The brand with the four rings has since acquired a technological edge putting it years ahead of the competition, and is a key driver of this innovation. Crucial for the exterior design: Not only during the day but also at night, all Audi models are recognisable at a glance thanks to LED daytime running lights. And each Audi has its own personality: The sweeping light strip on the Audi A4 exudes elegance. And that of the Audi R8 radiates strength and dominance: Its headlights were designed and constructed entirely on the basis of energy-efficient and environmentally friendly LED technology.
A tiny dot on your finger, as minute as a grain of sand. This speck of material uses electrical energy to generate more white light than any conventional light source in the world. A light-emitting diode, or LED, is a semiconductor device – just a square millimetre in size – which boasts a remarkable physical property. It can convert electrical energy directly into light and is unbeatably efficient when it comes to energy consumption. Today’s xenon and LED headlights are four times more energy-efficient than halogen headlights. And by 2018, LED technology should be about eight times more efficient than halogen light. In addition, LEDs excel due to their practically indefinite service life and react up to ten times more quickly than traditional incandescent bulbs.
