Description

Technical Field

[0001] This utility model relates to the field of sea sweeping light technology, and in particular to a focusing projection device for a high-power LED sea sweeping light. Background Technology

[0002] The focusing projection device of a high-power LED sea sweeping light is an optical device used to converge and project the light emitted by the LED light source to achieve long-distance, small-angle, high-intensity illumination.

[0003] The existing high-power LED sea sweeping light's focusing projection device uses a reflector and a convex lens to concentrate the scattered light emitted by the LED, allowing the light to be projected in a preset direction, preventing the light from spreading in useless directions, and thus improving the projection distance.

[0004] However, in practical applications, the existing high-power LED sea sweeping lights typically use aluminum substrates for heat dissipation. The thermal conductivity is limited by the insulation layer, resulting in limited heat dissipation efficiency. This causes heat to accumulate at the reflector and LED module, accelerating the aging of the LED module and reflector and hindering the lifespan of the sea sweeping lights.

[0005] Therefore, this application provides a high-power LED sea sweeping light focusing projection device to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a focusing projection device for a high-power LED sea sweeping light.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a focusing projection device for a high-power LED sea-sweeping light, comprising a sea-sweeping light body, and further comprising:

[0008] A heat dissipation assembly is placed inside the body of the sea sweeping lamp. The heat dissipation assembly includes a reflector disposed inside the body of the sea sweeping lamp, and heat dissipation fins are disposed outside the reflector. The heat dissipation fins are arranged in an array on the reflector.

[0009] A fixing component is placed on top of the heat dissipation component and used to fix the heat sink. The fixing component includes a fixing plate connected inside the body of the sea sweeper lamp near the heat sink. An insulating connecting plate is connected between the fixing plate and the heat sink. The heat sink is connected to the fixing plate through the insulating connecting plate.

[0010] Furthermore, a convex lens is provided inside the sea-sweeping lamp body on the side near the reflector.

[0011] The advantages of adopting the above-mentioned further solutions are: ensuring stable and concentrated light and increasing the projection distance.

[0012] Furthermore, a heat insulation plate is provided between the convex lens and the heat sink.

[0013] The beneficial effects of adopting the above-mentioned further solution are: preventing heat from the reflector from being conducted to the interior of the convex lens, avoiding thermal expansion of the convex lens, and ensuring the stability of the convex lens during use.

[0014] Furthermore, a sealing cap is connected to one end of the sea-sweeping lamp body, and a sealing plate is connected to the side of the sealing cap near the convex lens.

[0015] The beneficial effects of adopting the above-mentioned further solution are: when the sealing cover is connected to the body of the sea sweeping lamp, the sealing plate is inserted into the interior of the body of the sea sweeping lamp, so as to fill the gap between the sealing cover and the body of the sea sweeping lamp, reduce the impact of sea wind on the convex lens, and help improve the service life of the convex lens.

[0016] Furthermore, a transparent partition is connected to the inner side of the sealing cover.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it prevents the sea breeze from accelerating the wear of the convex lens, which is conducive to further improving the service life of the convex lens.

[0018] Furthermore, a heat dissipation hole is provided on one end of the sea sweeping lamp body near the heat sink, and the heat dissipation hole is distributed in a ring array on the sea sweeping lamp body.

[0019] The beneficial effect of adopting the above-mentioned further solution is that it enables the heat sink to fully exchange heat inside the body of the sea sweeper, ensuring the heat dissipation effect of the heat sink.

[0020] Furthermore, an insulating coating is provided at one end of the reflector.

[0021] The beneficial effect of adopting the above-mentioned further solution is to avoid direct contact between the reflector and the metal shell of the sea sweeping lamp body, thereby preventing short circuit damage to the sea sweeping lamp body.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. By setting up a heat dissipation component, the heat sink is tightly attached to the outside of the reflector. The heat generated by the reflector is transferred to the heat sink. The heat sink is installed on the reflector in an array layout, which expands the overall heat dissipation area by utilizing its own structure. The gaps reserved between adjacent heat sinks allow external cold air to come into full contact with the surface of the heat sink, ensuring efficient heat exchange between the two. This solves the problem of heat accumulation at the reflector and LED module, which accelerates the aging of the LED module and reflector. It improves the heat dissipation efficiency of the heat sink, reduces the wear and tear of the core components caused by high temperature, and helps to extend the service life of the sea sweeping light body.

[0024] 2. By setting up a fixing component, the fixing plate is welded to the top and bottom of the inner side of the sea sweeping lamp body, and threaded posts are welded on the fixing plate to securely install the insulating connecting plate between the fixing plate and the heat sink. Through this connection method, the heat sink can be reliably fixed inside the sea sweeping lamp body. The secure installation of the heat sink can ensure that it always maintains a stable fit with the reflector, thereby maintaining good heat dissipation efficiency. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1-6 As shown, this utility model provides a technical solution: a focusing projection device for a high-power LED sea sweeping light, including a sea sweeping light body 1, and further comprising:

[0037] like Figures 1-3 As shown, the heat dissipation component 2 is placed inside the body 1 of the sea sweeping lamp. The heat dissipation component 2 includes a reflector 21 disposed inside the body 1 of the sea sweeping lamp, and heat dissipation fins 22 disposed outside the reflector 21. The heat dissipation fins 22 are arranged in an array on the reflector 21.

[0038] like Figures 1-4 As shown, the fixing component 3 is placed on top of the heat dissipation component 2 and is used to fix the heat sink 22. The fixing component 3 includes a fixing plate 31 connected inside the body 1 of the sea sweeper lamp near the heat sink 22. An insulating connecting plate 32 connects the fixing plate 31 and the heat sink 22. The heat sink 22 is connected to the fixing plate 31 through the insulating connecting plate 32. By attaching the heat sink 22 to the outside of the reflector 21, the heat on the reflector 21 can be conducted to the heat sink 22, increasing the heat dissipation area of ​​the heat sink 22. At the same time, the heat sink 22 is arrayed on the reflector 21, and gaps are left between adjacent heat sinks 22 to facilitate the full contact of external cold air with the heat sink 22. The heat exchange between the heat sink 22 and the cool air is ensured, thus solving the problem of heat accumulation at the reflector 21 and LED module, which accelerates the aging of the LED module and reflector 21. This improves the heat dissipation effect of the heat sink 22 and extends the service life of the sweeping light body 1. The fixing plate 31 is welded to the top and bottom of the inner side of the sweeping light body 1, and threaded posts are welded on the fixing plate 31 to facilitate the use of nuts and washers to fix the insulating connecting plate 32 between the fixing plate 31 and the heat sink 22. This fixes the heat sink 22 inside the sweeping light body 1, ensuring that the heat sink 22 can maintain a stable fit with the reflector 21 and maintain heat dissipation efficiency.

[0039] Furthermore, such as Figures 2-3 As shown, a convex lens 23 is provided inside the body 1 of the sea sweeping lamp, near the reflector 21. By installing the convex lens 23 inside the body 1 of the sea sweeping lamp, the convex lens 23 further converges and shapes the light beam through the principle of refraction, ensuring that the light is stable and concentrated, and increasing the projection distance.

[0040] Furthermore, such as Figures 2-3 As shown, a heat insulation plate 24 is provided between the convex lens 23 and the heat sink 22. The heat insulation plate 24 is installed between the convex lens 23 and the reflector 21. The convex lens 23 is made of a high heat-resistant material to prevent heat from the reflector 21 from being conducted to the interior of the convex lens 23, avoid the convex lens 23 from thermal expansion, and ensure the stability of the convex lens 23 during use.

[0041] Furthermore, such as Figure 5 As shown, a sealing cover 25 is connected to one end of the sea sweeping lamp body 1. A sealing plate 26 is connected to the side of the sealing cover 25 near the convex lens 23. By opening threaded grooves on the sealing cover 25, the heat insulation plate 24, the convex lens 23, and the reflector 21, it is easy to use bolts to fix them inside the sea sweeping lamp body 1, ensuring the connection is firm. At the same time, the sealing plate 26 is adhered to one side of the sealing cover 25. When the sealing cover 25 is connected to the sea sweeping lamp body 1, the sealing plate 26 is inserted into the interior of the sea sweeping lamp body 1, filling the gap between the sealing cover 25 and the sea sweeping lamp body 1, reducing the impact of sea wind on the convex lens 23, and helping to improve the service life of the convex lens 23.

[0042] Furthermore, such as Figure 5 As shown, a transparent partition 27 is connected to the inner side of the sealing cover 25. The transparent partition 27 is installed on the inner side of the sealing cover 25 by using bolts to block the external sea wind from directly contacting the convex lens 23, preventing the sea wind from accelerating the wear of the convex lens 23, and helping to further improve the service life of the convex lens 23.

[0043] Furthermore, such as Figure 6 As shown, a heat dissipation hole 28 is provided on one end of the sea sweeping lamp body 1 near the heat sink 22. The heat dissipation holes 28 are arranged in a ring array on the sea sweeping lamp body 1. By opening the heat dissipation holes 28 arranged in a ring array, the external cold air can enter the interior of the sea sweeping lamp body 1 from different angles, so that the heat sink 22 can fully exchange heat inside the sea sweeping lamp body 1, and ensure the heat dissipation effect of the heat sink 22.

[0044] Furthermore, such as Figure 6 As shown, an insulating coating 29 is provided at one end of the reflector 21. By spraying the insulating coating 29 onto the side of the reflector 21 that contacts the body of the sea sweeping lamp 1, direct contact between the reflector 21 and the metal shell of the body of the sea sweeping lamp 1 is avoided, thus preventing the body of the sea sweeping lamp 1 from being short-circuited and damaged.

[0045] Working principle: such as Figures 1-6As shown, first, the insulating connecting plate 32 is installed on the heat sink 22. Then, the heat sink 22 is placed inside the body 1 of the sea sweeping lamp. Nuts and washers are then used to fix the heat sink 22 and the insulating connecting plate 32 inside the body 1 of the sea sweeping lamp using the fixing plate 31. Next, from the other side, the reflector 21, heat insulation plate 24, convex lens 23, and sealing cover 25 are placed inside the body 1 of the sea sweeping lamp and fixed with bolts, ensuring a tight fit between the reflector 21 and the heat sink 22. When the sealing cover 25 is connected to the body 1 of the sea sweeping lamp, the sealing plate 26 is inserted inside the body 1 of the sea sweeping lamp, filling the gap between the sealing cover 25 and the body 1 of the sea sweeping lamp, reducing the impact of sea winds on the convex lens 23. This causes an impact. At the same time, the transparent partition 27 blocks the external sea breeze from directly contacting the convex lens 23, activating the LED module inside the sea sweeping lamp body 1. The heat sink 22 and the convex lens 23 work together to concentrate the light, increasing the brightness and projection distance of the light. The external cold air enters the interior of the sea sweeping lamp body 1 through the heat dissipation hole 28. The heat sink 22 is arrayed on the reflector 21, and there are gaps between adjacent heat sinks 22 to facilitate the external cold air to fully contact the heat sink 22 and ensure heat exchange between the heat sink 22 and the cold air. At the same time, the heat insulation plate 24 blocks the heat of the reflector 21 to prevent the heat on the reflector 21 from being conducted to the interior of the convex lens 23 and avoid the convex lens 23 from expanding due to heat.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
