Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a layered, gradient-transparent lampshade. Background Technology

[0002] Lampshades, as accessories for both lighting and decoration in home and commercial spaces, are widely used in interior design, exhibitions, and atmosphere creation. Through specific materials, structures, or pattern designs, they soften, diffuse, or shape light sources, achieving unique visual effects. Common artistic lampshades are often made of single or multiple layers of translucent materials, with some products enhancing their artistic expression through variations in color, texture, or openwork patterns.

[0003] However, existing lampshades often suffer from uneven light transmittance or abrupt color distribution, leading to uneven light scattering or excessively high local brightness, which negatively impacts overall visual softness and artistic expression. Therefore, it is necessary to develop a newer design technology to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a layered gradient light-transmitting lampshade to solve the problems in the above-mentioned background technology, such as the difficulty in achieving light transmittance or the fact that the color distribution of existing lampshades is often uniform or abruptly designed, which may lead to uneven light scattering or excessive local brightness, affecting the overall visual softness and artistic expression.

[0005] This utility model provides the following technical solution: a layered gradient light-transmitting lampshade, comprising an outer cover, a middle optical modulation layer group, an inner diffuser, and a support frame. The support frame is disposed within the outer cover, the inner diffuser is connected to the support frame, the middle optical modulation layer group is disposed between the outer cover and the inner diffuser, and the middle optical modulation layer group is fixedly connected to the support frame.

[0006] Preferably, the intermediate optical modulation layer group includes an inner light-transmitting layer, a middle light-transmitting layer, and an outer light-transmitting layer. The inner light-transmitting layer, the middle light-transmitting layer, and the outer light-transmitting layer are fixedly connected to the supporting frame. The inner light-transmitting layer, the middle light-transmitting layer, and the outer light-transmitting layer are all coated with an ink layer.

[0007] Preferably, the ink layer of the inner light-transmitting layer has a coverage rate of 20%, the ink layer of the middle light-transmitting layer has a coverage rate of 50%, and the ink layer of the outer light-transmitting layer has a coverage rate of 80%.

[0008] Preferably, the support frame includes an upper fixed plate, a lower fixed plate, and a connecting rod, wherein the upper fixed plate is fixedly connected to the lower fixed plate via the connecting rod or is integrally formed.

[0009] Preferably, the upper fixing plate and the lower fixing plate are provided with slots for fixing the inner light-transmitting layer, the middle light-transmitting layer and the outer light-transmitting layer, and the inner light-transmitting layer, the middle light-transmitting layer and the outer light-transmitting layer are connected to the upper fixing plate and the lower fixing plate through the slots.

[0010] Preferably, a conical structure is provided on the inner diffusion shroud, and the conical structure and the inner diffusion shroud are fixedly connected or integrally formed.

[0011] Preferably, sealing rings are provided at both ends of the outer light-transmitting layer, one side of the sealing ring is connected to the outer light-transmitting layer, and the other side of the sealing ring is connected to the outer cover. The outer light-transmitting layer, the outer cover, and the sealing rings form an isolation cavity.

[0012] Preferably, a photoluminescent film is also provided on the outer side of the outer cover.

[0013] Preferably, the outer cover body is further provided with a counterweight groove and a counterweight ring, and the counterweight ring is disposed in the counterweight groove.

[0014] Preferably, a mounting position is provided at the upper end and / or lower end of the outer cover, and the mounting position is fixedly connected to or integrally formed with the outer cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model discloses a layered, gradient-transparent lampshade, comprising an outer cover, a middle optical modulation layer, an inner diffuser, and a supporting frame. The supporting frame is disposed within the outer cover, the inner diffuser is connected to the supporting frame, and the middle optical modulation layer is disposed between the outer cover and the inner diffuser. The middle optical modulation layer is fixedly connected to the supporting frame. By setting the middle optical modulation layer, light undergoes multiple directional deflections and intensity attenuations during its transmission, thereby creating a continuous, stepless transition of light and dark from top to bottom in a macroscopic visual effect.

[0016] 2. The layered gradient light-transmitting lampshade of this utility model comprises an inner light-transmitting layer, a middle light-transmitting layer, and an outer light-transmitting layer in the middle optical modulation layer group. The inner, middle, and outer light-transmitting layers are fixedly connected to the supporting frame, and each of the inner, middle, and outer light-transmitting layers is coated with an ink layer. As light passes through the three light-transmitting layers, it undergoes multiple directional deflections and intensity attenuations, thus creating a continuous, stepless transition of light and dark from top to bottom in a macroscopic visual effect.

[0017] 3. The layered gradient light-transmitting lampshade of this utility model has an ink layer coverage of 20% for the inner light-transmitting layer, 50% for the middle light-transmitting layer, and 80% for the outer light-transmitting layer. The three light-transmitting sheets are stacked with ink layers of different coverage rates, which avoids the periodic grating effect caused by a single pattern and effectively suppresses the generation of local bright spots. 4. The layered gradient translucent lampshade of this utility model includes an upper fixed plate, a lower fixed plate, and a connecting rod in its supporting frame. The upper fixed plate is fixedly connected to the lower fixed plate via the connecting rod or is integrally formed. The supporting frame design ensures the spatial stability of the multi-layered components during long-term use, ultimately achieving a unity of high visual softness and strong artistic expression.

[0018] 5. The layered gradient light-transmitting lampshade of this utility model has slots on the upper and lower fixing plates for fixing the inner, middle, and outer light-transmitting layers. These layers are connected to the upper and lower fixing plates via these slots. The slots effectively secure the inner, middle, and outer light-transmitting layers, preventing them from detaching. 6. The layered gradient light-transmitting lampshade of this utility model has a conical structure on the inner diffuser, and the conical structure and the inner diffuser are fixedly connected or integrally formed. The conical microstructure performs initial light homogenization treatment on the light source, ensuring that the light field distribution entering the middle layer is uniform, and providing a stable input for subsequent gradient modulation.

[0019] 7. The layered gradient light-transmitting lampshade of this utility model has sealing rings at both ends of the outer light-transmitting layer. One side of the sealing ring is connected to the outer light-transmitting layer, and the other side of the sealing ring is connected to the outer cover body. The outer light-transmitting layer, the outer cover body, and the sealing rings form an isolation cavity. The isolation cavity not only reduces the heat conduction rate but also reduces material deformation caused by temperature differences, maintaining the relative positional accuracy between the optical layers.

[0020] 8. The layered gradient translucent lampshade of this utility model also has a photoluminescent film on the outer side of the outer layer. The introduction of the photoluminescent film expands the dimensions of color temperature adjustment, enabling the lampshade to exhibit rich color performance under different driving currents. 9. The layered gradient light-transmitting lampshade of this utility model has a counterweight groove and a counterweight ring inside the outer layer, with the counterweight ring set inside the counterweight groove. The counterweight ring ensures that the lampshade remains vertical when suspended, preventing tilting or swaying due to a shift in the center of gravity.

[0021] 10. The layered gradient light-transmitting lampshade of this utility model has mounting positions at the upper and / or lower ends of the outer cover, and the mounting positions are fixedly connected to or integrally formed with the outer cover. The mounting positions facilitate the installation of light bulbs or lamp holders on the lampshade. Attached Figure Description

[0031] Furthermore, in this application, the technical features described in an open-ended manner include both closed technical solutions composed of the listed features and open technical solutions that include the listed features.

[0032] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: like Figure 1-8As shown, the layered, gradient-transparent lampshade includes an outer cover 1, a middle optical modulation layer group 2, an inner diffuser 3, and a support frame 4. The support frame 4 is disposed inside the outer cover 1, the inner diffuser 3 is connected to the support frame 4, the middle optical modulation layer group 2 is disposed between the outer cover 1 and the inner diffuser 3, and the middle optical modulation layer group 2 and the support frame 4 are fixedly connected. In this embodiment, the outer cover, the middle optical modulation layer group, and the inner diffuser are all light-transmitting materials. The light source penetrates the outer lampshade from the inner diffuser from the inside out, causing the light to undergo multiple directional deflections and intensity attenuations during penetration, thereby forming a continuous, stepless transition of light and dark from top to bottom in a macroscopic visual effect. Of course, it is not limited to this; any material capable of achieving a continuous, stepless transition of light and dark from top to bottom in a macroscopic visual effect can be used.

[0033] Specifically, such as Figure 5 , 7 As shown, the intermediate optical modulation layer group 2 includes an inner light-transmitting layer 21, a middle light-transmitting layer 22, and an outer light-transmitting layer 23. These layers are fixedly connected to the supporting frame 4, and each layer is coated with an ink layer. In this embodiment, the inner, middle, and outer light-transmitting layers are all polycarbonate films. Light undergoes multiple directional deflections and intensity attenuations as it passes through these layers, resulting in a continuous, stepless transition of light and dark from top to bottom in a macroscopic visual effect. However, this is not a limitation; any material capable of achieving a continuous, stepless transition of light and dark from top to bottom in a macroscopic visual effect can be used.

[0034] Specifically, the ink layer coverage of the inner light-transmitting layer 21 is 20%, the ink layer coverage of the middle light-transmitting layer 22 is 50%, and the ink layer coverage of the outer light-transmitting layer 23 is 80%. In this embodiment, the ink is printed onto the inner, middle, and outer light-transmitting layers using screen printing. The ink layers of the inner, middle, and outer light-transmitting layers are alternately superimposed, avoiding the periodic grating effect caused by a single pattern and effectively suppressing the generation of local bright spots. Of course, this is not limited to this; other methods that can effectively suppress the generation of local bright spots can be used.

[0035] Specifically, such as Figure 7As shown, the supporting frame 4 includes an upper fixing plate 41, a lower fixing plate 42, and a connecting rod 43. The upper fixing plate 41 is fixedly connected to the lower fixing plate 42 via the connecting rod 43 or is integrally formed. In this embodiment, the arrangement of the upper and lower fixing plates allows the supporting frame to support the intermediate optical modulation layer and the inner diffuser, ensuring the spatial stability of the lampshade during long-term use, ultimately achieving a unity of high visual softness and strong artistic expression. Of course, it is not limited to this; other components that can ensure the spatial stability of the lampshade during long-term use can be used.

[0036] Specifically, such as Figure 6 As shown, the upper fixing plate 41 and the lower fixing plate 42 are provided with slots 411 for fixing the inner light-transmitting layer 21, the middle light-transmitting layer 22, and the outer light-transmitting layer 23. The inner light-transmitting layer 21, the middle light-transmitting layer 22, and the outer light-transmitting layer 23 are connected to the upper fixing plate 41 and the lower fixing plate 42 through the slots 411. In this embodiment, the slots can effectively fix the inner light-transmitting layer, the middle light-transmitting layer, and the outer light-transmitting layer, preventing them from falling off. Of course, it is not limited to this; other methods that can fix the inner light-transmitting layer, the middle light-transmitting layer, and the outer light-transmitting layer are also possible.

[0037] Specifically, such as Figure 3 As shown, a conical structure 31 is provided on the inner diffuser 3, and the conical structure 31 and the inner diffuser 3 are fixedly connected or integrally formed. In this embodiment, multiple conical microstructures are provided. The conical microstructures are used to uniformly scatter the direct light from the light source and transmit it to the outer layer in an approximately Lambertian manner, providing a uniform incident light field for the intermediate optical modulation layer group. The conical microstructures perform initial homogenization of the light source to ensure that the light field distribution entering the intermediate layer is uniform, providing a stable input for subsequent gradient modulation. Of course, it is not limited to this; other structures that can provide a stable input for subsequent gradient modulation can also be used.

[0038] Specifically, such as Figure 5 As shown, sealing rings 5 ​​are provided at both ends of the outer light-transmitting layer 23. One side of the sealing ring 5 is connected to the outer light-transmitting layer 23, and the other side of the sealing ring 5 is connected to the outer cover 1. The outer light-transmitting layer 23, the outer cover 1, and the sealing ring 5 form an isolation cavity 6. In this embodiment, the sealing ring is made of silicone or rubber, which has good weather resistance and elasticity. The isolation cavity is used to isolate the exchange of air between the inside and outside, reduce heat conduction, and suppress internal condensation caused by temperature differences, thus maintaining the clarity of the optical interface. Of course, it is not limited to this; it can be made of other materials that can reduce heat conduction and suppress internal condensation caused by temperature differences.

[0039] Specifically, such as Figure 2As shown, a photoluminescent film 11 is also provided on the outer side of the outer cover 1. In this embodiment, after the photoluminescent film is excited by the blue light emitted by the main light source, the photoluminescent film can emit yellow-green fluorescence. The yellow-green fluorescence mixes with the unabsorbed blue light to form a composite color temperature output, so that the lampshade can exhibit rich color performance under different driving currents. Of course, it is not limited to this; it can be any material that can enable the lampshade to exhibit rich color performance under different driving currents.

[0040] Specifically, such as Figure 8 As shown, the outer cover 1 also includes a counterweight groove 12 and a counterweight ring 13, with the counterweight ring 13 positioned within the counterweight groove 12. In this embodiment, the counterweight ring is made of brass. The counterweight ring ensures that the lampshade remains vertical when suspended, preventing tilting or swaying due to a shift in the center of gravity. However, this is not a limitation; any material capable of preventing tilting or swaying due to a shift in the center of gravity can be used.

[0041] Specifically, such as Figure 4 As shown, mounting positions 7 are provided at the upper and / or lower ends of the outer cover 1, and the mounting positions 7 are fixedly connected to or integrally formed with the outer cover 1. In this embodiment, the mounting positions are located at the lower end of the outer cover, and the mounting positions are fixedly connected to or integrally formed with the outer cover. The mounting positions facilitate the installation of light bulbs or lamp holders on the lamp cover. Of course, it is not limited to this; any other method that facilitates the installation of light bulbs or lamp holders on the lamp cover is acceptable.

[0042] Working principle: The light emitted from the light source first undergoes initial homogenization through the conical microstructure of the inner diffuser, forming a uniform incident light field. Subsequently, the light sequentially penetrates the inner, middle, and outer light-transmitting layers. Due to the different coverage and geometric shapes of the ink layers in these layers, and their staggered arrangement, the light experiences varying degrees of attenuation and scattering at each layer. Finally, the light passes through the outer cover, undergoes a final directional modulation, and exits. Throughout the entire light path, the light experiences multiple intensity attenuations and directional deflections, ultimately creating a continuous, stepless gradient of brightness or color on the outer surface of the lampshade from top to bottom.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
