摘要： A dazzle-free reflection mirror, which may be used as an inner mirror or an outer mirror of a vehicle, has an electro-optical element of which transparency is changed by applying an electric field thereto in order to effectuate a dazzle-free operation. The dazzle-free reflection mirror comprises a dazzle-free portion to effectuate the dazzle-free operation at a lower part of the mirror surface and a non-dazzle-free portion not to effectuate the dazzle-free operation at the rest part of the mirror surface. The dazzle-free portion shields light from following-vehicle headlights at night so that the driver feels no glaring. The non-dazzle-free portion clearly images a rear view so that the driver can see an appearance of the following vehicle.

摘要： A control apparatus for a reflection mirror of a vehicle is disclosed. The control apparatus is provided with a rear light sensor, an exterior light sensor and a circuit for driving the reflection mirror into a dazzle-free condition when it is detected by the sensors that an intensive rear light is incident from the rear of the vehicle and the exterior of the vehicle is dark. The control apparatus is further provided with a delay circuit which delays driving the reflection mirror into the dazzle-free condition for a predetermined interval of time after the exterior light sensor detects that the exterior of the vehicle is dark. The exterior light sensor may be a switching circuit which switches on and off front light bulbs of the vehicle. The control apparatus is still further provided with a delay circuit which keeps the dazzle-free condition for a predetermined interval of time even after the rear light sensor detects that the rear of the vehicle is dark.

摘要： A liquid crystal type dazzle-free reflection mirror arrangement which changes reflectivity of the incident light by way of changing the transmittivity of the incident light through a liquid crystal provided within a frame body is disclosed. A semitransparent mirror is positioned behind the liquid crystal and a photo sensor is positioned behind the semitransparent mirror. When the photo sensor detects that the intensity of the incident light passing through the semitransparent mirror, an alternating current electric field is applied to the liquid crystal which responsively decreases the transmittivity of the incident light. A heater for heating the liquid crystal is activated when a door of an automobile is opened and the temperature of the liquid crystal is low.
