[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, top, bottom, side...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0035] In addition, the descriptions involving "first", "second", etc. in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

[0036] In view of the technical defects existing in the prior art, this embodiment provides a dimming device. Figure 1 As shown, the dimming device of this embodiment includes a fixed component 100, an electronic dimming mirror 200 and a control device. The fixed component 100 is used to form the main body of the entire dimming device, and is used to install the electronic dimming mirror 200 and the control device. Specifically, the fixed component 100 is formed with a light-transmitting hole, and the electronic dimming mirror 200 is arranged in the fixed component 100. The electronic dimming mirror 200 arranged in the fixed component 100 is exposed to the fixed component 100 through the light-transmitting hole, so that the electronic dimming mirror 200 can reduce the amount of light passing through the light-transmitting hole, so that the dimming device of this embodiment plays a dimming role.

[0037] The control device is electrically connected to the electronic dimming mirror 200 to adjust the light transmittance of the electronic dimming mirror 200. The electronic dimming mirror 200 has a first substrate and a second substrate stacked together, and a first conductive layer and a second conductive layer are formed on the opposite surfaces of the first substrate and the second substrate. The first conductive layer and the second conductive layer are electrically connected to the first signal terminal and the second signal terminal respectively, and the periphery of the first substrate and the second substrate is sealed with a frame glue, and the gap between the first substrate and the second substrate is filled with liquid crystal.

[0038] The first signal terminal and the second signal terminal are electrically connected to the control device, so the user can adjust the phase of the liquid crystal through the control device to control the transmittance of the electronic dimming filter 200. Specifically, the control device can generate a driving signal corresponding to a certain transmittance, and the driving signal will be transmitted to the first conductive layer and the second conductive layer to generate an electric field between the two. Therefore, the liquid crystal filled in the liquid crystal panel can be affected by the electric field to change the arrangement of its liquid crystal molecules, thereby changing the transmittance of the electronic dimming filter 200 to achieve the effect of adjusting the dimming value.

[0039] Compared with the dimming device in the prior art, the dimming device of this embodiment adopts an electronic dimming filter 200. Since the electronic dimming filter 200 adjusts the transmittance of the glass by changing the phase of the liquid crystal in the glass by voltage, the problem of color deviation can be improved.

[0040] Furthermore, if Figure 1 and Figure 2As shown, in order to realize wireless control of the light transmittance of the electronic dimming mirror 200, the control device includes a controller 310 and a wireless receiver 320. The controller 310 is mounted on the fixed component 100 and is electrically connected to the wireless receiver 320 and the electronic dimming mirror 200 respectively. The wireless receiver 320 is mounted on the side of the fixed component 100 and at least partially protrudes outside the fixed component 100. Preferably, the wireless receiver 320 is a radio frequency antenna mounted on the side of the fixed component 100, and the wireless receiver 320 can receive a wireless control signal transmitted by a user's control terminal (such as a smart phone, a remote control, a tablet computer, etc.). The wireless receiver 320 is used to receive the wireless control signal and feed it back to the controller 310. When the controller 310 receives the wireless control signal, it generates a corresponding driving signal to control the light transmittance of the electronic dimming mirror 200, thereby achieving the purpose of remotely controlling the electronic dimming mirror 200.

[0041] Furthermore, if Figure 1 and Figure 2 As shown, in order to manually control the light transmittance of the electronic dimming filter 200, the control device further includes a manual control member 330. The manual control member 330 is mounted on the side of the fixed member 100 and is electrically connected to the controller 310. The controller 310 is also used to adjust the light transmittance of the electronic dimming filter 200 according to the signal fed back by the manual control member 330. Preferably, the manual control member 330 is a pulsator knob mounted on the side of the fixed member 100. The pulsator knob is electrically connected to the controller 310 through a variable resistor. By rotating the pulsator knob, the resistance change of the variable resistor can be adjusted, so that the driving voltage generated by the controller 310 can be adjusted, thereby adjusting the phase of the liquid crystal, thereby controlling the light transmittance of the electronic dimming filter 200.

[0042] Furthermore, in order to more intuitively observe the light transmittance of the electronic neutral density filter 200, as shown in FIG. Figure 1 As shown, the dimming device also includes a display screen 400. The display screen 400 is mounted on the side of the fixed component 100 and is electrically connected to the control device. When the control device generates a driving signal for controlling the electronic dimming mirror 200, it also generates a display signal corresponding to the driving signal, and transmits the display signal to the display screen 400, so that the display screen 400 displays the current transmittance of the electronic dimming mirror 200. Furthermore, a power supply interface 500 is also provided on the side of the fixed component 100, and the power supply interface 500 is electrically connected to the control device, and is used to cooperate with a power data line independent of the dimming device to supply power to the control device. The power supply interface 500 is preferably a Type-C socket, but is not limited thereto.

[0043] Furthermore, if Figure 2As shown, the fixing member 100 includes two mutually connected frames 110, and the two frames 110 are respectively penetrated with a first hollow inner hole 111, and the first hollow inner holes 111 of the two frames 110 are coaxially arranged to form a light-transmitting hole. Among them, the control device also includes a circuit board 340, and the circuit board 340 is sandwiched between the two frames 110, and the controller 310 is arranged on the circuit board 340. The circuit board 340 is provided with a mounting hole 341, and the electronic dimming filter 200 is installed in the mounting hole 341.

[0044] In another embodiment, a dimming component is provided. The dimming component can be detachably mounted on one axial end of the camera to adjust the amount of light entering the camera, thereby improving the shooting effect of the camera. The dimming component of this embodiment includes the dimming device provided in the above embodiment and an adapter ring 600 used in conjunction with the dimming device.

[0045] like Figure 3 As shown, the adapter ring 600 is formed with a second hollow inner hole 610, and a slot 620 connected to the second hollow inner hole 610 is opened on the circumference of the adapter ring 600. A connecting member for connecting to a camera head is provided on one side of the adapter ring 600 in the axial direction. Optionally, the connecting member can be a threaded connection part or a magnetic connection part, but is not limited thereto. Figure 4 As shown, the dimming device is installed in the second hollow inner hole 610 through the slot 620, so that the dimming device and the adapter ring 600 are combined to form a dimming assembly. When the dimming assembly of this embodiment is connected to a camera, the dimming device can reduce the amount of light passing through the second hollow inner hole 610, thereby reducing the amount of light entering the camera to improve the shooting effect of the camera.

[0046] Further, continue to refer to Figure 4 As shown, a handle 120 is protruded from the side of the fixing member 100 of the dimming device. The handle 120 is protruded outside the slot 620 for a person to hold the dimming device by hand, so as to insert the dimming device into the slot 620 of the adapter ring 600, or to pull out the dimming device from the slot 620 of the adapter ring 600.

[0047] Furthermore, combined with Figure 2 As shown, in order to improve the connection stability between the dimming device and the adapter ring 600, an elastic positioning member 130 is provided on the side of the fixing member 100, and a positioning hole is provided on the inner circumferential wall of the adapter ring 600. The elastic positioning member 130 and the positioning hole cooperate with each other to position the adapter ring 600 and the dimming device. Of course, the elastic positioning member 130 can also be provided on the inner circumferential wall of the adapter ring 600, and the positioning hole is provided on the side of the fixing member 100. Optionally, the elastic positioning member 130 of this embodiment can be a ball head column race, but is not limited thereto.

[0048] Further, continue to combine Figure 1 As shown, the two axial end faces of the fixing member 100 are respectively provided with dustproof gaskets 700 located at the periphery of the light transmission hole, and the slot 620 has two slot side walls arranged opposite to each other at intervals. The dustproof gaskets 700 on the two axial end faces of the fixing member 100 are respectively in contact with the two slot side walls to seal the matching gap between the two axial end faces of the fixing member 100 and the two slot side walls, thereby preventing dust from entering.
