Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and more specifically, to an effect module with a clamping reset component, an optical system, and a stage light. Background Technology

[0002] Effect modules in stage lighting equipment achieve diverse lighting effects through switchable effect panels, and the switching of effect panels is mainly accomplished by drive and reset components. When the motor in the drive component is running, it drives the swing arm to rotate via pulleys or gear transmission, causing effect panels such as atomizing sheets and prisms to cut into the light path aperture to intercept the light beam; after power is cut off, elastic elements (such as torsion springs and tension springs) drive the effect panels to reset and exit the light path through deformation potential energy. In the existing technology, the connection methods between the elastic elements and the motor shaft are mainly divided into two categories: one is to use a flange connection structure, in which one end of the elastic element is fixed to the motor shaft and the other end is anchored to the base plate, and the reset is achieved by the torque generated by elastic deformation; the other is to directly fix one end of the elastic element to the drive pulley to transmit the reset torque.

[0003] However, the above structure has the following technical defects: the flange connection not only occupies a large installation space, but also requires additional screws to hold the motor shaft in place. After long-term use, the flange and the motor shaft are prone to relative slippage due to vibration, resulting in a deviation in the reset angle; one end of the elastic element is directly fixed to the drive pulley, which requires a pulley of a sufficiently large size to provide enough installation space to connect with the elastic element. Utility Model Content

[0004] To overcome at least one of the defects of the prior art, this utility model provides an effect module, optical system, and stage light with a clamping reset component. The clamping base is used to fix and install the elastic element, reducing installation space and adapting to drive mechanisms of more sizes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an effect module, an optical system, and a stage light with a clamping reset component. The clamping reset component includes a substrate with a light-transmitting hole, a bracket pivotally connected to the substrate, an effect piece mounted on the bracket, and a driving component that drives the bracket to rotate, thereby causing the effect piece to cover the light-transmitting hole. It also includes an elastic element and a clamping seat. The clamping seat clamps and fixes a motor shaft in the driving component via two clamping arms. One end of the elastic element is fixedly connected to the clamping seat, and the other end is directly or indirectly fixedly connected to the substrate, and applies a reset force to the bracket to rotate the effect piece and open the light-transmitting hole.

[0006] The clamping seat is connected to the motor shaft in the drive assembly using a clamping and fixing method, which can accommodate motor shafts of more sizes. When the motor stops outputting driving force, the motor shaft can rotate freely. At this time, under the action of the elastic element, the clamping seat drives the motor shaft to rotate, thereby driving the bracket to rotate the effect piece to open the light-transmitting hole and complete the reset of the effect piece. Compared with the existing solution of using flanges to install the elastic element, which requires selecting different sized flanges according to the size of each motor shaft and relying solely on screws screwed into the outside of the flange to hold the shaft in place, this method may loosen and fail after long-term use. The clamping seat can tightly hug the motor shaft, ensuring a stable connection between the two. At the same time, compared with the installation space requirements of flanges, the installation space of the clamping seat is significantly reduced. Furthermore, with one end of the elastic element fixed to the pulley, the clamping seat is not limited by the size of the pulley, making installation more flexible.

[0007] Furthermore, the two clamping arms together form a locking hole for clamping the motor shaft; the clamping base also includes a locking element for adjusting the distance between the two clamping arms. By adjusting the size of the locking hole using the locking element, the clamping base and the motor shaft can be clamped and loosened, facilitating operation.

[0008] Furthermore, the motor shaft is connected to a drive wheel that drives the bracket to rotate. The clamping seat extends a connecting section away from the motor shaft. The distance between the location where the connecting section connects to the elastic element and the motor shaft is greater than the radius of the drive wheel. By providing the connecting section, the lever arm of the force exerted by the elastic element on the motor shaft is effectively extended. Therefore, an elastic element with relatively low elasticity can be used to achieve the repositioning of the effect piece.

[0009] Furthermore, the distance between the connection point of the connecting segment and the elastic element and the motor shaft is between 8mm and 15mm. This arrangement ensures that the lever arm of the force exerted by the elastic element on the motor shaft is long enough to allow the elastic element to reset with a small amount of elastic force, while also preventing the connecting segment from extending too far and causing spatial interference with surrounding components.

[0010] Furthermore, the end of the clamping arm connected to the connecting section is provided with a notch to reduce its own bending stiffness. This facilitates the elastic deformation of the clamping arm to adjust the clamping force of the clamping seat on the motor shaft.

[0011] Furthermore, the elastic element is a torsion spring, which is sleeved on the outer periphery of the motor shaft, and the clamping seat is located on the side of the torsion spring away from the motor housing. Choosing the torsion spring allows for full utilization of the axial space of the motor shaft, making the structure of the effect module more compact.

[0012] Furthermore, the thickness of the clamping seat is less than 5mm. This ensures that the clamping seat has a certain height to securely clamp the motor shaft without occupying excessive axial space.

[0013] Furthermore, the effect sheet is at least one of a fogging sheet, a prism, a pattern sheet, or a color sheet. When the effect sheet is a fogging sheet, the light beam passing through it undergoes diffuse reflection processing, making the brightness and color of the light spot more uniform; when the effect sheet is a prism, the light beam passing through it undergoes beam splitting processing, correspondingly forming multiple light spots; when the effect sheet is a pattern sheet, the light beam passing through it is intercepted and projected onto the target plane with a light spot having a specific pattern effect; when the effect sheet is a color sheet, the light beam passing through it is color-rendered, causing it to project a light spot of a specific color onto the target plane.

[0014] Furthermore, one end of the bracket has a mounting hole for mounting the effect piece, and the other end is connected to the drive assembly for transmission; under the drive of the drive assembly, the bracket causes the effect piece to swing. Compared with disc-type effect modules that drive the effect piece to switch working positions and reset by rotation, this solution can save more installation space.

[0015] This invention also provides an optical system, including a light source for generating a light beam and a light-emitting lens. Any of the aforementioned effect modules is located between the light source and the light-emitting lens. When the effect sheet covers the light-transmitting aperture, the effect sheet intercepts the light beam to produce a specific effect, which is ultimately projected through the light-emitting lens. By mounting the elastic element using the clamping base, the installation space can be significantly reduced, thereby making the layout of the effect module and the entire optical path structure more compact.

[0016] This utility model also provides a stage light, including a lamp head with a light outlet and a support base for supporting the rotation of the lamp head. The optical system is installed inside the lamp head, and the light source is installed at the end of the lamp head away from the light outlet. The light-emitting lens covers the light outlet. When disassembly and assembly are required, since the clamping base and the motor shaft are installed and fixed by clamping, maintenance can be completed without disassembling and assembling layers during the disassembly and assembly process. The structure is simple and easy to operate, facilitating the maintenance of the effects module. Attached Figure Description

[0023] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known components and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, an effects module 100 with a clamping reset assembly, an optical system, and a stage light are disclosed. The effects module 100 with a clamping reset assembly includes a substrate 110 with a light-transmitting hole 111, a bracket 120 pivotally connected to the substrate 110, an effects panel 130 mounted on the bracket 120, and a drive assembly that drives the bracket 120 to rotate, thereby causing the effects panel 130 to cover the light-transmitting hole 111. It also includes an elastic element 140 and a clamping seat 150. The clamping seat 150 clamps and fixes a motor shaft 161 in the drive assembly through two clamping arms 151. One end of the elastic element 140 is fixedly connected to the clamping seat 150, and the other end is directly or indirectly fixedly connected to the substrate 110, and applies a reset force to the bracket 120 to rotate the effects panel 130 to open the light-transmitting hole 111.

[0025] The clamping base 150 is connected to the motor shaft 161 in the drive assembly by clamping and fixing, and can accommodate more sizes of the motor shaft 161. When the motor stops outputting driving force, the motor shaft 161 can rotate freely. At this time, under the action of the elastic member 140, the clamping base 150 drives the motor shaft 161 to rotate, and drives the bracket 120 to rotate the effect piece 130 to open the light hole 111, thus completing the reset of the effect piece 130. Compared to existing solutions that use flanges to install the elastic element 140, which require selecting flanges of different sizes based on the dimensions of each motor shaft 161 and rely solely on screws screwed into the outside of the flange to hold the shaft in place (potential for loosening and failure over time), the clamping seat 150 tightly encircles the motor shaft 161, ensuring a stable connection. Furthermore, the clamping seat 150 significantly reduces the installation space required by flanges. Moreover, by fixing one end of the elastic element 140 to the pulley, the clamping seat 150 is not limited by the pulley's size, allowing for more flexible installation. The clamping seat 150 and the elastic element 140 form a clamping reset assembly.

[0026] Preferably, a rubber mat is provided between the clamping arm 151 and the motor shaft 161 to further secure the connection between the two and prevent accidental loosening.

[0027] Preferably, the effect piece 130 is in a working state when it covers the light-transmitting hole 111, and in a reset state when it is not. The bracket 120 switches the effect piece 130 between the working and reset states by swinging. It also includes a limiting post 180 fixedly connected to the substrate 110 to limit the swing angle of the bracket 120 and prevent it from swinging too much and interfering with other components. The elastic member 140 is indirectly connected to the substrate 110 through a fixing post 170.

[0028] Preferably, the material of the clamping base 150 can be selected from aluminum alloy or plastic materials as needed.

[0029] In a preferred embodiment of this invention, the two clamping arms 151 together form a locking hole 152 for clamping the motor shaft 161; the clamping base 150 also includes a locking member 153 for adjusting the distance between the two clamping arms 151. By adjusting the size of the locking hole 152 using the locking member 153, the clamping base 150 and the motor shaft 161 can be clamped, fixed, or released, facilitating operation.

[0030] Preferably, the locking member 153 is a locking screw, and the two clamping arms 151 are provided with locking holes 152 at the ends away from the locking holes 152. By tightening the locking screw, the distance between the two clamping arms 151 can be easily adjusted.

[0031] In a preferred embodiment of this invention, the motor shaft 161 is connected to a drive wheel 162 that drives the bracket 120 to rotate. The clamping seat 150 extends a connecting section 154 away from the motor shaft 161. The distance between the connecting section 154, where it connects to the elastic member 140, and the motor shaft 161 is greater than the radius of the drive wheel 162. By providing the connecting section 154, the lever arm of the force exerted by the elastic member 140 on the motor shaft 161 is effectively extended. Therefore, the elastic member 140 with relatively small elasticity can be used to achieve the repositioning of the effect piece 130.

[0032] Preferably, the drive mechanism further includes a driven wheel 163 fixedly connected to the bracket 120 and a synchronous belt 164 that simultaneously connects the drive wheel 162 and the driven wheel 163; the motor housing 165 is located on the reverse side of the base plate 110, the motor shaft 161 passes through the base plate 110 and extends outward, and along a direction away from the front side of the base plate 110, the drive wheel 162, the elastic element 140 and the clamping seat 150 are sequentially sleeved on the motor shaft 161, and the clamping seat 150 can prevent the tension spring from disengaging from the motor shaft 161.

[0033] In a preferred embodiment of this invention, the distance between the connection point of the connecting segment 154 and the elastic element 140 and the motor shaft 161 is between 8mm and 15mm. This arrangement ensures that the lever arm of the force exerted by the elastic element 140 on the motor shaft 161 is long enough to allow the elastic element 140 to achieve reset with a small elastic force, while also preventing the connecting segment 154 from extending too far and causing spatial interference with surrounding components.

[0034] Preferably, the connecting segment 154 extends in a direction parallel to the clamping arm 151.

[0035] like Figure 2 As shown, in a preferred embodiment of this utility model, one end of the clamping arm 151 connected to the connecting section 154 is provided with a notch 155 to reduce its own bending stiffness. This facilitates the elastic deformation of the clamping arm 151 to adjust the force with which the clamping seat 150 clamps the motor shaft 161.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, in a preferred embodiment of this utility model, the elastic element 140 is a torsion spring, which is sleeved on the outer periphery of the motor shaft 161, and the clamping seat 150 is located on the other side of the torsion spring away from the motor housing 165. Choosing the torsion spring can make full use of the axial space of the motor shaft 161, making the structure of the effect module 100 more compact.

[0037] In other embodiments of this utility model, the elastic element 140 may be selected as a tension spring.

[0038] In a preferred embodiment of this invention, the thickness of the clamping seat 150 is less than 5mm. This ensures that the clamping seat 150 has a certain height to securely clamp the motor shaft 161 without occupying excessive axial space.

[0039] In a preferred embodiment of this utility model, the effect sheet 130 is at least one of a fogging sheet, a prism, a pattern sheet, or a color sheet. When the effect sheet 130 is a fogging sheet, it diffuses the light beam passing through it, making the brightness and color of the light spot more uniform; when the effect sheet 130 is a prism, it splits the light beam passing through it, forming multiple light spots accordingly; when the effect sheet 130 is a pattern sheet, it intercepts the light beam passing through it and projects a light spot with a specific pattern effect onto the target plane; when the effect sheet 130 is a color sheet, it renders the light beam passing through it with color, causing it to project a light spot of a specific color onto the target plane.

[0040] Preferably, when the effect piece 130 is a frosting piece or a prism, the bracket 120 drives the effect piece 130 to swing and cover or open the light-transmitting hole 111. When the effect piece 130 is a pattern piece or a color piece, the bracket 120 has a disc structure, and the position of the effect piece is switched by rotation.

[0041] In a preferred embodiment of this utility model, one end of the bracket 120 has a mounting hole 121 for mounting the effect piece 130, and the other end is connected to the driving assembly for transmission; under the drive of the driving assembly, the bracket 120 drives the effect piece 130 to swing. Compared with the disc-type effect module 100 that drives the effect piece 130 to switch working positions and reset by rotation, this solution can save more installation space.

[0042] Preferably, at least two of the brackets 120 are stacked and mounted in a direction away from the substrate 110, pivotally connected to the same fixed post 170, and driven by two sets of the drive components respectively.

[0043] This invention also provides an optical system, including a light source 200 for generating a light beam and a light-emitting lens 300. Any of the aforementioned effect modules 100 is located between the light source 200 and the light-emitting lens 300. When the effect plate 130 covers the light-transmitting aperture 111, the effect plate 130 intercepts the light beam to produce a specific effect, which is ultimately projected through the light-emitting lens 300. By mounting the elastic member 140 using the clamping base 150, the installation space can be significantly reduced, thereby making the layout of the effect module 100 and the entire optical path structure more compact.

[0044] like Figure 3 and Figure 4 As shown, this utility model also provides a stage light, including a lamp head 400 with a light outlet 410 and a support base 500 supporting the rotation of the lamp head 400. The optical system is installed inside the lamp head 400, and the light source 200 is installed at the end of the lamp head 400 away from the light outlet 410. The light-emitting lens 300 covers the light outlet 410. When disassembly and assembly are required, since the clamping base 150 and the motor shaft 161 are installed and fixed by clamping, maintenance can be completed without disassembling and assembling layers during the disassembly and assembly process. The structure is simple and easy to operate, facilitating the maintenance of the effect module 100.

[0045] Preferably, the support base 500 includes a housing 510 and a support arm pivotally connected above the housing 510, the support arm being used to pivotally connect the lamp head 400, thereby allowing the lamp head 400 to rotate relative to the housing 510 about at least two dimensions.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
