Description

Technical Field

[0001] This invention relates to the field of vehicle accessories, specifically to an abyss ambient lighting structure, a vehicle window, and a vehicle. Background Technology

[0002] With the continuous development of automotive technology, users' requirements for vehicle lighting and display technologies (such as the image display function of the panoramic sunroof) are also constantly increasing. Currently, panoramic sunroof structures with lighting and display functions mostly adopt two types: mirror-printed displays and functional film displays. like Figure 1 As shown, this is an ambient light structure with mirror printing display. Generally, a mirror printing ink layer 40 capable of forming a preset pattern is provided on the bonding surface of the inner glass 20 and the outer glass 10. The inner glass 20 and the outer glass 10 are bonded together by a thermoplastic intermediate layer 30. A light source 50 is provided on the inner glass 20. The light emitted by the light source 50 shines on the mirror printing ink layer 40 and is reflected back into the vehicle, thereby realizing the planar display of the image.

[0003] like Figure 2 As shown, this is an ambient light structure with a functional film display. An LED film 60 is disposed between the inner glass 20 and the outer glass 10. A thermoplastic interlayer 30 is disposed between the LED film 60 and the inner glass 20 and between the LED film 60 and the outer glass 10. The inner glass 20, the LED film 60 and the outer glass 10 are bonded together as a whole by the thermoplastic interlayer 30. During use, the image can be displayed in a planar manner through the LED film 60.

[0004] As can be seen from the display function of the ambient lighting structure described above, the existing vehicle panoramic ambient lighting can only achieve planar image display, usually presenting fixed patterns (such as starry sky), lacking three-dimensionality and dynamic changes, and cannot meet the user's higher requirements for ambient lighting image display (such as not being able to obtain the depth of three-dimensional optical illusion). Therefore, the existing vehicle panoramic ambient lighting lacks the ability to display three-dimensional images and cannot further enhance the user's viewing experience.

[0005] Therefore, this invention proposes an abyss-themed ambient lighting structure, a car window, and a vehicle to overcome the shortcomings of the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide an abyss-themed ambient light structure, a car window, and a vehicle, which can increase the three-dimensional depth of the displayed image, enhance the product's ability to create atmosphere, have higher practicality and image display effect, and effectively improve the user's viewing experience.

[0007] The objective of this invention can be achieved in the following ways: This invention provides an abyss-themed ambient light structure, the abyss-themed ambient light structure comprising: A first dimming unit, wherein the first dimming unit is at least used for reflecting light; A second dimming unit is used to simultaneously reflect and transmit light, and there is a gap between the second dimming unit and the first dimming unit. A directional light guiding structure through which light rays are directed into the spaced space; In this process, at least a portion of the light rays can be reflected multiple times within the space between the second dimming unit and the first dimming unit, and each time the light rays reflected from the first dimming unit to the second dimming unit, a portion of the light rays are transmitted from the second dimming unit to the outside of the space.

[0008] In a preferred embodiment of the present invention, the abyss ambient light structure further includes a light source, which is disposed on one of the first dimming unit and the second dimming unit, or the light source is disposed between the first dimming unit and the second dimming unit.

[0009] In a preferred embodiment of the present invention, both the first dimming unit and the second dimming unit are used to simultaneously reflect and transmit light, so that each time light is reflected to the first dimming unit and the second dimming unit, a portion of the light is transmitted by the first dimming unit and the second dimming unit to the outside of the space.

[0010] In a preferred embodiment of the present invention, the first dimming part is a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer.

[0011] In a preferred embodiment of the present invention The visible light reflectance of the first dimming unit is greater than or equal to 85%; The visible light reflectance of the second dimming unit is greater than or equal to 30% and less than or equal to 80%, and the visible light transmittance of the second dimming unit is greater than or equal to 20% and less than or equal to 70%. The light is reflected to the second dimming unit through the first dimming unit, and each time the light is reflected to the second dimming unit, a portion of the light is transmitted from the second dimming unit to the outside of the space.

[0012] In a preferred embodiment of the present invention, the first dimming unit is a fully reflective glass layer or a fully reflective plastic layer.

[0013] In a preferred embodiment of the present invention, the second dimming part is a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer.

[0014] In a preferred embodiment of the present invention, the first dimming unit includes a first transparent support layer and a first dimming layer capable of adjusting the visible light reflectivity. By adjusting the visible light reflectivity of the first dimming layer, the first dimming unit can switch between a state of total reflection of light and a state of semi-transmission and semi-reflection of light.

[0015] In a preferred embodiment of the present invention, the second dimming unit includes a second transparent support layer and a second dimming layer capable of adjusting the reflectivity of visible light. By adjusting the reflectivity of the second dimming layer, the reflectivity of the visible light of the second dimming unit is adjusted.

[0016] In a preferred embodiment of the present invention, the first dimming unit includes a transparent first conductive support layer and a second conductive support layer, and a functional layer is disposed between the first conductive support layer and the second conductive support layer. By energizing the functional layer, the visible light reflectivity of the functional layer is changed, so that the first dimming unit can switch between a state of total internal reflection of light and a state of partial transmission and partial reflection of light.

[0017] In a preferred embodiment of the present invention, the edge of the first dimming part and the edge of the second dimming part are connected by a directional light guide structure, and the light source is disposed on the side of the directional light guide structure away from the interval space.

[0018] In a preferred embodiment of the present invention, the first dimming part or the second dimming part has a light-passing hole, and a directional light guiding structure is provided at the light-passing hole. The light source is disposed on the side of the directional light guiding structure away from the interval space.

[0019] The present invention provides a vehicle window having the aforementioned abyss ambient light structure.

[0020] The present invention provides a vehicle having the aforementioned window.

[0021] Based on the above, the features and advantages of the abyss ambient light structure, window, and vehicle of the present invention are as follows: The device is equipped with a first dimming unit that can reflect light and a second dimming unit that can simultaneously reflect and transmit light. A gap space is left between the second dimming unit and the first dimming unit. By emitting light into the gap space, based on the principle of an abyss mirror, at least part of the light can be reflected multiple times in the gap space between the second dimming unit and the first dimming unit. Each time the light reflected from the first dimming unit to the second dimming unit, a portion of the light can be transmitted from the second dimming unit to the outside of the gap space (i.e., the human eye side). Thus, a three-dimensional image can be displayed on the human eye side, effectively enhancing the product's technological feel and atmosphere creation capabilities, and effectively improving the user's viewing experience.

[0022] Importantly, in this invention, light enters the space through the directional light guide structure, which not only facilitates the concentration of light and the display of images, but also, due to the directional light guide structure, the light source needs to be external (i.e., the light source is placed outside the space), which is more conducive to reducing the size of the product. There is no need to limit the thickness of the product by providing installation space for the light source, which effectively enhances the practicality of the product. In addition, the external placement of the light source makes it easier to disassemble and replace, and has better adaptability. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0027] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] The abyss mirror principle used in this invention creates visual depth by utilizing the infinite reflection and attenuation of light between two mirror layers, such as... Figure 3 and Figure 4As shown, the abyss mirror includes alternating double-reflective mirrors (where the double-reflective mirrors are semi-transparent and semi-reflective) and ordinary mirrors (where the ordinary mirrors are total reflection mirrors). A light source is placed between the double-reflective mirrors and the ordinary mirrors, located to the side of both. Light is emitted from the light source towards the ordinary mirrors, and the light is reflected multiple times at an angle between the inner surfaces of the double-reflective and ordinary mirrors. Because some light penetrates the double-reflective mirrors and enters the viewer's eye with each reflection, and because the light intensity decreases exponentially, a gradual change from bright to dark is created, giving the user a three-dimensional structure (e.g., a three-dimensional effect). Figure 4 (as seen in the infinitely deep tunnel pattern displayed in the image), thus, the Abyss Mirror can use optical principles to create a realistic three-dimensional sense of depth, giving the displayed pattern a unique and profound visual effect.

[0030] Implementation Method 1

[0031] like Figures 5 to 10 As shown, the present invention provides an abyss-themed ambient light structure, which includes a first dimming unit 1, a second dimming unit 2, a light source 4, and a directional light guiding structure 8. At least the first dimming unit 1 is used to reflect light, and at least the second dimming unit 2 is used to simultaneously reflect and transmit light. There is a gap space 3 between the second dimming unit 2 and the first dimming unit 1. The light source 4 is disposed on one of the first dimming unit 1 and the second dimming unit 2, or the light source 4 is disposed between the first dimming unit 1 and the second dimming unit 2. The light emitted by the light source 4 is directed into the gap space 3 through the directional light guiding structure 8. Based on the principle of an abyss mirror, at least a portion of the light emitted by the light source 4 is first projected onto the first dimming unit 1, which then reflects at least a portion of the light to the second dimming unit 2. Within the gap space 3, at least a portion of the light emitted by the light source 4 undergoes multiple reflections within the gap space 3 between the second dimming unit 2 and the first dimming unit 1. Each time the light reflected from the first dimming unit 1 to the second dimming unit 2, a portion of the light is transmitted through the second dimming unit 2 to the outside of the gap space 3 (i.e., the human eye side). Because the light undergoes transmission during its passage through the gap space 3, the light reflected from the first dimming unit 1 to the second dimming unit 2 is attenuated each time, thus displaying a three-dimensional image on the human eye side and enhancing the user's viewing experience.

[0032] Furthermore, in this invention, the light emitted by the light source 4 is directionally guided into the space 3 through the directional light guide structure 8. This not only facilitates the concentration of light and the display of images, but also, due to the setting of the directional light guide structure 8, the light source 4 needs to be external (i.e., the light source 4 is set outside the space 3), which is more conducive to reducing the size of the product. There is no need to limit the thickness of the product due to providing installation space for the light source 4, which effectively enhances the practicality of the product. In addition, the external placement of the light source 4 makes it easier to disassemble and replace, and has better adaptability.

[0033] In this invention, the light source 4 can be, but is not limited to, light-emitting diodes, miniLEDs (sub-millimeter light-emitting diodes), or microLEDs (micrometer light-emitting diodes), etc. The color and quantity of the light source 4 can be set according to the actual situation. The light source 4 can be in the form of a dot or a light strip. Depending on the form of the light source 4, different patterns can be displayed in actual application.

[0034] In an optional embodiment of the present invention, the light source 4 may be disposed between the first dimming unit 1 and the second dimming unit 2. For example... Figures 5 to 10 As shown, the edge of the first dimming unit 1 and the edge of the second dimming unit 2 are connected by a directional light guide structure 8, and the light source 4 is disposed on the side of the directional light guide structure 8 away from the spacing space 3 (i.e., the outside of the spacing space 3).

[0035] Specifically, such as Figures 5 to 10 As shown, a support portion 5 is sealed between the edge of the first dimming unit 1 and the edge of the second dimming unit 2. A directional light guide structure 8 is located within the support portion 5, and the support portion 5 seals the edge of the first dimming unit 1 and the edge of the second dimming unit 2 together. Additionally, as... Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, the light source 4 is mounted on the support 5. The support 5 provides a stable, sealed connection between the first dimming unit 1 and the second dimming unit 2, and also provides a mounting position for the light source 4. In this embodiment, the mounting position of the light source 4 does not restrict the product's thickness (or the width of the spacing space 3) due to providing mounting space for the light source 4 (the width can be reduced by several millimeters compared to the traditional spacing between two pieces of glass). This allows for a slimmer, lighter design, effectively enhancing the product's practicality.

[0036] In this embodiment, as Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, the light source 4 is fixed to the support 5 and located outside the space 3. At least part of the light emitted by the light source 4 passes through the support 5 and enters the space 3. During this process, the light rays pass through the directional light guide structure 8 on the support 5, changing their direction of entry into the space 3, thereby achieving guidance control of the light rays. The directional light guide structure 8 is a prism and / or lens disposed inside the support 5.

[0037] Specifically, such as Figure 11As shown, the directional light guiding structure 8 includes a microlens 801 (or a microlens array) and a light guide post 802. The microlens 801 and the light guide post 802 are sequentially arranged along the light emission direction. The light guide post 802 has a horizontal light guiding section 8021 and an oblique light guiding section 8022 sequentially connected along the light transmission direction. One end of the horizontal light guiding section 8021 faces the convex end face of the microlens 801 and maintains a certain distance, so that the light converged by the microlens 801 enters the horizontal light guiding section 8021. The other end of the light guide section 8021 is connected to one end of the oblique light guide section 8022. The other end of the oblique light guide section 8022 extends obliquely towards the first dimming unit 1 or the second dimming unit 2. The converging light entering the horizontal light guide section 8021 passes through the horizontal light guide section 8021 and the oblique light guide section 8022 in sequence and is concentrated and emitted towards the first dimming unit 1 or the second dimming unit 2, thereby achieving the convergence and directional emission of light, improving the utilization rate of light, and thus enhancing the display effect of the pattern. In addition, by setting the directional light guide structure 8, the light source 4 can be placed outside the interval space 3, making it easier to maintain and replace the light source 4; moreover, it is precisely because of the setting of the directional light guide structure 8 that the width of the interval space 3 is not affected by the setting of the light source 4, realizing the thin and light design of the product.

[0038] The support portion 5 can be a segmented structure, meaning multiple support portions 5 are arranged sequentially along the edges of the first dimming portion 1 and the second dimming portion 2; or the support portion 5 can be a single piece, meaning a single support portion 5 is arranged circumferentially along the edges of the first dimming portion 1 and the second dimming portion 2. The actual structure and placement of the support portion 5 can be determined according to the actual installation position of the light source 4. The support portion 5 can be a strip or block structure formed of materials such as PMMA (acrylic), PC (polycarbonate), glass, or optical adhesive; the thickness of the support portion 5 can be, but is not limited to, 1-12mm (can be set according to requirements).

[0039] In another optional embodiment of the present invention, the light source 4 may be disposed on one of the first dimming unit 1 and the second dimming unit 2. For example... Figure 7 and Figure 9 As shown, the first dimming part 1 and the position near its edge or the second dimming part 2 and the position near its edge have a light-passing hole 6. A directional light guide structure 8 is provided at the light-passing hole 6. The light source 4 is provided on the side of the directional light guide structure 8 away from the interval space 3 (i.e., the outside of the interval space 3).

[0040] Specifically, such as Figure 7 and Figure 9As shown, a light-transmitting part 7 is sealed at the light-passing hole 6, and a directional light-guiding structure 8 is located inside the light-transmitting part 7. The light source 4 is disposed on the light-transmitting part 7. The light-transmitting part 7 not only seals the light-passing hole 6, preventing external moisture and impurities from entering the space 3, but also ensures that the light emitted by the light source 4 can smoothly pass through the light-passing hole 6 into the space 3. Simultaneously, it provides a mounting position for the light source 4, achieving multiple effects at once. In this embodiment, the position of the light source 4 avoids the edge of the product, making product installation easier.

[0041] In this embodiment, as Figure 7 and Figure 9 As shown, the light source 4 is fixed to the light-transmitting part 7 and located outside the space 3. At least part of the light emitted by the light source 4 passes through the light-transmitting part 7 and enters the space 3. During this process, the light rays pass through the directional light-guiding structure 8 on the light-transmitting part 7, changing their direction of entry into the space 3, thereby achieving guidance control of the light rays. The directional light-guiding structure 8 is a prism and / or lens disposed inside the light-transmitting part 7.

[0042] Specifically, such as Figure 11 As shown, the directional light guiding structure 8 includes a microlens 801 (or a microlens array) and a light guide post 802. The microlens 801 and the light guide post 802 are sequentially arranged along the light emission direction. The light guide post 802 has a horizontal light guiding section 8021 and an oblique light guiding section 8022 sequentially connected along the light transmission direction. One end of the horizontal light guiding section 8021 faces the convex end face of the microlens 801 and maintains a certain distance, so that the light converged by the microlens 801 enters the horizontal light guiding section 8021. The other end of the light guide section 8021 is connected to one end of the oblique light guide section 8022. The other end of the oblique light guide section 8022 extends obliquely towards the first dimming unit 1 or the second dimming unit 2. The converging light entering the horizontal light guide section 8021 passes through the horizontal light guide section 8021 and the oblique light guide section 8022 in sequence and is concentrated and emitted towards the first dimming unit 1 or the second dimming unit 2, thereby achieving the convergence and directional emission of light, improving the utilization rate of light, and thus enhancing the display effect of the pattern. In addition, by setting the directional light guide structure 8, the light source 4 can be placed outside the interval space 3, making it easier to maintain and replace the light source 4; moreover, it is precisely because of the setting of the directional light guide structure 8 that the width of the interval space 3 is not affected by the setting of the light source 4, realizing the thin and light design of the product.

[0043] In this invention, depending on the actual display needs, the abyss ambient light structure can achieve single-sided display of the pattern or double-sided display of the pattern.

[0044] When the abyss ambient light structure achieves unilateral display of the pattern, the visible light reflectivity of the first dimming unit 1 is greater than or equal to 85%; and the visible light reflectivity of the second dimming unit 2 is greater than or equal to 30% and less than or equal to 80%, and the visible light transmittance of the second dimming unit 2 is greater than or equal to 20% and less than or equal to 70%. This allows light to be reflected from the first dimming unit 1 to the second dimming unit 2, and ensures that a portion of the light reflected to the second dimming unit 2 is transmitted through the second dimming unit 2 to the outside of the spacing space 3 each time. Alternatively, the first dimming unit 1 and the second dimming unit 2 can be interchanged, i.e., the visible light reflectivity of the second dimming unit 2 is greater than or equal to 85%; and the visible light reflectivity of the first dimming unit 1 is greater than or equal to 30% and less than or equal to 80%, and the visible light transmittance of the first dimming unit 1 is greater than or equal to 20% and less than or equal to 70%. In this case, a portion of the light will be transmitted through the first dimming unit 1 to the outside of the spacing space 3. The following explanation assumes that the first dimming unit 1 is used only for reflecting light, and the second dimming unit 2 is used only for simultaneously reflecting and transmitting light.

[0045] In an optional embodiment of the present invention, both the first dimming unit 1 and the second dimming unit 2 can be single-layer structures. For example... Figure 5 As shown, the first dimming unit 1 is a fully reflective glass layer or a fully reflective plastic layer, and the second dimming unit 2 is a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer. In this case, the pattern can be displayed on one side.

[0046] In one specific embodiment of the present invention, such as Figure 5As shown, a first dimming unit 1 and a second dimming unit 2 are spaced apart, forming a gap space 3 between them. A support unit 5 is sealed between the edge of the first dimming unit 1 and the edge of the second dimming unit 2, and a light source 4 is fixedly mounted on the support unit 5. The first dimming unit 1 is a fully reflective glass layer or a fully reflective plastic layer, and its visible light reflectance needs to reach greater than 85% (within this range, the product's requirement for total light reflection is met). The material used for the first dimming unit 1 can be laminated glass, tempered glass, or transparent plastic (i.e., the material of the first dimming unit 1 is, but is not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass, or transparent plastic). Of course, in other embodiments, the visible light reflectance can also be adjusted by coating (coating thickness of 100-500nm), laminating (film thickness less than or equal to 1mm), applying a coating layer, or laminating the transparent material, ensuring that the visible light reflectance of the first dimming unit 1 is greater than 85%. The second dimming unit 2 is a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer with a visible light reflectance between 30% and 80%. The material used for the second dimming unit 2 can be laminated glass, tempered glass, or transparent plastic (i.e., the material of the first dimming unit 1 is, but is not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass, or transparent plastic). Of course, in some other embodiments, the visible light reflectance can also be adjusted by coating (coating thickness of 100-500nm), applying a film (film thickness less than or equal to 1mm), setting a coating layer, or laminating a film on the transparent material, so as to ensure that the visible light reflectance of the second dimming unit 2 is between 30% and 80%.

[0047] When the abyss ambient light structure achieves dual-sided display of the pattern, both the first dimming unit 1 and the second dimming unit 2 are used to simultaneously reflect and transmit light, so that each time the light reflected to the first dimming unit 1 and the second dimming unit 2, a portion of the light is transmitted by the first dimming unit 1 and the second dimming unit 2 to the outside of the space 3.

[0048] In an optional embodiment of the present invention, both the first dimming unit 1 and the second dimming unit 2 can be single-layer structures. For example... Figure 6 As shown, the first dimming unit 1 is a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer, and the second dimming unit 2 is also a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer. In this case, the pattern can be displayed on both sides.

[0049] In one specific embodiment of the present invention, such as Figure 6As shown, a first dimming unit 1 and a second dimming unit 2 are spaced apart, forming a gap space 3 between them. A support unit 5 is sealed between the edge of the first dimming unit 1 and the edge of the second dimming unit 2, and a light source 4 is fixedly mounted on the support unit 5. The first dimming unit 1 is a semi-transparent, semi-reflective glass layer or a semi-transparent, semi-reflective plastic layer with a visible light reflectance between 30% and 80%. The material used for the first dimming unit 1 can be laminated glass, tempered glass, or transparent plastic (i.e., the material of the first dimming unit 1 is, but is not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass, or transparent plastic). Of course, in other embodiments, the visible light reflectance can also be adjusted by coating (coating thickness of 100-500 nm), laminating (film thickness less than or equal to 1 mm), applying a coating layer, or laminating the transparent material, ensuring that the visible light reflectance of the first dimming unit 1 is between 30% and 80%. The second dimming unit 2 is a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer with a visible light reflectance between 30% and 80%. The material used for the second dimming unit 2 can be laminated glass, tempered glass, or transparent plastic (i.e., the material of the first dimming unit 1 is, but is not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass, or transparent plastic). Of course, in some other embodiments, the visible light reflectance can also be adjusted by coating (coating thickness of 100-500nm), applying a film (film thickness less than or equal to 1mm), setting a coating layer, or laminating a film on the transparent material, so as to ensure that the visible light reflectance of the second dimming unit 2 is between 30% and 80%.

[0050] In another specific embodiment of the present invention, such as Figure 7As shown, a first dimming unit 1 and a second dimming unit 2 are spaced apart, forming a gap space 3 between them. A support portion 5 is sealed between the edge of the first dimming unit 1 and the edge of the second dimming unit 2. A light-passing hole 6 is located near the edge of the first dimming unit 1, and a light-transmitting portion 7 is sealed at the light-passing hole 6. A light source 4 is disposed in the light-transmitting portion 7 and located outside the gap space 3. In this embodiment, the light emitted by the light source 4 penetrates the light-transmitting portion 7 and directly enters the gap space 3, illuminating the second dimming unit 2. This improves the utilization rate of light and ensures that the light can undergo more reflections within the gap space 3 between the first dimming unit 1 and the second dimming unit 2, thereby improving the image display effect. The first dimming unit 1 is a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer with a visible light reflectance between 30% and 80%. The material used for the first dimming unit 1 can be laminated glass, tempered glass, or transparent plastic (i.e., the material of the first dimming unit 1 is, but is not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass, or transparent plastic). Of course, in some other embodiments, the visible light reflectance can also be adjusted by coating (coating thickness of 100-500nm), applying film (film thickness less than or equal to 1mm), setting coatings, or laminating, etc., to ensure that the visible light reflectance of the first dimming unit 1 is between 30% and 80%. The second dimming unit 2 is a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer with a visible light reflectance between 30% and 80%. The material used for the second dimming unit 2 can be laminated glass, tempered glass, or transparent plastic (i.e., the material of the first dimming unit 1 is, but is not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass, or transparent plastic). Of course, in some other embodiments, the visible light reflectance can also be adjusted by coating (coating thickness of 100-500nm), applying a film (film thickness less than or equal to 1mm), setting a coating layer, or laminating a film on the transparent material, so as to ensure that the visible light reflectance of the second dimming unit 2 is between 30% and 80%.

[0051] In an optional embodiment of the present invention, the first dimming unit 1 and / or the second dimming unit 2 may also be a multilayer composite structure. For example... Figures 8 to 10As shown, the first dimming unit 1 includes a first transparent support layer 101 and a first dimming layer 102 capable of adjusting the visible light reflectance by changing its transparency. The first transparent support layer 101 and the first dimming layer 102 are stacked and connected by a first adhesive layer 103. By adjusting the visible light reflectance of the first dimming layer 102, the first dimming unit 1 can switch between a state of total internal reflection and a state of partial transmission and partial reflection of light. Similarly, the second dimming unit 2 includes a second transparent support layer 201 and a second dimming layer 202 capable of adjusting the visible light reflectance. The second transparent support layer 201 and the second dimming layer 202 are stacked and connected by a second adhesive layer 203. By adjusting the visible light reflectance of the second dimming layer 202, the visible light reflectance of the second dimming unit 2 can be adjusted. In actual production, the first dimming unit 1 and the second dimming unit 2 can be set to the above-mentioned multi-layer composite structure at the same time. Of course, one of the first dimming unit 1 and the second dimming unit 2 can be set to the above-mentioned multi-layer composite structure, and the other can be set to a single-layer structure.

[0052] In one specific embodiment of the present invention, the first dimming layer 102 and the second dimming layer 202 can switch between a state of total internal reflection of light and a state of semi-transmission and semi-reflection of light to meet the adjustment of different depth effects of image display; in addition, according to actual needs, the first dimming layer 102 and the second dimming layer 202 can also be adjusted to a visible light transmittance greater than 90% (that is, to make the first dimming part 1 and the second dimming part 2 transparent respectively), thereby achieving the effect of panoramic glass so that passengers inside the vehicle can see the situation outside the vehicle.

[0053] In one specific embodiment of the present invention, such as Figure 8As shown, a first dimming unit 1 and a second dimming unit 2 are spaced apart. The first dimming unit 1 includes a first transparent support layer 101 and a first dimming layer 102 stacked together, connected by a first adhesive layer 103. The second dimming unit 2 includes a second transparent support layer 201 and a second dimming layer 202 stacked together, connected by a second adhesive layer 203. A gap space 3 is formed between the first dimming layer 102 and the second dimming layer 202. A support portion 5 is sealed between the edge of the first dimming layer 102 and the edge of the second dimming layer 202, and a light source 4 is fixedly mounted on the support portion 5. Both the first transparent support layer 101 and the second transparent support layer 201 are transparent layers (such as colorless transparent layers, colored transparent layers, or multicolored transparent layers), and neither the first transparent support layer 101 nor the second transparent support layer 201 affects the transmission of light. The first transparent support layer 101 and the second transparent support layer 201 may be made of, but are not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass or transparent plastic.

[0054] Preferably, both the first transparent support layer 101 and the second transparent support layer 201 are made of rigid transparent plastic. Specific materials may be one or more of polyethylene, polypropylene, polycarbonate, polymethyl methacrylate, polystyrene, polyamide, polyester, and polyvinyl chloride.

[0055] The first adhesive layer 103 and the second adhesive layer 203 are used to achieve the functions of bonding and joining sheets. The thickness of the first adhesive layer 103 and / or the second adhesive layer 203 is less than 1 μm. The first adhesive layer 103 and the second adhesive layer 203 may be made of materials such as, but not limited to, polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU), or optical adhesive (OCA, OCR), with optical adhesive (OCA, OCR) being preferred.

[0056] In this design, both the first dimming layer 102 and the second dimming layer 202 can be formed by embedding dimming components (such as electroreflective films or PDLCs) within the interlayer of a flexible conductive film. In practical use, when the first dimming layer 102 is powered on, it can be adjusted from a transparent state to a reflective state; when the first dimming layer 102 is de-powered, it can change from a reflective state to a transparent state. The visible light reflectance of both the first dimming layer 102 and the second dimming layer 202 can be adjusted within the range of 10%-90%, thereby achieving dimming and abyss-themed pattern display effects in conjunction with the light source 4.

[0057] In some scenarios where only one-sided display is required, the first dimming unit 1 may consist of a first transparent support layer 101 and a first dimming layer 102 stacked together. The first transparent support layer 101 and the first dimming layer 102 are connected by a first adhesive layer 103. The second dimming unit 2 uses a semi-transparent and semi-reflective glass layer or a semi-transparent and semi-reflective plastic layer. Alternatively, the visible light reflectance can be adjusted on a fully transparent glass layer or plastic layer by means of coating (coating thickness of 100-500nm), film application (film thickness less than or equal to 1mm), setting a coating layer, or lamination, so that the visible light reflectance of the second dimming unit 2 is between 30% and 80%. In actual use, the first dimming layer 102 is energized to change it from a transparent state to a reflective state, so that light can be reflected multiple times in the space 3 between the first dimming part 1 and the second dimming part 2. Each time the light reflected from the first dimming part 1 to the second dimming part 2, a portion of the light is transmitted from the second dimming part 2 to the outside of the space 3 (i.e., the human eye side), thus realizing the single-sided display of the image.

[0058] In another specific embodiment of the present invention, such as Figure 9 As shown, a first dimming unit 1 and a second dimming unit 2 are spaced apart. The first dimming unit 1 includes a first transparent support layer 101 and a first dimming layer 102 stacked together. The first transparent support layer 101 and the first dimming layer 102 are connected by a first adhesive layer 103. The second dimming unit 2 includes a second transparent support layer 201 and a second dimming layer 202 stacked together. The second transparent support layer 201 and the second dimming layer 202 are connected by a second adhesive layer 203. An interval space 3 is formed between the first dimming layer 102 and the second dimming layer 202. A support portion 5 is sealed between the edge of the first dimming layer 102 and the edge of the second dimming layer 202. A notch is provided on the first dimming layer 102 near its edge to form a light-passing hole 6 on the first dimming unit 1. A light-transmitting portion 7 is provided on the outer surface of the first transparent support layer 101 and directly opposite the light-passing hole 6. A light source 4 is fixedly disposed on the light-transmitting portion 7. In this embodiment, the light emitted by the light source 4 penetrates the light-transmitting part 7 and directly enters the space between the two dimming parts 3, illuminating the second dimming part 2. This improves the utilization rate of light and ensures that the light can undergo more reflections within the space between the first dimming part 1 and the second dimming part 2, thereby improving the image display effect. Both the first transparent support layer 101 and the second transparent support layer 201 are transparent layers (such as colorless transparent layers, colored transparent layers, or multicolored transparent layers), and they do not affect the transmission of light. The first transparent support layer 101 and the second transparent support layer 201 can be made of, but are not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass, or transparent plastic.

[0059] In an optional embodiment of the present invention, the first dimming unit 1 and / or the second dimming unit 2 may also be a multilayer composite structure. The first dimming unit 1 includes a transparent first conductive support layer 104 and a second conductive support layer 105, which are stacked together. An electrolyte layer functional layer 106 is disposed between the first conductive support layer 104 and the second conductive support layer 105. The edges of the first conductive support layer 104 and the second conductive support layer 105 are sealed by an adhesive portion 107, thereby sandwiching the electrolyte layer functional layer 106 between the first conductive support layer 104 and the second conductive support layer 105. Similarly, the second dimming unit 2 includes a transparent third conductive support layer (not shown) and a fourth conductive support layer (not shown), which are stacked together. An electrolyte layer functional layer is disposed between the third conductive support layer and the fourth conductive support layer, and the edges of the third conductive support layer and the fourth conductive support layer are sealed by an adhesive portion, thereby sandwiching the electrolyte layer functional layer between the third conductive support layer and the fourth conductive support layer. During use, by energizing the electrolyte layer functional layer 106, the visible light reflectivity of the electrolyte layer functional layer 106 is changed, thereby switching the first dimming unit 1 between a state of total reflection of light and a state of semi-transmission and semi-reflection of light, and / or switching the second dimming unit 2 between a state of total reflection of light and a state of semi-transmission and semi-reflection of light.

[0060] In this embodiment, the functional layer 106 can be an electrolyte layer. Specifically, the functional layer 106 can be prepared using the technology described in application number 202311523433.0, entitled "A Display Device Based on Electroluminescent Technology and Its Preparation Method," to achieve adjustment of the visible light reflectivity of the first dimming unit 1 and / or the second dimming unit 2.

[0061] In one specific embodiment of the present invention, the functional layer 106 can switch between a state of total reflection of light and a state of semi-transmission and semi-reflection of light to meet the adjustment of different depth effects of image display; in addition, according to actual needs, the functional layer 106 can also be adjusted to a visible light transmittance greater than 90% (that is, to make the first dimming part 1 and the second dimming part 2 transparent respectively), thereby realizing the effect of panoramic glass so that passengers inside the vehicle can see the situation outside the vehicle.

[0062] In one specific embodiment of the present invention, such as Figure 10As shown, a first dimming unit 1 and a second dimming unit 2 are spaced apart. The first dimming unit 1 includes a transparent first conductive support layer 104 and a second conductive support layer 105. The first conductive support layer 104 and the second conductive support layer 105 are stacked. An electrolyte layer functional layer 106 is disposed between the first conductive support layer 104 and the second conductive support layer 105. The edges of the first conductive support layer 104 and the second conductive support layer 105 are sealed by an adhesive part 107, thereby sandwiching the electrolyte layer functional layer 106 between the first conductive support layer 104 and the second conductive support layer 105. The second dimming unit 2 can be a single layer of semi-transparent and semi-reflective glass or semi-transparent and semi-reflective plastic. An interval space 3 is formed between the first conductive support layer 104 and the second dimming unit 2. A support part 5 is sealed between the edge of the first conductive support layer 104 and the edge of the second dimming unit 2. The light source 4 is fixedly disposed on the support part 5. In this embodiment, the material used for the second dimming unit 2 can be laminated glass, tempered glass, or transparent plastic (i.e., the material of the second dimming unit 2 is, but is not limited to, soda-lime glass, quartz glass, borosilicate glass, aluminosilicate glass, or transparent plastic). Of course, in some other embodiments, the visible light reflectance can also be adjusted by coating (coating thickness of 100-500nm), laminating (film thickness less than or equal to 1mm), setting a coating layer, or laminating a film on the transparent material, so as to ensure that the visible light reflectance of the second dimming unit 2 is between 30% and 80%. In actual use, when the electrolyte layer functional layer 106 is powered on, it can be adjusted from a transparent state to a reflective state; when the electrolyte layer functional layer 106 is powered off, it can change from a reflective state to a transparent state. Thus, by changing the visible light transmittance of the electrolyte layer functional layer 106, the visible light reflectance of the first dimming unit 1 can be adjusted within the range of 10%-90%, thereby cooperating with the light source 4 to achieve the effects of dimming and displaying abyss atmosphere patterns.

[0063] In an optional embodiment of the present invention, such as Figure 12 As shown, a pattern layer 9 is provided on the first dimming unit 1 and / or the second dimming unit 2. A preset pattern (such as a logo or cartoon pattern) is formed on the first dimming unit 1 and / or the second dimming unit 2 to achieve a clear display effect of the pattern. The pattern layer 9 can be a printed ink layer formed on the first dimming unit 1 and / or the second dimming unit 2. The printed ink layer can be, but is not limited to, a transparent ink printing layer. When a transparent ink printing layer is used, the pattern is not displayed when the light source 4 is not turned on; the preset pattern is clearly displayed when the light source 4 is turned on. Of course, a regular ink printing layer can also be used. When a regular ink printing layer is used, the preset pattern can be displayed whether the light source 4 is turned on or off.

[0064] The features and advantages of the abyss ambient light structure of this invention are: 1. In this abyss ambient light structure, by setting a first dimming part 1 that can reflect light and a second dimming part 2 that can simultaneously reflect and transmit light, at least part of the light emitted by the light source 4 can be reflected multiple times in the space 3 between the second dimming part 2 and the first dimming part 1. Each time the light reflected from the first dimming part 1 to the second dimming part 2, a portion of the light can be transmitted from the second dimming part 2 to the outside of the space, thereby displaying a three-dimensional image on the human eye side, effectively enhancing the product's technological feel and atmosphere creation capabilities, and helping to improve the visual experience and emotional value of passengers.

[0065] Second, in the structure of this abyss ambient light, the first dimming unit 1, the second dimming unit 2 and the directional light guide structure 8 work together to achieve directional emission and transmission of light within the space 3, so that the light forms a uniform and soft diffuse reflection between the first dimming unit 1 and the second dimming unit 2, which can effectively improve the utilization rate of light. This reduces the width of the space 3 between the first dimming unit 1 and the second dimming unit 2 (i.e., the two pieces of glass), realizing the overall thin and light design of the product, making the abyss ambient light structure more compact and exquisite.

[0066] Third, in the structure of this abyss ambient light, the light source 4 can be set outside the partition space 3, that is, the light source 4 is completely external, so that the width of the partition space 3 is not limited due to providing installation space for the light source 4 (compared to the traditional partition between two pieces of glass, the width can be reduced by several millimeters), which realizes the slim and lightweight design of the product, effectively enhances the practicality of the product, and the external placement of the light source 4 makes it easier to disassemble and install.

[0067] IV. In this abyss-themed ambient light structure, the independent setting and external structure of the light source 4 facilitates easy maintenance and replacement, and reduces costs. If a single LED or driver circuit in the light source 4 is damaged, it is not necessary to disassemble or replace a large area of ​​glass; only the light source 4 needs to be inspected or replaced, greatly simplifying the maintenance process for the light source 4. If it is necessary to change the color or brightness of the ambient light, only the light source 4 needs to be replaced, facilitating product upgrades. Through the independent setting and external structure of the light source 4, the replacement and downtime caused by partial failures of the light source 4 can be effectively shortened, reducing costs.

[0068] V. In this abyss ambient light structure, by superimposing a dimming layer on the first dimming unit 1 and / or the second dimming unit 2, not only can the visible light transmittance and visible light reflectance of the abyss ambient light structure be adjusted to meet various display functions such as panoramic display, panoramic occlusion, or different light transmittance, but also the single-sided or double-sided display effect of the image can be achieved according to actual needs; in addition, an ink printing layer can be superimposed according to actual needs to meet the needs of displaying special patterns, thereby improving the practicality and atmosphere creation capabilities of the product.

[0069] Implementation Method 2

[0070] The present invention provides a vehicle window having the aforementioned abyss ambient light structure.

[0071] In this invention, the window can be, but is not limited to, the vehicle's sunroof. Of course, it can also be a window in other locations on the vehicle.

[0072] Compared to existing vehicle sunroofs, which can only display flat images (typically fixed flat patterns like starry skies) and lack a sense of depth and dynamic change, the windows in this invention with their abyss-like ambient lighting structure can display images with a three-dimensional sense of depth. This gives the images seen from the driver's side a unique and profound visual effect, enhancing the atmosphere of the vehicle's interior and the interaction between the driver and passengers, creating a sense of "extension" in the space. When passengers see the images displayed on the windows, they are not seeing a glowing point or a flat image, but rather an image with a three-dimensional sense of depth, thus reducing the feeling of oppression that the interior environment can bring to passengers.

[0073] The vehicle window of the present invention has the same features and advantages as the aforementioned abyss ambient light structure, which will not be repeated here.
