Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a high-temperature resistant LED lighting module. Background Technology

[0002] An LED lighting module is a fully functional lighting unit that integrates LED chips, driver power supply, heat dissipation substrate, optical lens (or lampshade), and mechanical structure.

[0003] Currently, LED lighting modules have a simple structure and lack efficient heat dissipation. Generally, only external cooling fans are installed. However, the cooling fans are directly fixed to the LED lighting module and draw in the surrounding air that has been heated by the LED lighting module. This reduces the heat dissipation efficiency of the LED lighting module and fails to dissipate heat from the inside of the LED lighting module, greatly reducing its high-temperature resistance and affecting its lifespan. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a high-temperature resistant LED lighting module, which can keep the two ends of the air extraction and exhaust away from the lamp housing through the convection tube, and can communicate with the inside of the lamp housing, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a high-temperature resistant LED lighting module, including a convection tube and a lamp housing. The middle of the convection tube is enlarged to form a flow guide section with an annular structure. The lamp housing is disposed in the flow guide section. An annular channel communicating with the convection tube is formed between the flow guide section and the outer ring of the lamp housing. Multiple annular heat dissipation fins are installed inside the annular channel. The inner ring of the heat dissipation fins is in contact with the outer ring surface of the lamp housing. Ventilation ports are provided on both sides of the lamp housing opposite to the convection tube. A cooling fan is installed in the opening at one end of the convection tube.

[0006] As a preferred technical solution, one end of the lamp housing is open, and a ring-shaped blocking part protrudes upward from the opening of the lamp housing. A lamp plate is provided in the opening at one end of the blocking part, and multiple LED lights are installed on the lamp plate. Multiple fixing posts are installed on the inner wall surface of the lamp housing away from the opening. The lamp plate is placed on the multiple fixing posts and is fixedly connected to the fixing posts and the lamp housing by bolts.

[0007] As a preferred technical solution, a lampshade is provided outside the opening of the lamp housing. One end of the lampshade opening protrudes to form a connecting part with an annular structure. The connecting part is inserted into the opening of the lamp housing and extends into the middle of the blocking part, and is threadedly connected to the blocking part and the opening of the lamp housing.

[0008] As a preferred technical solution, the lamp housing is circular in shape, with external threads on the outer ring surface and internal threads on the inner ring surface of the flow guide. The lamp housing is connected to the flow guide by the engagement of the external threads with the internal threads.

[0009] As a preferred technical solution, a wiring conduit communicating with the inner cavity of the lamp housing is installed at the other end of the lamp housing.

[0010] As a preferred technical solution, multiple mounting bases are installed on the convection pipe, and the mounting bases are provided with multiple mounting holes.

[0011] As a preferred technical solution, the lamp panel is connected to the convection pipe through a vent.

[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure. The convection tube allows the two ends of the air extraction and exhaust to be far away from the lamp housing. It can extract unheated air from a distance and also keep the exhaust gas away from the lamp housing to ensure heat dissipation. Furthermore, the gas generated by the cooling fan can be blown into the interior of the lamp housing through the vent and come into contact with the lamp plate, which can efficiently remove the internal heat. Some of the gas can also pass around the outer ring of the lamp housing and, combined with the heat dissipation fins, increase the contact area and enhance the heat dissipation effect. At the same time, the lamp housing is easy to install and disassemble, increasing its adaptability. Attached Figure Description

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a high-temperature resistant LED lighting module of this utility model includes a convection tube 1 and a lamp housing 3. The middle of the convection tube 1 is enlarged to form a flow guide 2 with an annular structure. The lamp housing 3 is disposed in the flow guide 2. An annular channel communicating with the convection tube 1 is formed between the flow guide 2 and the outer ring of the lamp housing 3. Multiple annular heat dissipation fins 12 are installed inside the annular channel. The inner ring of the heat dissipation fins 12 is in contact with the outer ring surface of the lamp housing 3. Ventilation ports 13 are provided on both sides of the lamp housing 3 and are opposite to the convection tube 1. A cooling fan 7 is installed in the opening at one end of the convection tube 1. The convection pipe has filters installed in the openings at both ends to effectively block dust and impurities.

[0020] In this embodiment, one end of the lamp housing 3 is open, and a blocking part 10 with an annular structure protrudes upward from the opening of the lamp housing 3. A lamp plate 9 is provided in the opening at one end of the blocking part 10. Multiple LED lights are installed on the lamp plate 9. Multiple fixing posts 8 are installed on the inner wall surface of the lamp housing 3 away from the opening. The lamp plate 9 is placed on the multiple fixing posts 8 and is fixedly connected to the fixing posts 8 and the lamp housing 3 by bolts.

[0021] In this embodiment, a lampshade 4 is provided outside the opening of the lamp housing 3. One end of the opening of the lampshade 4 protrudes to form a connecting part 11 with an annular structure. The connecting part 11 is inserted into the opening of the lamp housing 3 and extends into the middle of the blocking part 10, and is threadedly connected to the blocking part 10 and the opening of the lamp housing 3. The lampshade 4 is threadedly connected to the lamp housing 3 and the blocking part 10 via the connecting part 11, which facilitates installation and subsequent disassembly.

[0022] In this embodiment, the lamp housing 3 is circular in shape. The outer ring surface of the lamp housing 3 is provided with external threads, and the inner ring surface of the flow guide 2 is provided with internal threads. The lamp housing 3 is connected to the flow guide 2 by the engagement of the external threads with the internal threads. The lamp housing 3 is connected to the air guide 2 by threads, which facilitates disassembly and maintenance. The lamp plate 9 is installed by the fixing column 8, which can suspend the top of the lamp plate to ensure stability and heat conduction.

[0023] In this embodiment, a wiring conduit 5 communicating with the inner cavity of the lamp housing 3 is installed at the other end of the lamp housing 3, so that the wires on the lamp board can pass through the wiring conduit to extend to the outside and connect to the controller and power supply.

[0024] In this embodiment, multiple mounting bases 6 are installed on the convection pipe 1. The mounting bases 6 are provided with multiple fixing holes, and bolts can pass through the fixing holes to fix the convection pipe in the area where it needs to be installed.

[0025] In this embodiment, the lamp panel 9 is connected to the convection pipe 1 through the vent 13.

[0026] Airflow path for heat dissipation: After the cooling fan 7 starts, the driven air enters from one end of the convection pipe 1. The filters installed at both ends of the convection pipe can effectively block dust, insects and other pollutants from entering the module. When the clean airflow flows to the guide section 2 in the convection pipe 1, it splits into two paths: Internal heat dissipation path: A portion of the filtered clean airflow enters the interior of the lamp housing through the vents 13 on both sides of the lamp housing 3, and blows directly onto the surface of the lamp board 9, carrying away the heat generated by the LED chip during operation, thereby achieving direct cooling of the lamp board 9 and the inner cavity, while avoiding the accumulation of dust on the lamp board and LED chip.

[0027] External heat dissipation path: Another part of the airflow enters the annular channel formed by the guide section 2 and the outer ring of the lamp housing 3, and flows through multiple annular heat dissipation fins 12. The heat dissipation fins 12 are in close contact with the outer wall of the lamp housing 3, which increases the heat dissipation area. When the clean airflow passes through, it can efficiently carry away the heat conducted from the lamp housing 3 to the outer wall.

[0028] Heat exchange and exhaust: After absorbing heat inside the lamp housing 3, the internal airflow is discharged through convection and pressure difference. The external airflow exchanges heat with the heat dissipation fins 12 and the outer wall of the lamp housing 3 in the annular channel and is discharged along the other end of the convection pipe 1. The filter screen at the outlet also plays a protective role and prevents external foreign objects from entering in reverse through the exhaust port to a certain extent.

[0029] By extending the convection tube 1, the intake and exhaust ends of the cooling fan 7 are far away from the lamp housing 3, ensuring that the air drawn in is unheated air from a distance, and the hot air exhausted is also far away from the lamp housing, avoiding hot air backflow and significantly improving heat dissipation efficiency.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
