More road safety at night. Mercedes-Benz offers a preview of what the future holds – LED technology today, tomorrow and in the more distant future.

LED technology: when night turns into day.

Mercedes-Benz offers a preview of what the future holds.

  • LED technology: when night turns into day.

  • The pursuit of perfection.

    Outstanding light technology form part of a continuing tradition at Mercedes-Benz: over 120 years of headlamp technology stand for ongoing progress in the interests of enhanced road safety and the introduction of innovations to benefit the company’s customers and other road users.

    “Enabling ideal visibility in all driving situations without dazzling other road users has always been our credo in developing new light systems,” observes Uwe Kostanzer, head of light systems development at Mercedes-Benz. “We are pursuing the further development of LED technology to this end.”

    When it comes to the number of pixels, the same is true of LED headlamps as of a digital camera: the more the better. The higher the number of individually controllable pixels, the more finely the light can be controlled and adapted to different conditions. A high resolution enables an increase in both precision and brilliance.

    In 2014 Mercedes-Benz introduced the innovative MULTIBEAM LED headlamps in the CLS-Class.

    MULTIBEAM LED – a milestone.

    In 2014 Mercedes-Benz introduced the innovative MULTIBEAM LED headlamps in the CLS-Class. These are fitted with 24 individual high-performance LEDs. Each one of these LEDs can be individually electronically controlled. 'Gridding' the light in this way allows the light distribution from the right and left headlamps to be controlled entirely separately and adapted to the traffic conditions with a high level of dynamism.

    This enables the individual areas of the road surface to be illuminated in a very specific manner. The headlamp control technology combines the gridded light source with the proven mechanical technology of the LED Intelligent Light System, and the high-performance LEDs provide for a range of 485 metres.

    Safety is of paramount concern.

    The added safety provided by the MULTIBEAM LED technology becomes apparent above all in real traffic situations: in contrast to static high beam systems, some of which have long ranges, MULTIBEAM LED also supports the driver when there are other vehicles in the field illuminated by the headlamps. By means of totally independent control of the individual LEDs of the gridded light source, the MULTIBEAM LED headlamp is able to mask other road users out of its light distribution in a fraction of a second, thereby enabling high beam to remain on. This assures the driver of the best possible light performance at all times, without dazzling other road users.

    At Mercedes-Benz road safety is paramount.

    In the near future, Mercedes-Benz will be incorporating an additional HIGH RANGE LED high beam into its LED headlamps. This additional high beam employs state-of-the-art high-performance LEDs to provide high beam ranges of over 600 metres in driving situations without any oncoming traffic or vehicles ahead. It also enables Mercedes-Benz to exploit the legally permissible level of illumination in Europe virtually to the full.

    Mercedes-Benz will soon be presenting MULTIBEAM LED headlamps with a gridded light source containing 84 LEDs.

    Tomorrow’s LED technology.

    Mercedes-Benz will soon be presenting MULTIBEAM LED headlamps with a gridded light source containing 84 LEDs, enabling even higher resolution of the light output. This will afford other road users even better protection from dazzling, while improving illumination of the road ahead for the driver.

    As a result of the absolutely freely configurable light distribution, it is possible for the first time to implement all high- and low-beam functions of the Intelligent Light System in entirely digital mode and without any mechanical actuators. This will make a wealth of new, adaptive light functions possible which will render night-time driving yet safer for both the driver and other road users.

    In the medium term 1024 individually controllable pixels per LED chip will enable a further improvement in night-time visibility, resulting in further enhanced safety.

    Taking a look into the near future.

    This technology is set to advance at a rapid pace: in the medium term 1024 individually controllable pixels per LED chip will enable a further improvement in night-time visibility, resulting in further enhanced safety. The partners Infineon, Osram, Fraunhofer Gesellschaft IZM, Hella and Daimler have just achieved a breakthrough in the 'μAFS' research project in the form of a new type of LED chip with an extremely fine structure.

    Monolithically structured pixel LED semiconductor layers are built up on a silicon substrate which, via the integration of circuit parts, allows the selective control of more than 1024 individually addressable pixels per LED chip. This LED technology is to be installed and tested in a Mercedes-Benz experimental vehicle in 2015 for the first time.
