Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, specifically to a stage effect lighting fixture. Background Technology

[0002] Current stage lighting technology typically requires the simultaneous deployment of multiple functional lighting fixtures, such as pixel lights, beam lights, and scanning lights, to achieve rich variations in lighting effects. This distributed layout not only increases the number of lighting fixtures, complicates installation structures, and cumbersome wiring, but also increases equipment costs and control difficulty. Especially in large-scale performances or stage scenes, the hanging, adjustment, and synchronous control of lighting fixtures become technical bottlenecks.

[0003] Currently, most swing stage lighting fixtures on the market are large-scale professional equipment with bulky structures, inconvenient hoisting, and difficulty in achieving high-density array arrangements; while lightweight lighting fixtures generally have single functions and lack flexible and precise angle adjustment capabilities, failing to meet the refined requirements of modern stages for lighting direction, coverage, and dynamic effects. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a stage effect lighting fixture that is compact in structure, easy to hoist, has two-axis independent swing function, integrates pixel display and multi-beam effect, and is suitable for large-scale array arrangement.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A stage effect lighting fixture includes a hexagonal lamp body, a transfer box, an X-axis swing drive mechanism, a Y-axis swing drive mechanism, a central control box, and a hanging structure. After the transfer box and the central control box are arranged vertically, the transfer box is located between the two and is rotatably connected to both. The hexagonal lamp body is driven to swing back and forth along the X-axis direction by the X-axis swing drive mechanism installed on itself. The transfer box is driven to swing left and right along the Y-axis direction by the Y-axis swing drive mechanism installed on the central control box. A hanging structure is fixed on the upper side of the central control box.

[0007] As an improvement, after the X-direction motor box is fixed on the top surface of the hexagonal lamp body, an X-direction rotating shaft is fixed on the side of the transfer box and rotatably connected to the side wall of the X-direction motor box.

[0008] As an improvement, the X-axis swing drive mechanism includes an X-axis motor, which is installed and fixed in the X-axis motor housing, and the output shaft is fixedly connected to the X-axis rotating shaft.

[0009] As an improvement, an X-axis swing limiting post is fixed on the side wall of the X-axis motor housing, and an X-axis swing limiting hole is pre-reserved on the side wall of the transfer box. The X-axis swing limiting hole has an arc-shaped slot structure. This can limit the range of X-axis forward and backward reciprocating swing.

[0010] As an improvement, after the Y-axis motor box is fixed on the bottom wall of the central control box, a Y-axis rotating shaft that is rotatably connected to the side wall of the Y-axis motor box is fixed on the side of the transfer box.

[0011] As an improvement, the Y-axis swing drive mechanism includes a Y-axis motor, which is installed and fixed in the Y-axis motor housing, and the output shaft is fixedly connected to the Y-axis rotating shaft.

[0012] As an improvement, a Y-axis swing limiting post is fixed on the side wall of the Y-axis motor housing, and a Y-axis swing limiting hole is pre-reserved on the side wall of the transfer box. The Y-axis swing limiting hole has an arc-shaped slot structure. This can limit the range of Y-axis reciprocating swing.

[0013] As an improvement, the hanging structure includes a hanging rod, a hook, and a handle screw. The bottom of the hanging rod is fixed to the upper side of the central control box, and the top is fixed to the hook. The handle screw is threaded into a pre-drilled hole at the bottom of the hook and tightened, forming a closed-loop structure with the hook. This allows for convenient and secure hanging installation of this new type of structure.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. This new type of lighting fixture uses lightweight materials and a modular design, reducing the overall weight by more than 30% compared to traditional swing lamps. The hanging structure adopts a closed-loop locking design with anti-slip treatment, ensuring stable installation. It is particularly suitable for high-altitude and multi-lamp array installations, significantly reducing installation difficulty and time costs.

[0016] 2. This new type of lamp body can independently swing around the two axes within a range of ±30° by using X-axis and Y-axis swing mechanisms in conjunction with high-precision stepper motors and angle sensors. The angle adjustment accuracy reaches 0.1°, and the response is fast, which can meet the high-precision requirements of beam direction, tracking lighting and dynamic scanning on the stage.

[0017] 3. This new type of display combines hexagonal pixel display with six independent beam modules, which can present delicate pixel patterns and dynamic effects, and output multiple independent and controllable high-brightness beams, realizing the fusion of pixel and beam expression, greatly expanding the artistic expression dimension of stage lighting, and reducing the types and number of lighting fixtures.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Overall structure description:

[0027] like Figures 1 to 5 As shown, the stage effect lighting fixture provided by this utility model is a multi-functional integrated device that combines two-axis swing function, pixel display, and independent beam effects. Its core structure, from top to bottom, mainly includes: a hanging structure, a central control box 3, a transfer box 2, and a hexagonal lamp body 1. The components work together through precise mechanical connections and electrical control to achieve easy installation, accurate swing, and rich light effect output.

[0028] Specific implementation of the suspension structure:

[0029] The suspension structure is the connecting component between the lighting fixtures and the stage truss or rigging, and its core requirements are safety, stability, and convenience. Specifically, the bottom of the suspension rod 14 is firmly fixed to the mounting flange on the top of the central control box 3 by four hexagonal bolts. The suspension rod 14 is made of high-strength 6061 aluminum alloy through a cold-drawing process, and has a hollow tubular structure, which achieves lightweight while ensuring support strength.

[0030] The hook 15 is screwed into the male thread at the top of the hanging rod 14 via its internal thread at the bottom, and a nylon lock nut is installed at the connection to prevent loosening due to vibration. The main body of the hook 15 is made of forged stainless steel, and the top is designed with an inwardly curved arc-shaped hanging groove. A 3 mm thick anti-slip rubber pad is attached to the inner surface of the hanging groove. This rubber pad has a high coefficient of friction and can effectively prevent the lamp from sliding on the hanging rod.

[0031] To ensure a safe installation, a threaded through hole is horizontally provided on the lower side of the hook 15. During installation, after hooking the hook 15 onto the boom, screw the handle screw 16 into the threaded hole until the screw head is firmly against the lower surface of the boom. The end of the handle screw 16 is designed with a smooth, rounded head to avoid scratching the boom. After tightening, the hook 15, handle screw 16, and boom together form a mechanical closed loop, fundamentally eliminating the risk of the light fixture accidentally detaching.

[0032] Implementation of the central control box and its internal components:

[0033] The central control box 3 is the "brain" and control hub of the entire lighting fixture. Its outer shell is welded from 1.2mm thick aluminum alloy sheet with an anodized finish, combining strength, lightweight, and excellent electromagnetic shielding. The front panel of the central control box 3 integrates multiple functional interfaces: a power input socket with a waterproof cover, supporting AC100-240V wide voltage input; a five-pin DMX512 signal input / output socket; an RJ45 Ethernet interface; and a micro USB interface for local debugging. A 2.4-inch TFT LCD screen is also located in the center of the panel, which can display real-time status information such as the lighting fixture's IP address, DMX address, temperature, and motor angle.

[0034] Opening the cover of the central control box 3 reveals its clear internal layout. A 200W switching power supply module is fixedly mounted at the rear, providing power to the entire system. A main control board is installed at the front. This board uses an ARM Cortex-M4 series microprocessor as its core, integrating a DMX512 signal decoding chip, an Ethernet PHY chip, and a 2.4G wireless communication module. The control board is connected to another dedicated motor drive board via a ribbon cable. The motor drive board uses a dual H-bridge driver chip, providing precise current and pulse control for the X-axis motor 6 and the Y-axis motor 11. The bottom and sides of the central control box 3 have elongated ventilation holes, with corresponding 4020 silent fans installed inside. These fans intelligently adjust their speed based on temperature sensor feedback, ensuring that the electronic components operate at a suitable temperature.

[0035] Specific implementation and linkage of the two-axis swing mechanism:

[0036] The two-axis swing mechanism is the key to realizing multi-angle illumination of the lamp. Its core is the X-axis swing drive mechanism and the Y-axis swing drive mechanism, which achieve motion decoupling and transmission through the transfer box 2.

[0037] Implementation of Y-axis oscillation (left and right oscillation):

[0038] The Y-axis oscillation drive mechanism is responsible for driving the entire lamp body (including the transfer box 2 and the hexagonal lamp body 1) to oscillate left and right around the Y-axis. A Y-axis motor housing 9 is fixed to the center of the bottom of the central control box 3 by screws. The Y-axis motor housing 9 is made of engineering plastic and houses the Y-axis motor 11. The Y-axis motor 11 is a 42-stepper motor with a 256 microstepping driver, and its output shaft is connected to one end of the Y-axis rotating shaft 10 through a rigid diaphragm coupling. The Y-axis rotating shaft 10 is horizontally positioned, and its other end passes through a precision ball bearing on the side wall of the Y-axis motor housing 9 and extends into a pre-set bearing seat on the side wall of the transfer box 2 for fixation. Therefore, when the control signal drives the Y-axis motor 11 to rotate, the torque is directly transmitted to the transfer box 2 through the Y-axis rotating shaft 10, causing it and all the components below it to rotate around the Y-axis.

[0039] Limiting and Protection Mechanism: A stainless steel Y-axis swing limiting post 12 is vertically fixed on the side wall of the Y-axis motor housing 9 near the transfer box 2. Correspondingly, an arc-shaped through slot with a central angle of 60 degrees, i.e., a Y-axis swing limiting hole 13, is formed at the position of the transfer box 2 corresponding to the limiting post 12. The end of the Y-axis swing limiting post 12 extends into this arc-shaped slot. When the Y-axis motor 11 drives the transfer box 2 to swing, the Y-axis swing limiting post 12 slides within the Y-axis swing limiting hole 13. The two ends of the arc-shaped slot are the mechanical limit positions of the swing (±30°), effectively preventing excessive rotation caused by program errors or sensor malfunctions, which could damage the wiring or structure.

[0040] Implementation of X-axis oscillation (back-and-forth oscillation):

[0041] The X-axis oscillation drive mechanism drives the hexagonal lamp body 1 to oscillate back and forth around the X-axis relative to the transfer box 2. An X-axis motor housing 4 is fixed to the top center of the hexagonal lamp body 1 with screws. Its internal structure is similar to the Y-axis mechanism, housing an X-axis motor 6 of the same specifications. The output shaft of the X-axis motor 6 is also connected to the X-axis rotating shaft 5 via a coupling. The X-axis rotating shaft 5 is horizontally arranged and perpendicular to the spatial orientation of the Y-axis rotating shaft 10. Its other end passes through a bearing on the side wall of the X-axis motor housing 4 and connects to a bearing seat on the other side wall of the transfer box 2 (perpendicular to the side wall where the Y-axis rotating shaft 10 is located).

[0042] Limiting and protection mechanism: Similarly, an X-axis swing limiting post 7 is fixed on the side wall of the X-axis motor box 4, and an arc-shaped X-axis swing limiting hole 8 is opened at the corresponding position of the transfer box 2. Its principle and function are exactly the same as the Y-axis limiting mechanism, which limits the pitch angle of the hexagonal lamp body to within ±30°.

[0043] Through the above design, the movements of the X-axis and Y-axis are independent of each other and are coordinated and controlled by the control module in the central control box 3, which can realize the precise positioning of the lamp body in any direction within the hemispherical space.

[0044] Lamp components and lighting effects implementation:

[0045] The hexagonal lamp body 1 is the output terminal for light effect. Its shell is made of flame-retardant ABS plastic and is integrally molded by injection molding. It has a regular hexagonal disc structure and the surface is treated with matte paint.

[0046] Pixel Effect Light Section: At the center of the bottom of the light body, there is a hexagonal recess that matches the shape of the outer casing. Embedded within this recess is a hexagonal LED pixel display panel. This display panel uses SMD5050RGB full-color LEDs as pixels, with a pixel center-to-center spacing of 10 mm. The entire panel has approximately 600 pixels, controlled by a constant current point-to-point refresh mechanism via an LED driver chip. This pixel panel can display static logos, text, and geometric patterns via control signals, as well as dynamic effects such as flowing water, gradients, and color diffusion. Pixel color and brightness are independently programmable.

[0047] Beam Module Section: At each of the six corners of the hexagonal lamp body 1, there is an independent mounting station. Each station houses a set of beam modules. Each beam module is essentially a small optical engine, with six independent beam modules mounted side-by-side inside its housing. At the core of each beam module is a 10W high-power monochrome LED (selectable colors include white, red, green, blue, and amber). The back of the LED is flush against the aluminum substrate and contacts the heat sink fins of the housing via thermal grease. A replaceable focusing lens is mounted in front of the LED; the beam angle can be adjusted by rotating the lens sleeve, ranging from a narrow focus of 5 degrees to a soft beam of 25 degrees. The power supply and control circuits for the six beam modules are independent, connected to a distribution board inside the lamp body, and ultimately converged to the central control box 3. Therefore, individual switching, dimming (0-100%), and high-speed strobeing of all 36 beam modules can be achieved, creating strong beam effects such as cross, scanning, and strobe arrays.

[0048] In summary, this utility model, through its innovative mechanical structure, highly integrated electronic control, and multifunctional optical design, successfully achieves the goals of multi-functionality, precise control, lightweight and stability, and suitability for large-scale array deployment, providing a highly efficient, economical, and expressive solution for modern stage lighting.

In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
