Technical Field

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

[0002] Among existing lighting devices, skylights (also known as clear sky lights or blue sky lights) are lighting devices that can simulate the visual effect of the sky. They can create a skylight-like lighting effect in indoor spaces that cannot be illuminated by sunlight, providing users with a comfortable visual experience. Existing skylights mainly include a light source, a lens, and a panel that can reproduce the effect of a blue sky, thus achieving the blue sky effect presented by the skylight.

[0003] Current skylight products all provide a static blue sky simulation effect, but the fixed mode affects the actual application effect of skylight products in different scenarios. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a skylight system capable of switching between multiple lighting modes, adapting to various lighting scenarios, and effectively improving the application effect of the skylight system in different scenarios.

[0005] To address the aforementioned technical problems, the present invention provides a skylight system, comprising: The lamp housing contains a main light cavity and a blue sky cavity. A main light module is disposed in the main light cavity, and the main light module is used to output basic illumination light; A blue sky module is disposed in the blue sky cavity, and the blue sky module is located above the main light module; The cloud module includes a first light source and a light guide plate disposed in the blue sky cavity. The light guide plate is located on the light-emitting surface of the blue sky module. The first light source surrounds the light guide plate and faces the side light-incident surface of the light guide plate. The light guide plate has a three-dimensional texture, and the first light source forms a light transmission path in the light guide plate. The three-dimensional texture is located on the light transmission path and is used to scatter the light from the first light source to form uniform diffuse reflection light on the light-emitting surface of the light guide plate.

[0006] As an improvement to the above solution, the wall surface of the light guide plate facing the blue sky module is the light-receiving surface of the light guide plate, and the wall surface of the light guide plate away from the blue sky module is the light-emitting surface of the light guide plate. The three-dimensional texture is located between the light-receiving surface of the light guide plate and the light-emitting surface of the light guide plate.

[0007] As an improvement to the above solution, the three-dimensional texture includes multiple micron-sized scattering particles, which form a preset distribution density within the light guide plate. The preset distribution density gradually decreases from the center of the light guide plate to its edge.

[0008] As an improvement to the above solution, the light guide plate forms at least a first region, a second region, and a third region, which are arranged sequentially along a preset direction, extending from the outer edge of the light guide plate towards the central region of the light guide plate. The plurality of scattering particles form a first density in the first region, a second density in the second region, and a third density in the third region, wherein the first density is 50 particles / cm³. 2 -85 pieces / cm 2 The second density is 100 particles / cm³. 2 -125 pieces / cm 2 The third density is 200-225 particles / cm³. 2 .

[0009] As an improvement to the above scheme, the diameter of the plurality of scattering particles gradually decreases from the center of the light guide plate to the edge of the light guide plate.

[0010] As an improvement to the above scheme, the diameter of the scattering particle in the third region is the first diameter, the diameter of the scattering particle in the second region is the second diameter, and the diameter of the scattering particle in the first region is the third diameter. The first diameter is 180μm-250μm, the second diameter is 120μm-180μm, and the third diameter is 80μm-120μm.

[0011] As an improvement to the above scheme, the color temperature of the light source of the main light module, the color temperature of the light source of the blue sky module, and the color temperature of the light source of the white cloud module are 1500K-10000K.

[0012] As an improvement to the above scheme, the power of the main light module is 4W-30W, the power of the blue sky module is 3W-10W, and the power of the white cloud module is 0.2W-2.5W.

[0013] As an improvement to the above solution, the main light module includes a second light source and a curved lens. The second light source is mounted on the inner top wall of the main light cavity via a fixing plate, and the fixing plate surrounds the blue sky module. The bottom wall of the main optical cavity has a first mounting groove, the top wall of the main optical cavity has a second mounting groove, the bottom of the curved lens is fitted into the first mounting groove, and the top of the curved lens is fitted into the second mounting groove.

[0014] As an improvement to the above solution, the blue sky module includes a third light source, a Rayleigh diffuser, and a reflector. The Rayleigh diffuser is disposed in the blue sky cavity, and the third light source faces the side light-incident surface of the Rayleigh diffuser. The white cloud module is located on the light-emitting surface at the bottom of the Rayleigh diffuser, and the reflector is located on the reflective surface at the top of the Rayleigh diffuser.

[0015] As an improvement to the above solution, the light-emitting surface of the light guide plate is provided with a diffuser plate.

[0016] As an improvement to the above solution, it also includes: A controller is disposed in the lamp housing and is electrically connected to the main light module, the blue sky module and the white cloud module. The controller is used to adjust the color temperature and power of the main light module, the color temperature and power of the blue sky module and the color temperature and power of the white cloud module.

[0017] Implementing this invention has the following beneficial effects: In this embodiment of the sky light system, Rayleigh scattering occurs within the blue sky module, creating a blue sky ambient light on the light-emitting surface of the blue sky module. By arranging a light guide plate with a three-dimensional texture on the light-emitting surface of the blue sky module, and placing a first light source on the side-incident surface of the light guide plate, the three-dimensional texture of the light guide plate is illuminated by the first light source. This creates a soft, clearly defined area of ​​scattered light within the light guide plate and on its light-emitting surface, simulating the outline of clouds in the sky. When the blue sky ambient light from the blue sky module illuminates this scattered light area, a blue sky and white cloud effect is displayed on the light-emitting surface of the light guide plate.

[0018] Furthermore, by combining the blue sky module and the white cloud module, the sky light system can be equipped with a white cloud simulation function, increasing the number of lighting modes. The sky light system can use the main light module to provide users with daily lighting functions, or use the blue sky module alone to create a tranquil blue sky effect. Alternatively, the main light module, the blue sky module, and the white cloud module can be used together to provide users with lighting while creating a blue sky and white cloud effect with white clouds, thereby realizing the switching of multiple lighting modes. This allows users to choose the lighting mode of the sky light system according to their needs, adapting to various lighting scenarios and effectively improving the application effect of the sky light system in different scenarios.

Detailed Implementation

[0020] 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.

[0021] This invention provides a skylight system, such as Figures 1 to 9 As shown, the skylight system includes a lamp housing 1, a main light module 2, a blue sky module 3, and a white cloud module 4. The lamp housing 1 contains a main light cavity 11 and a blue sky cavity 12. The main light module 2 is located in the main light cavity 11 and is used to output basic lighting light to provide basic illumination for the user. The blue sky module 3 is located in the blue sky cavity 12 and is positioned above the main light module 2. The white cloud module 4 includes a first light source 41 and a light guide plate 42 located in the blue sky cavity 12. The light guide plate 42 is located on the light-emitting surface of the blue sky module 3, and the first light source 41 surrounds the light guide plate 42, with the first light source 41 facing the side light-incident surface of the light guide plate 42.

[0022] A three-dimensional texture 423 is formed inside the light guide plate 42. The first light source 41 forms a light transmission path inside the light guide plate 42. The three-dimensional texture 423 is located on the light transmission path. The three-dimensional texture 423 is used to scatter the light from the first light source 41 to form uniform diffuse reflection light on the light-emitting surface of the light guide plate 42, thereby simulating the shape of the outline of clouds in the sky.

[0023] In this embodiment of the sky light system, Rayleigh scattering occurs within the blue sky module 3, creating a blue sky ambient light on the light-emitting surface of the blue sky module 3. By arranging a light guide plate 42 with a three-dimensional texture 423 on the light-emitting surface of the blue sky module 3, and placing a first light source 41 on the side-incident surface of the light guide plate 42, the first light source 41 illuminates the three-dimensional texture 423 of the light guide plate 42. This creates a soft, clearly defined diffused light area within the light guide plate 42 and on its light-emitting surface, simulating the outline of clouds in the sky. When the blue sky ambient light from the blue sky module 3 illuminates this diffused light area, a blue sky and white cloud effect is displayed on the light-emitting surface of the light guide plate 42.

[0024] Furthermore, by utilizing the blue sky module 3 and the white cloud module 4 together, the sky light system can be equipped with a white cloud simulation function, increasing the lighting modes of the sky light system. The sky light system can use the main light module 2 to provide users with daily lighting functions, or use the blue sky module 3 alone to create a tranquil blue sky effect. It can also use the main light module 2, the blue sky module 3, and the white cloud module 4 together to provide users with lighting while creating a blue sky and white cloud effect with white clouds, thereby realizing the switching of multiple lighting modes. This allows users to choose the lighting mode of the sky light system according to their needs, adapting to various lighting scenarios and effectively improving the application effect of the sky light system in different scenarios.

[0025] The basic lighting mode of the skylight system can be switched by controlling the working status of the main light module 2, the blue sky module 3, and the white cloud module 4. In this embodiment, the lighting mode when the main light module 2, the blue sky module 3, and the white cloud module 4 are working simultaneously is defined as the "Vibrant Mode" of the skylight system. In this mode, the main light module 2, the blue sky module 3, and the white cloud module 4 are lit simultaneously, providing users with ample lighting and a blue sky effect. The lighting mode when only the main light module 2 is working is defined as the "Balanced Mode". In this mode, the main light module 2 is lit alone, providing users with everyday lighting. The lighting mode when only the blue sky module 3 is working is defined as the "Relaxed Mode". In this mode, the blue sky module 3 is lit alone, creating a tranquil sky atmosphere.

[0026] In this embodiment, to further ensure the simulation effect of the white cloud module 4 on the sky clouds, the wall surface of the light guide plate 42 facing the blue sky module 3 is the light-receiving surface 421 of the light guide plate, and the wall surface of the light guide plate 42 away from the blue sky module 3 is the light-emitting surface 422 of the light guide plate. The three-dimensional texture 423 is located between the light-receiving surface 421 and the light-emitting surface 422 of the light guide plate.

[0027] Understandably, the light from the first light source 41 contacts the three-dimensional texture 423 between the light-receiving surface 421 and the light-emitting surface 422 of the light guide plate, and is scattered within the light guide plate 42. This ensures that both the scattered light from the three-dimensional texture 423 and the ambient light from the blue sky module 3 are emitted from the light guide plate 42, thereby achieving a three-dimensional visual effect of white clouds on the light-emitting surface 422 of the light guide plate. However, if the texture structure is directly formed on the light-receiving surface 421 or the light-emitting surface 422 of the light guide plate, only a planar cloud outline can be projected when illuminated, failing to reflect the three-dimensionality of clouds in a real sky. Furthermore, since the presented cloud outline and the blue sky atmosphere presented by the blue sky module 3 are located on different plate surfaces, it can easily lead to a sense of disjointedness in the sky cloud effect presented by the sky light system, affecting the user's visual experience.

[0028] As a specific example, such as Figure 4 and Figure 5 As shown, the 3D texture 423 includes multiple micron-sized scattering particles 424, which scatter the light from the first light source 41 to simulate the Mie scattering of sunlight by clouds in the real sky, thereby improving the realism of the cloud effect simulated by the 3D texture 423.

[0029] Multiple scattering particles 424 form a preset distribution density within the light guide plate 42. The preset distribution density gradually decreases along the center of the light guide plate 42 to the edge of the light guide plate 42, ensuring that the multiple scattering particles 424 form a three-dimensional texture 423 with the distribution density gradually increasing from the outside to the inside within the light guide plate 42. After being lit by the first light source 41, the brightness of the scattered light area formed by the three-dimensional texture 423 gradually increases from the outside to the inside, thereby forming a cloud pattern with a gradually clearer outline shape from the outside to the inside within the light guide plate 42. This simulates the visual effect of clouds in the real sky being bright in the middle and fluffy at the edges, improving the visual layering of the simulated cloud pattern and further enhancing the simulation realism of the sky light system.

[0030] In this embodiment, as Figure 4 As shown, the light guide plate 42 forms at least a first region 425, a second region 426 and a third region 427. The first region 425, the second region 426 and the third region 427 are arranged sequentially along a preset direction, which extends from the outer edge of the light guide plate 42 to the central region of the light guide plate 42.

[0031] Multiple scattering particles 424 form a first density in a first region 425, multiple scattering particles 424 form a second density in a second region 426, and multiple scattering particles 424 form a third density in a third region 427. The first density is 50 particles / cm³. 2 -85 pieces / cm 2 The second density is 100 particles / cm³. 2 -125 pieces / cm2 The third density is 200-225 particles / cm³. 2 .

[0032] By arranging the third density of the third region 427 at 200-225 particles / cm 2 The second density arrangement of region 426 is 100 units / cm². 2 -125 pieces / cm 2 The first density arrangement in the first region 425 is 50 particles / cm². 2 -85 pieces / cm 2 This allows the light from the first light source 41 to enter the light guide plate 42, forming the brightest area in the third region 427 to simulate the bright, translucent area at the center of a real cloud, forming a brightness transition area in the second region 426 to simulate the scattering area of ​​the brightness transition of a real cloud, and forming the lowest brightness area in the first region 425 to simulate the shadow area at the edge of a real cloud, thus achieving the visual effect of simulating the dynamic changes in cloud brightness.

[0033] More specifically, such as Figure 5 As shown, the diameter of multiple scattering particles 424 gradually decreases from the center of the light guide plate 42 to the edge of the light guide plate 42. This allows the scattering intensity of the scattering particles 424 to gradually increase from the edge of the light guide plate 42 to the center of the light guide plate 42. Thus, the large-diameter, high-density scattering particles 424 in the central region strongly scatter light to present a bright visual effect of the main body of clouds in the real sky at the center of the light guide plate 42, while the small-diameter, low-density scattering particles 424 in the edge region weakly scatter light to present a hazy visual effect of the edge of clouds in the real sky at the edge of the light guide plate 42, further enhancing the visual realism of the clouds simulated by the three-dimensional texture 423.

[0034] In this embodiment, the diameter of the scattering particle 424 in the third region 427 is the first diameter, the diameter of the scattering particle 424 in the second region 426 is the second diameter, and the diameter of the scattering particle 424 in the first region 425 is the third diameter. The first diameter is 180μm-250μm, the second diameter is 120μm-180μm, and the third diameter is 80μm-120μm. This ensures that after the light from the first light source 41 shines into the light guide plate 42, the scattering intensity of the first region 425, the second region 426, and the third region 427 gradually increases, achieving a visual effect where the center of the light guide plate 42 is bright and the edges of the light guide plate 42 are hazy. At the same time, the high density and large diameter scattering particles 424 in the central region of the light guide plate 42 compensate for the attenuation of light during propagation, reduce the brightness difference of the light-emitting surface, and improve the light-emitting efficiency of the light guide plate 42.

[0035] It should be noted that the light guide plate 42 forms a three-dimensional texture 423 through laser engraving. Specifically, a laser engraving machine can be used to complete the laser engraving of multiple scattering particles 424 within the light guide plate 42. The preset distribution density of the scattering particles 424 can be generated and controlled by the software of the laser engraving machine. Specifically, the software of the laser engraving machine can preprocess the image of the cloud to be simulated, generate a grayscale image, and generate a density gradient dot matrix based on the grayscale image mapping. Subsequently, the software of the laser engraving machine converts the dot matrix into execution instructions, and the laser engraving machine completes the laser engraving of the three-dimensional texture 423 within the light guide plate 42 according to the execution instructions, so that the light guide plate 42 can simulate the cloud effect in a real sky under the action of light.

[0036] The specific structure and working principle of the laser engraving machine are existing technologies and will not be elaborated here.

[0037] Furthermore, it should be noted that when laser engraving forms the scattering particles 424, the engraving parameters can be kept constant. In the third region 427, three or four adjacent scattering particles 424 are engraved into a single particle. In the second region 426, two adjacent scattering particles 424 are engraved into a single particle. In the first region 425, each scattering particle 424 is engraved individually. This ensures that high-density, large-diameter scattering particles 424 are formed in the third region 427, medium-density, medium-diameter scattering particles 424 are formed in the second region 426, and low-density, small-diameter scattering particles 424 are formed in the first region 425, thus ensuring the simulation effect of multiple scattering particles 424 on clouds.

[0038] In this embodiment, the color temperature of the light source of the main light module 2, the color temperature of the light source of the blue sky module 3, and the color temperature of the light source of the white cloud module 4 are all 1500K-10000K. By dimming the light sources of the main light module 2, the blue sky module 3, and the white cloud module 4, the working status of the sky light system can be controlled, and the basic lighting mode of the sky light system can be switched.

[0039] Preferably, when the skylight system is in Vitality Mode, the color temperature of the main light module 2 can vary between 1500K and 6500K to simulate the color temperature of sunlight at different times of the day. The color temperature of the blue sky module 3 and the white cloud module 4 can vary between 1800K and 10000K to simulate the ambient light color temperature of the blue sky at different times of the day. Simultaneously, the white cloud module 4 illuminates the 3D texture 423 to simulate white clouds in the sky. By utilizing the varying color temperatures of the main light module 2 and the blue sky module 3, the rhythm of the skylight system is adjusted to simulate the effects of sunlight and sky scenes at different times of the day. When the skylight system is in Balance Mode, only the main light module 2 operates, with a color temperature of 6500K, to ensure that the main light module 2 can provide basic daily lighting for users. When the sky light system is in relaxed mode, only the blue sky module 3 works. The light source color temperature of the blue sky module 3 is 10000K to ensure that the light from the blue sky module 3, after Rayleigh scattering, presents a tranquil blue sky effect at the light-emitting surface of the sky light system.

[0040] More specifically, based on the different color temperatures of the main light module 2 and the different color temperatures of the blue sky module 3, the sky light's activity modes can be divided into morning mode, noon mode, evening mode, and quiet night mode, and the resulting light color effects are as follows: Figure 8 and Figure 9 As shown.

[0041] In the morning mode, the color temperature of the light source of the main light module 2 gradually increases from 1500K to 2500K, and the color temperature of the light source of the blue sky module 3 gradually increases from 1800K to 5700K. The main light module 2 can be adjusted to an orange-yellow sunrise effect, and the blue sky module 3 can be adjusted to a rosy dawn color, thus using the main light module 2 and the blue sky module 3 together to simulate the sunrise effect.

[0042] When the sky light switches from morning mode to noon mode (noon mode is also a lower-spec version of vitality mode), the color temperature of the light source of the main light module 2 gradually increases from 2500K to 6500K, and the color temperature of the light source of the blue sky module 3 gradually increases from 5700K to 10000K. The main light module 2 can be gradually adjusted to a white midday sunlight effect, and the blue sky module 3 can be gradually adjusted to a pure blue sky effect. In this way, the main light module 2 and the blue sky module 3 work together to simulate midday natural light and improve focus.

[0043] When the sky light switches from noon mode to evening mode, the color temperature of the light source of the main light module 2 gradually decreases from 6500K to 3300K, while the color temperature of the light source of the blue sky module 3 gradually decreases from 10000K to 1800K. The main light module 2 can be gradually adjusted to a reddish-orange evening sunlight effect, and the blue sky module 3 can be gradually adjusted to a sunset color, thus using the main light module 2 and the blue sky module 3 together to simulate the sunset atmosphere.

[0044] When the sky light switches from evening mode to quiet night mode, the color temperature of the light source of the main light module 2 gradually decreases from 3300K to 2700K, and remains at a low color temperature of 2700K with a warm yellow hue. At the same time, the blue sky module 3 is turned off, and the white cloud module 4 is lit at low power. This simulates the effect of a night sky by using the main light module 2, the blue sky module 3, and the white cloud module 4, while avoiding blue light from inhibiting melatonin and promoting sleep for the user.

[0045] Furthermore, to further improve the ease of switching the basic lighting mode of the skylight system, the lighting power of the main light module 2, the blue sky module 3, and the white cloud module 4 can be adjusted. Specifically, the power of the main light module 2 is 4W-30W to ensure that the light provided by the main light module 2 can meet the illuminance requirements of various lighting scenarios such as auxiliary lighting, ambient lighting, daily activity lighting, and high-brightness work lighting, thereby adapting to a variety of different lighting scenarios.

[0046] The power of the Blue Sky Module 3 is 3W-10W to ensure that it can simulate the range of sky brightness at different times of the day, thereby presenting the sky effect at different times of the day and realizing the rhythm regulation of the Blue Sky Module 3.

[0047] The power of the cloud module 4 is 0.2W-2.5W. When the power of the cloud module 4 is below 0.2W, the first light source 41 cannot illuminate the 3D texture 423. When the power of the cloud module 4 is above 2.5W, the brightness of the light from the cloud module 4 can easily interfere with the ambient light of the blue sky module 3, thus destroying the ambient effect of the blue sky module 3. Therefore, by using the above power range, the cloud module 4 can ensure that the first light source 41 of the cloud module 4 can illuminate the 3D texture 423 and simulate the cloud-like outline. At the same time, when the cloud module 4 and the blue sky module 3 work simultaneously, the power of the cloud module 4 is always less than that of the blue sky module 3. This ensures that the brightness of the cloud module 4 is always lower than that of the blue sky module 3, so as to avoid the problem of the blue sky effect simulated by the blue sky module 3 becoming washed out after the ambient light of the cloud module 4 mixes with the ambient light of the blue sky module 3, thereby reducing the saturation of the blue sky module 3's ambient light.

[0048] More preferably, when the white cloud module 4 and the blue sky module 3 work together, the power of the white cloud module 4 is P1 and the power of the blue sky module 3 is P2, with P1 / P2≤1 / 3, so as to further ensure that the ambient light brightness of the white cloud module 4 and the ambient light brightness of the blue sky module 3 are sufficiently large, thereby ensuring that the purity of the ambient light of the blue sky module 3 is not affected by the light from the white cloud module 4.

[0049] As a specific embodiment, in the morning mode, the main light module 2 maintains a light source color temperature of 2500K and a power of 4.2W. The blue sky module 3 and the white cloud module 4 maintain a light source color temperature of 5700K and a power of 3.75W and 0.5W respectively.

[0050] In midday mode, the main light module 2 maintains a light source color temperature of 6500K and a power of 20W. The blue sky module 3 and the white cloud module 4 maintain a light source color temperature of 10000K and a power of 7.5W for the blue sky module 3 and a power of 2.5W for the white cloud module 4.

[0051] In the evening mode, the main light module 2 maintains a light source color temperature of 3300K and a power of 10.5W. The blue sky module 3 and the white cloud module 4 maintain a light source color temperature of 1800K and a power of 7.5W for the blue sky module 3 and a power of 1W for the white cloud module 4.

[0052] In the silent night mode, the color temperature of the light source of the main light module 2 is maintained at 2700K, and the power of the main light module 2 is 6.3W. The blue sky module 3 is turned off, and the power of the white cloud module 4 is 0.2W.

[0053] In balanced mode, the main light module 2 maintains a color temperature of 6500K and a power of 30W, while the cloud module 4 has a power of 0.2W.

[0054] In the relaxed mode, the main light module 2 is off, the light source color temperature of the blue sky module 3 is maintained at 6500K, and the power of the blue sky module 3 is 10W. The white cloud module 4 is off.

[0055] Furthermore, by adjusting the color temperature of the light source of the main light module 2, the blue sky module 3, and the white cloud module 4, and in conjunction with adjusting the power of the main light module 2, the power of the blue sky module 3, and the power of the white cloud module 4, the basic lighting mode of the sky light system can be switched. This enables the sky light system to switch between multiple rhythmic lighting scenes to meet the lighting needs of different times and scenes, while also achieving dynamic light adjustment based on the human body's biological clock.

[0056] In this embodiment, the sky light system also includes a controller (not shown in the figure) installed in the lamp housing 1. The controller is electrically connected to the main light module 2, the blue sky module 3, and the white cloud module 4. The controller is used to adjust the color temperature and power of the main light module 2, the blue sky module 3, and the white cloud module 4. By adjusting the color temperature and power of the main light module 2, the blue sky module 3, and the white cloud module 4 according to the controller settings or adjustments, the current of the main light module 2, the blue sky module 3, and the white cloud module 4 is adjusted, thereby realizing the control of the lighting mode of the sky light system and providing users with a variety of sky effects.

[0057] Specifically, such as Figure 7 As shown, the controller may include a power module, a communication module, a control module, and a drive module. The power module is electrically connected to the communication module, control module, and drive module to provide power. The communication module is electrically connected to the control module, the control module is electrically connected to the drive module, and the drive module is electrically connected to the main light module 2, the blue sky module 3, and the white cloud module 4. The communication module can be connected to a remote control signal or to an external terminal (such as a mobile APP). The remote control and mobile terminal can be configured with multiple function buttons, such as light on / off, morning mode, noon mode, evening mode, quiet night mode, balanced mode, and relaxation mode.

[0058] The communication module can receive function control commands from a remote control or mobile terminal, convert and process the corresponding function control commands, and then transmit them to the control module. The control module generates control signals carrying the color temperature and power information of each module based on the converted function control command signals, and then transmits the control signals to the drive module. The drive module amplifies the received control signals and adjusts the current transmitted to the main light module 2, the blue sky module 3, and the white cloud module 4 based on the control signals, thereby controlling the lighting mode of the sky light system and providing users with different sky effects.

[0059] As an optional embodiment, such as Figure 2 and Figure 6 As shown, the main light module 2 includes a second light source 21 and a curved lens 22. The second light source 21 is mounted on the inner top wall of the main light cavity 11 by a fixing plate. The fixing plate surrounds the blue sky module 3. After the light from the second light source 21 shines on the curved lens 22, the curved contour of the curved lens 22 can guide and arrange the light from the second light source 21, thereby achieving a uniform illuminance distribution on the light-emitting surface of the curved lens 22, so that the main light module 2 can output uniform illumination to meet daily lighting needs.

[0060] Specifically, to ensure the installation stability of the curved lens 22 on the lamp housing 1, and to ensure the stability of the light guide distance between the curved lens 22 and the second light source 21, such as... Figure 6As shown, a first mounting groove 121 is formed on the inner bottom wall of the main light cavity 11, and a second mounting groove 122 is formed on the inner top wall of the main light cavity 11. The bottom of the curved lens 22 is embedded in the first mounting groove 121, and the top of the curved lens 22 is embedded in the second mounting groove 122. This forms an inverted snap-fit ​​structure between the edge of the curved lens 22 and the lamp housing 1, which stably fixes the curved lens 22 to the main light cavity 11 of the lamp housing 1, improving the ease of installation and maintenance of the main light module 2. At the same time, the thickness of the main light cavity 11 is equal to the height of the curved lens 22, thereby compressing the overall thickness of the lighting system and enabling the skylight system to adapt to low-cavity ceiling scenarios.

[0061] As an optional embodiment, such as Figure 2 and Figure 3 As shown, the blue sky module 3 includes a third light source 31, a Rayleigh diffuser 32, and a reflector 33. The Rayleigh diffuser 32 is disposed in the blue sky cavity 12, and the third light source 31 faces the side-incident surface of the Rayleigh diffuser 32. The cloud module 4 is located on the bottom light-emitting surface of the Rayleigh diffuser 32, and the reflector 33 is located on the top reflector surface of the Rayleigh diffuser 32. The light from the third light source 31 can enter the Rayleigh diffuser 32 from the side-incident surface of the Rayleigh diffuser 32, and after multi-segment scattering and refraction by micro-nano particles within the Rayleigh diffuser 32, the light from the third light source 31 is divided into multiple scattered light rays. By superimposing the multiple light rays, the light-emitting surface of the Rayleigh diffuser 32 presents a visual effect of superimposed blue sky effect, giving the blue sky ambient light of the blue sky module 3 a certain three-dimensional feel, ensuring that the sky effect simulated by the sky light system is closer to the real clear sky effect, and further improving the realism of the sky light system's simulation of the real sky.

[0062] It should also be noted that, such as Figure 3 As shown, the light-emitting surface of the light guide plate 42 is provided with a diffuser plate 43. The diffuser plate 43, together with the Rayleigh scattering plate 32 and the light guide plate 42 with the three-dimensional texture 423 engraved inside, can increase the proportion of blue light in the blue sky effect simulated by the blue sky module 3, and further improve the sky simulation effect of the blue sky module 3.

[0063] 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.
