[0002] Among existing lighting devices, skylights can simulate the visual effect of the sky, providing a skylight-like lighting effect for indoor spaces that are not exposed to sunlight, simulating natural light. Most existing skylights use a light source that shines obliquely onto a diffuser panel. The light then scatters through the panel, creating an optical diffusion effect and mimicking the sky's visual effect. However, the light spot produced by skylights is blurred, which reduces the user experience. Utility Model Content

[0009] The blue sky module further includes a light-transmitting plate, which is located on the light-emitting surface of the scattering light guide plate. The size of the light-transmitting plate is larger than that of the scattering light guide plate.

[0012] Among them, a limiting frame is set on the top of the shell, and the limiting frame is detachably connected to the shell. A supporting surface is formed on the side of the limiting frame facing the top inner wall of the shell, and the distance between the supporting surface and the top inner wall of the shell is equal to the thickness of the blue sky module.

[0013] The lighting module includes a second light source, a convex lens and a reflective cup. The second light source is arranged at the second mounting position through a light source fixing plate. The convex lens cover is arranged on the second light source. The reflective cup is arranged around the convex lens.

[0014] The light source fixing plate is tilted relative to the blue sky module, and the tilt angle of the light source fixing plate and the preset angle are complementary angles.

[0015] The second mounting position is a mounting groove formed on the side wall of the housing, the mounting groove is inclined relative to the top of the housing, and the inclination angle of the mounting groove is the preset angle, and the lighting module is arranged in the mounting groove;

The blue sky module is used to emit scattered light of a blue sky atmosphere to simulate a sunny day effect; at the same time, the lighting module is used to emit direct light to simulate the effect of sunlight, thereby enabling the sky light to simulate both sunlight and sunny day effects at the same time.

[0024] Because the blue sky module is located above the lighting module, and the lighting module and the blue sky module are installed at a relative angle of less than 90 degrees, when the lighting module and the blue sky module emit simulated light, the direct light from the lighting module will not illuminate the blue sky module. This prevents the lighting module from affecting the blue sky atmosphere of the blue sky module, while allowing the sky light to use the lighting module to produce a regular light spot. In addition, the light from the lighting module and the ambient light from the blue sky module are integrated with each other, allowing the sky light to create a more three-dimensional and rich light and shadow effect, effectively improving the user experience when using the sky light.

[0034] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0035] The sky light provided by the present invention can utilize the lighting module 3 to illuminate a light spot with a regular shape, so that the sky light forms a more three-dimensional and rich light and shadow effect, effectively improving the user experience when the sky light is illuminated.

[0036] In a specific embodiment of the present invention, Figures 1 to 9 As shown, the skylight includes a housing 1, a blue sky module 4, and a lighting module 3. The housing 1 is formed with a first mounting position 13 and a second mounting position 14, with the first mounting position 13 positioned above the second mounting position 14. The blue sky module 4 is mounted in the first mounting position 13 and is suitable for illuminating a blue sky atmosphere with diffuse light. The lighting module 3 is mounted in the second mounting position 14, with the mounting direction of the lighting module 3 forming a preset angle with the mounting direction of the blue sky module 4, which is less than 90°. The lighting module 3 is suitable for illuminating direct light.

[0037] The sky light provided in this embodiment is configured by setting a blue sky module 4 at the first mounting position 13 and a lighting module 3 at the second mounting position 14. The blue sky module 4 is used to emit scattered light of the blue sky atmosphere to simulate a sunny day effect; at the same time, the lighting module 3 is used to emit direct light to simulate the sunlight effect, thereby enabling the sky light to simulate both sunlight and sunny day effects at the same time.

[0038] Since the blue sky module 4 is located above the lighting module 3 and the lighting module 3 and the blue sky module 4 are installed at a relative inclination of less than 90 degrees, when the lighting module 3 and the blue sky module 4 emit simulated light, the direct light emitted by the lighting module 3 will not illuminate the blue sky module 4. This prevents the lighting module 3 from affecting the blue sky atmosphere of the blue sky module 4, and enables the sky light to use the lighting module 3 to emit a regular light spot. In addition, the light from the lighting module 3 and the ambient light from the blue sky module 4 are integrated with each other, so that the sky light can form a more three-dimensional and rich light and shadow effect, effectively improving the user experience when the sky light is illuminated.

[0039] In addition, the lighting module 3 can also be used alone to utilize the direct light emitted by the sky light so that the sky light can be used as an indoor lighting fixture, thereby increasing the functionality of the sky light.

[0040] It should be noted here that the sky light can also be equipped with an intelligent control system so that the light brightness, color temperature, color and other parameters of the lighting module 3 and the blue sky module 4 can be adjusted through voice control, remote control or mobile phone APP to meet the usage needs of different users.

[0041] It should also be noted that the preset angle formed between the installation directions of lighting module 3 and blue sky module 4 can be set accordingly based on the size of light outlet 15 at the bottom of housing 1 to ensure that most of the light from lighting module 3 is directly emitted from light outlet 15 at the bottom of housing 1, ensuring that the light spot illuminated by lighting module 3 has sharp edges and a regular shape. Preferably, the preset angle is 35°.

[0042] Among them, such as Figure 2 、 Figure 3 and Figure 5 As shown, the blue sky module 4 includes a first light source 41, a scattering light guide plate 42 and a reflecting plate 43. The reflecting surface of the scattering light guide plate 42 is arranged opposite to the light emitting surface, and the light incident surface of the scattering light guide plate 42 is arranged on the side of the scattering light guide plate 42. The first light source 41 is facing the light incident surface of the scattering light guide plate 42, and the reflecting plate 43 is located on the reflecting surface of the scattering light guide plate 42; the scattering light guide plate 42 is a Rayleigh scattering light guide plate 42.

[0043] It is understandable that when the light from the first light source 41 enters the Rayleigh scattering light guide plate 42, part of the light is scattered by the surface of the micro-nano particles inside the scattering light guide plate 42, causing the light-emitting surface of the scattering light guide plate 42 to present a blue sky effect. At the same time, while the light emitted by the first light source 41 is scattered, part of the light is refracted by the reflective surface of the scattering light guide plate 42 to the reflective plate 43, and undergoes multiple reflections inside the reflective plate 43, and then shines out from the light-emitting surface of the scattering light guide plate 42 again, and is scattered again by the surface of the micro-nano particles inside the scattering light guide plate 42, so that the light from the first light source 41 is superimposed when it shines out from the scattering light guide plate 42, presenting a visual effect of superimposed blue sky effects, so that the blue sky atmosphere scattered light emitted by the blue sky module 4 can have a certain three-dimensional sense, thereby making the blue sky effect of the blue sky module 4 deeper.

[0044] Furthermore, because the first light source 41 faces the side light-entering surface of the diffuser light guide plate 42, light from the first light source 41 can directly enter the diffuser light guide plate 42 from the side. Compared to the prior art method of placing the first light source 41 behind the diffuser light guide plate 42, the sky light of this embodiment does not need to reserve space behind the diffuser light guide plate 42 to accommodate the first light source 41, thereby saving vertical space for the sky light and significantly reducing the thickness of the sky light at the back of the blue sky module 4. This makes the sky light easier to install while reducing mold costs.

[0045] Preferably, the color temperature of the first light source 41 is 3880-8100K, the dominant wavelength is 484nm, and its red ratio is 15.1%, green ratio is 78.2%, and blue ratio is 6.6%. After the light from the first light source 41 is scattered by the scattering light guide plate 42, the light output surface of the scattering light guide plate 42 is tested using an illuminometer. The results show that the red ratio of the light output surface of the scattering light guide plate 42 is 12.6%, the green ratio is 35.9%, and the blue ratio is 51.5%, significantly improving the blue ratio of the scattering light guide plate 42.

[0046] Preferably, the thickness of the scattering light guide plate 42 is 5 mm, the thickness of the reflective plate 43 is 2.5 mm, and the transmittance and reflectivity of the reflective plate 43 are 50% and 50%.

[0047] Furthermore, in order to protect the scattering light guide plate 42, as shown in FIG. Figure 2 and Figure 5 As shown, the blue sky module 4 also includes a light-transmitting plate 47, which is located on the light-emitting surface of the scattering light guide plate 42. The size of the light-transmitting plate 47 is larger than that of the scattering light guide plate 42, so that the light-transmitting plate 47 is used to cover the scattering light guide plate 42, 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-emitting effect of the scattering light guide plate 42.

[0048] The light-transmitting plate 47 is preferably a transparent plate with high light transmittance, so as to ensure that the light-transmitting plate 47 can protect the scattering light guide plate 42 while preventing the light-transmitting plate 47 from affecting the light output effect of the scattering light guide plate 42 .

[0049] In this embodiment, Figures 3 to 5 As shown, the blue sky module 4 also includes a fixed frame 45, a reflective plate 43 and a scattering light guide plate 42 are stacked in sequence on the fixed frame 45, and the first light source 41 is arranged on the side wall of the fixed frame 45, so that the reflective plate 43, the scattering light guide plate 42 and the first light source 41 are wrapped into a whole by the fixed frame 45, thereby preventing the various components of the blue sky module 4 from moving relative to each other when the sky light is moved, thereby affecting the light output effect of the blue sky module 4. The light-emitting portion of the first light source 41 is oriented toward the center of the scattering light guide plate 42 to ensure that the light from the first light source 41 can directly enter the interior of the scattering light guide plate 42, and the light from the first light source 41 is evenly distributed inside the scattering light guide plate 42, thereby ensuring a uniform lighting effect of the blue sky module 4.

[0050] Preferably, the fixing frame 45 is pressed and formed from aluminum and has a rectangular structure. The first light source 41 is mounted to the sidewalls of the fixing frame 45 via a connecting plate 411. Multiple first light sources 41 may be provided, and the multiple first light sources 41 are bonded to the connecting plate 411 at intervals. The number of first light sources 41 can be adjusted based on specific scenarios and needs, and is not specifically limited herein.

[0051] It should be noted here that a light-absorbing velvet cloth is provided between the reflective plate 43 and the bottom surface of the fixing frame 45 to absorb the light leaking from the back of the reflective plate 43 and absorb the stray light from the surrounding environment to prevent the stray light from affecting the lighting effect of the blue sky module 4.

[0052] Specifically, if Figure 3 and Figure 4 As shown, the sidewall of the fixing frame 45 is provided with a limiting buckle 451, which is adapted to bend toward the light-emitting surface of the scattering light guide plate 42, so as to form a fixing cavity 452 between the limiting buckle 451 and the bottom wall of the fixing frame 45. The reflective plate 43 and the scattering light guide plate 42 are sequentially stacked in the fixing cavity 452. Furthermore, when installing the first light source 41, the reflective plate 43, and the scattering light 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. After the first light source 41, the reflective plate 43, and the scattering light guide plate 42 are installed, the limiting buckle 451 can be bent toward the fixing cavity 452 to improve the assembly stability of the blue sky module.

[0053] In this embodiment, Figure 2 、 Figure 5 and Figure 6 As shown, a limiting frame 25 is provided on the top of the shell 1, and the limiting frame 25 is detachably connected to the shell 1. A support surface 251 is formed on the side of the limiting frame 25 facing the top inner wall of the shell 1, and the distance between the support surface 251 and the top inner wall of the shell 1 is equal to the thickness of the blue sky module 4. Furthermore, a first mounting position 13 can be formed between the limiting frame 25 and the inner wall of the shell 1 to limit and fix the blue sky module to the top of the shell 1, thereby ensuring the installation stability of the blue sky module. When it is specifically necessary to install the blue sky module 4, the blue sky module 4 can be placed on the support surface 251 of the limiting frame 25, and then the shell 1 is covered on the blue sky module 4 and the limiting frame 25, and the shell 1 and the limiting frame 25 are detachably connected to fix the blue sky module 4 by utilizing the limiting cooperation between the shell 1 and the limiting frame 25.

[0054] The end surface of the limiting frame 25 facing the side of the housing 1 may be provided with a threaded hole, and the side of the housing 1 may be formed with a connecting hole, and a bolt or stud is sequentially passed through the connecting hole of the housing 1 and the threaded hole of the limiting frame 25, thereby threadedly connecting the housing 1 and the limiting frame 25. Of course, the detachable connection between the limiting frame 25 and the housing 1 is not limited to a threaded connection, and may also be a snap connection or other connection methods.

[0055] It should be noted that the lighting module 3 is located below the limiting frame 25 to ensure that the light of the lighting module 3 does not directly illuminate the blue sky module 4, thereby preventing the blue sky atmosphere of the blue sky module 4 from being affected by the lighting module 3.

[0056] In the embodiment of the present utility model, as Figure 2 、 Figures 7 to 9 As shown, the lighting module 3 includes a second light source 31, a convex lens 32, and a reflector cup 33. The second light source 31 is mounted in the second mounting position 14 via a light source fixing plate 34. The convex lens 32 covers the second light source 31, and the reflector cup 33 surrounds the convex lens 32. This allows light from the second light source 31 to be refracted and focused by the convex lens 32, and then further focused by the reflector cup 33, so that the light from the second light source 31 is aggregated to form a light spot. When the shapes of the reflector cup 33 and the convex lens 32 are fixed, the light spot illuminated by the lighting module 3 has a specific shape, thereby ensuring that the lighting module 3 can illuminate a regularly shaped light spot, allowing the sky light to use the lighting module 3 to simulate the illumination effect of sunlight and enable the sky light to be used as an indoor lighting fixture.

[0057] Among them, such as Figure 2 and Figure 7 As shown, the light source fixing plate 34 is tilted relative to the blue sky module 4, and the tilt angle of the light source fixing plate 34 is complementary to the preset angle. This allows the light emission angle of the second light source 31 to form a preset angle with the blue sky module 4. When the convex lens 32 and the reflector cup 33 are connected to the light source fixing plate 34, the orientation of the convex lens 32 and the reflector cup 33 also forms a preset angle with the blue sky module 4, thereby ensuring that the light path of the second light source 31 does not illuminate the blue sky module 4.

[0058] Specifically, the light source fixing plate 34 is provided with a lens bracket 35, and the convex lens 32 is connected to the light source fixing plate 34 through the lens bracket 35; the reflective cup 33 is formed with a buckle on the side facing the light source fixing plate 34, and the lens bracket 35 is formed with a slot, and the reflective cup 33 and the lens are connected by the buckle and the slot to ensure that the convex lens 32 and the reflective cup 33 are stably installed, while ensuring that the orientation of the convex lens 32 and the reflective cup 33 can be controlled by the installation angle of the light source fixing plate 34, further ensuring the light path direction of the lighting module 3.

[0059] In this embodiment, Figure 8 As shown, in order to ensure that the light source fixing plate 34 and the second light source 31 are tilted at the second mounting position 14, the second mounting position 14 is a mounting groove 361 formed on the side wall of the shell 1, and the mounting groove 361 is tilted relative to the top of the shell 1, and the tilt angle of the mounting groove 361 is a preset angle. The light source fixing plate 34 is set on the bottom wall of the mounting groove 361, so that the second light source 31 is installed at the tilt angle of the mounting groove 361, thereby ensuring that the light-emitting angle of the second light source 31 forms a preset angle with the blue sky module 4.

[0060] The lighting module 3 may be installed in the installation slot 361 in the following manner:

[0061] In the first installation method, the side wall of the housing 1 is provided with an opening, and a connector 36 is removably connected to the outer wall of the housing 1. A mounting groove 361 is formed within the connector 36, facing the opening, and communicating with the opening. When installing the lighting module 3, the lighting module 3 can be first installed at the bottom of the mounting groove 361 of the connector 36. The connector 36 is then connected to the side wall of the housing 1, ensuring that the mounting hole is oriented when the connector 36 is installed. This completes the assembly of the lighting module 3. Assembling the lighting module 3 using the connector 36 attached to the outside of the housing 1 effectively ensures convenient installation of the lighting module 3 and improves the efficiency of installation and maintenance of the lighting module 3.

[0062] In the second installation method, the inner wall of the housing 1 is provided with a connecting boss, and a mounting groove 361 is formed within the connecting boss. When installing the lighting module 3, the lighting module 3 can be assembled into the mounting groove 361 of the connecting boss through a recessed installation method. This provides a stable installation environment for the lighting module 3, reduces its contact with dust and moisture in the external environment, thereby extending the service life of the lighting module 3 and reducing the failure rate.

[0063] Furthermore, if Figure 2 、 Figure 7 and Figure 9 As shown, the lighting module 3 also includes a cover 37. The cover 37 is detachably connected to the reflector 33. The side of the cover 37 facing the reflector 33 abuts the flat surface of the reflector 33. The cover 37 also has a reflective slope that surrounds the reflective surface of the reflector 33. This allows the cover 37 to act as the outer ring structure of the reflective surface of the reflector 33, ensuring that the reflector 33 does not shift when the sky light is moved, thereby maintaining the correct illumination angle. Furthermore, the cover 37 serves as the outer layer of the reflector 33, preventing it from directly contacting the side of the housing 1. This prevents the reflector 33 from being squeezed by the housing 1 wall when the sky light is moved, thereby extending the service life of the reflector 33.

[0064] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
