Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to a blue sky module and a blue sky lamp. Background Technology
[0002] Among existing lighting devices, the Skylight (also known as the Sky lamp or Blue Sky lamp) is a lighting device that can simulate the visual effect of the sky. It can provide a skylight-like lighting effect for indoor spaces that cannot be illuminated by sunlight, providing users with a comfortable visual experience.
[0003] Most existing sky lights use a Rayleigh diffuser to illuminate the sky at an angle, thus simulating the visual effect of the sky. However, the blue sky effect presented by this method is rather hazy and it is difficult to achieve a clear, clear sky effect. It is necessary to use reflective materials (such as reflectors) to improve the blue sky effect. However, adding such materials will result in a larger overall thickness and volume of the sky light, which is not conducive to the installation of the light fixture. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a blue sky module and a blue sky light, enabling the light fixture to present a deep sky effect while also ensuring ease of installation.
[0005] To solve the above-mentioned technical problems, this utility model provides a blue sky module, including: a mounting frame with a recessed groove inside;
[0006] A light source assembly is disposed on the inner side wall of the settling tank;
[0007] A light-scattering guide plate is disposed in the sink, with the light-incident surface of the light-scattering guide plate located on the side, the light-emitting surface of the light source group facing the light-incident surface, and the reflective surface of the light-scattering guide plate facing the inner bottom wall of the sink. Furthermore, a semi-transparent and semi-reflective coating is applied to the reflective surface of the light-scattering guide plate and / or the inner bottom wall of the sink.
[0008] As an improvement to the above scheme, the semi-transparent and semi-reflective coating is a single-sided semi-transparent coating, and the scattering light guide plate is a Rayleigh scattering light guide plate.
[0009] As an improvement to the above solution, the single-sided semi-permeable coating is made of metal material, or the single-sided semi-permeable coating is a multilayer dielectric film.
[0010] As an improvement to the above solution, a protective layer is provided on the side of the semi-transparent and semi-reflective plating layer facing the bottom of the sink.
[0011] As an improvement to the above solution, the light source group includes a first light source and a second light source, which are symmetrically arranged on both sides of the scattering light guide plate.
[0012] As an improvement to the above solution, a preset distance is formed between the emitting surface of the first light source and the side surface of the scattering light guide plate, the preset distance being 1mm-3mm; the preset distance is also formed between the emitting surface of the second light source and the incident surface of the scattering light guide plate.
[0013] As an improvement to the above solution, the first light source is a light strip extending along a preset direction; or the first light source is a plurality of lamp beads, and the plurality of lamp beads are arranged at intervals along a preset direction, the preset direction being the length direction of the sink.
[0014] The arrangement of the second light source is the same as that of the first light source.
[0015] As an improvement to the above solution, the color temperature range of the light strip or the light bead is 5000K-12000K.
[0016] As an improvement to the above solution, the side wall of the mounting frame is provided with a plurality of bendable limiting buckles at intervals, the bending direction of the limiting buckles being towards the sink or away from the sink.
[0017] Accordingly, this utility model also provides a blue sky lamp, including a housing and a blue sky module as described in any one of the above, wherein the blue sky module is disposed inside the housing.
[0018] Implementing this utility model has the following beneficial effects:
[0019] In this embodiment, the light-scattering guide plate can scatter and refract the light entering from the light source to present a blue sky effect on the light-emitting surface of the light-scattering guide plate.
[0020] By applying a semi-transparent, semi-reflective coating to the inner bottom wall of the mounting frame, and using the semi-transparent, semi-reflective coating in conjunction with the scattering light guide plate, the refracted light is scattered and refracted in multiple stages between the semi-transparent, semi-reflective coating and the scattering light guide plate, thus achieving a deep sky effect with superimposed blue sky ambient light on the light-emitting surface of the lamp. Furthermore, there is no need to place reflective panels inside the mounting frame, reducing the number of panels used in the blue sky module and effectively reducing the overall thickness of the blue sky module. This allows the lamp to achieve a deep sky effect while also ensuring ease of installation. Attached Figure Description

[0025] 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.
[0026] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the Blue Sky module includes a mounting frame 1, a light source group 2, and a light-scattering guide plate 3. The mounting frame 1 has a recessed groove 11 inside, and the light source group 2 is located on the inner side wall of the recessed groove 11. The light-scattering guide plate 3 is located in the recessed groove 11, with its light-incident surface on the side, its light-emitting surface facing the light-incident surface, and its reflective surface facing the inner bottom wall of the recessed groove 11. Furthermore, the reflective surface of the light-scattering guide plate 3 and / or the inner bottom wall of the recessed groove 11 are coated with a semi-transparent, semi-reflective coating 4.
[0027] In this embodiment, the light scattering plate 3 can scatter and refract the light from the light source to present a blue sky effect on the light-emitting surface of the light scattering plate 3.
[0028] By applying a semi-transparent and semi-reflective coating 4 to the inner bottom wall of the mounting frame 1, and using the semi-transparent and semi-reflective coating 4 in conjunction with the scattering light guide plate 3, the refracted light is scattered and refracted in multiple segments between the semi-transparent and semi-reflective coating 4 and the scattering light guide plate 3, thus achieving a deep sky effect with superimposed blue sky ambient light on the light-emitting surface of the lamp. Furthermore, there is no need to place reflective panels inside the mounting frame 1, reducing the number of panels used in the blue sky module and effectively reducing the overall thickness of the blue sky module. This allows the lamp to present a deep sky effect while also ensuring ease of installation.
[0029] For example, the related technology's blue sky light uses a semi-transparent, semi-reflective plate arranged between the scattering light guide plate 3 and the mounting frame 1 to create a deep sky effect by combining the semi-transparent, semi-reflective plate and the scattering light guide plate 3. In this case, the overall thickness of the blue sky module is 8mm-15mm, and the blue color ratio of the light-emitting surface of the blue sky module is 51.5%.
[0030] In this embodiment, a semi-transparent, semi-reflective coating 4 is applied to the reflective surface of the light-guiding plate 3. This semi-transparent, semi-reflective coating 4 replaces the semi-transparent, semi-reflective plate and works in conjunction with the light-guiding plate 3, achieving the same deep sky effect with superimposed ambient light. The blue light ratio of the light-emitting surface of the blue sky module can also reach 51.5%. Furthermore, with the same thickness of the light-guiding plate 3 and the mounting frame 1, the overall thickness of the blue sky module is 5mm-7mm, allowing the blue sky module to balance a deep sky effect with ease of installation.
[0031] It should also be noted that in other embodiments, the semi-transparent and semi-reflective plating layer 4 can also be applied to the inner bottom wall of the settling tank 11, and the position can be arranged according to actual needs.
[0032] In some optional embodiments, the semi-transparent and semi-reflective coating 4 is a single-sided semi-transparent coating, and the scattering light guide plate 3 is a Rayleigh scattering light guide plate 3. The single-sided semi-transparent coating can adjust the transmittance and reflectance of light to achieve a specific transmission and reflection ratio (such as 50% transmission and 50% reflection), while ensuring that the light is evenly distributed inside the scattering light guide plate 3 and evenly emitted from the light-emitting surface of the scattering light guide plate 3, thereby optimizing the light emission uniformity of the blue sky module.
[0033] Preferably, the single-sided semi-transparent coating can be applied to the Rayleigh scattering light guide plate 3 using vacuum coating technology (such as vacuum evaporation or magnetron sputtering) to ensure the uniformity and adhesion of the film layer.
[0034] Furthermore, the single-sided semi-transparent coating is made of metal material to form a thin metal film on the reflective surface of the light-scattering guide plate 3 and / or the inner bottom wall of the sink 11. The thickness of this film is easily adjustable, allowing for adjustment of the transmittance and reflectance of the semi-transparent coating, thus further ensuring the light output effect. Alternatively, the single-sided semi-transparent coating can be a multilayer dielectric film, which similarly allows for selective transmission or reflection of light by adjusting the optical thickness of the dielectric film, ensuring the light output effect.
[0035] Furthermore, such as Figure 2 As shown, a protective layer 41 is provided on the side of the semi-transparent and semi-reflective plating layer 4 facing the bottom surface of the sink 11. The protective layer 41 is preferably a protective back paint to prevent the semi-transparent and semi-reflective plating layer 4 from being physically damaged and falling off due to factors such as scratching, friction or mechanical impact.
[0036] In some alternative embodiments, such as Figure 1 As shown, the light source group 2 includes a first light source 21 and a second light source 22. The first light source 21 and the second light source 22 are symmetrically arranged on both sides of the scattering light guide plate 3 so as to symmetrically illuminate both sides of the scattering light guide plate 3 by the first light source 21 and the second light source 22, ensuring the uniformity of light on both sides of the scattering light guide plate 3, avoiding the appearance of areas with obvious light and dark distribution inside the scattering light guide plate 3, thereby improving the light output effect of the blue sky module.
[0037] In this system, a preset distance is formed between the emitting surface of the first light source 21 and the incident surface of the scattering light guide plate 3. The preset distance is 1mm-3mm, preferably 1mm. The second light source 22 and the incident surface of the scattering light guide plate 3 are also formed with a preset distance to ensure that the light from the first light source 21 and the second light source 22 can be uniformly irradiated into the interior of the scattering light guide plate 3, avoiding light efficiency loss and improving the light utilization efficiency of the scattering light guide plate 3. At the same time, when the first light source 21 and the second light source 22 are heated and expanded due to light emission, the scattering light guide plate 3 will not squeeze the first light source 21 and the second light source 22, ensuring the working safety of the first light source 21 and the second light source 22.
[0038] Specifically, such as Figure 3 and Figure 4 As shown, the first light source 21 is a light strip 211 extending along a preset direction; or the first light source 21 is multiple LED beads 212, and the multiple LED beads 212 are arranged at intervals along a preset direction, which is the length direction of the recessed groove 11; the arrangement of the second light source 22 is the same as that of the first light source 21. By using the arrangement of the light strip 211 or multiple LED beads 212 extending along the length direction of the recessed groove 11, the light from the first light source 21 and the second light source 22 can be evenly irradiated onto the light-emitting surface of the scattering light guide plate 3, thereby further ensuring the uniformity of light inside the scattering light guide plate 3, further avoiding areas with obvious light and dark distribution in the scattering light guide plate 3, and further improving the light emission effect of the blue sky module.
[0039] More specifically, the color temperature range of the light strip 211 or the light bead 212 is 5000K-12000K, with the preferred color temperature being 7500K, in order to improve the blue light ratio of the light and further ensure that after the light shines on the light guide plate 3, the light-emitting surface of the light guide plate 3 can present a blue sky ambient light effect with a better blue light ratio.
[0040] In some alternative embodiments, such as Figures 1 to 4 As shown, multiple bendable retaining buckles 12 are arranged at intervals on the side walls of the mounting frame 1. The bending direction of the retaining buckles 12 is towards or away from the recess 11. Therefore, when installing the light guide plate 3, the retaining buckles 12 can be bent away from the recess 11 to place the light guide plate 3 into the recess 11, improving the assembly convenience of the light guide plate 3; subsequently, the retaining buckles 12 can be bent towards the recess 11 to limit the light guide plate 3 in the recess 11, ensuring the assembly stability of the light guide plate 3.
[0041] Accordingly, this utility model also provides a sky light, which includes a housing and a blue sky module as described in any of the above embodiments, the blue sky module being disposed inside the housing. The sky light possesses all the beneficial effects of the aforementioned blue sky module, and it also combines the characteristics of a deep sky effect and thinness, making it convenient for installation and maintenance, and meeting the user's needs for low-rise buildings.
[0042] 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 invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
