Description

Technical Field

[0001] This utility model relates to the field of lighting product technology, and in particular to a heat dissipation component and a square tower light. Background Technology

[0002] Existing lighting fixtures all generate heat during use, especially high-power fixtures. Prolonged continuous illumination can lead to severe overheating, damaging electronic components such as circuit boards and reducing their lifespan. Therefore, high-power lighting fixtures require additional heat dissipation components to assist in heat dissipation. However, current lighting fixtures typically use heat dissipation fins integrated into a metal lampshade. These fins are cast as a single piece and cannot be disassembled; when the lampshade fails, only the heat dissipation fins are discarded. Furthermore, the inability to remove the fins from lampshades of different sizes makes it impossible to adjust the fins accordingly, resulting in low adaptability. In addition, existing heat dissipation fins have a single connection method, hindering quick assembly and disassembly and flexible combination, making it inconvenient to adjust the heat dissipation area or replace damaged parts. Moreover, traditional heat dissipation structures lack effective auxiliary locking mechanisms, making them prone to loosening under vibration, affecting heat dissipation efficiency and lifespan.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of a utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] In existing technologies, high-power lighting fixtures generally employ a heat sink fin structure integrally molded with the lampshade. This fixed connection method prevents the heat sink component from being disassembled and maintained independently. When the lamp housing needs replacement due to partial damage, the entire heat sink structure must be scrapped, resulting in resource waste. Especially during the production of lamps of different sizes, the fixed heat sink fins cannot be flexibly adjusted in number according to the lamp body size, leading to compatibility issues such as redundant heat sink structures in small lamps and insufficient heat sink capacity in large lamps.

[0024] Reference Figures 1 to 2This utility model provides a heat dissipation assembly, including a first fin 100, which includes a first body 110 and a first connecting portion thereon; second fins 200, at least two of which are sequentially connected along the radial direction of the first fin 100, each second fin 200 including a second body 210 and a second connecting portion thereon, the second connecting portion being disposed on the same side as the first fin 100; and a connection structure including a first connecting groove 121 and a second connecting groove 121. The first connecting groove 222 and the first plug-in 221 are provided. The first connecting groove 121 is disposed on the first connecting part, and the first plug-in 221 and the second connecting groove 222 are both disposed on the second connecting part. The first plug-in 221 is disposed on the same side as the first fin 100, and the first connecting groove 121 and the first plug-in 221 are matched and plugged in. The second connecting groove 222 is disposed on the same side as the first plug-in 221 of the adjacent second fin 200, and the second connecting groove 222 is matched and plugged in with the first plug-in 221 of the adjacent second fin 200.

[0025] The first connecting part refers to a mechanical connection structure located at the edge of the first body 110, which can be implemented using an extension plate perpendicular to the plane of the body. The surface of this extension plate has a connecting groove for receiving the plug-in component. The second connecting part refers to a mating structure located at the edge of the second body 210, which can be implemented using an extension plate symmetrically arranged with the first connecting part. Its surface simultaneously has a plug-in component and a connecting groove to form a bidirectional connection interface. The first connecting groove 121 is a concave structure for accommodating the plug-in component, which can be implemented using a trapezoidal cross-section through groove, enhancing connection stability through a beveled fit. The second connecting groove 222 is a mating structure located on the connecting surface of adjacent second fins 200, which can be implemented using a groove of the same specifications as the first connecting groove 121, forming a continuous connection channel. The first plug-in component 221 is a convex structure that mates with the connecting groove, which can be implemented using a trapezoidal cross-section metal protrusion.

[0026] Specifically, the first fin 100 serves as the basic heat dissipation unit, and is axially fixed to the connector of the second fin 200 via a connecting groove on its first connecting part. When the heat dissipation area needs to be expanded, the second fin 200 is radially connected to the connector of the adjacent second fin 200 via its own second connecting groove 222. This dual connection mechanism allows multiple second fins 200 to be sequentially expanded and assembled in the radial direction while maintaining the parallel arrangement between the fins. During the insertion process, the trapezoidal cross-section connector and the connecting groove form a self-locking structure to prevent loosening of the connection. The independent assembly of each fin allows the number of second fins 200 to be increased or decreased according to the size of the lamp, and damaged parts can be replaced individually by reverse insertion and removal when maintenance is required.

[0027] Beneficially, this solution utilizes a detachable plug-in structure, allowing the heat dissipation fins to form independent functional modules. This not only adapts to the heat dissipation requirements of lamps of different sizes but also enables individual replacement of damaged components during maintenance. The trapezoidal cross-section connecting components ensure mechanical strength while simplifying the assembly process, avoiding thermal deformation problems caused by traditional welding processes, and achieving modular assembly of the heat dissipation components. The number of heat dissipation fins can be flexibly adjusted according to the size of the lamp. The fins are connected via standardized interfaces, reducing production and maintenance costs. The plug-in structure ensures that the heat dissipation unit can be disassembled and replaced individually, avoiding resource waste caused by the scrapping of the entire unit. The self-locking characteristics of the connecting components maintain the overall stability of the heat dissipation structure, ensuring heat dissipation performance during long-term use.

[0028] Specifically, as shown in the figure, the first connecting groove 121 and the second connecting groove 222 are both grooves with trapezoidal cross-sections, and the first plug-in 221 has a trapezoidal cross-section that matches the first connecting groove 121 and the second connecting groove 222.

[0029] It is understandable that a trapezoidal groove refers to a groove-shaped structure with a trapezoidal concave cross-section along the insertion direction, which can be formed by stamping or milling, with its two sloping sides forming guide surfaces. A trapezoidal connector refers to a protruding structure with a cross-sectional shape complementary to the groove, achieved through injection molding or extrusion molding. The symmetrical design of the trapezoidal cross-section ensures that the sloping sides of the connector make uniform contact with the sloping surfaces of the groove during insertion, creating a self-locking effect.

[0030] Specifically, when the connector is inserted into the slot, the two inclined surfaces press against each other, generating a radial constraint force that prevents the connector from moving in the opposite direction of insertion. The symmetry of the trapezoidal structure ensures that the connector can only be inserted in a single direction, preventing incorrect installation. During insertion, the friction generated by the contact of the inclined surfaces gradually increases until the connector is fully embedded in the slot. At this point, the bottom edge of the trapezoidal section forms a limit with the bottom of the slot, preventing lateral displacement.

[0031] Beneficially, this application utilizes the beveled fit of the trapezoidal cross-section to form a mechanical interlock through geometric constraints, achieving a stable connection without the need for additional fasteners. This solves the problem of easy loosening of the heat dissipation component connection structure and enables rapid assembly and disassembly. The beveled fit of the trapezoidal cross-section automatically generates constraint force during the insertion process, avoiding the use of auxiliary fasteners such as bolts or clips, thus simplifying the assembly steps. The symmetrical design of the connector and the slot ensures a unique installation direction, reducing operational complexity and facilitating quick on-site adjustment of the number and position of the heat dissipation fins.

[0032] Furthermore, at least two first connecting grooves 121 and second connecting grooves 222 are arranged at intervals along the length direction of the first connecting portion.

[0033] According to some embodiments of this application, the first fin 100 is provided with a third extension plate 130, the third extension plate 130 is disposed between two first connecting portions, the third extension plate 130 is perpendicular to the first body, and the third extension plate 130 is used for the first body to be mounted on the lamp. Furthermore, the second fin 200 is provided with a fourth extension plate 230, which is disposed between the two second connecting parts. The fourth extension plate 230 is perpendicular to the second body and is used for mounting the second body onto the lamp.

[0034] The third extension plate 130 refers to a plate-like structure extending from the body of the first fin 100, located between the two first connecting parts. It can be perpendicularly connected to the first body using stamping or welding. Its function is to provide the first fin 100 with an installation interface independent of the connecting structure, allowing the first body to be directly fixed to the surface of the lamp. The fourth extension plate 230 refers to a plate-like structure extending from the body of the second fin 200, located between the two second connecting parts. It can be perpendicularly fixed to the second body using bending or bolting. Its function is to provide the second fin 200 with an installation interface independent of the connecting structure, allowing the second body to be directly fixed to the surface of the lamp.

[0035] Specifically, the third extension plate 130 and the fourth extension plate 230 are perpendicular to the first body and the second body, respectively, forming mounting surfaces perpendicular to the plane of the heat dissipation fins. For example, the third extension plate 130 can be connected to the mounting plate of the luminaire by screws passing through its pre-set mounting holes, and the fourth extension plate 230 can be fitted with the mounting slot of the luminaire using a snap-fit ​​structure. By selecting to use the third extension plate 130 or the fourth extension plate 230 alone, or both simultaneously, the installation requirements at different locations on the luminaire surface can be accommodated. The spatial separation design of the extension plates and the connecting parts allows the heat dissipation fins to be independently fixed to the luminaire via the extension plates while being assembled through the connecting structure, preventing the entire heat dissipation assembly from falling off due to loosening of the connecting structure.

[0036] This solution uses an extension plate independent of the connection structure to create a modular and detachable connection between the heat dissipation component and the lamp. This not only allows for the individual replacement of heat dissipation fins or lamp covers, but also enables the adjustment of the number of heat dissipation fins corresponding to the extension plate to accommodate lamps of different sizes. This achieves flexible assembly and disassembly of the heat dissipation component and the lamp, solving the resource waste problem caused by the traditional integrated structure. At the same time, the modular extension plate design allows the heat dissipation fins to be expanded or reduced according to the size of the lamp, improving the versatility and adaptability of the heat dissipation component.

[0037] According to some embodiments of this application, an auxiliary locking structure 300 is further proposed. The auxiliary locking structure 300 includes a first snap-fit ​​hole 310 disposed on a first body and a second body, and a first snap-fit ​​plate 320 disposed on a fourth extension plate 230. The first snap-fit ​​plate 320 on the second body closer to the first fin 100 passes through the first snap-fit ​​hole 310 on the first body and can abut against the third extension plate 130. The first snap-fit ​​plate 320 on the second body farther from the first fin 100 passes through the first snap-fit ​​hole 310 on the adjacent second body and can abut against the fourth extension plate 230.

[0038] The first snap-fit ​​hole 310 refers to a through-hole structure formed on the first or second body, which can be formed by stamping or cutting processes, and is used to accommodate the first snap-fit ​​plate 320 and form a physical limit. The first snap-fit ​​plate 320 refers to a plate-like structure extending from the fourth extension plate 230, which can be integrally formed with the fourth extension plate 230 by bending processes, and achieves mechanical interlocking by penetrating the snap-fit ​​holes of adjacent components. The third extension plate 130 refers to a vertical extension portion provided on the first body, which can be formed by stamping, and is used to abut against the first snap-fit ​​plate 320 to limit displacement. The fourth extension plate 230 refers to a vertical extension portion provided on the second body, which can be formed by bending, and is used to provide an installation base for the first snap-fit ​​plate 320 and abut against adjacent components.

[0039] Specifically, when the second fin 200 approaches the first fin 100, the first snap-fit ​​plate 320 on its fourth extension plate 230 is inserted into the first snap-fit ​​hole 310 on the first body, so that the end of the first snap-fit ​​plate 320 contacts the third extension plate 130, forming a rigid constraint to prevent radial movement. When the second fin 200 moves away from the first fin 100, the first snap-fit ​​plate 320 on its fourth extension plate 230 is inserted into the first snap-fit ​​hole 310 on the second body of the adjacent second fin 200, and abuts against the fourth extension plate 230 of the second fin 200, forming a chain-locking structure. Through the dual action of penetrating snap-fit ​​and abutment, each fin is fixed in both the axial and radial directions, while the engagement of the snap-fit ​​plate and the snap-fit ​​hole allows for rapid separation.

[0040] This solution utilizes a mechanically interlocking snap-fit ​​structure to achieve non-destructive assembly and disassembly while maintaining connection strength. Existing single-fixation methods are prone to loosening due to thermal stress. This solution, through a regional locking design between the core and outer layers, disperses stress and enhances overall stability, enabling rapid assembly and disassembly of the heat dissipation fins and preventing a decrease in heat dissipation efficiency due to loose connections. The through-hole engagement of the snap-fit ​​plate and snap-fit ​​holes ensures that the fins remain tightly connected even during thermal expansion. The chain-locking structure creates a self-stabilizing system for the outer fins, allowing for installation of different sized lampshades without additional reinforcement.

[0041] According to some embodiments of this application, the first snap-fit ​​plate 320 includes a first connecting segment 321 and a second connecting segment 322. The second connecting segment 322 is set at an angle to the first connecting segment 321. The first connecting segment 321 can abut against the third extension plate 130 and the fourth extension plate 230. The second connecting segment 322 forms a guide portion of the first snap-fit ​​plate 320. Both the third extension plate 130 and the fourth extension plate 230 are provided with mounting holes.

[0042] The first connecting section refers to the part of the snap-fit ​​plate that contacts the extension plate and forms a locking action. It can be implemented using a rectangular plate structure, with its length parallel to the surface of the extension plate, increasing the locking area through planar contact. The second connecting section 322 refers to the part of the snap-fit ​​plate that forms an inclined angle with the first connecting section. It can be implemented using a trapezoidal inclined surface structure, with an inclination angle of, for example, 30° to 60°, guiding the snap-fit ​​plate into the snap-fit ​​hole. The mounting hole refers to the through hole provided on the third extension plate 130 and the fourth extension plate 230. It can be implemented using a circular or square hole structure, and a bolt is passed through the mounting hole to achieve a fixed connection with the lamp.

[0043] Specifically, during assembly, the inclined surface of the second connecting segment 322 is inserted into the snap-fit ​​hole. Guided by the inclined surface, the first connecting segment moves along a predetermined path until it is fully in contact with the surface of the third extension plate 130 or the fourth extension plate 230. At this point, surface contact is formed between the first connecting segment and the extension plate, preventing the snap-fit ​​plate from detaching due to vibration. Mounting holes are located in areas of the extension plate away from the main body; for example, two symmetrical circular holes are opened at the end of the extension plate. Bolts pass through these holes and engage with the threaded holes of the lamp fixture to secure the heat dissipation component to the lamp fixture.

[0044] This solution utilizes mounting holes for detachable bolt connections, accommodating different lighting fixture mounting interfaces while avoiding deformation issues caused by welding. It also ensures precise guidance during snap-fit ​​plate insertion, reducing assembly difficulty, and surface contact locking enhances connection stability. The mounting holes allow the extension plate to quickly adapt to the installation requirements of various lighting fixtures, preventing installation failures due to manufacturing errors.

[0045] According to some embodiments of this application, the auxiliary locking structure 300 further includes a second snap-fit ​​hole 330 disposed on the first body and the second body, and a second snap-fit ​​plate 340 disposed on the second body. The second snap-fit ​​plate 340 on the second body closer to the first fin 100 can be connected to the second snap-fit ​​hole 330 on the first body, and the second snap-fit ​​plate 340 on the second body farther away from the first fin 100 can be connected to the second snap-fit ​​hole 330 on the adjacent second body.

[0046] The second locking hole 330 refers to a through-hole structure provided on the first or second body. Specifically, it can be formed into a diamond shape by stamping or cutting processes, and is used to cooperate with the locking part of the second locking plate 340 to form a mechanical lock. The second locking plate 340 refers to an elastic metal sheet provided on the second body. Specifically, it can be formed into a plate-like structure with a locking part by bending processes. The locking part can form an interference fit with the edge of the second locking hole 330, thereby limiting the relative displacement between adjacent fins.

[0047] Specifically, when the second fin 200 is connected to the first fin 100 or an adjacent second fin 200 via a connector, the second snap-fit ​​plate 340 is pressed into the corresponding second snap-fit ​​hole 330. The snap-fit ​​portion and the edge of the hole undergo elastic deformation to form a snap-fit ​​fixation. The second snap-fit ​​plate 340 closer to the first fin 100 connects to the second snap-fit ​​hole 330 on the first body, forming a first-level locking; the second snap-fit ​​plate 340 farther from the first fin 100 connects to the second snap-fit ​​hole 330 of the adjacent second fin 200, forming a second-level locking. Thus, the multi-level locking mechanism reduces the risk of connection loosening due to thermal expansion or vibration by dispersing stress concentration at the connection points.

[0048] This solution adds a second snap-fit ​​hole 330 and a second snap-fit ​​plate 340 to the plug-in connection, superimposing a mechanical locking function to form redundant fixation. This significantly improves the reliability of the connection node under complex working conditions, effectively suppresses relative sliding or misalignment between fins, and ensures that the heat dissipation components maintain stable physical contact during thermal cycling, thereby maintaining heat dissipation efficiency and extending service life.

[0049] Specifically, as shown in the figure, the second snap-fit ​​hole 330 has a rhomboid structure, and the end of the second snap-fit ​​plate 340 is provided with a snap-fit ​​part, which can abut against the edge of the second snap-fit ​​hole 330.

[0050] It should be noted that the rhomboid structure refers to a quadrilateral hole with four sides of equal length and adjacent sides forming acute and obtuse angles, which can be formed by stamping or milling. This structure provides multi-directional restraint for the locking part through four symmetrically distributed sides. The locking part refers to the protruding structure located at the end of the second locking plate 340, which can be formed by stamping an elastic metal sheet. This protrusion deforms when inserted into the rhomboid hole, forming multi-point contact with the edge of the hole.

[0051] Specifically, during the insertion of the second snap-fit ​​plate 340 into the diamond-shaped hole, the snap-fit ​​portion undergoes elastic bending due to pressure from the hole wall. Once the snap-fit ​​portion is fully inserted into the hole, the elastic restoring force creates four contact points with the four sides of the diamond-shaped hole. The long diagonal of the diamond-shaped hole guides the insertion direction of the snap-fit ​​plate, while the short diagonal restricts lateral displacement. Under vibration or thermal deformation conditions, the four contact points share the load, preventing structural failure caused by stress concentration at a single point.

[0052] In some specific embodiments, the snap-fit ​​portion can be designed as a trapezoidal protrusion with an arc-shaped transition, the width of which is slightly smaller than the short diagonal length of the rhomboid hole. During assembly, the snap-fit ​​portion slides into the hole along the long diagonal direction until the arc-shaped surface is completely fitted with the acute angle edge of the rhomboid hole.

[0053] Compared to existing technologies, traditional snap-fit ​​structures often use circular holes with cylindrical snap-fit ​​parts, which pose a risk of circumferential sliding. In contrast, the use of diamond-shaped holes with a flat plate structure featuring snap-fit ​​parts creates four-point contact through geometric constraints, significantly improving shear resistance. Compared to square hole structures, the long-side guiding characteristics of diamond-shaped holes reduce assembly difficulty, preventing rigid collisions between the snap-fit ​​part and the hole wall, and effectively preventing the heat sink fins from loosening or falling off during vibration or temperature changes. The four-point contact mechanical distribution enhances the stability of the connection structure, the guiding characteristics of the diamond-shaped holes simplify assembly operations, and the deformation compensation capability of the elastic snap-fit ​​part can adapt to dimensional changes under different operating conditions.

[0054] like Figure 3 and Figure 4 As shown, this utility model embodiment also provides a square tower crane light, including the aforementioned heat dissipation component, square lampshade 400, lighting element, connecting bracket 500, and control module. The square lampshade 400 has a rectangular mounting plate 410 and a mounting cavity. The heat dissipation component is fixed on the rectangular mounting plate 410, the lighting element is installed in the mounting cavity, the connecting bracket 500 is rotatably connected to the rectangular mounting plate 410, and the control module includes a controller 700 and a mounting bracket 600. The mounting bracket 600 is fixedly connected to the rectangular mounting plate 410, and the controller 700 is mounted on the mounting bracket 600.

[0055] Specifically, the heat dissipation component is detachably fixed to the rectangular mounting plate 410 of the square lampshade 400, allowing the heat dissipation fins to be independently replaced or adjusted in number. The mounting cavity is designed as a closed space to house the lighting components and isolate them from the external environment, ensuring the stability of the lighting function. The connecting bracket 500 is connected to the lampshade via a rotatable structure, allowing for overall angle adjustment of the luminaire to adapt to the lighting needs of different installation scenarios. The control module is fixed to the lampshade via an independent mounting bracket 600, spatially separated from the heat dissipation component to prevent heat from affecting the controller 700. All components are centrally assembled via the rectangular mounting plate 410, forming a modular structure that facilitates maintenance and component replacement.

[0056] Compared to existing technologies, current lighting fixtures use a one-piece casting method for their heat sink fins and lampshade, requiring the entire unit to be discarded upon failure, and the number of heat sink components cannot be adjusted according to the lampshade size. This solution, through a detachable heat sink component design, allows for independent replacement of heat sink components, reducing maintenance costs. Simultaneously, the rotatable structure of the connecting bracket 500 overcomes the limitations of traditional fixed-angle lighting fixtures, enhancing applicability. The independent installation design of the control module avoids heat conduction issues between the heat sink area and the controller 700, improving system reliability and enabling separate assembly of the heat sink component and lampshade, solving the waste problem caused by the one-piece molding of traditional structures. The modular design allows for flexible addition or reduction of the number of heat sink components according to the lampshade size, improving the ability to adapt to different specifications of lighting fixtures. The adjustable characteristics of the connecting bracket 500 allow the lighting fixture to adapt to various installation angle requirements, expanding application scenarios. The independent installation structure of the control module effectively isolates the heat sink area from electronic components, extending the lifespan of the controller 700.
