OSRAM’s LED technology contributes to the energy efficiency of Volkswagen’s L1 concept car presented at the Frankfurt International Motor Show (IAA). The vehicle, which according to Volkswagen can go into production in 2013, has headlights that are equipped with new OSRAM Joule JFL2 LED systems and matching reflectors. The LED modules take care of the dipped and main beam functions and consume far less energy than conventional headlamps. Joule JFL2 LED modules will be introduced in production in early 2010 and can then be included in new vehicle models easily and across multiple platforms.

One key to the unparalleled energy-efficiency of Volkswagen’s L1 are OSRAM’s highly efficient Joule JFL2 LED modules, which are used in the front headlights. What is special about them is that the dimmable LED light sources are responsible for the important dipped and main beam functions. Each of the only five centimetre high headlights requires a total of three modules. Two provide the ECEcompliant (Economic Commission for Europe) main light and one the high beam. Apart from the high performance diodes, this is made possible by the reflectors Volkswagen has developed, which shed an ideal light on the road and are therefore the perfect complement to the JFL2 LED modules.
 
With a power input of only 19 watts per dipped beam, the one-litre car’s lighting is far more energy efficient today than conventional headlight solutions, in which mostly halogen lamps with 55 watts are used. Even Xenon lamps at only 35 watts of input use 20% more energy on dipped lights (95% of nighttime driving) than two Joule JFL2 LED modules.


Joule JFL2 LED modules by OSRAM can be incorporated platform-independently in vehicle headlights.

Volkswagen’s L1 comes with economical OSRAM Joule JFL2 LED systems in the main headlights.

With a power input of only 19 watts per dipped light, the L1’s lighting is far more energy-efficient today than conventional headlamp solutions.
