The present invention relates generally to the art of landscape lighting systems, and more particularly, to a junction hub for a landscape lighting system that enables the connection of devices of the landscape lighting system.
Outdoor landscape lighting systems are commonly used in both commercial and residential settings for the illumination of structures, walkways, trees, shrubbery, etc. In an outdoor landscape lighting system, users may find it difficult and time consuming to install multiple lighting fixtures. For example, the user may spend considerable time and employ various tools to connect each lighting fixture in parallel with a power source of the landscape lighting system. Moreover, if a problem arises in the landscape lighting system, the user may have difficulty troubleshooting where the problem exists. Even further, if a lighting fixture has to be repaired or removed or if an additional lighting fixture is added to the landscape lighting system, the user may find it difficult and time consuming to do so.
Example embodiments of the present invention recognize and address considerations of prior art constructions and methods.
One aspect of the present invention provides an outdoor landscape lighting junction hub. The junction hub comprises a fixture body having a top portion and a bottom portion removably connectable together to define an interior. A connector device for operably coupling a mounting structure to the fixture body is also provided. A terminal block is disposed in the interior of the fixture body for facilitating the connection of a power source to at least one lighting fixture. For example, the terminal block may be connected to the top portion of the fixture body.
In some exemplary embodiments, the bottom portion of the fixture body defines at least one opening for receiving wires of the power source or the at least one lighting fixture. A respective cap may be situated in the at least one opening to seal the opening when not in use.
In some exemplary embodiments, the connector device may be in the form of a depending boss defining exterior threads thereon integrally extending from the bottom portion of the fixture body. The depending boss may be hollow to allow passage of wires therethrough.
In some exemplary embodiments, the terminal block may comprise a first polarity terminal portion and a separate second polarity terminal portion.

According to other embodiments, the top portion and the bottom portion may be threadably connected.
Preferably, the terminal block may comprise a plurality of ports and a respective locking mechanism corresponds to each of the ports to releasably retain a respective wire therein.
Another aspect of the present invention provides an outdoor landscape lighting system comprising a power source and at least one lighting fixture. At least one junction hub is also provided having a fixture body comprising a top portion and a bottom portion defining an interior. A mounting structure is coupled to the fixture body. A terminal block is disposed in the interior of the fixture body for facilitating the connection of the power source to the least one lighting fixture.
Those skilled in the art will appreciate the scope of the present invention and realize additional aspects thereof after reading the following detailed description of example embodiments in association with the accompanying drawing figures.
A full and enabling disclosure of the present invention, including the best mode thereof directed to one of ordinary skill in the art, is set forth in the specification, which makes reference to the appended drawings, in which:
Reference will now be made in detail to presently preferred embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that modifications and variations can be made in the present invention without departing from the scope or spirit thereof. For instance, features illustrated or described as part of one embodiment may be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations. Like reference numerals refer to like elements throughout. Furthermore, as used herein, the term “or” is to be interpreted as a logical operator that results in true whenever one or more of its operands are true. As used herein, operable coupling should be understood to relate to direct or indirect connection that, in either case, enables functional interconnection of components that are operably coupled to each other.
Users may prefer a landscape lighting system that is easy and quick to setup and install, and if a problem arises in the landscape lighting system, that is easy to troubleshoot and repair. Some example embodiments described herein provide a landscape lighting system having a junction hub. The junction hub provides a junction for the easy connection of a power source and one or more lighting fixtures of the landscape lighting system. Further, the junction hub enables the efficient replacement or addition of lighting fixtures to the landscape lighting system. Moreover, some embodiments may provide a convenient location for testing or troubleshooting problems arising in the landscape lighting system.
The lighting fixtures 30 may be placed where desired throughout an outdoor landscape and connected to the power source 20 via the junction hub 40. Accordingly, when using a junction hub 40 as part of the landscape lighting system 10, the installation time associated with installing the components of the landscape lighting system 10 may be reduced.
The power source 20 of the landscape lighting system 10 may comprise a transformer. The transformer may plug into a standard AC outlet, such as a 120 VAC outlet typically used in North America. Moreover, the transformer may have AC outputs between 8V-15V. The transformer may also have control circuitry and be used as part of a control panel for collectively controlling the lighting fixtures 30 throughout the outdoor landscape. For example, the control panel can include a timer that turns all of the lights on or off at specified intervals, or a control for brightening or dimming the lighting fixtures 30 in the landscape lighting system 10. One skilled in the art will appreciate that other means for powering the lighting fixtures 30 are within the scope of the invention. For example, the power source 20 may be solar or battery powered or the like.
As shown, at least one lighting fixture 30 may be connected to the junction hub 40 by wiring.

As shown in
The bottom portion 104 of the fixture body 100, as shown in
The user may pass respective wires of the power source 20 or the lighting fixtures 30 through an opening 106 in order to connect the power source 20 and the lighting fixtures 30 to the terminal block 200 (and thus each other). Each opening 106 may preferably include a removable cap 107. The cap may be removed from the opening 106 when in use and the opening 106 may stay effectively sealed by the cap when not in use. In even further example embodiments, the cap in each opening 106 may be in the form of a flexible grommet having an expandable aperture for passage of wires. Thus, although the cap may or may not be removable, it need not be removed for use. Instead, wiring may enter the junction hub 40 through the expandable aperture. In this case, the grommet will provide an effective barrier to water penetration even when the corresponding hole 106 is in use. The expandable aperture may be formed by a flexible webbing having a weakened portion such as slit that is broken when a wire is initially pushed through it.
The junction hub 40 may also include a connector device 110. The connector device 110 may integrally extend from an exterior surface of the bottom portion 104 of the fixture body 100. In accordance with some example embodiments, a first end of the connector device 110 may be disposed inside the junction hub 40, and the second end of the connector device 110 may be disposed outside of the junction hub 40. In some cases, the connector device 110 may be in the form of an exteriorly threaded boss for operably coupling a mounting structure 300 (see
Referring again to
The partition wall 210 may define at least one gap 214 (or other suitable opening) allowing passage of a respective fastener (e.g., a bolt) that connects terminal portions 202 and 204. Tightening of the fastener(s) thus causes firm engagement of terminal portions 202 and 204 with wall 210 to retain terminal portions 202 and 204 in position. The example embodiment illustrated in
As one skilled in the art will appreciate, terminal block 200 enables the electrical connection of several devices located in a landscape lighting system 10 such as power source 20 and one or more of the lighting fixtures 30. Moreover, the terminal block 200 provides a convenient place for troubleshooting problems associated with the landscape lighting system 10. Even further, because the terminal block 200 may serve as a point for connection of the lighting fixtures 30 to the power source 20, voltage received from the power source 20 may be substantially equalized among each of the lighting fixtures 30 connected to the terminal block 200. Additionally, because the terminal block 200 is located in the fixture body 100, the terminal block 200 is protected from weather while the connections made at the terminal block 200 are secure and dry for improved long-term reliability.
Each terminal portion 202 and 204 may have an insulative outer shell defining a plurality of ports 205 and a corresponding clamp 206 (see
In order to connect the power source 20 and the lighting fixtures 30 to the terminal block 200 (i.e., the first and second terminal portions 202 and 204), the wires of the power source 20 and lighting fixture 30 are inserted into respective ports of the first and second terminal portions 202 and 204. For example, the wires of the power source 20 may be inserted by a user into the first set of ports indicated at 208. Accordingly, the positive wire of the power source 20 may be inserted into one of the ports 205 of the first terminal portion 202 (i.e., positive terminal portion), and the negative wire of the power source 20 may be inserted into a corresponding one of the ports 205 of the second terminal portion 204 (i.e., ground terminal portion), such as the first set of ports 208. It should be understood that each of the lighting fixtures 30 may be coupled to the first and second terminal portions 202 and 204 in a similar manner as the power source 20. Accordingly, the wires of a lighting fixture 30 may be inserted by a user into any available set of opposite-polarity ports 205.
As noted above, each port 205 may have a corresponding clamp 206 (see
In order to provide power to the lighting fixtures 30 of the landscape lighting system 10, the wires of the power source 20 may be passed through one of the openings 106 of the fixture body 100 to connect the wire ends to one of the sets of ports 205 of the terminal block 200. Moreover, the wires of the lighting fixture 30 may also be passed through one of the openings 106 to connect to another open or available set of ports 205. Once the power source 20 and the lighting fixture 30 are all connected to the terminal block 200, power is provided to the lighting fixtures 30. One or more of these wires may alternatively be passed through a central bore of connector device 110.
In this embodiment, each terminal portion 202 and 204 may include eight ports 205. Accordingly, junction hub 40 may enable the connection of up to eight devices (e.g., one power source 20 and up to seven lighting fixtures 30). In other cases, however, each terminal portion 202 and 204 may include more or less than eight ports 205. Thus, the junction hub 40 may enable the connection of more or less than eight devices.
Lighting fixture 530 can be further explained with reference to
Certain additional details regarding fixture body 600 can be most easily explained with reference to
Terminal portions 702 and 704 are diametrically opposed on opposite sides of a central opening 570 defined in first portion 602 of fixture body 600. As will be explained more fully below, central opening 570 is formed by a depending boss that defines internal threads. Central opening 570 thus allows attachment of the support post 562 of lighting fixture 530, which defines exterior threads on its lower, proximal end. In other words, the support post is attached to fixture body 600 of junction hub 540 in the same manner that it would otherwise be attached directly to stake 300. Wiring for the lighting fixture 530 enters fixture body 600 through central opening 570.
The exterior of fixture body 600 may advantageously be formed of an aesthetically pleasing material, such as brass, and has a relatively small height, to complement the appearance of the lighting fixture 530. For example, the disc-shaped configuration of fixture body 600 may resemble a brass stake-cover as are sometimes used to conceal the plastic material from which outdoor lighting stakes are frequently made. Regardless of aesthetic concerns, the exterior of fixture body 600 is preferably sufficiently durable that it will not be damaged by common landscaping equipment such as string trimmers. In addition, it will often be desirable to attach the stake to junction hub 540 and hammer the combination into the ground prior to attaching support post 562. This avoids wires twisting inside the fixture body 600.
Junction hub 540 permits all electrical connections for lighting fixture 530 to be made above ground. In some embodiments, junction hub 540 may be provided separately from the lighting fixture (e.g., as a retrofit) to improve and simplify the lighting connections. In other cases, junction hub 540 may be provided as part of the lighting fixture 530 when sold. In the latter case, lighting fixture 530 need not have a wiring “tail” since the internal wiring only needs to be long enough to reach terminal portions 702 and 704. At the time of installation, an installer then brings field wiring into the junction hub 540 for connection to the fixture wiring using terminal portions 702 and 704.
First portion 602 and second portion 604 may be slidably connected together to close fixture body 600, or they may be connected together via threads. Referring now to
