Multi-layered arrangement of foil layers for supplying power to light emitting diodes in aircraft cabin lighting

A light system in an aircraft includes an electrical power source (4), individual light emitting diodes (2A,2B,2C) arranged in a cabin of the aircraft, and a multi_layered conductor arrangement (1) connecting the light emitting diodes to the power source. The multi_layered conductor arrangement includes electrically conductive foil layers (F1,F2,F3) separated from one another by respective interposed insulative layers (I1,I2), and may be disposed on a curved honeycomb ceiling panel of the aircraft cabin. The foil layers form conductive circuits connected to the power source through a switching arrangement (3) that selectively individually energizes the individual conductive circuits. The foil layers are differently patterned so that the diodes are each connected to and isolated from the respective pertinent layers. This avoids individual wiring and can provide different patterns, sequences, or lighting schemes of several independently controlled groups of diodes.
