The invention relates to a method for controlling a lighting system in an aircraft cabin with a multiplicity of lighting units (3) arranged distributed in the aircraft cabin, each of which comprises a controller (4) for controlling RGB light-emitting diodes (5) connected thereto, and a central processor (1) connected to each of the controllers (4) for the purpose of data exchange, each controller (4) comprising a storage unit (6) having a number of scene programmes (P1, P2, P3) stored therein for controlling in each case one scene, a scene being a predetermined change with time of a luminous behaviour of the RGB light-emitting diodes (5), and control data records being transmitted to the controllers (4) from the central processor (1) for controlling an overall luminous behaviour generated by means of the multiplicity of lighting units (3), each of which control data records contains at least one scene programme identification information (PI) and one synchronization information (SI) for controlling the sequence of the scene programme (P1, P2, P3) corresponding to the scene programme identification information (PI) with time.
Method for controlling a lighting system in an aircraft cabin with a multiplicity of lighting units (3) arranged distributed in the aircraft cabin, each of which comprises a controller (4) for controlling RGB light-emitting diodes (5) connected thereto,
Method according to one of the preceding claims, the control data record comprising a brightness information for controlling a brightness (H) of the scene generated by means of the scene programme (P1, P2, P3).
Method according to one of the preceding claims, the lighting units (3) being split into at least two groups (G1, G2) and the control data record containing a synchronization information item (SI) specific for each of the groups (G1, G2).
Method according to one of the preceding claims, the control data record containing a scene programme identification information item (PI) specific for each of the groups (G1, G2).
Method according to one of the preceding claims, the control data records being continuously newly generated by the central processor (1) in accordance with a predetermined algorithm and being transmitted to the controllers (4) at predetermined time intervals.
Method according to one of the preceding claims, a content of the control data records being changeable by means of manually input control information.
Method according to one of the preceding claims, the control data records being transmitted to the controllers (4) at time intervals of 100 to 300 ms, preferably 150 to 250 ms.
Method according to one of the preceding claims, at least one scene programme (P1, P2, P3) being transmitted to the controllers (4) from the central processor (1) in an update mode.
