Description

Technical Field

[0001] The present invention relates to a lamp, and particularly to a fish-aggregating lamp for underwater use. Background Art

[0002] The fish-aggregating lamp is one of the important tools in modern fishery and is a crucial factor for the catch. Most of the current traditional fish-aggregating lamps use high-wattage metal halide lamps. Although metal halide lamps can meet the requirements of fishing operations, they have many disadvantages in actual use. When using a metal halide lamp, a starter needs to be installed, and it takes a long time for it to start and reach the required brightness. After the metal halide lamp is turned off, it cannot be restarted immediately and needs to cool down before it can be turned on again, which often delays the time of fishermen. Generally, the service life of a metal halide lamp is 1000 - 3000h, which is relatively short. Moreover, the light emitted by the metal halide lamp contains ultraviolet rays, which can cause damage to the eyes and skin of fishery workers. Most importantly, the metal halide lamps used in traditional light sources gradually expose disadvantages such as high energy consumption and short service life. In recent years, they have been gradually transformed into LED fish-aggregating lamps. LED fish-aggregating lamps have the effects of saving energy consumption and improving the working environment. They also have characteristics such as a large irradiation range of the light source, sufficient brightness, firm and shock-resistant lamps, water-tight and pressure-resistant, and durable, and can be used to quickly start attracting fish schools. Currently, general deep-sea fish-aggregating lamps generally use LED modules with small power to emit light, which inevitably leads to problems such as small power of a single LED module, large size, small luminous flux, and small underwater irradiation distance of the fish-aggregating lamp. In the prior art, there are also some fish-aggregating lamps using high-power LED light sources, but the structures of these fish-aggregating lamps are relatively complex. Generally, they only have local side light emission and insufficient light brightness. And basically, when the light sources are arranged side by side on the side, they cannot achieve a 360° omnidirectional irradiation in the vertical circumference. At the same time, the overall light intensity is low, the irradiation distance is short, and the effective fish-aggregating range is small. Therefore, the underwater LED fish-aggregating lamps in the prior art still need to be improved. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention provides a fish-aggregating lamp for underwater use with a novel structure, which can achieve a 360° omnidirectional irradiation in the vertical axial circumference, has a large irradiation intensity, a long irradiation distance, and a large effective fish-aggregating range.

[0004] To solve this technical problem, the present invention adopts the following solution: An underwater fish-aggregating lamp, comprising a housing and a light-emitting component; the bottom diameter of the housing is larger than the top diameter and the housing is in an overall bullet shape, the vertical circumferential surface of the housing centered on the central axis is evenly divided into more than eight longitudinal lamp-position installation areas along the axial direction, a lamp position is provided at the bottom end of the housing, and at least one lamp position is provided on each longitudinal lamp-position installation area. The light-emitting component includes a plurality of first light-emitting units and a second light-emitting unit that match the number of lamp positions in each longitudinal lamp-position installation area. The second light-emitting unit is installed at the lamp position at the bottom end of the housing. Each first light-emitting unit is respectively connected to the lamp positions 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 at the same horizontal line position. Each first light-emitting unit includes a lamp holder, a lens lamp cover, and a COB module. The COB module is provided at the lamp position of the housing. The lens lamp cover is fixedly connected to the lamp position through the lamp holder and the lens lamp cover covers the COB module. The surface of the lens lamp cover close to the COB module is an inwardly concave incident surface and the surface of the lens lamp cover away from the light-emitting plate is an outwardly convex emitting surface. The light-emitting surface angle of the lens lamp cover is 45°-90°.

[0005] Further, the lamp positions on each longitudinal lamp-position installation area are arranged at intervals along the axial direction.

[0006] Further, the vertical circumferential surface of the housing is divided into more than eight even-numbered longitudinal lamp-position installation areas, and at least one lamp position on the longitudinal lamp-position installation areas on the opposite sides is at the same horizontal line position.

[0007] Furthermore, every two longitudinal lamp-position installation areas on the opposite sides are divided into a group of longitudinal lamp-position installation areas. The lamp positions in each group of longitudinal lamp-position installation areas are arranged alternately at intervals along the axial direction, and the longitudinal interval distance of each group is 10-41 cm.

[0008] Further, the lamp holder is provided with a through hole, a retaining ring extends out of the through hole, a retaining edge extends out of the lens lamp cover, and the retaining ring is connected to the retaining edge to limit the lens lamp cover from disengaging from the lamp holder.

[0009] Further, the first light-emitting unit further includes a protective frame. The protective frame is of a hollow structure and is fixedly provided on the housing or the lamp holder to cover the lens lamp cover for protecting the lens lamp cover.

[0010] Further, the housing includes a shell body and a conical top. The shell body and the conical top are of a split structure; the conical top is connected to the top of the shell body, and the lamp position is provided on the side surface of the shell body.

[0011] Furthermore, the second light-emitting unit includes a hollow protective cover, a lamp shade, a lamp holder, and at least two groups of LED lamp boards. An arc-shaped mounting surface recessed towards the top of the housing is provided at the lamp position at the bottom end of the housing. Each group of LED lamp boards is evenly arranged on the arc-shaped mounting surface. The lamp shade is fixedly arranged at the lamp position at the bottom end of the housing through the lamp holder and covers each group of LED lamp boards. The hollow protective cover is fixedly arranged at the bottom end of the housing to cover the lamp shade for protecting the lamp shade.

[0012] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows: By evenly arranging more than eight longitudinal lamp position installation areas on the circumferential surface of the housing, and setting the lamp positions in two adjacent longitudinal lamp position installation areas not at the same horizontal line position, and at the same time adopting a lens lamp shade structure for each first light-emitting unit, that is, the surface of the lens lamp shade close to the COB module is an inwardly concave incident surface and the surface of the lens lamp shade away from the light-emitting board is an outwardly convex emitting surface, so that each first light-emitting unit on the housing cooperates to achieve a 360° all-round illumination in the circumferential direction of the vertical axis of the housing. At the same time, each first light-emitting unit on the housing, in cooperation with the lens lamp shade, forms a multi-region light condensation superposition area with each adjacent first light-emitting unit, that is, the light intensity of the light illumination area emitted by each first light-emitting unit is enhanced by more than twice in the light condensation superposition area. The illumination intensity in the light superposition area is greatly enhanced, so that the illumination distance is far, and further, the effective fish collection range is enhanced in all directions and the range is increased. Additionally, the more the longitudinal lamp position installation areas are set (that is, the more the number of divided longitudinal lamp position installation areas), the larger the light superposition area is achieved, and the more lamp positions are set in the same longitudinal lamp position installation area, the light superposition area can also be effectively enhanced and increased. By arranging the lamp positions such that at least one lamp position on the longitudinal lamp position installation areas on the opposite sides is at the same horizontal line position, it can ensure that more light superposition areas are formed in each longitudinal section of the housing. By dividing every two longitudinal lamp position installation areas on the opposite sides into a group of longitudinal lamp position installation areas, the lamp positions in each group of longitudinal lamp position installation areas are alternately arranged at intervals along the axial direction, and the longitudinal interval distance of each group is 10 - 41 cm, so that each first light-emitting unit on the second longitudinal lamp position installation area in the longitudinal direction realizes a light superposition area in four directions of up, down, left, and right. When two or more lamp positions are set in the same longitudinal installation area, the adjacent three can form a three-fold light intensity superposition enhancement in the intersection area, making its illumination distance longer and further enhancing and increasing the effective fish collection range. The lamp of the present invention can be directly placed at the bottom of the water, and the heat can be taken away by the direct contact between the water flow and the housing, improving the service life of the lamp; the fish collection lamp is set in a bullet shape, and the streamlined surface makes it easier for the staff to operate up and down when fishing. The diameter of the bottom end of the housing is larger than that of the top end, so that the lamp can be stably placed in the sea water and is not easy to swing, and it can be widely promoted and applied.

The lamp positions on the longitudinal lamp position installation areas on the opposite sides are in the same horizontal line position. Every two longitudinal lamp position installation areas on the opposite sides are divided into a group of longitudinal lamp position installation areas. The lamp positions of each group of longitudinal lamp position installation areas are arranged alternately at intervals along the axis. The longitudinal interval distance of each group is 11 cm. The light-emitting component includes ten first light-emitting units 21 that match the number of lamp positions in each longitudinal lamp position installation area. Each first light-emitting unit 21 is respectively connected to the lamp positions in each longitudinal lamp position installation area and assembled with the housing 1 as a whole, and the lamp positions in adjacent two longitudinal lamp position installation areas are not in the same horizontal line position. Each first light-emitting unit 21 includes a lamp holder 211, a lens lamp cover 212, a COB module 213 and a protective frame 214. The COB module 213 is arranged on the lamp position of the housing 1. The lens lamp cover 212 is fixedly connected to the lamp position through the lamp holder 211, and the lens lamp cover 212 covers the COB module 213. The protective frame 214 is of a hollow structure. The protective frame 214 is fixedly arranged on the lamp holder 211 to cover the lens lamp cover 212 to protect the lens lamp cover 212. The surface of the lens lamp cover 212 close to the COB module 213 is an inwardly concave incident surface, and the surface of the lens lamp cover 212 far from the light-emitting board 213 is an outwardly convex emitting surface. The light-emitting surface angle of the lens lamp cover 212 is 60°.

[0016] The lamp holder 211 is provided with a through hole, and a retaining ring extends out of the through hole. The lens lamp cover 212 extends out of a retaining edge, and the retaining ring is connected to the retaining edge to prevent the lens lamp cover 212 from disengaging from the lamp holder 211. The housing 1 includes a shell and a conical top, and the shell and the conical top are of a split structure; the conical top is connected to the top of the shell, and the lamp position is arranged on the side surface of the shell. The light-emitting assembly further includes a second light-emitting unit 22. The bottom end of the housing 1 is provided with a lamp position, and the second light-emitting unit 22 is installed on the lamp position at the bottom end of the housing 1. The second light-emitting unit 22 includes a hollow protective cover, a lamp cover, a lamp holder, and three groups of LED lamp boards. An arc-shaped mounting surface recessed towards the top end of the housing is arranged on the lamp position at the bottom end of the housing. Each group of LED lamp boards is evenly arranged on the arc-shaped mounting surface. The lamp cover is fixedly arranged on the lamp position at the bottom end of the housing 1 through the lamp holder, and the lamp cover covers each group of LED lamp boards. The hollow protective cover is fixedly arranged on the bottom end of the housing 1 to cover the lamp cover for protecting the lamp cover.

[0017] Reference Figure 5 and Figure 6 , when the operating power of the COB module 213 of the first light-emitting unit 21 is 250W, the light-emitting surface angle of its lens lamp cover 212 is 60°. The irradiation distance of a single COB module 213 is 52.6 meters (the illuminance is 10 lux at this time). The light-emitting surface angle of the double light irradiation superposition area formed by the overall 360° light-emitting design is 24°, and the irradiation distance of the COB module 213 in the double light irradiation superposition area is 73.6 meters (the illuminance is 10 lux at this time). When two or more lamp positions are arranged in a single longitudinal lamp position installation area, the three adjacent ones can form a triple light intensity superposition enhancement in the intersection area, and the irradiation distance of the COB module 213 in the triple light irradiation superposition area is 85.6 meters (the illuminance is 10 lux at this time), realizing a substantial and effective extension of the irradiation distance.

[0018] When the vertical circumferential surface of the housing is divided into more longitudinal lamp position installation areas and more lamp positions are arranged in the longitudinal lamp position installation areas to cooperate with the COB modules arranged in the first light-emitting unit, more and larger range light irradiation area superpositions can be realized, and more adjacent three can form triple light intensity superposition areas in the intersection area to enhance the irradiation of the lamp.

[0019] In the above embodiments, the light-emitting surface angle of the lens lamp cover is preferably 45°-90°. When the light-emitting surface angle of the lens lamp cover is 45°-50°, high-concentration light superposition can be achieved, and the irradiation distance of the light superposition area is farther than that of the conventional one. It can be achieved that the vertical circumferential surface of the housing is divided into more than eight longitudinal lamp position installation areas. According to the size of the fish-attracting lamp made, more longitudinal lamp position installation areas can be set, which can effectively enhance and increase the light superposition area. When the vertical circumferential surface of the housing is divided into an even number of more than eight longitudinal lamp position installation areas, at least one lamp position on the longitudinal lamp position installation areas on the opposite sides is at the same horizontal line position. Each two longitudinal lamp position installation areas on the opposite sides are divided into a group of longitudinal lamp position installation areas. The longitudinal interval distance between the lamp positions of each group of longitudinal lamp position installation areas arranged alternately along the axis is preferably 10-41 cm. The housing is set in a bullet shape. Using this streamline surface makes it easier for the staff to operate up and down when fishing. It can also be set in a conventional shape. The housing can be made of magnesium alloy, which reduces the overall weight of the lamp compared with the conventional aluminum alloy, has a higher thermal conductivity index, effectively improves the service life of the lamp, and effectively reduces the load problem during use. The protective frame of the first light-emitting unit can also be directly fixed on the housing. The second light-emitting unit can also be provided with a single group of LED lamp boards. The second light-emitting unit can also adopt a structure with two or more groups of LED lamp boards combined with an arc-shaped installation surface, so that the bottom of the housing emits a light intensity with multiple light superpositions, effectively enhancing the light intensity and light range at the bottom of the fish-attracting lamp, and improving the irradiation distance downward.

[0020] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them are within the protection scope of the present invention.
