Description

Technical Field

[0001] This utility model belongs to the field of light-emitting device technology, specifically relating to a light-emitting module based on side interference reinforcement. Background Technology

[0002] Light-emitting modules are key components widely used in electronic devices such as LED lighting fixtures. However, with the increase in module power, heat dissipation has become an increasingly significant problem. Currently, cast heat sinks are generally used to improve the heat dissipation performance of light-emitting modules. However, due to the draft angle of the fins in cast heat sinks, the fin length is relatively small and the fin spacing is relatively large, which cannot effectively increase the heat dissipation area and limits the improvement of heat dissipation effect.

[0003] Compared to cast heat sinks commonly used in lighting modules, profile heat sinks do not have draft angles, allowing for longer and more closely spaced fins, thus effectively improving heat dissipation performance. However, due to manufacturing limitations, profile heat sinks cannot be made with annular groove structures, making it difficult to ensure a proper seal between the heat sink and the lens.

[0004] A light-emitting module based on a surround-type lens cover, application number "2023210129418", proposes a module sealing structure. This structure features a plug-in structure on the lens, which is inserted into a slot on a heat sink via an interference fit to assemble and fix the lens to the heat sink. The lens has a downward-facing flange on its periphery. When the lens cover is placed on the heat sink, the flange wraps around the periphery of the heat sink and forms a sealing groove with the side wall of the heat sink. Sealant is applied into the sealing groove to create a seal. However, the structure of this module relies heavily on the plug-in structure on the lens for connection to the heat sink, resulting in relatively low connection strength. Summary of the Invention

[0005] The purpose of this invention is to provide a light-emitting module based on side interference reinforcement.

[0006] This utility model provides a light-emitting module based on side interference reinforcement, including a lens cover, a heat sink, and a light-emitting plate located between the lens cover and the heat sink. The bottom surface of the lens cover has an edge fastening structure. The edge fastening structure includes one or more sets of snap-fit ​​protrusions. Each set of snap-fit ​​protrusions includes two snap-fit ​​protrusions respectively disposed on opposite sides of a set on the bottom surface of the lens cover. The heat sink is located between the two snap-fit ​​protrusions, forming an interference fit.

[0007] Preferably, the bottom of the snap-fit ​​protrusion is provided with a guide structure on the side near the middle of the lens cover to guide the heat sink to be inserted between the two snap-fit ​​protrusions.

[0008] Preferably, the guide structure is a chamfered surface structure.

[0009] Preferably, the snap-fit ​​protrusion has multiple breaks spaced apart sequentially along its length.

[0010] Preferably, the bottom edge of the lens cover has a flange structure that folds downwards and surrounds the lens. The inner side of the flange structure forms a first sealing groove around the lens with the snap-fit ​​protrusion and the side wall of the heat sink. The first sealing groove is filled with sealant.

[0011] Preferably, the inner side of the flange structure is provided with one or more adhesive-containing spaces that are recessed inward from the center of the lens cover.

[0012] Preferably, the bottom surface of the lens cover is further provided with one or more insertion structures; the heat sink is provided with slots corresponding to the insertion structures. The insertion structures are inserted into the corresponding slots to form an interference fit.

[0013] Preferably, the snap-fit ​​protrusion extending along the length of the slot has a notch structure aligned with the insertion structure. The first sealing groove communicates with the slot through the notch structure. The sealant in the first sealing groove enters the slot through the notch structure.

[0014] Preferably, the edge fastening structure includes only one set of snap-fit ​​protrusions disposed on the length side of the bottom surface of the lens cover; the two snap-fit ​​protrusions are located on the inner side of the flange structure. Each insertion structure is located between the two snap-fit ​​protrusions.

[0015] Preferably, multiple plug-in structures are arranged sequentially at intervals. Each plug-in structure includes one or multiple fasteners arranged sequentially at intervals along the extension direction of the corresponding slot.

[0016] Preferably, the plug-in structure has grooves on one or both sides; the slot has protrusions on its sidewalls that match the grooves.

[0017] Preferably, the insertion structure has a groove on only one side; the bottom of the side of the insertion structure without the groove has a first chamfer structure; the bottom of the side wall of the slot without the protrusion has a second chamfer structure. The shapes of the first chamfer structure and the second chamfer structure match each other.

[0018] Preferably, the bottom surface of the lens cover is provided with a second sealing groove that surrounds the entire circumference. The snap-fit ​​protrusion is located outside the second sealing groove. The second sealing groove is filled with sealant.

[0019] The beneficial effects of this utility model are:

[0020] This invention features paired snap-fit ​​protrusions on the lens cover, with the tops of the two opposite sides of the radiator snapped between the two snap-fit ​​protrusions. The elastic bending deformation of the two snap-fit ​​protrusions achieves an interference fit, improving the stability of the connection between the lens cover and the radiator at the edge, strengthening the overall connection strength between the lens cover and the radiator, and effectively reducing the possibility of the lens cover detaching from the radiator.

[0021] This invention features a guide structure at the bottom of the snap-fit ​​protrusions; the guide structure enhances the guiding effect when the radiator is inserted between the two snap-fit ​​protrusions, allowing the radiator to be smoothly inserted between the two snap-fit ​​protrusions.

[0022] This invention features multiple intermittent breaks on the snap-fit ​​protrusions, facilitating deformation of the protrusions and allowing the heat sink to smoothly insert between two protrusions and achieve an interference fit. Simultaneously, the lens cover has a flanged structure on its periphery, forming a first sealing groove between the flanged structure and the side wall of the heat sink. A first sealant is applied into the first sealing groove to achieve a seal. Due to the multiple intermittent breaks on the fasteners, the first sealant flows through the breaks and contacts the heat sink, enhancing the adhesion between the first sealant and the lens cover. This achieves both a sealing function and strengthens the connection.

[0023] This invention features a notch structure in the snap-fit ​​protrusion that aligns with the insertion structure, allowing the first sealing groove separated by the snap-fit ​​protrusion to connect with the slot through the notch structure. This allows the first sealant to flow into the slot for sealing and to bond the insertion structure to the slot.

[0024] This invention features an outwardly protruding structure on the flanged structure, which creates an additional adhesive space on the inner side of the flanged structure. When injecting sealant into the first sealing groove, the sealant can be applied from the adhesive space, and excess sealant can accumulate in the adhesive space.

[0025] This invention features an annular second sealing groove on the bottom surface of the lens cover, into which a second sealant can be injected. The second sealing groove, in conjunction with the first sealing groove, forms a double-layer seal, resulting in a better sealing effect. Furthermore, the second sealant also adheres to the lens and the heat sink. Simultaneously, the second sealant has lower fluidity than the first sealant; sealants with lower fluidity have stronger adhesive force. By using the second sealant to bond the lens and the heat sink, the connection between them is strengthened.

[0026] This utility model has a groove on the side of the plug-in structure and a protrusion on the side wall of the slot that matches the groove; the nesting and cooperation between the protrusion and the groove makes the connection between the lens cover and the heat sink more stable.

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] In the following embodiments, the direction from lens cover 1 to heat sink 2 is taken as the top-to-bottom direction. The top, top, and bottom surfaces of the structure represent the uppermost position of the structure; the bottom, bottom, and bottom surfaces of the structure represent the lowermost position of the structure; the arrangement direction of the heat dissipation fins in the heat sink 2 is taken as the front-to-back direction; and the lateral extension direction of the heat dissipation fins in the heat sink 2 is taken as the left-to-right direction.

[0041] Example 1

[0042] like Figure 1 As shown, a light-emitting module based on side interference reinforcement includes a lens cover 1, a light-emitting plate, and a heat sink 2. The light-emitting plate is clamped and fixed between the mounting surfaces of the lens cover 1 and the heat sink 2. LED beads for emitting light are mounted on the light-emitting plate.

[0043] In this embodiment, the arrangement direction of the heat dissipation fins in the heat sink 2 is the same as the arrangement direction between the two width sides of the heat sink 2; the lateral extension direction of the heat dissipation fins in the heat sink 2 is the same as the arrangement direction between the two length sides of the heat sink 2.

[0044] The bottom surface of the lens cover 1 is provided with an edge fastening structure 3 and multiple insertion structures 4. The edge fastening structure 3 is used to lock the side of the mounting surface of the heat sink 2, improving the connection tightness between the lens cover 1 and the edge of the heat sink 2. The multiple insertion structures 4 are arranged sequentially at intervals along the front-to-back direction. The mounting surface of the heat sink 2 is provided with multiple slots 21 that correspond one-to-one with the insertion structures 4. The slots 21 extend along the left-right width direction of the heat sink 2 and penetrate through the left and right edges of the heat sink 2, forming a groove structure with open ends. The insertion structure 4 is inserted into the corresponding slot 21 to form an interference fit; the light-emitting plate is provided with a clearance groove structure that matches the insertion structure 4 to prevent the insertion structure 4 from being blocked by the light-emitting plate.

[0045] In this embodiment, the edge fastening structure 3 is only provided on the two long sides of the bottom surface of the lens cover 1, forming an interference fit with the top of the left and right sides of the heat sink 2 to strengthen the structural strength on the left and right sides (i.e., the two long sides) of the light-emitting module. The structural strength on the front and rear sides (i.e., the two width sides) of the light-emitting module is ensured by the plug-in structure 4 located at the front and rear ends of the bottom surface of the lens cover 1.

[0046] The bottom edge of the lens cover 1 has a flange structure 11 that folds downward and wraps around the entire perimeter. The edge fastening structure 3 includes two snap-fit ​​protrusions 31. The two snap-fit ​​protrusions 31 are located inside the flange structure 11 and are close to the two long sides of the flange structure 11, respectively. Each insertion structure 4 is located between the two snap-fit ​​protrusions 31.

[0047] The initial distance between the two snap-fit ​​protrusions 31 (i.e., the distance between the lens cover 1 and the heat sink 2 when they are not assembled together) is less than the width of the mounting surface of the heat sink 2. The opposite sides of the two snap-fit ​​protrusions 31 contact the left and right sides of the heat sink 2 respectively, and elastically bend outward under the push of the left and right sides of the heat sink 2 to form an interference fit. The interference fit between the two snap-fit ​​protrusions 31 and the left and right sides of the heat sink strengthens the connection between the lens cover 1 and the heat sink 2 on the basis of the interference plug structure 4, making the connection more stable and the lens cover 1 less likely to fall off the heat sink 2.

[0048] To facilitate the smooth insertion of the heat sink 2 between the two snap-fit ​​protrusions 31, a concave guide structure 34 is provided on the bottom side of the snap-fit ​​protrusions 31 near the middle of the lens cover 1. The guide structure 34 is specifically a chamfered structure, which guides the two snap-fit ​​protrusions 31 to gradually bend and deform outward elastically when the top of the heat sink 2 is inserted between the two snap-fit ​​protrusions 31, ensuring a stable connection between the lens cover 1 and the heat sink 2.

[0049] In some preferred embodiments, each of the two snap-fit ​​protrusions 31 is provided with a plurality of breaks 32 arranged sequentially at intervals along the front-to-back direction. The snap-fit ​​protrusions 31 with complete breaks 32 are separated into independent snap-fit ​​plates. By breaking the snap-fit ​​protrusions 31, the snap-fit ​​protrusions 31 can be made more easily deformed, thereby ensuring that the heat sink 2 can be smoothly inserted between the two snap-fit ​​protrusions 31 and achieve an interference fit.

[0050] When the lens cover 1 is placed on the heat sink 2, the inner side of the flange structure 11 forms a first sealing groove 5 around the radiator 2 with the snap-fit ​​protrusion 31 and the side wall of the heat sink 2. First sealant is injected into the first sealing groove 5 to achieve a seal. Because the snap-fit ​​protrusion 31 has multiple breaks 32 spaced apart, the first sealant can flow in through the breaks 32 and contact the heat sink 2. The first sealant bonds the lens cover 1 to the heat sink 2, achieving a sealing function while also strengthening the connection.

[0051] The snap-fit ​​protrusion 31 is also provided with a notch structure 33 that aligns with the multiple plug-in structures 4 located in the middle. When the plug-in structure 4 is inserted into the corresponding slot 21, the first sealing groove 5 separated by the snap-fit ​​protrusion 31 is connected to the slot 21 through the notch structure 33, so that the first sealant flows into the slot 21 to seal it and bond the plug-in structure 4 to the slot 21.

[0052] The bottom surface of the lens cover 1 is provided with a raised strip that surrounds the entire surface. The raised strip breaks at the bend; the raised strip is located between two snap-fit ​​protrusions 31. The raised strip surrounds the light-emitting plate. The raised strip is used to elevate the center of the bottom surface of the lens cover 1, leaving installation space for the light-emitting plate. The outer side of the raised strip is provided with a recessed second sealing groove 12 that surrounds the entire surface. The second sealing groove 12 is located between the two snap-fit ​​protrusions 31.

[0053] A second sealant can be injected into the second sealing groove 12. The second sealing groove 12, together with the first sealing groove 5, forms a double seal, resulting in a better sealing effect. The second sealant also has an adhesive effect on the lens 1 and the heat sink 2. In this design, the flowability of the second sealant is lower than that of the first sealant. The sealant with lower flowability has stronger adhesive force. By using the second sealant to bond the lens 1 and the heat sink 2, the connection between the two is strengthened.

[0054] The flange structure 11 has one or more outwardly protruding structures 13 that rise away from the center of the lens cover 1. The thickness of the outwardly protruding structure 13 is the same as the thickness of the rest of the flange structure 11, forming an additional adhesive space on the inner side of the flange structure 11. When injecting sealant into the first sealing groove 5, the sealant can be applied from the adhesive space formed by the outwardly protruding structure 13, and excess sealant can accumulate in the adhesive space.

[0055] The plug-in structure 4 includes multiple fasteners arranged sequentially at intervals along the left-right direction (i.e., the width direction of the lens cover); all fasteners are inserted into the corresponding slots 21 on the heat sink and form an interference fit.

[0056] In the same plug structure 4, the two fasteners arranged at both ends overlap with the padding strips located on the two length sides of the lens cover 1.

[0057] In all the plug-in structures 4, the fasteners of the plug-in structures 4 at both ends overlap with the padding strips located on the two width sides of the lens cover 1.

[0058] In some embodiments, a groove 41 is provided on one side wall of the fastener; a protrusion 22 is provided on the side wall of the slot 21 corresponding to the groove 41. Among the front and rear side walls of the fastener, the side wall with the groove 41 is called the first engaging side, and the side wall without the groove 41 is called the yielding side; among the two slot walls of the slot 21, the slot wall with the protrusion 22 is called the second engaging side, and the side wall without the groove 41 is called the compensation side.

[0059] In some embodiments, the longitudinal cross-sectional profile of the protrusion 22 is an arc with a radius of 0.8 mm to 1.2 mm (preferably 1 mm). The outward protrusion height of the protrusion 22 is 0.3 mm to 0.4 mm (preferably 0.3 mm); the outward protrusion height is the distance between the point on the protrusion 22 furthest from the plane of the slot sidewall and the plane of the slot sidewall.

[0060] In some embodiments, the protrusion 22 is a continuous strip with both ends extending to the two sides of the radiator 2.

[0061] The fastener has a recessed first chamfer structure 42 at the bottom of its clearance side; the slot 21 has a second chamfer structure 23 at the bottom of its compensation side. The shapes of the first chamfer structure 42 and the second chamfer structure 23 match each other. During the process of inserting the fastener into the groove 41, the bottom of the first snap-fit ​​side of the fastener contacts the protrusion 22 on the second snap-fit ​​side of the slot 21, causing the fastener to bend and deform. The recessed first chamfer structure 42 on the clearance side of the fastener provides clearance, allowing the fastener to bend and deform smoothly and be inserted into the slot 21. After the fastener is fully inserted into the corresponding slot, the first chamfer structure 42 and the second chamfer structure 23 fit together, avoiding the formation of a sealing structure with excessive gaps.

[0062] In some further embodiments, the first chamfer structure 42 and the second chamfer structure 23 are both inclined plane structures; in other embodiments, the first chamfer structure 42 and the second chamfer structure 23 may also be curved surface structures.

[0063] In some embodiments, the radiator 2 is a profile obtained by aluminum alloy extrusion molding.

[0064] In some embodiments, the light-emitting board includes a PCB board and a plurality of LED chips distributed on the PCB board. A plurality of lens units are integrally formed on the lens cover 1. The position of each lens unit corresponds to the position of each LED chip on the light-emitting board, and is used to distribute the light emitted by the LED chips. The mounting surface of the heat sink 2 is attached to the light-emitting board; the power supply line of the light-emitting board is led out through the wire hole in the middle of the heat sink 2.

[0065] In some embodiments, to facilitate the insertion of fasteners into the slot 21, the top edge of the slot 21 is provided with a rounded chamfer.

[0066] Example 2

[0067] A light-emitting module based on side interference reinforcement. The difference between this embodiment and embodiment 1 is that the edge fastening structure 3 is different.

[0068] In this embodiment, the edge fastening structure 3 includes four snap-fit ​​protrusions 31. The four snap-fit ​​protrusions 31 are located on the inner sides of the two length sides and the two width sides of the flange structure 11, respectively. After the heat sink is inserted, the four snap-fit ​​protrusions 31 abut against the top of the four sides of the heat sink and bend and deform, thereby comprehensively improving the tightness of the lens cover and the heat sink around the perimeter.

[0069] Example 3

[0070] A light-emitting module based on side interference reinforcement is described in this embodiment, which differs from Embodiment 1 in that it does not include the plug-in structure 4 and slot 21. In this embodiment, screws are used instead of fasteners and slot 21 to securely connect the center of the lens cover to the heat sink.

[0071] Example 4

[0072] A light-emitting module based on side interference reinforcement. The difference between this embodiment and embodiment 1 is that the fasteners and slots 21 of the plug-in structure 4 are different.

[0073] like Figure 9 and Figure 10 As shown, in this embodiment, the fastener of the plug-in structure 4 does not have a first chamfer structure 42; the slot 21 does not have a second chamfer structure 23 on its groove wall. Both sides of the fastener are provided with grooves 41; both groove walls of the slot 21 are provided with protrusions 22.

[0074] In some embodiments, the bottom of the fastener is provided with a slot 43 to provide space for the fastener to contract inward; the slot 43 extends from the bottom of the fastener (specifically the end away from the lens cover 1) to the top. In some further embodiments, in the same insertion structure 4, on the two fasteners arranged at the left and right ends of the lens cover 1, the opening of the slot 43 on the side away from the middle position of the lens cover 1 is provided with a closing structure, so that the two fasteners arranged at the left and right ends can close the slot.

[0078] like Figure 11 As shown, in this embodiment, the fastener of the plug-in structure 4 does not have a groove 41; the slot 21 does not have a protrusion 22 on its wall. The bottom of the fastener has a slot 43 that provides space for the fastener to shrink and deform inward.
