Brief introduction to the use of anti-glare rearview mirror
The anti-glare rearview mirror consists of a special mirror, two photodiodes and an electronic regulator. The electronic regulator receives the front and rear optical signals from the photodiode and is installed under the front windshield of the carriage. Comprise a manual anti-glare rearview mirror and an automatic anti-glare rearview mirror.
How to use anti-glare rearview mirror: principle
Automatic: the anti-glare rearview mirror in the car has a constantly changing anti-glare function when it is illuminated by the headlights of the car behind it. The anti-glare rearview mirror in the car consists of a special mirror, two photodiodes and an electronic regulator. If the illumination lamp shines on the rearview mirror, the electronic regulator obtains the front light or backlight signal from the photodiode. For example, when the backlight is larger than the front light, the electronic regulator will output a voltage to the conductive layer. The voltage on the conductive layer changes the color of the electrohydraulic fluid. The higher the voltage, the darker the electro-hydraulic color. At this time, even if strong light shines on the rearview mirror, it is reflected to the driver's eyes by the anti-glare rearview mirror in the car, but it is not dazzling. Although the automatic anti-glare rearview mirror can prevent glare, when reversing out of the garage, because the light behind the car is strong and the light in front of the car is weak, if the rearview mirror darkens, it is not conducive to seeing the situation behind the car when reversing, so the car is designed to automatically cancel the anti-glare function when reversing, or it can be manually cancelled by switching.
Manual: The principle of manual anti-glare is not difficult to understand. It is not a flat mirror with similar thickness, but a mirror with an angle of about 10. A wedge-shaped mirror with upper and lower angles. Generally speaking, the thickness of the upper part of the material needs to be thicker than the lower part. Under normal circumstances, the light will be refracted by the mirror coating on the back and reflected into our eyes, which is also the principle of ordinary flat mirror. However, after anti-glare is turned, the whole mirror will be adjusted upwards by 10 degrees. Up and down (similar to the angle of the mirror segment), what we observe at this time is actually the translucent coating of the rearview mirror, which has a low refractive index to the light, thus playing an anti-glare effect.
How to use the anti-glare rearview mirror: how to open it
There is a little black thing under the rearview mirror. Open it.
Anti-glare rearview mirror can shorten the possibility of being flashed by strong light at work. What we need to know is that strong light will affect our blindness for a short time, which is very dangerous.
After reading the profile of the car editor, my friends all know how to use this anti-glare rearview mirror. The car editor also briefly introduced the possibility that the anti-glare rearview mirror can shorten our eyes when we work. We still have to pay attention. Ok, let's briefly introduce the use of anti-glare rearview mirror to friends.
