Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting devices, in particular to a smart light control wall lamp integrated with an electrically controlled light modulation film, which has a dynamic optical property adjustment function and is particularly suitable for indoor and outdoor scenes that require both atmosphere creation and privacy protection. BACKGROUND

[0002] The electrically controlled light modulation film (EC film) is a functional material that controls the light transmittance through voltage. When powered on, it is in a transparent state, and when powered off, it is in a fogging state. This technology has been mainly applied to building curtain walls, vehicle windows and other large-area glass scenes to achieve sun shading and privacy protection by changing the light transmittance state. However, there are three major challenges in integrating it into small lamps: 1. Structural adaptability: the driving module of the building-level EC film is large in size and difficult to implant in the limited space of the lamp; 2. Optical interference: the light source of the lamp itself easily interferes with the reading of the ambient light sensor, leading to false triggering; 3. Process compatibility: the film layer fitting of the curved / multi-faceted glass lampshade needs to solve the problems of air bubbles and edge warping.

[0003] There are mainly two types of technical solutions for the wall lamps currently on the market: one is the traditional fixed wall lamp, which uses a single layer of glass or acrylic lampshade, and the optical state is unchangeable, and the light modulation depends only on the brightness adjustment of the light source (such as LED color temperature adjustment), and the physical transmittance of the lampshade cannot be changed. The second type is a smart induction wall lamp, which is equipped with a human body / light sensor, but the function is limited to switching on / off or brightness adjustment. Moreover, the lampshade is static and fixed, and cannot realize transparent-fogging switching, lacking the dynamic balance ability of atmosphere and privacy.

[0004] The core defects of the above prior art are: 1. The transmittance of the lampshade of the traditional wall lamp is fixed, and the user needs to choose between "clear display of filaments" (transparent) and "soft shading" (fogging), and cannot dynamically switch between the two; 2. Direct transplantation of building EC technology will result in problems such as large size of the driving module, visible seams of the glass, air bubbles in the film layer fitting, etc.; 3. The light sensor is disturbed by the self-light of the filament, and frequently malfunctions in the twilight / short shadow.

[0005] In summary, the technical problems to be solved by the present application are: how to reliably integrate the electrically controlled light modulation film into a small wall lamp to realize transparent / fogging dual-state switching of the lampshade, and at the same time solve the problems of glass seam-free assembly, film layer bubble-free fitting, light sensor anti-interference, and driving module miniaturization through structural optimization. SUMMARY

[0006] The present application aims at the three defects of the existing wall lamp, i.e., the light transmission state of the lampshade cannot be adjusted, the electric control dimming film is difficult to be miniaturized and integrated, and the ambient light sensor is easy to be disturbed, and provides an intelligent light control wall lamp integrated with an electric control dimming film. The following technical problems are mainly solved: 1. Dynamic switching of the glass lampshade between the transparent state (clear display of the filament) and the fogging state (uniform soft light) is realized; 2. The integration bottleneck of the electric control dimming film in a small lamp is broken through, and the film layer is ensured to be bubble-free and the glass is ensured to be assembled without traces; 3.
