[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] The following is in conjunction with the appendix Figures 1 to 7 To further describe, this utility model discloses an ultra-high-definition variable focal length AI lamp, including a lamp housing 1, a light module 3, a face cover 4, a lamp bracket 2, and a lens assembly 5. The lamp bracket 2 is fixedly connected to the lamp housing 1 by screws. The storage space formed inside the lamp housing 1 is used to install the light module 3, and the storage space is sealed by the face cover 4. The lens assembly 5 is installed on the face cover 4 and is positioned opposite to the light module 3 inside the lamp housing 1. The light spot or pattern emitted by the light module 3 is projected onto the irradiated surface through the lens assembly 5, and the clarity of the light spot or pattern is adjusted by adjusting the focal length of the lens assembly 5.

[0031] The illumination module 3 includes a substrate 31 and a dot matrix pixel light source 30. The substrate 31 is circular, polygonal, or irregular in shape, while the dot matrix pixel light source 30 uses Micro LEDs. The white light chip or RGB chip array of the Micro LED is distributed on the substrate 31 and can output dynamic and static digital information such as text characters, graphics, and images in white light, monochromatic light, or full-color light. The illumination module 3 is connected to a control circuit board 6, which is located inside the lamp housing 1. Each light-emitting point of the Micro LED can be individually controlled through the control circuit board 6. In addition to controlling the on / off state of each pixel, the control circuit board 6 can also control the brightness of each pixel. Then, through the changes in the on / off state and brightness of the light source pixels, various different light spot shapes or patterns can be generated in real time. Then, the projected light is focused and diverged by the lens assembly 5 to achieve ultra-high definition of the light spot shape or pattern. It can be projected onto roads or other application scenarios according to actual needs.

[0032] The lens assembly 5 is located in the light output direction of the illumination module 3. The lens assembly 5 includes a lens cover 50, a first lens 51 and a second lens 52. The number of the first lens 51 and the second lens 52 can be increased according to actual needs. In this embodiment, the first lens 51 and the second lens 52 are one or a combination of two of the following: a meniscus lens, a single-sided convex lens, and a double-sided convex lens.

[0033] The lens cover 50 is connected to the external thread of the lamp tube 41 on the face cover 4 via the connecting thread provided on the inner wall. The second lens 52 is disposed inside the lens cover 50 and is positioned opposite to the first lens 51. The distance between the second lens 52 and the first lens 51 can be adjusted by rotating the lens cover 50 clockwise or counterclockwise, thereby adjusting the focal length of the second lens 52.

[0034] Furthermore, the first lens 51 is disposed inside the lamp tube 41 on the faceplate 4. The external thread of the first lens 51 is adapted to the internal thread of the inner wall of the lamp tube 41 through the external thread provided on its outer side. The distance between the first lens 51 and the illumination module 3 is adjustable. Specifically, by rotating the first lens 51 clockwise or counterclockwise, the distance between the first lens 51 and the illumination module 3 can be adjusted, thereby adjusting the focal length of the first lens 51. In this embodiment, the focal lengths of both the first lens 51 and the second lens 52 can be adjusted independently.

[0035] In a preferred embodiment, a reinforcing rib 10 is provided on the back of the lamp housing 1 to strengthen the lamp body structure and assist in heat dissipation. Mounting screw holes are provided on both sides of the lamp housing 1, and the two ends of the lamp bracket 2 are respectively matched with the mounting screw holes on both sides of the lamp housing 1 by fixing screws 7.

[0036] In a preferred embodiment, the face cover 4 is provided with a concave area 40 and a lamp tube 41. The lamp tube 41 extends outward from the concave area 40 to form a cylindrical body, so that the distance between the first lens 51 and the illumination modules 3, and between the first lens 51 and the second lens 52, has an adjustable stroke. The inner and outer walls of the lamp tube 41 are respectively provided with internal threads and external threads. The first lens 51 is rotatably disposed inside the lamp tube 41 by thread engagement with the internal thread of the lamp tube 41. The external thread of the lamp tube 41 is connected to the internal thread of the lens cover 50.

[0037] In a preferred embodiment, the surface of the cover 4 is further provided with raised textures 42, which are distributed outward from the center of the lamp tube 41.

[0038] In a preferred embodiment, the inner wall of the lens cover 50 is provided with connecting threads to connect with the outer thread of the lamp tube 41, the outer wall of the lens cover 50 is provided with concave and convex textures 53, the second lens 52 is disposed inside the lens cover 50, and the lamp head cover is cylindrical.

[0039] In a preferred embodiment, the adjustable distance between the first lens 51 and the illumination module 3 is 0-100mm.

[0040] In a preferred embodiment, the adjustable distance between the first lens 51 and the second lens 52 is 0-100mm.

[0041] Table 1 provides, for example, the zoom parameters for the first and second lens structures:

[0042] zoom range Lens material Aperture number F# wavelength Magnification distortion 2-8mm PMMA 3.05 Visible light 55-105 times 0.00756%

[0043] Combined with appendix Figures 4 to 9 As can be seen, taking the size and distance parameters of the first and second lenses mentioned above as examples, the test parameters are based on three configurations with object distances of 2000mm, 5000mm, and 8000mm. Each configuration corresponds to an optical system with different focal lengths and positions, resulting in a standard dot matrix diagram. This diagram shows the change in image sharpness as the focal length changes, based on the parameters mentioned above. This confirms that the present application demonstrates excellent imaging performance through a dot matrix pixel light source combined with a multi-lens focusing design.

[0044] In summary, rotating the first lens allows adjustment of the distance between it and the light source module, enabling focusing between them. Rotating the lens hood and the faceplate adjusts the distance between the second lens and the first lens, allowing the second lens to focus on light and shadow. Furthermore, the illumination module uses a dot-matrix pixel light source. By editing the pixel light source through the control circuit board, various light spot shapes or patterns can be generated in real time using the brightness and darkness changes of the light source pixels. Then, through optical processing such as focusing and divergence of the first and second lenses, the clarity of the light spot shape or pattern is adjusted and optimized in real time to present a clear, high-quality image. Compared with existing technologies, this design is more adaptable to multiple application scenarios.

[0045] Although embodiments of the present invention have been shown above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications and variations to the above embodiments, but such modifications are all included within the broad scope of the foregoing disclosure, drawings and claims.
