Abstract: An optics support system for an aircraft light comprises: a multi-layer support board, having a main plane of extension; an LED arranged on the multi-layer support board; a first set of leg stands, positioned around the LED, wherein the first set of leg stands provides first abutment surfaces for arranging an optical element, having a corresponding set of legs, over the LED in a first orientation; and a second set of leg stands, positioned around the LED. The second set of leg stands provides second abutment surfaces for arranging the optical element over the LED in a second orientation; and the first abutment surfaces and the second abutment surfaces are at different heights in a z-dimension of the multi-layer support board, orthogonal to the main plane of extension.

Abstract: An aircraft passenger service unit includes infrared sensor configured for detecting infrared radiation and for providing a corresponding sensor output, and a controller, which is configured for receiving and evaluating the sensor output provided by the infrared sensor. The infrared sensor is an infrared sensor array configured for detecting infrared radiation emitted within a plurality of spatial sectors covering a detection area below the aircraft passenger service unit; and the infrared sensor array is configured for detecting the infrared radiation individually for each spatial sector and for providing individual sensor signals for the plurality of spatial sectors. The infrared sensor array is configured such that each passenger seat arranged within the detection area is covered by at least two of the plurality of spatial sectors, respectively; and the controller is configured for determining a passenger seating position within a passenger seat from the individual sensor signals.

Abstract: 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.
