Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and more particularly to a skylight. Background Technology

[0002] Among existing lighting fixtures, skylights can simulate the visual effect of the sky, providing a skylight-like lighting effect for indoor spaces that cannot be illuminated by sunlight, thus simulating natural light. Most existing skylights work by obliquely shining a light source onto a diffuser plate; the light is scattered by the plate after passing through, creating an optical diffusion effect to simulate the sky. While existing skylights can simulate the sky effect, the simulated sky is relatively flat and less realistic compared to a clear sky, and they cannot simulate the effect of sunlight. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a sky light that simulates a clear sky effect more closely resembling a real clear sky, effectively improving the sky light's ability to simulate a clear sky.

[0004] To solve the above-mentioned technical problems, the present invention provides a sky light, comprising:

[0005] Cover;

[0006] The frame has multiple sides, and the cover is disposed on the outer wall surface of the multiple sides. The inner wall surface of the multiple sides encloses and forms a light-emitting cavity.

[0007] An illumination module is disposed on one of the sides of the frame, the light path of the illumination module is directed toward the light-emitting cavity, and the illumination module is adapted to emit direct light;

[0008] A blue sky module is disposed at the top of the frame, and the light path of the lighting module is located below the blue sky module. The blue sky module includes a first light source, a scattering light guide plate, and a reflector. The light incident surface of the scattering light guide plate is disposed on the side of the scattering light guide plate. The first light source faces the light incident surface of the scattering light guide plate, the light emitting surface of the scattering light guide plate faces the light-emitting cavity, the reflector of the scattering light guide plate is located on the side of the scattering light guide plate away from the light-emitting cavity, and the reflector is located on the reflector of the scattering light guide plate.

[0009] The reflective surface of the light-scattering plate is provided with a separator, and the reflective plate abuts against the side of the separator away from the light-scattering plate. The separator has a preset thickness.

[0010] The blue sky module also includes:

[0011] A fixed frame is formed, in which the reflector and the light guide plate are stacked sequentially on the bottom wall of the fixed frame. The first light source is disposed on the side wall of the fixed frame, the light-emitting part of the first light source faces the middle of the light guide plate, and a preset distance is formed between the light-emitting part of the first light source and the light-incident surface of the light guide plate.

[0012] The blue sky module has a buffer pad on the side facing away from the light-emitting cavity, and the blue sky module abuts against the top inner wall of the cover through the buffer pad.

[0013] The top of the frame has a placement groove, a light-transmitting plate is embedded in the placement groove, the blue sky module is embedded in the placement groove, and the light-emitting surface of the scattering light guide plate abuts against the light-transmitting plate. The size of the light-transmitting plate is larger than the size of the scattering light guide plate.

[0014] The bottom wall of the placement slot has an outer edge and an inner edge. The outer edge protrudes outward from the top of the frame, and each outer edge is connected to a side wall. A gap is formed between any two adjacent side walls, and part of the gap faces the first light source.

[0015] The inner edge extends inward, and multiple inner edges enclose a space, the size of which is smaller than the size of the light-scattering plate.

[0016] The lighting module includes a second light source, a convex lens, and a reflector. The second light source is connected to one of the sides via a light source fixing plate. The convex lens is covered by a lens bracket, which is connected to the light source fixing plate. The reflector surrounds the convex lens.

[0017] The frame has a connecting hole on one of its sides, a connector is connected to the outer wall of the side, a mounting groove is formed inside the connector, and the opening of the mounting groove is inclined at a preset angle relative to the top of the frame, the preset angle being less than 90°; the light source fixing plate is disposed on the bottom wall of the mounting groove, and the opening of the mounting groove faces the mounting cavity through the connecting hole.

[0018] The connector has heat dissipation fins on the side facing away from the light source fixing plate.

[0019] The connector has connecting end caps on both sides, and the connector is connected to the outer side wall through the connecting end caps.

[0020] The cover has multiple fasteners on its sidewalls, with some of the fasteners and others located on opposite sides of the cover. Each fastener has a bendable first arm and a second arm with unequal heights. One of the first arm and the second arm is connected to a hanging device.

[0021] Implementing this invention has the following beneficial effects:

[0022] In this embodiment of the sky light, the ambient light from the blue sky module is superimposed from multiple light sources when emitted from the diffused light guide plate, creating a visual effect of overlapping blue sky effects. This gives the diffused blue sky light emitted by the blue sky module a certain three-dimensionality, ensuring that the blue sky effect of the blue sky module is deeper and more three-dimensional. At the same time, the lighting module can simulate the effect of sunlight. Under the superposition of the blue sky effect simulated by the blue sky module and the sunlight effect simulated by the lighting module, the sky light's simulated clear sky effect is closer to the real clear sky effect, effectively improving the sky light's clear sky simulation effect.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0039] The sky light provided by this invention can ensure that the blue sky effect of the sky light is deeper and more three-dimensional, and at the same time can simulate the effect of sunlight, so that the clear sky effect simulated by the sky light can be closer to the real clear sky effect, effectively improving the clear sky simulation effect of the sky light.

[0040] In one specific embodiment of the present invention, such as Figures 1 to 4 As shown, the sky light includes a cover 1, a frame 2, an illumination module 3, and a blue sky module 4. The frame 2 has multiple sides 22, and the cover 1 covers the outer walls of these sides 22. The inner walls of the multiple sides 22 enclose a light-emitting cavity 21. The illumination module 3 is located on one of the sides 22 of the frame 2, with its light path facing the light-emitting cavity 21. The illumination module 3 is designed to emit direct light, allowing the sky light to emit a sharp rectangular light spot, simulating sunlight and enhancing its simulation capabilities. The blue sky module 4 is located at the top of the frame 2, with the light path of the illumination module 3 positioned below it. This ensures that the light path of the illumination module 3, when directed towards the light-emitting cavity 21, does not affect the ambient light of the blue sky module 4.

[0041] The Blue Sky Module 4 includes a first light source 41, a scattering light guide plate 42, and a reflector 43. The light incident surface of the scattering light guide plate 42 is located on the side of the scattering light guide plate 42. The first light source 41 faces the light incident surface of the scattering light guide plate 42, the light emitting surface of the scattering light guide plate 42 faces the light emitting cavity 21, the reflector of the scattering light guide plate 42 is located on the side of the scattering light guide plate 42 away from the light emitting cavity 21, and the reflector 43 is located on the reflector of the scattering light guide plate 42.

[0042] In this embodiment of the sky light, when the light from the first light source 41 enters the scattering light guide plate 42 from the light-incident surface on the side of the scattering light guide plate 42, part of the light is scattered by the micro-nano particles inside the scattering light guide plate 42 and shines out from the light-emitting surface of the scattering light guide plate 42, presenting a blue sky effect; another part of the light is refracted by the scattering light guide plate 42 into the reflector plate 43, and after being reflected by the reflector plate 43 in multiple stages, it shines back into the scattering light guide plate 42, and after being scattered by the micro-nano particles inside the scattering light guide plate 42, it shines out from the light-emitting surface of the scattering light guide plate 42.

[0043] Therefore, when the ambient light from the blue sky module 4 shines from the diffused light guide plate 42, it undergoes multiple light superpositions, presenting a visual effect of superimposed blue sky effects. This gives the diffused blue sky ambient light emitted by the blue sky module 4 a certain three-dimensionality, thus ensuring that the blue sky effect of the blue sky module 4 is deeper and more three-dimensional. At the same time, the lighting module 3 can be used to simulate the effect of sunlight. Under the superposition of the blue sky effect simulated by the blue sky module 4 and the sunlight effect simulated by the lighting module 3, the clear sky effect simulated by the sky light can be closer to the real clear sky effect, effectively improving the clear sky simulation effect of the sky light.

[0044] It should be noted that the Sky Module 4 and the Lighting Module 3 are independent of each other and do not affect each other. The Lighting Module 3 can be used alone, allowing the Sky Light to be used as an indoor lighting fixture to meet the user's lighting needs.

[0045] It should also be noted that, compared to the prior art in which the first light source 41 is set on the back of the Rayleigh plate, in this embodiment, the first light source 41 is set on the side of the scattering light guide plate 42. When designing the sky light structure, there is no need to leave space on the back of the scattering light guide plate 42 to accommodate the light source. This significantly reduces the thickness of the sky light on the back of the blue sky module 4, making the sky light easier to install while reducing the cost of the mold.

[0046] Preferably, the light guide plate 42 is a Rayleigh scattering light guide plate with a thickness of 5mm, and the reflector plate 43 has a thickness of 2.5mm. This ensures that the blue sky module 4 can achieve a deep blue sky simulation effect while maintaining a constant thickness, further ensuring a constant thickness for the sky light. The reflector plate 43 has a light transmittance of 50% and a reflectance of 50%.

[0047] Among them, such as Figure 5 and Figure 6 As shown, the reflective surface of the light-scattering guide plate 42 is provided with a separator 44. The reflector plate 43 abuts against the side of the separator 44 away from the light-scattering guide plate 42. The separator 44 has a preset thickness, thereby separating the light-scattering guide plate 42 and the separator 44 by a certain distance to avoid watermarking caused by the adsorption of the plates when the reflector plate 43 and the light-scattering guide plate 42 come into contact, or other adverse phenomena caused by the contact of the plates. Specifically, the preset thickness is 1mm-2mm, preferably 1mm, to ensure that the separator 44 can separate the light-scattering guide plate 42 and the separator plate while avoiding the thickness of the separator 44 affecting the light transmission between the light-scattering guide plate 42 and the reflector plate 43, and to ensure that the separator 44 does not affect the light output effect of the blue sky module 4.

[0048] Preferably, such as Figure 5 As shown, the separator 44 is a middle frame structure formed by four aluminum materials. The separator 44 abuts against the edge of the light scattering guide plate 42 and the reflector plate 43. The light-emitting surface of the light scattering guide plate 42 faces the internal cavity of the middle frame structure to avoid the separator 44 interfering with the light path of the light scattering guide plate 42.

[0049] It should also be noted that the blue sky module 4 may include a diffuser plate (not shown). The diffuser plate is disposed on the light-emitting surface of the diffuser plate 42. By utilizing the cooperation of the diffuser plate and the diffuser plate 42, the blue color ratio in the blue sky atmosphere simulated by the blue sky module 4 is increased, further improving the clear sky simulation effect of the blue sky module. In this case, to ensure that the thickness of the blue sky module 4 is not affected, the reflector plate 43 can be replaced with mirrored aluminum. The mirrored aluminum can be directly integrally formed with the fixing structure of the blue sky module 4 to ensure the thickness of the blue sky module 4.

[0050] Furthermore, such as Figures 5 to 7 As shown, the blue sky module 4 also includes a fixed frame 45, a reflector 43 and a light-guiding plate 42 stacked sequentially on the bottom wall of the fixed frame 45, and a first light source 41 disposed on the side wall 233 of the fixed frame 45. The fixed frame 45 is used to wrap the reflector 43, the light-guiding plate 42 and the first light source 41 into a whole, thereby preventing the components of the blue sky module 4 from moving relative to each other when the sky light moves, thus affecting the light output effect of the blue sky module 4.

[0051] Preferably, the fixing frame 45 is formed by pressing aluminum material and has a square frame structure. The first light source 41 is installed on the side wall of the fixing frame 45 through the connecting plate 411. Multiple first light sources 41 can be provided and multiple first light sources 41 are bonded to the connecting plate 411 at intervals. The number of first light sources 41 can be adjusted according to specific scenarios and needs. The number of first light sources 41 is not specifically limited here.

[0052] like Figure 5 As shown, the light-emitting part of the first light source 41 faces the middle of the scattering light guide plate 42, and a preset distance is formed between the light-emitting part of the first light source 41 and the light-incident surface of the scattering light guide plate 42. Specifically, the preset distance is preferably 1 mm, so as to ensure that the light from the first light source 41 can be evenly distributed inside the scattering light guide plate 42, avoid light efficiency loss, improve the light utilization efficiency of the scattering light guide plate 42, and at the same time prevent the scattering light guide plate 42 from squeezing the first light source 41 when it expands due to the heat generated by the first light source 41, thus ensuring the working safety of the first light source 41.

[0053] It should be noted here that, to further ensure the assembly stability and ease of assembly of the Blue Sky Module 4, such as Figure 7 As shown, a limiting buckle 451 is provided on the side wall 233 of the fixing frame 45. The limiting buckle 451 is adapted to bend towards the light-emitting surface of the light-scattering guide plate 42, so that a fixing cavity 452 is formed between the limiting buckle 451 and the bottom wall surface of the fixing frame 45. The reflector plate 43 and the light-scattering guide plate 42 are stacked sequentially in the fixing cavity 452. Furthermore, when installing the first light source 41, the reflector plate 43 and the light-scattering guide plate 42, the limiting buckle 451 can be bent away from the fixing cavity 452 to improve the assembly convenience of the Blue Sky module 4; and after the first light source 41, the reflector plate 43 and the light-scattering guide plate 42 are installed, the limiting buckle 451 can be bent towards the fixing cavity 452 to improve the assembly stability of the Blue Sky module 4.

[0054] Among them, such as Figure 2 and Figure 5 As shown, a buffer pad 46 is provided on the side of the blue sky module 4 away from the light-emitting cavity 21. The blue sky module 4 abuts against the top inner wall surface of the cover 1 through the buffer pad 46, so as to protect the blue sky module 4 by using the buffer pad 46 to prevent the blue sky module 4 from directly contacting the top inner wall surface of the cover 1, effectively reducing the damage to the blue sky module 4 when the sky light moves.

[0055] Specifically, the buffer pad 46 is an EVA buffer pad, which utilizes the softness and elasticity of the EVA buffer pad to protect the blue sky module 4. At the same time, the blue sky module 4 can adapt to different thicknesses of blue sky modules 4, thereby improving the adaptability of the cover 1 to blue sky modules 4 of different thicknesses.

[0056] Among them, such as Figure 2 and Figure 8As shown, a placement groove 23 is formed at the top of the frame 2. A light-transmitting plate 47 is embedded in the placement groove 23. The blue sky module 4 is embedded in the placement groove 23, and the light-emitting surface of the scattering light guide plate 42 abuts against the light-transmitting plate 47. The size of the light-transmitting plate 47 is larger than the size of the scattering light guide plate 42, so as to cover the scattering light guide plate 42 with the light-transmitting plate 47, thereby protecting the scattering light guide plate 42, preventing scratches on the light-emitting surface of the scattering light guide plate 42 or preventing dust from adhering to the light-emitting surface of the scattering light guide plate 42, and ensuring the light emission effect of the scattering light guide plate 42.

[0057] Furthermore, such as Figure 2 , Figure 5 , Figure 8 and Figure 9 As shown, the bottom wall of the placement slot 23 has an outer edge 231 and an inner edge 232. The outer edge 231 protrudes outward from the top of the frame 2, and each outer edge 231 is connected to a side wall 233. A notch 234 is formed between any two adjacent side walls 233, with some of the notches 234 facing the first light source 41. Therefore, when connecting the power cord to the first light source 41, the power cord of the first light source 41 can be placed in the placement slot 23 and extended from one of the notches 234. This facilitates the connection of the first light source 41 to power while keeping the power cord of the sky light module 4 neatly arranged, thus avoiding short circuits or electric shocks in the sky light and effectively improving the safety of the sky light. At the same time, it reduces the length and number of power cords used, reduces the cross-tangling of power cords, and improves the overall aesthetics of the sky light.

[0058] like Figure 5 , Figure 8 and Figure 9 As shown, the inner edge 232 extends inward, and multiple inner edges 232 enclose a space 235. The size of the space 235 is smaller than that of the light-guiding plate 42. This ensures the stability of the support for the blue sky module 4 while ensuring that the light from the first light source 41 can be fully incident into the light-guiding plate 42, preventing the light from the first light source 41 from leaking out from the space 235 enclosed by the inner edge 232 of the placement slot 23, thereby further improving the light energy utilization rate of the first light source 41.

[0059] In embodiments of the present invention, such as Figure 4 , Figures 10 to 13As shown, the lighting module 3 includes a second light source 31, a convex lens 32, and a reflector 33. The second light source 31 is connected to one side 22 via a light source fixing plate 34. The convex lens 32 is mounted on the second light source 31 via a lens bracket 35, which is connected to the light source fixing plate 34. The reflector 33 surrounds the convex lens 32, connecting the second light source 31, the convex lens 32, and the reflector 33 into a whole. The light from the second light source 31 can be refracted and focused by the convex lens 32, and then further focused by the reflector 33 to ensure that the light from the second light source 31 converges to form a light spot. When the shapes of the convex lens 32 and the reflector 33 are fixed, the shape of the light spot emitted by the lighting module 3 is specific, thereby ensuring that the skylight can simulate the illumination effect of sunlight using the lighting module 3.

[0060] Among them, such as Figures 9 to 13 As shown, one side 22 of the frame 2 is provided with a connecting hole 24, and a connector 36 is connected to the outer wall of the side 22. A mounting groove 361 is formed inside the connector 36, and the opening of the mounting groove 361 is inclined at a preset angle relative to the top of the frame 2, the preset angle being less than 90°. The light source fixing plate 34 is provided on the bottom wall of the mounting groove 361, and the opening of the mounting groove 361 faces the mounting cavity through the connecting hole 24.

[0061] It is understandable that when the second light source 31 is mounted on the bottom wall of the mounting groove 361 via the light source fixing plate 34, the light-emitting part of the second light source 31 faces the same direction as the opening of the mounting groove 361. When the opening of the mounting groove 361 forms a preset angle with the top of the frame 2, the light-emitting part of the second light source 31 also forms a preset angle with the top of the frame 2. Therefore, when the lighting module 3 and the blue sky module 4 are mounted on the frame 2, they are kept relatively tilted at an angle of less than 90°. This ensures that the direct light emitted by the lighting module 3, after hitting the light-emitting cavity 21, always lies below the blue sky module 4 and does not illuminate it, thus ensuring that the light path of the lighting module 3 does not affect the ambient light of the blue sky module 4.

[0062] It should be noted that the orientation of the convex lens 32 and the reflector cup 33 is perpendicular to the light source fixing plate 34, so as to ensure that the orientation of the convex lens 32 and the reflector cup 33 is the same as the opening orientation of the mounting groove 361, further ensuring that the light path of the lighting module 3 forms a preset angle with the top of the frame 2.

[0063] It should also be noted that the preset angle between the opening of the mounting slot 361 and the top of the frame 2 can be set according to the size of the light-emitting cavity 21 to ensure that most of the light from the second light source 31 can be directly emitted from the light-emitting cavity 21, ensuring that the light spot emitted by the lighting module 3 has a sharp boundary and a regular shape. In this embodiment, the preset angle is preferably 35°.

[0064] Specifically, such as Figure 12 As shown, the lighting module 3 includes multiple second light sources 31, multiple convex lenses 32, and multiple reflectors 33. The multiple second light sources 31 are spaced apart on the light source fixing plate 34, and each second light source 31 is equipped with a convex lens 32 and a reflector 33. The lens bracket 35 is integrally formed with the light source fixing plate 34. The lens bracket 35 has a slot 351. Each reflector 33 has a connecting block 331 on its top surface. Adjacent reflectors 33 are connected by the connecting block 331. The side of the connecting block 331 facing the lens bracket 35 has a buckle 332. The reflector 33 is installed on the lens bracket 35 through the buckle 332 and the slot 351, so as to ensure that the various components of the lighting module 3 are connected to form a whole and that the orientation of the lens and reflector 33 is the same as the orientation of the second light source 31.

[0065] It should be noted here that, as Figure 11 and Figure 12 As shown, the lighting module 3 also includes a faceplate 37. The faceplate 37 is detachably connected to the reflector cup 33. The side of the faceplate 37 facing the reflector cup 33 abuts against the plane of the reflector cup 33, and the faceplate 37 forms a reflective slope that surrounds the reflective surface of the reflector cup 33. This utilizes the faceplate 37 to act as the outer ring structure of the reflective surface of the reflector cup 33, ensuring that the reflector cup 33 will not shift when the skylight moves, thereby guaranteeing the illumination angle of the skylight. At the same time, using the faceplate 37 as the outer layer structure of the reflector cup 33 prevents the reflector cup 33 from directly contacting the side of the housing, thus avoiding the wall of the frame 2 from squeezing the reflector cup 33 when the skylight moves, and extending the service life of the reflector cup 33.

[0066] It should also be noted here that, as Figure 13 As shown, the side 22 of the connector 36 has a connection port 364. The tail of the power cord is inserted into the connection port 364 and connected to the second light source 31. The head of the power cord can be connected to the drive through the terminal block to power the second light source 31 and prevent the power cord of the second light source 31 from being pulled and causing dangerous phenomena such as poor contact.

[0067] Furthermore, a significant amount of heat is generated when the second light source 31 emits light. Since the second light source 31 is connected to the connector 36 via the light source fixing plate 34, the heat generated by the second light source 31 can be dissipated to the external environment of the skylight through the connector 36. To improve the heat dissipation efficiency of the connector 36, such as... Figure 11 and Figure 13 As shown, the connector 36 is provided with heat dissipation fins 362 on the side away from the light source fixing plate 34. The heat dissipation fins 362 are used to increase the contact area between the connector 36 and the external environment, accelerate the heat dissipation of the connector 36 to the external environment, and thus accelerate the heat dissipation efficiency of the connector 36 on the heat generated by the second light source 31.

[0068] Furthermore, to facilitate the installation of the connector 36 on the outer wall of the side 22 of the frame 2, such as... Figure 2 As shown, connector 36 has connecting end caps 363 on both sides, and connector 36 is connected to the outer wall of side 22 through connecting end caps 363.

[0069] Specifically, the connection between the connector 36 and the connecting end cap 363 can be achieved in two ways, as exemplified below. In the first method, the connector 36 is connected to the connecting end cap 363 via bolts or studs, allowing for individual replacement of either the connector 36 or the connecting end cap 363, thus preventing the lifespan of the connector 36 from being affected by the connecting end cap 363. In the second method, the connector 36 and the connecting end cap 363 are integrally formed, thereby reducing the number of parts in the skylight and simplifying the assembly process. In this embodiment, the first method is preferred for the connection between the connecting end cap 363 and the connector 36.

[0070] More specifically, a connecting groove is formed on the outer wall of the side 22 of the frame 2, and multiple mounting holes are formed on the cover 1. The connecting end cover 363 is provided with a connecting bolt. After the connecting bolt is inserted into the mounting hole, it is threaded into the connecting groove so as to bolt the connecting piece 36 to the outer wall of the side 22 of the frame 2.

[0071] In embodiments of the present invention, such as Figures 1 to 3 , Figure 14 As shown, a plurality of fasteners 11 are provided on the side wall 233 surface of the cover 1, wherein some fasteners 11 and another part of fasteners 11 are respectively provided on opposite sides of the cover 1. The fasteners 11 form a bendable first arm 111 and a second arm 112. The heights of the first arm 111 and the second arm 112 are not equal. One of the first arm 111 and the second arm 112 is connected to a hanging member 13.

[0072] Understandably, when the skylight needs to be installed on the ceiling by means of hanging, the end of the hanging member 13 away from the fixing member 11 can be directly fixed to the ceiling. Then, the hanging members 13 symmetrically arranged on both sides of the skylight and the first hanging arm 111 or the second hanging arm 112 of the fixing member 11 can be used to realize the hanging of the skylight.

[0073] When the skylight needs to be installed flat on the integrated ceiling, the skylight can be moved to the space between two adjacent keels on the integrated ceiling through the hanging bracket 13. After aligning the skylight with the groove of the keel, the first arm 111 or the second arm 112 of the fixing member 11 is abutted against the plane of the two adjacent keels to realize the flat installation of the skylight on the integrated ceiling.

[0074] Since the heights of the first boom 111 and the second boom 112 are not equal, when the skylight needs to be installed on integrated ceilings of different heights, the first boom 111 or the second boom 112 can be bent adaptively, so that the installation structure of the skylight can be adapted to integrated ceilings of different heights, thereby improving the installation adaptability of the skylight.

[0075] Specifically, to facilitate the bending of the first boom 111 and the second boom 112 relative to the fixing member 11, such as Figure 14 As shown, both the first boom 111 and the second boom 112 are connected to the fixing member 11 via a bending portion 113, and the bending portion 113 is provided with a bending hole 114. Therefore, when the first boom 111 and the second boom 112 bend relative to the fixing member 11, the bending hole 114 of the bending portion 113 can effectively reduce the structural strength of the bending portion 113 and reduce stress concentration at the bending portion 113 during bending, thereby improving the bending performance of the fixing member 11 and preventing excessive deformation or breakage of the first boom 111 and the second boom 112 during bending.

[0076] It should be noted that the hanging component 13 is a hanging rope, at least one end of which is formed with a hook 131. At least one of the first boom 111 and the second boom 112 is formed with a hanging hole 115. The hanging rope is connected to the hanging hole 115 of the boom through the hook 131 so as to connect the hanging rope and the fixing component 11.

[0077] It should also be noted that, to further improve the installation flexibility of skylights, such as... Figures 1 to 3 , Figure 15 As shown, the side of the cover 1 is also provided with a plurality of clamping members 12, wherein some clamping members 12 and another clamping members 12 are respectively provided on opposite sides of the cover 1, the bottom of the frame 2 forms an outward extension 14, and the clamping members 12 form a clamping part 121, the clamping part 121 facing the outward extension 14.

[0078] When a skylight needs to be recessed into the ceiling, after moving the ceiling to the ceiling opening position using the hanging bracket 13, the clamping members 12 on one or both sides of the cover 1 can be moved away from the outer extension 14. One side of the cover 1 is first inserted into the ceiling opening, and then the other side of the cover 1 is inserted into the ceiling opening. After the skylight is placed in the ceiling opening, the symmetrical clamping members 12 on both sides and the outer extension 14 cooperate to clamp the side wall 233 of the opening, clamping and fixing the skylight to the ceiling opening, thus achieving recessed installation of the skylight in the ceiling.

[0079] Preferably, the clamping member 12 is a spring clamp, which includes a positioning part 122, a rotating shaft 123 and a clamping part 121. The positioning part 122 can be detachably connected to the cover 1. The clamping part 121 is rotatably connected to the positioning part 122 through the rotating shaft 123. The rotating shaft 123 is provided with a torsion spring 124. Both the positioning part 122 and the clamping part 121 abut against the torsion spring 124. By utilizing the elasticity of the torsion spring 124, after the skylight is embedded in the ceiling opening, the clamping part 121 rebounds and abuts against the wall surface of the ceiling, so that the clamping part 121 cooperates with the outward extension to clamp the skylight to the ceiling.

[0080] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
