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 one of the most important tools in modern fisheries, playing a crucial role in fish catches. Most traditional fish-attracting lights currently use high-wattage metal halide lamps. While these lamps can meet the needs of fishing operations, they have many drawbacks in practical use. They require a starter, and starting and reaching the desired brightness takes a long time. After being turned off, they cannot be immediately restarted; they need time to cool down before being turned on again, often wasting fishermen's time. The typical lifespan of a metal halide lamp is only 1000-3000 hours, which is relatively short. Furthermore, the light emitted by metal halide lamps contains ultraviolet rays, which can damage the eyes and skin of fishermen. Most importantly, the traditional metal halide lamps are increasingly showing drawbacks such as high energy consumption and short lifespan. In recent years, LED fish-attracting lights have been developed. LED fish-attracting lights save energy, improve the working environment, and also feature a larger illumination range, sufficient brightness, robust and shock-resistant design, watertight pressure resistance, and durability, making them suitable for quickly attracting fish schools. Current deep-sea fish-attracting lights generally use low-power LED modules for illumination. This inevitably leads to problems such as low power and large size of individual LED modules, low luminous flux, and short underwater illumination distance. While some existing technologies use high-power LED light sources, these lights have complex structures, generally only emit light from localized sides, resulting in insufficient brightness. Furthermore, they are typically arranged side-by-side with side-mounted light sources, failing to achieve 360° omnidirectional illumination. Additionally, the overall light intensity is low, the illumination distance is short, and the effective fish-attracting range is small. Therefore, current underwater LED fish-attracting lights still require improvement. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a novel underwater fish-attracting lamp with a novel structure, which can achieve 360° all-round illumination along the vertical axis, with high illumination intensity, long illumination distance, and large effective fish-attracting range.

[0004] To solve this technical problem, the present invention adopts the following solution: a novel underwater fish-attracting lamp, comprising a housing and a light-emitting component; the housing is elongated, and the vertical circumferential surface of the housing centered on the central axis is divided into eight or more longitudinal lamp position installation areas along the axial direction, with at least one lamp position in each longitudinal lamp position installation area; the light-emitting component includes multiple first light-emitting units matching the number of lamp positions in each longitudinal lamp position installation area; each first light-emitting unit is connected to the lamp position in each longitudinal lamp position installation area and assembled with the housing as a whole, and the lamp positions in two adjacent longitudinal lamp position installation areas are not on the same horizontal line; each first light-emitting unit includes a lamp holder, a lens cover, and a lamp plate; the lamp plate is located on the lamp position in the housing; the lens cover is fixedly connected to the lamp position via the lamp holder and covers the lamp plate; the side of the lens cover near the lamp plate is a concave incident surface and the side of the lens cover away from the COB module is a convex exiting surface; the light-emitting surface angle of the lens cover is 45°-90°.

[0005] Furthermore, each lamp position in each longitudinal lamp position installation area is arranged at intervals along the axial direction.

[0006] Furthermore, the vertical circumferential surface of the outer casing is divided into an even number of eight or more longitudinal lamp mounting areas, and at least one lamp is located on the same horizontal line in the longitudinal lamp mounting areas on opposite sides.

[0007] Furthermore, each pair of longitudinal lamp installation areas on opposite sides is divided into a group of longitudinal lamp installation areas. The lamps in each group of longitudinal lamp installation areas are arranged alternately along the axial direction, with a longitudinal interval of 10-41cm between each group.

[0008] Furthermore, the bottom diameter of the outer shell is larger than the top diameter, making the outer shell bullet-shaped overall.

[0009] Furthermore, the lamp holder is provided with a through hole, from which a retaining ring extends, and the lens cover extends with a retaining edge. The retaining ring and the retaining edge are connected to prevent the lens cover from detaching from the lamp holder.

[0010] Furthermore, the first light-emitting unit also includes a protective frame, which is a hollow structure. The protective frame is fixed on the outer shell or lamp holder and covers the lens cover to protect the lens cover.

[0011] Furthermore, the outer casing includes a housing and a conical top, with the housing and the conical top being a split structure; the conical top is connected to the top of the housing, and the lamp position is located on the side of the housing.

[0012] Furthermore, the light-emitting component also includes a second light-emitting unit, and the bottom of the housing is provided with a lamp position, and the second light-emitting unit is installed on the lamp position at the bottom of the housing.

[0013] Furthermore, the second light-emitting unit includes a hollow protective cover, a lampshade, a lamp holder, and at least two sets of LED light panels. The lamp position at the bottom of the housing is provided with an arc-shaped mounting surface that is recessed towards the top of the housing. Each set of LED light panels is arranged on the arc-shaped mounting surface. The lampshade is fixed to the lamp position at the bottom of the housing via the lamp holder and covers each set of LED light panels. The hollow protective cover is fixed to the bottom of the housing and covers the lampshade to protect it.

[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By evenly distributing eight or more longitudinal lamp mounting areas on the circumferential surface of the outer casing, and ensuring that the lamp positions within adjacent longitudinal lamp mounting areas are not on the same horizontal line, and by employing a lens cover structure for each first light-emitting unit (i.e., the side of the lens cover near the lamp panel is a concave incident surface, and the side of the lens cover away from the COB module is a convex exit surface), the first light-emitting units on the outer casing cooperate to achieve 360° omnidirectional illumination along the vertical circumference of the outer casing. Furthermore, the cooperation of the lens cover with each first light-emitting unit on the outer casing... The lower and adjacent first light-emitting units form a multi-region light-focusing superposition area, so that the light intensity of the area illuminated by each first light-emitting unit is more than twice that of the superposition area. The greatly enhanced illumination intensity of the superposition area results in a longer illumination distance, thereby enhancing and increasing the effective fish-attracting range in multiple directions. In addition, the more longitudinal light-position installation areas set (i.e., the more segmented longitudinal light-position installation areas), the larger the superposition area of ​​illumination is achieved. Furthermore, the more light positions set in the same longitudinal light-position installation area, the more effectively the superposition area of ​​illumination is enhanced and increased. By arranging the light positions such that at least one light position is located on the same horizontal line in the longitudinal light-position installation areas on opposite sides, it can be ensured that more superposition areas of illumination are formed in each longitudinal segment of the shell. By dividing each pair of opposing longitudinal light installation areas into a group, and arranging the lights in each group alternately along the axial direction with a longitudinal spacing of 10-41cm, the first light-emitting unit in each of the second longitudinal light installation areas achieves a superimposed illumination area in four directions: up, down, left, and right. When two or more lights are set in the same longitudinal installation area, the three adjacent lights can form a three-fold superimposed light intensity in the intersecting areas, resulting in a longer illumination distance and further enhancing the effective fish-attracting range. This utility model's light fixture can be placed directly on the bottom of the water, with the water flow directly contacting the outer shell to dissipate heat and improve the lifespan of the light fixture. The bullet-shaped fish-attracting light's streamlined surface makes it easier for workers to operate it up and down during fishing. The bottom diameter of the outer shell is larger than the top diameter, allowing the light fixture to be placed stably in seawater without easily swaying, making it widely applicable.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] refer to Figures 1-6 The preferred embodiment of this novel underwater fish-attracting lamp includes a housing 1 and a light-emitting component. The housing 1 is elongated, with the bottom diameter larger than the top diameter, giving the housing 1 a bullet-like shape. The vertical circumferential surface of the housing 1, centered on its central axis, is divided into ten longitudinal lamp-positioning areas along the axial direction. Each longitudinal lamp-positioning area occupies a 36° fan-shaped area, and each longitudinal lamp-positioning area has one lamp position. The lamp positions in opposite longitudinal lamp-positioning areas are positioned at the same horizontal level. Every two opposite longitudinal lamp-positioning areas form a group of longitudinal lamp-positioning areas. The lamp positions in each group of longitudinal lamp-positioning areas are arranged alternately along the axial direction, with a longitudinal interval of 11 cm between each group. The light-emitting component includes ten first light-emitting units 21, each matching the number of lamp positions in each longitudinal lamp-positioning area. The first light-emitting unit 21 is connected to the lamp position in each longitudinal lamp position installation area and assembled with the outer casing 1 as a whole. The lamp positions in two adjacent longitudinal lamp position installation areas are not on the same horizontal line. Each first light-emitting unit 21 includes a lamp holder 211, a lens lamp cover 212, a lamp plate 213 and a protective frame 214. The lamp plate 213 is set on the lamp position of the outer casing 1. The lens lamp cover 212 is fixedly connected to the lamp position via the lamp holder 211 and covers the lamp plate 213. The protective frame 214 has a hollow structure. The protective frame 214 is fixed on the lamp holder 211 and covers the lens lamp cover 212 to protect it. The side of the lens lamp cover 212 near the lamp plate 213 is a concave incident surface and the side of the lens lamp cover 212 away from the COB module 213 is a convex exit surface. The light-emitting surface angle of the lens lamp cover 212 is 60°.

[0023] The lamp holder 211 has a through hole, from which a retaining ring extends. The lens lamp cover 212 extends into a retaining edge, and the retaining ring connects with the retaining edge to prevent the lens lamp cover 212 from detaching from the lamp holder 211. The outer shell 1 includes a shell and a conical top, which are detachable. The conical top is connected to the top of the shell, and the lamp position is located on the side of the shell. The light-emitting component also includes a second light-emitting unit 22. The bottom of the outer shell 1 has a lamp position, and the second light-emitting unit 22 is installed at the lamp position at the bottom of the outer shell 1. The second light-emitting unit 22 includes a hollow protective cover, a lamp cover, a lamp holder, and three sets of LED lamp panels. The lamp position at the bottom of the outer shell has an arc-shaped mounting surface that is recessed towards the top of the outer shell. Each set of LED lamp panels is evenly distributed on the arc-shaped mounting surface. The lamp cover is fixed to the lamp position at the bottom of the outer shell 1 via the lamp holder and covers each set of LED lamp panels. The hollow protective cover is fixed to the bottom of the outer shell 1 and covers the lamp cover to protect it.

[0024] refer to Figure 5 and Figure 6 When the COB module 213 of the first light-emitting unit 21 operates at a power of 250W, the light-emitting surface angle of its lens cover 212 is 60°. The illumination distance of a single COB module 213 is 52.6 meters (with an illuminance of 10 lux). The overall 360° light-emitting design creates a double-light-overlapping area with a light-emitting surface angle of 24°, resulting in an illumination distance of 73.6 meters for the COB module 213 within this double-light-overlapping area (with an illuminance of 10 lux). When two or more lamp positions are installed in a single longitudinal lamp position area, the three adjacent lamps can form a triple-light-intensity superposition in the intersection area, increasing the illumination distance of the COB module 213 within this triple-light-overlapping area to 85.6 meters (with an illuminance of 10 lux), thus significantly extending the illumination distance.

[0025] When the vertical circumferential surface of the outer shell is divided into more longitudinal lamp mounting areas and more lamps are set in the longitudinal lamp mounting areas, the COB module set with the first light-emitting unit can achieve more and larger range of illumination areas superimposed, which can form more adjacent three areas that can form a three-fold light intensity superposition area at the intersection to enhance the illumination of the lamp.

[0026] In the above embodiments, the light-emitting surface angle of the lens cover is preferably 45°-90°. When the light-emitting surface angle is 45°-50°, high-concentration light superposition can be achieved, resulting in a longer illumination distance than conventional light superposition areas. The vertical circumferential surface of the outer shell can be divided into eight or more longitudinal lamp installation areas. Depending on the size of the fish-attracting lamp, more longitudinal lamp installation areas can be set, effectively enhancing and increasing the light superposition area. When the vertical circumferential surface of the outer shell is divided into an even number of eight or more longitudinal lamp installation areas, at least one lamp position is positioned on the same horizontal line in each opposing longitudinal lamp installation area. Every two opposing longitudinal lamp installation areas form a group of longitudinal lamp installation areas. The longitudinal interval between the lamp positions in each group of longitudinal lamp installation areas, arranged alternately along the axial direction, is preferably 10-41 cm. The bullet-shaped outer shell utilizes a streamlined surface for easier up-and-down operation by fish handlers. A conventional shape is also possible. The shell can be made of magnesium alloy, reducing the overall weight of the lamp compared to conventional aluminum alloy, while also increasing its thermal conductivity, effectively extending its lifespan and reducing the load during use. The protective frame of the first light-emitting unit can be directly fixed to the outer shell. The second light-emitting unit can be equipped with a single LED panel, or it can use two or more LED panels with a curved mounting surface, resulting in a multiplied light intensity emanating from the bottom of the shell, effectively enhancing the light intensity and range at the bottom of the fish-attracting lamp and increasing the downward beam distance.

[0027] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
