The present technology relates to lighting systems and more particularly to a conduit connector system for connecting an electrical supply to a light fixture.
Installation of conventional light fixtures in cramped spaces is often challenging due to fixture size and awkward electrical connections. With conventional technology, a connection between an electrical supply and a light fixture housing can be unwieldy due to jutting connectors extending beyond available space. For example, sockets or receptacles for receiving wires that provide power supply to the light fixture may be located at a top surface of the light fixture facing upwards. Accordingly, a conduit carrying electrical wires may be positioned either vertically or at a 45 degree angle above the light fixture for easy coupling with the sockets or receptacles located on the top surface of the light fixture. The vertical or angled entry of the conduit above the light fixture may require a larger plenum space for installation of the light fixture.
Further, conventional connector systems that provide electrical power to the light fixtures may not offer a quick connect and disconnect of the electrical supply to the light fixtures. For example, with conventional connection systems, such as stab lock or push-in connectors, a customer may have to use both hands to make a connection, i.e., one hand to hold the socket portion and another hand to push-in/plug the wires into the socket portion. Alternately or in addition, conventional connector systems may require a customer to use tools for connecting an electrical supply to the light fixtures. The above-mentioned approaches to connect an electrical supply to the light fixture may be time consuming, unwieldy, and inconvenient to a customer.
Therefore, in light of the above shortcomings, improved technology for connecting lighting fixtures to electrical supplies is needed. In particular, need exists for a light fixture connection system that is low profile and suited for deployment in a plenum that is shallow or otherwise space-restricted. Further, need exists for a light fixture connection system that is quick-connect or quick-disconnect, and allows tool-less installation. A capability addressing one or more such needs, or some other related deficiency in the art, would support lighting systems in multiple applications and deployment scenarios.
In one aspect, the present disclosure can relate to a connector system. The connector system includes a conduit connector that is configured to connect to a light module of a light fixture to provide electrical power to the light module. The conduit connector includes a housing assembly. In particular, the housing assembly is configured to overlappingly receive and retain an end of a conduit at one end of the housing assembly. The conduit may carry electrical wires. Further, the conduit connector includes one or more wire connectors disposed in the housing assembly at an opposite end of the housing assembly such that at least a portion of the one or more wire connectors projects out from the housing assembly and forms a substantially right angle with the housing assembly. The one or more wire connectors are configured to be coupled to the electrical wires carried by the conduit. In addition to the conduit connector, the connector system includes a locking clip that is coupled to the light module and configured to connect the conduit connector to the light module. The locking clip includes two arms with one or more being flexible. The two arms securely retain the housing assembly of the conduit connector when the conduit connector is connected to the light module. Further, the conduit connector is configured to connect to the light module by matingly engaging the portion of the one or more wire connectors that projects out from the housing assembly with respective wire connector receptacles disposed in the light module.
In another aspect, the present disclosure can relate to a conduit connector that includes a housing assembly and one or more wire connectors. The housing assembly is configured to overlappingly receive and retain an end of a conduit at one end of the housing assembly. The conduit carries electrical wires. Further, the one or more wire connectors disposed in the housing assembly at an opposite end of the housing assembly such that at least a portion of the one or more wire connectors projects out from the housing assembly and forms a substantially right angle with the housing assembly. The one or more wire connectors are configured to be coupled to the electrical wires, and the conduit connector is configured to connect to a light module of a light fixture to provide electrical power to the light module.
In yet another aspect, the present disclosure can relate to a connector system. The connector system includes a conduit connector that is configured to connect a conduit to a light module of a light fixture. The conduit connector includes a housing assembly that comprises a top housing and a bottom housing that is coupled to the top housing using one or more fasteners. Each of the top housing and the bottom housing includes a conduit receiving portion that is configured to receive and retain a portion of the conduit. Further each of the top and bottom housing includes a wire connector portion that is configured to house one or more wire connectors in vertical orientation such that a portion of the one or more wire connectors projects out from the housing assembly and forms a substantially right angle with at least one of the housing assembly and the conduit.
These and other aspects, objects, features, and embodiments will be apparent from the following description and the appended claims.
The foregoing and other features and aspects of the disclosure are best understood with reference to the following description of certain example embodiments, when read in conjunction with the accompanying drawings, wherein:
The drawings illustrate only example embodiments of the disclosure and are therefore not to be considered limiting of its scope, as the disclosure 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 positioning may be exaggerated to help visually convey such principles.
In the following paragraphs, the present disclosure will be described in further detail by way of examples with reference to the attached drawings. In the description, well known components, methods, and/or processing techniques are omitted or briefly described so as not to obscure the disclosure. As used herein, the “present disclosure” refers to any one of the embodiments of the disclosure described herein and any equivalents. Furthermore, reference to various feature(s) of the “present disclosure” is not to suggest that all embodiments must include the referenced feature(s).
The present disclosure is directed to a low-profile conduit connector system (herein “connector system”) for providing electrical power supply to a light fixture. The connector system includes a conduit connector. In particular, the conduit connector includes a housing that is divided into a wire connector portion and a conduit receiving portion. The conduit receiving portion of the housing overlappingly receives and securely retains an end of a conduit such that the conduit terminates in the housing. The opposite end of the conduit may be connected to an external power supply source or a junction box, and the conduit may carry electrical power supply wires (herein “electrical wires”) from the external power supply source or junction box to the housing. Further, the wire connector portion of the housing accommodates one or more wire connectors such that a portion of the one or more wire connectors projects out from underneath the housing forming a substantially right angle with the housing and/or the conduit. The one or more wire connectors are coupled to the electrical wires that are carried by the conduit and enter the housing via the conduit.
Furthermore, the connector system may include a light fixture part that is positioned on a light module of the light fixture and includes one or more wire connector receptacles and/or a locking clip. In particular, the one or more wire connector receptacles are disposed within a housing assembly of the light module such that they face an upward direction and a top end of the one or more wire connector receptacles is flush with an opening on a top surface of the light module. The locking clip is disposed on and coupled to the top surface of the light module such that an opening of the locking clip axially aligns with the opening on the top surface of the light module that is flush with the top end of the one or more wire connector receptacles. In other words, the opening of the locking clip exposes the top end of the one or more wire connector receptacles. In addition to the opening, the locking clip has two arms that are disposed on opposite sides of the opening. One or more of the arms are flexible such that they bend away from each other when a pressure is applied and they return back to a default position (closer to each other) when the pressure is released.
The conduit connector is adapted to be connected to the light module to provide electrical power to a light source in the light module. In particular, the one or more wire connectors of the conduit connector and the one or more wire connector receptacles of the light module are designed to operate as a plug-and-socket assembly. That is, the portion of the one or more wire connectors that extends out from underneath the housing of the conduit connector matingly engages the corresponding one or more wire connector receptacles of the light module to provide electrical power from the external power source/junction box to the light source in the light module. Specifically, the one or more wire connectors of the conduit connector enter the corresponding one or more wire connector receptacles of the light module through the top end of the one or more wire connector receptacles exposed by the opening of the locking clip. Even though the wire connectors enter the wire connector receptacles from a top surface of the light module, the substantially right angle alignment of the wire connectors with the housing of the conduit connector allows the conduit to approach the light module horizontally for coupling with the light module, rather than having to approach from vertically above the light module as in conventional light fixtures. That is, the connector system of the present disclosure allows the conduit to be horizontally oriented in a plenum space when the conduit connector is connected to light module at a top surface of the light module, thus, resulting in a low profile. This ability to couple a horizontally oriented conduit to the light module allows for installation of the light fixture in a plenum space that is shallow.
Further, the conduit connector is coupled to and locked in position with the light module by the locking clip. For example, to connect the conduit connector to the light module, a customer applies pressure (either using fingers or using the housing of the conduit connector) on the two arms of the locking clip to push them away from each other. Then, the customer inserts the conduit connector in between the arms of the locking clip. Further, the one or more wire connectors of the conduit connector is inserted into the corresponding one or more wire connector receptacles in the light module. In particular, the wire connectors are inserted into the wire connector receptacles from the top end of the wire connector receptacles that is exposed through the axially aligned openings of the locking clip and the top surface of the light module. Once the wire connectors in the conduit connector are inserted into the wire connector receptacles in the light module, the customer releases the pressure on the two arms of the locking clip causing the two arms spring back inward, i.e., towards each other. Alternatively, if the user does not push the arms of the locking clip apart and simply pushes the conduit connector into the locking clip, the arms of the locking clip are biased inward against the conduit connector. When the arms of the locking clip are biased inward, they clamp the housing of the conduit connector disposed in between the arms and lock the conduit connector in position. All of the above-mentioned operations to connect the conduit connector to the light module can be done by the customer using one hand. Accordingly, the locking clip facilitates a one-handed and tool-less quick connect and/or disconnect of the conduit connector with the light module.
Furthermore, the connector system is configurable to accommodate more than one wire connector by adapting the design of the housing of the conduit connector and the opening of the locking clip. For example, the connector system is configurable to accommodate two wire connectors, four wire connectors, six wire connectors, or more based on the application for which the connector system is used and the amount of electrical power needed for the respective application. In some embodiments, an odd number of wire connectors may also be used. Furthermore, the housing of the conduit connector is also configurable to accommodate conduits of different sizes, shapes, and material.
The technology of the present disclosure can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the technology to those having ordinary skill in the art. Furthermore, all “examples” or “example embodiments” given herein are intended to be non-limiting and among others supported by representations of the present technology.
A connector system for light fixtures will now be described in more detail in association with
Two Wire Connector System

In certain example embodiments, the conduit receiving portion 560 of the bottom housing 108 may include a substantially semi-cylindrical wall 511, a first side wall 510a extending upwards from a longitudinal edge 511a of the substantially semi-cylindrical wall 511 to a top edge 513 of the bottom housing 108, and a second side wall 510b extending upwards from an opposite longitudinal edge 511b of the substantially semi-cylindrical wall 511 to an opposite portion of the top edge 513. The first side wall 510a may be parallel to the second side wall 510b. Further, as illustrated in
In certain example embodiments, the wire connector portion 570 of the bottom housing 108 may include a front wall 512c that extends from a bottom edge 515 of the bottom housing 108 to a front portion of the top edge 513, and a back wall 512d that is opposite to the front wall 512c. Further, the wire connector portion 570 of the bottom housing 108 may include a first side wall 512b that extends from one side edge of the front wall 512c towards the first side wall 510b of the conduit receiving portion 510, and a second side wall 512a that extends from an opposite side edge of the front wall 512c towards the second side wall 510a of the conduit receiving portion 560. As illustrated in
In particular, the two-wire connector 110 may include a first wire connector 702a and a second wire connector 702b as illustrated in

Referring now to
In addition to the curved top surface 651, the conduit receiving portion 650 of the top housing 106 may include a relief rib 604 that is configured to bias against a contoured/ribbed surface of the conduit 102 to securely lock or retain the conduit 102 within the mechanical housing assembly 104 and prevent the conduit 102 from being pulled out once it is coupled to the mechanical housing assembly 104.
Further, as illustrated in
As illustrated in
As illustrated in
In particular, the conduit 102 houses and carries electrical lines from a power supply source to the mechanical housing assembly 104. The conduit 130 is typically flexible, for example metallic interlock conduit, with the metallic composition providing electrical conductivity for an electrical ground. That is, ground current, if present, may flow along the conduit 130 via the conduit's metal composition. Other embodiments may utilize other conduits or tubes for housing electrical lines. Such conduits may be rigid in some embodiments and flexible in other embodiments and may be either conductive or nonconductive. A conduit composed of electrically insulating material may carry a dedicated ground wire in addition to wires forming an electrical supply circuit, for example.
In certain example embodiments, the electrical wires that enter the mechanical housing assembly 104 via the conduit 102 may be routed to the two-wire connector 110 through the middle portion and the cavity 602 formed by the wire connector portion 670 of the top housing 106. In other words, the mechanical housing assembly 104 provides a concealed pathway for the electrical wires from the power supply source to the two-wire connectors 110. In particular, the electrical wires may enter the mechanical housing assembly 104 through the end of the conduit 102 that is overlappingly retained by the mechanical housing assembly 104. Further, the electrical wires may be routed into the cavity 602 formed above the two-wire connector 110, bent downwards towards the two-wire connector 110, and coupled to the two-wire connector 110.
Even though the present disclosure describes a specific shape and structure of the top housing and the bottom housing, one of ordinary skill in the art can understand and appreciate that in other example embodiments, the top housing and the bottom housing can have any other appropriate shape that allows the wire connectors to form a substantially right angle with the housing of the conduit connector without departing from a broader scope of the present disclosure. Further, even though the present disclosure describes the conduit connector as being configured to house a substantially cylindrical conduit, one of ordinary skill in the art can understand and appreciate that in other example embodiments, the mechanical housing assembly, i.e., the top housing and the bottom housing of the conduit connector may be configured to receive and retain a conduit having any other appropriate shape without departing from a broader scope of the present disclosure. For example, the conduit connector may be configured to house a square shaped conduit (square cross-section) with no ribbed/contoured surfaces.
Referring now to
In particular, the connector portion of the outer housing 291 may be raised compared to the heat sink portion 232 such that it can accommodate the two-wire connector receptacle 241 in a vertical or standing up position. Further, the heat sink portion 232 may be configured to dissipate heat generated by a light source (not shown) that is coupled to outer housing 291. In certain example embodiments, the light source may be coupled to the two-wire connector receptacle 241 using one or more electrical wires that are concealed by a wire cover member (not shown) that is coupled to and disposed underneath the outer housing 291. The wire cover member may also be configured to provide support the vertically oriented two-wire connector receptacle 241 in the connector portion 222 of the outer housing 291.
As illustrated in
In addition to the opening 302, the top surface 224 of the light module 204 may include a through aperture 306 that is disposed on one side of the opening 302 and a through slot 304 disposed on an opposite side of the opening 302. In particular, the through aperture 306 and the through slot 304 may be configured to facilitate the locking clip 220 to be coupled to the top surface 224 of the light module 204. The locking clip 220 may be described in greater detail below in association with
Referring now to
Further, the planar base portion 402 may include a through aperture 404 located adjacent the first lateral edge 450a. Furthermore, the planar base portion 402 may include an opening 406 that extends through the planar base portion 402 and disposed between the two longitudinal edges 450c and 450d. In particular, the opening 406 on the planar base portion 402 of the locking clip 220 may be configured to expose the top ends of one or more two-wire connector receptacles 241 and/or 241a when the locking clip 220 is coupled to the top surface 224 of the light module 204. For example, in one embodiment illustrated in
Even though the present disclosure describes a two wire connector system and a four-wire connector system, one of ordinary skill in the art can understand that in other embodiments, a connector system having fewer or more number of wire connectors may be within the broader scope of the present disclosure. For example, in some embodiments, the conduit connector of the connector system may be configured to house six wire connectors, and similarly, the locking clip may be configured to expose six wire connector receptacles in the light module 204.
Still referring to
In certain example embodiments, the arms 412a and 412b of the locking clip 220 may be flexible such that they push away from each other when pressure is applied on them, and they return back to their default position when the pressure is released. For example, a user can push the two arms away from each other by applying pressure on the upper portion of the two arms with two fingers. However, when the user releases the pressure by removing the two fingers from the upper portion of the two arms, the two arms return to their default state, i.e., they spring back towards each other.
In certain example embodiments, as illustrated in
Even though the present disclosure describes a specific mechanism for coupling the locking clip 220 to the light module 204, one of ordinary skill in the art can understand and appreciate that the locking clip 220 can be coupled to any other portion of the light module 204 using any other appropriate coupling mechanism without departing from a broader scope of the present disclosure. Further, even though the present disclosure describes a locking clip as having several portion, one of ordinary skill in the art can understand and appreciate that in other example embodiments, the locking clip can have fewer or more portions without departing from a broader scope of the present disclosure. For example, in some embodiments, the locking clip 220 may not include the tongue member 408. Alternatively, in other embodiments, the locking clip 220 may be replaced by any other device that satisfies the function of the locking clip as described herein, i.e., mate the conduit connector with the light fixture part, securely retain the conduit connector in position when it matingly engages the light module, and/or allow a one-handed and tool-less connect and disconnect of the conduit connector with the light module.
In particular, to connect the conduit connector 100 to the light module 204, first, a user may push the arms 412a and 412b of the locking clip 220 away from each other. Then, the user may position the mechanical housing assembly 104 of the conduit connector 100 in between the two arms 412a and 412b of the locking clip 220 such that the bottom portion 703 of the wire connector(s) 110 that projects out from the mechanical housing assembly 104 is above the opening 406 of the locking clip 220 that exposes the top end of the wire connector receptacles 241. Further, the user may push the mechanical housing assembly 104 to insert the bottom portion 703 of the wire connector(s) 110 that projects out from the mechanical housing assembly 104 into the wire connector receptacles 241 of the light module 204. In certain example embodiments, the light module 204 may receive electrical power when the bottom portion 703 of the wire connector(s) 110 is fully inserted into the wire connector receptacles 241. However, in other example embodiments, a partial insertion may be enough for the light module 204 to receive electrical power from the external power source via the conduit connector 100. Once, wire connector(s) 110 of the conduit connector 100 are is inserted into the wire connector receptacles 241 of the light module 204, the user may release a pressure on the arms (412a, 412b) of the locking clip 220 which causes the arms (412a, 412b) to spring back towards each other such that they engage the mechanical housing assembly 104 of the conduit connector 110 that is disposed in between the arms (412a, 412b). In particular, the bottom portion 414 of the two arms (412a, 412b) engages the flanges 520 on the bottom housing 108 of the conduit connector 110 to securely retain the connection between the conduit connector 110 and the light module part 242.
In certain example embodiments, the user may push the arms (412a, 412b) of the locking clip 220 away from each other by using the user's fingers. Alternatively, in other example embodiments, the user may push the arms (412a, 412b) of the locking clip 220 away from each other by pushing on the top portion 410 of the arms (412a, 412b) using the mechanical housing assembly 104 of the conduit connector 100. As the arms push away, the mechanical housing assembly 104 of the conduit connector 100 may slide downwards till the flanges 520 of the mechanical housing assembly 104 snap into or engage the bottom portion 414 of the arms (412a, 412b). Either ways, the locking clip 220 allow a single handed and tool-less quick connect and disconnect of the conduit connector 100 with the light module 204.
Even though the present disclosure describes the conduit connector as being connected to the light module using the locking clip, one of ordinary skill in the art can understand and appreciate that in other example embodiments, the locking clip may be optional. That is, in other example embodiments, the conduit connector may be connected to the light module without a locking clip or alternatively, using any other device that functions like the locking clip. In said embodiment without the locking clip, the bottom housing of the conduit connector may or may not include the flanges 520. Further, as described above, the mechanical housing assembly of the conduit connector and the locking clip can be configured to accommodate more than two wire connectors, for example, four wire connectors. The four wire connector system may be described in greater detail below in association with
Four Wire Connector System
Referring to
Further, the wire connector portion 1316 of the bottom housing 1008 may include two horizontally oriented flanges 1320 that extend out substantially perpendicularly from the side walls of the wire connector portion 1316. Furthermore, the bottom housing 1008 may include a middle portion having a sloped surface 1308 that inclines upward from the conduit receiving portion 1302 towards the wire connector portion 1316. The middle portion having the sloped surface 1308 may be configured to route electrical wires from the conduit 102 to each two-wire connector 110 of the pair of two-wire connectors.
Referring to
In addition to the conduit receiving portion 1402, the top housing 1006 may include a wire connector portion 1401 that has a raised top surface 1012. In particular, the raised top surface 1012 of the top housing's wire connector portion 1401 may define a cavity 1450 that is configured to route the electrical wires from the conduit 102 to each two-wire connector of the pair of two-wire connectors 110. The raised top surface 1012 may provide extra space for receiving and bending the wires down towards the two-wire connectors 110.
As illustrated in
The light module 204 of the four wire connector system may be substantially similar to that of the two wire connector system described above, except for the opening of the locking clip. Accordingly, for sake of brevity, only relevant differences between the locking clips of the four wire connector system and the two wire connector system may be described below. Referring now to
The coupling of the locking clip 1120 to the top surface 224 of the light module 204 may be substantially similar to that in the two wire connector system described above and therefore, will not repeated for sake of brevity. Similarly, the connection and disconnection of the conduit connector with the light module of the four wire connector system may be substantially similar to that of the two wire connector system, and therefore, will not be repeated for sake of brevity.
