A student team from Rose-Hulman Institute of Technology applied a freeform optical engineering concept for automotive LED headlight and has won a prize in the 2018 Global Capstone Design Fair held in South Korea. The students’ prototype utilizes freeform optics which requires less working parts than current headlight models. By utilizing molded plastic instead of the current practice of metal reflector cones, the headlight could be easier and cheaper to manufacture. With non-sequential ray tracing, the students designed a 3-D freeform lightguide to direct the light...
