[0030] Example 1

[0031] like Figure 1-4 As shown, the present invention proposes a high-efficiency heat dissipation LED street light housing, which includes a housing 1, a top cover 2, a gasket 12, and a flow guiding assembly;

[0032] The top cover 2 is installed on the top of the housing 1 and is integrally arranged with the housing 1. The top of the top cover 2 is provided with a heat dissipation component that extends into the housing 1 and transfers heat from the inside of the housing 1 to the top of the top cover 2 for heat dissipation. The heat dissipation component is made of a high thermal conductivity material to ensure that heat is quickly conducted to the outside of the top cover 2 for heat dissipation, and to avoid overheating inside the housing 1.

[0033] The airflow guiding component is installed at the top of the top cover 2 and above the heat dissipation component. It is used to protect the heat dissipation component during use and prevent debris, such as airborne garbage and leaves, from contacting the heat dissipation component. At the same time, it guides the natural wind blowing towards the top cover 2, so that the natural wind moves along the top surface of the top cover 2, enhances the airflow effect, and allows the natural wind to contact the heat dissipation component and perform heat exchange, thereby improving the heat dissipation effect and ensuring the long-term stable operation of the LED light.

[0034] The gasket 12 is installed at the top of the top cover 2 and at the bottom edge of the heat dissipation assembly. It is used to seal the heat dissipation plate 8 and the top cover 2 during use to prevent rainwater from entering the inside of the top cover 2.

[0035] In this embodiment, by installing the heat dissipation component at the top of the top cover 2 and extending it into the housing 1, the heat dissipation component can more directly contact the heat source inside the housing 1 and transfer its heat to the outside of the top cover 2. This allows the heat dissipation component to exchange heat with the outside air, thus dissipating heat from the inside of the housing 1. At the same time, an air duct is formed between the air guide component and the top cover 2, allowing the air guide component to guide natural air along the outer surface of the top cover 2 and through the heat dissipation component, accelerating the heat dissipation of the heat dissipation component. This significantly improves the heat dissipation efficiency, ensuring that the LED street light can maintain stable performance under high load and extending its service life.

[0036] Example 2

[0037] like Figure 3-4 As shown, the present invention proposes a high-efficiency heat dissipation LED street light housing. The difference between this embodiment and the first embodiment is that the heat dissipation component includes a heat sink 8 and a heat sink 9.

[0038] The heat sink 8 is bolted to the top of the top cover 2;

[0039] The heat sink 9 has multiple fins, which are arranged at equal intervals at the bottom of the heat sink 8 and extend through the top cover 2 to the inside of the housing 1. They are used to contact the heat source inside the housing 1 during use, so that heat is transferred to the heat sink 8 and the heat dissipation effect inside the housing 1 is increased.

[0040] In an optional embodiment, the top of the top cover 2 is provided with a mounting groove 10, and the bottom of the mounting groove 10 is provided with a plurality of mounting holes 11. The heat sink 8 is fitted and connected in the mounting groove 10, and the heat sink 9 extends through the mounting holes 11 into the housing 1, so that the heat sink 8 drives the heat sink 9 through the mounting holes 11 and fits into the mounting groove 10, making it easier to disassemble and assemble the heat sink 8 and the heat sink 9.

[0041] In an optional embodiment, a slot 13 is provided at the bottom edge of the mounting groove 10 and below the edge of the heat sink 8. The gasket 12 is fitted into the slot 13 and connected to the heat sink 8 to limit the position of the slot 13 and prevent displacement that would cause a gap between the heat sink 8 and the top cover 2.

[0042] In an optional embodiment, a plurality of heat dissipation columns 4 are provided at the top of the heat dissipation plate 8. The plurality of heat dissipation columns 4 are arranged at equal intervals at the top of the heat dissipation plate 8 to increase the surface area of ​​the heat dissipation plate 8 during use, enhance the heat exchange efficiency with the outside air, and further optimize the heat dissipation effect.

[0043] In this embodiment, the heat sink 9 is fixed to the top of the top cover 2 by the heat sink plate 8, and the bottom end of the heat sink 9 is located inside the housing 1 and in contact with the heat source, so that the heat is transferred to the heat sink plate 8 through the heat sink 9. Then, the heat is accelerated to dissipate to the outside air due to the increased surface area of ​​the heat sink plate 8. At the same time, by setting multiple heat dissipation columns 4 at the top of the heat sink plate 8, the heat dissipation area is further increased, the heat exchange efficiency is improved, and the LED street light can still operate stably under high load, thus extending its service life.

[0044] Example 3

[0045] like Figure 2-3 As shown, this utility model proposes a high-efficiency heat dissipation LED street light housing. Compared with Embodiment 1, the difference in this embodiment is that the airflow guiding component includes an airflow guiding plate 3, a screw 5, and a connecting seat 6.

[0046] The airflow guide plate 3 is positioned above the heat sink 8;

[0047] There are multiple connecting seats 6, which are respectively installed on the top end of the top cover 2 and the bottom end of the guide plate 3. The connecting seats 6 on the top cover 2 and the guide plate 3 are arranged in a one-to-one correspondence.

[0048] Screw 5 is located at the top of the guide plate 3 and is connected to the two connecting seats 6.

[0049] In an optional embodiment, a connection hole 7 is provided at the top center of the guide plate 3, and the heat dissipation column 4 is inserted into the connection hole 7 to allow the end of the heat dissipation column 4 to contact the outside air during use, so as to avoid the guide plate 3 from obstructing the heat dissipation of the heat dissipation column 4.

[0050] In this embodiment, by installing the connecting seat 6 on the guide plate 3 and the top cover 2, and connecting the two connecting seats 6 with screws 5, the guide plate 3 is fixed above the heat sink 8, so that a stable airflow channel is formed between the guide plate 3 and the top cover 2, ensuring smooth airflow and further enhancing the heat dissipation effect.

[0051] Example 4

[0052] like Figure 1-2 As shown, this utility model proposes a high-efficiency heat dissipation LED street light housing. Compared with the first embodiment, the difference is that the size of the guide plate 3 is larger than that of the heat dissipation plate 8, which is used to protect the heat dissipation column 4 and prevent airborne garbage from connecting with the heat dissipation column 4, thus reducing the heat dissipation effect of the heat dissipation plate 8.

[0053] In an optional embodiment, the top projection shapes of both the top cover 2 and the deflector 3 are arc-shaped to guide natural wind and prevent rainwater from accumulating on the heat sink 8.

[0054] In this invention, the heat sink 9 is fixed to the top of the top cover 2 by the heat sink plate 8, and the bottom end of the heat sink 9 extends to the inside of the housing 1 to contact the heat source, so that heat is transferred to the heat sink plate 8 through the heat sink 9. Then, due to the increased surface area of ​​the heat sink plate 8, the heat is dissipated to the outside air more quickly. At the same time, by setting multiple heat dissipation columns 4 at the top of the heat sink plate 8, the heat dissipation area is further increased and the heat exchange efficiency is improved. The guide plate 3 is installed above the heat sink plate 8 by the cooperation of the screw 5 and the connecting seat 6, so that the guide plate 3 and the top cover 2 form a stable guide channel, so that the natural wind moves along the outer surface of the top cover 2 and through the heat sink plate 8 and the heat dissipation columns 4, accelerating the heat dissipation of the heat dissipation columns 4 and the heat sink plate 8, thereby significantly improving the heat dissipation efficiency, ensuring that the LED street light can maintain stable performance under high load and extending its service life.

[0055] 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 thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
