LED headlamps enable unique styling solutions and a range of beam functionalities. After the first highly sophisticated designs and solutions, the range is extended to the mid and lower class with more essential designs and basic functionality. The headlamp architecture has to reflect the various levels of complexity. Engineers in the industry are currently trying to identify the building blocks that allow supporting the various levels in an economical way by reusing components and construction principles. The LED light source is an important element that interacts strongly with the system. As a light source manufacturer we are faced with the requests to come forward with sources providing superior styling flexibility, ease of use and system cost reduction. In this paper, we will show options, how this can be supported.

Today, LED automotive exterior lighting is already widely used on high end and upper middle class vehicles. We see already first examples of application as the standard lighting solution even in the mid class segment. A compact design and the feasibility of car life sealed solution is a strong argument to use LEDs for CHMSLs. Long lifetime and new styling opportunities speak for LEDS in front or rear position lights as well as in daytime running lamps;. Mainstream penetration of LED lighting solutions will first happen for functions where the benefits of LEDs have the highest positive impact and where this value can be realized in the most cost-effective way. During the different phases of the introduction of LEDs different requirements dominate the decision process. Providing unique styling opportunity and showing advanced technical functionality is leading for the early adopters.
