ーとして使用している。 Furthermore, as a drive circuit for a variable reflectance mirror using EC, a configuration shown in FIG. 9 is known. In FIG. 9, 30 is an EC drive power supply circuit;
31 is an EC mirror, and 32 is a manually operated switch with 2 contacts and 3 circuits. The same configuration is switch 32
When the first switching circuit () is in the state shown and the second switching circuit (), () is also in the state shown,
A voltage is applied to the EC mirror 31 by power supply from the EC drive power supply circuit 30, and the EC mirror 31 becomes colored. That is, the reflectance of the EC mirror 31 is reduced to prevent dazzling caused by light irradiated from behind. Further, by switching the switch 32 and connecting the respective switch contacts in the opposite direction to that shown in the figure, the voltage is no longer applied to the EC mirror 31, and the EC mirror 31 is brought into a decolorized state.

ち、防眩状態となる。 Next, the operation of the circuit shown in FIG. 1 will be explained. FIG. 1 shows the state before the power switch is turned on, and each relay contact is in the connected state shown. Now, when the EC drive power supply circuit 2 and the relay coil drive power supply 6 are turned on and the manual switch 16 is switched to the contact b side, the relay contacts 7, 8, and 11 become contact b by the output signal of the relay coil output circuit 5.
A coloring voltage V 1 is applied to the EC mirror 1, a coloring reaction occurs, and the reflectance of the EC mirror 1 decreases. In other words, it becomes an anti-glare state.

つ。 The amount of charge flowing through the EC mirror 1 is determined by the charge amount discrimination circuit 3, and when the amount of charge reaches the amount of charge preset by the external charge amount regulator 4, an electrical signal is sent to the relay coil output circuit. 5, the relay coil output signal is cut off, and the relay contacts 7, 8, and 11 return to the contact a side. Therefore, the EC mirror 1 maintains the set reflectance state.
なお、電荷量判別回路３はECミラー１の大き

に固定しても良い。 In addition, the charge amount discrimination circuit 3 examines the relationship between the charge amount and reflectance in advance according to the size of the EC mirror 1, and adjusts the charge amount so that the user (driver) can select the desired reflectance. All you have to do is adjust the device 4. Of course, the manufacturer may fix the setting value to suit the purpose of use.

ECセルの構造によつてそれぞれ異なる。 In general, in EC materials, the amount of charge injection and reflectance (transmittance) are linearly proportional to each other depending on the size of the EC area, and are not affected by ambient temperature. In addition, the coloring voltage V 1 and decoloring voltage V 2 are based on the type of EC material.
Each differs depending on the structure of the EC cell.
そして、手動スイツチ１６を接点ａに戻すと、
リレー接点１２は接点ｂ側となり、ECミラー１

Relay contact 12 is on the contact b side, and EC mirror 1
A decoloring voltage V 2 is applied to the surface, and a decoloring reaction occurs, returning the reflectance to its original value.

１は非防眩状態となる。 According to the same configuration, when the headlight light of the following car is irradiated as external light, the external light detection sensor 27 detects it, the amplification circuit 28 amplifies the detection signal, and the light amount determination circuit 29 detects it. Discrimination control is performed. Here, the light amount determination circuit 29 has been adjusted by the adjuster 50 to determine whether or not the light reflected by the EC mirror 1 is such that the driver feels dazzled, and accordingly outputs a signal. Then, when there is an output voltage from the relay coil output circuit 51 and the relay coil 52 is excited, the relay contact 3
3 is switched to the contact b side, relay contacts 7, 8, and 11 are switched to the contact b side by the output signal of the relay coil output circuit 5, and a coloring voltage V1 is applied to the EC mirror 1, causing a coloring reaction. The reflectance of the EC mirror 1 decreases. That is, instead of the manual switching operation shown in FIG. 1, an automatic switching operation is performed and the anti-glare state is automatically established. After that, when the light emitted from the following vehicle disappears, the relay contact 33 becomes the state shown in the figure due to the action of the external light detection sensor 27, and the EC mirror 1 becomes the non-dazzling state.

As is clear from the above-mentioned embodiments, according to the present invention, the EC mirror is controlled by the charge amount discrimination circuit, regulator, relay coil output circuit, and relay contact circuit provided between the EC mirror and the EC drive power supply circuit. Since it is configured to automatically set the reflectance, it is easy to control the setting of the EC mirror reflectance, and the desired reflectance can be obtained with the amount of charge set by the driver without being affected by the temperature characteristics of the EC. It is possible to prevent deterioration of EC materials due to excessive coloring, and it can also be used as an auto-dimming mirror for automobiles to reduce glare, which varies depending on the physiology of the eyeballs and the psychological level of dazzle of individual people, as well as the level of surrounding brightness. It has the effect of being able to absorb differences and greatly contributing to safe driving.
