1. An aircraft passenger reading light, comprising:
at least one reading light source, which is arranged for emitting visible light in a reading light emission direction for illuminating a passenger reading space with visible light;
at least one infrared light source, which is arranged for emitting infrared light in an infrared light emission direction for illuminating a passenger sitting space with infrared light; and
at least one common optical element;
wherein the infrared light emission direction is inclined with respect to the reading light emission direction, and
wherein visible light emitted by the at least one reading light source and infrared light emitted by the at least one infrared light source are directed into the reading light direction and the infrared light direction, respectively, by the at least one common optical element.
