Description

Technical Field

[0001] This utility model relates to lighting fixtures, and in particular to a novel underwater fish-attracting lighting fixture. Background Technology

[0002] Fish-attracting lights are an essential tool in modern fisheries, playing a crucial role in fish catches. Underwater fish-attracting lights are suitable for various fishing environments, including but not limited to aquaculture farms, deep-sea fishing, and nighttime fishing in rivers and lakes. They primarily attract deep-water fish by drawing them towards the light source, thus luring phototactic fish. Generally, underwater fish-attracting lights have high power, requiring correspondingly larger heat sinks. Currently, underwater LED fish-attracting lights mimic the structure of underwater metal halide lamps, replacing the light source with LED chips. They are encased in transparent materials like glass or PC to isolate them from seawater, but the heat dissipation is still unsatisfactory. This is because the heat generated by the LED light source module must be transferred through the air inside the lamp cover to the glass, and then from the glass to the seawater, limiting the power output. To increase the power of underwater fish-attracting lights, the heat sink needs to be larger. However, a larger heat sink increases water resistance, making the light fixture easily misaligned by currents. Conversely, a smaller heat sink results in poor heat dissipation and a shorter lifespan. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a new type of underwater fish-attracting lamp with good heat dissipation effect, which can meet the heat dissipation of high-power light source boards and extend the service life of the light source boards.

[0004] To solve this technical problem, the present invention adopts the following solution: A novel underwater fish-attracting lamp includes a lamp body, which includes a lampshade, an upper cover, a lower cover, a radiator, and one or more light source plates. It also includes an upper waterproof annular rubber ring and a lower waterproof annular rubber ring. The radiator is a hollow columnar radiator, with each set of light source plates evenly distributed on the outer surface of the radiator. The lampshade is fitted onto the radiator and the light source plates. The upper and lower waterproof annular rubber rings are respectively fitted onto the upper and lower ends of the radiator and the lampshade, forming a closed cavity between the outer wall of the radiator, the inner wall of the lampshade, and the upper and lower waterproof annular rubber rings. The inner walls at both ends of the radiator extend towards the center, providing upper and lower mounting positions adapted to the upper and lower covers. The upper and lower covers respectively press the upper and lower waterproof annular rubber rings and fix them to the mounting positions at both ends of the radiator. The inner wall of the radiator has fine toothed protrusions, with the upper waterproof annular rubber ring facing the upper end of the radiator. The upper end of the heat sink and the upper end of the lamp cover are respectively provided with a first annular groove and a second annular groove that are adapted to the upper end of the heat sink and the upper end of the lamp cover. The upper end of the heat sink and the upper end of the lamp cover are respectively embedded in the first annular groove and the second annular groove of the upper waterproof annular rubber ring. The lower waterproof annular rubber ring is respectively provided with a third annular groove and a fourth annular groove that are adapted to the lower end of the heat sink and the lower end of the lamp cover. The lower end of the heat sink and the lower end of the lamp cover are respectively embedded in the third annular groove and the fourth annular groove of the lower waterproof annular rubber ring. The upper cover is provided with a first mounting groove that is adapted to the upper waterproof annular rubber ring on the side facing the upper waterproof annular rubber ring. The upper waterproof annular rubber ring is embedded in the first mounting groove of the upper cover. The lower cover is provided with a second mounting groove that is adapted to the lower waterproof annular rubber ring on the side facing the lower waterproof annular rubber ring. The lower waterproof annular rubber ring is embedded in the second mounting groove of the lower cover.

[0005] In a further improvement, the upper cover and the lower cover extend radially outward to form a fixing ring, and multiple locking positioning support rods are evenly distributed between the fixing rings of the upper cover and the lower cover.

[0006] In a further improvement, the first mounting groove of the upper cover is provided with a first annular boss facing the upper waterproof annular rubber ring in the middle, and the upper waterproof annular rubber ring is provided with a first annular groove that matches the first annular boss. The second mounting groove of the lower cover is provided with a second annular boss facing the lower waterproof annular rubber ring in the middle, and the lower waterproof annular rubber ring is provided with a second annular groove that matches the second annular boss.

[0007] In a further improvement, the first annular boss of the upper cover has a trapezoidal cross-section, and the second annular boss of the lower cover has a trapezoidal cross-section.

[0008] As a further improvement, the light source board is a COB lamp board.

[0009] In a further improvement, the lampshade can be any one of a PC transparent optical tube, a tempered glass tube, or an acrylic tube.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By forming a closed cavity between the radiator, lampshade, upper waterproof annular rubber ring, and lower waterproof annular rubber ring, and simultaneously providing upper and lower mounting positions extending towards the center at both ends of the radiator to match the upper and lower covers, the upper and lower covers respectively press the upper and lower waterproof annular rubber rings and are fixedly connected to the mounting positions at both ends of the radiator, so that the inner cavity of the radiator cavity achieves the maximum cavity design in a lamp of the same size, thereby enabling the radiator cavity to achieve maximum water flow heat exchange and heat dissipation, improving the heat dissipation effect of the radiator. Furthermore, the fine toothed protrusions on the inner wall of the radiator increase the resistance of water flow in the hollow cavity of the radiator, increasing the water flow residence time. Combined with the maximized inner cavity, this further improves the heat dissipation effect and can meet the heat dissipation requirements of high-power light source boards, thereby extending the service life of high-power light source boards. The upper end of the heat sink and the upper end of the lampshade are respectively embedded into the first and second annular grooves of the upper waterproof annular rubber ring, and the lower end of the heat sink and the lower end of the lampshade are respectively embedded into the third and fourth annular grooves of the lower waterproof annular rubber ring. Simultaneously, the upper waterproof annular rubber ring is embedded in the first mounting groove of the upper cover, and the lower waterproof annular rubber ring is embedded in the second mounting groove of the lower cover, creating a compression seal between the upper and lower covers and the lampshade for waterproofing. A first annular boss is provided in the center of the first mounting groove of the upper cover to mate with the first annular groove of the upper waterproof annular rubber ring. The second mounting groove of the lower cover is equipped with a second annular boss that cooperates with the second annular groove of the lower waterproof annular rubber ring, so that the lamp cover, upper cover, lower cover, upper waterproof annular rubber ring and lower waterproof annular rubber ring form a three-sided waterproof structure, which makes the waterproofing tighter when the water pressure is high. The trapezoidal tapered structure between the upper waterproof annular rubber ring and the lower waterproof annular rubber ring and the upper cover and the lower cover further enhances the tightness of partial deformation, and further ensures the overall sealing of the closed cavity formed between the outer wall of the radiator, the inner wall of the lamp cover and the upper waterproof annular rubber ring and the lower waterproof annular rubber ring, which can be widely used.
