The automobile industry is evolving every single minute. Every car manufacturer is coming up with new and quirky features now and to establish dominance in the market. Some of them are just bells and whistles but some are actually innovative and today we are to explain one of the most innovative and effective features, day and night auto-dimming IRVM. So get ready to explore the complete guide about auto-dimming IRVM.
What is auto-dimming IRVM?
Auto-dimming mirrors are the special type of rearview mirrors that have the capability to dim the light reflecting from their surface. These mirrors reduce the glare of light coming from trailing vehicles significantly thereby reducing driver fatigue.
Naturally, such mirrors prove to be very useful while driving on heavy traffic roads at night. Internal, as well as external rearview mirrors fitted on a vehicle, can be of this type.
How long have they been around?
You’ll be surprised to know but auto-dimming IRVM were invented long back in the 1950s! Chrysler Corporation was the first company to feature auto-dimming IRVM in 1959. But the ball really started rolling in the 1980s when several luxury manufactures started offering this useful feature. Today almost every car above 7 lakhs has auto-dimming IRVM and GENTEX is the leading manufacturer.
How do they work?
- The control unit is the core of the IRVM. It gets signals from the sensors. And afterwards, it settles on how to manage the glare.
- There is a conductive layer between the mirror and the glass comprising of three sub-layers electrochromic, electrolyte, and particle stockpiling.
- An encompassing sensor that advises the control unit to begin its working when the surrounding light is low. The body of the mirror and The glare sensor estimates the light power that falls on the mirror.
- When the sensors comprehend, it informs the control unit to carry on likewise. The light could be fighting against eminent loss in the mirror or from the front.
- The sensors at that point consequently diminish and obscure the mirror or light and light it up.
- At the point when the light falling on the sensor from behind is more than the light rolling in from the front, the electronic framework darkens the mirror.
What is the technology behind this?
The mirror surface is equipped with electrolytes or particles comprising of uniform precious stones, very much like a cell phone screen containing an LCD. At the point when the precious stones get a voltage, they get organized at a specific point, which thus decides the measure of light that can get reflected. The voltage decides to the degree the mirror darkens out. Phew! Science
How to know if your car has auto-dimming IRVM?
The easiest way to check this is that when there is a car behind yours with its headlamps on, cover the front sensor-ideally the mirror should get brighter and if you take your hand away from it, the mirror should dim again.
Day and night IRVM
These are also very effective and has much less tediousness to them. Every new car has day and night IRVM. They have a small manual switch at the bottom of the mirror. During the night, when the car behind you has its headlamps on, just flip the switch. The mirror changes its position and avoids the glare to ensure a comfortable drive for you and during daytime it can again be switched to its normal position. Hassle-free!
