[0011] As an improvement of the above solution, the light source fixing part also includes a connecting plate extending outward from the back of the side panel, a vertical plate extending upward from the edge of the connecting plate, and a shading plate bent horizontally inward from the top of the vertical plate. The second light source is arranged at the intersection of the vertical plate and the shading plate.

[0013] As an improvement to the above solution, the color temperature of the first light source is 5000K-12000K, and the color temperature of the second light source is 800K-2700K.

[0014] Correspondingly, an embodiment of the present invention further provides a blue sky rhythm adjustment method, which utilizes a first light source disposed on the side of a Rayleigh scattering plate in conjunction with a second light source emitting light toward the front or side of the Rayleigh scattering plate, so that the color temperature of the first light source is greater than that of the second light source, thereby achieving a blue sky effect, a sunset effect, and a sunset effect changing with time on the Rayleigh scattering plate, wherein: the first light source disposed on the side of the Rayleigh scattering plate emits light with a color temperature of 5000K-12000K toward the Rayleigh scattering plate, so that the front of the Rayleigh scattering plate emits blue light outward, forming a blue sky effect; the second light source disposed on the side of the Rayleigh scattering plate emits light with a color temperature of 800K-2700K toward the Rayleigh scattering plate, so that the Rayleigh scattering plate The invention relates to a method for simulating a natural sunset glow on a Rayleigh scattering plate.

[0028] 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.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a blue sky light module, comprising a housing 1, a Rayleigh scattering plate 2, a first light source 3, and a second light source 4. The housing 1 is formed with a plate fixing portion 11 for fixing the Rayleigh scattering plate 2, and a light source fixing portion 12 for fixing the first light source 3 and the second light source 4. The first light source 3 and the second light source 4 are both disposed on the side of the Rayleigh scattering plate 2. The color temperature of the first light source 3 is higher than that of the second light source 4. Preferably, the color temperature of the first light source 3 is 5000K-12000K, and the color temperature of the second light source 4 is 800K-2700K.

[0031] The first light source 3 is arranged facing one side of the Rayleigh scattering plate 2, and the second light source 4 is arranged facing the other side of the Rayleigh scattering plate 2. Figure 7 As shown, when the lamp needs to show a clear sky effect, only the first light source 3 is lit, and the light enters the Rayleigh scattering light guide plate and is scattered on the surface of the micro-nano particles inside it, so that the light-emitting surface shows a blue sky effect. Figure 8 As shown, when only the second light source 4 is turned on, since the proportion of blue light in the light is too low, most of the light will not be refracted by the nano-titanium dioxide particles in the Rayleigh scattering plate, and the light-emitting surface of the plate will appear orange-red, similar to the lighting effect of the sunset. Figure 9 As shown in the figure, when both light sources are lit simultaneously, the blue light and the orange-red light will mix. By adjusting the current of the two light sources, different atmosphere effects can be achieved. This light mixing effect is highly uniform, and no obvious color boundaries can be seen on a single board.

[0032] The lighting device of this invention creates a deeper, more three-dimensional blue sky effect. Using only a single panel and light source, it achieves a variety of ambient lighting effects, including blue skies and sunsets, significantly reducing the thickness and production cost of clear sky lamps. By placing two light sources of different color temperatures on opposite sides of the Rayleigh scattering plate 2, the light blends to create different natural light effects. This ultra-thin panel can simulate a variety of natural light effects, allowing users to experience the rhythmic changes of nature indoors and enhance the user experience.

[0033] Preferably, the light source fixing portion 12 includes a side panel 121 extending upward from the bottom surface of the housing, and the first light source 3 and / or the second light source 4 are disposed on the inner surface of the side panel 121. The panel fixing portion 11 includes a pressure plate 111 extending laterally from the top of the side panel 121 toward the Rayleigh scattering plate 2. This housing structure can enclose the Rayleigh scattering plate 2, the first light source 3, and the second light source 4 to form an independent module, facilitating overall installation in the lamp, reducing the number of lamp assembly steps, and also reducing the overall thickness of the lamp.

[0034] Preferably, in some embodiments, a semi-transparent, semi-reflective plate can be added below the Rayleigh scatter plate 2. When light enters the Rayleigh scatter plate, some of the light is refracted downward onto the semi-transparent, semi-reflective plate. After multiple reflections, the human eye experiences a superimposed blue sky effect, creating a more three-dimensional effect. This also improves light utilization and increases the brightness of the light-emitting surface. Alternatively, a white diffuser plate or white reflective paper can be added below the Rayleigh scatter plate 2. The light emitted by the low-color-temperature lamp beads contrasts with the white plate at the bottom, making the orange-red rhythmic light more intuitive and creating a more ambiance-enhancing effect.

[0035] Example 2

[0036] like Figure 3-Figure 5 As shown, this embodiment provides a blue sky light module, comprising a housing 1, a Rayleigh scattering plate 2, a first light source 3, and a second light source 4. The housing 1 is formed with a plate fixing portion 11 for fixing the Rayleigh scattering plate 2, and a light source fixing portion 12 for fixing the first light source 3 and the second light source 4. The first light source 3 and the second light source 4 are both disposed on the side of the Rayleigh scattering plate 2. The color temperature of the first light source 3 is higher than that of the second light source 4. Preferably, the color temperature of the first light source 3 is 5000K-12000K, and the color temperature of the second light source 4 is 800K-2700K.

[0037] The first light source 3 is disposed opposite to one side of the Rayleigh scatter plate 2 , and the second light source 4 is disposed above the first light source 3 and toward the light-emitting surface of the Rayleigh scatter plate 2 .

[0038] Preferably, the second light source 4 is arranged on a rotating lamp holder 41, and the rotating lamp holder 41 is connected to the motor 43 through a rotating shaft 42; the light emitted by the second light source 4 can spread from one side of the Rayleigh scattering plate 2 where the first light source 3 is provided to the other side as the rotating lamp holder 41 swings.

[0039] When the lamp needs to show a clear sky effect, only the first light source 3 is lit, and the light enters the Rayleigh scattering plate and is scattered on the surface of the micro-nanoparticles inside it, making the light-emitting surface appear to have a blue sky effect. When only the second light source 4 is lit, since the proportion of blue light in the light is too low, most of the light will not be refracted by the nano-titanium dioxide particles in the Rayleigh scattering plate, and the light-emitting surface of the plate will appear orange-red, similar to the lighting effect of the sunset. When the two light sources are lit at the same time, the blue light and the orange-red light will be mixed, and different atmosphere effects can be achieved by adjusting the current of the first light source and the second light source. Figure 10 As shown, when the light emitted by the second light source 4 spreads from one side of the Rayleigh scattering plate 2 where the first light source 3 is provided to the other side as the rotating lamp holder 41 swings, the Rayleigh scattering plate 2 will present a gradient effect in which the orange-red area gradually becomes larger, simulating the light changes caused by the sun gradually setting and illuminating the clouds, allowing people indoors to experience the natural rhythmic light changes of the outside world.

[0040] The lighting device of the present invention creates a deeper, more three-dimensional blue sky effect. Using only a single panel and light source, it achieves a variety of ambient lighting effects, including blue skies and sunsets, significantly reducing the thickness and production cost of clear sky lamps. Two light sources with different color temperatures illuminate different surfaces of the Rayleigh scattering plate 2. A rotating structure simultaneously controls the illumination area of the ambient mode to control the lighting effect. The resulting light output transitions evenly, more closely resembling a natural scene. This creates distinct natural light effects, enabling the ultra-thin panel to simulate a variety of natural light effects, allowing users to experience the natural rhythm of the seasons indoors and enhancing the user experience.

[0041] Preferably, the light source fixing portion 12 includes a side panel 121 extending upward from the bottom surface of the housing 1, and the first light source 3 is disposed on the inner surface of the side panel 121. The panel fixing portion 11 includes a pressure plate 111 extending laterally from the top of the side panel 121 toward the Rayleigh scattering plate 2. This structure of the housing 1 can enclose the Rayleigh scattering plate 2, the first light source 3, and the second light source 4 to form an independent module, facilitating overall installation in the lamp, reducing the number of assembly steps, and reducing the overall thickness of the lamp.

[0042] Preferably, adjacent pressing plates 111 have preset light-transmitting gaps 112. A portion of the light emitted by the second light source 4 can enter the side of the Rayleigh scatter plate 2 through the preset light-transmitting gaps 112. Combined with the light entering from the surface of the Rayleigh scatter plate 2, different levels of light are re-emitted from the surface of the Rayleigh scatter plate 2, creating a deep light effect that better simulates natural light from a distance.

[0043] Preferably, the light source fixing portion 12 further includes a connecting plate 122 extending outward from the back of the side panel 121, a vertical plate 123 extending upward from the edge of the connecting plate 122, and a light shielding plate 124 curved horizontally inward from the top of the vertical plate 123. The second light source 4 is disposed at the intersection of the vertical plate 123 and the light shielding plate 124. The light source fixing portion 12 is integrally formed with the housing, facilitating placement of the second light source 4 at a predetermined distance obliquely above the Rayleigh scattering plate 2. Space is also reserved for the installation of the rotating shaft 42 and the motor 43, making the entire module more compact and thin, and compatible with lamps of various shapes and sizes.

[0044] Combine Figure 6 As shown, the second light source 4 includes an LED light source 44, with a lens 5 disposed on its surface. The lens 5 comprises a trapezoidal body 51, the bottom surface of which serves as a light-emitting surface 52. A groove 53 is disposed on the top of the trapezoidal body 51, the bottom surface of which serves as an outwardly protruding light-entering arc surface 54. The light-entering arc surface 54 directly faces the LED light source 44. The lens 5 can converge the light from the light source, reducing its light-emitting angle, facilitating control of the area illuminated, and improving light utilization.

[0045] Preferably, in some embodiments, a translucent, semi-reflective plate can be added below the Rayleigh scatter plate 2. When light enters the light guide plate, some of the light is refracted downward onto the translucent, semi-reflective plate, where it undergoes multiple reflections. This creates a visual effect of a superimposed blue sky when the human eye observes the lamp, creating a more three-dimensional effect. This also improves light utilization and increases the brightness of the light-emitting surface 52. Alternatively, a white diffuser plate or white reflective paper can be added below the Rayleigh scatter plate 2. The light emitted by the low-color-temperature lamp beads contrasts with the white plate at the bottom, making the orange-red rhythmic light more intuitive and creating a more ambiance-enhancing effect.

[0046] Example 3

[0047] A third embodiment of the present invention provides a blue sky rhythm adjustment method, which utilizes a first light source 3 disposed on the side of a Rayleigh scattering plate 2 in conjunction with a second light source 4 emitting light toward the front or side of the Rayleigh scattering plate 2, so that the color temperature of the first light source 3 is greater than that of the second light source 4, thereby achieving a blue sky effect, a sunset glow effect, and a sunset glow effect that changes over time on the Rayleigh scattering plate 2, wherein: the first light source 3 disposed on the side of the Rayleigh scattering plate 2 emits light with a color temperature of 5000K-12000K toward the Rayleigh scattering plate 2, so that the front of the Rayleigh scattering plate 2 emits blue light outward, forming a blue sky effect; the second light source 4 disposed on the side of the Rayleigh scattering plate 2 emits light with a color temperature of 800K-2700K toward the Rayleigh scattering plate 2, so that the Rayleigh scattering plate 2 The system emits orange-red light outward from the front to create a sunset glow effect. A first light source 3 disposed on the side of a Rayleigh scatter plate 2 emits light with a color temperature of 5000K-12000K toward the Rayleigh scatter plate 2, while a second light source 4 simultaneously emits light with a color temperature of 800K-2700K toward the Rayleigh scatter plate 2, thereby creating a mixed light effect on the Rayleigh scatter plate 2. The second light source 4 is moved above the first light source 3 so that it directly emits light with a color temperature of 800K-2700K toward the front of the Rayleigh scatter plate 2 at a certain angle. The second light source 4 is driven to rotate to change its illumination angle, and the range of illumination of the second light source 4 on the surface of the Rayleigh scatter plate 2 is controlled to simulate the natural sunset glow on the Rayleigh scatter plate 2 as the angle of sunlight changes.

[0048] Using this method, a single panel and light source can achieve a variety of ambient lighting effects, such as blue skies and sunsets, significantly reducing the thickness and production cost of clear sky lamps. Two light sources with different color temperatures illuminate different surfaces of the Rayleigh scattering plate 2. A rotating structure simultaneously controls the illumination area of the ambient mode to control the lighting effect. The resulting light output transitions evenly, more closely resembling natural scenes. This creates distinct natural light effects, allowing users to simulate a variety of natural lighting effects using an ultra-thin panel, allowing them to experience the natural rhythm of the circadian rhythm indoors and enhance the user experience.

[0049] 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.
