Embodiment Construction

[0034] figure 1 An aircraft exterior light unit 2 according to an exemplary embodiment of the invention is shown in a perspective view. The aircraft exterior light unit 2 may be mounted to an aircraft, such as an aviation aircraft or a helicopter, in various locations. For example, the aircraft exterior light unit 2 can be installed on the tail or wing tip of an aviation aircraft.

[0035] The aircraft exterior light unit 2 comprises a support plate 4 to which an LED 6 and a near end of life detector 8 are mounted. The LED 6 is mounted substantially at the center of the support plate 4 . Near end of life detector 8 is spaced from LED 6 along axis A-A. The axis A-A is the horizontal axis of the aircraft exterior light unit when assembled to the exterior of the aircraft.

[0036] The aircraft exterior light unit 2 further comprises a transparent optical element 10 made of silicone. The transparent optical element 10 is overmoulded over the LED 6 and the end-of-life detector...

Abstract

The present disclosure relates to an aircraft exterior light unit (2) comprising: a support plate (4); LEDs (6) mounted to the support plate; an end-of-life detector (8) for sensing all the light output level of the LED, the near end of life detector mounted to the support plate; and a transparent optical element (10) for shaping the output light intensity distribution of the aircraft exterior light unit, wherein the transparent An optical element jointly encloses the LED and the near end of life detector, wherein light from the LED passes through the transparent optical element to the near end of life detector.

Description

technical field [0001] This invention relates to aircraft exterior lighting. In particular, the present invention relates to aircraft exterior light units having near end of life detectors. Background technique [0002] Almost all aircraft are equipped with external light units. In particular, large airliners have a wide variety of exterior light units. The exterior light unit is provided for a wide variety of different purposes, such as allowing passengers and / or crew to view the exterior, passive visibility, signaling purposes, and the like. Examples of such external light units are navigation lights (also called position lights), beacon lights, anti-collision lights, wing scan lights, landing lights, taxiing lights, runway turning lights and the like. [0003] Aircraft exterior light units are exposed to extremely hazardous conditions. They must withstand large aerodynamic forces as well as large temperature changes. In particular, both extremely low temperatures due...
