Description

Technical Field

[0001] This utility model relates to the field of glass technology, specifically to a high-transmittance glass structure. Background Technology

[0002] In many fields such as architecture, optical instruments, and automobile manufacturing, glass is an indispensable material, and its light transmittance has always been a key indicator that has received much attention. In the current technology, the light transmittance of glass is limited by the material composition and surface coating process.

[0003] Traditional glass has a high iron content, which leads to enhanced absorption of green and violet-red wavelengths in visible light. Its light transmittance is generally less than 90%, resulting in poor light transmission and affecting indoor lighting conditions. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a high-transmittance glass structure that significantly improves light transmittance.

[0006] II. Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a high-transmittance glass structure, including a glass substrate, and further including: an interference film disposed on the top of the glass substrate for eliminating a certain proportion of visible light reflection, an ETFE film disposed on the top of the interference film, and a plurality of dielectric films disposed on the top of the ETFE film for reducing the reflectivity of visible light, and a self-cleaning coating disposed on the top of the dielectric film and the bottom of the glass substrate for reducing stain adhesion and maintaining high light transmittance.

[0008] As an improvement, the interference film is made of magnesium fluoride and has a thickness of 50-100 nanometers.

[0009] As an improvement, the dielectric film is designed to have 3-5 layers, and the dielectric film is made of silicon dioxide or titanium dioxide.

[0010] As an improvement, the thickness of the ETFE film is 50-200 micrometers.

[0011] As an improvement, the self-cleaning coating is made of a superhydrophobic material.

[0012] As an improvement, the glass substrate is high borosilicate glass or ultra-clear glass.

[0013] III. Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. By using interference films, ETFE films, and dielectric films, the surface of the glass substrate can be treated to reduce light reflectivity and maintain high light transmittance over a long period of time.

[0016] 2. Because the glass substrate is high borosilicate glass, it has an extremely low coefficient of thermal expansion and high light transmittance. With the help of the self-cleaning coating, it reduces the adhesion of stains and maintains high light transmittance for a long time. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 2 and attached Figure 3A high-transmittance glass structure includes a glass substrate 1, characterized in that it further includes: an interference film 2 disposed at the top of the glass substrate 1 for eliminating a certain proportion of visible light reflection; an ETFE film 3 disposed at the top of the interference film 2; a plurality of dielectric films 4 disposed at the top of the ETFE film 3 for reducing the reflectivity of visible light; and a self-cleaning coating 5 disposed at the top of the dielectric films 4 and the bottom of the glass substrate 1 for reducing stain adhesion and maintaining high light transmittance.

[0024] Combined with appendix Figure 3 The interference film 2 is made of magnesium fluoride and has a thickness of 50-100 nanometers. It uses destructive interference to reduce reflected light and further enhance the intensity of transmitted light.

[0025] Combined with appendix Figure 3 The dielectric film 4 is designed to have 3-5 layers. The dielectric film 4 is made of silicon dioxide or titanium dioxide, which greatly reduces the reflectivity of visible light and maintains high light transmittance.

[0026] Combined with appendix Figure 3 The ETFE film 3 has a thickness of 50-200 micrometers and provides mechanical support for the overall glass, improving its durability.

[0027] Combined with appendix Figure 3 The self-cleaning coating 5 is made of superhydrophobic material, which makes water droplets easy to slide off, reduces stain adhesion, and maintains high light transmittance for a long time.

[0028] Combined with appendix Figure 1 The glass substrate 1 is high borosilicate glass or ultra-white glass, which has an extremely low coefficient of thermal expansion and high light transmittance, and is resistant to high temperature and thermal shock, thereby reducing light loss from the source.

[0029] In specific implementation of this utility model:

[0030] First, high borosilicate glass was selected as the material for the glass substrate 1. High borosilicate glass has an extremely low coefficient of thermal expansion and high light transmittance, which allows it to maintain stable physical properties even at high temperatures, effectively resisting thermal shock and reducing light loss during propagation from the source.

[0031] Next, the interference film 2 is made of magnesium fluoride, which has excellent optical properties and can effectively reduce reflected light by utilizing the principle of destructive interference, further increasing the intensity of transmitted light. Combined with the ETFE film 3, which has a transmittance of over 95%, and the dielectric film 4, designed with 3-5 layers, the multilayer dielectric film design further reduces visible light reflectance while maintaining high transmittance, significantly improving the overall transmittance.

[0032] Meanwhile, a self-cleaning coating 5 is provided at the top of the dielectric film 4 and the bottom of the glass substrate 1. The self-cleaning coating 5 is made of superhydrophobic material. Superhydrophobic material has extremely low surface energy, which makes water droplets easy to slide off its surface, thereby reducing the adhesion of stains and maintaining the high light transmittance of the glass for a long time.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
