Abstract
The invention relates to a flat light-emitting lighting device for a vehicle, and to a method for providing emergency energy supply to the lighting device. A shallow installation depth and low power consumption of the lighting device may be ensured by the use of a flat OLED illumination device. Due to the low power consumption of the flat OLED illumination device, an emergency energy supply may be integrated without this increasing the installation depth. Such flat lighting devices, which in the case of emergency are self-supplying, may, for example, be used in aircraft in order to, with suitable icons or text, indicate escape routes or other emergency-relevant information.
