In the new version of the Audi A8 light emitting diodes from OSRAM Opto Semiconductors are responsible for the dipped and full beams as well as for other specific lighting functions. Apart from their efficiency, an excellent argument for LEDs is their long life, which exceeds that of the vehicle. Plus, with light similar to daylight they improve motorists’ safety.

Striking features of Audi’s current vehicles are the LED daytime running lights installed in the headlamps. In the new top-of-the-range A8 OSRAM LEDs now take on further lighting functions in the headlamps – not only dipped and full beams are based on the energy-saving.

The OSTAR headlamp LEDs fitted in the A8 illuminate the road surface with perfect definition, without glare, and they produce a light similar to daylight, which enhances perceptions of contrast. In the peripheral field of vision especially, i.e. where pedestrians, animals or poorly lit vehicles may suddenly appear at night, it is easier to recognize objects with white LED light. But even potholes, obstructions and worn road markings are much more visible thanks to the attributes of LED lighting. Essentially, this technology has the potential to prevent numerous accidents caused at night.

An innovative conversion process provides a seamless white colour impression at maximum brightness levels. Typical light values achieved for each LED chip are 160lm at 700mA. Depending on the variant and operating current, values between 125lm and 1100lm are achievable. With its scalable brightness, the OSTAR Headlamp is perfectly suited to all headlamp functions such as full and dipped beams, cornering lights, fog-lamps and even for use in daytime running lights.
