Osram Opto Semiconductors GmbH of Regensburg, Germany says its Oslon Compact PL LEDs for adaptive front lighting have been used for the first time by car maker Audi in its new A8 flagship model. In addition, the Oslon Black Flat S (in its three-chip version) provides an extended beam range. Also, Osram’s tried and tested Topled is used in the car’s daytime running lights (DRLs).

The innovative feature of the Audi A8’s HD matrix headlights is that, for the first time, the Oslon Compact PL LEDs are arranged in two lines. Other road users are hence masked out even more precisely by the light beam and are not dazzled. The Oslon Compact PL has an electrically insulated thermal contact. By using appropriate PCB technologies the thermal connection can be significantly improved, yielding higher luminous flux. At the same time, notchless chip technology allows the optical systems to be more efficient. After market launch at the end of 2017, it is being used for the first time in the new Audi A8 as adaptive high beam and low beam.
The Oslon Black Flat S family, which also features notchless chip technology and is celebrating its premiere, has now been installed in the Audi A8 for the first time in its three-chip version. The individually controllable chips allow the light beam to be adjusted to the environment (e.g. in city traffic or on the highway), increasing visual comfort.
“The lights now adapt even more precisely to complex traffic situations,” says Peter Knittl, Osram Opto’s general manager Automotive. “The surrounding area is illuminated in the best possible way without dazzling other road users,” he adds.
