As shown in fig. 1 to 9, the present embodiment provides an optical projection lamp, including a lamp housing 1 having a device installation space, a light source 4, a condenser lens group 5 for converging light emitted from the light source 4 to enhance brightness, an imaging object 6, a disturbance lens 8, and a projection lens 7 are sequentially disposed in the lamp housing 1, the disturbance lens 8 is movably mounted in the lamp housing 1 relative to the imaging object 6 through a disturbance lens driving mechanism, at least one side surface of the disturbance lens 8 is provided with a plurality of arc-shaped convex surfaces 81, and a plurality of adjacent arc-shaped convex surfaces 81 are in continuous smooth transition or non-continuous transition.

Specifically, in the present embodiment, the perturbation lens 8 is a monolithic structure with the arc convex surface 81 on the whole surface.

Under the structure, images presented by the image plane in the whole motion period are dynamic with disturbance effect in the working process of the disturbance lens.

It should be noted that the perturbation lens 8 is not limited to the above-mentioned integral structure with the arc convex surface 81 on all surfaces, and in other embodiments, the perturbation lens 8 may also form a light through hole for the hollow structure 82 on the upper partial region.

By arranging the disturbance lens 8 to have the hollow-out structure 82, light rays are not influenced by the arc convex surface formed on the surface of the disturbance lens when passing through the part, so that the disturbance effect formed by the image surface can be changed, and a traditional still image and a picture alternately showing the disturbance image can be formed.

Specifically, in this scheme, the size of the hollow structure 82 provided in the perturbation lens 8 is greater than or equal to the size of the imaging object.

Or the like, or, alternatively,

the disturbance lens 8 is a plane structure on which a part of area is not provided with an arc convex surface.

By setting the disturbance mirror 8 to be a plane structure in a partial area, an effect similar to the above hollow structure can be obtained.

In the scheme, the disturbance lens 8 is arranged between the imaging object 6 and the projection lens 7, so that the magnification of the projection adjacent position of the imaging object 6 on the image surface is different, the projection imaging of the image surface generates a distortion effect, and meanwhile, the magnification of different positions is dynamically adjusted to change the distortion effect, namely, the projection of the image surface generates dynamic optical distortion, and the projection of the imaging object 6 on the image surface presents a fluctuation effect.

The specific step of dynamically adjusting the magnification at different positions is; the magnification at a certain position is shifted to the magnification at an adjacent position.

The distortion state of the image plane projection can be changed by changing the magnification, the image plane projection is deformed by changing the magnification of each position of the image plane projection in the scheme, and the degree of the image plane projection deformation is changed by dynamically adjusting the magnification of each position.

For example, the partial position on the image surface generates positive distortion, the partial position generates negative distortion, the position generating positive distortion and the position generating negative distortion are alternately arranged, continuous and smooth transition is carried out between the position generating positive distortion and the position generating negative distortion, the magnification of the distortion position is continuously changed, the distortion state of the corresponding position is dynamically changed, the projection effect at the moment presents a dynamic fluctuation effect on the whole image surface, the effect is similar to that of placing pictures at the clear water bottom, and the display effect of the pictures at the water bottom is observed above the water surface in the state of water surface fluctuation.

It should be noted that the area where the positive distortion occurs and the area where the negative distortion occurs are not limited to a continuous smooth transition, but in other embodiments, the distortion state may be adjusted by using a discontinuous transition manner, that is, a scheme that a part of the area where the positive distortion occurs locally generates the negative distortion, and a discontinuous transition between the areas where the positive distortion and the negative distortion occur may be used.

Alternatively, a scheme may be adopted in which only the projection onto the image plane is positively or negatively distorted, and a discontinuous transition is made between regions where positive or negative distortion occurs.

By adopting the scheme, the static pattern can be realized to present a dynamically fluctuating projection effect through an optical scheme, the image plane distortion state is dynamically changed by applying a classic geometric imaging principle and a human eye visual persistence principle, so that the optical distortion size of a local image plane and the similarity of an object image are changed, and the dynamic image effect of regular fluctuation can be presented while the definition of a projection image is kept without loss.

The optical projection lamp as claimed in any one of claims 1 to 7, further comprising a disturbing mirror driving mechanism for driving the disturbing mirror (8) to move, wherein the disturbing mirror driving mechanism comprises a power mechanism (9) and a transmission mechanism, and the transmission mechanism is arranged at a power output end of the power mechanism (9) and is in transmission connection with the power mechanism (9) and the disturbing mirror (8).

9. The optical projection lamp as claimed in claim 8, wherein the disturbing mirror (8) is of a circular structure and is driven by the disturbing mirror driving mechanism to rotate around its axis, or the disturbing mirror (8) is of a rectangular structure and is driven by the disturbing mirror driving mechanism to perform a linear reciprocating motion along the arrangement direction of the arc-shaped convex surfaces (81).

10. An optical projection lamp as claimed in any one of claims 1-7, further comprising a lens fixing plate (21), wherein the lens fixing plate (21) is provided with a light-emitting lens group (22), a lens cover (24) having a light-transmitting hole is provided outside the light-emitting lens group (22), and an arc-shaped lens (23) is provided at the light-transmitting hole.

11. An optical projection lamp as claimed in any one of claims 1 to 7, further comprising a color chip (11), said color chip (11) being arranged between said imaging object (6) and said condenser lens group (5).

12. An optical projection light fixture as claimed in any one of claims 1-7, characterized by further comprising a beam splitting prism (12), said beam splitting prism (12) being arranged on a side of said projection lens (7) remote from said imaging object (6).

13. An optical projection lamp as claimed in any one of claims 1-7, further comprising a pattern wheel (13), wherein said pattern wheel (13) has a circular structure with a plurality of holes for mounting said imaging object (6) on said imaging object (6), and said imaging object (6) corresponding to said condenser lens group (5) can be replaced by rotating said pattern wheel (13).
