The economic matrix beam is needed on the market. In this study, Bi-Function matrix module is suggested to meet the needs. The study is carried out by approaching the minimizing size and the enhancing performance of the matrix headlamp including low beam and high beam. To find the solution, the study defined the target of the development and verified concepts of some optical modules which can meet the target. After that, I fixed the optical concept to realize the performance what we want. The optic and structure are designed and simulated by CATIA, SPEOS and Light tools. During the design, there are many kinds of problems. For example, Pattern gap between the low beam and high beam, structural and optical limitation of the optic, Color aberration, Material, Tolerance, Operation logic and so on. The study shows that all the solution what I approached to overcome side effects to meet the target performance. Those are not perfect solutions. And also one of them might be not a real solution on the market. But the study was trying to discuss all in terms of the solution. Finally, real mock-up module was made and tested by LMT machine. The light distribution was almost same as what I simulated. And it works well following the virtual logic which is designed by assuming certain driving condition. Unfortunately, the study could not include the result of real car testing about the matrix beam. It will be a next step of this study. At the end of thesis, I suggested the new technology for the future briefly. In the future, Autonomous cars are expected on the market mainly. The role of headlamp should be change to meet the new requirements of future market needs.
