Description

Smart mirror-coated glasses with multi-color mirror patterns expressed on the lenses

[0001] The present invention relates to glasses, and more particularly, to smart mirror-coated glasses that can be either regular glasses or mirror glasses depending on the user's desired situation, and that can block ultraviolet rays or scattered light, and that can also provide beautiful colors and style to the wearer by expressing a multi-color mirror pattern on the lens.

[0002] These days, glasses are no longer just a tool for poor eyesight; they're becoming a fashion statement. Some people focus on the frame, others on the color of the lenses, and still others are meticulous about both.

[0003] Among eyeglass lenses, there are those with colored mirror coatings. Mirror coatings, which create a mirror-like effect, were once incredibly popular, so much so that everyone tried them at least once. However, depending on the situation, the mirror coating can feel excessive, and in environments that don't match the environment, many people find it burdensome, making it difficult to wear consistently.

[0004] Recently, photochromic lenses have been incorporated into eyeglasses, darkening when exposed to sunlight. Photochromic lenses offer the advantage of being able to function as both glasses and sunglasses, and their convenience in many ways has made them popular.

[0005] Photochromic lenses change color when exposed to sunlight (ultraviolet rays), causing the lenses to take on a blue tint. This means they automatically change color in response to changing sunlight, darkening outdoors and returning to clear indoors.

[0006] However, photochromic lenses gradually fade indoors, even when UV rays are blocked (the color fades after 3-10 minutes). This means the color doesn't immediately clear, so others may find themselves uncomfortable with dark-tinted glasses. Furthermore, the photochromic effect deteriorates in indoor environments where sunlight (UV rays) is blocked.

[0007] Furthermore, UV-photochromic lenses have the disadvantage of not changing color well in high temperatures or humidity. Therefore, their performance deteriorates during the rainy season or in midsummer. Another drawback is that photochromic lenses lack a wide range of colors, which can make them feel dull.

[0008] If it could be used as regular glasses or mirrored glasses according to the user's desired situation regardless of sunlight (ultraviolet rays), and could have effects such as blocking ultraviolet rays or scattered light, and could provide beautiful colors and style to the wearer, it would be well-received by many people.

[0009] Accordingly, the purpose of the present invention is to provide smart mirror-coated glasses that can be used as regular glasses or mirror glasses according to the user's desired situation regardless of sunlight (ultraviolet rays), and that can block ultraviolet rays or scattered light, and that can express various colored mirror patterns on the lenses to provide beautiful colors and style to the wearer.

[0010] The present invention, in accordance with the above-described purpose, comprises a smart mirror-coated eyeglasses having a multi-color mirror pattern expressed on the lens, comprising an eyeglass lens capable of both sunglasses function and eyeglass function, a user touch unit, a light detection unit, and an electrochromic switching unit for switching between the sunglasses function and the eyeglass function, a function control unit for controlling the electrochromic switching unit with input from the user touch unit and the light detection unit, and an eyeglass frame having a power supply unit;

[0011] The above spectacle lens is configured such that a half-mirror layer capable of forming a full-view transparent window or mirror surface, an electrochromic layer configured to form an electrochromic element surface on the rear side of the half-mirror layer, and a lens body layer are sequentially arranged, and the electrochromic switching unit is switched in the function control unit according to the input of the user touch unit and the light detection unit, so that the electrochromic layer located at the rear side of the half-mirror layer changes color to a dark color for a blackout background by the power supply unit, thereby forming a full-view mirror surface in the half-mirror layer, thereby exhibiting a sunglasses function in the spectacle lens, and the half-mirror layer changes color to a transparent color, thereby exhibiting a spectacle function in the spectacle lens, wherein the half-mirror layer forms a full-view transparent window.

[0012] The half-mirror layer is characterized by having a half-mirror surface in which a multi-color mirror pattern having a design and color desired by the manufacturer is coated on a transparent base layer, and a mirror base surface having a color different from the multi-color mirror pattern is coated on a portion other than the multi-color mirror pattern.

[0013] Unlike existing photochromic lenses that change color depending on sunlight (ultraviolet rays), the present invention can instantly become regular glasses or mirror glasses according to the user's desired situation regardless of sunlight, and can exhibit effects such as blocking ultraviolet rays or scattered light. In addition, it has the advantage of providing the wearer with beautiful colors and stylish designs by allowing mirror patterns of various colors and designs to be expressed on the lenses.

[0022] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0023] FIG. 1 is a perspective view of smart mirror-coated glasses (2) according to an embodiment of the present invention, and FIG. 2 is an example of an application form of smart mirror-coated glasses (2) according to an embodiment of the present invention.

[0024] The smart mirror-coated glasses (2) according to an embodiment of the present invention can perform a sunglasses function like a mirror-coated eyeglass lens (6) as in (a) of FIG. 1 according to a user's desired environment or situation, or the smart mirror-coated glasses (2) can perform a general eyeglass function like a transparent eyeglass lens (6) as in (b) of FIG. 1.

[0025] The smart mirror coating glasses (2) of the present invention can be suitable for both sunglasses function and general glasses function, so that they can be manufactured in the form of glasses in which the glasses frame (4) is applied as a general glasses frame, as in (a) of FIG. 2, and can also be manufactured in the form of sports goggles in which the glasses frame (4) is applied as a sunglasses frame, as in (b) of FIG. 2.

[0026] In the smart mirror coating glasses (2) of the present invention, the 'sunglass function' means providing a front-side mirror effect that can provide beautiful colors and style from the front, while also providing a function to reduce glare, and can perform an eye protection function that can protect the eyes from not only sunlight or reflected scattered light, but also harmful ultraviolet rays.

[0027] In the smart mirror coating glasses (2) of the present invention, the 'glasses function' means that the glasses lens (6) is provided with a transparent window that becomes transparent when viewed from the front, and the transparent window of the glasses lens (6) can be fully realized even if it is a prescription lens, and can also perform the function of protecting the eyes from digital blue light.

[0028] FIG. 3 is a cross-sectional configuration diagram of a spectacle lens (6) of a smart mirror-coated spectacle lens (2) according to an embodiment of the present invention, and FIG. 4 is a configuration and circuit block diagram related to a spectacle lens (6) that combines a sunglasses function and a spectacle function according to an embodiment of the present invention.

[0029] Smart mirror coating glasses (2) according to an embodiment of the present invention are composed of a glasses lens (6) that can be used for both sunglasses and glasses functions, as shown in FIG. 1, and a glasses frame (4) in which glasses lenses (6) are combined on the left and right.

[0030] The eyeglass frame (4) is provided with a user touch unit (8) and a light detection unit (10) exposed to the outside, and as shown in the circuit block diagram of Fig. 4, an electrochromic switching unit (14) for switching between sunglasses function and eyeglass function by input from the user touch unit (8) and the light detection unit (10), and a function control unit (12) for controlling the electrochromic switching unit (14) are configured to be built into the eyeglass frame (4).

[0031] The spectacle lens (6) of the present invention is configured such that it can be used as both an instantaneous sunglasses function and an eyeglass function depending on the user's environment and situation, as shown in the cross-sectional configuration diagram of FIG. 3, not only is an anti-fingerprint layer (22) and a hard coating layer (24) sequentially formed, but also has a half-mirror layer (20) capable of forming a full-view transparent window or a mirror surface depending on the rear-side conditions. In addition, an electrochromic layer (30) is provided on the rear of the half-mirror layer (20) to serve as a background so that the half-mirror layer (20) has a full-view mirror effect or becomes a full-view transparent window, and a lens body layer (50) and a protective layer (60) are sequentially arranged on the rear of the electrochromic layer (30).

[0032] As shown in FIGS. 3 and 4, the half-mirror layer (20) is formed by sequentially stacking an anti-fingerprint layer (22) and a hard coating layer (24) on the front exposure side, and coating multilayer thin films including a reflective polarizing thin film and an absorptive polarizing thin film on the base glass surface (20a) by vacuum deposition to form a half-mirror surface (20b).

[0033] The mirror coating color in the half-mirror layer (20) is basically silver like a mirror surface, but gold and green are possible, and various colors such as blue, red, pink, etc. are also possible.

[0034] The mirror reflectivity and light transmittance of the half mirror layer (20) are formed at a ratio of 70 to 50% mirror reflectivity: 30 to 50% light transmittance, and while the front surface appears to be transparent glass in normal times, when the back surface of the half mirror layer (20) is formed as a background by blackout treatment using the electrochromic layer (30) of the present invention, a mirror of the color applied to the front surface is formed.

[0035] In the example of FIG. 5, the entire half-mirror surface (20b) of the half-mirror layer (20) constituting the spectacle lens (6) of the present invention is shown to be coated with various colors such as silver, gold, green, blue, red, pink, etc., and the spectacle lens (6) is shown to have a transparent form or the opacity of the corresponding coating color depending on the degree of exposure to UV light.

[0036] And the examples of FIGS. 8a to 8c show that the half-mirror surface (20b) of the half-mirror layer (20) constituting the spectacle lens (6) of the present invention can be formed into a mirror pattern (P1) having a design and color desired by the manufacturer, and that the mirror pattern (P1) has various opacity levels depending on the degree of exposure to UV light.

[0037] The half mirror layer (20) and the rear electrochromic layer (30) are bonded by a PVA polarizing adhesive film (26). The PVA [poly(ethylene vinylacetate)] polarizing adhesive film (26) has a structure in which a PVA material polarizing film that blocks ultraviolet rays and reflected light or digital blue light and an ultraviolet-curable adhesive is applied to both sides of the PVA material polarizing film.

[0038] The electrochromic layer (30) disposed on the rear of the half-mirror layer (20) is composed of an electrochromic surface portion (30a) and a solar cell surface portion (30b) positioned at the edge of the electrochromic surface portion (30a), as illustrated in FIG. 4, as an embodiment of the present invention. The electrochromic layer (30) according to the embodiment of the present invention utilizes energy generated by solar energy through the solar cell surface portion (30b) positioned at the edge of the lens.

[0039] The electrochromic surface portion (30a) of the electrochromic layer (30) according to the present invention is configured such that an ion storage surface layer (34), an electrolyte surface layer (36), an electrochromic element surface layer (38) having an operating electrode, and an upper conductive transparent substrate surface layer (40) are laminated and formed on the middle side of a lower conductive transparent substrate surface layer (32), as shown in FIG. 4.

[0040] And, the solar cell surface (30b) placed on the edge of the electrochromic layer (30) is similarly configured as shown in FIG. 4, in which a dye adsorption layer (42), an electrolyte surface layer (44), a transparent electrode surface layer (46), and an upper conductive transparent substrate surface layer (40) are laminated on the left and right sides of the lower conductive transparent substrate surface layer (32).

[0041] According to the present invention, the electrochromic layer (30) placed on the back side of the half-mirror layer (20) changes color to transparent or dark by using the self-generated electricity of the solar cell surface (30b) through the switching operation of the electrochromic switching unit (14) in the function control unit (12) built into the eyeglass frame (4) according to the input of at least one of the user touch unit (8) and the light detection unit (10) provided on the bridge side of the eyeglass frame (4).

[0042] According to an embodiment of the present invention, as the electrochromic layer (30) changes color to a dark color for a blackout background by the self-generated electricity of the solar cell surface (30b) under the control of the function control unit (12), the half-mirror layer (20) causes the sunglasses function of forming a full-view mirror surface to be expressed in the spectacle lens (6).

[0043] In addition, according to an embodiment of the present invention, as the electrochromic layer (30) is converted into a transparent color by the self-generated electricity of the solar cell surface (30b) under the control of the function control unit (12), the half-mirror layer (20) is configured to have a spectacle function in which a full-face transparent window is formed on the spectacle lens (6).

[0044] The dark color for the blackout background is clearly visible on the back of the eyeglass lens (6) with the sunglasses function, but the eyeglass wearer can comfortably view the front subject while receiving various protections through the eyeglass lens (6).

[0045] In the present invention, the user touch part (8) located on one side of the bridge of the eyeglass frame (4) operates in automatic mode and manual mode.

[0046] For example, if the user touch unit (8) is touched once with a finger, it operates in manual mode. An electrochromic toggle command is input based on a single touch, and if the user touch unit (8) is touched twice consecutively with a finger, it switches to automatic mode.

[0047] When the user touches the touch part (8) once, it is recognized as manual mode, and under the control of the function control part (12), the electrochromic layer (30) of the spectacle lens (6) is immediately switched from the currently maintained discoloration state to the opposite discoloration state.

[0048] When the user touches the touch part (8) twice in succession, it is recognized as an automatic mode, and in the automatic mode, the function control part (12) adaptively changes the discoloration state of the electrochromic layer (30) based on the amount of ultraviolet light from the light detection part (10). When the amount of light detected from the light detection part (10) is high, the function control part (12) discolors the electrochromic layer (30) to a dark color for a blackout background, and when the amount of light detected from the light detection part (10) is low, the function control part (12) discolors the electrochromic layer (30) to a transparent color.

[0049] The spectacle lens (6) having an electrochromic layer (30) according to the present invention can change the discoloration function instantly whenever the user wants, and when switched to automatic mode, the spectacle lens (6) can change the discoloration function according to the amount of light (ultraviolet rays), thus providing convenience to the spectacle wearer.

[0050] In addition, in the embodiment of the present invention, electricity for driving the electrochromic layer (30) is generated on its own, so separate charging is not required.

[0051] Therefore, since the glasses wearer can instantly perform the sunglasses function and the glasses function whenever he or she wants, unlike glasses with photochromic lenses, when entering a room or driving a vehicle into a tunnel, the light detection unit (10) immediately recognizes and the glasses lens (6) is immediately changed to transparent by the instantaneous discoloration reflection in the electrochromic layer (30), and in an external environment with sunlight, the glasses lens (6) appears like a full-view mirror by the instantaneous discoloration reflection in the light detection unit (10) and the electrochromic layer (30), and not only blocks glare but also blocks ultraviolet rays and reflected light.

[0052] Unlike photochromic lenses that do not change color quickly even when brought indoors, the glasses (2) of the present invention have excellent environmental adaptability and have excellent color change performance that is different from photochromic lenses that do not change color well when exposed to temperature or humidity.

[0053] In addition, the present invention can block most of the ultraviolet rays and glare, and can be implemented in various colors and can be implemented in a mirror-like appearance, so that it can provide beautiful colors and style to the wearer, for activities in places with high intensity of ultraviolet rays and visible light, such as rivers, lakes, and the sea, or for activities such as aviation sports, desert and remote areas exploration, mountaineering, and skiing.

[0054] In Fig. 5, the colors of the front-viewing spectacle lens (6) as a sunglasses function are shown as silver (a), gold (b), green (c), blue (d), red (e), and pink (f), and the glasses function is shown as an example in which the front-viewing spectacle lens (6) forms transparent windows (a) to (f).

[0055] Meanwhile, in the embodiment of the present invention described above with reference to FIGS. 3 and 4, the electrochromic layer (30) of the spectacle lens (6) has been described as an example in which a solar cell surface (30b) that generates electricity on its own is provided, but it can also be implemented as a modified example of the embodiment of the present invention as in FIGS. 6 and 7.

[0056] Fig. 6 is a cross-sectional configuration diagram of a spectacle lens (6) of a smart mirror-coated spectacle lens (2) according to a modified embodiment of the present invention, and Fig. 7 is a configuration and circuit block diagram related to a spectacle lens (6) having a sunglasses function and a spectacle function according to a modified embodiment of the present invention.

[0057] In FIGS. 6 and 7, the smart mirror coating glasses (2) are provided with an energy harvesting unit (70) for self-generation of energy built into the glasses frame (4) to replace the solar cell surface (30b) in the electrochromic layer (30) in the glasses lens (6) in FIG. 4.

[0058] The energy harvesting unit (70) can convert energy such as sunlight or the vibration of the movement of a wearer wearing smart mirror-coated glasses (2) into electricity to drive the electrochromic layer (30).

[0059] In the modified embodiment of FIG. 6, the electrochromic layer (30) in the spectacle lens (6) has a configuration without a solar cell surface (30b of FIG. 4), and has a configuration in which an ion storage surface layer (34), an electrolyte surface layer (36), an electrochromic element surface layer (38) having an operating electrode, and an upper conductive transparent substrate surface layer (40) are laminated and formed on a lower conductive transparent substrate layer (32).

[0060] The electrochromic layer (30) in the eyeglass lens (6) can perform a discoloration function using electric energy generated by the energy harvesting unit (70) built into the eyeglass frame (4).

[0061] Referring again to FIGS. 3 and 6, the lens body layer (50) formed by laminating the rear portion of the electrochromic layer (30) in the spectacle lens (6) of the present invention can be made of glass or a plastic material for spectacles, and can also be manufactured in the form of a prescription lens. The rear portion of the lens body layer (50) is configured to have a protective layer (60) having anti-fingerprint properties, etc.

[0062] The spectacle lens (6) of the present invention can function as sunglasses by changing color to produce a mirror effect by the half-mirror layer (20) and the electrochromic layer (30), and there is no problem at all in which the discoloration concentration changes according to the variation in the thickness of the lens, as in the case of prescription lenses.

[0063] In embodiments of the present invention or variations of the embodiments, energy self-generation is possible, but if necessary, a built-in battery, a power switch, and a charging port for charging the built-in battery through a USB cable may be further provided in the glasses frame (4), and a power wireless supply unit having a wireless electric coil for wirelessly supplying power may be provided so that charging is possible without a wired charging port.

[0064] Meanwhile, the spectacle lens (6) of FIGS. 3, 4, 6, and 7 has a half-mirror surface (20b) of the half-mirror layer (20) formed with a multi-color mirror pattern (P1 to P4) among various colors having a design desired by the manufacturer, as shown in FIGS. 8a, 8b, 8c, and 8d, so that the spectacle lens (6) can provide the wearer with a beautiful color and the coolness of a design pattern.

[0065] Referring again to FIGS. 8a, 8b, 8c and 8d, it should be understood that the expression of the degree of darkness of the half-mirror surface (20b) in the portion excluding the polychromatic mirror patterns (P1 to P4) has been omitted in FIGS. 8a to 8d to better illustrate the opacity of the polychromatic mirror patterns (P1 to P4) (mirror base surface P5).

[0066] The polychromatic mirror patterns (P1 to P4) in Fig. 8a are expressed as dark as possible because they are exposed to strong UV light, and the half-mirror layer (20) having the half-mirror surface (20b) is very opaque. The polychromatic mirror patterns (P1 to P4) in Fig. 8b are exposed to moderate UV light, and therefore the half-mirror layer (20) having the half-mirror surface (20b) is mostly opaque at moderate darkness. The polychromatic mirror patterns (P1 to P4) in Fig. 8c are exposed to weak UV light, and therefore the half-mirror layer (20) having the half-mirror surface (20b) is slightly opaque at minimum darkness.

[0067] And the multi-color mirror pattern (P1 to P4) in FIG. 8d is highly transparent because the half-mirror layer (20) having the half-mirror surface (20b) is exposed to no or minimal UV light.

[0068] The procedure for forming a multi-color mirror pattern (P1 to P4) in the half-mirror layer (20) of FIGS. 8a to 8d by coating on the surface of the transparent base layer (20a) in the half-coating layer (20) of the spectacle lens (6) can be performed as follows.

[0069] First, a mask having a negative masking pattern for coating a multi-color mirror pattern (P1 to P4) is prepared, and the mask of the negative masking pattern is attached on a transparent base layer (20a), and then treated with a multi-color mirror coating solution for pattern color, thereby forming a multi-color mirror pattern (P1 to P4) by coating on the transparent base layer (20a).

[0070] Afterwards, the mask having the negative masking pattern is removed, so that a half-mirror surface (20b) having a multi-color mirror pattern (P1 to P4) is formed on the half-mirror layer (20).

[0071] In addition, depending on the needs of the half-mirror layer (20), a different base color coating can be performed on a part (base surface P5) other than the multi-color mirror pattern (P1 to P4).

[0072] To this end, a mask having a positive masking pattern of a polychromatic mirror pattern (P1 to P4) is prepared. The mask having the prepared positive mask pattern is attached to the polychromatic mirror pattern (P1 to P4) that has been pre-coated on the transparent base layer (20a), and then additional coating is performed with a polychromatic mirror coating solution of a different color, so that a polychromatic mirror background (P5) is coated on the portion other than the mirror pattern (P1 to P4) on the transparent base layer (20a). Thereafter, by removing the mask having the positive mask pattern, a mirror background (P5) having a background color different from the color of the polychromatic mirror pattern (P1 to P4) is coated on the transparent base layer (20a) of the half-coating layer (20) as well as the polychromatic mirror pattern (P1 to P4) on the other portion.

[0073] Accordingly, the spectacle lens (6) of the present invention is formed with mirror patterns (P1 to P4) of various colors or a mirror base surface (P5) of a different color, and the mirror patterns (P1 to P5) can be displayed with various degrees of opacity depending on the degree of exposure to UV light. Each of the mirror patterns (P1 to P5) can be formed with one selected from various reflective colors such as silver, gold, green, blue, red, pink, orange, and purple.

[0074] While the above description of the present invention has described specific embodiments, various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be determined by the described embodiments, but by the claims and their equivalents.

[0075] The present invention can be applied to smart mirror-coated glasses that can provide beautiful colors and style to the glasses of a wearer who wants a multi-color mirror pattern expressed on the lenses.
