[0092] To make the objectives, technical solutions and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0093] In the present application, the terms "outer" and "inner" refer to directions relative to an observer. "Outer" refers to the direction facing the observer, and "inner" refers to the direction away from the observer.

[0094] Figure 1 Schematically shows a vehicle 1 according to an embodiment of the application. As Figure 1 and Figure 2 shown, the vehicle 1 includes multiple interior trim parts, such as a dashboard 10, a ceiling 11, and a door panel 12. An optical trim part 2 for the vehicle (simply referred to as the optical trim part 2 hereinafter for simplicity) is provided on any one of these interior trim parts to make the interior trim part display a specific lighting effect as needed.

[0095] The optical trim part 2 will be described hereinafter.

[0096] As Figure 3 shown, the optical trim part 2 includes a reflective film layer 3 and a light-emitting film layer 4. The reflective film layer 3 is light-transmissive and is provided with a light-transmissive texture structure 312 (as Figure 6 shown). The texture structure 312 can reflect the first light ray 201 from the ambient light source 203 away from the optical trim part 2. The light-emitting film layer 4 has a light-emitting surface 412 facing the reflective film layer 3. The reflective film layer 3 covers the light-emitting surface 412 of the light-emitting film layer 4 (in other words, the light-emitting film layer 4 is inside the reflective film layer 3). The light-emitting film layer 4 is also provided with a preset pattern 411 formed by a plurality of optical microstructures 410 (as Figure 18 and Figure 21 shown). The second light ray 202 propagating in the light-emitting film layer 4 will change its propagation direction after passing through these optical microstructures 410 and then emit from the light-emitting surface 412 and pass through the reflective film layer 3 to emit from the optical trim part 2. In one embodiment, the preset pattern 411 and the texture structure 312 at least partially overlap.

[0097] When using the optical trim part 2 of the present application, when there is only the first light ray 201 from the ambient light source 203 outside the optical trim part 2, the first light ray 201 irradiates on the texture structure 312 of the reflective film layer 3, and the texture structure 312 reflects the first light ray 201 away from the optical trim part 2, so that the observer 206 can see the first display effect produced by the reflective film layer 3 presented by the optical trim part 2 (such as Figure 4a the texture 205 or other patterns shown). When there is the first light ray 201 and there is also the second light ray 202 in the light-emitting film layer 4 (as Figure 3 shown), the user 206 can see the superposition of the first display effect and the second display effect produced by the light-emitting film layer 4 presented by the optical trim part 2 (such as Figure 4bThe texture 205 and the preset pattern 411 shown). When there is no first light and only the second light exists, the user can see that the optical ornament 2 only presents the second display effect generated by the light-emitting film layer 4, which realizes the effect of hiding the texture or other patterns on the reflective film layer 3. Thus, when using the optical ornament 2 of the present application, the optical ornament 2 can have a variety of different display effects to meet the diverse needs of users.

[0098] In one embodiment, the ambient light source 203 can be an interior light, the sun, a street lamp in the vehicle external environment, or other light sources on the outer side of the optical ornament 2 (i.e., the side of the optical ornament 2 close to the observer 206).

[0099] In one embodiment, the interior light can be a single or multiple LED lamp beads. The lighting state and / or color and / or light intensity and / or lighting time of the interior light can all be controlled according to the actual situation to make the first display effect of the optical ornament 2 more rich and variable. For example, multiple LED lamp beads can be lit simultaneously or lit or extinguished according to an appropriate timing sequence to make the optical ornament 2 present a static or dynamic first display effect, such as display effects like flowing water, flashing, breathing, and depth perception.

[0100] Also as Figure 3 shown, the optical ornament 2 further includes a skeleton layer 5. The light-emitting film layer 4 is mounted on the skeleton layer 5. In this way, the optical ornament 2 forms an independent module, which is convenient for storage, transportation, and also convenient for disassembly and assembly on the interior trim of the vehicle 1.

[0101] At least part of the skeleton layer 5 is made of a heat-conducting material. This helps to improve the heat dissipation effect of the optical ornament 2. This is particularly advantageous when the optical ornament 2 uses a high-power interior light and / or a high-power light source 204 (described below). In one embodiment, the heat-conducting material can be a metal such as aluminum, magnesium, copper, or a heat-conducting plastic.

[0102] In one embodiment, the thickness of the reflective film layer 3 can be at least 0.7 mm at a minimum, the thickness of the light-emitting film layer 4 is less than or equal to 1 mm, the thickness of the skeleton layer 5 made of metal can be at least 0.4 mm at a minimum, and the thickness of the skeleton layer 5 made of heat-conducting plastic can be at least 2.5 mm at a minimum. In this way, the total thickness of the optical ornament 2 is relatively small, which is convenient for use in a narrow space; and it will not significantly increase the thickness of the interior trim of the vehicle 1, thereby avoiding significantly reducing the occupant space in the vehicle 1.

[0103] In one embodiment, the reflective film layer 3 and the light-emitting film layer 4 are directly mounted on the interior trim of the vehicle 1 as a whole. In this way, the optical ornament 2 has no skeleton layer, which helps to further reduce the thickness of the optical ornament 2.

[0104] Next, the reflective film layer 3 will be described.

[0105] As Figure 5 shown, the reflective film layer 3 includes a texture layer 31, a carrier layer 32, and a first modification layer 33. The texture layer 31 is provided with the texture structure 312 described above. The carrier layer 32 is located between the texture layer 31 and the first modification layer 33. Among them, the texture layer 31 is installed on the outer surface of the carrier layer 32, and the first modification layer 33 is installed on the inner surface of the carrier layer 32. In other embodiments, the texture layer 31 can also be located between the carrier layer 32 and the first modification layer 33. Among them, the carrier layer 32 is installed on the outer surface of the texture layer 31, and the first modification layer 33 is installed on the inner surface of the texture layer 31. In addition, the first modification layer 33 can also be located between the texture layer 31 and the carrier layer 32. For simplicity, the technical solution of this application is described by taking the carrier layer 32 being located between the texture layer 31 and the first modification layer 33 as an example.

[0106] The carrier layer 32 is used to carry the texture layer 31. For example, the carrier layer 32 includes a light-transmitting area 321 and a mounting area 322. The texture structure 312 on the texture layer 31 corresponds to the light-transmitting area 321 in a direction perpendicular to the light-transmitting area 321, and the orthographic projection of the preset pattern 411 of the light-emitting film layer 4 facing the light-transmitting area 321 is within the range of the light-transmitting area 321. In this way, in the presence of the first light ray 201 and / or the second light ray 202, the optical ornament 2 can present the first display effect and / or the second display effect.

[0107] The mounting area 322 deviates from the light-transmitting area 321 and is used to connect with the light-emitting film layer 4. For example, the mounting area 322 surrounds the light-transmitting area 321. In one embodiment, screws or other mounting structures can be used to extend through the light-emitting film layer 4 from the mounting area 322 and fixedly engage with the skeleton layer 5, so as to stably mount both the reflective film layer 3 and the light-emitting film layer 4 on the skeleton layer 5. In one embodiment, the thickness of the carrier layer 32 is about 0.6 mm. In this way, the strength and stiffness of the carrier layer 32 are relatively large compared with the texture layer 31 to stably support the optical ornament 2.

[0108] The installation area 322 is light-tight to avoid adversely affecting the display effect of the optical trim 2. In one embodiment, the light-transmitting area 321 is made of a transparent material, while the installation area 322 is made of an opaque material. Then, the light-transmitting area 321 and the installation area 322 are combined into a whole. The transparent material can be, for example, transparent polycarbonate (PC) or transparent polymethyl methacrylate (PMMA), etc., and the opaque material can be, for example, opaque PC, opaque ABS plastic, or PC-ABS plastic, etc. In other embodiments, the light-transmitting area 321 and the installation area 322 can be integrally made of the same light-transmitting material, and then an opaque blackening material is coated on the installation area 322. The blackening material can be, for example, black paint or dye. The transparent material, opaque material, and blackening material described here are well-known to those skilled in the art and will not be elaborated here.

[0109] The first decorative layer 33 is semi-transparent, so as to be able to weaken the intensity of the light that enters the interior of the optical trim 2 from the external environment through the reflective film layer 3. Thus, in the presence of external ambient light, the internal structure of the optical trim 2 is still invisible or almost invisible. This helps to improve the aesthetics of the optical trim 2 and also helps to improve the aesthetics of the vehicle 1. In one embodiment, the light transmittance of the first decorative layer 33 is between 10% and 15%, and such a first decorative layer 33 will not have an adverse effect on the second display effect of the optical trim 2.

[0110] In one embodiment, the first decorative layer 33 is obtained by modifying the inner surface (i.e., the surface of the carrier layer 32 away from the texture layer 31) or the outer surface (i.e., the surface of the carrier layer 32 close to the texture layer 31) of the carrier layer 32 to be semi-transparent. For example, the first decorative layer 33 can be a semi-transparent coating. In this way, the thickness of the first decorative layer 33 can be very small, which helps to reduce the thickness of the optical trim 2. In one embodiment, the first decorative layer 33 can be formed on the inner surface of the carrier layer 32 by a physical vapor deposition (PVD) coating process (for example, the coating material can be silicon dioxide, silver, zinc oxide, etc.), and a semi-transparent paint or nano-color paste can also be sprayed or screen-printed on the inner surface of the carrier layer 32 to form the first decorative layer 33.

[0111] In another embodiment, the first decorative layer 33 is a film layer provided on the inner side (i.e., the side of the carrier layer 32 away from the texture layer 31) of the carrier layer 32. For example, the first decorative layer 33 can be made of materials such as semi-transparent PC, PMMA, or glass.

[0112] Figure 6 Shows the texture layer 31 according to one embodiment. As Figure 6As shown, the texture layer 31 includes a transparent base layer 311 and a transparent texture structure 312. The texture structure 312 is carried on the base layer 311. In one embodiment, the texture structure 312 includes a plurality of texture units 313, and each texture unit 313 is different from each other (as Figure 7 shown). In this way, the reflection and refraction angles of each texture unit 313 with respect to the first light ray 201 incident on the texture layer are different, so that the user will observe different texture effects at different viewing angles (such different texture effects include different presented textures, or the texture is not visible to the human eye at certain specific viewing angles). Thus, the first display effect of the optical ornament 2 also has various forms, which further improves the richness of the display effect of the optical ornament 2. As an example, the texture effect includes at least one of a brushed texture, a grid texture, a gradient texture, a starry sky texture, a stone-like texture, a wood grain texture, a fabric texture, a landscape texture, a crystal texture, a lens texture, a three-dimensional relief, text, a graphic, a symbol, a number, a beacon, and a trademark. It should be understood that the number and form of the texture units can be selected according to actual needs.

[0113] In addition, both the base layer 311 and the texture structure 312 are transparent, so that the light emitted by the light blocking film layer 4 can pass through the texture layer 31, and thus the optical ornament 2 can present a second display effect. In one embodiment, the base layer 311 can be made of any one of transparent glass, transparent plastic, and transparent film, and can be set to have a color according to actual needs. As an option, the base layer 311 can be transparent PC, or transparent PMMA, transparent polyethylene terephthalate (PET), transparent polyolefin (PO), transparent polyvinyl chloride (PVC), transparent ethylene-vinyl acetate copolymer (EVA), and other suitable transparent composite plastics.

[0114] In one embodiment, the texture layer 31 includes a transparent texture structure layer 314 (as Figure 6 shown). The texture structure layer 314 is attached to the base layer 311 and has a texture structure 312 formed thereon. For example, the texture structure layer 314 can be made of a transparent resin-type material or a transparent solvent-type material, such as an optical glue including any one of photocurable glue (UV glue), thermosetting glue, unsaturated polyester glue, epoxy resin glue, polyurethane glue, and silicone glue. The texture structure 312 can be formed on any surface of the texture structure layer 314, that is, the texture structure 312 can be formed on the surface of the texture structure layer 314 facing the base layer 311 and / or the surface facing away from the base layer 311. As an option, the thickness of the texture structure layer 314 can be 1 to 999 nanometers, preferably 20 to 100 nanometers; or the thickness can be 1 to 999 micrometers, preferably 20 to 100 micrometers. In some embodiments, the texture structure layer 314 can have its own color, so that the first display effect of the optical ornament has a color.

[0115] In one embodiment, the texture structure 312 is directly formed on a surface of the base layer 311. For example, the texture structure 312 can be formed on the outer surface or the inner surface of the base layer 311. This helps to reduce the thickness of the texture layer 31, and thus reduces the thickness of the optical trim 2. In one embodiment, the texture structure 312 can be formed on a surface of the base layer 311 by means of laser engraving, machining, hot pressing, photolithography, etc.

[0116] For simplicity, the solution of the present application is described by taking the texture structure 312 formed on the texture structure layer 314 as an example.

[0117] It should be understood that the texture structure described herein refers to a 3D microscopic structure at the micron or even nanometer level, such as a concave structure form of microscopic V-grooves, arc grooves, etc., or a raised protrusion structure form. By using texture structures of different structural forms and / or the dimensions of various structural forms, a pseudo-three-dimensional texture effect, a relief effect, etc. can be formed. The texture structure can be formed on at least one surface of the texture structure layer by a transfer technique (e.g., optical glue transfer or imprinting). Additionally, depending on different requirements, the texture structure can also be produced by machining, chemical etching, photolithography, or other processes that can achieve the same result.

[0118] As Figure 7 and Figure 8 shown, a plurality of texture units 313 can be arranged continuously. Taking Figure 7 as an example, four texture units 313 are arranged continuously adjacent to each other and form a texture area 315. It should be understood here that "adjacent" means that the contour boundaries of each texture unit are connected, overlapped or close to each other, and the lines forming each contour boundary can be composed of the texture structure or formed by ink printing. Although the area of the surface occupied by each texture unit shown in the figure is approximately the same, the area of the surface covered by each texture unit can also be set to be different from each other according to needs. In some embodiments, a plurality of texture units can also be arranged to be spaced apart, thus forming a regular or irregular pattern. For example, as Figure 9 shown, a plurality of texture units 313 with different texture structures are arranged dispersedly. Additionally, as Figure 9 shown, the areas of these texture units 313 can be the same or different. In this way, the form of the first display effect of the optical trim 2 is more variable.

[0119] As an example, Figures 7 to 9 each texture unit is shown as being generally rectangular in shape. Depending on the application environment, other suitable shapes of the texture unit are feasible, such as circular or other polygons, etc. For example, Figure 10In the illustrated embodiment, the texture unit 313 is shown as being generally triangular in shape, and three texture units 313 form a generally triangular texture region 315. Thus, the texture region 315 composed of multiple texture units with different texture structures presents different visual effects from various angles under the reflection and refraction of the first light, such as presenting a virtual three-dimensional effect of light and dark surfaces. When multiple texture regions 315 are continuously arranged adjacent to each other, as Figure 11 shown, the first display effect of the optical ornament 2 presents a three-dimensional relief form, which enriches the visual sensory experience of the observer.

[0120] Figure 12 shows the display effects presented by beacon patterns in the form of switches that can be applied to the vehicle 1 with different texture designs. The beacon pattern can be divided into region P1 and region P2, and the peripheral region not covered by the beacon pattern can be divided into region P3. Thus, by forming different textures in different regions, more feasible combinations of display effects can be derived.

[0121] In some embodiments, region P1 and region P2 of the beacon pattern are covered by the same or different texture units or the same or different texture regions composed of multiple texture units. The covering method can be continuously arranged or dispersedly arranged, and the texture structures of region P1 and region P2 are dispersedly arranged. Region P3 is also covered with texture units or texture regions. The texture units or texture regions of region P1 and region P2 are different from those of region P3. In this way, under the illumination of the first light, region P1, region P2, and region P3 present different texture effects, thereby showing the beacon pattern. In the absence of the first light, the beacon pattern is not displayed. It should be understood that the beacon pattern can be of multiple types, such as Figure 13 shown, and those skilled in the art can select according to the actual situation.

[0122] In Figure 14In the embodiment of the texture layer 31 shown, in addition to including a base layer 311 and a texture structure layer 314 attached to the base layer 311, the texture layer 31 further includes a transparent coating layer 316. As a high-reflection film layer, the coating layer 316 is preferably disposed on the surface of the texture structure layer 314. However, without limitation, in some cases, it may also be disposed on a surface without a texture structure. Optionally, the coating layer 316 may be a physical vapor deposition (PVD) film layer formed by vacuum coating technologies such as evaporation coating or magnetron sputtering coating, and may be optionally a single-layer film or a multi-layer film stack, and the film thickness may be selected to be 10 to 50 microns. The coating layer includes a metal coating and a non-metal coating. Optionally, the coating layer may be a metal coating material such as indium or tin, or a non-metal coating material such as silicon dioxide. The coating layer generally has a metallic luster, thereby being able to increase the gloss of the optical ornament 2 and giving it a technological appearance with a metallic texture. In some embodiments, the coating layer may also have a color. Additionally, by providing the coating layer 316, when observing the optical ornament 2 from different angles, the texture structure 312 will produce bright and dark changes, which helps to enhance the texture effect of the optical ornament 2 and further enriches the display effect of the optical ornament 2.

[0123] In Figure 15A In the embodiment of the texture layer 31 shown, in addition to including a first base layer 311 and a texture structure layer 314 attached to the base layer 311, the texture layer 31 further includes a transparent pattern layer 317. In this embodiment, the pattern layer 317 can be directly attached to the texture structure layer 314 by processes such as ink printing to form patterns or textures such as beacons, patterns, and lines, as long as the ink material of the pattern layer does not fill the texture structure to affect the texture effect. Similarly, the pattern layer can be a single-layer film or a coating or a multi-layer film stack. In some embodiments, the ink material forming the pattern may have a color, thereby increasing the variation levels of the display effect of the optical ornament 2.

[0124] In one embodiment, as Figure 15BAs shown, the pattern layer 317 is attached to the texture structure layer 314 via the coating layer 316. It should be noted that the pattern on the pattern layer 317 has a hidden property. For example, when there is no backlight in the reflective film layer 3, the pattern on the pattern layer 317 is hidden. The backlight mentioned here refers to that the light source is arranged inside the reflective film layer 3 (i.e., on the side close to the light-emitting film layer 4) so that the light emitted by the light source propagates towards the pattern layer 317. When the backlight is provided, since both the coating layer 316 and the texture structure layer 314 are light-transmissive, the pattern on the pattern layer 317 will be displayed. Thus, combined with the texture structure on the texture structure layer 314, an observer observing from the outside of the optical ornament 2 can feel the texture effect in the presence of the first light, or can feel the visual effect of the combination of the texture and the pattern in the presence of the backlight. In other words, the display effect of the optical ornament 2 is more abundant.

[0125] In one embodiment, as Figure 15C shown, the pattern layer 317 and the texture structure layer 314 are respectively attached to two opposite surfaces of the base layer 311. In this way, in the presence of the first light and the backlight, the observer can also feel the visual effect of the combination of the texture and the pattern from the outside of the optical ornament 2.

[0126] As described above, the reflective film layer 3 can have a color effect through the color characteristics of the base layer and / or the texture structure and / or the coating layer and / or the pattern layer itself. In some embodiments, the color effect can also be obtained through a separate color layer. Alternatively, the color layer can be attached between any two adjacent layers among the base layer, the texture structure layer, the coating layer, and the pattern layer.

[0127] Figure 16 In the embodiment of the texture layer 31 shown, the texture layer 31 further includes a transparent color layer 318. The color layer 318 is attached to the surface of the texture structure layer 314, for example, sandwiched between the base layer 311 and the texture structure layer 314, so that the color effect can be directly visible from the outside of the optical ornament 2. The color layer can be a single-layer film or coating or composed of multiple stacked film layers, and can achieve a single color (such as blue, green, dark green, etc.) or multiple colors through printing or offset printing and other techniques, and can also be a gradient color, such as gradually transitioning from white to green, or gradually transitioning from gray to color (such as green, blue, etc.) and then to white, etc., thereby adjusting the color depth of the texture structure. For example, the color layer can be selected as an ink layer, and the layer thickness can be 1 to 100 microns, preferably 10 to 50 microns. By setting the color layer 318, the optical ornament 2 can have an appearance effect with bright colors. Combined with the texture structure layer 314 and / or the coating layer 316 and / or the pattern layer 317, the optical ornament 2 can present a more abundant display effect.

[0128] Figure 17Schematically shows another texture layer 31. As Figure 17 shown, the texture layer 31 includes a base layer 311 and a texture structure layer 314 attached to the base layer 311, a coating layer 316 attached to the texture structure layer 314, and a pattern layer 317 attached to the coating layer 316. A color layer 318 is disposed between the base layer 311 and the texture structure layer 314. In addition, a protective layer 319 is disposed on the surface of the pattern layer 317 facing away from the coating layer 316 to provide good service durability and reliability for the optical ornament 2.

[0129] Next, the light-emitting film layer 4 will be described.

[0130] As Figure 18 shown, the light-emitting film layer 4 includes a light guide film 41. In one embodiment, in the optical ornament 2, the light guide film 41 may be in contact with the skeleton layer 5. The light guide film 41 includes a light-emitting surface 412 and a bottom surface 413 opposite to the light-emitting surface 412. A plurality of optical microstructures 410 are formed in the light guide film 41 and arranged in a preset pattern 411 (as Figure 20 and Figure 21 shown).

[0131] Also as Figure 18 shown, the optical ornament 2 further includes a light source 204. The light guide film 41 further includes an edge surface connecting the light-emitting surface 412 and the bottom surface 413, and at least a part of the edge surface serves as an incident surface 414 of the light guide film 41. The light source 204 is disposed corresponding to the incident surface 414. In this way, the light-emitting film layer 4 is in the form of side-in type backlight, which helps to reduce the thickness of the optical ornament 2. In other embodiments, the light source 204 may also be disposed corresponding to the bottom surface 413 of the light guide film 41, so that the light-emitting film layer 4 is in the form of direct-lit backlight.

[0132] After the light source 204 is turned on, the light source 204 injects second light rays 202 into the light guide film 41. After passing through these optical microstructures 410, the second light rays 202 will change the propagation direction and emit from the light-emitting surface 412 (as Figure 18 shown). The light rays emitted from the light-emitting surface 412 further pass through the reflection film layer 3, so that the preset pattern 411 formed by the optical microstructures 410 can be displayed on the optical ornament 2 (that is, the optical ornament 2 presents a second display effect). It should be noted that the second light rays 202 that do not encounter the optical microstructures 410 still propagate in the light guide film 41 and will not emit from the light-emitting surface 412. Generally speaking, except for the area corresponding to the pattern 313, there is almost no outgoing light in the remaining area of the light-emitting surface 412, which makes the displayed preset pattern 411 clear and sharp.

[0133] It should be noted that the light guide film 41 is well-known to those skilled in the art. The optical microstructure 410 refers to a structure that affects the light transmission performance at the scale of visible light wavelength or sub-visible light wavelength. In one embodiment, the optical microstructure 410 can be formed in the light guide film 41 near the bottom surface 413 in various ways, such as by micro-nano imprinting, or by screen printing, etching, engraving, etc. In other embodiments, the optical microstructure 410 can also be formed at other positions in the light guide film 41, such as near the light-emitting surface 412. When using the light guide film 41, when the light does not encounter the optical microstructure 410, it will propagate in the light guide film 41 in a total reflection manner; after encountering the optical microstructure 410, the total reflection of the light is destroyed, and thus the light is emitted from the light-emitting surface 412. All of these are well-known to those skilled in the art and will not be elaborated here.

[0134] In Figure 22 In the embodiment of the light-emitting film layer 4 shown, a first reflective layer 415 is provided on the bottom surface 413 of the light guide film 41 (for example, the first reflective layer 415 is located between the light guide film 41 and the skeleton layer 5). The first reflective layer 415 will reflect the leakage light 303 generated at the optical microstructure 312 and directed towards the first reflective layer 415 back into the light guide film 41, and these lights will ultimately be emitted from the light-emitting surface 412 as well. In this way, the brightness of the preset pattern 411 displayed by the optical ornament 2 will be significantly improved, further improving the display effect of the optical ornament 2.

[0135] In one embodiment, the first reflective layer 415 can be formed on the bottom surface 311 of the light guide film 41 or on the corresponding surface of the skeleton layer 5. Those skilled in the art can select an appropriate reflective material according to the required final brightness of the pattern (for example, the reflective material can be reflective ink), which is not limited here. In one embodiment, the first reflective layer can be formed on the bottom surface 413 of the light guide film 41 or on the corresponding surface of the skeleton layer 5 by PVD, spraying or other appropriate processes, which is not limited here either. It should be understood that in the case where the skeleton layer 5 itself has good reflective performance (for example, when the skeleton layer 5 is white), the surface of the skeleton layer 5 in contact with the light guide film 41 can also serve as the first reflective layer. In this case, the optical ornament 2 does not need to be additionally configured with a separate first reflective layer.

[0136] In Figure 23In the embodiment of the light-emitting film layer shown, the light-emitting film layer 4 further includes a second modification layer 417. The second modification layer 417 is on one side of the bottom surface 413 of the light guide film 41, for example, between the light guide film 41 and the skeleton layer 5. The second modification layer 417 can be made of a material with a pattern and / or color (for example, a film sheet with a pattern and / or color). Since the film layer outside the second modification layer 417 is transparent, the user can directly observe the pattern and / or color on the second modification layer 417 from the outside of the optical ornament 2. This helps to further improve the display effect of the optical ornament 2.

[0137] Figure 24 Schematically shows another embodiment of the light-emitting film layer. As Figure 24 shown, the light-emitting film layer 4 has multiple layers of light guide films (for example, the first light guide film 431, the second light guide film 432, and the third light guide film 433), and a preset pattern is provided on each layer of the light guide film. The first light guide film 431, the second light guide film 432, and the third light guide film 433 are stacked. In addition, an independent light source 204 is provided for each layer of the light guide film, and each light source 204 can be independently controlled. In this way, the light source of any layer of the light guide film can be lit as needed, so that the optical ornament 2 displays the preset pattern of that layer of the light guide film. It is also possible to light the light sources of any two or more layers of the light guide film simultaneously as needed, so that the optical ornament 2 superimposes and displays the preset patterns of these light guide films. It is also possible to control the lighting or extinguishing of the light sources of two or more layers of the light guide film according to an appropriate timing sequence, so that the corresponding light guide film lights up or extinguishes according to this timing sequence, and in this way, the optical ornament 2 displays a dynamic pattern. This further enriches the display effect presented by the optical ornament 2. The control method of the light source is easily achieved by those skilled in the art and will not be elaborated here.

[0138] Figures 25a to 25g Schematically shows Figure 24 a display effect of the light-emitting film layer shown. When only the first light guide film 431 is lit, the optical ornament 2 shows the first pattern 434 on the first light guide film 431 (as Figure 25a shown). When only the second light guide film 432 is lit, the optical ornament 2 shows the second pattern 435 on the second light guide film 432 (as Figure 25b shown). When only the third light guide film 433 is lit, the optical ornament 2 shows the third pattern 436 on the third light guide film 433 (as Figure 25c shown). When the first light guide film 431 and the second light guide film 432 are lit simultaneously, the optical ornament 2 superimposes and shows the first pattern 434 and the second pattern 435 (as Figure 25d shown). When the first light guide film 431 and the third light guide film 433 are lit simultaneously, the optical ornament 2 superimposes and shows the first pattern 434 and the third pattern 436 (as Figure 25eAs shown). When the second light guide film 432 and the third light guide film 433 are lit simultaneously, the optical ornament 2 simultaneously displays the second pattern 435 and the third pattern 436 (as Figure 25f shown). When the first light guide film 431, the second light guide film 432, and the third light guide film 433 are lit simultaneously, the optical ornament 2 superimposes and displays the first pattern 434, the second pattern 435, and the third pattern 436 (as Figure 25g shown). When the first light guide film 431, the second light guide film 432, and the third light guide film 433 are lit in a cycle, the optical ornament 2 will cyclically display the first pattern 434, the second pattern 435, and the third pattern 436, so that the optical ornament 2 presents a display effect of a dynamic pattern.

[0139] Also as Figure 24 shown, between the first light guide film 431 and the second light guide film 432, and between the second light guide film 432 and the third light guide film 433, a transparent adhesive 437 is filled. In this way, the first light guide film 431, the second light guide film 432, and the third light guide film 433 are bonded into a whole through the adhesive 437, so that these film layers will not move relative to each other. Thereby, accidental misalignment of these film layers is avoided, and further, deformation of the pattern displayed by the optical ornament 2 or display of an incorrect pattern is avoided. In addition, these film layers being bonded into a whole also avoids wear between these film layers or abnormal noise generated by the optical ornament 2. It should be noted that the adhesive 437 does not affect the propagation of light in the film layer and allows the light whose propagation direction is changed after passing through the optical microstructure 410 to pass through. In one embodiment, the adhesive 437 can be any one of an optical adhesive (i.e., OCA adhesive), a hot melt adhesive, and an aqueous adhesive, which are well known to those skilled in the art and will not be elaborated here. Of course, those skilled in the art can also, according to the actual situation, closely fit these film layers together by other means, such as by laser welding, which is not limited here.

[0140] In some other embodiments, there may also be a gap between adjacent light guide films, and they are only connected to each other at some preselected positions (for example, they can be connected by laser welding).

[0141] Figure 26 Schematically shows an embodiment of the light source 204. The light source 204 includes a light emitting device 601, a condenser 602, and a lamp box 610 that houses the condenser 602.

[0142] In one embodiment, the light-emitting device 601 is an LED lamp bead. The LED lamp bead has a small volume, facilitating its application to the optical trim 2 with a small thickness. Additionally, the lighting and extinguishing of the LED lamp bead are also easy to control. In one embodiment, the light-emitting device 601 can emit colored light, which helps the optical trim 2 to further present a special display effect. In other embodiments, the light-emitting device 601 can also be a laser source.

[0143] The condenser 602 includes an incident end 603, an exit end 604 remote from the incident end 603, and a side wall 606 connected between the incident end 603 and the exit end 604. The light-emitting device 601 is arranged to correspond to the incident end 603 of the condenser 602 and the size of the light-emitting device 601 matches the size of the incident end 603, so that the light emitted by the light-emitting device 601 can enter the condenser 602. The exit end 604 of the condenser 602 corresponds to the incident surface 414 of the light guide film 41, and the size of the exit end 604 matches the size of the incident surface 414. In this way, the condenser 602 can make the light emitted by the light-emitting device 601 enter the light guide film 41 as much as possible. In the case where the size of the light-emitting device 601 does not match the size of the incident surface 414 of the light guide film 41, it is particularly advantageous to provide the condenser 302. For example, if the size of the light-emitting device 601 is larger than the size of the incident surface 414 of the light guide film 41, the condenser 602 is generally conical, with the large end facing the light-emitting device 601 and the small end facing the light guide film 41, so as to guide the light emitted by the light-emitting device 601 into the light guide film 41 as much as possible. It should be understood that in the case where the size of the light-emitting device 601 matches the size of the incident surface 414 of the light guide film 41, the condenser 602 may not be provided.

[0144] The lamp box 610 has a receiving cavity 611. An assembly opening 612 communicating with the receiving cavity 611 is formed at the first end of the lamp box 610, and a light-emitting hole 613 communicating with the receiving cavity 611 is formed at the second end of the lamp box 610. The light-emitting device 601 is located in the receiving cavity 611 and close to the assembly opening 612. The condenser 602 is arranged in the receiving cavity 611, and the incident end 603 of the condenser 602 corresponds to the light-emitting device 612, and the exit end 604 corresponds to the light-emitting hole 613. A second reflective layer (not shown in the figure) is provided on the inner surface of the receiving cavity 611. The second reflective layer reflects the light emitted from the side wall 606 of the condenser 602 back into the condenser 602, which helps to increase the amount of light entering the light guide film 41 and thus helps to increase the brightness of the optical trim 2.

[0145] Also as Figure 26As shown, the light source 60 further includes an end cap 620. The end cap 620 is disposed at the second end of the lamp box 610. A through hole 621 corresponding to the light exit hole 613 is formed in the end cap 620. The size of the through hole 621 matches the size of the incident surface 414 of the light guide film 41, so as to facilitate the alignment of the incident surface 414 of the light guide film 41 with the through hole 621, and further contribute to the injection of the light emitted from the exit end 604 of the condenser 604 into the light guide film 41. The lamp box 610 and the end cap 620 protect the condenser 602 and the light emitting device 601, and also facilitate the assembly of the condenser 602 and the light emitting device 601.

[0146] In one embodiment, as Figure 26 shown, the optical trim 2 may further include a circuit board 605 for powering the light emitting device 601. When assembling the optical trim 2, the assembly opening 612 is fitted with the circuit board 605 to accommodate the light emitting device 601 into the accommodation cavity 611.

[0147] Figure 27 Schematically shows another embodiment of the light source. As Figure 27 shown, the light source 204 also includes a light emitting device 601, a condenser 602, and a lamp box 610. The length of the lamp box 610 of the light source 204 is greater than the length of the condenser 602, and the section of the light guide film 41 including the incident surface 414 extends into the lamp box 610. Thus, the second type of light source 204 does not require an end cap.

[0148] Figure 28 Schematically shows a state where a plurality of Figure 27 the shown light sources are combined together. As Figure 28 shown, a plurality of light sources 204 are respectively aligned with a plurality of stacked light guide films 41. For example, a plurality of light emitting devices 601 (and corresponding condensers 602) are respectively aligned with a plurality of light guide films 41 to separately provide light to each light guide film 41. Adjacent light emitting devices 601 (and condensers 602) are spaced apart by the lamp box 610 to avoid light crosstalk between them.
