KR-102962688-B1 - SMART MIRROR COATING GLASSES HAVING MUTI-COLOR MIRROR PATTERNS REPRESENTED ON THE LENS

Abstract

The present invention relates to smart mirror-coated eyeglasses in which a multi-color mirror pattern is expressed on the eyeglass lens, comprising an eyeglass lens capable of combining sunglasses and eyeglass functions with a multi-color mirror pattern expressed on the front lens surface, and an eyeglass frame equipped with a user touch unit, a light detection unit, an electrochromic switching unit for converting between the sunglasses function and the eyeglass function, and a function control unit that controls the electrochromic switching unit based on input from either the user touch unit or the light detection unit. The invention is configured such that, through the switching operation of the electrochromic switching unit in the function control unit based on input from either the user touch unit or the light detection unit, the electrochromic layer positioned behind the half-mirror layer, on which a multichromatic mirror pattern of a design and color desired by the manufacturer is coated, changes color to a dark color suitable for a blackout background by supplying electricity from a power supply unit, thereby enabling the sunglasses function in which the half-mirror layer forms a mirror surface on the front image, and the eyeglass function in which the electrochromic layer changes to a transparent color, thereby enabling the eyeglass lens to form a transparent window on the front image, unlike conventional photochromic lenses that change color according to sunlight (ultraviolet rays). Regardless of sunlight, it can instantly function as regular glasses or mirrored glasses to suit the user's desired situation, and can provide effects such as UV protection or blocking scattered light, while offering the wearer beautiful colors and style.

1. In smart mirror-coated glasses in which a multi-color mirror pattern is expressed on the lens, Eyeglass lenses (6) that can be used for both sunglasses and eyeglasses, The glasses frame (4) is composed of a user touch unit (8), a light detection unit (10), an electrochromic switching unit (14) for converting between sunglasses function and glasses function, a function control unit (12) for controlling the electrochromic switching unit (14) with input from either the user touch unit (8) or the light detection unit (10), and a power supply unit; The above eyeglass lens (6); A fingerprint-resistant layer (22) and a hard coating layer (24) are formed in sequence, and a half mirror layer (20) capable of forming a front-facing transparent window or a mirror surface depending on the rear side conditions, an electrochromic layer (30) configured such that an electrochromic element surface (30a) is formed on the rear of the half mirror layer (20), a lens body layer (50), and a protective layer (60) are arranged in sequence. By switching operation of the electrochromic switching unit (14) in the function control unit (12) according to input between the user touch unit (8) and the light detection unit (10), the electrochromic layer (30) placed at the back position of the half mirror layer (20) changes to a dark color for a blackout background by supplying electricity from the power supply unit, thereby causing the half mirror layer (20) to form a mirror surface on the front and the sunglasses function to be manifested on the eyeglass lens (6), and as the electrochromic layer (30) changes to a transparent color, the half mirror layer (20) is configured to form a transparent window on the front and the eyeglass function to be manifested on the eyeglass lens (6). The half mirror layer (20) is provided with a half mirror surface (20b) in which a polychromatic mirror pattern (P1, P2, P3, P4) having a design and color desired by the manufacturer is coated on a transparent base layer (20a), and a mirror base surface (P5) having a color different from the polychromatic mirror pattern (P1, P2, P3, P4) is coated on the portion other than the polychromatic mirror pattern (P1, P2, P3, P4). The mirror reflectance and light transmittance of the above-mentioned half-mirror layer (20) are composed in a ratio of 70~50% mirror reflectance : 30~50% light transmittance, and The above half mirror layer (20) and the rear electrochromic layer (30) are bonded by a PVA polarizing adhesive film (26), and the PVA polarizing adhesive film (26) is a PVA material polarizing film that blocks ultraviolet rays and reflected light or blocks digital blue light, and an ultraviolet curable adhesive is applied to both sides of the PVA material polarizing film. The electrochromic surface portion (30a) of the above electrochromic layer (30) is formed by stacking 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) on the middle side of the lower conductive transparent substrate surface layer (32). Smart mirror-coated glasses with a multi-color mirror pattern expressed on the lens, characterized in that the solar cell surface portion (30b) disposed at the edge of the electrochromic layer (30) has 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) laminated on both the left and right sides of the lower conductive transparent substrate surface layer (32).

Description

Smart mirror-coated glasses having multi-color mirror patterns expressed on the lenses The present invention relates to eyeglasses, and more specifically, to smart mirror-coated eyeglasses that can function as ordinary eyeglasses or mirror eyeglasses depending on the situation desired by the user, can block ultraviolet rays or scattered light, and can present beautiful colors and style to the wearer by expressing a multi-color mirror pattern on the lens. Nowadays, glasses have established themselves as a fashion item, going beyond being merely a tool worn for poor eyesight. Some people focus on the frame, others on the lens color, and still others pay attention to both the frame and the lenses. Among eyeglass lenses, there are lenses with colored mirror coatings. Mirror-coated glasses, which reflect like a mirror when applied to the lens, were once such a huge trend that people tried wearing them at least once. However, depending on the situation, the mirror coating on the lenses could feel excessive, and since many people might find it burdensome in environments that do not match their surroundings, it was difficult to wear them continuously. Recently, there are also eyeglass products featuring photochromic lenses that darken when exposed to sunlight. Photochromic lenses are sought after by many people because they offer the advantage of serving as both eyeglasses and sunglasses, making them convenient in many ways. Photochromic lenses change color when exposed to sunlight (ultraviolet rays), causing the lenses to turn blue. In other words, they automatically change color according to changing sunlight, becoming dark outdoors and returning to transparent indoors. However, even after entering indoors and blocking UV rays, the color inside the photochromic lenses gradually fades (the color fades after 3 to 10 minutes). In other words, since the lenses do not become transparent immediately, there is a disadvantage in that one may be self-conscious about the stares of others who find the dark lenses uncomfortable. Additionally, there is a drawback in that the photochromic function deteriorates when sunlight (UV rays) is blocked, such as under indoor lighting. Furthermore, UV photochromic lenses have the disadvantage of not changing color effectively when the temperature or humidity is high. For this reason, their performance deteriorates during the summer rainy season or midsummer. Another drawback is that photochromic lenses cannot support a wide variety of colors, which can feel somewhat monotonous. If the glasses could function as regular glasses or mirrored glasses regardless of sunlight (UV rays), adapt to the user's desired situation, and provide effects such as UV protection or blocking scattered light, while offering the wearer beautiful colors and style, they would likely receive a great response from many people.
