LED technology in automotive headlamps: driving more safely with adaptive lighting systems

This thesis is focused on automotive headlamps, explaining in detail the adaptive lighting systems especially the matrix systems and high denition headlamps. I personally believe that this technology will lead to safety improvements on the night driving conditions. To allow the understanding of matrix technology some basic knowloedge on the automotive headlamps are necessary. Starting from the simplest application and evolving to the most complicated ones. When I said that the matrix technol ogy will improve the safety on our roads, it's not because this technology is not yet implemented on series vehicles but because the percentage of the vehicles equipped with matrix headlamp is still very low. As always the most advanced technologies are re served only for some versions of premium vehicles due to cost targets. But what is our role as engineers? Obviously the engineering community couldn't help the car makers nancially to implement the matrix technology on the headlamps but could for sure incr ease the awareness of the users towards this technology. Talking, explaining and demonstrating the advantages of such important improvement in safety will create a desire to the nal users to use the matrix technology for themselves and the others in their vehicles. Time is a very important factor in technology allowing as the years go by to reduce as much as possible the cost for implementation. I want to remember the example of ABS systems, that started with implementation on the premium vehicles, then exp anded the application in all the vehicles and nally become obligatory to every vehicle by the norms. My wish for the matrix technology is to be available even to the cheaper vehicles in order to increase the safety on the roads.
