Νέα LED φλας για το Audi A8 Facelift

19:41 14/8/2013 - Πηγή: AutoBlog

Η Audi στην έκθεση της Φρανκφούρτης θα παρουσιάσει το ανανεωμένο Α8 το οποίο θα γίνει το πρώτο μοντέλο που θα φορά τα ολοκαίνουργια Audi Matrix LED φωτιστικά σώματα.

Αυτά συνδυάζονται με νέα LED φλας τα οποία αποτελούνται από 18

LED διόδους μπροστά και 24 LED πίσω, τα οποία ενεργοποιούνται διαδοχικά κατά 20 ms με κατεύθυνση από μέσα προς τα έξω. Μετά από 150 ms όλοι οι διόδοι είναι αναμένοι, και για ακόμη 250 ms φωτίζουν με πλήρη ένταση. Στη συνέχεια τα φλας σβήνουν.

Highly effective: new turn signal light in the Audi A8

Indicator LEDs light up sequentially in the turning directionAdvanced turn signal light is a component of the Audi Matrix LED headlight

In the new Audi A8, the turn signal light consists of lighting elements that illuminate in a defined sequence; this makes it easier for others to perceive the driver’s turning intentions, even under difficult conditions.

In the new Audi A8, the turn signal lights will now indicate the turning direction in an innovative way, which has the potential to significantly enhance traffic safety. That is because the lights provide a visual signal that can be clearly and quickly perceived, even at long distances and in poor visibility.

Each of the enhanced headlights contains18 light-emitting diodes arranged in a strip that is subdivided into seven blocks. Each tail light contains 24 LEDs in eight segments, which are used to dynamically indicate the turning direction. During flashing, the blocks are sequentially activated at 20 millisecond intervals, from the inside outwards in the desired turning direction. After 150 milliseconds, all segments are bright; for another 250 milliseconds they illuminate with full intensity. Afterwards, the turn signals go dark before repeating the lighting sequence.

Considering their capabilities, the Audi Matrix LED headlights can be regarded as a cutting-edge innovation. In each headlight, 25 light-emitting diodes generate a highly variable high-beam light. When the on-board camera detects other vehicles ahead, the Audi Matrix LED headlights mask the relevant sections of the high-beam by dimming or shutting off individual diodes. Very bright illumination is preserved in the remaining zones.

The Audi Matrix LED headlights also feature navigation-based cornering lights and, in cooperation with the night vision assistant, a marker light that warns the driver of pedestrians in the dark and which also alerts the pedestrians.

Audi will be presenting the upgraded A8 in September at the IAA International Motor Show in Frankfurt.
