Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, and in particular to a novel LED light strip heat dissipation structure. Background Technology

[0002] Traditional LED strips (especially high-brightness, high-density LED chips) generate a significant amount of heat during prolonged operation. Poor heat dissipation can lead to accelerated light decay, shortened lifespan, color temperature drift, and even damage to the LED chips. Common heat dissipation problems include:

[0003] 1. Passive heat dissipation is inefficient: It relies solely on the LED strip substrate or a simple metal casing to conduct heat. The heat dissipation area is small, the efficiency is low, and heat is easily accumulated.

[0004] 2. Installation method affects heat dissipation: Embedded installation or tight mounting will prevent heat from dissipating into the surrounding air.

[0005] 3. Weight and maintenance: Traditional heat dissipation structures (such as heavy aluminum channels) increase weight and cost, and are inconvenient to disassemble and maintain.

[0006] 4. Poor heat conduction path: The heat transfer efficiency from the LED to the external heat dissipation structure is low, and there is a thermal resistance bottleneck.

[0007] Therefore, there is an urgent need for a new type of LED light strip heat dissipation structure that is compact, has high heat dissipation efficiency, is easy to install and maintain. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel LED light strip heat dissipation structure, comprising:

[0009] A housing having a cavity inside;

[0010] The mounting port is located on the bottom surface of the housing along the length of the housing and communicates with the cavity;

[0011] A light strip light source is disposed within the cavity;

[0012] A magnetic base, comprising two magnetic rubber strips, which are disposed on the bottom surface of the housing along the length of the housing and located on both sides of the mounting opening. A heat dissipation space is formed between the two magnetic rubber strips. A group of heat dissipation holes communicating with the heat dissipation space is evenly opened on the side of the magnetic rubber strip along the length of the magnetic rubber strip.

[0013] A heat dissipation device is provided on the housing and located in the heat dissipation space. The heat dissipation device includes an elastic aluminum sheet provided on the housing and located at the mounting port for mounting and placing a light strip light source, a heat-conducting component provided between the elastic aluminum sheet and the light strip light source, and a plurality of wave-shaped heat dissipation fin groups provided along the length direction of the elastic aluminum sheet at the bottom end of the elastic aluminum sheet and located in the heat dissipation space. The wave-shaped heat dissipation fin groups include main fins and auxiliary fins, and an airflow channel is formed between adjacent main fins and auxiliary fins. The height of the main fins is 1.5-2 times that of the auxiliary fins.

[0014] Mounting bracket, which is mounted on an external wall for magnetic attachment with a magnetic base.

[0015] Preferably, both the main fin and the auxiliary fin are covered with a nano-silicon carbide thermal conductive coating, the thickness of which is 50-100 μm.

[0016] Preferably, the light strip light source includes a flexible circuit board mounted on the flexible aluminum sheet along the length of the flexible aluminum sheet, and a plurality of LED beads evenly disposed on the flexible circuit board along the length of the flexible circuit board.

[0017] Preferably, the heat-conducting component includes a heat dissipation window formed in the flexible circuit board and a heat-conducting copper foil disposed in the heat dissipation window for conducting the heat emitted by the LED beads to the elastic aluminum sheet.

[0018] Preferably, the width of the mounting opening is smaller than the width of the cavity inside the housing, and the bottom surface of the housing is provided with an aluminum sheet slot for engaging with the edge of the elastic aluminum sheet around the mounting opening. The housing is provided with a locking member for locking the elastic aluminum sheet in the aluminum sheet slot.

[0019] Preferably, the housing includes a housing body, a light-emitting window opened on the upper end face of the housing body, and a light strip panel disposed on the housing body and located at the light-emitting window.

[0020] Preferably, the mounting bracket has a trapezoidal cross-section, and the end face of the mounting bracket that magnetically engages with the magnetic base has a mounting bracket heat dissipation port for expanding the heat dissipation space.

[0021] Compared with the prior art, this utility model has at least the following beneficial effects:

[0022] 1. This utility model constructs a heat dissipation structure integrating magnetic installation, forced convection heat dissipation channel at the bottom, and large-area high-efficiency heat dissipation fins. It solves the problems of difficult heat dissipation and inconvenient installation and maintenance of traditional light strips in narrow spaces. The use of wave-shaped heat dissipation fins greatly increases the heat dissipation surface area and improves the heat dissipation efficiency per unit space. The height difference between the main fins and the auxiliary fins forms a more effective chimney effect and turbulence, accelerating the exhaust of hot air from the top heat dissipation space. The airflow channel between adjacent fins guides the airflow direction, optimizes airflow, and enhances the convection heat dissipation effect.

[0023] 2. This utility model enables quick, secure, and tool-free installation and disassembly of the light strip and mounting bracket by setting a magnetic base, which greatly facilitates construction and maintenance. The gap between the two magnetic rubber strips forms the core bottom heat dissipation channel, ensuring smooth airflow. The heat dissipation hole group located on the side of the magnetic rubber strip directly connects to the heat dissipation space, significantly increasing the heat dissipation surface area and promoting air to enter and exit the heat dissipation space from the side, forming convection and improving heat dissipation efficiency.

[0024] 3. This utility model further enhances the heat dissipation capacity of the fin assembly by setting a nano-silicon carbide thermal conductive coating, making the heat dissipation structure more efficient. It also controls the coating thickness to ensure a significant coating effect, while avoiding excessive thickness that could lead to high costs or peeling. Attached Figure Description

[0037] like Figures 1 to 3 As shown, an embodiment of this utility model provides a novel LED light strip heat dissipation structure, comprising:

[0038] The housing has a cavity 15. The housing includes a housing body 11, a light-emitting window 12 on the upper surface of the housing body, and a light strip panel 13 on the housing body and located at the light-emitting window. The light strip panel can affect the light output effect (such as soft light, anti-glare, etc.), and the light strip panel is detachable for easy maintenance of LED beads.

[0039] Mounting port 14 is located on the bottom surface of the housing along the length of the housing and communicates with the cavity;

[0040] A light strip light source is disposed within the cavity;

[0041] The magnetic base includes two magnetic rubber strips 21, which are located on the bottom surface of the housing along the length of the housing and on both sides of the mounting opening. A heat dissipation space 22 is formed between the two magnetic rubber strips. A group of heat dissipation holes (not shown in the figure) communicating with the heat dissipation space are evenly opened on the side of the magnetic rubber strip along the length of the magnetic rubber strip. By setting the magnetic base, the light strip and the mounting bracket can be quickly, firmly and without tools installed and disassembled, which greatly facilitates construction and maintenance. The gap between the two magnetic rubber strips forms the core bottom heat dissipation channel, ensuring smooth airflow. The group of heat dissipation holes on the side of the magnetic rubber strip directly connects to the heat dissipation space, significantly increasing the heat dissipation surface area and promoting the entry and exit of air from the side into the heat dissipation space, forming convection and improving heat dissipation efficiency.

[0042] A heat dissipation device is installed on the housing and located in the heat dissipation space. The heat dissipation device includes an elastic aluminum sheet 31 installed on the housing and located at the mounting port for mounting a light strip light source, a heat-conducting component between the elastic aluminum sheet and the light strip light source, and a plurality of wave-shaped heat dissipation fin groups located at the bottom of the elastic aluminum sheet along the length of the elastic aluminum sheet and located in the heat dissipation space. The wave-shaped heat dissipation fin groups include main fins 32 and auxiliary fins 33. An airflow channel 34 is formed between adjacent main fins and auxiliary fins. The height of the main fins is 1.5-2 times that of the auxiliary fins. This embodiment of the utility model uses wave-shaped heat dissipation fins, which greatly increases the heat dissipation surface area and improves the heat dissipation efficiency per unit space. There is a height difference between the main fins and the auxiliary fins. Therefore, the main fins (high) guide the hot airflow upward, and the auxiliary fins (low) assist in turbulence and increase the heat dissipation area, forming a more effective chimney effect and turbulence, accelerating the exhaust of hot air from the top heat dissipation space. The airflow channel between adjacent fins guides the airflow direction, optimizes airflow, and enhances the convective heat dissipation effect.

[0043] Mounting bracket 41 is mounted on an external wall for magnetic attraction with a magnetic base. The mounting bracket has a trapezoidal cross-section, and the end face of the mounting bracket that magnetically engages with the magnetic base has a mounting bracket heat dissipation port 42 for expanding the heat dissipation space. This embodiment of the utility model optimizes the airflow environment of the bottom heat dissipation space by setting the mounting bracket heat dissipation port, ensuring that the heat dissipation channel formed by the magnetic base is unobstructed, maximizing the heat dissipation effect of bottom convection, and complementing the heat dissipation of the top fins.

[0044] Furthermore, both the main fins and auxiliary fins are covered with a nano-silicon carbide thermal conductive coating (not shown in the figure). The thickness of the nano-silicon carbide thermal conductive coating is 50-100μm. This embodiment of the invention further enhances the heat dissipation capacity of the fin assembly by setting a nano-silicon carbide thermal conductive coating, making the heat dissipation structure more efficient. Silicon carbide material has excellent thermal radiation performance. The coating can more efficiently dissipate the heat inside the fins into the surrounding environment in the form of infrared radiation. Controlling the coating thickness ensures a significant coating effect, while avoiding excessive thickness that could lead to high costs or potential peeling.

[0045] Furthermore, the light strip light source includes a flexible circuit board 51 mounted on the elastic aluminum sheet along the length of the elastic aluminum sheet, and a plurality of LED beads 52 evenly disposed on the flexible circuit board along the length of the flexible circuit board.

[0046] Furthermore, the heat-conducting component includes a heat dissipation window 61 opened in the flexible circuit board and a heat-conducting copper foil 62 disposed in the heat dissipation window for conducting the heat emitted by the LED beads to the elastic aluminum sheet. In this embodiment of the utility model, by setting the heat-conducting component, the heat conduction path from the heat source of the LED beads to the elastic aluminum sheet is greatly optimized, and the thermal resistance between the heat source and the heat sink is significantly reduced, which is a key link to improve the overall heat dissipation efficiency.

[0047] Furthermore, the width of the mounting opening is smaller than the width of the cavity inside the housing. The bottom surface of the housing is provided with an aluminum sheet slot 71 around the mounting opening for engaging with the edge of the elastic aluminum sheet. The housing is provided with a locking member 72 for locking the elastic aluminum sheet in the aluminum sheet slot. The use of the aluminum sheet slot and the locking member improves the convenience, accuracy and long-term reliability of the installation of the elastic aluminum sheet, and also facilitates disassembly and maintenance.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
