Description

Technical Field

[0001] This utility model relates to a heat dissipation adjustment mechanism, and in particular to a heat dissipation adjustment mechanism for LED spotlights, belonging to the field of LED spotlight technology. Background Technology

[0002] In the prior art, such as the utility model application with application number 202120304281.5, a heat dissipation adjustment mechanism for LED spotlights is disclosed. Through the setting of a heat-conducting rod, the heat generated by the spotlight body is easily discharged to the turbine blades. When the cooling fan is activated, the airflow speed inside the lamp tube is accelerated, and the heat flows to the condenser tube. After being cooled by the condenser tube, the hot air is easily discharged from the inside of the lamp tube through the heat dissipation grid. The guide plate is set to facilitate the concentrated discharge of the cooled air, resulting in good heat dissipation and ventilation. When the air inside the lamp tube passes through the guide plate, it will... The guide plate rotates and moves the connecting block to squeeze the buffer component, which provides a certain buffering effect on the guide plate. When the heat dissipation grid moves, the snap-fit ​​block on one side gradually moves and separates from the snap-fit ​​groove. The embedded groove moves with the snap-fit ​​block, and then separates from the gravity ball when the embedded groove moves. When the snap-fit ​​block and the snap-fit ​​groove are completely separated, the heat dissipation grid can be disassembled, which facilitates rapid heat dissipation inside the lamp tube and timely inspection and maintenance. It has a good performance effect, and the large amount of heat generated by the spotlight body when it is illuminated can be easily dissipated, which facilitates better heat dissipation treatment of LED spotlights, improves the service life of LED spotlights, and makes them more practical.

[0004] The guide plate used in the heat dissipation adjustment mechanism of LED spotlights can only passively rotate slightly with the airflow, and the heat dissipation grid is fixed and cannot be adjusted. It is difficult to flexibly adjust the heat dissipation direction, which may cause the discharged heat to return to the air intake end due to airflow factors, resulting in slow heat dissipation and reduced heat dissipation efficiency.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes a heat dissipation adjustment mechanism for an LED spotlight, including a housing 1. The housing 1 is made of aluminum alloy with a thickness of 3-5mm to ensure strength and heat dissipation performance. A spotlight body 2 is installed at one end of the housing 1. A heat-conducting plate 3 is fixed on one side of the spotlight body 2. The heat-conducting plate 3 is made of copper alloy and is disc-shaped with good thermal conductivity. Through holes 15 are evenly opened on the outer side of the housing 1. A cooling fan 4 is installed inside the housing 1. A flow guiding mechanism 5 is provided on the housing 1. A rotating tube 6 is provided at the other end of the housing 1. A movable leaf 16 is evenly rotated inside the rotating tube 6. A limiting member 7 is provided between the movable leaf 16 and the rotating tube 6. An outer ring 8 is sleeved on the outer side of the rotating tube 6. A retaining ring 9 is sleeved at the end of the housing 1. A screw 10 is symmetrically rotated on the retaining ring 9, and the end of the screw 10 passes through and extends to the outside of the outer ring 8. A sliding hole 12 is opened at the connection between the outer ring 8 and the screw 10. A limiting ring 11 is threaded on the outer side of the screw 10.

[0030] Rotate the limiting ring 11 to move it to the right, and slide the outer ring 8 to the right. The outer ring 8 drives the rotating tube 6 to separate from the outer shell 1. Then rotate the outer ring 8 to drive the movable page 16 and the rotating tube 6 to rotate. While the outer ring 8 is rotating, the screw 10 on the retaining ring 9 slides along the inside of the sliding hole 12. After observing that the movable page 16 rotates with the rotating tube 6 to a suitable angle, reverse the limiting ring 11 to move it to the left. The limiting ring 11 pushes the outer ring 8 to move to the left, so that the rotating tube 6 is tightly connected to the outer shell 1, and the rotating tube 6 is fixed and cannot rotate. Then rotate the movable page 16 to a suitable angle with the fixed shaft 701 as the axis. By tilting the movable page 16 at a certain angle, the heat is discharged in the specified direction. Example 2

[0031] The solution in Example 1 will be further described below with reference to its specific working method.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the flow guiding mechanism 5 further includes a partition plate 503, a curved plate 504, and a filter cylinder 502. The filter cylinder 502 is sleeved and installed on the outside of the outer shell 1, and the filter cylinder 502 is located outside the through hole 15. The width of the filter cylinder 502 is greater than the width of the through hole 15. The filter cylinder 502 is made of stainless steel, and the mesh diameter is 1mm, which can effectively block dust and has good ventilation. The partition plate 503 is uniformly installed in a ring shape inside the outer shell 1, and the partition plate 503 is sleeved and installed outside the through hole 1. The partition 503 is fixedly connected to the outer side of the heat-conducting plate 3 on one side. The length of the partition 503 is the same as the thickness of the heat-conducting plate 3. The curved plate 504 is evenly laid in a ring on one side of the heat-conducting plate 3. One end of the curved plate 504 is fixedly connected to the end of the partition 503. A sealing ring 505 is fixed on one side of the curved plate 504. The outer side of the sealing ring 505 is in contact with the inner wall of the outer shell 1. A guide pipe 501 is fixed in the middle of the sealing ring 505. The other end of the guide pipe 501 is connected to the input end of the cooling fan 4.

[0033] The heat from the spotlight body 2 is transferred to the heat-conducting plate 3. The cooling fan 4 is activated so that the air from the outside passes through the mesh of the filter cylinder 502 and the through hole 15 into the space between the partition plates 503. The heat from the outer wall of the heat-conducting plate 3 is transported to one side of the heat-conducting plate 3 by the air and enters the space between the curved plates 504. The curved shape of the curved plates 504 extends the path length of the air, increases the contact area with one side of the heat-conducting plate 3, and improves the heat exchange efficiency. Then the air gathers towards the middle along the gaps between the curved plates 504 and flows in from the guide pipe 501, and is then discharged from the outside of the outer shell 1 by the cooling fan 4.

[0034] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the limiting member 7 further includes a fixed shaft 701 and a sealing block 702. The fixed shaft 701 is evenly arranged inside the rotating tube 6, and both ends of the fixed shaft 701 are fixedly connected to the inner sidewall of the rotating tube 6. The fixed shaft 701 passes through the top end of the movable page 16 and extends to the bottom end of the movable page 16. The movable page 16 can rotate flexibly around the fixed shaft 701. The sealing block 702 is fixedly sleeved at both ends of the fixed shaft 701, and the sealing block 702 is movably connected to the end of the movable page 16. One side of the sealing block 702 is set as an arc surface, which fits against the arc surface of the inner wall of the rotating tube 6. The sealing block 702 is made of nitrile rubber and contacts both ends of the movable page 16. The elasticity of the rubber generates friction. When the movable page 16 rotates to the required angle, the friction can keep it in that position, thereby achieving angle limiting.

[0035] The limiting component 7 is designed with a fixed shaft 701 and a sealing block 702 to ensure that while the movable page 16 rotates, the sealing block 702 increases the friction between the movable page 16 and its two ends, which facilitates limiting the angle of the movable page 16 after horizontal rotation.

[0036] like Figure 2 As shown, in a preferred embodiment, based on the above method, a washer 13 is fixed on the side of the retaining ring 9 near the outer ring 8, and a washer 24 is fixed on the side of the outer ring 8 near the retaining ring 9. The washer 24 and the washer 13 are movably connected, and the sides of the washer 24 and the washer 13 that are close to each other are both provided with uniformly spaced grooves in an annular shape.

[0037] The design of washer 13, washer 24, and the slot enhances the stability of the outer ring 8 and the retaining ring 9 when they are connected and fitted, and prevents the angle of the rotating tube 6 from shifting after adjustment.

[0038] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a rotating block is fixed at the end of the screw 10 away from the retaining ring 9, and the rotating block is an anti-slip rotating block.

[0039] The anti-slip rotating block at the end of the screw 10 facilitates manual operation and allows for precise control of the screw 10's rotation, improving the convenience and accuracy of wind direction adjustment.

[0040] like Figure 1 and Figure 5 As shown, in a preferred embodiment, based on the above method, the outer side of the rotating tube 6 is further provided with an anti-slip layer, and the anti-slip layer is provided with anti-slip texture.

[0041] The anti-slip layer and texture on the outside of the rotating tube 6 increase the friction of the hand, making it less likely to slip during adjustment and allowing users to quickly adjust the angle of the rotating tube 6.

[0042] like Figure 1 As shown, in a preferred embodiment, based on the above method, a friction-enhancing pad is further fixed on one side of the limiting ring 11, and the friction-enhancing pad is a rubber friction-enhancing pad.

[0043] The rubber friction pad on one side of the limiting ring 11 increases the friction between it and the outer ring 8, making it more secure when fixed and preventing the rotating pipe 6 from loosening and affecting the heat dissipation airflow. Example 3

[0044] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0045] Rotate the limiting ring 11 to move it to the right, and manually push the outer ring 8 to move it to the right, separating the rotating tube 6 from the outer shell 1. Then rotate the outer ring 8, causing the movable leaf 16 and the rotating tube 6 to rotate. At this time, the screw 10 on the retaining ring 9 will slide along the sliding hole 12. After the movable leaf 16 rotates with the rotating tube 6 to a suitable angle, rotate the limiting ring 11 in the opposite direction to move it to the left, pushing the outer ring 8 to the left, so that the rotating tube 6 is tightly attached to and fixed to the outer shell 1, preventing it from rotating. At the same time, the limiting ring 11 is tightly attached to one side of the outer ring 8. Next, with the fixed shaft 701 as the axis, rotate the movable leaf 16 to a suitable angle in sequence. Under the friction of the sealing block 702, the movable leaf 16 is limited when rotated to a suitable angle. After adjusting the tilt and rotation of the movable leaf 16, the heat is directed to the designated direction and discharged.

[0046] The heat generated by the spotlight body 2 is transferred to the heat-conducting plate 3. The cooling fan 4 is activated, and external air enters the space between the partition plates 503 through the mesh of the filter cylinder 502 and the through-holes 15, transferring the heat from the outer wall of the heat-conducting plate 3 to the other side, entering the area of ​​the curved plate 504. The gaps between the curved plates 504 form a curved flow channel, extending the airflow path, increasing the contact area with the heat-conducting plate 3, and improving heat exchange efficiency. Afterwards, the air converges along the gaps between the curved plates 504 in the middle of the heat-conducting plate 3, flows into the guide pipe 501, and is then discharged outside the outer casing 1 by the cooling fan 4.

[0047] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
