Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a convection-cooled LED lamp housing structure. Background Technology

[0002] In the modern lighting field, LED lights are widely used in many scenarios such as indoor and outdoor lighting, traffic lights, and displays due to their advantages such as energy saving, long life and fast response speed. However, as the power of LED lights continues to increase, they will generate a lot of heat during operation. If the heat cannot be dissipated in time, the temperature of the LED chip will rise, which will affect its luminous efficiency and lifespan, and may even damage the LED light.

[0003] Currently, most common LED light heat dissipation methods rely on passive heat dissipation structures such as heat sinks, which increase the heat dissipation area to achieve natural convection and radiation of heat. However, this method has limited effectiveness in heat dissipation of high-power LED lights and is difficult to meet actual needs. Although some products have introduced forced convection cooling fans, their structural design often suffers from problems such as unreasonable airflow organization, inconvenient installation and disassembly, and insufficient protection. The low heat conduction efficiency of the fan and the lamp board results in heat not being able to be dissipated quickly, and the outer shell structure cannot effectively guide airflow to form an efficient convection channel, which greatly reduces the heat dissipation effect. At the same time, the lack of reasonable protection design allows dust and foreign objects to easily enter and affect the normal operation of the fan and the lamp board.

[0004] To address this, a convection-cooled LED lamp housing structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a convection-based LED lamp housing structure, which can solve the problem that existing LED lamp heat dissipation methods mostly rely on passive heat dissipation structures such as heat sinks. By increasing the heat dissipation area, natural convection and radiation of heat can be achieved. However, this method has limited effectiveness in heat dissipation of high-power LED lamps and is difficult to meet actual needs. Although some products have introduced forced convection cooling fans, there are often problems in the structural design such as unreasonable airflow organization, inconvenient installation and disassembly, and insufficient protection performance. The low heat conduction efficiency of the fan and lamp board results in heat not being able to be quickly dissipated. The housing structure cannot effectively guide airflow to form an efficient convection channel, which greatly reduces the heat dissipation effect. At the same time, the lack of reasonable protection design makes it easy for dust and foreign objects to enter and affect the normal operation of the fan and lamp board.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convection heat dissipation LED lamp housing structure, including a lamp housing, a lamp board disposed inside the lamp housing, a mounting assembly disposed above the lamp board, the mounting assembly including a mounting ring, and a forced convection assembly disposed inside the mounting ring;

[0007] The forced convection component includes a carrier plate, and multiple miniature axial flow fans are fixedly connected inside the carrier plate. A heat dissipation grease plate is provided at the bottom of the carrier plate, and the bottom of the heat dissipation grease plate is tightly attached to the top of the lamp plate. A connecting rod is fixedly connected to the surface of the heat dissipation grease plate, and the movement of the connecting rod near the carrier plate is fixedly connected to the carrier plate.

[0008] Preferably, a connecting ring is fixedly connected to the bottom of the mounting ring, and a connecting groove is provided on the top of the lamp housing to cooperate with the connecting ring.

[0009] Preferably, the lamp housing has insert rods extending through both sides, and the connecting ring has insertion holes on its surface that are used in conjunction with the insert rods.

[0010] Preferably, a circular block is fixedly connected to one end of the insertion rod located on the outside of the lamp housing, and a fastening spring is sleeved on the surface of the insertion rod, with both ends of the fastening spring being fixedly connected to the circular block and the lamp housing, respectively.

[0011] Preferably, an alignment block is fixedly connected to the surface of the connecting ring, and an alignment groove is provided inside the connecting groove, which is used in conjunction with the alignment block.

[0012] Preferably, a guide ring is fixedly connected inside the lamp housing and is located below the lamp plate. The guide ring is tapered and its inclined surface is opposite to that of the lamp plate.

[0013] Preferably, an external threaded ring is fixedly connected to the top of the mounting ring, an mounting cylinder is threadedly connected to the surface of the external threaded ring, and a filter screen is fixedly connected to the inside of the mounting cylinder.

[0014] Preferably, a lampshade is fixedly connected to the bottom of the lamp housing, and the surface of the lampshade has multiple heat outlet holes with the interior of the heat outlet holes being mesh-like.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up a forced convection component, multiple micro axial flow fans can actively blow air to form forced convection. Compared with natural convection heat dissipation, this greatly improves the air flow speed. The fast-flowing air can quickly remove the heat conducted by the heat dissipation grease plate, effectively reduce the temperature of the lamp board, thereby improving the luminous efficiency and service life of the lamp board and reducing the light decay caused by high temperature.

[0017] 2. This application, by setting up an installation component, through the cooperation of the connecting ring and the connecting groove, enables the installation component to be quickly and accurately installed on the top of the lamp housing. When disassembling, simply pull the circular block to overcome the elastic force of the fastening spring, and the installation component can be easily separated, which greatly improves the efficiency of installation and maintenance, and facilitates the later inspection and replacement of internal components such as the forced convection component and the light panel.

[0025] 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.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A convection-cooled LED lamp housing structure includes a lamp housing 1, a lamp plate 2 is disposed inside the lamp housing 1, a mounting assembly 3 is disposed above the lamp plate 2, the mounting assembly 3 includes a mounting ring 301, and a forced convection assembly 4 is disposed inside the mounting ring 301.

[0028] The forced convection component 4 includes a carrier plate 401. A miniature axial flow fan 402 is fixedly connected inside the carrier plate 401, and the number of miniature axial flow fans 402 is set to multiple. A heat dissipation grease plate 403 is provided at the bottom of the carrier plate 401. The bottom of the heat dissipation grease plate 403 is tightly attached to the top of the lamp plate 2. A connecting rod 404 is fixedly connected to the surface of the heat dissipation grease plate 403, and the movement of the connecting rod 404 near the carrier plate 401 is fixedly connected to the carrier plate 401.

[0029] In this embodiment: By setting a forced convection component 4, the carrier plate 401 serves as the core carrier of the forced convection component 4, and multiple miniature axial flow fans 402 are fixed inside. This provides installation space and support structure for the miniature axial flow fans 402, ensuring that the airflow can evenly cover the heat dissipation area. The miniature axial flow fans 402 accelerate airflow through blade rotation. The high-speed airflow can carry away the heat transferred by the thermal grease plate 403, significantly improving heat dissipation efficiency compared to natural convection, quickly reducing the temperature of the lamp board 2, and ensuring the stable operation of the lamp board 2. 03. With its high thermal conductivity silicone grease material, it fits tightly against the top of the lamp board 2, which can quickly absorb the heat generated when the lamp board 2 is working and conduct it evenly to the carrier plate 401 area. Its close contact with the lamp board 2 effectively eliminates the thermal resistance caused by air gaps and significantly enhances the heat conduction efficiency. The connecting rod 404 is used to fix the heat dissipation silicone grease plate 403 to the carrier plate 401, ensuring that the two always keep in close contact with the light-emitting lamp board 2, preventing loosening of contact due to vibration and other factors during use, thereby ensuring the stability and efficiency of the heat conduction path.

[0030] Specifically, such as Figure 5 As shown, a connecting ring 302 is fixedly connected to the bottom of the mounting ring 301, and a connecting groove 303 that works with the connecting ring 302 is provided on the top of the lamp housing 1.

[0031] Specifically, such as Figure 5 As shown, insert rods 304 penetrate both sides of the surface of the lamp housing 1, and the surface of the connecting ring 302 is provided with insertion holes 305, which are used in conjunction with the insert rods 304.

[0032] Specifically, such as Figure 5 As shown, a circular block 306 is fixedly connected to one end of the insertion rod 304 located on the outside of the lamp housing 1. A fastening spring 307 is sleeved on the surface of the insertion rod 304, and the two ends of the fastening spring 307 are fixedly connected to the circular block 306 and the lamp housing 1 respectively.

[0033] Specifically, such as Figure 6 As shown, a positioning block 5 is fixedly connected to the surface of the connecting ring 302, and a positioning groove 6 is provided inside the connecting groove 303. The positioning groove 6 is used in conjunction with the positioning block 5.

[0034] In this embodiment: Through the above settings, the connecting ring 302 can cooperate with the connecting groove 303 to provide initial axial positioning for the mounting ring 301 and the lamp housing 1. During installation, the connecting ring 302 can be quickly embedded into the connecting groove 303, so that the mounting ring 301 can be accurately placed at the corresponding position on the top of the lamp housing 1, avoiding installation offset and laying the foundation for subsequent fastening operations. The insertion rod 304 can be used in conjunction with the insertion hole 305 on the surface of the connecting ring 302. After the connecting ring 302 and the connecting groove 303 are initially positioned, the insertion rod 304 can be inserted into the insertion hole 305, which can effectively limit the circumferential rotation of the mounting ring 301 relative to the lamp housing 1, ensuring that the mounting ring 301 will not rotate due to external force or vibration during use, ensuring that the relative position of the forced convection assembly 4 and the light-emitting lamp plate 2 is fixed, and ensuring that the forced convection assembly 4 can operate stably. The circular block 306 facilitates user operation by allowing easy insertion and removal of the insertion rod 304. The tension generated by the elastic deformation of the fastening spring 307 ensures that the insertion rod 304 remains inserted into the insertion hole 305. Even under equipment vibration or external impact, it prevents the insertion rod 304 from slipping out, ensuring the tightness and reliability of the connection between the mounting ring 301 and the lamp housing 1. It also facilitates quick assembly and disassembly, improving maintenance efficiency. The alignment block 5 on the surface of the connecting ring 302 matches the shape of the alignment groove 6 inside the connecting groove 303. During installation, the alignment block 5 can only be inserted into the alignment groove 6 in a specific direction, providing precise guidance. This allows the connecting ring 302 to engage with the connecting groove 303 more quickly and accurately, further improving the accuracy and efficiency of installation and ensuring the tightness and stability of the connection between the mounting component 3 and the lamp housing 1.

[0035] Specifically, such as Figure 4 As shown, a guide ring 7 is fixedly connected inside the lamp housing 1 and is located below the lamp plate 2. The guide ring 7 is tapered and its inclined surface is opposite to that of the lamp plate 2.

[0036] Specifically, such as Figure 2 As shown, an external threaded ring 8 is fixedly connected to the top of the mounting ring 301, and a mounting cylinder 9 is threadedly connected to the surface of the external threaded ring 8. A filter screen 10 is fixedly connected inside the mounting cylinder 9.

[0037] In this embodiment: By setting the conical guide ring 7 as described above, when the micro axial flow fan 402 blows air downwards, the inclined surface of the guide ring 7 can guide the airflow evenly to the edge of the lamp plate 2, forming an airflow pattern that diffuses from the center of the lamp plate 2 to the surrounding area. This avoids the local vortex caused by the airflow directly downwards in the traditional structure, so that the entire surface of the lamp plate 2 can be effectively cooled. By guiding the airflow, a larger area of ​​the lamp plate 2 can be covered, extending the contact time between the hot air and the lamp plate 2 and improving the heat transfer efficiency. The filter 10 inside the mounting cylinder 9 can effectively intercept dust particles in the air sucked in by the micro axial flow fan 402, and also ensure sufficient ventilation. The threaded connection between the external threaded ring 8 and the mounting cylinder 9 allows the mounting cylinder 9 to be quickly disassembled and replaced. When used in a dusty environment, the user can periodically remove the mounting cylinder 9 to clean or replace the filter 10, resulting in low maintenance costs and simple operation.

[0038] Specifically, such as Figure 2 As shown, a lampshade 11 is fixedly connected to the bottom of the lamp housing 1. The surface of the lampshade 11 has multiple heat outlet holes, and the interior of the heat outlet holes is set as a mesh.

[0039] In this embodiment: Through the above settings, the forced convection component 4 can discharge the heat generated by the lamp panel 2 through the heat outlet hole to the lamp housing 1. While ensuring ventilation and heat dissipation, it can effectively block foreign objects such as dust, insects, and debris from entering the lamp housing 1, thereby protecting the lamp panel 2 and the forced convection component 4 from pollution and damage, and improving the overall service life.

[0040] Working principle: First, align the connecting ring 302 at the bottom of the mounting ring 301 with the connecting groove 303 at the top of the lamp housing 1. Utilize the alignment block 5 on the surface of the connecting ring 302 to engage with the alignment groove 6 within the connecting groove 303 to quickly and accurately position the mounting assembly 3. Insert the insertion rod 304 into the insertion hole 305 of the connecting ring 302 from both sides of the lamp housing 1. The circular block 306 on the outer side of the insertion rod 304 facilitates force application, and the elasticity of the tightening spring 307 ensures the insertion rod 304 is securely inserted, preventing the mounting ring 301 from rotating or loosening. Then, thread the mounting cylinder 9 onto the external threaded ring 8 at the top of the mounting ring 301. The filter screen 10 inside the mounting cylinder 9 can... The lamp board 2 serves a dustproof function. After being powered on, the lamp board 2 begins to emit light and generate heat. The heat is quickly absorbed by the heat dissipation grease plate 403 that is in close contact with it. The micro axial flow fan 402 inside the cylinder carrier plate 401 starts, generating forced convection. The heat conducted from the heat dissipation grease plate 403 is transported downward through airflow. The conical guide ring 7 inside the lamp housing 1 guides the airflow, making the airflow evenly diffuse to the edge of the lamp board 2, enhancing the heat exchange efficiency. The hot air carrying heat will eventually be discharged outside the lamp housing 1 through the heat outlet holes on the surface of the lamp cover 11, completing the heat dissipation cycle and ensuring that the lamp board 2 operates stably at a suitable temperature.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
