Description
Technical Field
[0001] This invention relates to the field of LED lighting fixtures, and in particular to a heat dissipation structure for LED light strips and an LED light strip. Background Technology
[0002] LED light strips have been widely used in various fields such as architectural outline lighting, indoor and outdoor decorative lighting, advertising signs, and automotive lighting due to their advantages such as energy saving, environmental protection, long life, small size, rich colors, and flexibility. As the market demand for high-brightness and miniaturized LED light strips increases, the power density of LED chips continues to increase, and the heat generated also increases dramatically.
[0003] Existing heat dissipation structures typically involve adding heat-conducting metal sheets to heat-generating areas to increase heat dissipation. However, LED strips are usually flexible and bendable, and conventional metal sheets cannot bend with the LED strip, resulting in some LED strips not being completely covered, making it difficult for internal heat to dissipate and causing damage. To solve the above problems, a heat dissipation structure for LED strips and an LED strip are proposed. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that the metal sheet of the existing heat dissipation structure cannot bend with the light strip, making it difficult for internal heat to dissipate and causing damage.
[0005] The present invention adopts the following technical solution:
[0006] A heat dissipation structure for LED light strips includes a mounting frame and at least one heat dissipation part on the mounting frame. The heat dissipation part is attached to the LED light strip through the mounting frame. The mounting frame has mounting grooves on both sides for limiting the heat dissipation part. The opening of the mounting groove is through. The heat dissipation part has a plug-in unit on the outside of the mounting groove. An extension plate is provided on the outside of the plug-in unit. Heat dissipation fins are spliced on one side of the extension plate for conducting the heat absorbed by the heat dissipation part outward.
[0007] Furthermore, the mounting bracket has a slot at the bottom and is made of soft material for fitting onto the flexible light strip and fitting snugly against it. The bottom surface of the mounting bracket has a slot to expose the bottom of the heat dissipation part and allow it to contact the light strip.
[0008] Furthermore, the mounting slots on both sides of the mounting bracket have openings, and the heat dissipation part has locking blocks on both sides. The locking blocks are used to cooperate with the mounting slots to fix the heat dissipation part, and the outer side of the locking blocks has an insertion slot.
[0009] Furthermore, the insertion slot has a limiting groove, the height of which is greater than that of the insertion slot. A central frame is provided in the limiting groove. One end of the central frame is fixedly installed in the limiting groove, and the other end is installed in the middle of the rotating plate via a bearing. A pull plate is provided on the end of the rotating plate near the heat dissipation part via a bearing. The pull plate passes through the limiting groove and extends out. The top of the pull plate has a handle for pulling upwards by hand.
[0010] Furthermore, the plug-in unit includes a plug-in block, the front end of which has a folding stop. The cross-section of the folding stop is a right-angled triangle, with the pointed end mounted on the plug-in block via a pivot. The folding stop has a storage groove on one right-angled side of the plug-in block, and the other right-angled side contacts the sidewall of the limiting groove. The storage groove contains a support structure, which is used to hold the folding stop in place.
[0011] Furthermore, the plug-in unit includes a plug-in block, which mates with the insertion slot and is fixed by bolts;
[0012] Furthermore, a bending portion is provided between the plug-in unit and the extension plate. The width of the bending portion is smaller than the width of the connecting portions on both sides, which is used for adjusting the direction of the extension plate and the heat dissipation fins.
[0013] Furthermore, the support structure adopts an elastic bending plate, one end of which abuts against the storage groove and the other end against the folding block, for supporting the folding block;
[0014] Furthermore, the support structure employs a spring, with one end of the spring abutting against the storage groove and the other end abutting against the folding block, for supporting the folding block;
[0015] Furthermore, the gaps between the heat dissipation fins on the extension plate have connection holes for connecting the bent extension plate to the lamp holder for mounting the light strip.
[0016] Furthermore, an LED light strip is used in conjunction with the heat dissipation structure.
[0017] The beneficial effects of this invention are:
[0018] The mounting bracket is made of soft material, which can fit well on the flexible light strip. The grooved bottom of the mounting bracket and the way it matches the heat dissipation part enable good heat conduction and heat dissipation at all points where the light strip bends. This solves the problem that conventional metal heat sinks cannot bend with the light strip, resulting in some parts of the light strip not being covered for heat dissipation.
[0019] By setting up a dedicated heat dissipation section with an extension plate and fins, the heat conducted from the LED light strip can be effectively dissipated to the outside, avoiding damage to the light strip caused by heat accumulation and extending the lifespan of the LED light strip.
[0020] In the plug-in unit, the folding stop block, under the support of elastic bending plates or springs, is in close contact with the side wall of the limiting groove. Combined with bolt fixing and other methods, the connection between the heat dissipation part and the mounting bracket is firm and stable. During the use of the light strip, even if it is affected by external forces such as vibration and shaking, the heat dissipation structure is not easy to loosen or shift, ensuring the continuous and effective performance of the heat dissipation function.

Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0030] Example 1
[0031] This invention provides a heat dissipation structure for LED light strips, including a mounting frame 1 and at least one heat dissipation part 2 on the mounting frame 1. The number of heat dissipation parts 2 is determined according to the actual mounting frame 1 and the LED light strip 18 it is fitted with. This application does not impose a quantity limit. The bottom of the mounting frame 1 is provided with a slot. The shape of the slot matches the shape of the LED light strip 18, making it easy to fit onto the surface of the light strip. The mounting frame 1 is flexible and can be deformed with the bending of the light strip to ensure a tight fit with the surface of the light strip. The bottom surface of the mounting frame 1 is provided with a slot. The position of the slot corresponds to the heat-generating part of the LED light strip 18, and at the same time, it allows the bottom of the heat dissipation part 2 to directly contact the light strip, improving the heat conduction efficiency. The two sides of the mounting frame 1 are provided with mounting grooves 3. The opening of the mounting groove 3 is through to accommodate the card block 19 of the heat dissipation part 2. The opening design of the mounting groove 3 allows the heat dissipation part 2 to be connected to the plug-in unit 4, and then connected to the extension plate 6 and the heat dissipation fins 7.
[0032] The heat dissipation unit 2 is inserted into the mounting slot 3 of the mounting bracket 1 through the two side clips 19. The outer side of the clip 19 is provided with an insertion slot 8 for accommodating the plug-in unit 4.
[0033] In one embodiment, the insertion slot 8 has a limiting slot 9, and a central frame 10 is provided in the limiting slot 9. One end of the central frame 10 is fixedly provided in the limiting slot 9, and the other end is provided in the middle of the rotating plate 11 through a bearing. A pull plate 12 is provided on one end of the rotating plate 11 near the heat dissipation part 2 through a bearing, and a spring is provided on the other end. The spring contacts the limiting slot 9 to prevent the rotating plate 11 from obstructing the insertion of the insertion unit 4. The pull plate 12 passes through the limiting slot 9 and extends out. The top of the pull plate 12 has a handle 13 for pulling upward by hand.
[0034] The plug-in unit 4 includes a plug-in block 14. The front end of the plug-in block 14 is provided with a folding stop 15. The cross section of the folding stop 15 is a right-angled triangle. Its tip is connected to the plug-in block 14 through a rotating shaft, so that the folding stop 15 can rotate around the rotating shaft. A storage groove 16 is provided on one right-angled side of the folding stop 15. The storage groove 16 is equipped with a support structure such as an elastic bending plate or a spring to support the folding stop 15, so that its other right-angled side contacts the side wall of the limiting groove 9, thereby fixing the heat dissipation part 2.
[0035] In another embodiment, the plug-in unit 4 can be fixed to the insertion slot 8 by bolts, providing a secure connection;
[0036] An extension plate 6 is provided on the outer side of the plug-in unit 4. Fins are spliced on one side of the extension plate 6. The fins can be installed on both sides of the extension plate 6 to increase the heat dissipation area. A bending part 5 is provided between the extension plate 6 and the plug-in unit 4. The width of the bending part 5 is smaller than the width of the connection part on both sides, allowing the direction of the extension plate 6 and the fins to be adjusted to optimize the heat dissipation airflow. There are connection holes in the gaps between the heat dissipation fins 7 on the extension plate 6 for connecting the bent extension plate 6 to the lamp holder for installing the light strip.
[0037] First, fix the LED light strip 18 to the light holder. Align the slot at the bottom of the mounting bracket 1 with the LED light strip and fit it along the length of the light strip so that the bottom surface of the mounting bracket 1 fits tightly against the surface of the light strip. Align the clips 19 on both sides of the heat dissipation part 2 with the mounting grooves 3 through the openings on both sides of the mounting bracket 1 and insert the heat dissipation part 2 along the direction of the mounting grooves 3. Utilize the slots on the bottom of the mounting bracket 1 to allow the bottom of the heat dissipation part 2 to directly contact the light strip, ensuring that heat can be effectively conducted from the light strip to the heat dissipation part 2. Install an appropriate number of heat dissipation parts 2 according to the length of the light strip.
[0038] Insert the plug-in unit 4 into the insertion slot 8 of the card block 19, connect the extension plate 6 to the heat dissipation part 2, and transfer the heat of the light strip to the extension plate 6 and the fins for better heat dissipation.
[0039] Insert the plug block 14 into the insertion slot 8. Since the insertion slot 8 is relatively small, the flip block presses the support structure and screws it into the storage slot 16. When the flip block 15 enters the limiting slot 9, since the limiting slot 9 is relatively large, the flip block 15 extends under the action of the support mechanism. The entire plug unit 4 is clamped in the insertion slot 8 and the limiting block. Through the bending part 5 set between the plug unit 4 and the extension plate 6, its structure is narrower than the connecting parts on both sides. According to the actual heat dissipation requirements and the installation environment, the direction of the extension plate 6 and the heat dissipation fins 7 can be manually adjusted. The bending part 5 can be flexibly bent so that the heat dissipation fins 7 are in a direction that is more conducive to heat dissipation, such as towards a well-ventilated area, thereby improving the heat dissipation efficiency. The connection holes in the gap between the heat dissipation fins 7 on the extension plate 6 can connect the bent extension plate 6 to the lamp holder for installing the light strip.
[0040] When disassembly is required, pull the pull plate 12 outward by using the handle 13. The pull plate 12 causes one end of the rotating plate 11 to rotate around the top of the central frame 10. The other end of the rotating plate 11 rotates downward against the action of the spring piece, pressing against and pressing the inclined part of the folding block 15, pressing the folding block 15 into the storage groove 16, and taking out the plug-in unit 4 outward, and then taking out the extension plate 6 and the heat dissipation fins 7.
[0041] In another embodiment, the plug block 14 is directly inserted into the insertion slot 8 of the card block 19 and fixed with bolts to complete the installation.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The various components mentioned in this invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
