Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a lampshade with adjustable light transmittance. Background Technology

[0002] As an important interior decoration and lighting device, lamps play a vital role in creating spatial atmosphere through their appearance design and light performance. Artistic lampshades, through their unique shapes, materials, and light transmission characteristics, can achieve rich light and shadow art effects and are widely used in homes, commercial spaces, and public environments.

[0003] By selecting materials with different light transmittance or by applying special treatments to the surface of the lampshade, it is possible to achieve soft diffusion, local focusing, or gradual transition of light, thereby enhancing the visual aesthetics and artistic expression of the lamp. Some artistic lampshades also incorporate multi-layered structures, rotatable components, or external light-shielding parts to achieve dynamic changes in light and shadow and diverse lighting modes.

[0004] However, most existing art lampshades are made of materials with fixed light transmittance, and their light output effect is determined after installation. Although the brightness of the light source can be adjusted by an external dimming switch, the light transmittance area or degree of light transmittance of the lampshade itself cannot be adjusted. Therefore, in scenarios where the light distribution pattern needs to be changed according to the environment or usage requirements, the flexibility of its light control is limited.

[0034] 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.

[0035] 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 1-8 As shown, the adjustable light transmittance lampshade includes a fixed base 1, an adjustment component 2, and a driving component 3. The adjustment component 2 is mounted on the fixed base 1, and the driving component 3 is also mounted on the fixed base 1. The driving component 3 drives the adjustment component 2 to adjust the light transmittance. In this embodiment, the driving component drives the adjustment component to adjust the light transmittance, thereby achieving dynamic light and shadow changes and diverse lighting modes. This effectively solves the problem of fixed light transmittance in the lampshade, which prevents adjustment of the light distribution pattern according to needs. Of course, it is not limited to this; other components capable of adjusting light transmittance can also be used.

[0036] Specifically, such as Figure 2 , 5 As shown, the adjustment component 2 includes an inner lampshade 21, a connecting frame 22, and a grating cover 23. The inner lampshade 21 is disposed inside the connecting frame 22, and the grating cover 23 is disposed outside the connecting frame 22. In this embodiment, the light transmittance of the grating cover is adjusted by driving the driving component to change the overall light transmittance of the lampshade. Of course, it is not limited to this; any other component capable of changing the overall light transmittance of the lampshade can be used.

[0037] Specifically, the grating cover 23 includes an upper ring 231, grating pillars 232, and grating sheets 233. The upper ring 231 is connected to the upper end of the connecting frame 22, the grating pillars 232 are rotatably connected to the upper ring 231, and one end of the grating sheet 233 is rotatably connected to the grating pillars 232. In this embodiment, eight grating pillars and eight grating sheets are provided. The cross-sectional shape of the grating sheet is a teardrop shape, narrow at one end and wide at the other. The narrow end of the grating sheet is rotatably connected to the grating pillars. By rotating the grating pillars, the grating sheets rotate relative to the grating pillars, thereby changing the light transmission gap between the grating pillars and thus changing the overall light transmittance of the lamp cover. Of course, it is not limited to this; any other device capable of changing the light transmission gap between the grating pillars can be used.

[0038] Specifically, the connecting frame 22 includes an upper frame 221, a lower frame 222, and connecting posts 223. One end of the connecting post 223 is fixedly connected to the upper frame 221, and the other end of the connecting post 223 is fixedly connected to the lower frame 222. In this embodiment, eight connecting posts are provided to improve the overall stability of the connecting frame. By setting the connecting frame, it can support the grating cover and the inner lamp cover, improving the overall rigidity of the lamp cover. Of course, it is not limited to this; any other material capable of supporting the grating cover and the inner lamp cover can be used.

[0039] Specifically, such as Figure 5 , 6 As shown, the driving assembly 3 includes a driving gear 31, a driven gear 32, and an adjusting lever 33. The driving gear 31 is mounted on the fixed base 1 and is rotatably connected to the fixed base 1. The driven gear 32 is meshed with the driving gear 31 and is fixedly connected to the grating column 232. The adjusting lever 33 is fixedly connected to the driving gear 31. In this embodiment, by adjusting the lever to rotate the driving gear, the driving gear drives the driven gear to rotate, and the driven gear drives the grating column to rotate, thereby changing the light transmittance of the lampshade by changing the light transmission gap between the grating columns through the grating sheet. Of course, it is not limited to this; other components capable of driving the grating column to rotate may also be used.

[0040] Specifically, such as Figure 3 , 6 As shown in Figure -8, a limiting component 4 is also provided between the fixed base 1 and the drive gear 31. The limiting component 4 includes a limiting groove 41, a limiting bead 42, and a blind hole 43. The limiting bead 42 matches the limiting groove 41, and the limiting bead 42 matches the blind hole 43. The blind hole 43 is provided on the fixed base 1, the limiting bead 42 is provided in the blind hole 43, and the limiting groove 41 is provided on the drive gear 31. In this embodiment, when the adjusting lever is rotated to drive the drive gear to rotate, the limiting bead rolls on the drive gear. When the limiting bead rolls to the position of the limiting groove, it will be inserted downward into the positioning groove, and the adjusting lever will be stably locked at a specific angle. Of course, it is not limited to this; other components that can achieve the limiting function can be used.

[0041] Specifically, an elastic element 44 is provided within the blind hole 43. One end of the elastic element 44 is connected to the blind hole 43, and the other end is connected to the limiting bead 42. In this embodiment, when the limiting bead rolls to the position of the limiting groove, the limiting bead will be inserted downward into the limiting groove under the action of the elastic force of the elastic element. During the rolling process or the stationary process, the elastic element will have a downward pushing force, which improves the limiting ability of the limiting bead. Of course, it is not limited to this; any other element that can exert a downward pushing force on the limiting bead can be used.

[0042] Specifically, such as Figure 2 As shown, a mounting groove 224 for installing the inner lampshade 21 is provided within the connecting frame 22, and the mounting groove 224 matches the inner lampshade 21. In this embodiment, the mounting groove makes it less likely for the inner lampshade to fall off when installed on the connecting frame. Of course, it is not limited to this; other methods that facilitate the installation of the inner lampshade can be used.

[0043] Specifically, such as Figure 4As shown, a connecting component 5 is also provided between the upper ring 231 and the connecting frame 22. The upper ring 231 is connected to the connecting frame 22 through the connecting component 5. The connecting component 5 includes a connecting protrusion 51 and a connecting groove 52. The connecting protrusion 51 and the connecting groove 52 are matched. The connecting protrusion 51 is disposed on the upper ring 231, and the connecting groove 52 is disposed on the connecting frame 22, or the connecting protrusion 51 is disposed on the connecting frame 22, and the connecting groove 52 is disposed on the upper ring 231. In this embodiment, the cooperation of the connecting groove and the connecting protrusion makes the installation process of the upper ring simpler and more convenient. Of course, it is not limited to this; any other method that can make the installation process of the upper ring simpler and more convenient can be used.

[0044] Working principle: During use, the user rotates the drive gear by adjusting the lever. The drive gear drives the grating column to rotate, and the grating column drives the grating sheet to rotate relative to the grating column, thereby changing the light transmission gap between the grating columns and thus changing the overall light transmittance of the lampshade. When the adjustment lever is rotated to drive the drive gear, the limiting bead rolls on the drive gear. When the limiting bead rolls to the position of the limiting groove, the limiting bead will be inserted downward into the limiting groove under the elastic force of the elastic element, and will be inserted into the positioning groove, thus stably locking the adjustment lever at a specific angle.

[0045] 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.

[0046] 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.
