Abstract

This paper propose an optical design of adaptive automotive headlight system with advanced light-emitting diodes (LEDs) and digital micro-mirror device (DMD). In recent days, safety of on-road drive plays the role at automotive industries so that fast response of adaptive automotive headlight system becomes a critical issue especially in mountain road drive. In order to integrate the function of low and high beam into a single headlight without sacrifice of volumetric size of whole system, a DMD is employed in this optical design. Simulation shows that new optical design not only promotes light efficiency but also reduce volumetric size. Besides, light from adaptive automotive headlight system could make the projected light much suitable for drivers according to individual driver's vision experience. Results show that volumetric size of all system might be reduced up to 30 percent but light efficiency could be promoted up to 20 percent.
