[0028] Embodiment, please refer to Figures 1-4 As shown in the figure:

[0029] A lens mounting structure, comprising a lens holder 10 for mounting lens 20;The lens holder 10 can be an integral structure or a split combined structure;The lens holder 10 is provided with a plurality of polygonal lens mounting parts 30;In an embodiment, the lens mounting part 30 is hexagonal;In an embodiment, the lens mounting part 30 is regular hexagonal;So that the lens mounting part 30 forms a honeycomb structure as a whole, makes full use of space, and is beneficial to reasonably arranging a plurality of lenses 20 in limited lamp space;On the other hand, the hexagonal design makes each lens mounting part 30 clear, which is convenient for subsequent maintenance and debugging of single lens 20, and reduces the influence on the surrounding lenses 20;

[0030] In an embodiment, the lens mounting part 30 comprises a plurality of support plates 31, and a stand 40 is arranged at the connection of adjacent support plates 31;When the lens mounting part 30 is hexagonal, the support plate 31 comprises six pieces;The support plate 31 provides stable support from the bottom of the lens 20, disperses the weight of the lens 20, ensures that the lens 20 remains horizontal and stable during installation and use, and reduces the risk of light beam deviation caused by shaking and displacement. The stand 40 enhances the overall rigidity of the lens mounting part 30, making up for the possible insufficient structural strength of relying solely on the support plate 31;Meanwhile, it also provides a basis for the fixation of the limiting piece 50;

[0031] In an embodiment, the middle part of the top surface of the support plate 31 is raised to form a partition plate 32 extending along the direction of the top surface; the top surface on both sides of the partition plate 32 constitutes a support surface 33 for supporting the lens 20; the lens 20 is accurately positioned in the horizontal direction, avoiding the lens 20 from sliding randomly on the support surface 33. The traditional flat support cannot achieve accurate positioning. The design of the support surface 33 on both sides of the partition plate 32 can not only adapt to the shape of the bottom of the lens 20, but also increase the contact area with the lens 20, ensuring the stability of the support; the partition plate 32 also ensures the reasonable spacing between adjacent lenses 20, avoiding direct contact between the lenses 20 which may damage the lens 20 when under stress;

[0032] In an embodiment, the top of the column 40 is provided with a limiting piece 50 for fixing the lens 20; the bottom of the limiting piece 50 is provided with an arc-shaped abutting surface 51 abutting the surface of the lens 20. The problem of traditional pressing plate being inconvenient to disassemble and unable to flexibly operate a single lens 20 is overcome, and simple and effective fixing and releasing of a single lens 20 is achieved. The arc-shaped abutting surface 51 gently and closely fits the corners of the lens 20, which can firmly fix the lens 20 to prevent it from coming out, and also avoids damaging the surface of the lens 20; only six limiting pieces 50 need to be disassembled to overhaul a single lens 20, greatly reducing the difficulty and time cost of overhaul, and improving the efficiency of equipment maintenance.

[0033] In an embodiment, the bottom of the limiting piece 50 is provided with a positioning plate 52; the thickness of the positioning plate 52 is the same as the thickness of the partition plate 32; the positioning plate 52 is arranged between adjacent lenses 20. The main function of the positioning plate 52 is to be inserted between the lenses 20 to limit the position of the lens 20 from the corners of the lens 20. Since the limiting piece 50 simultaneously contacts the corners of three lenses 20, the consistency of the spacing between multiple lenses 20 can be ensured. Since the limiting of the limiting piece 50 to the lens 20 is concentrated in one point, a single limiting piece 50 cannot effectively ensure the accuracy of the installation position of the lens 20. Therefore, the accurate installation of the position of the lens 20 is the effect of the joint action after all the limiting pieces 50 are installed in place, that is, the adjustment of the spacing between the lenses 20 is automatically realized after all the limiting pieces 50 are installed, which has the advantage of not needing to adjust the position of the lens 20 separately, but directly achieving by installation and fixation, effectively saving adjustment time and improving efficiency. On the other hand, the positioning plate 52 can also be used for quick installation on the column 40. Since the gap between the positioning plate 52 and the lens 20 is clamped, it can facilitate the worker to quickly operate when installing the limiting piece 50, reduce the alignment time, and improve the efficiency;

[0034] In an embodiment, the middle part of the limiting member 50 is provided with a through hole 53; the limiting member 50 is fixedly connected with the stand column 40 through the screw 54 penetrating the through hole 53. The screw 54, as a fastening element commonly used in mechanical connection, has a strong axial tension, and can build a stable connection between the limiting member 50 and the stand column 40 by penetrating the through hole 53 of the limiting member 50 and being screwed into the stand column 40. When it is necessary to maintain the lamp, for example, to replace the damaged lens 20, to overhaul the limiting member 50 or the stand column 40, etc., the connection mode of the limiting member 50 is very convenient, without the need to remove all the pressing plates for maintenance as in the traditional structure.

[0035] In an embodiment, the screw 54 is sleeved with a gasket 55; the gasket 55 cooperates with the limiting member 50 to balance the pressure of the limiting member 50 on the plurality of lenses 20. Since the limiting member 50 acts on the corner parts of the plurality of lenses 20 at the same time, if the pressure distribution is uneven, it is easy to cause the local force of the lens 20 to be too large, which may lead to problems such as slight deformation, rupture or even degradation of optical performance of the lens 20. The intervention of the gasket 55 ingeniously solves this hidden danger. The larger contact area of the gasket 55 can uniformly disperse the fastening pressure transmitted by the screw 54 to the top surface of the limiting member 50, and then make the pressure applied by the limiting member 50 on the corner parts of the plurality of lenses 20 tend to be balanced. This ensures that each part of the lens 20 in contact with the limiting member 50 can work in a safe and stable pressure environment, effectively prolongs the service life of the lens 20, and guarantees the long-term stable lighting effect of the lamp.

[0036] In an embodiment, the screw 54 is sleeved with a balancing block 57; the balancing block 57 abuts against the top of the limiting member 50 to balance the pressure of the limiting member 50 on the plurality of lenses 20; the balancing block 57 is a rubber pad. Since the limiting member 50 needs to simultaneously apply force to the corners of the plurality of lenses 20, it is crucial to ensure uniform distribution of pressure. The balancing block 57 is made of rubber material, which has good flexibility and elastic deformation ability. Compared with ordinary materials, it can more sensitively perceive and adapt to the pressure difference on the top surface of the limiting member 50. When the screw 54 is tightened, the balancing block 57 can automatically adjust the degree of deformation according to the actual force condition of the contact points between the limiting member 50 and the lenses 20, and evenly and gently distribute the pressure from the screw 54 to each action area of the limiting member 50, effectively preventing local stress concentration of the lenses 20 caused by uneven pressure, ensuring the structural integrity of the lenses 20, maintaining their ideal optical performance, and prolonging the service life of the lenses 20; during frequent use of the lamp, external disturbances such as vibration and impact follow suit. The rubber balancing block 57 plays a key role in shock absorption, and its unique molecular structure enables it to have excellent damping properties, efficiently absorbing and dissipating the energy transmitted from the outside to the limiting member 50 and lens 20 system. The elastic properties of the rubber balancing block 57 greatly facilitate the operation of workers during installation. Since it can produce moderate deformation, when the screw 54 is inserted through the balancing block 57 and screwed into the column 40, it can automatically adapt to certain installation errors, such as the concentricity deviation of the screw 54 and the through hole 53, the slight inclination of the limiting member 50, etc., reducing the installation difficulty and improving the assembly efficiency. Moreover, during the debugging stage, if it is necessary to fine-tune the pressure of the limiting member 50 on the lenses 20, only a small torque needs to be applied to the screw 54, and the balancing block 57 can respond flexibly to assist in achieving precise pressure control and help quickly achieve the best lighting effect setting.

[0037] In an embodiment, the screw 54 is sleeved with a gasket 55; the screw 54 is sleeved with a balancing block 57; the balancing block 57 abuts against the top of the limiting piece 50 to balance the pressure of the limiting piece 50 on the plurality of lenses 20; the balancing block 57 is a rubber pad. In this structure, since the balancing block 57 abuts against the top of the limiting piece 50, the gasket 55 is located on the top of the balancing block 57; the gasket 55 cooperates with the rubber balancing block 57 to ensure the reasonable distribution of pressure from different aspects. The gasket 55 generally has a certain hardness and flatness, is located at the uppermost position, first receives the initial pressure of the head of the screw 54, preliminarily disperses the concentrated fastening force by virtue of the large contact area, avoids the damage to the lower components caused by the excessive single-point pressure of the screw 54. And the rubber balancing block 57 further accurately senses and balances the pressure of the limiting piece 50 acting on the corner of the plurality of lenses 20 by virtue of the excellent elastic deformation ability, delicately adjusts the shape according to the actual stress condition, ensures that the pressure on the lenses 20 is uniform and soft, which greatly reduces the risk of damage of the lenses 20 caused by uneven stress, effectively maintains the optical integrity of the lenses 20, prolongs the service life, and ensures the stability and durability of the lighting effect of the lamp.

[0038] In an embodiment, the top of the limiting piece 50 is provided with a containing groove 56; the containing groove 56 is provided with a balancing block 57; the size of the balancing block 57 is greater than the size of the end of the screw 54; the balancing block 57 abuts in the containing groove 56 to balance the pressure of the limiting piece 50 on the plurality of lenses 20; the containing groove 56 provides a dedicated accommodation space for the balancing block 57, so that the balancing block 57 can be accurately positioned on the key pressure area at the top of the limiting piece 50. Since the size of the balancing block 57 is greater than the size of the end of the screw 54, the contact area of the balancing block 57 with the top surface of the limiting piece 50 is larger, and the balancing block 57 can more comprehensively and uniformly receive the pressure applied by the limiting piece 50 to the corners of the plurality of lenses 20. When the lamp is disturbed by various external forces or the pressure fluctuates due to the slight changes of the structure during operation, the balancing block 57 can autonomously adjust the shape in the containing groove 56 by virtue of the good elasticity or flexibility (depending on the material), uniformly disperses the pressure to the contact points of each lens 20, effectively avoids the excessive local stress of the lenses 20, and effectively ensures the structural integrity and optical performance stability of the lenses 20, prolongs the service life of the lenses 20, and lays a solid foundation for the continuous and stable lighting of the lamp. The containing groove 56 also helps to reduce the height of the fixing part and save the internal space.

[0039] In an embodiment, the bottom of the limiting piece 50 is provided with a raised portion 58 matched with the stand 40. The raised portion 58 ensures the effective contact between the limiting piece 50 and the lens 20;

[0040] In an embodiment, the middle column 40 of the lens holder 10 is connected with three support plates 31, and the side column 40 is connected with two support plates 31; the side column 40 is provided with a support block 41 matched with the limiting piece 50 on the side away from the support plate 31. The stability of the limiting piece 50 during installation is ensured by adding the support block 41.

[0041] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent transformation or direct or indirect application in the related technical field by using the content of the present application specification and drawings is also included in the patent protection range of the present application.
