Description

Technical Field

[0001] This utility model relates to the field of skylights, skylights, and lighting technology, specifically a flexible diffuse reflection light-enhancing soft film light guide wall. Background Technology

[0002] North-facing rooms receive very little natural light throughout the year. In winter, when sunlight is weak, the roof is cold and damp. According to data, the winter illuminance is only 10% to 15% of that of south-facing rooms. At the same time, underground buildings or poorly lit, cold places have no angle to allow direct sunlight to enter the room. The measured illuminance of underground buildings, semi-underground spaces and light wells is generally below 50 lx, far below the minimum requirement of 75 lx for residential living rooms in GB 50033-2013 "Standard for Daylighting Design of Buildings".

[0003] The existing technical solution still has the following problems when used: Currently, most conventional skylights have painted walls, resulting in poor light reflection efficiency, with a reflectivity of only about 20% to 25%. Due to the directional nature of light, even with large skylights, the lighting efficiency remains low; light directly hitting the walls is absorbed, leaving very little reflected light to reach the room. While metal mirror reflectors (such as mirrored aluminum or stainless steel) can achieve a reflectivity of up to 80%, they suffer from drawbacks such as glare, hot spots, and oxidation-induced loss of gloss. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an elastic diffuse reflection light-enhancing soft film light guide wall to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elastic diffuse reflection light-enhancing soft film light guide wall, comprising: a wall and a skylight installed on the top surface of the wall, wherein a base plate is connected to the surface of the wall, a high-reflectivity light guide soft film is connected to the surface of the base plate, and mounting strips are connected to both ends of the high-reflectivity light guide soft film; The base plate has a mounting groove at one end near the mounting strip. A clamping spring is connected to the inner wall of the opening of the base plate near the mounting groove. A linkage plate is connected to the other end of the clamping spring. An adjusting push plate is connected to the surface of the linkage plate. A clamping plate is connected to the side of the linkage plate opposite to the clamping spring. Preferably, the high-reflectivity light-guiding film is fitted and connected to the mounting grooves at both ends of the base plate via mounting strips.

[0006] Preferably, the clamping spring and the linkage plate form an elastic linkage structure, and the linkage plate and the adjusting push plate are an integral structure.

[0007] Preferably, one end of the clamping plate relative to the linkage plate passes through and extends into the inner side of the mounting groove, and the clamping plate is in contact with the mounting strip.

[0008] Preferably, the bottom surface of the skylight is connected to a fixed frame, the inner side of the fixed frame is connected to a panel, the inner side of the panel is connected to a louver, the end of the louver near the panel is connected to a pivot, the inner wall of the opening of the panel is connected to a buckle, and the surface of the pivot near the buckle is provided with a slot.

[0009] Preferably, the high-reflectivity light-guiding film is made of a fluorocarbon coating, a high-diffuse-reflection layer, a flexible PET substrate, and a flame-retardant pressure-sensitive adhesive layer.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention involves embedding the mounting strips at both ends of the high-reflectivity light-guiding film into the mounting grooves at both ends of the base plate. Simultaneously, pushing the adjusting plate causes the linkage plate to move at the top opening of the base plate, which in turn compresses the clamping spring. Due to the elasticity of the clamping spring, the clamping plate on one side of the linkage plate locks and fixes the mounting strips, ensuring that the high-reflectivity light-guiding film is laid flat on the base plate. When sunlight shines through the skylight, the light is refracted behind the high-reflectivity light-guiding film and then refracted into the living room, effectively increasing the light intensity brought into the room by the skylight or atrium.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please refer to Figures 1-7. This utility model provides a technical solution: an elastic diffuse reflection light-enhancing soft film light guide wall, including: a wall 1 and a skylight 2 installed on the top surface of the wall 1. A base plate 3 is connected to the surface of the wall 1, and a high-reflection light guide soft film 4 is connected to the surface of the base plate 3. Both ends of the high-reflection light guide soft film 4 are connected to mounting strips 5. The base plate 3 has an installation groove 6 at one end near the mounting strip 5. A clamping spring 7 is connected to the inner wall of the opening of the base plate 3 near the mounting groove 6. A linkage plate 8 is connected to the other end of the clamping spring 7. An adjusting push plate 9 is connected to the surface of the linkage plate 8. A clamping plate 10 is connected to the side of the linkage plate 8 opposite to the clamping spring 7. The high-reflection light guiding film 4 is fitted and connected to the mounting grooves 6 at both ends of the base plate 3 through the mounting strip 5. The clamping spring 7 and the linkage plate 8 form an elastic linkage structure. The linkage plate 8 and the adjusting push plate 9 are an integral structure. The end of the clamping plate 10 opposite to the linkage plate 8 passes through and extends to the inner side of the mounting groove 6. The clamping plate 10 is in contact with the mounting strip 5. A fixed frame 11 is connected to the bottom surface of the skylight 2. A panel 12 is connected to the inner side of the fixed frame 11. A louver 13 is connected to the inner side of the panel 12. A pivot 14 is connected to one end of the louver 13 near the panel 12. A buckle 15 is connected to the inner wall of the opening of the panel 12. A slot 16 is opened on the surface of the pivot 14 near the buckle 15. By rotating the pivot 14 at one end of the louver 13 along the opening on one side of the panel 12, it is convenient to drive the louver 13 to adjust its angle. At this time, it is convenient to adjust the angle of the louver 13 on the bottom surface of the skylight 2. At this time, the angle adjustment of the louver 13 is linked with the high-reflection light guide film 4. The incident light is controlled by the angle of the louver 13 to avoid excessive reflected light caused by strong midday light.

[0015] The high-reflectivity light-guiding film 4 is made of a fluorocarbon coating 41, a high diffuse reflection layer 42, a flexible PET substrate 43, and a flame-retardant pressure-sensitive adhesive layer 44. The first layer, the fluorocarbon coating 41, has a thickness of 8 μm to 12 μm, which improves weather resistance and controls the yellowing index ΔYI≤2, ASTM E313, 1000 h UV-B. The second layer, the high diffuse reflection layer 42, contains flake-shaped titanium dioxide and barium sulfate composite particles with an average particle size of 0.3 μm to 0.5 μm, a volume concentration of 45%, a visible light reflectance ≥92%, and a haze ≥80%, eliminating specular glare. The third layer, the flexible PET substrate 43, has a tensile strength ≥200 MPa and an elongation at break ≥100%, ensuring conformal adhesion to the wall surface. The fourth layer, the flame-retardant pressure-sensitive adhesive layer 44, uses a halogen-free flame-retardant acrylic system.

[0016] Working principle: When using the elastic diffuse reflection light-enhancing soft film light guide wall, firstly, the mounting strips 5 at both ends of the high-reflectivity light guide soft film 4 are fitted into the mounting grooves 6 at both ends of the base plate 3. At the same time, the adjusting push plate 9 is pushed, which drives the linkage plate 8 to move at the top opening of the base plate 3. Simultaneously, the linkage plate 8 compresses the clamping spring 7. At this time, due to the elastic structure of the clamping spring 7 itself, the clamping plate 10 on one side of the linkage plate 8 locks and fixes the mounting strips 5, ensuring that the high-reflectivity light guide soft film 4 is laid flat on the base plate 3. When the skylight 2 shines light, the light is refracted behind the high-reflectivity light guide soft film 4 and then refracted to the living room position, which can effectively improve the light intensity brought into the room by the skylight 2 and the skylight. At the same time, the traditional adhesive method is abandoned, and a quick disassembly and assembly method is adopted, which makes it easy to disassemble the high-reflectivity light guide soft film 4 for surface cleaning and cleaning, avoiding dust from reducing the reflectivity.

[0017] This is the characteristic of the flexible diffuse reflection light-enhancing soft film light guide wall. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0018] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
