[0039] To make the objectives, technical solutions, and advantages of the present invention more 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 herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0040] See also Figures 1 to 5 , Figures 1 to 5The first embodiment of the clear sky lamp of the present invention is shown, which includes a housing 1, a composite functional board 2, a blue sky module 3, a solar module 4, a moving mechanism 5, and a control module 6. The composite functional board 2 is disposed inside the housing 1 to separate the housing 1 into a solar cavity 11 and a blue sky cavity 12 with a light outlet. The various components can be connected to the housing 1 via slots for easy disassembly. Specifically:

[0041] The composite functional panel 2 includes a diffuser 21, a light guide plate 22 and a Rayleigh scatterer 23. The diffuser 21 is arranged opposite to the solar cavity 11.

[0042] The blue sky module 3 is arranged on the side of the light guide plate 22 and faces the side of the light guide plate 22. The light emitted by the blue sky module 3 passes through the side of the light guide plate 22 and enters the composite functional board 2 and then irradiates outwards.

[0043] The solar module 4 is placed in the solar cavity 11 through the moving mechanism 5 and faces the diffuser 21. The light emitted by the solar module 4 passes through the diffuser 21 and enters the composite functional panel 2 and then irradiates outwards.

[0044] The control module 6 is connected to the blue sky module 3 , the solar module 4 and the moving mechanism 5 respectively. The control module 6 is used to control the working states of the blue sky module 3 , the solar module 4 and the moving mechanism 5 . The moving mechanism 5 is used to adjust the real-time position of the solar module 4 .

[0045] It should be noted that the blue sky module 3 can emit light with a color temperature of 5000K to 8000K, with an optimal color temperature of 7500K. When combined with the composite functional panel 2, it can achieve a natural blue sky effect; and the solar module 4 can emit light with a color temperature of 1500K to 6500K and a luminous flux of 30lm to 1600lm. When combined with the composite functional panel 2, it can achieve a sun spot effect.

[0046] Accordingly, in actual applications, they can be stacked in the order of "diffuser plate 21 - light guide plate 22 - Rayleigh scattering plate 23" or "diffuser plate 21 - Rayleigh scattering plate 23 - light guide plate 22" according to needs; and in this embodiment, the diffuser plate 21, the light guide plate 22 and the Rayleigh scattering plate 23 are stacked in order from top to bottom, and the blue sky module 3 is arranged on both sides of the light guide plate 22.

[0047] When the blue sky module 3 is lit, the light emitted by the blue sky module 3 enters the light guide plate 22 through both sides of the light guide plate 22. After the light is refracted and / or reflected in the light guide plate 22, a portion of the light is evenly emitted toward the Rayleigh scattering plate 23 and then irradiated outward; the other portion is emitted toward the diffuser 21, where it is refracted and / or reflected, and then emitted toward the light guide plate 22 again, and finally emitted toward the Rayleigh scattering plate 23 and then irradiated outward, thereby presenting a natural blue sky effect.

[0048] When solar module 4 is illuminated, light from different directions is mixed through diffuser 21, light guide plate 22, and Rayleigh scattering plate 23 before being emitted outward, creating a realistic sun spot effect. Furthermore, the clear sky lamp of the present invention is equipped with a movement mechanism 5, which allows the position of solar module 4 to be adjusted in real time, thereby simulating the movement of the sun and enhancing the rhythmic effect.

[0049] like Figure 2 As shown, the solar module 4 includes an optical housing and a solar light source encapsulated in the optical housing, and the optical housing is a curved structure.

[0050] It should be noted that the light emitted by the sunlight source can be refracted and reflected in the curved surface structure, thereby changing the direction of the light and forming a certain halo. Therefore, the present invention can achieve a light scattering effect while ensuring that the brightness meets the standard.

[0051] The sunlight source is preferably a Lambertian light source, and the optical housing is preferably a glass housing or a PC (Polycarbonate) housing, but this is not limiting and can be selected according to actual conditions.

[0052] like Figure 2 and Figure 4 As shown, the moving mechanism 5 includes a track 51 and a moving member 52 provided in the solar cavity 11. The track 51 is arranged opposite to the diffuser 21. The moving member 52 is arranged in the track 51 and moves back and forth along the track 51. The solar module 4 is arranged on the moving member 52 and moves synchronously with the moving member 52.

[0053] In this embodiment, the track 51 is a straight track, and the straight track is arranged along the diagonal line of the top surface of the solar cavity 11 .

[0054] In practical applications, the connection between the moving member 52 and the track 51 can be achieved through a transmission mechanism such as gears or chains, and the position of the solar module 4 can be controlled by a knob, a handle or a motor. The above solutions for the movement of the moving member 52 within the track 51 are all existing technologies and are widely used, so they will not be repeated here.

[0055] Therefore, by limiting the movement of the solar module 4 within the track 51 , the present invention provides for subsequent feasible application scenarios including but not limited to users moving the solar module 4 to a desired position before installation and adjusting the position of the solar module 4 after installation.

[0056] 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:

[0057] The power supply unit 61 is connected to the communication unit 62 , the main control unit 63 and the driving unit 64 respectively to supply power to the communication unit 62 , the main control unit 63 and the driving unit 64 ;

[0058] 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;

[0059] The main control unit 63 is connected to the driving unit 64 and is used to send driving instructions to the driving unit 64 according to the control signal;

[0060] The driving unit 64 is connected to the blue sky module 3, the solar module 4 and the moving mechanism 5 respectively, and is used to control the working states of the blue sky module 3, the solar module 4 and the moving mechanism 5 according to the driving instructions.

[0061] 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 actual conditions; in addition, the drive unit 64 includes a DC-DC communication power sub-unit, a DC-DC main control power sub-unit, a DC-DC blue sky power sub-unit, a DC-DC solar power sub-unit and a DC-DC mobile power sub-unit.

[0062] When working, the AC-DC isolated constant voltage power supply outputs a constant voltage to the DC-DC communication power subunit, the DC-DC main control power subunit, the DC-DC blue sky power subunit, the DC-DC solar power subunit and the DC-DC mobile power subunit; wherein, the DC-DC communication power subunit provides a power supply voltage to the communication unit 62, the DC-DC main control power subunit provides a power supply voltage to the main control unit 63, the DC-DC blue sky power subunit provides a power supply voltage to the blue sky drive subunit, the DC-DC solar power subunit provides a power supply voltage to the solar drive subunit, and the DC-DC mobile power subunit provides a power supply voltage to the mobile drive subunit; the communication unit 62 receives a signal from the remote control. After receiving the control signal, the control signal is output to the main control unit 63, and the main control unit 63 outputs the PWM signal to the DC-DC blue sky power sub-unit, the DC-DC solar power sub-unit and the DC-DC mobile power sub-unit after internal processing, so that the DC-DC blue sky power sub-unit adjusts the current of the blue sky module 3 according to the PWM signal and presents different sky effects through different current sizes, the DC-DC solar power sub-unit adjusts the current of the solar module 4 according to the PWM signal and presents different light spot effects through different current sizes, and the DC-DC mobile power sub-unit adjusts the current of the mobile module according to the PWM signal and presents different mobile effects through different current sizes.

[0063] Therefore, the present invention utilizes a hidden side-emitting structure, combined with multiple optical systems, to achieve precise multi-directional light control, reducing the influence of external factors on the lamp, achieving the ideal blue sky sunlight optical effect, and giving people the comfortable feeling of being in the natural blue sky sunlight. Furthermore, while achieving the blue sky effect of the clear sky lamp, the present invention also adds a movable solar module 4. The solar module 4 can be moved on top of the solar cavity 11 and can be electrically dimmed, thus solving the problem of the single-sided solar effect and greatly enhancing the user experience.

[0064] See also Figure 6 , Figure 6 The second embodiment of the clear sky lamp of the present invention is shown. Figures 1 to 5 The difference from the first embodiment shown is that the track 51 in this embodiment is a circular track, and the midpoint of the chord of the circular track overlaps with the midpoint of the top surface of the solar cavity 11 .

[0065] See also Figures 7 to 12 , Figures 7 to 12 The third embodiment of the clear sky lamp of the present invention is shown. Figures 1 to 5 The difference from the first embodiment shown is that the clear sky lamp in this embodiment further includes a main light module 7 and a rotating mechanism 8. The main light module 7 is arranged on the side wall of the blue sky cavity 12 through the rotating mechanism 8 and faces the blue sky cavity 12;

[0066] The control module 6 is connected to the main light module 7 and the rotating mechanism 8 respectively. The control module 6 is used to control the working states of the main light module 7 and the rotating mechanism 8 , and the rotating mechanism 8 is used to adjust the illumination angle of the main light module 7 .

[0067] It should be noted that the main light module 7 can emit light with a color temperature of 1500K to 5500K, so as to achieve a main light effect of a square light spot.

[0068] like Figure 10 As shown, the illumination angle of the main light module 7 is the angle ∠α between the light emitting center axis of the main light module 7 and the horizontal plane of the ceiling.

[0069] 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 a plurality of main light sources 73. The strip optical kit 72 is provided with a plurality of lighting installation positions, and the main light sources 73 correspond to the lighting installation positions one by one; the strip optical kit 72 is provided on the rotating mechanism 8 through the strip light source plate 71, and the main light sources 73 are provided on the corresponding lighting installation positions.

[0070] When the main light module 7 is turned on, the light emitted by the main light module 7 is emitted through the strip optical assembly 72, thereby simulating the effect of sunlight shining into the room through the window and presenting a square light spot on the wall.

[0071] Furthermore, the driving unit 64 is also connected to the main light module 7 and the rotating mechanism 8 respectively, and is used to control the working states of the main light module 7 and the rotating mechanism 8 according to the driving instructions.

[0072] That is to say, the driving unit 64 also includes a DC-DC main light power supply sub-unit and a DC-DC rotating power supply sub-unit, wherein the DC-DC solar power supply sub-unit can adjust the current of the main light module 7 according to the PWM signal output by the main control unit 63 and present different light spot effects through different current sizes, and the DC-DC rotating power supply sub-unit adjusts the current of the rotating module according to the PWM signal and presents different rotation effects through different current sizes, thereby adjusting the illumination angle of the main light module 7.

[0073] Therefore, the present invention takes into account multi-dimensional needs such as natural scenes, human eye perception, and spatial distribution, and combines the blue sky module 3, the main light module 7, and the solar module 4 into an integrated optical system. Specifically: the blue sky module 3 of the present invention uses a side-emitting light source to enter the light guide plate 22, and then emits light through the Rayleigh scattering plate 23 to achieve an ideal blue sky optical effect; the solar module 4 of the present invention uses a special curved shell 1, a diffuser 21, and combines it with an electronically controlled dimming method to achieve a solar effect during natural time periods, creating a more comfortable and healthy natural light environment in the indoor space, in line with the green development values ​​of energy conservation and environmental protection; the main light module 7 of the present invention uses an optical kit 72 and a rotating mechanism 8 to simulate the square light spot of the sun entering through the window, and has more functions and better optical effects than existing clear sky lights on the market.

[0097] In this embodiment, the fifth position is the end position of the track 51, the fifth color temperature is preferably 1500K, and the fifth luminous flux is preferably 60lm, but this is not a limitation and can be set according to actual conditions.

[0098] 6. Night Mode

During the movement, the color temperature of the solar module 4 is the preset sixth color temperature and the luminous flux is the preset sixth luminous flux. After the movement is completed, the solar module 4 is turned off.

[0100] In the night mode, the solar light source in the solar module 4 can be switched from the "sun state" to the "moon state".

[0101] In this embodiment, the sixth color temperature is preferably 4000K, and the sixth luminous flux is preferably 30.10 lm, but this is not a limitation and can be set according to actual conditions.

[0102] It should be noted that the values ​​of the first color temperature, the second color temperature, the third color temperature, the fourth color temperature, the fifth color temperature, the sixth color temperature, the first luminous flux, the second luminous flux, the third luminous flux, the fourth luminous flux, the fifth luminous flux, and the sixth luminous flux can be set according to the trend of natural sunlight. Generally, the first color temperature, the second color temperature, the sixth color temperature, the fourth color temperature, and the third color temperature increase in sequence, the first color temperature and the fifth color temperature are equal, and the first luminous flux, the sixth luminous flux, the fifth luminous flux, the second luminous flux, the fourth luminous flux, and the third luminous flux increase in sequence. In this embodiment, the color temperature and luminous flux values ​​corresponding to the early morning mode, the morning mode, the noon mode, the afternoon mode, the evening mode, and the night mode are shown in Table 1 below:

[0103] Table 1

[0104] Mode Information Color temperature (K) Luminous flux (lm) Morning Mode 1500 30 Morning Mode 3500 557.22 Noon Mode 6500 1507.80 Afternoon Mode 5700 1072.80 Evening mode 1500 60 Night Mode 4000 30.10

[0105] 7. Rhythmic Pattern

[0106] In the rhythm mode, the morning mode, the morning mode, the noon mode, the afternoon mode, the evening mode, and the night mode are performed according to the real time.

[0107] In this embodiment, the rhythm mode operation cycle is 24 hours, wherein the real-time time corresponding to the early morning mode is 6:00, the real-time time corresponding to the morning mode is 9:00, the real-time time corresponding to the noon mode is 12:00, the real-time time corresponding to the afternoon mode is 15:00, the real-time time corresponding to the evening mode is 18:00, and the real-time time corresponding to the night mode is 20:00, but this is not a limitation and can be set according to actual conditions.

[0108] Accordingly, during the transition process between the early morning mode, the morning mode, the noon mode, the afternoon mode, the evening mode and the night mode, the position of the solar module 4 gradually changes according to the preset rhythmic trajectory movement speed, the color temperature gradually changes according to the preset rhythmic color temperature change speed, and the luminous flux gradually changes according to the preset rhythmic luminous flux change speed.

[0109] For example, the transition period between the early morning mode and the morning mode is from 6:00 to 9:00. During this transition period, the solar module 4 gradually moves from the first position to the second position at a constant speed or a variable speed, the color temperature gradually changes from 1500K to 3500K at a constant speed or a variable speed, and the luminous flux gradually changes from 30lm to 557.22lm at a constant speed or a variable speed.

[0110] 8. Demonstration Mode

[0111] In the demonstration mode, the early morning mode, the morning mode, the noon mode, the afternoon mode, the evening mode and the night mode are executed in sequence according to a preset execution rate.

[0112] In this embodiment, the demonstration mode operation period is 1 minute.

[0113] Accordingly, during the transition process between the early morning mode, the morning mode, the noon mode, the afternoon mode, the evening mode and the night mode, the position of the solar module 4 gradually changes according to the preset demonstration trajectory movement speed, the color temperature gradually changes according to the preset demonstration color temperature change speed, and the luminous flux gradually changes according to the preset demonstration luminous flux change speed.

[0114] It should be noted that the demonstration mode is theoretically an accelerated running effect of the rhythm mode, but in fact some adjustments have been made to ensure a comfortable transition; that is, under normal circumstances, the rhythm mode is a linear gradual transition, while the demonstration mode is a nonlinear gradual transition.

[0115] 9. Light on mode

[0116] In light on mode, turn on the power.

[0117] 10. Lights off mode

[0118] In the light-off mode, the power is turned off so that the solar module 4 and the moving mechanism 5 are turned off.

[0119] 11. Pause Mode

[0120] In the pause mode, the current color temperature, current luminous flux and current position of the solar module 4 are kept unchanged.

[0121] For example, when the solar module 4 is executing the rhythm mode / demonstration mode, when the pause mode is started, the rhythm mode / demonstration mode can be stopped, that is, the output effect remains at the moment when the pause rhythm button is pressed. When the pause rhythm button is pressed again, the rhythm mode / demonstration mode will continue to run.

[0122] Therefore, the present invention can make the solar module 4 move intelligently in different time periods and adjust the corresponding color temperature at the same time, thereby more realistically simulating real sun spots and achieving a natural effect of alternating morning and evening.

[0123] In actual applications, a control signal (e.g., a mode signal) can be sent to the main control unit 63 by pressing the corresponding mode button on the remote control. The main control unit 63 then outputs a PWM signal to the DC-DC solar power sub-unit and the DC-DC mobile power sub-unit after internal processing. The DC-DC solar power sub-unit adjusts the color temperature and luminous flux of the solar module 4 according to the PWM signal, and the DC-DC mobile power sub-unit adjusts the moving speed of the mobile module according to the PWM signal, thereby achieving sun-like spots in different scenarios.

[0124] See also Figure 14 , Figure 14 A flow chart of a second embodiment of the rhythm control method based on a clear sky lamp of the present invention is shown, which includes:

[0125] S201, acquiring mode information in real time;

[0126] S202, driving the moving mechanism 5 in real time according to the mode information to adjust the position of the solar module 4 in real time;

[0127] S203: Adjust the solar state parameters of the solar module 4 in real time according to the mode information.

[0128] S204, adjusting the rotating mechanism 8 in real time according to the mode information to adjust the illumination angle of the main light module 7 in real time;

[0129] S205 , adjusting the main state parameters of the main optical module 7 in real time according to the mode information.

[0130] It should be noted that there is no necessary order between steps S202 to S205. While step S202 is being performed, step S203, step S203 and step S205 can also be performed.

[0131] and Figure 10The difference from the first embodiment shown is that the clear sky lamp in this embodiment further includes a main light module 7 and a rotating mechanism 8; accordingly, this embodiment also adjusts the solar state parameters and the irradiation angle of the solar module 4 according to the mode information (see Figure 10 ), where the main state parameters include color temperature, luminous flux and on / off state, but are not limited to these and can be set according to actual conditions.

[0132] In the morning mode, the illumination angle of the main light module 7 is a preset first angle. In this embodiment, the first angle is preferably 5 degrees, but it is not limited thereto and can be set according to actual conditions.

[0133] In the morning mode, the illumination angle of the main light module 7 is a preset second angle. In this embodiment, the first angle is preferably 35 degrees, but it is not limited thereto and can be set according to actual conditions.

[0134] In the noon mode, the illumination angle of the main light module 7 is a preset third angle. In this embodiment, the first angle is preferably 50 degrees, but it is not limited thereto and can be set according to actual conditions.

[0135] In the afternoon mode, the illumination angle of the main light module 7 is a preset fourth angle. In this embodiment, the first angle is preferably 35 degrees, but is not limited thereto and can be set according to actual conditions.

[0136] In the evening mode, the main light module 7 is turned off.

[0137] In night mode, the main light module 7 is turned off.

[0138] It should be noted that the values ​​of the first angle, the second angle, the third angle, and the fourth angle can be set according to the trend of the natural sun; generally, the first angle, the second angle, and the third angle increase in sequence, and the second angle and the fourth angle are equal. In this embodiment, the color temperature, luminous flux, and illumination angle values ​​corresponding to the early morning mode, the morning mode, the noon mode, the afternoon mode, the evening mode, and the night mode are shown in Table 2 below:

[0139] Table 2

[0140] Mode Information Color temperature (K) Luminous flux (lm) Irradiation angle (deg) Morning Mode 1500 30 5 Morning Mode 3500 557.22 35 Noon Mode 6500 1507.80 50 Afternoon Mode 5700 1072.80 35 Evening mode 1500 60 / Night Mode 4000 30.10 /

[0141] Similarly, in the rhythmic mode, during the transition between the early morning mode, the morning mode, the noon mode, the afternoon mode, the evening mode and the night mode, the illumination angle of the main light module 7 gradually changes according to the preset rhythmic angle change speed;

[0142] For example, the transition period between the early morning mode and the morning mode is from 6:00 to 9:00. During this transition period, the solar module 4 gradually moves from the first position to the second position at a uniform speed or a variable speed, the color temperature gradually changes from 1500K to 3500K at a uniform speed or a variable speed, and the luminous flux gradually changes from 30lm to 557.22lm at a uniform speed or a variable speed; at the same time, the illumination angle of the main light module 7 gradually changes from 5 degrees to 35 degrees at a uniform speed or a variable speed.

[0143] Similarly, in the demonstration mode, during the transition process between the early morning mode, the morning mode, the noon mode, the afternoon mode, the evening mode and the night mode, the illumination angle of the main light module 7 gradually changes according to the preset demonstration angle change speed.

[0144] Furthermore, the present invention can also adjust the blue sky state parameters of the blue sky light module in real time according to the mode information, wherein the blue sky state parameters include color temperature, luminous flux and on / off state, but are not limited to these and can be set according to actual conditions.

[0145] Therefore, the present invention controls the blue sky module 3, the sun module 4, and the main light module 7 by sending mode signals to achieve rhythmic adjustment of color temperature, luminous flux, the position of the main light source 73, and the angle of sunlight, thereby simulating the real effect of the sky.

[0146] 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.
