Detailed Implementation

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0018] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0019] The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] Please refer to Figures 1 to 3 This application discloses a lighting fixture 100, which may include a housing 110, a first light-emitting part 120, a second light-emitting part 130, and a light-transmitting plate 140. The housing 110 serves as the supporting foundation for the lighting fixture 100, used to fix and install the various functional components. The housing 110 may be made of materials such as aluminum alloy or engineering plastics. The housing 110 has a lamp cavity 111 inside, which provides installation space for the first light-emitting part 120 and the second light-emitting part 130. The first light-emitting part 120 and the second light-emitting part 130 can be positioned and installed in the lamp cavity 111 by means of bolt connection, snap-fit, adhesive bonding, etc. The housing 110 also has a light outlet 112, which is a channel for light to escape and communicates with the lamp cavity 111. The light-transmitting plate 140 can be set at the light outlet 112 of the housing 110 by means of bonding, snap-fitting, etc. The light-transmitting plate 140 has the functions of light transmission and carrying the holographic pattern layer. The material of the light-transmitting plate 140 can be glass, acrylic, etc. with high light transmittance to ensure that the light transmission loss is small, while having a certain structural strength to carry the holographic pattern layer.

[0021] The first light-emitting unit 120 is the core output component for the sky background light effect. The first light-emitting unit 120 can be an incandescent lamp, a halogen lamp, an LED (Light Emitting Diode), etc. The first light-emitting unit 120 is arranged opposite to the light-transmitting plate 140 to ensure that the light emitted by the first light-emitting unit 120 can be accurately directed to the light-transmitting plate 140. After the light is emitted through the light-transmitting plate 140, it can form a sky background with uniform coverage.

[0022] The light-transmitting plate 140 is provided with a holographic pattern layer, which is a functional pattern layer prepared using holographic imaging technology and is the core structure for realizing the simulated sunlight effect 101. The light emitted by the second light-emitting part 130 can be directed towards the holographic pattern layer. By utilizing the optical coordination between the light emitted by the second light-emitting part 130 and the holographic pattern layer, the planar light and shadow can be transformed into a three-dimensional light effect with a sense of depth, thereby forming a simulated sunlight effect 101 with visual depth at the light outlet 112 of the housing 110; at the same time, the holographic pattern layer will not affect the presentation of the sky background light effect of the first light-emitting part 120.

[0023] It should be noted that the imaging of the holographic pattern layer is based on the optical principle of "interference recording and diffraction regeneration." This holographic pattern layer can be pre-fabricated using holographic technology. The specific process is as follows: First, the pattern of the target solar light effect (such as the sun's outline, depth of field, etc.) is determined. Laser interference technology is used to record the light wave information. A laser beam is split into two beams: one is the "object beam," which illuminates the target object simulating the sun's shadow, carrying the object's outline, brightness, depth of field, and other light and shadow information to the surface of the light-transmitting plate 140; the other is the "reference beam," which directly illuminates the surface of the light-transmitting plate 140. The object beam and the reference beam interfere on the surface of the light-transmitting plate 140, forming alternating bright and dark interference fringes. These fringes are the light wave information carriers of the target sun's shadow. Then, the interference fringes are fixed on the surface of the light-transmitting plate 140 using a photosensitive material, forming the aforementioned holographic pattern layer.

[0024] When the lighting fixture 100 is running, the light emitted by the second light-emitting part 130 is directed towards the holographic pattern layer. The specific imaging logic is as follows: When the wavelength, propagation direction, and other parameters of the light emitted by the second light-emitting part 130 match the reference light pre-fabricated in the holographic pattern layer, diffraction occurs when the light emitted by the second light-emitting part 130 illuminates the interference fringes of the holographic pattern layer. The interference fringes are equivalent to a "diffraction grating," which can reproduce the decomposition of light into multiple beams of diffracted light carrying target light and shadow information. The propagation direction of the diffracted light is consistent with the propagation direction of the object light pre-fabricated in the holographic pattern layer, thus carrying the three-dimensional information (outline, brightness, and distance) of the target sunlight. When the human eye observes the light outlet 112, after receiving the diffracted light, a simulated sunlight effect 101 with visual depth is formed, as if the sun is located at a certain distance behind the lighting fixture 100, presenting a three-dimensional and realistic effect.

[0025] In addition to forming a simulated sunlight effect 101 with visual depth, the light emitted by the second light-emitting part 130 is also emitted through the light-transmitting plate 140 and directed towards the target area outside the lighting fixture 100 (such as the wall, furniture surface, etc.), thereby forming a light spot 102 that simulates sunlight transmission in the target area, ultimately achieving an immersive overlay effect of "sky background + three-dimensional sunlight effect + sunlight spot".

[0026] As described above, the lighting fixture 100 disclosed in this application improves upon related technologies. The light emitted by the first light-emitting part 120 can pass through the light-transmitting plate 140 and form a sky background light effect; the light emitted by the second light-emitting part 130 can be directed towards the holographic pattern layer on the light-transmitting plate 140. Utilizing the holographic imaging principle of the holographic pattern layer, a simulated sunlight effect 101 with visual depth can be formed at the light outlet 112; furthermore, some of the light emitted by the second light-emitting part 130 can also be emitted through the light-transmitting plate 140, thereby forming a simulated sunlight transmission spot 102 in the target area outside the lighting fixture 100. Using the above solution, the lighting fixture 100 can present rich light effects with good layering, thus realistically simulating the effect of complete natural sky lighting, thereby enhancing the user experience of the lighting fixture 100.

[0027] The light emitted by the second light-emitting part 130 can be directly directed onto the light-transmitting plate 140. Considering that the direct-light installation method may cause glare, in this embodiment, the lighting fixture 100 may also include a reflector 150. The reflector 150 may be made of a metal plate (such as an aluminum plate) with a polished surface or an optical plate with a high-reflection coating to ensure high light reflection efficiency and low loss. It is positioned and installed in the lamp cavity 111, and can be fixed by means of clips, screws, etc. to ensure installation stability.

[0028] The relative arrangement of the reflector 150 and the second light-emitting part 130 ensures that the light emitted by the second light-emitting part 130 can be directed to the reflective surface of the reflector 150 to the maximum extent, thus avoiding light waste. The preset angle between the reflective surface and the plane of the light-transmitting plate 140 is the key to achieving accurate reflection of light to the light-transmitting plate 140 (especially the holographic pattern layer), and can be adapted and adjusted according to the overall size of the lighting fixture 100 and the installation position of the second light-emitting part 130.

[0029] By reflecting light through the reflector 150, the installation position of the second light-emitting part 130 can be flexibly adjusted (without having to face the light-transmitting plate 140 directly), optimizing the internal spatial layout of the lamp cavity 111. At the same time, it ensures that the light emitted by the second light-emitting part 130 can be accurately directed onto the light-transmitting plate 140 (holographic pattern layer), improving the presentation accuracy of the simulated sunlight effect 101 and avoiding light effect distortion caused by light deflection.

[0030] In the above scheme, the preset angle between the reflective surface and the plane of the light-transmitting plate 140 can be between 30° and 60°, specifically 30°, 40°, 50°, 60°, etc. This angle range is the optimal range determined through multiple optical simulations and physical tests. When the preset angle is less than 30°, the reflected light is too flat, making it difficult to form an effective optical combination with the holographic pattern layer, resulting in insufficient visual depth of field and weakened three-dimensionality of the solar effect. When the angle is greater than 60°, the angle of the reflected light is too large, easily deviating from the effective imaging area of ​​the holographic pattern layer, resulting in blurred outline and uneven brightness of the simulated solar effect 101. By adopting the aforementioned angle range of 30° to 60°, it is possible to ensure that the reflected light accurately covers the holographic pattern layer, while maximizing the depth of field and three-dimensionality of the simulated solar effect 101, balancing the accuracy of the light effect and the visual experience.

[0031] In one optional embodiment of this application, the lighting fixture 100 may further include a diffuser plate 160, which is positioned within the lamp cavity 111 and located between the first light-emitting part 120 and the light-transmitting plate 140. The diffuser plate 160 may be a high-transmittance optical material with microstructures (such as frosted texture or diffused particles). The diffuser plate 160 is positioned and installed between the first light-emitting part 120 and the light-transmitting plate 140, and it can be fixed by means of slots, brackets, etc., to ensure flat installation and avoid uneven light diffusion caused by tilting.

[0032] The light emitted by the first light-emitting part 120 is dispersed into uniform scattered light after passing through the diffuser plate 160, avoiding the appearance of local bright spots and dark areas that would affect the light effect. This can improve the softness and uniformity of the sky background light effect, making the sky background more transparent and closer to the natural state, while avoiding strong light directing from interfering with the imaging effect of the holographic pattern layer.

[0033] In this embodiment, the first light-emitting part 120 may include a first substrate 121 and a plurality of RGB light-emitting units 122 disposed on the first substrate 121. The light emitted by the plurality of RGB light-emitting units 122 is mixed with each other to form a sky background light effect.

[0034] Specifically, the first substrate 121 can be a PCB (Printed Circuit Board), FPC (Flexible Printed Circuit), etc. The size of the first substrate 121 is adapted to the lamp cavity 111 to support the RGB light-emitting unit 122 and provide a circuit connection channel. Its surface can be provided with heat dissipation textures to improve heat dissipation performance and ensure the stable operation of the RGB light-emitting unit 122. The RGB light-emitting unit 122 is a light-emitting element integrating red, green, and blue primary color light-emitting chips. Multiple RGB light-emitting units 122 can be evenly distributed on the surface of the first substrate 121 facing the light-transmitting plate 140. The RGB light-emitting units 122 can be fixed to the first substrate 121 by soldering. Multiple RGB light-emitting units 122 work together, and different colors of light can be mixed by adjusting the brightness ratio of the three primary colors.

[0035] By mixing the light from multiple RGB light-emitting units 122, various light colors suitable for sky scenes, such as blue (sunny day), gray-white (cloudy day), and orange (sunrise / sunset), can be flexibly output. At the same time, the RGB light-emitting units 122 can also be used to simulate light effects such as clouds and sunset, realizing diversified switching of sky background light effects to meet the atmosphere creation needs of different scenes. Compared with single-color light-emitting components, the solution in this embodiment has stronger adaptability and richer light effects.

[0036] In conjunction with the above, the second light-emitting part 130 can be a laser light source. The second light-emitting part 130 can include a second substrate and a plurality of RGB laser units disposed on the second substrate. The light emitted by the plurality of RGB laser units is mixed with each other to form a simulated sunlight effect 101 and a simulated sunlight transmission light spot 102.

[0037] Specifically, compared to ordinary LED light sources, laser light sources have the characteristics of high light concentration, strong directionality, and high brightness, which can meet the requirements of simulating the penetrating sense of sunlight effect 101 and the clear outline of the light spot. It is the core light source type for realizing the sunlight effect with depth of field and sunlight spot.

[0038] Similar to the first substrate 121, the second substrate can also be a PCB (Printed Circuit Board), FPC (Flexible Printed Circuit), etc. The size of the second substrate is adapted to the mounting area of ​​the second light-emitting part 130. The second substrate is used to support the RGB laser unit and provide circuit connections, ensuring timely heat dissipation during the operation of the RGB laser unit. The RGB laser unit uses laser as the light-emitting carrier and integrates red, green, and blue laser chips. Multiple RGB laser units can be evenly distributed on the second substrate, and the RGB laser units can be fixed to the second substrate by soldering. The simulated sunlight formed by the mixing of multiple RGB laser units has sufficient concentration and directionality, which can form an effective optical combination with the holographic pattern layer to present a simulated sunlight effect 101 with depth of field. On the other hand, after the high-intensity laser light penetrates the light-transmitting plate 140, it can form a light spot with clear outline and uniform brightness in the target area outside the lighting fixture 100, replicating the transmission effect of natural sunlight as much as possible.

[0039] In this embodiment, the second light-emitting part 130 may further include a shaping lens 131, which is disposed on the light-emitting side of the plurality of RGB laser units. The shaping lens 131 shapes the light emitted by the plurality of RGB laser units into a light spot of a preset shape.

[0040] Specifically, the shaping lens 131 can be made of optical glass or acrylic material. The shaping lens 131 can have a curved structure. The shaping lens 131 can be fixed to the light-emitting side of the RGB laser unit by adhesive or clips to ensure precise alignment with the RGB laser unit and avoid light deviation.

[0041] The shaping lens 131 can be optically designed according to the shape of the simulated sunlight transmission spot 102 as required, so that the shaping lens 131 can converge and shape the scattered light emitted by the RGB laser unit to form a light spot of a preset shape, such as an ellipse or a rectangle.

[0042] By shaping the light through the shaping lens 131, the light output from the second light-emitting part 130 can form a light spot with a clear outline and a standard shape. On the one hand, this can improve the regularity of the simulated sunlight effect 101 (such as a circular sun outline), and on the other hand, it can ensure that the shape of the sunlight spot in the external target area conforms to the natural sunlight presentation, further enhancing the realism of the light and shadow simulation.

[0043] In this embodiment, the holographic pattern layer can be disposed on the surface of the light-transmitting plate 140 away from the first light-emitting part 120 (outer surface), or it can be disposed on the surface of the light-transmitting plate 140 close to the first light-emitting part 120 (inner surface). Taking the inner surface of the light-transmitting plate 140 as an example, disposing of the holographic pattern layer on the inner surface of the light-transmitting plate 140 avoids its direct exposure to the external environment, reduces damage to the holographic pattern layer caused by dust adhesion and external scratches, extends its service life, and ensures long-term stable imaging effects. Furthermore, the light emitted by the second light-emitting part 130 can be reflected and directly illuminate the inner surface of the light-transmitting plate 140, thereby precisely acting on the holographic pattern layer without the need for additional adjustment of the light path and optimizing the precision of the optical structure. In one optional embodiment of this application, the lighting fixture 100 may further include a light-transmitting partition 170 and a decorative frame 180. The light-transmitting partition 170 may be made of high-transmittance quartz glass or acrylic sheet, and may be positioned and installed within the lamp cavity 111 by means of clips, screws, or other components. The light-transmitting partition 170 may divide the lamp cavity 111 into at least a first sub-cavity 1111 and a second sub-cavity 1112. The decorative frame 180 may be made of materials such as aluminum alloy or plastic, and its surface may be treated by processes such as anodizing or spraying. The decorative frame 180 is arranged around the light outlet 112 and may be fixed to the housing 110 by means of clips or adhesives.

[0044] The first light-emitting part 120 can be disposed within the first sub-cavity 1111, which is opposite to the light-transmitting plate 140, and can be adapted to the sky background light effect output requirements of the first light-emitting part 120. A decorative frame 180 is disposed around the light outlet 112, and the second sub-cavity 1112 is opposite to the decorative frame 180. The second light-emitting part 130 can be disposed within the second sub-cavity 1112. The decorative frame 180 can cover the internal structure of the second sub-cavity 1112 (the second light-emitting part 130), thereby improving the appearance of the lighting fixture 100. The light emitted by the second light-emitting part 130 can be projected onto the light-transmitting plate 140 through the light-transmitting partition 170. The separation function of the light-transmitting partition 170 can prevent the diffused light of the first light-emitting part 120 from interfering with the laser of the second light-emitting part 130, ensuring that the two light effects are presented independently and accurately; at the same time, the light-transmitting characteristics of the light-transmitting partition 170 can ensure that the light of the second light-emitting part 130 passes through smoothly and shines on the light-transmitting plate 140 without affecting the normal presentation of the light effect.

[0045] In one optional embodiment of this application, the lighting fixture 100 may further include a control module, which is electrically connected to the first light-emitting part 120 and the second light-emitting part 130, respectively. The control module is a core component integrating a microcontroller, a driver chip, a signal receiving unit, etc. The control module can be installed in the side wall or bottom of the lamp cavity 111, etc. The control module can establish electrical connections with the first light-emitting part 120 and the second light-emitting part 130 through wires to ensure stable signal transmission.

[0046] The control module can control the on / off state and brightness adjustment of the first light-emitting unit 120 and the second light-emitting unit 130 separately, such as individually activating the sky background light effect or the sunlight effect. Simultaneously, the control module can also achieve coordinated adjustment between the first light-emitting unit 120 and the second light-emitting unit 130; for example, in sunrise mode, the sky background gradually changes from orange to blue, and the sunlight effect gradually increases in intensity. The control module also supports external control signals such as remote control, APP, and voice, improving ease of use and adapting to the operational needs of different scenarios.

[0047] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0048] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
