Audi is going to release a new 2014 Audi A8 by the end of the year and Audi has announced that it will arrive with Audi's new Matrix LED headlights. Audi Matrix LED technology splits up the LED high-beam headlights into numerous individual, small diodes working in conjunction with lenses or reflectors connected in series. Managed by a responsive control unit, they are activated and deactivated or dimmed individually according to the situation. This means they always supply high-precision illumination and achieve the maximum possible light yield without needing a pivoting mechanism.
In the new Audi A8 each headlight comprises 25 high-beam light-emitting diodes, arranged in groups of five per reflector. When the light switch is set to "automatic" and the high-beam headlights are on, the system is activated from 18 mph on highways and from 37 mph on city streets. The Audi Matrix LED headlights produce a quality of light with a special crystalline sheen.
As soon the camera in the A8 detects oncoming vehicles, the Audi Matrix LED headlights dip the relevant sections of the high-beam headlights. The system blanks out light that would shine directly onto oncoming vehicles, but continues to cast the high beams with full power on all other zones between and beside them. The closer an approaching vehicle gets, the more LEDs are deactivated or dimmed. When there is no more oncoming traffic, the high-beam headlights then resume full power, including the sections that had previously been off.
Although Audi is calling the 2014 Audi A8 "new" it's expected that it will be more of a refresh than an all-new model.
