[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1, please refer to Figure 1-4 This utility model discloses a 3D projection lamp, including a projection lamp body 1. The projection lamp body 1 includes a lamp housing 11. An angle-adjustable base 16 is provided at the bottom of the lamp housing 11. A lamp assembly 13 is provided inside the lamp housing 11. The lamp assembly 13 includes a lamp plate 131. A film body 134 is provided on one side of the lamp plate 131 and a motor 139 is provided on the other side. The output end of the motor 139 extends through the lamp plate 131 to one side of the film body 134 and is provided with a six-in-one lens 138.

[0025] Specifically, a film holder 133 is provided on one side of the lamp panel 131, and the film body 134 is embedded inside one side of the film holder 133. An arc-shaped lens 132 is provided inside the other side of the film holder 133. The arc-shaped lens 132 is coaxially opposite to the LED beads on one side of the lamp panel 131. A film pressing ring 135 is provided on the side of the film holder 133 away from the arc-shaped lens 132. A film pressing plate 136 for pressing the film pressing ring 135 is also provided on one side of the film holder 133. An arc-shaped lens 137 is provided on the side of the film pressing plate 136 away from the film holder 133. The six-in-one lens 138 is located on the side of the arc-shaped lens 137 away from the film pressing plate 136.

[0026] In this implementation scheme, curved lens 132 is used to initially focus the light, curved lens 137 further diffuses the light and enhances the depth of field, film body 134 carries static or dynamic patterns such as beam splitters, and forms a basic projection image through light transmission. The pattern design combined with lens beam splitting makes the light refract at multiple angles to simulate stereoscopic vision. The combination of double curved lenses can project light in layers, and the superimposed film patterns form a stereoscopic sense of layering. The six-in-one lens 138 integrates six optical functions such as refraction, scattering, and polarization to synthesize multi-angle light. The light path is divided by the multi-faceted lens structure to generate light from different perspectives, realizing the naked-eye 3D effect. Motor 139 drives the six-in-one lens 138 to rotate, dynamically changing the direction of the light path. Combined with the persistence of vision of the human eye, it enhances the stereoscopic dynamic projection effect.

[0027] Specifically, a front cover 12 is provided at one end of the lamp housing 11, and a sealing ring 17 is provided between the lamp housing 11 and the front cover 12.

[0028] In this embodiment, the lamp housing 11 serves as the main support structure, protecting the internal lamp assembly 13 and providing a sealed environment. The front cover 12 is used to fix the lens holder 18, forming a closed space with the lamp housing 11. The sealing ring 17 is provided by tightening the sealing ring 17 after the front cover 12 and the lamp housing 11 are locked together with screws.

[0029] Specifically, an eccentric cover 121 is provided on one side of the front cover 12, and a lens holder 18 is provided inside the eccentric cover 121. The lens holder 18 is coaxially arranged with the first curved lens 132, the film body 134, the second curved lens 137, and the LED beads.

[0030] In this embodiment, the lens holder 18 is designed to be coaxially arranged with the first curved lens 132, the film body 134, the second curved lens 137, and the LED beads, ensuring strict alignment of the light path and avoiding projection distortion. The coaxial design reduces light scattering loss and improves the clarity of the stereoscopic image. The eccentric cover 121 with an off-center design ensures the coaxiality of the lens holder 18 and the lamp assembly 13, while also increasing the appearance of the projection lamp.

[0031] Specifically, a lens body 181 is provided at one end of the lens holder 18, and a sealing ring 19 is provided between one side of the lens body 181 and one side of the inner wall of the eccentric cover 121.

[0032] In this embodiment, the sealing ring 19 ensures the sealing between the eccentric cover 121 and the lens body 181. A waterproof connector is also provided at the end of the lamp housing 11 away from the front cover 12 for threading wires to connect to the lamp board 131. The lamp board 131 is electrically connected to the motor 139.

[0033] Specifically, a connector 14 is fixedly provided at the bottom of the lamp housing 11. One end of the connector 14 is connected to a connecting rod 15 through a locking screw 151 and a nut. The opposite ends of the connecting rod 15 and the connector 14 are provided with meshing toothed discs. A base 16 is provided at the bottom of the connecting rod 15.

[0034] In this embodiment, the 3D projection lamp can be placed on a desktop or other flat surface using the base 16. One end of the locking screw 151 passes through the connecting rod 15 and the connector 14 and is threadedly connected to the nut. Loosening the locking screw 151 allows a small gap to be created between the toothed discs of the connector 14 and the connecting rod 15. The lamp housing 11 can then drive the connector 14 to rotate around the turntable to adjust the angle. After adjustment, the locking screw 151 is tightened again to engage the two toothed discs and fix the angle of the lamp housing 11.

[0035] Example 2, please refer to Figure 1-5 Compared to the above embodiments, this embodiment also includes a ground plug 2, which is sleeved on the bottom of the connecting rod 15. In this embodiment, the ground plug 2 is used to replace the base 16 in the above embodiments, and the 3D projection lamp can be plugged into the ground for use through the ground plug 2.

[0036] In summary, this 3D projection lamp, through the optical combination of the film body 134 and the double-arc lens and the six-in-one lens 138, achieves multi-angle light splitting and dynamic refraction, presenting stereoscopic images without the need for 3D glasses. The coaxial design of the LED beads, the first arc lens 132, the film body 134, the second arc lens 137, and the lens body 181 ensures the alignment accuracy of the light path and eliminates image distortion. The main body can be placed directly on flat areas such as desktops, floors, or windowsills via the base 16 without damaging the surface of the carrier. It is suitable for indoor exhibition halls and cafes where temporary scenes are needed. It can also be used by inserting it into the soil or lawn via the ground plug 2, resisting wind and external shaking, and ensuring long-term stable projection in outdoor courtyards, gardens, and other scenes.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
