Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a fish-attracting lamp. Background Technology

[0002] With social development and continuous advancements in science and technology, people's living standards are constantly improving, and the variety of lighting fixtures on the market is also increasing. One such fixture is the fish-attracting lamp, a tool that uses light to attract and trap fish. It is a primary piece of equipment in offshore fishing operations. Because the light from the fish-attracting lamp needs to shine into the water and has sufficient brightness, existing fish-attracting lamps generally use high-power LED chips as the light source, thus requiring a high-power driver. Furthermore, since fish-attracting lamps are mainly used for ocean fishing, seawater and sea breezes are corrosive. To prevent the driver from being damaged by corrosion, existing fish-attracting lamps typically house the driver inside a sealed power supply box. This box isolates the driver from the external seawater and sea breezes, thus preventing corrosion damage.

[0003] Because the power supply has a high power rating, when it is powered on and drives the light source to emit light, the rectifier bridge circuit, MOSFETs, and other electronic components of the power supply will generate a lot of heat. However, the power supply is sealed inside the power box housing, and in order to control costs, the power box housing of the fish-attracting lamp is generally made of plastic. Therefore, the large amount of heat generated when the power supply is powered on can only accumulate inside the power box housing and cannot be dissipated to the outside. As a result, the temperature of some electronic components of the power supply rises rapidly. After the power supply has been working for a period of time, these electronic components are prone to damage due to excessive temperature, which will cause the power supply to fail to drive the light source to emit light normally, seriously shortening the service life of the fish-attracting lamp. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a fish-attracting lamp that not only provides the power supply component with good corrosion resistance but also effectively dissipates heat from the electronic components, thereby preventing damage to the electronic components due to overheating and helping to extend the lifespan of the fish-attracting lamp.

[0005] A fish-attracting lamp according to an embodiment of the present invention includes a lamp body, a power supply box housing, and a power supply assembly. The lamp body is provided with a light source capable of emitting light when powered. The power supply box housing is mainly composed of a first housing, a second housing, and an intermediate heat-conducting component. One end of the intermediate heat-conducting component is connected to the inner surface of the first housing, and the other end of the intermediate heat-conducting component is connected to the inner surface of the second housing. The first housing, the second housing, and the intermediate heat-conducting component together form a receiving cavity. A first opening is formed on the surface of the first housing at a position corresponding to the intermediate heat-conducting component, and / or a second opening is formed on the surface of the second housing at a position corresponding to the intermediate heat-conducting component. The power supply assembly is disposed inside the receiving cavity. The power supply assembly includes a power supply substrate and a plurality of electronic components electrically connected to the power supply substrate. The power supply substrate is installed inside the receiving cavity and is electrically connected to the light source. At least one of the electronic components is arranged close to the inner wall of the intermediate heat-conducting component.

[0006] A fish-attracting lamp according to an embodiment of the present utility model has at least the following beneficial effects:

[0007] The power supply housing is configured to be mainly composed of a first housing, a second housing, and an intermediate heat-conducting component. The first housing and the second housing are connected to the two ends of the intermediate heat-conducting component in a one-to-one correspondence. The first housing, the second housing, and the intermediate heat-conducting component together enclose a receiving cavity. The power supply assembly is disposed inside the receiving cavity. At least one electronic component of the power supply assembly is arranged close to the inner wall of the intermediate heat-conducting component. A first opening is provided on the surface of the first housing at a position corresponding to the intermediate heat-conducting component, and / or a second opening is provided on the surface of the second housing at a position corresponding to the intermediate heat-conducting component. By adopting the above structure, when manufacturing fish-attracting lights, companies can arrange the electronic components that generate a large amount of heat when the power supply unit is powered on to be closely attached to the inner wall of the intermediate heat-conducting component. When the power supply unit drives the light source to emit light, these electronic components that generate a large amount of heat can quickly transfer the heat to the intermediate heat-conducting component. The intermediate heat-conducting component can then transfer the heat to the outside through the first opening and / or the second opening, thereby cooling down these electronic components and effectively preventing them from being damaged due to overheating. This allows the power supply unit to operate normally for a long time, thus helping to extend the service life of the fish-attracting light. Moreover, the power supply unit is housed inside the cavity of the power box shell, which can isolate the power supply unit from external air and water, thereby effectively preventing the power supply unit from being corroded and damaged, giving the power supply unit good corrosion resistance. In addition, the power box shell of this application only needs to use a material with good thermal conductivity to manufacture the intermediate heat-conducting component, instead of using a material with good thermal conductivity to manufacture the entire power box shell, which greatly reduces the production cost of the power box shell, thereby effectively reducing the production cost of the fish-attracting light and helping to enhance the social competitiveness of the company's products.

The fish-attracting lamp includes a lamp body 100, a power supply housing 200, and a power supply assembly 300. The lamp body 100 is provided with a light source capable of emitting light when powered. In this embodiment, the light source is an LED light-emitting chip installed at one end of the lamp body 100. The power supply housing 200 is located at the other end of the lamp body 100 away from the light source. The power supply housing 200 mainly includes a first housing 210, a second housing 220, and an intermediate heat-conducting component 230. The first housing 210, the second housing 220, and the intermediate heat-conducting component 230 can be joined together to form the power supply housing 200. One end of the intermediate heat-conducting component 230 is connected to the inner surface of the first housing 210, and the other end of the intermediate heat-conducting component 230 is connected to the inner surface of the second housing 220. The first housing 210, the second housing 220 and the intermediate heat-conducting component 230 together enclose a receiving cavity 240, which is a sealed chamber for installing the power supply assembly 300. A first opening 211 is provided on the surface of the first housing 210 at a position corresponding to the intermediate heat conductor 230, or a second opening 221 is provided on the surface of the second housing 220 at a position corresponding to the intermediate heat conductor 230; or the first opening 211 and the second opening 221 are provided on the surfaces of the first housing 210 and the second housing 220 at positions corresponding to the intermediate heat conductor 230 respectively; the power supply assembly 300 is disposed inside the receiving cavity 240, and the power supply assembly 300 includes a power supply substrate 310 and a plurality of electronic components 320 electrically connected to the power supply substrate 310; the power supply substrate 310 is installed inside the receiving cavity 240 and is electrically connected to the light source; wherein, at least one electronic component 320 is arranged close to the inner wall of the intermediate heat conductor 230.

[0036] In this embodiment, the fish-attracting lamp is configured such that the power supply housing 200 is mainly composed of a first housing 210, a second housing 220, and an intermediate heat-conducting component 300. The first housing 210 and the second housing 220 are connected to the two ends of the intermediate heat-conducting component 300 in a one-to-one correspondence. The first housing 210, the second housing 220, and the intermediate heat-conducting component 230 together enclose a receiving cavity 240. The power supply assembly 300 is disposed inside the receiving cavity 240. At least one electronic component 320 of the power supply assembly 300 is arranged close to the inner wall of the intermediate heat-conducting component 230. A first opening 211 is opened on the surface of the first housing 210 at a position corresponding to the intermediate heat-conducting component 230, and / or a second opening 221 is opened on the surface of the second housing 220 at a position corresponding to the intermediate heat-conducting component 230. By adopting the above structure, when manufacturing fish-attracting lamps, companies can arrange electronic components 320 that generate a lot of heat when the power supply component 300 is powered on to be closely attached to the inner wall of the intermediate heat-conducting component 230. For example, electronic components 320 such as rectifier bridge circuits and MOSFETs that generate a lot of heat when powered on can be closely attached to the inner wall of the intermediate heat-conducting component 230. When the fish-attracting lamp of this embodiment is powered on and emits light, the power supply assembly 300 drives the light source to emit light. The electronic components 320, which generate a large amount of heat during operation, can quickly transfer this heat to the intermediate heat-conducting component 230. The intermediate heat-conducting component 230 then dissipates the heat from the first opening 211 and / or the second opening 221 to the outside, thereby cooling the electronic components 320 and effectively preventing them from being damaged due to overheating. This allows the power supply assembly 300 to operate normally for a long time, thus helping to extend the lifespan of the fish-attracting lamp. Furthermore, the power supply assembly 300 is housed inside the receiving cavity 240 of the power supply housing 200, which isolates it from external air and water, thus providing… This design effectively prevents the power supply component 300 from being corroded or damaged, or from short-circuiting due to contact with water, thus giving the power supply component 300 excellent corrosion resistance. Furthermore, the power supply housing 200 of this application only requires the intermediate heat-conducting component 230 to be made of a material with good thermal conductivity. In this embodiment, the intermediate heat-conducting component 230 is made of aluminum alloy, giving it excellent thermal conductivity. This eliminates the need to use a material with good thermal conductivity to manufacture the entire power supply housing 200. The first housing 210 and the second housing 220 can still be manufactured using injection molding, significantly reducing the production cost of the power supply housing 200, thereby effectively reducing the production cost of the fish-attracting lamp and helping to enhance the social competitiveness of the company's products.

[0037] It should be noted that in the above embodiments, the intermediate heat-conducting component 230 is made of aluminum alloy. However, in other embodiments of this utility model, the intermediate heat-conducting component 230 can also be made of other materials with good thermal conductivity. Specifically, the intermediate heat-conducting component 230 is made of copper, which has good thermal conductivity, and the specific choice can be made according to actual needs.

[0038] To better protect the power assembly 300 from the power box housing 200, in some embodiments of this invention, a potting compound filling layer is provided inside the receiving cavity 240, filling the entire cavity 240. When the power assembly 300 is installed inside the receiving cavity 240 of the power box housing 200, the manufacturer can inject potting compound into the receiving cavity 240, thus filling the entire cavity 240. The potting compound then encapsulates the power assembly 300 and fills the gap between the power assembly 300 and the inner wall of the receiving cavity 240, forming the potting compound filling layer. By employing this method, even if external water penetrates into the receiving cavity 240, the water cannot reach the power assembly 300 encapsulated by the potting compound, thereby effectively protecting the power assembly 300 and further enhancing the protective performance of the power box housing 200. In this embodiment, the potting compound injected into the receiving cavity 240 can be epoxy resin potting compound, silicone potting compound, or polyurethane potting compound, depending on the actual needs. Since epoxy resin potting compounds, silicone potting compounds, or polyurethane potting compounds are all commercially available and are well-known technologies in the field, they will not be described in detail here.

[0039] Reference Figure 6 , Figure 7 , Figure 9 and Figure 10 To facilitate the injection of filler adhesive into the receiving cavity 240 of the power supply housing 200, in some embodiments of this invention, the side wall of the power supply housing 200 has at least one injection port 250 communicating with the interior of the receiving cavity 240. Specifically, there are two injection ports 250, located on the same side of the power supply housing 200. One injection port 250 is located on the side wall of the first housing 210, and the other injection port 250 is located on the side wall of the second housing 220. By adopting the above structure, when producing fish-attracting lights, the manufacturer can inject filler adhesive into the receiving cavity 240 of the power supply housing 200 through both injection ports 250, thereby filling the entire interior of the receiving cavity 240 and better encapsulating the power supply component 300.

[0040] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11In order to enable the intermediate heat conductor 230 to dissipate heat better, in some embodiments of this utility model, a first opening 211 is provided on the surface of the first housing 210 at a position corresponding to the intermediate heat conductor 230, and a second opening 221 is provided on the surface of the second housing 220 at a position corresponding to the intermediate heat conductor 230. An intermediate channel 231 is provided in the middle of the intermediate heat conductor 230, connecting the first opening 211 and the second opening 221. That is, the intermediate channel 231 runs through the entire intermediate heat conductor 230. One end of the intermediate channel 231 is connected to the first opening 211, and the other end of the intermediate channel 231 is connected to the second opening 221. The first opening 211, the intermediate channel 231 and the second opening 221 are connected in sequence to form a heat dissipation channel. A cooling fan 400 is installed inside the heat dissipation channel. By adopting the above structure, when the power supply assembly 300 is powered on and drives the light source to emit light, the electronic component 320, which is in close contact with the intermediate heat conductor 230, can quickly transfer heat to the intermediate heat conductor 230. The cooling fan 400 is powered on and drives air to flow continuously through the heat dissipation channel. The air continuously contacts the intermediate heat conductor 230 and carries away the heat of the intermediate heat conductor 230, so that the intermediate heat conductor 230 can dissipate heat quickly. This greatly improves the heat dissipation performance of the intermediate heat conductor 230 to the electronic component 320, which is in close contact with the intermediate heat conductor 230. As a result, the temperature of these electronic components 320 will not rise too high after long-term power-on operation, which helps to protect these electronic components 320 and thus extends the service life of the power supply assembly 300.

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 To prevent foreign objects from contacting or colliding with the power supply housing 200, in some embodiments of this invention, the light source is located at one end of the lamp body 100, and the power supply housing 200 is located at the end of the lamp body 100 away from the light source. The end of the lamp body 100 away from the light source has a protective cover 500, which is fitted over the outer periphery of the power supply housing 200 and connected to the lamp body 100. By adopting the above structure, using the protective cover 500 to enclose the power supply housing 200 effectively prevents foreign objects from contacting or colliding with the power supply housing 200, thereby preventing the power supply housing 200 from cracking and affecting its sealing performance.

[0042] To facilitate heat dissipation of the power supply housing 200, in some embodiments of this invention, a heat dissipation vent 510 is provided on the surface of the protective cover 500 at a position corresponding to the first opening 211 or the second opening 221. That is, when the first housing 210 faces the inner surface of the protective cover 500, a heat dissipation vent 510 corresponding to the first opening 211 of the first housing 210 is provided on the surface of the protective cover 500. Alternatively, when the second housing 220 faces the inner surface of the protective cover 500, a heat dissipation vent 510 corresponding to the second opening 221 of the second housing 220 is provided on the surface of the protective cover 500. By adopting the above structure, when the cooling fan 400 is powered on, outside air can quickly pass through the heat dissipation vent 510 on the surface of the protective cover 500 and flow into the heat dissipation channel, thereby cooling the intermediate heat-conducting component 230. Alternatively, when the cooling fan 400 is powered on, it can drive the air inside the heat dissipation channel to quickly pass through the heat dissipation vents 510 on the surface of the protective cover 500 and flow to the outside, thereby quickly carrying away the heat from the intermediate heat conductor 230 and cooling it down. By adopting the above structure, the power supply housing 200 can still have good heat dissipation performance.

[0043] To prevent foreign objects from contacting or colliding with the cooling fan 400 located inside the heat dissipation channel, in some embodiments of this invention, the protective cover 500 is provided with a protective mesh located at the heat dissipation opening 510. Specifically, the protective mesh is composed of multiple strips arranged at intervals. All strips are integrally molded with the protective cover 500. By adopting the above structure, the production and processing of the protective cover 500 is facilitated, which helps to reduce production costs. Moreover, by providing a protective mesh at the heat dissipation opening 510, it is possible to prevent foreign objects from passing through the heat dissipation opening 510 and contacting the cooling fan 400 located inside the heat dissipation channel, thus effectively protecting the cooling fan 400. At the same time, air can also flow quickly through the heat dissipation opening 510, thereby not affecting the heat dissipation of the power supply housing 200.

[0044] Reference Figure 3 , Figure 4 and Figure 5To prevent rainwater from passing through the heat dissipation vent 510 of the protective cover 500 and accumulating between the inner wall of the protective cover 500 and the outer peripheral wall of the power supply housing 200, a fish-attracting lamp in some embodiments of this utility model further includes a hollow guide shroud 600. That is, the guide shroud 600 is a component with an internal channel that runs through the entire guide shroud 600. The guide shroud 600 is located between the inner wall of the power supply housing 200 and the protective cover 500. The guide shroud 600 has a first end and a second end that are oppositely disposed. The first end of the guide shroud 600 is connected to the heat dissipation vent 510, and the second end of the guide shroud 600 is connected to the heat dissipation channel. The guide shroud 600 connects the heat dissipation vent 510 and the heat dissipation channel in series. By adopting the above structure, outside air can pass through the heat dissipation vent 510 and the air guide shroud 600 in sequence and flow to the heat dissipation channel, or the air inside the heat dissipation channel can pass through the air guide shroud 600 and the heat dissipation vent 510 without affecting the heat dissipation performance of the power supply housing 200. When rainwater or seawater splashes on the outer surface of the protective cover 500, the rainwater or seawater can flow along the heat dissipation vent 510 to the inside of the air guide shroud 600. The air guide shroud 600 guides the rainwater or seawater to flow to the heat dissipation channel and discharges it from the other end of the heat dissipation channel. The rainwater or seawater will not accumulate between the inner wall of the protective cover 500 and the outer peripheral wall of the power supply housing 200, thereby greatly reducing the penetration of rainwater or seawater into the receiving cavity 240 of the power supply housing 200, thus better protecting the power supply component 300.

[0045] In some embodiments of this invention, the first end of the flow guide 600 is connected to the inner wall of the protective cover 500, and the first end of the flow guide 600 covers the outer periphery of the heat dissipation port 510, while the second end of the flow guide 600 extends into the interior of the heat dissipation channel. By adopting the above structure, the flow guide 600 can better guide rainwater or seawater to the interior of the heat dissipation channel.

[0046] Reference Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12In some embodiments of this utility model, the first housing 210 is fitted over the upper part of the second housing 220. The upper part of the second housing 220 is provided with an upper periphery 222 arranged around the outer periphery of the second housing 220, and the lower part of the first housing 210 is provided with a lower periphery 212 arranged around the outer periphery of the first housing 210. The lower periphery 212 is fitted around the outer periphery of the upper periphery 222. By adopting the above structure, the first housing 210 is fitted over the upper part of the second housing 220. Even if rainwater or seawater from the outside splashes onto the first housing 210, the rainwater or seawater can flow down along the outer surface of the first housing 210 to the outer surface of the second housing 220, and then flow down along the outer surface of the second housing 220. It will not seep into the cavity 240 from the gap between the first housing 210 and the second housing 220, which greatly improves the waterproof performance of the power box housing 200.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention 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 invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
