Headlights technology

What is this advance front light system?

Today we want to talk about what this advance front light system is.. Let's discuss about this simply..

One thing we know is that we have the ability to operate our main lamps (front lights) under two situations.

When traveling on the road at night, high beam is used to illuminate the road ahead (for a long distance) and
dim (Depth) beam is also used to illuminate the road ahead for a short distance.      
But under these two circumstances, when we are driving on the road, in some cases, the cars and pedestrians coming in front of us may have some inconveniences for them.

So the first product made by car manufacturers for this is to connect Automatic High Beam System - AHB to these cars.

Here, a Front Recognizer Camera connected in the upper center of the Windscreen detects the light beam of the cars coming in front and thus recognizes that a car is coming in front and changes our headlights accordingly. If the high beam is running at the same time, the low beam will be automatically set and the high beam will be activated again when the car passes. 


But car manufacturers are moving further in that technology and creating Adaptive Frond Light system. This has been added to cars by different car manufacturers using their own technologies under different names.  • Audi – Matrix LED Light System
    

• Mercedes Benz – Multibeam Technology
• BMW – Adaptive Headlight
• Toyota – Adaptive Front Light System

Here we hope to discuss a little deeper about the multibeam technology used in cars. There is a certain idea in the word multi-ground that means multiple beams of light. The headlamp used in these cars has the ability to illuminate every place ahead of the road with several beams. There, the light emitting diodes that emit a very intense light, using the LED bulbs that we know very well, make a superior, easy-to-drive, light beam fall to every place on the road. 

The function of this system is to limit the light emitted by each light emitting diode installed in this headlight to each point on the road. The advanced technology camera mounted on the windshield has the ability to detect all things like people and cars moving in front of the car.  After detecting those parts, the light emitting diode related to that place is automatically turned off and light is prevented from falling on that place.

In addition to this, another special function of this system is to direct the lighting system of the car in the direction of the turn according to the data obtained by the steering angle when the car turns.  This system allows the driver to see the road better.

Let's see what are the components of this system -

Different car manufacturers have developed these complex control circuits using their own different technologies and let's examine their functionality.
When the car is traveling at night, if the car's headlights are on, the camera installed on the front of the car detects the headlight status of the cars coming in front, the pedestrians on the road, and the information is given to the front light. system control, and the front light system controls accordingly. The bulbs related to the place are turned off so that the visitor can walk on the road without any hindrance.
Here a large number of LEDs are installed in a circuit and its control unit is also installed in it.

If there is any fault in any part of the system, the fault will be shown to the driver through fault indication.

This describes the general functionality of this system used in cars and this may vary slightly depending on the technology used in certain car models.
