Description

Technical Field

[0001] The utility model relates to the technical field of light-feeding instrument equipment, in particular to a glasses-type light-feeding instrument. Background Art

[0002] The phototherapy device is a photobiotherapy product that uses red light. Its main function is to prevent and control myopia and relieve dry eyes and pain caused by prolonged eye use. With the development of society and technology, environmental factors related to modern life, such as the prevalence of electronic products such as computers and mobile phones, have led to widespread overuse of the eyes.

[0003] Currently, various phototherapy devices have been widely researched and applied as myopia prevention and control devices. Among them, phototherapy devices use a specific red light with a wavelength between 630-650 nanometers to irradiate the human retina for an effective period of time. This specific red light of 630-650 nanometers is beneficial, promoting dopamine secretion in the retina and strengthening the choroid and sclera, effectively controlling excessive eye axial growth and thus preventing the onset and progression of myopia.

[0004] Currently, most light-feeding devices use lasers as the light emission source of a specific wavelength, which is in close contact with the human eye. In addition, electronic products have unstable factors. Lasers are also high-energy concentrated light sources, which may cause eye irritation. The light-feeding devices on the market now have light sources, circuits, and mechanical components. They are generally large in size, which is not conducive to use and carrying.

[0023] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0024] See also Figure 1 , Figure 1 : This is a schematic diagram of the three-dimensional structure of the glasses-type light-feeding device provided by an embodiment of the present invention. The glasses-type light-feeding device of the present invention includes a filter 1, a glasses frame 2, a light-shielding tube 3, and a light-shielding hood 4. The filter 1 is mounted on the glasses frame 2 and corresponds to the position of the wearer's eyes to filter natural light and allow red light with a wavelength of 630nm-650nm to pass. The light-shielding tube 3 is located on the side of the filter 1 away from the wearer and is connected to the glasses frame 2 to block natural direct light. The light-shielding hood 4 is located on the side of the filter 1 close to the wearer and is connected to the glasses frame 2 to fit the wearer's eyes.

[0025] By installing the filter 1 on the glasses frame 2, when the wearer wears the glasses-type light-feeding device of the present invention, the natural light can be filtered under the action of the filter 1, and red light with a wavelength of 630nm-650nm is allowed to pass through, so that the red light passing through the filter 1 can irradiate the retina of the human eye, promote the retina to secrete dopamine, strengthen the choroid and sclera, so as to achieve the purpose of effectively controlling the excessive growth of the eye axis, and thus prevent and control the occurrence of myopia and the increase in degree.

[0026] By arranging the light shield 4 and the light shielding tube 3 on both sides of the filter 1 respectively, when the wearer wears the glasses-type light feeding device, the light shielding tube 3 can block the natural direct light to prevent the natural direct light from irritating the eyes, and the light shield 4 can block the side light to prevent the light from entering the eyes from the side of the light shield 4 and affecting the use effect of the light feeding device.

[0027] Compared with the large-scale light-feeding devices in the prior art, the glasses-type light-feeding device of the present invention enables users to wear it like glasses, making the glasses-type light-feeding device compact and convenient for users to carry. Under the action of the filter 1, natural light is filtered, and red light with a wavelength of 630nm-650nm is allowed to pass, thereby achieving the effect of preventing and controlling the occurrence of myopia and the increase of degree. By arranging a light-shielding tube 3 and a light-shielding hood 4 at both ends of the filter 1, the natural direct light is blocked under the action of the light-shielding tube 3 to prevent the natural direct light from irritating the eyes, and the side light is blocked under the action of the light-shielding hood 4 to prevent light from entering the eyes from the side of the light-shielding hood 4 and affecting the use effect of the light-feeding device.

[0028] In an embodiment of the present invention, the filter 1 for filtering red light with a wavelength of 630nm-650nm can be purchased directly from the market. By processing the size of the filter 1 so as to facilitate installation of the filter 1 on the eyeglass frame 2, the filtering effect of natural light is achieved, and red light with a wavelength of 630nm-650nm is allowed to pass through. The present invention does not make any improvements to the material and performance of the filter 1.

[0029] In the embodiment of the present invention, an array of grooves 7 are provided on the circumferential surface of the light-shielding cylinder 3 so that direct light forms diffuse reflection after passing through the grooves 7, thereby reducing the stimulation of the direct light to the eyes.

[0030] See also Figure 2 , Figure 2 This is a schematic diagram of the exploded structure of the light-shielding tube in the eyeglass-type light-feeding device provided by an embodiment of the present invention. In this embodiment of the present invention, the light-shielding tube 3 includes an inner light-shielding tube 32 and an outer light-shielding tube 31. One of the inner light-shielding tube 32 and the outer light-shielding tube 31 is fixedly connected to the eyeglass frame 2, while the other is rotatably connected relative to the eyeglass frame 2. The inner light-shielding tube 32 is provided with an array of first grooves 71 on its circumferential surface, while the outer light-shielding tube 31 is provided with an array of second grooves 72 on its circumferential surface.

[0031] By respectively providing a first groove 71 and a second groove 72 on the inner light-shielding tube 32 and the outer light-shielding tube 31, and making one of the inner light-shielding tube 32 and the outer light-shielding tube 31 fixedly connected to the eyeglass frame 2 and the other rotatably connected relative to the eyeglass frame 2, the first groove 71 and the second groove 72 can be misaligned when the inner light-shielding tube 32 or the outer light-shielding tube 31 is rotated, thereby realizing regulation of the size of the groove 7, and further realizing regulation of the amount of direct light exposure. When the size of the groove 7 is too small and the light inside the light-shielding tube 3 is insufficient, the light-shielding tube 3 is rotated to increase the misalignment of the first groove 71 and the second groove 72, thereby enlarging the size of the groove 7, thereby avoiding the wearer's observation field being too dark when the size of the groove 7 is too small. Conversely, when the size of the groove 7 is too large and the light inside the light-shielding tube 3 is overexposed, the light-shielding tube 3 is rotated to reduce the misalignment of the first groove 71 and the second groove 72, thereby reducing the size of the groove 7, thereby avoiding the wearer's observation field being overexposed when the size of the groove 7 is too large.

[0032] In an embodiment of the present invention, the size between two adjacent first grooves 71 is equal to the size of the second groove 72, thereby increasing the size adjustment range of the groove 7, that is, when the first groove 71 and the second groove 72 are rotated to the corresponding positions, the size of the groove 7 is the largest, so that more direct light passes through the groove 7 and forms diffuse reflection, avoiding the wearer's observation field of view being too dark. When the position between the two adjacent first grooves 71 and the second groove 72 is rotated to the corresponding position, the size of the groove 7 is the smallest, that is, the groove 7 is completely closed to avoid overexposure of direct light and damage to the wearer's glasses.

[0033] In an embodiment of the present utility model, the outer light-shielding tube 31 is fixedly connected to the eyeglass frame 2, and a rotating groove 33 is provided on the inner wall of the outer light-shielding tube 31, and a rotating platform 34 is provided on the outer wall of the inner light-shielding tube 32. The rotating platform 34 is located in the rotating groove 33 and is rotatably connected to the rotating groove 33. When the size of the groove 7 needs to be adjusted, the rotating platform 34 is rotated in the rotating groove 33 by rotating the inner light-shielding tube 32, so that the first groove 71 and the second groove 72 are misaligned to achieve adjustment of the size of the groove 7.

[0034] In an embodiment of the present invention, the outline size of the light-shielding tube 3 is adapted to the outline size of the filter 1, so that direct light can be filtered under the action of the light-shielding tube 3 to prevent direct light from entering the wearer's eyes from all sides of the filter 1 and causing damage to the wearer's eyes.

[0035] In the embodiment of the present utility model, the filter 1 is a circular filter 1 , the light-shielding cylinder 3 is a cylindrical light-shielding cylinder 3 , and the diameter of the filter 1 is adapted to the diameter of the light-shielding cylinder 3 .

[0036] In an embodiment of the present invention, temples 5 are provided on both sides of the glasses frame 2, and a rotating shaft 6 is provided at the connection between the temples 5 and the glasses frame 2. The temples 5 and the glasses frame 2 are rotatably connected through the rotating shaft 6, so that the wearer can rotate the temples 5 to open the temples 5 from the glasses frame 2, making it convenient for the wearer to wear the glasses-type light-receiving device. When idle, the glasses-type light-receiving device can be removed and the temples 5 can be folded to store the glasses-type light-receiving device.

[0037] In an embodiment of the present invention, a bending portion is provided on the side of the temple 5 away from the eyeglass frame 2, and the angle between the bending portion and the temple 5 is 60°, so that when the wearer wears the spectacles-type eyeglasses, the bending portion can fit the wearer's skull behind the ear, so as to increase the wearing stability of the spectacles-type eyeglasses, and prevent the spectacles-type eyeglasses from shaking on the bridge of the nose when the wearer exercises.

[0038] In an embodiment of the present invention, the lens hood 3 includes any one of a silicone lens hood and a rubber lens hood, so that the lens hood 3 fits tightly against the wearer's face, and the side light is blocked by the lens hood 3 to prevent light from entering the eyes from the side of the lens hood 3 and affecting the use effect of the light feeding instrument.
