driving at night is the biggest security risk of sight problems, not only because of the bad dark light, and each car has always been the headlights also have an impact on driving safety; caught misbehaving driver behind the long-term open with high beam , interior mirror reflecting light directly into the eyes with intense direct impact on traffic safety, in order to reduce the risk of the occurrence of auto-dimming mirror function emerged. Usually automatic dimming rearview mirror is divided into inner and outer dimming mirror dimming.
1. The automatically dimming rearview mirror
the current mirror dimming in two forms, one for the hand, by suppressing glare optics, this rear-view together using a double mirror the mirror reflectivity, when the driver that the reflected light is too strong glare, the mirror angle can be adjusted manually movable lever mixing the mirror angle offset, at this time of the small reflection mirror, It can weaken the strength of natural light.
“Manual dimming rearview mirror principle.”
After the “electronic dimming view mirror effect “
arranged on the vehicle is equipped with a high auto-dimming mirror, which mirror behind the mirror of the photodiode is mounted, a control circuit applying a voltage to the light sensing diode mirror ionosphere on applied voltage under the lens will darken to achieve the purpose of blinding.

2. Auto-dimming outside mirrors
real-time monitoring of the rear light intensity sensor, and automatically adjust the mirror reflection effect. Night rear of the vehicle will become harsh lights dim and soft; backward when no glare light, mirror reflection effect instantly returned to normal to ensure the stable and good rearward visibility, improve night driving safety.
