Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, specifically to an LED light strip with good heat dissipation performance. Background Technology

[0002] LED light strips are flexible or rigid strip light sources composed of multiple LEDs. They are characterized by energy saving, long lifespan, rich colors, and bendability, and are widely used in decorative lighting, atmosphere creation, and functional lighting.

[0003] For example, patent application number 202420850670.1 published on the China Patent Network, entitled "A Heat Dissipation Structure for LED Light Strips," includes an H-shaped heat sink disposed at the lower part of the housing, a protrusion disposed at the bottom of the cavity inside the housing near the side, a through hole disposed on the substrate, and a heat dissipation patch disposed below the substrate. This utility model provides a heat dissipation structure for LED light strips. By separating the substrate from the housing and forming a cavity inside the housing, heat dissipation is facilitated. The intermittent arrangement of the heat sinks improves heat dissipation capacity without requiring openings in the housing, thus maintaining the protective effect of the housing. Furthermore, the intermittent arrangement minimizes the impact on the bending performance of the LED light strip.

[0004] However, the heat dissipation method of existing light strips is relatively simple, mainly by setting up a patch inside the housing for heat dissipation. However, the heat absorbed by the patch inside the housing will continue to accumulate inside the housing and will not cause the heat to be dissipated to the external environment.

[0005] Therefore, it is necessary to redesign and modify LED light strips with good heat dissipation performance. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an LED light strip with good heat dissipation performance, which has the advantage of improving heat dissipation efficiency. This solves the problem that the heat dissipation method of existing light strips is relatively simple, mainly by setting a patch inside the shell for heat dissipation. However, the heat absorbed by the patch is still continuously accumulated inside the shell and does not cause the heat to be dissipated to the external environment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an LED light strip with good heat dissipation performance, including a housing;

[0008] LED adhesive strip installed inside the housing;

[0009] The lamp strip has an internal lamp bead assembly;

[0010] A heat-conducting plate is fixedly connected inside the lamp adhesive strip. Extension plates are fixedly connected to both sides of the top of the heat-conducting plate. The end of the extension plate away from the heat-conducting plate passes through the lamp adhesive strip and the outer shell in sequence and extends to the top of the outer shell. The lamp adhesive strip is completely wrapped and fixed to the surface of the extension plate and the heat-conducting plate. A heat exchange plate is provided at the end of the extension plate located at the top of the outer shell. Several slots are opened on the surface of the heat exchange plate. The top of the heat exchange plate can exchange heat through contact.

[0011] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to both sides of the bottom of the heat exchange plate, the side of the connecting plate away from the heat exchange plate extends to the outside of the heat exchange plate, and a connecting keyway is provided at the end of the connecting plate located on the outside of the heat exchange plate.

[0012] As a preferred embodiment of this utility model, an elastic frame is fixedly connected to the top of the lamp adhesive strip. The elastic frame is sleeved on the surface of the extension plate, and the side of the elastic frame away from the lamp adhesive strip contacts the inner surface of the outer shell. The elastic frame is elastic.

[0013] As a preferred embodiment of this utility model, heat dissipation grooves are provided on both the left and right sides of the outer casing, and the lamp adhesive strip is exposed to the outside of the outer casing through the heat dissipation grooves.

[0014] As a preferred embodiment of this utility model, heat-conducting fins are fixedly connected to both the left and right sides of the outer shell, and heat-conducting adhesive strips are inserted into the interior of the heat-conducting fins.

[0015] As a preferred embodiment of this utility model, a contact element is fixedly connected to the inner side of the heat-conducting fin. The side of the contact element away from the heat-conducting fin passes through the heat dissipation groove and contacts the surface of the lamp adhesive strip. The contact element and the heat dissipation groove are interlocked.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model directly absorbs the heat of the LED beads by setting a heat-conducting plate, and the extension plate conducts the heat to the heat exchange plate on the top of the shell. This breaks through the limitations of traditional internal patch heat dissipation, avoids heat accumulation in the shell, and the grooves on the surface of the heat exchange plate increase the contact area with air, so as to quickly dissipate heat through thermal convection and significantly improve heat dissipation efficiency.

[0018] 2. This utility model supports the installation of additional heat dissipation components through the connecting keyway, which can flexibly expand the heat dissipation capacity according to the heat dissipation requirements. The connecting plate extends to the outside of the heat exchange plate, which enhances the connection strength between the heat exchange plate and the outer shell and avoids structural loosening due to vibration or thermal deformation.

[0019] 3. This utility model uses the elasticity of the elastic frame to buffer the deformation difference between the extension plate and the outer shell caused by temperature changes, avoiding structural cracking or poor contact. The elastic frame fits tightly against the inner wall of the outer shell, reducing the intrusion of external dust or moisture, while fixing the position of the extension plate to ensure a continuous and stable heat conduction path.

[0020] 4. This utility model allows the exposed part of the lamp strip to directly contact the outside air, achieving rapid heat dissipation through thermal radiation and convection, thereby reducing the internal temperature of the lamp strip. The heat dissipation groove reduces the amount of material used in the outer shell, reducing the overall weight of the lamp strip while maintaining structural strength.

[0021] 5. This utility model further expands the heat dissipation area by using heat-conducting fins, and uses heat-conducting adhesive strips to evenly distribute heat to the fin surface, thereby improving heat dissipation efficiency. The heat-conducting adhesive strips fill the gaps inside the fins, enhance structural stability, and prevent the fins from softening due to high temperature or deforming under stress.

[0022] 6. This utility model directly conducts the heat from the surface of the lamp adhesive strip to the heat-conducting fins through the contact element, forming a second heat dissipation channel to avoid local overheating. The contact element and the heat dissipation groove are designed to be plugged in, which enhances the connection strength between the heat-conducting fins and the outer shell and prevents the fins from falling off due to external force.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The lamp adhesive strip 2 is installed inside the outer casing 1;

[0031] The LED strip 2 has an LED bead assembly 3 installed inside it;

[0032] A heat-conducting plate 4 is fixedly connected inside the lamp adhesive strip 2. Extension plates 5 are fixedly connected to both sides of the top of the heat-conducting plate 4. The end of the extension plate 5 away from the heat-conducting plate 4 passes through the lamp adhesive strip 2 and the outer shell 1 in sequence and extends to the top of the outer shell 1. The lamp adhesive strip 2 is completely wrapped and fixed to the surface of the extension plate 5 and the heat-conducting plate 4. A heat exchange plate 6 is provided at the end of the extension plate 5 located at the top of the outer shell 1. Several slots 7 are opened on the surface of the heat exchange plate 6. The top of the heat exchange plate 6 can exchange heat by contact.

[0033] refer to Figure 3 A connecting plate 8 is fixedly connected to both sides of the bottom of the heat exchange plate 6. The side of the connecting plate 8 away from the heat exchange plate 6 extends to the outside of the heat exchange plate 6. A connecting keyway 9 is provided at the end of the connecting plate 8 located on the outside of the heat exchange plate 6.

[0034] As a technical optimization of this utility model, the keyway 9 supports the installation of additional heat dissipation components, and the heat dissipation capacity can be flexibly expanded according to the heat dissipation requirements. The connecting plate 8 extends to the outside of the heat exchange plate 6, which enhances the connection strength between the heat exchange plate 6 and the outer shell 1 and avoids structural loosening due to vibration or thermal deformation.

[0035] refer to Figure 4 The top of the lamp adhesive strip 2 is fixedly connected to an elastic frame 10. The elastic frame 10 is sleeved on the surface of the extension plate 5. The side of the elastic frame 10 away from the lamp adhesive strip 2 is in contact with the inner surface of the outer shell 1. The elastic frame 10 is elastic.

[0036] As a technical optimization of this utility model, the elasticity of the elastic frame 10 can buffer the deformation difference between the extension plate 5 and the outer shell 1 caused by temperature changes, so as to avoid structural cracking or poor contact. The elastic frame 10 fits tightly against the inner wall of the outer shell 1 to reduce the intrusion of external dust or moisture, while fixing the position of the extension plate 5 to ensure a continuous and stable heat conduction path.

[0037] refer to Figure 4 Heat dissipation grooves 11 are provided on both the left and right sides of the outer casing 1, and the lamp adhesive strip 2 is exposed to the outside of the outer casing 1 through the heat dissipation grooves 11.

[0038] As a technical optimization of this utility model, the exposed part of the lamp strip 2 is in direct contact with the outside air, and heat dissipation is achieved through thermal radiation and convection, thereby reducing the internal temperature of the lamp strip 2. The heat dissipation groove 11 reduces the material used in the outer shell 1, reduces the overall weight of the lamp strip, and maintains the structural strength.

[0039] refer to Figure 4 Heat-conducting fins 12 are fixedly connected to the left and right sides of the outer shell 1, and heat-conducting adhesive strips 13 are inserted into the inside of the heat-conducting fins 12.

[0040] As a technical optimization of this utility model, the heat dissipation area is further expanded by the heat-conducting fin plate 12, and the heat is evenly distributed to the surface of the fins by the heat-conducting adhesive strip 13 to improve the heat dissipation efficiency. The heat-conducting adhesive strip 13 fills the gaps inside the fin plate to enhance the structural stability and prevent the fin plate from softening or deforming due to high temperature or stress.

[0041] refer to Figure 4 A contact 14 is fixedly connected to the inner side of the heat-conducting fin 12. The side of the contact 14 away from the heat-conducting fin 12 passes through the heat dissipation groove 11 and contacts the surface of the lamp adhesive strip 2. The contact 14 and the heat dissipation groove 11 are interlocked.

[0042] As a technical optimization of this utility model, the heat on the surface of the lamp adhesive strip 2 is directly conducted to the heat-conducting fin plate 12 through the contact member 14 to form a second heat dissipation channel, thereby avoiding local overheating. The contact member 14 is designed to be plugged into the heat dissipation groove 11 to enhance the connection strength between the heat-conducting fin plate 12 and the outer shell 1, and to prevent the fin plate from falling off due to external force.

[0043] The working principle and usage process of this utility model are as follows: When the LED bead assembly 3 is working, it generates heat. This heat is first conducted through the inside of the LED adhesive strip 2 to the heat-conducting plate 4 that is fixedly connected to it. The heat-conducting plate 4 serves as the core heat dissipation structure, transferring the heat longitudinally along the extension plates 5 on both sides of its top. The extension plates 5 penetrate the LED adhesive strip 2 and the outer shell 1, reaching the top of the outer shell. The heat exchange plate 6 at the top of the extension plate 5 expands the heat dissipation area through multiple slots 7 on its surface, allowing direct contact with the outside air and rapid heat dissipation through thermal convection. The connecting plate 8 at the bottom of the heat exchange plate 6 supports modular expansion through the connecting keyways 9 on both sides, allowing the addition of heat dissipation components to enhance heat dissipation capacity. It also provides a connection channel for bolts. The heat dissipation slots 11 on both sides of the outer shell 1 expose part of the LED adhesive strip 2 to the external environment, allowing direct heat dissipation through thermal radiation and convection. At the same time, the heat-conducting fins 12 are in close contact with the surface of the LED adhesive strip 2 through the plugged contact parts 14, transferring heat from the LED adhesive strip 2 to the fins. Combined with the internal heat-conducting adhesive strip 13, the heat dissipation efficiency is further improved.

[0044] In summary, this LED light strip with excellent heat dissipation performance directly absorbs the heat from the LED beads by setting the heat-conducting plate 4, and the extension plate 5 conducts the heat to the heat exchange plate 6 on the top of the shell. This breaks through the limitations of traditional internal surface-mount heat dissipation, avoids heat accumulation in the shell, and the slots 7 on the surface of the heat exchange plate 6 increase the contact area with air, allowing for rapid heat dissipation through thermal convection, which significantly improves heat dissipation efficiency.
