[0024] In order to make the personnel in the art better understand the utility model scheme, the technical scheme in the embodiment of the utility model will be clearly and completely described below in combination with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of the utility model protection.

[0025] The technical scheme in the embodiment of the utility model will be clearly and completely described below in combination with the drawings in the embodiment of the utility model.

[0026] Please refer to Figures 1 to 5The utility model discloses a flat lamp 10, flat lamp 10 includes seat body 100, pattern layer 220 and light source subassembly 300, pattern layer 220 sets up in seat body 100, pattern layer 220 has multiple connected face pattern area 201, and the light transmittance of every face pattern area 201 is different, light source subassembly 300 is installed in seat body 100, and the emergent light of light source subassembly 300 is emitted to flat lamp 10 outside after the multiple face pattern area 201, to make the color that every face pattern area 201 shows is different, wherein the color of every face pattern area 201 includes at least one of hue, brightness, color temperature and saturation, such, because pattern layer 220 has multiple face pattern area 201, and the light transmittance of every face pattern area 201 is different, the emergent light of light source subassembly 300 will produce different degrees of scattering and absorption after passing through the face pattern area 201 of different pattern layer 220, when observing from the outside of flat lamp 10, can see the color that every face pattern area 201 shows is different, for example high light transmittance area looks brighter, and low light transmittance area appears dark, makes every face pattern area 201 produce light and shade contrast effect, helps to form the visual level, thereby making the whole flat lamp 10 form stereoscopic light effect.

[0027] Please refer to Figure 4 In some embodiments, the flat lamp 10 includes a grating sheet 200, the grating sheet 200 is arranged on the seat body 100, the grating sheet 200 includes a grating layer 210, a substrate layer 230 and a pattern layer 220 arranged in sequence, the emergent light of the light source assembly 300 sequentially passes through the pattern layer 220, the substrate layer 230 and the grating layer 210 and is emitted to the outside of the flat lamp 10. Wherein, the substrate layer 230 can be transparent glass or transparent film. The grating layer 210 can be formed by pressing the grating structure on the surface of the substrate layer 230 by rolling process to form the required grating texture. The pattern layer 220 can also be formed by pressing the grating structure on the surface of the substrate layer 230 by rolling process to form the required grating texture, thereby forming a plurality of different face pattern areas 201. The grating texture can include a plurality of black stripes and a plurality of gaps, and the plurality of black stripes and the plurality of gaps are arranged alternately. In this way, when the user's position moves, the flat lamp 10 can make the user see that the position of the outer contour line of the face pattern area 201 changes at different angles without moving the flat lamp 10. In addition, when the light passes through the pattern layer 220, different areas on the pattern layer 220 can preliminarily guide and diffuse the light, then the light continues to pass through the transparent substrate layer 230, and finally the light passes through the grating layer 210, which is affected by the grating structure and diffracts, thereby helping the flat lamp 10 to realize three-dimensional light effect.

[0028] Please refer to Figure 2 and Figure 3In some embodiments, the grating sheet 200 is located in the seat body 100, and the grating sheet 200 and the seat body 100 jointly enclose a containing space, and the light source assembly 300 is located in the containing space, and the side of the grating layer 210 away from the pattern layer 220 is exposed outside the seat body 100. In this way, since the side of the grating layer 210 away from the pattern layer 220 is exposed outside the seat body 100, the user can directly view the grating layer 210 even when the lamp is not turned on, so that the flat lamp 10 can also present a three-dimensional effect without emitting light.

[0029] In addition, the grating sheet 200 and the seat body 100 jointly enclose a containing space, and the light source assembly 300 is located in the containing space, that is, the grating sheet 200 and the seat body 100 jointly serve as the shell of the flat lamp 10, which reduces the use of unnecessary materials, helps to save the manufacturing materials of the flat lamp 10, thereby helping to reduce the manufacturing cost of the flat lamp 10, and also helps to reduce the overall weight of the flat lamp.

[0030] In some embodiments, the planar pattern area 201 can be polygonal. For example, the number of planar pattern areas 201 can be two, the outer contours of the two planar pattern areas 201 can each be parallelogram-shaped, and the two planar pattern areas 201 are connected to each other, so that the flat lamp 10 presents a three-dimensional visual effect of the intersection of the two planar pattern areas 201. For another example, each planar pattern area 201 can be rhombus-shaped, the number of planar pattern areas 201 can be three, and the three planar pattern areas 201 can be connected to each other, so that the flat lamp 10 presents a three-dimensional visual effect of a cube. For another example, each planar pattern area 201 can be triangular, the number of planar pattern areas 201 can be three, and the three planar pattern areas 201 can be connected to each other, so that the flat lamp 10 presents a three-dimensional visual effect of a triangular pyramid.

[0031] Please refer to Figure 1 In some embodiments, the number of light source assemblies 300 is multiple, and the multiple light source assemblies 300 can independently work respectively, each light source assembly 300 corresponds to a planar pattern area 201, and the light emitted by each light source assembly 300 passes through the corresponding planar pattern area 201. In this way, the flat lamp 10 can control the opening or closing of each light source assembly 300 as needed, thereby flexibly adjusting the different needs of the light.

[0032] In addition, each light source assembly 300 corresponds to a specific planar pattern area 201, and the flat lamp 10 can display different patterns or light and shadow effects by controlling different light source assemblies 300, thereby providing personalized lighting experience.

[0033] Moreover, the plurality of light source assemblies 300 can work independently, not only can change the color of the three-dimensional pattern, but also can realize dynamic color change, enhance the visual performance of the flat lamp 10, make the static pattern show dynamic effect, and improve the artistic atmosphere of the space.

[0034] In some embodiments, the light source assembly 300 includes a light source 311 and a light guide plate 312, and the light emitted by the light source 311 passes through the light guide plate 312 and then passes through the planar pattern area 201 and is emitted to the outside of the flat lamp 10. The light guide plate 312 can include a light-in surface and a light-out surface, and the light-out surface is arranged opposite to the light grating sheet 200, and the light-in surface is used to allow the light of the light source 311 to be incident, and the incident light is emitted through the light-out surface. In this embodiment, the light-in surface is a peripheral wall of the light guide plate 312, which is arranged substantially along the thickness direction of the light guide plate 312 and is adjacent to the light-out surface. The light guide plate 312 can also include a back surface opposite to the light-out surface, and the back surface is located on the side of the light guide plate 312 away from the light grating sheet 200, and the light-in surface is connected between the back surface and the light-out surface. The back surface is provided with a textured reflective mesh structure, which is used to diffuse the light in the light guide plate 312. Through the textured reflective mesh structure, the mirror reflection condition can be broken. When the light of the light source 311 enters the inside of the light guide plate 312 through the light-in surface, the light can be diffused to various angles when propagating in the light guide plate 312 due to the effect of the textured reflective mesh structure, so that the light is uniformly emitted through the light-out surface, forming a light-emitting surface with relatively uniform brightness, and then emitted to the corresponding planar pattern area 201. In other embodiments, the number of light sources 311 can be multiple, and the light emitted by the multiple light sources 311 can be incident from the light-in surface of the light guide and then emitted from the light-out surface.

[0035] The light guide plates 312 are arranged in a stacked manner with the light grating sheet 200, so that the light grating sheet 200 and the plurality of light guide plates 312 are more compact, so that the structure of the flat lamp 10 is more compact, thereby helping to reduce the volume of the flat lamp 10.

[0036] In some embodiments, the light source assembly 300 further includes a circuit board 313, and the light source 311 is arranged on the circuit board 313, and the circuit board 313, the light guide plate 312 and the light grating sheet 200 are arranged in a stacked manner, so that the structure of the flat lamp 10 is more compact, thereby helping to reduce the volume of the flat lamp 10.

[0037] In some embodiments, the circuit board 313, the light source 311 and the light grating sheet 200 are arranged in sequence along the axial direction of the seat body 100, and the light guide plate 312, the light source 311 and the side wall of the seat body 100 are arranged in sequence along the axial direction of the seat body 100, thereby more helping the flat lamp 10 to be arranged in a plate shape, and thereby making the structure of the flat lamp 10 more compact.

[0038] In some embodiments, the flat lamp 10 further comprises a diffusion film 400, which is installed in the base 100, and the light emitted by the light source assembly 300 passes through the diffusion film 400 and the planar pattern area 201 in sequence. In this way, the light emitted by the light source assembly 300 is more evenly distributed on the surface of the entire pattern layer 220, avoiding obvious light spots or dark areas, thereby improving the quality of the lighting effect.

[0039] In addition, the light rays have been homogenized before passing through the pattern layer 220, which helps to improve the final visual effect, making the color transition between two adjacent planar pattern areas 201 more natural, enhancing the stereoscopic effect and visual hierarchy.

[0040] In some embodiments, the diffusion film 400 is stacked with the pattern layer 220, so that the diffusion film 400 and the pattern layer 220 are more compactly matched, thereby helping to design the flat lamp 10 to be more compact.

[0041] In some embodiments, the number of diffusion films 400 and light source assemblies 300 is multiple, each light source assembly 300 corresponds to a diffusion film 400, and the light emitted by each light source assembly 300 passes through the corresponding diffusion film 400 and the corresponding planar pattern area 201. In this way, each diffusion film 400 corresponds to a planar pattern area 201, so that the light rays can better combine with the planar pattern area 201 on the grating sheet 200 after passing through the diffusion film 400, forming a more delicate and rich visual effect. This helps to enhance the overall aesthetic and stereoscopic effect of the lamp.

[0042] In addition, each light source assembly 300 is relatively independent of its corresponding diffusion film 400, and if a certain light source assembly 300 or diffusion film 400 has a problem, it can be replaced individually without affecting other parts, simplifying the complexity of maintenance and replacement.
