Description

Technical Field

[0001] This utility model belongs to the technical field of lighting devices, specifically relating to an anti-glare ring fixing structure and a lighting device. Background Technology

[0002] Currently, recessed or ceiling-mounted LED spotlights on the market often use a front ring (or anti-glare ring) to fix the optical components inside the lamp body, ensuring that the optical components accurately receive and emit light when the spotlight is working, thereby achieving the expected light emission effect.

[0003] In the fixing schemes between the front ring and the lamp body, the snap-fit ​​structure is widely used due to its ease of assembly and disassembly. However, for small spotlights, the engagement depth of the snaps is designed to be relatively small to meet the requirements of easy assembly and disassembly. In environments with large temperature differences, the front ring is prone to separating from the lamp body due to thermal expansion and contraction, causing optical components to fall out of the lamp body and creating a safety hazard in the area below the spotlight. This problem becomes even more pronounced after repeated assembly and disassembly of the front ring due to component aging.

[0004] Currently, common improvement methods include replacing the snap-fit ​​connection with a threaded connection, or adding a face shield to the front of the front ring to prevent the front ring from falling and thus avoiding safety risks. However, both of these methods make the overall structure of the spotlight more complex, increase the production difficulty of small spotlights, and reduce assembly efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-glare ring fixing structure and lighting device. The anti-glare ring is connected to the lamp body's slot via a snap-fit ​​mechanism, and the fastener's end passes through a through-hole for double locking and securing. This ensures a stable and secure connection between the anti-glare ring and the lamp body even under conditions of significant temperature differences or aging, preventing the safety risks caused by the anti-glare ring detaching. Furthermore, compared to existing threaded connections, its installation efficiency is higher.

[0006] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0007] In a first aspect, this utility model provides an anti-glare ring fixing structure, comprising:

[0008] An anti-glare ring includes a substrate and an outer shell and an inner shell disposed on the substrate. The substrate has a light-emitting port, and the outer shell has a locking block and a through hole.

[0017] In some implementations, the via is radially formed on the outer casing, and a first protrusion is provided on the upper edge of the outer casing, with the first protrusion positioned above the via;

[0018] Using the plane containing the top edge of the outer shell as the base plane, the projection of the first protrusion on the base plane covers the projection of the through hole on the base plane.

[0019] In some implementations, the upper edge of the outer shell is further provided with a second protrusion, and the second protrusion has a positioning groove;

[0020] The mounting part is also provided with a positioning post on the inner side wall. The positioning post is inserted into the positioning groove and is used to guide the anti-glare ring to be installed in the lamp body.

[0022] The cover is disposed on the outer periphery of the lamp body, the cover has a through hole, the fastener passes through the through hole and is fixedly connected to the insertion hole, and the end of the fastener extends into the through hole;

[0023] The light source assembly and the lens are installed in the receiving cavity. The light emitted by the light source assembly passes through the lens and is emitted to the outside from the light outlet.

[0024] In some implementations, the anti-glare ring further includes positioning ribs that extend radially from the outer side of the inner housing to the outer housing, and the positioning ribs form a limiting ring around which the light-emitting end of the lens is located.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0051] Example 1:

[0052] Please see Figures 1-5 This embodiment provides an anti-glare ring fixing structure 100, including an anti-glare ring 1, a lamp body 2, and fasteners 3. This anti-glare fixing structure 100 is applied to lighting devices such as spotlights, downlights, or ceiling lights; it is also suitable for small lighting fixtures.

[0053] Specifically, the anti-glare ring 1 includes a substrate 11 and an outer shell 12 and an inner shell 13 disposed on the substrate 11. The substrate 11 has a light outlet 111, and the outer shell 12 has a locking block 121 and a through hole 122. The locking block 121 extends from the top edge of the outer shell 12 in a direction away from the light outlet 111. The lamp body 2 includes a heat dissipation part 21 and a mounting part 22. The mounting part 22 and the heat dissipation part 21 surround to form a receiving cavity 23. The receiving cavity 23 has an opening 231. The mounting part 22 has a slot 221 and a socket 222 on its inner sidewall. The locking block 121 is snapped into the slot 221. The fastener 3 is locked into the socket 222, and the end of the fastener 3 passes through the through hole 122. The anti-glare ring 1 is disposed at the opening 231.

[0054] In the specific installation process, first align the positions of the through hole 122 and the socket 222, and connect the fastener 3 into the socket 222; then push one side of the outer shell 12 into the opening 231, and the end of the locking block 121 formed on the outer shell 12 abuts against the inner wall of the mounting part 22 and deforms and bends towards the receiving cavity 23; continue to push the anti-glare ring 1 towards the opening 231 until the base plate 11 abuts against the edge of the mounting part 22, and at the same time, the locking block 121 also reaches the position of the slot 221 and is snapped into the slot 221, thus completing the first connection and fixation. At the same time as the first connection and fixation is completed, the through hole 122 is also basically aligned with the socket 222. At this time, continue to move the fastener 3 that has been connected in the socket 222, so that the end of the fastener 3 passes through the through hole 122, completing the second locking and fixation, and realizing the fixed connection between the anti-glare ring 1 and the lamp body 2.

[0055] During production, the anti-glare ring 1 and the lamp body 2 undergo different thermal deformations at different locations due to differences in materials, structural characteristics, and heating conditions. This results in varying degrees of thermal expansion and contraction between the locking block 121 on the outer casing 12 and the locking groove 221 on the mounting part 22. For some lighting devices, especially small spotlights, downlights, and ceiling lights, the engagement amount between the locking block 121 and the locking groove 221 is small, making them prone to disengagement under thermal expansion and contraction. In this case, the end of the fastener 3 passes through the through hole 122, effectively preventing the anti-glare ring 1 from detaching from the lamp body 2 and ensuring the safety of personnel below.

[0056] With the anti-glare ring 1 and lamp body 2 securely connected, during installation, the locking block 121 quickly engages with the locking slot 221, allowing the end of the fastener 3 to move into the through hole 122. This simple and quick operation offers higher installation efficiency compared to existing threaded connections. In this embodiment, the fastener 3 is a screw, and the insertion hole 222 has threads matching the screw. Only 1-3 turns of rotation are needed to allow its end to enter the through hole 122. In other embodiments, the fastener 3 can also employ a spring-loaded mechanism. By pressing the outer side of the fastener 3, the end of the fastener 3 can be moved into or out of the through hole 122, completing the setting and release of the second locking mechanism.

[0057] In some embodiments, the outer shell 12 has an annular structure, and the inner shell 13 has a conical structure. One end of the inner shell 13 is connected to the outer shell 12 at the light exit port 111, and the other end has a light entrance port 131. The outer surface of the outer shell 12 abuts or is adjacent to the inner sidewall of the mounting portion 22, facilitating guidance during the installation of the anti-glare ring 1. The end of the conical inner shell 13 generally abuts against the optical lens. After being processed by the optical lens, the light from the light source assembly enters the anti-glare ring 1 through the light entrance port 131 and then exits through the light exit port 111. In other embodiments, an optical processing structure, such as a reflective coating or a scattering coating, is provided on the inner sidewall of the inner shell 13. The light from the light entrance port 131 can achieve more light emission effects through the optical processing structure.

[0058] like Figures 3-5 As shown, the anti-glare ring 1 further includes a first rib 14 and a second rib 15, with the second rib 15 positioned on both sides of the first rib 14. One end of the first rib 14 and the second rib 15 are respectively connected to the inner shell 13, and the other end is respectively connected to the locking block 121. With the first rib 14 and the second rib 15 provided, when the locking block 121 is connected to the locking slot 221, the locking block 121's resistance to deformation by external force is improved, making it less likely for the locking block 121 and the locking slot 221 to be easily pulled apart by external force. At the same time, it improves the locking block 121's resistance to deformation during thermal expansion and contraction, achieving a wider temperature difference adaptation range.

[0059] In a further embodiment, the first rib 14 extends radially from the outer side of the inner housing 13 to the locking block 121, connecting the inner housing 13 and the locking block 121, strengthening the load-bearing capacity of the locking block 121 during deformation, and improving the firmness of the connection between the locking block 121 and the locking groove 221. To make the stress distribution on the locking block 121 more reasonable with respect to the first rib 14 and the second rib 15, and to facilitate demolding during production, the second rib 15 and the first rib 14 have an included angle α, where 10°≤α≤20°. When the locking block 121 is subjected to bending force, the first rib 14 bears a larger radial force, while the second rib 15 bears an asymmetrical off-center load from both sides of the locking block 121. This asymmetrical off-center load originates from the misalignment of the shaft core of the lamp body 2 and the shaft core of the anti-glare ring 1 during installation. When the included angle α is less than 10°, the second rib 15 has poor resistance to deformation, and the two sides of the end of the locking block 121 are prone to deformation, making it difficult to align the anti-glare ring 1 with the shaft of the mounting part 22. When multiple locking blocks 121 are provided, some locking blocks 121 may fail to snap into the slot 221, resulting in a loose connection and reducing the firmness of the first connection. When the included angle α is greater than 20°, the structure of the second rib 15 and the locking block 121 is too strong, making the installation of the anti-glare ring 1 more difficult, and the locking block 121 is not easy to snap into the slot 221. Only when the included angle α meets the condition of 10°≤α≤20° can the locking block 121 be in a more ideal state, and the anti-glare ring 1 can accurately and conveniently complete the first fixed connection with the lamp body 2.

[0060] In this embodiment, to reduce the impact of the deformation of the locking block 121 on the lifespan of the outer shell 12, the outer shell 12 is provided with deformation grooves 123, which are located on both sides of the locking block 121. The deformation grooves 123 effectively separate the deformation of the locking block 121 from other parts of the outer shell 12, reducing the impact of elastic deformation on other parts of the outer shell 12, reducing the aging rate of the outer shell 12, and improving the service life of the anti-glare ring 1. The slot 221 is a ring-shaped groove formed on the inner sidewall of the mounting part 22, and the locking block 121 does not need to be aligned with the slot 221 to complete the snap-fit ​​connection. This also allows the same lamp body 2 to accommodate anti-glare rings 1 with different numbers of locking blocks 121, reducing the cost of use.

[0061] Continue reading Figures 1-5 The through-hole 122 has an elliptical, near-elliptical, or racetrack-shaped structure, and the end of the fastener 3 does not abut against the housing 12. This through-hole shape effectively prevents the end of the fastener 3 from failing to enter the through-hole 122 due to machining errors, ensuring effective installation. The fact that the end of the fastener 3 does not abut against the housing 12 reduces wear between the fastener 3 and the housing 12, increasing the service life of both the anti-glare ring 1 and the fastener 3.

[0062] In a further embodiment, a through hole 122 is radially formed on the outer casing 12, and a first protrusion 124 is provided on the upper edge of the outer casing 12, with the first protrusion 124 positioned above the through hole 122. Taking the plane containing the top edge of the outer casing 12 as the base plane, the projection of the first protrusion 124 on the base plane covers the projection of the through hole 122 on the base plane. The radially formed through hole 122 facilitates molding in the mold onto the outer casing 12, simplifying the production process of the anti-glare ring 1. The first protrusion 124 strengthens the connection portion at the upper end of the through hole 122. When the anti-glare ring 1 is subjected to external force causing the locking block 121 to slip off from the locking groove 221, the first protrusion 124 can effectively withstand the force from the fastener 3, ensuring the effectiveness of the second locking fixation between the fastener 3 and the through hole 122.

[0063] In this embodiment, a second protrusion 125 is provided on the upper edge of the outer casing 12, and the second protrusion 125 has a positioning groove 1251. Correspondingly, the mounting part 22 also has a positioning post 223 on its inner sidewall, which is inserted into the positioning groove 1251 to guide the anti-glare ring 1 to be installed in the lamp body 2. The cooperation between the positioning post 223 and the positioning groove 1251 makes the installation of the anti-glare ring 1 and the lamp body 2 more convenient, and the through hole 122 and the insertion hole 222 do not need to be manually aligned, achieving the effect of structural error prevention. In addition, under the guidance of the positioning groove 1251, the concentricity of the installation of the anti-glare ring 1 and the lamp body 2 is higher, and the synchronization of the snap-fit ​​connection between the multiple locking blocks 121 and the locking groove 221 is better, avoiding the situation where individual locking blocks 121 and locking grooves 221 are not properly connected.

[0064] In summary, the anti-glare ring fixing structure provided in this embodiment achieves the first layer of connection and fixing through the snap-fit ​​connection between the clip and the slot, and then completes the second layer of locking and fixing by passing the end of the fastener through the through hole. Even when encountering large temperature differences, aging, or other conditions, the double locking structure can ensure that the connection between the anti-glare ring and the lamp body is stable and firm, avoiding the safety risks caused by the anti-glare ring falling off.

[0065] In addition, the provided anti-glare ring fixing structure, while ensuring stable and reliable connection, has higher installation efficiency compared to the existing threaded connection method.

[0066] Example 2:

[0067] Please Figures 1-5 Based on the above, refer to Figures 6-7 This embodiment provides a lighting device 200, which is a small or medium-sized lamp such as a spotlight, downlight, or ceiling light, especially a small LED lamp; the anti-glare fixing structure 100 is also applicable to small lamps, which includes a light source assembly 4, a lens 5, and a cover 6, as well as the anti-glare ring fixing structure 100 provided in Embodiment 1.

[0068] Specifically, the cover 6 is located on the outer periphery of the lamp body 2, and the cover 6 has a through hole 61. The fastener 3 passes through the through hole 61 and is fixedly connected to the insertion hole 222, while the end of the fastener 3 extends into the through hole 122. The cover 6 is the part that connects the lighting device 200 to the external structure. The fastener 3 fixes the cover 6 to the lamp body 2 through the through hole 61, and at the same time provides a second locking fixation for the anti-glare ring 1, making the installation simpler and reducing the number of parts.

[0069] More specifically, the light source assembly 4 and the lens 5 are installed in the receiving cavity 23. The light emitted by the light source assembly 4 passes through the lens 5 and exits to the outside through the light outlet 111. In actual production, the light source assembly 4 is fixed to the heat dissipation part 21 on the side facing the receiving cavity 23, with its light-emitting side facing the opening 231. The lens 5 generally includes an input end 51 and an output end 52. The input end 51 abuts against the light source assembly 4 and receives the light emitted by the light source assembly 4 into the input end 51. After optical processing by the lens 5, the light is then emitted through the output end 52, which faces the opening 231.

[0070] By employing the anti-glare ring fixing structure 100, compared to existing methods that use external parts such as face shields to abut and fix the anti-glare ring 1, the lighting device 200 provided in this embodiment has fewer parts and lower production costs. Compared to existing lighting devices with snap-fit ​​connections, the connection between its anti-glare ring 1 and lamp body 2 is more stable and reliable. Furthermore, for existing lighting devices using threaded anti-glare ring connections, installation is more convenient, maintenance costs are lower, and service life is longer.

[0071] In a further embodiment, the anti-glare ring 1 also includes a positioning rib 16, which extends radially from the outer side of the inner housing 13 to the outer housing 12. The positioning rib 16 forms a limiting ring 161 around the lens 5, and the light-emitting end 52 of the lens 5 is located in the limiting ring 161. With the positioning rib 16, the overall structure of the anti-glare ring 1 is more robust, allowing for further reduction in the thickness of the inner housing 13 and the outer housing 12, thus reducing the weight and material usage of the anti-glare ring 1. Secondly, the limiting ring 161 formed by the positioning rib 16 can be positioned before the lens 5 is installed into the receiving cavity 23. Then, through the installation of the anti-glare ring 1 and the mounting part 22, the positional accuracy of the lens 5 and the light source assembly 4 is ensured, achieving the optical design effect in the lighting device 200.

[0072] In summary, the lighting device provided in this embodiment adopts an anti-glare ring fixing structure with a double locking structure. Compared with the existing anti-glare ring fixing method, the anti-glare ring is more securely fixed to the lamp body, while having fewer parts, lower production and maintenance costs, and a longer service life.

[0073] Example 3:

[0074] Please Figures 1-7 Based on the above, refer to Figure 8 This embodiment provides a lighting device 200, which is an adjustment and optimization based on the lighting device 200 provided in Embodiment 2. The difference between the lighting device 200 in this embodiment and that in Embodiment 2 is that the cover 6 includes a panel portion 62 and a ring portion 63. The panel portion 62 has a ring-shaped plate structure and abuts against the edge of the mounting portion 22. The ring portion 63 is disposed around the outside of the mounting portion 22, and one end of it is connected to the panel portion 62. A through hole 61 is provided on the ring portion 63, and a fastener 3 is inserted into the through hole 61 through the outside of the ring portion 63, thereby being fixedly connected to the insertion hole 222.

[0075] Furthermore, the cover 6 also includes a mounting member 64, which is elastically connected to the other end of the ring portion 63. Through the mounting member 64, the lighting device 200 can be quickly fastened to an external mounting structure in a fixed position, reducing the difficulty of installing the lighting device 200 in a fixed position. To improve the assembly efficiency of the lighting device 200, the mounting member 64 is positioned around the through hole 61.

[0076] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
