 156 of the spring clip 155 is a side body 157 that includes a receptacle coupling feature 185 that couples, directly or indirectly, to a complementary coupling feature 113 disposed in the receptacle 112. In this case, each receptacle coupling feature 185 is a clip, and each coupling feature 113 is an aperture into which a portion of the receptacle coupling feature 185 is disposed. The coupling feature 113 of the receptacle 112 can have one or more of a number of features. For example, the coupling feature 113 can include a tab that defines the aperture formed by the coupling feature 113. Each receptacle coupling feature 185 has various features, such as a top protrusion 187, a bottom protrusion 186, a tab 189, and an apex 188 where the top protrusion 187 and the bottom protrusion 186 meet.
A bottom extension 163 can extend from the bottom protrusion 186 of the receptacle coupling feature 185 and can be substantially planar with the side body 157. The tab 189 can extend from the top protrusion 187 and/or the bottom protrusion 186 in any of a number of directions (e.g., substantially parallel with the side body 157, as shown in
Because of the spring-like nature of the spring clip 155, each side body 157 (and, thus, each receptacle coupling feature 185) can move relative to the main body 156. To move a side body 157 inward, an inward force is applied to the side body 157. When that inward force is removed, the side body 157 returns to its natural position relative to the main body 156. When the spring clip 155 is coupled to the socket assembly 150, one or more features (e.g., protrusion 165) of the socket assembly 150 can limit the inward travel of a side body 157 of the spring clip 155. Further, as described below with respect to
When the spring clip 155 is positioned relative to the receptacle 112 as shown in
Further, in this case, the body 123 of portion 121 and the body 135 of portion 122 are long and flat. As shown in
In certain example embodiments, the orientation of portion 121 relative to portion 122 can be based on one or more of a number of factors. Such factors can include, but are not limited to, the characteristics (e.g., size, shape) of the finishing section (e.g., reflector body 114) of the luminaire or portion thereof (e.g., reflector assembly 100), the location of coupling features in the finishing section, the characteristics (e.g., size, shape, weight) and of the lamp socket connection system (e.g., lamp socket connection system 101), the characteristics (e.g., size, shape, orientation) of the coupling features (e.g., coupling features 185) of the lamp socket connection system, the characteristics (e.g., size, shape, weight) and of the finishing section, and the characteristics (e.g., size, shape, orientation) of the coupling features of the finishing section of the luminaire.
Each portion of the bracket 120 can include one or more coupling features for coupling the bracket 120 to one or more other components (e.g., finishing section, housing, lamp socket connection system) of the luminaire or portions (e.g., reflector assembly 100) thereof. For example, the portion 121 of the bracket 120 shown in
In certain example embodiments, the characteristics (e.g., size, shape, orientation) of the socket receiver coupling features 125 are designed to complement one or more coupling features of a socket receiver (e.g., socket assembly 150). In this case, there is one socket receiver coupling feature 125 that is an aperture 130 formed by an outer perimeter 129 and that traverses the thickness of the body 123 of portion 121. The shape and size of the aperture 130 can be substantially the same as, or slightly larger than, the shape and size of a portion (e.g., walls 164 at the distal end) of a socket receiver (e.g., socket assembly 150) that is disposed within the aperture 130 when the socket receiver is coupled to the socket receiver coupling feature 125. In this case, the aperture 130, when viewed from above, is circular in shape.
In certain example embodiments, the characteristics (e.g., size, shape, orientation) of the spring clip coupling features 124 are designed to complement one or more coupling features (e.g., coupling features 185) of a spring clip (e.g., spring clip 155). In this case, there are two spring clip coupling features 124 shown in
The tabs 128 are examples of features of the spring clip coupling features 124 that are not present in the currently-available art. The tabs 128 (or alternative features such as roll-overs, bend-downs, and bend-ups, as described below), by being non-planar with the body 123 of portion 121, allow for more stability and less wobbling between the bracket 120 and the lamp socket connection system 101. Specifically, the tabs 128 engage with the coupling features 185 of the spring clip 155 to stabilize the lamp socket connection system 101 relative to the bracket 120. By contrast, in the current art, the lamp socket connection system 101 has little stability, resulting in wobbling of the lamp socket connection system 101.
The shape and size of the aperture 131 of each spring clip coupling feature 124 can be suitable to receive, couple to, and release a coupling feature (e.g., coupling feature 185) of a spring clip. In this case, the aperture 131, when viewed from above, is “T” shaped, and would be rectangular if not for the tabs 128. When there are multiple spring clip coupling features 124, as in this case, the spring clip coupling features 124 can be oriented in one of a number of ways with respect to each other. For example, in this case, the two spring clip coupling features 124 are oriented as mirror images and are equidistantly spaced with respect to the center of the socket receiver coupling feature 125.
In certain example embodiments, rather than having separate spring clip coupling features 124 and socket receiver coupling features 125, as with the bracket 120 of
In certain example embodiments, the characteristics (e.g., size, shape, orientation) of the finishing section coupling features 126 are designed complement one or more coupling features of a finishing section (e.g., reflector, baffle, trim, gimble) of a luminaire. In this case, there are two finishing section coupling features 126 shown in
When there are multiple finishing section coupling features 126, as in this case, the finishing section coupling features 126 can be oriented in one of a number of ways with respect to each other. For example, in this case, the two finishing section coupling features 126 are oriented as mirror images and are equidistantly spaced with respect to the center of the socket receiver coupling feature 125. In certain example embodiments, the various coupling features of portion 121 are oriented as shown in
Since portion 121 can support a number of components (e.g., finishing section, light source, lamp socket connection system 101), portion 121 and/or portion 140 can include one or more reinforcement features 127 that help stiffen or otherwise strengthen the bracket 120 so that the bracket 120, or portions thereof, do not become deformed when coupled to other components of the luminaire. For example, the outer sides of body 123 of portion 121 can have reinforcement features 127 in the form of lips. In such a case, the lips 127 can be bent at some angle (e.g., 90°) downward (as shown in
As discussed above, in certain example embodiments, portion 122 of the bracket 120 can also include one or more coupling features. For example, as shown in
Since portion 122 is coupled to portion 121 and can support portion 121 and any components (e.g., finishing section, light source, lamp socket connection system 101) coupled thereto, portion 122 can include one or more reinforcement features 127 that help stiffen or otherwise strengthen the bracket 120 so that the bracket 120, or portions thereof, do not become deformed when coupled to other components of the luminaire. For example, the outer sides of body 135 of portion 122 can have reinforcement features 137 in the form of lips. In such a case, the lips 137 can be bent at some angle (e.g., 90°) downward (as shown in
In certain example embodiments, portion 140 of the bracket 120 can also include one or more coupling features. For example, as shown in
Referring to
In this case, as shown in
In addition, the combination of the wall 164 and the protrusion 165 described above with respect to
Referring to
In addition, portion 521 of the bracket 520 does not have any lips, as with the lips 127 of the bracket 120 described above. Instead, there are a number of ribs 547 that protrude from the body 523 of portion 521 increase the strength of portion 521. Also, the finishing section coupling features 526, while still having a keyhole shape, are oriented differently with respect to the socket receiver coupling feature 525 when compared with the orientation of the finishing section coupling features 126 relative to the socket receiver coupling feature 125 for the bracket 120 described above.
Further, the housing coupling feature 536 of portion 522 of the bracket 520 of
The coupling features 675 can be adjustable and/or otherwise flexible so that the finishing section 680 is suspended in a certain position relative to one or more other components (e.g., the housing 630, the bracket 620, the light source 605) of the luminaire 674. In this case, the coupling features 675 include one or more springs 677 that include a bracket coupling feature 678 at its top end and a finishing section coupling feature 679 at its bottom end. The bracket coupling feature 678 of the coupling feature 675 couples to the finishing section coupling features 626 of the bracket 620, and the finishing section coupling feature 679 of the coupling feature 675 couples to a coupling feature 681 of the finishing section 680.
Contrasting with the reflector assembly 100 of
The rectangular tabs 744 of the spring clip coupling features 724 can be bent downward (as shown in
In such a case, if the receptacle coupling feature is configured similar to the receptacle coupling feature 185 of
Certain example embodiments provide a number of benefits. Examples of such benefits include, but are not limited to, use of fewer materials, simplified installation, simplified inspection, simplified maintenance, installation of a luminaire in relatively small spaces, and reduced cost. Example brackets described herein also allow for increased flexibility for manufacturing, installing, and/or maintaining a luminaire. In addition, example brackets allow for ease of installation while providing an air-tight condition for the luminaire. Example embodiments can also be used to assist with thermal management and/or shielding for the luminaire.
