[0040] See also Figure 1 and Figure 2 The embodiment of the present application provides a dynamic atmosphere lamp 1000. The dynamic atmosphere lamp 1000 includes a light source assembly 200 and a dynamic projection sheet assembly 100 arranged along the light emitting direction of the light source assembly 200. The dynamic projection sheet assembly 100 includes a dynamic projection sheet 10, a suspension 20 and a sealed cavity 30. Figure 3 The dynamic projection sheet 10 includes a substrate 11 and a pattern structure 12 formed on the substrate 11. The dynamic projection sheet 10 and the suspension 20 are both contained in a sealed cavity 30. When the suspension 20 moves, the dynamic projection sheet 10 is driven to move, so that the pattern of the light emitted by the light source assembly 200 after passing through the pattern structure 12 and emitted from the light outlet changes.

[0041] The dynamic atmosphere lamp 1000 of the embodiment of the present application is provided with a dynamic projection sheet assembly 100 along the light emitting direction of the light source assembly 200. When the suspension 20 moves, the dynamic projection sheet 10 is driven to move, so that the pattern of the light emitted by the light source assembly 200 and emitted from the light outlet changes after passing through the pattern structure 12. In this way, the dynamic change of the atmosphere lamp pattern can be achieved, thereby improving the user experience.

[0042] Among them, the substrate 11 can be made of acrylic (PolyMethyl MetMacrylate, PMMA) material, and the substrate 11 can be in the shape of a disc, or it can be in other shapes according to actual needs, for example, a rectangular sheet, a triangular sheet or an elliptical sheet can be used. The pattern structure 12 on the substrate 11 can be set according to personalized needs, and the pattern structure 12 can include one or more patterns, and the multiple patterns can be the same or different. For example, polygons, circles, stars or various irregular patterns can be selected, and any number and any arrangement can be combined as the pattern structure 12. The pattern structure 12 selected in the embodiment of the present application is a water pattern. The sealed cavity 30 can also be made of PMMA material. The shape of the sealed cavity 30 can be set according to the shape of the substrate 11, or it can be set not according to the shape of the substrate 11. For example, when the substrate is in the shape of a disc, the sealed cavity 30 can be set to a cylindrical shape according to the disc shape of the substrate 11, or it can be set to a rectangular shape not according to the shape of the substrate 11. After the sealed cavity 30 accommodates the dynamic projection sheet 10 and the suspension 20, it is sealed by welding.

[0043] In some embodiments, the dynamic projection sheet 10 comprises a film sheet, which refers to a film used for printing plate making.

[0044] In some embodiments, the movement of the dynamic projection sheet includes suspended swing.

[0045] Specifically, the dynamic projection sheet 10 is suspended in the suspension 20 in the sealed cavity 30. The suspension 20 is suspended and swung, so that the dynamic projection sheet 10 with the pattern structure 12 is suspended and swung. The pattern structure 12 of the dynamic projection sheet 10 produces irregular shielding of the light emitted by the light source assembly 200, and a pattern corresponding to the pattern structure 12 is emitted from the light outlet. For example, when the pattern structure 12 is a water ripple pattern, the pattern emitted from the light outlet will produce a dynamic water ripple disturbance effect. In this way, the dynamic change effect of the atmosphere light pattern is achieved.

[0046] In certain embodiments, suspension 20 includes inorganic mineral oil.

[0047] Among them, inorganic mineral oil has good environmental weather resistance, high stability in most environments, and long service life. Selecting inorganic mineral oil as the suspension 20 can improve the stability and service life of the dynamic atmosphere lamp 1000. The inorganic mineral oil can be selected from low-viscosity transparent inorganic mineral oils, for example, inorganic silicone oil or other colorless transparent inorganic mineral oils. The transparency and viscosity of the inorganic mineral oil can be selected according to actual conditions.

[0048] In one embodiment, the thickness of the dynamic projection sheet 10 can be 0.2 mm; the diameter of the dynamic projection sheet 10 can be 8 mm; the filling thickness of the suspension 20 can be 4 mm; the thickness of the side wall of the sealed cavity 30 (the surface parallel to the light source assembly 200) can be 0.2 mm; and the thickness of the dynamic projection sheet assembly 100 can be 4.6 mm. Of course, in other embodiments, the thickness of the dynamic projection sheet 10, the diameter of the dynamic projection sheet 10, the filling thickness of the suspension 20, the thickness of the side wall of the sealed cavity 30, and the thickness of the dynamic projection sheet assembly 100 can all be set according to actual conditions. It should be pointed out that the plane size of the side wall of the sealed cavity 30 should be larger than the plane size of the dynamic projection sheet 10, so that the dynamic projection sheet 10 can be suspended and swung with the suspension 20.

[0049] The dynamic atmosphere lamp 1000 of the embodiment of the present application utilizes a suspension 20 to immerse a dynamic projection sheet 10 to produce a dynamic pattern disk, thereby eliminating the transmission structure of the pattern disk in the prior art, reducing the manufacturing and assembly of parts, and not requiring energy to drive the pattern disk, thereby reducing energy consumption, thereby ensuring the stability of the dynamic atmosphere lamp 1000, improving the economy of the dynamic atmosphere lamp 1000, and having a more compact structure and high space utilization.

[0050] See also Figure 2 In some embodiments, the light source assembly 200 includes a light source 210 and a circuit board 220 , and the light source 210 is disposed on a side of the circuit board 220 facing the light outlet.

[0051] In one embodiment, the light source 210 can be a Lambertian light source, which is a surface light source with a divergence angle of 120°. The color of the light source 210 can be selected according to individual needs, for example: a light-emitting diode (LED) monochromatic light can be used as the light source 210, or RGB multicolor light can be used as the light source 210. The light source 210 is arranged on the side of the circuit board facing the light outlet, that is, it is arranged toward the dynamic projection sheet assembly 100. The circuit board 220 is a carrier for interconnecting electronic components, and a printed circuit board (PCB) can be used as the circuit board 220. Of course, in other embodiments, the light source 210 may not be a Lambertian light source, and can be selected according to actual conditions. The light source 210 may also use a white LED light source to increase the power of the light source 210, so that the dynamic atmosphere lamp 1000 has a lighting function.

[0052] See also Figure 4 In some embodiments, the dynamic atmosphere lamp 1000 further includes a heat sink 230 , and the heat sink 230 is disposed on a side of the circuit board 220 opposite to the light source 210 .

[0053] Among them, the heat sink 230 is used to dissipate heat to ensure that the light source 210 is in a suitable working environment. The light source 210 has a certain operating temperature range requirement, and too high a temperature may cause the light source 210 to malfunction. Therefore, a heat sink 230 is required to conduct heat and dissipate heat from the light source 210 by using its good thermal conductivity, thereby maintaining the stability of the performance of the light source 210, extending the service life of the light source 210, and further extending the service life of the dynamic atmosphere lamp 1000. In the embodiment of the present application, the heat sink 230 may partially cover or completely cover the circuit board 220. The heat sink 230 may be made of heat dissipation materials such as metal, ceramic, and plastic.

[0054] See also Figure 2 In some embodiments, the dynamic atmosphere lamp 1000 further includes a lighting lens assembly 300 , and the lighting lens assembly 300 is disposed between the light source assembly 200 and the dynamic projection sheet assembly 100 .

[0055] Specifically, since the light source 210 can be a surface light source with a divergence angle, for example, when the light source 210 is a Lambertian light source with a divergence angle of 120°, the illumination lens assembly 300 is arranged between the light source assembly 200 and the dynamic projection sheet assembly 100 to converge and collimate the light emitted from the light source assembly 200, so that it can be irradiated on the dynamic projection sheet 10 after being collimated. On the basis of ensuring the convergence and collimation effects, the illumination lens assembly 300 can be provided with a plurality of illumination lenses, for example: the illumination lens assembly 300 can be provided with 4, 5, 6, ..., N illumination lenses; at the same time, the plurality of illumination lenses in the illumination lens assembly 300 can be positive lenses or negative lenses, the curvatures of the incident surface and the exit surface of each illumination lens can be arbitrarily set, and the plurality of illumination lenses can also be arranged in any order, without limitation here.

[0056] The lighting lens assembly 300 is disposed between the light source assembly 200 and the dynamic projection sheet assembly 100. The lighting lens assembly 300 is spaced apart from the light source assembly 200 and the dynamic projection sheet assembly 100. For example, the distance between the lighting lens assembly 300 and the light source assembly 200 may be 0.5 mm, and the distance between the lighting lens assembly 300 and the dynamic projection sheet assembly 100 may be 1 mm. In addition, the length of the total optical axis of the lighting lens assembly 300 may be 10.8 mm. Of course, in other embodiments, the distance between the lighting lens assembly 300 and the light source assembly 200, the distance between the lighting lens assembly 300 and the dynamic projection sheet assembly 100, and the length of the total optical axis of the lighting lens assembly 300 may be differently set according to actual conditions, and are not limited here.

[0057] See also Figure 2 and Figure 5In some embodiments, the lighting lens assembly 300 includes a first lighting lens 310, a second lighting lens 320, and a third lighting lens 330 arranged in sequence along the optical axis, the first lighting lens 310 is a negative lens, the second lighting lens 320 is a positive lens, and the third lighting lens 330 is a positive lens.

[0058] In one embodiment, the surface of the first lighting lens 310 close to the light source assembly 200 (i.e., the incident surface) is a concave surface, and the surface close to the film assembly 100 (i.e., the exit surface) is a convex surface, and the curvature of the concave surface is greater than the curvature of the convex surface. The surface of the second lighting lens 320 close to the light source assembly 200 (i.e., the incident surface) is a concave surface, and the surface close to the film assembly 100 (i.e., the exit surface) is a convex surface, and the curvature of the concave surface is less than the curvature of the convex surface. The surface of the third lighting lens 330 close to the light source assembly 200 (i.e., the incident surface) is a concave surface, and the surface close to the film assembly 100 (i.e., the exit surface) is a convex surface, and the curvature of the concave surface is less than the curvature of the convex surface.

[0059] It should be noted that the distance between the aforementioned illumination lens assembly 300 and the light source assembly 200 is 0.5 mm, where the distance refers to the distance between the light emitting surface of the light source 210 and the center point of the surface of the first illumination lens 310 close to the light source 210. The distance between the aforementioned illumination lens assembly 300 and the dynamic projection film assembly 100 is 1 mm, where the distance refers to the distance between the center point of the surface of the third illumination lens 330 close to the dynamic projection film assembly 100 and the dynamic projection film 10. The total optical axis length of the aforementioned illumination lens assembly 300 is 10.8 mm, where the total optical axis length refers to the distance between the center point of the surface of the first illumination lens 310 close to the light source 210 and the center point of the surface of the third illumination lens 330 close to the film assembly 100.

[0060] In the implementation manner of the present application, the lighting lens assembly 300 adopts the above-mentioned optical parameter configuration, which can make the lighting lens assembly 300 have better focusing and collimation effects, and the dynamic atmosphere lamp 1000 has better imaging quality.

[0061] See also Figure 2 In some embodiments, the dynamic atmosphere lamp 1000 further includes an objective lens assembly 400, and the objective lens assembly 400 is disposed on a side of the dynamic projection sheet assembly 100 facing the light outlet.

[0062] Specifically, the objective lens assembly 400 is used to magnify the light pattern emitted from the light outlet of the dynamic projection sheet 10. The light pattern emitted from the light outlet is continuously refracted and deflected by the objective lens assembly 400, and is finally projected within a certain distance range to generate an inverted and magnified real image. The real image is the real image projected by the dynamic atmosphere light 1000. At the same time, in this process, the movement of the dynamic projection sheet assembly 100 will disturb the light emitted from the light outlet, and the real image finally projected will change continuously, which can achieve the effect of water ripple disturbance, so as to further enhance the user experience.

[0063] On the basis of ensuring the magnification effect, the objective lens assembly 400 can be provided with a plurality of objective lenses, for example: the objective lens assembly 400 can be provided with 5, 6, 7, ..., N objective lenses; at the same time, the plurality of objective lenses in the objective lens assembly 400 can be positive lenses or negative lenses, the curvature of the incident surface and the exit surface of each objective lens can be set arbitrarily, and the plurality of objective lenses can be arranged in any order, without limitation here. The projection distance range of the dynamic atmosphere lamp 1000 varies according to the different configurations of the objective lens assembly 400 in the actual setting.

[0064] The objective lens assembly 400 is arranged on the side of the dynamic projection sheet assembly 100 facing the light outlet. The objective lens assembly 400 can be spaced apart from the dynamic projection sheet assembly 100. For example, the distance between the objective lens assembly 400 and the dynamic projection sheet assembly 100 can be 0.5 mm. In addition, the length of the total optical axis of the objective lens assembly 400 can be about 10.5 mm, at this time, the exit pupil diameter of the objective lens assembly 400 can be 3 mm. Of course, in other embodiments, the distance between the objective lens assembly 400 and the dynamic projection sheet assembly 100 and the length of the total optical axis of the objective lens assembly 400 can be set differently according to actual conditions, and thus the exit pupil diameter of the objective lens assembly 400 will also be different.

[0065] See also Figure 2 and Figure 6 In some embodiments, the objective lens assembly 400 includes a first objective lens 410, a second objective lens 420, a third objective lens 430, and a fourth objective lens 440 arranged in sequence along the optical axis, the first objective lens 410 is a negative lens, the second objective lens 420 is a positive lens, the third objective lens 430 is a positive lens, and the fourth objective lens 440 is a positive lens.

[0066] In one embodiment, the surface of the first objective lens 410 close to the film assembly 100 is a plane, and the surface opposite to the film assembly 100 is a concave surface. The surface of the second objective lens 420 close to the film assembly 100 is a convex surface, and the surface opposite to the film assembly 100 is a plane. The surface of the third objective lens 430 close to the film assembly 100 and the surface opposite to the film assembly 100 are both convex surfaces, and the curvature of the surface close to the film assembly 100 is greater than the curvature of the surface opposite to the film assembly 100. The surface of the fourth objective lens 440 close to the film assembly 100 is a concave surface, and the surface opposite to the film assembly 100 is a convex surface, and the curvature of the concave surface is less than the curvature of the convex surface.

[0067] It should be noted that the distance between the objective lens assembly 400 and the dynamic projection film assembly 100 is 0.5 mm, where the distance refers to the distance between the center point of the surface of the first objective lens 410 close to the dynamic projection film assembly 100 and the dynamic projection film assembly 100. The total optical axis length of the objective lens assembly 400 is about 10.5 mm, where the total optical axis length refers to the distance between the center point of the surface of the first objective lens 410 close to the film assembly to the center point of the surface of the fourth objective lens 440 opposite to the film assembly 100.

[0068] In the embodiment of the present application, the objective lens assembly 400 adopts the above optical parameter configuration to produce a larger field of view. It is found that after the light emitted from the light outlet of the dynamic projection sheet assembly 100 passes through the objective lens assembly 400, a wide-angle projection with a full field of view of 68° can be achieved. The projection coverage is better than most automotive atmosphere lights on the market, effectively overcoming the limitation of the narrow space in the car and expanding the usability of the whole vehicle.

[0069] In some embodiments, each lens adopts an even-order aspheric surface. That is, the first illumination lens 310, the second illumination lens 320, the third illumination lens 330, the first objective lens 410, the second objective lens 420, the third objective lens 430 and the fourth objective lens 440 may all adopt an even-order aspheric surface.

[0070] Among them, the curvature distribution of the even-order aspheric lens has an even-power symmetrical shape, and the curvature changes with the distance from the optical axis. Each lens uses an even-order aspheric surface, which can effectively reduce aberrations and optimize imaging quality compared to traditional lenses.

[0071] In certain embodiments, at least one lens includes an optically effective area and a non-optical area disposed around the optically effective area, and a light shielding layer is formed on the non-optical area.

[0072] Among them, the optically effective area refers to the area where the lens can optically interact with the light emitted by the light source 210, which is generally the middle area of ​​the lens. The size of the optically effective area may be different in different embodiments. In the implementation mode of the present application, the diameter of the optically effective area may be 3.6 mm. In the implementation mode of the present application, a layer of shading material is applied to the non-optical area to form a shading layer. For example, black paint may be applied to the non-optical area to form a shading layer. Forming a shading layer in the non-optical area can avoid interference from stray light and better optimize imaging quality.

[0073] In some embodiments, at least one of the illumination lens assembly 300 and the objective lens assembly 400 employs a microlens array.

[0074] Among them, the microlens array is an array composed of lenses with a clear aperture and a relief depth of micrometers. It has the basic functions of traditional lenses such as focusing and imaging, and has the advantages of small unit size and high integration. It can complete functions that traditional optical elements cannot complete, and can constitute many new optical systems. At least one of the illumination lens assembly 300 and the objective lens assembly 400 adopts a microlens array. For example, the illumination lens assembly 300 adopts a microlens array, and the objective lens assembly 400 still adopts a plurality of single lenses; or the objective lens assembly 400 adopts a microlens array, and the illumination lens assembly 300 still adopts a plurality of single lenses; or both the illumination lens assembly 300 and the objective lens assembly 400 adopt a microlens array. In this way, the brightness of the real image of the pattern structure 12 finally projected can be made more uniform.

[0075] It should be noted that the various components of the embodiment of the present application can be connected and fixed by means of snap connection, screw connection, etc. All the lenses, dynamic projection sheets 10 and light sources 210 mentioned above are coaxially and colinearly arranged.

[0076] See also Figure 7 The embodiment of the present application provides a vehicle 10000, which includes a vehicle body 2000 and a dynamic atmosphere lamp 1000 of any of the above embodiments, and the dynamic atmosphere lamp 1000 is arranged on the vehicle body 2000. For example, the dynamic atmosphere lamp 1000 can be arranged in the vehicle body 2000, or on the vehicle body 2000, etc.

[0077] The vehicle 10000 of the embodiment of the present application is provided with a dynamic projection sheet assembly 100 along the light emitting direction of the light source assembly 200. When the suspension 20 moves, the dynamic projection sheet 10 is driven to move, so that the pattern of the light emitted by the light source assembly 200 and emitted from the light outlet changes after passing through the pattern structure 12.
