Description

Technical Field

[0001] This invention belongs to the field of energy-saving lighting technology, specifically relating to a studio lighting deployment structure. Background Technology

[0002] With the rapid development of online live streaming, short video production, and converged media content production, studios, as the core venues for audio-visual content production, have placed higher demands on the professionalism, flexibility, and safety of their lighting systems. For these application scenarios, existing technologies typically employ pre-embedded suspension points, rigid trusses, or ceiling-mounted sliding rail systems to permanently fix lighting equipment such as LED film and television lights, soft panel lights, and contour spotlights below the ceiling, and arrange them according to professional lighting principles such as three-point lighting. This type of fixed lighting deployment structure can provide good lighting consistency and operational reliability in scenarios with a single program type, fixed host positions, and highly standardized recording processes. However, in practical applications, this type of fixed deployment has significant limitations: Before a live broadcast or recording begins, the studio typically requires numerous preparatory tasks, including site setup, equipment debugging, set construction, green screen installation, camera crane setup, and personnel rehearsal. This stage necessitates maintaining a clear ceiling to ensure uninterrupted operation of large backdrops, aerial machinery (such as cranes and track cameras), prop handling, and personnel movement. However, existing fixed lighting systems often cannot be quickly retracted or concealed, leaving the lights and their supporting structures suspended above the work area for extended periods. This not only occupies valuable vertical operating space but also increases the risk of collisions with hoisting equipment or personnel, posing safety hazards and severely hindering set construction efficiency.

[0003] If manual disassembly, temporary relocation, or covering is used, it will not only be time-consuming and labor-intensive, reducing preparation efficiency, but it will also easily cause problems such as misalignment of the original positioning of the lights, damage to power supply and signal cables, and loosening of DMX or power interfaces, thereby compromising the accuracy of the lighting scene reproduction and affecting the long-term stability and professionalism of the system. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a studio lighting deployment structure to solve the problems existing in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is a studio lighting deployment structure, including a mounting plate and a lighting module. The mounting plate is used to fix the lighting module to the top structure of the studio. A rotating joint, a limiting joint, and a lifting rod are provided between the mounting plate and the lighting module. The rotating joint is mounted on the mounting plate, and its output end is threadedly connected to the lifting rod. The lifting rod has a guide groove along its length, and one end of the lifting rod is fixedly connected to the lighting module. The limiting joint is mounted on the mounting plate and can be selectively inserted into or detached from the guide groove. When the limiting joint is inserted into the guide groove... When the circumferential rotation of the lifting rod is restricted, the rotation of the rotating joint is driven to rotate, which is converted into the axial linear motion of the lifting rod through the threaded joint, thereby realizing the height adjustment of the lighting module. When the limiting joint disengages from the guide groove, the lifting rod is released from the circumferential restriction and can rotate synchronously around its own axis with the rotating joint, thereby driving the lighting module to perform horizontal steering adjustment. By controlling the lifting rod to raise and rotate the lighting module to the preset retracted position, the working space at the top of the studio can be quickly released, realizing safe avoidance of scenery setting, hoisting, and personnel passage in a clear state.

[0006] Preferably, the mounting plate is provided with a mounting groove, and the limiting joint is housed within the mounting groove; the limiting joint is provided with a V-shaped guide groove, and a limiting post adapted to the V-shaped guide groove is fixedly installed in the mounting groove; an elastic reset member is provided between the limiting joint and the mounting groove, the elastic reset member being configured to apply a spring force toward the lifting rod to the limiting joint, so that in the natural state, the bottom of the V-shaped guide groove always remains in contact with the limiting post, and drives the limiting joint to be stably inserted into the guide groove; when an external force pushes the limiting joint, one inclined surface of the V-shaped guide groove slides along the limiting post, causing the limiting joint to shift laterally as a whole, thereby disengaging from the guide groove and releasing the circumferential limitation on the lifting rod.

[0007] Furthermore, a trigger is provided at one end of the lifting rod and the lighting module, and a height limiting component is provided at the other end of the lifting rod. When the lifting rod moves axially to a preset position, the trigger or the height limiting component contacts the limiting pair and applies a lateral thrust to the limiting pair, driving the limiting pair to overcome the elastic force of the elastic reset component and move laterally, thereby disengaging from the guide groove. After the limiting pair disengages from the guide groove, the lifting rod releases its circumferential limitation, and the subsequent rotational input of the rotating pair will be converted into rotational motion around its own axis, thereby driving the lighting module to perform horizontal turning.

[0008] Furthermore, the height limiting component and the lifting rod are connected by a threaded connection, which can be adjusted along the axial position of the lifting rod; by rotating the height limiting component, the axial positioning position of the height limiting component on the lifting rod is changed, thereby setting the upper limit position of the lighting module in the lifting stroke, realizing the mechanical limit and preset adjustment of the working height of the lighting module.

[0009] Furthermore, both the trigger and the height limiting component are provided with an annular groove centered on the axis of the lifting rod, and a control component is provided in the annular groove; the mounting plate is provided with a stop component that cooperates with the control component; when the lifting rod moves axially to a preset position, the stop component is located in the corresponding annular groove and contacts and cooperates with the control component, thereby triggering the stop component and causing the rotating pair to stop receiving power input.

[0010] Furthermore, the control component can be positionally adjusted along the circumference of the annular groove and can be locked and fixed relative to the trigger or height limiting component; by adjusting the circumferential position of the control component in the annular groove, the contact timing between the stop component and the control component is set, thereby limiting the travel range of the lifting rod driving the lighting module to rotate, and realizing the preset and control of the horizontal turning angle of the lighting module.

[0011] Furthermore, the stop component is a power-off button, which is mounted on the mounting plate and electrically connected to the power source driving the rotating pair; the control component has a slope; when the lifting rod moves to the preset position, the stop component moves synchronously with the lifting rod and enters the annular groove, and then the lifting rod drives the control component to rotate circumferentially, so that the slope abuts against and presses the power-off button, thereby cutting off the power supply of the power source and stopping the rotating pair from operating.

[0012] Preferably, the rotating joint includes a drive module and a manual module, with a clutch switching mechanism between the drive module and the manual module; the drive module includes a motor and a reduction transmission mechanism driven by the motor, the reduction transmission mechanism being a worm gear mechanism or a gear transmission mechanism; when the clutch switching mechanism switches to manual mode, the transmission connection between the drive module and the lifting rod is disconnected, allowing the manual module to directly drive the lifting rod to perform lifting or rotation operations.

[0013] Preferably, the system also includes a central controller, and the plurality of the rotating joints are connected to the central controller via a communication bus; the central controller is configured to send synchronous control commands to each rotating joint, thereby releasing the overall work space at the top of the studio.

[0014] The main technical effects of this invention are reflected in the following aspects: This invention constructs a mechanically linked, dual-degree-of-freedom switching mechanism by setting a rotating joint, a limiting joint, and a lifting rod with a guide groove between the mounting plate and the lighting module. When the limiting joint is inserted into the guide groove, the lifting rod is circumferentially constrained, and the rotation of the rotating joint becomes axial linear motion, achieving height adjustment; when the limiting joint disengages, the lifting rod can rotate accordingly, achieving horizontal turning. This allows the same drive system to perform precise lighting positioning and also to raise and move the lamp away from the work area when needed, solving the problem of fixed lamps occupying overhead space.

[0015] The limiting pair uses a V-shaped guide groove in conjunction with a fixed limiting post, and is pre-tightened by an elastic reset component. It stably embeds into the guide groove in its natural state, ensuring no shaking during lifting. When the lifting rod reaches the preset position, the trigger or height limiting component automatically pushes the limiting pair laterally, using the guiding effect of the V-shaped inclined surface to achieve smooth disengagement. Automatic switching between "lifting → rotating" modes can be completed without sensors or electronic control commands, making it particularly suitable for broadcast environments with high-frequency transitions.

[0016] The height limiter is threaded onto the lifting rod, allowing for precise setting and locking of the working height during the commissioning phase. The control component is installed in an annular groove for preset retraction / reset rotation angles. Both are purely mechanical positioning elements, independent of electronic storage or external calibration. Each time the system retracts and then resets, it reverses its original path until it reaches the same height limit position and control angle. This ensures that the lighting module can reproduce the original lighting position with millimeter-level accuracy even after multiple avoidance maneuvers, meeting the stringent requirements of professional recording for consistent lighting.

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, 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 the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0019] The studio lighting deployment structure provided by this invention is mainly used in scenarios that require frequent scene changes, such as converged media studios, virtual studios, short video production rooms, and broadcast television recording venues. However, its application is not limited to these. It can also be applied to other places with similar overhead space management needs, such as stage theaters, exhibition spaces, film and television studios, or industrial inspection lighting systems.

[0020] Furthermore, the worm gear drive, threaded lifting mechanism, micro switch, RS485 communication bus, elastic return spring, and the V-shaped guide groove 15 and limit post 12 mating structure mentioned above are all conventional mechanical and electrical components well-known to those skilled in the art. Their specific principles, selection, and installation methods are common knowledge in this industry, so detailed structures and working mechanisms will not be elaborated here.

[0021] Example 1 This embodiment discloses a studio lighting deployment structure. Its core lies in the collaborative design of mechanical and control systems, which enables the lighting module 2 to switch quickly, safely, and repeatedly between "working state" and "retreat state" without changing the original lighting scheme. This effectively solves the problem that traditional fixed lighting systems hinder set design, hoisting, and equipment installation due to long-term occupation of ceiling space.

[0022] It is particularly important to emphasize that the "retract" function of this structure is only for temporary relocation, such as when changing backdrops, installing green screens, setting up camera cranes, or hoisting large props, temporarily moving the lights away from the work area. After the scene setup is complete, the lights will precisely return to their original working height and angle, ensuring that professional lighting parameters such as three-point lighting, key light / fill light / rim light are completely consistent, and that there is no deviation in the lighting effect of the recorded footage before and after. This differs from the "scene memory" of dimmable intelligent lights; this invention guarantees high-precision reproduction of physical positions.

[0023] Specifically, see Figure 1The lighting deployment structure mainly includes a mounting plate 1 and a lighting module 2. The mounting plate 1 is used to fix the system to the ceiling structure of the studio. The mounting plate 1 is firmly fixed to the load-bearing structure of the studio ceiling by bolts or embedded parts, serving as the support base for the entire system. The lighting module 2 can be a commonly used studio lighting fixture such as an LED film and television light, a soft flat panel light, or a contour spotlight. It is rigidly connected to the lower end of the lifting rod 4 through a connecting bracket.

[0024] Preferred, see Figure 1 , Figure 3 A rotary joint 3, a limiting joint 14, and a lifting rod 4 are provided between the mounting plate 1 and the lighting module 2. The lifting rod 4 is a long strip of metal (such as a threaded rod) with a straight guide groove 41 along its axial direction. The rotary joint 3 is mounted on the mounting plate 1, and the output end of the rotary joint 3 (such as a worm gear or lead screw) and the lifting rod 4 are connected by a threaded connection. When the rotary joint 3 rotates, if the lifting rod 4 is constrained circumferentially, the threaded joint will rotate into axial linear motion, driving the lighting module 2 to rise and fall; if it is free circumferentially, the whole unit will rotate accordingly, achieving horizontal turning.

[0025] It is worth noting that, see Figure 2 The mounting plate 1 has a mounting groove 11, and the limiting pair 14 is housed within the mounting groove 11. The limiting pair 14 has a V-shaped guide groove 15, and a limiting post 12 adapted to the V-shaped guide groove 15 is fixedly disposed within the mounting groove 11. The limiting post 12 and the limiting pair 14 form a sliding fit. An elastic reset member 13 (such as a spring) is provided between the limiting pair 14 and the mounting groove 11. The elastic reset member 13 is configured to apply a spring force toward the lifting rod 4 to the limiting pair 14, so that in its natural state, the bottom of the V-shaped guide groove 15 always remains in contact with the limiting post 12, driving the limiting pair 14 to stably insert into the guide groove 41. During daily use in the studio, the spring force keeps the bottom of the V-shaped guide groove 15 tightly against the limiting post 12, and drives the front end of the limiting pair 14 to insert into the guide groove 41 of the lifting rod 4, thereby restricting the circumferential rotation of the lifting rod 4. At this time, the system is in "lifting mode". However, when recording ends or when a scene needs to be switched, the director or lighting technician can activate the "retracted mode" through the control panel. The limiting can be released in two ways: one is to manually push the side wall of the limiting pair 14, so that one side of the inclined surface of the V-shaped guide groove 15 slides along the limiting post 12, generating lateral displacement, thereby disengaging from the guide groove 41; the other is to use an automatic triggering mechanism—a trigger element 42 is set at one end of the lifting rod 4 near the lighting module 2, and a height limiting element 43 is set at the other end. When the lifting rod 4 rises to the preset height (such as the retracted position), the trigger element 42 or the height limiting element 43 will contact the side of the limiting pair 14 and apply a lateral thrust, overcoming the spring force and automatically disengaging from the guide groove 41. This design realizes automatic mode switching without manual intervention, significantly improving operational efficiency.

[0026] Furthermore, regarding trigger 42 and height limiter 43: see [link / reference] Figure 3 The height limiting component 43 and the lifting rod 4 are connected by a threaded connection, which can be adjusted along the axial position of the lifting rod 4. By rotating the height limiting component 43, the axial positioning position of the height limiting component 43 on the lifting rod 4 is changed, thereby setting the upper limit position of the lighting module 2 in the lifting stroke, realizing the mechanical limit and preset adjustment of the working height of the lighting module 2. The mechanical limit is stable and reliable, unaffected by the power supply or control system, and is suitable for height preset in different program scenarios.

[0027] When the lifting rod 4 moves axially to a preset position, the trigger 42 or the height limiting member 43 contacts the limiting pair 14 and applies a lateral thrust to the limiting pair 14, driving the limiting pair 14 to overcome the elastic force of the elastic reset member 13 and move laterally, thereby disengaging from the guide groove 41; after the limiting pair 14 disengages from the guide groove 41, the lifting rod 4 releases its circumferential limitation, and the subsequent rotational input of the rotating pair 3 will be converted into rotational motion around its own axis, thereby driving the lighting module 2 to perform horizontal turning.

[0028] Further, see Figure 4 To prevent the lighting module 2 from colliding with surrounding structures (such as a hanging backdrop, camera jib, or adjacent lighting fixtures) due to excessive rotation during retraction, both the trigger 42 and the height limiting member 43 are provided with annular grooves 44 centered on the axis of the lifting rod 4. A control member 45 is provided within the annular groove 44. The mounting plate 1 is provided with a stop member 46 (such as a micro switch or power-off button) that cooperates with the control member 45. When the lifting rod 4 moves axially to a preset position, the stop member 46 is located within the corresponding annular groove 44 and contacts the control member 45, thereby triggering the stop member 46 and causing the rotating joint 3 to stop receiving power input, achieving precise angle stopping.

[0029] The control element 45 can be adjusted in position along the circumference of the annular groove 44 and can be locked and fixed relative to the trigger element 42 or the height limiting element 43; thus, the maximum turning angle (such as ±45°, 90°, etc.) can be flexibly set to meet different retracting posture requirements. By adjusting the circumferential position of the control element 45 in the annular groove 44, the contact timing between the stop element 46 and the control element 45 can be set, thereby limiting the travel range of the lifting rod 4 driving the lighting module 2 to rotate, and realizing the preset and control of the horizontal turning angle of the lighting module 2. To facilitate operators to accurately set the angle, the inner wall of the annular groove 44 can be integrated with angle scale markings (such as 0°~360° or relative deviation angle scale) to achieve visual adjustment.

[0030] The key is that the height limiter 43 and the control unit 45 together form a "mechanical memory" unit, ensuring that the luminaire strictly returns to its original working state each time it is retracted and reset. During the initial commissioning phase, the height limiter 43 is precisely set and locked by the lighting engineer according to the standard lighting scheme (e.g., a front light height of 2.8 meters). This position serves as the working height reference, and regardless of the number of retraction-reset cycles, the lifting endpoint remains unchanged as long as it is not manually adjusted. The circumferential angle of the control unit 45 within the annular groove 44 is also set during commissioning (e.g., retracting with a 60° leftward deviation to avoid the central passage) and fixed by the locking mechanism. During reset, the system rotates in the opposite direction to the same control unit 45 position and stops, ensuring complete horizontal restoration. Because both the height limiter 43 and the control unit 45 are purely mechanical positioning elements, they do not rely on sensors, encoders, or software storage. Even in the event of power failure, system restart, or communication interruption, as long as the physical position is not disturbed, the luminaire can reliably return to its original working state. This "mechanical memory" characteristic is significantly superior to motorized gimbal solutions that rely on electronic memory, and is especially suitable for professional scenarios with extremely high requirements for lighting reproduction accuracy, such as live news broadcasting and virtual film production.

[0031] It is worth noting that the stop element 46 is preferably a power-off button, which can be a normally closed micro switch that disconnects the motor power circuit when pressed. The power-off button is located on the mounting plate 1 and electrically connected to the power source driving the rotating pair 3; the control element 45 has a slope; when the lifting rod 4 moves to the preset position, the stop element 46 moves synchronously with the lifting rod 4 and enters the annular groove 44. Subsequently, the lifting rod 4 drives the control element 45 to rotate circumferentially, causing the slope to abut against and press the power-off button, thereby cutting off the power supply to the power source and stopping the rotating pair 3 from operating.

[0032] Preferably, the rotary joint 3 includes a drive module and a manual module, with a clutch switching mechanism between them. The drive module includes a motor and a reduction gear mechanism driven by the motor, which is a worm gear mechanism or a gear transmission mechanism. When the clutch switching mechanism is switched to manual mode, the transmission connection between the drive module and the lifting rod 4 is disconnected, allowing the manual module to directly drive the lifting rod 4 for lifting or rotating operations. The manual module is a handwheel connected to the input end via a splined shaft. When switched to manual mode, the clutch mechanism disengages the motor output shaft from the transmission chain, preventing reverse drag, allowing the operator to directly rotate the handwheel for fine lifting or steering adjustments, suitable for power outage emergencies, debugging, calibration, and other scenarios.

[0033] Preferably, multiple such lighting deployment structures can be connected to a central controller (such as a PLC or a dedicated lighting console) via RS485 or CAN communication bus. The central controller can send a synchronization command with one click, causing all lighting modules 2 to rise to the height limit position according to a unified logic, and then rotate synchronously to the retracted angle, thus freeing up the top space as a whole and greatly improving the efficiency and safety of set design in large studios.

[0034] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
