Description

Technical Field

[0001] This utility model relates to the field of LED light board technology, specifically to a staggered heat dissipation structure for LED light boards. Background Technology

[0002] The heat dissipation problem of LED light boards has always been one of the key factors limiting their performance and lifespan. LED beads generate a lot of heat during operation. If this heat cannot be dissipated effectively, it will cause the beads to overheat, thereby reducing luminous efficacy and even shortening the lifespan. Therefore, how to improve the heat dissipation efficiency of LED light boards has become an important issue in the development of LED technology.

[0003] As disclosed in CN223271139U, an LED chip arrangement structure with high heat dissipation includes a substrate and several LED chips mounted on the substrate. The LED chips are arranged in at least two rows, with adjacent rows staggered to form a triangular structure between three adjacent LED chips. This arrangement structure, through staggered placement, achieves a triangular arrangement, increasing the distance between adjacent LED chips. This expands the heat dissipation medium area of ​​the LED chips, thereby reducing heat flux density, decreasing thermal resistance, enhancing heat transfer and outward heat radiation capabilities, improving heat dissipation, and extending the lifespan of the LED chips.

[0004] While the aforementioned patent can achieve basic heat dissipation to a certain extent, it still has some shortcomings. First, the design does not have a dedicated heat dissipation structure and relies entirely on natural heat dissipation, which limits its heat dissipation efficiency. Under high-power operation or long-term use, natural heat dissipation alone is insufficient to meet the thermal management requirements of LED beads, leading to excessively high local temperatures, which in turn affects the lifespan and performance of the beads. In addition, the patent design lacks convenient disassembly functionality. If repair, replacement, or maintenance is required, the lack of a disassembly design not only increases the complexity of maintenance but also leads to the risk of damage during disassembly, thereby affecting the long-term use and maintenance costs of the equipment.

[0016] As attached Figure 1 To be continued Figure 5 As shown: This embodiment provides a staggered arrangement heat dissipation structure for an LED light board, including a substrate 1. A plurality of LED beads 2 are fixedly connected to the top surface of the substrate 1, and the plurality of LED beads 2 are arranged in a staggered and equidistant manner. A heat dissipation groove 3 is formed on the bottom surface of the substrate 1. The heat dissipation groove 3 is located below the center line between two adjacent rows of LED beads 2, and the heat dissipation groove 3 is parallel to the LED beads 2. A fixing shell 4 is fixedly connected to the bottom surface of the substrate 1. A heat dissipation tooth 5 is provided on the surface of the fixing shell 4. A fan 6 is fixedly connected to the center of the heat dissipation tooth 5. Two locking blocks 7 are fixedly connected to both sides of the surface of the heat dissipation tooth 5. A first locking groove 8 is formed on one side of the locking block 7. Two second locking grooves 9 are formed on both sides of the fixing shell 4. Two first springs 10 are fixedly connected to the inner cavity of the second locking groove 9. One end of the two first springs 10 is fixedly connected to a connecting plate 11, and one side of the connecting plate 11 is in contact with the locking block 7. A locking mechanism 12 is provided in the inner cavity of both sides of the fixing shell 4. One end of the locking mechanism 12 is slidably connected to the inner cavity of the first locking groove 8.

[0017] Specifically, the snap-fit ​​mechanism 12 includes a limiting post 121 that is slidably connected to the inner cavity of the first snap-fit ​​groove 8. One end of the limiting post 121 is fixedly connected to a slide rod 122. A second spring 123 is sleeved on the surface of the slide rod 122. The second spring 123 is fixedly connected to the inner cavity of the fixed shell 4. One end of the slide rod 122 extends through to the outer side of the fixed shell 4 and is fixedly connected to a pull rod 124.

[0018] In this embodiment, the snap-fit ​​mechanism 12 achieves the snap-fit ​​fixing function. By pulling the pull rod 124, the limiting post 121 can be disengaged from the inner cavity of the first slot 8, thereby releasing the fixed relationship between the snap-fit ​​block 7 and the first slot 8. This effectively eliminates the constraint of the snap-fit ​​structure, allowing the connection between the snap-fit ​​block 7 and the first slot 8 to be easily released, which greatly facilitates subsequent disassembly, making it convenient for maintenance, repair or replacement. This simplifies the operation process of the equipment, improves maintenance efficiency, and reduces the time and cost losses caused by inconvenient disassembly operations.

[0019] Specifically, a thermal pad 13 is fixedly connected to the bottom surface of the substrate 1, and the surface of the thermal pad 13 is in contact with the heat dissipation teeth 5.

[0020] In this embodiment: By setting the thermal pad 13, the thermal pad 13 is precisely placed at the connection between the substrate 1 and the heat dissipation tooth 5, which effectively improves the heat conduction efficiency. By reducing thermal resistance, the thermal pad 13 ensures that heat can be transferred quickly and evenly from the substrate 1 to the heat dissipation tooth 5, avoiding the accumulation of heat in the connection area between the substrate 1 and the heat dissipation tooth 5, thereby extending the service life of the substrate 1 and the lamp bead 2, and ensuring long-term stability and high efficiency performance.

[0021] Specifically, the surface of the heat dissipation fins 5 is connected to the base plate 14, one side of the fan 6 is located in the inner cavity at the center of the base plate 14, and a protective pad 15 is fixedly connected to the surface of the base plate 14.

[0022] In this embodiment, the base plate 14 mainly serves to protect and safeguard the heat dissipation teeth 5. The base plate 14 effectively blocks the direct contact between the heat dissipation teeth 5 and the outside world, reducing the risk of the heat dissipation teeth 5 being subjected to external impact or mechanical damage during use. The heat dissipation teeth 5 can remain intact, avoiding performance degradation or structural damage caused by improper contact. The protective pad 15 not only effectively protects the heat dissipation teeth 5 and the base plate 14 from external physical damage, but also enhances the stability of the fixed connection by increasing friction.

[0023] Specifically, two fixing blocks 16 are fixedly connected to both sides of the base plate 14, and bolts 17 are threadedly connected to the inner cavity of the fixing blocks 16.

[0024] In this embodiment, the use of fixing block 16 and bolt 17 together ensures the stable installation of the device, preventing the substrate 1 and lamp bead 2 from loosening or shaking during use, thus ensuring the stability and safety of the device during operation.

[0025] The working principle and usage process of this utility model: The LED beads 2 are fixedly connected to the top of the substrate 1 in a staggered and equidistant arrangement. The staggered arrangement can increase the distance between adjacent LED beads 2 and reduce heat accumulation. The heat is transferred downward through the substrate 1 to the heat dissipation groove 3 area. The heat dissipation groove 3 is set below the center line of two adjacent rows of LED beads 2, forming a heat conduction channel parallel to the arrangement direction of the LED beads 2. With the help of the heat conduction pad 13, the heat is efficiently conducted to the heat dissipation teeth 5. The heat dissipation teeth 5 can increase the heat dissipation area. With the action of the fan 6, the air flow is forcibly accelerated. The cold air enters through the gap of the heat dissipation teeth 5, absorbs heat, and is discharged from both sides of the fixed shell 4, forming a directional heat dissipation air channel. The base plate 14 is fixedly connected to the bottom of the heat dissipation teeth 5. The protective pad 15 prevents mechanical damage. At the same time, the inner cavity of the base plate 14 provides structural support for the fan 6. When it is necessary to install the heat dissipation teeth 5 and the fan 6, the heat dissipation teeth 5 are... The two side locking blocks 7 are inserted into the second locking slot 9 of the fixed shell 4. The locking blocks 7 press the connecting plate 11, causing the connecting plate 11 to compress the first spring 10 in the second locking slot 9. When the locking blocks 7 are fully inserted, under the elastic recovery of the second spring 123, the limiting post 121 is driven to slide into the first locking slot 8 opened on the surface of the locking blocks 7, thereby achieving the lateral fixation of the locking blocks 7 and ensuring that the heat dissipation teeth 5 and the heat-conducting pad 13 are always in close contact. At the same time, the heat dissipation teeth 5 and the fan 6 are fixedly installed. When disassembling and maintaining, the pull rod 124 on the outside of the fixed shell 4 is pulled. The pull rod 124 drives the slide rod 122 to compress the second spring 123, causing the limiting post 121 to disengage from the first locking slot 8. At this time, under the elastic recovery of the first spring 10, the connecting plate 11 is driven to lift the locking blocks 7, thereby disassembling and separating the heat dissipation teeth 5 and the fan 6 for replacement or repair.

[0026] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

Therefore, the scope of protection of this invention shall be determined by the claims.
