Description

Technical Field

[0001] This utility model relates to the field of projection lighting technology, and more specifically, to a projection structure that uses patterned light sheets to achieve multi-frame-rate animation effects. Background Technology

[0002] Projection lights, as an important visual display tool, are widely used in advertising, industrial signage, stage effects, and atmosphere creation. Traditional projection lights typically use one or more static light panels in the light source path, changing the projected content by switching between different light panels.

[0003] Common commercial products typically integrate only 4 or 8 LED slides. The patterns on these slides are mostly independent logos or textures, and the transition effects are still abrupt. They do not consider the continuity between "frames" from the source of the pattern design, and they lack a matching control system that can precisely control the display duration of each frame (i.e., each pattern). Therefore, they cannot achieve true multi-frame rate animation transition effects in essence. Of course, projectors can directly play animations, but that is by directly projecting video formats such as MP4 onto the display screen. However, such systems are complex, including image processing units, storage units, and high-resolution display units, resulting in high costs and high power consumption. Moreover, their core components are not suitable for industrial projection scenarios that require simple structures, are cost-sensitive, and need long-term stable operation. Utility Model Content

[0004] The purpose of this invention is to address the current limitations of complex projection structures that restrict projection to static or abrupt image switching, thus preventing the achievement of smooth, fluid, and customizable animation effects.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A projection structure that uses patterned light sheets to achieve multi-frame-rate animation effects includes a housing and further includes: An optical component, disposed inside the housing, for forming and projecting light; The drive assembly includes a motor disposed inside the housing, a carrier portion disposed at the output end of the motor, and a control motherboard disposed inside the housing for controlling the start, stop and speed of the motor. Multiple light sheets are equidistantly distributed along the axis of the carrier at its top edge, and the patterns of two adjacent light sheets have visual continuity.

[0006] As a preferred technical solution of this application, the driving component further includes a motor plate fixed on the housing, the motor is fixed on the motor plate, and the motor plate has a light-transmitting hole, the diameter of which is adapted to the size of the light-transmitting area of ​​a single lamp sheet.

[0007] As a preferred technical solution of this application, the carrier part includes a rotating disk disposed on the motor output shaft, and a plurality of lamp sheets are evenly arranged circumferentially on the rotating disk.

[0008] As a preferred technical solution of this application, the rotating disk is provided with a plurality of lamp holders for mounting and fixing lamp sheets.

[0009] As a preferred technical solution of this application, the optical component includes an LED bead disposed inside the housing as a light source and a lens disposed at the projection end of the housing for focusing projection.

[0010] As a preferred technical solution of this application, a heat sink is provided at the end of the housing away from the lens.

[0011] As a preferred technical solution of this application, the number of light panels is at least 14.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model employs at least 14 light sheets with visually coherent patterns, combined with a drive component that allows for precise speed control. This enables the static light sheets to switch continuously and rapidly at a frame rate higher than the persistence of vision, thus creating a smooth dynamic animation in the human eye. Unlike existing technologies that can only achieve static patterns or abrupt pattern switching, this invention achieves true animation playback on a simple light sheet projection structure, thereby enriching the projection's expressive power.

[0013] 2. This invention combines a mechanical structure (rotating disk / carrier, lamp sheet) with basic electronic control (motor, motherboard), eliminating the need for expensive and sophisticated electronic components such as complex video decoding chips, high-resolution displays, or large-capacity memory. This simplifies the overall system structure, significantly reduces manufacturing costs compared to digital projection equipment, and makes the mechanical structure more robust and durable with a low failure rate, making it particularly suitable for industrial environments, outdoor advertising, and other scenarios requiring long-term stable operation.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0017] like Figure 1 and Figure 2 As shown, this embodiment proposes a projection structure that achieves multi-frame-rate animation effects using patterned light sheets. It includes a housing 4, an optical component, a driving component, and light sheets 8. The optical component includes LED beads 3 disposed inside the housing 4 as a light source and a lens 10 disposed at the projection end of the housing 4 for focusing the projection. The driving component includes a motor 5 disposed inside the housing 4, a carrier part disposed at the output end of the motor 5, and a control motherboard 2 disposed inside the housing 4 for controlling the start, stop, and speed of the motor 5. Multiple light sheets 8 are equidistantly distributed along the axis of the carrier part at its top edge, and the patterns of two adjacent light sheets 8 have visual continuity. The light emitted by the optical component can only pass through one light sheet 8 aligned with the light path and be projected at a time. By controlling the movement speed of the carrier part 9 through the control motherboard 2, multiple light sheets 8 are aligned with the light path sequentially and intermittently, thereby projecting a continuous animation effect. When single-frame projection is required, the system is powered on, and the control motherboard 2 starts. The user can issue commands through external signals or preset programs to control the motherboard 2 to drive the motor 5 to start working. The LED beads 3 in the optical components emit light, and the light is emitted. The drive components drive the carrier to move, so that only one of the multiple LED sheets 8 is precisely aligned with the light-transmitting hole 601 on the motor board 6, thus being located in the projection light path. The light passes through this light-transmitting hole 601 and the currently aligned LED sheet 8, focusing the star pattern on the LED sheet through the lens 10 and projecting it onto the external screen. The other LED sheets 8 are misaligned and cannot display the pattern, thus forming a static, single-frame projection image.

[0018] When frame sequence switching and animation generation are required, the control motherboard 2 drives the carrier unit to move continuously by precisely controlling the speed and stepping of the motor 5. This causes the current light sheet 8 to leave the light path, while the next light sheet 8 immediately enters and aligns with the light-transmitting hole 601. Since all light sheets 8 are mounted on the carrier unit around the central axis, and the patterns on adjacent light sheets 8 have visual continuity—for example, the position of a star only moves slightly between adjacent frames—when they pass through the light path sequentially and intermittently at a sufficiently fast speed, typically higher than 24 frames per second, a continuous pattern change is presented on the projection surface, frame by frame. The control motherboard 2's control of the motor 5 speed is key to achieving multi-frame rate: through programming, the duration of each light sheet's stay in the light path can be precisely set. The faster the speed, the shorter the single-frame display time, and the faster the animation rhythm; conversely, the animation rhythm slows down. This achieves an adjustable multi-frame rate animation effect. Therefore, the persistence of vision in the human eye automatically connects this series of rapidly changing, continuous static patterns, forming a smooth and coherent dynamic animation sensation in the brain, such as seeing a star smoothly light up along a circular trajectory.

[0019] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the driving component further includes a motor plate 6 fixed on the housing 4, a motor 5 fixed on the motor plate 6, and a light-transmitting hole 601 opened on the motor plate 6. The aperture of the light-transmitting hole 601 is adapted to the light-transmitting area size of a single lamp sheet 8. The carrier unit includes a rotating disk 9 mounted on the output shaft of the motor 5, and multiple lamp pieces 8 are evenly arranged circumferentially on the rotating disk 9; The motor 5 drives the rotating disk 9 to rotate, and the light emitted by the LED beads 3 shines from top to bottom. At this time, most of the LED sheets 8 are blocked by the solid part of the motor plate 6 because they are not aligned with the light-transmitting hole 601, and the light cannot pass through. Only when a certain LED sheet 8 moves with the rotating disk to a specific position, so that its effective light-transmitting area completely overlaps with the light-transmitting hole 601, is the light path momentarily "opened", and the transmitted light forms a complete pattern with clear boundaries and no interference. As soon as the previous LED sheet 8 moves out of the range of the light-transmitting hole 601, the light path is instantly cut off; then, the next LED sheet 8 immediately enters and is precisely aligned with the light-transmitting hole 601, and the light path is opened again, displaying the next frame of the pattern. In this way, a continuous and related pattern can be formed.

[0020] Furthermore, the rotating disk 9 is provided with multiple lamp holders 7 for mounting and fixing the lamp sheet 8; the lamp holders 7 can fix the lamp sheet 8 and prevent the lamp sheet 8 from shaking and affecting the projection effect.

[0021] Furthermore, a heat sink 1 is provided at the end of the housing 4 away from the lens 10; when the internal temperature of the housing 4 rises due to prolonged use of the projection device, the heat sink 2 can quickly dissipate the heat, thereby improving the protection effect on the internal components of the housing 4.

[0022] It should be noted that the number of light sheets 8 is at least 14; the number of star patterns on the 14 light sheets 8 is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14 respectively. The number of light sheets 8 is tentatively set at 14, based on the current frame rate of human visual nerve recognition. Of course, a number greater than 14 can also be used, which is also within the scope of this patent protection. Then, the rotating disk 9 drives the light sheet holder 7 to rotate. We are not limited to rotational motion; linear motion can also achieve the same effect.

[0023] In addition, the pattern of the light sheet 8 is not limited to star patterns. Any other pattern that can achieve a continuous effect, with the emphasis on continuity, is within the scope of protection of this patent.

[0024] The working principle of this invention is as follows: The starting motor 5 drives the rotating disk 9 to rotate, causing the LED beads 3 in the optical component to emit light. This light ensures that only one of the multiple LED sheets 8 is precisely aligned with the light-transmitting hole 601 on the motor plate 6, thus placing it in the projection light path. The light passes through this light-transmitting hole 601 and the currently aligned LED sheet 8, focusing the star pattern on that sheet through the lens 10 and projecting it onto an external screen. The remaining LED sheets 8 are misaligned and cannot display the pattern. As the current LED sheet 8 leaves the light path, the next LED sheet 8 immediately enters and aligns with the light-transmitting hole 601. Because all LED sheets 8 are mounted on the rotating disk 9 around a central axis, and the patterns on adjacent LED sheets 8 have visual continuity, a continuous series of pattern changes is presented on the projection surface, achieving an adjustable multi-frame rate animation effect. Therefore, the persistence of vision in the human eye automatically connects this series of rapidly changing, continuous static pattern images, forming a smooth and coherent dynamic animation sensation in the brain, such as seeing a star smoothly light up along a circular trajectory.

[0025] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
