1. An interior aircraft lighting assembly, comprising:
at least one infrared lighting device for emitting infrared light;
at least one further lighting device for emitting visible light;
a lighting assembly controller for controlling an operation of the at least one infrared lighting device and of the at least one further lighting device;
a supplementary infrared lighting device controller; and
a power supply network, which is configured for supplying electric power from the lighting assembly controller to the at least one further lighting device;
wherein the supplementary infrared lighting device controller is tapped into the power supply network;
wherein the lighting assembly controller is configured to provide an electric trigger pulse on the power supply network for activating the at least one infrared lighting device;
wherein the supplementary infrared lighting device controller is coupled to the at least one infrared lighting device and is configured to enable power flow to the at least one infrared lighting device in response to detecting the electric trigger pulse, provided by the lighting assembly controller on the power supply network; and
wherein the supplementary infrared lighting device controller is configured to cause the at least one infrared lighting device to emit infrared light for an infrared lighting duration, which is longer than a duration of the electric trigger pulse.
