Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lighting fixtures, and more specifically, to a pressure-resistant LED underwater light. Background Technology
[0002] In the grand blueprint of building a maritime power, the development of marine resources is a crucial link, and the importance of underwater lighting cannot be underestimated. Natural light is scarce in deep-sea areas, making underwater operations highly dependent on lighting equipment.
[0003] Traditional underwater lights do not have dedicated protection for the power supply in the entire light to prevent the risk of short circuits after impact. The external structure is often designed with multiple nested layers, while the internal structure only focuses on the accumulation of components and ignores the design of waterproof cavities.
[0004] The aforementioned traditional underwater lights, due to the accumulation of components and unpredictable factors on the seabed such as impacts, pose a risk of damage and leakage to the power supply, or the light rolling close to the inner wall, causing a short circuit. The overall design of the lights is often large and complex, which hinders the dissipation of heat inside the lights and increases the weight of the lights. When water leakage occurs, all components inside the lights are at risk of short circuits, which can easily render the lights unusable and difficult to repair and reuse. This greatly hinders deep-sea exploration and other activities, and is not conducive to large-scale, long-term marine operations. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressure-resistant LED underwater light with the advantages of power protection, simplified pressure resistance, and leakage prevention.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pressure-resistant LED underwater light, comprising:
[0007] The cylindrical body is used to install the foundation, and its inner wall is equipped with partitions.
[0008] A light source is installed on the surface of the partition layer;
[0009] The front cover is mounted above the light source, screwed to the cylinder, and forms an optical cavity with the partition.
[0010] The tail cap is fitted onto the side of the cylinder away from the front cap and forms a power supply cavity with the partition.
[0011] An isolation post is inserted into the top of the tail cap.
[0012] The driving battery is plugged into the isolation post and located inside the power supply cavity.
[0013] In one embodiment, the front cover includes a front cover and a lens, the front cover being screwed to the outer wall of the cylinder, and the lens being installed inside the front cover.
[0014] In one embodiment, the cylindrical body forms an annular support wall on the inner periphery of the optical cavity, and a first annular groove is provided on the top of the annular support wall. A first waterproof ring is fitted on the first annular groove, and the first waterproof ring abuts against the bottom of the lens.
[0015] In one embodiment, a second annular groove is provided in one end of the cylinder near the tail cap, and a retaining ring is engaged in the second annular groove to restrict the movement of the tail cap.
[0016] In one embodiment, the retaining ring is made of a flexible metal material, and the lens is made of tempered glass.
[0017] In one embodiment, the tail cap includes a tail cap and a watertight connector. The tail cap abuts against the bottom of the cylinder and has a through hole. The watertight connector is inserted into the through hole.
[0018] In one embodiment, the outer wall of the tail cap is provided with an annular groove, and a second waterproof ring is fitted on the annular groove, the second waterproof ring abutting against the inner wall of the cylinder.
[0019] In one embodiment, a potting compound layer is provided inside the power supply cavity, and the potting compound layer is disposed between the cylinder and the driving battery.
[0020] In one embodiment, the partition has a through hole, through which the light source is electrically connected to the driving battery.
[0021] In one embodiment, a blister cup is mounted on top of the light source, and the blister cup is located inside the optical cavity.
[0022] The above-mentioned pressure-resistant LED underwater light has the following beneficial effects:
[0023] Firstly, the driver battery of the entire lamp is fixed by the isolation column, which makes the driver battery firm and stable in the installation position, and has the effect of buffering and shock absorption. This prevents the driver battery from being damaged and leaking after the entire lamp is affected by factors such as impact, or from coming into contact with the inner wall of the lamp and causing a short circuit.
[0024] Secondly, the lamp has a simplified structure, which is beneficial for heat dissipation and reduces its size and weight. The treatment of the joints makes the lamp have an external sealing effect, which can play a role in sealing and preventing leakage, and resisting pressure.
[0025] Third, the cavity is a closed space, and the cavities are independent of each other in terms of waterproofing. The components placed in the cavity can be isolated and protected from the conditions of other cavities. Attached Figure Description

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, unless otherwise explicitly specified.
[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0037] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0038] A pressure-resistant LED underwater light, such as Figure 2 and Figure 5 As shown, it includes a cylindrical body 1, a light source 2, a front cover 3, a tail cover 4, an isolation column 5, and a driving battery 6;
[0039] The cylindrical body 1 is used for mounting the foundation, and its inner wall is provided with a partition 111; the light source 2 is installed on the surface of the partition 111; the front cover 3 is installed above the light source 2, screwed to the cylindrical body 1, and forms an optical cavity with the partition 111; the tail cover 4 is snapped onto the side of the cylindrical body 1 away from the front cover 3, and forms a power cavity with the partition 111; the isolation column 5 is inserted into the top of the tail cover 4; the drive battery 6 is inserted into the isolation column 5 and is located in the power cavity.
[0040] The above design, in one example, offers several advantages. In an underwater environment, the entire lamp comes into contact with water from all directions. The cylindrical body 1 and front cover 3 are designed as cylindrical structures, better able to withstand water pressure from all directions. Externally, the connection methods between the cylindrical body 1 and front cover 3, and between the cylindrical body 1 and tail cover 4, ensure a tight, leak-proof seal, forming a unified whole. This simplifies the overall size and component composition, facilitating heat dissipation. Internally, when the lamp is affected by external forces and leaks, the optical cavity and power supply cavity can be independently isolated, protecting the components within each cavity and preventing short circuits. For the drive battery 6 within the power supply cavity, the isolation pillar 5 securely supports and protects it, preventing it from rolling out of its original position and leaking, potentially causing a short circuit due to contact with the inner wall.
[0041] like Figure 1-2 As shown, the front cover 3 includes a front cover 31 and a lens 32. The front cover 31 is screwed to the outer wall of the cylinder 1, and the lens 32 is installed inside the front cover 31. In one example, the advantage of this design is that the connection between the front cover 31 and the cylinder 1 is screwed, ensuring a tight connection between the front cover 3 and the cylinder 1, thus waterproofing the optical cavity. The lens 32 can withstand the external force on the top of the front cover 3, protecting and sealing the optical cavity. Simultaneously, it allows light emitted from the light source 2 inside the optical cavity to pass through the lens 32, achieving an illumination effect.
[0042] like Figure 3 and Figure 5 As shown, the cylindrical body 1 forms an annular support wall 12 on the inner circumference of the optical cavity. A first annular groove 121 is formed at the top of the annular support wall 12, and a first waterproof ring 7 is fitted onto the first annular groove 121. The first waterproof ring 7 abuts against the bottom of the lens 32. With this design, in one example, the advantage is that the abutment between the first waterproof ring 7 and the bottom of the lens 32 makes it difficult for external water to enter the optical cavity from between the first waterproof ring 7 and the lens 32, thus further enhancing the sealing performance of the optical cavity.
[0043] like Figure 3 and Figure 6 As shown, a second annular groove 13 is provided in the end of the cylinder 1 near the tail cap 4, and a retaining ring 9 is engaged in the second annular groove 13 to restrict the movement of the tail cap 4. With the above design, in one example, the advantage is that when the entire lamp is affected by external force, the tail cap 4 is restricted by the retaining ring 9 and cannot completely detach from the bottom of the cylinder 1, ensuring a tight connection between the tail cap 4 and the cylinder 1, so that the power supply cavity can be stable and not easily damaged.
[0044] The retaining ring 9 is made of elastic metal, and the lens 32 is made of tempered glass. In one example, the advantages of this design are that the elastic metal material of the retaining ring 9 provides tension, making it easier for the retaining ring 9 to engage with the second annular groove 13; and the tempered glass material of the lens 32 better withstands the pressure from the top of the front cover 3, ensuring the airtightness of the optical cavity.
[0045] like Figure 3-4 As shown, the tail cap 4 includes a tail cap 41 and a watertight connector 42. The tail cap 41 abuts against the bottom of the cylinder 1, and the tail cap 41 has a through hole 411. The watertight connector 42 is inserted into the through hole 411. In one example, the advantage of this design is that the connection between the tail cap 41 and the cylinder 1 is abutted, ensuring a tight connection between the tail cap 4 and the cylinder 1, thus providing a waterproof function for the power supply cavity. Furthermore, the watertight connector 42, inserted into the through hole 411, ensures a tight connection between the watertight connector 42 and the tail cap 41, thus providing a protective seal for the optical cavity.
[0046] like Figure 3-4 As shown, an annular groove 412 is formed on the outer wall of the tail cap 41, and a second waterproof ring 8 is fitted onto the annular groove 412. The second waterproof ring 8 abuts against the inner wall of the cylinder 1. With the above design, in one example, the advantage is that, since the second waterproof ring 8 abuts against the inner wall of the cylinder 1, it is difficult for external water to enter the power supply cavity from between the second waterproof ring 8 and the inner wall of the cylinder 1, which can further enhance the sealing of the power supply cavity.
[0047] A potting compound layer is provided inside the power supply cavity, and the potting compound layer is disposed between the cylinder 1 and the driving battery 6. With the above design, in one example, the advantage is that by placing the potting compound layer between the cylinder and the driving battery 6, the heat dissipation performance of the driving battery 6 can be effectively improved, thereby enhancing the overall heat dissipation effect of the lamp.
[0048] like Figure 2 and Figure 5 As shown, the partition 11 has a through hole 111, through which the light source 2 is electrically connected to the driving battery 6. In one example, the advantage of this design is that the light source 2 and the driving battery 6 are housed within their respective cavities, ensuring isolation and protection while still allowing for electrical connection via the through hole 111, which is beneficial for the overall operation of the lamp.
[0049] like Figure 2 As shown, a blister cup 10 is mounted on top of the light source, and the blister cup 10 is located inside the optical cavity. With the above design, in one example, the advantage is that the blister cup 10 is not only aesthetically pleasing, but also softens the light emitted by the light source 2 after passing through the blister cup 10, and reduces glare. In addition, the blister cup 10 also has the function of expanding the illumination range of the light source 2 and concealing the light source 2.
[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
