Although the above-mentioned patent can monitor the temperature of the LED lamp and perform double heat dissipation channel heat dissipation on the lamp, when the lamp holder and the heat dissipation fan stop running, the opening structure of the through hole cannot maintain the airtightness of the lamp, which causes the external dust and other pollutants to easily enter the inside of the lamp through the through hole, gradually adhere to the key components such as the lamp column, the heat sink and the internal circuit, and affect the light efficiency and heat dissipation performance. Therefore, the utility model provides a lighting lamp double circulation air duct heat sink to solve the problems in the above-mentioned background technology. UTILITY MODEL CONTENTS

[0010] According to the aforementioned dual-circulation air duct heat dissipation device for lighting lamps, the second filter assembly includes a second mounting plate disposed at the bottom of the housing and a second filter screen embedded inside the second mounting plate.

[0024] Reference Figures 1-5 This utility model discloses a dual-circulation air duct heat dissipation device for lighting, comprising a housing 1 made of a high thermal conductivity material. A lamp post 2 is fixed in the middle of the housing 1, forming an air duct between the lamp post 2 and the inner wall of the housing 1 for airflow heat dissipation. Multiple first heat sinks 4 are uniformly fixed on the inner wall of the housing 1. Multiple air inlets 3 are uniformly opened inside the housing 1 below the first heat sinks 4. A top plate 9 is installed on the top of the housing 1, and a fan 10 is fixed on the top of the top plate 9. A first filter assembly is provided between the top plate 9 and the housing 1. A second filter assembly is provided at the bottom of the housing 1 below the air inlets 3.

[0025] The lamp post 2 is installed in the middle of the bottom side of the housing 1. An air inlet 3 is provided on one side of the outer ring of the lamp post 2. A fan 10 is provided at the top of the housing 1. Air enters the interior of the housing 1 from the air inlet 3 and flows inside the air duct. The air contacts the lamp post 2, the first heat sink 4 and the inner wall of the housing 1. The airflow circulates to achieve efficient heat dissipation.

[0026] All air inlets 3 are inclined, with multiple air inlets 3 inclined in the same direction facing the first heat sink 4. Multiple second heat sinks 5 are evenly fixed on the outside of the lamp post 2 to enhance heat conduction efficiency. In addition, multiple air inlets 3 inclined in the same direction are inclined towards the second heat sink 5.

[0027] When air enters the housing 1 through the air inlet 3, the inclined air inlet 3 can optimize the airflow direction, so that the airflow can better contact the first heat sink 4 and the second heat sink 5, and improve the heat dissipation uniformity.

[0028] The first filter assembly includes a first mounting plate 7 located between the top plate 9 and the housing 1, and a first filter 8 embedded inside the first mounting plate 7. The second filter assembly includes a second mounting plate 11 located at the bottom of the housing 1, and a second filter 12 embedded inside the second mounting plate 11. A transparent plate 13 located below the lamp post 2 is also embedded inside the second mounting plate 11 to meet the light transmission requirements. The second filter 12 is located below the air inlet 3 and has a circular structure.

[0029] The first filter 8 is installed below the fan 10, and the second filter 12 is installed below the air inlet 3. The double-layer dustproof structure can prevent external dust from entering the interior of the housing 1, which helps to keep the interior of the housing 1 clean and tidy.

[0030] The top plate 9, the first mounting plate 7, and the second mounting plate 11 are all connected to the housing 1 by bolts, facilitating the removal of the first mounting plate 7 and the second mounting plate 11 for maintenance of the filter screen. Two Z-shaped mounting brackets 14 are symmetrically fixed to the outside of the housing 1 for easy fixed connection with the mounting surface.

[0031] The housing 1 is made of aluminum, which provides good thermal conductivity while achieving a lightweight structure. Furthermore, multiple grooves 6 are evenly distributed on the outer surface of the housing 1 to increase its natural heat dissipation area.

[0032] Working principle: The lamp post 2 is installed in the middle of the bottom side of the housing 1. An air inlet 3 is set on one side of the outer ring of the lamp post 2. A fan 10 is set on the top of the housing 1. Air enters the interior of the housing 1 from the air inlet 3 and flows inside the air duct. The air contacts the lamp post 2, the first heat sink 4 and the inner wall of the housing 1. The airflow circulates to achieve efficient heat dissipation.

[0033] When air enters the housing 1 through the air inlet 3, the inclined air inlet 3 can optimize the airflow direction, so that the airflow can better contact the first heat sink 4 and the second heat sink 5, and improve the heat dissipation uniformity.

[0034] The first filter 8 is installed below the fan 10, and the second filter 12 is installed below the air inlet 3. The double-layer dustproof structure can prevent external dust from entering the interior of the housing 1, which helps to keep the interior of the housing 1 clean and tidy.

[0035] By optimizing the air duct structure and airflow guidance design, air enters the housing from the inclined air inlet 3 on the outer ring of the lamp post 2. Driven by the fan 10, it forms a circulating airflow and fully contacts the lamp post, the first heat sink 4, and the wall of the housing 1, achieving efficient heat exchange. The inclined air inlet structure optimizes the airflow path, ensuring that the airflow evenly covers the first heat sink 4 and the second heat sink 5, avoiding localized overheating. At the same time, the double-layer dustproof design, consisting of the first filter 8 below the fan 10 and the second filter 12 below the air inlet 3, effectively blocks external dust from entering the housing 1, maintaining internal cleanliness, extending the lifespan of the lamp, and ensuring the long-term stable operation of the lighting fixture.

However, the present utility model 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 utility model.
