Description

Technical Field

[0001] This invention belongs to the field of floor lamp technology, specifically relating to a backlit floor lamp. Background Technology

[0002] High-power floor lamps are typically used in outdoor gardens, courtyard landscapes, or large indoor spaces as accent lighting or decorative accents. To meet requirements for light intensity and visual stability, most existing high-power floor lamps employ a one-piece welded or large fastener-connected, non-removable structure. While this one-piece design ensures overall structural stability, it also introduces significant technical drawbacks: First, due to the lamp's height and size, it cannot be disassembled and repackaged at the factory, requiring custom-made large boxes and substantial cushioning materials, resulting in high packaging costs. Second, the non-removable structure occupies a large amount of space during warehousing and transportation, severely limiting the number of products a single logistics pallet can hold, significantly reducing the loading rate of a single shipment. This not only significantly increases logistics costs but also raises the risk of damage during handling, and is extremely inconvenient for users to bring in and install. Therefore, the existing structural design of high-power floor lamps suffers from high costs and low efficiency in packaging, warehousing, transportation, and installation, urgently requiring optimization and improvement. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a backlit floor lamp that is easy to package and transport and easy for users to assemble.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The backlit floor lamp includes a heat sink, a light-emitting component, a ring-shaped base, a floating base cover, and a lamp holder.

[0005] The heat sink includes a main heat sink and an annular heat sink connected to the periphery of the main heat sink. An air outlet is provided between the main heat sink and the annular heat sink. The main heat sink has a light-emitting panel mounting area with a top opening, and the annular heat sink has a light strip mounting area with a bottom opening in the shape of a ring. A socket is connected to the bottom center of the heat sink. The bottom of the main heat sink has several radially arranged heat dissipation fins. The bottom edge of the heat dissipation fins extends obliquely upward in the radial direction. Adjacent heat dissipation fins form a heat dissipation channel with a bottom opening and the outer end connected to the lower side of the air outlet.

[0006] The light-emitting component includes a high-power main light-emitting board and a ring-shaped light strip. The high-power main light-emitting board is placed in the light-emitting board mounting area. A light-transmitting plate located on the upper side of the high-power main light-emitting board is detachably installed in the light-emitting board mounting area. The ring-shaped light strip is installed in the light strip mounting area. A ring-shaped light-transmitting component is provided on the lower side of the light strip mounting area.

[0007] The annular bottom cover includes a hollow cone-shaped cover. The cover has an air guide edge extending inward from the lower end and a support edge extending upward from the upper end. The inner side of the annular bottom cover is connected to the bottom of the main heat sink through a connecting structure, so that the annular light-transmitting element is sandwiched between the support edge and the lower end of the annular heat sink to form a fixed position.

[0008] The floating bottom cover is in the shape of an inverted cone and has a cover cavity with an upper opening that fits the bottom surface of the heat dissipation fins. The floating bottom cover has a first clearance hole in the middle. The lower outer periphery of the socket has a snap-fit ​​edge extending obliquely upward. The cover cavity has several snap-fit ​​parts located outside the first clearance hole. The floating bottom cover is fastened to the bottom of the air guide edge of the main heat dissipation body and the annular bottom cover by snap-fit ​​parts and snap-fit ​​edges. The cover cavity and the air guide edge form a heat dissipation channel and the first air intake channel on the outside. The first clearance hole of the floating bottom cover and the snap-fit ​​edge form a heat dissipation channel and the second air intake channel on the outside.

[0009] The lamp holder includes a lamp post, the upper end of which is assembled into the socket hole at the bottom of the socket base via a snap-fit ​​structure and a first clearance hole.

[0010] Compared with existing technologies, the backlit floor lamp of this invention achieves a detachable structure while ensuring the heat dissipation performance of high-power lighting through a synergistic design of modular structure and airflow guidance. This significantly reduces packaging, transportation, and installation costs. The heat dissipation frame, with its split layout of the main heat sink and the annular heat sink, combined with radial heat dissipation fins and heat dissipation channels, and the first and second air inlet ducts formed between the inverted conical cover cavity of the suspended bottom cover and the air guide edge, constructs a convective heat dissipation path from the bottom double-sided air intake, guided by the heat dissipation fins, and discharged from the air outlet. While ensuring the heat dissipation requirements of high-power light sources, the heat dissipation frame, the annular bottom cover, the suspended bottom cover, and the lamp holder are all assembled with detachable snap-fit ​​or connecting structures. This allows the product to be disassembled into multiple modular components for flat packaging, greatly reducing the packaging volume, reducing the amount of cushioning material used, effectively reducing the transportation space occupied by a single pallet and logistics costs, while avoiding the inconvenience and damage risk of transporting the whole lamp. Moreover, users can simply snap it together to complete the assembly, taking into account both the stability of use and the convenience of disassembly and assembly.

[0011] Furthermore, the air guide edge is provided with a first air inlet for connecting the heat dissipation channel. The first air inlet is located within the first air intake duct, and the floating bottom cover covers the bottom of the first air inlet. With this configuration, by setting the first air inlet on the air guide edge within the first air intake duct and having the floating bottom cover cover the bottom of the first air inlet, this structure achieves refined adjustment of air intake volume and optimized dust and water resistance while maintaining the original bottom double-sided air intake path. The first air inlet, as a supplementary air intake for the heat dissipation channel, can increase the cross-sectional area of ​​airflow entering the heat dissipation fins, further improving the convective heat dissipation efficiency and meeting the heat dissipation requirements of high-power light sources under high load conditions. At the same time, the covering effect of the floating bottom cover on the bottom of the first air inlet forms a concealed air intake structure, effectively preventing foreign objects, insects, and rainwater from splashing directly into the heat dissipation channel from the bottom. This improves the safety and environmental adaptability for outdoor use while ensuring heat dissipation performance. Moreover, this design is entirely based on the existing component structure and does not require the addition of additional parts, thus balancing the improvement of heat dissipation efficiency with the saving of protection costs.

[0012] Furthermore, the bottom of the main heat sink is provided with an assembly hole located at the center and several connecting posts located outside the assembly hole. The socket is connected to the connecting posts and assembled in the assembly hole via a connector. A fastening kit is assembled at the inner end of the socket hole of the socket. The inner wall of the socket is provided with a first elastic arm with a free lower end, and the inner wall of the fastening kit is provided with a second elastic arm with a free lower end. The snap-fit ​​structure includes a first snap protrusion located at the lower inner end of the first elastic arm, a second snap protrusion located at the lower outer end of the second elastic arm, and a first snap hole and a second snap hole located at the upper end of the lamp post. The lamp post assembly is a hollow structure. When the lamp post is installed relative to the socket, the second snap protrusion snaps into the second snap hole from the inside, and the first snap protrusion snaps into the first snap hole from the outside. With this configuration, the socket can be detachably installed by providing an assembly hole and connecting posts at the bottom of the main heat sink, and a fastening kit with a first elastic arm is integrated and assembled in the socket hole of the socket. The kit utilizes a double-locking structure formed by the first latching protrusion at the lower inner end of the first spring arm, the second latching protrusion at the lower outer end of the second spring arm, and the first and second latching holes at the upper end of the lamp post. This design significantly improves the ease of assembly and connection reliability while enabling modular disassembly and assembly of the lamp holder and heat sink. During installation, simply insert the upper end of the lamp post assembly into the socket hole, and the first and second spring arms will automatically engage the first and second latching protrusions into the corresponding latching holes from the outside and inside respectively through elastic deformation, forming a stable connection with bidirectional interlocking. This ensures the lamp post's tensile and torsional strength when bearing the weight of a high-power lamp head, and allows for quick assembly or disassembly without the need for tools. At the same time, the cooperation between the hollow lamp post and the fastening kit avoids exposed fasteners, maintaining the integrity of the product's appearance. Furthermore, the fastening structure is completely built into the socket hole, effectively reducing the transportation volume during disassembly and packaging, further reducing logistics costs.

[0013] Furthermore, it also includes a pressure seat and a pressure cover. The pressure seat has several connecting posts at the bottom and a pressing edge at the outer periphery, and a snap-fit ​​hole in the middle of the pressure seat; the pressure cover has several snap-fit ​​pieces arranged in a ring extending from the bottom, and the snap-fit ​​pieces are used to snap with the snap-fit ​​hole; the high-power main light-emitting board is connected to the light-emitting board mounting area through connecting pieces, and the high-power main light-emitting board has a second clearance hole in the middle of the middle. The pressure seat is connected to the top of the main heat sink through the connecting posts at the bottom passing through the second clearance hole, so that the high-power main light-emitting board is pressed against the pressing edge. The inner periphery of the light-emitting board mounting area has a first step, and the outer periphery of the light-transmitting plate is installed on the first step. The middle of the light-transmitting plate has a third clearance hole corresponding to the snap-fit ​​hole. The inner diameter of the third clearance hole is smaller than the outer diameter of the pressure cover and the pressure seat. The bottom of the pressure cover is snapped with the snap-fit ​​hole through the third clearance hole by several snap-fit ​​pieces, thereby pressing the light-transmitting plate between the pressure seat and the pressure cover. This design, through the cooperation of the pressure seat and the pressure cover, achieves a dual detachable and stable installation of the high-power main light-emitting board and the light-transmitting plate: the pressure seat is fixed to the top of the main heat sink via the connecting column, which not only presses and positions the main light-emitting board, but also clamps and fixes the light-transmitting plate between the pressure seat and the pressure cover through the snap-fit ​​connection between the pressure cover and the pressure seat. At the same time, the inner diameter of the third clearance hole of the light-transmitting plate is smaller than the outer diameter of the pressure seat and the pressure cover, ensuring effective circumferential limiting of the light-transmitting plate. This structure not only ensures the tightness of the heat dissipation contact of the main light-emitting board and the flatness of the light-transmitting plate installation, but also allows the light-transmitting plate to be disassembled and assembled without tools, which can be completed by snap-fit ​​operation, facilitating subsequent maintenance or replacement. Moreover, all fixing structures are integrated within the light-emitting board installation area, maintaining the simplicity of the product appearance.

[0014] Furthermore, it also includes an annular diffuser plate. The bottom of the annular heat sink has second steps on both sides of the light strip mounting area. The annular light strip is installed on top of the light strip mounting area, and the annular diffuser plate is placed on the second steps and supported on the top of the annular light-transmitting element. With this arrangement, by setting second steps on both sides of the light strip mounting area at the bottom of the annular heat sink, and placing the annular diffuser plate on the second steps to support the annular light-transmitting element, this structure achieves uniform diffusion of light emitted from the annular light strip and modular assembly: the annular diffuser plate can transform the point light source of the annular light strip into a soft annular surface light source, avoiding glare and improving lighting comfort; at the same time, the second steps form precise radial and axial positioning for the annular diffuser plate, ensuring that it fits tightly with the annular light-transmitting element, and both are detachable for easy cleaning or replacement, further enhancing the modular assembly and disassembly advantages of the product while ensuring optical performance.

[0015] Furthermore, the lamp post assembly includes an upper lamp post and a lower lamp post arranged vertically. A first electrical connector is provided in the upper lamp post hole at the lower end of the upper lamp post. This first electrical connector is connected to the light-emitting component via a power supply line. A control switch for controlling the on / off state of the power supply line is provided on the outside of the upper lamp post. A second electrical connector connected to the power supply line is provided at the upper end of the lower lamp post. The upper and lower lamp posts are assembled so that the first and second electrical connectors form a power-conducting connection. This arrangement, by setting the lamp post as a separate structure with upper and lower lamp posts and integrating them at their respective electrical connector ends, achieves a seamless connection. The first and second power connectors are equipped with control switches on the outside of the upper light pole. This design, while enabling modular assembly and disassembly of the light pole, further optimizes the convenience and safety of electrical connections: during the assembly of the upper and lower light poles, the first and second power connectors automatically form a power-on connection, eliminating the need for additional wiring or connection operations. This simplifies the installation process and avoids the safety hazards of exposed wiring. The control switch is directly located on the outside of the upper light pole for easy user operation, and the split light pole structure further reduces the packaging volume. While ensuring reliable electrical performance, it also fully considers the convenience of transportation, installation, and use.

[0016] Furthermore, the inner side of the upper lamp post hole is provided with a positioning groove, and the first power connector is provided with locking blocks on both sides. When the first power connector is installed opposite to the upper lamp post hole, it is fixed by locking the locking blocks into the positioning groove. The second power connector is connected to the upper end of the lower lamp post through a connector. The outer side of the lower lamp post is provided with a locking groove, and the outer side of the upper lamp post is provided with a screw hole communicating with its inner side. The screw hole is located below the first power connector. When the second power connector is inserted into the upper lamp post hole, it is connected to the locking groove by a nut screw passing through the screw hole, thus achieving a fixed connection between the upper and lower lamp posts. With this arrangement, by providing a positioning groove in the upper lamp post hole and the first power connector... The locking mechanism allows for quick, tool-free installation and axial positioning of the first electrical connector, ensuring accurate alignment of the terminals. Simultaneously, the second electrical connector is fixed to the upper end of the lower lamp post via a connector and features a locking groove on its outer side. When the upper and lower lamp posts are connected, simply screw in the mate screw through the screw hole of the upper lamp post and into the locking groove to simultaneously achieve axial locking of the upper and lower lamp posts and circumferential and axial positioning of the second electrical connector. This structure integrates electrical connection and mechanical fixation, ensuring the stability of the electrical connection and preventing poor contact due to rotation or loosening. It also further simplifies the assembly process. Furthermore, the mate screw is a concealed design, maintaining the integrity of the lamp post assembly's appearance while ensuring convenient disassembly and assembly.

[0017] Furthermore, it also includes a power drive device, which comprises a bracket and a circuit board and transformer mounted on the bracket. The upper end of the bracket has deformable and swingable abutment plates on both sides, and the lower end of the lower lamp post has a tapered mounting hole. After the circuit board and transformer are inserted into the tapered mounting hole along with the bracket and are in relative position, they are laterally positioned by the deformable and swingable abutment plates on both sides conforming to the inner wall of the tapered mounting hole. Through this arrangement, by integrating the power drive device onto the bracket and utilizing the deformable and swingable abutment plates on both sides of the bracket to elastically conform to the inner wall of the tapered mounting hole at the lower end of the lower lamp post, this structure achieves… The power drive module features adaptive and rapid installation at the bottom of the light pole: during installation, simply push the bracket into the tapered mounting hole. The abutment piece is compressed by the tapered hole wall, causing elastic deformation and automatically rebounding to fit the inner wall, forming a stable lateral positioning. This effectively prevents the drive device from shaking or shifting without the need for additional fasteners, simplifying the assembly process and improving production assembly efficiency. At the same time, the fit between the tapered hole and the elastic abutment piece can accommodate dimensional tolerances within a certain range, reducing the requirements for machining accuracy. Furthermore, the power drive device is built into the bottom of the light pole assembly, further optimizing space utilization while ensuring electrical safety.

[0018] Furthermore, a connecting ring is provided on the inner side of the lower end of the tapered mounting hole, and connecting edges extending horizontally on both sides of the inner circumference of the connecting ring are respectively located on the upper side. The lower end of the bracket is connected to the connecting edges through a connector. With this configuration, by providing a connecting ring with a horizontal connecting edge on the inner side of the lower end of the tapered mounting hole, and fixing the lower end of the bracket to the connecting edge through the connector, this structure achieves rapid installation and precise alignment of the power drive device based on the lateral positioning of the abutment piece: the connecting ring provides a clear axial installation reference for the bracket, ensuring that the circuit board and transformer can accurately reach the predetermined position. At the same time, fixing the lower end of the bracket to the connecting edge through the connector avoids shaking or offset after installation, further improving the convenience and reliability of the assembly operation; the design of the horizontal connecting edge facilitates tool or manual operation, effectively simplifying the assembly process, and the fixing structure is completely built into the tapered mounting hole, maintaining the neat appearance of the bottom of the lamp post while ensuring assembly efficiency.

[0019] Furthermore, the lamp holder also includes a base cover, which is connected to the connecting ring via a connector to cover the lower opening of the conical mounting hole. This configuration, with a connecting ring featuring a horizontal connecting edge on the inner side of the lower end of the conical mounting hole, and the lower end of the bracket fixed to the connecting edge via the connector, achieves rapid installation and precise alignment of the power drive device based on the lateral positioning of the abutment piece. The connecting ring provides a clear axial installation reference for the bracket, ensuring that the circuit board and transformer can accurately reach the predetermined position. Simultaneously, fixing the lower end of the bracket to the connecting edge via the connector prevents shaking or offset after installation, further improving the convenience and reliability of the assembly operation. The design of the horizontal connecting edge facilitates tool or manual operation, effectively simplifying the assembly process. Moreover, this fixing structure is completely built into the conical mounting hole, maintaining a neat appearance at the bottom of the lamp post while ensuring assembly efficiency.

In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and are not intended to 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 the present invention.

[0034] See Figures 1 to 12 The backlit floor lamp of the present invention includes a heat sink 1, a light-emitting component 2, an annular bottom cover 3, a suspended bottom cover 4, and a lamp holder 5.

[0035] The heat sink 1 includes a main heat sink 11 and an annular heat sink 12 connected to the outer periphery of the main heat sink 11. An air outlet 119 is provided between the main heat sink 11 and the annular heat sink 12. The main heat sink 11 has a light-emitting panel mounting area 141 with a top opening. The annular heat sink 12 has a light strip mounting area 142 with a bottom opening in the shape of a ring. A socket 6 is connected to the bottom center of the heat sink 1. The bottom of the main heat sink 11 is provided with a number of radially arranged heat dissipation fins 16. The bottom edge of the heat dissipation fins 16 extends obliquely upward in the radial direction. A heat dissipation channel with a bottom opening and an outer end connected to the lower side of the air outlet 119 is formed between adjacent heat dissipation fins 16.

[0036] The light-emitting component 2 includes a high-power main light-emitting board 21 and an annular light strip 22. The high-power main light-emitting board 21 has a power of 100W to 300W or more. The high-power main light-emitting board 21 is placed in the light-emitting board mounting area 141. A light-transmitting plate 151 located on the upper side of the high-power main light-emitting board 21 is detachably installed in the light-emitting board mounting area 141. The annular light strip 22 is installed in the light strip mounting area 142. An annular light-transmitting element 159 is provided on the lower side of the light strip mounting area 142. The annular light-transmitting element 159 extends radially outward from the outer side of the annular heat sink 12.

[0037] The annular bottom cover 3 includes a hollow cone-shaped cover 31. The inner side of the cover is used to fit against the bottom periphery of the heat sink 1. The cover 31 is provided with an air guide edge 32 extending inward from the lower end and a support edge 33 extending upward from the upper end. The inner side of the annular bottom cover 3 is connected to the bottom of the main heat sink 11 through a connecting structure, so that the annular light-transmitting element 159 is clamped between the support edge 33 and the lower end of the annular heat sink 12 to form a fixed position.

[0038] The floating bottom cover 4 is in the shape of an inverted cone and has a cover cavity with an upper opening that fits the bottom surface of the heat dissipation fins 16. The cover cavity is used to fit against the inner side of the bottom of the heat dissipation bracket 1 and to cover the central hole at the bottom of the annular bottom cover 3. The floating bottom cover 4 has a first clearance hole 41 in the middle. The lower outer periphery of the socket 6 has a snap-fit ​​edge 66 extending obliquely upward. The cover cavity has several snap-fit ​​pieces 661 located outside the first clearance hole 41. The floating bottom cover 4 is fastened to the bottom of the air guide edge 32 of the main heat dissipation body 11 and the annular bottom cover 3 by snap-fit ​​pieces 661 and snap-fit ​​edge 66. The cover cavity and the air guide edge 32 form a heat dissipation channel and the first air intake channel 42 on the outside. The first clearance hole 41 of the floating bottom cover 4 and the snap-fit ​​edge 66 form a heat dissipation channel and the second air intake channel 43 on the outside.

[0039] The lamp holder 5 includes a lamp post, the upper end of which is assembled into the socket hole at the bottom of the socket 6 through a snap-fit ​​structure via a first clearance hole 41.

[0040] Compared with existing technologies, the backlit floor lamp of the present invention, through the coordinated design of modular structure and airflow guidance, achieves a detachable structure while ensuring the heat dissipation performance of high-power lighting, significantly reducing packaging, transportation and installation costs: The heat dissipation frame 1, through the split layout of the main heat dissipation body 11 and the annular heat dissipation body 12, combined with the radial heat dissipation fins 16 and heat dissipation channels, and combined with the first air inlet channel 42 and the second air inlet channel 43 formed between the inverted conical cover cavity of the suspended bottom cover 4 and the air guide edge 32, constructs a system in which air enters from both sides of the bottom, is guided by the heat dissipation fins 16 and exits from the bottom. The convection cooling path of the air outlet 119 ensures the heat dissipation requirements of high-power light sources. The heat sink 1, the ring-shaped bottom cover 3, the floating bottom cover 4, and the lamp holder 5 are all assembled with detachable snap-fit ​​or connecting structures. This allows the product to be disassembled into multiple modular parts for flat packaging, which greatly reduces the packaging volume, reduces the amount of cushioning material used, effectively reduces the transportation space occupied by a single pallet and logistics costs, and avoids the inconvenience and risk of damage when handling the whole lamp. Moreover, users can simply snap it together to complete the assembly, which takes into account both the stability of use and the convenience of disassembly and assembly.

[0041] See Figures 2 to 7 In one embodiment, the air guide 32 is provided with a first air inlet 34 for connecting to the heat dissipation channel. The first air inlet 34 is located within the first air intake duct 42, and the floating bottom cover 4 covers the bottom of the first air inlet 34. With this arrangement, by providing a first air inlet 34 located within the first air intake duct 42 on the air guide 32, and having the floating bottom cover 4 cover the bottom of the first air inlet 34, this structure achieves refined adjustment of the air intake volume and optimized dust and water resistance while maintaining the original bottom double-sided air intake path. The first air inlet 34 serves as a heat dissipation channel... The supplementary air inlet of the hot channel increases the cross-sectional area of ​​the airflow entering the heat dissipation fins 16, further improving the convective heat dissipation efficiency and meeting the heat dissipation requirements of high-power light sources under high load conditions. At the same time, the suspended bottom cover 4 covers the bottom of the first air inlet 34 to form a concealed air intake structure, effectively preventing foreign objects, insects and rainwater from splashing directly into the heat dissipation channel from the bottom. While ensuring heat dissipation performance, it improves the safety and environmental adaptability for outdoor use. Moreover, this design is entirely based on the existing component structure and does not require the addition of extra parts, thus balancing the improvement of heat dissipation efficiency with the saving of protection costs.

[0042] See Figures 2 to 7In one embodiment, the main heat sink 11 has a centrally located mounting hole 110 at its bottom and several connecting posts 100 located outside the mounting hole 110. The socket 6 is connected to the connecting posts 100 and mounted in the mounting hole 110 via a connector. Inside, the connector is preferably a screw; the inner end of the socket hole of the socket 6 is equipped with a fastening kit 61, the inner wall of the socket hole is provided with a first spring arm 62 with a free lower end, the inner wall of the fastening kit 61 is provided with a second spring arm 611 with a free lower end, the snap-fit ​​structure includes a first snap protrusion 63 at the lower inner end of the first spring arm 62, a second snap protrusion 612 at the lower outer end of the second spring arm 611, and a first snap hole 53 and a second snap hole 54 at the upper end of the lamp post, the lamp post assembly 50 is a hollow structure, when the lamp post is installed in place relative to the socket 6, the second snap protrusion 612 snaps into the second snap hole 54 from the inside, and the first snap protrusion 63 snaps into the first snap hole 53 from the outside; with this arrangement, by providing an assembly hole 110 at the bottom of the main heat sink 11 The connecting post 100 is detachably mounted with the socket 6, and a fastening kit 61 with a first spring arm 62 is integrated into the socket hole of the socket 6. Simultaneously, the first latching protrusion 63 at the lower inner end of the first spring arm 62 and the second latching protrusion 612 at the lower outer end of the second spring arm 611 form a double-locking structure with the first latching hole 53 and the second latching hole 54 at the upper end of the lamp post. This design significantly improves the ease of assembly and connection reliability while enabling modular disassembly and assembly of the lamp holder 5 and the heat sink 1: during installation, only the upper end of the lamp post assembly 50 needs to be inserted into the socket hole, and the first spring arm 62 and... The second spring arm 611 can automatically engage the first latch 63 and the second latch 612 from the outside and inside respectively through elastic deformation, forming a stable connection with bidirectional interlocking. This ensures the tensile and torsional strength of the lamp post when bearing the weight of a high-power lamp head, and allows for quick assembly or disassembly without the need for tools. At the same time, the cooperation between the hollow lamp post and the fastening kit 61 avoids exposed fasteners, maintaining the integrity of the product's appearance. Furthermore, the fastening structure is completely built into the socket hole, effectively reducing the transportation volume during disassembly and packaging, and further reducing logistics costs.

[0043] See Figures 2 to 7In one embodiment, the main heat sink 11 and the annular heat sink 12 are integrally formed; the heat sink frame 1 is made of metal. This arrangement ensures that there are no connection gaps between the main heat sink 11 and the annular heat sink 12, while significantly improving the heat conduction efficiency. This allows the heat generated by the main light-emitting plate 21 to be quickly transferred from the main heat sink 11 to the annular heat sink 12 and then quickly discharged through the heat dissipation channel and the air outlet 119, effectively enhancing the overall heat dissipation performance. The integrally formed structure also avoids the problems of loose connections or contact thermal resistance that may exist in the split design, further improving the structural stability and reliability of the lamp body under high power and long-term operation. The selection of metal materials ensures excellent heat dissipation performance while also providing sufficient mechanical strength for the lamp body, ensuring the assembly accuracy and long-term durability of each snap-fit ​​structure.

[0044] See Figures 2 to 7In one embodiment, the system further includes a pressure seat 13 and a pressure cover 14. The pressure seat 13 has several connecting posts 100 at its bottom and a clamping flange 131 at its outer periphery. A snap-fit ​​hole 132 is provided in the center of the pressure seat 13. The pressure cover 14 is a hollow, frustum-shaped structure with an open bottom. Several ring-arranged fasteners 141 extend from the bottom and are used to engage with the snap-fit ​​hole 132. The high-power main light-emitting board 21 is connected to the light-emitting board mounting area 141 via a connector, preferably a screw. The high-power main light-emitting board 21 has a second clearance hole 210 in its center with an inner diameter smaller than the outer diameter of the pressure seat 13. The pressure seat 13 connects to the main light-emitting board 21 through the connecting posts 100 at its bottom passing through the second clearance hole 210. The top of the main heat sink 11 is connected, so that the high-power main light-emitting plate 21 is pressed against the clamping stop 131. The inner circumference of the light-emitting plate mounting area 141 is provided with a first step portion 143. The outer circumference of the light-transmitting plate 151 is installed on the first step portion 143. The middle part of the light-transmitting plate 151 is provided with a third clearance hole 153 corresponding to the snap-fit ​​hole 132. The inner diameter of the third clearance hole 153 is smaller than the outer diameter of the pressure cover 14 and the pressure seat 13. The bottom of the pressure cover 14 is fastened to the snap-fit ​​hole 132 through several of the snap fasteners 141 passing through the third clearance hole 153, thereby pressing the light-transmitting plate 151 between the pressure seat 13 and the pressure cover 14. With this configuration, the combination of the pressure base 13 and the pressure cover 14 enables a dual detachable and stable installation of the high-power main light-emitting board 21 and the light-transmitting plate 151. The pressure base 13 is fixed to the top of the main heat sink 11 via the connecting column 100, which not only presses and positions the main light-emitting board 21, but also clamps and fixes the light-transmitting plate 151 between the pressure base 13 and the pressure cover 14 through the snap-fit ​​connection between the pressure cover 14 and the pressure base 13. At the same time, the inner diameter of the third clearance hole 153 of the light-transmitting plate 151 is smaller than the outer diameter of the pressure base 13 and the pressure cover 14, ensuring effective circumferential limiting of the light-transmitting plate 151. This structure not only ensures the tightness of the heat dissipation contact of the main light-emitting board 21 and the flatness of the installation of the light-transmitting plate 151, but also allows the installation and removal of the light-transmitting plate 151 without the need for tools, which can be completed by snap-fit ​​operation, facilitating subsequent maintenance or replacement. Moreover, all fixing structures are integrated within the light-emitting board installation area 141, maintaining the simplicity of the product appearance.

[0045] See Figures 2 to 7In one embodiment, the annular light strip 22 is fixed to the top wall of the light strip mounting area 142 by adhesive bonding; it also includes an annular diffuser plate 152. The bottom of the annular heat sink 12 is provided with second step portions 144 on both sides of the light strip mounting area 142. The annular light strip 22 is installed on the top of the light strip mounting area 142, and the annular diffuser plate 152 is placed on the second step portions 144 and supported on the top of the annular light-transmitting element 159. With this arrangement, by providing second step portions 144 on both sides of the light strip mounting area 142 at the bottom of the annular heat sink 12, the annular diffuser plate is... The diffuser plate 152 is placed on the second step 144 and supports the annular light-transmitting element 159. This structure realizes the uniform diffusion of light emitted from the annular light strip 22 and modular assembly: the annular diffuser plate 152 can transform the point light source of the annular light strip 22 into a soft annular surface light source, avoiding glare and improving lighting comfort; at the same time, the second step 144 forms a precise radial and axial positioning for the annular diffuser plate 152, ensuring that it fits tightly with the annular light-transmitting element 159, and both are detachable, which is convenient for cleaning or replacement. While ensuring the optical effect, it further enhances the modular disassembly and assembly advantages of the product.

[0046] See Figure 10 and Figure 11 In one embodiment, the lamp post assembly 50 includes an upper lamp post 51 and a lower lamp post 52 arranged vertically. A first electrical connector 511 is provided in the upper lamp post hole 51 at the lower end of the upper lamp post 51. The first electrical connector 511 is connected to the light-emitting component 2 via a power supply line. A control switch 53 for controlling the on / off state of the power supply line is provided on the outside of the upper lamp post 51. A second electrical connector 512 connected to the power supply line is provided at the upper end of the lower lamp post 52. When the upper lamp post 51 and the lower lamp post 52 are assembled, the first electrical connector 511 and the second electrical connector 512 form a power-conducting connection. This arrangement achieves a split structure of the upper lamp post 51 and the lower lamp post 52. The design integrates a first power connector 511 and a second power connector 512 at the power connection ends of both lamp posts 51, and a control switch 53 is installed on the outside of the upper lamp post 51. This design not only enables modular assembly and disassembly of the lamp post, but also further optimizes the convenience and safety of electrical connections: when assembling the upper and lower lamp posts 52, the first power connector 511 and the second power connector 512 automatically form a power-on connection, eliminating the need for additional wiring or connection operations. This simplifies the installation process and avoids the safety hazards of exposed wiring. The control switch 53 is directly located on the outside of the upper lamp post 51 for easy user operation, and the split lamp post structure further reduces the packaging volume. While ensuring reliable electrical performance, it also fully considers the convenience of transportation, installation, and use.

[0047] See Figure 10 and Figure 11In one embodiment, the first power connector 511 is provided with a plurality of power connector pins electrically connected to the power supply line, and the second power connector 512 is provided with a plurality of power connector holes electrically connected to the power supply line, wherein the power connector pins are energized and plugged into the power connector holes one-to-one; or, the first power connector 511 is provided with a plurality of power connector holes electrically connected to the power supply line, and the second power connector 512 is provided with a plurality of power connector pins electrically connected to the power supply line, wherein the power connector pins are energized and plugged into the power connector holes one-to-one.

[0048] See Figure 10 and Figure 11 In one embodiment, the first power connector 511 has a power slot 513 with an open lower end, the inner diameter of which is D-shaped. The shape of the second power connector 512 is adapted to the power slot 513. With this arrangement, the first power connector 511 has a power slot 513 with an open lower end, and the inner diameter of which is D-shaped. The shape of the second power connector 512 is adapted to the D-shaped power slot 513. Through this D-shaped foolproof structure design, the first power connector... While the first connector 511 and the second connector 512 can be quickly and accurately plugged in, the reverse polarity or poor contact caused by incorrect plugging direction is effectively prevented, which significantly improves the reliability and safety of the electrical connection. This structure can achieve precise plugging without the user having to visually identify or adjust the direction, which further simplifies the assembly operation of the upper light pole 51 and the lower light pole 52. Even non-professionals can easily complete the installation, effectively avoiding circuit failures or safety hazards caused by misoperation, and taking into account both assembly convenience and electrical protection requirements.

[0049] See Figure 10 and Figure 11In one embodiment, the upper lamp post hole 51 has a circumferential positioning groove 541 on its inner side. The first power connector 511 has locking blocks 514 on both sides. When the first power connector 511 is installed opposite to the upper lamp post hole 51, it is fixed by being engaged in the positioning groove 541 by the locking blocks 514. The second power connector 512 is connected to the upper end of the lower lamp post 52 via a connector, preferably a screw. The lower lamp post 52 has a circumferential locking groove 515 on its outer side. The upper lamp post 51 has a screw hole 516 on its outer side, communicating with its inner side. The screw hole 516 is located below the first power connector 511. When the second power connector 512 is inserted into the upper lamp post hole 51, it is connected to the locking groove 515 by a nut screw 517 passing through the screw hole 516, thus achieving a fixed connection between the upper lamp post 51 and the lower lamp post 52. With this arrangement, the upper lamp post 51 and the lower lamp post 52 are fixedly connected. A positioning groove 541 is provided in the lamp post hole 51 to engage with the locking block 514 of the first electrical connector 511, enabling quick tool-free installation and axial positioning of the first electrical connector 511 and ensuring accurate alignment of the electrical terminals. At the same time, the second electrical connector 512 is fixed to the upper end of the lower lamp post 52 by a connector and has a locking groove 515 on its outer side. When the upper and lower lamp posts 52 are connected, only the locating screw 517 needs to be screwed in through the screw hole 516 of the upper lamp post 51 and locked into the locking groove 515 to simultaneously achieve axial locking of the upper and lower lamp posts 52 and circumferential and axial positioning of the second electrical connector 512. This structure combines electrical connection and mechanical fixation into one, which not only ensures the stability of the electrical connection and avoids poor contact due to rotation or loosening, but also further simplifies the assembly steps. Moreover, the locating screw 517 is a hidden design, which ensures convenient disassembly and assembly while maintaining the integrity of the appearance of the lamp post assembly 50.

[0050] See Figure 10 and Figure 11In one embodiment, the upper end of the lower lamp post 52 is connected to a mounting base 55, and a locking groove 515 is provided on the mounting base 55. The mounting base 55 has a hollow insertion hole 551, and a retaining groove 552 is provided inside the insertion hole 551. The lower end of the second power connector 512 is provided with several retaining spring clips 518. When the lower end of the second power connector 512 is inserted into the insertion hole 551, the retaining spring clips 518 engage with the retaining groove 552 to achieve assembly and fixation. With this arrangement, the upper end of the lower lamp post 52 is provided with a mounting base 55, the hollow insertion hole 551 of the mounting base 55 is provided with a retaining groove 552, and the lower end of the second power connector 512 is provided with several retaining spring clips 518. When the second power connector 512 is inserted into the insertion hole 551, the retaining spring clips 518 engage with the retaining groove 552 to achieve assembly and fixation. When 51 is in position, the snap-fit ​​spring clip 518 automatically snaps into the snap-fit ​​groove 552, realizing quick tool-free assembly between the second electrical connector 512 and the mounting base 55. This snap-fit ​​structure ensures the electrical module is firmly fixed while completing the installation without screws or other fasteners, significantly improving production efficiency. The snap-fit ​​spring clip 518 is distributed at multiple points along the circumference, forming a circumferentially uniform force structure with the annular snap-fit ​​groove 552, effectively preventing the second electrical connector 512 from tilting or loosening during insertion, removal or use, ensuring positioning accuracy and electrical contact reliability when it is inserted with the first electrical connector 511. This detachable design also facilitates the replacement of the second electrical connector 512 separately during later maintenance without disassembling the entire lamp post assembly 50, reducing maintenance costs and operational difficulty.

[0051] See Figure 12In one embodiment, a power drive device 7 is further included. The power drive device 7 includes a bracket 71 and a circuit board 72 and a transformer 73 mounted on the bracket 71. The transformer 73 has a power line on one side and a power line 731 extending outward from the outlet of the lower lamp post 52 on the other side. The upper end of the bracket 71 is provided with abutment pieces 74 that can deform and swing around a horizontal axis on both sides. The lower end of the lower lamp post 52 has a tapered mounting hole 520. After the circuit board 72 and the transformer 73 are inserted into the tapered mounting hole 520 and positioned relative to each other as the bracket 71 extends into the tapered mounting hole 520, they are laterally positioned by the deformation and swing of the abutment pieces 74 on both sides against the inner wall of the tapered mounting hole 520. With this arrangement, by integrating the power drive device 7 onto the bracket 71 and utilizing the two sides of the bracket 71, the power drive device 7 is integrated into the bracket 71 and the power drive device 73 is positioned relative to the lower lamp post 520. The laterally deformable and swingable abutment piece 74 elastically fits against the inner wall of the tapered mounting hole 520 at the lower end of the lower lamp post 52. This structure enables the power drive module to be installed adaptively and quickly at the bottom of the lamp post: during installation, only the bracket 71 needs to be pushed into the tapered mounting hole 520. The abutment piece 74 is squeezed by the tapered hole wall, which causes elastic deformation and automatically rebounds to fit against the inner wall, forming a stable lateral positioning. No additional fasteners are needed to effectively prevent the drive device from shaking or shifting, which simplifies the assembly process and improves production assembly efficiency. At the same time, the fit between the tapered hole and the elastic abutment piece 74 can adapt to a certain range of dimensional tolerances, reducing the requirements for machining accuracy. Furthermore, the power drive device 7 is built into the bottom of the lamp post assembly 50, which further optimizes space utilization while ensuring electrical safety.

[0052] See Figure 12 In one embodiment, a connecting ring 75 is provided on the inner side of the lower end of the tapered mounting hole 520. Connecting edges 751, extending horizontally upwards on both sides of the inner circumference of the connecting ring 75, are provided. The lower end of the bracket 71 is connected to the connecting edges 751 via a connector, preferably a screw. With this arrangement, by providing a connecting ring 75 with a horizontal connecting edge 751 on the inner side of the lower end of the tapered mounting hole 520, and fixing the lower end of the bracket 71 to the connecting edge 751 via a connector, this structure, based on the lateral positioning of the abutment piece 74, realizes the power drive device 7. Rapid installation and precise alignment: The connecting ring 75 provides a clear axial installation reference for the bracket 71, ensuring that the circuit board 72 and transformer 73 can accurately reach the predetermined position. At the same time, the lower end of the bracket 71 is fixed to the connecting edge 751 by the connector, avoiding shaking or offset after installation, and further improving the convenience and reliability of the assembly operation. The design of the horizontal connecting edge 751 facilitates tool or manual operation, effectively simplifying the assembly process. Moreover, the fixing structure is completely built into the tapered mounting hole 520, which maintains the neat appearance of the bottom of the lamp post while ensuring assembly efficiency.

[0053] See Figure 12In one embodiment, the lamp holder 5 further includes a base cover 58, which is connected to the connecting ring 75 via a connector to cover the lower opening of the tapered mounting hole 520. The connector is preferably a screw. With this configuration, by providing a connecting ring 75 with a horizontal connecting edge 751 on the inner side of the lower end of the tapered mounting hole 520, and fixing the lower end of the bracket 71 to the connecting edge 751 via the connector, this structure, based on the lateral positioning of the abutment piece 74, achieves rapid installation and precise alignment of the power drive device 7. The connecting ring 75 provides a clear axial installation reference for the bracket 71, ensuring that the circuit board 72 and the transformer 73 can accurately reach the predetermined position. At the same time, fixing the lower end of the bracket 71 to the connecting edge 751 via the connector avoids shaking or offset after installation, further improving the convenience and reliability of the assembly operation. The design of the horizontal connecting edge 751 facilitates tool or manual operation, effectively simplifying the assembly process. Moreover, the fixing structure is completely built into the tapered mounting hole 520, maintaining the neat appearance of the bottom of the lamp post while ensuring assembly efficiency.

[0054] See Figures 2 to 10In one embodiment, a heat diffusion port 192 is provided on the lower side of the middle portion of the heat dissipation fin 16, dividing the heat dissipation fin 16 into first fins 18 and second fins 162 arranged radially outward. The upper portions of the first fins 18 and second fins 162 are connected as one unit by connecting ribs 191. The height of the first fin 18 is greater than the height of the second fin 162, and the bottom edges of the first fins 18 and second fins 162 extend radially upward. A first radial heat dissipation channel 163 with a bottom opening is formed between adjacent first fins 18, and a bottom opening is formed between adjacent second fins 162, which respectively connect to the first radial heat dissipation channel 163 and the air outlet 119 in the same radial direction. The lower second radial heat dissipation channel 164 and the adjacent heat diffusion port 192 form a circumferential heat dissipation channel 165 that connects each of the first radial heat dissipation channels 163 and the second radial heat dissipation channel 164, so that the first air inlet duct 42 connects the first radial heat dissipation channel 163 and the second radial heat dissipation channel 164 through the circumferential heat dissipation channel 165; the first radial heat dissipation channel 163 and the second radial heat dissipation channel 164 constitute the heat dissipation channel; the inner end of the air guide edge 32 abuts against the outer side of the first fin 18; the air guide edge 32 is provided with a first air inlet 34 for connecting the bottom of the first radial heat dissipation channel 163, and the first air inlet 34 is located inside the first air inlet duct 42.With this configuration, the heat sink 1 includes a main heat sink 11 and an annular heat sink 12, with an air outlet 119 circumferentially arranged between them. The bottom of the main heat sink 11 has first fins 18 and second fins 162 of different heights arranged radially. Adjacent fins form a first radial heat dissipation channel 163, a second radial heat dissipation channel 164, and a connected circumferential heat dissipation channel 165. Combined with the high-power main light-emitting board 21, the light-emitting components 2 of the annular light strip 22, the annular bottom cover 3 with air guide edge 32 and support edge 33, the suspended bottom cover 4 with a cover cavity and a first clearance hole 41, and the lamp holder 5, a three-dimensional multi-level system is constructed. The air circulation path is as follows: Specifically, because the height of the first fin 18 is greater than that of the second fin 162, the air in the adjacent heat source and the corresponding second radial heat dissipation channel 164 of the second fin 162 heats up faster. According to Bernoulli's principle, when airflow forms above the air outlet 119 due to thermal pressure or natural wind, the air pressure in that area decreases, thus creating a negative pressure suction effect in the second radial heat dissipation channel 164. This drives external low-temperature air to be automatically drawn in through the first air inlet 34 on the air guide 32 of the annular bottom cover 3, providing efficient forced convection cooling to the second fin 162. Simultaneously, according to the same principle, external air... The airflow is also introduced into the first radial heat dissipation channel 163 through the first air inlet channel 42 formed between the suspended bottom cover 4 and the air guide 32, and the second air inlet channel 43 formed by the first clearance hole 41 of the suspended bottom cover 4. It flows sequentially over the surfaces of the first fin 18 and the second fin 162, carrying away accumulated heat and further enhancing the heat dissipation effect on the second fin 162 and even the entire heat sink 1. Meanwhile, the circumferential heat dissipation channel 165 utilizes the hot air pressure difference to allow the incoming airflow to quickly and evenly diffuse into each of the first radial heat dissipation channels 163, effectively avoiding local hot spots and ensuring a balanced temperature distribution throughout the entire heat sink 1. This basic... The self-driven air-cooling mechanism, which combines the temperature difference caused by the fin height difference with the Bernoulli effect, can significantly improve air convection efficiency without additional energy consumption. It completely solves the problem of poor heat dissipation performance caused by the sealed or solid structure of high-power floor lamps. It not only greatly reduces the operating temperature of the light source and driving components, suppresses light decay and extends the service life of the entire lamp, but also eliminates safety hazards and the risk of burns. At the same time, the assembly structure of the annular bottom cover 3 and the floating bottom cover 4 achieves efficient heat dissipation airflow while ensuring the integrity, layering and light-transmitting decorative effect of the lamp body appearance, achieving a perfect unity of high performance, high reliability, high safety and artistic beauty.

[0055] See Figures 2 to 10In one embodiment, the air guide 32 is provided with radially arranged air guide ribs 341 on the upper side of the first air inlet 34. The air guide ribs 341 extend into the second radial heat dissipation channel 164. The air guide ribs 341 are respectively connected to the first air inlet 34 and face the second fins 162 on both sides. With this arrangement, the incoming airflow is precisely guided and diverted: when external cold air is drawn in by negative pressure, the air guide ribs 341 not only play a role in structural reinforcement, but more importantly, they can orderly sort the airflow into two streams, which flow along the inner walls of the second radial heat dissipation channel 164 on both sides. This significantly increases the contact area and flow rate between the cooling airflow and the second fins 162 and the channel wall, avoiding disorderly airflow collision or the formation of vortex dead zones, ensuring that every inch of heat dissipation surface can be fully flushed, greatly improving the heat dissipation utilization efficiency of the limited air intake space, and maximizing the efficiency of the Bernoulli effect-induced cooling airflow, further enhancing the directional cooling effect on high heat flux density areas.

[0056] See Figures 2 to 10 In one embodiment, the upper side of the outer end of the second fin 162 is provided with air guide ribs 17 extending from between the main heat sink 11 and the annular heat sink 12 to the upper side of the air outlet 119. The air guide ribs 17 divide the air outlet 119 into several groups, so that the several air outlets 119 correspond one-to-one with the second radial heat dissipation channel 164. This arrangement effectively regulates and accelerates the exhaust path of hot air: when the hot air in the second radial heat dissipation channel 164 is drawn out due to the Bernoulli effect, the air guide ribs 17 not only physically isolate each air outlet 119, preventing adjacent channels from being exhausted, but also provide a safer and more efficient airflow path. The mutual interference and turbulence of the airflow are reduced, but more importantly, the original annular air outlet 119 is divided into independent exhaust units corresponding to each of the second radial heat dissipation channels 164 below. This one-to-one correspondence creates multiple parallel and non-interfering smooth exhaust channels for the hot airflow, greatly reducing exhaust resistance. This allows the high-temperature air in each channel to be directed out of the lamp body with the shortest path and the fastest speed, thereby forming a strong and orderly negative pressure suction zone at the top of the heat dissipation frame 1, further enhancing the intake efficiency of the cold air at the bottom, and qualitatively improving the smoothness and heat dissipation capacity of the entire self-driven air-cooling cycle.

[0057] See Figures 2 to 10In one embodiment, the upper side of the outer end of the second fin 162 is provided with air guide ribs 17 extending from between the main heat sink 11 and the annular heat sink 12 to the upper side of the air outlet 119. The air guide ribs 17 divide the air outlet 119 into several groups, so that the several air outlets 119 correspond one-to-one with the second radial heat dissipation channel 164. This arrangement effectively regulates and accelerates the exhaust path of hot air: when the hot air in the second radial heat dissipation channel 164 is drawn out due to the Bernoulli effect, the air guide ribs 17 not only physically isolate each air outlet 119, preventing adjacent channels from being exhausted, but also provide a safer and more efficient airflow path. The mutual interference and turbulence of the airflow are reduced, but more importantly, the original annular air outlet 119 is divided into independent exhaust units corresponding to each of the second radial heat dissipation channels 164 below. This one-to-one correspondence creates multiple parallel and non-interfering smooth exhaust channels for the hot airflow, greatly reducing exhaust resistance. This allows the high-temperature air in each channel to be directed out of the lamp body with the shortest path and the fastest speed, thereby forming a strong and orderly negative pressure suction zone at the top of the heat dissipation frame 1, further enhancing the intake efficiency of the cold air at the bottom, and qualitatively improving the smoothness and heat dissipation capacity of the entire self-driven air-cooling cycle.

[0058] See Figures 3 to 9 In one embodiment, the annular heat sink 12 has an upwardly extending air outlet baffle 121 on its top outer periphery, forming an air outlet groove 122 with openings on the upper and inner sides at the top of the annular heat sink 12. The inner side of the air outlet groove 122 connects to the air outlet 119, and the air guide ribs 17 extend radially to the inner side of the air outlet groove 122. This arrangement effectively gathers and guides the hot airflow for directional discharge: when hot air flows out through the air outlet 119, the air outlet groove 122 provides a temporary gathering and buffering space, while the air outlet baffle 121 acts as a physical barrier, preventing the exhaust from reaching the outlet. The hot air is disturbed by the external lateral airflow and flows back into the lamp body. It can also guide the hot airflow to be smoothly and directionally discharged along the upper and inner openings of the air outlet 122, thereby creating a stable low-pressure exhaust zone at the top of the heat sink 1. This ensures that the heat is quickly and efficiently discharged into the environment, greatly improving the overall heat dissipation circulation efficiency. It also generates a strong scouring and heat exchange effect on the annular heat sink 12 and the annular light strip 22 at the bottom, thereby efficiently removing the heat accumulated on the annular heat sink 12 and realizing active heat dissipation and cooling of the annular light strip 22.

[0059] See Figures 3 to 9In one embodiment, the air guide ribs 17 extend radially to the inner side of the air outlet slot 122 and form a gap with the air outlet baffle 121. The air outlet slot 122 is provided with an upwardly extending air guide diversion protrusion 173, which is arranged between two adjacent air guide ribs 17. With this arrangement, the hot air gathered in the air outlet slot 122 is finely diverted and guided: the gap between the air guide ribs 17 and the air outlet baffle 121 forms a turning and acceleration space for the airflow, avoiding the airflow from directly hitting the air outlet baffle 121 and causing obstruction; while the air guide diversion protrusion 173 further divides each air outlet slot 122 unit into two sub-channels, so that the hot airflow is orderly diverted and guided to the inner and outer sides of the air outlet baffle 121 for directional discharge. This not only increases the exhaust path, but also prevents the airflow of adjacent air outlets 119 from interfering with each other and forming turbulence, thereby significantly improving the overall exhaust smoothness and heat dissipation efficiency of the air outlet slot 122.

[0060] See Figure 8 and Figure 9 In one embodiment, the bottom of the main heat sink 11 is provided with a plurality of heat dissipation columns 111 extending into the second radial heat dissipation channel 164, and the plurality of heat dissipation columns 111 are arranged in the radial direction. By setting it in this way, the heat exchange area in the channel is effectively increased and the airflow state is disturbed: these heat dissipation columns 111 not only serve as extended heat exchange surfaces, directly increasing the heat exchange area with the cooling air, but more importantly, they form a turbulence structure in the airflow channel, causing the flowing cooling air to generate eddies and turbulence, thereby destroying the laminar boundary layer, significantly improving the convective heat transfer coefficient between the air and the heat dissipation surface, so that each stream of cooling air entering the second radial heat dissipation channel 164 can more fully absorb and carry away heat, further enhancing the directional heat dissipation effect on the high-heat area.

[0061] See Figure 8 and Figure 9 In one embodiment, the first fin 18 includes a long first fin 181 and a short first fin 182. The radial length of the short first fin 182 is shorter than that of the long first fin 181. The short first fin 182 is positioned close to the outer side of the long first fin 181. The short first fin 182 and the long first fin 181 are arranged alternately in the circumferential direction. By designing some fins as short first fins 182 with a shorter radial length and positioning them close to the outer side of the long first fin 181, the space constraints of the annular heat sink 12 and other internal structures are effectively avoided, thereby accommodating a larger number of fin units within the limited circumferential space. At the same time, the alternating arrangement of long and short fins further optimizes the space utilization, allowing more heat exchange surfaces to be densely arranged at the bottom of the heat sink 1, significantly increasing the overall heat dissipation area and laying a structural foundation for efficient heat exchange.

[0062] See Figure 8 and Figure 9 In one embodiment, the heat sink 1 is manufactured as a single piece of metal material. This design ensures that the heat sink 1 has extremely high structural strength and dimensional accuracy, while eliminating the contact thermal resistance between the components. This allows for seamless heat conduction between all heat dissipation units, such as the main heat sink 11, the annular heat sink 12, the heat dissipation fins 16, and the heat dissipation pillars 111. Heat can be rapidly diffused along a continuous metal path to the entire heat sink 1, significantly improving the overall thermal conductivity. Furthermore, the single-piece molding process simplifies the manufacturing process, reduces assembly costs and tolerance accumulation, and ensures product consistency and reliability.

[0063] In one embodiment, the bottom of the heat sink 1 is provided with a plurality of connecting posts 100, and the air guide edge 32 of the annular bottom cover 3 is connected to the plurality of connecting posts 100 by screws, thereby fixing the annular bottom cover 3 to the outer periphery of the bottom of a plurality of heat dissipation fins 16 of the heat sink 1. Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
