[0029] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0030] Embodiment 1:

[0031] This embodiment provides a light-transmitting structure 6, such as Figure 1 A light-transmitting film 2 is plated on a light-transmitting substrate 1. The light-transmitting film 2 includes multiple film layers. The multiple film layers are superimposed. The different characteristics of different film layers are used to adjust the light-transmitting band of the light-transmitting film 2. For example, the light-transmitting film 2 can transmit red light, blue light, yellow light and other bands that are beneficial to the human body, and shield ultraviolet rays that are harmful to the human body, thereby playing a protective and beauty role on the human body.

[0032] In fact, long-wave ultraviolet rays UV-A (200-300nm) can darken the skin, cause skin spots, and lead to skin aging. Excessive UV-A can suppress the immune system. Medium-wave ultraviolet rays UV-B (300-400nm) can cause skin redness, blisters, and skin aging, which is commonly known as sunburn. UV-B can cause keratitis and conjunctivitis in the human eye. Long-term sunburn can cause cataracts and suppress the immune system, and even cause skin cancer. The ultraviolet effects described above refer to long-term and high-intensity exposure. Moderate and short-term exposure to sunlight ultraviolet rays is also beneficial. It can enhance a person's physical fitness and ability to resist infectious diseases, promote the synthesis of vitamin D3 in the body, maintain normal calcium and phosphorus metabolism and bone growth and development, accelerate wound healing, and improve immunity.

[0033] The blue light part (wavelength 400-500nm) in visible light has the highest photon energy in visible light. It can penetrate the lens directly to the retina, causing damage to the retina, leading to decreased vision, and may cause serious eye diseases. High-intensity blue light causes much more damage to the retina of the human eye than near-infrared light. The harm of blue light to the human eye has always existed in sunlight and artificial light sources. However, low-radiation blue light is also beneficial to the skin. Infant jaundice is treated by irradiating low-intensity blue light. Blue light can also whiten the skin and teeth. Blue light controls the human biological clock to a certain extent. The stimulation of blue light will promote our body to secrete cortisol, which can be exciting.

[0034] Near infrared rays (800-1200nm) can make human skin feel hot, dry and lose moisture, resulting in rough skin. High-intensity near infrared rays can cause skin burns. The human eyeball contains more fluid, which absorbs near infrared rays strongly. High-intensity infrared rays directly irradiate the eyes and can cause cataracts. Near infrared rays also have a beneficial side. For example, some medical devices use near infrared rays to irradiate local parts of the human body to increase the temperature, improve blood circulation, eliminate swelling and dissipate inflammation.

[0035] It can be seen that ultraviolet rays, blue light and near-infrared rays all have effects on human health, some good and some bad. Therefore, how to retain beneficial bands such as blue light, red light, yellow light or near-infrared rays as much as possible, and shield unnecessary bands to make full use of outdoor light.

[0036] like Figure 1As shown, the substrate 1 of this embodiment is a plastic material, such as PC / PMMA plastic material, so the substrate 1 is a soft transparent structure. Through the coating technology, a transparent film is coated on the substrate 1, and the transparent film includes a multi-layer first film layer 3 and a multi-layer second film layer 4, wherein the first film layer 3 and the second film layer 4 are alternately stacked, and different film layers can pass different spectral bands, so the transparent film can pass spectral bands by stacking the multi-layer film layers. Among them, the first film layer is made of a low refractive index material with a refractive index of 1.35-1.55; the second film layer is made of a high refractive index material with a refractive index of 1.9-2.3. In this embodiment, two film layers with different refractive indices are stacked cyclically, and the film thickness is adjusted according to the light band to be refracted by each film layer, that is, the thickness of each film layer of the light-transmitting film 2 is different. After stacking, a transparent film can be formed which can block UV, blue light and near-infrared light in sunlight at the same time, thereby achieving the effect of not affecting the visual effect and filtering out harmful light from the sunlight. Furthermore, after the light-transmitting structure 6 of this embodiment is applied to an outdoor sun hat, it can not only achieve sun protection outdoors, but also irradiate the skin with red light, low-radiation blue light, etc., to achieve the effect of improving the skin. Alternatively, the light-transmitting structure 6 of this embodiment can also be applied to other daily necessities, such as making a transparent umbrella, etc., which is not limited in this embodiment.

[0037] Embodiment 2:

[0038] The difference between this embodiment and the first embodiment is that the substrate 1 is glass, that is, in this embodiment, a transparent film is coated on the glass, so that the glass has the effect of blocking UV, blue light and near-infrared light in sunlight, and can also transmit light that is beneficial to the skin, thereby achieving the effect of protection and beauty. The glass of this embodiment is applied to the glass of vehicles, doors and windows of houses, etc., so that the space where people live can have the effect of sun protection, and can also have a certain skin protection function, and is highly practical.

[0039] Embodiment three:

[0040] This embodiment provides an outdoor beauty device, including a wearing component 5 and the light-transmitting structure 6 of the first embodiment. The wearing component 5 can be a hat, such as a sun hat. Figure 2As shown, the light-transmitting structure 6 is assembled to the hat, and the fixing method of the light-transmitting structure 6 and the hat is the existing technology, and this embodiment does not limit it. After the user puts on the hat, the light-transmitting structure 6 can block the face to achieve the effect of sun protection. At the same time, because the light-transmitting structure 6 can shield ultraviolet rays, near-infrared light and other light that may affect human health through light in the wavelength band that is beneficial to the human body, that is, outdoors, the user can also protect the skin and can use red light and blue light to soothe the skin, beautify, etc. For example, for users with acne, even if they can block ultraviolet rays, there are still many rays in the sunlight that can damage the skin. Therefore, for users with poor skin, wearing the hat of this embodiment, in addition to sun protection, can also use the red light, blue light, etc. passed by the light-transmitting structure 6 to achieve the effect of soothing skin care, thereby reducing further damage to the skin.

[0041] In the prior art, there are many beauty instruments, including row lights, etc., which can emit light of a specific wavelength, such as red light. The red light emitted by the row lights can be used to illuminate the face to achieve beauty effects. It can be seen that the nature of these beauty instruments is active, that is, these beauty instruments all need to be powered to use, and some beauty instruments are large in size and not convenient to carry outdoors. This embodiment, on the other hand, is a passive product that makes full use of light of different wavelengths of sunlight, retains the beneficial light in the sunlight through the light-transmitting structure 6, and shields the light that is harmful to the human body, thereby achieving the effect of protecting the skin. That is, this embodiment is suitable for outdoor use, does not require power supply, is not restricted by the use environment, and can be used anytime and anywhere by the user. Compared with beauty instruments, this embodiment has a lower cost and is more suitable for most people.

[0042] Embodiment 4:

[0043] This embodiment provides a method for manufacturing a light-transmitting structure 6, comprising the following steps:

[0044] S1, put the substrate 1 into the coating furnace cavity, add high refractive index material and low refractive index material into the coating furnace cavity, and then make the coating furnace cavity enter a vacuum state; wherein, the substrate 1 is preferably a PC / PMMA plastic plate, and the PC / PMMA plastic plate cut to a suitable size is placed on the coating worker's rotating umbrella plate, and an appropriate amount of coating material is added. There are two types of coating materials, including high refractive index material and low refractive index material. The temperature in the furnace is adjusted to 20°, the furnace door is closed to exhaust the vacuum, and the vacuum inside the box is waited to reach 2.0E-3MPa;

[0045] S2, ion cleaning, the surface of the substrate 1 is cleaned of foreign matter and dust by a plasma-assisted deposition device, including washing, degreasing and drying, so as to remove grease, dust and other impurities on the surface to ensure the quality of the coating; in fact, when the vacuum inside the box reaches 2.0E-3MPa, 50sccm of O2 and 15sccm of Ar are filled for ion start-up assistance, and the plasma-assisted deposition device is started, and 800V Voltage and 800mA Current are used to perform ion cleaning on the surface of the PC / PMMA plastic plate, the purpose of which is to remove the dust and foreign matter remaining on the surface of the PC / PMMA plastic plate, and prevent the problem of uneven film layer caused by the dust and foreign matter left inside the film layer after coating. In addition, the present embodiment uses a plasma-assisted deposition device for coating auxiliary work;

[0046] S3, evaporation coating, using an ion source to alternately evaporate high refractive index materials and low refractive index materials; after the above steps are completed, evaporation coating is performed, using high refractive index materials with coating refractive indices of 1.9-2.3 and low refractive index materials with refractive indices of 1.35-1.55, and the coating method is a cyclic stacking of two coating materials, such as Figure 1 As shown, the first film layer is a low refractive index material, the second film layer is a high refractive index material, and the stacking order from the inside to the outside is the first film layer, the second film layer, the first film layer, the second film layer...the first film layer, the innermost layer and the outermost layer are both low refractive index materials, and the total film thickness of the two materials is 3036nm, of which the first film layer is 1869nm and the second film layer is 1167nm;

[0047] S4. After the evaporation coating is completed, the plasma assisted deposition device is closed, the furnace cavity is cooled and inflated, and the door is opened, and then the plastic plate that has completed the evaporation coating is removed; further, the PC / PMMA plastic plate is cut into a suitable size according to the size of the human head and made into a sun hat. The sun hat can adjust the head circumference size according to the rubber band and Velcro.

[0048] Specifically, the coating materials of this embodiment are all deposited onto the substrate 1 in a physical manner, that is, by evaporation, and the deposition of different film layers is controlled according to different evaporation conditions of different materials. For example, during the evaporation process, the ion source needs to be turned on to assist the entire coating process, and different ion parameters are used for different materials. The evaporation of low refractive index materials uses 600V Voltage and 600mA Current, and is filled with 50sccm of O2 and 10sccm of Ar; the evaporation of high refractive index materials uses 600V Voltage and 600mA Current, and is filled with 80sccm of O2 and 10sccm of Ar.

[0049] In fact, it is difficult to use plastic sheets for coating:

[0050] Thermal stability: The thermal stability of plastic materials is much lower than that of glass. Most plastic materials have certain softening points and melting points. During the coating process, especially when using methods such as physical vapor deposition (PVD) or chemical vapor deposition (CVD), higher temperatures are required to evaporate or decompose the deposited materials. These high temperature conditions may cause the plastic sheet to deform, soften or even melt.

[0051] Chemical reactivity: Plastic materials react chemically with gases or vapors used in the coating process more easily than glass, which may result in reduced adhesion between the coating layer and the substrate 1 or produce undesirable by-products, affecting the quality and performance of the coating.

[0052] Surface tension and wettability: The surface tension and wettability of the plastic may affect the uniformity of the coating layer. Some coating materials may not form a continuous film on the plastic surface, but tend to form islands or irregular morphologies, depending on the surface energy of the plastic and the wetting behavior of the coating material.

[0053] Hardness and abrasion resistance: Plastics are generally not as hard and abrasion-resistant as glass, which may mean that the coating is more susceptible to scratches and wear, especially during subsequent processing and use.

[0054] Deformation and stress: During the coating process, due to the different thermal expansion coefficients of the coating material and the plastic substrate 1, stress may be generated during the cooling process, causing the coating layer to crack or fall off.

[0055] Cleaning and pretreatment: Plastic surfaces may be more susceptible to grease and contaminants. These impurities must be thoroughly removed before coating, otherwise they will affect the adhesion and optical properties of the coating.

[0056] Based on the above problems, coating on plastic plates is difficult, so in the actual coating process, workers need to overcome them. For example, in this embodiment, a plasma-assisted deposition device is used to assist evaporation, control the voltage and current required for different materials, and adjust and control the evaporation temperature to maintain the evaporation of the coating material without affecting the structure of the plastic plate and improving the flatness of the coating. Figure 1 As shown, this embodiment achieves different wavelengths of light reflected by different film layers by alternately stacking multiple film layers and controlling the thickness of the film layers, wherein the total thickness of the two materials is 3036nm, wherein the total thickness of the first film layer is 1869nm, and the total thickness of the second film layer is 1167nm, and both the innermost layer and the outermost layer are first film layers made of low refractive index materials, etc., such as Figure 3 The wavelength band passed by the coating in this embodiment is 500nm-1100nm, and the light sources of the wavelength band that are beneficial to the human body include:

[0057] 620nm red light effects: skin rejuvenation, wrinkle improvement, skin elasticity improvement, pigmentation improvement;

[0058] 590nm yellow light can reduce melanin in the skin, relieve acne scars, and brighten skin tone;

[0059] 415nm blue light can relieve inflammation, reduce skin allergies, and treat acne;

[0060] 850nm infrared light stimulates collagen regeneration, improves wrinkles and tightens the skin.

[0061] Ultraviolet rays (200nm-400nm), the blue light part of visible light (400nm-500nm), and near infrared rays (part of 1100nm-1200nm) that are harmful to the human body are all reflected by the transparent film and will not irradiate the human skin, thereby reducing the damage to the human skin. Therefore, this embodiment is applied to a sun hat to achieve the effects of sun protection and beauty at the same time, and can be used outdoors at any time without the need for electricity, making full use of sunlight to achieve more effects and being more practical.

[0062] Embodiment five:

[0063] The difference between this embodiment and the third embodiment is that this embodiment applies the coating process to glass, that is, the substrate 1 is glass, and the low refractive index material and the high refractive index material are also used for coating. Compared with plastic plates, glass is less likely to deform, melt, etc., and the structure is more stable, and the coating process will be easier. After coating by the coating process of the third embodiment, the glass with a transparent film can be applied to car windows, doors and windows of houses, etc., so that people can use sunlight for beauty treatment indoors, which is more suitable for daily use.
