Embodiment 1
[0028] As shown in the figure, the automatic anti-glare device provided by this embodiment includes a fixed bracket, a filter plate and a control circuit; the fixed bracket is fixed on the frame; the filter plate is arranged on the fixed bracket; the filter plate It includes a main body 1, a light-changing sheet, a light guide pipe 2 and a photosensitive part; the photosensitive part of this embodiment can use a photosensitive element 5;
[0029] The light pipe 2 is arranged on the main body 1 at the intersection of the observer's eye line of sight according to the eye angle 4; the axial direction of the light pipe 2 is arranged along the direction of the incident light; the eye angle 4 is the light emitted by the light source. The angle between the light 24 that enters the observer's eyes and the line of sight directly ahead of the observer's eyes; the light-changing sheet is arranged on the main body; the light-changing sheet is connected with the control circuit;

Embodiment 2
[0059] The main body provided in this embodiment is made of transparent material, which can be transparent glass or transparent organic plastic; The pressing or pasting method is combined with the main body; the transparent film layer is divided into several areas according to the actual situation, each area is connected to the control circuit, and the light transmittance of each area is adjusted through the control circuit, and each area can be adjusted by changing the refractive index. To achieve the size of the light transmittance, the size of the light transmittance can also be realized by changing the color or grayness of each area.
[0060] The dimming area can be set as a first dimming area and a second dimming area; the first dimming area is the neighborhood where the line connecting the light source and the observer's left eye intersects with the subject; the second dimming area The domain is the neighborhood where the connection line between the light source and the ...
Embodiment 3
[0078] In the anti-glare dynamic monitoring device provided in this embodiment, the controller is also provided with a transmittance recovery module; the transmittance recovery module restores the transmittance of the light-changing area after receiving a signal that the transmittance intensity needs to be restored. The signal for restoring light transmittance intensity can be actively generated through a button, or can be controlled by a preset time value; when the dimming time of the dimming area is maintained according to the preset time threshold, the restoring signal is generated.
[0079] The rearview mirror provided by this embodiment can be provided with a detection field, which is the neighborhood where the light entering the viewer's eyes after being reflected by the rearview mirror and the intersection of the rearview mirror; It is arranged in the detection area on the rearview mirror; the axial direction of the light guide pipe is arranged along the direction of the...
