Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a marine lighting lamp. Background Technology

[0002] Overhead lighting is commonly used in various types of indoor and outdoor areas of ships. Due to the unique marine environment, these areas are generally humid and salty. Therefore, the internal environment of the lighting fixtures needs to be sealed to prevent humid and salty air from entering and causing corrosion to the internal structure.

[0003] Typically, lighting fixtures use a translucent lampshade to cover a lamp housing containing the lamp tube. A sealing ring is installed between the lamp housing and the lampshade to achieve a sealing effect. However, during the installation of the sealing ring, due to its flexibility, it is easy for the lampshade to come into contact with or be squeezed during the installation process. This can cause the sealing ring to shift or deform irregularly, thus affecting its sealing effect. Utility Model Content

[0026] Reference Figure 1-4 A marine lighting lamp includes a lamp housing 100, a lamp shade 200, a lamp body assembly 300, and a sealing ring 400.

[0027] The lamp housing 100 has an opening facing downwards, while the lamp shade 200 has an opening facing upwards. The bottom edge of the lamp housing 100 and the top edge of the lamp shade 200 overlap each other, and the lamp housing 100 and lamp shade 200 are detachably connected. A sealing ring 400 is fitted and installed at the overlapping position of the lamp housing 100 and lamp shade 200, forming a first sealed space between them. The surface treatment of the lamp housing 100 uses anti-corrosion outdoor powder coating, greatly improving the product's corrosion resistance. The lamp shade 200 is made of flame-retardant PC injection molding, meeting marine corrosion protection requirements, and the inner surface of the lamp shade 200 is designed with anti-glare properties.

[0028] The lamp assembly 300 includes a mounting plate 310, a lamp tube 320, and a lamp holder 330. The mounting plate 310 is mounted on the inner top of the lamp housing 100 via angle brackets, positioning it between the lamp housing 100 and the lamp shade 200. The length and width dimensions of the mounting plate 310 are smaller than the corresponding dimensions within the lamp housing 100, creating a gap between the mounting plate 310 and the inner wall of the lamp housing 100 to allow for airflow between the top and bottom of the mounting plate 310. The mounting plate 310 is made of stamped steel with a white powder coating, significantly enhancing the reflectivity of the lamp tube 320 and achieving a high lumen output.

[0029] Both ends of the lamp tube 320 are equipped with lamp holders 330, which are installed on the ends of the mounting plate 310, so that the lamp tube 320 and the mounting plate 310 are fixedly connected. The light emitted by the lamp tube 320 passes through the lamp cover 200 below and is emitted to the outside to achieve the purpose of illumination.

[0030] The lamp housing 100 is equipped with a connector 130. The cable supplying power and control signals to the lamp tube 320 is connected to the lamp holder 330 inside the lamp housing 100 through the connector 130. The lamp holder 330 is connected to the end cap of the lamp tube 320 to realize the cable connection of the lamp tube 320. The connector 130 can be a waterproof connector made of plastic, which greatly reduces the product cost.

[0031] The sealing ring 400 includes a mounting portion 410 and a sealing portion 420. The mounting portion 410 and the sealing portion 420 are integrally formed and connected. The sealing ring 400 is integrally formed by extruding silicone strips and has moderate hardness. The mounting portion 410 is located below the sealing portion 420, and...

[0032] The outer peripheral edge of the lampshade 200 protrudes outward to form a wider boundary. A fixing groove 210 is formed on the top surface of the boundary, and the fixing groove 210 is arranged around the outer peripheral edge of the lampshade 200. The mounting part 410 is adapted to the fixing groove 210, so that the mounting part 410 can be inserted into the fixing groove 210, temporarily fixing the sealing ring 400 at the outer peripheral edge of the lampshade 200. The width of the sealing part 420 is greater than the width of the mounting part 410, and both sides of the sealing part 420 protrude from the mounting part 410 in the width direction. The bottom surface of the parts of the sealing part 420 that protrude from the mounting part 410 abuts against the top surface of the boundary, making the sealing ring 400 more stable.

[0033] The side of the sealing part 420 away from the mounting part 410 is an arc surface 421. The sealing part 420 has an inner hole 422. The cross-section of the inner hole 422 is circular or elliptical, which gives the sealing part 420 a large compressive deformation capacity.

[0034] The bottom edge of the lamp housing 100 is first bent upwards at a certain arc angle of 180 degrees, then bent outwards horizontally at a certain arc angle of 90 degrees, the horizontally extended portion being the extension edge 120. Finally, it is bent downwards at a certain arc angle of 90 degrees, thus forming a limiting groove 110 structure at the bottom edge of the lamp housing 100, that is, the position below the extension edge 120 is the limiting groove 110. It can be understood that the above three bending processes can be performed separately, two can be performed together, or all three can be performed simultaneously. The width of the limiting groove 110 is slightly larger than the width of the sealing part 420, and the width of the sealing part 420 is slightly larger than the width of the boundary. The upward bending angle of the bottom edge of the lamp housing 100 can be selected between 90 degrees and 180 degrees. The downward bending angle of the edge of the extension edge 120 can also be selected between 45 degrees and 90 degrees.

[0035] When the lampshade 200 and the lamp housing 100 are closed together, the arc surface 421 of the sealing part 420 presses against the limiting groove 110. After the lampshade 200 and the lamp housing 100 are tightly closed, the sealing part 420 is compressed and deformed, and fills the limiting groove 110, increasing the contact area between the sealing ring 400 and the lamp housing 100, improving the sealing reliability of the product, and making the sealing effect of the sealing ring 400 better.

[0036] Furthermore, multiple outwardly protruding ridges 430 are uniformly formed on the arc surface 421 of the sealing portion 420 and the mounting portion 410, and the ridges 430 are arranged parallel to each other. The length extension direction of the ridges 430 is the same as the length extension direction of the sealing ring 400. The cross-section of the ridges 430 is semi-circular, and the semi-circular arc surface of the ridges 430 faces outward. The overall width of the mounting portion 410 plus the ridges 430 on both sides is greater than the width of the fixing groove 210, and the width of the mounting portion 410 is less than the width of the fixing groove 210, so that the mounting portion 410 can be easily inserted into the fixing groove 210 while ensuring the sealing performance of the sealing ring 400.

[0037] Furthermore, multiple stainless steel clips 510 are installed at the top edge of the lamp housing 100 to meet outdoor corrosion resistance requirements. A groove 220 is formed below the boundary of the lamp shade 200. The clips 510 are movable clips or metal clips. Locking the clips 510 into the groove 220 ensures a stable connection between the lamp housing 100 and the lamp shade 200. On the other hand, a stainless steel anti-fall chain 500 connects the lamp shade 200 and the lamp housing 100, and also connects the lamp housing 100 and the mounting plate 310. The anti-fall chain 500 is formed by two or more elastic buckles connected in series, facilitating customer maintenance. Reinforcing edges and reinforcing ribs are provided in the groove 220 corresponding to the clips 510 to improve the stability of the clips 510 when engaged.

[0038] Both sides of the lamp holder 330 are provided with elastic hooks 331. These hooks 331, utilizing the properties of their material, possess a certain degree of deformation and recovery ability, i.e., elasticity. The top of the lamp holder 330 protrudes to form a limiting edge 332. The mounting plate 310 has through-holes 311 at the corresponding positions for mounting the lamp holder 330. When installing the lamp holder 330, it is passed through the through-holes 311 from top to bottom. After the elastic hooks 331 deform and pass through the through-holes 311, the limiting edge 332 abuts against the top surface of the mounting plate 310, and the elastic hooks 331 return to their original shape and lock in place. In other words, the edge of the through-hole 311 of the mounting plate 310 is engaged between the elastic hooks 331 and the limiting edge 332, thus fixing the lamp holder 330 to the mounting plate 310 in a relatively fixed connection. This facilitates installation and allows for disassembly.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
