Automotive interior illumination: challenges and requirements

Car interiors have been evolved towards the so-called driver working place and in future to (autonomous) cars as third living space for leisure and work. Entertainment systems, driver assistance, large displays, and light design have revolutionized the design as well as the expectations of drivers and passengers. Material, displays, and ambient light will create a new environment for passengers in the future. This paper focuses on advanced interior lighting by a new integrated smart embedded LED (ISELED) concept which enables beyond state-of-the-art light effects including contour lighting and daylight visibility at reduced effort compared to today's LED interior lighting approaches. The ISELED concept is an open alliance eco-system along the supply and value chain. Major automotive lighting trends as well as challenges and solution will be described.
