Letter from Frankfurt: LEDs at the Motor Show
LEDs were much in evidence at the Frankfurt Motor Show, both on the cars and also on the booth displays.
Very few companies specifically mentioned LEDs in their exhibits or literature. Many exhibits focused on energy efficiency and alternative drive technologies – for example BMW's Efficient Dynamics program and its Active Hybrid and Clean Energy hydrogen-combustion developments.
Which is not to say there weren't any LEDs at the show – in fact quite the opposite.

Barco had a number of other installations (see press release) and other companies such as Element Labs, G-LEC and Hibino were also represented.
On the cars themselves, many manufacturers showed concept vehicles with all-LED lighting, including low- and full-beam headlamps.

Audi now has five models that make use of white LEDs, in different configurations, for daytime running lights (DRLs) on the front of the vehicle. These were also seen on vehicles from Porsche and Aston Martin, as well as the luxury VW Phaeton.
Going one step further, Lexus is set to become the first company to sell in the European market a model with LEDs for the low-beam headlamps. The LS hybrid also has a more conventional xenon lamp for the high-beam function. A Cadillac model will be available by the end of the year that uses a similar (LED + xenon) combination.

The November/December issue of LEDs Magazine will feature a comprehensive report on the LED displays in Frankfurt, and will discuss progress in LEDs for automotive headlamps.
