Aircraft headlight, aircraft comprising an aircraft headlight, and method of operating an aircraft headlight

An aircraft headlight, comprising:

• at least one visible light source for emitting a headlight light output;
• a light transmissive cover, at least partially covering the at least one visible light source;
• and
• at least one infrared emitter for emitting infrared radiation;
• wherein at least 90% of radiation energy, comprised in the infrared radiation emitted by the at least infrared emitter, is emitted within a predefined wavelength range;
• wherein the light transmissive cover allows at least 25% of the radiation energy, which is emitted within the predefined wavelength range, to pass through the light transmissive cover;
• wherein the light transmissive cover has an inner light input surface, an opposing outer light output surface and at least one lateral surface extending between the inner light input surface and the outer light output surface,
• wherein the at least one visible light source is arranged opposite to the inner light input surface so that the headlight light output emitted from the at least one visible light source enters into the light transmissive cover through the inner light input surface and exits from the light transmissive cover through the outer light output surface, and
• wherein the at least one infrared emitter is arranged at the at least one lateral surface of the light transmissive cover so that the infrared radiation emitted by the at least one infrared emitter enters through the lateral surface into the light transmissive cover.
