In 2008 the first full LED (LED = Light Emitting Diode) headlamp will arrive to the worlds markets, providing all lighting functions with semiconductor based light emitting devices, LED. The first Full LED headlamp differs in style and technology from other headlamps. Target was to find a face that fulfils the demands of the stylists and also gives the possibility to be assembled, to fulfill customer specs and legal requirements. Fulfilling this, the development showed various intermediate steps. As LED is still a evolving technology, mature and fixed technical solutions were and are not always existing. So technical solutions had to be developed under the constraints of new technology and regarding the existing mechanical and electrical environment in the car. LED technology in the forward external vehicle lighting is still in its infancy. This article shows that the technical solutions have now been developed and the first Full LED headlamp has become reality. The performance level of the main functions is equivalent to HID (High Intensity Discharge), giving safety advantages as they are expected for high end performing headlamps. The presented headlamp demonstrates that LED functions are able to replace all tungsten filament based solutions, giving energy saving potential and thus a significant reduction of CO2-emissions. Even in the limited construction volume of a sports car it is possible to integrate all functions in LED technology with equivalent lighting performance. Future fields of activity are to be found especially in the implementation of adaptive light systems and in the optimization of energy consumption. No doubt, LED will make its way into frontlighting by using the styling and energy saving opportunities.
