Description

Technical Field

[0001] This utility model relates to the field of aluminum-based light strips, specifically to an aluminum-based light strip with finned three-dimensional heat dissipation. Background Technology

[0002] Aluminum-based LED strips are LED strips that use an aluminum substrate (metal-based printed circuit board) as the circuit carrier. In the field of LED lighting technology, aluminum-based LED strips are widely used in commercial lighting, home decoration, and industrial signage due to their excellent thermal conductivity and structural stability. However, with the increase in lighting power density, traditional aluminum substrate LED strips mainly rely on planar contact heat conduction, resulting in a single heat dissipation path. This leads to heat accumulation between the LED chips and the substrate, making it difficult to meet the heat dissipation requirements of high-brightness, long-term operation scenarios.

[0003] Existing improvement solutions expand the heat dissipation area by adding fixed heat dissipation fins to the surface of the aluminum substrate. However, such designs have structural defects: on the one hand, the fins extend in a single direction, which significantly increases the overall width of the light strip and limits its application in narrow installation spaces; on the other hand, the fixed fin layout can only achieve unidirectional air convection, which cannot make full use of multi-dimensional space for heat exchange, and dust is easy to accumulate between the fins, further reducing heat dissipation efficiency and affecting the uniformity of light output. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing an aluminum-based light strip with finned three-dimensional heat dissipation. By adding fixed heat dissipation fins to the surface of the aluminum substrate, the invention solves the technical problems of existing light strips having a significantly increased overall width, which limits their application in narrow installation spaces and makes it impossible to fully utilize multi-dimensional space for heat exchange.

[0005] The objective of this utility model is achieved through the following means:

[0006] A finned three-dimensional heat dissipation aluminum-based light strip includes an aluminum substrate, with LED beads uniformly mounted on the lower surface of the substrate. Magnetic assemblies are installed around the perimeter of the aluminum substrate. T-shaped grooves are uniformly formed on the upper surface of the aluminum substrate. A heat dissipation section, composed of fins, is slidably connected to the top of the T-shaped groove. Adjacent fins are rotatably connected. A transparent cover is slidably attached to the surface of the heat dissipation section and is slidably connected to the upper surface of the aluminum substrate. Holes are uniformly formed on the surface of the transparent cover. Copper pillars are uniformly added to the lower surface of the aluminum substrate. Graphene patches are connected between the copper pillars and the lower surface of the aluminum substrate. Positioning rods are inserted on both sides of the transparent cover, and the surfaces of the positioning rods are attached to the two ends of the T-shaped grooves.

[0007] The LED strip is attracted to the metal mounting surface of the lamp by magnetic components set around the aluminum substrate, achieving quick positioning and fixation;

[0008] According to the installation space requirements, manually adjust the rotation angle of adjacent fins in the heat dissipation section to form a three-dimensional heat dissipation array; slide the transparent cover along the upper surface of the aluminum substrate to make its inner wall completely fit the surface of the heat dissipation section.

[0009] Push the positioning rod so that its end abuts against the walls of the T-slot at both ends, fix the position of the transparent cover by friction, and restrict the sliding freedom of the heat dissipation part in the T-slot;

[0010] When the LED beads are working, the heat generated is conducted to the copper pillar through the aluminum substrate. The high thermal conductivity of the graphene patch quickly distributes the heat to the entire aluminum substrate. The fin structure of the heat dissipation part achieves natural convection heat dissipation by increasing the surface area, and the holes on the surface of the transparent cover form air flow channels to accelerate the heat exchange efficiency.

[0011] Furthermore, T-shaped plates are installed on both sides of the lower surface of the heat dissipation fins, and the T-shaped plates are slidably connected to the T-shaped grooves.

[0012] During assembly, the T-shaped plates installed on both sides of the lower surface of the heat dissipation fins are aligned with the T-shaped grooves pre-set on the surface of the aluminum substrate. The T-shaped plates are then fully embedded into the T-shaped groove cavity through a horizontal sliding operation until the two form a sliding connection structure.

[0013] Furthermore, limiting grooves are provided on both sides of the top of the T-shaped groove, and limiting protrusions are slidably connected to the inner cavity of the limiting grooves, and the limiting protrusions are connected to the transparent cover.

[0014] When the transparent cover is placed on the surface of the aluminum substrate, the limiting protrusion connected to its bottom slides into the inner cavity of the limiting groove opened on both sides of the top of the T-slot. The axial fixation of the transparent cover is achieved by the lateral constraint of the limiting protrusion on the limiting groove.

[0015] Furthermore, the magnetic suction assembly consists of a fixing plate, a fixing post, a protective sleeve, and a magnetic suction block, and the fixing plate is connected to the outer perimeter of the aluminum substrate.

[0016] The fixing plate of the magnetic component is installed on the preset mounting positions around the outside of the aluminum substrate using fasteners, so that the fixing post extends vertically. Then, the protective shell is fitted onto the top of the fixing post, and finally the magnetic block is embedded into the center of the inner cavity of the protective shell to complete the assembly.

[0017] Furthermore, the fixing post is located at the top center of the fixing plate, and the protective sleeve is connected to the top center of the fixing post, and the magnetic block is located at the center of the inner cavity of the protective sleeve.

[0018] During the assembly of the magnetic suction assembly, the fixing post is first vertically welded to the center of the top of the fixing plate. Then, the pre-formed protective shell is fixed to the top of the fixing post by threaded connection or interference fit. Finally, the magnetic block is pressed into the inner cavity of the protective shell to complete the seal.

[0019] Furthermore, a fixing seat is installed on the upper part of both sides of the transparent cover, and the positioning rod is inserted and connected to the fixing seat, and a magnetic suction plate is installed on the top of the fixing seat.

[0020] After covering the aluminum substrate with the transparent cover, align the mounting bases on the upper sides of the substrate with the external positioning rods. By vertically inserting the rods, the positioning rods are fully embedded into the inner cavity of the mounting bases. At this time, the magnetic plate at the top of the mounting bases magnetically attracts the corresponding metal parts.

[0021] The beneficial effects of this utility model are:

[0022] This aluminum-based light strip features a foldable and deployable fin array that breaks through the spatial limitations of traditional fixed heat dissipation structures. Through a T-shaped slide and a rotating connection mechanism, the heat dissipation components have three-dimensional deformation capabilities. In narrow installation scenarios, the fins can be folded to reduce lateral space occupation, and when heat dissipation needs to be enhanced, they can be unfolded to form a three-dimensional heat dissipation channel, which maintains a compact structure while expanding the heat exchange interface.

[0023] The rotational freedom of the fin assembly, combined with the porous structure of the transparent protective cover, creates a composite airflow channel that intersects vertically and horizontally. This utilizes the chimney effect and the dual effect of lateral ventilation to accelerate the replacement of hot air, thus improving heat dissipation efficiency compared to a unidirectional heat dissipation structure.

[0024] While providing physical protection, the transparent cover has equidistant airflow holes on its surface that form a self-cleaning airflow field. Combined with the modular sealing structure achieved by the detachable positioning rod, it effectively blocks the deposition path of dust in the gaps between the fins and avoids the problem of light decay caused by increased thermal resistance.

[0025] The copper pillar array on the lower surface of the aluminum substrate and the graphene thermal conductive layer form a dual-effect thermal conduction path. The graphene film realizes submicron-level heat conduction from the LED junction temperature to the substrate. The copper heat dissipation pillars vertically guide heat to the upper fin group by increasing the radiation area, forming a vertical heat flow layer conduction. Combined with the horizontal radiation heat dissipation of the upper adjustable angle fins, a multi-dimensional three-dimensional heat dissipation system is constructed. Attached Figure Description

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The specific implementation of the finned three-dimensional heat dissipation aluminum-based light strip includes an aluminum substrate 1, with LED beads 11 uniformly installed on the lower surface of the aluminum substrate 1, magnetic suction components 14 installed around the aluminum substrate 1, T-shaped grooves 2 uniformly opened on the upper surface of the aluminum substrate 1, a heat dissipation part 3 slidably connected to the top of the T-shaped groove 2, the heat dissipation part 3 being composed of fins, adjacent fins being rotatably connected, a transparent cover 6 slidably attached to the surface of the heat dissipation part 3, the transparent cover 6 being slidably connected to the upper surface of the aluminum substrate 1, holes uniformly opened on the surface of the transparent cover 6, copper pillars 12 uniformly added to the lower surface of the aluminum substrate 1, graphene patches 13 connected between the copper pillars 12 and the lower surface of the aluminum substrate 1, positioning rods 9 inserted on both sides of the transparent cover 6, the surfaces of the positioning rods 9 being attached to the two ends of the T-shaped groove 2.

[0035] The light strip is attracted to the metal mounting surface of the lamp by the magnetic components 14 arranged around the aluminum substrate 1, so as to achieve quick positioning and fixation.

[0036] According to the installation space requirements, manually adjust the rotation angle of adjacent fins in the heat dissipation part 3 so that the fin group forms a three-dimensional heat dissipation array; slide the transparent cover 6 along the upper surface of the aluminum substrate 1 so that its inner wall is completely attached to the surface of the heat dissipation part 3.

[0037] Push the positioning rod 9 so that its end abuts against the groove walls at both ends of the T-slot 2, fix the position of the transparent cover 6 by friction, and restrict the sliding freedom of the heat dissipation part 3 in the T-slot 2;

[0038] When the LED bead 11 is working, the heat generated is conducted to the copper pillar 12 through the aluminum substrate 1. The heat is then quickly distributed to the entire aluminum substrate 1 by the high thermal conductivity of the graphene patch 13. The fin structure of the heat dissipation part 3 achieves natural convection heat dissipation by increasing the surface area. The holes on the surface of the transparent cover 6 form air flow channels to accelerate heat exchange efficiency.

[0039] The sliding connection design between the T-slot 2 and the heat dissipation part 3 enables quick disassembly and maintenance of the heat dissipation component, solving the technical problem of the traditional fixed and non-replaceable heat dissipation structure of the light strip.

[0040] The adjacent fins adopt a rotating connection structure, which allows the heat dissipation part 3 to adjust the unfolding angle according to the installation space constraints, so as to maintain an effective heat dissipation area in a narrow environment and break through the limitations of the traditional fixed angle of fins.

[0041] The copper pillar 12 and the graphene patch 13 form a dual heat conduction path, which quickly disperses the concentrated heat source of the LED bead 11 to the entire aluminum substrate 1. Combined with the fin heat dissipation structure, a three-dimensional heat conduction link is formed, which significantly improves heat dissipation efficiency.

[0042] like Figure 3 and Figure 5 As shown, T-shaped plates 4 are installed on both sides of the lower surface of the heat dissipation part 3, and the T-shaped plates 4 are slidably connected to the T-shaped groove 2.

[0043] During the assembly process, the T-shaped plates 4 installed on both sides of the lower surface of the heat dissipation part 3 are aligned with the T-shaped grooves 2 pre-set on the surface of the aluminum substrate 1. The T-shaped plates 4 are fully embedded into the inner cavity of the T-shaped grooves 2 through horizontal sliding operation until the two form a sliding connection structure.

[0044] The sliding connection design of T-plate 4 and T-slot 2 enables quick positioning and installation of heat dissipation part 3 and aluminum substrate 1, while avoiding the risk of vertical displacement, ensuring the structural stability of heat dissipation component during operation, and optimizing the heat conduction path to improve heat dissipation efficiency.

[0045] like Figure 4 and Figure 6 As shown, a limiting groove 5 is provided on both sides of the top of the T-shaped groove 2, and a limiting protrusion 7 is slidably connected to the inner cavity of the limiting groove 5, and the limiting protrusion 7 is connected to the transparent cover 6.

[0046] When the transparent cover 6 covers the surface of the aluminum substrate 1, the limiting protrusion 7 connected to its bottom slides into the inner cavity of the limiting groove 5 opened on both sides of the top of the T-shaped groove 2. The axial fixation of the transparent cover 6 is achieved by the lateral constraint of the limiting protrusion 7 by the limiting groove 5.

[0047] The matching structure of the limiting groove 5 and the limiting protrusion 7 effectively prevents the transparent cover 6 from shifting or falling off under working vibration or external force, while maintaining a tight fit between the cover and the surface of the aluminum substrate 1, thus improving the equipment's protective performance and structural reliability.

[0048] like Figure 3 As shown, the magnetic attraction assembly 14 consists of a fixing plate 15, a fixing post 16, a protective sleeve 17, and a magnetic block 18. The fixing plate 15 is connected to the outer periphery of the aluminum substrate 1. The fixing plate 15 of the magnetic attraction assembly 14 is installed in the preset mounting positions on the outer periphery of the aluminum substrate 1 using fasteners, so that the fixing post 16 extends vertically. Then, the protective sleeve 17 is fitted onto the top of the fixing post 16, and finally, the magnetic block 18 is embedded into the center of the inner cavity of the protective sleeve 17 to complete the assembly. The magnetic attraction assembly 14 achieves rapid assembly with the aluminum substrate 1 through modular design. The protective sleeve 17 provides physical isolation and protection for the magnetic block 18, avoiding magnetic failure caused by external impact or environmental corrosion, and extending the service life of the magnetic attraction function. The fixing post 16 is located at the top center of the fixing plate 15, and the protective sleeve 17 is connected to the top center of the fixing post 16. The magnetic block 18 is located at the center of the inner cavity of the protective sleeve 17. During the assembly of the magnetic suction assembly 14, the fixing post 16 is first vertically welded to the top center of the fixing plate 15. Then, the pre-formed protective sleeve 17 is fixed to the top of the fixing post 16 by threaded connection or interference fit. Finally, the magnetic block 18 is pressed into the inner cavity of the protective sleeve 17 to complete the seal. The fixing post 16 serves as the supporting frame of the magnetic suction assembly 14, ensuring the installation height and axial accuracy of the magnetic block 18. The connection structure between the protective sleeve 17 and the fixing post 16 effectively disperses external stress and avoids the performance degradation of the magnetic block 18 due to direct force.

[0049] like Figure 6 As shown, a fixing seat 8 is installed on the upper part of both sides of the transparent cover 6, and the positioning rod 9 is inserted and connected to the fixing seat 8. A magnetic suction plate 10 is installed on the top of the fixing seat 8.

[0050] After the transparent cover 6 is placed on the surface of the aluminum substrate 1, the fixing base 8 installed on the upper part of both sides is aligned with the external positioning rod 9. The positioning rod 9 is fully embedded into the inner cavity of the fixing base 8 by vertical insertion. At this time, the magnetic suction plate 10 at the top of the fixing base 8 magnetically attracts the corresponding metal parts.

[0051] The insertion structure of the positioning rod 9 and the fixing seat 8 enables the precise positioning of the transparent cover 6. The additional design of the magnetic plate 10 further enhances the fixing effect of the cover. While simplifying the disassembly and assembly process, it avoids the obstruction of the transparency of the transparent cover 6 by the traditional locking mechanism.

[0052] The process of a finned three-dimensional heat dissipation aluminum-based light strip in this embodiment is as follows: LED beads 11 are evenly arranged on the lower surface of the aluminum substrate 1, and copper pillars 12 are added to the lower surface of the aluminum substrate 1 at the corresponding positions of the LED bead 11 installation area. The copper pillars 12 and the aluminum substrate 1 are thermally connected through graphene patches 13 to form a dual heat conduction path.

[0053] The fixing plate 15 is fixed to the preset mounting positions around the outer side of the aluminum substrate 1 with fasteners, so that the fixing post 16 extends vertically; the protective sleeve 17 is fixed to the top of the fixing post 16 by threaded connection or interference fit, and finally the magnetic block 18 is embedded into the center of the inner cavity of the protective sleeve 17 to complete the modular assembly of the magnetic component 14.

[0054] Align the T-shaped plates 4 on both sides of the lower surface of the heat dissipation part 3 with the T-shaped grooves 2 pre-set on the upper surface of the aluminum substrate 1, and slide them horizontally to make the T-shaped plates 4 completely embedded in the inner cavity of the T-shaped grooves 2, thus establishing a sliding connection structure. Adjacent fins are connected by rotation to form an adjustable angle three-dimensional heat dissipation array.

[0055] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
