While driving, make sure that you clearly see the objects and people on the road ahead. It might be an issue when you’re driving at night, or in whether such foggy, snowy or rainy. In such stations, visibility is poor, and you’re likely to face difficulty in driving and in the worst cases fatalities.
For example, when it’s raining, driving is hard it looks hazy because the head lights reflects back the rain drops. To overcome this issue automakers developed a system called smart head lighting system installing this system you feel like the rain drops vanished. The smart head lighting system uses the digital projector to illuminate the rain drops. Let as discuss how it works.
How the smart head lighting system works
The smart head lighting system consist of a camera, projector and beam splitter.
When you’re driving in heavy rain or snow fall, the camera takes the picture of the rain and it is sent to the processor. The processor analyzes where the drop lets are and sends the information to the projector with in split seconds.
The projector uses beam splitter to dis- illuminate the rain drops. The processor informs where the droplets and sends the information to projector.
The projector blocks the part of the grid where the rain is falling, Since the beam of ray doesn’t fall on the rain drop. The droplets do not reflect back creating blur.
Due to this system you can clearly see objects and people while heavy rainfall or snowfall.
In some vehicles, this system is already installed, this is one of the recent developments in features in automobile. Currently this technology is available in high-end cars and in the years to come, all vehicles are likely to feature it.
How fast will the system need to be for use in vehicles
The micro processor simulates the system operating approximately at 950 Hz, with a total system time interval of 1.5 ms and exposure time of 1 ms with an accuracy of 90% light put on during a heavy rain fall (25 mm) on a vehicle traveling at 28 km/hr.
Advantages of smart head lighting system
- It increases the visibility during heavy rain or snowfall.
- Research shows that compared to conventional head lighting system, this technology decreases fatalities by 25%.
These are some of the advantages of smart head lighting system hope you enjoyed reading.
