Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lamps and lanterns especially, relate to a lamp holder anti-twist subassembly. BACKGROUND

[0002] In the lamp head assembly structure of searchlight or large size stage lamp, usually a plurality of lens light emitting components are integrated, which need to be fixed accurately on the mounting plate to ensure the light emitting effect. However, the actual situation is that, due to the relatively large size of the mounting plate and the close arrangement of the numerous lens light emitting components, it brings many restrictions when designing the support column position of the mounting plate.

[0003] Usually, due to the influence of space layout, the support column is arranged circumferentially along the bottom of the mounting plate. This arrangement brings a series of problems. First, from the aspect of structural stability, the circumferentially arranged support column is difficult to provide comprehensive and effective support for the mounting plate, resulting in poor stability of the entire support structure. Secondly, due to the mounting plate not only carrying a plurality of lens light emitting components, but also possibly including other related optical elements and electronic elements, etc., the overall weight of the components on the mounting plate is large. Especially during the installation process, when subjected to external installation force, the large weight will further increase the risk of torsion of the mounting plate;

[0004] Usually, it is manifested that the mounting plate tilts to one side, so that the mounting plate is twisted and deviated from the original plane. It can also be understood that the preset installation position requires the mounting plate to be parallel to the base plane, but under the action of external installation force during installation, the mounting plate is not parallel to the base plane, and the connection between the mounting plate and the support column is twisted. In another case, the mounting plate may be twisted / deformed by itself, so that its installation surface is deformed and not parallel to the base plane. In another case, due to the use of searchlight or large size stage lamp, it will be hoisted or used at an angle, and the components actually installed on the mounting plate have a large weight. When used at an angle, the weight of the components on the mounting plate under the action of gravity may also cause the mounting plate to twist. Once the mounting plate is twisted, its plane will no longer be flat. This uneven surface will directly affect the installation position of the lens light emitting component, making it deviate from the original design position. Even a small change in position may have a significant impact on the light emitting effect. For example, it may cause the projection direction of the light to deviate, so that the illumination area cannot achieve the expected effect; or cause inaccurate focusing of the light, affecting the brightness and clarity of the light; or even cause scattering of the light, reducing the light emitting efficiency and quality of the entire lamp head assembly, and thus affecting the lighting effect and stage performance effect of the searchlight or large size stage lamp in actual use. SUMMARY

[0008] Further, the top of the installation plate is circumferentially provided with a plurality of second support columns connected to the support plates; the support plates are annularly arranged around the periphery of the lens light emitting assembly; the outer side of the support plates abuts against the inner wall of the lamp shell.

[0009] Further, the support plate is composed of a plurality of support plate elements.

[0010] Further, the bottom of the lamp shell is fixedly connected with the base; the top of the lamp shell is provided with a light-transmitting plate.

[0011] Further, a wire passing column is provided between the installation plate and the base; a wire passing hole is provided on the wire passing column.

[0012] Further, the number of support blocks is the same as that of first support columns; the support blocks are fixedly connected with the first support columns.

[0013] Further, the lens light emitting assembly includes a plurality of first lenses and second lenses; the number of first lenses is the same as that of second lenses, and the first lenses and the second lenses are arranged one by one in the mounting slots of the lens holder.

[0014] Further, the support block is connected with the first support column by a screw.

[0015] Further, a limiting protrusion is formed on the support block to cooperate with the side surface of the installation plate to limit the rotation of the support block.

[0016] The utility model has the advantages that: the support blocks are closely matched with the lamp shell from multiple circumferential points, providing additional support force for the installation plate, effectively sharing the weight borne by the installation plate, making the stress on the installation plate in the vertical direction more uniform, thereby significantly enhancing the overall stability of the installation plate and reducing the possibility of twisting due to uneven weight or external force impact. The second support columns and the support plates jointly constitute a cooperative structure system.

[0027] Embodiment, please refer to Figures 1-4 As shown in the figure:

[0028] A lamp holder anti-twist assembly, comprising a base 100;The base 100 is fixedly connected with lamp shell 200;The inside of the lamp shell 200 is formed with a containing space;The containing space is provided with a mounting plate 110 for mounting lens light emitting assembly 160;The bottom of the mounting plate 110 is circumferentially provided with a plurality of first support columns 120 connected with the base 100;The mounting plate 110 is circumferentially provided with a plurality of support blocks 111 abutting against the inner wall of the lamp shell 200;Greatly improve the support condition of mounting plate 110. Support block 111 is closely matched with lamp shell 200 from circumferential multiple points, which provides additional support for mounting plate 110, effectively shares the weight borne by mounting plate 110, so that the stress of mounting plate 110 in the vertical direction is more uniform, thereby significantly enhancing the overall stability of mounting plate 110, reducing the possibility of torsion due to uneven weight or external force impact. Stable mounting plate 110 can ensure that precise components such as lens light emitting assembly 160 are always in the correct installation position, avoid collision, friction and other situations caused by the torsion of mounting plate 110, reduce the risk of component damage, prolong the service life of each component inside the lamp, thereby reducing maintenance cost and maintenance frequency;Because the support block 111 prevents the torsion of the mounting plate 110, the installation angle and position of the lens light emitting assembly 160 can be accurately fixed, the light projection direction can strictly follow the design requirements, and the accuracy of the illumination area is ensured, whether it is used for long-distance searchlight or large-area stage lighting, it can provide high-quality, stable lighting effect, meet the professional application requirements.

[0029] From the perspective of mechanics, the support blocks 111 are equivalent to adding multiple support points between the mounting plate 110 and the lamp shell 200. When the mounting plate 110 bears the gravity from the components above and external forces that may be encountered during installation, these support points will evenly disperse the forces to the lamp shell 200 according to the action and reaction principle. The lamp shell 200, as a relatively stable external structure, can bear and offset these forces to prevent the mounting plate 110 from tilting or twisting due to excessive local stress. For example, if a side of the mounting plate 110 receives a lateral force due to installation operation, the adjacent support block 111 will immediately transmit the force to the lamp shell 200, and the lamp shell 200 will react to the support block 111 with its own rigid structure to keep the mounting plate 110 in a balanced and stable state.

[0030] In an embodiment, the top of the mounting plate 110 is circumferentially provided with multiple second support columns 130 connected to the support plates 140; the support plates 140 are annularly arranged around the periphery of the lens light-emitting assembly 160; the outer side of the support plates 140 abuts against the inner wall of the lamp shell 200. The support plates 140 provide double protection against twisting. The multiple second support columns 130 circumferentially arranged on the top of the mounting plate 110, and the support plates 140 annularly arranged around the periphery of the lens light-emitting assembly 160 and abutting against the inner wall of the lamp shell 200, provide a double protection mechanism for the mounting plate 110. On the one hand, the second support columns 130 enhance the support strength of the top of the mounting plate 110, and work cooperatively with the support structure (support blocks 111) at the bottom to form a three-dimensional support network that limits the displacement and deformation of the mounting plate 110 from multiple dimensions; on the other hand, the support plates 140 further constrain the circumferential rotation of the mounting plate 110 by tightly abutting against the inner wall of the lamp shell 200, especially when dealing with complex installation conditions or structural fatigue after long-term use of the lamp, this double protection can continuously ensure the flatness of the mounting plate 110 and maintain the optimal working state of the lens light-emitting assembly 160.

[0031] The support plates 140 are annularly arranged around the periphery of the lens light-emitting assembly 160, not only serving as support, but also ingeniously utilizing the space around the periphery of the lens light-emitting assembly 160, avoiding the occupation of excessive valuable space inside the lamp, making the internal structure of the lamp more compact and reasonable. This is helpful for integrating more functional components in the limited internal space of the lamp shell 200, improving the overall performance and multifunctionality of the lamp, especially for large-size stage lamps and other lamps with strict space layout requirements.

[0032] Since the support plate 140 is in close contact with the inner wall of the lamp shell 200, the path and area of heat conduction can be increased. During the operation of the lamp, the lens light assembly 160 and other electronic components will generate heat, and the support plate 140 can quickly transfer this heat to the lamp shell 200, which can be effectively dissipated by the large heat dissipation surface area of the lamp shell 200, effectively reducing the temperature inside the lamp, providing a more suitable working environment for each component, and further improving the reliability and stability of the lamp.

[0033] In an embodiment, the support plate 140 is composed of a plurality of support plate elements 141. Designing the support plate 140 as a combination of a plurality of support plate elements 141 greatly simplifies the assembly process of the lamp. In the lamp production workshop, workers can pre-treat each support plate element 141, such as surface cleaning, installation of auxiliary accessories, and other operations, and then accurately assemble these elements inside the lamp. Compared with a large one-piece support plate 140, this modular installation method reduces the requirement for installation space, allowing workers to operate more flexibly inside the limited lamp shell 200, reducing the risk of damage during installation, and improving installation efficiency. When the lamp is in long-term use, if the support plate 140 is damaged or its performance deteriorates, the support plate 140 composed of multiple elements can quickly locate the source of the problem. Maintenance personnel only need to check each element one by one to accurately find the faulty element, without having to spend a lot of time troubleshooting the entire structure as with a one-piece support plate 140. Moreover, when replacing damaged elements, only the corresponding single or few elements need to be disassembled, without the need to disassemble the entire support plate 140, greatly shortening the repair time, reducing the repair cost, ensuring that the lamp can resume normal operation as soon as possible, and reducing the impact on the performance and lighting operation.

[0034] In an embodiment, the bottom of the lamp shell 200 is fixedly connected with the base 100, and the top of the lamp shell 200 is provided with a light-transmitting plate 210.

[0035] In an embodiment, a wire passing column 150 is arranged between the mounting plate 110 and the base 100, and a wire passing hole 151 is arranged on the wire passing column 150. By arranging the wire passing column 150, the wiring inside the lamp head assembly can be facilitated, and the installation process is simplified.

[0036] In an embodiment, the support blocks 111 are the same in number as the first support columns 120; the support blocks 111 are fixedly connected with the first support columns 120. The support blocks 111 and the first support columns 120 work cooperatively to form a stable support network, which can more evenly disperse the weight of the mounting plate 110 and the components above, effectively reduce local stress concentration, and reduce the possibility of deformation or torsion of the mounting plate 110 due to uneven stress, thereby providing a more stable mounting basis for the lens light-emitting assembly 160 and ensuring the consistency and stability of the light-emitting effect thereof. Since the support blocks 111 are fixedly connected with the first support columns 120, the two can be positioned and installed as a whole during installation, which helps to improve the accuracy and repeatability of installation. When installing, workers only need to connect this whole structure with the mounting plate 110 and the lamp shell 200 according to the predetermined position and manner, which can ensure the positional accuracy of the support structure and further ensure the accurate installation position of the lens light-emitting assembly 160, thereby improving the optical performance and overall quality of the lamp. When the lamp is subjected to external forces such as vibration and impact, the fixed connection of the support blocks 111 and the first support columns 120 can make the external forces more effectively transmitted and dispersed between the two. The support blocks 111 transmit the external force to the first support columns 120, which then uniformly distribute the force to the mounting plate 110 and the lamp shell 200. Through this reasonable force transmission path, the anti-external force capability of the overall structure of the lamp is improved, the risk of damage to the lamp due to external force impact is reduced, and the service life of the lamp is prolonged.

[0037] In an embodiment, the lens light-emitting assembly 160 includes a plurality of first lenses 161 and second lenses 162; the first lenses 161 and the second lenses 162 are the same in number and are arranged one by one in the mounting slots of the lens holder 163.

[0038] In an embodiment, the support blocks 111 are connected with the first support columns 120 by a screw 113, which greatly simplifies the assembly process. On the production line of the lamp, workers only need a screwdriver to quickly and accurately position and fix the support blocks 111 to the first support columns 120. Compared with complex connection methods, this method is not only easy to operate, but also can effectively avoid the accumulation of installation errors caused by too many connecting parts. At the same time, the screw connection provides sufficient fastening force to ensure that the support blocks 111 and the first support columns 120 will not easily loosen or displace during use of the lamp, laying a solid foundation for the stability of the entire support structure. For example, in batch production of lamps, this simple and efficient connection method can greatly shorten the assembly time of a single lamp, improve production efficiency, and reduce labor costs.

[0039] In an embodiment, the support block 111 is formed with a limiting protrusion 112 on the side surface of the mounting plate 110 to limit the rotation of the support block 111. The limiting protrusion 112 on the support block 111 is closely matched with the side surface of the mounting plate 110, and is combined with the fixation of a single screw 113 to fundamentally limit the rotational freedom thereof, greatly simplifying the installation structure; when the lamp encounters external force impact, such as vibration during transportation, shaking due to collision with other equipment on the stage, etc., the torsional force transmitted by the mounting plate 110 to the support block 111 will be effectively blocked by the limiting protrusion 112. This enables the support block 111 to always maintain a stable support posture, thereby ensuring that the mounting plate 110 will not be twisted due to accidental rotation of the support block 111, providing a reliable installation platform for the lens light-emitting assembly 160, and maintaining the accuracy and stability of light output.

[0040] It should be noted that the torsion in the utility model includes torsion of the connection between the mounting plate 110 and the support column; also includes torsion / deformation of the mounting plate 110 itself;

[0041] Structural synergy principle: the second support column 130 and the support plate 140 jointly construct a synergistically working structural system. The second support column 130 serves as a vertical support member, extending the action of the support block 111 in the vertical direction, while the support plate 140, by virtue of its large-area abutment with the inner wall of the lamp housing 200, disperses the force to the lamp housing 200, and simultaneously utilizes its annular structure to constrain the deformation of the mounting plate 110. The support block 111 and the support plate 140 act in coordination to ensure that the mounting plate 110 plane always remains flat, maintaining the stable installation state of the lens light-emitting assembly 160.

[0042] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent transformation or direct or indirect application in related technical fields based on the content of the utility model specification and drawings is also included in the patent protection range of the utility model.
