Description

Technical Field

[0001] This utility model relates to the field of navigation light technology, and in particular to a high-range navigation light. Background Technology

[0002] High-range light beacon lights are widely used in waterways, ports, and along coastlines to provide long-distance marking and guidance for ship navigation and maritime operations. They need to have stable high-power luminous capability to achieve the expected range. To meet the high-range requirements, the light beacon lights typically need to continuously output high power, which generates a lot of heat under high-power operation. The heat dissipation structure of existing high-range lamp posts mostly adopts a fixed heat dissipation base. The heat dissipation area of ​​the heat dissipation base is fixed and cannot be adjusted, which cannot flexibly adapt to the heat dissipation needs according to the actual heat generation of the lamp group. Utility Model Content

[0003] To address the technical problem that the heat dissipation area of ​​the heat dissipation base of high-range beacon lights is fixed and cannot be adjusted in the existing technology, this utility model provides a high-range navigation light.

[0004] The technical solution adopted in this utility model is: a high-range navigation light, comprising: a heat dissipation base, a heat dissipation column, a heat dissipation plate, a light assembly, and a convex lens; The heat dissipation column is disposed on the top of the heat dissipation base; the lamp assembly is arranged around the outer surface of the heat dissipation column; the heat dissipation plate is disposed on the top of the heat dissipation column; the convex lens is disposed between the heat dissipation base and the heat dissipation plate; there is a gap between the convex lens and the outer wall of the heat dissipation column; the convex lens is used to converge the light emitted by the lamp assembly. At least one heat dissipation area expansion component is provided on the outer wall of the heat dissipation base, and the heat dissipation area expansion component is detachably connected to the outer wall of the heat dissipation base.

[0005] Preferably, the heat dissipation area expansion component has multiple vertical plates arranged at equal intervals, and adjacent vertical plates and the heat dissipation area expansion component enclose each other to form a first airflow cavity; the first airflow cavity is used to allow external airflow to pass through.

[0006] Preferably, the outer wall of the metal heat sink base is provided with multiple blocks, and an installation area is formed between adjacent blocks. The installation area is used to accommodate the heat dissipation area expansion component.

[0007] Preferably, an antenna is provided at the top of the heat dissipation column, and a central hole is provided at the top of the heat dissipation plate, with the central hole located above the antenna.

[0008] Preferably, the top of the heat sink is provided with an antenna cover, which is used to block the central hole.

[0009] Preferably, the heat sink has multiple horizontal plates evenly spaced, and adjacent horizontal plates and the heat sink together form a second airflow cavity; the second airflow cavity is used for external airflow to pass through. Preferably, a heat-conducting component is provided between the connection surfaces of the lamp assembly and the heat dissipation column, and the heat-conducting component is used to transfer the heat generated by the lamp assembly to the heat dissipation column.

[0010] Preferably, the radome is made of plastic.

[0011] The beneficial effects of this utility model are as follows: the heat generated by the lamp assembly during operation is first quickly transferred to the heat dissipation column through the heat-conducting component. The heat dissipation column conducts part of the heat to the top heat dissipation plate and the other part to the bottom heat dissipation base. If the lamp assembly generates less heat, the heat dissipation base itself can meet the heat dissipation requirements. If the heat generation increases, a heat dissipation area expansion component can be installed in the installation area of ​​the heat dissipation base. The heat dissipation area expansion component increases the heat dissipation capacity by increasing the heat dissipation area. The entire heat dissipation process can be flexibly adapted to different heat generation conditions of the lamp assembly by adding or removing the heat dissipation area expansion component, thus solving the problem that the heat dissipation area of ​​the traditional fixed heat dissipation base is not adjustable.

[0018] An embodiment provides a high-range navigation light, such as Figure 1 and Figure 2 As shown, it includes: a heat dissipation base 1, a heat dissipation column 2, a heat dissipation plate 3, a lamp assembly 4, and a convex lens 5.

[0019] like Figure 2 As shown, the heat dissipation column 2 is located on top of the heat dissipation base 1. Specifically, the heat dissipation column 2 and the heat dissipation base 1 are made of metal, such as aluminum alloy. The tops of the heat dissipation column 2 and the heat dissipation base 1 can be fixed by welding. Since both the heat dissipation base 1 and the heat dissipation column 2 need to bear the function of heat conduction, welding can achieve a gapless connection between the two, reduce thermal resistance, ensure that the heat on the heat dissipation column 2 can be efficiently transferred to the heat dissipation base 1, and at the same time ensure structural stability and prevent the light post from separating due to vibration in the outdoor environment.

[0020] like Figure 2 As shown, the lamp assembly 4 is arranged around the outer surface of the heat dissipation column 2. In one possible embodiment, a heat-conducting element (not shown) is provided between the connection surfaces of the lamp assembly 4 and the heat dissipation column 2, the heat-conducting element (not shown) being used to transfer the heat generated by the lamp assembly 4 to the heat dissipation column 2.

[0021] Specifically, the lamp assembly 4 is ring-shaped on the outer surface of the heat dissipation column 2 and can be connected by bolts and thermally conductive adhesive. The back of the lamp assembly 4 has a pre-cut arc-shaped mounting plate that matches the outer circle of the heat dissipation column 2. The mounting plate has bolt holes and corresponding threaded holes on the outer wall of the heat dissipation column 2. The mounting plate of the lamp assembly 4 is tightly fixed to the outer wall of the heat dissipation column 2 by bolts. At the same time, thermally conductive adhesive is applied between the mounting plate and the outer wall of the heat dissipation column 2 to enhance the sealing and further reduce the thermal resistance. With the help of the thermally conductive component (such as a copper thermally conductive sheet, which is fixed between the two by screws) between the lamp assembly 4 and the heat dissipation column 2, the heat of the lamp assembly 4 can be quickly transferred to the heat dissipation column 2.

[0022] The heat sink 3 is disposed on the top of the heat sink column 2, and the convex lens 5 is disposed between the heat sink base 1 and the heat sink 3; there is a gap between the convex lens 5 and the outer wall of the heat sink column 2, and the convex lens 5 is used to focus the light emitted by the lamp group 4.

[0023] For example, the top of the heat sink 3 and the heat sink column 2 can be connected by a flange and locating pins for auxiliary connection; for example, the top of the heat sink column 2 has an integrally formed annular flange with bolt holes, and the center of the heat sink 3 has a corresponding mounting hole, and the heat sink 3 is fastened to the flange by bolts; at the same time, 2-3 locating pins are set between the flange and the heat sink 3, one end of the locating pin is embedded in the pin hole of the flange of the heat sink column 2, and the other end is inserted into the corresponding pin hole of the heat sink 3, to ensure that the heat sink 3 will not be offset during installation and can remain coaxial with the heat sink column 2, so as to avoid affecting the light focusing effect of the convex lens 5.

[0024] like Figure 1 As shown, at least one heat dissipation area expansion component 6 is provided on the outer side wall of the heat dissipation base 1, and the heat dissipation area expansion component 6 is detachably connected to the outer side wall of the heat dissipation base 1.

[0025] In one possible implementation, such as Figure 1 and Figure 3 As shown, a plurality of blocks 9 are provided on the outer side wall of the metal heat sink base 1, and an installation area 10 is formed between adjacent blocks 9. The installation area 10 is used to accommodate the heat dissipation area expansion component 6.

[0026] For example, the heat dissipation area expansion component 6 and the outer wall of the heat dissipation base 1 can be fixed by snap-fit ​​and screws. The stop block 9 on the outer wall of the heat dissipation base 1 is made of metal and is fixed to the outer wall of the heat dissipation base 1 by welding. The installation area 10 formed by adjacent stop blocks 9 has an n-shaped cross section. The installation area 10 and the heat dissipation area expansion component 6 are fitted with a clearance. During installation, the heat dissipation area expansion component 6 is inserted into the installation area 10 to achieve initial positioning. Then, two screws are screwed into the heat dissipation area expansion component 6, with the ends of the screws screwed into the outer wall of the heat dissipation base 1 to further fix the expansion component and prevent it from loosening in windy and rainy environments. During disassembly, simply unscrew the screws and pull out the heat dissipation area expansion component 6. In this embodiment, the heat dissipation area expansion component 6 can be a heat dissipation area expansion plate.

[0027] In one possible implementation, such as Figure 1 and Figure 3 As shown, multiple vertical plates 7 are evenly spaced on the heat dissipation area expansion component 6, and adjacent vertical plates 7 and the heat dissipation area expansion component 6 enclose each other to form a first airflow cavity 8; the first airflow cavity 8 is used to allow external airflow to pass through.

[0028] For example, the heat dissipation area expansion component 6 is a thin metal plate (such as an aluminum alloy plate). The horizontal plate 14 and the heat dissipation plate 3 are integrally formed by stamping. The vertical plate 7 is perpendicular to the surface of the heat dissipation area expansion component 6. The distance between adjacent vertical plates 7 is 20-30mm. The height of the vertical plate 7 is the same as the height of the expansion component. The first airflow cavity 8 formed by the two is rectangular in cross-section. The first airflow cavity 8 is a through structure, which allows external airflow (such as natural wind) to flow smoothly through it. The airflow carries away the heat on the surface of the heat dissipation area expansion component 6, which significantly improves the heat dissipation efficiency. For example, when the lamp group 4 generates more heat during high-power operation, after installing the heat dissipation area expansion component 6, the first airflow cavity 8 can accelerate the heat dissipation through air convection and avoid heat accumulation.

[0029] In one possible implementation, such as Figure 4 As shown, multiple horizontal plates 14 are evenly spaced on the heat sink 3. Adjacent horizontal plates 14 and the heat sink 3 enclose each other to form a second airflow cavity 15. The second airflow cavity 15 is used for the flow of external air. The specific connection relationship between the horizontal plates 14 and the heat sink 3 is similar and will not be described again here. Adjacent horizontal plates 14 and the surface of the heat sink 3 enclose each other to form the second airflow cavity 15. The second airflow cavity 15 has a similar function to the first airflow cavity 8, both being used for the flow of external air to carry away the heat on the heat sink 3 through air convection. Since the heat sink 3 is connected to the top of the heat sink column 2, it will receive the heat conducted by the heat sink column 2. The second airflow cavity 15 can assist the heat sink 3 in quickly dissipating heat, further improving the heat dissipation efficiency of the entire device.

[0030] In one possible implementation, such as Figure 2 and Figure 4As shown, an antenna 11 is provided on the top of the heat dissipation column 2, and a central hole 12 is provided on the top of the heat dissipation plate 3, with the central hole 12 located above the antenna 11.

[0031] For example, a mounting hole with an internal thread is opened at the center of the top of the heat sink 2, and an external thread connector is provided at the bottom of the antenna 11. The antenna 11 connector is screwed into the mounting hole of the heat sink 2. After screwing, waterproof sealant is applied at the connection between the connector and the heat sink 2 to prevent rainwater from seeping into the interior of the heat sink 2. At the same time, the coaxiality of the antenna 11 and the heat sink 2 is ensured to ensure that the signal transmission direction is not obstructed.

[0032] In one possible implementation, such as Figure 2 As shown, the top of the heat sink 3 is provided with an antenna cover 13, which is used to seal the central hole 12. The antenna cover 13 is made of plastic.

[0033] For example, the top of the heat sink 3 has an annular threaded groove around the central hole 12. The radome 13 is made of plastic, and its bottom is integrally formed with an annular connecting part with external threads. A rubber sealing ring is fitted on the outside of the connecting part. During installation, the connecting part of the radome 13 is screwed into the threaded groove of the heat sink 3. The rubber sealing ring is squeezed between the radome 13 and the heat sink 3, which not only achieves sealing and waterproofing but also enhances the connection stability and prevents the radome 13 from falling off due to wind and vibration. The radome 13 is made of plastic (plastic material has the characteristics of being lightweight, having good insulation, and being weather-resistant, and can adapt to harsh environments such as humid seas and salt spray), which can protect the antenna 11 from external wind, rain, and impurities without affecting the signal transmission performance of the antenna 11.

[0034] In summary, the heat generated by the lamp assembly 4 during operation is first rapidly transferred to the heat dissipation column 2 through the heat-conducting component. The heat dissipation column 2 conducts part of the heat to the top heat dissipation plate 3 and the other part to the bottom heat dissipation base 1. The second airflow cavity 15 on the heat dissipation plate 3 allows external airflow to pass through, and the airflow carries away the heat on the surface of the heat dissipation plate 3. If the lamp assembly 4 generates less heat, the heat dissipation base 1 itself can meet the heat dissipation requirements. If the heat generation increases, a heat dissipation area expansion component 6 can be installed in the installation area 10 of the heat dissipation base 1. The expansion component increases the heat dissipation area to improve the heat dissipation capacity. At the same time, its first airflow cavity 8 allows airflow to pass through, further accelerating heat dissipation. The entire heat dissipation process can be flexibly adapted to different heat generation conditions of the lamp assembly 4 by adding or removing the heat dissipation area expansion component 6, solving the problem of the non-adjustable heat dissipation area of ​​the traditional fixed heat dissipation base 1.

[0035] The light assembly 4 is arranged around the outer surface of the heat dissipation column 2. After emitting light, the light radiates in all directions. The convex lens 5 located between the heat dissipation base 1 and the heat dissipation plate 3 will converge the scattered light emitted by the light assembly 4, so that the light is concentrated and propagated to a long distance, thereby realizing the high-range marking and guidance function and meeting the identification needs of ships when sailing over long distances.

[0036] The antenna 11 at the top of the heat dissipation column 2 passes through the central hole 12 of the heat dissipation plate 3 and is used to receive or send signals such as remote control and status monitoring. The plastic antenna cover 13 at the top of the heat dissipation plate 3 seals the central hole 12 to prevent rainwater, dust and other substances from entering the device and damaging the components. On the other hand, it protects the antenna 11 from external environmental corrosion and ensures stable signal transmission.

[0037] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
