Multibeam / Matrix LED Headlights

[DaveBerlin]

As recently the question of the QQ LED Headlights and comparisons were made I thought that some of you might be interested in what is coming from Germany. Attached is some info' on the Mercedes / Audi / BMW Systems with videos - Take a look Dave

Mercedes-Benz introduced the face lifted CLS Class complete
with the firm's new Multibeam LED Headlights with 24 high-performance
LEDs on each headlight unit. This allowed for full-time operation of the
high-beam function without dazzling other road users by individually
controlling certain parts of the beam, in a manner similar to Audi's Matrix LED Headlights. Now the company has outdone
itself with a showcase of a working prototype headlight, containing a
staggering 84 LEDs. Mercedes claims that the higher resolution of the light
beam will better shield other motorists from high-beam dazzle, while providing
increased forward illumination for the driver. Adding another couple of tiers
of LEDs also allows the digital incorporation of all low- and high-beam
functions, negating the need for mechanical actuators to control the headlight
unit. This will also enable the addition of new adaptive lighting functions,
and should also reduce complexity and maintenance.

Mercedes is now working on a
new LED chip with up to 1,024 individually controllable pixels, making for an
even higher-resolution light beam. The company plans to install and test such a
technology on an experimental vehicle next year, with the goal of
production in the near future. Also planned is an additional High Range LED
high-beam, which will be able to project light at a distance of over 600 m.

Unlike the Laser Powered
Headlights currently employed by BMW and Audi, Mercedes claims such technology will be able to
achieve this performance while keeping costs and complexity at a more
manageable level, as well as fully utilising the maximum permissible level of
illumination in Europe.

Audi's
Matrix LED headlamps activate,
deactivate or dim automatically at night, according to the situation. The technology involves numerous individual
diodes working in conjunction with lenses or reflectors connected in series. Each
headlamp contains 25 high-beam LEDs, arranged in groups of five per
reflector. When an oncoming vehicle is
detected, relevant sections of the high beam are dipped, so as not to dazzle
its driver. The closer the vehicle gets, the more LEDs are deactivated or
dimmed, while areas around the vehicle continue to be illuminated by the high
beam. With auto headlamps activated and high-beam on, the system operates
from 30 km/h on highways and from 60 km/h on city streets.

Have to say Mercedes lights are excellent, so far ive not driven a better well lit car.Mind you they got the budget to realy push the boat out

LED technology is pretty amazing. I have just fitted 5 x downlighters in my kitchen running off 240v transformed down to 24v each uses 3w of power but emits the equivalent of 75w each at the bulb output. These were bought from Hera in Germany and the range of LED's they make is unbelievable, even self adhesive strip ones in lengths up to 2 metres.
