TECHNICAL FIELD
This document relates to outdoor lighting and, more particularly, to outdoor lighting assemblies.
BACKGROUND
Proper outdoor lighting can provide numerous benefits. For example, outdoor lighting can often improve safety by illuminating potential hazards so that people can prepare for and deal with them. Similarly, outdoor lighting can often enhance security in that people are less likely to engage in illicit conduct if they think that they might be seen. Additionally, and perhaps most importantly, outdoor lighting can create a pleasing, decorative effect by highlighting the character of structures and landscapes.
Outdoor lighting assemblies come in a variety of shapes and sizes. Examples include upright lamps, floodlights, tier lights, well lights, and surface-mount lights. Moreover, outdoor lighting assemblies can be powered via high-voltage energy sources, low-power energy sources, or solar power. Outdoor lighting assemblies can be used to illuminate home architecture, decks, walkways, driveways, gardens, ponds, swimming pools, and other structures or landscapes.
In some environments, outdoor lighting assemblies can be damaged by ordinary outdoor activities. For example, people sometimes bump outdoor lighting assemblies with their lawnmowers, thereby bending or breaking the outdoor lighting assemblies. Likewise, children may damage outdoor lighting assemblies while playing outdoors. Other outdoor activities that can damage outdoor lighting assemblies involve garden hoses, ladders, landscapers, and pets. Damaging outdoor lighting assemblies becomes an even bigger issue given the fact that many outdoor lighting assemblies are designed to be relatively inconspicuous in the daylight.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
The following detailed description of illustrative embodiments should be read with reference to the figures, in which like elements in different figures are numbered identically. The figures depict illustrative embodiments and are not intended to limit the scope of the invention. Rather, the present invention is defined solely by the claims.
FIG. 1 shows an embodiment of an outdoor lighting assembly 5. The outdoor lighting assembly 5 of FIG. 1 includes a stake 7, a tube 8, a base receptacle 10, a connector 15, and a lighting unit 20. With the stake 7, the tube 8, and the base receptacle 10 coupled together, a user can prepare the outdoor lighting assembly 5 for operation by burying it partially in the ground. In operation, the stake 7, the tube 8, and part of the base receptacle 10 can be buried underground, while the remainder of the base receptacle 10, the connector 15, and the lighting unit 20 can extend vertically from the ground. The tube 8 can be made of, e.g., PVC, and can extend far enough underground to ensure that electrical wires are buried at an adequate depth.
The lighting unit 20 of FIG. 1 is an upright lamp. It includes a pole 25, a shade 30, wires 35, a light socket, and a light bulb. In embodiments in which the lighting unit 20 is an upright lamp, the lighting unit 20 may take various forms and may come in various styles. For example, the length of the pole 25 may be varied to adjust the diameter of illumination, to create a desired appearance of the lighting unit 20, or for any other reason. The diameter of the pole 25 may be varied. FIGS. 2A-2D show various illustrative embodiments of lighting units that can be used in some outdoor lighting assembly embodiments.
In the embodiment of FIG. 1, the lighting unit 20 and the connector 15 can be coupled to the base receptacle 10. The pole 25 of the lighting unit 20 can be inserted into a bore in the connector 15 to couple the lighting unit 20 and the connector 15 together. The connector 15 can also be coupled to the base receptacle 10. Connectors can allow a common base receptacle to interface with many different lighting units having poles of differing diameters. As such, a user can change lighting units without having to dig up the base receptacle.
FIGS. 3A-3D show a closer view of the base receptacle 10 of FIG. 1. The base receptacle 10 includes an insert 55, a locking device 60, and a multi-portioned cylinder 50. In many instances, the base receptacle 10 can make the outdoor lighting assembly less susceptible to damage caused by ordinary outdoor activities. For example, if the outdoor lighting assembly is bumped by a lawnmower, the base receptacle 10 can allow the outdoor lighting assembly to flex temporarily before returning to its original position rather than breaking. The multi-portioned cylinder 50 shown in FIGS. 3A-3D has three portions: a lower cylinder portion 65, a neck cylinder portion 70, and an upper cylinder portion 75. The three cylinder portions 65, 70, 75 may be integrally formed of the same material, such as an elastomer (e.g., rubber) or other flexible material. The three cylinder portions 65, 70, 75 shown in FIGS. 3A-3D are coaxial.
The multi-portioned cylinder 50 of the base receptacle 10 may be configured in a variety of ways. In some embodiments, the perimeter of the lower cylinder portion 65 (i.e., the circumference for lower portions having circular cross-sections) may be greater than the perimeters of either the neck cylinder portion 70 or the upper cylinder portion 75. In such embodiments, the lower cylinder portion 65 can be sized to interface with a tube (e.g., tube 8 of FIG. 1, tube 180 of FIG. 6). In some embodiments, the perimeter of the lower cylinder portion 65 can be between approximately 4 inches (10.16 centimeters) and 30 inches (76.2 centimeters). In some embodiments, the perimeter of the lower cylinder portion 65 can be between approximately 5 inches (12.7 centimeters) and 12 inches (30.48 centimeters). In some embodiments, the perimeter of the lower cylinder portion 65 is approximately 5.65 inches (14.351 centimeters). In some embodiments, the perimeter of the lower cylinder portion 65 is approximately 8.5 inches (21.59 centimeters). In some embodiments, the perimeter of the lower cylinder portion 65 is approximately 11.78 inches (29.921 centimeters).
In embodiments of the base receptacle 10 that include an upper cylinder portion 75, the upper cylinder portion 75 can be configured in a variety of ways. In some embodiments, the perimeter of the upper cylinder portion 75 can be between approximately 2.25 inches (5.715 centimeters) and 28 inches (71.12 centimeters). In some embodiments, the perimeter of the upper cylinder portion 75 can be between approximately 5.25 inches (13.335 centimeters) and 7.25 inches (18.415 centimeters). In some embodiments, the perimeter of the upper cylinder portion 75 is approximately 5.65 inches (14.351 centimeters).
The neck cylinder portion 70 of the base receptacle 10 can be configured in a variety of ways. In some embodiments, the uppermost and lowermost perimeters of the neck cylinder portion 70 are large relative to the perimeter at the narrowest cross-section of the neck cylinder portion 70. In some embodiments, the lowermost perimeter of the neck cylinder portion 70 may be approximately equal to the perimeter of the lower cylinder portion 65. Embodiments of the neck cylinder portion 70 can have lowermost perimeters within the same ranges as those discussed in connection with the lower cylinder portion 65. In some embodiments, the lowermost perimeter of the neck cylinder portion 70 may be slightly smaller than the perimeter of the lower cylinder portion 65. In some embodiments, the lowermost perimeter of the lower cylinder portion 65 is approximately 7.5 inches (19.05 centimeters). In some embodiments, the lowermost perimeter of the neck cylinder portion 70 differs from the perimeter of the lower cylinder portion 65. In some embodiments, the uppermost perimeter of the neck cylinder portion 70 may be approximately equal to the perimeter of the upper cylinder portion 75. Embodiments of the neck cylinder portion 70 can have uppermost perimeters within the same ranges as those discussed in connection with the upper cylinder portion 75. In some embodiments, the uppermost perimeter of the neck cylinder portion 70 differs from the perimeter of the upper cylinder portion 75.
As is shown most clearly in FIGS. 3B & 3D, the perimeter of the neck cylinder portion 70 may vary along its profile. In some embodiments, the smallest perimeter of the neck cylinder portion 70 can be between approximately 1.75 inches (4.445 centimeters) and 21.75 inches (55.245 centimeters). In some embodiments, the smallest perimeter of the neck cylinder portion 70 can be between approximately 2.5 inches (63.5 centimeters) and 6.25 inches (15.875 centimeters). In some embodiments, the smallest perimeter of the neck cylinder portion 70 is approximately 4.375 inches (11.11 centimeters). In some embodiments, the smallest perimeter of the neck cylinder portion 70 is closer to the lowermost perimeter than to the uppermost perimeter. In some embodiments, the ratio of the distance between the smallest perimeter and the uppermost perimeter to the distance between the smallest perimeter and the lowermost perimeter can be approximately between 1.25:1 and 4:1. In some embodiments, such ratio can be approximately between 2:1 and 2.5:1 (e.g., 2.25:1). In some embodiments, the smallest perimeter of the neck cylinder portion 70 is closer to the uppermost perimeter than to the lowermost perimeter. In some embodiments, the distance between the smallest perimeter and the uppermost perimeter is approximately equal to the distance between the smallest perimeter and the lowermost perimeter. In some embodiments involving a large moment arm (e.g., the base receptacle supports a relatively heavy component connected to the upper end of a relatively heavy pole), the lower half of the neck cylinder portion 70 can be more robust (e.g., can include more material) than the upper half. In some embodiments involving a small moment arm, the upper cylinder portion 75 and the lower cylinder portion can be approximately equally robust.
Base receptacles of outdoor lighting assemblies can come in a variety of shapes and sizes. For example, the lower portion of the base receptacle may have a polygonal, rather than circular, cross-section. The lower portion's cross section may be, for example, pentagonal or hexagonal. The neck portion and/or upper portion may have a cross section similar to the lower portion (e.g., all three cross-sections are circular, polygonal or other suitable cross section). In some embodiments, the three portions have different types of cross sections (e.g., the lower portion has a circular cross section, the neck portion has a hexagonal cross-section, and the upper portion has a pentagonal cross section). In some embodiments, only two of the three portions have the same type of cross section (e.g., the upper and lower portions are circular while the neck portion is polygonal). The base receptacle may include only a lower portion and a neck portion. The portions of the base receptacle may be separated by distinct changes in cross-section. The cross section of the base receptacle may transition seamlessly from one portion to the next. In some embodiments, the perimeter of the lower portion is approximately equal to that of the upper portion.
Base receptacles can be coupled to a variety of components in a variety of ways. The upper end of a base receptacle can be coupled to, e.g., a connector (such as connector 15 of FIG. 1 or a connector that enables a female interface to mate with a female interface), the base of a lighting unit (such as pole 25 of FIG. 1), standard electrical fittings, or other suitable components. The lower end of a base receptacle can be coupled to, e.g., a relatively short stake (see FIGS. 7A-7C) for situations in which electrical wires are to be buried relatively shallowly, a relatively long tube (e.g., tube 8 of FIG. 1) for situations in which electrical wires are to be buried relatively deeply, an electrical box (either directly or via a connector that allows an electrical box having a female interface to be coupled to a base receptacle having a female interface), or other suitable components. In some embodiments, such as the embodiment of FIGS. 3A-3D, the base receptacle can have a female interface at its lower end and a female interface at its upper end. In such embodiments, the components that correspond to both the lower and upper ends of the base receptacle can have male interfaces. In some embodiments, the base receptacle can have male interfaces at both its upper and lower ends. In such embodiments, the components that correspond to both the lower and upper ends of the base receptacle can have female interfaces. In some embodiments, the interface at the upper end of the base receptacle differs from the interface at the lower end of the base receptacle (e.g., the upper end has a male interface and the lower end has a female interface, or vice versa). In some embodiments, the interface of the base receptacle and the interface of the corresponding component can have cooperating threads. In such embodiments, the base receptacle and the corresponding component can be screwed together. In some embodiments, the interface of the base receptacle and the interface of the corresponding component can be configured to be coupled together by press fitting. Many additional methods for coupling base receptacles to corresponding components are possible.
As discussed above, the base receptacle 10 of FIGS. 3A-3D has a female interface at its upper end. The base receptacle 10 of FIGS. 3A-3D includes an insert 55. The insert 55 may be threaded and may be capable of receiving a component having cooperating threads. In some embodiments, the insert can be proximate the lower cylinder portion 65. The insert 55 may be made of any suitable metal, polymer, or other suitable material. In some embodiments, the insert 55 is a 1⁄2 inch (1.27 centimeter) NTP brass insert. An axial bore extends through the insert 55 of FIGS. 3A-3D. The inner and outer diameters of the insert 55 may be varied according to the configuration of the multi-portioned cylinder 50, the configuration of the corresponding component, or for any suitable reason.
Some embodiments of the base receptacle 10 include a locking device 60 to secure a corresponding component into the base receptacle 10. In the embodiment of FIGS. 3A-3D, the locking device 60 includes an Allen screw that extends through a radial bore in the multi-portioned cylinder 50 and through a radial bore in the insert 55. The locking device 60 may be translated radially with respect to the multi-portioned cylinder 50 and the insert 55 between a secure position in which the locking device 60 contacts the corresponding component and a free position in which the locking device 60 does not contact the corresponding component. In some embodiments, the locking device 60 may be translated radially by, e.g., screwing an Allen screw into and out of the radial bores with an Allen wrench. In some embodiments, an ordinary screw may perform the function of the locking device 60. Many other locking devices are possible. For example, in base receptacles having one or more male interfaces, the locking device can be incorporated into the corresponding component. In some embodiments, the locking device can be an adhesive that couples a corresponding component and a base receptacle together.
An axial bore 80 extends through the multi-portioned cylinder 50 of FIGS. 3A-3D. The axial bore 80 may include a lower bore portion 85, a middle bore portion 90, and an upper bore portion 95. The lower bore portion 85, as is shown most clearly in FIG. 3C, may be housed entirely within the lower cylinder portion 65. The diameter of the lower bore portion 85 may be greater than the diameters of either the middle bore portion 90 or the upper bore portion 95. The middle bore portion 90 may be housed within all of the cylinder portions 65, 70, 75 and may extend through the entire neck cylinder portion 70. A lower ridge 100 may exist at the interface of the lower bore portion 85 and the middle bore portion 90. The lower bore portion 85 may be configured to receive a tube (such as tube 8 of FIG. 1). The tube may be inserted into the lower bore portion 85 and may be prevented from being inserted any further by the lower ridge 100. The diameter of the upper bore portion 95 may be greater than that of the middle bore portion 90. The upper bore portion 95 may be housed entirely within the upper cylinder portion 75. An upper ridge may exist at the interface of the upper bore portion 95 and the middle bore portion 90. The upper bore portion 95 may be configured to receive a cylindrical member. The cylindrical member may be inserted into the upper bore portion 95 and may be prevented from being inserted any further by the upper ridge. In the embodiment shown in FIGS. 3A-3D, the insert 55 may be inserted into the upper bore portion 95 and may be prevented from being inserted any further by the upper ridge. In some embodiments, the upper bore portion 95 may include threads. In such embodiments, the insert 55 may be unnecessary for interfacing with components having threads.
Referring back to FIG. 1, the outdoor lighting assembly 5 includes a connector 15. The connector 15 of FIG. 1 and a second connector 17 are shown in FIGS. 4A-4E. The connectors 15, 17 may each have a conical portion 110, a threaded portion 115, and two Allen screws 120. The threaded portion 115 may be a standard configuration so that the connectors 15, 17 may fit into a standard-sized receptacle (e.g., the insert 55 of FIGS. 3A-3D). An exterior ridge 125 may exist at the interface of the conical portion 110 and the threaded portion 115. When the threaded portion 115 is screwed into a receptacle, the exterior ridge 125 may contact the receptacle, thereby preventing the threaded portion 115 from being screwed into the receptacle any further. The conical portion 110 and the threaded portion 115 may be coaxial. As shown, the upper exterior diameter of connector 15 may be greater than that of connector 17. The Allen screws 120 may extend through radial bores and may be translated radially with respect to the conical portion 110 between a secure position in which the Allen screws 120 are configured to contact a member housed within the connector 15 and a free position in which the Allen screws 120 are not configured to contact a member housed within the connector 15. The Allen screws 120 may be translated radially by, for example, screwing them into and out of the radial bores with an Allen wrench. In some embodiments, ordinary screws may perform the function of the Allen screws 120.
An axial bore 130 may extend through each connector 15, 17. The axial bore 130 may include a lower bore portion 135 and an upper bore portion 140. The lower bore portion 135 may extend entirely through the threaded portion 115. The upper bore portion 140 may be housed entirely within the conical portion 110. The diameter of the upper bore portion 140 may be greater than the diameter of the lower bore portion 135. The diameter of the upper bore portion 140 of connector 15 may be greater than the diameter of the upper bore portion 140 of connector 17. An interior ridge 145 may exist at the interface of the upper bore portion 140 and the lower bore portion 135. When a cylindrical member (e.g., pole 25 of FIG. 1) is inserted into the upper bore portion 140, the cylindrical member may contact the interior ridge 145, thereby preventing further insertion of the cylindrical member into the connector 15, 17. Connectors can be configured to interface with cylindrical members having a variety of diameters.
To assemble the outdoor lighting assembly 5 of FIG. 1, an operator may connect the lighting unit 20 to the connector 15 and connect the connector 15 to the base receptacle 10. FIGS. 5A-5F show several stages of the assembly process. In some instances, the stake, the tube, and the base receptacle 10 are positioned in the ground before the lighting unit 20 and connector 15 are connected to the base receptacle 10. FIG. 6 shows a tube 180 similar to that of FIG. 1 that can be used to ensure that electrical wires are buried to a sufficient depth. The tube 180 can be cut to the desired depth. The tube 180 of FIG. 6 can be used with a stake similar to that of FIG. 1. FIGS. 7A-7C show a stake 150 that can be used when burying electrical wires to a specific depth is less important. Electrical wires can be fed through an aperture 175, and a base receptacle can be coupled to the stake 150.
Referring again to FIGS. 5A-5F, an operator may connect the lighting unit 20 to the connector 15. To do so, the operator may insert the wires 35 through the axial bore 130 in the connector 15. The operator may insert the pole 25 into the upper bore portion of the connector 15. The outdoor lighting assembly may be configured such that the outer diameter of the pole 25 is substantially equal to the inner diameter of the upper bore portion, thereby providing for a snug fit. Poles with smaller outer diameters may be used in connection with other connectors (e.g., connector 17 of FIGS. 4A-4E). The Allen screws 120 of the connector 15 may be translated radially toward the center of the multi-portioned axial bore 130. The Allen screws 120 may press against the pole 25, thereby creating or increasing frictional force that prevents the pole 25 from being removed from the upper bore portion.
In instances in which the stake, the tube, and the base receptacle 10 are buried first, the lighting unit 20 and connector 15 can be connected to the base receptacle 10 after the appropriate electrical connections have been made. To connect the connector 15 to the base receptacle 10, the operator may insert the wires 35 through the axial bore 80 of the base receptacle 10. The operator may screw the threaded portion 115 of the connector 15 into the insert of the base receptacle 10. The exterior ridge 125 of the connector 15 may contact the upper surface of the base receptacle, thereby preventing the connector 15 from screwing further into the base receptacle 10. The Allen screw 60 of the base receptacle 10 may be translated radially to contact the threaded portion 115 of the connector 15 and secure the connector 15 in position. The order of assembly of the outdoor lighting assembly disclosed in the preceding paragraphs is illustrative. The outdoor lighting assembly may be assembled in any suitable order.
The base receptacle 10 may be made of flexible material to prevent the outdoor lighting assembly 5 from being broken by the exertion of horizontal forces on the pole 25. For example, if a man was mowing his lawn and bumped his lawnmower into the pole 25, the neck cylinder portion 70 may allow some deflection of the pole 25, thereby absorbing some of the force exerted on the pole 25. In such a situation, a lighting assembly that did not include a flexible base receptacle may have been broken due to the impact of the lawnmower. In any of the embodiments disclosed in this document, an electrical socket may be provided accompanying the base receptacle 10. The electrical socket may make it easier to assemble and dissemble the lighting unit 20 and/or connector 15 from the base receptacle 15, while leaving the base receptacle 10 in the ground.
FIGS. 8A-8D show outdoor lighting assemblies 805, 810, 815, 820 according to some embodiments of the present invention. The outdoor lighting assembly 805 of FIG. 8A includes a base receptacle 825 (with a lower male interface and an upper female interface) that is to be coupled to a flood/spot light 830 and an electrical box 835. The outdoor lighting assembly 810 of FIG. 8B includes a base receptacle 840 that is to be coupled to a pathway garden fixture light 845 and a stake 850 (similar to that of FIGS. 7A-7C). Note that in FIG. 8B, the pole of the light 845 is to be coupled directly to the base receptacle 840, without the need for a connector. The outdoor lighting assembly 815 of FIG. 8C includes a base receptacle 855 that is to be coupled to a floodlight light 860 and a tube 865, which is to be coupled to a stake 870 (similar to that of FIG. 1). The outdoor lighting assembly 820 of FIG. 8D includes a base receptacle 875 that is to be coupled to a flood/spot light 880 and a tube 885, which is to be coupled to a stake 890 (similar to that of FIG. 1).
Base receptacles similar to those disclosed above may be used in outdoor members other than outdoor lighting assemblies. For example, base receptacles made of flexible material may be used in connection with flagpoles, mailboxes, street signs, or other members that may extend from the base receptacle. In such embodiments, the base receptacle made of flexible material may prevent the member from breaking when subjected to a force by absorbing a portion of the force.
Thus, illustrative embodiments of outdoor lighting assemblies are disclosed. One skilled in the art will appreciate that outdoor lighting assemblies can be practiced with embodiments other than those disclosed. The disclosed embodiments are presented for purposes of illustration and not limitation.
