Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED module technology, and in particular to an LED module with moisture-proof function. Background Technology
[0002] LED modules play an important role in modern life. They integrate multiple LED beads and related circuits to provide a stable light source for various scenarios. In the lighting field, they can efficiently and energy-savingly illuminate indoor and outdoor spaces such as streets, shopping malls, and offices. In display applications, by combining LED modules of different colors, clear and vivid images and text can be presented, and they are widely used in advertising, stage backgrounds, and other applications.
[0003] In the prior art, the utility model with announcement number CN220792975U provides an LED module with a moisture-proof function, including a bottom shell. Grooves are respectively formed on both sides of the inner side of the bottom shell, and a box is inserted into the groove. A desiccant packet is placed inside the box. A limiting component is installed on the rectangular top surface inside the bottom shell, and the LED module body is installed inside the bottom shell through four limiting components. The limiting component includes a rod and a limiting block. The rod is fixedly installed on the top inside the bottom shell. By using the bottom shell, rod, limiting block, groove, and limiting hole in cooperation, when disassembling and replacing the LED module body, the limiting block can be rotated to make it horizontal with the limiting hole. Moving the LED module body downwards allows the limiting block to extend out of the limiting hole, thus releasing the limiting block from restricting the LED module body.
[0004] This patent addresses the problem that when LED modules malfunction or are damaged, users need to remove each bolt one by one with screwdrivers or other tools to disassemble the LED module, which is cumbersome and poses certain safety hazards. By using a base shell, rod, and limiting blocks, the patent enables quick disassembly and installation of the LED module body, thereby achieving convenient maintenance and repair.
[0005] However, in actual use, the above-mentioned patent still has the following shortcomings: when the LED module is running, the heat dissipation of its internal components will aggravate the temperature change of the inner cavity of the protective shell, which will affect the normal operation of the desiccant placed inside the protective shell. As a result, the adsorption capacity of the desiccant will be significantly reduced at high temperatures, while at low temperatures, condensation will appear on the surface of the desiccant, which will increase the humidity inside the module. Therefore, this application provides an LED module with moisture-proof function to meet the requirements. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an LED module with moisture-proof function.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: an LED module with moisture-proof function, including a protective shell, a module body disposed in the inner cavity of the protective shell, and an adjustment component disposed on the side of the module body;
[0008] The adjustment assembly includes a support plate, a double metal plate on the top of the support plate, a small push rod on the side of the double metal plate, a rack fixedly connected to one end of the small push rod, a gear meshing on the side of the rack, a transmission rod fixedly connected to the top of the gear, and a baffle rotatably connected to the bottom of the transmission rod away from the gear.
[0009] In a preferred embodiment, a first limiting rod and a second limiting rod are rotatably connected to one end of the top of the baffle, and the ends of the first limiting rod and the second limiting rod away from the baffle are both rotatably connected to the bottom of the inner cavity of the protective shell.
[0010] The technical effect of adopting the above technical solution is that the movement trajectory of the baffle can be limited by the cooperation of the first limit rod and the second limit rod.
[0011] In a preferred embodiment, a drying component is provided on the side of the support plate. The drying component includes an isolation box, a placement box is slidably connected to the inner cavity of the isolation box, a first limiting block is fixedly connected to the side of the placement box, and a second limiting block is fixedly connected to the side of the isolation box.
[0012] The technical effect of adopting the above technical solution is that the bottom of the isolation box is slidably connected to the bottom of the inner cavity of the protective shell, and the inner cavity of the placement box is equipped with multiple sets of desiccant. Through the cooperation of the first limiting block and the second limiting block, the placement box can be quickly removed.
[0013] In a preferred embodiment, a fixing rod is fixedly connected to the side of the isolation box opposite to the module body, a connecting rod is rotatably connected to the side of the fixing rod, and an elastic sealing strip is fixedly connected to one end of the connecting rod.
[0014] The technical effects of adopting the above technical solution are: by setting a fixing rod, the connecting rod can be supported; and by setting an elastic sealing strip, the interior of the module body can be sealed to a certain extent.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] This invention features a support plate to support the rack and gear. A drive module is located at one end of a small push rod, and multiple ventilation slots are provided on both sides of the protective shell. At room temperature, the baffle is in a semi-open state. When the internal temperature of the protective shell rises, the double metal plates expand, activating the drive module. This causes the output end of the small push rod to move towards the center of the protective shell. When the small push rod moves, it drives the gear to rotate counterclockwise via the rack. The counterclockwise rotation of the gear drives the baffle via the transmission rod, thereby expanding the ventilation area of the vents and accelerating internal heat dissipation. To prevent excessively high internal temperatures from increasing the activity of water molecules in the air, which would make it more difficult for the desiccant to adsorb moisture, the double metal plates contract when the internal temperature of the protective shell decreases. This contraction causes the output end of the small push rod to retract, which in turn drives the gear to rotate clockwise via the rack. This clockwise rotation of the gear, in turn, drives the baffle to block the vents via the transmission rod, reducing the exchange of air between the inside and outside. This effectively maintains the internal temperature of the protective shell and prevents condensation on the outer surface of the desiccant due to excessively low temperatures.

[0025] 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.
[0026] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: an LED module with moisture-proof function, the LED module with moisture-proof function includes a protective shell 1, a module body 11 is provided in the inner cavity of the protective shell 1, and an adjustment component 2 is provided on the side of the module body 11;
[0027] The adjusting assembly 2 includes a support plate 21. A double-piece metal plate 22 is mounted on the top of the support plate 21. A small push rod 23 is mounted on the side of the double-piece metal plate 22. A rack 24 is fixedly connected to one end of the small push rod 23. A gear 25 meshes with the side of the rack 24. A transmission rod 26 is fixedly connected to the top of the gear 25. A baffle 27 is rotatably connected to the bottom of the transmission rod 26 away from the gear 25. A first limiting rod 28 and a second limiting rod 29 are rotatably connected to one end of the top of the baffle 27. The ends of the first limiting rod 28 and the second limiting rod 29 away from the baffle 27 are both rotatably connected to the protective housing. At the bottom of the inner cavity, a ventilation opening 210 is provided on the side of the support plate 21. The support plate 21 supports the rack 24 and gear 25. A drive module is provided at one end of the small push rod 23. Multiple ventilation slots are provided on both sides of the protective shell 1. Under normal temperature, the baffle 27 is in a semi-open state. When the internal temperature of the protective shell 1 rises, the double metal plates 22 expand, thereby activating the drive module. This causes the output end of the small push rod 23 to move towards the center of the protective shell 1. When the small push rod 23 moves, it can pass through the rack 24 drives gear 25 to rotate counterclockwise. When gear 25 rotates counterclockwise, it can drive baffle 27 to move through transmission rod 26, thereby expanding the ventilation area of vent 210 and accelerating internal heat dissipation. This prevents the activity of water molecules in the air from increasing due to excessive internal temperature, which would make it more difficult for the desiccant to adsorb moisture. Similarly, when the internal temperature of the protective shell 1 decreases, the double metal plates 22 contract, which causes the output end of the small push rod 23 to contract. When the output end of the small push rod 23 contracts, it can drive the baffle 27 to move through transmission rod 26. The gear 25 is driven to rotate clockwise by the gear 24. When the gear 25 rotates clockwise, it can drive the baffle 27 through the transmission rod 26 to block the vent 210, thereby reducing the exchange of air between the inside and outside. This can achieve the effect of heat preservation of the inner cavity of the protective shell 1, and avoid the problem of condensation on the outer surface of the desiccant due to excessively low temperature. When the baffle 27 moves, the first limit rod 28 and the second limit rod 29 cooperate to limit its movement trajectory, so as to prevent the baffle 27 from shifting its position during operation and causing damage.
[0028] Going further, such as Figure 2 - Figure 4As shown: A drying assembly 3 is provided on the side of the support plate 21. The drying assembly 3 includes an isolation box 31, a placement box 32 is slidably connected to the inner cavity of the isolation box 31, a first limiting block 33 is fixedly connected to the side of the placement box 32, a second limiting block 34 is fixedly connected to the side of the isolation box 31, a sliding groove 39 is provided on the side of the isolation box 31, and a sealing cover 38 is provided at one end of the isolation box 31. A support column 12 is fixedly connected to the inner cavity of the protective shell 1, and a groove 13 is provided on the side of the support column 12. Spring pieces are provided on the sides of the first limiting block 33 and the second limiting block 34. A handle is provided on the side of the sealing cover 38. The bottom of the isolation box 31 is slidably connected to the bottom of the inner cavity of the protective shell 1. Multiple sets of desiccant are placed in the inner cavity of the placement box 32. When the desiccant needs to be replaced, the handle is pulled to move the placement box 32 to the outside of the protective shell 1. When the placement box 32 moves, it can drive the first limiting block 33 to move along the inner cavity of the slide groove 39. When the placement box 32 moves to a certain position, the first limiting block 33 contacts the inner wall of the slide groove 39, thereby driving the isolation box 31 to move. When the isolation box 31 moves to a certain position, the side of the first limiting block 33 contacts the side of the second limiting block 34, thereby causing the first limiting block 33 to be compressed, thus achieving the effect of the placement box 32 separating from the isolation box 31. At the same time, one end of the second limiting block 34 engages with the inner cavity of the groove 13, thereby stopping the movement. Continue to pull the sealing cover 38, thereby removing the placement box 32, and then replacing the desiccant placed in the inner cavity of the placement box 32. This avoids the need to disassemble the entire module body 11 when replacing the desiccant, greatly improving the replacement efficiency.
[0029] When replacing the desiccant, during the removal process, it will inevitably come into contact with the elastic sealing strip 37 located on the side of the module body 11, which may cause damage and affect the sealing effect. Figure 4 As shown: In this solution, a fixing rod 35 is fixedly connected to the side of the isolation box 31 opposite to the module body 11. A connecting rod 36 is rotatably connected to the side of the fixing rod 35. An elastic sealing strip 37 is fixedly connected to one end of the connecting rod 36. When the placement box 32 moves the isolation box 31, the fixing rod 35 can drive the connecting rod 36 to fold, thereby achieving the effect of driving the elastic sealing strip 37 to move relative to each other. This avoids frictional contact between the placement box 32 and the elastic sealing strip 37 during the removal of the placement box 32, which could cause damage and affect the sealing effect. Similarly, after the desiccant is replaced, the placement box 32 is pushed back into the cavity of the isolation box 31. When the placement box 32 moves to a certain position, it can drive the isolation box 31 to move, thereby achieving the effect of driving the connecting rod 36 to fold towards the middle of the fixing rod 35 through the fixing rod 35. When the connecting rod 36 retracts, it can drive the elastic sealing strip 37 to close.
[0030] Working principle:
[0031] like Figure 1-4 As shown:
[0032] In use: After the module body 11 is installed, at room temperature, the baffle 27 is in a semi-open state. When the internal temperature of the protective shell 1 rises, the double metal pieces 22 expand, thereby activating the drive module located on the side of the small push rod 23. This causes the output end of the small push rod 23 to move towards the center of the protective shell 1. When the small push rod 23 moves, it drives the gear 25 to rotate counterclockwise via the rack 24. When the gear 25 rotates counterclockwise, it drives the baffle 27 to move via the transmission rod 26, thereby expanding the ventilation area of the vent 210. Similarly, when the internal temperature of the protective shell 1 decreases, the double metal pieces 22 contract, causing the output end of the small push rod 23 to contract. When the output end of the small push rod 23 contracts, it drives the gear 25 to rotate clockwise via the rack 24. When the gear 25 rotates clockwise, it drives the baffle 27 to block the vent 210 via the transmission rod 26. This reduces the exchange of air between the inside and outside, thus achieving the effect of heat preservation of the inner cavity of the protective shell 1. When the desiccant needs to be replaced, by pulling the handle set on the side of the sealing cover 38, the placement box 32 can be moved to the outside of the protective shell 1. When the placement box 32 moves, it can drive the first limiting block 33 to move along the inner cavity of the slide groove 39. When the placement box 32 moves to a certain position, the first limiting block 33 contacts the inner wall of the slide groove 39, thereby driving the isolation box 31 to move. When the isolation box 31 moves to a certain position, the side of the first limiting block 33 contacts the side of the second limiting block 34, thereby causing the first limiting block 33 to be compressed, thereby achieving the effect of the placement box 32 detaching from the isolation box 31. At the same time, one end of the second limiting block 34 engages with the inner cavity of the groove 13, thereby stopping the movement. Continue to pull the sealing cover 38, thereby removing the placement box 32, and then the desiccant placed in the inner cavity of the placement box 32 can be replaced.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
