The lighting technology vehicles has improved in recent years significantly. For decades, incandescent lights of varying quality were the only ones that could be accessed. Then came the headlights of car halogen, that did not stop being a variety of incandescent lights, but more powerful and durable. In the nineties, xenon headlights began to appear, a technology that is still very present today. In 1991 the company Osram was first put in a vehicle, the BMW 7 Series, this type of lighting in low beam and many premium brands signed up to the car. From 2001 were incorporated into many vehicles the road, which became known as bi-xenon. Let’s talk about Cars go without bulbs.


Comes LED system

The LEDs (Light-Emitting Diode or light emitting diodes), born in 1962 in a very rudimentary way, are now the latest in lighting. They have been added gradually to cars, first inside because it does not need replacing, and from 2007 on the outside, thanks to its perfect application for permanent lights. In principle all advantages, because they have much lower power than conventional ones last about 100,000 hours (about 20 years at least), remain forever the same intensity are easily target able automatically and follow the road and allow you to apply many possibilities of “smart” technology that benefit both the driver and other users, particularly at night on roads with poor or no lighting.

Mercedes S Class, the car without bulbs

Now, more than a century after the cars incorporate electric lighting, Mercedes has introduced the first vehicle that does not have a single bulb filament. Obviously it has done with his flagship, the S class, the epitome of the German mark. The Mercedes S Class also completely without bulbs we have always known, lighting introduces new features such as a variable intensity brake to avoid disturbing other drivers or both systems improved nighttime visibility: road lights Plus automatic and Night View Assist Plus. The result is a significant increase in traffic safety. Speaking of numbers, in some finishes the Class S has almost 500 LEDs that illuminate the road and around the vehicle, including interior and trunk. The headlights have up to 56 LEDs per headlamp, optical rear 35 each, and the interior have about 300 LED lights.

Laser lighting, later this year

When even this type of LED lighting just been incorporated into the market, advertised and year-end technology that exceeds: laser. Will achieve a viewing distance of 600 meters and is more energy efficient because the diodes are smaller. Such scope should have its limits, so a camera system to guide the light emitted without losing visual field, but considering cars circulating circulating front and back when we overtake be used. Laser technology has already been announced by the concept GLA Mercedes and Audi R8 with already has a point, although it will be BMW with spectacular new hybrid i8 which first goes on sale with these headlights.
