[0038] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is described in detail below by combining with the drawings and specific embodiments.

[0039] As Figure 1 With Figure 2 The utility model discloses a lamp 100, this lamp 100 preferably is the sky curtain lamp. The lamp 100 includes the surface light emitting component 10 and the line light emitting component 20 of assembling in the bottom of surface light emitting component 10. Wherein, surface light emitting component 10 can provide uniform multicolor surface light source, this multicolor surface light source can realize blue sky, white cloud, rainbow and various scenes, and can realize dynamic effect through control. Line light emitting component 20 is annular and is arranged at the bottom of surface light emitting component 10, can provide the similar sun irradiation that can change color and brightness and the window shadow effect left over the window edge. Compared with the prior art sky curtain lamp, the lamp 100 of the utility model has the penetration and the deep feeling, especially when displaying the scene of blue sky, white cloud, can present similar real sky scene.

[0040] As Figure 3 The surface light emitting component 10 includes the surface light source assembly 11 and the first diffusion layer 12 in the light emitting direction of surface light source assembly 11, and the light emitted by the surface light source assembly 11 passes through the first diffusion layer 12 to form direct type light emitting. Preferably, the side of the first diffusion layer 12 towards the surface light source assembly 11 is a matte surface, and the other side is a mirror surface. In this way, the surface light source assembly 11 can be hidden by the matte surface, avoiding the direct exposure of the outline of the surface light source assembly 11. The light emitted by the surface light source assembly 11 forms uniform light spots on the matte surface, greatly improving the uniformity of the light. On the other hand, the mirror surface can efficiently reflect light, enhancing the direct type light emitting effect of the light. After the light emitted by the surface light source assembly 11 passes through the first diffusion layer 12, it can be more uniformly emitted downward, further optimizing the spatial distribution of the light and significantly improving the overall visual effect.

[0041] In combination with Figure 4 In this embodiment, the surface light source assembly 11 includes a surface light source panel 111 and lamp beads 112 integrated on the surface light source panel 111. The lamp beads 112 are arranged in a module form and include A, B, C, and D colored lamp beads. The four colored lamp beads 112 form a unit, and four units form a group. In the horizontal direction, the colors of the lamp beads 112 of adjacent two units are arranged alternately, and in the vertical direction, the lamp beads 112 of adjacent two units are arranged in an array. This arrangement is based on the optical principle of color mixing and uniform distribution, aiming to achieve uniform mixing of multiple colored light, thereby producing a uniform and stable surface light source.

[0042] Of course, in other embodiments, the lamp beads 112 of adjacent two units can be arranged in an array in the horizontal direction, and the colors of the lamp beads 112 of adjacent two units can be arranged alternately in the vertical direction, as long as the uniformity of the surface light source emitted by the surface light source assembly 11 is good. This is not limited here.

[0043] Of course, each unit can also include other number of lamp beads 112, such as three colors of lamp beads, five colors of lamp beads, six colors of lamp beads, etc. That is, a group is composed of multiple units, one unit has multiple colors of lamp beads 112, each color contains one or more single-color lamp beads 112, and the arrangement order of the multi-color lamp beads in each unit can be the same or different, as long as uniform light emission can be achieved, which is not limited here.

[0044] Optionally, the outer side of each lamp bead 112 is equipped with a lens which can diffuse the light emitted by the lamp bead 112, so that the light emitted by each lamp bead 112 is more uniform. In this way, the cooperation of the multiple colors of lamp beads 112, the lens and the first diffusion layer 12 can provide a uniform multi-color surface light source which can realize various rich scenes such as blue sky, white clouds, rainbow, etc. like the sky. In addition, the surface light source assembly 11 of the utility model can also realize dynamic effects by controlling the on-off, color transformation, etc. of each lamp bead 112. Of course, in other embodiments, the outer side of each lamp bead 112 can also not be equipped with a lens, and the uniformity of each color surface can be realized directly through the array arrangement of each group of lamp beads 112, which can be selected according to actual conditions.

[0045] As shown in Figures 5 to 8 and in combination with Figure 3 It is shown that the surface light emitting assembly 10 also includes a first frame 13, and the surface light source assembly 11 and the first diffusion layer 12 are respectively assembled at opposite ends of the first frame 13. In this embodiment, the first frame 13, the surface light source assembly 11 and the first diffusion layer 12 are all arranged in a rectangular shape, and the first diffusion layer 12 is assembled in the first frame 13 through a pressing strip 14. Specifically, the side of the first frame 13 facing the line light emitting assembly 20 is recessed with an assembly groove 131, the outer peripheral edge of the first diffusion layer 12 is provided with an extension part 121 extending into the assembly groove 131, and the pressing strip 14 is pressed into the assembly groove 131 and tightly combined with the extension part 121, preventing the first diffusion layer 12 from being separated from the assembly groove 131.

[0046] Optionally, as shown in Figure 8As shown, the first diffusion layer 12 includes a body portion 122 that shields the area below the surface light source assembly 11. The extension portion 121 includes a first extension portion 1211 extending from the periphery of the body portion 122 in a direction perpendicular to the body portion 122 toward the surface light source assembly 11, and a second extension portion 1212 extending from the edge of the first extension portion 1211 in a direction perpendicular to the first extension portion 1211. That is, the extension portion 121 is L-shaped and perpendicular to the body portion 122 on the side near the surface light source assembly 11. Both the first extension portion 1211 and the second extension portion 1212 are received within the mounting groove 131 and are in contact with the inner wall surface of the mounting groove 131. A pressure strip 14 is pressed into the mounting groove 131 and simultaneously abuts against the first extension portion 1211 and the second extension portion 1212 to press the first diffusion layer 12 firmly.

[0047] Of course, the extension portion 121 may only include the first extension portion 1211 and not the second extension portion 1212, as long as the first diffusion layer 12 can be pressed by the pressure strip 14, there is no limitation here.

[0048] Optional, such as Figure 3 As shown, the surface light-emitting component 10 also includes a dustproof film 15 fitted inside the first frame 13. This dustproof film 15 is made of transparent material and is located in the light-emitting direction of the surface light source component 11, close to the surface light source component 11. The dustproof film 15 prevents insects, dust, and other contaminants from entering the LED bead 112, ensuring that the light emission uniformity of the LED bead 112 is not affected. Optionally, the structure of the dustproof film 15 is the same as that of the first diffusion layer 12, and it is also fitted into the mounting groove 132 of the first frame 13 via a pressure strip 14; details will not be elaborated here.

[0049] like Figure 9 As shown, the linear light-emitting component 20 is arranged around the outer periphery of the first diffusion layer 12, including a linear light source component 21, a second diffusion layer 22 located in the light emission direction of the linear light source component 21, and a second frame 23. The light emitted by the linear light source component 21 also forms direct-downward light emission after passing through the mirror surfaces of the second diffusion layer 22 and the first diffusion layer 12. Specifically, after passing through the second diffusion layer 22, part of the light emitted by the linear light source component 21 is emitted directly downwards uniformly, while the other part shines upwards onto the first diffusion layer 12, is reflected by the mirror surface of the first diffusion layer 12, and then emitted downwards uniformly. Please refer to [reference needed] for details. Figure 11 .

[0050] The linear light source assembly 21 is arranged around the second frame 23, and is assembled between the second diffusion layer 22 and the second frame 23, so that the window shadow similar to the sun irradiation with variable color and brightness can be provided around the surface light source assembly 11, and the clear cutoff line is left on the window frame. The linear light source assembly 21 comprises a linear light source plate 211 and light beads 212 integrated on the linear light source plate 211. The light beads 212 are multicolor light beads, and are arranged in several groups. In the transverse direction, the colors of the adjacent two groups of light beads 212 are staggered. In the longitudinal direction, the adjacent two groups of light beads 212 are arranged in an array, so as to realize uniform light emission of multiple colors.

[0051] As shown in Figure 10 , specifically, the light beads 212 are arranged in the form of modules, and each group includes light beads of R, G, Y and W colors. Of course, the number and color of each group of light beads 212 can be set to other, such as three colors of light beads, five colors of light beads, six colors of light beads, etc. That is, each group includes light beads 212 of multiple colors, and each color of light beads 212 is arranged together. The arrangement order of the multicolor light beads 212 in each group can be the same or different, as long as uniform light emission can be realized, which is not limited here.

[0052] Of course, in other embodiments, the adjacent two groups of light beads 212 can be arranged in an array in the transverse direction, and the colors of the adjacent two groups of light beads 212 are staggered in the longitudinal direction, as long as the uniformity of the linear light source emitted by the linear light source assembly 21 is good, which is not limited here.

[0053] The second diffusion layer 22 is placed in the light emission direction of the light beads 212, and the ratio of the distance between the second diffusion layer 22 and the light beads 212 of the same color on the linear light source plate 211 to the distance between the second diffusion layer 22 and the second frame 23 is less than 0.8.

[0054] As shown in Figure 11 , the second frame 23 is assembled and fixed with the first frame 13 up and down, and the first diffusion layer 12 is arranged close to the second frame 23, so that part of the light emitted by the linear light source assembly 21 can be quickly irradiated to the first diffusion layer 12, and then reflected by the mirror surface of the first diffusion layer 12 to be emitted in a straight-down manner. In this embodiment, the reflectivity of the mirror surface of the first diffusion layer 12 is greater than 60%, so that the first diffusion layer 12 has a mirror reflection effect, can image the window shadow into the lamp 100, including the cutoff line is mapped in the lamp 100, has a deep and transparent feeling, especially in the scene of displaying blue sky and white clouds, can present a scene similar to the real sky.

[0055] Optionally, the matte surface of the first diffusion layer 12 has a transmittance of less than 60% and a haze of greater than 85%, the purpose of which is to cover the LED beads 112, so that the light forms a uniform light spot on its surface. Thus, the first diffusion layer 12 has a light-uniforming effect. Optionally, the haze of the matte surface of the first diffusion layer 12 is greater than 90%, causing strong scattering of light on the matte surface, uniformly diffusing the light in all directions, thereby forming a uniform light spot on its surface, while avoiding LED leakage.

[0056] Optionally, in this embodiment, the first diffusion layer 12 is a diffusion film, and the second diffusion layer 22 is a diffusion plate. Of course, in other embodiments, the first diffusion layer 12 can also be a diffusion plate, and the second diffusion layer 22 can be a diffusion film; or, both the first diffusion layer 12 and the second diffusion layer 22 can be diffusion films; or, both the first diffusion layer 12 and the second diffusion layer 22 can be diffusion plates, as long as uniform light diffusion can be achieved, there is no limitation here.

[0057] Preferably, in this embodiment, the first diffusion layer 12 is a soft film made of transparent PVC material through UV printing, calendering, composite technology, or casting technology, and its thickness is preferably 0.1mm to 0.5mm. This allows the lamp 100 to be relatively lightweight while still meeting the requirements for a large size.

[0058] like Figure 12 As shown, taking calendering technology as an example: two sets of rollers are used, one set being mirror-finish rollers and the other being matte-finish rollers. Two or more mirror-finish rollers are provided and located on the same side of the first diffusion layer 12; two or more matte-finish rollers are also provided and located on the other side of the first diffusion layer 12. Thus, during the calendering process, the mirror surface of the mirror-finish rollers and the matte surface of the matte-finish rollers can be used to ensure that the two sides of the first diffusion layer 12 after calendering are respectively mirror-finish and matte-finish. Figure 12 In this process, the number of both mirror-finish rollers and matte-finish rollers is preferably three, but this should not be a limitation. Those skilled in the art can make specific settings based on the specific length of the first diffusion layer 12. Optionally, the surface roughness Ra of the mirror-finish rollers is <0.0001 micrometers.

[0059] When using UV printing technology, a transparent PVC film with mirrored surfaces on both sides is used. UV printing is performed on one side, using a milky white diffusing material as the printing ink, resulting in a transmittance of 30% to 70% on that side. This effectively shields the LED beads 112. The other side remains mirrored, achieving the same effect as calendering technology.

[0060] Combination Figure 13 and Figure 14As shown, the first diffusion layer 12 has the following functions: a, light uniformity; b, permeability; c, the window shadow spot of the side edge can be mapped in the lamp 100, thereby realizing the depth; d, light; e, large display size.

[0061] In summary, the lamp 100 of the utility model can meet the daily lighting needs, and has the permeability and the depth, especially in the display of the blue sky, the white cloud and the like, can present the similar real sky scene.

[0062] Compared with the prior art, the lamp 100 of the utility model can not only meet the daily lighting needs, but also has the permeability and the depth, especially in the display of the blue sky, the white cloud and the like, can present the similar real sky scene.

[0063] The above embodiments are only used to illustrate the technical solutions of the utility model and not limit, although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced, without departing from the spirit and scope of the technical solutions of the utility model.
