How Does a Electro-chromatic Auto Dimming Mirror Work?

What Exactly Are Electro-Chromatic Mirrors Systems? 

These mirrors utilize a combo of both optoelectric sensors along with complex electronics, including micro-controllers, sensors, and even circuit boards to monitor the ambient light and the overall intensity of the light that shines on the mirror itself. Once the indicated sensors observe the glare, the mirror darkens’ surface to give the driver better visibility.

This technology is typically used in both the side mirrors and the vehicle’s rearview mirror. It essentially saves the driver from having to manually flip the mirrors if you get distracted by glare, which ultimately enhances the driver’s safety and everyone on the road.

Electro Chromatic Mirrors And Their Working Operation

This mirror is typically reserved for higher-end and more expensive vehicles. It is made up of two different lenses that feature an electrochromic gel in the middle. The inside portion of the lenses is fully coated with a conductive layer transparent coating, and the furthest lens has a reflective coating.

The gel gets darker when charged with electricity. Once it doesn’t detect glare any longer, it turns back clear. The mirror features a forward-facing sensor that measures the total amount of ambient light on the outside and a sensor facing the rear that detects the level of ambient darkness and glare. When the ambient light outside increases, the current amount decreases until the point where the gel turns clear once again.

A Rear-View Mirror With Electro Chromatic Reflection?

Color change occurs when an electrical current passes to a substance, referred to as electro chromism. Change can be undone. For nighttime driving, an electroactive rear-view mirror reduces glare by dimming automatically when it detects light coming from behind the vehicle. The mirror employs light sensors and an unique gel that changes color whenever an electric charge causes this to either lose or gain electrons, and therefore, it is electrically driven.
