As shown in fig. 1 to 6, the present embodiment provides an optical projection lamp, which includes a light source 100, a condenser lens group 200, an image object 300, a perturbation device 400 and a projection lens group 500, which are sequentially disposed along a light path, wherein the light source 100, the condenser lens group 200, the image object 300, the perturbation device 400 and the projection lens group 500 are sequentially disposed along a vertical direction, the perturbation device 400 includes a transparent container 410 and a liquid transparent medium 420 disposed in the transparent container 410, and a volume of the liquid transparent medium 420 is smaller than a volume of the transparent container 410.

In the scheme, the light source 100, the condenser lens group 200, the imaging object 300, the disturbing device 400 and the projection lens group 500 are vertically arranged, mainly because the liquid surface of the liquid-state liquid light-transmitting medium 420 is in a horizontal state under the action of gravity, the vertical arrangement of the structure can enable the light path to be close to the vertical direction, so that the light path can be in a non-parallel state with the horizontal plane, namely the light path can penetrate through the surface of the liquid light-transmitting medium 420, and thus, under the condition that the liquid light-transmitting medium 420 fluctuates, the image distortion effect after the projection imaging of the light path can be reflected; the angle between the light path and the horizontal plane is between 30 and 150 degrees. Specifically, the light path direction is perpendicular to the horizontal plane in this embodiment, and in other embodiments, an included angle between the light path and the horizontal plane may also be 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, or 145 degrees.

The liquid light-transmitting medium 420 in this embodiment may be a colorless transparent liquid medium, or may also be a colored liquid light-transmitting medium 420 having a certain color and having good light-transmitting performance.

The light-transmitting container 410 described in this embodiment is preferably a rigid container having good rigidity, such as a glass container.

As shown in fig. 5 and 6, in the optical projection lamp according to this embodiment, the light-transmitting container 410 is a closed container, and a certain space needs to be reserved in the container when the closed container is adopted, so that the liquid light-transmitting medium 420 forms a surface that can fluctuate, that is, the closed container is not filled with the liquid light-transmitting medium 420, so that the light-transmitting container 410 simultaneously contains the liquid light-transmitting medium 420 and air, an interface between the liquid light-transmitting medium 420 and the air fluctuates along with the movement of the light-transmitting container 410, and in a fluctuating state, when light passes through the liquid interface, the image point position is dynamically changed, so that continuous change of the image shape is generated, and the projection of the imaging object 300 on the image plane exhibits a fluctuating effect.

As shown in fig. 3 and 4, the light-transmitting container 410 used in the optical projection lamp according to the embodiment of the present disclosure is an open container provided with an opening 411, in which case it is necessary to prevent the liquid light-transmitting medium 420 from overflowing from the container during the movement of the light-transmitting container 410, and in this case, the liquid level will always be lower than the lowest position of the opening 411, so that it is possible to ensure that the liquid light-transmitting medium 420 has an upper surface that can form undulations. The opening 411 is disposed at the top of the light-transmissive container 410 in this embodiment.

It should be noted that the number of the openings 411 and the positions of the openings 411 disposed on the light-transmitting container 410 are not limited to the solution described in this embodiment, and in other embodiments, the openings 411 on the light-transmitting container 410 may be two, three, four, or five and the positions of the openings 411 may be two, three, four, or five and all disposed on the top of the light-transmitting container 410, all disposed on the side walls of the light-transmitting container 410, or a portion disposed on the top of the light-transmitting container 410 may be disposed on the side walls of the light-transmitting container 410.

Meanwhile, in the present embodiment, the shape of the light-transmitting container 410 is a rectangular container, the specific shape of the light-transmitting container 410 is not limited to this embodiment, and in other embodiments, the light-transmitting container 410 may also be a circular cylindrical container, a polygonal cylindrical container, a hemispherical container, an oval container, or the like.

Further, the optical projection lamp in this embodiment further includes a vibration device 600 for driving the perturbation device 400 to vibrate, so that the surface of the liquid light-transmitting medium 420 fluctuates.

It should be noted that, in this embodiment, the vibration device 600 is arranged to actively control the vibration of the disturbance generating device, so that the liquid transparent medium 420 forms a disturbed interface in the light path, thereby achieving the purpose of this embodiment and achieving the effect of disturbing the image.

In other embodiments of the present disclosure, the optical projection lamp may be mounted on an elastic element (e.g., a spring), in which case the optical projection lamp fluctuates when a person walks to generate vibration, so that a user experience of artificially generating a disturbance effect may be generated.

In the same principle, in a further preferred embodiment, the elastic element may be disposed inside the optical projection lamp, and the vibration device 600 may be disposed in the elastic element inside the optical projection lamp, and may also be vibrated by human walking vibration or knocking on the housing of the optical projection lamp.

In this embodiment, the vibration device 600 is a knocking device disposed at a side portion of the perturbation device 400. The wall of the light-transmitting container 410 is knocked by controlling the action of the knocking device, so that the liquid light-transmitting medium 420 in the light-transmitting container fluctuates.

In another embodiment of the present disclosure, the vibration device 600 is a moving device for driving the perturbation device 400 to move. In the case that the perturbation device 400 moves, the liquid light-transmitting medium 420 inside the light-transmitting container 410 moves relative to the light-transmitting container 410 due to inertia, so as to achieve the effect of controlling the fluctuation of the liquid light-transmitting medium 420 inside.

In another embodiment of the optical projection lamp according to the present disclosure, the vibration device 600 is a dropping device capable of selectively dropping liquid into the liquid light-transmitting medium 420.

The liquid dropping device may be a circulating dropping device, which is used to extract the liquid transparent medium 420 from the transparent container 410 and drop the liquid transparent medium 420 from the top onto the surface of the transparent liquid in the transparent container 410 to ripple the liquid surface of the liquid transparent medium 420.

It should be noted that the use of a circulating dropping device is not a limitation of the present solution, and in other embodiments, a separate liquid light-transmitting medium 420 may be used as a source of dropping liquid into the light-transmitting container 410. In this case, the circulating drip device may replenish the liquid light-transmitting medium 420 in the light-transmitting container 410, thereby counteracting the loss of the liquid light-transmitting medium 420 from evaporation.

As a preferable technical solution of the optical projection lamp according to the present disclosure, as shown in fig. 6, the optical projection lamp further includes a reflective mirror 700 disposed on a side of the projection lens assembly 500 away from the disturbance device 400, and a mirror surface of the reflective mirror 700 forms an included angle with the optical path for changing a direction of the optical path.

The image plane is usually above without changing the direction of the light path in this scheme, while the projection direction required in actual use may be different according to different scenes of use, and the direction of the light path may be adjusted by providing the reflective mirror 700, so that the projected image plane is not limited to the top.
