Description

Technical Field

[0001] This utility model relates to the field of LED lighting module technology, specifically a potable lighting module for lighting fixtures. Background Technology

[0002] In industrial workshops, LED light-emitting modules need to cope with complex environments with high dust, oil, mechanical vibration, and high lighting intensity requirements for extended periods. Existing technologies have particularly prominent shortcomings in this scenario, resulting in a series of interconnected problems.

[0003] Industrial workshops have high requirements for lighting brightness and precision. Processes such as precision assembly and parts quality inspection rely on stable, high-efficiency lighting. However, the adhesives used in existing light-emitting modules are incompatible with the refractive indices of the LED lens encapsulation materials and lampshades. This leads to significant light loss during transmission due to differences in the medium, and insufficient luminous efficacy directly affects the uniformity of brightness in the work area, increasing the risk of visual errors in precision operations. Simultaneously, oil and metal dust in the workshop can easily penetrate the module's interior through sealed gaps. The existing sealing structure design is inadequate and cannot effectively isolate these contaminants, causing oil and dust to adhere to the LED surface. This exacerbates luminous efficacy decay, leads to poor heat dissipation, and can even cause short circuits. Frequent module replacements not only increase production costs but may also disrupt the production process.

[0004] Problems with cleaning and maintenance further amplify the aforementioned deficiencies. Oil and dust in the workshop are highly adhesive, and the existing modules' adhesive layers or lampshade surfaces lack durable protective structures, making them easily scratched by handling tools. Furthermore, once the oil solidifies, it is difficult to remove with conventional wiping. High-pressure cleaning or using hard tools exacerbates the damage to the adhesive layer, creating a vicious cycle of "the more frequent the cleaning, the faster the light transmittance decreases." Long-term use results in a significant decrease in lighting performance, impacting production efficiency. In addition, irregular overflow of sealant during assembly and the lack of effective shielding structures lead to a rough module appearance and poor coordination with the precision equipment in the workshop. An unreasonable fixing structure design exacerbates this problem—mechanical vibrations in the workshop cause the pre-fixation and final fixing effects of the components to fail. The sealing gaps continue to widen due to vibration, increasing the area of ​​sealant overflow and indirectly exacerbating light efficiency loss due to component misalignment altering the light transmission path, creating a chain reaction of problems. Utility Model Content

[0005] The purpose of this invention is to provide a potable lamp light-emitting module to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a potable lamp light-emitting module, including a heat sink, a light strip fixedly disposed on the heat sink, LED beads fixedly disposed on the light strip, a lamp cover disposed on the light strip, the lamp cover being connected to the heat sink and forming an accommodating cavity, and the light strip being located within the accommodating cavity;

[0007] In this invention, the accommodating cavity provides a closed protective space for the light strip, reducing the direct corrosion of the light strip and LED beads by external environmental factors such as dust and moisture; the structure of the lamp cover and heat sink encloses the module as a compact protective unit, providing a foundation for subsequent potting and sealing component installation, and improving the integration of the module.

[0008] A sealing component is provided at the gap between the lamp cover and the lamp strip, and a covering component is provided at the end of the heat sink assembled with the lamp cover, the covering component covering the sealing component;

[0009] In this invention, the sealing component specifically fills the gap between the lampshade and the lamp strip, blocking the path of moisture and dust to enter through the gap and improving the sealing and protection capability of the module; the covering component forms a physical shield for the sealing component, which not only prevents the sealing component from being directly exposed to external force damage, but also hides the connection marks and improves the cleanliness of the module's appearance.

[0010] Both ends of the radiator are connected to fixing components, which pass through the covering component and the sealing component and are connected to the radiator; structural adhesive is provided at the connection between the lampshade and the radiator.

[0011] In this invention, the fixing component is fixed through both ends, so that the covering component, the sealing component and the heat sink form a rigid connection, which avoids the sealing failure caused by the loosening of the components and enhances the overall structural stability; the structural adhesive forms an adhesive seal at the connection between the lamp cover and the heat sink, forming "double protection" with the mechanical fixation of the fixing component, further improving the waterproof level and connection strength of the module.

[0012] The cavity is filled with potting compound, the refractive index of which is compatible with the encapsulation material of the LED beads and the refractive index of the lamp cover.

[0013] In this invention, the potting compound fills the cavity, forming a full-coverage of the light strip and LED beads, achieving "overall sealing" and significantly improving waterproof and dustproof performance; its refractive index is compatible with the LED bead encapsulation material and lampshade, reducing refraction loss of light when it is transmitted between different media, significantly improving luminous efficiency and ensuring lighting brightness.

[0014] Preferably, the lampshade has buckles on both sides, and the heat sink has grooves on both sides that are adapted to the buckles. The structural adhesive is filled in the grooves, and the two buckles are respectively fastened into the grooves at their corresponding positions.

[0015] In this invention, the mechanical cooperation between the buckle and the groove enables the lampshade and the heat sink to be quickly positioned and installed, ensuring assembly accuracy; the structural adhesive fills the groove and combines with the buckle, so that the two form a composite connection of "mechanical fixation + adhesive bonding", which not only prevents the buckle from loosening, but also further enhances the sealing performance by filling the groove gaps with adhesive, preventing moisture from entering from the side.

[0016] Preferably, the sealing component is a silicone plug, which includes a deformable sealing portion that deforms under the pressure of the fixing component.

[0017] In this invention, the silicone material has excellent elasticity and aging resistance, making it suitable for long-term sealing use; the sealing part deforms under the pressure of the fixed component, which can adaptively fill the gap between the lamp cover and the lamp strip. Even if there is a slight dimensional deviation in the gap, it can achieve "interference sealing", effectively blocking the moisture path and improving the sealing reliability of the module, especially suitable for harsh environments such as outdoor and humid environments.

[0018] Preferably, the covering component is an awning, which has an eave that covers the end of the lampshade.

[0019] In this utility model, the eaves of the cover wrap around the end of the lampshade, which can not only restrict the axial displacement of the lampshade and help fix the lampshade, but also block external dust and water droplets from directly impacting the end gaps, thus enhancing end protection; at the same time, the cover covers the exposed parts of the sealing and fixing components, preventing the components from being directly exposed and affecting the aesthetics, thus improving the appearance quality of the module.

[0020] Preferably, the fixing component includes an iron sheet and a connector. The iron sheet is provided with an injection channel, and the connector passes through the iron sheet, the covering component, and the sealing component in sequence before connecting to the heat sink. The iron sheet can be removed after the potting compound has cured.

[0021] In this invention, the injection channel provides a channel for injecting potting compound into the accommodating cavity, ensuring that the potting compound can fully fill the cavity and avoid air bubbles or unfilled areas affecting the sealing and light effect; the through-fixed connector ensures that all components fit tightly and prevents assembly gaps; the detachable iron sheet design avoids long-term exposure that affects the appearance or increases cleaning difficulty, while reducing material costs and improving the practicality of the module.

[0022] Preferably, the lampshade includes a light-transmitting section located in the middle and light-shielding sections located on both sides.

[0023] In this invention, the central light-transmitting section ensures efficient light transmission from the LED beads to meet lighting needs; the two side light-shielding sections can cover appearance defects such as overflowing structural adhesive and snap-fit ​​connection marks. It can achieve both lighting function and aesthetics without additional decorative parts, simplifying structural design and reducing production costs.

[0024] Preferably, the light strip is fixed to the heat sink by thermally conductive adhesive, the heat sink has a groove, the light strip includes a light plate, the LED beads are fixedly connected to the light plate, and the edge of the light plate is placed in the groove.

[0025] In this invention, the thermally conductive adhesive improves the heat conduction efficiency between the lamp board and the heat sink, quickly conducting the heat generated by the LED beads during operation to the heat sink for dissipation, preventing the beads from decaying or being damaged due to overheating, and extending their service life; the groove's limiting effect on the edge of the lamp board prevents the light strip from shifting during installation, ensuring the relative positional accuracy of the light strip and the lamp cover, reducing gaps, and helping to improve sealing performance.

[0026] Preferably, the potting compound is a transparent gel, and the outer surface of the lampshade is a hard, smooth surface. The lampshade is made of PC material.

[0027] In this invention, the transparent gel potting compound does not block light, ensuring high light transmittance of LED light. At the same time, its gel state has a certain degree of elasticity, which can buffer the impact of external vibration on the light strip. The hard and smooth design of the outer surface of the lampshade makes it scratch-resistant and wear-resistant, and dust and stains do not easily adhere to it. It is easy to clean by means of high-pressure water guns, etc., and maintains light transmittance for a long time, reducing maintenance costs. It is especially suitable for dusty environments such as outdoor and industrial workshops.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] In this invention, the refractive index of the potting compound is compatible with the refractive index of the LED chip encapsulation material and the lamp cover, which can expel the air between the chip and the lamp cover, allowing light to be transmitted in a medium with a similar refractive index, minimizing refraction loss and significantly improving luminous efficiency; at the same time, the light-transmitting section in the middle of the lamp cover ensures efficient light transmission, ensuring the brightness uniformity required for precision assembly and parts quality inspection in industrial workshops, and reducing the risk of visual errors in precision operations.

[0030] In this invention, structural adhesive fills the gap between the lampshade clip and the heat sink groove to form a side seal. The sealing part of the silicone plug deforms under the pressure of the fixing component to fill the end gap. The potting compound fills the accommodating cavity to achieve overall encapsulation. The three-level sealing structure works together to effectively block the intrusion of workshop oil and metal dust and prevent contaminants from adhering to the surface of the lamp beads. At the same time, the lamp strip is fixed to the heat sink by thermally conductive adhesive. With the limiting of the groove, the heat dissipation efficiency is ensured to be stable, reducing circuit short circuits caused by poor heat dissipation, reducing the frequency of module replacement, and avoiding production process interruption.

[0031] In this invention, the lampshade is made of PC material with a hard, smooth outer surface that is scratch-resistant, wear-resistant, and resistant to oil and dust adhesion. The potting compound is injected inside the cavity to prevent direct exposure and damage. This design allows the module to be easily cleaned by high-pressure water jet washing or wiping, and the light transmittance remains stable after long-term use, completely breaking the vicious cycle of "the more frequent the cleaning, the faster the light transmittance decreases," thus reducing maintenance costs. In this invention, the light-shielding sections on both sides of the lampshade can block appearance defects caused by structural adhesive overflow, allowing it to be coordinated with precision equipment in the workshop without additional decorative parts. At the same time, the mechanical cooperation of the buckle and groove, the through-fixation of the fixing components, and the elastic deformation of the silicone plug and potting compound can effectively resist mechanical vibration in the workshop, preventing component displacement from causing the sealing gap to widen. This reduces the extent of adhesive overflow and prevents changes in the light transmission path due to component displacement, thus mitigating light efficiency loss at its source.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] Please refer to Figures 1-5. A potting-compatible lighting module includes a heat sink 1, a light strip 2, a lamp cover 3, a sealing component 4, a covering component 5, a fixing component, structural adhesive 8, and potting compound 9. The specific assembly steps are as follows:

[0040] Furthermore, the fixing of the light strip to the heat sink: The heat sink 1 is pre-fixed to the lighting bracket in the industrial workshop, and the heat sink 1 is rigidly connected to the bracket with bolts to ensure that it does not shift in the mechanical vibration environment. Align the edge of the light plate 21 of the light strip 2 with the groove 13 of the heat sink 1, and apply thermally conductive adhesive (not shown) evenly to the back of the light plate 21 so that the light plate 21 adheres to the surface of the heat sink 1.

[0041] The groove 13 forms a mechanical limit on the lamp board 21, achieving pre-fixation before the thermally conductive adhesive cures, thus preventing the lamp strip 2 from shifting due to workshop vibration. After the thermally conductive adhesive cures, it not only enhances the heat dissipation efficiency of the LED beads 22, which requires efficient heat dissipation during long-term high-power operation in industrial workshops, but also forms a secondary fixation.

[0042] Furthermore, the sealing connection between the lampshade and the heat sink is as follows: Structural adhesive 8 is filled into the grooves 11 on both sides of the heat sink 1. The structural adhesive is an oil-resistant silicone sealant suitable for the oily environment of the workshop. The clips 31 on both sides of the lampshade 3 are aligned with the grooves 11, and pressure is applied to make the clips 31 fully engage with the grooves 11 and embed them into the structural adhesive 8. Let it stand for 24 hours to allow the structural adhesive to cure.

[0043] The mechanical cooperation between the buckle 31 and the groove 11 resists vibration and impact. The structural adhesive 8 fills the gaps and forms a "rigid fixation + flexible sealing" composite structure with the buckle, preventing metal dust and oil stains in the workshop from entering through the side gaps.

[0044] It should be noted that structural adhesive 8 is filled in the grooves 11 on both sides of the radiator 1. The structural adhesive is an oil-resistant silicone adhesive, which is suitable for the oily environment of the workshop. The specific indicators are: no swelling after soaking in 30# machine oil for 72 hours, and stable performance after soaking in 5% emulsified cutting fluid for 72 hours.

[0045] Further, the end sealing and covering assembly is installed: Insert the silicone plug of the sealing component 4 into the end gap between the lampshade 3 and the light strip 2, ensuring that the sealing part 41 of the silicone plug is completely fitted into the gap. Slide the cover of the covering component 5 onto the end of the module, so that it completely covers the silicone plug, and the rim of the cover wraps around the end edge of the lampshade 3.

[0046] The elastic material of the silicone plug can absorb vibration energy and prevent sealing failure caused by hard impacts; the rim of the cover prevents handling tools from scratching the silicone plug, and at the same time prevents oil stains splashed in the workshop from directly adhering to the sealing part.

[0047] Further, the installation and preparation of the fixing components: Attach the metal plate 6 of the fixing components to the outer surface of the cover, aligning the glue injection channel 61 of the metal plate 6 with the first connecting hole 51 of the cover. Use the connecting screw 7 to sequentially pass through the third connecting hole 62 of the metal plate 6, the second connecting hole 52 of the cover, and the hole 42 of the silicone plug, finally screwing it into the fourth connecting hole 12 of the radiator 1, tightening it until the sealing part 41 of the silicone plug undergoes significant deformation with a compression amount of approximately 0.5–1 mm.

[0048] The rigid fixation of screw 7 ensures that all components fit tightly under vibration, and the deformation of the silicone plug achieves "interference seal" to prevent water from entering from the end during high-pressure cleaning; the iron plate 6 temporarily presses the silicone plug to provide a stable sealing environment for the glue dispensing stage.

[0049] Further, potting and curing of the potting compound: Insert the needle of the dispensing machine into the silicone plug through the dispensing channel 61 of the iron sheet 6, and pour the potting compound 9 into the cavity enclosed by the lamp cover 3 and the lamp strip 2 until the cavity is completely filled. Observe the filling status through the light-transmitting section 33 of the lamp cover 3. After potting, let it stand for 48 hours to allow the potting compound 9 to fully cure.

[0050] The refractive index of potting compound 9 (1.52-1.58) matches the silicone material of the LED bead 22's encapsulation lens (1.53) and the 3PC material of the lamp cover (1.58), reducing light refraction loss required for precision operations in the workshop; the gel state can buffer the impact of vibration on the LED bead, while isolating it from air and oil.

[0051] When the LED bead 22 is encapsulated with silicone (refractive index approximately 1.53) and the lampshade 3 is made of PC (refractive index approximately 1.58), the potting compound 9 can be a transparent silicone rubber potting compound, model Dow Corning 3-4248, with a refractive index of 1.54. The difference between its refractive index and the two is ≤0.05, which can effectively reduce light refraction loss. When the lampshade 3 is made of PMMA (refractive index approximately 1.49), a transparent polyurethane potting compound, model Henkel Loctite 9460, with a refractive index of 1.50, can be used. The compatibility also meets the high luminous efficiency requirements of industrial workshops.

[0052] Further post-processing and lamp assembly: After the potting compound 9 has cured, remove screws 7 and take off the metal plate 6, leaving the end cover for protection. Connect the module to the workshop power supply line to complete the integration with the workshop lighting system.

[0053] After the iron sheet 6 is removed, the exposed parts are reduced, and the risk of oil stains is lowered. The hard and smooth outer surface of the lampshade 3 can be directly washed with a high-pressure water gun, which is suitable for the regular cleaning needs of the workshop. The light-shielding section 34 blocks the excess adhesive residue of the structural adhesive 8, maintaining the appearance coordination with the workshop equipment.

[0054] Example 2

[0055] Implementation methods for enhanced sealing under strong vibration environments:

[0056] For areas with high vibration such as stamping and forging in the workshop, the following optimizations are added based on Example 1:

[0057] A rubber buffer pad is added inside the groove 13 of the radiator 1 to further absorb the vibration energy of the light strip 2;

[0058] The sealing part 41 of the silicone plug adopts a honeycomb structure design to improve deformation compensation capability and ensure that it always fits the gap during vibration.

[0059] The potting compound 9 uses the high-elasticity formula Shore A with a hardness of 60±5, which enhances the shockproof protection of the LED 22.

[0060] Working principle

[0061] The module assembly begins with component assembly. First, the light plate 21 of the light strip 2 is fixed to the heat sink 1 using thermally conductive adhesive, with the edge of the light plate embedded in the groove 13 of the heat sink. Before the thermally conductive adhesive cures, the groove 13 provides mechanical restraint for the light strip, preventing it from shifting due to workshop vibrations. The thermally conductive adhesive simultaneously achieves the dual functions of "fixing + heat dissipation," firmly securing the light strip while conducting the heat generated by the LED beads 22 during operation to the heat sink for dissipation, thus meeting the requirements of long-term high-power operation of LED beads in industrial workshops.

[0062] The lampshade 3 is fastened to the groove 11 of the heat sink 1 via clips 31 on both sides. The structural adhesive 8 pre-filled in the groove is squeezed by the clips, which not only strengthens the connection between the lampshade and the heat sink through adhesive bonding, but also fills the gap between the two to form a side seal, preventing metal dust and oil stains in the workshop from entering from the side. The lampshade adopts a two-color extrusion process. The light-transmitting section 33 in the middle ensures that light can pass through, while the light-shielding sections 34 on both sides cover the appearance defects caused by excess structural adhesive. It can meet the appearance coordination requirements of precision equipment in the workshop without additional decoration.

[0063] The gap between the lampshade and the end of the light strip is filled by a sealing component 4, namely a silicone plug. The sealing part 41 of the silicone plug has deformable characteristics. After the cover is inserted into the end, it is connected to the heat sink 1 through the cover and the silicone plug by a fixing component. At this time, the silicone plug is squeezed by the iron sheet and the heat sink, and the sealing part 41 deforms and tightly fits the gap to form an end seal. The rim of the cover wraps around the end of the lampshade, which not only prevents the silicone plug from being scratched by handling tools, but also prevents oil stains splashed in the workshop from directly impacting the sealing part, further strengthening the protection.

[0064] Encapsulating adhesive 9, i.e., AB transparent gel, is injected into the cavity enclosed by the lamp cover 3 and the lamp strip 2 through the injection channel 61 of the iron sheet 6 until the cavity is full. The refractive index of the encapsulating adhesive matches the encapsulation material of the LED bead 22 and the refractive index of the lamp cover 3, which can eliminate air between the bead and the lamp cover, allowing light to be transmitted in a medium with a similar refractive index, reducing refraction loss and improving luminous efficiency. After the encapsulating adhesive cures, it forms an integral seal, completely encapsulating the lamp strip. Combined with side and end seals, the module achieves an IP66 waterproof and dustproof rating, making it suitable for dusty and oily workshop environments. After the encapsulating adhesive cures, the iron sheet 6 can be removed, avoiding long-term exposure and increased cleaning difficulty.

[0065] After the module is connected to the power supply, the light emitted by the LED beads 22 is emitted through the potting compound and the light-transmitting section 33 of the lamp cover, meeting the high light efficiency requirements of precision assembly, quality inspection and other processes in the workshop. During operation, the mechanical fixing of the groove 13 and buckle 31 of the heat sink 1 with the connector 7, combined with the elastic deformation of the silicone plug and potting compound 9, can absorb the vibration energy of the workshop and prevent the parts from loosening and causing the seal to fail.

[0066] During maintenance, the hard, smooth outer surface of lamp cover 3 facilitates high-pressure water washing or wiping, easily removing attached oil and dust, thus solving the problem of existing modules being "difficult to clean and having lower light transmittance the more they are cleaned." After power is turned off, the potting compound still encapsulates the LED beads, and the structural adhesive and silicone plug maintain a sealed state, ensuring that contaminants cannot enter during standby and that performance remains stable upon the next startup.

[0067] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
