Abstract
Future cars with (semi-) autonomous driving enable more use of interior lighting with special visual effects. This deals as well with interior materials – like plastics, wood, metals - which are illuminated or backlighted by RGB LEDs. We performed 3D BRDF measurements from a luminance imager and compare them to traditional goniophotometers. Perception test with 37 subjects for transflective materials show that there is a narrow width of backlight intensity for “pleasant” (not bothering) intensity. Such fundamental optical examinations enable special visual effects for future vehicles.
