Abstract

An exterior aircraft light (1) comprises a housing (8) defining an interior space (9); a light output generation unit (3) comprising at least one light source (2); power supply electronics (10), coupled to the light output generation unit (3) for driving a light output of the exterior aircraft light (1) and a draining device (12) for draining the interior space (9). At least one of the light output generation unit (3) and the power supply electronics (10) is arranged within the interior space (9). The draining device (12) comprises a first drainage tube (14a) for receiving fluid (26), a second drainage tube (14b) for receiving fluid (26); and a fluid discharge port (19) for discharging fluid (26) out of the housing (8). Each of the first and second drainage tubes (14a, 14b) comprises a valve mechanism (15a, 15b) for selectively sealing and opening the respective drainage tube (14a, 14b) with respect to the interior space (9). Each valve mechanism (15a, 15b) comprises a valve portion (16a, 16b) and a sealing element (18a, 18b), arranged in the valve portion (16a, 16b) of the respective drainage tube (14a, 14b). The sealing element (18a, 18b) is movable within the valve portion (16a, 16b) under the influence of gravity. The valve portion (16a, 16b) and the sealing element (18a, 18b) are shaped and dimensioned such that the sealing element (18a, 18b), driven by gravity, opens the respective drainage tube (14a, 14b), when the respective drainage tube (14a, 14b) is oriented in a draining orientation; and seals the respective drainage tube (14a, 14b) in an air-tight manner, when the respective drainage tube (14a, 14b) is oriented in a sealing orientation.
