Description

Technical Field

[0001] This invention relates to the field of light and shadow technology, and in particular to a laser light image interactive performance device. Background Technology

[0002] Currently, laser light shows are an important form of outdoor nighttime performance used in theme parks and scenic areas, enhancing the visitor experience.

[0003] Existing laser light shows typically use water mist, haze, and smoke (as well as natural fog, rain, dust, and snow) as mediums to outline simple lines and shapes, presenting this part of the performance to the audience from a distance. This results in a poor interactive experience between the audience and the laser light images, making it difficult for the audience to receive the emotional content they convey. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a laser light image interactive performance device, which aims to enhance the interaction between tourists and laser light images, and allow tourists to understand the performance story more intuitively.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a laser light image interactive performance device, including a medium and a light group disposed above the medium. The medium is made of fabric and is located in the seating area of ​​the audience. The light group includes at least two laser lights, the projection direction of the laser lights is towards the medium, and the image presented by the laser lights is projected onto the medium and displayed.

[0006] Furthermore, all the laser lights in the same light group are arranged horizontally side by side relative to the medium.

[0007] Furthermore, the lamp assembly is suspended vertically above the medium.

[0008] Furthermore, it also includes a lamp post for mounting the lamp assembly, with the laser light suspended from the lamp post.

[0009] Furthermore, the laser light is either fixed or movable relative to the light pole.

[0010] Furthermore, the multiple sets of lamps are connected using a grid splicing method.

[0011] Furthermore, it also includes a display stand with the seating area, on which the medium is laid flat.

[0012] Furthermore, the display stand can be a table, stool, or shelf.

[0013] Furthermore, it also includes a lighting control card, a switch, a lighting console, and a central control device. The lighting group is connected to the lighting control card. During debugging, the lighting control card is connected to the lighting console through the switch. During operation, the lighting control card is connected to the central control device through the switch.

[0014] Furthermore, it also includes a signal amplifier, through which the lamp group is connected to the lamp control card.

[0015] The advantages of this invention compared to existing technologies are as follows: A laser-based interactive performance device includes a medium and a light assembly positioned above the medium. The medium is made of fabric and is located in the seating area for the audience. The light assembly includes at least two laser lights, with the projection direction of the laser lights facing the medium. The image projected by the laser lights is projected onto the medium and displayed. By placing the medium in the seating area and positioning the light assembly above it, this invention allows the laser light radiation to radiate over a wide area, avoiding direct contact with the audience's eyes. Furthermore, by using a curtain as a medium, it can suppress laser reflection interference, increase image clarity, and allow the image to be presented to the audience in close proximity. This not only allows for photo opportunities but also enables the audience to interact with the projected content.

[0016] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, it can be implemented according to the contents of the specification.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0021] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0026] like Figures 1 to 5 As shown, this embodiment of the invention provides a laser light image interactive performance device, including a medium 1 and a light group 2 disposed above the medium 1. The medium 1 is made of fabric and is located in the seating area of ​​the audience 100. The light group 2 includes at least two laser lights 21. The projection direction of the laser lights 21 is towards the medium 1, and the image presented by the laser lights 21 is projected onto the medium 1 and displayed.

[0027] Medium 1 is made of fabric, which, compared to other materials such as glass and metal, reflects laser light relatively weakly, effectively suppressing laser reflection interference and thus increasing image clarity. Specifically, white non-woven fabric can be used as the material for Medium 1, or custom-made fabrics and functional flame-retardant and light-absorbing materials can be selected to effectively reduce the impact of strong laser light on the image, making viewing more comfortable.

[0028] The light group 2 includes at least two laser lights 21, which project towards the medium 1, thereby projecting the image onto the medium 1 and displaying it.

[0029] like Figure 1 and Figure 2 As shown, in practical applications, a performance venue is generally equipped with multiple sets of lights 2. The multiple sets of lights 2 are geometrically distributed in front of the performance stage 200. Each set of lights 2 corresponds to a medium 1. The images presented by each set of lights 2 on the corresponding medium 1 can be the same or different. Of course, in order to ensure the consistency of the performance presentation, all mediums 1 in the same performance venue present the same images.

[0030] First, media 1 is placed in the seating area of ​​audience member 100, and light group 2 is positioned above media 1. This ensures that the laser light 21's radiation covers a wide area and avoids direct sunlight on audience member 100's eyes, guaranteeing their viewing safety. Second, the use of fabric material for media 1 effectively suppresses laser reflection interference, increasing image clarity. Furthermore, audience member 100 can closely surround and view the projected content, not only taking photos but also interacting with it. For example, in some interactive performances, audience member 100 can use handheld sensors to interact with the projected image on media 1, changing the image's color, shape, etc., greatly enhancing their sense of participation and experience.

[0031] In one embodiment, all laser lights 21 in the same light group 2 are arranged horizontally side by side relative to the medium 1, and the interval between two adjacent laser lights 21 is consistent.

[0032] The horizontal arrangement of laser lights 21 in the same light group 2 ensures uniform illumination of the medium 1. Because all laser lights 21 are at the same horizontal level and arranged parallel to each other, the light spots they project onto the medium 1 are evenly distributed, avoiding areas that are too bright or too dark, thus guaranteeing the uniformity and clarity of the projected image. For example, when displaying a richly colored image, the uniform light distribution ensures that the colors in all parts of the image are accurately and vividly presented, providing a consistent visual experience for the viewer 100 regardless of the viewing angle.

[0033] In one embodiment, the lamp assembly 2 is vertically suspended above the medium 1. This vertical suspension ensures that the laser light is incident perpendicularly onto the medium 1, minimizing image distortion caused by tilted light. Taking the projection of a standard circular pattern as an example, the perpendicularly incident light guarantees that the circular pattern appears perfectly circular on the medium 1. Regardless of the viewing angle, the shape and proportions of the pattern will not be distorted, thus ensuring image accuracy and visual appeal. Simultaneously, the vertical suspension method results in a more concentrated light distribution, creating a brighter light spot on the medium 1, which improves image clarity and color saturation, allowing the viewer to see the projected content more clearly.

[0034] In one embodiment, such as Figure 1 As shown, the laser light interactive performance device also includes a light pole 4 for mounting the light group 2, with the laser light 21 suspended on the light pole 4.

[0035] The light pole 4 can be installed in two common ways: ground fixing or ceiling suspension. If ground fixing is used, a metal base plate with evenly distributed mounting holes can be welded to the bottom of the light pole 4. The base plate is then fixed to the ground of the performance venue using expansion bolts, ensuring the light pole 4 is stable and upright. At the top of the light pole 4, multiple hooks or mounting brackets are installed for suspending the laser lights 21. The laser lights 21 are suspended from the hooks using matching metal chains or high-strength ropes. The position and angle of the laser lights 21 are adjusted so that their projection direction is accurately directed towards the medium 1 below. If ceiling suspension is used, the lower end of a suspension rope is connected to the light pole 4, and the upper end of the rope is fixedly connected to the ceiling.

[0036] By mounting the laser lamp 21 on the lamp post 4, the lamp post 4 can raise the laser lamp 21 to a certain height, ensuring that the light from the laser lamp 21 can cover a larger area of ​​the medium 1, thus expanding the projection coverage area. At the same time, the lamp post 4 provides stable support for the laser lamp 21, reducing interference from external factors and ensuring the stability of the laser lamp 21 during operation. This ensures stable projection image quality and prevents image jitter or blurring due to the shaking of the laser lamp 21.

[0037] In one embodiment, the light pole 4 can be raised and lowered using an electric lifting device. When it is necessary to adjust the height of the light group 2, a command is sent through a remote control or control software, and the electric lifting device can drive the light pole 4 to rise or fall, thereby flexibly adjusting the distance between the light group 2 and the medium 1 to meet the needs of different performance scenarios.

[0038] In one embodiment, the suspension portion of the light assembly 2 is equipped with a rotatable joint, allowing each laser light 21 to be adjusted at a certain angle within the vertical plane. By controlling the rotatable joint, the laser light 21 can swing slightly in the vertical direction, causing the light projected onto the medium 1 to swing accordingly, thereby creating a dynamic effect of swaying light and shadow, adding more interest and vividness to the performance.

[0039] In one embodiment, the laser light 21 is either fixed or movable relative to the lamp post 4. When movable, a sliding rail can be used. Specifically, a linear sliding rail adapted to the length of the lamp post 4 is installed on the lamp post 4. The sliding rail can be made of aluminum alloy to reduce weight while ensuring strength. The laser light 21 is mounted on a specially designed slider, which cooperates with the sliding rail and can slide freely on the rail. By driving the slider to move on the sliding rail with a motor, the position of the laser light 21 on the lamp post 4 can be changed, thereby adjusting the spacing between adjacent laser lights 21 in the same lamp group 2. The motor can be operated via a remote control or control system. When it is necessary to adjust the illumination range of the laser light 21, the operator can send a command, and the motor will drive the slider to move, causing the laser light 21 to move closer to or further away from the medium 1, thereby changing the size and position of the image projected onto the medium 1.

[0040] In one embodiment, such as Figure 3 and Figure 4 As shown, multiple light groups 2 are connected using a 300 grid splicing method.

[0041] The lights are connected using a 300-grid splicing method, ensuring consistency in the light show content within the same venue, enhancing image clarity, and effectively expanding the laser projection area for a more vivid visual experience. In practical applications, different light groups can be connected using metal connectors and cables. Figure 3 This is a schematic diagram of the assembly process. Figure 4 This is a schematic diagram of the completed assembly.

[0042] In one embodiment, such as Figure 1 and Figure 2 As shown, the laser light interactive performance device also includes a display platform 3 with a seating area, on which the medium 1 is laid flat. The display platform 3 can be a table, stool, or shelf. The display platform 3 makes it easier to present the image to the audience 100 at close range, enhancing the audience 100's experience.

[0043] In one embodiment, such as Figure 5 As shown, the laser light image interactive performance device also includes a light control card 6, a switch 7, a light control console 8, and a central control device 9. The light group 2 is connected to the light control card 6. During debugging, the light control card 6 is connected to the light control console 8 through the switch 7. During operation, the light control card 6 is connected to the central control device 9 through the switch 7.

[0044] The lighting control card 6 needs to be selected based on the size of the lighting group 2 and the type of laser light 21. The switch 7 is used for fast data transmission and exchange, ensuring that control signals can be efficiently transmitted between various devices. The ports of the switch 7 are connected to the lighting control card 6, the lighting console 8, and the central control device 9, respectively. Through proper configuration of network parameters, fast data routing and forwarding are achieved.

[0045] The lighting control console 8 is mainly used during the device commissioning phase. Technicians can use it to perform detailed parameter adjustments and tests on the light group 2. Common lighting control consoles 8 have an intuitive user interface, such as an LCD screen and operation buttons. During commissioning, the lighting control card 6 is connected to one port of the switch 7 via a network cable, and the lighting control console 8 is also connected to the other port of the switch 7. Technicians input various commands on the lighting control console 8, such as adjusting the brightness of a specific laser light 21 or changing the color combination of the light group 2. These commands are transmitted to the lighting control card 6 via the switch 7, and the lighting control card 6 then controls the corresponding laser light 21 according to the received commands.

[0046] The central control device 9 plays a core control role during the performance operation. The central control device 9 can be a high-performance computer equipped with dedicated lighting control software. During operation, the central control device 9 is also connected to the lighting control card 6 via the switch 7. Before the performance, the operators import a carefully choreographed performance program into the control software of the central control device 9. This program includes various effects of the laser lights 21 throughout the performance, such as the flashing rhythm, color gradient sequence, and pattern switching timing. After the performance begins, the central control device 9 sends a series of control commands to the lighting control card 6 via the switch 7 according to the preset program. The lighting control card 6 precisely controls the state of each laser light 21 based on these commands, thus achieving a spectacular interactive laser light 21 video performance.

[0047] In one embodiment, such as Figure 5 As shown, the laser light interactive performance device also includes a signal amplifier 5, and the light group 2 is connected to the light control card 6 through the signal amplifier 5.

[0048] In terms of connection method, the signal line from the lighting control card 6 is first connected to the input terminal of the signal amplifier 5. The input terminal of the signal amplifier 5 is designed with a standard interface, such as a BNC interface or an RJ45 interface, which can be matched with the interface of the output signal line of the lighting control card 6 to ensure the stability of the connection and the reliability of signal transmission. Next, multiple sets of signal lines are led out from the output terminal of the signal amplifier 5 and connected to multiple groups of lights 2 respectively.

[0049] The application of signal amplifier 5 effectively solves the signal attenuation problem caused by excessive transmission distance or environmental interference. It can amplify the weak control signal sent by the lighting control card 6 to an intensity sufficient to drive each laser lamp 21 in the lamp group 2 to work normally, ensuring that the laser lamp 21 can accurately execute the various commands sent by the lighting control card 6.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
