[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0031] The skylight provided by this utility model can effectively increase the lighting effect that the skylight can achieve during use, and meet the user's needs.
[0032] In one specific embodiment of this utility model, such as Figures 1 to 8 As shown, the clear sky light includes a housing 1, a blue sky module 2, and a projection module 3. The blue sky module 2 is installed inside the housing 1, and the inner sidewall of the housing 1 encloses a light-emitting cavity 101, with the light-emitting surface of the blue sky module 2 facing the light-emitting cavity 101. A mounting cavity 301 is formed between the inner and outer wall surfaces of the housing 1, and the projection module 3 is disposed in the mounting cavity 301. A light-emitting slot 104 is formed on the outer wall surface of the housing. A projection element 31 is provided in the projection module 3, and the projection element 31 forms at least one projection hole 311. The light path of the projection module 3 passes through the projection hole 311 and shines out of the housing 1 through the light-emitting slot 104.
[0033] According to the skylight provided in this embodiment, the blue sky module 2 can irradiate a three-dimensional blue sky ambient light into the light-emitting cavity 101 of the housing 1 to achieve the skylight's simulated sky light and shadow effect. At the same time, the projection module 3 arranged between the inner and outer walls of the housing 1 irradiates projected lighting light outward from the housing 1, thereby achieving the skylight's simulated sunlight illuminating the room.
[0034] Since the light path of the projection module 3 passes through the projection hole 311 which forms a preset shape, the projection module 3 can project the preset shape of the projection hole 311 onto the wall or other target plane when projecting, so that the light spot of the projection module 3 can form the boundary of the preset shape, thereby enabling the skylight to form a variety of different shapes of lighting spots, effectively increasing the lighting effect that the skylight can achieve when in use, and restoring a variety of lighting application scenarios, effectively meeting the user's needs.
[0035] Specifically, the light-emitting slot 104 can be set on the outer side wall of the housing, and the light path of the projection module illuminates the external space of the skylight through the outer side wall of the housing; the light-emitting slot 104 can also be set on the outer bottom wall of the housing, and the light path of the projection module illuminates the external space of the skylight through the outer bottom wall of the housing at an angle.
[0036] The preset shape of the projection hole 311 in the projection component 31 can be selected according to actual needs. The projection hole 311 can be a polygonal hole or an irregularly shaped hole, such as a square hole or a rectangular hole, so that the projection module 3 can form a square or rectangular light spot, further improving the realism of the indoor lighting effect simulated by the skylight lamp. The projection hole 311 can also be a circular hole to increase the visual softness of the light spot and reduce the generation of glare at the edge of the light spot. In addition, the projection hole 311 can also be a specific irregularly shaped hole such as a star to meet the actual use needs of users. In this embodiment, the projection hole 311 is preferably a rectangular hole.
[0037] It should also be noted that the projector 31 may also have multiple projection holes 311 of different preset shapes, so that the shapes of multiple projection holes 311 can be simultaneously projected onto different areas of the target plane, thereby increasing the visual effect of the projected light spot.
[0038] It should also be noted that the projection element 31 is preferably a film, so as to ensure that the projection spot boundary of the projection module 3 is clear, while making it easy for users to customize the shape of the projection hole 311 according to actual needs and meet actual use requirements.
[0039] In this embodiment, as Figure 4 and Figure 5 As shown, the projection module 3 includes a light source assembly 32, a collimating lens group 33, a projector 31, and a magnifying lens group 34. The collimating lens group 33 is located between the light source assembly 32 and the projector 31, and the magnifying lens group 34 is located on the side of the projector 31 facing away from the collimating lens group 33. When the projection module 3 is powered on, the light source assembly 32 emits illumination light towards the collimating lens group 33, and the collimating lens group 33 converges the diffused illumination light. Then, the collimating lens group 33 illuminates the projector 31 with the converged illumination light, so that the light passing through the projection hole 311 in the projector 31 can form a projection spot of a preset shape after illuminating the magnifying lens group 34. This ensures the illumination effect formed by the projection module 3 and the simulation effect of sunlight incident by the projection module 3, ensuring the uniformity of the overall light effect.
[0040] The light source assembly 32 includes a projection light source 321 and a condenser lens 322. The projection light source 321 is tilted and disposed in the mounting cavity 301. The condenser lens 322 surrounds the projection light source 321, with its light-emitting surface facing the collimating lens group 33. This allows the condenser lens 322 to provide a certain converging effect for the light emitted by the projection light source 321, thereby improving the light energy utilization rate of the projection light source 321. The tilt angle of the projection light source 321 can be set according to actual needs, ensuring that the light from the projection light source 321 can shine from the outer wall of the housing 1 away from the light-emitting cavity 101 to the outside of the housing 1.
[0041] The collimating lens group 33 includes a first collimating lens 331 and a second collimating lens 332. The first collimating lens 331 is located on the light-emitting surface of the light source assembly 32, and the second collimating lens 332 is located between the first collimating lens 331 and the projector 31. The side of the second collimating lens 332 facing the first collimating lens 331 is convex, and the side of the second collimating lens 332 facing the projector 31 is concave.
[0042] Specifically, when the light from the light source assembly 32 shines on the first collimating lens 331, the first collimating lens 331 can reduce the illumination angle of the light from the light source assembly 32 and illuminate the second collimating lens 332. Subsequently, the second collimating lens 332, through the refraction effect of the convex and concave surfaces, makes the light from the light source assembly 32 approach a parallel state, thereby performing a certain degree of collimation operation on the light from the light source assembly 32 and ensuring that the light from the light source assembly 32 can illuminate the light-transmitting hole of the light-transmitting component as much as possible, thereby enhancing the light energy utilization rate of the projection module 3 for the projection light source 321.
[0043] The magnifying lens assembly 34 includes a first imaging lens 341 and a second imaging lens 342. The first imaging lens 341 is located on the side of the projector 31 opposite to the collimating lens assembly 33, and the second imaging lens 342 is located on the side of the first imaging lens 341 opposite to the projector 31. Both sides of the second imaging lens 342 are concave. By combining the first imaging lens 341 and the second imaging lens 342, the light rays intercepted by the projection aperture 311 of the projector 31 are diffused outwards, forming a relatively uniform illumination spot with a certain brightness, thus magnifying the illumination area of the projection module 3 and improving visual comfort.
[0044] Furthermore, such as Figure 3 and Figure 4 As shown, the projection module 3 also includes a hollow projection cylinder 35. The projection cylinder 35 is inclined downward in the mounting cavity 301. Multiple spaced mounting slots 351 are formed inside the projection cylinder 35. The light source assembly 32, collimating lens group 33, projection element 31 and magnifying lens group 34 are installed in the corresponding mounting slots 351. The light source assembly 32, collimating lens group 33, projection element 31 and magnifying lens group 34 are integrated into the projection cylinder 35 through the multiple mounting slots 351 in the projection cylinder 35. This ensures the installation stability of each component in the projection cylinder 35 and avoids the projection element 31 and other components from shaking when the projection cylinder 35 moves with the housing 1, which would affect the projection spot effect.
[0045] Specifically, such as Figure 4As shown, there are 6 mounting slots 351, and the 6 mounting slots 351 are arranged at a certain distance from the inside to the outside. The projection light source 321 is set at the bottom of the projection cylinder 35 through the light source fixing plate. The condenser lens 322, the first collimating lens 331, the second collimating lens 332, the film, the first imaging lens 341 and the second imaging lens 342 are arranged in the corresponding mounting slots 351 in sequence to complete the configuration and fixation of the projection module 3.
[0046] Furthermore, in another embodiment, to ensure the installation stability of the projection cylinder 35 in the mounting cavity 301, such as... Figure 6 As shown, the mounting cavity 301 is provided with a support frame 36. A clamping member 361 is provided at one end of the support frame 36 facing the projection cylinder 35. The clamping member 361 is used to clamp the outer wall surface of the projection cylinder 35, and a locking adjustment member 362 is provided at the top of the clamping member 361. When the projection cylinder 35 is installed in the mounting cavity 301, the locking adjustment member 362 can be loosened, allowing the clamping member 361 to hold the outer wall surface of the projection cylinder 35. Then, the locking adjustment member 362 is adjusted to lock the clamping member 361, thereby locking and fixing the projection cylinder 35 in the mounting cavity 301 through the support frame 36 and the clamping member 361 on the support frame 36, ensuring the installation stability of the projection cylinder 35.
[0047] Optionally, the locking adjustment component 362 can be an adjusting bolt, and the clamping component 361 can be two arc-shaped clamping plates. The top of each of the two arc-shaped clamping plates has an outer protrusion, and each of the two outer protrusions has a through hole. After the adjusting bolt passes through the two through holes, the two arc-shaped clamping plates are locked by a nut.
[0048] In this embodiment, as Figures 1 to 3 As shown, a light-transmitting cover 11 is detachably connected to the light-emitting slot 104. The light-transmitting cover 11 covers the mounting cavity 301. The projection light path of the projection module 3 is emitted through the light-transmitting cover 11. The light-transmitting cover 11 covers and shields the projection module 3 in the mounting cavity 301, thereby preventing environmental factors such as dust or insects from entering the mounting cavity 301 and blocking the light-emitting lens of the projection module 3, ensuring that the light-emitting effect of the projection module 3 is not affected.
[0049] Preferably, the light-transmitting cover 11 is a transparent cover plate. The transparent cover plate can be installed on the outer wall of the housing 1 by means of detachable connection such as bolt connection or snap connection, so as to further ensure that the transparent cover plate will not affect the light output effect of the projection module 3 and ensure that the illumination spot of the skylight is not affected.
[0050] In embodiments of this utility model, such as Figure 6 and Figure 8As shown, the blue sky module 2 includes a blue sky light source 21, a scattering light guide plate 22, and a reflector 23. The light incident surface of the scattering light guide plate 22 is located on its side, and the blue sky light source 21 faces the light incident surface of the scattering light guide plate 22. The reflective surface and the light emitting surface of the scattering light guide plate 22 are positioned opposite each other, and the reflector 23 is located on the reflective surface of the scattering light guide plate 22. The light emitting surface of the scattering light guide plate 22 faces the light-emitting cavity 101. The scattering light guide plate 22 is a Rayleigh scattering light guide plate 22.
[0051] Understandably, when the light from the blue sky light source 21 enters the scattering light guide plate 22 from the side, part of the light is scattered by the micro-nano particles inside the scattering light guide plate 22 and directly shines on the light-emitting cavity 101 from the light-emitting surface of the scattering light guide plate 22; while another part of the light is refracted by the scattering light guide plate 22 into the reflector plate 23, and after being reflected by the reflector plate 23, it shines back into the scattering light guide plate 22, and after being scattered or reflected again by the micro-nano particles inside the scattering light guide plate 22, it is emitted from the light-emitting surface of the scattering light guide plate 22, or reflected back to the reflector plate 23 for secondary or multiple reflections.
[0052] Furthermore, by utilizing the scattering light guide plate 22 and the reflector plate 23, the light from the blue sky light source 21 can be divided into multiple parts that are emitted at intervals. By superimposing these multiple parts of light, the light-emitting surface of the scattering light guide plate 22 can present a visual experience of superimposed blue sky effects, thereby giving the blue sky atmosphere diffused light emitted by the blue sky module 2 a certain sense of three-dimensionality and ensuring that the blue sky effect of the blue sky module 2 is more profound and three-dimensional.
[0053] In addition, by placing the blue sky light source 21 on the side of the scattering light guide plate 22, there is no need to leave space on the back of the scattering light guide plate 22 to accommodate the blue sky light source 21, which significantly reduces the overall thickness of the sky light, facilitates the installation of the sky light, and reduces the mold cost of the sky light.
[0054] Preferably, the color temperature of the blue sky light source 21 is 6880-8100K, the dominant wavelength is 484nm, and its red-green-blue ratio is 15.1%, 78.2%, and 6.6%.
[0055] It should be noted that, as Figure 8 As shown, the Blue Sky Module 2 also includes a light-transmitting plate 24, which is located on the light-emitting surface of the scattering light guide plate 22. The size of the light-transmitting plate 24 is larger than that of the scattering light guide plate 22, so as to cover the scattering light guide plate 22 and protect it, preventing scratches on the light-emitting surface of the scattering light guide plate 22 and preventing dust from adhering to the light-emitting surface of the scattering light guide plate 22, thereby ensuring the light emission effect of the scattering light guide plate 22. In this embodiment, the light-transmitting plate 24 is preferably a transparent material with high light transmittance, so that while protecting the scattering light guide plate 22, the light-transmitting plate 24 also avoids affecting the light emission effect of the scattering light guide plate 22.
[0056] In embodiments of this utility model, to further improve the realism of the blue sky simulation effect of the clear sky light, such as... Figure 2 , Figure 6 and Figure 7 As shown, the skylight also includes a side atmosphere module 4. The housing 1 has a first inner sidewall 102 and a second inner sidewall 103 arranged in an alternating manner. The first inner sidewall 102 has a mounting hole 12. The side atmosphere module 4 is disposed in the mounting hole 12. The mounting hole 12 is connected to a light-cutting plate 41. The light-cutting plate 41 has a light-cutting hole 411. The ambient light path of the side atmosphere module 4 passes through the light-cutting hole 411 and illuminates the second inner sidewall 103. The side atmosphere module 4 can simulate the light and shadow effect of the sun shining on the sidewall of the window on the second inner sidewall 103.
[0057] Understandably, when the ambient light path of the side ambient light module 4 illuminates the inner sidewalls on both sides of the housing 1, the side ambient light module 4 can magnify the shape of the sidewall of the light-cutting hole 411 to illuminate the second inner sidewall 103, and make the ambient light spot formed by the side ambient light module 4 form a clear cutoff line, thereby forming a soft transition area on both inner sidewalls, and the overall light transition is more natural and uniform. Therefore, when the skylight uses the blue sky module 2 and the side ambient light module 4 to realize the blue sky simulation effect, the blue sky simulation effect that can be achieved can be closer to the real sky effect, effectively ensuring the authenticity of the blue sky simulation effect of the skylight.
[0058] It should be noted that the first inner sidewall 102 of the housing 1 has two symmetrically arranged mounting holes 12, and the light-cutting holes 411 of the light-cutting plate 41 in the two mounting holes 12 are also relatively symmetrical, so as to ensure that the two inner sidewalls of the housing 1 can form a consistent side lighting atmosphere effect.
[0059] Specifically, such as Figure 6 and Figure 7 As shown, the side ambient light module 4 includes an ambient light source 42, a convex lens 43, and a mounting box 44. The mounting box 44 is installed in the mounting cavity 301. A light cut-off plate 41 is disposed in the opening of the mounting box 44 facing the light-emitting cavity 101. The ambient light source 42 is installed on the bottom wall of the mounting box 44, and the convex lens 43 covers the ambient light source 42. The convex lens 43 can focus the light from the ambient light source 42 to reduce light loss. The mounting box 44 forms an integrated ambient light module with the ambient light source 42, the convex lens 43, and the light cut-off plate 41. The mounting position of the mounting box 44 in the mounting cavity 301 can be adjusted to adjust the mounting position of the ambient light source 42 according to the actual lighting conditions, ensuring the lighting effect of the ambient light source 42 on the inner side walls on both sides.
[0060] When the mounting box 44 is fixed inside the mounting cavity 301, the ambient light source 42 and the light-cutting hole 411 are staggered to ensure that the light from the ambient light source 42 can be obliquely shone from the light-cutting hole 411 to the inner sidewalls on both sides, further ensuring the simulated incident effect of the ambient light source 42.
[0061] As can be seen from the embodiments listed above, the Skylight of this invention, utilizing the Blue Sky Module 2, can provide a deeper and more three-dimensional blue sky effect; simultaneously, the side lighting effect provided by the Side Atmosphere Module 4, combined with the blue sky effect, enables the Skylight to provide a blue sky simulation effect that more closely resembles a real sky; and the projection module 3 projects the edge shape of the projection hole 311 onto the target plane, allowing the Skylight to form various different shapes of lighting spots with sharp and regular boundaries, effectively improving the lighting effect of the Skylight. The combined use of the Blue Sky Module 2, the Side Atmosphere Module 4, and the Projection Module 3 enables the Skylight to simulate the light and shadow effect of a clear sky window.
[0062] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
