Description

Technical Field

[0001] This application relates to the technical field of stage lighting equipment, and in particular to a stage lighting fixture. Background Technology

[0002] Stage lighting fixtures are widely used in stage performances. They can enrich the effects of stage performances by changing the color of light, the type of light beam, and the position of the light.

[0003] In order to enable stage lighting to produce different lighting effects, traditional techniques usually involve setting different types of light sources on the stage lighting fixtures. However, this method increases the manufacturing cost of the stage lighting fixtures. Utility Model Content

[0004] Therefore, it is necessary to provide a stage lighting fixture that addresses the problem of increasing manufacturing costs by requiring different types of light sources to produce different lighting effects in traditional stage lighting fixtures.

[0005] The technical solution is as follows:

[0006] One embodiment provides a stage lighting fixture, including:

[0007] Installation organization;

[0008] A first light-emitting component, wherein at least two of the first light-emitting components are provided and arranged circumferentially along the mounting mechanism;

[0009] A light-changing element is rotatably mounted on the mounting mechanism. The light-changing element has at least two first light-transmitting parts and at least two light-splitting parts. The first light-transmitting parts are arranged in a one-to-one correspondence with the first light-emitting components. All the first light-transmitting parts are arranged along the circumference of the light-changing element. A light-splitting part is provided between every two adjacent first light-transmitting parts.

[0010] Specifically, when the light-changing element is rotated to the first position, the position of the first light-emitting component corresponds to the position of the first light-transmitting part; when the light-changing element is rotated to the second position, the position of the first light-emitting component corresponds to the position of the light-splitting part.

[0011] In the aforementioned stage lighting fixture, at least two first light-emitting components are arranged circumferentially along the mounting mechanism. The light-changing component can rotate relative to the mounting mechanism. When the light-changing component rotates to the first position, the position of the first light-emitting component corresponds to the position of the first light-transmitting part. Thus, the light beam emitted from the first light-emitting component can be directly emitted through the corresponding first light-transmitting part. When the light-changing component rotates to the second position, the position of the first light-emitting component corresponds to the position of the beam-splitting part. At this time, the light beam emitted from the first light-emitting component is dispersed into two beams by the beam-splitting part. The two beams are emitted from the two first light-transmitting parts located on both sides of the beam-splitting part, so that the first light-transmitting part can emit light beams from two different first light-emitting components, thereby presenting different lighting effects. Compared with traditional technology, the aforementioned stage lighting fixture can adjust the effect of the light beam emitted by the first light-transmitting part by rotating the light-changing component, so that the first light-transmitting part can emit light beams from the same first light-emitting component or light beams from two different first light-emitting components, thereby presenting different lighting effects. There is no need to set different types of light sources on the stage lighting fixture, reducing the production cost of the stage lighting fixture.

[0012] In one embodiment, the mounting mechanism includes a mounting base and a first mounting member. The first light-emitting component is disposed on the first mounting member. The mounting base is disposed on the first mounting member and has at least two second light-transmitting portions. All the second light-transmitting portions are arranged in a one-to-one correspondence with the first light-emitting component. The light-changing component is rotatably disposed on the mounting base.

[0013] In one embodiment, the mounting base includes a support member and a second mounting member, the support member being disposed on the first mounting member, the second mounting member being disposed on the support member and having at least two second light-transmitting portions, and the light-changing element being rotatably disposed on the second mounting member.

[0014] In one embodiment, the mounting mechanism further includes a first transmission wheel, and the stage lighting fixture further includes a driving mechanism. The driving mechanism and the first transmission wheel are both disposed on the second mounting member. The driving mechanism is drivenly connected to the first transmission wheel, and the light-changing element is disposed on the axle of the first transmission wheel.

[0015] In one embodiment, the driving mechanism includes a second transmission wheel and a first driving member, the second transmission wheel being disposed on the output shaft of the first driving member, and the second transmission wheel engaging with the first transmission wheel in a transmission cooperation.

[0016] In one embodiment, the stage lighting fixture further includes a second light-emitting component, which is disposed on the first mounting member. The second mounting member has a third light-transmitting portion, the position of which corresponds to the position of the second light-emitting component. The first transmission wheel has a fourth light-transmitting portion, the position of which corresponds to the position of the third light-transmitting portion. The light-changing component has a fifth light-transmitting portion, the position of which corresponds to the position of the fourth light-transmitting portion.

[0017] In one embodiment, the stage lighting fixture further includes a focusing mechanism. The first mounting member has a first side and a second side facing each other. The first mounting member is provided with a mounting through hole penetrating the first side and the second side. The first light-emitting component is disposed on the first side, and the focusing mechanism is disposed on the second side. The support member passes through the mounting through hole. One end of the support member is connected to the focusing mechanism, and the other end of the support member is connected to the second mounting member. The focusing mechanism can drive the support member to reciprocate along the axial direction of the mounting through hole.

[0018] In one embodiment, the focusing mechanism includes a second driving member, a threaded component, and a connecting member. The second driving member is located on the second side, the threaded component is located on the output shaft of the second driving member, the connecting member has a threaded hole, the threaded component is threadedly engaged with the threaded hole, and the end of the support member away from the second mounting member is connected to the connecting member.

[0019] In one embodiment, the stage lighting fixture further includes a heat dissipation mechanism disposed on the second side.

[0020] In one embodiment, the heat dissipation mechanism includes heat dissipation fins and a fan, the heat dissipation fins being disposed on the second side, and the fan being disposed on the focusing mechanism and located on the side of the heat dissipation fins away from the second side.

Detailed Implementation

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] Please see Figures 1 to 5 One embodiment of this application provides a stage lighting fixture, including a mounting mechanism 100, a first light-emitting component 200, and a light-changing component 300. The first light-emitting component 200 is provided in at least two and is arranged along the circumference of the mounting mechanism 100. The light-changing component 300 is rotatably disposed on the mounting mechanism 100 and is provided with at least two first light-transmitting portions 310 and at least two light-splitting portions 320. The first light-transmitting portions 310 are arranged in a one-to-one correspondence with the first light-emitting components 200. All the first light-transmitting portions 310 are arranged along the circumference of the light-changing component 300, and a light-splitting portion 320 is provided between every two adjacent first light-transmitting portions 310.

[0038] When the light-changing element 300 rotates to the first position, the position of the first light-emitting element 200 corresponds to the position of the first light-transmitting part 310; when the light-changing element 300 rotates to the second position, the position of the first light-emitting element 200 corresponds to the position of the light-splitting part 320.

[0039] In the aforementioned stage lighting fixture, at least two first light-emitting components 200 are arranged circumferentially along the mounting mechanism 100. A light-changing element 300 can rotate relative to the mounting mechanism 100. When the light-changing element 300 rotates to a first position, the position of the first light-emitting component 200 corresponds to the position of the first light-transmitting part 310. Thus, the light beam emitted from the first light-emitting component 200 can directly pass through its corresponding first light-transmitting part 310. When the light-changing element 300 rotates to a second position, the position of the first light-emitting component 200 corresponds to the position of the beam-splitting part 320. At this time, the light beam emitted from the first light-emitting component 200 is dispersed into two beams by the beam-splitting part 320, and the two beams exit from the first light-transmitting part 310 respectively. The two first light-transmitting sections 310 on both sides of the beam splitter emit light beams, allowing the first light-transmitting section 310 to emit light beams from two different first light-emitting components 200, thereby presenting different lighting effects. Compared with traditional technology, the above-mentioned stage lighting fixture can adjust the effect of the light beam emitted by the first light-transmitting section 310 by rotating the light-changing component 300, so that the first light-transmitting section 310 can emit light beams emitted from the same first light-emitting component 200, or light beams emitted from two different first light-emitting components 200, thereby presenting different lighting effects. There is no need to set different types of light sources on the stage lighting fixture, reducing the production cost of the stage lighting fixture.

[0040] Furthermore, all the first light-emitting parts are arranged at intervals along the circumference of the mounting mechanism 100, and all the first light-transmitting parts 310 are arranged at intervals along the axial direction of the light-changing element 300. When the light-changing element 300 is rotated to the first position, the positions of all the first light-emitting parts 200 correspond one-to-one with the positions of all the first light-transmitting parts 310. When the light-changing element 300 is rotated to the second position, the positions of all the first light-emitting parts 200 correspond one-to-one with the positions of all the light-splitting parts 320.

[0041] To explain, different first light-emitting components 200 typically emit light beams of different colors. For example, among two adjacent first light-emitting components 200, one first light-emitting component 200 can emit a red light beam, and the other first light-emitting component 200 can emit a blue light beam. When the light-changing component 300 moves to the first position, the first light-transmitting portion 310 corresponding to each of the two first light-emitting components 200 can emit a red light beam and a blue light beam, respectively. When the light-changing component 300 moves to the second position, one of the first light-transmitting portions 310 moves to the position between the two first light-emitting components 200. At this time, a portion of the red light beam emitted by one of the first light-emitting components 200 is emitted from the first light-transmitting portion 310, and a portion of the blue light beam emitted by the other first light-emitting component 200 is also emitted from the first light-transmitting portion 310, so that the first light-transmitting portion 310 can emit two different colored light beams simultaneously, thereby presenting different lighting effects.

[0042] Furthermore, when the light-changing component 300 moves to the second position, the red light beam emitted by one of the first light-emitting components 200 and the blue light beam emitted by the other first light-emitting component 200 can be superimposed and mixed to produce a new color. The light beam of the new color can be emitted from the first light-transmitting part 310, thereby further presenting different lighting effects.

[0043] In one embodiment, the first light-transmitting part 310 includes an imaging lens, which is capable of receiving and emitting a light beam emitted from the first light-emitting component 200; in addition, the imaging lens can also focus and scatter the light beam, thereby achieving the best imaging effect.

[0044] Furthermore, the light-changing element 300 is disc-shaped, and multiple imaging lenses are provided. The multiple imaging lenses are arranged at intervals along the circumference of the disc-shaped light-changing element 300. The disc-shaped light-changing element 300 can rotate around its own axis, thereby switching between the first position and the second position.

[0045] Furthermore, in other embodiments, even richer lighting effects can be displayed by continuously rotating the light-changing element 300, which will not be elaborated here.

[0046] Please see Figure 1 In one embodiment, the stage lighting fixture also includes a base 400, on which the mounting mechanism 100 is rotatably disposed to facilitate adjustment of the direction of the beam emitted by the first light-transmitting part 310.

[0047] Furthermore, the rotational connection between the base 400 and the mounting mechanism 100 can be electrically controlled by an external drive structure, or the beam can be projected at any angle by a damped rotating shaft, which will not be elaborated here.

[0048] Please see Figures 4 to 5 In one embodiment, the mounting mechanism 100 includes a mounting base and a first mounting member 110. A first light-emitting component 200 is disposed on the first mounting member 110. The mounting base is disposed on the first mounting member 110 and is provided with at least two second light-transmitting portions 121. All the second light-transmitting portions 121 are provided in a one-to-one correspondence with the first light-emitting component 200. A light-changing component 300 is rotatably disposed on the mounting base.

[0049] The mounting base enables the rotation of the light-changing component 300 to be more stable and reliable. The light beam emitted by the first light-emitting component 200 on the first mounting component 110 can pass through the second light-transmitting part 121 and the first light-transmitting part 310 in sequence and finally be emitted to achieve different lighting effects.

[0050] Please see Figures 4 to 5In one embodiment, the mounting base includes a support member 130 and a second mounting member 120. The support member 130 is disposed on the first mounting member 110, and the second mounting member 120 is disposed on the support member 130 and has at least two second light-transmitting portions 121. The light-changing member 300 is rotatably disposed on the second mounting member 120.

[0051] The support member 130, which is mounted on the first mounting member 110, can support the second mounting member 120. The light-changing member 300 can rotate on the second mounting member 120 and switch between a first position and a second position. The light beam emitted by the first light-emitting member 200 passes through the second light-transmitting part 121 on the second mounting member 120 and the first light-transmitting part 310 on the light-changing member 300 in sequence and is finally emitted. This arrangement can improve the rotation reliability of the light-changing member 300, thereby improving the reliability of the stage lighting fixture during use.

[0052] Furthermore, the first mounting member 110 and the second mounting member 120 are spaced apart under the support of the support member 130. The second mounting member 120 can provide a platform for the dimmer member 300 to rotate, so as to ensure that the dimmer member 300 can rotate stably.

[0053] Please see Figures 3 to 6 In one embodiment, the mounting mechanism 100 further includes a housing 140, which has a communicating mounting port and a mounting cavity. The first mounting member 110 is disposed in the mounting cavity. The light-changing member 300 includes a light-changing ring 330 and a lampshade 340. The light-changing ring 330 is rotatably disposed on the second mounting member 120. The lampshade 340 is disposed on the side of the light-changing ring 330 away from the second mounting frame and has a first light-transmitting part 310. The lampshade 340 can seal the mounting port to prevent dust from entering the mounting cavity.

[0054] Furthermore, the housing 140 is rotatably disposed on the base 400 to facilitate adjustment of the direction of the light beam emitted by the first light-transmitting part 310.

[0055] Please see Figures 4 to 7 In one embodiment, the mounting mechanism 100 further includes a first transmission wheel 150, and the stage lighting fixture further includes a drive mechanism 500. The drive mechanism 500 and the first transmission wheel 150 are both disposed on the second mounting member 120. The drive mechanism 500 is drivenly connected to the first transmission wheel 150, and the light-changing element 300 is disposed on the axle of the first transmission wheel 150.

[0056] The drive mechanism 500 can drive the first transmission wheel 150 to rotate, thereby driving the light-changing element 300 on the first transmission wheel 150 to rotate, so that the light-changing element 300 can switch between the first position and the second position.

[0057] In one embodiment, the drive mechanism 500 includes a drive motor disposed on the second mounting member 120, and a first transmission wheel 150 disposed on the output shaft of the drive motor, so that the first transmission wheel 150 can rotate coaxially with the output shaft of the drive motor, thereby driving the light-changing member 300 to rotate.

[0058] Please see Figures 4 to 7 In one embodiment, the drive mechanism 500 includes a second drive wheel 520 and a first drive member 510. The second drive wheel 520 is disposed on the output shaft of the first drive member 510, and the second drive wheel 520 is in drive engagement with the first drive wheel 150.

[0059] The first driving component 510 outputs power to the second transmission wheel 520, enabling the second transmission wheel 520 to rotate. The second transmission wheel 520 is in transmission cooperation with the first transmission wheel 150, thereby driving the first transmission wheel 150 to rotate. The light-changing component 300 also rotates with the first transmission wheel 150, enabling the light-changing component 300 to switch between the first position and the second position.

[0060] In one embodiment, the outer periphery of the first transmission wheel 150 is provided with a first meshing tooth, and the outer periphery of the second transmission wheel 520 is provided with a second meshing tooth. The first meshing tooth can mesh with the second meshing tooth. In this way, when the first driving member 510 drives the second transmission wheel 520 to rotate, the first transmission wheel 150 can also rotate synchronously under the meshing action of the meshing teeth. The implementation cost is low and the transmission process is reliable.

[0061] Please see Figure 7 In one embodiment, the drive mechanism 500 further includes a drive belt 530, which is sleeved on the outside of the first drive wheel 150 and the outside of the second drive wheel 520.

[0062] Under the transmission action of the transmission belt 530, the first transmission wheel 150 and the second transmission wheel 520 can rotate synchronously. Thus, when the first driving member 510 drives the second transmission wheel 520 to rotate, the first transmission wheel 150 also rotates, thereby driving the light-changing member 300 to switch between the first position and the second position. This configuration has low implementation cost and reliable transmission process.

[0063] Furthermore, the outer periphery of the first drive wheel 150 is provided with a first meshing tooth, the outer periphery of the second drive wheel 520 is provided with a second meshing tooth, and the inner wall of the drive belt 530 is provided with a third meshing tooth. Both the first and second meshing teeth can mesh with the third meshing tooth to improve the frictional reliability between the first drive wheel 150, the second drive wheel 520 and the drive belt 530.

[0064] Please see Figure 7In one embodiment, the drive mechanism 500 further includes a first tensioning pulley 541 and a second tensioning pulley 542. Both the first tensioning pulley 541 and the second tensioning pulley 542 are disposed on the second mounting member 120. The outer periphery of the first tensioning pulley 541 and the outer periphery of the second tensioning pulley 542 abut against the transmission belt 530 to ensure that the transmission belt 530 is always kept taut, thereby ensuring the transmission effect of the transmission belt 530.

[0065] Furthermore, the drive mechanism 500 also includes a first mounting rod 551 and a second mounting rod, which are respectively disposed on two adjacent second light-transmitting portions 121. A first tensioning wheel 541 is rotatably disposed on the first mounting rod 551, and a second tensioning wheel 542 is rotatably disposed on the second mounting rod.

[0066] Please see Figures 5 to 7 In one embodiment, the stage lighting fixture further includes a second light-emitting component 600, which is disposed on a first mounting member 110. The second mounting member 120 is provided with a third light-transmitting part, the position of which corresponds to the position of the second light-emitting component 600. The first transmission wheel 150 is provided with a fourth light-transmitting part 151, the position of which corresponds to the position of the third light-transmitting part. The light-changing component 300 is provided with a fifth light-transmitting part 350, the position of which corresponds to the position of the fourth light-transmitting part 151.

[0067] The light beam emitted by the second light-emitting component 600 can be emitted through the third light-transmitting part, the fourth light-transmitting part 151 and the fifth light-transmitting part 350; this arrangement can further enrich the lighting effects of the stage lighting fixtures without affecting the position switching of the light-changing component 300.

[0068] In one embodiment, the first mounting component 110 includes a control motherboard 113 and a protective plate 114. The first light-emitting component 200 is an LED lamp bead, and the second light-emitting component 600 is a laser lamp. Both the LED lamp bead and the laser lamp are mounted on the control motherboard 113. The control motherboard 113 is used to supply power to the LED lamp bead and the laser lamp and control their light emission to give the stage lighting fixtures rich lighting effects. The protective plate 114 is spaced apart from the control motherboard 113 and located between the control motherboard 113 and the second mounting component 120 to protect the control motherboard 113.

[0069] In one embodiment, the second light-emitting component 600 includes a laser generator, a galvanometer, and a motor. The laser beam emitted by the laser generator is incident on the reflective surface of the galvanometer. The motor can drive the galvanometer to deflect, thereby changing the reflection angle of the laser beam and thus changing the trajectory of the laser beam, thereby presenting different spotlight illumination effects.

[0070] Optionally, the first light-transmitting part 310, the second light-transmitting part 121, the third light-transmitting part, the fourth light-transmitting part 151 and the fifth light-transmitting part 350 in the above embodiments can be lenses or light-transmitting holes, and can be flexibly adjusted according to specific application scenarios. No specific limitation is made here.

[0071] In one embodiment, the first light-transmitting part 310 and the fifth light-transmitting part 350 on the light-transmitting element 300 are lenses to block dust from entering the interior of the stage lighting fixture, and the second light-transmitting part 121, the third light-transmitting part and the fourth light-transmitting part 151 are light-transmitting holes to save costs.

[0072] Please see Figures 4 to 5 In one embodiment, the stage lighting fixture further includes a focusing mechanism 700. The first mounting member 110 has a first side 111 and a second side 112 opposite to each other. The first mounting member 110 is provided with a mounting through hole that passes through the first side 111 and the second side 112. The first light-emitting component 200 is disposed on the first side 111, the focusing mechanism 700 is disposed on the second side 112, and the support member 130 passes through the mounting through hole. One end of the support member 130 is connected to the focusing mechanism 700, and the other end of the support member 130 is connected to the second mounting member 120. The focusing mechanism 700 can drive the support member 130 to reciprocate along the axial direction of the mounting through hole.

[0073] The support member 130 passes through the mounting through hole of the first mounting member 110, and the opposite ends of the support member 130 are respectively connected to the focusing mechanism 700 and the second mounting member 120. Thus, when the focusing mechanism 700 drives the support member 130 to move back and forth along the axial direction of the mounting through hole, the second mounting member 120 can move closer to or away from the first mounting member 110, thereby allowing the first light-transmitting part 310 to move closer to or away from the first light-emitting component 200, changing the size and coverage of the light beam emitted from the first light-transmitting part 310, thereby achieving the focusing effect.

[0074] In one embodiment, the first light-transmitting part 310 includes at least one lens, and the focusing mechanism 700 can adjust the distance between the second mounting member 120 and the first mounting member 110 to adjust the distance between the first light-emitting component 200 and the lens, thereby changing the size and coverage of the light beam emitted from the lens to achieve the focusing effect.

[0075] Furthermore, placing the focusing mechanism 700 on the second side 112 optimizes the spatial layout within the housing 140. Specifically, placing the focusing mechanism 700 on the second side 112 of the first mounting member 110 instead of the first side 111 ensures that the first side 111 of the first mounting member 110 has sufficient space for the second mounting member 120 to approach the first mounting member 110, thus ensuring the focusing effect.

[0076] Please see Figures 4 to 5In one embodiment, the focusing mechanism 700 includes a second driving member 720, a threaded component 710, and a connecting member 730. The second driving member 720 is disposed on the second side 112, the threaded component 710 is disposed on the output shaft of the second driving member 720, the connecting member 730 has a threaded hole, the threaded component 710 is threadedly engaged with the threaded hole, and the end of the support member 130 away from the second mounting member 120 is connected to the connecting member 730.

[0077] The second driving member 720 can drive the threaded member 710 to rotate. The threaded member 710 is screwed into the threaded hole on the connector 730. When the threaded member 710 rotates, the connector 730 can drive the support member 130 to move back and forth along the axis of the mounting through hole, thereby allowing the first light-transmitting part 310 to move closer to or further away from the first light-emitting member 200, changing the size and coverage of the light beam emitted from the first light-transmitting part 310, thus achieving a focusing effect. With this configuration, the implementation cost is low and the focusing effect is reliable.

[0078] In one embodiment, the threaded component 710 is a screw, the external thread of which can be screwed into the internal thread of the screw hole to drive the support 130 to reciprocate along the axial direction of the mounting through hole.

[0079] Please see Figures 4 to 5 In one embodiment, the connector 730 includes a connecting plate, and the support 130 is provided with at least two members spaced apart circumferentially along the support plate to ensure the stability of the second mounting member 120 when the support 130 moves.

[0080] Furthermore, the focusing mechanism 700 also includes a connecting column and a mounting plate. One end of the connecting column is connected to the second side 112, and the mounting plate is connected to the end of the connecting column away from the second side 112. The second driving member 720 is disposed on the mounting plate, and the threaded member 710 passes through the mounting plate and is screwed into the threaded hole on the connecting member 730.

[0081] Furthermore, the connecting column is connected to the second side 112 by bolts.

[0082] In one embodiment, both the first drive component 510 and the second drive component 720 are drive motors to ensure drive reliability.

[0083] Please see Figures 2 to 3 In one embodiment, the stage lighting fixture also includes a heat dissipation mechanism 800, which is disposed on the second side 112.

[0084] The heat dissipation mechanism 800 can dissipate the heat generated by the operation of the first light-emitting component 200 and the second light-emitting component 600, preventing the stage lighting fixtures from overheating and affecting the lighting effect.

[0085] Alternatively, the heat dissipation mechanism 800 can dissipate heat through air cooling, liquid cooling, or by adding heat dissipation fins; no specific limitation is made here.

[0086] Please see Figures 2 to 3 In one embodiment, the heat dissipation mechanism 800 includes heat dissipation fins 810 and a fan 820. The heat dissipation fins 810 are disposed on the second side 112, and the fan 820 is disposed on the focusing mechanism 700 and located on the side of the heat dissipation fins 810 away from the second side 112.

[0087] The heat dissipation fins 810 located on the second side 112 of the first mounting member 110 can increase the heat dissipation area of ​​the first mounting member 110. The heat generated by the first light-emitting component 200 and the second light-emitting component 600 can be transferred to the heat dissipation fins 810 through the first mounting member 110 and dissipated through the heat dissipation fins 810. The fan 820 located on the focusing mechanism 700 can drive the airflow near the heat dissipation fins 810 to flow. The flowing airflow can better remove the heat on the heat dissipation fins 810 and further improve the heat dissipation effect.

[0088] Further, please refer to Figures 2 to 3 The heat dissipation fins 810 are provided in at least two, and all the heat dissipation fins 810 are spaced apart on the second side 112 along the first direction of the first mounting member 110.

[0089] This configuration can further increase the heat dissipation area of ​​the first mounting component 110 and improve heat dissipation efficiency.

[0090] For illustrative purposes, in the above embodiments, the first direction of the first mounting member 110 is the length or width direction of the first mounting member 110 (i.e., Figure 2 (as shown in direction A), which is the direction parallel to the plane where the first mounting member 110 is located.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
