摘要： An aircraft light comprises a support board; a light source, arranged on the support board; a first optical element, which is at least partially light transmissive, which is arranged over the light source, and which is fixed to the support board; and a second optical element, which is at least partially light transmissive, wherein the first optical element is interposed between the light source and the second optical element. The first optical element has a first engagement portion and the second optical element has a second engagement portion. The first engagement portion and the second engagement portion establish a positive fit between the first optical element and the second optical element. At least a portion of light, which is emitted by the light source in operation, passes through the first optical element and through the second optical element.

摘要： A navigation light system for an unmanned aerial vehicle, such as a multicopter type unmanned aerial vehicle, includes: a plurality of light emission units. E of the plurality of light emission units has a unit-specific light emission direction and is configured to provide a light output around the unit-specific light emission direction. Each of the plurality of light emission units includes a multi-color light source capable of emitting red light, green light, and white light. The plurality of light emission units are arranged to jointly provide a navigation light pattern around the unmanned aerial vehicle and wherein the light outputs of adjacent light emission units have an overlap the navigation light system is configured to operate each of the plurality of light emission units depending on a relation between a momentary flight direction of the unmanned aerial vehicle and the respective unit-specific light emission direction.
