[0032] 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.

[0033] See Figures 1-4 , Figures 1-4 The first embodiment of the skylight of this utility model is shown, which includes a housing 1, a composite functional plate 2, a blue sky module 3, a solar module 4, and a moving mechanism 5. The composite functional plate 2 is disposed inside the housing 1 to divide the housing 1 into a solar cavity 11 and a blue sky cavity 12 with a light outlet. Each component can be connected to the housing 1 via a slotted connection for easy disassembly. Specifically:

[0034] The composite functional panel 2 includes a diffuser plate 21, a light guide plate 22 and a Rayleigh scattering plate 23, with the diffuser plate 21 facing the solar cavity 11.

[0035] The blue sky module 3 is located on the side of the light guide plate 22 and faces the side of the light guide plate 22. The light emitted from the blue sky module 3 enters the composite functional plate 2 through the side of the light guide plate 22 and then shines outward.

[0036] The solar module 4 is positioned inside the solar cavity 11 and faces the diffuser plate 21 via the moving mechanism 5. The light emitted from the solar module 4 enters the composite functional plate 2 through the diffuser plate 21 and then shines outward. The moving mechanism 5 is used to adjust the real-time position of the solar module 4.

[0037] It should be noted that the blue sky module 3 can emit light with a color temperature of 5000K~8000K, with an optimal color temperature of 7500K. When combined with the composite functional board 2, it can achieve a natural blue sky effect. The sun module 4 can emit light with a color temperature of 1500K~6500K and a luminous flux of 30lm~1600lm. When combined with the composite functional board 2, it can achieve a sunspot effect.

[0038] Accordingly, in practical applications, the diffuser plate 21, light guide plate 22, and Rayleigh scattering plate 23 can be stacked in sequence according to the requirements, or in the order of diffuser plate 21, Rayleigh scattering plate 23, and light guide plate 22. In this embodiment, the diffuser plate 21, light guide plate 22, and Rayleigh scattering plate 23 are stacked from top to bottom, and the blue sky module 3 is located on both sides of the light guide plate 22.

[0039] When the blue sky module 3 is lit, the light emitted from the blue sky module 3 enters the light guide plate 22 through both sides of the light guide plate 22. After being refracted and / or reflected within the light guide plate 22, part of the light is evenly directed toward the Rayleigh scattering plate 23 and then shines outward; another part is directed toward the diffuser plate 21 for refraction and / or reflection before shining onto the light guide plate 22 again, and finally onto the Rayleigh scattering plate 23 and then shines outward, thus presenting a natural blue sky effect.

[0040] When the solar module 4 is lit, the light emitted from the solar module 4 from different directions can pass through the diffuser plate 21, the light guide plate 22, and the Rayleigh scattering plate 23 to mix and then be emitted outward, thus presenting a realistic sunspot effect. At the same time, the skylight of this utility model is also equipped with a moving mechanism 5, which can adjust the position of the solar module 4 in real time to simulate the movement trajectory of the sun and enhance the rhythm effect.

[0041] like Figure 2 As shown, solar module 4 includes an optical housing and a solar light source encapsulated within the optical housing. The optical housing has a curved structure.

[0042] It should be noted that sunlight emitted from a curved surface can be refracted and reflected, thereby changing the direction of the light and forming a halo. Therefore, this invention can achieve a light scattering effect while ensuring that the brightness meets the standard.

[0043] The solar light source is preferably a Lambert light source, and the optical housing is preferably a glass housing or a PC (Polycarbonate) housing, but this is not a limitation and can be selected according to the actual situation.

[0044] like Figure 2 and Figure 4 As shown, the moving mechanism 5 includes a track 51 and a moving component 52 disposed in the solar cavity 11. The track 51 is arranged facing the diffuser plate 21. The moving component 52 is disposed in the track 51 and moves back and forth along the track 51. The solar module 4 is disposed on the moving component 52 and moves synchronously with the moving component 52.

[0045] In this embodiment, track 51 is a straight track, which is set along the diagonal of the top surface of the solar cavity 11.

[0046] In practical applications, the moving part 52 can be connected to the track 51 through a transmission mechanism such as gears or chains, and the position of the solar module 4 can be controlled by a knob, handle or motor. The above-mentioned schemes for the movement of the moving part 52 within the track 51 are all existing technologies and widely used, so they will not be described in detail.

[0047] Therefore, by limiting the movement of the solar module 4 within the track 51, this utility model allows for subsequent feasible applications, including but not limited to users moving the solar module 4 to their preferred position before installation and adjusting the position of the solar module 4 after installation.

[0048] Furthermore, the skylight of this utility model also includes a control module 6, which is connected to the blue sky module 3, the sun module 4 and the moving mechanism 5 respectively. The control module 6 is used to control the working status of the blue sky module 3, the sun module 4 and the moving mechanism 5.

[0049] like Figure 5 As shown, the control module 6 includes a power supply unit 61, a communication unit 62, a main control unit 63, and a drive unit 64, specifically:

[0050] The power supply unit 61 is connected to the communication unit 62, the main control unit 63 and the drive unit 64 respectively, so as to supply power to the communication unit 62, the main control unit 63 and the drive unit 64;

[0051] The communication unit 62 is connected to the main control unit 63 and is used to receive control signals and forward the control signals to the main control unit 63.

[0052] The main control unit 63 is connected to the drive unit 64 and is used to send drive commands to the drive unit 64 according to the control signal;

[0053] The drive unit 64 is connected to the blue sky module 3, the sun module 4 and the moving mechanism 5 respectively, and is used to control the working status of the blue sky module 3, the sun module 4 and the moving mechanism 5 according to the drive command.

[0054] It should be noted that the power supply unit 61 is preferably an AC-DC isolated constant voltage power supply, and the communication unit 62 is preferably an infrared communication unit 62, but this is not a limitation and can be set according to the actual situation; in addition, the drive unit 64 includes a DC-DC communication power supply subunit, a DC-DC main control power supply subunit, a DC-DC blue sky power supply subunit, a DC-DC solar power supply subunit, and a DC-DC mobile power supply subunit.

[0055] During operation, the AC-DC isolated constant voltage power supply outputs a constant voltage to the DC-DC communication power supply subunit, the DC-DC main control power supply subunit, the DC-DC Blue Sky power supply subunit, the DC-DC solar power supply subunit, and the DC-DC mobile power supply subunit. Specifically, the DC-DC communication power supply subunit provides power to the communication unit 62, the DC-DC main control power supply subunit provides power to the main control unit 63, the DC-DC Blue Sky power supply subunit provides power to the Blue Sky drive subunit, the DC-DC solar power supply subunit provides power to the solar drive subunit, and the DC-DC mobile power supply subunit provides power to the mobile drive subunit. The communication unit 62 receives remote... After the controller transmits the control signal, it outputs a control signal to the main control unit 63. The main control unit 63 then outputs a PWM signal to the DC-DC Blue Sky Power Subunit, the DC-DC Solar Power Subunit, and the DC-DC Mobile Power Subunit. This causes the DC-DC Blue Sky Power Subunit to adjust the current of the Blue Sky Module 3 according to the PWM signal and present different sky effects by varying the current magnitude. It also causes the DC-DC Solar Power Subunit to adjust the current of the Solar Module 4 according to the PWM signal and present different light spot effects by varying the current magnitude. Furthermore, it causes the DC-DC Mobile Power Subunit to adjust the current of the Mobile Module according to the PWM signal and present different movement effects by varying the current magnitude.

[0056] Therefore, this invention adopts a hidden side-emitting structure, combined with multiple optical systems, to achieve multi-directional light control, reduce the influence of external factors on the lamp, and achieve an ideal blue sky and sun optical effect, giving people a comfortable feeling of being in a natural blue sky and sun. At the same time, this invention adds a movable sun module 4 while achieving the blue sky effect of the clear sky lamp. The sun module 4 can move on the top of the sun cavity 11, solving the problem of the single sun effect and greatly enhancing the user experience.

[0057] See Figure 6 , Figure 6 This illustrates a second embodiment of the skylight of the present invention, and... Figures 1-4 Unlike the first embodiment shown, in this embodiment, the track 51 is a circular arc track, and the midpoint of the chord of the circular arc track overlaps with the midpoint of the top surface of the solar cavity 11.

[0058] See Figures 7-12 , Figures 7-12 This illustrates a third embodiment of the skylight of this invention, and... Figures 1-5 Unlike the first embodiment shown, the skylight in this embodiment also includes a main light module 7 and a rotating mechanism 8. The main light module 7 is mounted on the side wall of the skylight cavity 12 and faces the skylight cavity 12 via the rotating mechanism 8. The rotating mechanism 8 is used to adjust the illumination angle of the main light module 7.

[0059] It should be noted that the main light module 7 can emit light with a color temperature of 1500K~5500K to achieve the main light effect of a square light spot.

[0060] like Figure 10 As shown, the illumination angle of the main light module 7 is the angle ∠ between the light output axis of the main light module 7 and the horizontal plane of the ceiling. α .

[0061] like Figure 9 and Figure 12 As shown, the main light module 7 includes a strip light source plate 71, a strip optical kit 72, and several main light sources 73. The strip optical kit 72 is provided with several lighting mounting positions, and the main light sources 73 correspond one-to-one with the lighting mounting positions. The strip optical kit 72 is mounted on the rotating mechanism 8 through the strip light source plate 71, and the main light sources 73 are mounted on the corresponding lighting mounting positions.

[0062] When the main light module 7 is lit, the light emitted by the main light module 7 passes through the bar optical kit 72 and is emitted, thereby simulating the effect of sunlight shining into the room through the window and presenting a square light spot on the wall.

[0063] Therefore, this utility model considers the needs of natural scenery, human visual perception, and spatial distribution, and combines the blue sky module 3, the main light module 7, and the sun module 4 into an integrated optical system. Specifically: the blue sky module 3 of this utility model shines a side-emitting light source into the light guide plate 22, and then exits through the Rayleigh scattering plate 23 to achieve the ideal blue sky optical effect; the sun module 4 of this utility model achieves the sun effect of natural time periods through a special curved shell 1, a diffuser plate 21, and a moving mechanism, creating a more comfortable and healthy natural light environment in the indoor space; the main light module 7 of this utility model simulates the square light spot of the sun entering through the window through the optical kit 72 and the rotating mechanism 8, which has more functions and better optical effects than existing skylights on the market.

[0064] Furthermore, the control module 6 can also be connected to the main light module 7 and the rotating mechanism 8 respectively, and the control module 6 is also used to control the working status of the main light module 7 and the rotating mechanism 8.

[0065] Correspondingly, the drive unit 64 is also connected to the main light module 7 and the rotating mechanism 8 respectively, and is used to control the working state of the main light module 7 and the rotating mechanism 8 according to the drive command.

[0066] In other words, the drive unit 64 also includes a DC-DC main solar power supply subunit and a DC-DC rotating power supply subunit. The DC-DC solar power supply subunit can adjust the current of the main solar module 7 according to the PWM signal output by the main control unit 63 and present different light spot effects by different current magnitudes. The DC-DC rotating power supply subunit adjusts the current of the rotating module according to the PWM signal and presents different rotation effects by different current magnitudes, thereby adjusting the illumination angle of the main solar module 7.

[0067] 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 utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
