Description

Technical Field

[0001] This utility model relates to the field of LED modules, and in particular to a waterproof and dustproof LED module. Background Technology

[0002] An LED module is a device that integrates several LEDs, a driver circuit, a heat dissipation structure, and necessary connection terminals into a compact assembly. It is typically encapsulated on a steel plate, aluminum substrate, or plastic substrate and can be directly mounted onto lighting fixtures or equipment. Its working principle involves the driver circuit converting power (such as direct current) into a stable operating current to drive the LEDs to emit light, and a heat dissipation system maintaining a suitable temperature, thereby achieving stable brightness and a long lifespan.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Conventional LED modules typically lack heat dissipation devices. If the heat generated by the LED during illumination cannot be dissipated quickly and evenly, the operating temperature can easily rise. Increased temperature accelerates light decay, reduces luminous efficiency, and shortens the LED's lifespan. Furthermore, existing heat dissipation devices often allow external moisture, dust, and other contaminants to accumulate on the heat dissipation surface, reducing heat conduction efficiency. Moreover, the intrusion of moisture and dust not only affects heat dissipation but may also pose a risk of short circuits or corrosion to the circuitry and connection terminals.

[0004] Therefore, those skilled in the art have provided a waterproof and dustproof LED module to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterproof and dustproof LED module. The sealing plate is fixed above the transparent lampshade to form a waterproof and sealed structure for the outer shell, preventing external water from entering the interior of the outer shell and thus reducing the risk of moisture affecting the LED light panel.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A waterproof and dustproof LED module includes a housing, a partition fixedly disposed in the middle of the interior of the housing, an air outlet duct opened at the lower end of the partition, an LED light board fixedly disposed at the upper end of the partition, fixing rings fixedly disposed on both sides of the lower end of the partition, fixing brackets fixedly disposed on the upper inner side of the two fixing rings, a motor fixedly disposed at the lower end of each of the two fixing brackets, fan blades fixedly sleeved at the output ends of the two motors, and an air inlet mesh fixedly disposed at the lower end of the housing. A transparent lampshade is fixedly installed on the upper end of the outer shell. A sealing plate is fixedly installed on the upper edge of the transparent lampshade. Fixing plates are fixedly installed on both sides of the inner end of the transparent lampshade. Support columns are fixedly installed on the lower ends of the two fixing plates. Pressure plates are fixedly installed on the lower ends of the two support columns.

[0007] Furthermore, the two fan blades are rotatably mounted at the lower end of the partition, and the air inlet screen is mounted at the lower end of the two fixed rings.

[0008] Furthermore, the sealing plate is positioned above the outer casing at its edge, and mounting grooves are provided at the lower edges of the outer casing near both sides.

[0009] Furthermore, the transparent lampshade is positioned above the LED light panel, and the lower part of the pressure plate contacts the upper part of the LED light panel.

[0010] Furthermore, the two fan blades are positioned below the LED light panel, and the two motors are positioned above the air intake grille.

[0011] Furthermore, the two support columns are located inside the outer casing, and the lower end of the air inlet mesh has multiple through slots.

[0012] This utility model has the following beneficial effects: 1. This utility model proposes a waterproof and dustproof LED module. A transparent lampshade is fixed to the top of the outer casing with bolts, and a pressure plate presses the LED light board firmly, effectively preventing displacement of the LED light board within the casing. A sealing plate is then fixed above the transparent lampshade, forming a waterproof and sealed structure that prevents external water from entering the casing and reduces the risk of moisture affecting the LED light board. After the motor is started, two fan blades rotate, drawing in air from below the air intake grille and delivering it to below the partition, effectively increasing the air convection intensity below the LED light board, promoting rapid heat dissipation, and improving the stability of the light board's operation.

[0015] 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.

[0016] Reference Figures 1-8 One embodiment provided by this utility model: A waterproof and dustproof LED module includes a housing 1. A partition 2 is fixedly installed in the middle of the interior of the housing 1. An air outlet 14 is opened at the lower end of the partition 2. An LED light panel 3 is fixedly installed at the upper end of the partition 2. Fixing rings 4 are fixedly installed on both sides of the lower end of the partition 2. Fixing brackets 5 are fixedly installed on the upper inner sides of the two fixing rings 4. Motors 6 are fixedly installed at the lower ends of both fixing brackets 5. Fan blades 7 are fixedly fitted onto the output ends of the two motors 6. An air inlet mesh 8 is fixedly installed at the lower end of the housing 1. A transparent lampshade 9 is fixedly installed at the upper end of the edge of the transparent lampshade 9. A sealing plate 10 is fixedly installed on the upper edge of the transparent lampshade 9. Fixing brackets 10 are fixedly installed on both sides of the inner end of the transparent lampshade 9. The fixed plate 11 has two support columns 12 fixedly installed at the lower ends of each fixed plate 11. The pressure plate 13 is fixedly installed at the lower ends of the two support columns 12. The two fan blades 7 are rotatably installed at the lower ends of the partition plate 2. The air inlet mesh 8 is installed at the lower ends of the two fixed rings 4. The edge of the sealing plate 10 is located above the outer shell 1. The lower end of the outer shell 1 has mounting grooves on both sides. The transparent lamp cover 9 is located above the LED light panel 3. The lower part of the pressure plate 13 contacts the upper part of the LED light panel 3. The two fan blades 7 are located below the LED light panel 3. The two motors 6 are located above the air inlet mesh 8. The two support columns 12 are located inside the outer shell 1. The lower end of the air inlet mesh 8 has multiple through grooves.

[0017] Specifically, when sealing the top of the LED light panel 3, the transparent lamp cover 9 is first fixed to the top of the outer shell 1 with bolts. The pressure plate 13 presses down on the top of the LED light panel 3, and the support column 12 is at the same height as the partition 2. This can effectively prevent the LED light panel 3 from shifting inside the outer shell 1, thereby improving the stability and safety of the LED light panel 3. The sealing plate 10 is fastened to the top of the transparent lamp cover 9 to form a waterproof barrier, preventing external water from entering the interior of the outer shell 1 and reducing the risk of moisture affecting the LED light panel 3. When cooling the LED light panel 3, the motor 6 is started and the two fan blades 7 begin to rotate, drawing in air below the air intake mesh 8 and delivering it to the area below the partition 2, and finally expelling it from the air outlet 14, thereby enhancing the air convection below the LED light panel 3, promoting rapid heat dissipation, and improving the thermal management effect. It is important to note that the motor 6 should be a waterproof motor 6, so that even if water flows into the air inlet mesh 8, it will not affect its normal operation, thus improving the reliability and safety of the system in humid environments. At the same time, the air inlet mesh 8 uses a dustproof mesh, which can block dust from entering the system and reduce dust contamination of the motor 6 and the heat dissipation channel.

[0018] Working principle: When sealing the top of the LED light panel 3, the transparent lampshade 9 is first fixed to the top of the outer casing 1 with bolts. The pressure plate 13 presses down on the top of the LED light panel 3, and the support column 12 is at the same height as the partition 2 to ensure that the LED light panel 3 will not shift. Then, the sealing plate 10 is fixed above the transparent lampshade 9 to prevent external water from entering the interior of the outer casing 1 and to avoid water flow affecting the LED light panel 3. When cooling the LED light panel 3, the motor 6 is started, and the two fan blades 7 begin to rotate. The fan blades 7 draw in air below the air inlet mesh 8 and send the air to the bottom of the partition 2 for cooling, ensuring that the LED light panel 3 can be cooled quickly.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
