Headlights of modern cars are not just a source of light, consisting of the body with glass and a bulb, but a high-tech device with an electronic control unit, capable of literally thinking and directing the light flux independently depending on the situation and road conditions. But it was not always like this and the evolution of car h1 lampe has passed a long way of development.
Let's start with the very first cars, which are even called differently - self-running carriages. These were Carl Benz's vehicles, and they were blind. The first Renault models were also devoid of any lighting elements. After a while, they tried to install kerosene lamps on the cars, which did not take root because they gave too little light. In 1985, a French designer and businessman Louis Bleriot began producing acetylene floodlights for steam locomotives, and they transferred to cars at the end of the 19th century.
Electric lights began to be used in 1912, the first car was the American Cadillac Model Thirty. In 1918, the German engineers from Bosch have created a lamp with two filament filament, which allowed to separate the light at low and high beam. Car manufacturers used the invention of Bosch until the mid-1950s.
In the fifties, another breakthrough took place - the technology of asymmetric light appeared, it allowed diverting light from the oncoming lane. The pioneer was the French car Cibie, later this system began to be equipped all over the world. The next breakthrough came in 1962, when German Hella showed the world its invention - halogen headlights.
At the same time headlights began to change their shape. Thus, in 1962, the first car in the world with headlights not round, it was Citroen Ami, which surprised the world with rectangular "eyes". Five years later, the French manufacturer amazed everyone again, having shown rotary headlights on the DS model, which changed direction by turning the steering wheel.
Until the nineties, cars were equipped with incandescent headlights. In 1991, the first gas discharge lamps, in which injected xenon gas shines, appeared. For a long time the world did not enjoy xenon, as a year later there appeared a new invention - LEDs, which consume less energy, shine better and are cheaper to produce. And that's not all: manufacturers continue to experiment with light.
The latest generation of BMW with the Eye-Tracking system installed. Located in the cabin, cameras follow the eyes of the driver, and the headlights shine in the direction where the eyes look. Mercedes is currently working on the laser headlights, which are able to "beat" up to 600 meters ahead. Meanwhile, engineers from the German automobile giant say that diode technology has not yet exhausted itself.
