Illumination system for vehicle interior reduces light density of surface lit by area light in accordance with dark adaptation curve for human eye, after switching off interior light

摘要

The method involves using at least one interior light (2) and least one area (5a,5b) light of lower intensity; an area is illuminated by the area light when the interior light is off. The light density of the surface lit by the area light is reduced in accordance with a human eye dark adaptation curve after switching off the interior light and/or switching on external lighting and/or falling below a defined light density in the vehicle. The method involves using at least one interior light (2) and an area of the device with at least one area light (5a,5b) whose light produces lower intensity than the interior light, whereby the area is illuminated by the area light when the interior light is off. The light density of the surface lit by the area light is reduced in accordance with a dark adaptation curve for the human eye after switching off the interior light and/or switching on external lighting and/or after falling below a defined light density in the vehicle interior. AN Independent claim is also included for an arrangement for vehicle interior lighting.
