Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a sealed assembled light source module. Background Technology

[0002] In the field of LED linear lighting, a wired power connection scheme is often used when splicing multi-source light source modules. Existing technology has the following drawbacks: 1. Traditional heat sinks have through-hole designs for the wire holes (such as the heat sink disclosed in patent publication number CN209819312U). After wire insertion, adhesive needs to be applied to the back of the heat sink for sealing. As the adhesive ages, water can easily seep from the edges of the wire holes; furthermore, the sealant covers the heat dissipation path, leading to increased thermal resistance. 2. During splicing, the power cables are exposed on the mounting plate, making them prone to being crushed during sliding assembly of the mating crimping parts, resulting in a high failure rate. 3. Air tightness testing is difficult; traditional water-based testing methods require disassembling the module, leading to a low pass rate for re-inspection.

[0003] Therefore, how to achieve a fully integrated sealed assembly light source module that combines permanent sealing of the wire hole area, non-destructive assembly, and online airtightness testing is a challenge. Summary of the Invention

[0004] To address the shortcomings and deficiencies of existing technologies, this utility model aims to provide a sealed assembly light source module. This module achieves permanent waterproof sealing, zero-damage assembly, and integrated online airtightness testing through a dual-function sealing system of bottom-sealed wire holes, dynamic avoidance of temporary storage slots, and bottom perforations.

One end of the first elongated pressure plate has a clamping groove for receiving the end of a cover plate, and the two first claw portions are respectively inserted into two sliding grooves on both sides of the mounting plate; and The mating crimping member installed on the mating end includes a second elongated pressure plate. Both ends of the second elongated pressure plate extend downward to form crimping portions. The lower ends of the two crimping portions are provided with side wall slide rails facing each other. Both ends of the second elongated pressure plate are provided with crimping grooves to accommodate the ends of the cover plate. The two side wall slide rails are respectively inserted into two slide grooves on both sides of the mounting plate.

Detailed Implementation

[0019] This utility model provides a sealed assembly light source module. By setting a bottom-sealed wire hole on the heat sink mounting plate and innovatively designing a channel hole connecting the wire hole and a vertical through hole, a triple waterproof seal is achieved with an interference-fit silicone sealing plug. To address assembly pain points, a temporary storage groove is extended outside one of the wire holes, so that the wire is completely hidden when the sliding path of the mating crimping part covers the temporary storage groove, thus completely solving the technical problems of water seepage and cable damage during assembly in traditional wiring structures.

[0020] The following embodiments further illustrate the content of this utility model, but should not be construed as limiting the utility model. Any modifications or substitutions made to the methods, steps, or conditions of this utility model without departing from its spirit and essence are within the scope of this utility model.

[0021] This utility model provides a sealed, assembled light source module, including a heat sink 1 and at least two sets of light source components 2 mounted on the heat sink 1. Please refer to... Figures 1 to 4 The mounting plate 11 of the heat sink 1 has two bottom-closed wire holes 12 and 12a at the mating end of the adjacent light source assembly 2, meaning that the wire holes 12 and 12a do not penetrate the mounting plate. The two wire holes 12 and 12a are connected by a channel hole 13. A downward through hole 14 is provided on the mounting plate 11 between the two wire holes 12 and 12a. This downward through hole 14 vertically connects to the channel hole 13, and a sealing plug 5 is interference-fitted into the downward through hole 14. (Refer to...) Figure 5 The sealing plug 5 is preferably made of silicone, and its diameter is 0.05mm larger than that of the lower perforation 14 to achieve a tight seal. Traditional radiator wire holes are through-hole designs, requiring glue to be poured and sealed on the back of the radiator after the wire is threaded. As the glue ages, water can easily seep from the edge of the wire hole, resulting in poor waterproofing reliability. In this embodiment, the bottom of the wire hole is sealed, eliminating water seepage from the back.

[0022] The depth H1 of the wire holes 12 and 12a satisfies: H1 ≥ 1.5 times the diameter of the power line; it is used to accommodate the power line. The lower through hole 14 connects to the channel hole 13. The wire hole size is small, and it is impossible to open the two wire holes 12 and 12a from the wire hole side during processing. The lower through hole 14 serves as a process hole for machining the channel hole with a T-shaped milling cutter during processing, ensuring the yield rate of the channel hole 13 process. The sealing plug of the lower through hole 14 can be made of an elastic material plug structure, preferably silicone.

[0023] refer to Figure 2 , Figure 4 As shown, the outer wall of one of the wire holes 12a extends outward to form a temporary storage groove 15. The length L of the temporary storage groove 15 is not less than the straight-line distance from the power terminal 211 of the corresponding light source assembly 2 to the center of the wire hole 12a. For example, when the center distance between the terminal 211 and the wire hole 12a is 20mm, the length of the temporary storage groove 15 is at least 20mm, thereby ensuring that the temporary storage groove 15 can completely accommodate the power cord at that end. The depth H2 of the temporary storage groove 15 satisfies: H2 ≥ 1.3 times the diameter of the power cord; to facilitate the passage of the power cord, the bottom of the groove is a smooth curved surface to avoid wire wear.

[0024] It should be noted that, according to the IP protection level requirements of LED lighting fixtures, the light-emitting area and electrical connection area inside the light source assembly must be completely sealed and isolated. Specifically, in existing lighting fixtures, the working surface of the LED beads, the power terminal, and the cable routing path of the light source assembly must all form a sealed cavity with the mounting plate of the heat sink through a sealed structure. In this utility model, the sealed cavities of the two light source assemblies are connected and wired through a sealed channel hole. The two light source assemblies on both sides are securely connected at the joint and the lower through hole 14 is sealed. This utility model uses a joint crimping piece 25 to press the ends of the joined light source assemblies onto the mounting plate of the heat sink 1. The joint crimping piece 25 is positioned exactly above the lower through hole 14, as shown in the reference. Figure 6 , Figure 7 .

[0025] The mating crimping member 25 is slidably mounted on the two long side walls of the radiator 1 via side wall slide rails 251 on both sides. For example... Figure 7 As shown, the sliding path of the mating crimping member 25 passes directly above the temporary storage groove 15. When the mating crimping member 25 slides to the mating end position, the crimping parts 252 on both sides press the side ends of the two sets of light source assemblies 2 onto the mounting plate 11.

[0026] Each of the aforementioned light source components 2 includes a circuit board 21 and a cover plate 22. Each cover plate 22 seals the circuit board between the cover plate 22 and the heat sink by means of a sealing ring 29 and a fixing assembly, such as... Figure 8As shown, the cover plate 22 presses the circuit board 21 onto the mounting plate 11 of the heat sink 1 to form a sealed space. Power terminals 211 are provided at both ends of the circuit board 21, and wire holes 12 and 12a are positioned close to the corresponding terminals 211. The power cable 4 is led out from one terminal, enters the wire hole 12, passes through the channel hole 13, and exits from the other wire hole 12a, connecting to the other terminal. Because the lower through hole 14 is press-fitted with the sealing plug 5, the power connection lines outside the light source assembly are kept within the sealed space.

[0027] The mounting plate 11 of the radiator 1 is rectangular, with a through-groove 104 formed on its long side wall. The cover plate 22 has a recessed mounting groove 221 on its long side. The fixing assembly includes two first sliding members 23 and a second sliding member. The first sliding member 23 is a long strip formed along the long side of the radiator 1. The upper and lower long sides of the first sliding rail 231 are respectively provided with a first sliding rail 231 and a second sliding rail 232 facing the same side. The first sliding rail 231 is inserted into the groove 104, and the second sliding rail 232 is pressed into the mounting groove 221 of the cover plate 22. The terms "upper" and "lower" refer to the position of the light fixture in its operational state.

[0028] The second sliding member includes two types: end pressing member 24 and butt pressing member 25. The end pressing member 24 is correspondingly disposed at both ends of the heat sink 1. The end pressing member 24 includes a first elongated pressing plate 241 at one end that presses against the side wall of the light source assembly, and two first claw portions 242 extending downward from both ends of the pressing plate. One end of the first elongated pressing plate 241 is provided with a pressing groove 248 for accommodating the end of the cover plate 22. The two first claw portions 242 are respectively inserted into the two sliding grooves 104 on both sides of the mounting plate 11, so that the first elongated pressing plate 241 presses the side end of the light source assembly. The second type is the mating pressing member 25, which is the same as the mating pressing member 25 described above. The mating pressing member 25 includes a second elongated pressing plate 250 extending downward from both ends of the pressing plate and two side wall slide rails 251 arranged opposite each other at the lower end. The second elongated pressing plate 250 has pressing grooves 248a at both ends to accommodate the end of the cover plate 22. The side wall slide rails 251 of the mating pressing member 25 are inserted into the slide groove 104, so that the second elongated pressing plate 250 presses the side end of the light source assembly. The difference between the end pressing member 24 and the mating pressing member 25 is that the end pressing member 24 has a pressing groove 248 at only one end to accommodate and press the end of the cover plate 22, while the mating pressing member 25 has pressing grooves 248a at both ends to accommodate and press the end of the cover plate.

[0029] It should be noted that a heat sink 1 is provided with at least two light source components, and each light source component has a mating crimping member 25 at at least one end. When three or more light source components are mated, both ends of the non-edge light source components are mating crimping members 25. Therefore, the specific structure of the mating crimping member 25 of the light source component is selected according to its location. Figure 8 This is a schematic diagram of the assembled light source module.

[0030] like Figure 9 As shown, the heat sink 1 includes a mounting plate 11 that is attached to the circuit board 21, two second heat transfer plates 102 and 102a extending from the lower surface of the mounting plate 11, and a third heat transfer plate 103 connecting the ends of the second heat transfer plates 102 and 102a. The heat sink 1 has an isosceles trapezoidal cross-section, with the second heat transfer plates 102 and 102a forming the two sides of the trapezoid, and the third heat transfer plate 103 forming the shorter side. The third heat transfer plate 103 has multiple heat dissipation grooves 131 milled on it, with a groove depth of 2 / 3 of the height of the second heat transfer plates 102 and 102a, and the grooves extending in a direction perpendicular to the plane of the mounting plate 11.

[0031] Mounting plate 11 (also the first heat transfer plate) serves as the plate directly supporting the sealed assembled light source module. Its overall planar design ensures the flatness of the light source contact surface. Second heat transfer plates 102 and 102a extend from both sides of mounting plate 11, forming the side walls of a quadrilateral flow channel. The ends are connected by the third heat transfer plate 103, ultimately forming the flow channel. The heat dissipation groove 131, through milling, forms multiple segments between the third heat transfer plate 103 and the second heat transfer plates 102 and 102a, creating localized thermal bridges perpendicular to the first heat transfer plate. This shortens the path of heat transfer from the first heat transfer plate to the third heat transfer plate, accelerating lateral heat diffusion. It increases the number of airflow channels while simultaneously reducing the overall weight of the heat sink. The axis of the heat dissipation groove 131 forms an angle of 60° to 90° with the plane of mounting plate 11, and the tangent axis is inclined or perpendicular to mounting plate 11, such as forming an angle of 85° ± 5°. Based on the fundamental principle of setting heat dissipation grooves to improve heat dissipation efficiency, the heat dissipation grooves can be set into various forms according to actual conditions, such as straight grooves, wavy grooves, or zigzag grooves, etc.

[0032] On the outer surface of the second heat transfer plates 102 and 102a, a plurality of strip-shaped heat dissipation fins 118 are arranged sequentially along the direction from the end near the mounting plate 11 to the end away from the mounting plate 11, parallel to the connecting edge of the second heat transfer plates 102 and 102a and the mounting plate 11; the third heat transfer plate 103 has a plurality of parallel heat dissipation fins 119, the second heat dissipation fins 119 being perpendicular to the heat dissipation groove 131, and the height of the strip-shaped heat dissipation fins 118 and the second heat dissipation fins 119 being 1 to 3 mm.

[0033] It should be noted that the thickness of the mounting plate 11 of the heat sink 1 is 3mm to 5mm; this thickness balances structural strength and thermal resistance control, shortens the heat conduction path by 40%, and ensures that heat is quickly transferred from the circuit board to the heat sink fins. The thickness T3 of the heat sink in the lower perforation area satisfies: T3 = T1 + (3mm to 5mm), to ensure that a pressure-bearing wall with a minimum thickness of ≥3mm is formed at the bottom of the lower perforation. This wall must simultaneously meet the dual requirements of sealing, pressure resistance, and processing rigidity.

[0034] The third heat transfer plate 103 is provided with a snap-fit ​​hole 132, and the head of the bird spike prevention mechanism 134 is elastically inserted and fixed to the snap-fit ​​hole 132. The bird spike prevention mechanism 134 is integrally bent from metal wire, which eliminates the need for welding or assembly, thus simplifying the production process.

[0035] refer to Figure 10 The bird spike protection mechanism 134 includes: The coiled torsion spring 51 is located in the middle; The first and second legs extend symmetrically outward from both ends of the coiled torsion spring 51 in opposite directions. The ends of each leg are folded back to form U-shaped snap-fit ​​portions 52 and 53. Strip-shaped bird spike portions 55 and 55a extend from the free ends of the U-shaped snap-fit ​​portions 52 and 53 toward the direction away from the center of the coiled torsion spring 51. The U-shaped snap-fit ​​parts 52 and 53 form a bidirectional axial snap-fit ​​engagement with the snap-fit ​​hole 132, and the strip-shaped bird-tooth parts 55 and 55a are distributed around the periphery of the third heat transfer plate. Here, "bidirectional axial snap-fit" refers to bidirectional fixation along the axial direction of the hole, achieving a bidirectional anti-detachment engagement between the U-shaped snap-fit ​​parts and the snap-fit ​​hole in the axial direction; that is, the snap-fit ​​parts cannot move along the axial direction of the hole after installation, ensuring stability. The coiled torsion spring 51 and the elastic metal wire provide continuous clamping force, ensuring long-term contact and connection with the snap-fit ​​hole in the installed state. In use, the U-shaped snap-fit ​​parts are simply snapped into the snap-fit ​​holes 40 and 40' respectively; this structure facilitates quick installation.

[0036] For a corresponding sealed cavity of a light source component, refer to Figure 6 The mounting plate 11 has a detection through-hole 77 that connects to the sealed cavity and penetrates the plate body. A sealing plug 78 is provided on the detection through-hole 77. In a specific example, the detection through-hole 77 is located on one side of the circuit board of the light source assembly at one end, and the side of the circuit board has a notch 79 corresponding to the detection through-hole 77; this facilitates operation. For a reasonable layout, a wiring notch 76 is provided on the edge of the circuit board of the other end of the light source assembly, and the mounting plate 11 body corresponding to the wiring notch 76 has a power connector mounting hole 75. The sealing plug 78 is made of silicone or rubber, and its structure includes a conical plug, a stepped cylindrical plug, a spiral plug, etc.; in a specific example... Figure 11-12The sealing rubber plug 78 is a rubber plug with external threads, which is pressed into the detection through hole 77 with interference fit. It has no auxiliary locking structure and is easy to operate.

[0037] The assembly method of the sealed assembly light source module of this utility model: S101, Light source assembly pre-installed Place the circuit board of one side of the light source assembly on the mounting plate of the heat sink, ensuring the annular sealing ring at the bottom of the circuit board fits against the mounting plate. Replace the cover plate, aligning its mounting groove with the second slide rail of the first slide member. Push the first slide member so that its first slide rail slides into the groove of the heat sink, and the second slide rail presses into the mounting groove, completing the long side fixation. The free end slides directly into the end pressing fitting, completing the short side fixation.

[0038] S102, Power cable installation Lead the power cord out from the terminal block of the light source assembly on that side, bend the wire and insert it into the wire hole on the corresponding side, and then pass it through the channel hole and out of the wire hole of the docking light source assembly before placing it into the temporary storage slot.

[0039] S203, sliding installation of butt-fitting crimp fittings Insert the mating crimping piece into the heat sink from the end and push it along the groove. When the mating crimping piece slides directly above the temporary storage slot, its bottom surface should cross the slot but not touch the wire. After the mating crimping piece has slid out of the temporary storage slot area, remove the wire.

[0040] S104. Installation of docking light source assembly Following the steps in S101, place the circuit board on the mounting plate of the heat sink. After closing the cover plate, press both sides onto the mounting plate using the first slider to complete the long side fixation. The free end is directly pressed in using the end pressing piece to complete the short side fixation.

[0041] The airtightness testing method for the sealed assembled light source module of this utility model can employ methods such as water immersion or air pressure attenuation, applying air pressure through the detection through-holes on the edge of the heat sink mounting plate. Details are as follows.

[0042] Test hole structure: The test through hole is opened on the back of the heat sink (non-light-emitting surface) and extends through to the sealed cavity of the light source.

[0043] The sealing plug is made of silicone or rubber with a Shore hardness of 40A to 60A. Structurally, it adopts an interference fit test hole, and its overall shape is a sealing plug body made of nut and threaded rod.

[0044] Test method: (1) Air pressure attenuation method: Seal all openings of the lamp (including the outlet) and inject compressed air (usually 5-10 kPa) through the test hole. Hold the pressure for 30 seconds; a pressure drop of ≤5% is considered acceptable.

[0045] (2) Water immersion method: The light fixture was submerged 10cm underwater. Inject air (pressure 3 kPa) into the test port air pipe; Locate the leak point by observing the location where the bubbles are generated.

[0046] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the device embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions of the method embodiments.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
