Split type lens frame

Abstract

The utility model relates to a split type lens frame which is formed by splicing a plurality of support units. The support unit comprises a stand column. Three or four splice plates are evenly distributed on the periphery of the stand column. The middle part of the top surface of the splice plate protrudes to form a partition plate; the top faces of the two sides of the partition plate form a supporting face used for supporting a lens. A splicing part is formed at the far end, away from the stand column, of the splicing plate. A split type structure is adopted, a traditional integrated lens frame is abandoned, and the situation that the development cost of a mold is greatly increased when the size of a lamp is increased is avoided. Due to the fact that a large complex integrated mold does not need to be manufactured in a split mode, the support units are manufactured through a plurality of relatively simple and small molds, the mold opening cost is greatly reduced, and especially for large-size lamp projects, the cost advantage is more remarkable.

This kind of holder is mostly made by injection molding process. However, once the size of the lamp is large, the disadvantages of this traditional integrated lens holder are highlighted. On the one hand, with the increase of the size of the lamp, the mold development cost and raw material cost of the integrated holder will increase significantly, which will significantly increase the manufacturing cost. On the other hand, the control requirements of the process parameters are high during the injection molding production process of the large size integrated holder, and the process difficulty increases sharply, and a slight mistake may easily cause product defects. Moreover, due to the integrated structure, it is difficult to ensure that the support heights of all parts for multiple lenses are completely consistent in actual production, which may cause deviation of the outgoing light beams of different lenses, affecting the overall lighting and stage presentation effect of the lamp.

[0027] Embodiment, please refer to Figures 1-2 as shown:

[0028] A split lens holder is spliced by a plurality of support units 10; the support unit 10 comprises a stand 100; the stand 100 is uniformly distributed with three or four splicing plates 110 on the outer periphery; the stand 100 serves as the core support structure of the support unit 10, providing stable support force in the vertical direction for the entire support. It bears the weight from the lens and the splicing plate 110, ensures that the support will not tilt and sway in various use scenarios of the lamp, guarantees the stability of the lens position, and further ensures the accuracy of the outgoing light beam;

[0029] The top surface of the splicing plate 110 is raised in the middle to form a partition plate 120 extending along the direction of the top surface; the top surface on both sides of the partition plate 120 constitutes a support surface 130 for supporting the lens; the partition plate 120 plays a role in separation and positioning, clearly defining the placement position of the lens on the support surface 130, preventing the lens from moving in the horizontal direction, ensuring the precise butt joint of the lens with the light beam path, and effectively improving the controllability of the lighting and stage effect. The support surface 130 on both sides of the partition plate 120 provides direct bearing support for the lens, making large-area contact with the lens, dispersing pressure, reducing the risk of local deformation of the lens, protecting the optical performance of the lens from being damaged, and prolonging the service life of the lens.

[0030] The distal end of the splicing plate 110 away from the stand 100 forms a splicing part. The split structure discards the traditional integrated lens holder, avoiding a substantial increase in mold development costs when the size of the lamp increases. Because the split type does not require the manufacture of large and complex integrated molds, but rather a plurality of relatively simple and small molds are used to manufacture the support unit 10, the mold opening cost is greatly reduced, especially for large size lamp projects, the cost advantage is more significant. It solves the problem of poor consistency of large size lens holders. The integrated structure is difficult to ensure the consistency of the support height for the lens in various places when producing large size supports due to the difficulty of the process, while the split structure decomposes the large size into multiple small units for splicing, and uses the edge of the lens to limit the height of the top of the support unit 10, thereby ensuring the consistency of the support height.

[0031] As Figure 1 And Figure 4As shown, in an embodiment, the outer periphery of the column 100 is uniformly distributed with three splicing plates 110; the layout of the three splicing plates 110 lays the foundation for the subsequent formation of a hexagonal lens mounting portion 30, adapts to a hexagonal lens structure, realizes close and stable splicing combination, optimizes space utilization, and meets the requirements of lamp optical design on lens layout. The hexagonal lens design perfectly adapts to the hexagonal mounting portion formed by splicing a plurality of support units 10, and the lens edge part limits the height of the top of the support unit 10. This self-limiting mechanism ingeniously solves the problem of consistent height adjustment of the support unit 10. During the locking of the lens, the lens automatically unifies the height of the plurality of support units 10 connected with each other, without the need for complex additional leveling process, greatly improving the lens mounting precision, effectively guaranteeing the uniformity and accuracy of the lamp exit beam, and meeting the strict requirements of professional stage lighting and searchlight on high-quality output of light beam.

[0032] In an embodiment, the outer periphery of the column 100 is uniformly distributed with four splicing plates 110; the layout of the four splicing plates 110 lays the foundation for the subsequent formation of a quadrilateral lens mounting portion 30, adapts to a quadrilateral lens structure, realizes close and stable splicing combination, optimizes space utilization, and meets the requirements of lamp optical design on lens layout.

[0033] In an embodiment, the splicing portion includes a stop plate 140 formed by extending outward from the distal end of the splicing plate 110 away from the column 100; the thickness of the stop plate 140 is half the thickness of the splicing plate 110. The stop plate 140 extends outward from the distal end of the splicing plate 110, which plays a precise positioning blocking role during the splicing of a plurality of support units 10. When adjacent support units 10 are spliced, the stop plates 140 contact each other, which can quickly determine the relative position of the two units in that direction, effectively avoiding problems such as misplacement and deviation during splicing, greatly improving the efficiency of splicing and assembly, and reducing assembly time. For large-scale lamp production, it can significantly improve production efficiency.

[0034] The stop plate 140, as part of the splicing portion, has a thickness of half the thickness of the splicing plate 110, and when adjacent support units 10 are spliced, the stop plates 140 abut each other, and the thickness of the two stop plates 140 after abutting is consistent with the thickness of the splicing plate 110. It not only ensures that the stop plate 140 has sufficient structural strength to realize precise stopping function, but also effectively avoids occupying too much space due to excessive thickness, making the overall structure after splicing more compact. In the limited space environment inside the lamp, the compact structure creates good conditions for optimizing the layout, making the installation and wiring of other components more convenient, and effectively improving the overall integration of the lamp.

[0035] The structure of the stop plate 140 allows abutting limiting when adjacent stop plates 140 are spliced, which can avoid movement of the stop plate 140 in the plane, such as misplacement and deviation, but can allow a slight movement of the stop plate 140 along the axial direction of the column 100, which provides conditions for balancing the consistency of the top height of the support unit 10. The lens edge part is used to limit the top height of the support unit 10, which solves the problem of adjusting the height consistency of the support unit 10. During the locking of the lens, the lens automatically unifies the height of the multiple support units 10 connected, without the need for complex additional leveling process, which greatly improves the lens installation precision.

[0036] In an embodiment, the stop plate 140 is connected to one of the support surfaces 130; the direction of the splicing plate 110 from the support surface 130 connected to the stop plate 140 to another support surface 130 is the first direction, and the first directions of the multiple splicing plates 110 are in the same direction, for example, the multiple first directions form a clockwise direction or a counterclockwise direction. The first directions of the multiple splicing plates 110 are in the same direction, which makes the entire lens mounting frame have clear directionality and regularity. In the production and assembly link, workers can quickly identify and arrange the support units 10 according to the unified direction, reducing the operation difficulty

[0037] In an embodiment, the first directions of the multiple splicing plates 110 can also be in different directions. This structure increases the types of support units 10, but can still be assembled to form a lens holder;

[0038] In an embodiment, the bottom of the column 100 is provided with a bottom plate 150; the bottom plate 150 is connected to the splicing plate 110; and the bottom plate 150 extends beyond the side of the splicing plate 110 to form a stabilizing plate 160. The connection of the bottom plate 150 and the splicing plate 110 provides a more stable support foundation for the column 100 and the entire support unit 10, and increases the overall stability of the structure. During long-term use of the lamp, it can better withstand external forces in all directions, reduce shaking and deformation, and prolong the service life; the stabilizing plate 160 increases the contact area, making the installation stability of the support unit 10 stronger;

[0039] In an embodiment, a reinforcing plate 170 is connected between the outer periphery of the column 100 and the bottom plate 150. The reinforcing plate 170 is equivalent to a reinforcing rib, and the reinforcing plate 170 can provide additional support between the column 100 and the bottom plate 150, making the connection more stable, enhancing the overall structural strength, ensuring the straightness of the column 100 under stress, and further improving the stability and reliability of the lens installation.

[0040] In one embodiment, a fixing seat 151 is provided at the bottom of the base plate 150; the fixing seat 151 is located at the bottom of the splicing plate 110 at the far end away from the column 100. The fixing seat 151 increases the contact area and connection points between the base plate 150 and the external mounting structure, making the installation stability of the bracket unit 10 stronger; the fixing seat 151 can be a fixing seat 151 for connecting screws formed by a protrusion at the bottom of the base plate 150, and the fixing seat 151 is provided with a connecting hole, or it can be a connecting hole for connecting screws provided on the base plate 150;

[0041] like Figure 3 As shown, in one embodiment, it further includes a sealing unit 20 disposed on the outer periphery for forming a closed lens mounting portion 30; the sealing unit 20 includes a second column 200; the outer periphery of the second column 200 is provided with two second splicing plates 210; the sealing unit 20 is used to cooperate with the support unit 10 to form more lens mounting portions 30. For example, when the support unit 10 includes three splicing plates 110, its outer ring will have an unsealed structure after splicing, and the middle of the spliced ​​lens holder will have multiple complete lens mounting portions 30, while the unsealed space on the periphery will be wasted. By adding the sealing unit 20, the unsealed space can be effectively utilized to form lens mounting portions 30; when the included angle between the two second splicing plates 210 is 120°, it can effectively cooperate with the support unit 10; in one embodiment, when the support unit 10 includes four splicing plates 110, the included angle between the two second splicing plates 210 of the sealing unit 20 is set to 90° to effectively cooperate with the support unit 10.

[0042] The second splicing plate 210 has a second partition 220 protruding from the center of its top surface; the top surfaces on both sides of the second partition 220 form a second support surface 230 for supporting the lens; a splicing portion is formed at the far end of the second splicing plate 210 away from the column 100; the splicing portion includes a second stop plate 240 extending outward from the far end of the second splicing plate 210 away from the second column 200; the thickness of the second stop plate 240 is half the thickness of the second splicing plate 210. The second stop plate 240 is connected to one of the second support surfaces 230; the direction from the second support surface 230 connected to the second stop plate 240 to the other second support surface 230 on the second splicing plate 210 is the second direction, and the second directions of the two second splicing plates 210 are in the same direction; the bottom of the second column 200 is provided with a second base plate 250; the second base plate 250 is connected to the second splicing plate 210; the second base plate 250 extends beyond the side of the second splicing plate 210 to form a second stabilizing plate 260; a second reinforcing plate 270 is connected between the outer periphery of the second column 200 and the second base plate 250; other beneficial effects of the various structures of the closed unit 20 are the same as those of the support unit 10, and will not be described in detail here.

[0043] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent transformation or direct or indirect application in the related technical field based on the content of the present application specification and drawings is also included in the patent protection scope of the present application.
