[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] Combination Figures 1 to 6 According to an embodiment of the present invention, the laser curtain 1000 includes a fabric layer 100 and a laser-treated laser layer 200. The laser layer 200 is laid on the surface of the fabric layer 100. The laser layer 200 and the fabric layer 100 are respectively formed and connected. The laser layer 200 includes a reflective surface 220, which faces away from the fabric layer 100 and is adapted to reflect light from the side of the laser layer 200 facing away from the fabric layer 100.

[0029] Specifically, the fabric layer 100 of the laser curtain 1000 can be located on the side facing indoors, and the laser layer 200 can be located on the side facing outdoors. In this way, indoors, the fabric layer 100 allows the laser curtain 1000 to use the same fabric as a regular curtain, thus providing both comfort and aesthetics. However, on the outdoor side, the laser curtain 1000 has a laser layer 200 for reflecting light, which reduces light entering the room and helps lower the indoor temperature. Therefore, the laser curtain 1000 of this embodiment can simultaneously provide both the comfort of using a laser curtain and the effect of reflecting sunlight.

[0030] According to an embodiment of the present invention, the laser curtain 1000, by providing a laser layer 200 on one side of the laser curtain 1000, can ensure the comfort and aesthetics of the laser curtain 1000, while also having the effect of reflecting light, reducing sunlight entering through the curtain, and helping to lower the indoor temperature. In other words, according to an embodiment of the present invention, the laser curtain 1000, by providing a laser layer 200 on one side of the curtain surface, forms a laser curtain 1000 with a laser effect, which can produce optical effects only on the reverse side of the curtain, while the light transmission or decorative effect on the front remains undisturbed.

[0031] Combination Figure 4 and Figure 6 In some embodiments of this utility model, the laser layer 200 includes a reflective surface 220, which is disposed on the side of the laser layer 200 facing away from the fabric layer 100. The reflective surface 220 is configured as an uneven surface. Specifically, the uneven surface can controllably scatter or directionally adjust the light, so that when light shines on the reflective surface 220, the uneven structure on the reflective surface 220 can reflect the light, thereby reducing the possibility of sunlight directly passing through the laser curtain 1000 and entering the room. This allows users to reduce sunlight entering the room when using the laser curtain 1000, which helps to lower the indoor temperature.

[0032] Furthermore, combined Figure 4 In some embodiments of this invention, the laser layer 200 further includes a substrate layer 210. At least a portion of the surface of the substrate layer 210 facing away from the fabric layer 100 is configured as a reflective surface 220. The reflective surface 220 is formed on the surface of the substrate layer 210 by spraying, embossing, or laser engraving. Specifically, when manufacturing the laser layer 200, the substrate layer 210 can be treated to form a reflective surface 220 that can achieve a reflective effect. For example, when manufacturing the laser layer 200, powder can be directly sprayed onto the substrate layer 210 using laser equipment to form a film-like structure, thereby improving the reflective effect. Alternatively, the reflective surface 220 can be formed by embossing on the substrate layer 210 using a roll forming device, or it can be constructed by laser engraving on the substrate layer 210.

[0033] Furthermore, combining Figure 4 and Figure 6In some embodiments of this invention, the reflective surface 220 includes a protrusion 230, which is configured as a cone that gradually tapers away from the fabric layer 100. This cone-shaped structure of the protrusion 230 forms multiple inclined, extending reflective surfaces. When sunlight shines on the reflective surface 220, it can be refracted by the reflective surfaces on the protrusion 230. The protrusion 230 can be a multi-faceted pyramid, so that each protrusion 230 has multiple reflective surfaces, which helps to improve the reflective effect. Furthermore, the cone-shaped protrusion 230 can reduce stress concentration and improve the structural stability of the protrusion 230, thereby helping to maintain the reflective effect of the laser layer 200.

[0034] In practical applications, the laser path can be controlled by a computer to form periodic or randomly distributed microstructures. The multiple protrusions 230 of the reflective surface 220 can produce rainbow colors or dynamic light spot effects when light is refracted.

[0035] It should be noted that the protrusion 230 can be a micrometer-scale structure, enabling optical control effects. It is usually invisible to the naked eye, but under certain conditions it can produce a reflective effect, thus combining aesthetics and functionality. Figure 1 and Figure 5 The surface of the laser layer 200, as seen by the user, can be relatively flat. More specifically, by evenly arranging multiple protrusions 230 on the reflective surface 220, the reflected light can form a continuous visual effect, and the laser layer 200 can appear to be smooth.

[0036] In some embodiments of this invention, the reflective surface 220 includes concentric circle patterns, spiral patterns, or geometric shapes. Through specific pattern design, light changes with angle to present dynamic visual effects (such as rainbow gradients or flowing light spots). Specifically, micron-level uneven structures (such as concentric circles, spiral patterns, or geometric shapes) can be formed on the surface of the reflective surface 220 by laser engraving or burning.

[0037] In some embodiments of this invention, the laser layer 200 is configured with a wavelength of 1064nm or 532nm and a power density of 30–200W / cm². 2 Furthermore, the laser-processed film layer requires a scanning speed greater than or equal to 0.5 m / s and less than or equal to 5 m / s. Specifically, during the fabrication of the laser layer 200, the substrate layer 210 can undergo surface cleaning and anti-static treatment to ensure the stability of the laser processing. The laser parameters are set to a laser wavelength of 1064 nm (infrared laser) or 532 nm (green laser), and a power density of 30–200 W / cm². 2 The scanning speed is 0.5 to 5 m / s, and the focal length is adjusted to ensure that the laser focus is precisely applied to the reflective surface 220.

[0038] Preferably, the power density is also set to 50–150 W / cm². 2 .

[0039] In some embodiments of this invention, the thickness of the fabric layer 100 is greater than the thickness of the laser layer 200. The greater thickness of the fabric layer 100 enhances its support, facilitating the connection of the laser layer 200 to it and improving the structural stability of the connected laser layer 200. Furthermore, the thickness of the fabric layer 100 also improves the drape and light-blocking effect of the laser curtain 1000.

[0040] Optionally, the thickness of the laser layer 200 is greater than or equal to 5 mm and less than or equal to 50 mm. Specifically, a thicker laser layer 200 can enhance the light reflection effect, but an excessively thick laser layer 200 can result in a bulky overall structure for the laser curtain 1000. Therefore, by limiting the thickness of the laser layer 200 to a certain range, both the reflective effect of the laser layer 200 and the aesthetics and overall structural consistency of the laser curtain 1000 can be guaranteed. For example, the thickness of the laser layer 200 can be 5 mm, 10 mm, 20 mm, or 30 mm. This can be specifically set according to the user's usage scenario.

[0041] In some embodiments of this utility model, the laser layer 200 is a coating or film to facilitate manufacturing and ensure the structural stability of the laser layer 200.

[0042] In some embodiments of this utility model, the fabric layer 100 is a fiber fabric. Specifically, the fiber fabric is durable, has good wrinkle and shrinkage resistance, which helps to improve the durability and aesthetics of the laser curtain 1000. In addition, the high-density fiber fabric can improve the light-blocking effect of the laser curtain 1000. Furthermore, the fiber fabric also has a certain degree of UV protection.

[0043] Therefore, the laser curtain 1000 of this utility model embodiment can maintain the fabric material or texture pattern of the laser curtain 1000 on the front side of the laser curtain 1000, that is, the side facing the user or the side facing the room, while a laser layer 200 that can reflect light is formed on the back side or the reverse side of the laser curtain 1000, that is, the side away from the user or the side facing the outside. This improves the reflection of light and increases the color variation, thereby improving the aesthetics and practicality of the laser curtain 1000.

[0044] For example, the fabric layer 100 can be made of synthetic fiber fabric with high light transmittance and laser resistance (such as polyester fiber, nylon, etc.) to make the laser curtains have light transmittance and reflective properties, and also improve the overall structural consistency and aesthetics of the laser curtains.

[0045] Combination Figure 2and Figure 4 In some embodiments of this utility model, the laser curtain 1000 further includes an adhesive layer 300, which is disposed between the fabric layer 100 and the laser layer 200, and adheres the laser layer 200 to one side surface of the fabric layer 100. Specifically, the adhesive layer 300 can be a medium such as glue used for bonding between the laser layer 200 and the fabric layer 100, forming an adhesive layer that achieves a bonding effect between the laser layer 200 and the fabric layer 100. During processing and manufacturing, the fabric layer 100 can be pre-treated, such as by cleaning and removing dust. Then, hot melt adhesive or reactive adhesive or glue can be applied to the opposite side of the fabric layer 100 and / or the laser layer 200. The laser layer 200 and the fabric layer 100 can be directly connected by high-temperature lamination, that is, by high-temperature lamination, such as using a laminating machine and applying pressure, the laser layer 200 is attached to the fabric layer 100.

[0046] The adhesive layer 300 can also be an intermediate layer stacked between the fabric layer 100 and the laser layer 200. The adhesive layer 300 is used to fix the fabric layer 100 and the laser layer 200 to their respective opposite sides by high-temperature heating, facilitating manufacturing and resulting in high bonding strength. Specifically, during processing, the fabric layer 100 can be pre-treated, such as by cleaning and removing dust. Then, hot melt adhesive or reactive adhesive or glue is applied to one side of the fabric layer 100 and the laser layer 200 and / or the respective sides of the adhesive layer 300. A laminating machine is then used, and pressure is applied, to bond the laser layer 200 and the fabric layer 100 to the adhesive layer 300.

[0047] Optionally, at least one of the opposite sides of the adhesive layer 300 has an adhesive surface, to which the laser layer 200 is adhered, and the other side of the adhesive layer 300 is laid on one side surface of the fabric layer 100. Specifically, the adhesive layer 300 enables the connection between the laser layer 200 and the fabric layer 100, facilitating the assembly of the laser curtain 1000. Specifically, if the laser layer 200 is directly placed on the fabric layer 100, it may cause damage to the fabric layer 100. By setting the adhesive layer 300, the fabric layer 100 and the laser layer 200 can be formed separately, and the separately formed fabric layer 100 and laser layer 200 are connected by the adhesive layer 300, which facilitates manufacturing and assembly and improves the finished product effect.

[0048] More specifically, the adhesive layer 300 may have an adhesive surface on one of the two opposite sides, or it may have adhesive surfaces on both opposite sides.

[0049] For example, combining Figure 4The adhesive layer 300 includes a first adhesive surface 310 and a second adhesive surface 320 disposed opposite to each other. The laser layer 200 is bonded to the first adhesive surface 310. The fabric layer 100 is bonded to the second adhesive surface 320 of the adhesive layer 300, which can improve the stability of the connection between the laser layer 200 and the fabric layer 100 and improve the overall effect of the laser curtain 1000. Optionally, the second adhesive surface 320 and the fabric layer 100 can be fixedly bonded, for example, in a way that is not easy to separate after bonding, i.e., the user cannot repeatedly disassemble and reassemble it. Alternatively, the second adhesive surface 320 and the fabric layer 100 can be bonded by Velcro, thereby enabling the adhesive layer 300 to be disassembled and reassembled, which is convenient for users to use flexibly, such as removing the adhesive layer 300 and the laser layer 200 to clean the fabric layer 100.

[0050] In some embodiments of this invention, the adhesive layer 300 may include an adhesive surface and a connecting surface disposed opposite to each other. The laser layer 200 is laid and bonded to the adhesive surface, and the connecting surface is laminated and bonded to the fabric layer 100. That is, on opposite sides of the adhesive surface, one side is the adhesive surface, and the laser layer 200 is bonded to the adhesive surface to fix the laser layer 200 to the adhesive layer 300. The other side of the adhesive layer 300 is a connecting surface for bonding with the fabric layer 100. The connecting surface is laid on the surface of the fabric layer 100 so that the laser layer 200 can be bonded to the fabric layer 100 through the adhesive layer 300. Specifically, the adhesive layer 300 may be sewn onto the fabric layer 100 so that the adhesive layer 300 can be connected to the fabric layer 100. Alternatively, the connecting surface may have mounting buckles or Velcro positioned opposite to the fabric layer 100. In this way, the adhesive layer 300 can be detachably connected to the fabric layer 100. Thus, when the laser layer 200 is needed, the user can connect the adhesive layer 300 with the laser layer 200 attached to it to the fabric layer 100, and when the laser layer 200 is not needed, the adhesive layer 300 can be removed from the fabric layer 100, thereby separating the laser layer 200 from the fabric layer 100, which improves the flexibility of use.

[0051] In some embodiments of this utility model, the laser curtain 1000 further includes a protective layer. The protective layer is laid on the outer surface of the laser layer 200, and at least a portion of the protective layer is laid on the side of the laser layer 200 facing away from the fabric layer 100. The protective layer is a light-transmitting coating or film. Laying the protective layer on the surface of the laser layer 200 protects the laser layer 200 and prevents wear during transportation or use, thus affecting the reflective effect of the laser layer 200. Specifically, a transparent UV-curable coating or film can be applied to the surface of the laser layer 200 to prevent oxidation or wear while maintaining the light transmittance of the laser.

[0052] Furthermore, when the fabric layer 100 of the laser curtain 1000 is a non-light-blocking fabric, in order to improve the light-blocking effect of the laser curtain 1000, in some embodiments of this utility model, the laser curtain 1000 may also include a light-blocking layer, which is disposed between the fabric layer 100 and the laser layer 200, thereby improving the light-blocking effect of the laser curtain 1000. Specifically, a black coating or film can be applied between the laser layer 200 and the surface layer to increase the overall light-blocking properties of the fabric.

[0053] Alternatively, the light-blocking effect can be achieved by setting laser layers 200 with different light transmittance. Specifically, when the laser layer 200 is a high-reflectivity laser layer, the laser curtain 1000 has a high light-blocking effect. The surface of the laser layer 200 is covered with a metal coating (such as aluminum or silver), and a holographic pattern is formed by laser engraving, giving it a strong reflective effect and making it almost opaque, with light being reflected rather than transmitted. When the laser layer 200 is a semi-transparent laser layer, partial light transmission can be achieved. For example, an extremely thin metal coating or transparent medium combined with microstructures can be used, allowing the laser layer 200 to reflect some light while allowing some light to pass through (transmittance of approximately 30%-70%). When the laser layer 200 is a holographic transparent laser layer, a high light transmittance effect can be achieved, i.e., there is no metal coating, and only microstructures are engraved on a transparent film (such as acrylic), so that the laser layer 200 has high light transmittance (transmittance >80%). A holographic effect is displayed when light shines directly on it, and it is nearly transparent when there is no light. Users can choose based on their actual usage scenarios or needs.

[0054] The following describes a specific embodiment of the laser curtain 1000 of this utility model with reference to the accompanying drawings.

[0055] Combination Figures 1 to 6 According to the embodiment of the present utility model, the laser curtain 1000 is formed by combining the curtain fabric layer 100 with the reflective laser layer 200. By using laser technology to form a specific optical structure on the reverse side of the fabric, a dynamic laser refraction effect is produced when light shines on the laser curtain 1000, while the front side of the laser curtain 1000 maintains the conventional fabric decorative texture.

[0056] Specifically, the laser curtain 1000 includes: a fabric layer 100 and a laser layer 200 located on its back, and a reflective surface 220 with microstructures formed on the surface of the laser layer 200 by laser processing. The manufacturing process of the laser curtain 1000 includes the following steps: pre-treatment of the fabric layer 100; bonding the laser layer 200 to the fabric layer 100 using an adhesive layer 300; and laser engraving the reflective surface 220 on the substrate layer 210 of the laser layer 200, wherein the laser parameters are a wavelength of 1064 nm and a power density of 50–150 W / cm². 2Finally, a protective layer is applied to the surface of the laser layer 200 after further processing. Alternatively, the laser layer 200 can be manufactured separately and then bonded to the back of the fabric layer 100 using an adhesive layer 300.

[0057] The laser curtain 1000 according to this utility model embodiment has the characteristics of simple process, low manufacturing cost, and the laser layer 200 is not easy to fall off. Under sunlight or lamplight, the reverse side of the laser curtain 1000 displays a uniform rainbow-colored light spot, and the light transmittance of the front side is less than or equal to 95%, which can play a role in blocking light. The laser curtain 1000 of this utility model embodiment can play a dual role of sun protection and light blocking in summer.
