DETAILED DESCRIPTION Example One

[0023] In combination with the drawings Figure 1 and the drawings Figure 2 A double-pattern double-disturbing effect optical system, comprising a light source 7, a fire disk 4, a rotating pattern disk two 2, a rotating pattern disk one 1, a disturbing lens 3 and an optical lens group 6 for imaging and outgoing light, which are sequentially arranged along the outgoing light path.

[0024] The fire disk 4 is provided with a plurality of flame-shaped hollow holes and a light passing hole. When the light passing hole is located on the main light path 5, the fire disk 4 has no effect on the optical system.

[0025] The rotating pattern disk two 2 is loaded with a plurality of imaging objects two 21 and at least one light passing white circle 22. When the light passing white circle 22 is located on the main light path 5, the rotating pattern disk two 2 has no effect on the optical system. The rotating pattern disk one 1 is loaded with a plurality of imaging objects one 11 and at least one light passing white circle 12. When the light passing white circle 12 is located on the main light path 5, the rotating pattern disk one 1 has no effect on the optical system. The rotating pattern disk two 2 is coaxial with the rotating pattern disk one 1.

[0026] The disturbing lens 3 is provided with a plurality of arc convex surfaces 31 on at least one side. The arc convex surfaces 31 are continuously smooth between adjacent arc convex surfaces 31. The curvature radius of the arc convex surfaces 31 continuously changes between 150-1000mm. The arc surface height of the arc convex surfaces 31 continuously changes between 0.02-2.5mm. The disturbing lens 3 is also provided with a light passing hole. When the light passing hole is located on the main light path, the fire disk 4 has no effect on the optical system.

[0027] The first disturbing effect: when the non-light passing hole area of the disturbing lens 3, i.e. the imaging area, is located on the main light path 5 alone, the disturbing lens 3 can form a realistic water ripple disturbing dynamic spot effect. When used in combination with the imaging objects (11, 21) of the rotating pattern disks (1, 2), the light emitted from the disturbing lens 3 can form a light spot with the pattern on the imaging objects (11, 21), and the light spot will produce a water ripple-like undulating effect. At this time, the light passing hole of the fire disk 4 is located on the main light path 5, which can effectively avoid the influence of the flame-shaped hollow holes on the fire disk 4 on the light spot effect.

[0028] The second disturbance effect: when the flame-shaped hollow hole of the fire plate 4 is located on the main light path 5 alone, the fire plate 4 can form an interlaced illusory flame dynamic light spot effect; and in cooperation with the imaging object of the rotating pattern plate (1, 2), the light emitted from the flame-shaped hollow hole on the fire plate 4 can form a light spot with the pattern on the imaging object (11, 21), and the light spot can produce an illusory flame dynamic effect; at this time, the light transmission hole of the disturbance lens 3 is located on the main light path 5, which can effectively avoid the influence of the imaging area on the disturbance lens 3 on the light spot effect.

[0029] When the non-light transmission hole area, i.e., the imaging area, on the disturbance lens 3 or the flame-shaped hollow hole on the fire plate 4 is alternately cut into the main light path 5 alone, the first or the second disturbance effect can be produced alone.

[0030] The working principle of switching between the first disturbance effect and the second disturbance effect:

[0031] The two different disturbance effects can be switched with each other, as known from the above, the switching between the two different disturbance effects is that the imaging area of the disturbance lens 3 or the fire plate 4 is alternately cut into the main light path 5, that is, the imaging area of the disturbance lens 3 and the fire plate 4 cannot be located on the main light path 5 at the same time; when the imaging area of the disturbance lens 3 is located on the main light path 5, the imaging area of the fire plate 4 cannot be located on the main light path 5; similarly, when the imaging area of the fire plate 4 is located on the main light path 5, the imaging area of the disturbance lens 3 cannot be located on the main light path 5. It can be understood that the disturbance lens 3 and the fire plate 4 are alternately cut into the main light path 5, which is not in a certain order and the cutting time is equal; for example, when the disturbance lens 3 rotates on the main light path 5, the imaging area of the disturbance lens 3 is cut into the main light path 5, and then the light transmission hole of the disturbance lens 3 is cut into the main light path 5 as the imaging area of the disturbance lens 3 is cut out of the main light path 5; after the light transmission hole of the disturbance lens 3 is cut into the main light path 5, the imaging area of the disturbance lens 3 can continue to cut into the main light path 5 repeatedly, or the imaging area of the fire plate 4, i.e., the flame-shaped hollow hole, can be cut into the main light path 5 immediately; and the time of the disturbance lens 3 or the fire plate 4 in the working state each time cut into the main light path 5 can be equal or unequal.

[0032] Compared with the patent CN110347006A, the utility model has two beneficial effects:

[0033] The first beneficial effect: the optical system is increased with different disturbance effects, and the light spot patterns formed by the optical system are enriched; by adding the rotating pattern plate two 2, the light spot patterns are increased in various shapes; by adding the fire plate 4, another disturbance effect is increased, so that the utility model is an optical system with the above two disturbance effects.

[0034] Second beneficial effect: improve the strict limit of the distance between the perturbation lens 3 and the imaging object, the patent CN110347006A mentions that "the curvature radius of the arc convex surface is continuously changed between 6-150mm"; because the curvature of the arc convex surface is small, the patent CN110347006A has strict restrictions on the distance between the perturbation lens 3 and the imaging object. The curvature of the arc convex surface 31 of the perturbation lens 3 is increased in the utility model, and the curvature radius of the arc convex surface 31 is continuously changed between 150-1000mm, so that the distance between the perturbation lens 3 and the imaging object is no longer strictly limited; Even if the distance between the perturbation lens 3 and the imaging object is large, a relatively clear light spot can also be formed; and the increase in the height of the arc surface of the arc convex surface 31 of the utility model can increase the amplitude of the perturbation effect of the formed light spot pattern.

[0035] As a new embodiment, the utility model is combined with the accompanying drawings Figure 1 The distance d1 between the imaging object one 11 and the perturbation lens 3 is 6mm≤d1≤15mm. When d1<6mm, the distance between the perturbation lens 3 and the imaging object one 11 is too close, and the dynamic effect of the light spot formed by the light rays passing through the perturbation lens 3 and the imaging object one 11 is relatively slight, that is, the perturbation effect is weak; when d1>15mm, the distance between the perturbation lens 3 and the imaging object one 11 is too far, and the clarity of the dynamic light spot formed by the light rays passing through the perturbation lens 3 and the imaging object one 11 is reduced. The beneficial effect of this embodiment is that the light rays of the perturbation lens 3 and the imaging object one 11 can also form a clear light spot with a clear dynamic change amplitude.

[0036] As a new embodiment, the utility model is combined with the accompanying drawings Figure 1 The distance d2 between the imaging object two 21 and the fire plate 4 is 2mm≤d2≤20mm. When d1<2mm, the distance between the fire plate 4 and the imaging object two 21 is too small, and the fire plate 4 can be clearly imaged like the imaging object two 21, so that the blurring effect of the dynamic flame light spot formed by the light rays passing through the fire plate 4 and the imaging object two 21 is not good; when d1>20mm, the distance between the fire plate 4 and the imaging object two 21 is too large, which increases the overall volume of the optical system. The beneficial effect of this embodiment is that the light spot formed by the light rays passing through the fire plate 4 can achieve a better blurring effect, and is not prone to interference, and is conducive to making the optical system more compact.

[0037] In terms of the position distribution of the imaging object one 11 and the imaging object two 21:

[0038] The utility model is combined with the accompanying drawings Figure 1, the imaging object one 11 is arranged on the rotating pattern disc one 1 close to one side of the disturbance lens 3, and the imaging object two 21 is arranged on the rotating pattern disc two 2 away from one side of the fire disc 4. The rotating pattern disc one 1 and the rotating pattern disc two 2 are arranged in the same direction and are installed along the light emitting direction; the upper surface of the rotating pattern disc one 1 is close to one end of the disturbance lens 3, and the lower surface of the rotating pattern disc one 1 is away from one end of the disturbance lens 3; the upper surface of the rotating pattern disc two 2 is away from one end of the fire disc 4, and the lower surface of the rotating pattern disc two 2 is close to one end of the fire disc 4; the imaging object one 11 is installed on the upper surface of the rotating pattern disc one 1, and the imaging object two 21 is installed on the upper surface of the rotating pattern disc two 2; the combined height of the rotating pattern disc one 1 and the rotating pattern disc two 2 in the light emitting direction is fixed, and the imaging object can be installed on the upper surface or the lower surface of the rotating pattern disc one 1 and the rotating pattern disc two 2. The beneficial effect of this embodiment is that the position of the imaging object can be changed without changing the combined height of the rotating pattern disc one 1 and the rotating pattern disc two 2 in the light emitting direction.

[0039] In the aspect of the disturbance lens 3 and the imaging object one 11 cooperating to image:

[0040] In combination with the accompanying drawings Figure 1 The disturbance lens 3 and the imaging object one 11 are used for imaging. The material of the disturbance lens 3 is glass, and the imaging object one 11 is a glass pattern piece; as can be understood by those skilled in the art, there is a light shielding area on the imaging object one 11, and the light spot formed by the light emitted from the imaging object one 11 is the projection of the light shielding area; when the light emitted from the imaging object one 11 passes through the disturbance lens 3 again, the light emitted from the disturbance lens 3 scatters and refracts in all directions due to the arc surface of the arc convex surface 31 arranged on the disturbance lens 3; therefore, the light spot formed by the light passing through the disturbance lens 3 can present a dynamic effect of forming water ripples fluctuating; for example, when the light shielding area on the imaging object one 11 is in the shape of seaweed and is used in combination with the disturbance lens 3, a dynamic pattern light spot similar to the shape of seaweed swaying gently with water waves will be formed; at this time, the distance between the imaging object one 11 and the disturbance lens 3 is the closest, so the formed light spot is the clearest, but the disturbance effect is weaker. The beneficial effect of this embodiment is that it is beneficial to form a clear and dynamic fluctuation obvious light spot effect.

[0041] In the aspect of the fire disc 4 and the imaging object two 21 cooperating to image:

[0042] In combination with the accompanying drawings Figure 1, the fire plate 4 and the imaging object two 21 are used for imaging. The fire plate 4 is a metal pattern plate provided with a plurality of flame-shaped hollow holes and a light transmission hole, and the imaging object two 21 is a metal pattern sheet provided with a hollow pattern. As can be understood by those skilled in the art, for example, when the hollow pattern of the imaging object two 21 is a square, the flame-shaped light spot formed after the light passes through the imaging area of the fire plate 4 and the imaging object two 21 is a square flame-shaped light spot, that is, the shape of the hollow pattern of the imaging object two 21 determines the outer contour shape of the light spot. When the fire plate 4 rotates, the flame in the light spot changes with the rotation of the fire plate 4, forming a dynamic flame-shaped light spot with a disturbance effect. At this time, the imaging object two 21 is farthest from the fire plate 4, so the blurring effect of the flame of the formed light spot is the best. The beneficial effect of this embodiment is that it is beneficial to form a dynamic flame-shaped light spot with good blurring effect and obvious disturbance effect.

[0043] As a new embodiment, the distance d3 between the imaging object one 11 and the imaging object two 21 is 2mm≤d3≤6mm in combination with the drawings. When d3<2mm, the distance between the two rotating pattern plates (1, 2) is too close, which is easy to interfere; that is, the rotating pattern plate one 1 and the rotating pattern plate two 2 are easy to collide when rotating; when d3>6mm, because the distance between the two coaxial imaging objects (11, 21) is far, the distance between the two rotating pattern plates (1, 2) is also large, and the height of the optical system in the light output direction also increases. The beneficial effect of this embodiment is that it is beneficial to make the distribution of the optical system in the light output direction more compact, saving space.

[0044] As a new embodiment, the distance d3 between the imaging object one 11 and the imaging object two 21 is 2mm≤d3≤6mm in combination with the drawings. When d3<2mm, the distance between the two rotating pattern plates (1, 2) is too close, which is easy to interfere; that is, the rotating pattern plate one 1 and the rotating pattern plate two 2 are easy to collide when rotating; when d3>6mm, because the distance between the two coaxial imaging objects (11, 21) is far, the distance between the two rotating pattern plates (1, 2) is also large, and the height of the optical system in the light output direction also increases. The beneficial effect of this embodiment is that it is beneficial to make the distribution of the optical system in the light output direction more compact, saving space. Figure 1 , the driving device is used to drive the rotating pattern plate one 1 or the rotating pattern plate two 2 or the fire plate 4 or the disturbance mirror 3 to rotate. The disturbance mirror 3, the fire plate 4, the rotating pattern plate one 1 and the rotating pattern plate two 2 are all installed on the same center axis, and the driving device can respectively cut the disturbance mirror 3, the fire plate 4, the rotating pattern plate one 1 and the rotating pattern plate two 2 into or out of the main light path 5, or simultaneously cut the disturbance mirror 3 and the rotating pattern plate one 1 or the fire plate 4 and the rotating pattern plate two 2 into the main light path 5; or make the disturbance mirror 3 or the fire plate 4 rotate on the main light path 5. The beneficial effect of this embodiment is that the disturbance mirror 3 or the fire plate 4 can rotate on the main light path 5, and different imaging objects (11, 21) can be switched.

[0045] As a new embodiment, the distance d3 between the imaging object one 11 and the imaging object two 21 is 2mm≤d3≤6mm in combination with the drawings. When d3<2mm, the distance between the two rotating pattern plates (1, 2) is too close, which is easy to interfere; that is, the rotating pattern plate one 1 and the rotating pattern plate two 2 are easy to collide when rotating; when d3>6mm, because the distance between the two coaxial imaging objects (11, 21) is far, the distance between the two rotating pattern plates (1, 2) is also large, and the height of the optical system in the light output direction also increases. The beneficial effect of this embodiment is that it is beneficial to make the distribution of the optical system in the light output direction more compact, saving space. Figure 1The optical lens group 6 comprises a focusing lens group 61, a magnifying lens group 62 and a light-emitting lens group 63. The focusing lens group 61 can adjust the focal length and determine the imaging position of the outgoing light rays; the magnifying lens group 62 can magnify the light spot formed by the outgoing light rays; and the light-emitting lens group 63 focuses the outgoing light rays on the imaging plane to form a clear light spot. The beneficial effect of this embodiment is that it can form an imaging position-adjustable, size-changeable and clear light spot. Embodiment Two

[0046] The difference between Embodiment Two and Embodiment One lies in the different position distribution of the imaging object two 21 and the different imaging effects of the combination of the fire plate 4 and the imaging object two 21.

[0047] In terms of the position distribution of the imaging object two 21:

[0048] In combination with the accompanying drawings Figure 3 The imaging object one 11 is arranged on the rotating pattern plate one 1 close to one side of the disturbance lens 3, and the imaging object two 21 is arranged on the rotating pattern plate two 2 close to one side of the fire plate 4. The rotating pattern plate one 1 and the rotating pattern plate two 2 are arranged in the same direction, the imaging object one 11 is installed on the upper surface of the rotating pattern plate one 1, and the imaging object two 21 is installed on the lower surface of the rotating pattern plate two 2; the combined height of the rotating pattern plate one 1 and the rotating pattern plate two 2 in the light-emitting direction is unchanged, but the position of the imaging object two 21 is changed; at this time, the distance between the imaging object one 11 and the imaging object two 21 is the farthest. The beneficial effect of this embodiment is that the position of the imaging object two 21 can be changed without changing the combined height of the rotating pattern plate one 1 and the rotating pattern plate two 2 in the light-emitting direction.

[0049] In terms of the combination imaging of the disturbance lens 3 and the imaging object one 11:

[0050] The combination imaging of the disturbance lens 3 and the imaging object one 11 is the same as that of Embodiment One.

[0051] In combination with the accompanying drawings Figure 3 The disturbance lens 3 is combined with the imaging object one 11 for imaging. In this embodiment, the distance between the imaging object one 11 and the disturbance lens 3 is the closest, so the formed light spot is the clearest, but the disturbance effect is weaker. The beneficial effect of this embodiment is that it is conducive to forming a clear and dynamic light spot effect.

[0052] In terms of the combination imaging of the fire plate 4 and the imaging object two 21:

[0053] The difference between this embodiment and Embodiment One lies in the different distance between the fire plate 4 and the imaging object two 21.

[0054] In combination with the accompanying drawings Figure 3, the fire plate 4 and the imaging object two 21 are used for imaging. In this embodiment, the imaging object two 21 is closest to the fire plate 4, and although a better defocusing effect and obvious disturbance effect can be formed, compared with the light spot in the first embodiment, there are still some changes; for example, the edge of the flame in the light spot is the most clear, and the disturbance effect is relatively weakened compared with the first embodiment. The beneficial effect of this embodiment is that it is beneficial to form a dynamic flame light spot with a better defocusing effect and obvious disturbance effect. Example three

[0055] The difference between the third embodiment and the first embodiment is that the orientation of the rotating pattern disc one 1 is different, the imaging effect of the disturbance mirror 3 and the imaging object one 11 is different, and the imaging object one 11 and the imaging object two 21 can be combined and arranged on the main light path 5.

[0056] In terms of the orientation of the rotating pattern disc one 1:

[0057] As a new embodiment, the accompanying drawings are combined Figure 4 The imaging object one 11 is arranged on the rotating pattern disc one 1 away from the disturbance mirror 3, and the imaging object two 21 is arranged on the rotating pattern disc two 2 away from the fire plate 4. The rotating pattern disc one 1 and the rotating pattern disc two 2 are arranged opposite to each other, that is, the rotating pattern disc one 1 is installed in the direction of the light source 7; in this embodiment, the lower surface of the rotating pattern disc one 1 is located at one end close to the disturbance mirror 3, and the upper surface of the rotating pattern disc one 1 is located at one end away from the disturbance mirror 3; the imaging object one 11 is still located on the upper surface of the rotating pattern disc one 1, but due to the change in the installation direction of the rotating pattern disc one 1, the position of the imaging object one 11 is also changed; at this time, the distance between the imaging object one 11 and the imaging object two 21 is the closest. The beneficial effect of this embodiment is that the position of the imaging object one 11 can be changed without changing the combined height of the rotating pattern disc one 1 and the rotating pattern disc two 2 in the light emitting direction.

[0058] In terms of the imaging of the disturbance mirror 3 and the imaging object one 11:

[0059] The difference from the first embodiment is that the distance between the disturbance mirror 3 and the imaging object one 11 is different.

[0060] The accompanying drawings are combined Figure 4 The disturbance mirror 3 and the imaging object one 11 are used for imaging. In this embodiment, the distance between the imaging object one 11 and the disturbance mirror 3 is the farthest, and although a relatively clear and dynamic fluctuation obvious light spot can be formed, compared with the first embodiment, there are still some changes; for example, the disturbance effect of the light spot is relatively enhanced compared with the first embodiment, but the clarity of the light spot is relatively reduced compared with the first embodiment. The beneficial effect of this embodiment is that it is beneficial to form a light spot effect that is relatively clear and has the most obvious dynamic fluctuation.

[0061] In the aspect of imaging by the combination of the fire plate 4 and the imaging object two 21:

[0062] The same as the imaging by the combination of the fire plate 4 and the imaging object two 21 in the first embodiment.

[0063] In combination with the drawings Figure 4 The fire plate 4 and the imaging object two 21 are combined for imaging. In the present embodiment, the imaging object two 21 is farthest from the fire plate 4, and thus the best blurring effect of the flame of the formed light spot. The beneficial effect of the present embodiment is that it is conducive to forming a dynamic flame light spot with good blurring effect and obvious disturbance effect.

[0064] In the aspect of imaging by the combination of the imaging object one 11 and the imaging object two 21:

[0065] In combination with the drawings Figure 4 The disturbance mirror 3 or the fire plate 4 is combined with the combination of the imaging object one 11 and the imaging object two 21 for imaging. As can be understood by those skilled in the art, since the imaging object one 11 and the imaging object two 21 are closest, the imaging object one 11 and the imaging object two 21 are within the range that can be clearly imaged, thus the imaging object one 11 and the imaging object two 21 can be imaged, and a relatively clear image can be formed; when the disturbance mirror 3 is combined with the combination of the imaging object one 11 and the imaging object two 21 for imaging, a dynamic light spot with obvious disturbance effect and relatively clear image can be formed; when the fire plate 4 is combined with the combination of the imaging object one 11 and the imaging object two 21 for imaging, a dynamic flame light spot with good blurring effect and obvious disturbance effect can be formed. The beneficial effect of the present embodiment is that both a dynamic light spot with obvious disturbance effect and relatively clear image and a dynamic flame light spot with good blurring effect and obvious disturbance effect can be formed; the disturbance mirror 3 or the fire plate 4 can be cut into the main light path 5 according to different needs.
