Description

Technical Field

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

[0002] High-power floor lamps are widely used in outdoor gardens and courtyards, as well as indoor living rooms and exhibition halls, as accent lighting or artistic decorations due to their excellent lighting effects and decorative functions. Existing high-power floor lamps typically integrate high-power LED chips or high-power light sources into their lighting fixtures to achieve high brightness output.

[0003] However, current high-power floor lamps on the market have significant structural design flaws: most of their lighting fixtures use a solid structure or a completely sealed design. While this structure ensures a certain degree of overall appearance and waterproof / dustproof capability, it severely neglects the lamp's heat dissipation requirements. High-power light sources generate a large amount of heat during operation, and the solid or sealed structure prevents this heat from being effectively conducted to the outside air, easily leading to heat buildup within the cavity.

[0004] Prolonged operation under overheating conditions not only accelerates light decay and significantly shortens the lifespan of the light source, but also affects the stability of electronic components such as the driver power supply, and may even lead to safety hazards such as insulation aging and short circuits. Furthermore, high temperatures can cause the surface temperature of the lamp to become excessively high, increasing the risk of burns. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-power backlit floor lamp with good heat dissipation performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-power backlit floor lamp, comprising a heat sink, light-emitting components, a ring-shaped base, a floating base cover, and a lamp holder.

[0007] A 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 circumferentially 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. Several radially arranged heat dissipation fins are provided circumferentially at the bottom of the main heat sink. The heat dissipation fins include first fins and second fins arranged at intervals along the radial outer side. The height of the first fin is greater than the height of the second fin, and the bottom edges of the first fin and the second fin extend obliquely upward in the radial direction. A first radial heat dissipation channel with a bottom opening is formed between adjacent first fins. A second radial heat dissipation channel with a bottom opening and respectively connected to the first radial heat dissipation channel in the same radial direction and the second radial heat dissipation channel below the air outlet is formed between adjacent second fins. A circumferential heat dissipation channel connecting each first radial heat dissipation channel and the second radial heat dissipation channel is formed between adjacent first fins and second fins.

[0008] The light-emitting component includes a high-power main light-emitting panel and a ring-shaped light strip. The high-power main light-emitting panel is placed in the light-emitting panel mounting area, and the ring-shaped light strip is installed in the light strip mounting area. A ring-shaped light-transmitting element is provided on the lower side of the light strip mounting area.

[0009] The annular bottom cover includes a hollow cone-shaped shell. The shell 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 covered by a connecting structure at the bottom of each second fin of the main heat sink, 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. The air guide edge has several first air inlets for connecting the bottom of each first radial heat dissipation channel.

[0010] The floating bottom cover has a cover cavity with an upper opening that is adapted to the bottom surface of the first fin. The floating bottom cover has a first clearance hole located in the middle. The floating bottom cover is assembled on the bottom of the air guide edge of several first fins and the annular bottom cover. The cover cavity and the air guide edge form a circumferential heat dissipation channel and a first air intake channel on the outside. The first air inlet is located in the first air intake channel. The first clearance hole of the floating bottom cover forms a second air intake channel that connects the first radial heat dissipation channel and the outside.

[0011] The lamp holder includes a lamp pole assembly, 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.

[0012] Compared with existing technologies, the high-power backlit floor lamp of the present invention, by setting the heat dissipation frame to include a main heat dissipation body and an annular heat dissipation body, with an air outlet arranged circumferentially between the two, and first and second fins of different heights radially arranged at the bottom of the main heat dissipation body, forming a first radial heat dissipation channel, a second radial heat dissipation channel, and a connected circumferential heat dissipation channel between adjacent fins, and in conjunction with the high-power main light-emitting panel and the light-emitting components of the annular light strip, the annular bottom cover with air guide edge and support edge, the floating bottom cover with cover cavity and first clearance hole, and the lamp frame assembly, constructs a three-dimensional multi-level air circulation system. The ring path; specifically, because the height of the first fin is greater than that of the second fin, the air in the second radial heat dissipation channel adjacent to the heat source and the corresponding second fin heats up faster. According to Bernoulli's principle, when airflow forms above the air outlet due to thermal pressure or natural wind, the air pressure in that area decreases, thereby generating a negative pressure suction effect in the second radial heat dissipation channel. This drives the external low-temperature air to be automatically drawn in through the first air inlet on the air guide edge of the annular bottom cover, providing efficient forced convection cooling to the second fin. At the same time, according to the same principle, the external airflow also passes through the suspended bottom... The first air intake duct formed between the cover and the air guide edge, and the second air intake duct formed by the first clearance hole of the suspended bottom cover, are orderly introduced into the first radial heat dissipation channel, flowing sequentially over the surfaces of the first and second fins, carrying away accumulated heat and further enhancing the heat dissipation effect on the second fins and even the entire heat sink; while the circumferential heat dissipation channel 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, effectively avoiding local hot spots and ensuring a balanced temperature distribution throughout the heat sink; this temperature difference based on the fin height difference is similar to the Bernoulli effect. The integrated self-driven air-cooling mechanism significantly improves air convection efficiency without additional energy consumption, completely solving the problem of poor heat dissipation 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 life of the entire lamp, but also eliminates safety hazards and the risk of burns. At the same time, the assembly structure of the ring-shaped bottom cover and the floating bottom cover achieves efficient heat dissipation airflow while ensuring the integrity, layering, and light-transmitting decorative effect of the lamp body, achieving a perfect unity of high performance, high reliability, high safety, and artistic beauty.

[0013] Furthermore, the air guide is provided with radially arranged air guide ribs on the upper side of the first air inlet. The air guide ribs extend into the second radial heat dissipation channel, and the first air inlet is located on both sides of the air guide ribs. 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 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 two sides of the second radial heat dissipation channel. This significantly increases the contact area and flow rate between the cooling airflow and the second fins and the channel wall, avoiding disorderly airflow collisions or the formation of vortex dead zones. This ensures that every inch of the heat dissipation surface can be fully flushed, greatly improving the heat dissipation utilization efficiency of the limited air intake space, allowing the Bernoulli effect-induced cooling airflow to exert its maximum efficiency, and further enhancing the directional cooling effect on high heat flux density areas.

[0014] Furthermore, the upper side of the outer end of the second fin is provided with air guide ribs extending from between the main heat sink and the annular heat sink to the upper side of the air outlet. These air guide ribs divide the air outlet into several sections, thus forming a one-to-one correspondence between each air outlet and the second radial heat dissipation channel. This arrangement effectively regulates and accelerates the exhaust path of hot air: when hot air in the second radial heat dissipation channel is drawn out due to the Bernoulli effect, the air guide ribs not only physically isolate each air outlet, preventing mutual interference and turbulence between adjacent channels, but also... More importantly, it divides the original ring-shaped air outlet into independent exhaust units that correspond one-to-one with each of the second radial heat dissipation channels below. This one-to-one correspondence creates multiple parallel and non-interfering smooth exhaust channels for hot airflow, greatly reducing exhaust resistance. This allows the high-temperature air in each channel to be directed out of the lamp body through the shortest path and at the fastest speed, thereby forming a strong and orderly negative pressure suction zone at the top of the heat dissipation frame. This further enhances the intake efficiency of cold air at the bottom, resulting in a qualitative improvement in the smoothness and heat dissipation capacity of the entire self-driven air-cooling cycle.

[0015] Furthermore, the annular heat sink has an upwardly extending air outlet baffle on its top outer periphery, forming an air outlet groove with openings on the upper and inner sides. The inner side of the air outlet groove connects to the air outlet, and the air guide ribs extend radially to the inner side of the air outlet groove. This arrangement effectively gathers and guides the hot airflow for directional discharge. When hot air flows out through the air outlet, the air outlet groove provides a temporary gathering and buffering space, while the air outlet baffle acts as a physical barrier. This prevents the discharged hot air from being disturbed by external lateral airflow and flowing back into the lamp body, and also guides the hot airflow to be smoothly discharged directionally along the upper and inner openings of the air outlet groove. This creates a stable low-pressure exhaust zone on the top of the heat sink, ensuring that heat is quickly and efficiently discharged into the environment, significantly improving the overall heat dissipation circulation efficiency. This generates a strong scouring and heat exchange effect on the annular heat sink and the annular heat sink with the annular light strip at the bottom, effectively removing the heat accumulated on the annular heat sink and achieving active heat dissipation and cooling of the annular light strip.

[0016] Furthermore, the air guide ribs extend radially to the inner side of the air outlet slot and form a gap with the air outlet baffle. The air outlet slot is provided with an upwardly extending air diversion protrusion, which is arranged between two adjacent air guide ribs. This arrangement allows for the precise diversion and guidance of the hot air gathered in the air outlet slot: the gap between the air guide ribs and the air outlet baffle creates a space for airflow turning and acceleration, preventing the airflow from directly hitting the air outlet baffle and causing obstruction; while the air diversion protrusion further divides each air outlet slot unit into two sub-channels, allowing the hot airflow to be orderly diverted and guided to the inner and outer sides of the air outlet baffle for directional discharge. This increases the exhaust path and prevents the airflow from adjacent air outlets from interfering with each other and forming turbulence, thereby significantly improving the overall exhaust smoothness and heat dissipation efficiency of the air outlet slot.

[0017] Furthermore, the bottom of the main heat sink is provided with several heat dissipation columns extending into the second radial heat dissipation channel, and these columns are arranged radially. This arrangement effectively increases the heat exchange area within the channel and disrupts the airflow: these heat dissipation columns 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 within the airflow channel, causing the flowing cooling air to generate eddies and turbulence, thereby disrupting the laminar boundary layer and significantly improving the convective heat transfer coefficient between the air and the heat dissipation surface. This allows each stream of cooling air entering the second radial heat dissipation channel to more fully absorb and carry away heat, further enhancing the directional heat dissipation effect on high-heat areas.

[0018] Furthermore, the first fin includes a long first fin and a short first fin. The radial length of the short first fin is shorter than that of the long first fin. The short first fin is positioned close to the outer side of the long first fin. The short and long first fins are arranged alternately in the circumferential direction. By designing some fins as short first fins with shorter radial lengths and positioning them close to the outer side of the long first fins, the space constraints of the annular heat sink and other internal structures are effectively avoided, thus allowing a larger number of fin units to be accommodated within the limited circumferential space. At the same time, the alternating arrangement of long and short fins further optimizes space utilization, allowing for a denser arrangement of more heat exchange surfaces at the bottom of the heat sink, significantly increasing the overall heat dissipation area and laying a structural foundation for efficient heat exchange.

[0019] Furthermore, the heat sink is manufactured entirely from a single piece of metal. This design ensures that the heat sink has extremely high structural strength and dimensional accuracy, while eliminating contact thermal resistance between components. This allows for seamless heat conduction between all heat dissipation units, including the main heat sink, the annular heat sink, the heat dissipation fins, and the heat dissipation pillars. Heat can quickly diffuse along a continuous metal path to the entire heat sink, significantly improving overall thermal conductivity. In addition, the one-piece molding process simplifies the manufacturing process, reduces assembly costs and tolerance accumulation, and ensures product consistency and reliability.

[0020] Furthermore, the upper parts between the first and second fins are connected as one unit by connecting ribs. This configuration significantly enhances the structural stability and integrity of the fin assembly. The connecting ribs not only effectively suppress deformation and vibration of the slender fins during molding or use, but also serve as additional heat conduction paths, enabling efficient heat transfer and even distribution between the first and second fins, avoiding localized heat accumulation, thereby further improving the heat dissipation capability and structural reliability of the entire heat sink.

[0021] Furthermore, the bottom of the main heat sink is provided with a centrally located mounting hole and several connecting posts located outside the mounting hole. The socket is connected to the connecting posts via connectors. A fastening kit is fitted inside the socket hole of the socket. The inner wall of the socket hole 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 assembly. 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 a mounting hole and connecting posts at the bottom of the main heat sink, and a fastening kit with a first elastic arm is integrated and fitted inside the socket hole of the socket. Simultaneously, the first latching protrusion at the lower inner end of the first spring arm and the second latching protrusion at the lower outer end of the second spring arm, together with the first and second latching holes at the upper end of the lamp post assembly, form a double-locking structure. 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, only the upper end of the lamp post assembly needs to be inserted into the socket hole. The first and second spring arms can then 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 tensile and torsional strength of the lamp post assembly 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 locking structure is completely built into the socket hole, effectively reducing the transportation volume during disassembly and packaging, and further reducing logistics costs.

[0036] See Figures 1 to 12 The high-power 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.

[0037] 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 circumferentially provided between the main heat sink 11 and the annular heat sink 12. The main heat sink 11 has a top-opening light-emitting panel mounting area 141, and the annular heat sink 12 has a bottom-opening, ring-shaped LED strip mounting area 142. A socket 6 is connected to the bottom center of the heat sink 1. The bottom of the main heat sink 11 has a plurality of radially arranged heat dissipation fins 16. Each heat dissipation fin 16 includes a first fin 18 and a second fin 162 arranged radially outwards. The height of fin 18 is greater than the height of fin 162, and the bottom edges of fins 18 and 162 extend radially upwards. A first radial heat dissipation channel 163 with a bottom opening is formed between adjacent first fins 18. A second radial heat dissipation channel 164 with a bottom opening is formed between adjacent second fins 162, respectively connecting the first radial heat dissipation channel 163 and the lower side of the air outlet 119. A circumferential heat dissipation channel 165 connecting each of the first radial heat dissipation channels 163 and 164 is formed between adjacent first fins 18 and 162. The first radial heat dissipation channel 163 and the second radial heat dissipation channel 164 constitute the heat dissipation channel formed between adjacent heat dissipation fins 16.

[0038] The light-emitting component 2 includes a high-power main light-emitting board 21 and a ring light strip 22. The high-power main light-emitting board 21 has a power of 100W to 1000W 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 ring light strip 22 is installed in the light strip mounting area 142. A ring light-transmitting element 159 is provided on the lower side of the light strip mounting area 142.

[0039] The annular bottom cover 3 includes a hollow cone-shaped cover 31. The inner side of the cover 31 is used to fit against the bottom periphery of a plurality of heat dissipation fins 16. The cover 31 is provided with a 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 covered by a connecting structure at the bottom of each second fin 162 of the main heat sink 11, so that the annular light-transmitting element 159 is sandwiched between the support edge 33 and the lower end of the annular heat sink 12 to form a fixed position. The inner end of the guide edge 32 abuts against the outer side of the first fin 18. The guide edge 32 is provided with a plurality of first air inlets 34 for connecting the bottom of each first radial heat dissipation channel 163.

[0040] The floating bottom cover 4 has a cover cavity with an upper opening that is adapted to the bottom surface of the first fin 18. The cover cavity is used to fit the inner side of the bottom of the heat dissipation fin 16 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 located in the middle. The lower outer periphery of the socket 6 has a snap-fit ​​edge 66 extending obliquely upward. The cover cavity has a number of 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 first fin 18 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 circumferential heat dissipation channel 165 and the outer first air intake channel 42. The first air inlet 34 is located in the first air intake channel 42. The first clearance hole 41 of the floating bottom cover 4 and the cover cavity form a first radial heat dissipation channel 163 and the outer second air intake channel 43.

[0041] The lamp holder 5 includes a lamp pole assembly 50. The upper end of the lamp pole assembly 50 is assembled into the socket hole at the bottom of the socket 6 through a snap-fit ​​structure via a first clearance hole 41.

[0042] Compared with the prior art, the high-power backlit floor lamp of the present invention, by setting the heat sink 1 to include a main heat sink 11 and an annular heat sink 12, with an air outlet 119 arranged circumferentially between them, and first fins 18 and second fins 162 of different heights radially arranged at the bottom of the main heat sink 11, forming a first radial heat dissipation channel 163, a second radial heat dissipation channel 164 and a connected circumferential heat dissipation channel 165 between adjacent fins, and combining it with the light-emitting components 2 of the high-power main light-emitting plate 21 and the annular light strip 22, the annular bottom cover 3 with an air guide edge 32 and a support edge 33, the suspended bottom cover 4 with a cover cavity and a first clearance hole 41, and the lamp holder 5 assembly, in a coordinated manner. This design constructs a three-dimensional, multi-level air circulation path. 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, thereby generating 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 for the second fin 162. Simultaneously, based on the phase... Similarly, external 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. The airflow flows through the surface of the first fin 18 and the second fin 162 in sequence, carrying away the accumulated heat and further enhancing the heat dissipation effect on the second fin 162 and even the entire heat sink 1. The circumferential heat dissipation channel 165 uses the hot air pressure difference to enable the incoming airflow to spread quickly and evenly into each of the first radial heat dissipation channels 163, effectively avoiding local hot spots and ensuring a balanced temperature distribution throughout the heat sink 1. This 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 of high-power floor lamps caused by sealed or solid structures. 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 suspended 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.

[0043] See Figures 3 to 6In 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.

[0044] See Figures 3 to 6 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 sections, and adjacent air guide ribs 17 form an air outlet 119 corresponding to the second radial heat dissipation channel 164, so that several air outlets 119 correspond one-to-one with the second radial heat dissipation channel 164. Through this arrangement, the exhaust path of hot air is effectively regulated and accelerated: 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 guide each air outlet 119 but also... The air vent 119 is physically isolated to prevent mutual interference and turbulence between adjacent channels. More importantly, it divides the originally annular air vent 119 into independent exhaust units that correspond one-to-one with 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 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 fastest speed, thereby forming a strong and orderly negative pressure suction zone at the top of the heat sink 1. This further enhances the intake efficiency of cold air at the bottom, and qualitatively improves the smoothness and heat dissipation capacity of the entire self-driven air-cooling cycle.

[0045] See Figures 3 to 9In 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.

[0046] See Figures 3 to 9 In 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.

[0047] See Figures 3 to 9In 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.

[0048] See Figures 6 to 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.

[0049] See Figure 7 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.

[0050] See Figure 7 and Figure 9In one embodiment, the upper part between the first fin 18 and the second fin 162 is connected as one unit by a connecting rib 191. The lower side of the middle part of the heat dissipation fin 16 is provided with a heat diffusion port 192, so that adjacent heat diffusion ports 192 form a circumferential heat dissipation channel 165 connecting each of the first radial heat dissipation channel 163 and the second radial heat dissipation channel 164. With this arrangement, the upper part between the first fin 18 and the second fin 162 is connected as one unit by the connecting rib 191. This structure can significantly enhance the structural stability and integrity of the fin group: the connecting rib 191 not only effectively suppresses the deformation and vibration of the slender fins during molding or use, but also serves as an additional heat conduction path, enabling heat to be efficiently transferred and evenly distributed between the first fin 18 and the second fin 162, avoiding local heat accumulation, thereby further improving the heat diffusion capability and structural reliability of the entire heat sink 1.

[0051] See Figure 7 and Figure 8In 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, preferably a screw. A snap-fit ​​kit 61 is mounted and connected to the inner end of the socket hole of the socket 6. The inner wall of the socket hole has a first spring arm 62 with a free lower end, and the inner wall of the snap-fit ​​kit 61 has a second spring arm 611 with a free lower end. The snap-fit ​​structure includes a... The first latching protrusion 63 at the lower inner end of the first spring arm 62, the second latching protrusion 612 at the lower outer end of the second spring arm 611, and the first latching hole 53 and the second latching hole 54 located at the upper end of the lamp post assembly. The lamp post assembly 50 has a hollow structure. When the lamp post is installed in place relative to the socket 6, the second latching protrusion 612 engages with the second latching hole 54 from the inside, and the first latching protrusion 63 engages with the first latching hole 53 from the outside. With this arrangement, the socket 6 can be detachably installed by providing an assembly hole 110 and a connecting post 100 at the bottom of the main heat sink 11. A fastening kit 61 with a first spring arm 62 is integrated and assembled 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 assembly. This design, while enabling modular assembly and disassembly of the lamp holder 5 and the heat sink 1, significantly improves the ease of assembly and connection reliability: 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 be easily engaged. Through elastic deformation, the first latching protrusion 63 and the second latching protrusion 612 automatically engage with their corresponding latching holes from the outside and inside, respectively, forming a stable connection with bidirectional interlocking. This ensures the tensile and torsional strength of the lamp post assembly 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 latching structure is completely built into the socket hole, effectively reducing the transportation volume during disassembly and packaging, and further reducing logistics costs.

[0052] See Figures 2 to 9In 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, and several snap-fit ​​pieces 141 extend from its bottom. These snap-fit ​​pieces 141 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 heat sink 141 via the connecting posts 100 at its bottom passing through the second clearance hole 210. The top of the body 11 is connected so that the high-power main light-emitting plate 21 is pressed against the clamping edge 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.

[0053] See Figures 2 to 7 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 so that the annular bottom cover 3 is fixed to the outer periphery of the bottom of a plurality of heat dissipation fins 16 of the heat sink 1.

[0054] See Figure 2 and Figure 6In one embodiment, the annular light strip 22 is fixed to the top wall of the light strip mounting area 142 by adhesive; it also includes an annular diffuser plate 152, and 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 configuration, by setting second steps 144 on both sides of the light strip mounting area 142 at the bottom of the annular heat sink 12, and placing the annular diffuser plate 152 on the second steps 144 to support the annular light-transmitting element 159, this structure achieves 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 steps 144 form precise radial and axial positioning of 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, further enhancing the modular disassembly and assembly advantages of the product while ensuring optical effect.

[0055] See Figure 1 , 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 power connector 511 is provided in the upper lamp post hole 510 at the lower end of the upper lamp post 51. The first power 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 power 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 power connector 511 and the second power connector 512 form a power-conducting connection. This arrangement allows the lamp post assembly to be configured as a separate unit consisting of the upper lamp post 51 and the lower lamp post 52. The structure integrates a first power connector 511 and a second power connector 512 at the power connection ends of both lamp posts 51 and 52, respectively. A control switch 53 is also installed on the outside of the upper lamp post 51. This design, while enabling modular assembly and disassembly of the lamp post, further optimizes the convenience and safety of electrical connections: during assembly of 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. Furthermore, the split lamp post structure further reduces the packaging volume, ensuring reliable electrical performance while comprehensively considering the convenience of transportation, installation, and use.

[0056] In one embodiment (not shown), 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.

[0057] See Figure 1 , 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.

[0058] See Figure 1 , Figure 10 and Figure 12In one embodiment, a positioning groove 541 is provided on the side of the upper lamp post hole 510. A locking block 514 is provided on each side of the first power connector 511. When the first power connector 511 is installed opposite to the upper lamp post hole 510, it is fixed by being engaged in the positioning groove 541 by the locking block 514. The second power connector 512 is connected to the upper end of the lower lamp post 52 by a connector, preferably a screw. A locking groove 515 is provided on the outer side of the lower lamp post 52. A screw hole 516 communicating with the inner side of the upper lamp post 51 is provided on the outer side of the upper lamp post 51. The screw hole 516 is located below the first power connector 511. When the second power connector 512 is inserted into the hole of the upper lamp post 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, through... A positioning groove 541 is provided in the hole of the upper lamp post 51 to engage with the locking block 514 of the first power connector 511, enabling quick tool-free installation and axial positioning of the first power connector 511 and ensuring the accuracy of the alignment of the power connector terminals. At the same time, the second power 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 power connector 512. This structure combines electrical connection and mechanical fixation into one, which not only ensures the stability of the power 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 the convenience of disassembly and assembly while maintaining the integrity of the appearance of the lamp post assembly.

[0059] See Figure 1 , Figure 10 and Figure 12In 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 the inner shaft of the insertion hole 551 has a circumferential locking groove 552. The lower end of the second power connector 512 has a plurality of locking spring clips 518. When the lower end of the second power connector 512 is inserted into the insertion hole 551, the locking spring clips 518 engage in the locking 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 has a circumferential locking groove 552, and the lower end of the second power connector 512 has a plurality of locking spring clips 518. When the second power connector 512 is inserted into the insertion hole... When 551 is in place, 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, reducing maintenance costs and operational difficulty.

[0060] See Figure 12In one embodiment, a power drive device 7 is also 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 has 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 to fit against the inner wall of the tapered mounting hole 520. With this arrangement, the power drive device 7 is integrated on the bracket 71, and the bracket 71 is used to... The deformable and swingable abutment pieces 74 on both sides elastically fit 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 pieces 74 are 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 pieces 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, which further optimizes space utilization while ensuring electrical safety.

[0061] 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 are provided on both sides of the inner circumference of the connecting ring 75. The lower end of the bracket 71 is connected to the connecting edges 751 via a connector, preferably a screw. 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, preferably a screw, achieves electrical stability based on the lateral positioning of the abutment piece 74. The source drive device 7 enables 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 the 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.

[0062] 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, and the connection method involves a screw connecting to both the connecting hole and a threaded hole. 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 the connector, this structure, based on the lateral positioning of the abutment piece 74, realizes the power drive device. 7. Quick 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 is convenient for 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.
