[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] 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 at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0026] like Figure 1 As shown, this utility model embodiment provides a color-tunable glass curtain wall, including a glass substrate 1 and a color-changing layer. The color-changing layer is embedded in the glass substrate 1 and includes at least one dimming film 2, which contains a dye liquid crystal.

[0027] The glass substrate 1 serves as the basic load-bearing structure of the curtain wall. It is made of high-strength, stable tempered glass or laminated glass, and its size can be customized according to the actual curtain wall installation requirements.

[0028] It should be noted that dye-based liquid crystals are materials in which specific dyes are added to liquid crystals to modulate the absorption, scattering, and polarization properties of light, thereby changing color and optical properties. In this invention, the dye-based liquid crystal can specifically be anzo dye liquid crystal, anthraquinone dye liquid crystal, or cyanine dye liquid crystal, etc.

[0029] When different electric fields are applied to the dimming film 2, the dye liquid crystal molecules within the film 2 undergo orientation changes, thereby altering the light transmittance and color of the film 2 and achieving the color-tuning function of the glass curtain wall. For example, during strong sunlight in the daytime, increasing the electric field strength alters the arrangement of the dye liquid crystal molecules, causing the color of the dimming film 2 to darken, reducing the light transmittance of the glass curtain wall, decreasing indoor heat entry and glare, and providing good heat insulation and sun shading effects; while in insufficient light, decreasing the electric field strength causes the color of the dimming film 2 to lighten, increasing the light transmittance and enhancing indoor lighting.

[0030] When the color-changing layer includes multiple dimming films 2, the multiple dimming films 2 are stacked. In a specific implementation, taking a two-layer dimming film 2 as an example, the first dimming film 2 and the second dimming film 2 are stacked sequentially from the inside out. Adjacent dimming film layers 2 are fixed together by an adhesive 3, preferably PVB adhesive.

[0031] In practical applications, such as Figure 1As shown, a layer of PVB adhesive is first evenly applied to the upper surface of the first dimming film 2. Then, the second dimming film 2 is accurately placed on top of the first dimming film 2 coated with PVB adhesive. The PVB adhesive is then cured by heating and pressurizing, achieving a firm connection between the two dimming films 2. Furthermore, the first dimming film 2 and the second dimming film 2 are also fixed to the two glass substrates 1 using PVB adhesive.

[0032] In the multi-layered dimming film 2, adjacent layers of dimming film 2 have different colors; for example, the first dimming film 2 is light blue, and the second dimming film 2 is light green. Under different electric fields, the light transmittance of each layer of dimming film 2 changes, and the different colors overlap and mix, producing a richer and more diverse range of color variations to meet the personalized color requirements of glass curtain walls in different scenarios. At the same time, all dimming films 2 are of the same size, ensuring the regularity and stability of the overall structure after stacking, facilitating installation into the glass substrate 1.

[0033] In one embodiment, LED beads are disposed on the surface of the color-changing layer. These LED beads are characterized by low energy consumption, long lifespan, and high brightness. For example, when used in the exterior decoration of commercial buildings, the LED beads can be controlled to turn on and off and change color at night, in conjunction with the color of the dimming film 2, to create a dazzling and colorful lighting effect, enhancing the building's aesthetics and attractiveness. The LED beads are connected to an external power supply and control circuit via wires. The control circuit can achieve precise control of the LED beads according to a preset program or external commands.

[0034] In one embodiment, the tinted glass curtain wall further includes a protective layer disposed between the glass substrate 1 and the color-changing layer. The protective layer is preferably a transparent protective film. The transparent protective film can be made of PET material, which has good light transmittance, abrasion resistance, and scratch resistance. During installation, the transparent protective film is first cut to a suitable size and then pasted between the glass substrate 1 and the color-changing layer. This effectively protects the dimming film 2 and LED components in the color-changing layer, preventing damage during transportation, installation, and use, thus extending the service life of the glass curtain wall without affecting its light transmittance and color-changing effect.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
