Description

Technical Field

[0001] This invention relates to the field of installation technology for immersive projection equipment, and in particular to an integrated projection lighting device and its control method. Background Technology

[0002] The installation technology of immersive projection equipment currently faces two main demand scenarios: temporary modifications and permanent modifications. Temporary modifications (such as short-term exhibitions and event venues) require extremely high levels of rapid deployment, flexible adjustment, and spatial adaptability of the equipment, but existing technologies suffer from significant bottlenecks.

[0003] Low equipment integration: Traditional solutions rely on temporary structures (such as trusses and independent hangers) to install projectors, speakers and other equipment separately, which makes it difficult for multiple devices to coordinate and results in redundant space occupation.

[0004] Limited adjustability: Existing brackets (such as adjustable brackets) only support manual angle fine-tuning of a single device, which is difficult to meet the needs of immersive scenarios for dynamic synchronization of multiple projected images;

[0005] Low installation efficiency: Each piece of equipment needs to be fixed, wired and debugged individually, and the additional support structure is prone to interference with the existing facilities in the space (such as ceiling and lighting fixtures), which prolongs the deployment cycle.

[0006] Therefore, there is an urgent need to design a technical solution that can achieve integrated, dynamically adjustable, and efficient installation of multiple projection devices. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated projection lighting device and its control method to solve the problems existing in the prior art. It can realize the integrated installation of multiple projection devices, has high installation efficiency, and can be dynamically adjusted.

[0008] To achieve the above objectives, the present invention provides the following solution:

[0009] This invention provides an integrated projection lighting device, comprising:

[0010] The combined hanger includes a first hanger and a second hanger arranged in parallel, and the distance between the first hanger and the second hanger is adjustable;

[0011] A connecting rod, one end of which is used to connect to the ceiling at the installation location, and the other end is connected to the first hanger;

[0012] Multiple adjustment mechanisms are respectively disposed on the first hanger and the second hanger. Each adjustment mechanism is connected to a projector and can drive the projector to rotate a set angle in the horizontal and / or vertical directions.

[0013] The chandelier housing is arranged on the outside of the combined hanging frame, and the chandelier housing has multiple projection ports, and the projection lens of the projector can project outward through the projection ports at the corresponding positions.

[0014] Preferably, the first hanger and the second hanger are connected by a telescopic mechanism, which can adjust the distance between the first hanger and the second hanger.

[0015] Preferably, it also includes multiple locking mechanisms, such as manual screws and electromagnetic latches; the locking mechanisms are used to fix the telescopic mechanism and the adjusting mechanism in a set position respectively.

[0016] Preferably, the adjustment mechanism includes a horizontal adjustment device and a rotary adjustment device; the horizontal adjustment device includes a first mounting bracket rotatably mounted on the combined hanger, the first mounting bracket having a driven gear meshing with a driving gear, the driving gear being driven and connected to a first drive motor, the first drive motor being fixed to the combined hanger; a second mounting bracket rotatably mounted at the bottom of the first mounting bracket, the second mounting bracket being driven and connected to a second drive motor via a worm gear mechanism, the second drive motor being mounted on the first mounting bracket; the projector is fixedly mounted at the bottom of the second mounting bracket.

[0017] Preferably, the chandelier housing includes a first housing and a second housing, the top of the first housing is fixed to the ceiling at the installation location, and the second housing is detachably connected to the bottom of the first housing; the chandelier housing has multiple receiving cavities, which are respectively used to accommodate the combined hanging bracket and the projector.

[0018] Preferably, the outer surface of the chandelier housing is made of matte metal, and the interior of the chandelier housing has heat dissipation holes.

[0019] Preferably, the chandelier housing is provided with a power distribution module, which is connected to an external power source via wires, and the power distribution module can distribute the power into two paths: one path to power the projector and the other path to power the telescopic mechanism and the adjustment mechanism.

[0020] Preferably, the system further includes a controller, which is mounted on the combined hanger. The controller is connected to the telescopic mechanism, the adjusting mechanism, and the electromagnetic latch signal, respectively. The controller is wirelessly connected to a remote control, which can remotely operate the controller to control the telescopic mechanism, the adjusting mechanism, and the electromagnetic latch action, respectively.

[0021] Preferably, the combined hanger is equipped with multiple infrared sensors, which are signal-connected to the controller and connected to an alarm. The infrared sensors are used to monitor the distance between the combined hanger and surrounding facilities, and can stop the telescopic mechanism and adjustment mechanism and issue an alarm when the distance between the combined hanger and surrounding facilities shrinks to a set value.

[0022] The present invention also provides a control method for the projection lighting integrated device as described above, comprising the following steps:

[0023] Connect the combined hanging bracket and chandelier housing to the ceiling at the installation location;

[0024] By synchronously adjusting the horizontal deflection angle and vertical rotation angle of multiple projectors through the controller, the horizontal coverage of the projectors is adjusted and the vertical tilt angle is calibrated to ensure seamless splicing of multiple images;

[0026] The present invention achieves the following technical effects compared to the prior art:

[0027] This invention mounts multiple projectors on a combined hanging bracket, which is then fitted with a chandelier housing. By integrating multiple projectors and lighting fixtures into a unified hanging bracket structure, it replaces the original chandelier, eliminating the need for repeated support structure construction. Each projector is connected to the combined hanging bracket via its own adjustment mechanism, and a collaborative adjustment mechanism supports synchronized angle adjustments for multiple projectors, achieving dynamic projection adaptation. The chandelier housing is designed to be compatible with existing lighting fixtures, directly replacing them and eliminating disruptive modifications to the space. This enhances the concealment and aesthetics of the projectors and the combined hanging bracket. Thus, this invention, through the pre-integration of the combined hanging bracket and chandelier housing's lighting functions, overcomes the limitations of existing "single-point optimization" technologies, achieving integrated installation and dynamic adjustment of multiple devices with high installation and adjustment efficiency.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The purpose of this invention is to provide an integrated projection lighting device and its control method to solve the problems existing in the prior art. It can realize the integrated installation of multiple projection devices, has high installation efficiency, and can be dynamically adjusted.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] In existing technologies, temporarily modified immersive audio-visual spaces rely on temporary structures (such as trusses) to separately install projectors, speakers, and other equipment, leading to the following key drawbacks:

[0037] Multiple device integration is difficult: Existing projector mounts are mostly designed for single projectors, lacking solutions for centralized installation of multiple devices. Individual support structures are required, resulting in large space requirements and cumbersome installation steps. Insufficient adjustment flexibility: Relying on manual or simple mechanical structures to adjust angles cannot meet the complex dynamic projection requirements of immersive scenarios. Low installation efficiency: Each device needs to be fixed and debugged individually, and additional support structures can easily interfere with existing space facilities (such as ceilings and lighting fixtures), further extending the deployment cycle. To solve this problem, the first objective of this invention is to provide a projection lighting integrated device, referencing... Figure 1 , Figure 2 and Figure 3This invention comprises: a combined hanging bracket, a connecting vertical rod, an adjusting mechanism, and a chandelier housing 6. The combined hanging bracket is made of aluminum alloy; alternatively, it can be made of carbon fiber (30% weight reduction) or copper alloy (enhanced heat dissipation). It includes a first hanging bracket 1 and a second hanging bracket 2 arranged in parallel, and the distance between the first hanging bracket 1 and the second hanging bracket 2 is adjustable, thereby allowing the overall height of the combined hanging bracket to be adjusted according to actual needs. The upper end of the stainless steel connecting vertical rod is fixed to the ceiling with expansion bolts, and the lower end is connected to the combined hanging bracket. The connecting vertical rod can be formed by two nested support rods, one of which is threaded or snapped to the outside of the other support rod. By adjusting the axial distance between the two support rods, the height of the connecting vertical rod can be adjusted between 0.5 and 1.5 meters. By adjusting the length of the connecting vertical rod, the overall height of the combined hanging bracket can be adjusted. The position of the combined hanging bracket and the ceiling can be quickly adjusted according to the space dimensions to reduce interference with existing facilities. In addition, in one embodiment, the lower end of the connecting vertical rod is connected to the combined hanging bracket via a universal joint, allowing the combined hanging bracket to be adjusted horizontally by ±5°. Multiple adjustment mechanisms are respectively set on the first hanging bracket 1 and the second hanging bracket 2. Each adjustment mechanism is connected to a projector 3 and can drive the projector 3 to rotate at a set angle in the horizontal and / or vertical directions. The chandelier housing 6 is arranged on the outside of the combined hanging bracket, and the chandelier housing 6 has multiple projection ports. The projection lens of the projector 3 can project outward through the corresponding projection ports. The chandelier housing 6 not only protects and shields the combined hanging bracket and the projector 3, but also has a lamp bead structure inside, so it can replace traditional lamps to achieve the lighting function. This invention enables rapid integrated installation. Multiple projectors 3 are centrally fixed through a modularly designed combination bracket, eliminating the need for separate support structures and significantly shortening installation time. It allows for flexible multi-angle adjustment of the projectors 3, with the adjustment mechanism supporting dynamic adjustment of the projection angle to adapt to complex spatial requirements. It possesses spatial adaptability and concealment, with the overall structure directly replacing the original chandelier, reducing destructive modifications to the original space. At the same time, it integrates the lighting function of the chandelier housing 6 with the projection function of the projectors 3, enhancing both aesthetics and practicality.

[0038] In one embodiment, the first hanger 1 and the second hanger 2 are connected by a telescopic mechanism 7. The telescopic mechanism 7 can adjust the distance between the first hanger 1 and the second hanger 2. The specific structure of the telescopic mechanism 7 is not limited. In one embodiment, the telescopic mechanism 7 includes a telescopic sleeve and a telescopic cylinder. The two ends of the vertically arranged telescopic sleeve are respectively connected to the first hanger 1 and the second hanger 2. The telescopic cylinder is arranged parallel to the telescopic sleeve, or the telescopic cylinder is disposed inside the telescopic sleeve. One end of the telescopic cylinder is fixedly connected to the first hanger 1, and the other end is connected to the telescopic push rod of the telescopic cylinder to the second hanger 2. By axially moving the telescopic push rod, the telescopic sleeve can be extended or shortened, thereby adjusting the distance between the first hanger 1 and the second hanger 2. In one embodiment, for ease of remote control... To control the telescopic process, this embodiment replaces the telescopic cylinder with an electric push rod. The electric push rod is wirelessly connected to a remote controller, enabling remote control of its extension or retraction. The electric push rod has a stroke of 1-3 meters, a thrust of 500N, and a telescopic speed of 10cm / s. To avoid the inability to adjust after a power outage, this embodiment also includes a manual backup mode. A mechanical manual adjustment mechanism is also provided on the telescopic mechanism 7. For example, a screw-nut pair can be used to adjust the telescopic mechanism 7. The screw is mounted on the first hanger 1, and the nut is fitted onto the screw. The nut is connected to the second hanger 2 via a connecting block. One end of the screw of the screw-nut pair is equipped with a hand crank, which can be used to mechanically adjust the distance between the first hanger 1 and the second hanger 2 to cope with power outages.

[0039] Once the combined mounting bracket is adjusted to the set height and the projector 3 is adjusted to the set angle, a locking mechanism is designed in one embodiment to ensure stability during use. The locking mechanism consists of a manual screw and an electromagnetic latch, which work together. After adjustment, the manual screw can be screwed into the threaded holes at the corresponding positions of the telescopic mechanism 7 and the adjustment mechanism to manually lock the telescopic mechanism 7 and the adjustment mechanism. In addition, to improve convenience, an electromagnetic latch is designed. The specific structure of the electromagnetic latch is a mature technology and is not limited. It is similar to an electronic lock structure and can lock the telescopic mechanism 7 and the adjustment mechanism to fix the combined mounting bracket and the projector. The electromagnetic latch is remotely controlled to open and close, realizing the remote locking or one-click unlocking function of the telescopic mechanism 7 and the adjustment mechanism.

[0040] In one embodiment, the adjustment mechanism includes a horizontal adjustment device 4 and a rotary adjustment device 5, which work together to achieve angle adjustment of the projector 3 in both the horizontal and vertical directions. The specific structures of the horizontal adjustment device 4 and the rotary adjustment device 5 are not limited. In this embodiment, the horizontal adjustment device 4 adopts a gear set structure, including a first mounting bracket rotatably mounted on the combined hanger. The first mounting bracket can rotate around the hanger rod of the combined hanger. A driven gear is provided on the first mounting bracket, and the driven gear meshes with a driving gear. The driving gear is connected to a first drive motor, which is fixed to the hanger rod of the combined hanger. The driving gear and the driven gear form a gear set. The output shaft of the first drive motor drives the driving gear to rotate, and the driving gear drives the driven gear meshing with it to rotate. Since the gear shaft of the driven gear is fixedly mounted to the first mounting bracket, the driven gear will drive the first mounting bracket to rotate around the corresponding hanger rod by a set angle. In this embodiment, the gear set has a gear module of 1.5, 30 teeth, a transmission ratio of 1:5, and an adjustment accuracy of ±0.3°. A gear set is used to achieve a horizontal angle adjustment of ±30° for the projector 3. A second mounting bracket is rotatably mounted on the bottom of the first mounting bracket. The second mounting bracket is connected to a second drive motor via a worm gear mechanism, and the second drive motor is mounted on the first mounting bracket. The projector 3 is fixedly mounted on the bottom of the second mounting bracket. The output shaft of the second drive motor is connected to a worm gear drive, which in turn connects to a worm. The worm gear mechanism enables the steering of the power. The worm is vertically arranged, and its end is fixedly connected to the second mounting bracket. Therefore, the rotation of the worm will cause the second mounting bracket to rotate around a vertical axis, thereby driving the projector 3 on the second mounting bracket to rotate. The projector 3 rotates, supported by a worm gear mechanism that allows for 360° vertical rotation. Both the first and second drive motors are micro-motors. The coordinated control of the gear set and worm gear mechanism is achieved through two micro-motors (stepper motors, 0.1° accuracy), supporting synchronous adjustment of multiple devices. This mechanism enables vertical and horizontal rotation adjustment of the projector 3. In this embodiment, the worm gear has two threads, the worm wheel has 40 teeth, and the transmission ratio is 1:20. The worm gear has a self-locking function to prevent backlash. The maximum torque output of the worm gear is 5 N·m, suitable for projectors 3 weighing less than 10 kg. Besides this, other structures can also be used to adjust the angle of the projector 3, such as a sprocket and chain structure with a drive motor, or a linkage mechanism, etc. Specific details are not elaborated here.

[0041] In one embodiment, the chandelier housing 6 includes a first housing and a second housing. The top of the first housing is fixed to the ceiling at the installation location, and the second housing is detachably connected to the bottom of the first housing. The chandelier housing 6 has multiple accommodating cavities, which respectively accommodate the combined hanging bracket and the projector 3. The chandelier housing 6 has the same appearance as the original chandelier, with only the projection lens and light source exposed. The outer surface of the chandelier housing 6 is made of matte metal, and the interior of the chandelier housing 6 has heat dissipation holes. In addition, an ambient light sensor can be integrated into the chandelier housing 6 to automatically adjust the projection brightness according to the ambient brightness. The combined hanging bracket and the projector 3 are enclosed by the chandelier housing 6, exposing only the essential functional components (lens and light source); reducing destructive modifications, eliminating the need to remove the ceiling or perform additional construction, and preserving the integrity of the original space.

[0042] In one embodiment, a power distribution module is provided inside the chandelier housing 6. The power distribution module is connected to an external power source via wires. The ceiling power supply line is connected to the power distribution module inside the chandelier housing 6, and outputs power in two ways. One way powers the projector 3 (DC 24V), with a voltage and current of 24V / 5A and an overcurrent protection threshold of 6A. The other way powers the drive motor of the adjustment mechanism and the electric push rod of the telescopic mechanism 7 (DC 12V), with a voltage and current of 12V / 3A for the drive motor, supporting an instantaneous peak current of 5A. This invention features a centralized power distribution module and a quick-release interface. Power supply is simplified: a single line is connected, with two outputs (the projector 3 and the motor are powered independently); maintenance is convenient: the chandelier housing 6 can be quickly disassembled for easy equipment replacement or maintenance. The controller is mounted on the combined hanging bracket and is connected to the telescopic mechanism 7, the adjustment mechanism, and the electromagnetic latch signal. The controller is wirelessly connected to a remote control, which can remotely control the controller to control the telescopic mechanism 7, the adjustment mechanism, and the electromagnetic latch. The remote control sends commands to the controller (MCU) via Bluetooth / WiFi. The controller (MCU) has a built-in STM32F407 chip and supports multiple PWM signal outputs. The communication protocol uses Bluetooth 5.0 (transmission distance 50 meters) and is compatible with WiFi module (ESP32) as a backup. After the MCU parses the commands, it drives the drive motors (accuracy 0.1°) of the horizontal adjustment device 4 and the rotation adjustment device 5, as well as the electric push rod of the telescopic mechanism 7, to realize the automatic adjustment process.

[0043] In one embodiment, the combined hanger is equipped with multiple infrared sensors, which are connected to the controller and an alarm. The infrared sensors monitor the distance between the combined hanger and surrounding facilities, and when the distance between the combined hanger and surrounding facilities decreases to a set value, the controller stops the telescopic mechanism 7 and the adjustment mechanism, and issues an alarm. The dynamic adjustment process in this embodiment is as follows:

[0044] User input command: Select "screen blending mode" via remote control; Signal processing: MCU receives the command, calls preset angle parameters, and synchronously drives the drive motors of multiple projectors 3; Angle synchronization: Horizontal adjustment device 4 adjusts the horizontal coverage of projectors 3, and rotation adjustment device 5 calibrates the vertical tilt angle to ensure seamless splicing of multiple screens; Locking position: The controller controls the electromagnetic latch to automatically lock the adjustment device to prevent displacement. Telescopic adaptation process: Measuring space dimensions: The user inputs the target length of the combined bracket (e.g., 2.5 meters) via remote control; Electric push rod action: Telescopic mechanism 7 extends to the set length and is fixed by locking screws or electromagnetic latches. Conflict detection: Infrared sensors monitor the distance between the combined bracket and surrounding facilities in real time. If interference is detected, telescopic extension automatically stops and an alarm is triggered. The alarm device can be a buzzer or light alarm electrically connected to the controller. This invention uses a combined bracket to centrally support multiple projectors 3, eliminating the need for independent support structures (such as traditional trusses). Dual-degree-of-freedom dynamic adjustment: Horizontal / rotation adjustment devices 5 work together, supporting remote synchronous control. Intelligent conflict detection: Infrared sensors monitor the distance between the combined bracket and surrounding facilities in real time to avoid installation interference. In terms of installation efficiency: traditional solutions require 4-6 hours, while this invention shortens it to 1-2 hours (actual measurement data); in terms of adjustment accuracy: the angle synchronization error of this invention is ≤0.5°, and the screen splicing gap is <1mm; in terms of space compatibility: the telescopic mechanism 7 of this invention supports length adjustment of 1-3 meters, adapting to more than 90% of standard spaces.

[0045] The present invention also provides a method for controlling the above-mentioned integrated projection lighting device, comprising the following steps:

[0046] Connect the combined hanging bracket and chandelier housing 6 to the ceiling at the installation location. The installation process is as follows: Remove the existing chandelier: Disconnect the power, remove the old light fixture, and retain the ceiling power supply line. Assemble the integrated equipment: Fix the projector 3 to the rotating adjustment device 5 via the quick-release interface; adjust the horizontal adjustment device 4 to the initial angle (0° horizontal, 90° vertical), and tighten the manual screws or electromagnetic clips; install the lower section (removable part) of the chandelier housing 6. Hoisting and fixing: Fix the combined hanging bracket to the ceiling via the connecting vertical rod; remotely activate the telescopic mechanism 7 to expand the combined hanging bracket to the appropriate space width; tighten all expansion bolts and electromagnetic clips. Debugging and Acceptance: After powering on, the remote control activates the "Automatic Calibration Mode" with a single button. The system automatically adjusts the angles of each projector 3 to preset parameters and fine-tunes the image blending. The system checks the image coverage and synchronization accuracy; after confirming everything is correct, the chandelier casing 6 is sealed. The controller synchronously adjusts the horizontal deflection angle and vertical rotation angle of multiple projectors 3 to adjust the horizontal coverage and calibrate the vertical tilt angle, enhancing adjustment flexibility: supporting stepless adjustment of ±30° horizontally and 360° vertically to adapt to complex projection needs; ensuring seamless image blending, with a multi-projector 3 angle synchronization error ≤0.5° and a splicing gap <1mm, improving the immersive experience. The controller's built-in adjustment parameters utilize existing software design, a mature technology, and will not be elaborated upon. The projection angle is automatically adjusted through preset parameters, reducing manual debugging workload. The controller drives the electromagnetic latch to fix the adjusted projector 3 in place. This invention is applicable not only to immersive audio-visual spaces but also to virtual reality exhibition halls, holographic stages, etc.

[0047] Based on the above technical solutions, in other embodiments, the combined hanging bracket can be replaced with a carbon fiber hanging bracket, the drive motor can be replaced with a servo motor adjustment, the chandelier housing 6 can adopt a magnetic adsorption housing, and the infrared sensor can be replaced with a lidar detection module. While maintaining the core functions, this significantly improves lightweighting, adjustment accuracy, and ease of maintenance. Although the cost is higher, it is suitable for high-end immersive scenarios. In another embodiment, the adjustment mechanism can be replaced with a ball joint adjustment device, the infrared sensor can be replaced with an ultrasonic sensor, and the power supply method can be a traditional power supply method.

[0048] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
