To guide a passenger to the general location of his assigned seat in an aircraft cabin, the cabin is divided into several cabin zones that are individually identified by different colors of illumination, for example a yellow cabin zone, a red cabin zone and a blue cabin zone. Each service class can correspond to one cabin zone or encompass plural cabin zones. Lighting devices arranged in the cabin are activated to provide illuminating light having the appropriate allocated illumination color in each respective cabin zone. The lighting devices are preferably ceiling lights, sidewall lights, and / or window funnel lights, controlled from a flight attendant panel via a lighting controller. A passenger ticket displays the passenger's assigned seat number and letter, and also the color of the cabin zone in which the assigned seat is located.

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.
