Description

TECHNICAL FIELD

[0001] The utility model relates to lighting equipment technical field especially, relates to a lens fixing device and lighting equipment. BACKGROUND

[0002] In the existing lighting equipment design, many products adopt buckle structure to realize the fixed when installing the lens. This buckle structure is quite widely used on large lighting equipment, and because its structure is stable, installation is simple and is favored. However, this buckle fixing mode has a significant limitation, that is, it is mainly applicable to the lighting equipment type of large size and having enough installation space.

[0003] When it is related to the strong portability, the size of small lighting equipment, the situation is quite different. This kind of small lighting equipment is often due to the compact size, and the installation space of lens is extremely small, so that the traditional buckle structure is difficult to play. Therefore, when fixing and installing the lens of this kind of small lighting equipment, the glue is usually used as an alternative scheme. Although the glue bonding solves the lens installation problem to some extent, but its long-term reliability is worrying.

[0004] Specifically, the lens bonded by glue often loosens or even falls off due to the gradual failure of the bonding property of the glue after a long time of use. Once this situation occurs, not only the normal lighting effect of the lighting equipment will be affected, but also other parts of the equipment can be damaged, thereby shortening the service life of the entire lighting equipment. SUMMARY

[0005] Therefore, the utility model aims at overcoming the deficiencies in the prior art, and provides a lens fixing device and lighting equipment.

[0006] The utility model provides the following technical scheme:

[0007] A lens fixing device, comprising a lens, a shell, and an adhesive matrix.

[0008] The side wall of the lens is provided with a protrusion; the shell is used for installing a lighting device, and the shell has a mounting groove corresponding to the lens; an annular matching groove corresponding to the protrusion is formed in the inner side wall of the mounting groove; the lens is installed in the mounting groove and at least partially falls into the matching groove; the adhesive matrix is filled in the matching groove and is bonded with the lens and the inner wall of the matching groove, respectively.

[0009] As a further improvement of the above technical scheme, the side wall of the lens is further provided with a groove, and the groove is aligned with the matching groove when the lens is installed in the mounting groove.

[0010] As a further improvement of the above technical solution, the plurality of protrusions and the plurality of recesses are alternately arranged along the edge line direction of the fitting groove.

[0011] As a further improvement of the above technical solution, the protrusions and the recesses are long strips arranged along the edge line direction of the fitting groove.

[0012] As a further improvement of the above technical solution, the cross-sectional area of the protrusion away from the top end of the lens is smaller than the cross-sectional area of the protrusion close to the bottom of the lens, and the opening area of the recess is larger than the groove bottom area of the recess.

[0013] As a further improvement of the above technical solution, the side wall of the lens is further provided with a ring-shaped sealing groove, and a sealing ring is arranged in the sealing groove.

[0014] As a further improvement of the above technical solution, the protrusion is located between the sealing groove and the end of the lens close to the shell.

[0015] As a further improvement of the above technical solution, the light-transmitting surface of the lens is an arc-shaped surface protruding away from the shell.

[0016] As a further improvement of the above technical solution, the end surface of the light-transmitting surface away from the shell is provided with a plurality of ring platforms, and the plurality of ring platforms are concentrically and equidistantly arranged.

[0017] As a further improvement of the above technical solution, the adhesive matrix is a cured glue.

[0018] The utility model also provides a lighting device which comprises the lens fixing device of any one of the above.

[0019] Compared with the related art, the utility model has the beneficial effects that:

[0020] The lens fixing device provided by the utility model aims to optimize the installation process and stability of the lens on the shell of the lighting device. In specific operation, first, the adhesive matrix in a viscous state is filled into the fitting groove inside the inner side wall of the installation groove. Then, the lens is installed into the installation groove of the shell. In this process, the protruding structure on the side wall of the lens extrudes the previously filled adhesive matrix and falls into the fitting groove. This action not only realizes the preliminary relative clamping between the lens and the installation groove, but also promotes the establishment of a firm adhesive connection between the lens and the installation groove of the shell through the adhesive properties of the adhesive matrix itself.

[0021] With the passage of time, the adhesive matrix will gradually solidify, which not only enhances its structural stability, but also ensures that it is firmly confined inside the matching groove. At the same time, the solidified adhesive matrix can effectively limit the convex of the lens, thereby ultimately ensuring the accuracy of the relative position between the lens and the shell. Such a design greatly improves the overall reliability and practicality of the lighting device, making the installation of the lens more stable and less likely to shift or fall off.

[0022] It is worth mentioning that the utility model discloses a cleverly set convex structure on the lens, realizes multiple advantages. On the one hand, these convexes can significantly increase the contact area between the adhesive matrix and the lens, thereby effectively improving the bonding effect, making the connection between the lens and the shell more closely and reliably. On the other hand, the convex structure can also cleverly cooperate with the adhesive matrix to effectively clamp the lens. This design takes into account the possibility of reduced adhesion of the adhesive matrix during long-term use of the lighting device. Even if the adhesion of the adhesive matrix decreases, the convex structure can still stably clamp and limit the position of the lens, thereby ensuring that the lighting device can maintain its reliability and practicality for a long time.

[0036] In combination Figure 2 , Figure 3 The embodiment of the present utility model provides a lens fixing device which comprises a lens 200, a shell 300 and an adhesive matrix 400.

[0037] The side wall of the lens 200 is provided with a protrusion 210; the shell 300 is used for installing a lighting device 110, and the shell 300 is provided with a mounting groove 310 corresponding to the lens 200; the inner side wall of the mounting groove 310 is provided with a ring-shaped matching groove 311 corresponding to the protrusion 210; the lens 200 is installed in the mounting groove 310 and at least part of it falls into the matching groove 311; the adhesive matrix 400 is filled in the matching groove 311 and is adhered to the lens 200 and the inner wall of the matching groove 311 respectively; specifically, the adhesive matrix 400 is in a viscous state when filled, and will solidify after a period of rest.

[0038] The lens fixing device provided by the embodiment aims to optimize the installation process and stability of the lens 200 on the shell 300 of the lighting device 100. In specific operation, first, the adhesive matrix 400 in a viscous state is filled into the matching groove 311 on the inner side wall of the mounting groove 310. Then, the lens 200 is installed into the mounting groove 310 of the shell 300. In this process, the protrusion 210 structure on the side wall of the lens 200 will extrude the previously filled adhesive matrix 400 and fall into the matching groove 311. This action not only realizes the preliminary relative clamping between the lens 200 and the mounting groove 310, but also promotes the establishment of a firm adhesive connection between the lens 200 and the mounting groove 310 of the shell 300 through the adhesive property of the adhesive matrix 400 itself.

[0039] With the passage of time, the adhesive matrix 400 will gradually solidify, which not only enhances its structural stability, but also ensures that it is limited inside the fitting groove 311. At the same time, the solidified adhesive matrix 400 can effectively limit the convex 210 of the lens 200, thereby ultimately ensuring the accuracy of the relative position between the lens 200 and the shell 300. Such a design greatly improves the overall reliability and practicability of the lighting device 100, making the installation of the lens 200 more stable and less likely to shift or fall off.

[0040] It is worth mentioning that the utility model realizes multiple advantages by setting the convex 210 structure on the lens 200. On the one hand, these convexes 210 can significantly increase the contact area between the adhesive matrix 400 and the lens 200, thereby effectively improving the adhesion effect and making the connection between the lens 200 and the shell 300 more tight and reliable. On the other hand, the convex 210 structure can also cleverly cooperate with the adhesive matrix 400 to effectively clamp the lens 200. This design takes into account the possibility of reduced adhesion performance of the adhesive matrix 400 during long-term use of the lighting device 100. Even if the adhesion of the adhesive matrix 400 decreases, the convex 210 structure can still stably clamp and limit the position of the lens 200, thereby ensuring that the lighting device 100 can maintain its reliability and practicability for a long time.

[0041] As shown in Figure 4 In some specific embodiments, the side wall of the lens 200 is also provided with a groove 220, and when the lens 200 is installed in the mounting groove 310, the groove 220 is aligned with the fitting groove 311. Specifically, when the lens 200 is installed in place, the alignment of the groove 220 with the fitting groove 311 not only provides an accurate reference for the subsequent adhesion process, but also, through the precise correspondence between the groove 220, the convex 210 and the fitting groove 311, the adhesive matrix 400 will form a obvious convex portion at the groove 220 and a corresponding concave portion at the convex 210 when it is injected and solidified due to its own physical properties. This unique structure not only greatly increases the contact area between the lens 200 and the adhesive matrix 400, thereby effectively improving the adhesion between the two, ensuring the stability of the installation of the lens 200, but also further enhances the limiting reliability of the adhesive matrix 400 to the lens 200 after solidification through physical locking.

[0042] In some specific embodiments, the convex 210 and the groove 220 are each provided with a plurality of convexes 210 and grooves 220, which are alternately arranged along the edge direction of the fitting groove 311, further improving the reliability of the adhesive matrix 400 to the lens 200.

[0043] Specifically, the presence of multiple protrusions 210 means that multiple physical support points are formed between the lens 200 and the mounting structure, which can more effectively disperse various stresses borne by the lens 200 after the curing of the adhesive matrix 400, including stresses caused by external factors such as temperature changes, mechanical vibrations, etc., thereby improving the stability of the lens 200 installation. Similarly, the provision of multiple grooves 220 also provides more embedding space for the adhesive matrix 400, so that the adhesive matrix 400 can more fully penetrate into the tiny gap between the lens 200 and the mounting structure, forming a more secure adhesive force.

[0044] More critically, the alternating arrangement of protrusions 210 and grooves 220 along the edge line direction of the mating groove 311 allows the adhesive matrix 400 to form a kind of "locking" structure during the curing process. This structure not only enhances the connection strength between the lens 200 and the mounting structure, but also further improves the limiting reliability of the adhesive matrix 400 to the lens 200. Even in the case of changes in external environment, such as temperature fluctuations, humidity changes, or mechanical impact, this alternating arrangement of protrusions 210 and grooves 220 can effectively prevent the lens 200 from shifting or loosening, ensuring long-term stability and reliability between the lens 200 and the mounting structure.

[0045] In some specific embodiments, the protrusions 210 and the grooves 220 are both long strips arranged along the edge line direction of the mating groove 311. Since the protrusions 210 or the grooves 220 extend along the edge line direction of the mating groove 311, they can more effectively disperse the stress that may be generated during the installation of the lens 200, avoiding structural damage caused by stress concentration. This design makes the lens 200 more stable after installation and less likely to shift or loosen, thereby ensuring long-term stable connection between the lens 200 and the mounting structure.

[0046] Secondly, the long strip-shaped protrusions 210 and grooves 220 provide a wider contact area for the adhesive matrix 400. When the adhesive matrix 400 is filled between the protrusions 210 and the grooves 220, it can form a more secure adhesive force, thereby further improving the connection strength between the lens 200 and the mounting structure. This tight adhesive force not only helps to improve the shock resistance of the lens 200, but also maintains the stability of the lens 200 under extreme environmental conditions, ensuring the normal operation of the device.

[0047] In some embodiments, the protrusion 210 has a top end area smaller than a bottom cross-sectional area close to the bottom of the lens 200, forming a tapered structure. The groove 220 has an opening area larger than a groove bottom area, presenting a gradually narrowing shape. Such design brings multiple advantages. First, the tapered structure of the protrusion 210 makes it easier to slide into the fitting groove 311 when the lens 200 is installed into the mounting groove 310, greatly reducing the difficulty of installation. The tapered structure guides the protrusion 210 to gradually penetrate along the edge of the fitting groove 311 until it is fully seated, thus simplifying the installation process and improving installation efficiency.

[0048] Second, the design of this shape also takes into account the viscous properties of the adhesive matrix 400. During the bonding process, due to the special shape of the protrusion 210 and the groove 220, the adhesive matrix 400 can be more evenly distributed when filling these structures, effectively reducing the generation of voids or bubbles. The gradually expanding bottom cross-sectional area of the protrusion 210 and the gradually narrowing shape of the groove 220 provide a gradual transition space for the adhesive matrix 400, allowing it to more fully penetrate into the small gaps between the protrusion 210 and the groove 220, forming a more secure bond.

[0049] In some embodiments, the lens 200 is also provided with a ring-shaped sealing groove 230 on the side wall, and a sealing ring 231 is arranged in the sealing groove 230 to ensure the sealing fit between the lens 200 and the mounting groove 310, improving the waterproof performance of the housing 300.

[0050] In some embodiments, the protrusion 210 is located between the sealing groove 230 and the end of the lens 200 close to the housing 300, so that the sealing ring 231 can protect the adhesive matrix 400 from moisture, dirt and other adverse factors, preventing erosion and damage to the adhesive matrix 400, thus ensuring that the adhesive matrix 400 can maintain its excellent bonding performance for a long time.

[0051] In some embodiments, the light-transmitting surface 240 of the lens 200 is an arc-shaped surface protruding away from the housing 300. The arc-shaped design not only brings visual aesthetics, making the overall shape of the lens 200 more smooth, but more importantly, it significantly improves the function. Since the arc-shaped surface protrudes outward, it can provide a larger effective light-transmitting surface 240 than a flat or concave design. This means that under the same size constraints of the housing, the arc-shaped lens 200 can allow more light to pass through, thus improving the overall optical performance of the device.

[0052] In some specific embodiments, the light-transmitting surface 240 is provided with a plurality of ring platforms on the side of the end surface of the shell 300. These ring platforms are not only appropriate in number, but also present a concentric and equidistant distribution state.

[0053] Through the arrangement of ring platforms, the light passing through the lens 200 can be effectively guided and regulated. The concentric and equidistant ring platform structure can ensure that the light propagates according to the predetermined path when passing through the lens 200, avoiding disordered scattering and energy loss of the light. In this way, when the light emitted by the lighting device 100 passes through the lens 200, a clear and bright illumination range can be formed, which not only meets the lighting needs, but also improves the utilization efficiency of the light.

[0054] More noteworthy is that the concentric and equidistant arrangement of the plurality of ring platforms also gives the lens 200 certain aesthetic and decorative properties. These ring platforms form a sense of hierarchy in vision, making the overall modeling of the lens 200 more three-dimensional and lively. This design not only improves the ornamental properties of the lens 200, but also enhances the overall texture and grade of the lighting device 100 to some extent.

[0055] In addition, the arrangement of ring platforms also helps to improve the mechanical strength and stability of the lens 200. During the installation and use of the lens 200, the ring platforms can act as an additional support structure to effectively disperse and resist stress and impact from the outside, thereby protecting the lens 200 from damage. This design not only prolongs the service life of the lens 200, but also improves the reliability and durability of the lighting device 100.

[0056] In some specific embodiments, the adhesive matrix 400 is a cured glue, specifically a high molecular compound that can rapidly cure under certain conditions (such as temperature, humidity, or air pressure) to form a solid adhesive body.

[0057] The reason why this cured glue is chosen is that it has many significant advantages. First, the cured glue can release a large amount of heat during the curing process, which can accelerate the cross-linking reaction between the high molecular chains, allowing the cured glue to form a solid structure in a short time, thereby ensuring the firm connection between the lens 200 and the mounting groove 310. This fast curing speed not only improves the production efficiency, but also helps to reduce the production cost.

[0058] Secondly, the adhesive formed by the cured glue has high strength and toughness, and can withstand large tensile, compressive and shear stresses, thus effectively protecting the lens 200 from damage during installation. At the same time, the cured glue can also fill the tiny gaps between the lens 200 and the mounting groove 310, forming a dense protective layer to prevent the intrusion of harmful substances such as moisture and dust, thereby improving the reliability and durability of the entire lighting equipment 100.

[0059] Furthermore, the cured adhesive possesses excellent transparency and optical properties, ensuring that light passing through the lens 200 is not reflected or refracted due to obstruction by the cured adhesive, thus guaranteeing the light output efficiency and clarity of the lighting device 100. This is particularly important for applications requiring high-brightness, high-definition lighting.

[0060] It is important to note that the curing conditions of the adhesive need to be strictly controlled. Excessive temperature or humidity may cause the adhesive to cure prematurely or incompletely, thus affecting its bonding performance and optical properties. Therefore, in practical applications, appropriate curing conditions must be selected based on the specific type of adhesive and the material of the lens 200 to ensure optimal bonding and optical performance.

[0061] like Figure 1 As shown, the embodiments of this utility model also provide a lighting device 100. The lighting device 100 can be divided into outdoor lighting device 100 and indoor lighting device 100, depending on its usage scenario. It includes any of the lens fixing devices described in the above embodiments.
