DETAILED DESCRIPTION

[0030] Historically, LED drivers have been designed to be mounted inside of a luminaire, which increases the overall size and weight of the luminaire. This in turn increases costs due to structural and/or thermal needs of the luminaire. In addition, having separate components and/or modules such as, for instance, surge protection, dimming controls, daylight sensors, LED drivers, all as individual components makes wiring a significant challenge, increasing cost further. In addition, replacement of failed electronic components within a luminaire can be quite time consuming and/or costly, largely due to having a skilled technician manually rewire these components. In view of the foregoing, various embodiments and implementations of the present invention are directed to modular sockets and components that can be removably plugged into these modular sockets.

[0031] Referring to FIG. 1, in one embodiment, a lighting assembly 100 includes a luminaire 102 that includes one or more light sources 104. In FIG. 1, one or more light sources 104 include a plurality of LEDs. However, this is not meant to be limiting. As noted previously, any type of light source, such as fluorescent, halogen, incandescent, and so forth, may be employed, alone or in combination with other types of light sources, as part of luminaire 102.

[0032] A modular socket 106 configured with selected aspects of the present disclosure is depicted as part of luminaire 102 in FIG. 1. FIG. 1 is a schematic drawing, so the fact that modular socket 106 is depicted entirely within the dashed line forming luminaire 102 should not be taken as limiting. Modular socket 106 may have an outer surface that protrudes from a luminaire housing (not depicted), is recessed into a luminaire housing, is flush with a luminaire housing, and so forth.

[0033] In various embodiments, modular socket 106 may include a housing 108 that may be constructed with various materials or combinations of materials, including but not limited to polymers, metals, rubbers, etc. Modular socket 106 may also include a power input interface 110 (e.g., which may support up to 480V in some embodiments) to receive a supply voltage 112. In FIG. 1, supply voltage 112 includes a hot wire 114, a neutral wire 116, and a ground wire 118. One or more of wires 114-118 may be omitted in other embodiments. Supply voltage 112 may be, for instance, alternating current (A/C) received from A/C mains, and may provide various magnitudes of voltages, such as anywhere from 120V to 480V, or any other high voltage value.

[0034] Modular socket 106 may also include a power output interface 120 electrically coupled within housing 108 with power input interface 110. In various embodiments, the coupling of power output interface 120 and power input interface 110 may be implemented using wires, via solid conductive paths (e.g., using copper or other conductive materials), and so forth.

[0035] Power output interface 120 may be electrically coupled with a power input interface 122 of an LED driver 124. Supply voltage 112 may be routed by modular socket 106 from its source (e.g., AC mains) to LED driver 124. LED driver 124 may receive this supply power, convert it to direct current (DC) if applicable, modulate the directed current based on various factors, and provide the modulated direct current through an LED output interface 126 to an LED control input interface 128 of modular socket 106. LED control input interface 128 may be electrically coupled with one or more LEDs 104 via one or more control lines 130, 132 (e.g., positive and negative control lines). By this electrical path, modular socket 106 may route the modulated direct current (or alternating current in some cases) to one or more light sources 104.

[0036] In some embodiments, modular socket 106 and/or LED driver 124 may include a removable health monitoring component 131 that, when triggered, causes modular socket 106 (or LED driver 124 as the case may be) to provide audible or visual output of a fault. For example, removable health monitoring component 131 may include a fuse or other electrical component that is destroyed or damages under certain circumstances, such as lighting strike, short circuit, malfunction of one or more components, improper polarity between internal components (i.e., improper installation), lack of LED driver 124, etc. In some embodiments, modular socket 106 and/or LED driver 124 may include an indicator such as a circumferential light source 133 that emits light of a certain color, intensity, or modulated pattern to indicate to a passerby that some portion of the assembly 100 is malfunctioning and/or needs to be replaced. Although circumferential light source 133 is depicted as part of socket 106, this is not meant to be limiting. In various embodiments, a light source may be additionally or alternatively disposed on other components, such as LED driver 124.

[0037] In various embodiments, modular socket 106 and/or LED driver 124 may include one or more mechanical engagement structures, two of which are depicted at 134A and 134B. These structures may take various forms and may be disposed at various positions of modular socket 106 and/or LED driver 124. For example, one or more of these structures 134 may be disposed on housing 108 of modular socket 106. Additionally or alternatively, one or more of these mechanical engagement structures 134 may be disposed on a housing 136 of LED driver 124, e.g., proximate a portion of LED driver (bottom in FIG. 1) that is designed for engagement with modular socket 106.

[0038] In various embodiments, mechanical engagement of one or more of the mechanical engagement structures 134 with one or more corresponding mechanical engagement structures 134 of LED driver 124 may simultaneously effect electrical coupling between (a) power output interface 120 of modular socket 106 and power input interface 122 of the LED driver, and (b) LED control input interface 128 and LED output interface 126 of LED driver 124. For example, in some embodiments, once LED driver housing 136 is brought into sufficient proximity of, or even into physical contact with, housing 108 of modular socket 106, one or both of LED housing 136 and housing 108 of modular socket 106 may be rotated, pressed, or otherwise mechanically influenced in order to mechanically engage (e.g., lock, secure) structures 134 of LED driver housing 136 with housing 108 of modular socket 106. This mechanical influencing may ensure that electrical contacts (e.g., 122, 126) of LED driver 124 are properly and securely electrically coupled with corresponding electrical contacts (e.g., 120, 128) of modular socket 106.

[0039] LED driver 124 may modulate direct current provided to one or more light sources 104 in various ways based on a variety of different signals. Many of these signals may be generated by a variety of different types of sensors. In FIG. 1, for instance, a first sensor 140 is operably coupled to a top of LED driver 124 by way of a socket 142. Socket 142 may take various forms, such as a socket that is in conformance with one or more books of the Zhaga Standard (https://www.zhagastandard.org/), a universal serial bus (USB) socket, or any other type of socket connection that is usable to transfer data and, where applicable, power. In various implementations, sensors can be removably replaced at socket 142 as desired. While one socket 142 is depicted on LED driver 124 in FIG. 1, this is not meant to be limiting. In various embodiments, any number of sockets, which may be the same as or different from each other, may be provided on housing 136 of LED driver 124.

[0040] Socket 142 may operably couple first sensor 140 (or whatever other sensor may be installed in socket 142) with a sensor bus 144 that may include one or more wires 146, 148 that may correspond to, for instance, positive and negative sensor terminals or contacts. Sensor bus 144 may be effectively extended into an interior of housing 108 of modular socket 106 by way of electrical coupling of a sensor output interface 150 of LED driver 124 with a sensor input interface 152 of modular socket 106. Sensor bus 144 may extend from modular socket 106 into, for instance, a second sensor 154.

[0041] First sensor 140 may take various forms. In some embodiments, first sensor 140 may be a daylight sensor that is configured to provide a signal indicative of light it senses. This signal may be used by LED driver 124, for instance, to determine whether to illuminate one or more light sources 104 of a streetlamp, to select a level of intensity to emit from one or more light sources 104, to select one or more colors of light to be emitted by one or more light sources 104, to select one or more light modulated patterns (e.g., coded light) to be emitted by one or more light sources 104, and so forth. Other types of sensors may also be affixed to housing 136 of LED driver 124, including but not limited to traffic sensors, presence sensors, IoT communication components (e.g., to communicate wirelessly with passing vehicles or pedestrians), thermometers, barometers, or other components such as fault lights, indicators, etc.

[0042] Like first sensor 140, second sensor 154 may take various forms. In some embodiments in which luminaire 102 is part of a streetlamp, first sensor 140, when mounted on top of LED driver 124 as shown in FIG. 1, may not face a street surface below. Accordingly, second sensor 154 (which in this example may be a presence sensor or traffic sensor) may be positioned on the lamppost, e.g., on a vertical post or on the bottom of a horizontal post on which luminaire 102 is mounted, so that second sensor 154 has a view of the street below.

[0043] FIGS. 2A-C schematically depict example use cases that demonstrate how a modular socket configured with selected aspects of the present disclosure may be deployed in various scenarios. In FIG. 2A, a lamppost 260 such as a streetlamp includes a vertical post 262 and a horizontal bar 264 extending therefrom. Inside of vertical post 262 is a high voltage power supply 212 that may share various characteristics with element 112 in FIG. 1. Power supply 212 extends from a power source (not depicted) to a first modular socket 206A that is situated on top of vertical post 262. A first LED driver 224A is secured to first socket 206A. First modular socket 206A is operably coupled with one or more control lines 230 for routing direct current generated by first LED driver 224A to other components, such as one or more light sources 204 of a luminaire 202 disposed on horizontal bar 264.

[0044] Additionally or alternatively, in some embodiments, a second modular socket 206B may be disposed on top of luminaire 202. In some embodiments, both first and second modular sockets 206A, 206B may be present. In other embodiments, only one or the other is present. A second LED driver 224B is installed on second modular socket 206B. Attached to second LED driver 224B is a first sensor 240A, which may be, for instance, a daylight sensor, a wireless communication component, etc. A second sensor 240B is attached to an underside of luminaire 202 and may take the form of, for instance, a traffic or presence sensor. As shown, second sensor 240B is operably coupled second LED driver 224B by way of control lines 230. In some embodiments, in addition to or instead of sensors 240A-B, a third sensor 240C may be attached remotely from any LED drivers, such as on vertical post 262.

[0045] In some implementations, rather than (or in addition to) third sensor 240C, another modular socket could be disposed near a bottom of vertical post 262 so that the modular socket is easily reachable. In this way, an LED driver or another component could be relatively easily replaced, e.g., without requiring equipment to raise a technician up high. Mounting a modular socket at such a low position, and having a single modular socket direct power to multiple luminaires/LED drivers, may be particularly advantageous with relatively tall lighting fixtures, such as some lamps that are used to illuminate highways, stadium lights, or other similar lighting assemblies in which the luminaires are difficult to reach and/or numerous. If the low-positioned LED driver or modular socket is vandalized, that may be detected, for instance, by health monitoring component 131, which may raise an alarm over one or more networks or via a flashing light (e.g., from circumferential light source 133).

[0046] FIG. 2B depicts an example in which a modular socket 206 configured with selected aspects of the present disclosure is mounted to a wall 268. Although not depicted in FIG. 2B, modular socket may include the various interfaces shown in FIG. 1, and thereby may be operably and/or electrically coupled with various remote components, such as one or more ceiling luminaires, wall-mounted luminaires, etc. An LED driver 224 is depicted installed on modular socket 206. LED driver 224 may be easily installed and/or replaced by virtue of mechanical engagement (or disengagement) with modular socket 206. Moreover, if mounted low enough on wall 268, a person can easily reach LED driver 224 to, for instance, install one or more sensors (e.g., presence sensors to turn on a ceiling light when a person walks by). FIG. 2C depicts an alternative example in which an LED driver 224 is installed in a modular socket (not visible from the perspective of FIG. 2C) that is disposed on a junction box 272.

[0047] FIG. 3 depicts a perspective view of both an example modular socket 306 and an example LED driver 324 configured with selected aspects of the present disclosure. FIG. 4 depicts the modular socket 306 from a different perspective. Turning to LED driver 324 first, LED driver 324 includes a housing 336 and an interface portion 380 at one end of housing 336. Interface portion 380 includes components that are configured for electrical coupling with corresponding components of modular socket 306 and components that are configured for mechanical engagement with corresponding components of modular socket 306.

[0048] LED driver 324 includes a power input interface 322 in the form of three metallic prongs that act as a male portion of a socket connection between LED driver 324 and modular socket 306. More or less prongs may be provided. In some embodiments, power input interface 322 of LED driver may take the form of a National Electric Manufacturers Association (NEMA) compliant plug, although this is not required. LED driver 324 also includes one or more sensor output interfaces 350 that may share one or more characteristics with sensor output interface 150 of FIG. 1.

[0049] A bottom surface of modular socket 306 is visible in FIG. 3, revealing various components of modular socket 306. These include, for instance, a power input interface 310 that shares one or more characteristics with power input interface 110 in FIG. 1. In particular, three electrical pathways are visible in FIG. 3, corresponding to the three male prongs of LED driver 324. Also visible in FIG. 3 are one or more wires 346, 348 (which more generally can be conductive paths) that may correspond to, for instance, positive and negative sensor terminals or contacts (e.g., 146, 148 in FIG. 1).

[0050] A variety of mechanical engagement elements 334 are also visible in FIG. 3. In some embodiments, a mass of LED driver 324 may be substantially or entirely supported by the mechanical engagement of mechanical engagement elements 334A-B of modular socket 306 with corresponding mechanical engagement elements 334C-E of LED driver 324. In some embodiments, the one or more mechanical engagement and locking structures 334 may include a plurality of mechanical engagement and locking structures 334A-D positioned and spaced around perimeters of housings 308, 336. More or less mechanical engagement and locking structures 334 may be provided, and may be referred to herein alternatively as mechanical engagement structures.

[0051] For example, LED driver 324 may be brought into close physical proximity with, or even physical contact with, modular socket 306. This may cause, for instance, mechanical engagement element 334A of modular socket 306, which protrudes from housing 308 of modular socket 306, to enter into mechanical engagement element 334C of LED driver 324, which takes the form of a recess. Similarly, this may also cause mechanical engagement element 334B of modular socket 306, which once again protrudes from housing 308 of modular socket 306, to enter into mechanical engagement element 334D of LED driver 324, which takes the form of another recess. In some such embodiments, housing 336 of LED driver 324 may then be rotated somewhat to further engage and lock these mechanical engagement elements together.

[0052] FIG. 4 depicts a top side of modular socket 306. LED driver 324 is not depicted in FIG. 4. In FIG. 4, a power output interface 320 includes three female contacts or recesses for receiving the three male prongs 322 of LED driver 324 that were visible in FIG. 3. Similarly, an LED input interface 328 (similar to interface 128 of FIG. 1) and a sensor input interface 352 of modular socket 306 are visible and are configured for electrical coupling with elements 326, 350 visible in FIG. 3. In some embodiments, female contacts/recesses of power output interface 320 may be larger than the male prongs depicted in FIG. 3, so that when housing 336 of LED driver 324 is rotated relative to housing 308 of modular socket 306, the prongs have room to maneuver or provide for a polarity-locking mechanism.

[0053] 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 inventive 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.

[0054] 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.

[0055] 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.

[0056] 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. 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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, Section 2111.03. It should be understood that certain expressions and reference signs used in the claims pursuant to Rule 6.2(b) of the Patent Cooperation Treaty (PCT) do not limit the scope.
