One embodiment of the invention includes a lighting device packaging and delivery system for a partially or completely preassembled and pre-wired luminaire and pole. The packaging and methods allow the unit to be shipped and installed with very little or no assembly required. The unit, or multi-pack of units, may be packaged with all of the required components, such as the photo control and lamp, already installed.

## Background
FIELD OF THE INVENTION
The present invention relates to packaging, and particularly, relates to packaging and delivery of large lighting devices and equipment.
BACKGROUND OF THE INVENTION
Outdoor lighting devices, such as streetlights, are commonly used to aid automobile and pedestrian safety at night and in unfriendly weather conditions. A streetlight is typically a raised lamp near the edge of a street that is turned on or lighted at a certain time each night. Streetlights may also have light-sensitive photocells that turn them on and off automatically, for example, on at dusk or in bad weather and off at sunrise. Streetlights typically include, or attach to, a pole or other structure to raise them above the ground. Such poles can have lengths exceeding 20 feet. In many cases, the light or lights at the top of a streetlight pole are connected to an electricity source through electrical wiring that runs down through the pole.
Lighting devices often require a significant amount of assembly, installation, and setup after delivery. Assembling and electrically connecting components can be time-consuming and may require the assistance of an expert, technician, or electrician. The need for electrical expertise and assembly is even more common and burdensome for larger lighting devices, such as streetlights, which are usually shipped in a partially unassembled manner because of their size or shape. When the pole, lamps, and other components of a streetlight are shipped or delivered in unassembled form, a significant amount of time and effort may be required to properly assemble and electrically connect the various components. In some cases, this work must be done at the top of a pole high above ground level, requiring additional equipment such as ladders and high-reach trucks.
The components of large lighting devices such as streetlights are commonly ordered separately from one another. Past ordering methods have involved having a purchaser place individual purchase orders for each of a lamp, a control, a luminaire, a pole, and wiring. The separate ordering of the lighting device's components typically requires additional effort in order to coordinate shipment schedules such that the materials will arrive at the same time. Additionally, there is a risk that one or more of the components will not arrive at its scheduled delivery time, delaying the installation of the lighting device.
SUMMARY OF THE INVENTION
One embodiment of the present invention includes a package for a lighting device that includes an encasing structure that surrounds at least a portion of a luminaire of the lighting device. An aperture in the encasing structure is configured to allow a pole connected to the luminaire to extend from the encasing structure. Another embodiment of the present invention includes a method of packaging a lighting device that includes encasing the luminaire of the lighting device with an encasing structure of a package such that a pole of the lighting device extends through an aperture. A third embodiment of the present invention includes a method of selling a lighting device that includes offering for sale a lighting device, which includes a luminaire preassembled to a pole, under a single item code, accepting an order for the single item code for delivery to a delivery location, and shipping the lighting device to the delivery location.

DETAILED DESCRIPTION OF THE INVENTION
Introduction
One embodiment of the invention includes a lighting device packaging and delivery system for a partially or completely preassembled and pre-wired luminaire and pole. The packaging allows the unit to be shipped and installed with very little or no assembly required. The unit, or multi-pack/bundle of units, may arrive at the destination with all of the required components, such as the photocontrol and lamp, already installed. Upon arrival, the installer will remove the packaging protecting the luminaire and possibly some wrapping protecting a pole, orient the fixture in the proper direction if needed, and lower it into the prepared hole for the direct burial pole. The supply wiring is pulled through the proper openings in the pole base, the wiring is connected, and pole installation is completed. In some embodiments, the packaging is designed to interlock with other units of the same type to form a multi-pack or bundle. For example, the packaging may have one or more recesses to allow adjacent luminaires or poles of other lighting devices to be secured.

FIGS. 1 and 2 show a packaged lighting device 100. An encasing structure 101 having a first portion 102 and second portion 104 is used to package, ship, deliver, store, and/or display lighting device 106. The encasing structure 101 may have a rectangular outer shape, a square outer shape, or any other suitable shape, and may be composed of two separable portions 102, 104, as shown, or of any suitable number of components or pieces. As shown, in this embodiment, the two portions 102, 104 of the encasing structure 101 encase primarily the luminaire 108 of the lighting device 106, and allow the pole 110 to extend outward from the packaging. Note that the term “pole” is not limited to any particular shape or size. Any suitable extending structure may be used. In some cases, the lighting device 106 will be a streetlight with a pole 110 having a length greater than 5 feet, 8 feet, 10 feet, 12 feet, 15 feet, 20 feet, or more.
Also note that although this embodiment describes an encasing structure 101 having two portions 102, 104, in other embodiments, the encasing structure 101 may consist of only one portion or more than two portions of different or the same shapes, sizes, materials, and configurations. Different portions of a multi-portion package may be secured to one another, the luminaire, and/or other portions of the lighting device by connectors, through an interference fit, a surrounding structure or encasement, and/or any other suitable means. Alternatively, the portions may not be secured together or to other structure in some embodiments.
In the embodiment of FIGS. 1 and 2, the inside 112 of each of the portions 102, 104 of the encasing structure 101 is configured or shaped so that, once encased, the luminaire 108 of the lighting device 106 will be partially or completely surrounded by protective packaging materials. The invention is not limited to any particular size, shape, configuration, material, type, or style of packaging or protection. The inside 112 of each of the portions 102, 104 of the encasing structure 101 may be made of any suitable material and shaped to generally match or conform to the outer shape of the luminaire 108.
The first portion 102 and the second portion 104 of the encasing structure 101 of the package are also each configured to form respective semi-circles 114a, 114b on one end. The respective semi-circles 114a, 114b come together to form a circular aperture 116 when the package is installed around the luminaire 108 of the lighting device 106, as shown in FIG. 2. The pole 110 extends through aperture 116. In some embodiments, the aperture will have a shape and size similar to the shape and size of a cross section of the pole. In other embodiments, the aperture will have a different shape and size. For example, the aperture may be larger than the cross section of the pole of a lighting device.
The portions 102, 104 of the encasing structure 101 may only partially surround the luminaire 108, and may surround a portion or all of the pole 110. As explained in greater detail below, the portions 102, 104 may also be configured such that the package can be secured, connected, or attached to another package or lighting device component such as a pole. The encasing structure configuration, whether including one or more portions, may include one or more package recesses 118, projections, and/or pole recesses 120a, 120b, 120c, 120d, that work alone or in combination with other components to secure, attach, connect, or otherwise hold packaging or a lighting device.
One embodiment of the present invention is a method of packaging a lighting device comprising encasing a luminaire of the lighting device with portions of an encasing structure of a package, wherein a pole of the lighting device extends through an aperture.

Advantages
Some embodiments of the of the present invention may save a lighting device customer or installer a large amount of time and expense by avoiding or reducing the need to assemble the components of a luminaire required to make the unit operable (i.e., the lamp, pole, photocontrol, etc.). In some embodiments, the luminaire may be shipped and delivered in a preassembled form, such that the pole, lamp, photocontrol, and other components are preassembled, connected, and/or wired together. Accordingly, in many embodiments, a technician or electrician will not be required to wire the lamp, pole, and other components. Moreover, in many embodiments, equipment such as a ladder or bucket truck will not be required to install the luminaire at the top of a pole, since the electrical connections between the lamp, pole, and other components may be done prior to shipment and installation of the luminaire.
Another advantage to some embodiments, is that the same lighting device package may be used to ship luminaires individually and luminaires preassembled with other lighting device components such as a pole. In these embodiments, the shape of the packaging encases primarily the luminaire but allows for a pole to extend outwardly. If no pole is attached, the package simply encases the luminaire.
