Description

【Technical Field】 【0001】 The subject matter of the embodiments described herein generally relates to glass articles, and more particularly to coated glass articles that optimize the transmission of infrared light and the reflection of visible light. 【Background Art】 【0002】 Conventional glass articles typically comprise either monolithic glass or laminated glazing. Monolithic glass products consist of a single sheet of glass and can be enhanced with additional processes to provide insulation, design improvements, and increased strength. Monolithic glass articles can typically be used for building skylights and windows. In contrast, laminated glazing glass articles typically comprise two glass sheets joined together by an adhesive interlayer. The adhesive interlayer can be manufactured from certain materials such as polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), or thermoplastic polyurethane (TPU), such that when the laminated glazing product breaks, the glass sheets are fragmented into smaller and less dangerous pieces. Such beneficial features enable the use of laminated glazing articles in applications where humans may be exposed, such as automotive windshields and windows. 【0003】 The ability to control the light transmission and light reflection of glass articles also makes them suitable for certain applications where a certain amount of light and / or thermal radiation passing through the glass article and the light reflection of the glass article are desirable. One such application is the windshield used in automobiles. 【0004】 Commercial and passenger vehicles are designed to use technologies such as head-up display (HUD) systems and sensors to improve safety, road capacity, and fuel efficiency while reducing pollution, driver stress, and operating costs. HUD systems display information projected onto a glass article (e.g., the windshield of a vehicle), reflect it towards the driver or observer, and provide relevant information to the driver of the vehicle without diverting their eyes from the forward field of view of the vehicle. 【0005】 These vehicles are designed to detect their surroundings using a variety of sensors, including but not limited to optical sensors such as radar, LIDAR (light detection and ranging), GPS, odometry, and computer vision. Typically, optical sensors are mounted on the inner surface of glass articles, providing suitable positioning for geometric distance estimation, enhanced display of road and traffic conditions, and a controlled environment for operating the optical sensors. However, because optical sensors require increased infrared transmittance, they are not entirely compatible with the configurations of conventional glass articles. 【0006】 Currently, conventional glass articles used as vehicle windshields either do not adequately provide a sufficient amount of infrared light with sufficient intensity to pass through the windshield for the proper operation and performance of LIDAR sensors, or, when conventional glass articles are treated with anti-reflective coatings or the like to increase infrared light transmittance for the proper operation and performance of LIDAR sensors, the visible light reflectivity of the glass product is insufficient for the proper operation and performance of HUD systems. 【0007】 Therefore, it would be desirable to manufacture glass articles that include at least one coating that optimizes infrared light transmission for the proper operation and performance of optical sensors, while maintaining sufficient visible light reflection for the proper operation and performance of the HUD system. [Overview of the project] 【0008】 Consistent with this disclosure, we have discovered a glass article comprising at least one coating that optimizes infrared light transmission for the proper operation and performance of an optical sensor while maintaining sufficient visible light reflectivity for the proper operation and performance of the HUD system. 【0009】 In one embodiment, the coated glass article comprises a first glass sheet, an anti-reflective layer disposed adjacent to at least a portion of the first glass sheet, and a visible light reflective layer disposed above at least a portion of the anti-reflective layer, wherein the visible light reflective layer has a refractive index of 1.6 or more and a thickness of 30 nm or less, and the coated glass article exhibits a light transmittance of at least 80% and a visible light reflectance of about 8% to 10% for at least one wavelength of infrared light. 【0010】 In a particular embodiment, the first glass sheet is manufactured from a glass material that generally has low light absorption and high light transmittance. 【0011】 In a particular embodiment, the first glass sheet is manufactured from a glass material having an iron content of less than 100 ppm, preferably 10 ppm or less. 【0012】 In a particular embodiment, a second glass sheet is further provided, and the first glass sheet and the second glass sheet are joined to each other by an adhesive layer. 【0013】 In a particular embodiment, the adhesive layer comprises at least one ply of at least one of the following: polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyvinyl chloride (PVC), polyurethane (PU), sound-absorbing modified PVB, and Uvekol® (liquid curable acrylic resin I). 【0014】 In a particular embodiment, the adhesive layer comprises a plurality of plies. 【0015】 In a particular embodiment, the adhesive layer includes a first ply made of PVB, a second ply made of polyethylene terephthalate (PET), and a third ply made of PVB. 【0016】 In a particular embodiment, the second glass sheet is manufactured from a glass material that generally has low light absorption and high light transmittance. 【0017】 In a particular embodiment, the glass material is manufactured from a glass material having an iron content of less than 100 ppm, preferably 10 ppm or less. 【0018】 In a particular embodiment, the coated glass article further includes at least one reflective layer, which may be a sunlight and / or infrared reflective layer. 【0019】 In a particular embodiment, at least one reflective layer is positioned adjacent to at least a portion of one of the first sheet and the second sheet. 【0020】 In a particular embodiment, at least one reflective layer is incorporated into a multilayer intermediate layer. 【0021】 In a particular embodiment, the glass article may include a plurality of reflective layers arranged adjacent to at least one of the first and second glass sheets and incorporated in a multilayer structure. 【0022】 In a particular embodiment, at least one reflective layer comprises a metallic material. 【0023】 In a particular embodiment, at least one reflective layer includes at least one void formed therein. 【0024】 In a particular embodiment, the anti-reflective layer is formed to cover at least a portion of at least one of the first sheet and the second sheet. 【0025】 In a particular embodiment, each of the first sheet and the second sheet includes a first main surface and a second main surface, and the anti-reflective layer is disposed adjacent to at least a portion of the second main surface of the second sheet. 【0026】 In a particular embodiment, the anti-reflective layer has a thickness of at least 80 nm. 【0027】 As an aspect of a specific embodiment, the anti-reflection layer has a thickness in the range of about 120 nm to about 200 nm.

[Modes for carrying out the invention] 【0057】 The following detailed description and accompanying drawings illustrate and illustrate various exemplary embodiments. The description and drawings are intended to enable those skilled in the art to create and use embodiments and are not intended to limit the scope of embodiments in any way. 【0058】 Figures 1-3 and 5 show glass articles 10, 10', and 10'' having a laminated structure, respectively. Figure 6 shows a glass article 10'''' having a monolithic structure. According to the subject matter of this disclosure, each of the glass articles 10, 10', 10'', and 10'''' may be planar. However, the glass articles 10, 10', 10'', and 10'''' may be curved, as shown in Figure 1, for use in rear windows, side windows, sunroofs, and moonroofs in the automotive industry, and especially in the case of windshields. The radius of curvature in at least one direction is preferably in the range of about 500 mm to about 20,000 mm, and more preferably in the range of about 1,000 mm to about 8,000 mm. 【0059】 Each of the glass articles 10, 10', 10'', and 10'''' may be configured for use with a head-up display (HUD) system 8, 8' (shown in Figure 1) and an optical sensor 11 (shown in Figures 2 and 3) in a vehicle (not shown). It should be understood that the HUD systems 8, 8' can be any HUD system 8, 8' as desired. Furthermore, each of the glass articles 10, 10', 10'', and 10'''' may be configured for use as a window in an architectural structure. However, it should be understood that the glass articles 10, 10', 10'', and 10'''' may be used in a variety of other applications where a specific visible light reflectance and infrared light transmittance through the glass articles 10, 10', 10'', and 10'''' are desired. It should be understood that the glass articles 10, 10', 10'', and 10'''' may be used in a variety of industrial, commercial, residential, and automotive applications. 【0060】 The glass articles 10, 10', 10'', 10''' of the subject disclosed herein may be positioned at rake angles in the range of about 50° to 70° from the vertical, and may have a light transmittance of 75% or less for two or more wavelengths in the range of about 750 nm to 1 mm (when measured with CIE light source A), and the external and internal visible light reflectances may each be in the range of about 7.0% to about 10.0%. Preferably, each of the glass articles 10, 10', 10'', 10'''' may be positioned at a rake angle of about 60° from the vertical, at least the first portion of the glass articles 10, 10', 10'', 10'''' may have a light transmittance of at least 94% (measured with CIE light source A) at a first wavelength of about 905 nm and a second wavelength of about 1550 nm, at least the second portion of the glass articles 10, 10', 10'', 10'''' may have substantially the same external and internal visible light reflectance as an uncoated glass article, preferably in the range of about 8% to about 9%, more preferably the external visible light reflectance may be about 8.6% and the internal visible light reflectance may be about 8.8%. 【0061】 Referring here to Figure 2, the shown glass article 10 is a laminated glazing according to one embodiment of the subject matter of the present invention. As shown, the glass article 10 may include a first sheet 12 and a second sheet 14 bonded to the first sheet 12 by an adhesive intermediate layer 16. The first and second sheets 12, 14 may be substantially transparent and transparent to visible light. Each of the first and second sheets 12, 14 may be manufactured from a generally low-absorption, high-transmittance glass material. In certain embodiments, the first and second sheets 12, 14 may be manufactured from any glass composition and may be manufactured using any glass manufacturing process. Preferably, each of the first and second sheets 12, 14 may be manufactured from a soda-lime silica material. Soda lime silica material may contain 70-75% (by weight) silicon dioxide (SiO2), 0-5% aluminum oxide (Al2O3), 10-15% sodium oxide (Na2O), 0-5% potassium oxide (K2O), 0-10% magnesium oxide (MgO), 5-15% calcium oxide (CaO), and 0-2% sulfur trioxide (SO3). However, it should be understood that the first and second sheets 12 and 14 may each contain other compositions, such as borosilicate material compositions. 【0062】 In certain embodiments, each of the first and second sheets 12, 14 may be manufactured from a generally low-iron glass material. Preferably, the first and second sheets 12, 14 may be manufactured from a glass material having an iron oxide (Fe2O3) content of about 100 ppm or less. More preferably, the iron oxide (Fe2O3) content in the first and second sheets 12, 14 may be about 10 ppm or less. Also, the transparency and / or absorption properties of the first and second sheets 12, 14 may differ among embodiments of the glass article 10. For example, the first and second sheets 12, 14 may be colored. Furthermore, the thickness of each of the first sheet 12 and the second sheet 14 may differ among embodiments of the glass article 10. In certain embodiments, the thickness of each of the first sheet 12 and the second sheet 14 may range from about 0.7 mm to about 12 mm. Preferably, each of the first and second sheets 12, 14 may have a thickness of about 2.2 mm. 【0063】 The first sheet 12 may have a first main surface 1 and a second main surface 2 on the opposite side. The second sheet 14 may have a first main surface 3 and a second main surface 4 on the opposite side. When the glass article 10 is used as a windshield of a vehicle, the main surface 1 faces the external environment (indicated by the sun 17) and the second main surface 4 faces the interior of the vehicle. Thus, the first sheet 12 is the "outer glass" of the windshield, and the second sheet 14 is the "inner glass" of the windshield. 【0064】 As shown in Figure 2, the adhesive interlayer 16 may be interposed between the first sheet 12 and the second sheet 14. Similar to the first sheet 12 and the second sheet 14, the transparency and / or absorption properties of the interlayer 16 may vary between embodiments of the glass article 10. For example, the adhesive interlayer 16 may be colored as needed. In one embodiment shown in Figure 2, the adhesive interlayer 16 may be a single layer positioned adjacent to the second main surface 2 of the first sheet 12 and the first main surface 3 of the second sheet 14. The single-layer adhesive interlayer 16 may be formed from polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyvinyl chloride (PVC), polyurethane (PU), sound-absorbing modified PVB, and / or liquid-curable acrylic resin (e.g., Uvekol (trademark registered)). The thickness of the single-layer adhesive interlayer 16 may range from about 0.3 mm to about 2.3 mm. Preferably, the single-layer adhesive intermediate layer 16 has a thickness in the range of about 0.3 mm to about 1.1 mm, and more preferably about 0.76 mm. More preferably, the glass sheets 12 and 14 of the glass article 10 may be manufactured from Pilkington Optiwhite®, which is commercially available from Pilkington Group Limited, and may be joined by the single-layer adhesive layer 16. In a preferred embodiment, each of the glass sheets 12 and 14 may be manufactured from Pilkington Optiwhite® having a thickness of about 2.2 mm, and the single-layer intermediate layer 16 may have a thickness of about 0.76 mm. 【0065】 In certain embodiments, the glass article 10 may further include at least one reflective layer 24. As shown in Figure 2, at least one reflective layer 24 may be located adjacent to the adhesive intermediate layer 16 on either the second main surface 2 of the first sheet 12 or the first main surface 3 of the second sheet 14. In certain embodiments, the glass article 10 may include a plurality of reflective layers 24 located adjacent to at least one of the first sheet 12 and the second sheet 14. For example, the glass article 10 may include one of the reflective layers 24 located adjacent to the second main surface 2 of the first sheet 12 and another of the reflective layers 24 located adjacent to the first main surface 3 of the second sheet 14. 【0066】 The at least one reflective layer 24 shown in the illustration reflects sunlight and / or infrared radiation. In certain embodiments, the at least one reflective layer 24 may be formed of, for example, a metallic material (e.g., silver), tin-doped indium oxide, lanthanum hexaboride, or other such suitable infrared reflective material. In certain embodiments, the at least one reflective layer 24 may be deposited by sputtering. Various other methods may be used to form the at least one reflective layer 24 as needed. The at least one reflective layer 24 may extend substantially over the entire surface of the first and second sheets 12, 14, but may also be formed to extend only over a portion of that surface. The periphery of the at least one reflective layer 24 may be offset from the periphery of the first and second sheets 12, 14 and / or the adhesive interlayer 16 to reduce corrosion and damage. The thickness of the at least one reflective layer 24 may range from about 10 nm to about 20 nm. It should be understood that the at least one reflective layer 24 may have any suitable thickness as desired. 【0067】 Advantageously, at least one reflective layer 24 may include voids 26 formed at at least one desired location to mitigate potential interference between the at least one reflective layer 24 and surrounding components (e.g., optical sensors 11, cameras, mobile phones, global positioning systems, road and parking transponders, and various other sensors). The voids 26 within the at least one reflective layer 24 may be formed during the manufacture of the glass article 10 (e.g., by masking the glass article 10 at desired locations) or during the removal of a portion of the at least one reflective layer 24 by any suitable method, such as laser or mechanical removal or etching. The voids 26 within the at least one reflective layer 24 may cover at least one continuous region and may take the form of a desired configuration, such as a linear or grid pattern. 【0068】 As illustrated, the glass article 10 may further include a first optical layer or anti-reflective (AR) layer 30. The AR layer 30 may be configured to enhance light transmission through the glass article 10. Preferably, the AR layer 30 may be formed on the second main surface 4 of the second sheet 14. More preferably, the AR layer 30 may be formed directly on the second main surface 4 of the second sheet 14 without substantially an intervening layer. However, it should be understood that the AR layer 30 may be formed on other surfaces of the glass article 10, such as the first main surface 1 of the first sheet 12. In non-limiting examples, the AR layer 30 may be an additional coating deposited on the second sheet 14, or an anti-reflective film disposed thereon. The AR layer 30 may extend substantially over the entire surface of the first sheet 12 and the second sheet 14, or it may be formed to extend only over a portion of their surfaces. 【0069】 In one embodiment, the AR layer 30 may be a single-layer coating containing silicon dioxide (SiO2) deposited by chemical vapor deposition (CVD). In another embodiment, the AR layer 30 may be a single-layer coating containing titanium oxide (TiO2) nanoparticles deposited by a sol-gel process. It should be understood that the AR layer 30 may, if desired, be a multilayer coating formed of any suitable material by any suitable method. 【0070】 The AR layer 30 may be selectively formed to a desired thickness to achieve a desired transmittance. In certain embodiments, the thickness of the AR layer 30 may be such that optimal transmission is achieved for at least one of the first and second wavelengths passing through the glass article 10. Preferably, the thickness of the AR layer 30 may be such that a transmittance of at least 80% is achieved for at least one of the first and second wavelengths passing through the glass article 10. More preferably, the thickness of the AR layer 30 may be such that a transmittance of at least 90% is achieved for at least one of the first and second wavelengths passing through the glass article 10. Most preferably, the thickness of the AR layer 30 may be such that a transmittance of at least 94% is achieved for at least one of the first and second wavelengths passing through the glass article 10. 【0071】 In certain embodiments, the AR layer 30 may be deposited with a thickness of about 80 nm or more, more preferably about 100 nm or more. In other embodiments, the thickness of the AR layer 30 may be in the range of about 80 nm to about 400 nm, preferably in the range of about 80 nm to about 160 nm, more preferably in the range of about 120 nm to about 150 nm. 【0072】 Preferably, the glass article 10 may be configured such that the light transmittance (measured with CIE light source A) in the area of ​​the glass article 10 visible to the vehicle occupants is substantially the same as that of the glass article 10 without the AR layer 30, while the light transmittance (measured with CIE light source A) at at least one of the first and second wavelengths in the area of ​​the glass article 10 aligned with the optical sensor 11 may be greater than that of the glass article 10 without the AR layer 30. Preferably, the light transmittance (measured with CIE light source A) at at least one of the first and second wavelengths in the area of ​​the glass article 10 aligned with the optical sensor 11 may be the maximum. 【0073】 In certain embodiments, the glass article 10 may further include a second optical layer or visible light (VL) reflective layer 40. As shown in Figure 2, the VL reflective layer 40 may be located adjacent to the AR layer 30. In one embodiment, the VL reflective layer 40 may be located on the surface of the AR layer 30 opposite to the second sheet 14. The illustrated VL reflective layer 40 reflects visible light with minimal or no effect on the transmission of infrared light through the glass article 10. In one embodiment, the VL reflective layer 40 may be a coating containing tin oxide (SnO2). The VL reflective layer 40 made of tin oxide also enhances the durability of the glass article 10. The VL reflective layer 40 may comprise a metal oxide having a refractive index greater than 1.6 (e.g., aluminum oxide (Al2O3), titanium dioxide (TiO2), chromium oxide (Cr2O3), niobium oxide (NbO)). 【0074】 In certain embodiments, the VL reflective layer 40 may be deposited by sputtering. Various other methods may be used to form the VL reflective layer 40 as needed. The VL reflective layer 40 may be formed to extend substantially over the entire surface of the AR layer 30, or it may be formed to extend only over a portion of its surface. In certain embodiments, the VL reflective layer 40 may be positioned above the AR layer 30 within the area of ​​the HUD system 8 to reflect visible light and enable proper operation of the HUD system 8. The thickness of the VL reflective layer 40 may be in the range of about 5 nm to about 20 nm, preferably in the range of about 5 nm to about 12 nm, more preferably in the range of about 6 nm to about 9 nm. It should be understood that the VL reflective layer 40 may have any suitable thickness as desired. 【0075】 In a preferred embodiment, the VL reflective layer 40 may contain a metal oxide having a refractive index of 1.6 or more and less than 1.8 and a thickness of 30 nm or less. In a more preferred embodiment, the VL reflective layer 40 may contain a metal oxide having a refractive index of 1.8 or more and a thickness of 20 nm or less. 【0076】 In certain embodiments, the optical sensor 11 may be a LiDAR-type sensor. Such LiDAR sensors include, but are not limited to, pedestrian detection sensors, pre-collision sensors, approach speed sensors, and adaptive cruise control sensors. In other embodiments, the optical sensor 11 may be an optoelectronic system comprising at least a laser or sensing beam transmitter, a receiver including at least a light or sensing beam collector (telescope or other optical system), and at least one photodetector that converts the light or sensing beam into an electrical signal and an electronically processed chain signal that extracts the desired information. 【0077】 The optical sensor 11 may be configured to emit a sensing beam through a glass article 10 and strike a distant object. The sensing beam may be reflected from the object, returned through the glass article 10, and detected by a receiver of the optical sensor 11. In most cases, the initial sensing beam emitted from the optical sensor 11 and the reflected sensing beam received by the optical sensor 11 may each have the same wavelength, preferably one of a first and a second wavelength. At least one photodetector may be configured to convert the sensing beam into an electrical signal, which can then be transmitted to a controller or microcontroller (not shown). 【0078】 As illustrated, the optical sensor 11 may be positioned on the second main surface 4 of the second sheet 12. However, it should be understood that the optical sensor 11 may be positioned on the glass article 10 or at other suitable location adjacent to the glass article 10. In certain embodiments, the optical sensor 11 may be positioned in alignment with a gap 26 formed in at least one reflective layer 24 and at least a portion of the AR layer 30, minimizing interference and maximizing the transmittance of at least one wavelength through the glass article 10, thereby improving the accuracy and reliability of the optical sensor 11. 【0079】 In a preferred embodiment, the glass article 10 includes a first sheet 12 having at least one reflective layer 24 positioned adjacent to its second main surface 2. A single-layer adhesive layer 16 may be positioned adjacent to the at least one reflective layer 24.

In certain embodiments, the first and second sheets 12', 14' may be manufactured from any glass composition and may be manufactured using any glass manufacturing process. Preferably, each of the first and second sheets 12', 14' may be manufactured from a soda-lime silica material.

Furthermore, the thickness of each of the first sheet 12' and the second sheet 14' may differ between embodiments of the glass article 10'.

In certain embodiments, the glass article 10' may include a plurality of reflective layers 24' positioned adjacent to at least one of the first and second sheets 12', 14' and incorporated into the multilayer intermediate layer 16'.
