Description

Technical Field

[0001] The utility model belongs to the technical field of light-emitting equipment, and in particular relates to a slot buckle-type light-emitting module. Background Art

[0002] The light-emitting module is an indispensable key component in electronic devices such as LED lamps. As the power of the module increases, the heat dissipation problem becomes more prominent. At present, cast heat sinks are generally used to improve the heat dissipation performance of the light-emitting module. However, the fins of the cast heat sink have a draft angle, resulting in a shorter fin length and a larger spacing, which limits the increase in the heat dissipation area and thus limits the improvement in the heat dissipation effect.

[0003] Compared with the commonly used cast heat sinks, the heat sink prepared by profiles does not have a draft angle, so longer and denser heat sink fins can be manufactured, effectively improving the heat dissipation performance. However, due to processing reasons, the profile heat sink cannot produce an annular groove structure, which makes it difficult to ensure the sealing effect between the heat sink and the lens. Therefore, how to solve the problem of lens sealing while meeting the heat dissipation performance has become a difficult problem that needs to be solved urgently in the field of light-emitting modules. At the same time, the lens plate installation method using interference fit and other forms has high requirements on the dimensional accuracy of the plug on the lens plate and the slot on the heat sink. Summary of the invention

[0004] The utility model aims to provide a slot buckle type light emitting module.

[0005] The utility model provides a slot-locked light-emitting module, comprising a lens plate, a light-emitting plate and a heat sink, and a plurality of snap-on fastening structures connected to the lens plate.

A sealing groove surrounding the lens body is formed between the inner edge of the annular structure, the outer edge of the lens body and the heat sink. The sealing groove is filled with sealant.

[0011] Preferably, the clamping fastening structure comprises a main fastener and two end fastening blocks. The two end fastening blocks are arranged on the annular structure; the main fastener is arranged on the lens body; and the main fastener is located between the two end fastening blocks.

[0012] Preferably, a first guiding slope is provided at the top edge of the side wall of the slot where the second clamping portion is provided.

[0013] Preferably, a fitting slope is provided at the position where the end fastening block is connected to the lens plate. The shape and position of the fitting slope match the first guiding slope. The fitting slope on the end fastening block fits with the first guiding slope on the slot.

[0014] Preferably, a second guiding slope is provided on the outer side of the first hook on the main fastener.

[0015] Preferably, the thickness L1 of the outer end of the main fastener including the first hook is less than or equal to the width L3 of the position where the second hook is located on the slot.

[0016] Preferably, the outer end of the end fastening block is provided with an intermediate groove; the thickness of the outer end of the end fastening block is greater than or equal to the bottom width of the slot, so that when the end fastening block is inserted into the slot, the two side surfaces of the end fastening block are in contact with the bottom of the two side walls of the slot respectively.

[0017] Preferably, the clamping fastening structure further comprises two rubber stoppers. The two rubber stoppers are respectively arranged at the two side edges of the inner side of the lens body.

The main fasteners in the remaining clamping and fastening structures are of a segmented structure. The protrusion height of any lens unit of the lens board constrained by each clamping and fastening structure during use is less than a threshold value.

[0020] The beneficial effects of the utility model are:

[0021] 1. The utility model provides a slot with two through ends on the profile, and provides mutually matching snap-fit ​​structures on the slot and the lens plate, thereby replacing the connection methods such as the screws on the periphery of the lens plate and the snap-fit ​​frame connection. The production is more convenient and other parts such as screws are not required. In addition, the snap-fit ​​connection method has lower requirements on the dimensional accuracy of the slot and the snap-fit ​​fastening structure.

[0022] 2. The utility model provides constraints on different positions of the lens plate by setting a plurality of mutually matching slots and snap-on fastening structures at different positions between the heat sink and the lens plate, which can avoid the problem of the middle part of the lens plate bulging during long-term use, and can make the lens plate evenly apply pressure to different positions of the PCB board, so that the PCB board and the heat sink fit more closely, the contact area is larger, and the heat dissipation effect is better. At the same time, the uniform force can make the PCB board less likely to warp, and a thinner PCB board can be used; and because the entire bottom surface of the lens plate is tightly pressed against the light-emitting board, the utility model also improves the tolerance of the surface flatness of the light-emitting board, and does not need to process the flatness of the PCB surface, further reducing the production cost.

[0023] 3. The utility model sets a through sealing groove on the lens plate, and seals the joint between the radiator and the lens plate by applying glue in the sealing groove, so as to achieve excellent waterproof sealing effect when using a profile radiator, and can also fix the lens plate. This sealing method does not require a sealing ring, which is more conducive to automated production, higher production efficiency and lower production cost. The reason is that the sealing ring is soft, changeable and difficult to control in size. During automation, the robot cannot grab and place the sealing ring, so the step of placing the sealing ring cannot be automated. At the same time, the absence of the sealing ring is also conducive to cost saving. In addition, because the sealing ring is eliminated, the light-emitting area of ​​the lens plate becomes larger and the screen-to-body ratio is larger. At the same time, the second clamping parts in the radiator prepared by the profile forming process of the utility model are parallel to each other and extend in the same direction, so the cost is relatively low and the corrosion resistance is good.

[0024] 4. The utility model provides a first guiding slope at the slot opening, so that the clamping fastening structure can be easily inserted into the slot. At the same time, the utility model provides a fitting slope matching the first guiding slope at the connection between the end fastening block and the lens plate to avoid affecting the sealing problem after subsequent gluing.

[0025] 5. The utility model reduces the width of the main fastener to facilitate the insertion of the main fastener into the slot for fixation. On the other hand, the utility model provides a rubber stopper to prevent the sealant from flowing into the slot below the lens body and causing waste of the sealant.

[0033] The utility model is further described below in conjunction with the accompanying drawings.

[0034] Example 1

[0035] like Figure 1 As shown, a slot-locked light-emitting module includes a lens plate 1, a light-emitting plate 2, a heat sink 3, and a plurality of snap-on fastening structures 4 integrally formed on the lens plate 1. The light-emitting plate 2 is fixed between the lens plate 1 and the heat sink 3 and is squeezed. The light-emitting plate 2 is tightly attached to the bottom surface of the lens plate 1, which can avoid a gap between the bottom surface of the lens plate and the light-emitting plate 2, so that the light distribution of the lens plate is more accurate and the light output rate of the module is also higher.

[0036] like Figure 3 As shown, the lens plate 1 includes a lens body 1-1 and an annular structure 1-2. The annular structure 1-2 surrounds the lens body 1-1 and is spaced apart from the outer edge of the lens body 1-1; a plurality of snap-on fastening structures 4 are disposed on the lens body 1-1 and the annular structure 1-2, and are sequentially spaced apart along the length direction of the lens plate 1. The lens body 1-1 and the annular structure 1-2 are connected by a connecting section 1-3 to realize an integrated structure between the lens body 1-1 and the annular structure 1-2.

[0037] like Figure 2 As shown, the heat sink 3 is provided with slots 3-1 equal in number to and corresponding to the snap-fastening structures 4. The slots 3-1 extend along the width direction of the heat sink 3 and penetrate the left and right edges of the heat sink 3. The snap-fastening structures 4 can be inserted into the corresponding slots 3-1 on the heat sink 3 and snap-fastened, so that multiple different positions of the lens body 1-1 are fixed to the heat sink 3.

[0038] The power supply line of the light-emitting panel 2 is led out through the wire hole on the heat sink 3. The heat dissipation surface of the heat sink 3 is provided with heat dissipation fins arranged at intervals. In this embodiment, the heat sink 3 is made of extruded aluminum profiles; compared with die-casting, aluminum profiles can produce more dense and longer fins. In some other embodiments, the heat sink 3 can also be made of metal parts made by other processes such as die-casting.

[0039] like Figure 4 and Figure 5As shown, the length direction of the clamping fastening structure 4 itself is parallel to the width direction of the lens plate 1, and it includes a main fastener 4-1, two rubber stops 4-2 and two end fastening blocks 4-3. The two end fastening blocks 4-3 are respectively arranged on both sides of the inner side of the annular structure 1-2; the main fastener 4-1 is arranged on the lens body 1-1; the two rubber stops 4-2 are respectively arranged at the two side edges of the inner side of the lens body 1-1. The main fastener 4-1 is arranged between the two rubber stops 4-2 in the width direction of the lens plate 1. The two rubber stops 4-2 are located between the two end fastening blocks 4-3. The longitudinal cross-sectional shapes of the rubber stops 4-2 and the end fastening blocks 4-3 are the same.

[0040] In some embodiments, the connecting section 1-3 for connecting the lens body 1-1 and the annular structure 1-2 is disposed between the rubber stopper 4-2 and the end fastening block 4-3 facing each other. The two ends of the connecting section 1-3 are respectively connected to the corresponding rubber stopper 4-2 and the opposite side of the end fastening block 4-3 to form an integrated structure. The connecting section 1-3 is completely in the slot 3-1 and does not contact the slot 3-1.

[0041] A first clamping portion 4-4 is provided on the side of the clamping fastening structure 4. A second clamping portion 3-1-1 is provided on a side wall of the slot 3-1. The shape of the first clamping portion 4-4 matches the shape of the second clamping portion 3-1-1 and can be snapped together. Specifically, the first clamping portion 4-4 is provided on the side of the mutually independent end fastening block 4-3, the rubber stopper 4-2 and the main fastener 4-1 of the clamping fastening structure 4.

[0042] In this embodiment, the first clamping portion 4-4 includes a first clamping hook formed by protruding from one side of the outer end of the clamping fastening structure 4, and a first clamping groove formed between the first clamping hook and the lens body 1-1 and the annular structure 1-2. The second clamping portion 3-1-1 includes a second clamping hook formed by protruding from the side wall of the slot 3-1 near the top opening, and a second clamping groove formed between the second clamping hook and the bottom surface of the slot 3-1.

[0043] like Figure 6 and Figure 7 As shown, when the snap-fastening structure 4 and the main fastener 3 are inserted into the corresponding slot 3-1, the first hook of the first snap-fastening portion 4-4 is buckled into the second slot of the second snap-fastening portion 3-1-1 to form a snap-fastening connection. In order to facilitate the insertion of the main fastener 4-1 and the end fastening block 4-3 into the slot 3-1 to achieve snap-fastening, the slot 3-1 is provided with a first guide slope 3-1-2 at the top edge of the side wall of the second snap-fastening portion 3-1-1.

[0044] In some embodiments, the thickness of the main fastener 4-1 is different from that of the end fastening block 4-3. Among them, the thickness L1 (specifically, the maximum dimension along the length direction of the light-emitting module) of the outer end of the main fastener 4-1 including the first hook is smaller than the width L2 of the position of the hook on the slot 3-1. As a result, when the main fastener 4-1 is inserted into the slot 3-1, there is a gap between the side of the main fastener 4-1 where the first clamping portion 4-4 is not provided and the side wall of the slot 3-1 where the second clamping portion 3-1-1 is not provided. Based on this, when the main fastener 4-1 abuts against the inclined surface 42, the main fastener 4-1 can be deformed to facilitate insertion into the slot 3-1. After the end fastening block 4-3 is inserted, the main fastener 4-1 resets and rebounds, and the first clamping portion 4-4 is buckled into the second clamping portion 3-1-1 to achieve buckling.

[0045] In some embodiments, a second guiding slope is provided on the outer side of the first hook on the main fastener 4 - 1 , so that the main fastener 4 - 1 and the first engaging portion 4 - 4 thereon can enter the slot 3 - 1 more smoothly.

[0046] The longitudinal cross-sectional shape of the end fastening block 4-3 matches the longitudinal cross-sectional shape of the slot 3-1. Specifically, the thickness L3 of the outer end of the end fastening block 4-3 including the first hook is greater than or equal to the width L4 of the bottom of the slot 3-1, so that the end fastening block 4-3 can effectively close the end of the slot 3-1.

[0047] A fitting bevel 4-3-1 is provided at the position where the end fastening block 4-3 is connected to the lens body 1-1 and the annular structure 1-2. The size of the fitting bevel 4-3-1 matches the first guiding bevel 3-1-2. When the end fastening block 4-3 is fully inserted into the slot 3-1, the two side surfaces of the end fastening block 4-3 are in contact with the bottom of the two side walls of the slot 3-1 respectively. The fitting bevel 4-3-1 on the end fastening block 4-3 is tightly fitted with the first guiding bevel 3-1-2 on the slot 3-1.

[0048] In order to smoothly insert the end fastening block 4-3 into the slot 3-1, the outer end of the end fastening block 4-3 (i.e., the end away from the lens plate 1) is provided with a slot 4-3-2; during the insertion of the end fastening block 4-3 into the slot 3-1, both sides of the outer end of the end fastening block 4-3 are squeezed and deformed into the slot 4-3-2, so that the first hook of the first clamping part 4-4 on the end fastening block 4-3 can enter the bottom of the slot 3-1 and rebound, so that the first clamping part 4-4 is buckled into the second clamping part 3-1-1 to achieve buckling. The width of the slot 4-3-2 is greater than the thickness of the first hook, so as to provide sufficient deformation space for the end fastening block 4-3.

[0049] The light-emitting board 2 includes a PCB board and a plurality of lamp beads distributed on the PCB board. A plurality of lens units are integrally formed on the lens body 1-1. The position of each lens unit corresponds to the position of each lamp bead on the light-emitting board 2, and is used to distribute the light emitted by the lamp bead. A clearance groove is provided at a position corresponding to the main body fastener 4-1 on the light-emitting board 2, so that the main body fastener 4-1 can pass through the light-emitting board 2.

[0050] After the buckling is completed, the lens plate 1 is tightly attached to the light-emitting board 2, and the lens plate 1 presses the light-emitting board 2 onto the heat sink 3; the clamping fastening structure 4 in the middle of the lens plate 1 can pull the middle position of the lens body 1-1 to prevent the middle part of the lens body 1-1 from bulging and deforming, and a gap is generated between the lens plate 1 and the light-emitting board 2, so that the lens plate 1 maintains high accuracy of light distribution during long-term use, and the light output rate of the light-emitting module is maintained at a high level. It should be noted that due to the heat generated during the operation of the light-emitting module, the air pressure inside and outside the lens plate 1 will be inconsistent. When the connection between the lens plate 1 and the heat sink 3 is not tight enough, the lens plate 1 will be separated from the light-emitting board 2, affecting the sealing effect of the light-emitting module and affecting its light distribution accuracy.

[0051] In addition, the light-emitting module provided in this embodiment is assembled by pressing, which avoids possible breakage caused by unnecessary stress compared to the fixing method of screws; and the integrated design of this embodiment will not produce holes, and there is no extra gap, so the sealing effect is good. At the same time, no extra main fasteners are required, which is convenient for automatic installation.

[0052] It should be noted that the number of main fasteners 4-1 is not limited under the condition that the lens plate 1 does not arch and separate from the light-emitting plate 2. In some embodiments, the light-emitting plate is located between the clamping fastening structures 4 arranged at both ends of the lens plate 1; the main fasteners 4-1 in the clamping fastening structures 4 arranged at both ends of the lens plate 1 are of an integral structure; the main fasteners 4-1 in the remaining clamping fastening structures 4 are of a segmented structure, divided into three or more fastening block units arranged in sequence, so as to prevent the clamping fastening structures 4 from completely isolating the light-emitting plate 2.

[0053] After the lens plate 1 is buckled and installed, a sealing groove 1-4 surrounding the lens body 1-1 is formed between the inner edge of the annular structure 1-2, the outer edge of the lens body 1-1 and the installation surface of the heat sink, and the sealing groove 1-4 is connected to the slot 3-1. Sealant is applied in the sealing groove 1-4, and the sealant can flow into the slot 3-1 for sealing. The sealing groove 1-4 is filled with the sealant that flows into the slot 3-1.

[0054] In this embodiment, the glue stopper 4 - 2 is used to prevent the sealant from flowing into the middle area of ​​the slot 3 - 1 located below the lens body 1 - 1 , causing waste of the sealant.

[0055] In some embodiments, the first clamping parts 4-4 on all the clamping and fastening structures 4 are located at the center of the clamping and fastening structures 4 close to the lens plate 1. The unlocking bending directions of the first clamping parts 4-4 on both sides of the center of the lens plate 1 are opposite, thereby improving the reliability of the connection between the lens plate 1 and the heat sink 3. In some further embodiments, the number of the clamping and fastening structures 4 is an even number; the clamping and fastening structures 4 on both sides of the center of the lens plate 1 form a symmetrical structure, so that during the insertion of the clamping and fastening structures 4 into the slot 3-1 on the heat sink 3, the force of the lens plate 1 in the horizontal direction is balanced, so that only a downward squeezing force needs to be applied to the lens plate 1 to complete the snap-fit ​​installation. The bulge height of any lens unit of the lens plate 1 constrained by each clamping and fastening structure 4 during use is less than a threshold value; the threshold value is used to ensure that the lens unit maintains an effective light distribution effect during long-term use. The spacing between adjacent clamping and fastening structures 4 is adjusted according to the material properties of the lens plate 1 to meet the requirement that the bulge height is less than the threshold value.
