Detailed Embodiment

[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0024] Refer to Figure 1-6, in an embodiment of the present utility model, a reflective film for a lens includes: a base layer 7, a base wall 14 is fixedly connected to the lower surface of the base layer 7. The base wall 14 is hexagonal, and there are multiple base walls 14 evenly distributed, enabling the reflective film base layer 7 to have the characteristics of multiple reflection surfaces and being easily flexed, providing good reflection intensity and avoiding deformation, warping during use, or falling off from the adhered article. A bonding layer 6 is fixedly connected to the lower surface of the base layer 7. A base groove 18 is provided on the upper surface of the bonding layer 6. The lower surface of the base wall 14 extends into the base groove 18 and is fixedly connected to the base groove 18, accommodating the base wall 14 to enhance the connection effect between the bonding layer 6 and the base layer 7, and connecting the functional components above the base layer 7 and the film basic components such as the intermediate layer 5 together. A reflective layer 8 is fixedly connected to the upper surface of the base layer 7, enabling the reflective film to have a good reflective effect. Glass microspheres 15 are fixedly connected inside the reflective layer 8. The glass microspheres 15 are hollow and colorless and transparent. There are multiple glass microspheres 15 evenly distributed, improving the reflective effect of the reflective layer 8 and also enhancing the heat insulation effect of the reflective film, preventing the adhesive layer 2 from melting when the temperature is too high and causing the reflective film to fall off;

[0025] A ceramic layer 9 is fixedly connected to the upper surface of the reflective layer 8 to prevent the contact object from penetrating the reflective film and damaging the lens lens. Micropores 16 are provided inside the ceramic layer 9. The micropores 16 are arranged in a net shape at the center of the ceramic layer 9. The ceramic carrier 10 is cross-distributed with the micropores 16, improving the flexibility of the ceramic layer 9, enabling the reflective film to have a certain toughness while being bent, and not being easily folded to affect the use of the lens. A ceramic carrier 10 is fixedly connected inside the ceramic layer 9, increasing the hardness of the ceramic layer 9, facilitating the protection of the reflective film and the lens lens from reduced damage. An insulating layer 11 is fixedly connected to the upper surface of the ceramic carrier 10, isolating infrared rays, reducing the heat absorption of the reflective film and resulting in a temperature rise, and improving the heat insulation efficiency of the reflective film. Wear-resistant particles 12 are fixedly connected to the upper surface of the insulating layer 11. There are multiple wear-resistant particles 12 evenly distributed. The wear-resistant particles 12 are composed of an organically modified silicone material. The wear-resistant particles 12 are hemispherical in shape, enabling the external object to come into contact with the wear-resistant particles 12 first when rubbing against the reflective film, reducing the wear of the reflective layer 8 in the reflective film and affecting the various functions of the reflective film. A rubber block 17 is fixedly connected to the upper surface of the wear-resistant particles 12. There are multiple rubber blocks 17 evenly distributed. A spacer layer 19 is located between the rubber blocks 17, enabling the coloring layer 13 to be fixed on the reflective film. One end of the rubber block 17 away from the wear-resistant particles 12 is fixedly connected to the coloring layer 13, enabling the reflective film to have different colors and reducing the influence of sunlight irradiation on the functions of the reflective film during transportation. A spacer layer 19 is fixedly connected to the lower surface of the coloring layer 13, dividing the rubber blocks 17 into multiple independent small pieces, preventing the rubber blocks 17 from adsorbing together and being unfavorable for removing the coloring layer 13, or leaving large imprints on the reflective film after removal and being unfavorable for cleaning and affecting the use of the lens;

[0026] The lower surface of the adhesive layer 6 is fixedly connected to the intermediate layer 5, the lower surface of the intermediate layer 5 is fixedly connected to the support layer 4, the lower surface of the support layer 4 is fixedly connected to the bottom lining layer 3. The thicknesses of the intermediate layer 5, the support layer 4 and the bottom lining layer 3 are all the same. The thickness of the intermediate layer 5, the support layer 4 and the bottom lining layer 3 is 0.4 - 1.0 mm. The intermediate layer 3, the support layer 4 and the bottom lining layer 5 are all made of photochromic materials, which can make the reflective film have good visibility, can reflect light, and can change color when irradiated by light at night. The lower surface of the bottom lining layer 3 is fixedly connected to the adhesive layer 2, so that the reflective film can be pasted on the lens. The lower surface of the adhesive layer 2 is fixedly connected to the backing paper 1 to prevent the adhesive layer 2 from being damaged before the reflective film is used, which may affect the adsorption function of the reflective film.

[0027] Working principle: Before use, cut the reflective film according to the shape of the lens, then tear off the backing paper 1, align the adhesive layer 2 with the lens, and paste the reflective film on the lens. When light irradiates, since the base wall 14 is hexagonal, the base layer 7 has the characteristics of multiple reflection surfaces, providing a good reflection effect. At the same time, the glass microspheres 15 in the reflective layer 8 improve the reflective effect of the reflective film and also enhance the heat insulation effect. The ceramic carrier 10 is provided in the ceramic layer 9, so that the reflective film has a certain hardness to protect the reflective film from being easily pierced and damaged to the lens. The heat insulation layer 11 also improves the heat resistance of the reflective film. The wear-resistant particles 12 provided on the surface will also come into contact with external objects first, reducing the wear of the reflective layer 8 and affecting the various functions of the reflective film. The coloring layer 13 makes the reflective film have different colors when light irradiates the reflective film, and at the same time reduces the influence of direct sunlight on the functions of the reflective film during use.

[0028] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
