Description

Technical Field

[0001] The present invention relates to the field of lamps, and in particular to a light emitting lamp holder and a lamp. Background Art

[0002] In the lamp head assembly structure of searchlights or large-sized stage lights, multiple lens light-emitting components are usually integrated, and these lens light-emitting components need to be accurately fixed 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 numerous lens light-emitting components arranged closely to each other, there are many restrictions when designing the support column position of the mounting plate.

[0003] Usually, due to the influence of spatial layout, support columns are arranged along the bottom circumference of the mounting plate. This arrangement brings a series of problems. First, from the perspective of structural stability, circumferentially arranged support columns are difficult to provide comprehensive and effective support for the mounting plate, resulting in poor stability of the entire support structure. Secondly, because the mounting plate not only carries multiple lens light-emitting components, but may also include other related optical components and electronic components, the overall weight of the components on the mounting plate is relatively large. Especially during the installation process, when subjected to external installation forces, the greater weight will further increase the risk of twisting of the mounting plate;

[0004] Usually, the mounting plate tilts to one side, causing the mounting plate to twist and deviate 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 no longer 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 also be twisted / deformed by force, causing its own mounting surface to deform and become non-parallel to the base plane; in another case, since searchlights or large-size stage lights are hoisted or tilted when used, 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 may also cause the mounting plate to twist under the action of gravity; and once the mounting plate is twisted, its plane will inevitably no longer be flat. This uneven surface will directly affect the installation position of the lens light-emitting component, causing it to deviate from the original design position. Even a slight position change may have a significant impact on the light-emitting effect. For example, it may cause deviations in the projection direction of light, making it impossible to achieve the expected effect in the illuminated area; or cause inaccurate focusing of light, affecting the brightness and clarity of the light; it may even cause light scattering, reducing the light output efficiency and quality of the entire lamp head assembly, thereby affecting the lighting effect and stage performance of searchlights or large-size stage lights in actual use.

[0022] The beneficial effects of the present invention are:

[0023] 1. The anti-twist component can ensure that the installation position of the mounting plate remains unchanged and also reduce its own torsion;

[0024] 2. The bottom of the split lens bracket is fixed on the mounting plate. Although the bottom of the bracket unit is fixed, since the mounting plate is a porous structure and the bracket unit is relatively independent, in the absence of a limiting structure along the axial direction of the column, there is a small degree of freedom between adjacent splicing plates along the axial direction of the column, which provides a basis for the subsequent automatic leveling of the lens bracket; the edge of the lens abuts against the splicing plate, and the structure of the bracket unit enables the lens to abut against the splicing plates on multiple bracket units at the same time. Under the fixing action of the limiting member, the edge of the lens acts on multiple splicing plates at the same time, so that the top height of the splicing plates tends to be consistent; after all the limiting members are fixed, the top height of the bracket unit is automatically leveled, thereby realizing the flatness adjustment of the mounting plate; the split lens bracket has multiple connection points with the mounting plate, and the lens bracket can achieve the effect of reinforcing ribs, and also effectively enhances the structural strength of the mounting plate, so that when applied to large lamps, the consistency of the lens mounting surface can be effectively guaranteed, and the deformation of the mounting plate affected by the weight of the lens light output component can also be improved by the split structure lens bracket;

[0025] 3. The split-structure lens bracket can also cooperate with the lens, using the structural strength of the lens to assist in enhancing the rigidity of the bracket unit, thereby reducing the deformation of the mounting plate. This structure also solves the problem that the middle part is prone to collapse and deformation when the bottom of the mounting plate is supported only by the first support column arranged circumferentially.

[0026] 4. The support block cooperates closely with the lamp housing at multiple points around the circumference, providing additional support for the mounting plate, effectively sharing the weight borne by the mounting plate, making the force on the mounting plate in the vertical direction more uniform, thereby significantly enhancing the overall stability of the mounting plate and reducing the possibility of torsion due to uneven weight or external force impact.

[0027] 5. The split-type lens holder is used instead of the traditional integrated lens holder, which avoids the sharp 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 uses multiple relatively simple and small molds to make the bracket unit, which greatly reduces the mold opening cost, especially for large-size lamp projects, the cost advantage is more significant.

[0028] 6. The structure of the light shield fully considers the internal space layout of the lamp. The space between the light-emitting unit and the light-emitting component is reasonably utilized, which does not affect the normal light output of the lamp and leaves enough space for the installation and operation of the light shield. The setting of the energy storage module can realize the automatic control of the drive component when the power is off. Whether it is daily power outage, sudden power outage or manual power off, once the equipment is powered off, the energy storage module can control the drive component to accurately control the movement of the light shield. The whole process does not require manual intervention, which is efficient and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] Example:

[0054] like Figure 2 As shown, a light emitting lamp head includes: a base 10, on which a light emitting unit 90 is provided; a lamp housing 70, which is fixed on the base 10 and forms an accommodating space inside; a lens light emitting assembly 60, which is arranged in the accommodating space and is spaced apart from the light emitting unit 90;

[0055] like Figure 2-4 As shown, the anti-twist component is arranged between the lens light output component 60 and the inner wall of the lamp housing 70; the anti-twist component abuts against the inner wall of the lamp housing 70, and can use the lamp housing 70 to leverage, thereby improving the support condition of the lens light output component 60; multiple additional support points are provided for the lens support component, thereby effectively avoiding the possibility of twisting;

[0056] The lens light output assembly 60 includes a lens bracket 63 for supporting the lens; the bottom of the lens bracket 63 is connected to the mounting plate 11; the mounting plate 11 is connected to the anti-twist assembly; further, the anti-twist assembly is mainly used to reduce the deformation of the mounting plate 11; since the lens bracket 63 is provided with a plurality of through holes for the light of the light-emitting unit 90 to pass through, the corresponding mounting plate 11 needs to be provided with a plurality of through holes, which leads to a reduction in the strength of the mounting plate 11. During installation, the mounting plate 11 is easily deformed, thereby affecting the flatness of the lens installation; the anti-twist assembly can ensure that the installation position of the mounting plate 11 remains unchanged, and also reduces its own torsion;

[0057] like Figure 6-7 As shown, the lens bracket 63 is formed by splicing a plurality of bracket units 631 to form a lens mounting portion 630 for mounting a lens;

[0058] like Figure 8As shown, the bracket unit 631 includes a column 6310 and a plurality of splicing plates 6311 evenly distributed around the column 6310; adjacent bracket units 631 are connected by the splicing plates 6311; adjacent splicing plates 6311 have a degree of freedom along the axis of the column 6310; the top portion of the splicing plate 6311 supports the lens; the column 6310 is provided with a stopper 633 for simultaneously abutting against the corners of multiple lenses; under the action of this structure, the bottom of the split lens bracket is fixed on the mounting plate 11, Although the bottom of the bracket unit 631 is fixed, since the mounting plate 11 is a porous structure, the bracket unit 631 is relatively independent. In the absence of a limiting structure along the axial direction of the column 6310, adjacent splicing plates 6311 have a tiny degree of freedom along the axial direction of the column 6310, which provides a basis for the subsequent automatic leveling of the lens bracket; the edge of the lens abuts against the splicing plate 6311, and the structure of the bracket unit 631 enables the lens to be simultaneously aligned with the splicing plates on multiple bracket units 631. 6311 abuts, and under the fixing action of the limiter 633, the edge of the lens acts on multiple splicing plates 6311 at the same time, so that the top height of the splicing plates 6311 tends to be consistent; after all the limiters 633 are fixed, the top height of the bracket unit 631 is automatically leveled, thereby realizing the flatness adjustment of the mounting plate 11; and the split lens bracket and the mounting plate 11 have multiple connection points, and the lens bracket can achieve the effect of reinforcing ribs, and also effectively enhance the structural strength of the mounting plate 11, so that when applied to large lamps, it can effectively ensure the consistency of the lens mounting surface, and the deformation of the mounting plate 11 affected by the weight of the lens light output component 60 can also be improved by the split structure lens bracket 63; the split structure lens bracket 63 can also cooperate with the lens, and use the structural strength of the lens to assist in enhancing the rigidity of the bracket unit 631, so as to reduce the deformation of the mounting plate 11; this structure also solves the problem that the middle part is easy to collapse and deform when the bottom of the mounting plate 11 is supported only by the first support column 20 arranged circumferentially;

[0059] In one embodiment, the bottom of the mounting plate 11 is provided with a plurality of first support columns 20 connected to the base 10 in the circumferential direction; the anti-twist assembly includes a plurality of support blocks 12 provided in the circumferential direction of the mounting plate 11 and abutting against the inner wall of the lamp housing 70; the support condition of the mounting plate 11 is greatly improved. The support blocks 12 are closely matched with the lamp housing 70 at multiple points in the circumferential direction, providing additional support force for the mounting plate 11, effectively sharing the weight borne by the mounting plate 11, making the force on the mounting plate 11 in the vertical direction more uniform, thereby significantly enhancing the overall stability of the mounting plate 11 and reducing the possibility of twisting due to uneven weight or external force impact.

[0060] The stable mounting plate 11 can ensure that the lens light output assembly 60 and other precision components are always in the correct installation position, avoiding collision, friction and the like caused by the twisting of the mounting plate 11, reducing the risk of component damage, extending the service life of the components inside the lamp, and thus reducing the repair cost and maintenance frequency;

[0061] Since the support block 12 prevents the mounting plate 11 from twisting, the mounting angle and position of the lens light output assembly 60 can be accurately fixed, and the light projection direction can be strictly in accordance with the design requirements, thereby ensuring the accuracy of the lighting area. Whether it is used for long-distance searchlighting or large-area stage lighting, it can provide high-quality and stable lighting effects to meet professional application needs.

[0062] From a mechanical point of view, the support block 12 is equivalent to adding multiple support points between the mounting plate 11 and the lamp housing 70. When the mounting plate 11 is subjected to the gravity from the components above and the external forces that may be received during the installation process, these support points will evenly distribute the force to the lamp housing 70 based on the principle of action and reaction. As a relatively stable external structure, the lamp housing 70 can withstand and offset these forces, preventing the mounting plate 11 from tilting or twisting due to excessive local force. For example, if one side of the mounting plate 11 is subjected to a lateral force due to the installation operation, the adjacent support block 12 will immediately transfer the force to the lamp housing 70. The lamp housing 70 reacts to the support block 12 with its own rigid structure, so that the mounting plate 11 remains in a balanced and stable state.

[0063] In one embodiment, the anti-twist assembly includes a support plate 40 arranged at intervals on the top of the mounting plate 11; the support plate 40 is connected to the mounting plate 11 through a second support column 30; a plurality of second support columns 30 connected to the support plate 40 are arranged circumferentially on the top of the mounting plate 11; the support plate 40 is arranged around the periphery of the lens light output assembly 60; and the outer side of the support plate 40 abuts against the inner wall of the lamp housing 70. The support plate 40 provides double protection against twisting. The plurality of second support columns 30 connected to the support plate 40 arranged circumferentially on the top of the mounting plate 11, and the support plate 40 arranged around the periphery of the lens light output assembly 60 and abutting against the inner wall of the lamp housing 70 on the outer side provide a double protection mechanism for the mounting plate 11. On the one hand, the second support column 30 enhances the supporting strength of the top of the mounting plate 11, and works together with the supporting structure (support block 12) at the bottom to form a three-dimensional support network, thereby limiting the displacement and deformation of the mounting plate 11 from multiple dimensions. On the other hand, the support plate 40 further constrains the circumferential rotation of the mounting plate 11 by tightly abutting against the inner wall of the lamp housing 70. This double protection can continuously ensure the flatness of the mounting plate 11 and maintain the optimal working state of the lens light output assembly 60, especially when dealing with complex installation conditions or structural fatigue of the lamp after long-term use.

[0064] The support plate 40 is arranged around the periphery of the lens light-emitting assembly 60, which not only plays a supporting role, but also cleverly utilizes the space around the lens light-emitting assembly 60, avoiding the extra occupation of too much valuable space inside the lamp, making the internal structure of the lamp more compact and reasonable. For large-sized stage lamps and other lamps with strict requirements on space layout, this helps to integrate more functional components within the limited internal space of the lamp housing 70, thereby improving the overall performance and versatility of the lamp.

[0065] Since the support plate 40 is in close contact with the inner wall of the lamp housing 70, the path and area of ​​heat conduction can be increased. During the operation of the lamp, the lens light output assembly 60 and other electronic components will generate heat, and the support plate 40 can quickly transfer the heat to the lamp housing 70, and dissipate the heat with the help of the larger heat dissipation surface area of ​​the lamp housing 70, 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.

[0066] In one embodiment, the support plate 40 is composed of a plurality of support plate elements 41. Designing the support plate 40 as a combination of a plurality of support plate elements 41 greatly simplifies the assembly process of the lamp. In the lamp production workshop, workers can pre-treat each support plate element 41 separately, such as surface cleaning, installation of auxiliary accessories, etc., and then precisely splice and assemble these elements into the interior of the lamp. Compared with the large integrated support plate 40, this modular installation method reduces the requirements for installation space, and workers can operate more flexibly inside the limited lamp housing 70, reducing the risk of collision during installation and improving installation efficiency. When the lamp is used for a long time, if the support plate 40 is damaged or the performance deteriorates, the support plate 40 composed of multiple elements is convenient for quickly locating the source of the problem. Maintenance personnel only need to check each component one by one to accurately find the faulty component, without spending a lot of time troubleshooting the overall structure as with the integrated support plate 40. Moreover, when replacing damaged components, only the corresponding single or a few components need to be removed without disassembling the entire support plate 40, which greatly shortens the maintenance time, reduces the maintenance cost, ensures that the lamp can return to normal operation as soon as possible, and reduces the impact on performances and lighting operations.

[0067] In one embodiment, the bottom of the lamp housing 70 is fixedly connected to the base 10 ; and a light-transmitting plate 71 is disposed on the top of the lamp housing 70 .

[0068] In one embodiment, a wire passing post 50 is provided between the mounting plate 11 and the base 10; and a wire passing hole 51 is provided on the wire passing post 50. By providing the wire passing post 50, the wiring inside the lamp head 1 assembly can be facilitated, and the installation process can be simplified.

[0069] In one embodiment, the number of the support blocks 12 is the same as that of the first support columns 20; the support blocks 12 are fixedly connected to the first support columns 20. The support blocks 12 and the first support columns 20 work together to form a stable support network, which can more evenly disperse the weight of the mounting plate 11 and the upper components, effectively reduce local stress concentration, and reduce the possibility of deformation or twisting of the mounting plate 11 due to uneven force, thereby providing a more stable installation foundation for the lens light output component 60 to ensure the consistency and stability of its light output effect. Since the support block 12 is fixedly connected to the first support column 20, during the installation process, the two can be positioned and installed as a whole, which helps to improve the accuracy and repeatability of the installation. When installing, the worker only needs to connect this overall structure with the mounting plate 11 and the lamp housing 70 according to the established position and method, so as to ensure the position accuracy of the support structure, thereby ensuring that the installation position of the lens light output component 60 is accurate and correct, and improving the optical performance and overall quality of the lamp. When the lamp is subjected to external forces, such as vibration, collision, etc., the fixed connection between the support block 12 and the first support column 20 can more effectively transmit and disperse the external forces between the two. The support block 12 transmits the external force to the first support column 20, and the first support column 20 evenly distributes the force to the mounting plate 11 and the lamp housing 70. Through this reasonable force transmission path, the ability of the overall structure of the lamp to resist external forces is improved, the risk of damage to the lamp due to external impact is reduced, and the service life of the lamp is extended.

[0070] In one embodiment, the lens includes a plurality of first lenses 61 connected to the top of a lens holder 63; in one embodiment, the lens includes a plurality of first lenses 61 and second lenses 62; the number of the first lenses 61 and the second lenses 62 is the same and they are arranged one by one in the mounting groove of the lens holder 63.

[0071] like Figure 3 As shown, in one embodiment, the support block 12 is connected to the first support column 20 by a screw 14. The support block 12 and the first support column 20 are connected by a single screw 14, which greatly simplifies the assembly process. On the production line of lamps, workers only need a screwdriver to quickly and accurately position and fix the support block 12 to the first support column 20. Compared with complex connection methods, it is not only easy to operate, but also can effectively avoid the accumulation of installation errors caused by too many connectors. At the same time, the screw 14 connection provides sufficient fastening force to ensure that the support block 12 and the first support column 20 will not easily loosen or move during the use of the lamp, laying a solid foundation for the stability of the entire support structure. For example, when mass-producing lamps, this simple and efficient connection method can greatly shorten the assembly time of a single lamp, improve production efficiency, and reduce labor costs.

[0072] In one embodiment, the support block 12 is formed with a limiting protrusion 13 that cooperates with the side of the mounting plate 11 to limit the rotation of the support block 12. The limiting protrusion 13 on the support block 12 is tightly matched with the side of the mounting plate 11, and is fixedly combined with a single screw 14, which fundamentally limits its rotational freedom and greatly simplifies the installation structure; when the lamp encounters external force impact, such as vibration during transportation, shaking caused by collision with other equipment on the stage, etc., the torsional force transmitted from the mounting plate 11 to the support block 12 will be effectively blocked by the limiting protrusion 13. This allows the support block 12 to always maintain a stable supporting posture, thereby ensuring that the mounting plate 11 will not be twisted due to the accidental rotation of the support block 12, providing a reliable installation platform for the lens light output component 60, and maintaining the accuracy and stability of light output.

[0073] It should be noted that the torsion in the present invention includes torsion at the connection between the mounting plate 11 and the first support column 20; it also includes torsion / deformation of the mounting plate 11 itself under force;

[0074] Structural coordination principle: The second support column 30 and the support plate 40 jointly construct a structural system that works in coordination. As a vertical support member, the second support column 30 expands the vertical function of the support block 12, and the support plate 40 disperses the force to the lamp housing 70 by virtue of its large-area contact with the inner wall of the lamp housing 70, while using its own annular structure to constrain the deformation of the mounting plate 11. The support block 12 and the support plate 40 work in coordination to ensure that the plane of the mounting plate 11 always remains flat and maintain the stable installation state of the lens light output assembly 60.

[0075] like Figure 8 As shown, in one embodiment, three or four splicing plates 6311 are evenly distributed on the periphery of the column 6310; the column 6310 serves as the core support structure of the bracket unit 631, providing a stable vertical support force for the entire bracket. It bears the weight of the lens and the splicing plate 6311, ensuring that the bracket will not tilt or shake in various usage scenarios of the lamp, ensuring the stability of the lens position, and thus ensuring the accuracy of the emitted light beam;

[0076] The middle part of the top surface of the splicing plate 6311 is convexly formed with a partition 6312 extending along the top surface; the top surfaces on both sides of the partition 6312 constitute support surfaces 6313 for supporting the lens; the partition 6312 plays a role of separation and positioning, clarifies the placement of the lens on the support surface 6313, prevents the lens from shifting in the horizontal direction, ensures that the lens accurately docks with the beam path, and effectively improves the controllability of lighting and stage effects. The support surfaces 6313 on both sides of the partition 6312 provide direct bearing support for the lens, contact with the lens over a large area, disperse pressure, reduce the risk of local compression deformation of the lens, ensure that the optical performance of the lens is not damaged, and extend the service life of the lens.

[0077] The splicing plate 6311 is formed with a splicing portion at the far end away from the column 6310. The split structure is adopted and the traditional integrated lens holder is abandoned, so as to avoid 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 instead uses a plurality of relatively simple and small molds to make the bracket unit 631, the mold opening cost is greatly reduced, especially for large-size lamp projects, the cost advantage is more significant. The problem of poor consistency of large-size lens holders is solved. When the integrated structure is used to produce large-size brackets, it is difficult to ensure the consistency of the lens support height everywhere due to the difficulty of the process. The split structure decomposes the large size into multiple small units for splicing, and uses the edge of the lens to limit the top height of the bracket unit 631, thereby ensuring the consistency of the bracket height.

[0078] In one embodiment, three splicing plates 6311 are evenly distributed on the periphery of the column 6310; the layout of the three splicing plates 6311 lays the foundation for the subsequent formation of a hexagonal lens mounting portion 630, adapts to the hexagonal lens structure, realizes a tight and stable splicing combination, optimizes space utilization, and meets the requirements of the optical design of the lamp for the lens layout. The hexagonal lens design is perfectly adapted to the hexagonal mounting portion spliced ​​by multiple bracket units 631. The edge of the lens is used to limit the height of the top of the bracket unit 631. This self-limiting mechanism cleverly solves the problem of adjusting the height consistency of the bracket unit 631. In the process of locking the lens, the lens automatically unifies the height of the multiple connected bracket units 631, without the need for complex additional leveling procedures, greatly improving the lens installation accuracy, effectively ensuring the uniformity and accuracy of the lamp's output light beam, and meeting the strict requirements of professional stage lighting and searchlights for high-quality light beam output.

[0079] In one embodiment, four splicing plates 6311 are evenly distributed on the periphery of the column 6310; the layout of the four splicing plates 6311 lays the foundation for the subsequent formation of a quadrilateral lens mounting portion 630, adapts to the quadrilateral lens structure, realizes a tight and stable splicing combination, optimizes space utilization, and meets the requirements of the optical design of the lamp for the lens layout.

[0080] In one embodiment, the splicing portion includes a stop plate 6314 extending outward from the far end of the splicing plate 6311 away from the column 6310; the thickness of the stop plate 6314 is half the thickness of the splicing plate 6311. The stop plate 6314 is formed by extending outward from the far end of the splicing plate 6311, and it plays a precise positioning and blocking role in the splicing process of multiple bracket units 631. When adjacent bracket units 631 are spliced, the stop plates 6314 contact each other, which can quickly determine the relative positions of the two units in this direction, effectively avoiding problems such as misalignment and offset during splicing, greatly improving the efficiency of splicing assembly, reducing assembly time, and significantly improving production efficiency for large-scale lamp production.

[0081] As a part of the splicing part, the stop plate 6314 has a thickness of half that of the splicing plate 6311. When adjacent bracket units 631 are spliced, the stop plates 6314 are butted against each other, and the thickness of the two stop plates 6314 after butting against each other is exactly the same as the thickness of the splicing plate 6311. This not only ensures that the stop plate 6314 has sufficient structural strength to achieve a precise stop function, but also effectively avoids occupying too much space due to being too thick, 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 greatly improving the overall integration of the lamp.

[0082] The structure of the stop plate 6314 allows adjacent stop plates 6314 to be limited in position by abutment when spliced, which can prevent the stop plates 6314 from moving in the plane, such as misalignment and offset, but can allow the stop plates 6314 to have a slight movement along the axis of the column 6310, which provides conditions for balancing the height consistency of the top of the bracket unit 631. The height of the top of the bracket unit 631 is limited by the edge of the lens, which solves the problem of adjusting the height consistency of the bracket unit 631. In the process of locking the lens, the lens automatically unifies the height of multiple connected bracket units 631, without the need for complex additional leveling procedures, greatly improving the lens installation accuracy.

[0083] In one embodiment, the stop plate 6314 is connected to one of the support surfaces 6313; the direction from the support surface 6313 connected to the stop plate 6314 to the other support surface 6313 on the splicing plate 6311 is a first direction, and the first directions of the multiple splicing plates 6311 are in the same direction, for example, the multiple first directions constitute a clockwise direction or a counterclockwise direction. The first directions of the multiple splicing plates 6311 are in the same direction. This design makes the entire lens mounting frame have clear directionality and regularity. In the production and assembly process, workers can quickly identify and arrange the bracket units 631 according to the unified direction, reducing the difficulty of operation.

[0084] In one embodiment, the first directions of the plurality of splicing plates 6311 may also be different. This structure increases the types of bracket units 631, but they can still be assembled to form a lens holder.

[0085] like Fig. 9As shown, in one embodiment, a bottom plate 6315 is provided at the bottom of the column 6310; the bottom plate 6315 is connected to the splicing plate 6311; the bottom plate 6315 extends beyond the side of the splicing plate 6311 to form a stabilizing plate 6317. The bottom plate 6315 is connected to the splicing plate 6311, providing a more stable support foundation for the column 6310 and the entire bracket unit 631, and increasing the overall stability of the structure. During the long-term use of the lamp, it can better withstand external forces in all directions, reduce shaking and deformation, and extend its service life; the stabilizing plate 6317 increases the contact area, making the installation stability of the bracket unit 631 stronger;

[0086] In one embodiment, a reinforcing plate 6318 is connected between the outer periphery of the column 6310 and the bottom plate 6315. The reinforcing plate 6318 is equivalent to a reinforcing rib, and the reinforcing plate 6318 can provide additional support between the column 6310 and the bottom plate 6315, making the connection between the two more stable, enhancing the overall structural strength, ensuring the linearity of the column 6310 when subjected to force, and thus improving the stability and reliability of the lens installation.

[0087] like Fig. 9 As shown, in one embodiment, a fixing seat 6316 is provided at the bottom of the bottom plate 6315; the fixing seat 6316 is located at the bottom of the far end of the splicing plate 6311 away from the column 6310. The fixing seat 6316 increases the contact area and connection points between the bottom plate 6315 and the external mounting structure, making the installation stability of the bracket unit 631 stronger; the fixing seat 6316 can be a fixing seat 6316 formed by a protrusion at the bottom of the bottom plate 6315 for connecting the screw 893, and a connecting hole is provided on the fixing seat 6316, or it can be a connecting hole set on the bottom plate 6315 for connecting the screw 893;

[0088] like Fig.10 As shown, in one embodiment, it also includes a closing unit 632 arranged on the periphery for forming a closed lens mounting portion 630; the closing unit 632 includes a second column 6320; two second splicing plates 6321 are arranged on the periphery of the second column 6320; the closing unit 632 is used to cooperate with the bracket unit 631 to form more lens mounting portions 630, for example, when the bracket unit 631 includes three splicing plates 6311, the outer ring will have an unclosed structure after splicing, and the middle part of the lens holder after splicing will have multiple complete lens mounting portions 630, while the unclosed space on the periphery will be wasted, and the unclosed space can be effectively utilized to form the lens mounting portion 630 by adding the closing unit 632; when the angle between the two second splicing plates 6321 is 120°, it can effectively cooperate with the bracket unit 631; in one embodiment, when the bracket unit 631 includes four splicing plates 6311, the angle between the two second splicing plates 6321 of the closing unit 632 is set to 90°, so that it can effectively cooperate with the bracket unit 631;

[0089] A second partition plate 6322 is formed by a protrusion in the middle of the top surface of the second splicing plate 6321; the top surfaces on both sides of the second partition plate 6322 constitute a second supporting surface 6323 for supporting the lens; a splicing portion is formed at the far end of the second splicing plate 6321 away from the column 6310; the splicing portion includes a second stop plate 6324 extending outward from the far end of the second splicing plate 6321 away from the second column 6320; the thickness of the second stop plate 6324 is half the thickness of the second splicing plate 6321. The second stop plate 6324 is connected to one of the second supporting surfaces 6323; a second bottom plate 6325 is provided at the bottom of the second column 6320; the second bottom plate 6325 is connected to the second splicing plate 6321; the second bottom plate 6325 extends beyond the side of the second splicing plate 6321 to form a second stabilizing plate 6326; a second reinforcing plate 6327 is connected between the outer periphery of the second column 6320 and the second bottom plate 6325; other beneficial effects of each structure of the closed unit 632 are the same as those of the bracket unit 631 and are not repeated here.

[0090] like Figure 11-12 As shown, in one embodiment, a limiting member 633 for abutting against the corner of the lens is provided on the second column 6320 ; a stabilizing block 6328 cooperating with the limiting member 633 is provided on the side of the second column 6320 away from the second splicing plate 6321 .

[0091] In one embodiment, the bottom of the stopper 633 is provided with an arc-shaped abutting surface 6331 that abuts against the surface of the lens. This overcomes the problem that the traditional pressing plate is inconvenient to disassemble and cannot flexibly operate a single lens, and achieves simple and effective fixation and release of a single lens. The arc-shaped abutting surface 6331 gently and tightly fits the corners of the lens, which can not only firmly fix the lens to prevent it from falling out, but also avoid damaging the lens surface;

[0092] In one embodiment, a positioning plate 6332 is provided at the bottom of the limiting member 633 ; the thickness of the positioning plate 6332 is the same as the thickness of the partition plate 6312 ; and the positioning plate 6332 is arranged between adjacent lenses. The main function of the positioning plate 6332 is to be inserted between the lenses and limit the position of the lenses from the corners of the lenses; in one embodiment, three splicing plates 6311 are evenly distributed on the periphery of the column 6310; the lens mounting portion 630 is hexagonal, and the limiting member 633 contacts the corners of the three lenses at the same time, so as to ensure the consistency of the spacing between the multiple lenses; since the limiting member 633 limits the position of the lens at one point, it is difficult for a single limiting member 633 to effectively ensure the accuracy of the lens installation position, so the precise installation of the lens position is the effect of the joint action of all the limiting members 633 after they are installed in place, that is, after all the limiting members 633 are installed, the spacing between the lenses is automatically adjusted, which has the advantage that the position of the lens does not need to be adjusted separately, but is directly achieved by installation and fixing, which effectively saves adjustment time and improves efficiency; on the other hand, the positioning plate 6332 can also be used for rapid installation on the column 6310, because the positioning plate 6332 is clamped with the gap between the lens, it is convenient for workers to quickly operate when installing the limiting member 633, reducing alignment time and improving efficiency;

[0093] In one embodiment, a first through hole 6333 is provided in the middle of the stopper 633; ​​the stopper 633 is fixedly connected to the column 6310 after the fixing screw 6334 passes through the first through hole 6333. The fixing screw 6334, as a fastening element commonly used in mechanical connection, has a strong axial tensile force. By passing through the through hole of the stopper 633 and screwing into the column 6310, a stable connection relationship can be established between the stopper 633 and the column 6310. When the lamp needs to be maintained, such as replacing a damaged lens, inspecting the stopper 633 or the column 6310, etc., the connection method of the stopper 633 is very convenient, and there is no need to remove the entire pressure plate for maintenance as in the traditional structure.

[0094] In one embodiment, a gasket 6335 is sleeved on the fixing screw 6334; a balance block 6337 sleeved on the fixing screw 6334 is provided below the gasket 6335; the gasket 6335 and the balance block 6337 cooperate to balance the pressure of the stopper 633 on multiple lenses; in this structure, the gasket 6335 and the rubber balance block 6337 work together to ensure the reasonable distribution of pressure from different levels. The gasket 6335 usually has a certain hardness and flatness. It is located at the top and first bears the initial pressure of the head of the fixing screw 6334. With its large contact area, it initially disperses the concentrated tightening force to avoid excessive single-point pressure of the fixing screw 6334 causing damage to the lower parts. The rubber balance block 6337, with its excellent elastic deformation ability, can further accurately sense and balance the pressure of the limit piece 633 on multiple lens corners, and finely adjust its own shape according to the actual force conditions to ensure that the pressure on the lens is uniform and gentle. This double protection mechanism greatly reduces the risk of damage to the lens due to uneven force, effectively maintains the optical integrity of the lens, extends its service life, and ensures the stability and durability of the lighting effect of the lamp.

[0095] In one embodiment, a receiving groove 6336 is provided at the top of the position-limiting member 633; ​​a balancing block 6337 is provided in the receiving groove 6336; the size of the balancing block 6337 is larger than the size of the end of the fixing screw 6334; the balancing block 6337 abuts against the receiving groove 6336 to balance the pressure of the position-limiting member 633 on the multiple lenses; the receiving groove 6336 provides a dedicated placement space for the balancing block 6337, so that it can be accurately positioned in the key pressure-applying area at the top of the position-limiting member 633. Since the size of the balancing block 6337 is larger than the end of the fixing screw 6334, the contact area between the balancing block 633 and the top surface of the position-limiting member 633 is larger, and the pressure applied by the position-limiting member 633 to the multiple lens corners can be more comprehensively and evenly received. When the lamp is disturbed by various external forces during operation or the pressure fluctuates due to slight changes in its structure, the balance block 6337 can adjust its shape in the receiving groove 6336 by itself with its good elasticity or flexibility (depending on its material), and evenly distribute the pressure to each lens contact point, effectively avoiding excessive force on the lens, effectively ensuring the structural integrity and optical performance stability of the lens, extending the service life of the lens, and laying a solid foundation for the continuous and stable lighting of the lamp. The setting of the receiving groove 6336 also helps to reduce the height of the fixing parts and save internal space.

[0096] In one embodiment, the bottom of the stopper 633 is provided with a padding portion 6338 that cooperates with the column 6310. The padding portion 6338 ensures effective contact between the stopper 633 and the lens;

[0097] like Fig.13As shown, in one embodiment, a light shield 80 is provided between the light emitting unit 90 and the lens light emitting assembly 60; the light shield 80 is provided with a light hole 81 that allows the light emitted by the light emitting unit 90 to pass through; the light shield 80 is connected to a driving assembly 84 that controls its movement to block light; the driving assembly 84 is driven by an energy storage module 85. The arrangement structure of the light shield 80 fully considers the internal space layout of the lamp. The space between the light emitting unit 90 and the light emitting assembly is reasonably utilized, which does not affect the normal light emission of the lamp, and leaves enough space for the installation and operation of the light shield 80. Whether it is a small portable stage light or a large outdoor searchlight, the size and position can be flexibly adjusted according to the characteristics of its internal structure to achieve the best adaptation and improve the overall space utilization of the lamp. Compared with the traditional sunshade, it will not cause additional interference to the normal light emission of the lamp, and only activates the protection mechanism when the power is off, ensuring that the lamp can perform its lighting function without hindrance during normal use.

[0098] The setting of the energy storage module 85 can realize the automatic control of the driving component 84 when the power is off. Whether it is daily power outage, sudden power outage or manual power off, once the equipment is powered off, the energy storage module 85 can control the driving component 84 to accurately manipulate the movement of the light shielding plate 80. The whole process does not require human intervention, which is efficient and reliable. For example, in the application scenario of outdoor security searchlights, severe weather may cause power supply line failure. At this time, the light shielding plate 80 will automatically adjust its position at the moment of power failure, and the light hole 81 will deviate from the light-emitting unit 90, timely blocking the invasion of the focused sunlight, avoiding damage to the light-emitting unit 90, greatly extending the service life of the lamp, and reducing the high cost and maintenance energy consumption caused by frequent replacement of components. The energy storage module 85 is flexible in design. It can not only use general energy storage components to meet the conventional power supply stability requirements, but also optimize the configuration according to special application scenarios. For example, stage lights used in areas with unstable power supply can be equipped with large-capacity energy storage batteries as energy storage modules 85 to ensure that even if the power is cut off for a long time, the light shield 80 can be operated multiple times to provide long-term protection for the lamp. In another embodiment, a capacitor is used as the energy storage module 85. The advantages of the capacitor's rapid charging and discharging and small size are utilized to achieve immediate protection after power failure without increasing excessive weight and space occupancy, thereby effectively reducing costs and reducing the space occupied by the lamp.

[0099] In one embodiment, the light emitting unit 90 is disposed on the base 10;

[0100] like Fig.15As shown, in one embodiment, the light shielding plate 80 is connected to the base 10 through a third support column 82; the third support column 82 is movably connected to the light shielding plate 80 through a guide support 820; a plurality of third support columns 82 are provided; the light shielding plate 80 is connected to the base 10 through a plurality of third support columns 82, thereby constructing a stable mechanical support structure. Multiple support points are evenly distributed at the bottom of the light shielding plate 80, effectively sharing the weight of the light shielding plate 80 itself and the stress generated during the movement. This allows the light shielding plate 80 to always remain stable during frequent light shielding actions, and will not shake or deviate due to uneven force.

[0101] In one embodiment, the guide support member 820 includes a support portion 821 for supporting the light shielding plate 80; the support portion 821 is provided with a guide portion 822 that cooperates with the guide groove 83 on the light shielding plate 80. The support portion 821 provides vertical support force for the light shielding plate 80, ensuring that the light shielding plate 80 is stably suspended in the vertical direction to avoid sagging due to gravity affecting the light shielding effect. The guide portion 822 thereon closely cooperates with the guide groove 83 of the light shielding plate 80 to strictly constrain the rotation path of the light shielding plate 80. When the driving assembly 84 drives the light shielding plate 80 to rotate, the guide portion 822 guides the light shielding plate 80 to move precisely along a predetermined trajectory, ensuring that the light hole 81 can accurately deviate from or align with the light-emitting unit 90, achieving efficient and reliable switching between light shielding and light transmission, and greatly improving the accuracy of protection.

[0102] In one embodiment, a limiting portion 823 is provided above the guide portion 822 and is located at the top of the light shielding plate 80 to limit the top of the light shielding plate 80. During the operation of the lamp, whether it is daily vibration, bumps during transportation, or external force impact in extreme environments, the limiting portion 823 can effectively prevent the light shielding plate 80 from moving upward from its normal working position due to accidental force.

[0103] In one embodiment, the light blocking plate 80 is circular; three support columns are evenly arranged along the circumference of the light blocking plate 80 .

[0104] In one embodiment, the base 10 is provided with a limiting column 87, which passes through the light shielding plate 80 and cooperates with the limiting groove 86 on the light shielding plate 80 to limit the rotation angle of the light shielding plate 80. The limiting column 87 is used to further limit the rotation angle of the light shielding plate 80.

[0105] like Figure 17-18 As shown in the figure, the multiple inverted cone-shaped structures on the light blocking plate 80 are schematic diagrams of the light beam after the emitted light of the light-emitting unit 90 passes through the light-through hole 81.

[0106] like Figure 13-14As shown, in one embodiment, the driving assembly 84 includes a motor mounting seat 840 mounted on the base 10; a screw motor 841 is provided on the motor mounting seat 840; a screw 842 of the screw motor 841 is provided with a screw sleeve 843; the screw sleeve 843 is connected to a guide column 844; the guide column 844 cooperates with a matching hole on the light shielding plate 80 to drive the rotation of the light shielding plate 80. The screw motor 841 is used as the driving core. When the screw motor 841 is running, the screw sleeve 843 moves linearly along the thread of the screw 842. This transmission method accurately converts the rotational motion of the motor into linear displacement. Compared with some traditional connecting rod transmission or gear transmission, the screw 842 transmission has higher accuracy, almost no backlash phenomenon, and can accurately transmit the tiny motor rotation. When controlling the rotation of the light shielding plate 80, the light shielding plate 80 is accurately positioned to ensure that the relative position between the light hole 81 and the light-emitting unit 90 is accurate and correct, effectively blocking the focused light of the sunlight, and greatly improving the accuracy of protection. The screw motor 841 operates smoothly and outputs power evenly and continuously. During the entire use cycle of the lamp, whether it is frequently switched between power-off and power-on to switch the light shielding state, or the protective action is started for the first time after a long period of static, the screw motor 841 can stably drive the light shielding plate 80.

[0107] In one embodiment, the screw sleeve 843 is provided with a connecting seat 845; the connecting seat 845 is fixedly connected with a guide column 844; the screw 842 is provided with a guide shaft 846 parallel to the screw 842 on the side; the guide shaft 846 is slidably connected with the connecting seat 845. The guide shaft 846 arranged parallel to the screw 842 provides a reliable linear motion reference for the connecting seat 845 and the components connected thereto. When the screw motor 841 operates to drive the screw sleeve 843 to move, the connecting seat 845 can only slide smoothly along the direction defined by the guide shaft 846 due to the sliding connection with the guide shaft 846, thereby avoiding the lateral deviation or twisting of the screw sleeve 843 when it is subjected to force. The guide shaft 846 cooperates with the screw 842 to form a coordinated stabilization mechanism. The screw 842 is responsible for providing precise axial driving force, while the guide shaft 846 is responsible for constraining lateral displacement.
