Description

Technical Field

[0001] This utility model relates to the technical field of lighting equipment, and more specifically, it relates to a deep-sea pressure-resistant focused LED lamp. Background Technology

[0002] With the advancement of science and technology, the exploration and resource development of the deep sea have received increasing attention. The deep sea is a high-pressure liquid environment, and natural light becomes weaker and weaker with increasing depth. Therefore, underwater lighting sources have become an indispensable tool for deep-sea exploration.

[0003] Traditional underwater lights are large and complex, often making them unsuitable for long-term stable operation and hindering deep-sea exploration activities. LED lights, as a new type of light source, have been widely used in deep-sea lighting due to their long lifespan, small size, and high luminous efficiency. However, conventional LED underwater lights have a large beam angle and short underwater illumination distance, making the development of a pressure-resistant, focused LED light fixture suitable for deep-sea applications imperative. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a deep-sea pressure-resistant focused LED lamp with the advantages of high pressure resistance and strong light concentration.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a deep-sea pressure-resistant focused LED light fixture, comprising:

[0006] Lamp holder;

[0007] The front cover is screwed to the top of the lamp head and forms an optical cavity with the lamp head;

[0008] The light source is mounted on the lamp head and located inside the optical cavity;

[0009] A reflector is mounted on the light source and located inside the optical cavity;

[0010] The cylindrical body is screwed to the bottom of the lamp holder and together with the lamp holder forms a power supply cavity;

[0011] A power supply assembly is connected to the bottom of the cylinder and located inside the power supply cavity;

[0012] An adhesive layer is disposed within the power supply cavity and located between the cylinder and the power supply assembly.

[0013] In one embodiment, the reflector includes a lamp cup and a convex lens, the lamp cup being located at the top of the light source and the convex lens being located at the middle of the lamp cup.

[0014] In one embodiment, a limiting ring is also provided inside the power supply cavity. The limiting ring is engaged with the power supply assembly and abuts against the inner side of the cylinder.

[0015] In one embodiment, a Mylar sheet is provided on the inner side of the cylinder, and the Mylar sheet is located between the limiting ring and the cylinder.

[0016] In one embodiment, the upper surface of the lamp head is provided with a light source bracket, which is connected to the bottom of the reflector and located between the light source and the reflector.

[0017] In one embodiment, the front cover further includes a lens disposed between the front cover and the lamp head.

[0018] In one embodiment, waterproof rings are provided between the lamp head and the cylinder body, and between the lamp head and the bottom of the lens.

[0019] In one embodiment, a watertight component is also included, with a through opening at the bottom of the cylinder, and the watertight component is inserted into the opening.

[0020] In one embodiment, the lamp head has an opening through which the light source is electrically connected to the battery.

[0021] The above-mentioned deep-sea pressure-resistant focused LED light fixture has the following beneficial effects:

[0036] A deep-sea pressure-resistant focused LED light fixture, such as Figures 1 to 3 As shown, it includes a lamp head 1, a front cover 2, a light source 212, a reflector 211, a cylinder 3, a power supply assembly 311, and a sealing layer 312;

[0037] The front cover 2 is screwed to the top of the lamp head 1 and together with the lamp head 1 forms an optical cavity 21; the light source 212 is mounted on the lamp head 1 and located inside the optical cavity 21; the reflector 211 is mounted on the light source 212 and located inside the optical cavity 21; the cylindrical body 3 is screwed to the bottom of the lamp head 1 and together with the lamp head 1 forms a power supply cavity 31; the power supply assembly 311 is located inside the power supply cavity 31; and the sealing layer 312 is located inside the power supply cavity 31 and between the cylindrical body 3 and the power supply assembly 311.

[0038] The top of the lamp head 1 is threadedly connected to the front cover 2, forming an optical cavity 21 for housing optical components such as the light source 212 and reflector 211. The bottom of the lamp head 1 is threadedly connected to the top of the cylinder 3, forming a power supply cavity 31 for housing a power supply component 311, such as a drive power supply. The front cover 2, lamp head 1, and cylinder 3 together constitute the outer shell of the deep-sea pressure-resistant focused LED lamp. The reflector 211 is located inside the optical cavity 21, reducing the beam angle of the light emitted by the light source 212 and acting as a focuser. The power supply component 311 includes a power board and a drive power supply, etc. The drive power supply is mounted on the power board. The top and bottom of the cylinder 3 have grooves that match the power board, fixing the power board inside the power supply cavity 31. A potting compound with excellent thermal conductivity and insulation is selected and injected into the power supply cavity 31 to fill the remaining space of the power supply cavity 31, forming a sealing layer 312. The sealing layer 312 not only improves the heat dissipation performance of the power supply component 311, but also turns the power supply cavity 31 into a sealed body, thereby improving the pressure resistance performance of the power supply cavity 31. In this embodiment, the vertical cross-section of the lamp holder 1 is H-shaped, and the light source 212 adopts a high-density COB LED light source 212.

[0039] By setting a sealing layer 312 inside the power supply cavity 31, the power supply cavity 31 becomes a sealed body, improving its ability to withstand underwater high pressure. By setting a reflector cup 211 inside the optical cavity 21, the beam angle of the light source 212 is reduced, the central light intensity is increased, and small-angle focusing is achieved.

[0040] Furthermore, such as Figure 2 and Figure 3 As shown, the reflector 211 includes a lamp cup 2111 and a convex lens 2112. The lamp cup 2111 is located at the top of the light source 212, and the convex lens 2112 is located in the middle of the lamp cup 2111.

[0041] The reflector cup 2111 has a shape with a small opening at the bottom and a large opening at the top. The bottom of the reflector cup 2111 is in close contact with the top of the light source 212. The shape of the bottom being smaller and the top being larger achieves primary light focusing. A convex lens 2112 is provided in the middle of the reflector cup 2111, which achieves secondary light focusing. The two light distributions achieve small-angle focusing. The material of the reflector cup 2111 is not limited here, as long as it can work normally in the deep sea environment, such as a metal or alloy material with good pressure resistance, heat dissipation and corrosion resistance. In this embodiment, the reflector cup 2111 is integrally formed.

[0042] Specifically, such as Figure 2 and Figure 3 As shown, a limiting ring 313 is also provided inside the power supply cavity 31. The limiting ring 313 is engaged with the power supply assembly 311 and abuts against the inner side of the cylinder 3.

[0043] The retaining ring 313 is tightly fastened to the power board to maintain the electrical distance between the power assembly 311 and the inner side of the cylinder 3, preventing short circuits and improving electrical reliability. The number and material of the retaining rings 313 are not limited here; they only need to have excellent hardness and achieve the above-mentioned functions. In this embodiment, the retaining ring 313 is a thin plastic sheet.

[0044] Furthermore, such as Figure 2 As shown, a Mylar plate 32 is provided on the inner side of the cylinder 3, and the Mylar plate 32 is located between the limiting ring 313 and the cylinder 3.

[0045] The Mylar plate 32 is tightly attached to the inner side of the cylinder 3, and its size and shape correspond to those of the cylinder 3. The Mylar plate 32 is used to enhance the sealing, waterproofing, corrosion resistance, and insulation of the power supply cavity 31.

[0046] Specifically, such as Figure 2 and Figure 3 As shown, the upper surface of the lamp head 1 is provided with a light source bracket 213, which is connected to the bottom of the reflector cup 211 and is located between the light source 212 and the reflector cup 211.

[0047] The light source bracket 213 fixes the reflector cup 211 and the light source 212 to the lamp head 1 from top to bottom with mounting screws. The close contact between the light source 212 and the lamp head 1 can improve heat dissipation performance, and the close contact between the reflector cup 211 and the light source 212 can improve light utilization and focusing effect.

[0048] Specifically, such as Figure 2 and Figure 3 As shown, the front cover 2 also includes a lens 22, which is located between the front cover 2 and the lamp head 1.

[0049] The lens 22 is located directly above the reflector 211. As part of the front cover 2, it, together with the cylinder 3 and the lamp head 1, achieves overall sealing and waterproofing. The material of the lens 22 is not limited here, as long as it has good light transmittance, pressure resistance, and corrosion resistance, such as tempered glass or polyvinyl chloride.

[0050] Specifically, such as Figure 3 As shown, waterproof rings 11 are provided between the lamp head 1 and the cylinder 3, and between the lamp head 1 and the bottom of the lens 22.

[0051] A waterproof ring 11 is provided between the top of the lamp head 1 and the lens 22 to improve the sealing and waterproofing of the optical cavity 21. A waterproof ring 11 is provided between the bottom of the lamp head 1 and the cylinder 3 to improve the sealing and waterproofing of the power supply cavity 31. The number and position of the waterproof rings 11 are not limited, and they can be added at other locations. In this embodiment, the waterproof rings 11 are O-shaped, with two waterproof rings 11 provided between the top of the lamp head 1 and the lens 22, and two waterproof rings 11 also provided between the bottom of the lamp head 1 and the cylinder 3.

[0052] Specifically, such as Figures 1 to 3 As shown, it also includes a watertight component 4. The bottom of the cylinder 3 is provided with a through opening 12, and the watertight component 4 is inserted into the opening 12.

[0053] The watertight component 4 has good sealing and durability, effectively improving the waterproofness of the cylinder 3.

[0054] Specifically, such as Figure 3 As shown, the lamp holder 1 has an opening, and the light source 212 is electrically connected to the power supply component 311 through the opening.

[0055] The lamp holder 1 has multiple openings in the middle, through which the light source 212 and the power supply component 311 are connected by wires to achieve electrical connection.

[0056] 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.
