j, is obtained, and this voltage acts on the liquid crystal plate 4 of the rearview mirror 3, which is entirely coated with gold. When the output voltage E of the first solar cell 1 is large, the transmission of the liquid crystal plate 4 is lowered to reduce the reflectance of the rearview mirror 3, and nine reflected lights A'ffi are reflected for each incident light, so that the driver can What is shown in Figure 2 is a circuit diagram of another embodiment of the present invention.The circuit shown in Figure 2 is a circuit diagram of another embodiment of the present invention. At the same time as detecting the incident light A't! The output voltage E1 of the solar cell 1, which is converted into atmospheric energy, is input to a circuit 6 that fully drives the liquid crystal panel 4 covering the entire surface of the rearview mirror 3. Also, a light/direct conversion element (for example, a solar cell, a phototransistor) that detects the entire illuminance of light B at ambient brightness.

The drive circuit 6 is driven by the power generated by the solar cell 1 and outputs an amount inversely proportional to the brightness of the surrounding light B, changes the transmittance of the liquid crystal plate 4 of the rearview mirror 3, and changes the reflectance of the rearview mirror 30. It controls and reflects the reflected light h/ to the incident nine people, causing glare to the driver? It works so that you don't feel it.

駆動することができる。<Effects of the Invention> According to the auto-dimming mirror of the present invention, the transmittance of the liquid crystal plate covered with gold on the entire rearview mirror is proportional to the difference between the amount of light A in the rear view of the rearview mirror and the amount B of the surrounding brightness. By controlling this voltage, as the amount of light in the rear view increases, the total transmittance of the liquid crystal panel is lowered, and the reflectance of the rearview mirror 3 is reduced to prevent glare. In this way, since the anti-glare mechanism makes full use of the liquid crystal, which operates with extremely low power, the liquid crystal can be sufficiently driven by the energy generated by the solar cell from the amount of light A in the rear view of the rearview mirror.

簡単になった。Therefore, unlike the conventional mirror, the self-excited anti-glare mirror of the present invention does not require the use of a pantry power source, and also eliminates the need for wiring for this purpose. Therefore, the groove end of the auto-dimming mirror of the present invention is not only clean, but also the work of installing it on the vehicle body is extremely simple.
