Description

Technical Field

[0001] This utility model relates to the field of blue sky light design, and more particularly to a blue sky light module. Background Technology

[0002] With economic development and improved living standards, a healthy living environment has become a popular pursuit. For lighting fixtures, simulating natural light is the biggest challenge. In this context, the Skylight Lamp has emerged, designed to simulate the visual effect of the sky, providing a skylight-like illumination for indoor spaces that cannot be reached by sunlight.

[0003] Most existing sky lights use a light source to obliquely illuminate a Rayleigh diffuser to achieve a simulated sky visual effect. However, the blue sky effect presented by this method is rather hazy and it is difficult to achieve a clear, sunny sky effect. In addition, the lights are relatively large in size, occupying a lot of space and making them inconvenient to install. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a blue sky light module that utilizes an ultra-thin panel to simulate various natural light effects, allowing users to experience the changing natural rhythms indoors and enhancing the user experience.

[0005] To address the aforementioned technical problems, this utility model provides a blue sky light module, comprising a module housing, a Rayleigh scattering plate, a first light source, and a second light source. The module housing has a receiving cavity for accommodating the Rayleigh scattering plate and a light source fixing part for fixing the first light source and the second light source. Both the first light source and the second light source are located on the side of the Rayleigh scattering plate. The color temperature of the first light source is higher than that of the second light source.

[0006] As an improvement to the above scheme, the first light source is positioned facing one side of the Rayleigh scattering plate, and the second light source is positioned facing the other side of the Rayleigh scattering plate.

[0007] As an improvement to the above scheme, the first light source is positioned facing one side of the Rayleigh scattering plate, and the second light source is positioned above the first light source and facing the light-emitting surface of the Rayleigh scattering plate.

[0008] As an improvement to the above solution, the second light source is mounted on a rotating lamp holder, which is connected to a motor via a rotating shaft; the light emitted by the second light source can spread from the side of the Rayleigh diffuser plate where the first light source is mounted to the other side as the rotating lamp holder swings.

[0009] As an improvement to the above solution, the second light source includes an LED light source, and the surface of the LED light source is provided with a lens.

[0010] As an improvement to the above solution, the light source fixing part includes a side plate extending upward from the bottom surface of the module housing, and the first light source and / or the second light source are disposed on the inner surface of the side plate; the receiving cavity includes a pressure plate extending laterally from the top of the side plate toward the Rayleigh scattering plate, and adjacent pressure plates have a preset light transmission gap.

[0011] As an improvement to the above solution, the light source fixing part further includes a connecting plate extending outward from the back of the side plate, a vertical plate extending upward from the edge of the connecting plate, and a light shielding plate bending horizontally inward from the top of the vertical plate. The second light source is located at the junction of the vertical plate and the light shielding plate.

[0012] As an improvement to the above solution, the lens includes a trapezoidal body, the bottom surface of which is the light-emitting surface; the top of the trapezoidal body is provided with a groove, the bottom surface of which is an outwardly protruding light-incident arc surface; the light-incident arc surface is directly opposite the LED light source.

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

[0014] Accordingly, this utility model embodiment also provides a method for adjusting the blue sky rhythm. It utilizes a first light source positioned on the side of a Rayleigh scattering plate, in conjunction with a second light source emitting light towards the front or side of the Rayleigh scattering plate. 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 changing over time effect on the Rayleigh scattering plate. Specifically: the first light source positioned on the side of the Rayleigh scattering plate emits light with a color temperature of 5000K-12000K, causing the front of the Rayleigh scattering plate to emit blue light outwards, creating a blue sky effect; the second light source positioned on the side of the Rayleigh scattering plate emits light with a color temperature of 800K-2700K, causing the Rayleigh scattering plate to emit light towards the front or side of the Rayleigh scattering plate, creating a blue sky effect. The front of the Rayleigh scattering plate emits orange-red light outwards, creating a sunset effect. A first light source located on the side of the Rayleigh scattering plate emits light with a color temperature of 5000K-12000K onto the Rayleigh scattering plate, while a second light source emits light with a color temperature of 800K-2700K onto the Rayleigh scattering plate, creating a mixed light effect. The second light source is moved above the first light source, so that it emits light with a color temperature of 800K-2700K directly onto the front of the Rayleigh scattering plate at a certain angle. The second light source is driven to rotate to change its illumination angle, controlling the range of the second light source illuminating the surface of the Rayleigh scattering plate, thereby simulating the change of natural sunset light with the angle of sunlight on the Rayleigh scattering plate.

[0015] Implementing the embodiments of this utility model has the following beneficial effects:

[0016] This invention's lighting device creates a deeper and more three-dimensional blue sky effect. Using only a single panel and light source, it achieves various atmospheric lighting effects, including blue skies and sunsets, significantly reducing the thickness and production cost of skylights. By placing two light sources of different color temperatures opposite each other on either side of a Rayleigh diffuser panel, the light is mixed to create different natural light effects. The ultra-thin panel can simulate various natural light effects, allowing users to experience the changing rhythms of nature indoors and enhancing the user experience.

[0017] As the light emitted by the second light source swings with the rotating lamp holder, spreading from the side of the Rayleigh diffuser with the first light source to the other side, the Rayleigh diffuser will display a gradient effect where the orange-red area gradually increases, simulating the changes in light produced when the sun gradually sets and shines on the clouds, allowing people to experience the natural rhythmic changes in light outside indoors.

[0024] 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.

[0025] Example 1

[0026] As shown in Figures 1 and 2, this embodiment provides a blue sky light module, including a module housing 1, a Rayleigh diffuser plate 2, a first light source 3, and a second light source 4. The module housing 1 has a receiving cavity 11 for accommodating the Rayleigh diffuser plate 2, and a light source fixing part 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 diffuser 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.

[0027] The first light source 3 is positioned facing one side of the Rayleigh scattering plate 2, and the second light source 4 is positioned facing the other side of the Rayleigh scattering plate 2. When the lighting fixture needs to display a clear sky effect, only the first light source 3 is lit. The light enters the Rayleigh scattering light guide plate and is scattered by the surface of the micro-nano particles inside, making its light-emitting surface appear as if it were a blue sky. When only the second light source 4 is lit, because 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 a sunset. When both light sources are lit simultaneously, the blue light and orange-red light will mix. Different atmospheric effects can be achieved by adjusting the current of the two light sources. This mixing effect has good uniformity, and no obvious color boundary can be seen on a single plate.

[0028] This invention's lighting device creates a deeper and more three-dimensional blue sky effect. Using only a single panel and light source, it achieves various atmospheric lighting effects, including blue skies and sunsets, significantly reducing the thickness and production cost of skylights. By placing two light sources of different color temperatures opposite each other on both sides of the Rayleigh diffuser panel 2, the light is mixed to create different natural light effects. The ultra-thin panel can simulate various natural light effects, allowing users to experience the changing rhythms of nature indoors and enhancing the user experience.

[0029] Preferably, the light source fixing part 12 includes a side plate 121 extending upward from the bottom surface of the module housing, and the first light source 3 and / or the second light source 4 are disposed on the inner surface of the side plate 121; the receiving cavity 11 includes a pressure plate 111 extending laterally from the top of the side plate 121 toward the Rayleigh diffuser plate 2. The above-described module housing structure can enclose the Rayleigh diffuser plate 2, the first light source 3, and the second light source 4 to form an independent module, which facilitates overall installation in the lamp, reduces the assembly process of the lamp, and also reduces the overall thickness of the lamp.

[0030] Preferably, in some embodiments, a semi-transparent, semi-reflective plate can be added below the Rayleigh diffuser plate 2. When light enters the Rayleigh diffuser plate, some of the light is refracted downwards onto the semi-transparent, semi-reflective plate, undergoing multiple reflections. This creates a visual effect of superimposed blue sky when the human eye observes the lamp, resulting in a more three-dimensional effect. Simultaneously, it 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 diffuser plate 2. The light emitted by the low color temperature LEDs contrasts with the white substrate at the bottom, making the orange-red light of the rhythmic mode more intuitive and enhancing the atmospheric effect.

[0031] Example 2

[0032] As shown in Figures 3-5, this embodiment provides a blue sky light module, including a module housing 1, a Rayleigh diffuser plate 2, a first light source 3, and a second light source 4. The module housing 1 has a receiving cavity 11 for accommodating the Rayleigh diffuser plate 2, and a light source fixing part 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 diffuser 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.

[0033] The first light source 3 is positioned facing one side of the Rayleigh scattering plate 2, and the second light source 4 is positioned above the first light source 3 and facing the light-emitting surface of the Rayleigh scattering plate 2.

[0034] Preferably, the second light source 4 is disposed on a rotating lamp holder 41, and the rotating lamp holder 41 is connected to a motor 43 via a rotating shaft 42; the light emitted by the second light source 4 can spread from the side of the Rayleigh diffuser plate 2 where the first light source 3 is disposed to the other side as the rotating lamp holder 41 swings.

[0035] When the lighting fixture needs to create a clear sky effect, only the first light source 3 is lit. The light enters the Rayleigh diffuser plate and is scattered by the micro-nano particles inside, causing the light-emitting surface to appear as if it were a blue sky. When only the second light source 4 is lit, because 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 diffuser plate, and the light-emitting surface of the plate will appear orange-red, similar to the lighting effect of a sunset. When both light sources are lit simultaneously, the blue and orange-red light will mix, and different atmospheric effects can be achieved by adjusting the current of the first and second light sources. When the light emitted by the second light source 4 spreads from the side of the Rayleigh diffuser plate 2 where the first light source 3 is located to the other side as the rotating lamp holder 41 swings, the Rayleigh diffuser plate 2 will show a gradient effect of the orange-red area gradually increasing, simulating the change in light produced when the sun gradually sets and shines on the clouds, allowing people indoors to experience the natural rhythm of light changes outside.

[0036] This invention's lighting device creates a deeper and more three-dimensional blue sky effect. Using only a single panel and light source, it achieves various ambient lighting effects, such as blue skies and sunsets, significantly reducing the thickness and production cost of skylights. By utilizing two light sources with different color temperatures to emit light onto different surfaces of the Rayleigh diffuser panel 2, and through a rotating structure, the illumination area of ​​the ambient mode is controlled to regulate the lighting effect. The light emission transition is uniform, more closely resembling a natural scene. It creates different natural light effects, and the ultra-thin panel can simulate various natural light effects, allowing users to experience the changing rhythms of nature indoors and enhancing the user experience.

[0037] Preferably, the light source fixing part 12 includes a side plate 121 extending upward from the bottom surface of the module housing 1, and the first light source 3 is disposed on the inner surface of the side plate 121; the receiving cavity 11 includes a pressure plate 111 extending laterally from the top of the side plate 121 toward the Rayleigh diffuser plate 2. The above-described module housing 1 structure can enclose the Rayleigh diffuser plate 2, the first light source 3, and the second light source 4 to form an independent module, which facilitates overall installation in the lamp, reduces the assembly process of the lamp, and also reduces the overall thickness of the lamp.

[0038] Preferably, adjacent pressure plates 111 directly have a preset light-transmitting gap 112. Some of the light emitted by the second light source 4 can enter the side of the Rayleigh diffuser plate 2 through the preset light-transmitting gap 112, and combined with the light entering from the surface of the Rayleigh diffuser plate 2, so that light of different levels is re-emitted from the surface of the Rayleigh diffuser plate 2, forming a deep light effect, which better simulates the natural lighting in the distance.

[0039] Preferably, the light source fixing part 12 further includes a connecting plate 122 extending outward from the back of the side plate 121, a vertical plate 123 extending upward from the edge of the connecting plate 122, and a light-shielding plate 124 bending horizontally inward from the top of the vertical plate 123. The second light source 4 is disposed at the junction of the vertical plate 123 and the light-shielding plate 124. The light source fixing part 12 is integrally formed by the module housing, which is beneficial for placing the second light source 4 obliquely above the Rayleigh diffuser plate 2 at a predetermined distance. At the same time, it reserves installation space for the rotating shaft 42 and the motor 43, making the entire module more compact and thinner, and able to match lamps of different shapes and sizes.

[0040] Referring to Figure 6, the second light source 4 includes an LED light source 44, and a lens 5 is provided on the surface of the LED light source 44. The lens 5 includes a trapezoidal body 51, the bottom surface of which is a light-emitting surface 52; the top of the trapezoidal body 51 is provided with a groove 53, and the bottom surface of the groove 53 is an outwardly convex light-incident arc surface 54; the light-incident arc surface 54 is directly opposite the LED light source 44. The lens 5 can concentrate the light from the light source, reduce its light-emitting angle, facilitate the control of its illumination area, and improve the utilization rate of light.

[0041] Preferably, in some embodiments, a semi-transparent, semi-reflective plate can be added below the Rayleigh diffuser plate 2. When light enters the light guide plate, some of the light is refracted downwards onto the semi-transparent, semi-reflective plate and then reflected in multiple stages. This creates a visual effect of superimposed blue sky when the human eye observes the lamp, making it more three-dimensional and improving the utilization rate of light, resulting in higher brightness of the light-emitting surface 52. Alternatively, a white diffuser plate or white reflective paper can be added below the Rayleigh diffuser plate 2. The light emitted by the low color temperature LEDs contrasts with the white substrate at the bottom, making the orange-red light of the rhythmic mode more intuitive and creating a better atmosphere.

[0042] Example 3

[0043] The third embodiment of this utility model provides a method for adjusting the blue sky rhythm. It utilizes a first light source 3 located on the side of a Rayleigh diffuser 2, in conjunction with a second light source 4 emitting light towards the front or side of the Rayleigh diffuser 2. 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 effect, and a sunset changing over time effect on the Rayleigh diffuser 2. Specifically: the first light source 3 located on the side of the Rayleigh diffuser 2 emits light with a color temperature of 5000K-12000K towards the Rayleigh diffuser 2, causing the front of the Rayleigh diffuser 2 to emit blue light outwards, creating a blue sky effect; the second light source 4 located on the side of the Rayleigh diffuser 2 emits light with a color temperature of 800K-2700K towards the Rayleigh diffuser 2, causing the Rayleigh diffuser 2 to emit blue light towards the front, creating a blue sky effect. The front of the Rayleigh diffuser 2 emits orange-red light outwards, creating a sunset effect. A first light source 3, located on the side of the Rayleigh diffuser 2, emits light with a color temperature of 5000K-12000K onto the Rayleigh diffuser 2, while a second light source 4 emits light with a color temperature of 800K-2700K onto the Rayleigh diffuser 2, creating a mixed light effect. The second light source 4 is moved above the first light source 3, so that the second light source 4 directly emits light with a color temperature of 800K-2700K onto the front of the Rayleigh diffuser 2 at a certain angle. The second light source 4 is driven to rotate to change its illumination angle, controlling the range of the second light source 4 illuminating the surface of the Rayleigh diffuser 2, so as to simulate the change of natural sunset with the angle of sunlight on the Rayleigh diffuser 2.

[0044] Using the above method, various ambient lighting effects such as blue sky and sunset can be achieved by adding a light source to a single panel, significantly reducing the thickness and production cost of the skylight lamp. Two light sources with different color temperatures emit light onto different surfaces of the Rayleigh diffuser panel 2. Simultaneously, a rotating structure controls the illumination area of ​​the ambient mode, thereby controlling the lighting effect. The light emission transition is uniform, more closely resembling a natural scene. This creates different natural light effects, allowing the ultra-thin panel to simulate various natural light effects, enabling users to experience the changing rhythms of nature indoors and enhancing the user experience.

[0045] 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.
