Abstract
Automotive headlamps equipped with high-resolution modulator technology can provide comfort and safety features like a glare-free high beam and road projections. Previous research has shown the importance of beam shaping for automotive headlamps with a peak of the illuminance in the center of the FoV for longer viewing range. The peak of the illuminance can be achieved through the use of a distorting optical system, which is proved for a homogenously illuminated DMD. However, DMD-based headlamps are limited in their use due to systemic disadvantages. In particular, luminous efficacy and contrast are advantages of µLED-Array over illuminated DMDs, which can be further exploited for improved automotive headlamps. In this paper, we present the optical design of a distorting µLED-Array-based headlamp. In particular, we address the challenges of optical design for lambertian emitters and compare the µLED-Array-based system with a DMD-based system. The use of distorting µLED headlamps is evaluated in conclusion.
