Description

Technical Field

[0001] This invention belongs to the field of automotive lighting technology, specifically relating to an automotive lighting system and its control method. Background Technology

[0002] Automotive lighting technology has evolved from "safety lighting" to "regular light pattern control," and then to "information projection interaction." Current mainstream technologies include matrix LED, Micro-LED, and DLP digital light processing, which can achieve intelligent functions such as adaptive high beams, dynamic turn signals, and projected warning signs. These technologies have achieved significant results in improving driving safety and enhancing driver interaction. Essentially, these technologies still belong to the "pixel-driven" optical expression method, that is, by controlling the switching state of discrete light-emitting units or micromirror arrays, an image composed of a pixel matrix is ​​formed on the projection surface. This technical solution has advantages in expressing regular geometric shapes, text labels, and simple icons, but it suffers from insufficient adaptability when facing the needs of highly artistic, highly continuous, and richly layered complex lines and shapes (such as traditional cultural elements like landscape paintings and calligraphy).

[0003] Taking landscape painting as an example, its core aesthetic characteristics lie in "vibrant spirit," "continuous meaning despite broken brushstrokes," and "natural texturing techniques." Its lines possess continuity, randomness, rhythm, and emotional expressiveness. These characteristics require optical systems to possess the following capabilities: sub-pixel-level continuous light intensity transition capability to simulate variations in ink density; a non-discrete light guiding mechanism to achieve visual coherence of "continuous meaning despite broken brushstrokes"; and the ability to reconstruct light and shadow at three-dimensional levels to present the texture and depth of mountains, rocks, and water ripples. However, existing technologies such as DLP and Micro-LED are based on discrete pixel arrays, whose light intensity distribution exhibits abrupt changes at pixel boundaries, making true continuous light intensity transition impossible. Even if a continuous effect is approximated through high-density pixel arrays, the required pixel density (thousands per square millimeter) far exceeds the physical limits of current automotive lighting optical systems and would impose an unbearable engineering burden in terms of heat dissipation, driving, and cost. Therefore, existing technologies face a fundamental technical obstacle between optical expression methods and artistic aesthetic needs, rather than a simple lack of parameters. Specifically, this manifests in the following shortcomings: First, in terms of expression: the lines are broken and lack continuity of spirit. Traditional brushstroke techniques in landscape painting, such as "cunfa" and "dianmo," possess a strong dynamic randomness, requiring lines to appear visually continuous. However, pixel projection systems exhibit a noticeable sense of dispersion at pixel boundaries, failing to simulate the artistic effect of "broken brushstrokes but continuous meaning." Even with high-resolution Micro-LEDs, the lines still appear jagged or stepped, lacking the natural flow of traditional ink painting.

[0004] Secondly, the layering dimension: Two-dimensional planar expression lacks a sense of three-dimensionality and the combination of reality and illusion. Existing technologies mostly use planar projection or screen imaging, resulting in a "virtual" effect that fails to achieve the three-dimensional layering of "near real, far blurred" and "layered mountains" found in landscape paintings. In particular, it cannot present a simple appearance (such as a "gray screen" effect) in a static, unlit state, but when lit, it displays dynamic visual effects like three-dimensional landscapes and starry sky reflections, lacking aesthetic depth and user-friendly appeal.

[0005] Third, the integration dimension: difficulty in coordinating the expression of multiple elements. Some existing patents (such as CN208779374U and CN222377920U) have achieved static expression of starry sky or dazzling effects, but their optical structures are only single-layer point reflections, which cannot simultaneously present the fusion effect of starry sky background and landscape outline in the same system, let alone achieve dynamic layer switching (such as independent control of low-brightness background mode and high-brightness outline mode). This limits the comprehensive expressiveness of vehicle lights in terms of cultural expression and personalized interaction.

[0006] Fourth, the technological dimension: complex textures are difficult to mass-produce. The lines in landscape paintings have extremely fine widths (down to less than 0.1mm) and rich three-dimensional forms (such as mountain ridges and undulating water ripples). Existing processes such as injection molding, etching, and laser engraving generally suffer from problems like difficulty in demolding, texture collapse, and microstructure distortion when dealing with such complex textures, making it difficult to achieve high consistency and high yield in mass production. This further hinders the transition of artistic car lights from conceptual design to mass production.

[0007] In conclusion, existing automotive lighting technologies still have many shortcomings in achieving complex artistic lines, three-dimensional layering, the integration of real and virtual elements, and the fusion of multiple elements. Therefore, there is a need to design automotive lighting systems that can break through traditional optical expression methods and achieve high-precision reproduction of artistic lines, in order to meet the higher demands of automotive lighting in terms of cultural expression, aesthetic enhancement, and personalized interaction. Summary of the Invention

[0008] The primary objective of this invention is to provide an automotive lighting system that addresses the technical problem of achieving lighting effects that incorporate continuous artistic lines, three-dimensional layering, and multi-element fusion.

[0009] The second objective of this invention is to provide a control method for an automotive lighting system, in order to solve the technical problem of achieving a lighting effect that enables the automotive lighting system to produce continuous artistic lines, three-dimensional layering, and multi-element fusion.

[0010] The vehicle lighting system of the present invention is implemented as follows: A vehicle lighting system includes at least: an interior lens assembly and a first light source assembly disposed on the light-incident side of the interior lens assembly; the interior lens assembly includes a first interior lens, a second interior lens, and at least one third interior lens arranged sequentially along the light-out direction; wherein... The first inner lens has an optical pattern on its light-emitting surface, which is used to initially refract and disperse the light emitted by the light source assembly; the second inner lens is a micro-perforated transmission inner lens, which is used to form a background pattern when lit; each layer of the third inner lens has complex lines and / or surface structures for presenting the main artistic pattern. The first and second internal lenses are inclined to form a flared light outlet between their lower sides; each layer of the third internal lens includes a lens body located on the side of the second internal lens facing away from the first internal lens and a lens extension located on the side of the flared light outlet; and The vehicle lighting system also includes a second light source assembly located below the first light source assembly and behind the lens extension of each layer of the third endoscope.

[0011] In optional embodiments of the invention, the complex lines and / or surface structures of each layer of the third endoscope are designed on the lens body; and The complex lines and / or surface structures are also designed with micro-step structures.

[0012] In an optional embodiment of the invention, the top of the lens body of each third inner lens is lower than the top of the second inner lens, so that the design of all third inner lenses does not create overall obstruction of the background pattern formed when the second inner lens is lit.

[0013] In an optional embodiment of the invention, the vehicle lighting system includes two layers of the third interior mirror; and The tops of the two layers of the third endoscope have a staggered distribution structure.

[0014] In an optional embodiment of the present invention, the endoscope assembly further includes a fourth endoscope located on the light-emitting side of at least one third endoscope. The fourth internal lens includes a lens body located on the side of the third internal lens body facing away from the second internal lens and a lens extension located on the side of the horn-shaped light outlet.

[0015] In an optional embodiment of the present invention, the included angle between the lens extension and the flared light exit aperture of each of the third inner lens layers is 90°±45°; and The angle between the lens extension of the fourth internal lens and the horn-shaped light outlet is 90°±45°.

[0016] In optional embodiments of the present invention, the fourth endoscope is only suitable for transmitting light; or the endoscope body of the fourth endoscope is provided with patterns for secondary modification of light.

[0017] In an optional embodiment of the invention, the fourth endoscope is formed with a fully transparent open window suitable for exposing the complex lines and / or surface structures of each layer of the third endoscope; or The fourth inner lens is suitable for covering the complex lines and / or surface structures of the microtransparent window mirror body of each layer of the third inner lens, and the light-incident surface of the microtransparent window mirror body is provided with a microtransparent coating.

[0018] The control method based on the vehicle lighting system of the present invention is implemented as follows: A control method based on the aforementioned vehicle lighting system includes the following steps: The first light source component is controlled to light up in the first brightness mode, so that the light is guided by the optical structure of the inner lens component, and the background pattern and the main artistic pattern are lit up at the same brightness. The second light source component is controlled to light up in the second brightness mode, so that the light is guided by the optical structure of the inner lens component, making the brightness of the main artistic pattern higher than that of the background pattern, so as to present a lighting effect with contrast between light and dark.

[0019] In optional embodiments of the present invention, the first brightness mode and the second brightness mode are independently controlled or switched sequentially to achieve dynamic layer changes in the artistic pattern.

[0020] The beneficial effects of this invention are that the vehicle lighting system and its control method provided by this invention, firstly, through the collaborative design of multiple inner mirrors (the optical pattern of the first inner mirror, the background pattern formed when the second inner mirror is lit, and the landscape outline of multiple third inner mirrors), achieves multi-level optical expression from background to foreground, from low brightness to high brightness, and from virtual to real. Thus, in the field of vehicle lighting opticals, it realizes the continuous and non-discrete expression of complex artistic lines, breaks through the limitations of the "pixel-driven" optical structure, and achieves the artistic effect of "broken strokes but continuous meaning" and "vivid rhythm".

[0021] Furthermore, the micro-transparent design of the fourth inner lens enables the switching between the simple "gray screen" appearance when the screen is not lit and the "window reflection" effect of the internal three-dimensional pattern when the screen is lit, enhancing the user's desire for exploration and the fun.

[0022] In addition, by using processes such as split-layer design, arc transition, micro-step structure optimization, and high-precision conformal cooling mold, the demolding and forming problems of complex textures have been solved, ensuring a high yield rate for mass production.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: In this embodiment, the directional concepts “top,” “bottom,” “lower,” and “upper” are all combined with the specific viewing angle of the vehicle lighting system. “Front” and “rear” are combined with the direction of light emission. The direction in which the light is emitted is “front,” and the opposite is “rear.”

[0030] Please see Figures 1 to 11 As shown, this embodiment provides a vehicle lighting system that can be applied to lighting scenarios in the interior or exterior of a car. This embodiment does not make absolute limitations on the specific lighting scenarios.

[0031] Specifically, the vehicle lighting system of this embodiment includes at least: an interior mirror assembly and a first light source assembly 5 disposed on the light-incident side of the interior mirror assembly; the interior mirror assembly includes a first interior mirror 1, a second interior mirror 2 and at least one third interior mirror 3 arranged sequentially along the light-out direction.

[0032] The light-emitting surface of the first inner lens 1 is provided with optical patterns 11, such as, but not limited to, irregular facets resembling diamond faces, to initially refract and disperse the light emitted by the light source component. When the light passes through these optical patterns 11, it undergoes multi-directional refraction and dispersion, forming a basic light effect of brilliance or uniform scattering. A curved surface structure 12 may also be provided in a localized area of ​​the light-emitting surface of the first inner lens 1 to concentrate some of the light and project it to a specific point, creating a high-brightness effect at the inflection point.

[0033] The second internal lens 2 is a microporous transmission internal lens with multiple light-transmitting holes 21. The shape of the light-transmitting holes 21 can be regular, such as a circle, triangle, or pentagram, or it can be irregular, such as, but not limited to, a cloud shape. The different shapes of the light-transmitting holes 21 are used to form a background pattern when the second internal lens 2 is lit (for example, when a regular shape is used, it can simulate the visual effect of stars in the night sky K1).

[0034] The first internal lens 1 and the second internal lens 2 are inclined to form a horn-shaped light outlet 6 between their lower sides. The design of the horn-shaped light outlet 6 allows light from the first light source assembly 5 to enter the subsequent internal lens at a large angle, achieving uniform background illumination.

[0035] Each layer of the third inner lens 3 is a transparent inner lens (made of PC or PMMA), and each layer of the third inner lens 3 includes a lens body 71 located on the side of the second inner lens 2 facing away from the first inner lens 1 and a lens extension 72 located on the side of the horn-shaped light outlet 6. It should be noted that the opening angle of the horn-shaped light outlet 6 is designed to be 60°±10°, so that the light from the first light source assembly 5 can enter the lens extension 72 of the third inner lens 3 at a large angle range.

[0036] Based on the above structure, each layer of the third inner mirror 3 has a mirror body 71 with complex lines and / or surface structures 31 for presenting the main artistic pattern, such as the outline of mountain ridges, water ripples, and tree branches in a landscape painting. The complex lines and / or surface structures 31 here can be formed by one or more of the following processes: mold texture, laser etching, sandblasting, chrome plating, hot stamping, laser engraving, or CNC machining.

[0037] It is also necessary to explain here that the top of the mirror body 71 of each third inner lens 3 is lower than the top of the second inner lens 2, so that the design of all the third inner lenses 3 will not completely block the background pattern formed when the second inner lens 2 is lit. This ensures that the background pattern formed when the second inner lens 2 is lit can not only be seen through the third inner lens 3 in a faint way, but also be partially seen directly, thereby achieving a presentation effect that combines the real and the virtual.

[0038] Based on the above, for the vehicle lighting system of this embodiment, in one implementation, it includes only one layer of third inner mirror 3; in another implementation, it includes two layers of third inner mirror 3, with the lines and / or patterns of the two third inner mirror 3 complementing and overlapping each other to form a richer visual effect. In this case, it is necessary to explain that the tops of the two layers of third inner mirror 3 are arranged in a staggered structure, which, together with the background pattern formed by the lit second inner mirror 2, forms a "layered mountain" layout, enhancing the sense of three-dimensionality and depth of field, and better simulating the layered effect K2 of distant mountains and nearby water in a landscape painting.

[0039] Based on the above structure, in an optional implementation, the vehicle lighting system used in this embodiment further includes a fourth inner mirror 4 located on the light-emitting side of at least one third inner mirror. It should be noted that, regarding the fourth inner mirror 4, in the first optional implementation, it may only be suitable for transmitting light, serving as a light-transmitting window so that the observer can directly see the complex patterns on the inner third inner mirror 3; in the second optional implementation, the fourth inner mirror 4 is provided with pattern textures 41 for secondary light modification, further enriching the visual effect.

[0040] Furthermore, it is necessary to explain that, in one specific optional implementation, the fourth inner mirror 4 forms a fully transparent open window 43 suitable for revealing the complex lines and / or surface structures 31 of each layer of the third inner mirror 3, creating an "open window" display effect; in another specific optional implementation, the fourth inner mirror 4 is suitable for covering the micro-transparent window mirror body 42 of the complex lines and / or surface structures 31 of each layer of the third inner mirror 3, and the light-receiving surface of the micro-transparent window mirror body 42 is provided with a micro-transparent coating (a slightly translucent chrome plating layer or other equivalent chrome-plated laser engraving). Generally, based on this design, it presents a simple effect when statically unlit, and when lit, the internal patterns appear through the micro-transparent coating, creating a dreamlike effect of illusion within reality and reality within illusion. More specifically, the back of the fourth inner mirror 4 in this design is provided with a chrome-plated micro-transparent layer. When statically unlit, the fourth inner mirror 4 presents a simple and elegant mirror appearance. When the light source is turned on, the light shines through the chrome-plated micro-transparent layer, and the three-dimensional landscape pattern inside gradually appears, forming a "window reflection" effect—real within the virtual, and virtual within the real, which has a sense of exploration and artistic appeal.

[0041] Next, it should be noted that the fourth inner lens 4 includes a lens body 75 located on the side of the third inner lens 3 facing away from the second inner lens 3, and a lens extension 76 located on the side of the flared light outlet 6. Based on this, a pattern 41 for secondary light modification can be provided on the lens body 75 of the fourth inner lens 4. A light-blocking decorative frame 93 corresponding to the lens extension 76 is also provided on the side of the fourth inner lens 4 facing away from the third inner lens 3. Therefore, the angle formed between the lens extension 72 of each third inner lens 3 and the flared light outlet 6 is 90°±45°, and the angle formed between the lens body 75 and the lens extension 76 of the fourth inner lens 4 is 90°±45°, thereby achieving better light coupling efficiency. In this embodiment, the angle is designed to be approximately 85°.

[0042] Based on the above structure, in one specific optional implementation, for each layer of the third inner lens 3 and the fourth inner lens 4, optical textures 78 can be designed on both sides of their lens extensions 72 and 76 to achieve a uniform layered light guiding effect. A nanoscale optical diffusion coating can also be embedded in the complex lines and / or surface structures 31 of each layer of the third inner lens 3 to uniformly diffuse light along the etching path, achieving a high-brightness outline effect.

[0043] Based on the above, the vehicle lighting system of this embodiment further includes a second light source assembly 10 located below the first light source assembly 5 and behind the mirror extension 72 of each third inner lens 3 and the mirror extension 76 of each fourth inner lens 4. Each mirror extension 72 of the third inner lens 3 and the mirror extension 76 of the fourth inner lens 4 is provided with an optical surface 74 facing the second light source assembly 10. Therefore, for the light emitted from the second light source assembly 10, through the scattering effect of the optical surface 74 of the adjacent third inner lens 3, and the refraction and total internal reflection effect of the optical texture 78 of the mirror extension 72, a bright background light and incident light from the third inner lens 3 relatively far from the second light source assembly 10 are formed by the optical texture 78. The first light source component 5 provides low-brightness background lighting, the light of which, after being guided by the inner lens component, forms the base brightness of the artistic pattern; and the second light source component 10 provides high-brightness contour lighting, the light of which, after being guided by the inner lens component, forms a high-brightness expression of lines or contours in the artistic pattern, so that complex lines and shapes present a clear and bright contour effect when needed. Both the first light source component 5 and the second light source component 10 generally include a PCB board and LED light-emitting particles integrated on the PCB board.

[0044] Understandably, the vehicle lighting system of this embodiment also includes a lampshade 91 and a bracket 92 used in conjunction with mature technologies, and the lampshade 91 and the bracket 92 cooperate to form a cavity for accommodating the first light source assembly 5, the second light source assembly 10 and the internal lens assembly.

[0045] Next, it should be noted that there is an arc-shaped transition 73 between the lens extension 72 and the lens body 71 of each third inner lens 3; and there is an arc-shaped transition 73 between the lens extension 76 and the lens body 75 of the fourth inner lens 4. This arc-shaped transition 73 design facilitates the smooth guidance of light, reduces light loss, and also facilitates injection molding and demolding.

[0046] Based on the above structure, in one optional implementation, the complex lines and / or surface structures 31 on each layer of the third inner lens 3 are designed on the lens body 71; and the complex lines and / or surface structures 31 are also designed with micro-step structures 8. These micro-step structures 8 can be, for example, raised ridges designed on the outer surface of a three-dimensional landscape pattern corresponding to each contour line. The height of the micro-step structure 8 is 0.05 mm to 1 mm, used to generate Fresnel diffraction or edge lighting effects when light passes through it, forming bright contour lines and simulating the visual continuity of "broken strokes but connected meaning." More specifically, when light propagates inside the third inner lens 3 to the micro-step structure 8, because the micro-step structure 8 is a clearly discontinuous structure, Fresnel diffraction occurs when the light passes through the abrupt boundary, forming an edge lighting effect. Simultaneously, the residual microburrs and roughness at the micro-step structure 8 further enhance scattering, forming bright lines. Furthermore, the abrupt change in incident angle at the eight points of the micro-step structure easily creates specular reflection. When the detection / illumination angle is precisely aligned with the step, the observation direction is exactly on the path of the reflected light. The light at point eight of the micro-step structure is concentrated and refracted / diffracted, while the reflected light from other inclined surfaces is deflected, making point eight of the micro-step structure appear exceptionally bright. This ingenious design allows every outline in the three-dimensional landscape pattern to be clearly identified, achieving visual continuity of "broken brushstrokes but connected meaning," without relying on high-density discrete pixels.

[0047] Finally, it should be noted that a medium can be filled between the second inner lens 2, the third inner lens 3, and the fourth inner lens 4. This medium can be either air or UV-resistant optical adhesive. Based on this design, the propagation characteristics of light at the interlayer interface can be adjusted by controlling the refractive index of the medium between these three inner lenses. When the filling medium is air, the refractive index of air (1.0) differs significantly from that of transparent materials (approximately 1.5), resulting in slightly lower light energy utilization. When the filling medium is UV-resistant optical adhesive (typically with a refractive index of 1.45–1.55), it is filled through dispensing or potting processes and then cured. The refractive index matching eliminates interface reflection, resulting in high light energy utilization and improved overall brightness. In practical applications, air can be used when a strong technological feel is desired; while UV-resistant optical adhesive can be used when a softer, more diffused effect with high overall brightness is desired.

[0048] In summary, the automotive lighting system of this invention, through multi-layered internal mirror collaborative design and controllable optical path guidance, achieves continuous, three-dimensional, and combined real-virtual optical reproduction of traditional artworks such as landscape paintings in the field of automotive lighting. It solves the problem of existing technologies being unable to express complex artistic lines, overcomes the technical barriers of traditional automotive lighting in expressing complex artistic lines, and realizes the optical reproduction of delicate lines in artworks such as landscape paintings. This system has a reasonable structural design, high optical efficiency, and feasible manufacturing process, meeting the requirements of mass production. It can be widely used in automotive front position lights, rear position lights, daytime running lights, ambient lighting, and other fields, demonstrating good industrial applicability.

[0049] Example 2: Based on the vehicle lighting system of Example 1, this example provides a control method for a vehicle lighting system, including the following steps: The first light source component 5 is controlled to light up in the first brightness mode, so that the light is guided by the optical structure of the inner lens component and the background pattern and the main artistic pattern are lit up at the same brightness (low brightness mode); the second light source component 10 is controlled to light up in the second brightness mode, so that the brightness of the main artistic pattern is higher than that of the background pattern, so as to present a lighting effect with contrasting light and dark (high brightness mode).

[0050] Based on the above, it is necessary to explain that the first brightness mode and the second brightness mode are controlled independently or switched sequentially to achieve dynamic layer changes in the artistic pattern.

[0051] In summary, the specific implementation principle of automotive lighting systems is as follows: When the first light source component 5 is lit, the light is dispersed by the diamond pattern of the first inner lens 1, and part of it enters the mirror extension 72 of the third inner lens 3 through the trumpet-shaped light outlet 6 and is then guided into the mirror body 71. At this time, the second inner lens 2 is lit to form a background pattern. At the same time, when the light propagates in the mirror body 71, some of the light rays undergo Fresnel diffraction and edge scattering of the complex lines and / or the micro-step structure 8 of the surface structure 31, forming faint bright lines of the outline; some light rays are evenly emitted from the optical texture surface at the top of the mirror body 71, forming the brightness of the main artistic pattern.

[0052] When the second light source component 10 is lit, the light shines directly into the rear of the mirror extension 72 of the third inner mirror 3 and the fourth inner mirror 4. After being guided by the arc transition 73, the light forms a stronger high-brightness outline on the complex lines and / or surface structure 31 of the main artistic pattern, making the brightness of the main artistic pattern higher than that of the background pattern. In this case, for the overall vehicle lighting system, a lighting effect with different brightness at the front and rear is formed (the background pattern at the rear is "dark" and the main artistic pattern at the front is "bright").

[0053] Based on the above, it should also be noted that the first light source component 5 and the second light source component 10 can also be lit simultaneously.

[0054] The following examples illustrate the different application modes of automobiles, including: static display mode, dynamic breathing mode, welcome mode, and driving mode. The first mode is a static display mode, in which the first light source component 5 is controlled to be lit at a constant low brightness, so that the background pattern and the main artistic pattern are lit at the same brightness; at the same time, the second light source component 10 is not lit or is only slightly lit, so that the outline lines present a soft effect.

[0055] The second type is the dynamic breathing mode, which controls the first light source component 5 to light up with periodically changing brightness, while the second light source component 10 changes in the opposite phase to achieve the "breathing" effect of the landscape pattern from dark to light and from light to dark, simulating the artistic conception of ink painting.

[0056] The third type is the welcoming mode. First, the second light source component 10 is controlled to quickly illuminate the outline lines in a high-brightness mode. Then, the first light source component 5 is controlled to gradually brighten. Finally, the second light source component 10 is gradually dimmed, forming a writing effect of "first outlining the outline, then filling in the ink".

[0057] The fourth driving mode controls the first light source component 5 to illuminate at a low brightness, ensuring that the landscape pattern serves as a soft expression for the position lights and avoiding high-brightness outlines that would distract the driver.

[0058] The above modes can be automatically switched according to user settings or vehicle status.

[0059] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0060] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0061] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0062] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.

[0063] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.
