Description

Technical Field

[0001] The utility model relates to the technical field of sunglasses, in particular to a light-adjustable sunglasses structure. Background Art

[0002] Sunglasses, also known as visors, are used for sunshade. People usually adjust the size of their pupils to adjust the light flux in the sun. When the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activities, especially in summer, it is necessary to use visors to block the sun to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation. There are three main types of sunglasses on the market. Colored glasses absorb some wavelengths of sunlight that are harmful to humans, polarized glasses mainly absorb polarized light reflected from the road, and photochromic glasses can adjust the brightness according to the intensity of sunlight.

[0003] Sunglasses in the prior art adjust the brightness by the intensity of sunlight, and cannot block polarized light reflected from the road while absorbing sunlight, making the sunglasses not very practical. Utility Model Content

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0021] A dimmable sunglass structure, referring to Figure 1 and Figure 2 , including a sunglass body 10, which includes a mirror film 11, a liquid crystal display layer 12 and a lower polarizer 13 arranged in sequence. Among them, the mirror film 11 is a semi-reflective and semi-lens mask, and the mirror film 11 is made of a linear polarization material, which can prevent polarized light reflected by the road from entering the eyes.

[0022] Reference Figure 2 The liquid crystal display layer 12 mainly includes an upper glass 121, a lower glass 122, and a liquid crystal layer 123 disposed between the upper glass 121 and the lower glass 122. The liquid crystal layer 123 is composed of a plurality of liquid crystal molecules. When the liquid crystal display layer 12 is powered on, light enters the liquid crystal layer 123, and the plurality of liquid crystal molecules are deflected.

[0023] Reference Figure 2 The size of the upper glass 121 is larger than that of the lower glass 122, the length of the lower end of the upper glass 121 is larger than the length of the lower end of the lower glass 122, and an FPC20 is bound to the side of the upper glass 121 facing the lower glass 122. One end of the FPC20 is bound to the upper glass 121 beyond the range of the lower glass 122, and the other end of the FPC20 is used to connect to the customer's mainboard so that the liquid crystal display layer 12 is powered on and can be used normally.

[0024] Further, refer to Figure 2 The polarization directions of the mirror film 11 and the lower polarizer 13 are arranged in parallel. When the liquid crystal display layer 12 is not lit, the sunlight enters the mirror film 11 and becomes polarized light, and the brightness is only about 50%. Since the liquid crystal display layer 12 is not lit, the light entering the liquid crystal display layer 12 is rotated 90 degrees by the liquid crystal molecules, so that the polarization angle of the mirror film 11 and the lower polarizer 13 is set at 90 degrees. Therefore, the light cannot pass through the lower polarizer 13. Only a small part of the light can pass through the lower polarizer 13. Most of the light is reflected back by the lower polarizer 13, and the reflected light is about 45%, making the sunglass body 10 look like a mirror from the outside. When the liquid crystal display layer 12 is turned on, the liquid crystal molecules in the liquid crystal layer 123 are deflected by the electric field, and the external light entering the liquid crystal display layer 12 through the mirror film 11 will not rotate. At this time, the polarization angles of the mirror film 11 and the lower polarizer 13 are parallel, so that most of the light passes through the lower polarizer 13, and only about 9% of the light is reflected back by the lower polarizer 13.

[0025] Reference Figure 2, a photosensitive element 30 for sensing light intensity is arranged on the side of the lower polarizer 13 away from the lower glass 122, and the photosensitive element 30 is connected to the customer main board. A photosensitive hole 40 for light to enter is provided at the mirror film 11 and the lower glass 122 relative to the photosensitive element 30. When light passes through the photosensitive hole 40 and reaches the photosensitive element 30, the power-on voltage of the customer main board to the liquid crystal display layer 12 is adjusted by sensing the light intensity to adjust the transmittance of the sunglass body 10. When the external light is strong, the power-on voltage is adjusted to a low light transmittance, and when the external light is weak, the power-on voltage is adjusted to a high light transmittance.

[0026] Reference Figure 2 The upper surface of the sunglass body 10 is covered with a strengthening film 50 , and the strengthening film 50 is used to improve the strength of the sunglass body 10 .

[0027] Further, refer to Figure 2 A layer of photochromic film 60 is disposed on the upper surface of the strengthening film 50. The photochromic film 60 is made of silver halide material. When the ultraviolet rays in the sunlight are strong, the light irradiates the sunglass body 10, and the silver halide in the photochromic film 60 will decompose into halogen atoms and silver atoms to cover the surface of the sunglass body 10, so that the color of the sunglass body 10 becomes darker, thereby reducing the damage of ultraviolet rays to the eyes.

[0028] Further, refer to Figure 2 A waterproof film 70 is disposed on the upper surface of the photochromic film 60. The waterproof film 70 makes the sunglass body 10 waterproof, so that the sunglass body 10 can be protected from water and oil stains during daily use.

[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
