Technical Field
[0001] The embodiments herein generally relates to a street light assembly, and more particularly, to assembling components that include a boom, a housing, a solar panel, and a battery of a solar street light assembly on top of a pole using a single multi-functional bolt in a simple and speedy manner.
Description of the Related Art
[0002] A street light, lamp post, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or walkway, which is turned on or lit at a certain time when illuminance levels (e.g., LUX levels) drop below a specified value (e.g., 120). They may be powered by alternative energy sources, including wind and solar power. Solar street lights are powered by photovoltaic panels generally mounted on a lighting structure. Such photovoltaic-powered LED luminaires are gaining wider acceptance. The photovoltaic panels charge one or more rechargeable batteries via electronic and electrical arrangements, which powers, via electronic and electrical arrangements, a fluorescent or LED lamp during the night. Typical solar street light subassemblies include a solar panel, a lighting fixture (e.g., an arrangement of light emitting diodes), a rechargeable battery, a charge control and driver electronics, and a boom. The entire solar street light subassemblies are mounted on top of a pole using multiple bolts, nuts, and/or washers, typically at a height of minimum 3 meters from the ground level.
[0003] Each component, and/or sub-subassembly of the solar street light subassemblies has its own set of bolts to assemble the solar street light. It is cumbersome to assemble each component; and/or sub-subassembly of the solar street light subassemblies on top of the pole using multiple bolts, nuts, and/or washers, at each installation site. Also, it is a time consuming process. For example, typically, a component (e.g., the boom) is attached to the pole at certain angle with respect to the ground level using various clamping bolts. In another example, a sub-subassembly (e.g., the solar panel) may require multiple sets of bolts, nuts, and/or washers to assemble them on top of the pole in a direction facing the sunlight. In yet another example, a battery housing component may require multiple sets of bolts, nuts, and/or washers to assemble either on the pole or away from the pole. Hence, installation of the solar street light components, and/or subassemblies on top of the pole is a complex and time consuming process that also requires expertise. Accordingly, there remains a need for a solar street light assembly that includes components, and/or subassemblies which can be fixed on top of a pole in a simple and speedy manner.

[0019] FIG. 2 illustrates a solar street light assembly 200 that includes the pole 102 of FIG. 1 and a clamping bolt 202 for mounting components of the solar street light assembly 200 on top of the pole 102 according to one embodiment of the present disclosure. Components of the solar street light assembly 200 includes, but not limited to, a battery 204, a solar panel 206, a housing 208 that accommodates the battery 204 and the solar panel 206, an arm 210 that holds a lighting fixture (herein afterwards refers to boom), a luminaire 212 and a battery holder 214. In one embodiment, the components such as the solar panel 206, the housing 208, the boom 210, the luminaire 212, and the battery holder 214 are fixed on the site prior to fixing the battery 204. The battery 204 may be then fixed using two hexagonal headed tie rods, and a battery clamp (not shown in the FIG. 2). The battery 204 may store electrical energy that is generated during the daytime by the solar panel 206, and may provide energy to a lighting fixture (e.g., an arrangement of light emitting diodes) at the luminaire 212 for illumination during the night. Embodiment of FIG. 2 depicts the solar street light assembly 200 that includes a single battery 204. However, it is to be understood that the solar street light assembly 200 can include more such battery.
[0020] In one embodiment, the solar panel 206 may be rotated 360 degrees with respect to a vertical axis of the boom 210, or the pole 102. The solar panel 206 may be rotated and fixed at a pre-determined angle which may be defined at the time of manufacture using the clamping bolt 202. In one embodiment, the solar panel 206 is fixed at the pre-determined angle based on a direction facing the sun light. In one embodiment, the solar panel 206 is pre-assembled to the housing 208 during manufacturing and assembling processes.
[0021] The housing 208 includes one or more elongated portions such as a first elongated portion 218 and a second elongated portion 220, and a hollow portion 221 between the first elongated portion 218 and the second elongated portion 220. The one or more elongated portions are located at a side of the hollow portion 221. The hollow portion 221 accommodates the top end 120 of the pole 102. The hollow portion 221 further includes a top end 222 that includes an aperture 223 (depicted using hatch lines in the FIG. 2) that is aligned with the slot 122 (depicted using parallel lines in the FIG. 2) at the pole 102. In one embodiment, the hollow portion 221 resembles an inverted cylindrical shape. However, it is to be understood that the hollow portion 221 can resemble any shape (e.g., a cone). The clamping bolt 202 is fixed through the aperture 223 and the slot 122 to fix the housing 208 with the pole 102.
[0022] In one embodiment, the solar street light assembly 200 includes a controller charges and/or discharges the battery 204. The controller further turns ON and/or OFF a lighting fixture fitted within the luminaire 212. The controller may be sealed with a protective casing 224 which prevents it from environmental damages (e.g., battery fumes).
[0023] The boom 210 includes a first end 225 and a second end 226. The first end 225 of the boom 210 includes a protrusion 227 which is placed between an elongated portion (e.g., the first elongated portion 218 or the second elongated portion 220) of the housing 208 and the boss plate. An embodiment of FIG. 2 depicts the protrusion 227 is placed between the first elongated portion 218 and the boss plate. However, the protrusion 227 can also be placed between the second elongated portion 220 and the boss plate to fix the boom 210. Further, in an embodiment, a portion of the first elongated portion 218 or the second elongated portion 220 of the housing 208 is mounted on the first end 225 of the boom 210.
[0024] In one embodiment, an elongated portion (e.g., the first elongated portion 218, or the second elongated portion 220) which is mounted on the first end 225 holds the boom 210 on the pole 102. In one embodiment, the boom 210 is mounted on the pole 102 at an angle that may vary from a first degree to a second degree (e.g., 10 to 80 degrees) with respect to a ground level. In one embodiment, the boom 210 is mounted on the pole 102, and set perpendicular to a flow of traffic on the road or pathway below on the ground. In one embodiment, the boom 210 can be made up of plastic or metal. The boom 210 is integrated with the luminaire 212. The luminaire 212 may be used as a lighting source of the solar street lighting assembly 200, and is fixed at a predetermined angle (e.g., perpendicular) with respect to the flow of traffic on the road or pathway below on the ground. With respect to the boom angle (i.e. an angle at which the boom 210 is mounted on the pole 102), the luminaire 212 projects light without causing light pollution at all by using fixed eye-lids, to enhance aesthetics as deemed fit for a particular design.
[0025] An embodiment of FIG. 2 depicts the solar street light assembly 200 that includes the single boom 210, and the single luminaire 212. However, it is to be understood that the solar street light assembly 200 may include more than one boom, and more than one luminaire that are assembled together without the need for multiple connecting assemblies (e.g., multiple bolts, nuts, and/or washers). In one embodiment, the pole 102 and the boom 210 may include a locking mechanism so that when they are intact, they are locked together. In another embodiment, the pole 102 and the boom 210 may be welded together.
[0026] The battery holder 214 holds the battery 204 within the housing 208. The size and shape of the battery holder 214 may vary based on the size and shape of a battery that is used for powering the lighting fixture, in one example embodiment. The battery holder 214 may include an opening 228 (depicted using dotted lines in the FIG. 2) which is aligned with the aperture 223 at the housing 208, and the slot 122 at the pole. The battery holder 214 may be integrated to the housing 208.
[0027] When the clamping bolt 202 is fixed through the opening 228, the aperture 223, and the slot 122 which are all aligned with each other, the housing 208 is fixed with the pole 102. Also, when fixing the clamping bolt 202, an elongated portion (e.g., the first elongated portion 218 or the second elongated portion 220) of the housing 208 which is mounted on the first end 225 of the boom 210 presses the boom 210 against the boss plate of the pole 102. Thus, the boom 210 which includes the protrusion 227 is fixed between the housing 208 and the boss plate. The clamping bolt 202 also secures the battery 204 and the solar panel 206 which may be accommodated within the housing 208 on top of the pole 102. The battery 204 and the solar panel 206 may be mounted at any side of the pole 102, in one example embodiment. In one embodiment, the solar panel 206 is hinged open when the clamping bolt 202 is fixed.
[0028] In one embodiment, the clamping bolt 202 may include an opening/hole (not shown in the FIG. 1) along its axis and right throughout the clamping bolt 202 which allows main wiring to pass through from the ground level within the pole 102. In one embodiment, a length of the clamping bolt 202 may be 1 inch. However, the length of the clamping bolt 202 can be customized as per requirements of the solar street light assembly 200. Embodiment of FIG. 2 depicts a location of the clamping bolt 202 is in close proximity to the battery holder 214 and the hollow portion 221 of the housing 208. However, the clamping bolt 202 may be fixed anywhere in the solar street light assembly 200 (e.g., in close proximity to the boss plate).
[0029] FIG. 3 is a front view illustrating a first end 225 of the boom 210 which is mounted between the first elongated portion 218 of the housing 208 and the boss plate when the clamping bolt 202 is fixed through the opening 228, the aperture 223, and the slot 122 according to one embodiment of the present disclosure.
[0030] FIG. 4 is a flow chart illustrating a method for mounting components of the solar street light assembly 200 of FIG. 2 on top of the pole 102 according to one embodiment of the present disclosure. In step 402, the boom 210 is mounted on the pole 102 at a predetermined angle with respect to a flow of traffic on the road or pathway below on the ground. In step 404, the housing 208 which includes the hollow portion 221 is fixed to accommodate the top end 120 of the pole 102. In step 406, the solar panel 206, at the housing 208, is adjusted to a pre-determined angle. In step 408, the bolt 202 is clamped through the aperture 223 and the slot 122 to fix the housing 208 with the pole 102. The protrusion 227 may be fixed between an elongated portion (e.g., the first elongated portion 218 or the second elongated portion 220) of the housing 208 and the boss plate when the bolt 202 is clamped.
[0031] Typical solar street light assembly which includes multiple bolts, nuts, and/or washers for mounting various components of the street light assembly in an orientation on top of the pole 102 are reduced to just one bolt (i.e., the clamping bolt 202). A process of installation of the solar street light assembly 200 at each installation site is extremely simple with the clamping bolt 202. Therefore, a lot of time is reduced on installation part. The clamping bolt 202 may include an opening which allows the main wiring to pass through from a ground level within the pole 102. The clamping bolt 202 is hidden from public view, and hence there is a significant enhancement in aesthetic appeal. Disassembling components of the solar street light assembly 200 is also easy with the clamping bolt 202.
[0032] The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the appended claims.
