Abstract

An interior aircraft lighting assembly (2) comprises: at least one infrared lighting device (22a, 22b, 22c) for emitting infrared light; at least one further lighting device (4, 26a, 26b, 26c) for emitting visible light; a lighting assembly controller (12) for controlling an operation of the at least one infrared lighting device (22a, 22b, 22c) and of the at least one further lighting device (4, 26a, 26b, 26c); a supplementary infrared lighting device controller (36); and a power supply network, which is configured for supplying electric power from the lighting assembly controller (12) to the at least one further lighting device (4, 26a, 26b, 26c). The supplementary infrared lighting device controller (36) is tapped into the power supply network. The lighting assembly controller (12) is configured to provide an electric trigger pulse on the power supply network for activating the at least one infrared lighting device (22a, 22b, 22c). The supplementary infrared lighting device controller (36) is coupled to the at least one infrared lighting device (22a, 22b, 22c) and is configured to enable power flow to the at least one infrared lighting device (22a, 22b, 22c) in response to detecting the electric trigger pulse, provided by the lighting assembly controller (12) on the power supply network; and the supplementary infrared lighting device controller (36) is configured to cause the at least one infrared lighting device 22a, 22b, 22c) to emit infrared light for an infrared lighting duration, which is longer than a duration of the electric trigger pulse.
