## Background
TECHNICAL FIELD
The present disclosure relates generally to a globe clamp for an elevated lighting fixture. Specifically, the present disclosure relates to a globe clamp with integrated level mounting pads.
BACKGROUND
Elevated lighting fixtures for airfield applications are required by the Federal Aviation Administration (FAA) to have 4 degrees of adjustability in all directions after the lighting fixture is installed, which allows the lighting fixture to be leveled. This allows the light emitted from the lighting fixtures to be aligned in the correct direction. The underground support for these lighting fixtures may not be perfectly leveled or may shift overtime. Thus, having an adjustment range allows the lighting fixture to be adjusted into a position which compensates for the misalignment of the support. In certain example embodiments, the light fixture comprises one or more segments which couple together and ultimately couple to the underground support. The adjustment means may be implemented at one or more of the junctions of these segments. For example, a plurality of set screws may be used to couple a housing or support to a coupler, in which the lighting device is coupled to the other end of the housing. The configuration of the set screws may provide adjustability between the housing and the coupler, allowing the lighting device to leveled and set in the correct position. However, in order to level the lighting device, an operator must be able to receive feedback regarding whether or not the lighting device is level. Thus, a commercial bubble level is typically attached to the lighting device. The commercial bubble level is usually attached to the lighting device via a separate device, such as a level holder or ring for supporting the level. This means that the operator must attach the separate device to the lighting device each time and remove the separate device when finished with the leveling process. The operator may need to repeat this process for each lighting fixture. This results in extra time spent performing the task, the cost of the separate device, and added error margin due to the attachment of the separate device.

The elements and features shown in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of example embodiments of the present disclosure. Additionally, certain dimensions may be exaggerated to help visually convey such principles.
DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
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 provides a globe clamp which comprises an integrated mounting pad which temporarily holds a commercial level without the need for addition attachment mechanisms or accessories.
As described above, elevated lighting devices often need to be leveled during installation or subsequent maintenance in order to ensure proper alignment of the lighting device and the direction of the emitted light. The present disclosure provides a clamp, or a coupling which, in certain embodiments, holds a light source and couples the light source to a support structure. The support structure may have a slight adjustability of a few degrees (e.g., +/−4° minimum) in all directions, which allows the lighting device to be moved and stabilized within that adjustability range. Since, in certain example embodiments, the goal of adjusting the lighting device is to level the lighting device, a commercially-available bubble level is attached somewhere on the lighting device to provide feedback. The globe clamp disclosed herein includes an integrated mounting pad which can hold a level while a user adjusts the lighting device, providing immediate feedback. Specifically, the user can simply place a commercial level, such as a circular bubble level, onto the mounting pad when performing adjustments, and remove the level when finished. Since the globe clamp does not require additional accessories to hold a level, the leveling process becomes more convenient, time efficient, and cost-saving. The results may even be more accurate since potential error introduced by having to attach an additional leveling accessory to the lighting device is removed.
Turning to the drawings, FIG. 1 illustrates a globe clamp 100 with integrated level mounting pads, in accordance with example embodiments of the present disclosure. Referring to FIG. 1, the globe clamp 100 includes a clamp body having a top portion 102 and a bottom portion 104 coupled to the top portion. The clamp body further includes an exterior contour 106. In certain example embodiments, the top portion 102 and the bottom portion 104 are integral and continuous. In certain embodiments, the exterior contour 106 can include one or more depressions as shown in FIG. 1. The depressions along exterior contour 106 can assist with gripping the globe clamp. In other embodiments, the exterior contour 106 can take other forms such as a flat angled surface that is continuous from the top portion 102 to the bottom portion 104. In the example shown in FIG. 1, the outer surface of the bottom portion 104 also includes alternating flat faces and grooved surfaces for gripping the clamp. In alternate embodiments, the flat faces and grooved surfaces can take other forms and configurations. In certain example embodiments, the top portion 102 includes a first inner surface 108, which defines a first internal opening 110. Likewise, the bottom portion 104 includes a second internal surface 112 which defines a second internal opening 114. In certain example embodiments, the first internal opening 110 is joined with the second internal opening 114 such that the first and second internal openings make up a continuous opening traversing the clamp body. In certain example embodiments, the top portion 102 and the bottom portion 104 are integrally formed and parts of the same body rather than separate parts that are joined together.
In certain example embodiments, the first internal opening 110 is a tubular or round opening. In other example embodiments, the first internal opening 110 is a rectangular or square opening. In yet other example embodiments, the first internal opening 110 has another regular, irregular, geometric, or non-geometric shape. Likewise, the second internal opening 114 can be tubular or round, square or rectangle, or any other regular, irregular, geometric, or non-geometric shape. In certain example embodiments, the first internal opening 110 and the second internal opening 114 are separated such that the first internal opening 110 is a recess in the top portion 102 of the clamp body opening upwards and the second internal opening 114 is a recess in the bottom portion 104 of the clamp body opening downward in the opposite direction of the first internal opening 110.
In certain example embodiments, the second inner surface 112 has threads provided therein for coupling to a support structure received in the second internal opening 114. In certain example embodiments, the second inner surface 112 of the bottom portion 104 provides another coupling mechanism or coupling means for coupling to a support structure in order to mount the globe clamp 100 onto the support structure. In certain example embodiments, the support structure is a housing, a column, a stand, a mount, a riser, or other structure and supports the globe clamp 100. In certain example embodiments, the second internal opening 114 has a larger dimension or perimeter than does the first internal opening 110. For example, in certain embodiments in which the first internal opening 110 and the second internal opening 114 are tubular shaped, the second internal opening 114 may have a larger diameter than does the first internal opening 110. In certain example embodiments, the first internal opening 110 and the second internal opening 114 share a central vertical axis 124 that is parallel to the longitudinal axis of the light fixture to which the globe clamp is coupled.
In certain example embodiments, the globe clamp 100 includes one or more level mounts 116. In certain example embodiments, the level mounts 116 are integrated into the exterior contour 106 of the globe clamp 100. In certain example embodiments, the level mount is a recessed portion of the exterior contour 106. The level mount 116 includes a flat surface 118 on which the level will sit. In certain example embodiments, the level mount 116 includes a wall 120 extending from at least a portion of the perimeter of the flat surface 118. In certain example embodiments, the shape of the flat surface and the wall 120 correspond to a profile or shape of the level such that the level fits within the level mount 116 and is at least partially retained within the level mount 116. In certain example embodiments, the globe clamp 110 includes one or a plurality of level mounts 116 disposed at various locations about the globe clamp 110. In certain example embodiments, the level mount 116 includes a reduced edge 122 which allows a portion of the level to hang off, making it easy to place the level in the level mount 116 and remove the level from the level mount 116. In certain example embodiments, the wall 120 encircles the entire flat surface 118. In certain example embodiments, one or more protrusions (not shown) extend from portions of the perimeter of the flat surface 118, the protrusions configured to retain the level, similar to the function of the wall 120.
In certain example embodiments, the flat surface 118 of the level mount 116 is horizontal with respect to the ground where the lighting device is mounted. Described another way, the flat surface 118 defines a plane that is perpendicular to the central vertical axis 124 of the first internal opening 100, the second internal opening 114, or both. In certain example embodiments, the flat surface 118 is perpendicular to at least a portion of the first inside surface 108.
FIG. 2 illustrates a perspective view of the globe clamp 100 of FIG. 1 as used in a light fixture 200, in accordance with example embodiments of the present disclosure. FIG. 3 illustrates a cross-sectional view of the globe clamp 100 and light fixture 200 of FIG. 2. Referring to FIGS. 2 and 3, in certain example embodiments, the lighting fixture 200 includes the globe clamp 100, a lighting device 202, and a housing 204. In certain example embodiments, the lighting fixture 200 further includes a coupler 206. In certain example embodiments, the lighting device 202 is partially disposed within the first internal opening 110. In certain example embodiments, the lighting device 202 includes a light source 208. In certain example embodiments, the light source 208 and the flat surface 118 of the level mount 116 are substantially parallel. In certain example embodiments the lighting device 202 is a globe light. In certain such example embodiments, the lighting device 202 includes a color globe 210, a lens 212, and an LED as the light source 208. The lighting device 202 may further include a heat-sink 215 for dissipating heat generated by the light source 208.
In certain example embodiments, the globe clamp 100 is coupled to the housing 204 via the second internal opening 114. In certain example embodiments, the globe clamp 100 screws onto the housing 204 via mating threads on the second inner surface and corresponding mating threads on the housing 204. In certain example embodiments, the globe clamp 100 couples to the housing 204 via other coupling mechanisms such as snaps, fittings, and the like. In certain example embodiments, a portion of the lighting device 202 is disposed on top of the housing 204 with an edge secured between the globe clamp 100 and the housing 204. In certain example embodiments, a seal 220 is disposed between the lighting device 202 and the housing 204 such that the junction is sealed. In certain example embodiments, the housing 204 includes an inner chamber 214 in which various electronics, such as a power supply (not shown), can be disposed. In certain example embodiments, the housing 204 further includes a cord fitting 217 through which electronic wires can pass to connect to the electronics within the inner chamber 214 and equipment located below the lighting fixture 200.
In certain example embodiments, the housing 204 is coupled to the coupler 206 via a plurality of set screws 216. Thus, the housing 204 can be adjusted to a certain degree relative to the coupler 206. During adjustment, a user can position the housing 204 relative to the coupler while a level 218 is placed in the level mount 116. The user can adjust the position of the housing while observing the level and secure the set screws when the housing 204 is in a position such that the level 218 indicates the housing is level. In certain example embodiments, the level 218 is a commercially-available radial bubble level. In certain other example embodiments, the level 218 can be any other existing or new type of level suitable for the applications described herein.
