[0002] In some of today's indoor photography and videography scenes such as live broadcast rooms, studios, and film sets, in order to make the light shining on the person or object being photographed softer, it is generally necessary to place a soft light plate between the photographic light and the person or object being photographed, so that the light emitted by the photographic light is scattered by the soft light plate before being irradiated on the person or object being photographed. In order to facilitate the adjustment of the atomization degree of the soft light plate, some electric-controlled atomization plates are now available on the market, which control the atomization degree by inputting a control current. However, since the photography and videography scenes often change in actual shooting situations, the photographic equipment often needs to be moved. However, since the overall structure of today's electric-controlled soft light plates is relatively large, they all need to be installed on a fixed frame, which makes it inconvenient to move the electric-controlled soft light plates, and the user experience needs to be improved.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0045] See also Figures 1 to 15 This embodiment provides a portable electrically controlled light softener adjustment system, comprising a portable light softener and an angle adjustment bracket 300. The portable light softener can adjust the transmittance of the electrically controlled light-switching film 100, thereby adjusting the softness of the light transmitted through the electrically controlled light-switching film 100. Furthermore, the angle adjustment bracket 300 is fixed to the support frame 200 of the portable light softener, allowing the angle adjustment bracket 300 to adjust the horizontal rotation angle and / or tilt angle of the electrically controlled light-switching film 100, thereby adapting the portable light softener to various photographic scenarios.

[0046] In some embodiments, the control component in the portable light-scaling device can be connected to an external control terminal via a wired or wireless control signal. The control terminal can be a remote control device such as a console, an app, or a remote controller. Furthermore, one control terminal can be connected to the control components (not shown) in multiple portable light-scaling devices. Therefore, an operator can input a terminal control signal to the control components (not shown) in each portable light-scaling device via the control terminal to achieve rapid and uniform adjustment of the transmittance of the electrically controlled dimming film 100. This allows the electrically controlled dimming film 100 to meet the fast pace of filming, greatly saving time and labor and improving work efficiency.

[0047] See also Figures 4 to 6 In some embodiments, the portable soft light device includes an electrically controlled dimming film 100, a supporting frame 200, and a control component (not shown).

[0048] The support frame 200 includes more than four support rods hinged in sequence, and all the support rods enclose the main frame; therefore, by swinging the support rods, the main frame can be unfolded and folded, and the main frame can be unfolded when needed; the main frame is provided with a second detachable component 205, and the side edge of the electrically controlled dimming film 100 is provided with a first detachable component 101. The electrically controlled dimming film 100 is a flexible piece, so the electrically controlled dimming film 100 can be rolled up or flattened. When in use, the electrically controlled dimming film 100 can be flattened and folded through the first detachable component 1 01 cooperates with the second detachable component 205 to be unfolded and assembled on the main frame; when storing, the electrically controlled dimming film 100 can be removed from the main frame and rolled up for storage; and the electrically controlled dimming film 100 is connected to a control component (not shown) through a conductive member 103, and a power supply is provided in the control component (not shown), which can output an operating voltage to the electrically controlled dimming film 100, so that the electrically controlled dimming film 100 displays a corresponding transmittance according to the voltage value of the operating voltage output by it, so as to change the transmittance of the electrically controlled dimming film 100.

[0049] In this embodiment, the electrically controlled dimming film 100 is a thin film made of a special material, typically consisting of a dimming layer of liquid crystal molecules sandwiched between two transparent films. The electrically controlled dimming film 100 can change the transmittance of this dimming layer using an AC voltage. This principle is based on the electrochromic effect and the shift in the alignment of liquid crystal molecules under the influence of an electric field.

[0050] When the electrically controlled dimming film 100 is powered off, the liquid crystal molecules within it align randomly, causing light to scatter in all directions, giving the dimming layer a frosted, opaque appearance. When powered on, the liquid crystal molecules align perpendicular to the dimming layer, allowing light to pass through smoothly, rendering the dimming layer transparent. This transition between transparent and opaque states occurs instantaneously, achieving the desired haze and clarity effects of the electrically controlled dimming film 100. Furthermore, by varying the voltage input to the electrically controlled dimming film 100, the transmittance of the electrically controlled dimming film 100 can be gradually altered. Moreover, the liquid crystal molecules in the dimming layer can be white, black, red, green, blue and other colors. When powered on, the dimming layer is transparent, and as the voltage decreases, the corresponding color of the liquid crystal molecules will gradually be displayed in the dimming layer. Therefore, when the liquid crystal molecules in the dimming layer are white, the electrically controlled dimming film 100 can be used as a soft light sheet, and when the liquid crystal molecules in the dimming layer are colored, the electrically controlled dimming film 100 has a color filtering function in addition to the soft light function.

The control component (not shown) controls the transmittance of the electrically controlled dimming film 100 based on the terminal signal to adapt it to different shooting scenarios. The control component (not shown) is disposed in a control box body 401, and the control box body 401 is fixedly mounted on the front edge of the electrically controlled dimming film 100.

[0052] In some other embodiments, the control component (not shown) is arranged in the control box body 401, and the control box body 401 is arranged on the outside of the electric control dimming film 100 through a cable, which makes it convenient for the user to hold the control box body 401 for operation and control. The user can directly input the control signal on the control box body 401, or input the control signal to the control box body 401 through the control terminal.

[0053] In some other embodiments, the control terminal or control component (not shown) can be directly programmed to enable the control component (not shown) to fully automatically control the transmittance of the electrically controlled dimming film 100. For example, the transmittance of the electrically controlled dimming film 100 can be controlled by an automated program so that the transmittance of the electrically controlled dimming film 100 changes at regular intervals.
