Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of lighting fixtures, and in particular to a skylight. Background Technology
[0002] In today's lighting industry, where innovation and personalized experiences are constantly being pursued, skylights, as lighting products that can simulate natural sky scenes and create a unique atmosphere, are gradually gaining market attention. Their development stems from people's increasing pursuit of comfort and a sense of nature in their indoor environments, aiming to bring the clear sky of the outdoors into the indoor environment to enhance user comfort.
[0003] Existing skylight technology primarily revolves around light simulation and the representation of sky effects. Among the key technical means to achieve a clear sky effect, using partial light transmission through the lampshade is a common approach. This design typically involves setting up a light-transmitting structure in a specific area of the lampshade, such as through perforations, the use of translucent materials, or special optical films, allowing light to pass through from a localized location. This visually creates an effect similar to clouds obscuring the sky, with some areas bright and others relatively dark.
[0004] However, this technical solution based on partial light transmission through the lampshade suffers from a problem of monotonous light and shadow effects due to structural limitations. Light only shines through a fixed local area of the lampshade, greatly restricting the distribution and variation of light. As a result, the light and shadow pattern presented by the light remains basically unchanged regardless of the viewing angle or under different usage scenarios and times, lacking dynamic changes and a sense of layering of light in space. Utility Model Content

[0006] The purpose of this disclosure is achieved through the following technical solution:
[0007] A skylight includes a housing structure, a light source structure, and a reflector structure. The light source structure is disposed inside the housing structure, and the reflector structure covers the housing structure. The reflector structure includes an annular inclined reflector, an annular housing, a circular light-transmitting element, and a light guide element. The annular housing has a first receiving cavity. The annular inclined reflector and the light guide element are both disposed in the first receiving cavity. The light guide element abuts against the side wall of the annular housing, and the annular inclined reflector abuts against the side of the light guide element opposite to the annular housing.

[0009] The light source structure includes an annular light-emitting component and a disc light-emitting component. The disc light-emitting component is fixed to the housing structure. One end of the annular light-emitting component abuts against the annular housing, and the other end of the annular light-emitting component abuts against the light guide.
[0010] In one embodiment, the reflective structure further includes an annular reflector disposed between the annular housing and the light guide.

[0012] In one embodiment, the annular light-emitting component further includes a limiting member, the annular housing has a limiting boss, one end face of the limiting member abuts against the side of the annular light source fixing plate away from the light-emitting component, and the other end face of the limiting member abuts against the limiting boss.
[0013] In one embodiment, the disc-shaped light-emitting component includes a fixed disk and a plurality of LED beads, the plurality of LED beads being spaced apart along the fixed disk, and the disc-shaped light-emitting component being disposed above the circular light-transmitting element.
[0014] In one embodiment, the fixed plate has a plurality of first mounting through holes, the housing structure includes a base plate and a partition plate, the base plate has a plurality of second mounting through holes, and each of the first mounting through holes is connected to a second mounting through hole.
[0015] In one embodiment, one end of the partition plate is connected to the base plate, the other end of the partition plate abuts against the circular light-transmitting element, and the partition plate is perpendicular to the circular light-transmitting element.
[0016] In one embodiment, the housing structure further includes an annular boss, which forms a second receiving cavity with the base plate, and the skylight further includes a base structure disposed within the second receiving cavity.
[0017] In one embodiment, the housing structure further includes a plurality of mounting buckles, the base structure includes a mounting cover plate and a plurality of snap-fit members, each snap-fit member is fixed to the inner wall of the mounting cover plate, each mounting buckle is fixed in the second receiving cavity, and each snap-fit member is snapped into a mounting buckle.
[0018] In one embodiment, the light guide is a laser-dotted light guide.

[0020] The aforementioned skylight, through its control system, can coordinate the ring-shaped and disc-shaped light-emitting components to output multi-dimensional light combinations, enhancing the dynamic effects and sense of depth of the skylight. Specifically, the light emitted from the ring-shaped component is reflected by a light guide and transmitted to the ring-shaped inclined reflector, where the reflection from its inclined surface forms an outer ring of light. The light from the disc-shaped component is transmitted through a circular light-transmitting component, creating a central area of light and shadow. This allows the light from the two areas to overlap and merge in space, effectively increasing the light emission angle and enabling the skylight to simulate a sky while achieving a wider light emission angle.

[0031] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0032] like Figures 1 to 6 As shown, a skylight 10 according to an embodiment of the present disclosure includes a housing structure 100, a light source structure 200, and a reflector structure 300. The light source structure 200 is disposed inside the housing structure 100, and the reflector structure 300 covers the housing structure 100. The reflector structure 300 includes an annular inclined reflector 310, an annular housing 320, a circular light-transmitting element 330, and a light guide element 340. The annular housing 320 has a first receiving cavity 3201. The annular inclined reflector 310 and the light guide element 340 are both disposed in the first receiving cavity 3201. The light guide element 340 abuts against the side wall of the annular housing 320, and the annular inclined reflector 310 abuts against the side of the light guide element 340 away from the annular housing 320.
[0033] The annular inclined reflector 310 has an annular inclined light-emitting surface. The light-emitting surface of the annular inclined reflector 310 is disposed adjacent to the circular light-transmitting element 330, and the light-incident surface of the annular inclined reflector 310 is adjacent to the light guide element 340. The annular inclined reflector 310 has an annular receiving groove 3101, and the edge of the circular light-transmitting element 330 is engaged in the annular receiving groove 3101.
[0034] The light source structure 200 includes an annular light-emitting component 210 and a disc light-emitting component 220. The disc light-emitting component 220 is fixed to the housing structure 100. One end of the annular light-emitting component 210 abuts against the annular housing 320, and the other end of the annular light-emitting component 210 abuts against the light guide 340.
[0035] In this embodiment, when the annular light-emitting component 210 is powered on, the light it outputs is incident on the light guide 340. Because the refractive index of the material of the light guide 340 is higher than that of the surrounding medium, and its inner wall is designed as a smooth interface, total internal reflection occurs when the light propagates inside the light guide 340. The reflected light can accurately propagate towards the annular inclined reflector 310. After the light reaches the annular inclined reflector 310, because its incident surface is adjacent to the light guide 340, the light smoothly enters the annular inclined reflector 310. The annular inclined reflector 310 has an annular inclined light-emitting surface, which is disposed adjacent to the circular light-transmitting component 330. The light entering the annular inclined reflector 310 is reflected by the annular inclined light-emitting surface, and the reflected light is emitted towards the circular light-transmitting component 330 and the surrounding space, thereby achieving light output at a specific angle and range. Meanwhile, the light output from the disc-shaped light-emitting component 220, fixed to the housing structure 100 and located directly below the circular light-transmitting component 330, can directly enter the circular light-transmitting component 330. After transmission through the circular light-transmitting component 330, the light finally exits from its surface, forming the light output in the central area. Through this design, the light output from the ring-shaped light-emitting component 210, through the light guide 340 and the ring-shaped inclined reflector 310, combines with the light output from the disc-shaped light-emitting component 220 through the circular light-transmitting component 330, enabling the skylight 10 to output light in different directions and ranges to meet the lighting and optical effect requirements of the skylight at different angles.
[0036] Furthermore, existing skylights generally employ a design scheme where reflectors partially emit light and partially block light. This scheme achieves light intensity distribution control through physical blocking, which easily creates a clear light-dark boundary between the blocked and emitting areas. When the ambient light changes dynamically, light spot discontinuity is very likely to occur, resulting in harsh and unnatural light and shadow transitions. Moreover, the fixed emitting area is limited by the geometric angle of the reflector, making it difficult to dynamically adjust the angle of the emitted light, resulting in a lack of depth in the simulated skylight effect, and thus limiting the dynamic light and shadow simulation effect.
[0037] On the other hand, since the light emitted by the ring-shaped light-emitting component 210 can be transmitted through the ring-shaped inclined reflector 310 and the light guide 340, and reflected by the reflector to the side of the circular light-transmitting component 330, compared with the partial light-blocking design of the traditional skylight reflector, the skylight 10 can be used as an everyday lighting fixture when it is not necessary to simulate the sky effect, emitting only soft white light, thereby improving the applicability of the skylight 10.
[0038] The aforementioned skylight 10, through a control system, can coordinate the ring-shaped light-emitting component 210 and the disc-shaped light-emitting component 220 to output a multi-dimensional combination of light, increasing the dynamic effect and sense of layering of the skylight 10. Specifically, the light emitted by the ring-shaped light-emitting component 210 is reflected and transmitted through the light guide 340 to the ring-shaped inclined reflector 310, forming an outer ring of light through the reflection of its inclined light-emitting surface; the light from the disc-shaped light-emitting component 220 is transmitted through the circular light-transmitting component 330 to form the light and shadow in the central area, so that the light from the two areas overlaps and merges in space, thereby effectively increasing the light emission angle, and thus enabling the skylight 10 to achieve a wider angle of light emission while simulating the sky effect.
[0039] like Figure 3 and Figure 4 As shown, in one embodiment, the reflective structure 300 further includes an annular reflector 350, which is disposed between the annular housing 320 and the light guide 340. In this embodiment, when the annular light-emitting component 210 is powered on, the light it outputs first enters the light guide 340. Since the refractive index of the material of the light guide 340 is higher than that of the surrounding medium, total internal reflection occurs when the light propagates inside the light guide 340. However, in actual propagation, a small amount of light is scattered due to the non-uniformity of the material of the light guide 340, thereby reducing the utilization rate of the light. Furthermore, after the scattered light reaches the highly reflective annular reflector 350, part of the light is reflected back to the light guide 340, thereby improving the utilization rate of the light and reducing the scattering of the light.
[0040] like Figure 4 As shown, in one embodiment, the annular light-emitting component 210 includes an annular light source fixing plate 211 and a plurality of light-emitting elements 212. The plurality of light-emitting elements 212 are spaced apart along the annular light source fixing plate 211, and each light-emitting element 212 is disposed above the light guide 340. In this embodiment, the plurality of spaced light-emitting elements 212 can output light from different positions of the annular light source fixing plate 211, so that the light can be more evenly incident into the light guide 340, avoiding the problem of uneven light distribution caused by local light being too strong or too weak.
[0041] like Figure 4As shown, in one embodiment, the annular light-emitting component 210 further includes a limiting member 213. The annular housing 320 has a limiting boss 321. One end face of the limiting member 213 abuts against the side of the annular light source fixing plate 211 away from the light-emitting component 212, and the other end face of the limiting member 213 abuts against the limiting boss 321. In this embodiment, through the abutting cooperation between the limiting member 213 and the limiting boss 321, the axial position of the annular light source fixing plate 211 within the housing structure 100 can be precisely limited, preventing the annular light-emitting component 210 from shifting vertically due to assembly errors or external forces. This ensures that the relative distance between the light-emitting component 212 and the light guide 340 remains constant, effectively avoiding deviations in the light incident angle caused by positional deviations of the light-emitting component. This ensures stable reflection efficiency of light within the light guide 340, thereby avoiding the problem of reduced light uniformity caused by component loosening.
[0042] like Figure 4 and Figure 5 As shown, in one embodiment, the disc-shaped light-emitting component 220 includes a fixed disk 221 and a plurality of LED beads 222. The plurality of LED beads 222 are spaced apart along the fixed disk 221, and the disc-shaped light-emitting component 220 is positioned above the circular light-transmitting element 330. In this embodiment, by positioning the disc-shaped light-emitting component 220 above the circular light-transmitting element 330, the light emitted by the LED beads 222 can directly enter the circular light-transmitting element 330 via the shortest path, reducing light loss during propagation and thus improving the brightness of the central area of the skylight 10. Simultaneously, because the plurality of LED beads 222 are spaced apart along the fixed disk 221, the light can evenly cover the entire surface of the circular light-transmitting element 330, avoiding light spots or dark areas caused by uneven local light distribution, thereby making the light distribution in the central area more uniform and softer.
[0043] like Figure 5 As shown, in one embodiment, the fixed plate 221 has multiple first mounting through holes 2201, and the housing structure 100 includes a base plate 110 and a partition plate 120. The base plate 110 has multiple second mounting through holes 1101, and each first mounting through hole 2201 is connected to a second mounting through hole 1101. In this embodiment, the design of each first mounting through hole 2201 and a second mounting through hole 1101 is beneficial for the installation and fixation of the disc light-emitting component 220. Specifically, by using fasteners that pass through the first mounting through holes 2201 and the second mounting through holes 1101 in sequence, the disc light-emitting component 220 can be firmly fixed on the base plate 110 of the housing structure 100, thereby ensuring that the disc light-emitting component 220 remains stable during the operation of the skylight 10, without shaking or shifting, and thus ensuring stable light output.
[0044] like Figure 4 and Figure 5As shown, in one embodiment, one end of the partition plate 120 is connected to the base plate 110, and the other end of the partition plate 120 abuts against the circular light-transmitting element 330. The partition plate 120 is perpendicular to the circular light-transmitting element 330. In this embodiment, the partition plate 120 divides the interior of the housing structure 100 into different functional areas. It effectively separates the central area where the disc light-emitting component 220 is located from the peripheral area where the annular light-emitting component 210 is located, preventing mutual interference between the two parts of light. The light emitted by the disc light-emitting component 220 is mainly concentrated in the central area, and is transmitted through the circular light-transmitting element 330 to form a bright and concentrated lighting effect; while the light from the annular light-emitting component 210 is diffused in an outer ring shape by the light guide 340 and the annular inclined reflector 310, thereby ensuring that the two parts of light can propagate according to a predetermined path and manner, avoiding problems such as decreased light uniformity and chaotic light and shadow effects caused by light cross-interference, and thus ensuring that the skylight 10 can output more uniform light.
[0045] like Figure 3 and Figure 6 As shown, in one embodiment, the housing structure 100 further includes an annular boss 130, which, together with the base plate 110, forms a second receiving cavity 1102. The skylight 10 also includes a base structure 400, which is disposed within the second receiving cavity 1102. In this embodiment, the second receiving cavity 1102 provides dedicated installation space for the base structure 400, optimizing the overall structural layout of the skylight 10. This allows the base structure 400 to be well integrated with other parts of the housing structure 100, resulting in a more compact and flat overall structure for the skylight 10, reducing unnecessary space occupation, and facilitating the installation of the skylight 10.
[0046] like Figure 5 and Figure 6As shown, in one embodiment, the housing structure 100 further includes multiple mounting clips 140, and the base structure 400 includes a mounting cover plate 410 and multiple snap-fit members 420. Each snap-fit member 420 is fixed to the inner wall of the mounting cover plate 410, and each mounting clip 140 is fixed within the second receiving cavity 1102. Each snap-fit member 420 is engaged with a mounting clip 140. In this embodiment, each snap-fit member 420 is engaged with a mounting clip 140, achieving a quick and stable connection between the base structure 400 and the housing structure 100. During the assembly of the skylight 10, the base structure 400 can be installed simply by engaging the snap-fit members 420 on the mounting cover plate 410 with the corresponding mounting clips 140 in the second receiving cavity 1102, improving assembly efficiency and reducing assembly difficulty and cost. Meanwhile, this snap-fit method ensures the connection accuracy between the base structure 400 and the housing structure 100, avoiding the overall structural instability caused by loose connections or misalignment, thereby ensuring the stability and reliability of the skylight 10 during operation.
[0047] like Figure 4 As shown, in one embodiment, the light guide 340 is a laser-dotted light guide. In this embodiment, when the annular light-emitting component 210 is powered on, as light propagates within the light guide, the dotted structure disrupts total internal reflection, causing some light rays to scatter and refract at preset positions. The escaped light rays are reflected by the light guide 340 in conjunction with the inclined surface of the annular inclined reflector 310, forming a uniformly distributed annular diffuse light field. Simultaneously, the remaining light rays continue to be transmitted to other dotted areas through total internal reflection, compensating for edge light intensity. This design significantly improves the uniformity of light distribution within the light guide, thereby ensuring uniform coverage of the reflected light by the annular inclined reflector 310.
[0048] Compared with the prior art, this disclosure has at least the following advantages:
[0049] The aforementioned skylight 10, through a control system, can coordinate the ring-shaped light-emitting component 210 and the disc-shaped light-emitting component 220 to output a multi-dimensional combination of light, increasing the dynamic effect and sense of layering of the skylight 10. Specifically, the light emitted by the ring-shaped light-emitting component 210 is reflected and transmitted through the light guide 340 to the ring-shaped inclined reflector 310, forming an outer ring of light through the reflection of its inclined light-emitting surface; the light from the disc-shaped light-emitting component 220 is transmitted through the circular light-transmitting component 330 to form the light and shadow in the central area, so that the light from the two areas overlaps and merges in space, thereby effectively increasing the light emission angle, and thus enabling the skylight 10 to achieve a wider angle of light emission while simulating the sky effect.
[0050] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
