Description

Technical Field

[0001] This invention relates to the field of lighting technology, and particularly to a mirror lighting device and a method for adjusting the lighting effect of the mirror lighting device. Background Technology

[0002] Traditional mirror lighting devices, limited by their functional positioning and technical design, have long focused on basic lighting to aid imaging. Their lighting system design logic revolves around uniform supplemental lighting, making it difficult to support the refined simulation of natural, realistic lighting scenes. However, with the continuous development of lighting technology, users' demand for immersive lighting to aid imaging, such as blue skies and white clouds, sunsets, and tranquil moonlit nights, is growing, yet this demand remains unmet. Even some existing mid-to-high-end products that include ambient lighting functions still have significant limitations in their light source structure. They often employ simple side light sources or simple zoned light emission designs based on fixed boundaries, only able to adjust the overall color temperature and brightness through a single drive module. This lack of ability to achieve localized differential control of light results in a failure to accurately reproduce different lighting scenes, falling far short of the texture of natural, realistic lighting. Users cannot obtain an immersive experience in front of mirror lighting devices. Summary of the Invention

[0013] To solve the above-mentioned technical problems, the present invention provides another technical solution as follows: a method for adjusting the lighting type of a mirror lighting device, the mirror lighting device including a base, a light-emitting component, a control component, and a mirror body, wherein a receiving space is formed between the base and the mirror body, the light-emitting component is disposed within the receiving space, the control component is electrically connected to the light-emitting component, the mirror body is provided with a light-transmitting part, the light-emitting surface of the light-emitting component and the light-transmitting part are arranged sequentially in a direction away from the base, the light-emitting component includes multiple independently controlled light-emitting pixel units, and the method for adjusting the lighting type of the mirror lighting device includes the following steps: obtaining a lighting type adjustment command, the adjustment command including target lighting type information; based on the target lighting type information, the control component retrieves a corresponding optical control parameter group from a preset parameter library; the control component adjusts the optical control parameters of each light-emitting pixel unit according to the optical control parameter group, the light-emitting pixel unit emits light matching the target lighting type, and the light is emitted through the light-transmitting part.

[0014] Compared with the prior art, the mirror lighting device and the method for adjusting the lighting style of the mirror lighting device provided by the present invention have the following beneficial effects: 1. This invention provides a mirror lighting device, comprising a base, a light-emitting component, a control component, and a mirror body. A receiving space is formed between the base and the mirror body. The light-emitting component is disposed within the receiving space. The control component is electrically connected to the light-emitting component. The mirror body has a light-transmitting portion. The light-emitting surface and the light-transmitting portion of the light-emitting component are arranged sequentially away from the base. The light-emitting component includes multiple independently controllable light-emitting pixel units. The control component adjusts the optical control parameters of each light-emitting pixel unit, causing the light-emitting component to emit light corresponding to a preset lighting scene type. The light is emitted through the light-transmitting portion. By setting the light-emitting component to include multiple independently controllable light-emitting pixel units, with the light-emitting surface and the light-transmitting portion arranged sequentially away from the base, and the light-emitting pixel units disposed on the back side of the light-transmitting portion, the light from the light-emitting pixel units can pass through and be emitted from the back side of the light-transmitting portion. By using the control component to independently and differentially adjust the optical control parameters of each light-emitting pixel unit, the problem of traditional devices being unable to present natural and realistic lighting scenes through localized differential control of light is solved. By precisely controlling the optical characteristics such as light color and brightness at different positions of the light-transmitting part through each light-emitting pixel unit of the light-emitting component, different complex lighting scenes can be simulated in a refined manner, providing users with a highly realistic and immersive lighting experience, and meeting users' needs for refined ambient lighting scenes of high-quality mirror lighting devices.

[0015] 2. The optical control parameters in this embodiment of the invention include color temperature and brightness. In the light scene simulation of the mirror lighting device, color temperature and brightness are the core optical control parameters of the mirror lighting device. By independently controlling the color temperature and brightness of each light-emitting pixel unit, the mirror lighting device can simultaneously achieve precise shaping of local areas in both color atmosphere and light-dark contrast, simulating the layers and gradient effects of different complex light scenes, thereby enhancing the realism and three-dimensionality of the light scene reproduction.

[0016] 3. In this embodiment of the invention, at least one of the optical control parameters, such as spectral power distribution parameter, color temperature change gradient, brightness change gradient, color temperature change rate, and brightness change rate, is further introduced, expanding the dimensions of light control and increasing the precision of the lighting effect. Spectral power distribution (SPD) refers to the functional relationship between the spectral density of a light source and its wavelength, describing the power distribution of light in different wavelength bands and reflecting the spectral composition characteristics of light (such as the power peak of a specific band, the power ratio of each band, etc.). Color temperature change gradient refers to the change in color temperature of a preset neighborhood of luminescent pixel units in the spatial dimension, used to reflect the drastic change in color temperature of the luminescent pixel units, and presenting a corresponding color temperature gradient amplitude in the lighting effect (such as the color temperature gradient amplitude of the blue sky from low to high altitude). Brightness change gradient refers to the change in brightness of a preset neighborhood of luminescent pixel units in the spatial dimension, used to reflect the brightness of the luminescent pixel units. The degree of change is reflected in the lighting effect as a corresponding brightness gradient (e.g., the brightness gradient from the center to the edge of a cloud); the color temperature change rate refers to the amount of color temperature change of a luminous pixel unit per unit time, reflecting how fast the color temperature of the luminous pixel unit changes dynamically, and is reflected in the lighting effect as a corresponding color temperature gradient over time (e.g., the rate of color temperature decrease from orange-red to deep blue in the sunset); the brightness change rate refers to the amount of brightness change of a luminous pixel unit per unit time, reflecting how fast the brightness of the luminous pixel unit changes dynamically, and is reflected in the lighting effect as a corresponding brightness gradient over time (e.g., the rate of brightness increase from dim to bright at dawn). Since the true color of natural light originates from its specific spectral power distribution, by controlling the spectral power distribution, the true color components of specific natural light can be reproduced more accurately. By controlling the color temperature change gradient and / or brightness change gradient, the natural gradation of light in space is simulated, enhancing the color realism and spatial layering of the lighting effect, making the simulation effect closer to real natural light. By controlling the rate of color temperature change and / or the rate of brightness change, the dynamic process of soft transition of light in natural scenes can be simulated in the time dimension, such as the passing of clouds or the process of sunset. This makes the generated scene no longer a rigid, static pattern, but a light and shadow performance full of dynamic details and realistic texture, further enhancing the sense of immersion.

[0017] 4. In this embodiment of the invention, when the light-emitting component emits light corresponding to a preset lighting scene type, multiple independently controlled light-emitting pixel units form a single optical feature partition; or, multiple independently controlled light-emitting pixel units form at least two optical feature partitions. The color temperature change gradient of the light-emitting pixel units within the same optical feature partition is less than the color temperature change gradient of the light-emitting pixel units between different optical feature partitions; the brightness change gradient of the light-emitting pixel units within the same optical feature partition is less than the brightness change gradient of the light-emitting pixel units between different optical feature partitions. The optical effects of each light-emitting pixel unit within a single optical feature partition are relatively similar. The formation of a single optical feature partition by multiple independently controlled light-emitting pixel units is applicable to lighting scene types with a large area of ​​uniform optical tone. Multiple independently controlled luminescent pixel units form at least two optical feature zones. By defining the optical feature zones and constraining the color temperature and brightness variation gradients within and between the optical feature zones, the problem of rigidity in simple zone design is solved. Smaller variation gradients can be set in areas requiring smooth transitions (such as the same area simulating the sky) to achieve soft and uniform lighting effects, while larger variation gradients are allowed between different optical feature zones (such as the boundary between blue sky and white clouds) to form clear light and shadow contours. This zone strategy can collaboratively achieve clear macroscopic light and shadow structure division and soft microscopic light transitions on a single mirror illumination device, thereby efficiently and realistically constructing a detailed light and shadow image.

[0018] 5. In this embodiment of the invention, multi-color LEDs, namely red LEDs, green LEDs, and blue LEDs; or red LEDs, green LEDs, blue LEDs, and white LEDs; or a combination of red LEDs, green LEDs, and blue LEDs, and at least one of yellow LEDs, ice-blue LEDs, pure white LEDs, and warm white LEDs, are used as light-emitting pixel units. The light emission ratio and driving current are adjusted to achieve independent control of color temperature and brightness. This gives the mirror lighting device a high degree of freedom in color expression and precise brightness control. The RGB three-primary-color principle can mix to produce extremely rich colors, and adding white LEDs further improves the luminous efficiency and color performance in the high color temperature range, enabling the mirror lighting device to cover a wide color temperature range and ensuring excellent color consistency at all brightness levels. Adding at least one of yellow LEDs, ice-blue LEDs, pure white LEDs, and warm white LEDs makes the emitted colors more balanced and rich. Furthermore, LED chips are relatively inexpensive, reducing manufacturing costs while ensuring lighting effects.

[0019] 6. In this embodiment of the invention, the partitioning ensures that the mirror imaging area and the light-transmitting illumination area do not interfere with each other, and their functions are clearly defined. The mirror surface retains the imaging properties of the mirror body, ensuring a clear mirror effect when the user looks in the mirror, while the light-transmitting part serves as an independent light output area, adaptable to the control requirements of the light-emitting components, presenting the color and brightness characteristics of the scene. Furthermore, the use of a semi-reflective, semi-transparent coating layer allows the mirror surface to also be a light-transmitting part, expanding the illumination area of ​​the surface light source. This allows background light to radiate through a larger area while the user looks in the mirror, achieving a seamless integration of mirror imaging and ambient lighting, creating a more realistic and natural lighting environment, and further enhancing the user's immersive experience.

[0020] 7. In this embodiment of the invention, by setting a light-diffusing element, the problem of uneven light distribution among multiple independent light-emitting pixel units is effectively solved. The light-diffusing element can scatter and mix the light emitted by each light-emitting pixel unit, eliminate the point light source characteristics of a single LED, avoid the graininess of the surface light source formed by multiple independent light-emitting pixel units, make the emitted light softer and more uniform, form a continuous and natural light scene, avoid the destruction of the realism of the light scene by discrete light sources, thereby improving the quality of the final emitted light and ensuring that the simulated light scene has a smooth and delicate visual effect.

[0021] 8. In this embodiment of the invention, by quantitatively limiting the number and individual area of ​​the luminescent pixel units, the spatial resolution and detail of the lighting simulation are ensured to be sufficiently high. A number of luminescent pixel units greater than or equal to 10 means that the lighting scene can be divided and controlled in a more detailed manner, and the luminescent area of ​​a single luminescent pixel unit is less than or equal to 1 cm². 2 This means that the light output of each luminous pixel unit is more concentrated, which can depict more delicate light and shadow details. The combination of the two enables the mirror lighting device to create high-quality light and shadow patterns with clear boundaries and delicate transitions, avoiding the problem of rough and blurry light and shadow caused by the luminous pixel unit having too large an area or too few units.

[0022] 9. In this embodiment of the invention, by specifically defining the color temperature and brightness parameter ranges of each optical feature zone under different lighting scene types, a direct and operable quantitative scheme is provided for achieving high-fidelity reproduction of several typical natural lighting scenes. The first lighting scene type is a blue sky and white clouds scene, with the first optical feature zone being the core area of ​​the high-altitude blue sky, the second optical feature zone being the transition area of ​​the low-altitude blue sky, and the third optical feature zone being the white cloud area; the second lighting scene type is a sunset and evening glow scene, with the fourth optical feature zone being the core area surrounding the sunset, the fifth optical feature zone being the red-orange area of ​​the evening glow, and the sixth optical feature zone being the afterglow transition area; the third lighting scene type is a lush green grassland scene, with the seventh optical feature zone being the grass and green leaf area, and the eighth optical feature zone being the flower highlight area. These parameter ranges are based on specific settings of the physical optical characteristics of real lighting scenes, enabling the creation of specific atmospheric lighting scenes with a high degree of immersion.

[0023] 10. The present invention also provides a method for adjusting the lighting type of a mirror lighting device. The method for adjusting the lighting type of a mirror lighting device has the same beneficial effects as the above-mentioned mirror lighting device, and will not be described again here.

[0037] 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 and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0040] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0041] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0042] Please combine Figure 1 and Figure 2 The first embodiment of the present invention provides a mirror lighting device 1, which includes a base 10, a light-emitting component 20, a control component 30, and a mirror body 40. A receiving space 50 is formed between the base 10 and the mirror body 40. The light-emitting component 20 is disposed in the receiving space 50. The control component 30 is electrically connected to the light-emitting component 20. The mirror body 40 is provided with a light-transmitting part 41. The light-emitting surface 24 and the light-transmitting part 41 of the light-emitting component 20 are arranged sequentially in a direction away from the base 10. The light-emitting component 20 includes a plurality of independently controlled light-emitting pixel units 21. The control component 30 adjusts the optical control parameters of each light-emitting pixel unit 21 so that the light-emitting component 20 emits light corresponding to a preset lighting scene type. The light is emitted through the light-transmitting part 41.

[0043] Understandably, by setting the light-emitting component 20 to include multiple independently controllable light-emitting pixel units 21, with the light-emitting surface 24 and the light-transmitting part 41 of the light-emitting component 20 arranged sequentially in a direction away from the base 10, and the light-emitting pixel units 21 located on the back of the light-transmitting part 41, the light from the light-emitting pixel units 21 can pass through and be emitted from the back of the light-transmitting part 41. The control component 30 independently and differentially adjusts the optical control parameters of each light-emitting pixel unit 21, solving the problem that traditional devices cannot present natural and realistic lighting scenes through localized differential control of light. The light-emitting component 20 includes multiple independently controllable light-emitting pixel units 21, meaning that the control component 30 can adjust the optical control parameters for any one of the light-emitting pixel units 21. By precisely controlling the optical characteristics such as light color and brightness at different positions of the light-transmitting part 41 through each light-emitting pixel unit 21 of the light-emitting component 20, different complex lighting scenes can be finely simulated, providing users with a highly realistic and immersive lighting experience, and meeting users' needs for refined ambient lighting scenes in a high-quality mirror lighting device 1.

[0044] It should be noted that, compared to existing ambient lights that emit light from the side, the light-emitting surface 24 and the light-transmitting part 41 of the light-emitting component 20 are arranged sequentially along the direction away from the base 10. The light-emitting pixel unit 21 is located on the back of the light-transmitting part 41, so that multiple light-emitting pixel units 21 form a surface light source. The light from the light-emitting pixel unit 21 can pass directly through and be emitted from the back of the light-transmitting part 41, resulting in higher light efficiency and accurate reproduction of the delicate effects of natural light. In contrast, side-emitting light relies on the diffusion of light after reflection inside the device. During the reflection process, optical parameters are prone to shift, and the side light source is limited by the thinness of the device, making it difficult to achieve surface pixel-level control. It can only create a blurry overall atmosphere and cannot reproduce the details of the light scene. From a visual perspective, back-transmission makes the light-transmitting part 41 a planar light-emitting body. Light is emitted evenly from the light-transmitting part 41, presenting a large-area, boundless immersive feeling of natural light. Moreover, the angle of light incidence is closer to the human eye's perception of natural light, making it less prone to glare. Side-emitting light, on the other hand, is prone to unevenness due to the limited position of the light source, resulting in bright edges and dark centers. The integration of light with the mirror imaging area is low, which can easily create a jarring feeling of separation between the ambient light and the mirror.

[0045] Optionally, please refer to Figure 3In one specific embodiment, the mirror lighting device 1 is equipped with a contact-type lighting control switch 43, which is electrically connected to the control component 30. The user selects a preset lighting type by operating the contact-type lighting control switch 43. In another specific embodiment, the mirror lighting device 1 is equipped with a remote-controlled lighting control switch 44, which is electrically connected to the control component 30. The user selects a preset lighting type by using a remote control 2 to control the remote-controlled lighting control switch 44. In yet another specific embodiment, the mirror lighting device 1 is equipped with an environmental parameter sensor 45, which is electrically connected to the control component 30. The control component 30 selects a preset lighting type based on the parameters sensed by the environmental parameter sensor 45.

[0046] Optionally, the mirror lighting device 1 is circular, rectangular or irregular in shape; the light-emitting component 20 and the corresponding light-transmitting part 41 are disposed at the upper, lower, left, right or middle part of the mirror lighting device 1.

[0047] Optionally, the arrangement of the multiple independently controllable light-emitting pixel units 21 can be either an array arrangement or a non-uniform arrangement.

[0048] Please combine Figure 1 and Figure 2 Furthermore, optical control parameters include color temperature and brightness.

[0049] Understandably, in the light scene simulation of the mirror lighting device 1, color temperature and brightness are the core optical control parameters of the mirror lighting device 1. By independently controlling the color temperature and brightness of each light-emitting pixel unit 21, the mirror lighting device 1 can simultaneously achieve precise shaping of local areas in both color atmosphere and light-dark contrast, simulating different complex light scene layers and gradient effects, thereby enhancing the realism and three-dimensionality of the light scene reproduction.

[0050] Please continue to combine Figure 1 and Figure 2 Furthermore, the optical control parameters also include at least one of the following: spectral power distribution parameters, color temperature change gradient, brightness change gradient, color temperature change rate, and brightness change rate.

[0051] Understandably, by introducing at least one of the optical control parameters such as spectral power distribution, color temperature gradient, brightness gradient, color temperature rate of change, and brightness rate of change, the dimensions of light manipulation are expanded, and the precision of the lighting effect is increased. Spectral power distribution (SPD) refers to the functional relationship between the spectral density of a light source and its wavelength, describing the power distribution of light in different wavelength bands and reflecting the spectral composition characteristics of light (such as the power peak of a specific band and the power proportion of each band). Color temperature gradient refers to the change in color temperature of the luminous pixel unit 21 within a preset neighborhood in the spatial dimension, used to reflect the drastic change in color temperature of the luminous pixel unit 21, and presenting the corresponding color temperature gradient amplitude in the lighting effect (such as the color temperature gradient amplitude of the blue sky from low to high altitude). Brightness gradient refers to the change in brightness of the luminous pixel unit 21 within a preset neighborhood in the spatial dimension, used to reflect the brightness of the luminous pixel unit 21. The degree of change is reflected in the lighting effect as a corresponding brightness gradient (e.g., the brightness gradient from the center to the edge of a cloud); the color temperature change rate refers to the amount of color temperature change of the luminous pixel unit 21 per unit time, reflecting how fast the color temperature of the luminous pixel unit 21 changes dynamically, and is reflected in the lighting effect as a corresponding color temperature gradient over time (e.g., the rate of color temperature decrease from orange-red to deep blue in the sunset); the brightness change rate refers to the amount of brightness change of the luminous pixel unit 21 per unit time, reflecting how fast the brightness of the luminous pixel unit 21 changes dynamically, and is reflected in the lighting effect as a corresponding brightness gradient over time (e.g., the rate of brightness increase from dim to bright in the dawn). Since the true color of natural light originates from its specific spectral power distribution, by controlling the spectral power distribution, the true color components of specific natural light can be reproduced more accurately. By controlling the color temperature change gradient and / or brightness change gradient, the natural gradation of light in space is simulated, enhancing the color realism and spatial layering of the lighting effect, making the simulation effect closer to real natural light. By controlling the rate of color temperature change and / or the rate of brightness change, the dynamic process of soft transition of light in natural scenes can be simulated in the time dimension, such as the passing of clouds or the process of sunset. This makes the generated scene no longer a rigid, static pattern, but a light and shadow performance full of dynamic details and realistic texture, further enhancing the sense of immersion.

[0052] Please combine Figure 4 and Figure 5Furthermore, when the light-emitting component 20 emits light corresponding to a preset lighting scene type, multiple independently controlled light-emitting pixel units 21 form a single optical feature partition 22; or, multiple independently controlled light-emitting pixel units 21 form at least two optical feature partitions 22, the color temperature change gradient of the light-emitting pixel units 21 within the same optical feature partition 22 is less than the color temperature change gradient of the light-emitting pixel units 21 between different optical feature partitions 22; the brightness change gradient of the light-emitting pixel units 21 within the same optical feature partition 22 is less than the brightness change gradient of the light-emitting pixel units 21 between different optical feature partitions 22.

[0053] Understandably, Figure 4 The diagram illustrates a scenario where multiple independently controlled light-emitting pixel units 21 form a single optical feature partition 22. The optical effects of each light-emitting pixel unit 21 within the single optical feature partition 22 are relatively similar. The formation of a single optical feature partition 22 by multiple independently controlled light-emitting pixel units 21 is applicable to lighting types with a large area of ​​uniform optical tone. Figure 5 The diagram illustrates a scenario where multiple independently controlled luminescent pixel units 21 form at least two optical feature partitions 22. By defining the optical feature partitions 22 and constraining the color temperature and brightness variation gradients within and between the optical feature partitions 22, the problem of rigidity in simple partition designs is solved. Smaller variation gradients can be set in areas requiring smooth transitions (such as the same area simulating the sky) to achieve a soft and uniform lighting effect, while larger variation gradients are allowed between different optical feature partitions 22 (such as the boundary between blue sky and white clouds) to form a clear light scene outline. This partitioning strategy can collaboratively achieve a clear macroscopic light scene structure division and a soft microscopic light transition on a single mirror illumination device 1, thereby efficiently and realistically constructing a detailed light scene.

[0054] For ease of understanding, Figure 5 For example, let's illustrate this. Figure 5The displayed lighting pattern is a blue sky and white clouds pattern. The first optical feature partition 221 is the core area of ​​the high-altitude blue sky, the second optical feature partition 222 is the transition area of ​​the low-altitude blue sky, and the third optical feature partition 223 is the area of ​​white clouds. The first emitting pixel unit 21a and the second emitting pixel unit 21b are located in the same second optical feature partition 222, while the second emitting pixel unit 21b and the third emitting pixel unit 21c are located in different second optical feature partitions 222 and third optical feature partitions 223. The direction from the first emitting pixel unit 21a to the second emitting pixel unit 21b is defined as the gradient direction. The color temperature change gradient of the second emitting pixel unit 21b obtained along the gradient direction based on the first emitting pixel unit 21a and the second emitting pixel unit 21b is less than the color temperature change gradient of the third emitting pixel unit 21c obtained along the gradient direction based on the second emitting pixel unit 21b and the third emitting pixel unit 21c. Similarly, the brightness change gradient of the second light-emitting pixel unit 21b obtained along the gradient direction based on the first light-emitting pixel unit 21a and the second light-emitting pixel unit 21b is less than the brightness change gradient of the third light-emitting pixel unit 21c obtained along the gradient direction based on the second light-emitting pixel unit 21b and the third light-emitting pixel unit 21c.

[0055] Please see Figure 4 Furthermore, the light-emitting pixel unit 21 includes a red LED 211, a green LED 212, a blue LED 213, and a white LED 214. The control component 30 achieves color temperature control of the light-emitting pixel unit 21 by adjusting the light emission ratio of the red LED 211, green LED 212, blue LED 213, and white LED 214, and achieves brightness control of the light-emitting pixel unit 21 by adjusting the driving current of the red LED 211, green LED 212, blue LED 213, and white LED 214.

[0056] Understandably, by employing multi-color LEDs, specifically RGBW (red (R), green (G), blue (B), and white (W)) combinations as light-emitting pixel units 21, and adjusting the light emission ratio and driving current, independent control of color temperature and brightness is achieved. This gives the mirror lighting device 1 a high degree of freedom in color expression and precise brightness control. The RGB three-primary-color principle can mix to produce extremely rich colors, while adding white LEDs 214 further improves the luminous efficiency and color performance in high color temperature areas, enabling the mirror lighting device 1 to cover a wide color temperature range and ensure excellent color consistency at all brightness levels. Furthermore, LED chips are relatively inexpensive, reducing manufacturing costs while ensuring lighting effects.

[0057] Optionally, as a modified implementation, the light-emitting pixel unit 21 includes red LED 211, green LED 212, and blue LED 213; as well as at least one of yellow LED, ice blue LED, pure white LED, and warm white LED, thereby greatly expanding the color expression and improving the color mixing efficiency, enabling more accurate and efficient reproduction of key colors commonly found in natural scenes but difficult to perfectly reproduce by traditional RGB systems. For example, yellow LEDs can directly produce saturated golden light, making the warm tones of sunsets purer and more vibrant, avoiding the color unevenness and energy loss that may occur when yellow is produced by mixing red LED 211 and green LED 212; ice blue LEDs can directly provide clear sky blue and lake blue, significantly improving the purity and brightness of the blue spectrum in traditional RGB systems when simulating high color temperature blue skies. White LED 214 can be further subdivided into three categories: warm white LEDs, pure white LEDs, and cool white LEDs. Adding warm white or neutral white LEDs not only provides a more efficient and stable light source base when high-brightness white light is needed, avoiding the color drift and brightness loss that may occur when mixing white with red LED211, green LED212, and blue LED213 in an RGB system, but also produces smoother and more continuous full-spectrum light by mixing its rich spectral components with other color LEDs. This improves the overall color saturation, brightness, and realism of the lighting simulation, making the final lighting effect closer to nature.

[0058] Optionally, the color temperature of the white LED214 is between 2700K and 7000K; the color temperature of the warm white LED is between 2700K and 3500K; the color temperature of the neutral white LED is between 4000K and 5000K; the dominant wavelength of the yellow LED is between 580nm and 620nm; and the dominant wavelength of the ice blue LED is between 450nm and 480nm.

[0059] Please combine Figure 1 and Figure 2 Furthermore, the mirror body 40 also includes a mirror surface 42, which is separated from the light-transmitting part 41.

[0060] Understandably, the partitioning ensures that the mirror imaging area and the light-transmitting illumination area do not interfere with each other, and their functions are clearly defined. The mirror surface 42 retains the imaging properties of the mirror body 40, ensuring a clear mirror effect when the user looks in the mirror, while the light-transmitting part 41 serves as an independent light output area, which can adapt to the adjustment needs of the light-emitting component 20 and present the color and brightness characteristics of the scene.

[0061] Please see Figure 6 Furthermore, a light-diffusing element 23 is provided on the outside of the light-emitting pixel unit 21, and the light from the light-emitting pixel unit 21 passes through the light-diffusing element 23 and the light-transmitting part 41 in sequence.

[0062] Understandably, by setting up the light homogenizer 23, the problem of uneven light from multiple independent light-emitting pixel units 21 is effectively solved. The light homogenizer 23 can scatter and mix the light emitted by each light-emitting pixel unit 21, eliminate the point light source characteristics of a single LED, avoid the graininess of the surface light source formed by multiple independent light-emitting pixel units 21, make the emitted light softer and more uniform, form a continuous and natural light scene, avoid the destruction of the realism of the light scene by discrete light sources, thereby improving the quality of the final emitted light and ensuring that the simulated light scene has a smooth and delicate visual effect.

[0063] Please combine Figure 1 and Figure 2 Furthermore, in the light-emitting component 20, the number of light-emitting pixel units 21 is greater than or equal to 10, and the light-emitting area of ​​a single light-emitting pixel unit 21 is less than or equal to 1 cm². 2 .

[0064] Understandably, by quantitatively limiting the number and individual area of ​​the luminescent pixel units 21, the lighting simulation achieves sufficiently high spatial resolution and detail. A number of luminescent pixel units 21 greater than or equal to 10 means that the lighting scene can be divided and controlled in a more detailed manner, and the luminescent area of ​​a single luminescent pixel unit 21 is less than or equal to 1 cm². 2 This means that the light output of each light-emitting pixel unit 21 is more concentrated, which can depict more delicate light and shadow details. The combination of the two enables the mirror lighting device 1 to create high-quality light and shadow patterns with clear boundaries and delicate transitions, avoiding the problem of rough and blurry light and shadow caused by the light-emitting pixel unit 21 having too large an area or too few units.

[0065] Please combine Figure 5 , Figure 7 and Figure 8Furthermore, when the light-emitting component 20 emits light of the first lighting type, multiple independently controlled light-emitting pixel units 21 form a first optical feature partition 221, a second optical feature partition 222, and a third optical feature partition 223. The color temperature of the first optical feature partition 221 is between 10000K and 15000K, and the brightness is between 270lm and 450lm; the color temperature of the second optical feature partition 222 is between 7800K and 10000K, and the brightness is between 140lm and 210lm; the color temperature of the third optical feature partition 223 is between 5000K and 6500K, and the brightness is between 150lm and 300lm. When the light-emitting component 20 emits light of the second lighting type, multiple independently controlled light-emitting pixel units 21 form a fourth optical feature partition 224, a fifth optical feature partition 225, and a sixth optical feature partition 226. 6. The color temperature of the fourth optical feature zone 224 is between 1800K and 2500K, and the brightness is between 120lm and 240lm; the color temperature of the fifth optical feature zone 225 is between 2500K and 3500K, and the brightness is between 180lm and 360lm; the color temperature of the sixth optical feature zone 226 is between 3500K and 4500K, and the brightness is between 50lm and 150lm; when the light-emitting component 20 emits light of the third light scene type, multiple independently controlled light-emitting pixel units 21 form the seventh optical feature zone 227 and the eighth optical feature zone 228. The color temperature of the seventh optical feature zone 227 is between 5000K and 6000K, and the brightness is between 75lm and 200lm; the color temperature of the eighth optical feature zone 228 is between 5500K and 7000K, and the brightness is between 60lm and 120lm.

[0066] Understandably, by specifically defining the color temperature and brightness parameter ranges of each optical feature zone under different lighting scene types, a direct and operable quantitative scheme is provided for achieving high-fidelity reproduction of several typical natural lighting scenes. The first lighting scene type is a blue sky and white clouds scene, with the first optical feature zone 221 being the core area of ​​the high-altitude blue sky, the second optical feature zone 222 being the transition area of ​​the low-altitude blue sky, and the third optical feature zone 223 being the white cloud area; the second lighting scene type is a sunset and evening glow scene, with the fourth optical feature zone 224 being the core area surrounding the sunset, the fifth optical feature zone 225 being the red-orange area of ​​the evening glow, and the sixth optical feature zone 226 being the afterglow transition area; the third lighting scene type is a lush green grassland scene, with the seventh optical feature zone 227 being the area of ​​green grass and leaves, and the eighth optical feature zone 228 being the highlight area of ​​flowers. These parameter ranges are based on specific settings of the physical optical characteristics of real lighting scenes, enabling the creation of specific atmospheric lighting scenes with a high degree of immersion. It should be noted that lm (lumen) is a physical unit describing luminous flux. In physics, it is defined as the total luminous flux emitted by one candle (cd, candela, a unit of luminous intensity, equivalent to the luminous intensity of an ordinary candle) over a solid angle (the angle represented by the cone corresponding to the spherical cap of a unit sphere with a radius of 1 meter, and the central angle of its corresponding midsection is approximately 65°).

[0067] Please see Figure 9 The second embodiment of the present invention provides a mirror lighting device 1a, which differs from the mirror lighting device 1 provided in the first embodiment of the present invention in that: the light-emitting pixel unit 21 includes a red LED 211, a green LED 212 and a blue LED 213, and the control component 30 achieves color temperature control of the light-emitting pixel unit 21 by adjusting the light emission ratio of the red LED 211, the green LED 212 and the blue LED 213, and achieves brightness control of the light-emitting pixel unit 21 by adjusting the driving current of the red LED 211, the green LED 212 and the blue LED 213.

[0068] Understandably, by using multi-color LEDs, namely RGB (red (R), green (G), blue (B)) combinations as light-emitting pixel units 21, the independent control of color temperature and brightness can be achieved by adjusting the light emission ratio and driving current; thus, the mirror lighting device 1a has a high degree of freedom in color expression and precise brightness control capability. The RGB three-primary-color principle can mix extremely rich colors, and the LED beads have a low cost, which can reduce manufacturing costs while ensuring the lighting effect.

[0069] Please see Figure 10The third embodiment of the present invention provides a mirror lighting device 1b, which differs from the mirror lighting device 1 provided in the first embodiment of the present invention in that: the mirror body 40 further includes a mirror surface 42, and the mirror surface 42 is provided with a semi-reflective and semi-transparent coating layer 46 to form a light-transmitting part 41. The semi-reflective and semi-transparent coating layer 46 reflects the external image while allowing the light emitted by the light-emitting component 20 to pass through.

[0070] Understandably, by using a semi-reflective coating layer 46, the front of the mirror body 40 can reflect ambient light, while the back remains transparent to allow light emitted by the light-emitting component 20 to pass through. This makes the mirror surface 42 also a light-transmitting part 41, expanding the illumination area of ​​the surface light source. This allows the background light to radiate through a larger area while the user is looking in the mirror, achieving a seamless integration of mirror imaging and ambient lighting, creating a more realistic and natural lighting environment, and further enhancing the user's sense of immersion.

[0071] Please combine Figure 1 , Figure 2 and Figure 11 The third embodiment of the present invention provides a method for adjusting the lighting type of a mirror lighting device 1. The mirror lighting device 1 includes a base 10, a light-emitting component 20, a control component 30, and a mirror body 40. A receiving space 50 is formed between the base 10 and the mirror body 40. The light-emitting component 20 is disposed within the receiving space 50. The control component 30 is electrically connected to the light-emitting component 20. The mirror body 40 is provided with a light-transmitting part 41. The light-emitting surface 24 and the light-transmitting part 41 of the light-emitting component 20 are arranged sequentially in a direction away from the base 10. The light-emitting component 20 includes a plurality of independently controlled light-emitting pixel units 21. The method for adjusting the lighting type of the mirror lighting device 1 includes the following steps: Step S1: Obtain the scene type adjustment command, which includes the target scene type information; Step S2: Based on the target lighting type information, the control component 30 retrieves the corresponding optical control parameter group from the preset parameter library; In step S3, the control component 30 adjusts the optical control parameters of each light-emitting pixel unit 21 according to the optical control parameter group. The light-emitting pixel unit 21 emits light that matches the target lighting type, and the light is emitted through the light-transmitting part 41.

[0072] It should be noted that the optical control parameter group includes the optical control parameters of each light-emitting pixel unit 21, and the control component may include a storage element, with a preset parameter library stored in the storage element for the control component to retrieve.

[0073] Understandably, the method for adjusting the lighting type of the mirror lighting device 1 has the same beneficial effects as the aforementioned mirror lighting device 1, and will not be repeated here.

[0074] Compared with the prior art, the mirror lighting device and the method for adjusting the lighting style of the mirror lighting device provided by the present invention have the following beneficial effects: 1. This invention provides a mirror lighting device, comprising a base, a light-emitting component, a control component, and a mirror body. A receiving space is formed between the base and the mirror body. The light-emitting component is disposed within the receiving space. The control component is electrically connected to the light-emitting component. The mirror body has a light-transmitting portion. The light-emitting surface and the light-transmitting portion of the light-emitting component are arranged sequentially away from the base. The light-emitting component includes multiple independently controllable light-emitting pixel units. The control component adjusts the optical control parameters of each light-emitting pixel unit, causing the light-emitting component to emit light corresponding to a preset lighting scene type. The light is emitted through the light-transmitting portion. By setting the light-emitting component to include multiple independently controllable light-emitting pixel units, with the light-emitting surface and the light-transmitting portion arranged sequentially away from the base, and the light-emitting pixel units disposed on the back side of the light-transmitting portion, the light from the light-emitting pixel units can pass through and be emitted from the back side of the light-transmitting portion. By using the control component to independently and differentially adjust the optical control parameters of each light-emitting pixel unit, the problem of traditional devices being unable to present natural and realistic lighting scenes through localized differential control of light is solved. By precisely controlling the optical characteristics such as light color and brightness at different positions of the light-transmitting part through each light-emitting pixel unit of the light-emitting component, different complex lighting scenes can be simulated in a refined manner, providing users with a highly realistic and immersive lighting experience, and meeting users' needs for refined ambient lighting scenes of high-quality mirror lighting devices.

[0075] 2. The optical control parameters in this embodiment of the invention include color temperature and brightness. In the light scene simulation of the mirror lighting device, color temperature and brightness are the core optical control parameters of the mirror lighting device. By independently controlling the color temperature and brightness of each light-emitting pixel unit, the mirror lighting device can simultaneously achieve precise shaping of local areas in both color atmosphere and light-dark contrast, simulating the layers and gradient effects of different complex light scenes, thereby enhancing the realism and three-dimensionality of the light scene reproduction.

[0076] 3. In this embodiment of the invention, at least one of the optical control parameters, such as spectral power distribution parameter, color temperature change gradient, brightness change gradient, color temperature change rate, and brightness change rate, is further introduced, expanding the dimensions of light control and increasing the precision of the lighting effect. Spectral power distribution (SPD) refers to the functional relationship between the spectral density of a light source and its wavelength, describing the power distribution of light in different wavelength bands and reflecting the spectral composition characteristics of light (such as the power peak of a specific band, the power ratio of each band, etc.). Color temperature change gradient refers to the change in color temperature of a preset neighborhood of luminescent pixel units in the spatial dimension, used to reflect the drastic change in color temperature of the luminescent pixel units, and presenting a corresponding color temperature gradient amplitude in the lighting effect (such as the color temperature gradient amplitude of the blue sky from low to high altitude). Brightness change gradient refers to the change in brightness of a preset neighborhood of luminescent pixel units in the spatial dimension, used to reflect the brightness of the luminescent pixel units. The degree of change is reflected in the lighting effect as a corresponding brightness gradient (e.g., the brightness gradient from the center to the edge of a cloud); the color temperature change rate refers to the amount of color temperature change of a luminous pixel unit per unit time, reflecting how fast the color temperature of the luminous pixel unit changes dynamically, and is reflected in the lighting effect as a corresponding color temperature gradient over time (e.g., the rate of color temperature decrease from orange-red to deep blue in the sunset); the brightness change rate refers to the amount of brightness change of a luminous pixel unit per unit time, reflecting how fast the brightness of the luminous pixel unit changes dynamically, and is reflected in the lighting effect as a corresponding brightness gradient over time (e.g., the rate of brightness increase from dim to bright at dawn). Since the true color of natural light originates from its specific spectral power distribution, by controlling the spectral power distribution, the true color components of specific natural light can be reproduced more accurately. By controlling the color temperature change gradient and / or brightness change gradient, the natural gradation of light in space is simulated, enhancing the color realism and spatial layering of the lighting effect, making the simulation effect closer to real natural light. By controlling the rate of color temperature change and / or the rate of brightness change, the dynamic process of soft transition of light in natural scenes can be simulated in the time dimension, such as the passing of clouds or the process of sunset. This makes the generated scene no longer a rigid, static pattern, but a light and shadow performance full of dynamic details and realistic texture, further enhancing the sense of immersion.

[0077] 4. In this embodiment of the invention, when the light-emitting component emits light corresponding to a preset lighting scene type, multiple independently controlled light-emitting pixel units form a single optical feature partition; or, multiple independently controlled light-emitting pixel units form at least two optical feature partitions. The color temperature change gradient of the light-emitting pixel units within the same optical feature partition is less than the color temperature change gradient of the light-emitting pixel units between different optical feature partitions; the brightness change gradient of the light-emitting pixel units within the same optical feature partition is less than the brightness change gradient of the light-emitting pixel units between different optical feature partitions. The optical effects of each light-emitting pixel unit within a single optical feature partition are relatively similar. The formation of a single optical feature partition by multiple independently controlled light-emitting pixel units is applicable to lighting scene types with a large area of ​​uniform optical tone. Multiple independently controlled luminescent pixel units form at least two optical feature zones. By defining the optical feature zones and constraining the color temperature and brightness variation gradients within and between the optical feature zones, the problem of rigidity in simple zone design is solved. Smaller variation gradients can be set in areas requiring smooth transitions (such as the same area simulating the sky) to achieve soft and uniform lighting effects, while larger variation gradients are allowed between different optical feature zones (such as the boundary between blue sky and white clouds) to form clear light and shadow contours. This zone strategy can collaboratively achieve clear macroscopic light and shadow structure division and soft microscopic light transitions on a single mirror illumination device, thereby efficiently and realistically constructing a detailed light and shadow image.

[0078] 5. In this embodiment of the invention, multi-color LEDs, namely red LEDs, green LEDs, and blue LEDs; or red LEDs, green LEDs, blue LEDs, and white LEDs; or a combination of red LEDs, green LEDs, and blue LEDs, and at least one of yellow LEDs, ice-blue LEDs, pure white LEDs, and warm white LEDs, are used as light-emitting pixel units. The light emission ratio and driving current are adjusted to achieve independent control of color temperature and brightness. This gives the mirror lighting device a high degree of freedom in color expression and precise brightness control. The RGB three-primary-color principle can mix to produce extremely rich colors, and adding white LEDs further improves the luminous efficiency and color performance in the high color temperature range, enabling the mirror lighting device to cover a wide color temperature range and ensuring excellent color consistency at all brightness levels. Adding at least one of yellow LEDs, ice-blue LEDs, pure white LEDs, and warm white LEDs makes the emitted colors more balanced and rich. Furthermore, LED chips are relatively inexpensive, reducing manufacturing costs while ensuring lighting effects.

[0079] 6. In this embodiment of the invention, the partitioning ensures that the mirror imaging area and the light-transmitting illumination area do not interfere with each other, and their functions are clearly defined. The mirror surface retains the imaging properties of the mirror body, ensuring a clear mirror effect when the user looks in the mirror, while the light-transmitting part serves as an independent light output area, adaptable to the control requirements of the light-emitting components, presenting the color and brightness characteristics of the scene. Furthermore, the use of a semi-reflective, semi-transparent coating layer allows the mirror surface to also be a light-transmitting part, expanding the illumination area of ​​the surface light source. This allows background light to radiate through a larger area while the user looks in the mirror, achieving a seamless integration of mirror imaging and ambient lighting, creating a more realistic and natural lighting environment, and further enhancing the user's immersive experience.

[0080] 7. In this embodiment of the invention, by setting a light-diffusing element, the problem of uneven light distribution among multiple independent light-emitting pixel units is effectively solved. The light-diffusing element can scatter and mix the light emitted by each light-emitting pixel unit, eliminate the point light source characteristics of a single LED, avoid the graininess of the surface light source formed by multiple independent light-emitting pixel units, make the emitted light softer and more uniform, form a continuous and natural light scene, avoid the destruction of the realism of the light scene by discrete light sources, thereby improving the quality of the final emitted light and ensuring that the simulated light scene has a smooth and delicate visual effect.

[0081] 8. In this embodiment of the invention, by quantitatively limiting the number and individual area of ​​the light-emitting pixel units, the spatial resolution and fineness of the light scene simulation are ensured to be sufficiently high. A number of light-emitting pixel units greater than or equal to 10 means that the light scene can be divided and controlled in a more detailed manner. A light-emitting area of ​​a single light-emitting pixel unit less than or equal to 1 cm2 means that the light output of each light-emitting pixel unit is more concentrated, which can depict more fine light and shadow details. The combination of the two enables the mirror lighting device to create high-quality light scene patterns with clear boundaries and delicate transitions, avoiding the problem of rough and blurry light scenes caused by excessively large or insufficient light-emitting areas of the light-emitting pixel units.

[0082] 9. In this embodiment of the invention, by specifically defining the color temperature and brightness parameter ranges of each optical feature zone under different lighting scene types, a direct and operable quantitative scheme is provided for achieving high-fidelity reproduction of several typical natural lighting scenes. The first lighting scene type is a blue sky and white clouds scene, with the first optical feature zone being the core area of ​​the high-altitude blue sky, the second optical feature zone being the transition area of ​​the low-altitude blue sky, and the third optical feature zone being the white cloud area; the second lighting scene type is a sunset and evening glow scene, with the fourth optical feature zone being the core area surrounding the sunset, the fifth optical feature zone being the red-orange area of ​​the evening glow, and the sixth optical feature zone being the afterglow transition area; the third lighting scene type is a lush green grassland scene, with the seventh optical feature zone being the grass and green leaf area, and the eighth optical feature zone being the flower highlight area. These parameter ranges are based on specific settings of the physical optical characteristics of real lighting scenes, enabling the creation of specific atmospheric lighting scenes with a high degree of immersion.

[0083] 10. The present invention also provides a method for adjusting the lighting type of a mirror lighting device. The method for adjusting the lighting type of a mirror lighting device has the same beneficial effects as the above-mentioned mirror lighting device, and will not be described again here.

[0084] The foregoing has provided a detailed description of a mirror lighting device and a method for adjusting the lighting style of the mirror lighting device according to embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention. Any modifications, equivalent substitutions, and improvements made within the principles of the present invention should be included within the protection scope of the present invention.
