Audi extends the lead with high-resolution Matrix Laser technology

Posted on 28. Apr, 2015 by in Volkswagen Canada

Audi is serve fluctuating a lead in automotive lighting technology. In a sponsored plan “intelligent laser light for compress and high-resolution adaptive headlights” (iLaS), a code with a 4 rings is operative on a headlights of a destiny with partners from attention and science. Matrix Laser record and a high fortitude will make alley enlightenment even some-more stretchable and rarely versatile – in all situations.

Matrix Laser record is formed on a LaserSpot for high‑beam lamps, that Audi initial introduced to prolongation in a Audi R8 LMX*. For a initial time, splendid lasers are creation it probable to confederate projector record in a compress and absolute headlight.

The new record operates with a fast relocating micro-mirror, that redirects a laser beam. At low car speeds, a light is distributed to a incomparable projection area, and a highway is bright with a really far-reaching range. At high speeds, a orifice angle is smaller, and a power and operation of a light are increasing significantly. This is generally fitting in highway driving. In addition, a light can be distributed precisely. This means that a liughtness of opposite lighting zones can be sundry by determining a enlightenment dwell times in a specific zones.

Also new is intelligent and lightning-fast activation and deactivation of a laser diodes in propinquity to a counterpart position. This creates a broadening or squeezing of a radiant lamp energetic and rarely variable. As with today’s Matrix LED headlights from Audi, a highway is always brightly illuminated though causing glisten to other participants in traffic. The essential disproportion is that Matrix Laser record offers even finer energetic fortitude and therefore a aloft grade of utilization, that leads to larger reserve in highway traffic.

In a new technology, blue laser diodes from OSRAM illuminate their light, that has a wavelength of 450 nanometers, onto a fast relocating counterpart that is 3 millimeters in size. This counterpart redirects a blue laser light to a converter, that translates it to white light and projects it onto a road. The counterpart used for this, that comes from a Bosch company, is a micro-optical complement that facilities electro-mechanical control and is formed on silicon technology. It is really stout and exhibits really prolonged life. Such components are also used for accelerometers and control units for electronic fortitude control.

For many years now, Audi has been a personality in automotive lighting technology. Some of a brand’s pivotal innovations:

2003: Audi A8* with adaptive light

2004: Audi A8 W12* with LED daytime using lights

2008: Audi R8* with all‑LED headlights

2010: Audi A8 in that a headlights are networked with a navigation data

2012: Audi R8 with energetic spin vigilance lights

2013: Audi A8 with Matrix LED headlights

2014: Audi R8 LMX with LaserSpot for a high‑beam lamps

In a horizon of a three-year “iLaS” project, Audi is operative closely with a partners Bosch, Osram and a Lichttechnischen Institut (LTI; “Lighting Technology Institute”) of a Karlsruhe Institute for Technology (KIT). The plan is sponsored by a German Federal Ministry for Education and Research.

Fuel expenditure of a models named above:

Audi R8 LMX:

Combined fuel expenditure in l/100 km: 12.9** (18.2 US mpg);

Combined CO2 emissions in g/km: 299** (481.2 g/mi)

Audi A8:

Combined fuel expenditure in l/100 km: 11.3 – 5.9** (20.8 – 39.9 US mpg);

Combined CO2 emissions in g/km: 264 – 144** (424.9 – 231.7 g/mi)

Audi A8 W12:

Combined fuel expenditure in l/100 km: 11.3** (20.8 US mpg);

Combined CO2 emissions in g/km: 264** (424.9 g/mi)

Audi R8:

Combined fuel expenditure in l/100 km: 14.9 – 12.4** (15.8 – 19.0 US mpg);

Combined CO2 emissions in g/km: 349 – 289** (561.7 – 465.1 g/mi)

**The fuel expenditure and a CO2 emissions of a car change due to a choice of wheels and tires. They not usually count on a fit function of a fuel by a vehicle, though are also shabby by pushing function and other non-technical factors.
