Description

Technical Field

[0001] This invention relates to the field of energy-saving lighting technology, and in particular to an outdoor lighting device and method. Background Technology

[0002] Currently, most outdoor lighting systems, especially fixed streetlights used in public places such as roads and parks, still rely on traditional grid power supply, resulting in continuous and significant electricity consumption. With the promotion of sustainable development concepts, some lighting equipment has begun to incorporate renewable energy supply units, such as independently installing solar collection modules on or near the top of the light pole. However, retrofitting existing streetlights with specific lamp head shapes presents practical difficulties: many streetlights lack a pre-installed vertical pole structure above the lamp head, and the top of the lamp head is often designed as an extended cover or decorative component with a certain curvature. This area is usually unused, and this unique shape makes it difficult to install independent solar power modules without altering the overall structure or appearance of the light pole. Installing them on brackets far from the lamp body would occupy additional space, increase installation complexity and cost, and affect the overall aesthetics and harmony.

[0003] The existing renovation methods have the following main problems: First, for existing streetlights with an arc-shaped extension at the top of the lamp head and no additional upright installation position, there is a lack of a solution that can make full use of the existing structure and achieve a quick and integrated installation of renewable energy collection units; conventional renovation methods often require significant modifications to the original lamp post or the addition of external supports, which is cumbersome, uneconomical, and may affect the strength and stability of the original structure; second, the failure to effectively utilize the space on the arc-shaped upper surface of the lamp head also leaves this potential resource area that is conducive to receiving sunlight idle, limiting the convenience and universality of upgrading existing streetlights to energy-saving standards. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the top of the curved lamp head of the existing street lamp has no upright installation position, which makes it difficult to conveniently and economically install the solar power supply module without changing the original structure, resulting in difficulties in energy-saving transformation of the lighting equipment and waste of surface space resources.

[0005] The above-mentioned technical problems are solved by the following technical solution: This invention proposes an outdoor lighting device, including a lamp post component, which has a straight rod and an arc-shaped rod at the upper end of the straight rod, and a lamp body is installed at the front end of the arc-shaped rod; a battery pack component, which has an arc-shaped frame shell adaptably mounted on the arc-shaped rod, and the lower arc surface of the arc-shaped frame shell is provided with a clamping mechanism for connecting with the arc-shaped rod, and the arc-shaped frame shell contains a plurality of battery cells, each of which is electrically connected to a pre-set electrical connection component in the arc-shaped frame shell through a sliding connection; and a solar energy component, which includes a support rod mounted on the arc-shaped frame shell and a solar panel at the top of the support rod, and the support rod is provided with a drive mechanism for adjusting the orientation of the solar panel.

[0006] In a preferred embodiment of the outdoor lighting device of the present invention: the clamping mechanism includes a through groove extending along the lower arc surface of the arc-shaped frame, a plurality of sliding seats slidably disposed in the through groove, and a clamp hinged to the bottom of each of the sliding seats; the clamp can hug and fix to the outer wall of the arc-shaped rod.

[0007] The clamp includes a first part and a second part that are hinged to each other, and the free ends of the first part and the second part are detachably connected; the inner sidewall of the first part and / or the second part is provided with a receiving groove, and a wedge block is provided in the receiving groove, the wedge block having an inclined surface that mates with the surface of the arc-shaped rod.

[0008] Multiple battery cells are arranged in an arc shape within the arc-shaped frame, such that the first distance between adjacent battery cells on the outer arc side is greater than the second distance on the inner arc side, and the front and rear sides of the arc-shaped frame are open.

[0009] The multiple clamps are spaced apart along the arc length direction of the arc-shaped rod.

[0010] The upper arc surface of the arc-shaped frame is provided with a sliding groove, and the electrical connection component includes an electrical connection piece disposed in the sliding groove; the electrodes of each battery cell are electrically connected to the electrical connection piece through an upper sliding seat that can slide along the sliding groove.

[0011] The driving mechanism includes a first adjustment component and a second adjustment component; the support rod includes a main rod and a crossbar rotatably connected to the top of the main rod, the first adjustment component is used to drive the crossbar to rotate around a vertical axis; the solar panel is rotatably connected to both ends of the crossbar through a mounting bracket, and the second adjustment component is used to drive the solar panel to rotate around a horizontal axis.

[0012] The first adjustment component is a first electric telescopic rod, and the second adjustment component is a second electric telescopic rod.

[0013] The solar panel and the battery pack are connected by a detachable electrical connection, as are the battery pack and the lamp body.

[0014] The present invention also proposes an outdoor lighting method, including the aforementioned outdoor lighting device, and including the following steps: adaptably fixing the arc-shaped frame of the battery pack component to the arc-shaped pole of an existing street light pole through a clamping mechanism at its lower part; Multiple battery cells are installed inside the arc-shaped frame, and each battery cell is electrically connected to the electrical connection component inside the arc-shaped frame through a sliding connection. The support rod of the solar panel is installed on the arc-shaped frame, and the electrical connection between the solar panel and the battery pack is completed. Connect the power supply line of the lamp body to the power connection component of the battery pack; The drive mechanism is used to adjust the orientation of the solar panel according to the ambient light.

[0015] The beneficial effects of this invention are as follows: 1. This invention enables a rapid, stable, and non-invasive retrofit of existing streetlights: Utilizing the existing curved pole of the streetlight as the mounting base, a specially designed, self-adaptive curved frame and a distributed self-locking clamping mechanism securely install the entire power supply module onto this unused structure. This method eliminates the need for destructive construction such as drilling or welding on the light pole, and also eliminates the need for additional space for independent supports, achieving true "install and use." Multiple clamps distributed along the arc length, combined with a wedge-shaped self-locking mechanism, ensure extremely high stability against vibration and loosening in complex outdoor environments, fundamentally solving the safety hazards of unreliable installation of additional equipment.

[0016] 2. Significantly Improved Heat Dissipation Efficiency and Lifespan of Battery Systems: Addressing the heat dissipation challenges of outdoor equipment, this invention cleverly constructs a "chimney effect" heat dissipation channel that conforms to the flow of hot air by arranging individual battery cells in an asymmetrical arc shape within an arc-shaped frame (larger spacing on the outer side and smaller spacing on the inner side), combined with an open design on the front and rear sides of the frame. This active, guided natural convection cooling significantly reduces battery operating temperature compared to traditional sealed or simply perforated battery boxes, effectively slowing down battery capacity decay, improving system safety and overall lifespan, and solving the common heat dissipation problem faced by outdoor energy storage devices.

[0017] 3. Maximizing solar energy collection efficiency and optimizing energy supply: By integrating the solar panel and its dual-axis drive mechanism at the highest point of the curved frame, this invention ensures the power generation unit is in an optimal, unobstructed position. Combined with automatic tracking control based on light sensors, the solar panel can adjust its azimuth and elevation angles in real time, always maintaining the maximum area for receiving sunlight. This highly efficient energy collection capability significantly increases power generation within a limited installation space, providing a more abundant and stable renewable energy source for street lighting, directly enhancing the energy-saving effect after the renovation.

[0018] In summary, the various technical features of this invention are not simply superimposed, but rather deeply synergistic around the core concept of "integrated transformation using curved poles." Stable installation provides a solid foundation for efficient heat dissipation and precise ray tracing; efficient heat dissipation ensures the reliable operation of the energy storage system; and efficient ray tracing enhances energy input. These three elements are interconnected and work together to ultimately achieve a systemic effect of "1+1>2." This solution, with its low cost and simple operation, systematically solves several interrelated technical pain points in existing street light energy-saving retrofits, providing a novel and non-obvious transformation path with outstanding practicality, economy, and significant progress.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0023] Reference Figures 1-6 This embodiment provides an outdoor lighting device, including a lamp post component 1, which has a straight rod 11 and an arc-shaped rod 12 located at the upper end of the straight rod 11, with a lamp body 13 installed at the front end of the arc-shaped rod 12; a battery pack component 2, which has an arc-shaped frame shell 21 adaptably mounted on the arc-shaped rod 12, with a clamping mechanism 22 for connecting to the arc-shaped rod 12 on the lower arc surface of the arc-shaped frame shell 21, and a plurality of battery cells 23 housed within the arc-shaped frame shell 21, each battery cell 23 being electrically connected to a pre-set electrical connection component within the arc-shaped frame shell 21 via a sliding connection; and a solar energy component 3, which includes a support rod 31 mounted on the arc-shaped frame shell 21 and a solar panel 33 located at the top end of the support rod 31, with a driving mechanism 32 on the support rod 31 for adjusting the orientation of the solar panel 33.

[0024] This outdoor lighting installation aims to facilitate the energy-saving retrofitting of existing streetlights, especially traditional streetlights with curved lamp heads. Its core concept is to provide a modular power supply system that can fully utilize the often-unused curved pole section 12 in the original streetlight structure for integrated installation, without requiring structural damage to the main pole or large-scale construction.

[0025] Specifically, the device comprises three main components that work together.

[0026] First, there is the lamp post component 1, which constitutes the existing basic structure of the object to be modified. This lamp post component 1 mainly includes a straight rod 11 as the supporting body, and an arc-shaped rod 12 fixedly connected to the upper end of the straight rod 11. This arc-shaped rod 12 is typically an extension or decorative part of the street lamp head, with a lamp body 13 for providing illumination installed at its front end. The modification of the device of this invention is specifically focused on this arc-shaped rod 12 segment.

[0027] Secondly, there is the battery pack component 2, which is the core module for energy storage and supply. The main body of this battery pack component 2 is an arc-shaped frame, named arc-shaped frame 21. It has baffles on all four sides but no baffles at the front and back. Its curvature is configured to fit or adapt to the outer contour of the arc-shaped pole 12 of the aforementioned lamp post component 1, thus achieving a compatible installation. For a secure connection, a dedicated clamping mechanism 22 is provided on the lower arc surface of the arc-shaped frame 21 (i.e., the side closest to the arc-shaped pole 12). Through this clamping mechanism 22, the entire battery pack component 2 can be firmly clamped and fixed to the arc-shaped pole 12. The internal space of the arc-shaped frame 21 houses multiple battery cells 23 for energy storage. These battery cells 23 are not simply placed, but are electrically connected to pre-installed electrical connection components inside the arc-shaped frame 21 via a sliding connection method. This sliding connection method allows the battery cell 23 to be easily slid into the predetermined position during installation and automatically connect the circuit, while also facilitating the maintenance or replacement of individual batteries.

[0028] Finally, there is the solar panel component 3, which collects solar energy and converts it into electrical energy. This component includes a support rod 31, which is fixedly mounted on the top of the arc-shaped frame 21 of the battery pack component 2, thus integrating the two into one unit. A solar panel 33 is mounted at the top of the support rod 31 to receive sunlight. To maximize solar energy collection efficiency, a drive mechanism 32 is also provided on the support rod 31. This drive mechanism 32 can automatically or controllably adjust the horizontal orientation and tilt angle of the solar panel 33 according to changes in the sun's position (e.g., by acquiring signals through a light sensor), making it as perpendicular as possible to the sunlight, thereby significantly improving photoelectric conversion efficiency.

[0029] The curved pole 12 of traditional streetlights is usually regarded as a purely decorative or structural component, and its potential utilization value has long been overlooked. This invention creatively identifies this specific structure as the key to solving the problem of solar retrofitting of existing streetlights. The reasons are as follows: (1) Spatial adaptability: The curved pole 12 itself provides a physical space with a certain curvature and length extending from the main pole, and this space is usually not occupied by other functional components, providing a basic condition for the installation of additional modules. (2) Advantage of the lighting location: The most prominent point of the curved pole 12 or its arc apex area is usually the part with the highest position in the entire streetlight structure and the least obstruction by the lamp body 13 or other components. Placing the solar energy here can avoid shadow obstruction to the greatest extent and ensure that the solar panel 33 receives sunlight during the optimal time window and radiation intensity. (3) Structural dependency feasibility: As a component of the original lamp post structure, the curved pole 12 has sufficient structural strength to bear the additional load, providing a reliable mechanical support foundation for the additional power supply system. However, directly utilizing this curved rod 12 presents significant challenges: its curved, smooth surface makes it difficult to securely install traditional rigid supports; its limited lateral space (width) and specific curvature require that the additional device be highly integrated and adaptively fit.

[0030] To overcome the above challenges, this invention does not adopt the obvious approach of simply grafting a conventional solar panel bracket onto the arc-shaped rod 12, but instead carries out a series of coordinated and specialized designs. These designs work together to produce technical effects far exceeding the simple superposition of individual designs.

[0031] 1. Arc-shaped frame 21 and distributed adaptive clamping mechanism 22: The core is the design of an arc-shaped frame 21 that is adapted to the curvature of the target arc-shaped rod 12, and is fixed by multiple independent clamps 223 distributed along its lower arc surface. The clamps 223 adopt an adjustable clamping diameter design (such as two-lobed hinge, bolt fastening), and introduce a wedge block 2234 self-locking mechanism.

[0032] Technical problems solved and advantages: (1) Stability and adaptability: Multiple clamps 223 form distributed anchor points, distributing the weight of the equipment and wind load to multiple contact surfaces of the arc-shaped rod 12. Compared with single-point fixation, the anti-overturning and anti-torsion capabilities are significantly enhanced. The wedge block 2234 can automatically wedge tight when vibration causes loosening, providing a continuous and reliable locking force, solving the problem of easy slippage of the clamp on the arc-shaped smooth surface. (2) Wide adaptability: The arc of the arc-shaped frame shell 21 is adjustable or provides multiple specifications. With the sliding lower seat 222 and adjustable clamps 223, the same set of devices can adapt to arc-shaped rods 12 with different curvatures and diameters, realizing "one-click" adaptation and transformation of a wide range of existing street light models, with extremely strong versatility.

[0033] 2. Arc-shaped asymmetrical layout and open heat dissipation structure of battery cells 23: Multiple battery cells 23 are arranged non-equidistantly along the arc inside the arc-shaped frame 21 (the distance between the outer sides is greater than the distance between the inner sides), and the front and rear sides of the arc-shaped frame 21 are designed to be open.

[0034] Technical problems solved and advantages: (1) High-efficiency natural heat dissipation: This layout is not arbitrary, but cleverly utilizes the principle of hot air rising. The heat generated when the battery is working heats the internal air. In the gradually expanding channel formed by the narrow inner slit and the wide outer slit, the hot air has low flow resistance and rises faster, forming a strong "chimney effect" convection with the cold air entering from the front and back. This is a qualitative improvement in heat dissipation efficiency compared to arranging the batteries at equal intervals in a closed or poorly ventilated rectangular box, effectively extending the battery's lifespan and safety in harsh outdoor environments. 2. Space optimization: The asymmetrical layout perfectly matches the arc-shaped internal space of the arc-shaped frame 21, achieving a balance between maximizing battery capacity and optimizing heat dissipation performance within a limited volume.

[0035] 3. Integrated, dual-axis adjustable solar panel 3: The support rod 31 of the solar panel 33 is directly integrated into the highest point of the top of the arc-shaped frame 21, and a dual-axis adjustment system consisting of a first drive mechanism 32 (e.g., horizontal rotation) and a second drive mechanism 32 (e.g., pitch adjustment) is adopted.

[0036] Technical problems solved and advantages: (1) Maximizing light exposure and structural integration: The support point of the solar panel 33 is set at the top of the arc, ensuring that the adjustment mechanism has the best "view" and unobstructed operating space. The entire solar component 3 and the battery pack component 2 are rigidly connected through the arc-shaped frame 21 to form a compact, low-center-of-gravity integrated module, rather than separate solar panels 33 and battery packs, which greatly reduces the overall wind resistance and enhances the structural stability. (2) Automatic optimization of energy harvesting: Combined with a light sensor, the dual-axis drive can realize fully automatic solar tracking, ensuring that the solar panel 33 is always at the best light-receiving angle. Due to the superior position of the mounting base (top of the arc), this tracking adjustment can achieve maximum efficiency, thereby significantly increasing the average daily power generation per unit area of ​​the solar panel.

[0037] In summary, the innovation of this invention does not lie in simply adding solar panels 33 to streetlights, but in creatively identifying the potential value of the long-idle curved pole 12 in existing streetlight structures, defining it as a unique platform for integrated transformation, and designing a highly collaborative and functionally coupled dedicated system around this platform. This system uses a frame structure that fits onto the curved pole 12 as its core carrier, integrating a distributed self-locking clamping mechanism 22, a curved heat dissipation layout for the battery, and a top-integrated dual-axis adjustable solar panel. These designs are not isolated but work together to produce a synergistic technical effect of "1+1>2," systematically solving several interconnected pain points in existing transformation schemes, such as unstable installation, poor adaptability, poor heat dissipation, low light efficiency, and large amount of transformation work.

[0038] Therefore, this invention integrates the battery pack and the intelligently adjustable solar panel 33 into a compact add-on module. This module can be quickly and securely installed in the unused position of the existing street light's curved pole 12 via the clamping mechanism 22, and supplies power to the existing light body 13 through a convenient electrical connection, ultimately achieving a low-cost, high-efficiency, non-intrusive, and widely applicable solar energy-saving retrofit of existing street lights. This concept and design of proposing a complete and optimized solution for a specific structure is not obvious to those skilled in the art, demonstrating outstanding substantive features and significant technological advancements.

[0039] The clamping mechanism 22 includes a through groove 221 extending along the lower arc surface of the arc-shaped frame shell 21, a plurality of sliding seats 222 slidably disposed in the through groove 221, and a clamp 223 hinged to the bottom of each sliding seat 222; the clamp 223 can hug and fix to the outer wall of the arc-shaped rod 12.

[0040] First, the clamping mechanism 22 has a continuous through slot 221 on the lower arc surface of the arc-shaped frame 21 along its arc length. This slot not only provides a mounting base and movement track for the entire clamping system, but also serves as an important structural opening, reducing the overall weight of the arc-shaped frame 21. Second, multiple independent sliding seats 222 are set in the through slot 221 and can slide freely along the arc trajectory in the slot. Each sliding seat 222 acts as an independent connection node, bearing the local load that fixes the arc-shaped frame 21 to the arc-shaped rod 12. This sliding design gives the installation process great flexibility. During installation, the operator can manually adjust each sliding seat 222 to the most suitable and evenly stressed position according to the actual curvature and diameter of the arc-shaped rod 12, and then perform the final locking, thereby ensuring that the clamping force can be evenly distributed and avoiding stress concentration. Finally, a clamp 223 is hinged to the bottom of each sliding seat 222. The clamp 223 is typically composed of two parts and can hug and tighten the outer wall of the arc-shaped rod 12 from both sides like pliers. The hinged connection allows the clamp 223 to adaptively conform to the surface of the arc-shaped rod 12 of different diameters, achieving a tight fit whether the rod is a standard circle or slightly elliptical. By locking the free end of the clamp 223 with bolts or similar fasteners, a strong clamping force is generated, firmly anchoring the sliding seat 222 (and thus the entire arc-shaped frame 21) to the arc-shaped rod 12.

[0041] In summary, the clamping mechanism 22, through its three-stage design of "through groove 221, sliding lower seat 222, and hinged clamp 223", achieves flexible adjustment of the installation position, adaptive fit to different pole diameters, and ultra-high stability through multi-point distributed locking. This design allows the entire power supply auxiliary module to be integrated tightly and reliably onto the existing arc structure of the street light, just like a sturdy "exoskeleton".

[0042] The clamp 223 includes a first part 2231 and a second part 2232 that are hinged to each other, and the free ends of the first part 2231 and the second part 2232 are detachably connected; the inner sidewall of the first part 2231 and / or the second part 2232 is provided with a receiving groove 2233, and a wedge block 2234 is provided in the receiving groove 2233, and the wedge block 2234 has an inclined surface that cooperates with the surface of the arc rod 12.

[0043] The clamp 223 consists of two parts: a first part 2231 and a second part 2232. These two parts are connected at one end to the lower surface of the sliding seat 222 via a hinge or pivot, allowing the clamp 223 to open and close like the jaws of a plier. At the other end, the free end, a detachable connection is designed, typically using a bolted plug-in structure, snap-fit, or direct bolt tightening. This design allows installers to easily wrap the open clamp 223 around the arc-shaped rod 12, align and connect the two free ends, and lock them in place. The operation is extremely convenient, requiring no special tools for basic fixation. Specifically, the thickness of the free end of the second part 2232 gradually decreases, while the free end of the first part 2231 has a cavity. The free end of the second part 2232 can be inserted into this cavity, and tightened by bolts fixed to the first part 2231, achieving a locking and clamping effect between the first part 2231 and the second part 2232.

[0044] To further enhance the reliability and durability of clamping, a receiving groove 2233 is specially formed on the inner sidewall of the first part 2231 and / or the second part 2232 (i.e. the side that contacts the surface of the arc-shaped rod 12). One or more wedge blocks 2234 are provided in the receiving groove 2233. A key surface of the wedge block 2234 is constructed as an inclined surface, which is designed to match the outer surface contour of the arc-shaped rod 12. Its core working principle and advantages are as follows: When the clamp 223 is initially fastened to the arc rod 12, the inclined surface of the wedge block 2234 contacts the surface of the rod. During long-term operation of the equipment, if the clamp 223 shows a slight loosening tendency due to vibration, temperature change or material stress relaxation, that is, when the clamp 223 tends to slide downward relative to the arc rod 12, the reaction force of the surface of the arc rod 12 on the inclined surface of the wedge block 2234 will change accordingly. This reaction force will generate a component force that pushes the wedge block 2234 deeper into its receiving groove 2233. Due to the geometry of the wedge block 2234, it will expand to both sides (radially) while being pushed inward, thereby tightly abutting the side wall of the receiving groove 2233 and generating an outward expansion force on the main body of the clamp 223. This process is equivalent to automatically and dynamically reducing the inner diameter of the clamp 223, thereby compensating for the loose gap and tightening the clamp 223 again. This ingenious design achieves the mechanical effect of "tightening with vibration" or "anti-loosening self-locking", which greatly enhances the stability and safety of the entire device during long-term operation in harsh outdoor environments and avoids the risk of equipment slippage, displacement or even detachment due to loose connections.

[0045] Multiple battery cells 23 are arranged in an arc shape within the arc-shaped frame 21, such that the first distance between adjacent battery cells 23 on the outer arc side is greater than the second distance on the inner arc side, and the front and rear sides of the arc-shaped frame 21 are open.

[0046] Specifically, these battery cells 23 are not arranged in a conventional equally spaced matrix, but rather follow the arc-shaped structure of the arc-shaped frame 21, arranged along the arc direction. This special arc-shaped arrangement results in a key feature: on the outer arc side of the arc-shaped frame 21 (i.e., the more convex side away from the center of the arc-shaped rod 12), the spacing between adjacent battery cells 23 forms a first spacing; while on the inner arc side of the arc-shaped frame 21 (i.e., the side facing the center of the arc-shaped rod 12), the spacing between adjacent battery cells 23 forms a second spacing. The first spacing is intentionally designed to be larger than the second spacing. This asymmetrical spacing layout, which gradually expands from the inside out, directly results in the natural creation of an airflow channel with a gradually expanding cross-section inside the battery pack.

[0047] More importantly, the arc-shaped frame 21 is structurally designed with open front and rear sides, meaning its two large side surfaces are not enclosed by walls. This design, in conjunction with the aforementioned asymmetrical spacing layout, forms a highly efficient passive cooling system. Its working principle is as follows: when the battery operates, it generates heat, which heats the surrounding air. The hot air becomes less dense and naturally rises. Due to the smaller battery spacing on the inner side (inner arc side) (second spacing), the initial flow channel formed in this area is narrower, which helps accelerate the air's ascent. After rising to the top of the battery pack, the hot air flows along a gradually widening channel from the inner side to the outer side (from the second spacing area to the first spacing area). Ultimately, the rising hot air can be smoothly discharged from the open top area and outer arc side of the arc-shaped frame 21. Meanwhile, the complete opening of the front and rear sides of the arc-shaped frame shell 21 ensures that the cold air from the external environment can be fully replenished from the front, rear, and bottom sides without obstruction, forming a continuous convection. This structure-guided airflow from bottom to top and from inside to outside effectively utilizes the "chimney effect" and greatly enhances the efficiency of natural convection heat dissipation.

[0048] Therefore, this layout transforms structural constraints (arc-shaped frame 21) into functional advantages (guided airflow), and together with the open design, it solves the problems of performance degradation, shortened lifespan, and even safety hazards caused by heat accumulation in outdoor enclosed or poorly ventilated environments, demonstrating the ultimate optimization of thermal management efficiency within a limited space.

[0049] Multiple clamps 223 are spaced apart along the arc length of the arc-shaped pole 12. The primary purpose of this spaced-apart design along the arc length is to achieve optimized load distribution and uniform force transmission. Each clamp 223 acts as an independent anchor point, jointly bearing the vertical load formed by the overall weight of the upper arc-shaped frame 21, the battery pack, and the solar panel 3. At the same time, it works together to resist the bending moment and torque generated by lateral forces such as wind loads. By distributing the total load to multiple contact points, excessive stress concentration in local locations of the arc-shaped pole 12 is avoided, greatly reducing the potential adverse effects on the original street light structure and improving the reliability of the installation.

[0050] Secondly, this multi-point interval fixing method greatly enhances the overall stability of the entire additional module on the arc rod 12. Multiple clamps 223 form a series of constraint points along the arc, which together restrict the device's tendency to slide along the tangent direction of the arc rod 12 and its tendency to rotate around the rod, providing multi-dimensional mechanical constraints. This enables the device to maintain a stable position and is not prone to displacement or loosening when facing continuous vibration, thermal expansion and contraction caused by temperature changes, or accidental impacts.

[0051] In practical implementation, the spacing between clamps 223 can be equal, or it can be optimized to be unequal based on the specific curvature, strength characteristics, and center of gravity of the upper component of the arc-shaped rod 12. Installers can flexibly determine the number and spacing of clamps 223 according to site conditions, allowing the clamping mechanism 22 to adapt widely to arc-shaped rods 12 of different lengths and radii of curvature, demonstrating good versatility and adaptability. This distribution method, combined with the self-locking anti-loosening mechanism of the clamps 223, constitutes a robust, durable, and highly adaptable fixing solution.

[0052] The upper arc surface of the arc-shaped frame 21 is provided with a sliding groove 211, and the electrical connection component includes an electrical connection piece 212 disposed in the sliding groove 211; the electrodes of each battery cell 23 are electrically connected to the electrical connection piece 212 through an upper slide block 213 that can slide along the sliding groove 211.

[0053] A long, narrow groove 211 is formed along the arc-shaped contour of the upper arc surface of the arc-shaped frame 21. This groove 211 not only serves as a mechanical guide rail, but also has a contact piece 212, which acts as a circuit conductor, fixedly installed inside. The contact pieces 212 are usually arranged in pairs, corresponding to the positive and negative terminals of the circuit, and extend to appropriate positions on the arc-shaped frame 21 for connection with the external solar panel 3 and the load circuit. During installation, each battery cell 23 has a dedicated upper slide block 213 pre-connected or assembled on its positive and negative electrodes. The upper slide block 213 has a geometry that matches the groove 211, allowing it to be precisely inserted into the groove 211 and slide smoothly along the arc-shaped path within the groove. When the upper slide block 213 is inserted into the groove 211, its internally designed electrical contact components (such as elastic metal contacts) maintain continuous and tight physical contact with the contact piece 212 embedded in the groove 211, thereby achieving a stable electrical connection while mechanically sliding.

[0054] This plug-in electrical connection method, using "slide groove 211 and upper slide block 213," offers several significant advantages. First, it achieves simultaneous electrical connection and mechanical fixation. Installers only need to place the battery cell 23 into the housing, align the upper slide block 213 on its electrode, and push it into the slide groove 211. This simultaneously completes the positioning and fixation of the cell (through the cooperation of the upper and lower slide blocks 222) and its connection to the entire battery pack circuit, greatly simplifying the installation process and avoiding the tedious wiring and screwing operations of traditional methods, thus improving the efficiency and reliability of on-site assembly. Second, this design provides excellent maintainability and expandability. If a battery cell 23 needs to be inspected or replaced, it can be easily removed along the slide groove 211, disconnected from the electrical connection, and taken out without disassembling the entire battery pack or disturbing complex wiring. Furthermore, the continuous design of the slide groove 211 allows for flexible adjustment of the number and position of battery cells 23 within a certain range, providing convenience for adapting to different capacity requirements. Finally, the structure encapsulates the main conductor (connector 212) inside the groove 211, reducing external exposure and facilitating dust and accidental contact prevention, thus improving long-term safety and reliability in outdoor environments. The entire electrical connection system is highly integrated with the physical structure of the arc-shaped frame 21, reflecting the design concept of mechatronics.

[0055] The drive mechanism 32 includes a first adjustment component 321 and a second adjustment component 322; the support rod 31 includes a main rod 311 and a crossbar 312 rotatably connected to the top of the main rod 311. The first adjustment component 321 is used to drive the crossbar 312 to rotate around a vertical axis; the solar panel 33 is rotatably connected to both ends of the crossbar 312 via a mounting bracket 34, and the second adjustment component 322 is used to drive the solar panel 33 to rotate around a horizontal axis. The first adjustment component 321 is a first electric telescopic rod, and the second adjustment component 322 is a second electric telescopic rod.

[0056] The drive mechanism 32 mainly consists of two independent adjustment components, which control the rotation of the solar panel 33 in two different dimensions, thereby achieving omnidirectional angle adjustment. The support rod 31, as the skeleton of the entire solar component 3, adopts a segmented movable design. It includes a main rod 311 fixedly installed on the top of the arc-shaped frame 21, and a crossbar 312 rotatably connected to the top of the main rod 311 via a horizontal pivot. The crossbar 312 can rotate left and right in the horizontal plane around the vertical axis of the main rod 311.

[0057] The function of the first adjustment component 321 is to drive the aforementioned crossbar 312 to rotate horizontally. This first adjustment component 321 is typically a first electric telescopic rod, with one end fixed to the main rod 311 and the output end connected to the crossbar 312. When the first adjustment component 321 is working, it pushes or pulls the crossbar 312, causing it to rotate precisely around the vertical axis to a specified azimuth angle (i.e., an east-west angle). This allows the solar panel 33 to follow the sun's horizontal movement from east to west.

[0058] The solar panel 33 is not directly and rigidly fixed to the crossbar 312, but is rotatably connected to both ends of the crossbar 312 via a mounting bracket 34, allowing the solar panel 33 to tilt up and down around the crossbar 312. The second adjustment component 322 is specifically used to drive the solar panel 33 to tilt and rotate. This second adjustment component 322 is a second electric telescopic rod, whose cylinder or body is usually hinged to the crossbar 312, and the end of its telescopic rod is hinged to the back of the solar panel 33 or the mounting bracket 34. By controlling the extension and retraction of the second electric telescopic rod, the solar panel 33 can be directly pushed to rotate around the crossbar 312, thereby adjusting its tilt angle (i.e., the angle in the direction of the solar altitude angle) to cope with the changes in the sun's altitude at different times of day and in different seasons.

[0059] By coordinating the operation of the first adjustment component 321 controlling the azimuth angle and the second adjustment component 322 controlling the elevation angle, the drive mechanism 32 enables the solar panel 33 to achieve dual-axis, fully automatic tracking of the sun's position. Compared to fixed installations or single-axis adjustment systems, this design significantly increases the daily effective sunshine duration and radiation reception, thereby greatly improving power generation efficiency. Simultaneously, the entire adjustment mechanism is integrated onto the support rod 31, resulting in a compact structure and direct power transmission. Combined with the stable arc-shaped frame base 21 below, this ensures overall stability and reliability during the tracking motion.

[0060] The solar panel 3 and the battery pack 2 are connected by a detachable electrical connection, as are the battery pack 2 and the lamp body 13.

[0061] Specifically, this detachable electrical connection is typically achieved through standardized, mis-plug-proof electrical connectors (such as waterproof plugs and sockets), quick-connect terminals, or connectors with locking mechanisms. Between the solar panel 3 and the battery pack 2, such connectors are used at the terminals of the output cables leading from the solar panel 33, while the battery pack 2 has a corresponding input interface internally connected to the positive and negative terminals 212 in the frame groove 211. During installation, simply aligning and inserting the connectors at both ends completes the circuit connection from the solar panel to the battery pack within seconds, eliminating the need for on-site wire cutting, stripping, or soldering.

[0062] Similarly, a cable with a connector is also led out from the output end of the battery pack between the battery pack component 2 and the original lamp body 13. During the modification, simply insert or connect a matching connector in series or in parallel to the power supply line of the original street light (usually in the junction box near the lamp body 13), or use a quick-connect terminal to connect to the original line. Then, connect the connector of the battery pack output cable to it, thus completing the modification of the power supply circuit.

[0063] This detachable connection method offers several significant benefits. First, it greatly simplifies on-site installation and subsequent maintenance, making the modification work as easy and quick as "assembling building blocks," reducing the professional skills required of operators and shortening construction time. Second, it achieves true modularity. Solar panel 3, battery pack 2, and even the lamp body 13 can be prefabricated, tested, transported, and replaced as independent modules. If a module fails, the electrical connection can be quickly disconnected and replaced without affecting other modules, resulting in excellent maintainability. Finally, it enhances the flexibility of upgrading and adjusting the entire system. For example, if future expansion of battery capacity or replacement with higher-power solar panels is needed, simply disconnect the connection, replace the corresponding module, and reconnect it, giving the system excellent scalability.

[0064] Therefore, the detachable electrical connection design and the mechanical clamping and fixing mechanism complement each other, together forming the core features of this device: "ready to use and flexible maintenance," which is an important guarantee for achieving efficient and low-cost energy-saving retrofitting of existing streetlights.

[0065] Reference Figures 1-6An outdoor lighting method includes an outdoor lighting device and includes the following steps: fixing the arc-shaped frame 21 of the battery pack component 2 to the arc-shaped pole 12 of an existing street light pole via a clamping mechanism 22 at its lower part; installing multiple battery cells 23 inside the arc-shaped frame 21, and electrically connecting each battery cell 23 to the electrical connection component inside the arc-shaped frame 21 via a sliding connection; installing the support rod 31 of the solar panel 3 onto the arc-shaped frame 21, and completing the electrical connection between the solar panel 3 and the battery pack component 2; connecting the power supply line of the lamp body 13 to the electrical connection component of the battery pack component 2; and adjusting the orientation of the solar panel 33 according to the ambient light using a drive mechanism 32.

[0066] Reference Figures 1-6 Step 1: On-site assessment and preparation: First, the existing streetlights to be upgraded are assessed. Key operations include measuring the arc length, radius of curvature, and diameter of the curved pole 12 at the top of the pole. Based on the measurements, a suitable curved frame 21 is selected or configured, and the appropriate number of clamps 223, battery cells 23, and other installation components are prepared. All electrical connectors are ensured to be compatible, and necessary installation tools and safety equipment are prepared.

[0067] Step 2: Install battery pack component 2: Preliminary positioning and clamp 223 installation: Place the arc-shaped frame 21 above the arc-shaped rod 12, aligning the through groove 221 on its lower arc surface with the rod body. Starting from the higher end of the arc-shaped rod 12 (usually near the lamp body 13), install the first clamp 223. Open the clamp 223 so that its two parts encircle the arc-shaped rod 12, insert the free end, and initially tighten the connecting bolts. At this time, the clamp 223 is in a sliding and adjustable state.

[0068] Distributed clamping and fixing: Along the arc length of the arc-shaped rod 12, at predetermined intervals downwards, install the second, third, and finally the last clamp 223 in the same manner. After all clamps 223 are initially in place, make overall adjustments to ensure that the spacing between each clamp 223 is uniform and that the relative position of the arc-shaped frame shell 21 and the arc-shaped rod 12 is centered and fits snugly. Subsequently, tighten all the bolts of the clamps 223 in sequence, so that the clamps 223 tightly hug the rod body. During this process, the wedge-shaped blocks 2234 in the inner receiving grooves 2233 of the clamps 223 have their inclined surfaces in contact with the surface of the rod body, forming an initial pre-tightening.

[0069] Battery cell 23 installation and circuit connection: Battery cells 23 are placed one by one into the arc-shaped frame 21. The lower end of each battery cell 23 is placed into the corresponding sliding seat 222, and then the upper sliding seat 213 connected to its electrodes is aligned and pushed into the groove 211 on the upper arc surface. The upper sliding seat 213 slides within the groove 211 until it reaches the predetermined position, at which point its internal contacts automatically establish an electrical connection with the pre-embedded contact piece 212 within the groove 211. All battery cells 23 are arranged in an arc shape, forming an asymmetrical layout with larger spacing on the outer sides and smaller spacing on the inner sides.

[0070] Step 3: Install solar panel component 3: Mechanical installation: Align the bottom of the support rod 31 of the solar component 3 with the mounting base that is fixed to the top of the arc-shaped frame 21, insert it and fix it rigidly with bolts.

[0071] Electrical connection: Connect the waterproof connector at the end of the output cable of the solar panel 3 to the corresponding input interface connector led out from the terminal piece 212 of the battery pack component 2 and lock it in place to complete the circuit connection for the solar panel 33 to charge the battery pack.

[0072] Step 4: System Electrical Integration and Commissioning Load circuit modification: Connect the matching quick-connect terminal block or connector to the power supply line of the existing street light body 13 (usually at the junction box). Then, connect the power supply cable from the output end of the battery pack component 2 (also led out through the connector 212) to it to complete the power supply modification of the lighting load.

[0073] Control system activation: Ensure that the light sensor signal line on the solar panel 33 and the control line for the electric telescopic rod driving the first adjustment component 321 and the second adjustment component 322 are connected to the controller. After power is supplied, the controller will automatically start working according to the preset program or the light sensor signal.

[0074] Functional testing: Solar tracking test: Observe whether the first adjustment component 321 drives the horizontal bar 312 to rotate horizontally to adjust the azimuth angle under changes in light, and whether the second adjustment component 322 drives the solar panel 33 to rotate in pitch to adjust the elevation angle, to ensure that the dual-axis automatic tracking function is normal.

[0075] Charge and discharge test: During the day, verify the charging status of the solar panel 33 to the battery pack, and at night or in a simulated dark environment, verify whether the battery pack can automatically switch and supply power to the lamp body 13 normally.

[0076] Step 5, Final Inspection and Delivery: Check the tightness of all mechanical connections and confirm that electrical connections are free of exposed wires and have good insulation. Clean the installation site. The system enters automatic operation mode, realizing the energy-saving upgrade of the existing streetlights. This method, through modular installation, distributed mechanical fixing, sliding electrical connections, and automatic light tracking, achieves a fast, safe, and reliable upgrade process, as well as efficient energy harvesting and utilization during operation.

[0077] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
