Description

Technical Field

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

[0002] In modern stage performances, concerts, and large-scale events, lighting effects play a crucial role in creating atmosphere, highlighting key elements, and enhancing visual impact. To achieve a rich variety of lighting effects, traditional solutions typically require combining multiple single-function luminaires (e.g., LED pixel lights for ambient lighting, beam lights for creating sharp beam patterns, and scan lights for dynamic scanning). This approach has the following significant drawbacks:

[0003] 1. Complex installation and wiring: Multiple lighting fixtures need to be hung, positioned and wired separately, which not only increases the time and labor costs of on-site installation and debugging, but also results in numerous and messy cables, posing safety hazards, and is not conducive to quick disassembly and relocation during tours.

[0004] 2. Limited Dynamic Effects: While some existing integrated lighting fixtures incorporate some functions, they often suffer from complex structures or stiff effects in achieving a combination of dynamic changes in overall shape (such as the coordinated rotation of multiple light-emitting units) and precise pointing of local beams, making it difficult to achieve smooth, multi-dimensional composite dynamic lighting effects. Utility Model Content

[0005] 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 organically integrates multi-layer ring light emission, directional beam projection and overall low-speed rotation function, with a compact and stable structure, rich light effect layers and convenient and flexible control.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A stage effect lighting fixture includes a UFO-shaped lamp body, an electrical control box, a rotary drive mechanism, and a hanging structure; multiple UFO-shaped lamp bodies are evenly arranged vertically and connected end to end in sequence, with the topmost UFO-shaped lamp body rotatably mounted under the electrical control box and driven to rotate at low speed by the rotary drive mechanism located inside the electrical control box; a hanging structure is also installed on the top of the electrical control box.

[0008] As an improvement, a light strip is fitted and fixed to the side wall of the flying saucer lamp body.

[0009] As an improvement, a rotating shaft is fixed to the top wall of the topmost UFO-shaped lamp body and rotatably connected to the bottom wall of the electrical control box.

[0010] As an improvement, the rotary drive mechanism includes a drive motor, which is installed and fixed inside the electrical control box and is connected to the rotating shaft via a gear belt transmission.

[0011] As an improvement, the electrical control box is also equipped with a DMX512 signal interface, an RJ45 interface, a display control board, a Hall effect detection board, a control signal aviation interface, and a power interface.

[0012] As an improvement, the hanging structure includes a hook and a handle screw; after the hook is fixed to the top wall of the electrical control box, the handle screw is threaded into the screw hole reserved at the bottom of the hook and tightened to form a closed loop structure with the hook.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. This new type of luminaire perfectly integrates three major functional modules: ring-shaped surface light, directional beam, and overall rotation, into a single unit. A single luminaire can replace the effect achieved by combining multiple different luminaires in traditional solutions, greatly simplifying the system configuration. Through control, it can present both static layered colored light rings and dynamic, complex effects such as rotating beam forests and spiraling color changes. The richness and expressiveness of the lighting effects far surpass traditional distributed luminaire combinations. The unique low-speed rotation design of the layered luminaire body makes the luminaire itself a dynamic visual element. The rotational motion, combined with the programmed changes in the color, brightness, and beam opening and closing of each layer of light, can create dynamic lighting effects with strong visual appeal and a sense of space—something difficult to achieve with static or multi-lamp mechanical oscillation.

[0015] 2. This new type of structure allows for convenient hanging installation. Attached Figure Description

[0020] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model 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 utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. 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.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the stage effect lighting fixture disclosed in this utility model is based on the combination of a rotatable stacked light source and an integrated electrical control box.

[0023] I. Main Structure and Connections

[0024] The main body of the lamp is composed of five (adjustable number) identical UFO-shaped lamp bodies 1 stacked vertically. Each UFO lamp body 1 is roughly flat cylindrical or disc-shaped, with corresponding connecting structures (such as screw holes or clips) on its upper and lower ends. They are tightly fixed end to end by screws or quick-locking mechanisms to form a stable lamp body column.

[0025] The control box 2 is a sealed or semi-sealed enclosure located at the very top of the lamp column. A bearing seat is located at the center of the bottom wall of the control box 2, and a vertically upward rotating shaft 4 is fixed to the center of the top wall of the topmost UFO lamp body 1. The upper end of the rotating shaft 4 is inserted into the bearing seat on the bottom wall of the control box 2, achieving a rotatable connection. In this way, the entire lamp column (containing five UFO lamp bodies 1) can rotate freely relative to the control box 2.

[0026] II. Drive System

[0027] The rotary drive mechanism is installed inside the electrical control box 2. It mainly consists of a drive motor 5, a driving gear, a driven gear, and a synchronous toothed belt (the gears and belt are not shown in detail in the figure). The drive motor 5 is fixed inside the electrical control box 2, and its output shaft is fitted with the driving gear. The driven gear is fixed to the upper end or middle of the rotating shaft 4. The driving gear and the driven gear are connected by the synchronous toothed belt, transmitting the power of the drive motor 5 to the rotating shaft 4, thereby driving the entire lamp post to rotate. The drive motor 5 is preferably a stepper motor or a servo motor with an encoder to achieve smooth low-speed rotation and precise speed / position control. The Hall effect sensor board inside the electrical control box 2 cooperates with the magnet on the rotating shaft 4 to detect the number of rotations and angle in real time, providing closed-loop control or position feedback signals.

[0028] III. Optical System

[0029] On the annular sidewall of each UFO-shaped lamp body 1, a flexible LED light strip 3 is fitted, bonded, or clipped in, serving as the main annular light-emitting surface. The annular light strip 3 is composed of multiple RGB LED beads and can be independently controlled. Inside the lower cover of each UFO-shaped lamp body 1, eight beam assemblies are evenly embedded and fixed along the circumference. Each beam assembly includes a circuit board with high-brightness RGB LED beads and a front-mounted focusing lens. The optical design of the lens gives its emitted beam a narrow divergence angle and projects it obliquely downward at approximately a 35-degree angle (relative to the vertical axis of the lamp). These eight beams form a clear beam array in the space below the lamp body.

[0030] IV. Electrical and Control Systems

[0031] The electrical control box 2 is the "brain" of the entire lighting fixture. It integrates:

[0032] Display control board: The core control unit is responsible for receiving external control signals, decoding them, generating drive signals, and controlling the LEDs of each layer of light strip 3, the LEDs of each beam component, and the drive motor 5 respectively.

[0033] Signal interfaces include standard DMX512 input / output interfaces, RJ45 Ethernet interfaces, and reliable aviation plug interfaces, providing a variety of signal access methods.

[0034] Power interface and processing module: Converts externally input AC or DC power into the operating voltage required by each component.

[0035] All the cables of the light strips 3 and beam components inside the UFO light body 1 are gathered at the top UFO light body 1 through the channels reserved at the interlayer connection, and then connected to the electrical control box 2 through the cavity inside the rotating shaft 4 or the slip ring next to it (to ensure that the wires do not break during rotation).

[0036] V. Installation and Hanging Structure

[0037] A sturdy hanging hook 6 is welded or bolted to the outer side of the top wall of the electrical control box 2. The main body of the hanging hook 6 is U-shaped or similar in structure, with a screw hole machined below its open end. The screw portion of the handle screw 7 is screwed into this screw hole. When the light fixture needs to be suspended, the hook portion of the hanging hook 6 is hung on the U-shaped bracket of the truss or hanging rod, and then the handle screw 7 is tightened until the end of the screw abuts or approaches the truss, thus forming a closed force ring with the hook portion of the hanging hook 6, firmly locking the light fixture to the suspension point with extremely high safety. The head of the handle screw 7 is designed for easy hand tightening, allowing for quick tightening or loosening without tools.

[0038] In use, this new type of lighting fixture is suspended above the stage at a predetermined position via a hanging structure. The power cord and DMX signal cable (or network cable) are connected to the control box 2.

[0039] This invention achieves significant improvements in the functionality, artistry, reliability, and ease of use of stage lighting equipment through its ingenious mechanical structure design, highly integrated electronic control system, and advanced light source technology.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. 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.
