Example two:

as shown in fig. 1 and fig. 11a, an optical system for projecting a three-dimensional shaped laser spot comprises a laser source (1), a scattering element and a continuous refraction element, wherein the scattering element is a scattering lens (2), the scattering lens (2) is an uneven transparent optical lens without a fixed regular shape, and the scattering lens (2) can be any one of the embodiments shown in fig. 12a-12h or the like; continuous refracting element is a disturbance lens (3), disturbance lens (3) are transparent optical lens, and its at least one side is provided with a plurality of cambered surface convex surfaces (33), and is a plurality of be continuous smooth transition or the discontinuous transition between the cambered surface.

It can be understood that the autorotation of the scattering lens or the disturbing lens can be realized by the existing driving mechanism technology of the existing stage lamp.

The laser light source (1) is used for emitting a collimated laser beam, the scattering lens (2) is used for diverging the incident collimated laser beam, and the disturbance lens (3) is used for refracting the incident light; the collimated laser beam emitted by the laser source (1) sequentially passes through the scattering lens (2) and the disturbance lens (3).

Example three:

as shown in fig. 2 and fig. 11b, an optical system for projecting a three-dimensional shaped laser spot comprises a laser source (1), a scattering element and a continuous refraction element, wherein the scattering element is a scattering lens (2), the scattering lens (2) is an uneven transparent optical lens without a fixed regular shape, and the scattering lens (2) can be any one of the embodiments shown in fig. 12a-12h or the like; continuous refracting element is a disturbance lens (3), disturbance lens (3) are transparent optical lens, and its at least one side is provided with a plurality of cambered surface convex surfaces (33), and is a plurality of be continuous smooth transition or the discontinuous transition between the cambered surface.

It can be understood that the autorotation of the scattering lens or the disturbing lens can be realized by the existing driving mechanism technology of the existing stage lamp.

The laser light source (1) is used for emitting a collimated laser beam, the scattering lens (2) is used for diverging the incident collimated laser beam, and the disturbance lens (3) is used for refracting the incident light; collimated laser beams emitted by the laser light source (1) sequentially pass through the scattering lens (2) and the disturbance lens (3); meanwhile, due to the fact that the disturbance lens is provided with the second light through hole (35), after the collimated laser beam emitted by the laser light source (1) penetrates through the scattering lens (2), the collimated laser beam can also be directly emitted from the second light through hole (35) to generate different projection effects.

Example four:

as shown in fig. 3 and fig. 11a, an optical system for projecting a three-dimensional shaped laser spot comprises a laser light source (1), a scattering element and a continuous refraction element, wherein the scattering element comprises a first scattering lens (21) and a second scattering lens (22), the first scattering lens (21) and the second scattering lens (22) are both uneven transparent optical lenses without fixed regular shapes, and the optical lenses can be any one of the embodiments shown in fig. 12a to 12h or the like; continuous refracting element is a disturbance lens (3), disturbance lens (3) are transparent optical lens, and its at least one side is provided with a plurality of cambered surface convex surfaces (33), and is a plurality of be continuous smooth transition or the discontinuous transition between the cambered surface.

The first scattering lens (21) or the second scattering lens (22) can be fixed or can rotate around the center line of the first scattering lens or the second scattering lens by the driving of a driving mechanism; and a second rotary fixing hole (34) is formed in the center of the disturbing lens (3), and the disturbing lens rotates around the central line under the driving of the driving mechanism. It can be understood that the autorotation of the scattering lens or the disturbing lens can be realized by the existing driving mechanism technology of the existing stage lamp.

The laser light source (1) is used for emitting a collimated laser beam, the first scattering lens (21) and the second scattering lens (22) are used for diverging the incident collimated laser beam, and the disturbance lens (3) is used for refracting the incident light; the collimated laser beam emitted by the laser source (1) sequentially passes through the first scattering lens (21), the second scattering lens (22) and the disturbance lens (3).

The two scattering lenses have the advantages that the incident collimated laser beam is diverged twice, and more scattered emergent beams can be generated, so that a three-dimensional fluctuation effect with a fluctuation form different from that of one scattering lens is projected; meanwhile, in the incident direction, the first scattering lens (21) and the second scattering lens (22) may be the same as in any one of the embodiments shown in fig. 12a to 12h or similar, or may be different from each other, such as in any two of the embodiments shown in fig. 12a to 12h or similar; therefore, more abundant three-dimensional special-shaped effects which are obviously different from a single scattering lens can be generated; of course, the weakness of the two diffusion lenses is that the resulting intensity is attenuated due to the addition of a diffusion process.

Example five:

as shown in fig. 4 and fig. 11b, an optical system for projecting a three-dimensional shaped laser spot comprises a laser light source (1), a scattering element and a continuous refraction element, wherein the scattering element comprises a first scattering lens (21) and a second scattering lens (22), the first scattering lens (21) and the second scattering lens (22) are both uneven transparent optical lenses without fixed regular shapes, and the optical lenses can be any one of the embodiments shown in fig. 12a to 12h or the like; continuous refracting element is a disturbance lens (3), disturbance lens (3) are transparent optical lens, and its at least one side is provided with a plurality of cambered surface convex surfaces (33), and is a plurality of be continuous smooth transition or the discontinuous transition between the cambered surface.

The laser light source (1) is used for emitting collimated laser beams, the first scattering lens (21) and the second scattering lens (22) are used for diverging the incident collimated laser beams, and the disturbance lens (3) is used for refracting the incident light.

Besides the beneficial effects of the fourth embodiment, at the same time, due to the second light-passing hole (35) in the disturbing lens, the collimated laser beam emitted by the laser source (1) can directly exit from the second light-passing hole (35) after passing through the first scattering lens (21) and the second scattering lens (22) so as to generate different projection effects.

Example six:

as shown in fig. 5 and fig. 11a, an optical system for projecting a three-dimensional shaped laser spot comprises a laser source (1), a scattering element and a continuous refraction element, wherein the scattering element is a scattering lens (2), the scattering lens (2) is an uneven transparent optical lens without a fixed regular shape, and the scattering lens (2) can be any one of the embodiments shown in fig. 12a-12h or the like; continuous refracting element includes disturbance lens one (31) and disturbance lens two (32), and they are transparent optical lens, and its at least one side is provided with a plurality of cambered surface convex surfaces (33), and is a plurality of be continuous smooth transition or the discontinuous transition between the cambered surface.

It can be understood that the autorotation of the scattering lens or the disturbing lens can be realized by the existing driving mechanism technology of the existing stage lamp.

The laser light source (1) is used for emitting a collimated laser beam, the scattering lens (2) is used for diverging the incident collimated laser beam, and the first perturbation lens (31) or the second perturbation lens (32) is used for refracting the incident light; the collimated laser beam emitted by the laser source (1) sequentially passes through the scattering lens (2), the first disturbance lens (31) and the second disturbance lens (32).

The two disturbing lenses have the advantages that under the action of the two spaced layers of the arc-shaped convex surfaces, imaging is performed twice similarly, a more obvious double continuous fluctuating three-dimensional special-shaped effect can be generated on the projection surface, and certainly, the weakness of the two disturbing lenses is that due to the fact that one imaging lens is added, the final light intensity can be attenuated.

Besides the beneficial effects of the sixth embodiment, simultaneously, because the first disturbing mirror (31) or the second disturbing mirror (32) is provided with the second light passing hole (35), the collimated laser beam emitted by the laser source (1) can directly pass through the second light passing hole (35) of the second disturbing mirror (32) after passing through the scattering mirror (2) or the first disturbing mirror (31), or directly pass through the second light passing hole (35) of the second disturbing mirror (32), or directly emit from the second light passing hole (35), thereby generating different projection effects.
