Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically a window skylight with a deformable reflective curved surface structure. Background Technology

[0002] Currently, window lights that mimic a "blue sky effect" primarily rely on high-cost Rayleigh diffuser materials. These diffusers, illuminated by a light source, use Rayleigh scattering to create a visual experience similar to a clear sky on the panel. However, these devices are typically bulky and expensive, making it difficult to meet diverse needs regarding product thickness, cost, and installation compatibility. Furthermore, to enhance the realism and layering of the light fixture's frame, some products attempt to create a "pseudo-reflective bright edge" effect using mirror reflection to simulate the bright areas around a window under natural light. However, because mirror reflection is highly sensitive to viewing angles, the bright edge effect is unstable and unnatural. It also often results in "light bead transmission" due to direct illumination from the LED beads, creating noticeable light spots or a grainy appearance, severely impacting visual uniformity and aesthetics. Therefore, achieving a realistic and natural blue sky effect and a stable, uniform pseudo-reflective bright edge effect within a thinner structure without relying on high-cost Rayleigh diffuser materials has become a key technological challenge for the upgrading of this type of product. Utility Model Content

[0003] The purpose of this invention is to provide a window skylight with a deformable reflective curved surface structure, so as to achieve a realistic and natural blue sky light effect and a stable and uniform pseudo-reflective bright edge effect in a thin structure without relying on high-cost Rayleigh diffusion materials.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a window skylight with a deformable reflective curved surface structure, comprising:

[0005] The faceplate has its internal space divided into an upper accommodating area and a lower accommodating area;

[0006] The blue sky light effect module, located in the upper accommodating area, includes:

[0007] A side-mounted blue LED array, the blue LED array comprising combinations of LEDs with different color temperatures;

[0008] The light guide component receives the lateral light from the blue LED array and converts it into uniform forward light emission;

[0009] The pseudo-reflective bright edge module, disposed in the lower receiving area, includes:

[0010] A bright edge light source is disposed inside the edge of the face frame;

[0011] A deformable reflective sheet, the two sides of which are pressed by the face frame groove to form an arc-shaped reflective surface, and is located above the bright edge light source;

[0012] A fogging cover is tilted to cover the outside of the deformable reflective sheet and scatters reflected light from the bright edge light source.

[0013] In one feasible implementation, the blue LED array includes: a first group of LEDs emitting blue light in a first wavelength band; a second group of LEDs emitting blue light in a second wavelength band; and the first group of LEDs and the second group of LEDs are arranged at intervals according to a preset ratio.

[0014] In one feasible implementation, the light guide assembly includes: a light guide plate whose light-incident end face receives light from a blue LED array; a diffuser plate located on the light-outcrystal side of the light guide plate; and a microstructure inside the light guide plate that causes the light to be redirected by 90°.

[0015] In one feasible implementation, the deformable reflective sheet is a PET specular reflective film, whose arc-shaped reflective surface converts point light source light into wide-angle diffused light.

[0016] In one feasible implementation, the tilt angle of the atomizing side cover is 30°-60°, and the inner surface is provided with scattering microstructures.

[0017] In one feasible implementation, the face frame includes a replaceable mounting structure, which is selected from at least one of the following mounting structures: a spring clip provided on the side wall, a magnetic module provided on the back, and an aluminum buckle plate joint groove provided on the top.

[0018] In one feasible implementation, the window skylight with a deformable reflective surface structure further includes a buffer pad disposed above the blue sky light effect module, and a back cover located at the top of the face frame.

The blue sky light effect module uses a specially tuned color temperature blue LED array arranged in a preset ratio and interval, combined with a light guide plate and a diffuser plate to form a composite spectrum mixing mechanism, which not only achieves the feeling of clear sky light, but also significantly reduces the thickness through side light guiding and forward light emission structures; the pseudo-reflective bright edge module uses a bright edge light source set at the edge of the frame, combined with the curved surface reflection of a deformable reflective sheet made of PET mirror reflective film, and further diffuses the light through tilt angle optimization and internal microstructure scattering of the atomized edge cover, thereby creating a natural, soft and grain-free bright edge light band, completely eliminating the problems of "transparent LED beads" and local high brightness. It provides effective support for future highly integrated architectural lighting and has significant technological innovation value and industrialization prospects. Attached Figure Description

[0028] 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.

[0029] Please see Figures 1 to 7 This utility model provides a technical solution: a window skylight with a deformable reflective curved surface structure, including: a face frame 1, a blue sky light effect module 3, a side-mounted blue LED array 31, a light guide component 32, a pseudo-reflective bright edge module 2, a bright edge light source 21, a fogging edge cover 22, and a deformable reflective sheet 23.

[0030] Specifically, the internal space of the face frame 1 is divided into an upper receiving area and a lower receiving area; the blue sky light effect module 3 is set in the upper receiving area, which includes a side-mounted blue LED array 31, which contains LED combinations of different color temperatures; the light guide component 32 receives the side light from the blue LED array 31 and converts it into forward uniform light output;

[0031] The pseudo-reflective bright edge module 2 is located in the lower receiving area and includes: a bright edge light source 21 located inside the edge of the face frame; a deformable reflective sheet 23 whose two sides are squeezed by the slot of the face frame 1 to form an arc-shaped reflective surface and located above the bright edge light source 21; and a fogging cover 22 obliquely covering the outside of the deformable reflective sheet 23 and scattering the reflected light from the bright edge light source 21.

[0032] The window skylight with a deformable reflective curved surface structure provided in this application achieves an ultra-thin blue sky light effect and a uniform pseudo-reflective bright edge through structural innovation. The partitioned design of the frame 1 independently arranges the blue sky light effect module 3 and the pseudo-reflective bright edge module 2 to avoid optical interference. In the blue sky light effect module 3, the side-mounted blue LED array 31 is arranged with LEDs of different color temperatures, and works with the light guide component 32 to convert the side-incident light into uniform forward light, replacing the traditional Rayleigh diffuser to achieve thinness. The pseudo-reflective bright edge module 2 emits light from the bright edge light source 21 to the arc-shaped surface of the deformable reflective sheet 23, using the surface reflection to expand the light distribution angle, and then scatters it through the atomizing edge cover 22 to form a continuous light band, eliminating the particle effect of LED beads caused by direct light. Among them, the deformable reflective sheet 23 is squeezed by the slot of the frame 1 to form a specific curvature, so that the point light source is reflected to form a wide-angle diffused light. Combined with the tilt angle and scattering microstructure of the atomizing edge cover 22, the uniformity of the bright edge is doubly guaranteed.

[0033] In some examples, the blue LED array 31 further includes: a first group of LEDs and a second group of LEDs, wherein the first group of LEDs emits blue light of a first wavelength; the second group of LEDs emits blue light of a second wavelength; and the first group of LEDs and the second group of LEDs are arranged at intervals according to a preset ratio.

[0034] In this example, two sets of LED light sources emitting blue light at different wavelengths are used, arranged at intervals and controlled by a preset ratio, such as... Figure 7 As shown, for example, a 1:3 ratio arrangement achieves a realistic simulation of the blue sky effect. The specific wavelength of blue light emitted by the first group of LEDs complements the different wavelengths of blue light emitted by the second group of LEDs, generating a composite spectrum close to that of a natural sky through color temperature superposition. The intermittent arrangement allows different color temperature light sources to be fully mixed in the light guide component 32, eliminating the color spot phenomenon of a single light source. The preset ratio setting, such as 1:3 (but not limited to the current ratio), ensures that the forward light output formed after being deflected by the light guide component 32 has a uniform color temperature distribution based on the refractive characteristics of different wavelengths of light in the light guide plate. The combined light source arrangement scheme provided in this example replaces the optical structure of the traditional Rayleigh scattering plate. While ensuring the blue sky effect, it reduces the cost dependence of high scattering materials and creates conditions for the application of side-incident light guide technology, thereby supporting the lightweight design of the overall structure.

[0035] In some examples, the light guide assembly 32 further includes a light guide plate and a diffuser plate, wherein the light guide plate receives light from the blue LED array 31 at its light-incident end face; the diffuser plate is located on the light-outcrystal side of the light guide plate; and the light guide plate has microstructures inside that cause the light to be redirected by 90°.

[0036] In this example, the side-incident blue LED array 31 undergoes two optical processing steps through a combination of a light guide plate and a diffuser plate. The light guide plate's light-incident side directly receives the side light from the LED array, and its internal microstructure redirects the light from the side to the front, effectively controlling the light propagation path and avoiding the high cost of traditional Rayleigh diffusers. The diffuser plate, located on the light-emitting side of the light guide plate, performs secondary scattering on the redirected light, eliminating localized light spots and ensuring the uniformity of the light-emitting surface. The combined effect of the light guide plate and diffuser plate achieves the uniform luminous efficiency of traditional Rayleigh diffusers while significantly reducing the lamp thickness through the side-incident light guide structure. Furthermore, the use of conventional optical materials instead of expensive diffusers significantly reduces production costs.

[0037] In some examples, the deformable reflective sheet 23 is further described as a PET specular reflective film, whose curved reflective surface converts point light source light into wide-angle diffused light.

[0038] In this example, PET specular reflective film is used as the base material for the deformable reflective sheet 23. Its high reflectivity ensures efficient light reflection, while its physical properties allow for the formation of a natural curved reflective surface through physical compression of the slot in the frame 1. This curved surface reflects the direct light from a point light source at multiple angles using geometric optics principles, overcoming the limitations of traditional planar reflection and transforming the originally concentrated point light into wide-angle diffused light with a broader coverage area. This not only eliminates the localized high brightness caused by traditional specular reflection but also achieves natural diffusion of light in space through the diversity of the curved surface's reflection paths, ultimately achieving a uniform light distribution.

[0039] In some examples, the atomizing cover 22 is further tilted at an angle of 30°-60°, and its inner surface is provided with scattering microstructures. By limiting the tilt angle range of the atomizing cover and the built-in scattering microstructures, the reflected light is further optimized. Setting the tilt angle of the atomizing cover to 30°-60° ensures effective coverage of the light reflected by the deformable reflector 23, while avoiding ineffective light loss due to an excessively large tilt angle or direct light leakage caused by an excessively small tilt angle. The scattering microstructures on the inner surface of the atomizing cover 22 cause secondary scattering of the wide-angle diffused light formed by the reflector, completely eliminating the graininess of the point light source. At the same time, by changing the light propagation path through physical structure, the final emitted light forms a continuous and uniform luminous edge band, successfully simulating the gradual halo effect formed by natural light on a real window frame.

[0040] In some examples, the faceplate 1 further includes a replaceable mounting structure selected from at least one of the following: a spring clip provided on the side wall, a magnetic module provided on the back, and an aluminum snap-fit ​​groove provided on the top.

[0041] In this example, a replaceable mounting structure overcomes the limitations of traditional fixed lighting fixture installation methods. Specifically, spring clips on the side walls achieve rapid positioning and fixation for recessed installation through elastic deformation; magnetic modules on the back utilize magnetic adsorption for non-destructive installation and easy disassembly; and aluminum panel mounting grooves on the top achieve seamless integration with the ceiling system through profile interlocking. These three mounting structures can be used independently or in combination, allowing the same lighting fixture to adapt to different installation scenarios such as recessed, ceiling-mounted, and integrated installations. Maintaining the stability of the main frame structure allows for flexible switching of installation methods through replaceable components, providing a technical foundation for the diversified development of product appearance.

[0042] In some examples, the skylight with a deformable reflective surface structure further includes a buffer pad 4 positioned above the blue sky light effect module 3, and a back cover 5 located at the top of the face frame.
