The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0025] Example:

[0026] like Figure 1 , 2 As shown, an electronically controlled membrane wall light includes a main body 1 and a support mechanism 2. The support mechanism 2 is connected to the main body 1. A lamp body 3 is installed on the support mechanism 2. A positioning mechanism 4 is also installed on the support mechanism 2. A lamp cover 5 is detachably installed on the positioning mechanism 4. The lamp cover 5 is used to change its transparency in different states.

[0027] In one embodiment, the lampshade 5 is a polymer-dispersed liquid crystal film structure, which includes an interlayer in which liquid crystal microdroplets are dispersed in a solid polymer matrix.

[0028] In one implementation, the lampshade 5 is connected to an electronic control module, which controls the refractive index matching state of the liquid crystal droplets by applying or disconnecting an electric field, so as to switch the transparency and fogging effects of the lampshade 5.

[0029] In one implementation, the electronic control module includes transparent electrodes symmetrically distributed on both sides of the lampshade 5. The electrodes are arranged in a grid or strip pattern to achieve a uniform electric field distribution.

[0030] In one embodiment, the polymer-dispersed liquid crystal film of the lampshade 5 is encapsulated between two transparent protective layers, which are made of tempered glass or polycarbonate.

[0031] In one implementation, the electronic control module integrates a wireless communication unit to receive control signals from an external smart home system, enabling remote switching of the transparent state of the lampshade 5.

[0032] In one implementation, the positioning mechanism 4 includes a snap-fit ​​structure for quick assembly and disassembly of the lampshade 5.

[0033] In one implementation, the snap-fit ​​structure is a U-shaped positioning frame, and the U-shaped positioning frame has a positioning groove 41, and the lampshade 5 is snap-fitted into the positioning groove 41.

[0034] In one embodiment, the support mechanism 2 includes a horizontal support arm 21, a ball joint 22, and a vertical support arm 23. One end of the support arm 21 is rotatably connected to the main body 1, and the other end of the support arm 21 is connected to the vertical support arm 23 through the ball joint 22. A lamp body 3 is mounted on the horizontal support arm 21, and the vertical support arm 23 is used to support the fixed positioning mechanism 4.

[0035] The working principle of this invention: The core working principle of this product is based on the synergistic effect of polymer dispersed liquid crystal (PDLC) technology and an electronic control module. The transparency of the lampshade is controlled by an electric field, achieving flexible switching between transparent and atomized states. The specific process is as follows:

[0036] Structure and optical properties of the PDLC film: The lampshade 5 is composed of a PDLC film, in which liquid crystal microdroplets (5-10 μm in diameter) are uniformly dispersed in a solid polymer matrix (such as epoxy resin or polyurethane). In the power-off state, the liquid crystal molecules are randomly arranged, and the optical axes of the microdroplets are randomly distributed, resulting in a mismatch between the refractive index and the matrix. Incident light undergoes multiple scattering upon passage, causing the lampshade to appear foggy (opaque), softening and diffusing the light to avoid glare. In the power-on state, the electronic control module applies a uniform electric field, driving the liquid crystal molecules to reorient. The optical axes of the microdroplets align with the direction of the electric field, and the refractive index of the liquid crystal matches the matrix, allowing light to pass through in a straight line. The lampshade becomes transparent, significantly improving light transmittance.

[0037] The electric field control mechanism of the electronic control module: The electronic control module forms an electric field through transparent electrodes (such as ITO conductive layers or silver nanowire electrodes) symmetrically distributed on both sides of the PDLC film. The electrodes are designed in a grid, strip, or rhomboid layout to ensure uniform electric field distribution and shorten response time (as low as 0.5 seconds). The power supply circuit of the electronic control module can dynamically control the on / off state of the electric field according to user commands or sensor signals (such as photosensors, temperature controllers), realizing rapid switching of the lampshade state. For example:

[0038] Intelligent control scenario: By integrating a wireless communication unit (Wi-Fi, Bluetooth or RF), users can remotely send commands to switch between transparent and fogged states, and adjust the color temperature and brightness of the lamp body 3 in conjunction with the control.

[0039] Environmentally adaptive scenarios: Built-in sensors (such as photosensors and rain sensors) trigger automatic switching, such as switching to a fogging state in rainy weather to prevent water stains and reflections, and switching to a transparent state in dark environments to enhance light transmission.

[0040] Example 2:

[0041] This embodiment is basically the same as Embodiment 1, except that it provides an electrically controlled membrane wall lamp suitable for home environments. Its specific structure includes a main body 1, a support mechanism 2, an LED lamp body 3, a magnetic adsorption positioning mechanism 4, and a PDLC lampshade 5. The support mechanism 2 is a metal bracket fixed to the wall with bolts. The main body 1 has a built-in power module and control circuit. The lampshade 5 adopts a PDLC film sandwich structure, with tempered glass protective layers on both sides, 3mm thick, and an anti-fingerprint coating on the surface. The liquid crystal microdroplets inside the PDLC film have a diameter of 5-10μm, the substrate is epoxy resin, and strip-shaped ITO transparent electrodes are provided on both sides with a 2mm electrode spacing to ensure uniform electric field distribution. The electrical control module integrates a Wi-Fi communication unit, connecting to a home smart gateway, allowing users to remotely control the lampshade's transparency and fogging switching via a mobile app. The LED lamp body 3 uses an RGBW four-color light source with a color temperature range of 2700K-6500K and brightness adjustable from 0-100%. The system presets scenarios such as "Reading Mode" (transparent lampshade + 4000K white light) and "Ambient Mode" (fog lampshade + 2700K warm light + color gradient), and the lampshade status is linked to the light source parameters. For example, when switching to the fog mode, the brightness is automatically reduced by 30% to reduce glare. The positioning mechanism 4 uses a combination of neodymium iron boron magnets and metal guide plates, and the lampshade can be disassembled and installed with one hand for easy cleaning or replacement. This embodiment significantly improves the comfort and aesthetics of home lighting through intelligent control and adaptive light effects.

[0042] Example 3:

[0043] This embodiment is basically the same as Embodiment 1, except that it designs a high-durability electrically controlled membrane wall lamp for hotel lobbies. The main body 1 is an aluminum alloy shell with an anodized surface. The support mechanism 2 is a rotatable bracket that supports angle adjustment of the lamp body 3. The lampshade 5 adopts a PDLC film sandwich structure with a polyurethane substrate. The electrodes on both sides are designed as diamond-shaped grid-like ITO layers with an electrode line width of 0.1mm and a spacing of 1.5mm to ensure rapid response (switching time < 0.5 seconds). The transparent protective layer is made of impact-resistant polycarbonate, 2mm thick, and coated with an anti-UV coating. The electrical control module has built-in Bluetooth Mesh networking functionality, allowing it to connect to a central control system for synchronized switching of multiple lamps. For example, during events, all wall lamps switch to transparent mode, creating a bright, cool white light (6000K) to create a transparent atmosphere; during daily operation, they switch to a misting mode, outputting soft, warm light (3000K). The lamp body 3 uses COB-packaged LED modules with a luminous efficacy of 120lm / W and a lifespan of 50,000 hours. The positioning mechanism 4 is a snap-fit ​​structure, and the lampshade edge is equipped with a silicone sealing ring, with an IP54 protection rating, suitable for high-traffic environments. Furthermore, the system supports light sensor linkage; when the ambient light level is below 50 lux, it automatically switches to a transparent state to improve light transmittance. This embodiment, through highly reliable design and dynamic light effect management, meets the dual functional and aesthetic requirements of commercial spaces.

[0044] Example 4:

[0045] This embodiment is basically the same as Embodiment 1, except that it provides a semi-outdoor electrically controlled membrane wall lamp suitable for balconies or corridors. The main body 1 uses a die-cast aluminum shell with an anti-corrosion coating. The support mechanism 2 is an L-shaped bracket with an IP65 waterproof rating. The lampshade 5 is composed of a PDLC film and double-layered tempered glass, with a glass thickness of 4mm and silicone edging. It is filled with inert gas to isolate moisture. The PDLC film substrate is weather-resistant acrylic resin, with nano-anti-aging agents added to the liquid crystal microdroplets. The electrodes use a silver nanowire transparent conductive film with a resistivity <10Ω / sq, and can withstand temperature changes from -20℃ to 60℃. The control module integrates a 433MHz RF receiver, supports waterproof remote control operation, and includes buttons for "transparent," "fog," and "automatic mode." The lamp body 3 uses a high color rendering LED (CRI>90) with a fixed color temperature of 4000K and a maximum brightness of 2000lm. It has a built-in temperature sensor that automatically reduces power when the lamp body temperature exceeds 60℃. The positioning mechanism 4 is a sliding rail structure with T-shaped guide grooves on both sides of the lampshade, allowing for lateral sliding adjustment of the illumination angle along the bracket. In "automatic mode," the system makes decisions based on data from built-in photosensors and raindrop sensors: automatically switching to a fogging state in rainy weather to avoid water stain reflection, and switching to a transparent state at night in dark environments to maximize light transmission. This embodiment ensures stable operation and functionality under complex outdoor conditions through enhanced protection and intelligent environmental response.
