For example, lights with water ripple projection effects can be used for interior decoration display, building exterior wall illumination, aquarium projection and garden landscape projection lights.

[0003] At present, there are various types of projection lamps emerging in the market. Among them, the existing projection lamps with flow effects are mostly the combination of LED light source, focusing lens, water wave plate and lens. Among them, the lens is fixed and the water wave plate rotates to form a dynamic pattern projected on the wall. However, the rotation of the water wave plate in front of the LED light source will cause the marginal shadows in the direction of the water ripples projected on the wall, affecting the lighting effect; and the existing lamps with flow projection effect are mostly complex in structure, and the projected light effect has a single fluidity, which has the problem of poor viewing effect. Therefore, it is necessary to improve this. Utility Model Content

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] See also Figure 1 The utility model discloses an optical device with a flow effect, including a first cover body 1, having a first internal space 11; a second cover body 2, located above the first cover body 1; a lamp bead 3, arranged below the first cover body 1; the first cover body 1 and the second cover body 2 both have textures on their surfaces; a driving mechanism 4, the first cover body 1 and the second cover body 2 move relative to each other under the drive of the driving mechanism 4; and a frame, on which the lamp bead 3 and the driving mechanism 4 are fixed.

[0043] Specifically, the frame also includes a fixing plate, and the lamp bead 3 is fixed in the first internal space 11 by the fixing plate.

[0044] When the utility model is used, the positions of the lamp beads 3 and the driving mechanism 4 are fixed by the frame, so that the light emitted by the lamp beads 3 passes through the first cover body 1 and is projected to the outside world through the second cover body 2. Since the first cover body 1 has a first internal space 11, when the light of the lamp beads 3 passes through the first cover body 1, it actually passes through two layers of carriers with textures. Under the action of the textures, the light path of the light passes through the first cover body 1 twice. Twist and / or deform; at the same time, in the process of the driving mechanism 4 driving the first cover body 1 and the second cover body 2 to move relative to each other, since the first cover body 1 and the second cover body 2 are relatively moved, the first cover body 1 and the second cover body 2 are relatively moved. The surface of the second cover body 2 is textured. Therefore, the light emitted by the lamp bead 3 will be distorted and / or deformed in the process of passing through the first cover body 1 and the second cover body 2, and with the relative movement between the two lamp covers, the light path will continue to move and change, so that the light path is distorted and / or deformed after passing through the first cover body 1, and will be distorted and / or deformed again when passing through the second cover body 2. Several light path changes and the superposition and coordination of relative movement can completely break up the light path, and the projected light and shadow have a flowing effect, and the light and shadow flow like water waves, and the light effect is soft and realistic.

[0045] See also Figure 2-5 Further, the first cover body 1 is any one of a cylindrical, columnar, olive-shaped, drum-shaped, cone-shaped, terrace-shaped, and spherical shape. When the first cover body 1 is any one of a cylindrical, columnar, olive-shaped, drum-shaped, cone-shaped, terrace-shaped, and spherical shape, it is ensured to have a stable internal space structure, that is, the first internal space 11, combined with the structure with textures on the surface of the first cover body 1, when the lamp bead 3 is located in the first internal space 11, the light emitted by it will be twisted and / or deformed twice when passing through the first cover body 1 before being projected.

[0046] Example 1

[0047] join Figure 6 , further, it also includes a first lens 5, which is arranged between the lamp bead 3 and the first cover 1. Since the light emitted by the lamp bead 3 is divergent in an obtuse angle range with the lamp bead 3 as the origin, the first lens 5 is located above the lamp bead 3 and can be used for focusing light, so that the light can be gathered by the first lens 5 and then come to the first cover 1, so that the projected light is clearer and has better viewing quality.

[0048] With the lamp bead 3 as the endpoint of the light source, the light emitting angle range is about 100°-140°. Furthermore, the volume of the second lampshade is larger than that of the first lampshade, and the second lampshade is arranged on top of the first lampshade. This structure allows 1) light that has passed through the first cover body 1, and 2) light that has not passed through the first cover body 1 to be projected again from the second lampshade after being twisted and / or deformed. Moreover, the light projected by this structure has a higher sense of layers. In the process of the flow of light and shadow, the light and dark distributions are mixed and combined, and the projection effect is softer and more realistic.

[0049] Driving mode embodiment 1

[0050] See also Figure 1-6 Further, the driving mechanism 4 is connected to the first cover body 1, and is used to drive the first cover body 1 to rotate with the horizontal line 12 where the axis is located as the rotation axis. Specifically, the driving mechanism 4 is a driving motor, and the output end of the driving motor is connected to the first cover body 1 to drive the first cover body 1 to rotate.

[0051] In this structure, since the first cover body 1 has a first internal space 11, when it rotates with the horizontal line 12 where the axis is located as the rotation axis, the light emitted by the lamp bead 3 is emitted through the rotating first lamp cover with a textured surface. The projected light is always in motion and has a flowing light effect. Then, when passing through the second cover body 2, the light emitted by the lamp bead 3 can be completely dispersed, and at the same time, the projected light and shadow have a flowing effect.

[0052] Driving mode embodiment 2

[0053] See also Figure 7 Furthermore, the driving mechanism 4 is connected to the second cover body 2 and is used to drive the second cover body 2 to rotate with the vertical line 21 where the center line of the second cover body 2 is located as the rotation axis.

[0054] Specifically, the driving mechanism 4 at this time includes a driving motor, a gear arranged on the output end of the driving motor, and a rack arranged on the outer periphery of the bottom of the second cover body 2 and meshing with the aforementioned gear; or, the driving mechanism 4 includes a driving motor, a driving wheel arranged on the output end of the driving motor, a driven wheel arranged on the outer periphery of the bottom of the second cover body 2, and a conveyor belt. The driving wheel and the driven wheel are both connected to the conveyor belt. When the motor drives the driving wheel to rotate, the driven wheel can be driven through the conveyor belt, and then the second cover body 2 can be driven to rotate.

[0055] In this structure, the light of the lamp bead 3 is twisted and / or deformed and then projected from the first lampshade, and then emitted through the moving, textured second lampshade. The projected light is always in motion, so that the light emitted by the lamp bead 3 can be completely dispersed, and the projected light and shadow have a flowing effect.

[0056] Driving mode embodiment 3

[0057] See also Figure 8 Furthermore, the driving mechanism 4 includes a first driving structure 41 and a second driving structure 42. The first driving structure 41 is connected to the first cover body 1, and is used to drive the first cover body 1 to rotate around the horizontal line 12 where its axial direction is located as the rotation axis; the second driving structure 42 is connected to the second cover body 2, and is used to drive the second cover body 2 to rotate around the vertical line 21 where its center line is located as the rotation axis.

[0058] Specifically, the first driving structure 41 includes a first driving motor, the output end of the first driving motor is connected to the first cover 1, and drives the first cover 1 to rotate; the second driving structure 42 includes a second driving motor, a gear disposed on the output end of the first driving motor, and a rack disposed on the outer periphery of the bottom of the second cover 2 and meshing with the aforementioned gear; or, the second driving structure 42 includes a second driving motor, a driving wheel disposed on the output end of the second driving motor, a driven wheel disposed on the outer periphery of the bottom of the second cover 2, and a conveyor belt, the driving wheel and the driven wheel are both connected to the conveyor belt, when the second motor drives the driving wheel to rotate, the driven wheel can be driven by the conveyor belt, and then the second cover 2 can be driven to rotate. This structure can ensure that the first cover 1 and the second cover 2 both rotate about their respective rotation axes, and at the same time make the first cover 1 and the second cover 2 move relative to each other, so that the light in the lamp bead 3 is projected in the form of movement after being twisted and / or deformed several times, the light emitted by the lamp bead 3 is scattered, and the projected light and shadow have a flowing effect.

[0059] Example 2

[0060] See also Figure 1-11 , 14-15, further, the second cover body 2 is a curved cover body.

[0061] With the lamp bead 3 as the endpoint of the light source, the luminous angle range is about 100°-140°. Therefore, after the light of the lamp bead 3 is projected through the first cover body 1, it is projected from the second cover body 2 in the shape of a curved surface. Since the surface area of ​​the curved cover body is larger, it can cover more light. Therefore, in this structure, the second cover body 2 can cover more light, so that as much light as possible can be distorted and / or deformed when passing through the second cover body 2 and projected, completely breaking up the light emitted by the lamp bead 3, and the projected light and shadow have a flowing effect.

[0062] Furthermore, an interference sheet 6 is included, and the interference sheet 6 is located between the first cover body 1 and the second cover body 2; or is arranged in the first internal space 11 of the first cover body 1; or is arranged between the lamp bead 3 and the first cover body 1.

[0063] Example 3

[0064] See also Fig. 9 The interference sheet 6 is located between the first cover body 1 and the second cover body 2, so that after the lamp bead 3 emits light, the light is first twisted and / or deformed and projected from the first cover body 1, and then scattered by the interference sheet 6, and then twisted and / or deformed and projected through the second cover body 2. At the same time, under the relative movement of the first cover body 1 and the second cover body 2, the final projected effect is dynamic.

[0065] Example 4

[0066] See also Fig.10The interference sheet 6 is arranged in the first internal space 11 of the first cover body 1, so that after the lamp bead 3 emits light, the light is first twisted and / or deformed and projected from the first cover body 1 for the first time, and then scattered by the interference sheet 6, and then twisted and / or deformed and projected from the first cover body 1 for the second time, and finally twisted and / or deformed and projected from the second cover body 2. At the same time, under the relative movement of the first cover body 1 and the second cover body 2, the projection effect is dynamic.

[0067] Example 5

[0068] See also Fig.11 The interference plate 6 is located between the lamp bead 3 and the first cover body 1, so that the light is dispersed by the interference plate 6, then passes through the first cover body 1, and finally is distorted and / or deformed and projected from the second cover body 2. At the same time, under the relative movement of the first cover body 1 and the second cover body 2, the projected light and shadow have a flowing effect.

[0069] Furthermore, the second cover body 2 is a sheet-shaped cover body, and a focusing lens 7 is provided on the upper side or the lower side of the second cover body 2 .

[0070] Example 6

[0071] See also Fig.12 The focusing lens 7 is arranged on the upper side of the second cover body 2, and the focusing lens 7 is used to focus the light emitted by the lamp beads 3. In this structure, the second cover body 2 is a sheet-shaped cover body, so after the light is emitted from the sheet-shaped cover body, it can be focused in the focusing lens 7 and then dispersed and projected again, so that the light emitted by the lamp beads 3 can be completely dispersed and projected after passing through the layer lampshade and the lens, and the projected light and shadow also have a flowing effect.

[0072] Example 7

[0073] See also Fig.13 , the condenser lens 7 is arranged at the lower side of the second cover body 2. In this structure, the second cover body 2 is a sheet cover body, so after the light is emitted from the first cover body 1, it can be concentrated in the condenser lens 7 and then dispersed and projected again, and then the light is projected from the sheet cover body after being twisted and / or deformed, so that the light emitted by the lamp bead 3 can be completely dispersed and projected after passing through the first lampshade, the condenser lens 7 and the second lampshade in sequence, and the projected light and shadow also have a flowing effect.

[0074] Example 8

[0075] See also Fig.14 When the second cover body 2 is a curved cover body, the focusing lens 7 is arranged on the upper side of the second cover body 2, so that the projected light and shadow can achieve the same effect as the structure of embodiment 6.
