Description

Technical Field

[0001] The present invention relates to the technical field of lighting, and in particular to a high-reliability marine lighting lamp. Background Art

[0002] Overhead lighting is commonly used in various indoor and outdoor locations on ships. Due to the unique marine environment, these locations are often exposed to humidity and salt spray. Therefore, lighting installed in engine rooms, cargo holds, work areas, exterior passageways, and exposed or semi-exposed areas is prone to corrosion. Summary of the Invention

[0003] The object of the present invention is to provide a highly reliable marine lighting lamp to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is as follows: a high-reliability marine lighting lamp is used in marine ships, the lighting lamp comprises: a lamp housing, which is equipped with a lampshade and a lamp body assembly, a sealing ring is installed between the lamp housing and the lampshade, a first enclosed space is formed between the lamp housing and the lampshade, and the lamp body assembly is located in the first enclosed space; a breathing tube is installed in the lamp housing, a piston plate is vertically slid in the breathing tube, and a second enclosed space is formed with the piston plate and the breathing tube, a plurality of breathing tubes are distributed around the bottom of the breathing tube, one end of the breathing tube is connected to the second enclosed space, and the other end extends downward along the outer wall of the lamp housing, the breathing tube A plurality of breathing holes are provided. When the marine vessel shakes, the piston plate slides up and down in the breathing tube. A first salt mist adsorption layer is used to adsorb salt mist particles in the air. The first salt mist adsorption layer is installed in the second sealed space. When the piston plate slides downward in the breathing tube, the air in the second enclosed space is filtered by the first salt mist adsorption layer and then flows out to the outer wall of the lamp housing through the plurality of breathing tubes. When the piston plate slides upward in the breathing tube, the air on the outer wall of the lamp housing is sucked into the breathing tube through the plurality of breathing tubes and enters the second enclosed space after being filtered by the first salt mist adsorption layer.

[0005] This technical solution has at least the following beneficial effects: when the ship at sea is shaking, the piston plate slides up and down frequently in the breathing tube, and the volume in the second confined space constantly changes, so that continuous positive and negative airflows are formed in the breathing tube. When the air around the lamp housing and lampshade is sucked into the first confined space, the content of salt mist particles can be reduced under the adsorption action of the first salt mist adsorption layer, so that the content of salt mist particles in the gas exhaled from the breathing tube is relatively low. That is, when the piston plate continuously slides up and down, the content of salt mist particles around the lamp housing and lampshade can be reduced by drawing in air with a higher salt mist particle content and exhaling air with a lower salt mist particle content, thereby reducing the salt mist particle content around the lamp housing and lampshade, thereby reducing the corrosion effect of salt mist particles on the lamp housing and lampshade, even if the lamp housing and lampshade are not so prone to corrosion.

[0006] As a further improvement to the above technical solution, a support shaft is rotatably mounted on the bottom of the breathing tube, a connecting rod is rotatably mounted on the top of the support shaft, and its rotation axis is perpendicular to the axis of the support shaft. An annular groove is formed at the bottom of the piston plate, and a gravity block is rotatably mounted on the end of the connecting rod away from the support shaft. The gravity block is slidably disposed in the annular groove. The lamp housing is equipped with a centrifugal fan within the first enclosed space, and the support shaft is used to drive the centrifugal fan to rotate. When the ship at sea shakes, the gravity block slides within the annular groove, driving the support shaft to rotate, causing the centrifugal fan to rotate, thereby causing air in the first enclosed space to flow, thereby dissipating heat from the lamp body assembly.

[0007] As a further improvement to the above technical solution, a first drive plate connected to the bottom of the support shaft is rotatably mounted at the bottom of the respirator, a second drive plate is mounted at the top of the centrifugal fan, and the second drive member is rotatably mounted on the inner sidewall of the lamp housing. The first drive plate is ringed with a plurality of first magnetic blocks, and the second drive plate is ringed with a plurality of second magnetic blocks. When the first drive plate rotates, the interaction between the first and second magnetic blocks drives the second drive plate to rotate. The interaction between the first and second magnetic blocks enables the first and second drive plates to be connected in a transmission manner, which can reduce the need for opening holes in the lamp housing and ensure the sealing of the first enclosed space.

[0008] As a further improvement of the above technical solution, the centrifugal fan includes a conical shell installed on the inner wall of the lamp housing and a second drive plate rotatably installed on the inner wall of the lamp housing, the opening area of ​​the conical shell away from the end of the second drive plate is smaller than the opening area close to the end of the second drive plate, the second drive plate is ringed with a plurality of blades located between the conical shell and the second drive plate, and the outer periphery of the conical shell close to the end of the second drive plate is ringed with a plurality of air outlets.

[0009] As a further improvement to the above technical solution, the lamp body assembly includes a mounting plate mounted on the lamp housing and a lamp tube mounted on the mounting plate, with the end of the conical shell distal from the second driving plate extending through the mounting plate. This improves the flow between the upper and lower spaces of the mounting plate, preventing heat from accumulating in the lamp tube.

[0010] As a further improvement to the above technical solution, the conical housing has an air inlet at one end distal from the second drive plate. A second salt mist adsorption layer is installed in the air inlet to adsorb salt mist particles in the air. When the centrifugal fan rotates, an internal circulation through the second salt mist adsorption layer is formed within the first enclosed space, thereby maintaining a low salt mist particle concentration in the first enclosed space.

[0011] As a further improvement of the above technical solution, the breathing tube is connected to a connecting tube at one end close to the breathing cylinder, the other end of the connecting tube is connected to the second confined space and the connection position is above the first salt mist adsorption layer, and the connecting tube is installed with a first one-way door, which allows air in the second confined space to enter the connecting tube and blocks the air in the connecting tube from entering the second confined space.

[0012] As a further improvement to the above technical solution, a fixing groove is defined on the outer periphery of the lampshade, and the sealing ring includes a sealing portion and a mounting portion that fits into the fixing groove. The sealing portion is clamped between the lampshade and the lamp housing, and the mounting portion defines an inner hole whose length is the same as that of the sealing ring. This facilitates installation of the sealing ring and ensures its reliability and stability.

[0013] As a further improvement of the above technical solution, a limiting groove is opened at the bottom of the edge of the lamp shell, the sealing part is in contact with the bottom wall of the limiting groove, the width of the mounting part is greater than the width of the edge of the lampshade, and the width of the limiting groove is greater than the width of the mounting part.

[0014] As a further improvement of the above technical solution, one of the lamp housing and the lamp shade is provided with a buckle, and the other is provided with a slot for the buckle to be engaged, thereby simplifying the assembly of the lamp housing and the lamp shade and facilitating maintenance.

[0032] Example 1:

[0033] Reference Figure 1-10 A high-reliability marine lighting lamp includes a lamp housing 100, a lampshade 200, a lamp body assembly 300, a sealing ring 310 and a breathing mechanism.

[0034] The opening of the lamp housing 100 is downwardly facing, while the opening of the lamp shade 200 is upwardly facing. The bottom edge of the lamp housing 100 and the top edge of the lamp shade 200 overlap each other, forming a first enclosed space between the lamp housing 100 and the lamp shade 200. The sealing ring 310 is adapted to be installed at the position where the lamp housing 100 and the lamp shade 200 overlap each other, thereby ensuring the sealing of the first enclosed space.

[0035] The lamp body assembly 300 is located within the first enclosed space and includes a mounting plate 301 and a lamp tube 302. The mounting plate 301 is secured to the interior of the lamp housing 100 via angle brackets and is horizontally positioned in the center of the first enclosed space. It is stamped from steel and coated with a white powder coating, significantly enhancing the lamp's reflective properties and achieving a high lumen output. The lamp tube 302 is mounted at the bottom of the mounting plate 301 via a lamp holder 303 at the end. The lamp housing 100 is equipped with a connector 110. Cables supplying power and control signals to the lamp tube 302 are connected to the lamp holder 303 within the lamp housing 100 through the connector 110. The lamp holder 303 then connects to a plug at the end of the lamp tube 302, completing the cable connection. The connector 110 can be a waterproof plastic connector, significantly reducing product cost. Light emitted by the lamp tube 302 is transmitted outward through the lampshade 200, providing illumination.

[0036] There are two breathing mechanisms, which are respectively distributed on both sides of the top of the lamp housing 100. The breathing mechanism includes a breathing cylinder 400, a piston plate 410, a breathing tube 420 and a first salt mist adsorption layer 500.

[0037] The outer periphery of the bottom of the breathing cylinder 400 is provided with a flange edge, which is fixed to the top of the lamp housing 100 by bolts, thereby installing the breathing cylinder 400 on the top of the lamp housing 100. The inner dimensions of the breathing cylinder 400 are the same as the outer dimensions of the piston plate 410, so that the piston plate 410 can just slide vertically inside the breathing cylinder 400. Limiting inner rings are provided on the inner side of the top and the inner side of the middle and lower parts of the breathing cylinder 400. The two limiting inner rings respectively limit the upper sliding limit position and the lower sliding limit position of the piston plate 410, so that the piston plate 410 will not separate from the breathing cylinder 400. A second closed space is formed between the bottom of the piston plate 410 and the inner bottom of the breathing cylinder 400.

[0038] Multiple breathing tubes 420 are provided, each arranged around the periphery of the breathing tube 400. One end of each breathing tube 420 communicates with the second enclosed space within the breathing tube 400, while the other end extends downward along the outer wall of the lamp housing 100. The end of the breathing tube 420 away from the breathing tube 400 may extend to the connection between the lamp housing 100 and the lampshade 200, or to the outer wall of the lampshade 200. Multiple breathing holes 421 are formed on the outer side of the breathing tube 420 away from the lamp housing 100, with the opening area of ​​the breathing holes 421 increasing as the distance from the breathing tube 400 increases.

[0039] The first salt mist adsorption layer 500 is composed of one or more of an absorbent chemical fiber layer, glass fiber filter paper, PTFE filter material, and activated carbon, enabling it to adsorb salt mist particles. The first salt mist adsorption layer 500 is installed inside the breathing tube 400 and is located below the lower limiting inner ring, preventing the piston plate 410 from interfering with the first salt mist adsorption layer 500. A certain amount of space is reserved between the bottom of the first salt mist adsorption layer 500 and the bottom wall of the breathing tube 400 to allow air flow. The end of the breathing tube 420 that connects to the second enclosed space is located below the first salt mist adsorption layer 500.

[0040] A steel plate frame is installed on the top of the lamp housing 100 by bolts, and both ends of the steel plate frame extend out of both sides of the lamp housing 100, so that both ends of the steel plate frame can be installed at the positions where they need to be fixed by bolts, thereby facilitating the fixed installation of the lamp housing 100, that is, the fixed installation of the lighting lamp.

[0041] The lighting lamp of the present application is installed on a ship at sea. When the ship at sea is in a shaking state, the position of the breathing tube 400 fluctuates up and down, and the piston plate 410 slides up and down relative to the breathing tube 400 due to inertia.

[0042] When the piston plate 410 slides upward relative to the breathing tube 400, the volume of the second enclosed space increases, causing the air pressure in the second enclosed space to decrease. Under the action of this pressure, the breathing holes 421 on the multiple breathing tubes 420 draw air from the outer periphery of the lamp housing 100 into the breathing tube 400. After passing through the first salt mist adsorption layer 500, the air enters the position between the piston plate 410 and the first salt mist adsorption layer 500. It can be understood that after being filtered by the first salt mist adsorption layer 500, the air between the piston plate 410 and the first salt mist adsorption layer 500 has a lower salt mist particle content.

[0043] When the piston plate 410 slides downward relative to the breathing tube 400, the volume of the second enclosed space decreases, increasing the air pressure within the second enclosed space. Under the action of this pressure, the air in the second enclosed space passes through the first salt mist adsorption layer 500 and flows out through the breathing holes 421 of the multiple breathing tubes 420. Air with a low salt mist content is discharged through the multiple breathing holes 421 of the multiple breathing tubes 420, thereby allowing air with a low salt mist content to pass through the periphery of the lamp housing 100. This reduces the salt mist content around the lamp housing 100 and lampshade 200, further minimizing the corrosion effects of salt mist on the lamp housing 100 and lampshade 200. This reduces the corrosion susceptibility of the lamp housing 100 and lampshade 200, thereby increasing the service life of the lamp.

[0044] It is understood that when the salt mist particle content reaches a certain concentration, the corrosion effect on the structure is the strongest. Therefore, reducing the salt mist particle content outside the lighting lamp can effectively reduce the corrosion effect and better protect the lighting lamp. Furthermore, an outer cover that does not react with salt mist particles can be placed on the outer cover of the lamp housing 100. The outer cover is located outside the lighting lamp, creating a space with poor air circulation between the lighting lamp and the outer cover, thereby increasing the amount of air outside the lighting lamp with a lower salt mist particle content.

[0045] When the air passes through the first salt mist adsorption layer 500, the salt mist particles in the air are intercepted in the first salt mist adsorption layer 500. After entering the first salt mist adsorption layer 500, the salt mist particles adhere to or get stuck in the first salt mist adsorption layer 500 and cannot easily escape from the first salt mist adsorption layer 500, thereby ensuring that the air blown out of the breathing tube 420 has a low salt mist particle content.

[0046] In another embodiment, the first salt mist adsorption layer 500 can be positioned at the top of the piston plate 410, and the breathing tube 420 can be connected to the top of the breathing tube 400. The top of the breathing tube 400 is sealed, and the bottom of the breathing tube 400 is open to the outside world, so that the piston plate 410 can slide up and down within the breathing tube 400. The second enclosed space is the space between the top of the piston plate 410 and the inner top wall of the breathing tube 400. When the piston plate 410 slides upward relative to the breathing tube 400, the volume of the second enclosed space decreases, and air with a low salt mist particle content is discharged. When the piston plate 410 slides downward relative to the breathing tube 400, the volume of the second enclosed space increases, and air with a high salt mist particle content is drawn in for filtration.

[0047] To reduce the overall height of the product, both sides of the top of the lamp housing 100 are recessed to accommodate the breathing tube 400. The top surface of the breathing tube 400 is slightly lower than the top surface of the central portion of the lamp housing 100, which is not recessed, to ensure the proper sliding of the piston plate 410 within the breathing tube 400. The two breathing tubes 420 near the center of the lamp housing 100 do not extend downward along the outer walls of the lamp housing 100, but instead extend toward the center of the lamp housing 100.

[0048] Furthermore, a support shaft 600 is rotatably mounted in the middle of the bottom wall of the respirator 400, a connecting rod 610 is rotatably mounted on the top of the support shaft 600, and a weight block 630 is rotatably mounted on the end of the connecting rod 610 away from the support shaft 600. The axis of the support shaft 600 is vertically arranged, the connecting rod 610 and the rotation centerline of the support shaft 600 are horizontally arranged, and the rotation centerline between the connecting rod 610 and the weight block 630 is parallel to the rotation centerline of the connecting rod 610 and the support shaft 600. An annular groove 620 is provided on the bottom edge of the piston plate 410, the annular center of the annular groove 620 corresponding to the center of the piston plate 410. The weight block 630 is arc-shaped and slidably mounted in the annular groove 620. The weight block 630 can slide a certain distance in the direction of the rotation radius within the annular groove 620 to ensure that the rotation of the weight block 630 does not interfere with the up and down sliding of the piston plate 410.

[0049] When the ship at sea is in a shaking state, the horizontal position of the breathing cylinder 400 changes irregularly, and the gravity block 630 slides in the annular groove 620 under the action of inertia, thereby driving the support shaft 600 to rotate.

[0050] In other embodiments, two or more connecting rods 610 may be arranged around the support shaft 600 so that the multiple gravity blocks 630 connected to the multiple connecting rods 610 slide in the annular groove 620 to ensure the sliding stability of the piston plate 410.

[0051] A centrifugal fan 800 is installed inside the lamp housing 100. The centrifugal fan 800 is located in the first enclosed space and is located at the top of the mounting plate 301. The support shaft 600 is in transmission connection with the centrifugal fan 800. When the support shaft 600 rotates, it drives the centrifugal fan 800 to rotate.

[0052] Specifically, the centrifugal fan 800 includes a conical shell 810 , a second driving plate 820 and a plurality of blades 830 .

[0053] The cone shell 810 is in the shape of a tapered cylinder, and the top opening area of ​​the cone shell 810 is larger than the bottom opening area. The cone shell 810 is fixedly mounted on the inner top wall of the lamp housing 100. The second drive plate 820 is rotatably mounted on the inner top wall of the lamp housing 100. The second drive plate 820 is at the top position inside the cone shell 810, and a plurality of air outlets 811 are arranged around the outer periphery of the top of the cone shell 810. The bottom of the cone shell 810 is an air inlet 812. A plurality of blades 830 are evenly arranged around the bottom wall of the second drive plate 820, so that when the second drive plate 820 rotates, the plurality of blades 830 can be driven to rotate together, but the cone shell 810 does not rotate, so that a smaller power can also drive the blades 830 in the centrifugal fan 800 to rotate.

[0054] A first drive plate 700 is rotatably mounted on the outer bottom of the breathing tube 400. The bottom of the support shaft 600 extends through the bottom of the breathing tube 400 and is fixedly connected to the center of the first drive plate 700. Rotating the support shaft 600 drives the first drive plate 700. The center of the first drive plate 700 is aligned vertically with the center of the second drive plate 820.

[0055] A plurality of first magnetic blocks 710 are evenly arranged around the edge of the first driving plate 700, and a plurality of second magnetic blocks 821 are evenly arranged around the edge of the second driving plate 820. The number of the first magnetic blocks 710 is the same as the number of the second magnetic blocks 821, and the radius of the plurality of first magnetic blocks 710 is the same as the radius of the plurality of second magnetic blocks 821.

[0056] When the first magnetic block 710 and the second magnetic block 821 have the same magnetic poles and repel each other, the first magnetic block 710 and the second magnetic block 821 intersect and stagger due to mutual repulsion. Furthermore, when the support shaft 600 drives the first drive plate 700 to rotate, the first magnetic block 710 pushes the second magnetic block 821 below the forward direction to move, thereby driving the second drive plate 820 to rotate, achieving a transmission connection between the support shaft 600 and the centrifugal fan 800 and driving the centrifugal fan 800 to rotate. When the blades 830 in the centrifugal fan 800 rotate, centrifugal wind is generated inside the conical shell 810, causing air to enter through the air inlet 812 of the conical shell 810 and be ejected from the air outlet 811 under the action of the blades 830, thereby achieving gas flow within the first enclosed space.

[0057] In another embodiment, when the first magnetic block 710 and the second magnetic block 821 have opposite magnetic poles and attract each other, the first magnetic block 710 and the second magnetic block 821 are in a one-to-one correspondence due to mutual attraction. Furthermore, when the support shaft 600 drives the first drive plate 700 to rotate, the first magnetic block 710 pulls the corresponding second magnetic block 821 below to move, thereby pulling the second drive plate 820 to rotate, achieving a transmission connection between the support shaft 600 and the centrifugal fan 800, driving the centrifugal fan 800 to rotate.

[0058] In other embodiments, the support shaft 600 may be further extended downward to penetrate the interior of the lamp housing 100, and the bottom of the support shaft 600 may be connected to the middle of the second drive plate 820. When the support shaft 600 rotates, it can directly drive the second drive plate 820 to rotate, thereby driving the centrifugal fan 800 to rotate.

[0059] Furthermore, a second salt mist adsorption layer 840 is installed at the air inlet 812 of the conical shell 810. The second salt mist adsorption layer 840 is composed of one or more of an absorbent chemical fiber layer, glass-limited filter paper, PTFE filter material, and activated carbon, enabling the second salt mist adsorption layer 840 to adsorb salt mist particles. When the centrifugal fan 800 is operating, air in the first enclosed space enters through the air inlet 812 and is filtered and adsorbed by the second salt mist adsorption layer 840, whereupon air with a low salt mist particle content is discharged, thereby maintaining a low salt mist particle content within the first enclosed space. In particular, when the lampshade 200 is closed after being opened to repair the lamp tube 302, the first enclosed space may contain a large amount of salt mist particles. Therefore, after a certain period of time, the salt mist particles in the first enclosed space are filtered and adsorbed by the second salt mist adsorption layer 840, thereby maintaining a low salt mist particle content in the first enclosed space and slowing the corrosion of the structure within the first enclosed space.

[0060] Furthermore, the bottom end of the conical shell 810, i.e., one end of the air inlet 812, is provided in the mounting plate 301. It is understandable that the mounting plate 301 is provided with a through hole for the bottom end of the conical shell 810 to pass through. The centrifugal fan 800 draws air from the space below the mounting plate 301 and discharges it from the space above the mounting plate 301, thereby promoting air circulation between the upper and lower spaces of the mounting plate 301, reducing the excessive accumulation of heat generated by the lamp tube 302, and balancing the temperature in the first enclosed space. The corrosive effect of salt spray particles is also affected by temperature. Therefore, by balancing the temperature in the first enclosed space and reducing areas with excessively high temperatures, it is possible to reduce the serious corrosion of structures with locally high temperatures.

[0061] Furthermore, the outer edge of the lampshade 200 protrudes outward to form a wider border, and a fixing groove 210 is provided on the top surface of the border. The fixing groove 210 is arranged around the outer edge of the lampshade 200. The sealing ring 310 includes a mounting portion 311 and a sealing portion 312. The mounting portion 311 is located below the sealing portion 312, and the width of the sealing portion 312 is greater than the width of the mounting portion 311. The mounting portion 311 is adapted to the fixing groove 210, so that the mounting portion 311 can be inserted into the fixing groove 210, temporarily fixing the sealing ring 310 at the outer edge of the lampshade 200. The portion of the sealing portion 312 that protrudes from the mounting portion 311 in the width direction contacts the top surface of the border, making the sealing ring 310 relatively stable.

[0062] The side of the sealing portion 312 away from the mounting portion 311 is a semicircular arc surface. The sealing portion 312 is provided with an inner hole 313 with a circular or elliptical cross section, so that the sealing portion 312 has a large compression deformation capability.

[0063] The bottom edge of the lamp housing 100 is first bent upward 180 degrees, then bent horizontally outward 90 degrees, and finally bent downward 90 degrees, so that a limiting groove 120 structure is formed at the bottom edge of the lamp housing 100. The width of the limiting groove 120 is slightly larger than the width of the sealing portion 312, and the width of the sealing portion 312 is slightly larger than the width of the boundary.

[0064] When the lampshade 200 and the lamp housing 100 are covered with each other, the semicircular surface of the sealing portion 312 is pressed against the limiting groove 120. After the lampshade 200 and the lamp housing 100 are tightly covered, the sealing portion 312 is compressed and deformed, and fills the limiting groove 120, increasing the contact area between the sealing ring 310 and the lamp housing 100, improving the sealing reliability of the product, and making the sealing effect of the sealing ring 310 better. In addition, a plurality of outwardly protruding fastening strip structures are evenly formed on the semicircular surface of the sealing portion 312 and the mounting portion 311, and the length extension direction of the fastening strip structure is the same as the length extension direction of the sealing ring 310.

[0065] Furthermore, a plurality of clips 900 are installed at the top position of the edge of the lamp housing 100, and a slot 910 is formed below the boundary position of the lampshade 200. The clips 900 are movable clips or metal clips. By clamping the clips 900 in the slots 910, the connection between the lamp housing 100 and the lampshade 200 can be ensured. On the other hand, a stainless steel anti-fall chain can be connected between the lampshade 200 and the lamp housing 100 to facilitate customer maintenance. Reinforced edges and reinforcement ribs are provided at the position of the clips 900 in the slots 910 to improve the stability of the clips 900.

[0066] Example 2:

[0067] Reference Figure 11 This embodiment differs from the first embodiment in that it further comprises a connecting tube 430, a first one-way door 440, and a second one-way door 450. One end of the connecting tube 430 communicates with the end of the breathing tube 420 near the breathing cylinder 400, while the other end of the connecting tube 430 penetrates the sidewall of the breathing cylinder 400 and communicates with the second sealed space. The connecting tube 430 communicates with the second sealed space above the first salt mist adsorption layer 500, while the breathing tube 420 communicates with the second sealed space below the first salt mist adsorption layer 500.

[0068] A first one-way door 440 is mounted at one end of the connecting pipe 430 that communicates with the second sealed space. The first one-way door 440 is rotatably connected to the connecting pipe 430 and can only swing toward the connecting pipe 430, thereby allowing air in the second sealed space to enter the connecting pipe 430 while preventing air in the connecting pipe 430 from entering the second sealed space.

[0069] A second one-way door 450 is mounted at one end of the breathing tube 420 that connects to the second sealed space. The second one-way door 450 is rotatably connected to the breathing tube 420 and can only swing away from the breathing tube 420. This prevents air in the second sealed space from entering the breathing tube 420, while allowing air in the breathing tube 420 to enter the second sealed space.

[0070] When the piston plate 410 slides upward relative to the breathing tube 400, the volume of the second enclosed space increases, reducing the air pressure within the second enclosed space. Under the action of this pressure, the breathing holes 421 in the multiple breathing tubes 420 draw air from the outer periphery of the lamp housing 100 into the breathing tube 400. After passing through the first salt mist adsorption layer 500, the air enters the space between the piston plate 410 and the first salt mist adsorption layer 500. However, the air in the connecting tube 430 is blocked by the first one-way door 440 and cannot enter the second enclosed space, ensuring that all air entering the second enclosed space is filtered and adsorbed by the first salt mist adsorption layer 500.

[0071] When the piston plate 410 slides downward relative to the breathing tube 400, the volume of the second enclosed space decreases, causing the air pressure in the second enclosed space to increase. Under the action of the pressure, the air in the second enclosed space pushes the first one-way door 440 to rotate, allowing air with a low salt mist content to enter the connecting pipe 430 and connect to the breathing tube 420. It is then discharged through the multiple breathing holes 421 of the breathing tube 420, thereby allowing air with a low salt mist content to be present on the outer periphery of the lamp housing 100. This reduces the salt mist content on the outer periphery of the lamp housing 100 and the lampshade 200, thereby reducing the corrosion effect of the salt mist particles on the lamp housing 100 and the lampshade 200. This makes the lamp housing 100 and the lampshade 200 less susceptible to corrosion and increases the service life of the lighting lamp. During this process, due to the blocking effect of the second one-way door 450, the air with low smoke particle content will not pass through the first salt mist adsorption layer 500 and then pass through the second one-way door 450 to enter the breathing tube 420, thereby improving the efficiency of directly discharging the air with low smoke particle content from the connecting tube 430.

[0072] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
