Abstract
Description
Technical Field
[0001] This invention relates to the field of LED power supply technology, and in particular to a high-efficiency dustproof LED power supply. Background Technology
[0002] As a core component of lighting equipment, the stability and lifespan of LED power supplies are directly affected by the working environment. In outdoor or industrial environments, there are many suspended dust particles in the air. To ensure the heat dissipation efficiency of LED power supplies, ventilation holes or cooling fans are usually required on the power supply casing. However, this design makes it very easy for external dust to enter the power supply with the airflow.
[0003] Existing LED power supplies typically address the conflict between heat dissipation and dust prevention by using a single dust filter to cover the air inlet or outlet. However, this structure has significant shortcomings in practical use: firstly, the dust prevention effect of a single-layer dust filter is poor; while heat dissipation is being carried out, dust can still pass through the single-layer dust filter, thus affecting the working efficiency and lifespan of the LED power supply; secondly, even when the power supply is not in operation, external dust can still slowly seep in through unsealed vents, leading to dust accumulation on internal components and increasing the risk of short circuits or overheating.
[0004] Furthermore, the installation structure of existing LED power supplies is usually quite simple, and the power supply unit is prone to shaking or even being bumped during transportation or movement, affecting the stability of the internal circuitry. At the same time, installation or disassembly is relatively difficult, resulting in insufficient convenience for maintenance.
[0005] Therefore, a high-efficiency, dustproof LED power supply is provided to solve the above-mentioned technical problems. Summary of the Invention
[0006] The purpose of this invention is to provide a highly efficient dustproof LED power supply to address the shortcomings of existing technologies, thereby solving the technical problems of poor dustproof performance of existing LED power supplies while dissipating heat and the susceptibility of the power supply body to impacts during transportation or movement.
[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A high-efficiency dustproof LED power supply includes a dustproof frame with an opening on the side and an LED power supply body installed in the dustproof frame. It also includes a frame cover for covering the side opening of the dustproof frame. Limiting components for limiting the LED power supply body are installed on the left and right side walls inside the dustproof frame. Clamping components for clamping the LED power supply body are installed on the upper and lower side walls inside the dustproof frame. The dustproof frame has an extension frame on the side away from the frame cover. The extension frame is equipped with several cooling fans for blowing cool air to the LED power supply body. Multiple first dustproof nets are installed on both the side of the cooling fans near the LED power supply body and the side away from the LED power supply body. The multiple first dustproof nets are spaced apart. Multiple exhaust ports are formed on the top and bottom of the dustproof frame. Multiple stacked second dustproof nets are installed at each exhaust port.
[0008] Furthermore, the frame cover is snapped into place with the dustproof frame.
[0009] Furthermore, the side of the frame cover near the dustproof frame body has an insert for embedding into the dustproof frame body. The top and bottom edges of the insert are each formed with a pair of locking rods. The top and bottom of the dustproof frame body are each formed with a pair of locking slots. The ends of each locking rod away from the frame cover are each formed with a buckle. When the frame cover covers the side opening of the dustproof frame body, the buckles on the ends of each locking rod are respectively engaged into different locking slots.
[0010] Furthermore, the top and bottom walls inside the dustproof frame are each formed with a pair of guide grooves, each guide groove being aligned with a different slot and used to guide the buckle.
[0011] Furthermore, a window for the LED power supply body to pass through is formed in the middle of the frame cover, and an elastic sealing part for interference fit with the outer side wall of the LED power supply body is provided at the window of the frame cover. The elastic sealing part is annular.
[0012] Furthermore, the limiting components on the left and right side walls are arranged symmetrically, and the clamping components on the upper and lower side walls are arranged symmetrically.
[0013] Furthermore, the clamping assembly includes a second connecting plate and a plurality of second guide posts fixed to the inner wall of the dustproof frame. The second guide posts are arranged vertically, and the second connecting plate is slidably connected to the plurality of second guide posts. It also includes a clamping plate for contacting the surface of the LED power supply body to clamp it. The edge of the second connecting plate is formed with a connecting part that is fixedly connected to the edge of the clamping plate. A second spring is wound around each second guide post. The second spring is placed between the inner wall of the dustproof frame and the second connecting plate and is used to apply a pushing force to the second connecting plate. The end of the clamping plate near the side opening of the dustproof frame is formed with a first guide lip plate for guiding the LED power supply body. The first guide lip plate is arranged at an angle.
[0014] Furthermore, the clamping assembly also includes multiple fixing frames that are fixedly connected to the second connecting plate. Each fixing frame is provided with multiple vertically arranged third guide posts, and each fixing frame is provided with a connecting rod that is slidably connected to the third guide posts. Each third guide post is wound with a third spring, and the third spring is placed on the side of the connecting rod near the clamping plate. It also includes a pair of pressure plates, which are respectively placed on the left and right sides of the fixed frame and are simultaneously fixedly connected to the connecting rods on each fixed frame; each pressure plate has a second guide lip plate formed at the end near the side opening of the dustproof frame, the second guide lip plate is arranged at an angle, and each lever is equipped with a top block for sliding on the surface of the second guide lip plate and the surface of the pressure plate on the side near the LED power supply body.
[0015] Furthermore, the clamping plate has multiple heat dissipation holes.
[0016] Furthermore, the limiting component includes a connecting frame and a plurality of first guide posts fixedly disposed on the inner sidewall of the dustproof frame. The first guide posts are arranged laterally and their length direction is perpendicular to the installation direction of the LED power supply body. The connecting frame is equipped with a first connecting plate, which is laterally slidably connected to the plurality of first guide posts. Each first guide post is wound with a first spring, which is placed between the inner sidewall of the dustproof frame and the first connecting plate and is used to apply a pushing force to the first connecting plate. The connecting frame is rotatably provided with a plurality of rollers for contacting the surface of the LED power supply body. The plurality of rollers are arranged in an array along the installation direction of the LED power supply body, and the axis of rotation of the rollers is arranged vertically.
[0017] The beneficial effects of this invention are as follows: After the LED power supply body is inserted into the dustproof frame through the side opening, it is clamped by two clamping components arranged vertically. At the same time, two limiting components arranged horizontally limit the LED power supply body. With the cooperation of the clamping components and the limiting components, the LED power supply body can be stably installed inside the dustproof frame. When the LED power supply is taken out, it is prevented from moving around inside the dustproof frame and causing bumps. After the LED power supply body is installed inside the dustproof frame, the frame cover is placed on the side opening of the dustproof frame to cover it.
[0018] When using this LED power supply, multiple cooling fans blow cool air onto the LED power supply body, expelling the heat generated by the LED power supply body through the exhaust ports. During the heat dissipation process, multiple spaced-apart first dustproof meshes filter the air passing through the cooling fans, removing dust from the air and preventing external dust from entering the dustproof frame and adhering to the LED power supply body, thus improving the dustproof effect. Furthermore, by installing multiple stacked second dustproof meshes at each exhaust port, external dust cannot enter the dustproof frame when the LED power supply is not in use. The combined effect of the first and second dustproof meshes allows the dustproof frame to effectively protect the LED power supply body from dust. In addition, the multiple spaced-apart first dustproof meshes and the multiple stacked second dustproof meshes achieve multiple filtrations of the air, further improving the dustproof effect and achieving highly efficient dust prevention.

[0026] The following is a detailed description of a high-efficiency dustproof LED power supply according to the present invention, with reference to the accompanying drawings.
[0027] like Figure 1-2As shown, an embodiment of the present invention for a high-efficiency dustproof LED power supply includes a dustproof frame 1 and an LED power supply body 2 installed inside the dustproof frame 1. The LED power supply body 2 can be inserted into the dustproof frame 1 through a side opening. The embodiment also includes a frame cover 3 for covering the side opening of the dustproof frame 1. Limiting components 4 for limiting the LED power supply body 2 are installed on the left and right side walls inside the dustproof frame 1. Clamping components 5 for clamping the LED power supply body 2 are installed on the upper and lower side walls inside the dustproof frame 1. The limiting components 4 on the left and right side walls are arranged symmetrically from left to right, and the clamping components 5 on the upper and lower side walls are arranged symmetrically from top to bottom.
[0028] After the LED power supply body 2 is inserted into the dustproof frame 1 through the side opening, it is clamped by two clamping components 5 arranged vertically. At the same time, two limiting components 4 arranged horizontally limit the LED power supply body 2. With the cooperation of the clamping components 5 and the limiting components 4, the LED power supply body 2 can be stably installed inside the dustproof frame 1. When the LED power supply is removed, it is prevented from moving around inside the dustproof frame 1 and causing bumps. After the LED power supply body 2 is installed inside the dustproof frame 1, the frame cover 3 is placed on the side opening of the dustproof frame 1 to cover it. Under the dustproof function of the dustproof frame 1, external dust can be effectively prevented from entering the dustproof frame 1 and affecting the use of the LED power supply body 2.
[0029] During use, the LED power supply body 2 generates heat. In order to achieve heat dissipation while protecting the LED power supply body 2 from dust, the dustproof frame 1 is provided with an extension frame 13 on the side of the dustproof frame 1 away from the frame cover 3. The extension frame 13 is equipped with several cooling fans 14 for blowing cool air to the LED power supply body 2. Multiple first dustproof nets 15 are installed on both the side of the cooling fans 14 close to the LED power supply body 2 and the side away from the LED power supply body 2, and the multiple first dustproof nets 15 are distributed at intervals. Multiple exhaust ports 16 are formed on the top and bottom of the dustproof frame 1, and multiple stacked second dustproof nets 17 are installed at each exhaust port 16.
[0030] When using this LED power supply, multiple cooling fans 14 are operated to blow cool air onto the LED power supply body 2, expelling the heat emitted by the LED power supply body 2 through the exhaust ports 16. During the heat dissipation process, multiple spaced first dustproof nets 15 filter the air passing through the cooling fans 14, removing dust from the air and preventing external dust from entering the dustproof frame 1 and adhering to the LED power supply body 2, thus improving the dustproof effect. Furthermore, by installing multiple stacked second dustproof nets 17 at each exhaust port 16, external dust cannot enter the dustproof frame 1 through the exhaust ports 16 when the LED power supply is not in use. The combined effect of the first dustproof nets 15 and the second dustproof nets 17 allows the dustproof frame 1 to effectively protect the LED power supply body 2 from dust. In addition, by setting multiple spaced first dustproof nets 15 and multiple stacked second dustproof nets 17, the air is filtered multiple times, further improving the dustproof effect and achieving highly efficient dust prevention.
[0031] In this embodiment, the frame cover 3 is snapped into the dustproof frame 1. Specifically, the side of the frame cover 3 closest to the dustproof frame 1 is formed with an insert 31 for embedding into the dustproof frame 1. The top and bottom edges of the insert 31 are each formed with a pair of locking rods 33. The top and bottom of the dustproof frame 1 are each formed with a pair of locking grooves 11. The ends of each locking rod 33 away from the frame cover 3 are each formed with a buckle 34. When the frame cover 3 covers the side opening of the dustproof frame 1, the buckles 34 on the ends of each locking rod 33 are respectively snapped into different locking grooves 11. The lever 33 is made of elastic plastic. When the lever 33 enters the interior of the dustproof frame 1, the buckle 34 presses against the inner wall of the dustproof frame 1, and the lever 33 will undergo elastic deformation. When the buckle 34 moves to align with the slot 11, under the elastic action of the lever 33, the buckle 34 is engaged in the corresponding slot 11. When it is necessary to remove the frame cover 3, the buckles 34 inside the slot 11 are pushed out using a specific tool. After all the buckles 34 are pushed out, a force is applied to the frame cover 3 away from the dustproof frame 1 to remove the frame cover 3 from the dustproof frame 1.
[0032] Additionally, a window for the LED power supply body 2 to pass through is formed in the middle of the frame cover 3. The window of the frame cover 3 has an elastic sealing part 32 for interference fit with the outer wall of the LED power supply body 2. The elastic sealing part 32 is annular and can be a silicone ring. When the frame cover 3 covers the opening of the dustproof frame 1, the wiring portion of the LED power supply body 2 passes through the window of the frame cover 3 and is placed on the outside of the dustproof frame 1, while the remaining portion of the LED power supply body 2 is placed inside the dustproof frame 1. As the LED power supply body 2 passes through the window, the annular elastic sealing part 32 interferes with the outer wall of the LED power supply body 2, filling the gap between the frame cover 3 and the LED power supply body 2, achieving a sealing effect and preventing dust from entering through the gap. By providing the elastic sealing part 32, the frame cover 3 can accommodate LED power supply bodies 2 of different sizes.
[0033] A pair of guide grooves 12 are formed on the top and bottom walls inside the dustproof frame 1. Each guide groove 12 is aligned with a different slot 11 and is used to guide the buckle 34. After the locking rod 33 enters the interior of the dustproof frame 1, the buckle 34 is placed in the guide groove 12 and guided by the guide groove 12 so that the buckle 34 can be accurately locked into the corresponding slot 11.
[0034] like Figure 3 Therefore, the limiting component 4 includes a connecting frame 41 and a plurality of first guide posts 42 fixedly disposed on the inner sidewall of the dustproof frame 1. The first guide posts 42 are arranged laterally and their length direction is perpendicular to the installation direction of the LED power supply body 2. The connecting frame 41 is provided with a first connecting plate 43, which is laterally slidably connected to the plurality of first guide posts 42. Each first guide post 42 is wound with a first spring 44, which is placed between the inner sidewall of the dustproof frame 1 and the first connecting plate 43 and is used to apply a pushing force to the first connecting plate 43. The connecting frame 41 is rotatably provided with a plurality of rollers 45 for contacting the surface of the LED power supply body 2. The plurality of rollers 45 are arranged in an array along the installation direction of the LED power supply body 2, and the axis of rotation of the rollers 45 is arranged vertically.
[0035] During the process of horizontally inserting the LED power supply body 2 into the dustproof frame 1, the surface of the LED power supply body 2 will contact the rollers 45, and multiple rollers 45 will roll on the surface of the LED power supply body 2 to reduce friction during insertion. After the LED power supply body 2 is inserted into the dustproof frame 1, the first spring 44 will be compressed, thereby applying force to the rollers 45. The rollers 45 on both sides apply relative forces to the LED power supply body 2, thereby limiting the LED power supply body 2. The first connecting plate 43 is laterally slidably connected to multiple first guide posts 42, thereby limiting the LED power supply body 2 of different sizes.
[0036] like Figure 4-5 Therefore, the clamping assembly 5 includes a second connecting plate 52 and a plurality of second guide posts 51 fixed to the inner wall of the dustproof frame 1. The second guide posts 51 are arranged vertically, and the second connecting plate 52 is slidably connected to the plurality of second guide posts 51. It also includes a clamping plate 54 for contacting the surface of the LED power supply body 2 to clamp it. The edge of the second connecting plate 52 is formed with a connecting part 55 that is fixedly connected to the edge of the clamping plate 54. A second spring 53 is wound around each second guide post 51. The second spring 53 is placed between the inner wall of the dustproof frame 1 and the second connecting plate 52 and is used to apply a pushing force to the second connecting plate 52.
[0037] A first guide lip 56 is formed at the end of the clamping plate 54 near the side opening of the dustproof frame 1 to guide the LED power supply body 2. The first guide lip 56 is arranged at an angle. Before the LED power supply body 2 is installed into the dustproof frame 1, the LED power supply body 2 will first contact the inclined first guide lip 56 to guide it. The LED power supply body 2 slides on the surface of the first guide lip 56. Because the first guide lip 56 is arranged at an angle, the clamping plate 54 will automatically move to contact the surface of the LED power supply body 2 (when the LED power supply body 2 is not installed, the distance between the two clamping plates 54 arranged vertically is less than the height of the LED power supply body 2). At this time, the second spring 53 is compressed and applies a force to the clamping plate 54 in the direction of the LED power supply body 2. The two clamping plates 54 apply relative forces to the LED power supply body 2, thereby clamping the LED power supply body 2 installed in the dustproof frame 1.
[0038] In addition, the clamping plate 54 is formed with multiple heat dissipation holes 541. By providing multiple heat dissipation holes 541, the contact area between the clamping plate 54 and the outer surface of the LED power supply body 2 is reduced, thereby improving the heat dissipation effect of the LED power supply body 2.
[0039] In this embodiment, the clamping assembly 5 further includes a plurality of fixing frames 57 fixedly connected to the second connecting plate 52. Each fixing frame 57 is provided with a plurality of vertically arranged third guide posts 58. Each fixing frame 57 is provided with a connecting rod 59 that is slidably connected to the third guide posts 58. A third spring 510 is wound around each third guide post 58. The third spring 510 is placed on the side of the connecting rod 59 near the clamping plate 54.
[0040] The clamping assembly 5 also includes a pair of pressure plates 511, which are respectively placed on the left and right sides of the fixed frame 57 and are fixedly connected to the connecting rods 59 on each fixed frame 57. Each pressure plate 511 has a second guide lip plate 512 formed at the end near the side opening of the dustproof frame 1. The second guide lip plate 512 is arranged at an angle. Each clamping rod 33 is equipped with a top block 35 for sliding on the surface of the second guide lip plate 512 and the surface of the pressure plate 511 on the side near the LED power supply body 2.
[0041] After the LED power supply body 2 is installed into the dustproof frame 1 and clamped by the two upper and lower clamping plates 54, the frame cover 3 can be snapped into place at the side opening of the LED power supply body 2. During the installation of the frame cover 3, the locking rod 33 first enters the interior of the dustproof frame 1, causing each buckle 34 to move laterally in different guide grooves 12. At the same time, each top block 35 slides on different surfaces of the second guide lip plate 512. Because the second guide lip plate 512 is inclined, when the locking rod 33 moves laterally with the top block 35, it pushes the pressure plate 511 and the second guide lip plate 512 toward the LED power supply body 2, compressing the third spring 510. When the buckle 34 engages... As the top block 35 slides from the surface of the second guide lip plate 512 to the surface of the pressure plate 511, the compressed third spring 510 applies a pushing force toward the LED power supply body 2 to the fixing frame 57, thereby applying a pushing force toward the LED power supply body 2 to the second connecting plate 52 and the clamping plate 54. When the clamping plate 54 clamps the LED power supply body 2, the compressed second spring 53 also applies a pushing force toward the LED power supply body 2 to the second connecting plate 52. Under the combined action of compressing the second spring 53 and the third spring 510, the clamping force of the clamping plate 54 on the LED power supply body 2 is greater, and it is more stable after being clamped, which improves the clamping effect of the clamping plate 54 and avoids loosening.
[0042] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.
[0043] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
